Multifunctional lifting device for unmanned crane

Abstract

The invention discloses a multifunctional lifting device for an unmanned crane. The multifunctional lifting device comprises a base and a rotary disc; the position, close to the center position, of the top surface of the base is provided with the rotary disc, and the top of the rotary disc is fixedly provided with a supporting frame; the top of the supporting frame is provided with a supporting arm; when the height of an object does not reach the moving condition, a second hydraulic rod in a second hydraulic cylinder is controlled to move towards the outer side, thus, the clamping height of the object is further increased, the object moving height is reached, the object is avoided making contact with an object on the ground, and movable transferring work of the object in different directions is facilitated; the top of an installation seat is provided with a clamping plate, the clamping plate is provided with a through hole, and an insert rod penetrates through the interior of the through hole; the appearance outline of the clamping plate and the interior outline of a clamping groove are the same, so that when the clamping plate at the top of the installation seat is inserted into the clamping groove, the insert rod is inserted into the through hole formed in the clamping plate conveniently, installing work of the installation seat is facilitated, and a special gripper is convenient to replace; and the working efficiency is improved, and the time for maintaining and replacing a traditional gripper is greatly shortened.

Description

technical field [0001] The invention relates to the field of unmanned crane equipment, in particular to a multifunctional lifting device used on an unmanned crane. Background technique [0002] Unmanned cranes are an important basis for improving work efficiency. With the continuous development of social economy, users' requirements for lifting equipment are also increasing, and safety performance and quality issues are the focus of attention. [0003] During the use of the existing lifting device used on unmanned cranes, when lifting objects in different positions, the position of the base needs to be moved again, which is inconvenient to use and cannot adjust the position of the work frame. It is not parallel to the ground, which is inconvenient for the rope reel shaft to take in and put out the rope; during the use of the lifting device used on the existing unmanned crane, the traditional gripper can only hook the object, and cannot grip the tubular object. The scope of ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a multi-functional lifting device used on an unmanned crane to solve the problem that the existing lifting device used on an unmanned crane needs to be moved again when lifting objects in different positions during use. The position of the base is inconvenient to use, and the position of the work frame cannot be adjusted. The bottom surface of the work frame is not parallel to the ground, which is not convenient for the rope reel shaft to take in and release the rope; the lifting device used on the existing unmanned crane is in the During use, traditional grippers can only hook objects, but cannot grip tubular objects, and the scope of application is low; during use, the lifting device used on the existing unmanned crane, when gripping pipe fittings of different specifications and sizes , it is necessary to replace the gripper additionally, the use cost is high, and the replacement of the gripper takes a lot of time, which reduces the work efficiency; the lifting device used on the existing unmanned crane can only be lifted by the hydraulic cylinder on the support arm during use. The clamping height of the object, when the height of the object is not enough, it is easy to touch the object on the ground, which is not convenient for moving and handling the object in different directions; the lifting device used on the existing unmanned crane is in use. When installing, it is difficult to insert the insertion rod into the through hole on the card board, it is not convenient to replace the special gripper, and the maintenance and replacement of the gripper takes a long time
