Description
Technical field
The utility model relates to freight car braking technical field, is specially a kind of railway wagon hand brake device.
Background technology
Hand brake produces brake action for railway vehicle and slips away to prevent parked vehicle when carrying out shunting service, can the size of its leverage ratio be directly connected to vehicle and park safely on request.Current railway truck usually with being arranged in vehicle body bottom frame composition below, and is used for amplifying manual force multiplying power and being delivered to by hand brake force on the foundation brake rigging of wind braking near the parking brake lever of central sill place band movable pulley device.The round steel assembly welding that original hand brake pull bar reinforced rib place is 16 mm by 3 diameters forms, due to physical dimension sudden change, cause very concentrated situation hand brake pull bar reinforced rib (i.e. 3 round steel assembly welding places) position likely occurring and crackle occurs, fractures of this place's stress, in addition parking brake lever bracket location is inaccurate, hand brake can hold in the palm 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 return on bracket, bracket is held in the palm on the single round steel of pull bar in utilization.In addition to form weight comparatively large for hand brake pull bar reinforced rib and pulley, and strained condition is bad, and easily holder causes reinforced rib place and is in operation and snaps.Hand brake pull rod chain is long, and braking round pin is lost, fracture or lock adjust the reasons such as device inefficacy that reinforced rib also can be caused to pull out pull bar bracket, and easily holder causes reinforced rib place and is in operation and snaps.Hand brake pull bar reinforced rib once fracture, come off, the surface facility such as sleeper or track switch can be hit, affect traffic safety.
Due to the restriction of rail wagon base frame underlying space and at most hand brake force to be amplified the restriction of 2 times with traditional hand brake device of movable pulley device, along with the transportation development of heavy duty goods train, simple by using the parking brake lever of band movable pulley device to be used for amplifying manual force multiplying power at present and being delivered to the hand brake force on wind braking foundation brake rigging, can not meet the requirement that long steep grade safe stopping amplifies tonnage railway truck.
Because newly-designed railway truck generally adopts shorter draw beam, adopt traditional hand braking movable pulley device, and hand brake be in alleviate position time, then 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, affect traffic safety, this causes very large difficulty just to the design of the parking brake lever of traditional band movable pulley device, even cannot arrange.
The parking brake lever device of traditional band movable pulley is adopted mainly to be arranged on below rail wagon base frame near central sill place, and this place next-door neighbour bogie truck, cause narrow space, operator comes in and goes out difficulty, thus to assembling, to check and maintenance parking brake lever device is made troubles.
In addition narrow gage railway roller bearing adapter stabilizer bar and its vehicle body bottom frame lower space compact, cannot by the hand brake device scheme of conventional belt movable pulley during hand brake device design.
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 wagon hand brake device, make it can meet the requirement using large multiplying power hand brake force in narrow gage railway lorry, large-tonnage railway wagon hand brake device, its parking brake lever, bracket etc. can be prevented again to be shed on the surface facilitys such as track switch and to prevent the generation of hand braking chain friction axletree or wheel, avoid affecting traffic safety, and assembling and maintenance facility.
