Abstract

The utility model relates to a connecting device between rail wagon workpieces, which is characterized by comprising a bolt, a sleeve and a nut, wherein a screw rod of the bolt sequentially penetrates through bolt holes on a workpiece I and a workpiece II; the head part of the bolt is leaned against the workpiece I; the sleeve sequentially penetrates through the bolt holes on the workpiece II and the workpiece I so as to be sleeved on the periphery of the screw rod of the bolt; one end of the sleeve is leaned against the head part of the bolt; the other end of the sleeve is provided with a circle of boss; the boss is leaned against the workpiece II; and the nut is used for tightly screwing up the screw rod of the bolt from one side of the workpiece II. The connecting device between the rail wagon workpieces has a simple structure, is convenient to disassemble, cannot damage parts when in replacement, is also applied to parts for tightly connecting, has strong universality, and can be widely used for connecting multiple parts of various products.

Description

Connection set between a kind of railway freight-car workpiece
Technical field
The utility model relates to a kind of connection set, particularly about the connection set between a kind of railway freight-car workpiece.
Background technique
Between the dead lever fulcrum of railway goods train bogie and the dead lever fulcrum seat; Between truck dead lever, floating lever and the brake beam strut; All adopt special-purpose staking pin to be connected between truck dead lever, floating lever and the middle lower link; Between master cylinder front and back lever and brake shoe and the upper connecting rod, between auxiliary lever and the master cylinder rear fulcrum seat; Also all can adopt staking pin Placement between the positions such as hand braking pulley, static pulley.Though above-mentioned staking pin Placement can produce good anticreep effect; But because staking is installed, is dismantled and use inspection inconvenient; Even when dismounting maybe the cut wound mother metal with burning, therefore, needing that development is a kind of can be more easy to operate and use; And keep original anticreep effect, guarantee that railway freight-car builds the connection set of quality.
Summary of the invention
To the problems referred to above, the purpose of the utility model provides a kind of easy to operate, and good anti-drop effect can guarantee that railway freight-car builds the connection set between the railway freight-car workpiece of quality.
For realizing above-mentioned purpose, the utility model is taked following technological scheme: the connection set between a kind of railway freight-car workpiece is characterized in that: it comprises bolt, sleeve and nut; The screw rod of said bolt passes the bolt hole on workpiece one and the workpiece two successively, and the head of said bolt leans on said workpiece one; Said sleeve passes the screw rod periphery that said workpiece two and the bolt hole on the workpiece one are set in said bolt successively, and an end of said sleeve leans the head at said bolt, and the other end is provided with a circle boss, and said boss leans on said workpiece two; Said nut is tightened the screw rod of said bolt from a side of said workpiece two.
The utility model is owing to take above technological scheme, and it has the following advantages: 1, the utility model comprises bolt, sleeve and nut, when operation, penetrates the bolt hole on the workpiece with bolt earlier; Penetrate sleeve from the other end then, and make it, at last through the nut screwing clamping bolt over against the bolt head relevant position; The utility model can be used for the parts that multiple vehicle need connect, and is like being connected between brake lever and the truck dead lever, easy for installation; Connect reliably, and have self-locking, anticreep effect.Can only change sleeve when 2, the utility model is changed, all the other not wear-out part under situation in good condition, can continue to use.3, the utility model is applicable to the connection of two workpiece but need connect tight (gapped) and wants to be equally applicable to close-connected component, highly versatile under the situation of reliable (can not get loose).The utility model is simple in structure, be convenient to loading and unloading, do not injure part during replacing, and highly versatile can be widely used in the connection of railway freight-car multi-section position.
Description of drawings
Fig. 1 is the utility model structural representation
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is carried out detailed description.
As shown in Figure 1, the utility model comprises bolt 1, sleeve 2 and nut 3.The screw rod of bolt 1 passes the bolt hole on workpiece 1 and the workpiece 25 successively, and the head of bolt 1 leans on workpiece 1; Sleeve 2 passes the screw rod periphery that workpiece 25 and the bolt hole on the workpiece 1 are set in bolt 1 successively, and an end of sleeve 2 leans the head at bolt 1, and the other end is provided with a circle boss 6, and boss 6 is stuck on the workpiece 25; Nut 3 is from tight a bolt 1 screw rod of a side of workpiece 25.
The Placement of the utility model: penetrate the bolt hole on two workpiece with bolt 1 earlier during operation, penetrate sleeve 2 then from the other end, and make its head over against bolt 1; Tight a bolt 1 through nut 3 at last; The utility model can be used for the parts that multiple vehicle need connect, and is like being connected between brake lever and the truck dead lever, easy for installation; Connect reliably, and have self-locking, anticreep effect.
The utility model is applicable to the connection of two workpiece but need connect tight (gapped) and wants to be equally applicable to close-connected component under the situation of reliable (can not get loose).The utility model can only be changed sleeve when changing, all the other not wear-out part under situation in good condition, can continue to use.
Above-mentioned each embodiment only is used to explain the utility model; Wherein the structure of each parts, Placement etc. all can change to some extent; Every equivalents of on the basis of the utility model technological scheme, carrying out and improvement all should not got rid of outside the protection domain of the utility model.
