Abstract
The utility model provides a mine railway railcar checking cylinder stroke adjustment spanner, mainly by wrench end, connector, ratchet, handle and wear the round pin and constitute, the connector be the splint formula, and two splint one end at the connector are fixed through fixed connection round pin to the wrench end, and two splint other ends are connected one and are worn the round pin, wear to sell both ends and fix with the nut, install a ratchet on wearing the round pin, operating handle one end is equipped with the pawl to cooperate with the ratchet of wearing on the round pin. This instrument simple structure, with low costs, dependable performance are used well at the scene, the maintenance personnel of repairing hold the handle, block adjusting nut with the wrench end, utilize the one -way intermittent movement adjusting nut elasticity of lever principle and ratchet to reach the mesh of adjustment checking cylinder piston stroke, it is narrow and small fully to have solved checking cylinder piston department space, and nearby railcar sand pipe and brake head had both been protected to the unable deep problem of ordinary spanner, can make things convenient for attendant and maintenance to repair personnel's operation again, has guaranteed the adjustment effect.
Description
Technical field
This utility model relates to a kind of brake cylinder piston travel adjusting nut solving heavy section car and cannot adjust and the device of fastening problems because of limited space.
Background technology
Existing heavy section car is along with the abrasion of brake shoe in utilization, and its piston travel also can change therewith, as being adjusted not in time, then can have a huge impact for the braking effect of locomotive and permutation car.But when brake cylinder piston travel is directly adjusted by crew, due to the design reasons of railcar self, the installation site of its sand pipe and brake head, near checking cylinder piston, causes adjusting limited space, it is impossible to effectively tighten adjusting nut.If things go on like this it is easily caused brake clearance adjusting screw nut to damage and the inconvenience of crew's operation, extends the activity duration.This is not only bad for the current check of railcar and maintenance, a potential safety hazard in railway transportation especially.
Summary of the invention
The purpose of this utility model is: design one adjusts spanner, when deviation occurs in brake cylinder piston travel, it is possible to fastens Traffic control system nut in narrow space or loosens, thus reaches to adjust checking cylinder stroke, it is ensured that braking effect.
Realize this utility model purpose to be adopted the technical scheme that: this device is mainly by driving end, adapter, ratchet, handle and wear pin and constitute, adapter is clamping plate type, driving end is fixed connecting pin through one and is fixed on two clamping plate one end of adapter, two clamping plate other ends connect one and wear pin, wear pin two ends nut and fix；Wearing one ratchet of installation on pin, operating handle one end is provided with ratchet, and matches with the ratchet worn on pin.
The beneficial effects of the utility model are: simple in construction, low cost, dependable performance, and application is good at the scene；Dimension maintainer holds handle, and driving end is blocked adjusting nut, utilizes the unidirectional intermittent movement adjusting nut elasticity of lever principle and ratchet, thus reaches to adjust the purpose of brake cylinder piston travel；Fully solve narrow space at checking cylinder piston, the problem that common wrench cannot be goed deep into, both protected neighbouring railcar sand pipe and brake head, and crew and dimension maintainer's operation can have been facilitated again, it is ensured that Adjustment effect.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model structural representation；Fig. 2 is top view.
Detailed description of the invention
As shown in accompanying drawing 1,2, this device is by driving end 1, ratchet 2, operating handle 3, adapter 4, bolt 6 and wears pin 5 and constitutes, adapter 4 is clamping plate type, driving end 1 is fixed connecting pin through one and is passed through rivet welding, driving end 1 is fixed on two clamping plate one end of adapter 4, two clamping plate other ends connect one and wear pin 5, wear pin 5 two ends nut 6 and fix；Wearing one ratchet 2 of installation on pin 5, operating handle 3 one end is provided with ratchet, and matches with the ratchet 2 worn on pin 5.
Its work process and principle be: being stuck in fixing for driving end 1 on Traffic control system nut, rotating operation handle 3, utilize the unidirectional intermittent movement principle of lever principle and ratchet 2, power on operation handle 3 is delivered to driving end 1, make driving end 1 can block adjusting nut and drive it to rotate, reach the purpose of clamp nut.
