摘要： PURPOSE:To drive a pile deeply into the ground while holding a leader at a constant height by providing holders for fixing the relative positions of both pipes in a multi-stages type telescopic casing pipes at arbitrary positions. CONSTITUTION:A casing pipe 5 is composed of a main part and an extension 5', and the inner peripheral surface of a lower stage casing pipe 4 is moved vertical. Further, a pipe 122 is fitted in the pipe 5, and branch pipes 1231, 1232 are laid. Then, holders 1201, 1202 are secured to the pipe extension 5', and the fluid pressures in the pipe 122 and the branch pipes 1231, 1232 are increased and decreased under remote control so as to lock and release the pipe 5 and the pipe extension 5'. With this arrangement, it is possible to retract the pipe 5 during a sand pile driver being moved, but to extend the same during the pile being driven, thereby it is possible to drive a pile deeply into the ground.

摘要： PURPOSE:To make it possible to automatically actuate a lock device for a hatch cover, by associating the rotation of a twist lock pin of a crane spreader adapted to be used for opening and closing the hatch cover, with the operation of the lock device. CONSTITUTION:When a hatch cover is unlocked, a twist lock pin 5 of a crane spreader is inserted into a lifting recess 6 and is simultaneously fitted into a bifurcated holder 7. When the twist lock pin 5 is rotated by a drive means, the bifurcated holder 7, a rotary lever 9 and a horizontal rod 13 are moved in association with the rotation of the twist lock pin 5, and therefore, an L-like lever and an edge side rod 22 are moved in association with the former to turn a hook 29. Thereby, the locking between the hook 29 and a locking fixture 33 is released. Meanwhile the twist lock pin 5 is rotated in the opposite direction when the hatch cover 2 is locked.

摘要： PURPOSE:To keep hatch covers in a rain and wind tight state or to release the state automatically, by turning a small cover in a longitudinal passage by actuating a turning mechanism such that it covers a space between confronting drain passage when both adjacent hatch covers are placed on an upper portion of an edge member. CONSTITUTION:When hatch covers 4, 5 are lowered to prescribed closing positions and a gasket seal 7 is seated on a hatch cover edge member 2 pressed against the upper portion of a seal bar 3, an end 21a of a lever 21 is depressed by a pressing plate 23 and its other end 21 is lifted to move a link plate 18 upwardly against a spring 12 so that a lever 16 turns clockwise about a pin 11. Then, a small cover 14 in a longitudinal passage turns to a position shown by a solid line, a gasket 15 is pressed into contact with the upper portion of the seal bar so that rain and water tightness is created automatically as the hatch covers 4, 5 are closed. Next, when the hatch covers 4, 5 are opened, the rain and wind tightness is automatically released by lifting them, respectively. Thus, when a plurality of hatch covers are opened, an order for opening them is not necessary to be set. Therefore, rain and water tightness is automatically set by opening and closing hatch covers.

摘要： PURPOSE:To freely open and close plural hatch covers, by parallelly movably providing a movable longitudinal drain plate in the transverse direction of a longitudinal drain groove part, which protrudes to both side walls of a central hatch cover, and driving the movable longitudinal drain plate through a recess metal vertically movably provided in a top plate of the central hatch cover. CONSTITUTION:Plural hatch covers of central, right and left hatches are arranged in a large hatch opened over almost the whole width of an upper deck in a container ship or the like. A longitudinal drain groove part 26 is provided protruding to a part opposed to right and left hatch covers 6 in both side walls of a central hatch cover 5, and a movable longitudinal drain plate 25 is parallelly movably provided in the lateral direction transversing the point end upper of a flange part 26a of said longitudinal drain groove part 26. And the movable longitudinal drain plate 25 performs its lateral movement through a driving lever 18 interlocking to the vertical movement of a movable recess metal 8 provided in a top plate of the central hatch cover 5. By this constitution, the large hatch, which enables its setting plural hatch covers to be opened and closed freely in the successive order, additionally enables each hatch cover to surely obtain its tightness for wind and rain.

摘要： PURPOSE:To make the restriction on the removal order of multiple hatch covers unnecessary by parallelly moving a longitudinal drain receiving trough to both extended and withdrawn positions in the horizontal plane interlockingly with the rotation of a twist lock pin. CONSTITUTION:When a hatch 2 is to be closed, a hatch cover 4 supported by a twist lock pin 6 fitted to a crane spreader 7 is mounted on the hatch 2, the twist lock pin 6 is rotated 90 deg. so that it can be released from the hatch cover 4, and at the same time, a horizontal rod 11 is extended as the twist lock pin 6 is rotated, a drain receiving trough 13' fitted to the rod 11 reaches the boundary with the adjacent hatch cover 4, the rain water passing the gap between them is received and discharged. When the hatch cover 4 is to be opened, the twist lock pin 6 is inserted into the hatch cover 4 and is rotated 90 deg. to be engaged with the hatch cover 4, the rod 11 is shortened by its rotation, the drain trough 13' is withdrawn and removed from the adjacent hatch cover 4, thus the hatch cover 4 can be opened.

摘要： PURPOSE:To reduce the weight and size of a fastener by engaging or disengaging the lever of a fastening bolt with/from a guide groove provided on a bolt holder through a hook plate, and whereby carrying out feeding and fastening of the fastening bolt through the operation of a nut runner and the hook plate. CONSTITUTION:When a nut runner 5 is rotated, a nut 8 is rotated, and a lever 12 is slid by the rotation of the nut 8 in a guide groove 6a of a bolt holder 6 while a fastening bolt 10 is slid to the left, and when the front end of the fastening bolt 10 is in contact with the bottom of a fastening hole 9 of the body 8 to be fastened, the rotation of the nut runner 5 is stopped. A fastening hole 19 and the fastening bolt 10 are engaged with one another by pushing the lever 12 by a fluid cylinder through a hook plate 16 and by rotating the fastening bolt 10 by 90 deg.. The fastening bolt 10 is receded when the nut runner 5 is rotated in reverse, and the fastening bolt 10 and the nut 8 are fastened with one another, and the fastening is thus completed.

摘要： PURPOSE:To efficiently and safely attach and detach a formwork at high precision by providing the wall parts of a panel piece so that the wall parts can be mutually made impulsive and erecting a horizontal expansion mechanism between the panel piece and a main frame along a diagonal line and erecting a vertical expansion mechanism between the main frame and a frame of the lower part. CONSTITUTION:A formwork device is equipped with a formwork panel 1 described below, a main frame 2 arranged in the inside thereof and a lower-part frame arranged in the lower part thereof. In the formwork panel 1, four pieces of panel piece which is mutually intersected at right angle and has two wall parts (a) are combined and thereby a nearly square horizontal cross section is formed. In order to enlarge and shrink the formwork panel 1, two wall parts (a) of the panel piece which mutually adjacently form one side of a square are provided so that the respective tip edges are overlapped and can be made impulsive. Moreover a horizontal expansion mechanism 5 is erected between the panel piece and the main frame 2 along the diagonal line of the square and further a vertical expansion mechanism is erected between the main frame 2 and the lower-part frame.
