Description
Technical field
The utility model belongs to the technical field of railway truck, is specifically related to a kind of hand brake device being arranged on railway hopper car underframe.
Background technology
Hand brake produces brake action for railway vehicle and prevents that parked vehicle from slipping away when carrying out shunting service, and can the size of its leverage ratio be directly connected to vehicle and park safely on request.Railway hopper car is conventionally used for amplifying manual force multiplying power and hand brake force is delivered on foundation brake rigging with the parking brake lever of movable pulley device with being arranged under vehicle body bottom frame composition at present.The round steel assembly welding that original hand brake pull bar reinforced rib place is 16 mm by 3 diameters forms, and due to physical dimension sudden change, causes this place's stress very concentrated.According to statistics, there is crackle in original hand brake pull bar reinforced rib (i.e. 3 round steel assembly welding places) position with movable pulley device, situation about fractureing accounts for parking brake lever crackle, the fault that fractures 50.9%.
Parking brake lever bracket location is inaccurate, and hand brake can drag after tightening and cause pull bar reinforced rib pull-out bracket, and after hand brake is lax, because there is a step at reinforced rib place, cannot automatically get back on bracket, and bracket is held in the palm on the single round steel of pull bar in utilization.In addition hand brake pull bar reinforced rib and pulley composition weight are larger, and strained condition is bad, and easy holder causes reinforced rib and is in service snapping.Hand brake pull rod chain is long, and braking round pin loss, fracture or lock adjust the reasons such as device inefficacy also can cause reinforced rib pull-out pull bar bracket, and easy holder causes reinforced rib and is in service snapping.Once hand brake pull bar reinforced rib ruptures, comes off, and can hit the surface facilitys such as sleeper or track switch, affects traffic safety.
In practice process, due to the difference of individual strength, add the reasons such as application of force inequality, roughly operation, chain butt welding are of low quality, maloperation, often because chain breakage causes that chain is thrown on track, under wheel, on track switch or surface facility, to traffic safety, bring hidden danger, disturbed normal transportation to produce, should attract great attention.
Parking brake lever bracket is connected with the normal fasteners such as bolt, nut that adopt of its seat, in utilization, the reason such as hopper car vibrations easily makes bolt, nut loosening, easily cause the attaching partss such as bracket and parking brake lever, connection chain to be shed on the surface facilitys such as track switch, affect traffic safety.
Due to the restriction in hopper car space and with the hand brake device of movable pulley device, at most hand brake force is amplified to the restriction of 2 times, along with the transportation development of heavy haul railway hopper car, simple by using and be used for amplifying manual force multiplying power and be delivered to the hand brake force on foundation brake rigging with the parking brake lever of movable pulley device at present, can not meet the requirement of long steep grade safe stopping amplification tonnage railway hopper car.
Because newly-designed railway hopper car generally adopts shorter draw beam, adopt traditional hand braking movable pulley device, and hand brake is when alleviating position, the hand braking chain of movable pulley junction and axletree and wheel tracks are from closer and likely run into axletree or wheel, cause chain friction axle or wheel to affect traffic safety, this causes very large difficulty just to traditional parking brake lever design with movable pulley device, even cannot arrange.
Therefore for meeting the requirement of traffic safety and the structural limitations of vehicle own etc., need to develop a kind of new construction and safe and reliable railway hopper car hand brake device, make it can meet the requirement of using large multiplying power hand brake force in large-tonnage railway hopper car hand brake device, can prevent that again its hand braking chain, parking brake lever, bracket etc. are shed on the surface facilitys such as track switch and prevent the generation of hand braking chain friction axletree or wheel, avoid affecting traffic safety.
Summary of the invention
Technical problem to be solved in the utility model:
Solve the situation that original hand brake pull bar reinforced rib (the i.e. 3 round steel assembly welding places) position with movable pulley device of railway hopper car crackle occurs, fractures, once prevent the fracture of hand brake pull bar reinforced rib, come off, hit sleeper or track switch, affect traffic safety.
Solve the needs that large-tonnage railway hopper car adopts movable pulley device to amplify hand braking multiplying power still to can not meet braking during standstill under mal-condition, and parking brake lever is difficult for the design challenges that cloth deposits in narrow space.
