Technical Field
[0001] The utility model relates to a transmission frame, in particular to a novel transmission frame for a construction hoist. Background Art
[0002] The transmission frame is a key component for the operation of a construction hoist, used to install a transmission mechanism. The transmission mechanism drives the gear rack to rotate, raising or lowering the cage for vertical lifting, ensuring the smooth operation of the hoist on the standard section.
[0003] As Figure 1 shown, the conventional products on the current market are all composed of a frame and a transmission main board, which cannot ensure the force on the pulley group. This method cannot ensure the uniform force on the pulleys of the transmission frame. Therefore, there is an urgent need for a novel transmission frame for a construction hoist to solve the above problems. Content of the Utility Model
[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a novel transmission frame for a construction hoist, which is composed of a frame, a pulley group, a transmission main board, a mounting plate, and an ear plate. The frame is the basic structure, the transmission main board is used to install the power device, the mounting plate is used to install the anti-falling device and the limiter, and the pulley group is attached to the main chord of the standard section, solving the problems in the prior art that the pulleys and the standard section are severely worn, and some pulleys are in unilateral contact and stressed, resulting in greater wear, and it is convenient to maintain the main chord of the pulley and the standard section. It is applied to the connection and assembly of the standard section of a manned construction hoist, improving the operation stability of the hoist.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a novel transmission frame for a construction hoist, comprising: a frame, a pulley group mounted on the frame, a transmission main board, a mounting plate, and an ear plate. The mounting plate is arranged at the end of the transmission main board, the ear plate is mounted above the frame, and the pulley group is mounted below the frame.
[0006] Furthermore, the frame includes: cross beams and columns, and two cross beams and two columns are spliced into a complete rectangular frame.
[0007] Furthermore, the mounting plate and the transmission main board are arranged in the hollow part of the rectangular frame.
[0008] Furthermore, the mounting plate is provided with mounting holes for installing the anti-falling and limiting devices.
[0009] Furthermore, the transmission main board is provided with mounting holes for the power device.
[0010] Furthermore, there are two ear plates, symmetrically arranged on the upper cross beam.
[0011] Further, two sets of pulley blocks are provided, symmetrically arranged on the lower cross beam, connected to the standard section, and guiding the lifting cage to move up and down.
[0012] The beneficial effects of the present utility model are as follows: it solves the problem that the coaxiality between the transmission mechanism and the mounting plate is not high, resulting in uneven stress on the pulleys. Compared with the existing transmission mechanism type, the overall structure has high stability, increases the coaxiality between the transmission mechanism and the mounting plate, reduces the uneven stress on the pulleys, and improves the operation stability of the elevator.
