摘要： PURPOSE:To remove easily core sand in short time with less operator's fatigue by using a cutter in the stage of removing the core sand sticking between the two semicircular iron cores in a cast iron pipe when said pipe is cast. CONSTITUTION:Core sand 2 sticking to a cast iron pipe 3 produced by casting is removed in order to remove two iron cores 1 from said pipe. The core sand 2 is removed by cutting with a cutting machine 10 provided with a cutter for the above-mentioned purpose and the iron cores 1 are removed. The cutting machine 10 is provided with a supporting bracket 14 turning freely around a pin 15 to a bracket 13 attached to a swiveling body 12 on a chassis 11 and is provided with an arm 16 projecting from said bracket. The rod side of a swing cylinder 17 is pinned 10 to the arm 16 by a pin 19 and a gate type frame is attached oscillatably to a base frame 33 via a boom 21. Cutter cylinders are provided in the lower right and left parts of said frame and cutters are respectively attached to the rods thereof. The sticking core sand 2 is ground away by said cutters, by which the iron core is easily removed without entry of the operators in the cast iron pipe.

摘要： PURPOSE:To provide a coupling device which can reduce the energy loss in the shift of a vehicle and can omit a brake hose, etc., connected between the vehicles. CONSTITUTION:A fixed plate 11 is installed through a pair of supporting arms 9 at the rear edge part of a first vehicle 3, and an engagement block 13 forming a recessed section is installed on both the sides of the upper edge part of the fixed plate 11. At the front edge part of a second vehicle 5, an elevator plate 19 which is supported in an elevation enabled manner by a link mechanism 17 is arranged, and between the elevator plate 19 and the second vehicle 5, the basic edge part is pivotally installed at the upper edge part of the second vehicle 5, and a pulling-up cylinder 25 which is constituted so that the top edge part of a piston rod 25a is pivotally installed at the lower edge part of the elevator plate 19 is arranged. The elevator plate 19 is raised and lowered by advancing the retreating the pulling-up cylinder 25, and when the elevator plate 19 is raised, the upper edge part is engaged with the engagement part 13a of the engaging block 13.

摘要： PURPOSE:To improve the stability at the time of work by providing leg rods suspended downward from the section of a traveling truck which can be run to be laid on a revetment embankment with a mounted service machine main- body, with a clamp pincher and a guide roller wheel. CONSTITUTION:A service machine is conveyed in site with a trailer and is mounted on an embankment D for a revetment by a crane or the like. After that, a traveling truck section A with a mounted service machine main-body 4 and endless rails can be run to be laid on the embankment D. Then, leg rods 14 suspended downward on both sides of the truck section A are provided with a tumbling-proof clamp pincher B, and a guide roller wheel C for regulating the induction of the truck section A in the direction of the embankment D. As a result, work can be executed with safety.
