Abstract
The invention provides a scissor type car arrester, and belongs to the technical field of equipment trains of underground coal mine working faces. The scissor type car arrester mainly solves the problems that in the prior art, two-sheet-type installing is adopted, dismounting is not convenient, time is wasted, three fastening bolts are prone to fastening asymmetry, and fake clamping is caused. The scissor type car arrester comprises half scissors, a hinge assembly and locking bolts. The half scissors include the front half scissor and the back half scissor. The scissor type car arrester is characterized in that upper clamping arms of the half scissors are provided with bolt through holes and inner grooves, the inner grooves are formed in the front ends of the upper clamping arms, the inwards-concaved radian of the inner grooves is matched with the edge of a wheel, and a lower clamping nozzle is provided with an inner hook. The hinge assembly comprises a front hinge pin pipe, a back hinge pin pipe and a hinge pin, and the front hinge pin pipe is hinged to the back hinge pin pipe through the hinge pin. In the using process, the locking bolts penetrate through the bolt through holes in the upper clamping arms of the half scissors and are screwed through nuts.
Description
Technical field
The invention belongs to working face equipment train technical field under coal mine, be specifically related to scissor stop device.
Background technology
On the equipment train of driving surface, carrying equipment such as moving change, emulsification pump and central station of floating dock, is driving surface heart.Therefore, guarantee that the stable of train seems particularly important.
The stop device of prior art adopts two-piece type, by three bolts, two-piece type stop device fastener is held up traffic in orbit, and it in use exists following shortcoming:
1, install, dismantle inconvenience, lose time.Before being installed, rail meter needs three screws to pull down completely, and then symmetrical being stuck on track, the screw of screwing on one by one.Subsurface environment dark and in help operation distance little, wrench operated inconvenience.
2, three bolts are prone to fastening asymmetricly, cause " false stuck " situation, can become flexible again, thereby cause serious potential safety hazard after being knocked.
3, " two-piece type " easily squeezes tong, causes personal injury.
Summary of the invention
The present invention seeks to solve the problem that prior art exists, scissor stop device is provided.
The present invention solves the problems of the technologies described above the technical scheme of taking to be:
Scissor stop device, comprises half scissors, hinge assembly and lock bolt; Described half scissors comprises preposition half scissors and rearmounted half scissors; Be characterized in: on the top clamp arm of described preposition half scissors, be provided with bolt through-hole and inner groovy, front end and indent radian that described inner groovy is positioned at top clamp arm mate with felly, bottom clamps mouth interior crotch is set; Equally, on the top clamp arm of described rearmounted half scissors, be also provided with bolt through-hole and inner groovy, front end and indent radian that described inner groovy is positioned at top clamp arm mate with felly, and bottom clamps mouth interior crotch is also set; Described hinge assembly comprises preposition hinge central siphon, rearmounted hinge central siphon and hinge, wherein preposition hinge central siphon is fixed in the middle part of preposition half scissors, rearmounted hinge central siphon is fixed in the middle part of rearmounted half scissors, and preposition hinge central siphon is hinged by hinge and rearmounted hinge central siphon; When use, lock bolt is through being arranged on the bolt through-hole on half scissors top clamp arm and passing through nut screwing clamping.
The present invention compared with prior art, has following beneficial effect:
Because the present invention is by preposition half scissors and the hinged structure of rearmounted half scissors, only need 1 bolts to carry out fastening, work efficiency is high, and uses simple, laborsaving.

Detailed description of the invention
As shown in Figure 1, scissor stop device, comprises half scissors, hinge assembly 3 and lock bolt 7; Described half scissors comprises preposition half scissors 1 and rearmounted half scissors 2; As shown in Figure 2, be provided with bolt through-hole 4 and inner groovy 10 on the top clamp arm 9 of described preposition half scissors 1, front end and indent radian that described inner groovy 10 is positioned at top clamp arm 9 mate with felly, and bottom clamps mouth 5 interior crotch 6 is set;
Equally, as shown in Figure 3, be also provided with bolt through-hole 4 and inner groovy 10 on the top clamp arm 9 of described rearmounted half scissors 2, front end and indent radian that described inner groovy 10 is positioned at top clamp arm 9 mate with felly, and bottom clamps mouth 5 interior crotch 6 is also set; Described hinge assembly 3 comprises preposition hinge central siphon 11, rearmounted hinge central siphon 12 and hinge 13, wherein preposition hinge central siphon 11 is fixed in the middle part of preposition half scissors 1, rearmounted hinge central siphon 12 is fixed in the middle part of rearmounted half scissors 2, and preposition hinge central siphon 11 is hinged by hinge 13 and rearmounted hinge central siphon 12; When use, as shown in Figure 4, lock bolt 7 is through being arranged on the bolt through-hole 4 on half scissors top clamp arm and passing through nut screwing clamping.
Using method:
When the present invention uses, nut on lock bolt 7 is unscrewed and extracted, open bottom and clamp mouth 5, be stuck on guide rail 8, and make inner groovy 10 towards wheel, lock bolt 7 is penetrated to bolt through-hole 4 again and pass through nut screwing clamping, when train wheel and inner groovy 10 coincide, stop device enters mode of operation.
