A crane lifting adjustment device

Abstract

The invention discloses a hoisting adjustment device for a crane, which comprises a vibration damping arm, a rotating support arm, a hoisting adjustment arm, a suspension rope limit sleeve, a mounting frame and a rotating fixed frame. The rotating fixed frame is arranged on the mounting frame and rotates The fixed frame is provided with a rotating shaft, and the middle part of the rotating shaft is provided with a connecting arm. Directly below the vibrating arm, the left end of the rotating support arm is fixedly connected to the rotating shaft, a weight detection platform is arranged between the rotating support arm and the vibration damping arm, and a weight sensor is arranged between the weight detection platform and the rotating support arm; the structural design of the present invention Novelty, double protection for the lifting equipment, prevent the cargo from rushing to the top, ensure the safe operation of the lifting work, easy to operate, greatly improve the work efficiency, can fine-tune the position of the hook, and improve the practicability of the device.

Description

technical field [0001] The invention relates to the technical field of crane hoisting, in particular to a crane hoisting adjustment device. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. According to its function and structural characteristics, cranes can be divided into four categories: light and small lifting equipment, bridge type cranes, jib type cranes, and elevators; cranes can reduce labor force and improve operating efficiency, and are widely used in all walks of life , with the development of the lifting industry, people have higher requirements for the safety, adjustability, and lifting capacity of the crane. The bridge crane relies on the lifting trolley to run on the track on the bridge frame to form a rectangular work. When lifting, the adjustment of the position of the hook is completely dependent on the adjustment of the lifting trolley and th...

Problems solved by technology

According to its function and structural characteristics, cranes can be divided into four categories: light and small lifting equipment, bridge type cranes, jib type cranes, and elevators; cranes can reduce labor force and improve operating efficiency, and are widely used in various industries , with the development of the lifting industry, people have higher requirements for the safety, adjustability, and lifting capacity of the crane. The bridge crane relies on the lifting trolley to run on the track on the bridge frame to form a rectangular work. When lifting, the adjustment of the position of the hook is completely dependent on the adjustment of the lifting trolley and the beam. The control accuracy of the lifting trolley is not high, and the operating range is large. It is difficult to control the position of the hook. It is inconvenient to operate when the hook is connected to the cargo. Moreover, it cannot be rotated, and the efficiency of lifting goods is low. When the limit device of the crane fails, it is easy to rush to the top, and there is a certain danger. functions, are prone to failure, and cannot meet the needs of actual use, so there is an urgent need for improved technology in the market to solve the above problems
