Abstract
The invention discloses a lifting tool for a large steel ingot and a large forge piece. The lifting tool for the large steel ingot and the large forge piece comprises two clamp arms and two clamp claws, wherein the lower end parts of the two clamp arms are fixedly connected with the two clamp claws respectively; the middle parts of the two clamp arms are hinged through a pin shaft; a cover plate is installed on the pin shaft; and the two clamp claws are matched to clamp the large steel ingot and the large forge piece. The lifting tool for the large steel ingot and the large forge piece is simple in structure, convenient to install and detach and non-hazardous in operation, is applicable for lifting the large steel ingot and the large forge piece, can be operated only by a crane operator, without needing other auxiliary workers, thus saving manpower to a certain extent, is strong in practicality, can improve the productivity, reduce the labor intensity and the operating dangerousness of working staff, meets lifting requirements of the large steel ingot and the large forge piece, and achieves safe and reliable lifting work; the workpiece clamping principle of the lifting tool for the large steel ingot and the large forge piece is different from that of an ordinary lifting tool, and a clamping force is generated by self weight of a workpiece, so that the lifting tool meets requirements on structural strength and rigidity, has good clamping performance and is material-saving.
Description
Technical field
The present invention relates to the suspender field, refer to especially a kind of suspender for large-scale steel ingot and forging.
Background technology
Flourish along with China's industrial construction, the equipment of the departments such as metallurgy, machinery, electric power, oil, chemical industry shipbuilding, aviation, defense Industry and some light industry is all to large capacity, high-power, performance-oriented future development, weight and dimensional characteristic to product are increasing, and the heavy forging (abbreviation heavy forging) that occurs therefrom manufacturing is the heavy-duty machinery Base of manufacture.Heavy forging has the distinguishing features such as the large body weight of shape, production is wide in variety, requirements for quality is high.In the process that Large Steel iron enterprise produces, the handling of large-scale steel ingot and forging products is that one very heavy and to have a handling of work, especially high-temperature forging of certain danger very dangerous.
At present, usually adopt a large amount of riggings that large-scale steel ingot and forging are carried out handling, operating personal must be near workpiece in the handling process, danger is higher, and also to be subject to the thermal radiation of high temperature during high-temperature forging in loading and unloading, virtually increased especially operator's labour intensity and the danger of operation.The automatic tongs load-carrying capacity that uses now is too little, operates too slowly, can not satisfy the lifting job of large-scale steel ingot and forging fully.
Summary of the invention
Technical matters to be solved by this invention is: a kind of suspender for large-scale steel ingot and forging is provided, and this hanger structure is simple, easy to loading and unloading, and operation can be widely used in large-scale steel ingot and forging without dangerous.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of suspender for large-scale steel ingot and forging, comprise two tong arms and two chelas, captive joint with two chelas respectively in the bottom of described two tong arms, the middle part of two tong arms is hinged by bearing pin, on the described bearing pin cover plate is installed, two chelas cooperate clamping large-scale steel ingot and forging.
As a kind of preferred scheme, the upper end of two tong arms all is equipped with bearing pin.
As a kind of preferred scheme, be equipped with on the described chela and be convenient to the clamping work pieces slit.
As a kind of preferred scheme, described chela is U-shaped.
As a kind of preferred scheme, the material of described tong arm and chela is dead-soft steel.
After having adopted technique scheme, effect of the present invention is: a kind of suspender for large-scale steel ingot and forging, comprise two tong arms and two chelas, captive joint with two chelas respectively in the bottom of described two tong arms, the middle part of two tong arms is hinged by bearing pin, on the described bearing pin cover plate is installed, two chelas cooperate clamping large-scale steel ingot and forging.This hanger structure is simple, easy to loading and unloading, operation is applicable to the handling of large-scale steel ingot and forging without dangerous, and the worker that only need drive a vehicle just can attach operation, need not other auxiliary workers, saved to a certain extent manpower, this suspender is practical, not only can boost productivity, alleviate the danger of labor strength and operation, also satisfied the handling requirement of large-scale steel ingot and forging simultaneously, realized safely and reliably lifting job.In addition, the principle of this suspender holding workpiece is different with general suspender, and its gripping power results from the deadweight of workpiece, and structural strength, rigidity requirement had both been satisfied in this design, possessed again good gripping performance and materials and economized.
The material of described tong arm and chela is dead-soft steel, and it generally can to produce joint plasticity and the impact toughness of serious sclerotic tissue or quenching structure and postwelding not good because of welding, excellent weldability.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the embodiment of the invention;
In the accompanying drawing: 1. tong arm; 2. chela; 3. the first bearing pin; 4. the second bearing pin; 5. the 3rd bearing pin.
The specific embodiment
Below by specific embodiment a kind of suspender for large-scale steel ingot and forging of the present invention is described in further detail.
As shown in Figure 1, comprise two tong arms 1 and two chelas 2, two tong arms, 1 middle part is hinged by the first bearing pin 3, captive joint with two chelas 2 respectively in the bottom of described two tong arms 1, the upper end of two tong arms all is equipped with bearing pin, be respectively the second bearing pin 4 and the 3rd bearing pin 5, cover plate all is installed on the described bearing pin, two chelas 2 cooperate clamping large-scale steel ingot and forging.
Preferably, be equipped with on the described chela 2 and be convenient to the clamping work pieces slit, in the present embodiment, described chela 2 is U-shaped, and the material of described tong arm 1 and chela 2 is dead-soft steel.
During handling, twine secondary chain in the bottom of two tong arms 1, the upper end of two tong arms 1 is hinged with main chain by the second bearing pin 4 and the 3rd bearing pin 5 respectively, the bottom that secondary chain upwards draws two tong arms 1, so that staying open state, two chelas 2 shift to large-scale steel ingot and forging, after arriving assigned address, slowly put down this suspender, after chela 2 lands, chela 2 clamps large-scale steel ingot and forging when the main chain lifting is closed, and handling is slowly put down suspender to assigned address, the driving worker so that chela 2 is opened, unloads secondary chain lifting with workpiece.In the handling process, do not need auxiliary worker that workpiece is operated, the labour intensity that has greatly alleviated the operative employee has also reduced danger simultaneously.
Because the principle of this suspender holding workpiece is different with general suspender, its gripping power results from the deadweight of workpiece, and structural strength, rigidity requirement had both been satisfied in this design, possessed again good gripping performance and materials and economized.
