Description

Technical Field

[0001] This utility model belongs to the technical field of hoisting equipment and relates to a self-tightening movable I-beam hoisting auxiliary device. Background Technology

[0002] In many work scenarios such as industrial construction and logistics loading and unloading, hoisting operations are frequently required on structures built with I-beams. Current hoisting methods often have several problems, such as traditional hoisting equipment being insufficiently flexible in its movement on I-beams, inaccurate positioning, or a lack of effective auxiliary stabilizing devices to ensure the safety and stability of the hoisting process. These problems can lead to low hoisting efficiency and even safety accidents, causing personal injury and property damage. Utility Model Content

[0003] The purpose of this utility model is to address the problems existing in the prior art by providing a self-tightening movable I-beam hoisting auxiliary device, which solves the problems that traditional hoisting equipment is not flexible enough in moving on I-beams, is not accurate enough in positioning, or cannot ensure the safety and stability of the hoisting process.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A self-tightening movable I-beam hoisting auxiliary device includes two first hoisting plates arranged in parallel. The first hoisting plates have a second hoisting plate arranged symmetrically to them on their side, and the two are connected by a central axis fixing rod. The first hoisting plate is U-shaped and includes a horizontal part, a vertical part and an inclined part.

[0006] A pulley stop valve is provided between the two horizontally positioned portions of the first hoisting plates, and a pulley assembly is provided below the pulley stop valve;

[0007] The bottom of the first lifting plate is provided with a third lifting plate, and the two are hinged together by a first width adjusting rod. The bottom of the second lifting plate is provided with a fourth lifting plate, and the two are hinged together by a second width adjusting rod. The ends of the third lifting plate and the ends of the fourth lifting plate are hinged together by a lifting rod.

[0008] Furthermore, the second lifting plate is the same in shape and size as the first lifting plate.

[0009] Furthermore, both ends of the central axis fixing rod, both ends of the first width adjusting rod, and both ends of the second width adjusting rod all pass through the two first lifting plates and the two second lifting plates.

[0010] Furthermore, the two ends of the lifting rod pass through two third lifting plates and two fourth lifting plates.

[0011] The beneficial effects of this utility model are as follows:

[0012] During use, this utility model can move flexibly on the I-beam and is accurately positioned, ensuring a safe and stable lifting operation, improving lifting efficiency, and reducing the incidence of safety accidents. Attached Figure Description
