Prefabricated block safety lifting device

technical field

The utility model relates to the cross technical field of machinery and refractory materials, in particular to a prefabricated block safety lifting device.

Background technique

Compared with building prefabricated blocks, refractory prefabricated blocks have complex shapes, and in order to ensure the performance, there is basically no skeleton structure inside, and the strength is low, so it is easy to be damaged during transportation. In the lifting process of the existing refractory prefabricated parts, for large prefabricated blocks without preset lifting rings, forklift slings are often used to wrap the prefabricated blocks on the prefabricated blocks, and they are carried by forklifts or cranes, or placed on pallets for whole pallet transportation. Although the former method can avoid collisions with other prefabricated blocks during transportation, it requires a forklift or two cranes for auxiliary operations, and is more prone to safety hazards caused by the slipping of the sling; the latter method is often caused by The shaking during forklift transportation will cause damage to the corners of the prefabricated blocks, which is time-consuming and labor-intensive.

In order to achieve the above object, the technical solution of the utility model is:

A prefabricated block safety lifting device, including a suspension ring, the upper part of the suspension ring is a screw rod, and the lower part is a polished rod. The suspension ring is provided with a spiral torsion bar, a movable pin sleeve, and a fixed plate in sequence from top to bottom. The spiral torsion bar and The screw rod part of the lifting ring is connected flexibly, the movable pin sleeve is located at the lower part of the helical torsion bar, and can move up and down along the screw rod, and the fixed plate is sleeved on the periphery of the movable pin sleeve, and can move up and down along the outer circumference of the movable pin sleeve; A movable boom is welded on the movable pin sleeve, and the movable boom is hinged to a 7-shaped movable clamping arm through a connecting pin shaft, and a fixed boom is welded on the fixed plate, and the fixed boom is hinged 7 Glyph fixed clamping arm.

As an improvement to the above technical solution, there are one or two fixed clamping arms, and one or two fixed booms; when the fixed clamping arm and the fixed boom are one, the movable clamp The holding arm is corresponding to the fixed clamping arm, forming an included angle of 180 degrees; when there are two fixed clamping arms and fixed booms, the two fixed clamping arms form an included angle of 90 degrees, and the movable clamping arm The angle between the arm and the two fixed clamping arms is 135 degrees. The clamping arm structure is adopted, one of the clamping arms is a movable clamping arm, which can adapt to a variety of workpieces with different shapes through the change of the relative angle of the movable clamping arm; each clamping arm is detachable, and one of the fixed clamping arms After being dismantled, the angle of the movable clamping arm can be changed into a two-legged clamp, which expands the scope of application.

As an improvement to the above technical solution, the movable clamping arm and the fixed clamping arm are hinged to a clamping plate through a locking shaft. The clamping plate, the movable clamping arm and the fixed clamping arm adopt the pin shaft connection form, which can automatically adapt to the shape of the workpiece.

As an improvement to the above technical solution, a rubber plate is provided on the clamping plate. In this way, the damage of the fixture to the workpiece is reduced.

As an improvement to the above technical solution, the lower part of the suspension ring is provided with a return spring, which is sleeved around the circumference of the suspension ring. In this way, the automatic opening of the clamp is guaranteed, the difficulty of operation is reduced, and manpower is saved.

Compared with the prior art, the beneficial effects of the utility model are:

The prefabricated block safety lifting device of the utility model works in cooperation with the row crane, which can ensure that the refractory prefabricated block is not damaged during the transfer process, and has high safety, and can realize the safe and fast refractory prefabricated block at a lower cost. transport.
