Abstract
The utility model discloses a lifting appliance for a large-size steel ingot and a forge piece. The lifting appliance comprises two tong arms and two tong claws, wherein the lower ends of the two tong arms are respectively and fixedly connected with the two tong claws; the middle parts of the two tong arms are hinged through a pin shaft; the pin shaft is provided with a cover plate; and the two tong claws are matched to clamp the large-size steel ingot and the forge piece. The lifting appliance is simple in structure, convenient to assemble and dissemble and safe to operate, and is suitable for hoisting of large-size steel ingots and force pieces; and the lifting appliance can be operated by a crane driver, and other auxiliary workers are not needed, so that the manual labor is saved to a certain extent. The lifting appliance is strong in practicability, can not only improve the productivity, lessen the labor intensity and reduce the operation dangerousness, but also meet the hoisting requirement of the large-size stele ingots and the forge pieces, and safe and reliable hoisting operation is realized. Besides, the principle of the lifting appliance for clamping workpieces is different from those of ordinary lifting appliances, and the clamp force comes from the dead load of the workpieces. With the adoption of the design, the structural strength and rigid requirement are met, favorable clamp performance is realized, and materials can be saved.
Description
Technical field
The utility model relates to the suspender field, refers 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 to carry out handling to large-scale steel ingot and forging, 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 when the loading and unloading high-temperature forging, 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.
The utility model content
Technical problem to be solved in the utility model 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, the technical solution of the utility model 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 described bearing pin, cover plate is installed, two chelas coordinate 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 described chela and be convenient to the clamping work pieces gap.
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 utility model 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 described bearing pin, cover plate is installed, two chelas coordinate 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 work of only need driving a vehicle just can be attached operation, need not other auxiliary works, 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 lifting job safely and reliably.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
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model embodiment;
In 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 utility model is described in further detail.
As shown in Figure 1, comprise two tong arms 1 and two chelas 2, two tong arm 1 middle parts are 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 described bearing pin, two chelas 2 coordinate clamping large-scale steel ingot and forging.
Preferably, be equipped with on described chela 2 and be convenient to the clamping work pieces gap, 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, bottom at two tong arms 1 is wound around secondary chain, 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, make two chelas 2 stay open state and 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 work makes chela 2 open secondary chain lifting, and workpiece is unloaded.In the handling process, do not need auxiliary work 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.
