Although the general structure of the chain is basically similar, the step chain of the escalator is different from the bicycle chain, and the weight of the step chain is not in an order of magnitude, which causes the butt joint of the step chain to be difficult, and one person can not finish the butt joint like the common chain. Through foretell structure to the face that sets up first installation department 11 and second installation department 21 and be close to each other is the rectangle, and rectangle length extends along vertical direction, and when the installation butt joint like this, first installation department 11 and second installation department 21 are close to each other, because mounting hole 8 is slightly greater than the diameter of screw rod 7, under the drive of step chain weight, the upper portion of rectangular surface is preferred to support tight contact, and first installation department 11 and second installation department 21 are constantly close, and two rectangular surfaces are laminated gradually, offset the influence of step chain weight. And the hook part is tightly hooked on the chain link, so that the distance between the two inner chain links is continuously reduced.
The connecting part is obliquely arranged, the lower end of the connecting part is fixedly connected with the upper end of the hook part, and the upper end of the connecting part is fixedly connected with the lower end of the mounting part; the distance between the two hook parts is larger than the distance between the two mounting parts. Two inclined connecting parts are the positions butted towards the chain links, so that the effective design and the use length of the connecting parts and the screw 7 can be reduced, the connecting strength between the tools is ensured, and the material cost is saved.
In the embodiment, the total length of the first mounting part 11 and the screw 7 thereon is greater than the distance between two pin shafts 63 on one outer chain link; the length of the projection of the connecting part to the horizontal plane is greater than the distance between the two sleeves 43 on one inner chain link; the length of the cuboid and the length of the external leakage of the screw 7 are smaller than the distance between the two pin shafts 63 on one external chain link, so that the application range of the tool in the embodiment is wide.
Supplementary butt joint frock in this embodiment through setting up the first installation department 11 of cuboid, with the vertical setting of the rectangular surface of first installation department 11 and second installation department 21, with the thickness of first connecting portion 12 by supreme increase in proper order down, set up arc portion 53 and supporting part 52 to the weight of balanced step chain makes laborsaving, convenient and swift more when step chain docks.
Example 2
As shown in fig. 1 to 6, the method for butting step chains (a first inner chain link 41 and a second inner chain link 42) by using the auxiliary butting tool for escalator step chains in embodiment 1 of the present embodiment specifically includes the following steps:
1) as shown in fig. 1, the first member 1 and the second member 2 are hooked to the bushings 43 of two inner links to be butted, respectively. In the present embodiment, the first hook portion 13 of the first member 1 is hooked on the bushing 43 on the outer side of the first inner link 41, and the second hook portion 23 of the second member 2 is hooked on the bushing 43 on the outer side of the second inner link 42. I.e. the docking method in this embodiment, the hooks hook over two bushings 43 on the outside of the inner link that need to be docked. The hook part of the tool is matched by the arrangement method, so that the inner chain link can rotate by taking the outer sleeve 43 as a rotation point, and the plug pin of the outer chain link can be conveniently inserted in the butt joint process. If the position of the two inner links is fixed, inserting the latch has certain difficulty when the heavy step chain is butted.
2) As shown in fig. 2, the screw 7 of the first mounting portion 11 is inserted into the mounting hole 8 of the second mounting portion 21, and the nut 3 is screwed into the outer periphery of the screw 7, thereby reducing the distance between the two inner links.
3) As shown in fig. 3 and 4, when the distance between the two inner links is reduced to a proper position, the pin 63 of the outer link assembly 61 is inserted into the bushing 43 of the inner link, and then the outer chain sheet 62 is mounted on the pin 63, thereby completing the butt joint of the stepchain.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
