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, they are widely used in industry and warehousing. Traditional lifting platforms typically use a motor and a screw drive to directly achieve the lifting function.

[0003] When the lifting platform stays at a certain height, especially when performing 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 faults will occur, reducing the service life of the lifting platform's screw rod and affecting the lifting platform's 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

[0007] The step block drive device is located on both sides of the jacking guide lower base, which is used to realize the lifting and supporting functions of the bracket on the lifting platform;

[0008] The jacking guide lower base is located directly below the bracket on the lifting platform and is used to realize the jacking and guiding functions of the bracket on the lifting platform;

[0009] The bracket on the lifting platform provides an assembly platform for realizing automatic lifting of multiple fixed heights.

The end of the lead screw close to the middle position is connected to the output end of the second commutator through a coupling, and the servo motor is connected to the input end of the first commutator through a coupling. The output end of the first commutator is connected to the input end of the two second commutators through a coupling and a transmission shaft.

[0012] The step block is welded from multiple support steel pipes of different heights, support panels, sensor mounting plates, and support bottom plates. By placing the bracket on the lifting platform on support panels of different heights, the height positioning function of the lifting platform is achieved;

[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.

[0016] The jacking and guiding lower base can realize the synchronous lifting of two screw lifts through an ordinary motor, which is used to realize the jacking 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 installed on the corresponding guide rail mounting columns, and the four guide rail mounting columns are 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.

[0020] Furthermore, the four lifting legs of the lifting platform are located at the four corners of the work surface and are used to support the work surface; the lifting bracket is used to connect the lifting legs horizontally to ensure the stability of the lifting platform.

[0021] Compared with the existing technology, the significant progress of the present invention is: 1) The present invention uses a screw lift to synchronously lift the heavy-load assembly platform, and uses support panels of different heights on the step blocks to perform positioning and support by horizontally moving the step blocks. The structure is novel and ingenious.
