Description

Technical Field

[0001] This utility model relates to the field of lifting and hoisting equipment technology, specifically a bridge cable lifting and hoisting equipment. Background Technology

[0002] A bridge cable crane is a type of lifting equipment that uses flexible steel cables as large-span overhead load-bearing components. It uses a trolley to move back and forth on the load-bearing cable to lift heavy objects. As an important construction equipment in bridge construction, it is widely used in large-scale engineering projects such as water conservancy and hydropower projects, mining, forestry, and bridge construction. It features large span, high flexibility, and strong adaptability.

[0003] When using existing bridge cable lifting equipment, workers use the hooks at the bottom of the equipment in conjunction with wire ropes to lift heavy objects. However, since the hooks at the bottom of the equipment are usually fixed, the equipment cannot effectively adjust the spacing between adjacent hooks according to the size of different heavy objects. This reduces the applicability of the equipment to some extent and is not conducive to the lifting of heavy objects. Utility Model Content

Two guide grooves 7 are symmetrically arranged at the bottom of the mounting shell 1, and a push-pull block 8 is provided above the guide grooves 7. The top of the movable block 5 passes through the guide grooves 7 and is connected to the push-pull block 8. A disc 9 is located at the top of the inner cavity of the machine compartment 2, and a transmission assembly 10 is provided at the top of the disc 9 to adjust the position of the hook assembly 6. By setting the transmission assembly 10, the movable block 5 can slide back and forth along the length direction of the guide groove 7, thereby adjusting the position of the hook assembly 6 at the bottom of the movable block 5. The machine compartment 2 is equipped with a drive assembly 11 that provides rotational force to the disc 9. By setting the drive assembly 11 and cooperating with the transmission assembly 10, the spacing of the hook assembly 6 can be adjusted by the staff according to the actual size of the heavy object, thus improving its applicability. Two strip seats 14 are symmetrically arranged above the mounting shell 1. The bottom of the strip seats 14 is equipped with a lifting assembly 17 for supporting the entire mounting shell 1. Vertical rods 15 are fixedly connected to the top of both ends of the strip seats 14. By setting the lifting assembly 17, the mounting shell 1 can be supported from both ends, which makes the lifting of heavy objects smoother and helps to improve the stability of the lifting operation. The top of the vertical rod 15 is equipped with a traveling assembly 16 to facilitate the lifting operation. By setting the traveling assembly 16, the entire mounting shell 1 can be driven to move back and forth on the carrying cable to achieve the lifting of heavy objects.
