Description
Technical Field
The utility model relates to a lifting appliance for heat treatment of a pull rod of a heavy screw press, which can be widely applied to the heavy screw press.
Background
The existing heavy screw press has the defects that the weight of a pull rod is large, the volume is large, the conventional lifting appliance of a steel wire rope is simply used in the heat treatment process of the pull rod, the lifting is unstable, a workpiece is easy to fall off, the personal safety of personnel in a field workshop is seriously endangered, and even the personal casualty safety accident occurs.
Disclosure of Invention
The utility model aims to provide the heavy screw press pull rod heat treatment lifting sling which has the advantages of simple structure, convenience in operation, easiness in lifting, reliability in clamping, stability in operation and strong safety, ensures the product quality after one-time heat treatment of workpieces, and improves the production efficiency.
In order to achieve the purpose, the lifting sling for heat treatment of the pull rod of the heavy screw press comprises a lifting cross beam, wherein a plurality of lifting holes are formed in the center of the lifting cross beam, the lifting cross beam is symmetrically arranged at two ends of the lifting cross beam, a pair of lifting upper arms are hinged with the lifting cross beam through hinge shafts, the lifting upper arms are respectively hinged with each lifting upper arm through hinge shafts, two clamping type lifting lower arms which are clamp-shaped are formed together, and the clamping type lifting lower arms are used for lifting the pull rod and are respectively hinged with connecting plates of the lower arms through hinge shafts.
The utility model relates to a lifting appliance for heat treatment of a pull rod of a heavy screw press, which has the working principle that: when the heat treatment of the lifting pull rod works, the steel wire rope passes through the lifting hole to be hung on the crane hook, and the pull rod is hung on the pair of clamp type lifting lower arms. Then, when the crane lifts the pull rod from the ground, downward pulling force is formed due to the weight of the pull rod, and under the action of the pulling force, the pair of lifting upper arms move inwards and transversely through the hinge point. Finally, through the hinge joint of the lifting upper arm and the clamp type lifting lower arm, the lifting upper arm pushes the pair of clamp type lifting lower arms, and the pair of clamp type lifting lower arms rotate around the inner sides of the respective hinge axes on the connecting plate respectively, so that the pull rod workpiece is clamped, and the pull rod workpiece is placed into heat treatment equipment to be subjected to heat treatment.
According to the lifting sling for heat treatment of the pull rod of the heavy screw press, disclosed by the utility model, the workpiece is lifted and put down, an operator is not required to closely contact the lifting sling and the heated height Wen Lagan, the safety risk of the operation of the worker is avoided, the heat radiation injury of the operator is avoided, the potential safety hazard is thoroughly eliminated, and the safety is strong.
The lifting appliance for heat treatment of the pull rod of the heavy-duty screw press has the advantages of simple structure, convenient operation, easy lifting, reliable clamping, uniform stress of the pull rod and stable operation. The heat treatment of the workpiece can be completed rapidly, so that the operation time of the heat treatment of the workpiece is shortened obviously, the product quality after one-time heat treatment of the workpiece is ensured, and the production efficiency is improved. In conclusion, the lifting sling for heat treatment of the pull rod of the heavy screw press has the advantages of simple structure, convenience in operation, easiness in lifting, reliability in clamping, stability in operation and high safety, ensures the quality of products after heat treatment of one workpiece, and improves the production efficiency.
Drawings
The utility model will be further described with reference to the accompanying drawings and examples.
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a left side view of fig. 1.
Detailed Description
In fig. 1 and 2, the lifting sling for heat treatment of a pull rod of a heavy screw press comprises a lifting beam 1, wherein a plurality of lifting holes a are formed in the center part of the lifting beam, a pair of lifting upper arms 2 are symmetrically arranged at two ends of the lifting beam and are hinged with the lifting beam through hinge shafts, the lifting upper arms are respectively hinged with each lifting upper arm through hinge shafts, two clamping type lifting lower arms 3 which are used for lifting the pull rod 5 are formed in a clamp shape together, and connecting plates 4 are respectively hinged with each lower arm through hinge shafts 6.
The present utility model is not limited to the above-mentioned embodiments, but is intended to be limited to the above-mentioned embodiments, and any simple modification, equivalent substitutions and improvements made in the above-mentioned embodiments, without departing from the scope of the present utility model, will fall within the scope of the present utility model.
