Abstract
The utility model provides a kind of lifting device of coupler, comprise two tong arms and by articulated section hinged for two tong arms, it is characterized in that: the end of described two tong arms is provided with through hole, is provided with shackle in described through hole, connected by steel rope between two described shackles; Described two tong arm front ends are all provided with arc steel plate, and two described arc steel plates are arranged mouth to mouth, form holding part.This lifting device structure is simple, clamping is firm, can reduce labor intensity and improve labor safety guarantee.
Description
Technical field
The utility model belongs to the dismantling technology field of machine parts, is specifically related to a kind of lifting device for dismounting couplers.
Background technology
In overhaul of the equipments operation process, it is a conventional overhauling project that coupler is changed, change in the upkeep operation of coupler, due to the smoother of coupler own, do not concentrate on work at selected units, again unusual weight, coupler is installed after usually boiling heating by temperature booster or oil, so often all more difficult when changing coupler, maintenance worker usually wears mitten and installs, the danger that existence is scalded and weight falls.
Utility model content
The utility model is for defect of the prior art, and provide a kind of lifting device coupler can stablized clamping and sling, it can reduce labor intensity and improve labor safety guarantee.
The technical solution of the utility model is: a kind of lifting device of coupler, it is characterized in that: comprise two tong arms and by articulated section hinged for two tong arms, the end of described two tong arms is provided with through hole, in described through hole, shackle is installed, is connected by steel rope between two described shackles; Described two tong arm front ends are all provided with arc steel plate, and two described arc steel plates are arranged mouth to mouth, form holding part.
Tong arm leading portion between described junction and tong arm front end is arc.
For increasing friction force, this lifting device is clamped more firm, inside described arc steel plate, polishing is frosting or fixedly mounts brake shoe inside arc steel plate.
Described holding part outer upper and bottom are respectively installed with a spring.
The lifting device of a kind of coupler of the present utility model, holding part is stuck in coupler outside, is exerted a force to steel rope by lift system, makes holding part clamp coupling, and carries out dismantling or installation exercise.At upper and lower two springs of the arranged outside of holding part, when using lifting device, by Inner end for entrance blocks coupler, and spring can prevent coupler from skidding off from outside.Lifting device of the present utility model also can be used in the tubular machines such as bearing and unload in the lifting operation of accessory.
Accompanying drawing explanation
fig. 1the structural representation of the lifting device of a kind of coupler of the present utility model;
fig. 2a kind of holding part structural representation of embodiment.
Specific embodiment
The utility model is described further by embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of lifting device of coupler, comprise two tong arms, 1, two tong arms in articulated section 2 by bolted splice, tong arm is divided into tong arm leading portion 6 and tong arm back segment by articulated section 2, and tong arm front end 6 is arc.
Tong arm 1 end has through hole 3, and be provided with shackle 4, two shackles 4 in through hole 3 and connected by steel rope 5, steel rope 5 is force application parts of lift system.
As shown in Figure 2, the front end of tong arm 1 is provided with arc steel plate 7, and two arc steel plates 7 are arranged mouth to mouth, form holding part, be bolted inside arc steel plate 7 and be provided with brake shoe 8, the outside of two arc steel plates 7, upper and lower respectively fixedly mounts a spring 9.
During use, be entrance clamping coupler by the holding part Inner side of non-mounting spring 9, lift system forces in steel rope 5, and on steel rope 5, power upwards makes brake shoe 8 clamp coupler, and the existence of spring 9 makes bearing or coupler not easily skid off outside holding part.
