Abstract
The utility model discloses a forklift leaf chain accessory which comprises an accessory body. A boss is arranged in the middle of the inner side of the accessory body in the overall length direction of the accessory body. A groove is formed in the middle of the outer side of the accessory body in the overall length direction of the accessory body. Pin holes are formed in the two ends of the accessory body in the length direction of the accessory body. The forklift leaf chain accessory made of polyformaldehyde plastic is installed between two outer chain plate sheets arranged at the two sides of each chain link, and can have the guiding function and avoid the phenomenon that due to the fact that a chain plate or a hinge pin collides with a forklift accessory, each chain is damaged in the process of running.
Description
Technical field
The utility model relates to leaf chain, relates in particular to the fork truck leaf chain.
Background technology
Conventional fork truck leaf chain is in operational process in the market, and carrier bar or bearing pin easily shock occur and damage with forklift accessory.
The utility model content
Technical problem to be solved in the utility model just is to provide a kind of fork truck leaf chain annex, after using on the fork truck leaf chain, can prevent chain at motion process intermediate plate or bearing pin and forklift accessory generation shock and damage.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of fork truck leaf chain annex, comprise attachment body, described attachment body middle inside is provided with a boss along the whole length direction of attachment body, the outer middle side part of described attachment body is provided with a groove along the whole length direction of attachment body, and described attachment body length direction two ends are provided with pin-and-hole.
Preferably, described boss is convexly curved.
Preferably, the upper and lower dual-side profile in described groove middle part is the camber line to the groove central concave, and the upper and lower dual-side profile in described groove length direction two ends is the camber line swelled to the upper and lower both sides of groove respectively.
Preferably, described fork truck leaf chain annex is the acetal plastic integrated formed structure.
Acetal plastic annex of the present utility model is arranged between two pin link plate sheets of every pitch chain bar both sides, and its effect with advantage is:
1. interval 7mm between two pin link plate sheets, improved the stability of chain framework;
2. due to bearing pin and pin link plate sheet interference faying face, must increase, the extrusion pressure of bearing pin and pin link plate (joint fastness) has increased by one times thereupon, avoids causing bearing pin and pin link plate to relatively rotate because extrusion pressure is not enough and causes the chain inefficacy;
3. guaranteed that chain board is relative with the gap between inner plate fixing, avoided causing the chain static strength to reduce because gap changes.
4. this acetal plastic annex, can play directional tagging and can prevent again chain at motion process intermediate plate or bearing pin and forklift accessory generation shock and damage.
In a word, the utility model has greatly improved the safe application performance of chain, thereby has also guaranteed the safety of fork truck after using on the fork truck leaf chain.
