Abstract
The utility model belongs to the technical field of parts of rail wagons and particularly relates to an integrally-forged hand brake pull rod jaw which can be used for solving the problem that the existing hand brake pull rod jaw of the rail wagon is easy to crack and drop so as to influence the driving safety. The integrally-forged hand brake pull rod jaw is integrally forged; one end of the integrally-forged hand brake pull rod jaw is a U-shaped structure which is connected with a movable pulley and the other end of the integrally-forged hand brake pull rod jaw is a straight-plate gradient circular platform structure which is connected with circular steel; a connecting hole is arranged at the center of the structure end of the circular platform in an axis direction and the middle part between the U-shaped structure and the structure end of the circular platform is in a plate-shaped structure; and the top and bottom of the middle part are arc-shaped and grooves are arranged at two sides of the middle part along the length direction. The integrally-forged hand brake pull rod jaw disclosed by the utility model has the beneficial effects that the problems of great welding stress of the hand brake pull rod jaw, welding defects, welding deformation and the like are solved; the integrally-forged hand brake pull rod jaw is convenient to assemble and position and the assembling is convenient, fast and reliable; and the problems that a reinforcing rib part of the original hand brake pull rod jaw provided with a movable pulley device is cracked and broken so as to influence the driving safety are solved.
Description
Technical field
The utility model belongs to the technical field of railway truck with parts, is specifically related to a kind of solid forging hand brake pull rod jaw.
Background technology
Hand brake is used for railway vehicle and when carrying out shunting service, produces brake action and prevent that parked vehicle from slipping away, the size of its leverage ratio be directly connected to vehicle on request safety park.Railway truck is used for amplifying the manual force multiplying power with the hand brake pull bar that drives pulley gear usually and hand brake force is delivered on the foundation brake rigging.The round steel assembly welding that original hand brake pull bar reinforced rib place is 16 mm by 3 diameters forms, because the physical dimension sudden change causes this place's stress very concentrated.According to statistics, crackle takes place in the hand brake pull bar reinforced rib of original drive pulley gear (i.e. 3 round steel assembly welding places) position, situation about fractureing accounts for the parking brake lever crackle, the fault that fractures 50.9%.Because in a single day hand brake pull bar reinforced rib ruptures, comes off, and can hit sleeper or track switch, influences traffic safety.
Like the easy problem that crackle takes place, fracture in hand brake pull bar reinforced rib (the i.e. 3 round steel assembly welding places) position of Fig. 1, drive pulley gear shown in Figure 2; Hand brake pull bar carriage location is inaccurate; After tightening, hand brake can cause the pull bar reinforced rib to pull out carriage, and after hand brake is lax, because of there is a step at the reinforced rib place; Can't get back to automatically on the carriage, carriage is held in the palm in utilization on the single round steel of pull bar.Hand brake pull bar reinforced rib and pulley composition weight is bigger in addition; Strained condition is bad; Be prone to cause reinforced rib to be in service snapping; Hand brake pull bar chain comes off, long, the braking round pin is lost, fracture or lock are transferred the device inefficacy etc., and reason also can cause reinforced rib to pull out the pull bar carriage, is prone to cause reinforced rib to be in service snapping.
Therefore for satisfying requirement such as traffic safety, need to develop a kind of hand brake pull rod jaw of safe and reliable new construction.
Summary of the invention
The utility model ruptures easily, comes off in order to solve existing railway wagon hand brake drawhead, thereby influences the problem of traffic safety, and a kind of solid forging hand brake pull rod jaw is provided.
The utility model adopts following technical scheme to realize:
A kind of solid forging hand brake pull rod jaw; It is characterized in that it is solid forging, the one of which end is and movable pulley bonded assembly U type structure that the other end is and the straight plate gradual change of round steel bonded assembly frustum cone structure; Have connecting bore on the frustum cone structure end central axial direction; Centre portion between U type structure and the frustum cone structure end is a slab structure, and the top of centre portion and bottom are circular shape, centre portion along on its length direction both sides have groove.
Another preferred version of the utility model: the frustum cone structure end is evenly equipped with four elongated slots along its circumferential edge.
The relative prior art of the utility model has following beneficial effect:
1, both artistic and practical, reduced the welding job amount, the position while welding connection and reasonable arrangement has solved that the parking brake lever welding stress is big, problems such as weld defect and welding deformation.
2, be convenient to the assembling location, easy to assembly quick reliable.
3, this device does not influence the function or the requirements such as braking, alleviation and hand braking chain pine surplus, the amplification of movable pulley multiplying power of railway wagon hand brake machine.
Crackle takes place in hand brake pull bar reinforced rib (the i.e. 3 round steel assembly welding places) position that 4, has solved original drive pulley gear, fractureing influences the problem of traffic safety.
5, can cause the pull bar reinforced rib to pull out carriage after having solved hand brake and tightening and cause that the pull bar fracture influences the traffic safety problem.

Among the figure: the 1-movable pulley, the 2-chain guide, 3-solid forging hand brake pull rod jaw, the 4-parking brake lever, 5-staking pin, packing ring, the collar, the hand braking chain of 6-is formed 7-pull bar carriage, 8-reinforced rib, 9-frangible place.
The specific embodiment
Further specify in conjunction with the specific embodiment of accompanying drawing the utility model.
The round steel assembly welding that the pull bar reinforced rib place that adopts the replacement of solid forging hand brake pull rod jaw to use always at present is 16 mm by 3 diameters forms.The first end of solid forging parking brake lever forges into the U type and is connected with movable pulley; The other end forges into straight plate gradual change frustum cone structure and is connected with round steel; Centre portion is than original structure length lengthening 200mm; The left and right sides wide employing concave bar has improved intensity and has alleviated weight simultaneously, and top, bottom two leptoprosopy adopt arc surface to be convenient on hand brake pull rod guide, move and expendable weight in order to reduce with the hand brake pull rod guide area of contact and the power of reducing friction.
U type end forges processing two holes, the back movable pulley the same with original design and connects, and has reduced the welding job amount after this end and the centre portion solid forging, has avoided problems of welded quality, has improved presentation quality.
Frustum cone structure end processing and round steel connecting bore be convenient to lead round steel and location; Make the assembling of parking brake lever round platform head and round steel efficient and convenient and difficult assembling is inclined to one side; Be uniformly distributed with four elongated slots of processing at the round platform end along circumferential edge and be convenient to the plug welding round steel, make weld seam symmetry, reliable, reduce welding stress concentration; Reduce welding deformation, improved presentation quality.
