Description

Technical Field

[0001] The invention belongs to the technical field of lifting platforms, and in particular relates to a stepped heavy-load lifting assembly platform. Background Art

[0002] Lifting platforms play a vital role in logistics, production lines and other scenarios; as a common material handling equipment, lifting platforms have been widely used in the fields of industry and warehousing. Traditional lifting platforms usually directly realize the lifting function through motors and screw drives.

[0003] When the lifting platform stays at a certain height, especially when carrying out heavy-load assembly operations for a long time, the lifting platform's screw rod needs to bear a large load at all times. Over time, fatigue damage, bending deformation and other fault phenomena will occur, which reduces the service life of the lifting platform's screw rod and affects the lifting platform's use stability and positioning accuracy.

[0004] With the development needs of the heavy-load automated assembly industry, there is an urgent need for a lifting platform with strong load-bearing capacity, high stability and low failure rate to meet the needs of the heavy-load automated assembly market. Summary of the invention

[0012] The step block is welded by multiple supporting steel pipes, supporting panels, sensor mounting plates and supporting bottom plates of different heights. The height positioning function of the lifting platform is realized by placing the bracket on the lifting platform on the supporting panels of different heights.

[0013] The step block drive device uses a low-power servo motor to make the four step blocks move horizontally synchronously, which is used to realize the lifting and supporting functions of the bracket on the lifting platform. Multiple proximity sensors are used to detect and feedback the moving positions of the four step blocks in real time, ensuring the safety of the lifting platform.

[0014] Furthermore, the lifting guide lower base includes a linear slider mounting seat, a linear slider, a lifting mounting frame, a screw lift, a coupling, a commutator, a transmission shaft, and a motor;

[0016] The lifting and guiding lower base can realize the synchronous lifting of two screw lifts through an ordinary motor, which is used to realize the lifting and guiding functions of the bracket on the lifting platform.

[0017] Furthermore, the bracket on the lifting platform includes a linear slide rail, a slide rail mounting column, and a lifting platform, and the lifting platform is welded by four lifting legs, a lifting bracket, and a work surface;

[0018] The four linear guide rails are respectively installed on the corresponding guide rail mounting columns, and the four guide rail mounting columns are respectively installed on the lifting platform;

[0019] The bracket on the lifting platform is automatically placed on the support surface of the step block corresponding to the height of the step block driving device, realizing automatic lifting of multiple fixed heights.
