Abstract
The utility model relates to coal mine machinery technical field, specifically a kind of device of round-link chain anti-kink.Round-link chain distorts knotting phenomenon to existing underground coal mine round-link chain pulling equipment frequent occurrence, and round-link chain is caused to be broken initiation accident.The utility model provides a kind of round-link chain anti-kink device, including revolving body, revolving sleeve, elastic cylindrical pin, multifunctional combination connected nut and washer.Revolving body cylindrical end passes through revolving sleeve end circular hole and couples with washer and multifunctional combination connected nut, is fastened by resilient key, and constituting one can be around the swing mechanism that revolving sleeve rotates freely.The utility model structure is simple, safe and reliable, can rotate automatically when it chain distortion occurs in round-link chain distraction procedure and unlock distortion, effectively prevent chain distortion to knot and causes the accident, to guarantee the requirement of safety in production operation.
Description
Technical field
The utility model relates to a kind of coal mine machinery technical fields, concretely relate to a kind of dress of round-link chain anti-kink
It sets.
Background technique
As round-link chain pulling equipment is widely applied in underground coal mine, round-link chain has become coal mine and often uses pulling equipment.Mesh
Before, the most hauling distance of underground coal mine round-link chain pulling equipment is long, and force unbalance once occurs in distraction procedure, will turn round
Bent knotting phenomenon, while shearing force increased dramatically in chain, when being more than that breaking load will cause chain breakage accident, cause to lead
Draw equipment to stop working, and easily causes safety accident.
Summary of the invention
The purpose of the utility model is to provide a kind of round-link chain anti-kink devices, to solve round-link chain in the traction course of work
The problem of middle force unbalance distortion knots, meets the needs of safety in production, realizes the target of traction chain safe operation.
The technical solution of the utility model is: a kind of round-link chain anti-kink device, including revolving body, revolving sleeve, Elastic Circular
Pin, multifunctional combination connected nut and washer.Revolving body cylindrical end passes through revolving sleeve left end circular hole and couples with multifunctional combination connected nut,
And fastened by elastic cylindrical pin, constituting one can be around the swing mechanism that revolving sleeve rotates freely.Similarly, on the revolving sleeve right side
End also constitutes one can be around the swing mechanism that revolving sleeve rotates freely.
Further, revolving body cylindrical end is provided with external thread structure, and annulus end is provided with connection holes.
Further, revolving sleeve is cylindrical structure, and both ends are provided with circular through hole, and centre is provided with circular trough, circular trough
Upper end is provided with opening, and circular trough lower end is provided with circular through hole.
Further, connection holes cooperation chain ring couples round-link chain.
The advantages of the utility model: 1. being cooperated using revolving body and revolving sleeve, multifunctional combination connected nut and elastic cylindrical pin
The structure of fastening, processing and manufacturing is simple, dismounts easy to maintain.The revolution that revolving body left or right is constituted when 2. round-link chain is twisted together
Mechanism can rotate automatically unlocks kink, without human intervention.
Detailed description of the invention
Fig. 1 is the utility model general illustration；
Fig. 2 is the utility model assembling schematic diagram；
Fig. 3 is the utility model revolving body main view；
Fig. 4 is this practical revolving sleeve cross-sectional view；
Fig. 5 is the utility model multifunctional combination connected nut cross-sectional view；
Fig. 6 is the utility model multifunctional combination connected nut side view.
Specific embodiment
In figure: 1, revolving body, 2, revolving sleeve, 3, elastic cylindrical pin, 4, multifunctional combination connected nut, 5, washer.
From Fig. 1-6 it is found that a kind of round-link chain anti-kink device, including revolving body 1, revolving sleeve 2, elastic cylindrical pin 3, more function
It can coupling nut 4, washer 5.
Revolving body 1 is made of annulus end and cylindrical end, and annulus end is provided with connection holes, and cylindrical end end is external screw thread knot
Structure, root are cylindrical structure, and annulus end connection holes can cooperate with the chain ring of various specifications pattern.Revolving sleeve 2 is symmetrical circle
There is circular through hole at column structure, both ends, and it is mounting gasket 5, more function that intermediate opened round slot, which is provided with opening in the upper end of circular groove,
The position of energy coupling nut 4 and elastic cylindrical pin 3, it is disassembly elastic cylindrical pin 3 that the lower end of circular groove, which is provided with circular through hole,
Outlet.1 cylindrical end of revolving body passes through the left end circular hole of revolving sleeve 2, and washer 5 is covered by 2 middle opening of revolving sleeve in revolving body 1
Cylindrical end, multifunctional combination connected nut 4 are threadedly coupled with revolving body 1 and are fixed with elastic cylindrical pin 3.Revolving body 1 and more after assembling
The composition of function coupling nut 4 is the swing mechanism supported with revolving sleeve 2, and clearance fit between the mechanism and revolving sleeve 2 can be free
Rotation.Similarly, the swing mechanism that can be rotated freely around revolving sleeve 2 is also constituted in 2 right end of revolving sleeve.
The application of the utility model
The utility model links together by chain ring by it with round-link chain and by traction object, forms annulus chain haulage system
System.Force unbalance in the round-link chain trailer system course of work, round-link chain are distorted, and distortion is mobile with chain stress point, when
Distortion is moved at swing mechanism, the rotation of stress side swing mechanism, and the swing mechanism of revolving sleeve and the other side will not rotate with it,
Distortion will unlock herein, eliminate the distortion power in round-link chain, prevent round-link chain distortion from knotting, and guarantee that round-link chain works normally.
It should be appreciated that being above signal by the detailed description that preferred embodiment carries out the technical solution of the utility model
Property and not restrictive.Those skilled in the art can be to implementation on the basis of reading the utility model specification
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these modification or
Replacement, the spirit and scope for the utility model embodiment technical solution that it does not separate the essence of the corresponding technical solution.
