Description
Technical field
The utility model belongs to the technical field of railway truck stop mechanism, is specifically related to a kind of railway wagon hand brake chain anti-drop device.
Background technology
The manpower hand brake is one of chief component of Vehicular brake device, and it mainly acts on is to prevent to take place when vehicle from parking separately runaway.Along with the continuous development of China railways lorry up-to-date technology, it mainly is NSW type hand brake that China newly makes railway truck manual braking machine, and this type hand brake has adopted the bigger gear of power output to add chain structure, and this structure chain than before is laborsaving around shaft type.But; In the practice process, because the difference of individual strength, add reasons such as application of force inequality, operation roughly, chain butt welding are of low quality, maloperation; Often because of chain fracture causes that chain is thrown on the track, under the wheel, on track switch or the surface facility; Bring hidden danger to traffic safety, disturbed normal transportation-production, should attract great attention.Therefore for satisfying the requirement of traffic safety, need a kind of hand brake chain that both made of exploitation to rupture, also can not be thrown to the hand brake chain anti-drop device that causes railway operation safety on the track by the fracture chain that hangs.
Summary of the invention
The utility model provides a kind of railway wagon hand brake chain anti-drop device for the chain fracture that solves existing railway wagon hand brake machine can be thrown on the track, under the wheel, on track switch or the surface facility, and bring the problem of hidden danger to railway operation safety.
The utility model adopts following technical scheme to realize:
A kind of railway wagon hand brake chain anti-drop device; It is characterized in that comprising the vertical anticreep seat of hand braking relatively chain that the end carriage fixed pulley seat place of railway truck is provided with; Having on the anticreep seat can be through the hole of hand braking chain; Hand braking chain between anticreep seat top and the hand brake is provided with chain anticreep clamp to be formed, and the below of the fixed pulley that hand braking chain strides across is provided with the chain saddle, and the chain saddle is installed on the fixed pulley seat; Between movable pulley that hand braking chain strides across and the fixed pulley chain bracket is set, the below of the hand braking chain between movable pulley and the fixed pulley is located in the bottom of chain bracket.
Another preferred version of the utility model: described chain anticreep clamp is formed the chain anticreep clamp of the C shape structure that comprises two similar shapes, and two chain anticreep clamps stack in opposite directions, through four groups of bolt and nut connections.
Another preferred version of the utility model: the holder that described chain bracket comprises U-shaped with and the bearer carrier at top, bearer carrier is fixed on the railway truck draw beam.
The utlity model has following beneficial effect:
1, thoroughly solves the current rail lorry and generally do not installed hand braking chain anti-drop device additional; If when railway truck chain fracture in the middle of operation; Possibly make sagging too much chain be thrown to the problem that can cause traffic safety on track or the surface facility; Satisfied the requirement of railway truck traffic safety
Drop hand brake chain hung in problems such as axletrees when the chain bracket that 2, installs additional had solved driving simultaneously.

Among the figure: the 1-hand brake, the hand braking chain of 2-, 3-chain anticreep clamp is formed, 4-anticreep seat, the 5-fixed pulley, 6-chain saddle, the 7-chain bracket, the 8-movable pulley,
3.1-chain link, the 3.2-bolt, the 3.3-flat gasket, the 3.4-spring washer, the 3.5-nut, 3.6-chain anticreep clamp,
7.1-bearer carrier, the 7.2-holder.
The specific embodiment
Railway wagon hand brake chain anti-drop device comprises anticreep seat, chain anticreep clamp composition, chain saddle and chain bracket.
1, adds an anticreep seat at end carriage fixed pulley seat place, an appropriate bore is set on the anticreep seat lets chain pass through.On chain below the hand brake, install chain anticreep clamp additional and form, install position that chain anticreep clamp forms on the chain additional should be above the anticreep seat and between the hand brake, and do not influence the mitigation capability of hand brake, and consider the loose surplus of chain.It is that 3mmC shape anticreep clamp, four bolts, nut, packing rings are formed that the anticreep clamp is made up of two duplicate thickness; Grooved bore on the anticreep clamp; Be convenient to block chain link; Two circular holes and two slotted holes are arranged on the anticreep clamp, guarantee two anticreep clamps after reach two side direction chain links chuckings up and down, use bolt, nut, packing ring fastening again.After forming, the anticreep clamp do not influence the function of chain.Adopt the same anticreep clamp of structure to be convenient to anticreep clamp composition and be stuck in maintenance level attitude balance on the chain.
When chain when the anticreep clamp is formed the top fracture, chain is sagging to be dropped down onto the anticreep clamp and forms and be stuck on the anticreep seat, makes (this distance can not make chain get rid of in orbit) after the sagging certain safety distance of fracture chain, no longer down drops.
2, below fixed pulley, add the chain saddle.
When chain ruptured between anticreep seat and chain saddle, sagging the dropping down onto of chain dropped on the chain saddle, made after the sagging certain safety distance of fracture chain, no longer down dropped.
3, between movable pulley and fixed pulley, add chain bracket.
When the fracture of chain follow-up pulley top, sagging the dropping down onto of chain dropped on the chain bracket, makes after the sagging certain safety distance of fracture chain, no longer down drops.
When chain ruptured below fixed pulley chain saddle and movable pulley, sagging the dropping down onto of chain dropped on chain saddle or the chain bracket, and the sagging distance of fracture chain can not be thrown on the track, influenced traffic safety.
4, anticreep seat, chain saddle, chain bracket all can be assembled, paint with car body in advance; Chain anticreep clamp is formed and can under car, be made and paint; After car load assembling and paint are accomplished, need not move electric welding etc. and influence the technology of car load paint assembles; And with four bolts, nut, packing ring two chain anticreep clamps are assembled on the suitable chain, at last bolt head is pressed from both sides flatly, preventing that the anticreep clamp from coming off or losing influences its function.
