Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a rigid boom gantry crane suitable for lifting various materials. Background Technology

[0002] Lifting tools refer to the devices used in lifting machinery to lift heavy objects. The most commonly used lifting tools for lifting packaged goods are hooks and slings; others include lifting rings, lifting suction cups, clamps, and forks. They are widely used in the lifting and hoisting industry.

[0003] There are many types of lifting equipment, and multi-material lifting equipment is one of them. Multi-material lifting equipment requires the use of rigid boom gantry cranes. However, rigid boom gantry cranes cannot adjust the position of the hook during use, which means that the user cannot adjust the distance of the hook according to the size of the material. At the same time, it is not possible to position and tighten the two sides of the top of the material. The lifted items are prone to tilting, which is inconvenient for the user and affects the normal use of the equipment. Utility Model Content

[0037] As a technical optimization of this utility model, by setting the connecting plate 9, the electric telescopic rod 42 can be fixed to prevent the electric telescopic rod 42 from moving up and down when it moves. By setting the electric telescopic rod 42, the pressure plate 43 can be positioned.

[0038] The working principle and usage process of this utility model are as follows: When in use, the user drives the motor 32, which drives the positive and negative threaded rods 33 to rotate. The positive and negative threaded rods 33 drive the threaded sleeves 34 to move closer together. The threaded sleeves 34 drive the positioning blocks 35 to move closer together. The positioning blocks 35 drive the fixed bearings 21 to move closer together. The fixed bearings 21 drive the positioning rods 22 to move closer together. The positioning rods 22 drive the connecting blocks 23 to move closer together. The connecting blocks 23 drive the stabilizing blocks 24 to move closer together. The stabilizing blocks 24 drive the hooks 25 to move closer together, so that the hooks 25 hook the items. Then, the electric telescopic rod 42 is driven, which drives the pressure plate 43 to move downward to press the items tightly, so that the items are tightly attached to the hooks 25. After completion, the lifting device 1 is driven. The lifting device 1 drives the transmission mechanism 3 to move upward through the lifting rope. The transmission mechanism 3 lifts the items through the hook mechanism 2.

[0039] In summary, this rigid boom gantry crane, suitable for lifting various materials, uses a transmission mechanism 3 to control the distance of the hook mechanism 2. The hook mechanism 2 then hooks up the object to be lifted, and the clamping mechanism 4 positions the top of the object on both sides. Users can adjust the hook distance according to the size of the material, and the mechanism also positions and clamps the top of the material on both sides to prevent tilting, thus facilitating user operation and ensuring normal use.
