[0002] The elevator traction machine is the power equipment of the elevator, also known as the elevator host. Its function is to convey and transmit power to make the elevator run. It consists of a motor, brake, coupling, reduction box, traction wheel, frame, guide wheel and auxiliary turning handwheel. The guide wheel is generally installed on the frame or the load-bearing beam under the frame. Some turning handwheels are fixed on the motor shaft, and some are usually hung on the nearby wall and then put on the motor shaft when in use.
[0003] When the elevator traction sheave assembly in the prior art is in use, friction will occur between the traction steel rope and the traction sheave, which will cause damage due to long-term friction. When damage occurs, the traction sheave needs to be replaced. When replacing, the traction sheave needs to be disassembled as a whole for replacement, resulting in a high cost of maintenance and replacement. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an elevator traction wheel assembly comprises a traction wheel frame, a mounting groove is provided on one side of the traction wheel frame, the traction wheel frame is movably connected with a traction machine shaft through the mounting groove, the outer sides of the traction machine shaft are respectively fixedly connected with key bars, the inner wall of the mounting groove is provided with a key groove, the outer surface of the traction wheel frame is provided with a screw hole, the outer side of the traction wheel frame is fixedly connected with a traction main wheel, the outer side of the traction main wheel is provided with a mounting opening, the inner side of the mounting opening is threadedly connected with a fixing screw, the outer side of the traction main wheel is fixedly connected with a traction disc on the side away from the mounting opening, and one end of the traction main wheel is provided with a sleeve opening.
[0006] Furthermore, four traction discs are provided, and traction grooves are provided between two of the four traction discs, and three traction grooves are provided.
[0007] Furthermore, the traction main wheel and the traction disk are an integrated structure, and the traction main wheel and the traction disk are both made of alloy material.
[0008] Furthermore, the traction main wheel is fixedly connected to the traction wheel frame via fixing screws and a mounting opening.
[0009] Furthermore, a screw groove is formed at one end of the traction machine shaft, and a fixing nut is threadedly connected to one end of the traction machine shaft through the screw groove.
[0010] Furthermore, the inner diameter of the sleeve is matched with the diameter of the traction wheel frame, and the outer surface of the traction wheel frame is smooth.
[0011] The beneficial effects of the utility model are as follows: through the traction wheel frame, the traction main wheel and the fixing screws, when the elevator traction wheel assembly is used, the staff installs the traction steel rope in the traction groove of the traction disk outside the traction main wheel. When the traction machine drives the traction machine shaft to rotate, the traction wheel frame will drive the traction main wheel to rotate. At this time, the traction steel rope will generate friction with the traction disk and the traction groove. When the traction steel rope is damaged due to long-term friction, the traction steel rope will be unevenly stressed. At this time, the traction wheel needs to be replaced. When the traction wheel is replaced, the work The personnel disassemble the traction steel cable and then remove the fixing screws on the traction main wheel, and then the traction main wheel can be disassembled from the traction wheel frame. Then the sleeve on the new traction main wheel is docked on the traction wheel frame, and the installation port and screw port are aligned. Then the fixing screws are inserted into the installation port and screw port, and the fixing screws are tightened to firmly install the traction main wheel on the traction wheel frame. After installation, only the traction steel cable needs to be installed and it can continue to be used. This structural setting does not require the traction wheel to be replaced as a whole, which can reduce maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See also Figure 1 and Figure 4 The utility model provides a technical solution: an elevator traction wheel assembly includes a traction wheel frame 1, a mounting groove 101 is opened on one side of the traction wheel frame 1, the traction wheel frame 1 is movably connected with a traction machine shaft 7 through the mounting groove 101, the outer sides of the traction machine shaft 7 are respectively fixedly connected with key strips 701, the inner wall of the mounting groove 101 is opened with a key groove 102, the outer surface of the traction wheel frame 1 is opened with a screw hole 103, the outer side of the traction wheel frame 1 is fixedly connected with a traction main wheel 2, the outer side of the traction main wheel 2 is opened with a mounting hole 5, the inner side of the mounting hole 5 is threadedly connected with a fixing screw 6, the outer side of the traction main wheel 2 is fixedly connected with a traction plate 3 on the side away from the mounting hole 5, and one end of the traction main wheel 2 is opened with a sleeve 201.
[0020] Specific implementation: There are four traction discs 3, and traction grooves 4 are provided between the four traction discs 3. There are three traction grooves 4, and the traction grooves 4 prevent the traction rope from moving during operation.
[0021] Specific implementation method: The traction main wheel 2 and the traction plate 3 are an integrated structure. The traction main wheel 2 and the traction plate 3 are both made of alloy materials, which makes the traction wheel more durable and not easy to wear.
[0022] Specific implementation method: The traction main wheel 2 is fixedly connected to the traction wheel frame 1 by fixing screws 6 and mounting openings 5. The traction main wheel 2 is firmly mounted on the traction wheel frame 1 by docking the sleeve opening 201 on the new traction main wheel 2 on the traction wheel frame 1, aligning the mounting openings 5 and screw openings 103, and then inserting the fixing screws 6 into the mounting openings 5 and screw openings 103, and tightening the fixing screws 6. The traction main wheel 2 can be firmly mounted on the traction wheel frame 1, and the traction main wheel 2 and the traction wheel frame 1 can be firmly fixed.
[0023] Specific implementation: A screw groove 702 is formed at one end of the traction machine shaft 7, and a fixing nut 8 is threadedly connected to one end of the traction machine shaft 7 through the screw groove 702. By installing the fixing nut 8 on the traction machine shaft 7, the traction wheel frame 1 can be firmly installed on the traction machine shaft 7.
[0024] Specific implementation method: The inner diameter of the sleeve 201 is matched with the diameter of the traction wheel frame 1, and the outer surface of the traction wheel frame 1 is smooth.

When the traction machine drives the traction machine shaft 7 to rotate, the traction sheave frame 1 will drive the traction main wheel 2 to rotate. At this time, the traction steel rope will produce friction with the traction plate 3 and the traction groove 4. When the traction steel rope is damaged due to long-term friction, the traction steel rope will be unevenly stressed. At this time, the traction sheave needs to be replaced. When replacing the traction sheave, the staff will replace the traction steel rope. The rope is removed, and then the fixing screws 6 on the traction main wheel 2 are removed, and the traction main wheel 2 can be removed from the traction wheel frame 1. However, the sleeve 201 on the new traction main wheel 2 is docked on the traction wheel frame 1, and the installation opening 5 and the screw opening 103 are aligned, and then the fixing screws 6 are inserted into the installation opening 5 and the screw opening 103, and the fixing screws 6 are tightened to firmly install the traction main wheel 2 on the traction wheel frame 1.
