摘要： PURPOSE: To obtain highly reliable inspection results automatically. CONSTITUTION: A plurality of range finding sensors 5 for measuring the distance from a reference point to different points on a rail presser 4 for jointing rails R through fastening bolts 3, and a controller 6 for operating the fastening state of the fastening bolt 3 based on signals from the range finding sensors 5 are mounted on a vehicle traveling on the rail. The controller 6 comprises means 61 for converting an analog range finding signal received from the range finding sensors 5 into a digital range finding signal, means 62 for deciding the fastening state of the fastening bolt 3 by operating the difference between the range finding values from a plurality of range finding sensors 5 based on the converted digital range finding signal, and means 63 for outputting the decision results of the means 62. The means 62 decides that the fastening bolt 3 is loosened when the difference between the range finding values exceeds a previously inputted allowable value.

摘要： PURPOSE:To improve the detecting efficiency in a looseness detecting device for rail fastening device by providing, on a truck, a looseness detecting means for detecting the displacement of a pressing member for pressing a rail to a sleeper in the restoring direction from the proper fastening state. CONSTITUTION:Displacement sensors 11, 12 are provided as looseness detecting means of a pressing member 1 for pressing a rail to a sleeper on a truck traveling on the rail. The displacement sensors 11, 12 detect the displacement of the pressing member in the restoring direction from the proper fastening state and input it to the memory part 19 of a controller 18 through an A/D converter 17. The controller 18 stores this input signal, then calculates the displacement by a displacement arithmetic part 20, and compares it with an allowable displacement in a looseness judging part 21 to judge the presence of looseness. When looseness is judged, it is displayed on a display part 23, and also turned into a data base by a data processing part 22.

摘要： PURPOSE:To reduce pressure loss in a mixer by forming an air passage in the lower part of an impeller casing, which is in communication with the bottom of a tank, in such a way as parallelly with the shaft of the impeller and across the vane rotating position, and by inclining each vane force or aft viewed in the rotating direction. CONSTITUTION:Each vane 7 of an impeller 8 is formed inclined force or aft in the rotating direction. An air passage 5 is formed in the lower casing 13 in parallel approx. with the shaft of impeller 8 and in such a way as across the lower rotating position of each vane 7. Thereby the air flowing through this air passage 5 will pass straight the rotating position of vane 7, which can reduce the loss of air pressure within a mixer 1 concerned. Because of inclined vanes, part of the compartment at the periphery of the impeller will overlap with the impeller radial direction at all times to prevent isolation of compartments between by vanes, provide uniform flow, reduce the pressure loss, and accomplish prevention of the air passage from blockage.

摘要： PURPOSE:To automatically detect the looseness in a rail fastening unit by preparing a storage device for detection sensor outputs of bolt fastening pressure in the rail fastening unit, mounting a data processor on a truck, sending/ receiving the data, and comparing the pressures with reference values. CONSTITUTION:In respective rail fastening units the bolt fastening pressure is detected by a pressure sensor 12, the pressure data is stored by an auxiliary storage device 16 of a tag 10, and it is transferred to a CPU 18. The CPU 18 compares the pressure data with preset fastening pressure reference values to judge whether or not it is normal, and then transfers the result as well as address information and pressure data to the device 16. While a truck is running, a controller thereon issues an address-designated timing signal and the CPU 18 reads respective data in the device 16 after confirming the address and transmits the data through an input/output device 19. After the controller receives it, it indicates them on a display part and stores them in a data processing part. Thus, while the truck is running, the judging data is taken in the controller, resulting in automatic detection.

摘要： PURPOSE: To reduce a construction period by constituting this excavation equipment of an excavation arm, a support arm having a soil-discharging means, screw conveyors in both arms, and both fixed and rotary casings and providing a taking-in means to an opening for taking-in soil. CONSTITUTION: This excavation equipment is constituted of a base machine 1, an excavation arm 3 of a cylindrical support arm 2, and a belt conveyor 4. The support arm 2 is supported by a revolving body 21 and a hydraulic cylinder 22 so as to rise and fall. Screw conveyors 23, 33 are disposed in both arms 2, 3 and respective pipes 25, 31 are fitted to be rotatable around the horizontal axis (a). The upper end of a rotary casing 35 of the excavation arm 3 and the conveyor 33 are supported at the lower end of the fixed casing 34 so as to be rotatable around an axis (b). Further, an opening 352 for taking-in soil is formed in the lower end rib 36 of the rotary casing 35. In this way, ground can be excavated even in a narrow space.

摘要： PROBLEM TO BE SOLVED: To simplify the execution of the end of an excavating groove by excavating while transferring the mounting position of a lateral cylinder in lateral direction and in order along a main frame and moving a vertical frame from one end of a horizontal member to the other end. SOLUTION: A head side rear end part 33a and a rod side top end part 33c of a lateral cylinder 33 installed on an upper horizontal member 22 are connected to or disconnected from the upper horizontal member 22 through multiple lock pins arranged on the upper horizontal member 22. Also, with either of the rod side top end part 33c and head side rear end part 33a of the lateral cylinder 33 connected to the upper horizontal member 22 of a main frame 21, a rod 33b is telescoped. A lateral cylinder 36 installed on a lower horizontal member 23 in the same structure is interlocked to the lateral cylinder 33. By this, with the upper and lower horizontal members 22 and 23 of the main frame 21 used as a guide, a leader is moved slidably in lateral direction along the main frame 21. Thus replacing work can be performed easily and in a short time, and the execution at the end of an excavating groove becomes easier.
