Abstract
The utility model discloses a plate-type chain, which comprises a plurality of chain links, wherein each chain link comprises an outer chain mat, a middle chain mat, an inner chain mat and a pin shaft, pinholes and pin shafts of the middle chain mat of all chain links or partial chain links are tightly engaged and connected, the technical proposal is that the pin holes and the pin shafts of the middle chain mat are tightly engaged and connected, the force is born by the middle chain mat and the outer chain mat, more than half of the load which needs to be initially born by the outer chain mat is reduced, thereby substantially enhancing service life and security of the chain and completely satisfying the special use requirements of stacking machines.
Description
Technical field
The utility model relates to a kind of board-like chain, particularly relates to a kind of board-like chain that is exclusively used in the fork lift truck tool.
Background technique
The chain link of board-like chain comprises inner link and the outer link that is hinged, and inner link is that some inner plates are formed, and outer link comprises two outer plates and some intermediate plates.At present, intermediate plate of the prior art substitutes with inner plate fully, and promptly chain has only outer plate, and inner plate and bearing pin are formed.This kind structure, because inner plate and bearing pin are loose fits, so have only outer plate stressed in the outer link in the time of stressed initial of chain, the intermediate plate on the outer link does not stress.Because the fork lift truck tool plays dynamic load and makes that more greatly bearing load was very big when outer plate was initial, the distortion so the outer plate pin-and-hole is easy to be stretched is added after chain is subjected to certain responsive to axial force, and outer plate and bearing pin come off easily, thereby influence the chain life-span, cause potential safety hazard even accident.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of board-like chain, and intermediate plate in the outer link and outer plate are shared stressed, thereby improves chain life-span and safety in utilization.
To achieve the above object, the utility model has adopted following technological scheme:
A kind of board-like chain is made up of several chain links, and each chain link includes outer plate, intermediate plate, inner plate and bearing pin, and the pin-and-hole of the intermediate plate of all or part of chain link is connected with the bearing pin drive fit.
As preferably, the above-mentioned bearing pin two ends of stating are provided with and the friction tight packing ring of bearing pin.Further avoid distortion of outer plate pin-and-hole and bearing pin to break away from.
As preferably, above-mentioned bearing pin surface is provided with the enhancement process layer.
Above-mentioned bearing pin can be spacing by cubic riveting, also can be spacing by the circle riveting, and can also be spacing by 2 rivetings.
The utility model is owing to adopted above technological scheme, the pin-and-hole of intermediate plate is connected with the bearing pin drive fit, share stressed by intermediate plate and outer plate, make the load that to bear when outer plate is initial reduce more than 1 half, thereby improve the working life and the Security of chain greatly, can adapt to the special usage requirement of fork lift truck tool fully.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
Embodiment 1:
A kind of board-like chain as shown in Figure 1 is made up of several chain links, and each chain link includes outer plate 2, intermediate plate 5, inner plate 1 and bearing pin 3, and the pin-and-hole of the intermediate plate 5 of all or part of chain link is connected with bearing pin 3 drive fits.
Above-mentioned bearing pin 3 two ends are provided with and bearing pin 3 friction tight packing rings 4; Above-mentioned bearing pin 3 surfaces are provided with the enhancement process layer; Above-mentioned bearing pin 3 is spacing by cubic riveting, and bearing pin 3 can also be spacing fixing by circle riveting or 2 rivetings certainly.
Because intermediate plate and bearing pin are friction tight, so in the outer link, outer plate and intermediate plate are shared stressed when initial, make the load that must bear when outer plate is initial reduce more than 1 half, thereby improve the working life and the Security of chain greatly.
