Description

An engineering loading and unloading fixture

technical field

The utility model relates to the technical field of engineering, in particular to a loading and unloading fixture for engineering.

Background technique

Engineering is the application of science and mathematics by which the properties of matter and energy in nature can be manipulated through structures, machines, products, systems and processes in the shortest time and with the least amount of manpower Something efficient, reliable, and useful to humans. The general term for various disciplines formed by applying the theories of natural science to specific industrial and agricultural production sectors.

Hoisting refers to the general term for the installation and positioning of equipment by a crane or a lifting mechanism. Requirements during the hoisting process: (1) For the rolling method used in earth method construction to load and unload mobile equipment, the thickness of the roller bars should be consistent, and the annual length should be 50cm longer than the width of the supporting row. It is strictly forbidden to fill the roller bars with gloves. When loading and unloading the truck, the slope of the rolling edge shall not be greater than 20°. The raceway shall be set up flat and firm, the joints shall be staggered, and the rolling speed shall not be too fast. A slip rope shall be used if necessary. (2) When the tower tank is hoisted by the rotation method or the knock down method, the hinge installed at the bottom of the tower body must have the ability to resist the horizontal thrust generated during the hoisting process. When it is in place, let it slowly fall into the foundation to avoid accidents and deformation. (3) When installing equipment on a frame or a building, its strength and stability must meet the requirements of the installation conditions. After the equipment is installed and positioned, it must be connected and fastened or welded according to the requirements of the drawings. The decoupling can only be done after the strength and stability of the design requirements are met, otherwise it must be temporarily fixed.

During the construction of existing projects, when it is necessary to lift steel pipes of different diameters, the lifting fixture used in the lifting process can not be clamped conveniently, and the anti-skid property is poor during the clamping process, which affects the safety of lifting.

Utility model content

The purpose of the utility model is to provide a loading and unloading fixture for engineering in order to overcome the deficiencies of the prior art.

The utility model is realized through the following technical solutions:

A loading and unloading fixture for engineering, comprising a lifting frame, the lifting frame is in a circular structure, lifting hooks are arranged on both sides of the lifting frame, and several clamping assemblies are arranged on the circumferential direction of the lifting frame, the The clamping assembly includes a clamping rod, a rotating handle, and a clamping block, the clamping rod and the clamping block are fixedly connected, the clamping block is located inside the connecting sleeve, and the connecting sleeve is connected to the clamping plate , the clamping block is connected with the tension spring, and several anti-skid blocks are arranged on the clamping surface of each clamping plate.

As a preferred technical solution of the utility model, the clamping rod and the rotating handle are fixedly connected.

As a preferred technical solution of the present invention, a wear-resistant layer is provided on the outer surface of the lifting hook.

As a preferred technical solution of the present invention, the anti-slip blocks are evenly distributed on the clamping surface of the clamping plate.

Compared with the existing technology, the beneficial effect of the utility model is: the utility model is simple in structure, by setting the clamping assembly and the wear-resistant layer, so that when working, the steel pipe is set between the lifting brackets, and the rotating handle drives the The clamping rod rotates to realize the clamping plate approaching the surface of the steel pipe and the clamping of the anti-slip block. At this time, the clamping force can be increased under the action of the anti-slip block, the clamping stability is good, and the clamping force is large and durable. The grinding layer can reduce the wear of the lifting ring and prolong the service life.
