Description

Technical Field

[0001] This utility model relates to a drive component, and more particularly to a lift drive component. Background Technology

[0002] The lift drive assembly is used to install the lift belt rollers, shafts, and drive motor for easy maintenance of the locking pins. Existing lift drive assemblies are generally double-rail frame structures welded from two specifications of channel steel, one specification of angle steel, one specification of square tubing, and various types of steel plates. For example... Figure 1 As shown, the main frame 1 consists of two parallel channel steels. The motor mounting plate 4 and the roller bearing mounting plate 6 are installed between the two channel steels, and the maintenance pin mounting plate 8 is installed on one of the channel steels. Not only is the structure relatively complex and the volume large, but installation and maintenance are also extremely inconvenient. Therefore, it is necessary to improve the existing elevator drive assembly. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a lifting platform drive assembly that not only reduces the types of profiles and the size and volume, but also has a more compact structure and is easier to install and maintain.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a lifting platform drive assembly, including a main frame, a motor mounting plate, a roller bearing mounting plate, and a maintenance pin mounting plate. The main frame is a main beam structure made of a single H-beam. The motor mounting plate is directly mounted on the upper part of the H-beam and is equipped with a motor adjustment screw mounting plate. The roller bearing mounting plate is fixed to the upper part of the H-beam by roller bearing mounting square tubes, and bearing seat adjustment screw mounting plates are symmetrically arranged at both ends of the roller bearing mounting plate. The maintenance pin mounting plate is fixed to one side of the H-beam by a maintenance pin mounting beam.

[0005] Furthermore, a first supporting steel plate is provided on one side of the motor mounting plate and the H-beam, and a second supporting steel plate is provided on one side of the maintenance pin mounting beam and the H-beam. The first supporting steel plate, the second supporting steel plate, and the H-beam are welded together to form a skeleton beam structure.

[0006] Furthermore, there are four motor adjustment screw mounting plates, distributed at the four corners of the motor mounting plate.

[0007] Furthermore, the maintenance pin mounting beam is a square tube.

[0008] Furthermore, there are four maintenance pin mounting plates, symmetrically distributed at both ends of the square tube.

[0009] Compared with the prior art, this utility model has the following advantages: The lifting drive assembly provided by this utility model is a frame beam structure welded from one specification of H-beams, one specification of square tubing, and various steel plates. The updated structure requires two fewer types of profiles, reducing the types of materials used. The overall dimensions are smaller, the structure is more compact, and the weight is reduced by 15% after the frame modification. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Figure 2 This is a schematic diagram of the elevator drive assembly structure of this utility model.

[0016] Please see Figure 2 The lifting platform drive assembly provided by this utility model includes a main frame 1, a motor mounting plate 4, a roller bearing mounting plate 6, and a maintenance pin mounting plate 8. The main frame 1 is a main beam structure made of a single H-beam. The motor mounting plate 4 is directly mounted on the upper part of the H-beam and is provided with a motor adjusting screw mounting plate 3. The roller bearing mounting plate 6 is fixed to the upper part of the H-beam through a roller bearing mounting square tube 2. Bearing seat adjusting screw mounting plates 5 are symmetrically arranged at both ends of the roller bearing mounting plate 6. The maintenance pin mounting plate 8 is fixed to one side of the H-beam through a maintenance pin mounting beam 7.

[0017] The lifting drive assembly provided by this utility model has a first supporting steel plate 9 provided on one side of the motor mounting plate 4 and the H-beam, and a second supporting steel plate 10 provided on one side of the maintenance pin mounting beam 7 and the H-beam. The first supporting steel plate 9, the second supporting steel plate 10 and the H-beam are welded together to form a skeleton beam structure, which further improves the overall strength and stability.

[0018] The lifting platform drive assembly provided by this utility model includes four motor adjusting screw mounting plates 3, distributed at the four corners of the motor mounting plate 4. The maintenance pin mounting beam 7 is a square tube, and four maintenance pin mounting plates 8 are symmetrically distributed at both ends of the square tube. In use, the drive motor 11 and the lifting belt roller 12 are... Figure 3 As shown, it is mounted on top of the structure, which is very compact and easy to install and maintain.

[0019] In summary, the lifting platform drive assembly provided by this utility model is constructed from one type of H-beam, one type of square tube, and various steel plates welded into a frame beam structure. The updated structure requires two fewer types of profiles, reducing the number of material types. The overall dimensions are reduced, the structure is more compact, and the weight is reduced by 15% after the frame modification.
