It consists of a motor, a brake, a coupling, a speed reducer, a traction wheel, a machine frame, a guide wheel, and an attached handwheel for turning the disk, etc. The guide wheel is generally installed on the machine frame or the load-bearing beam under the machine frame. The handwheel for turning the disk is either fixed on the motor shaft or usually hung on the nearby wall and then sleeved on the motor shaft when in use;

[0003] During the long-term use of the traction rope, a certain amount of dust and sludge will adhere to the surface of the traction rope, and it is easy to accumulate over time. Generally, it needs to be manually cleaned once every half month, which is rather troublesome;

[0004] Moreover, the wire rope works for a long time, is relatively dry, and the wear is relatively large. It not only causes relatively large wear to the rope, but also causes relatively large wear to the wire rope groove. The wire ropes are of different thicknesses, which will lead to uneven force on the ropes. Summary of the Invention

[0032] Embodiment 2:

[0033] As Figures 2 - 7As shown in the figure, the difference between this embodiment and Embodiment 1 is that a protection mechanism 100 is provided between the base 5 and the traction wheel 7. The protection mechanism 100 includes a mounting plate 101, mounting holes 102, an oil storage tank 103, a connecting pipe 104, an oil storage cavity 105, and a protection component 106. Mounting plates 101 are fixedly connected to the outer surface of the upper end of the base 5 on both sides of the traction wheel 7, and mounting holes 102 are opened at positions corresponding to the traction ropes on the outer surface of the upper end of the mounting plate 101. One end of the traction rope passes through the corresponding mounting hole 102. An oil storage tank 103 is provided between the two mounting holes 102, and the oil storage tank 103 is located on one side of the traction wheel 7. Connecting pipes 104 are fixedly communicated with the outer surfaces of both sides of the oil storage tank 103 near the bottom end, and an oil storage cavity 105 is opened at a position near the top end inside the mounting plate 101. The end of the connecting pipe 104 away from the oil storage tank 103 is fixedly connected to the mounting plate 101, and the connecting pipe 104 is communicated with the oil storage cavity 105. A protection component 106 is arranged inside the mounting hole 102. During the operation of the traction machine, the staff can regularly control the protection component 106 to clean the traction rope.

[0034] The protection component 106 includes a first arc-shaped block 107, a cavity 108, a through hole 109, an oil-absorbing cotton 110, a sleeve 111, a first movable groove 112, a first diversion pipe 113, and a mounting ring 114. Two groups of first arc-shaped blocks 107 are symmetrically arranged at positions near the top end inside the mounting hole 102, and a cavity 108 is opened inside the first arc-shaped block 107. A through hole 109 is opened on one side of the inner surface of the cavity 108. The inner surface of the through hole 109 communicates with the inner surface of the first arc-shaped block 107, and an oil-absorbing cotton 110 is fixedly connected inside the through hole 109 in an embedded manner. One end of the oil-absorbing cotton 110 penetrates into the cavity 108, and the other end penetrates outside the first arc-shaped block 107 and is fixedly connected to the first arc-shaped block 107. A sleeve 111 is fixedly connected to the outer surface of one side of the first arc-shaped block 107, and the inner surface of the sleeve 111 communicates with the inner surface of the cavity 108. A first movable groove 112 is opened at a position corresponding to the sleeve 111 on the inner surface of the mounting hole 102, and a first diversion pipe 113 is fixedly connected inside the first movable groove 112. One end of the sleeve 111 penetrates into the first movable groove 112 and is movably connected thereto, and a mounting ring 114 is fixedly connected to the end of the outer surface of the sleeve 111 located inside the first movable groove 112. The first diversion pipe 113 penetrates into the sleeve 111, and the outer surface of the first diversion pipe 113 is tightly attached to the inner surface of the sleeve 111. A connecting plate 119 is fixedly connected to the outer surface of the lower end of each group of first arc-shaped blocks 107, and an electromagnet 120 is arranged on one side of the outer surface of the connecting plate 119. An electromagnet 121 is arranged at a position corresponding to the electromagnet 120 on the inner surface of the mounting hole 102, and the electromagnet 120 and the electromagnet 121 correspond to each other;

[0035] The electromagnet one 120 and the electromagnet two 121 on the upward movement side of the traction rope operate simultaneously, and their magnetic properties are the same. Under the action of the magnetic repulsive force between the electromagnet one 120 and the electromagnet two 121 on its surface, the connecting plate 119 drives the arc-shaped block one 107 and the arc-shaped block two 122 to move towards the traction rope until the oil-absorbing cotton 110 is in close contact with the traction rope;

[0036] A connecting column 115 is fixedly connected to the inner surface of the sleeve 111, and a connecting rod 116 is fixedly connected to the outer surface of the connecting column 115 on the side close to the flow guide pipe one 113. One end of the connecting rod 116 is fixedly connected to the connecting column 115, and the other end is fixedly connected to a piston one 117. The outer surface of the piston one 117 is in close contact with the inner surface of the flow guide pipe one 113. The upper outer surface of the flow guide pipe one 113, away from the sleeve 111, is fixedly connected to a flow guide pipe two 118. One end of the flow guide pipe two 118 is fixedly communicated with the flow guide pipe one 113, and the other end is fixedly communicated with the oil storage cavity 105;

[0037] During the process of the arc-shaped block one 107 approaching the traction rope, the piston one 117 is separated from the flow guide pipe one 113. Therefore, the maintenance oil inside the oil storage cavity 105 enters the inside of the cavity 108 through the flow guide pipe one 113 to infiltrate the oil-absorbing cotton 110. The traction rope passes through the oil-absorbing cotton 110, and the oil-absorbing cotton 110 applies the maintenance oil to its surface for maintenance. The oil-absorbing cotton 110 and the cleaning brush 123 on the upward movement side of the traction rope are not in contact with the traction rope, so as to automatically apply the maintenance oil to the traction rope for maintenance, reduce its wear during operation, extend its service life, and ensure the safety of the elevator operation. When the traction rope is cleaned up, the magnetic properties of the electromagnet one 120 and the electromagnet two 121 are adjusted so that their magnetic properties are opposite. Therefore, under the action of the magnetic adsorption force of the electromagnet one 120 and the electromagnet two 121, the connecting plate 119 drives the corresponding two groups of arc-shaped blocks one 107 and the arc-shaped block two 122 to move away from each other, and the piston one 117 blocks the flow guide pipe one 113 again to prevent waste of the maintenance oil.

[0038] Embodiment Three:

[0039] As Figures 3 - 7As shown in the figure, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that one end of the connecting plate 119 is fixedly connected to the first arc-shaped block 107, and the other end is fixedly connected to the second arc-shaped block 122. The inner surface of each group of second arc-shaped blocks 122 is fixedly connected with a cleaning brush 123. Under the action of the magnetic repulsive force between the first electromagnet 120 and the second electromagnet 121 on the surface of the connecting plate 119, the connecting plate 119 drives the first arc-shaped block 107 and the second arc-shaped block 122 to move towards the traction rope until the cleaning brush 123 and the oil-absorbing cotton 110 are in close contact with the traction rope. During the upward movement of the traction rope, the cleaning brush 123 cleans the dust and sludge on its surface. Some stains directly fall off, and some stains adhere to the surface of the cleaning brush 123. Moreover, an activity cavity 124 is opened inside the second arc-shaped block 122, and a hollowed-out plate 125 is fixedly connected in an embedded manner at a position corresponding to the cleaning brush 123 on the inner surface of the activity cavity 124. One side outer surface of the second arc-shaped block 122 is fixedly connected with a communicating pipe 126, and the inner surface of the communicating pipe 126 is communicated with the inner surface of the activity cavity 124. An activity groove two 127 is opened at a position corresponding to the communicating pipe 126 on the inner surface of the mounting hole 102, and a fixing column 128 is fixedly connected to the inner surface of the activity groove two 127. The communicating pipe 126 penetrates into the interior of the activity groove two 127 and is movably connected therewith, and one end of the fixing column 128 penetrates into the interior of the communicating pipe 126 and is fixedly connected with a second piston 129. The outer surface of the second piston 129 is in close contact with the inner surface of the communicating pipe 126. After the cleaning is completed, the magnetism of the first electromagnet 120 and the second electromagnet 121 is adjusted to make their magnetisms opposite. During the process of the second arc-shaped block 122 moving away from the traction rope, the communicating pipe 126 and the second piston 129 move relative to each other, so that the gas inside the communicating pipe 126 and the activity cavity 124 is blown towards the surface of the cleaning brush 123 through the hollowed-out plate 125, causing the stains attached to its surface to fall off. Therefore, during the process of cleaning the traction rope, self-cleaning of the cleaning brush 123 can be realized.

[0040] The working principle of the present invention: During the operation of the traction machine, the motor 81 drives the power assembly 8 and the transmission assembly 9 to drive the traction wheel 7 to rotate. The traction rope reciprocates under the action of the traction wheel 7. During this process, when the staff can regularly control the protection assembly 106 to clean the traction rope;

[0041] During the cleaning process, the electromagnet one 120 and the electromagnet two 121 on the upward movement side of the traction rope operate simultaneously, and their magnetic properties are the same. Under the action of the magnetic repulsive force between the electromagnet one 120 and the electromagnet two 121 on its surface, the connecting plate 119 drives the arc block one 107 and the arc block two 122 to move towards the traction rope until the cleaning brush 123 and the oil-absorbing cotton 110 are in close contact with the traction rope. And during the process of the arc block one 107 approaching the traction rope, the piston one 117 is separated from the diversion pipe one 113. Therefore, the maintenance oil inside the oil storage cavity 105 enters the inside of the cavity 108 through the diversion pipe one 113 to soak the oil-absorbing cotton 110. When the traction rope moves upward, the cleaning brush 123 cleans the dust and sludge on its surface. Part of the stains directly fall off, and the other part of the stains adheres to the surface of the cleaning brush 123. After the cleaning of the traction rope is completed, it passes through the oil-absorbing cotton 110, and the oil-absorbing cotton 110 smears the maintenance oil on its surface to maintain it. The oil-absorbing cotton 110 and the cleaning brush 123 on the upward movement side of the traction rope are not in contact with the traction rope. Therefore, after cleaning the surface of the traction rope, it can be automatically smeared with maintenance oil for maintenance, reducing its wear during operation, extending its service life, and ensuring the safety of elevator operation;

[0042] After the cleaning of the traction rope is completed, adjust the magnetic properties of the electromagnet one 120 and the electromagnet two 121 so that their magnetic properties are opposite. Therefore, under the action of the magnetic adsorption force between the electromagnet one 120 and the electromagnet two 121, the connecting plate 119 drives the corresponding two groups of arc blocks one 107 and the arc block two 122 to move away from each other. The piston one 117 blocks the diversion pipe one 113 again to prevent waste of maintenance oil. And during the process of the arc block two 122 moving away from the traction rope, the connecting pipe 126 and the piston two 129 move relative to each other, so that the gas inside the connecting pipe 126 and the movable cavity 124 blows towards the surface of the cleaning brush 123 through the hollow plate 125, causing the stains attached to its surface to fall off. Therefore, during the cleaning process of the traction rope, self-cleaning of the cleaning brush 123 can be realized.
