Description

Pneumatic anti roll device

Technical field

The utility model relates to a kind of automobile-used pneumatic anti roll device of mine motor, a kind of locomotive is related in particular on slope It spends on biggish track when running, prevents the pneumatic anti roll device of locomotive runaway.

Background technique

Anti roll device is that one kind prevents locomotive in parking on ramp or operational process, because of operator's maloperation or braking Failure of apparatus etc. causes vehicle along the emergency stop (apparatus) of the downward runaway in ramp.

Currently, the anti-slip measure that mining electric locomotive uses mainly has anti-slip metal shoe, manually anti-slip hook and generally pneumatically prevents Car slipping device.Anti-slip metal shoe needs staff to operate under vehicle, and runaway measure is prevented when only stopping, can not be timely and effectively It operates in an emergency situation；Anti- hook of sauntering needs driver to be manually operated manually, if driver cannot react in time or mechanism blockage, then Best braking opportunity is easily missed, locomotive runaway can not be effectively prevented；General pneumatic anti roll device is pushed away using cylinder by connecting rod The working method of anti-slip hitch decline is moved, the reaction time is longer, and it is more demanding to cylinder, it is easy to appear and prevents sauntering what hook fell automatically Failure, and while working, damages cylinder larger, needs to change cylinder substantially using after primary.

Utility model content

For the problems in the relevant technologies, the utility model proposes pneumatic anti roll devices, can fast and effeciently prevent machine The slipping accident of vehicle in an emergency situation；The anti roll device for substituting manual operation, prevents from slipping caused by manual operation not in time Vehicle accident；From the damage eliminated in principle in anti roll device work to cylinder.

In order to achieve the above technical purposes, technical scheme of the utility model is as follows:

Pneumatic anti roll device, including prevent hook of sauntering, hanger plate, the hanger plate are vertically and fixedly provided in the middle part of the anti-hook of sauntering Two guide hole plates disposed in parallel are equipped in one end far from anti-hook of sauntering, two guide hole plates are equipped with lead along the vertical direction Xiang Kong, passing through in two pilot holes has pin shaft I, and one end of the pin shaft I is equipped with nut, and the pin shaft I passes through hanger plate On gap, one end of the guide hole plate is fixed on the car body, and the top of the pin shaft I is equipped with single-acting cylinder, the list Active cylinder is located on hinge seat, and the pin shaft I passes through the hole of hinge seat, and the lower end of the hanger plate is connected with by pin shaft II Otic placode, the single-acting cylinder, otic placode are fixedly connected with the vehicle body.

Further, the single-acting cylinder is connected with two-bit triplet and pulls reversal valve.

Further, the single-acting cylinder is single-acting spring reset cylinder.

Further, the hanger plate is fixed by welding in anti-saunter on hook.

Further, the aperture of the hinge seat is greater than pilot hole aperture.

The utility model has the beneficial effects that improving, existing pneumatic anti roll device is high to cylinder requirement, and cylinder is easy to damage Defect, substantially without replacement cylinder, reduce maintenance cost；Anti- hook of sauntering is swift in motion flexibly, instead of traditional people Power control mode when driver being allowed to find car slipping trend, puts down anti-hook of sauntering at the first time, prevents the deterioration of accident, ensure property and Personal safety.
