Description

Technical Field

[0001] The invention relates to the technical field of traction wheel auxiliary devices, and in particular to a traction wheel disassembly tool. Background Art

[0002] The elevator traction machine is the power equipment of the elevator, also known as the elevator main machine. Its function is to transport and transmit power to make the elevator run. It is composed of an electric motor, brake, coupling, reduction box, traction wheel, frame and guide wheel and an auxiliary handwheel. The traction sheave is the rope pulley on the traction machine, also known as the traction rope sheave or drive rope sheave. It is a device for transmitting traction power of the elevator. There are multiple rope grooves at intervals on the arc-shaped outer wall of the traction wheel. The traction sheave uses the friction between the traction wire rope and the rope grooves on the traction wheel to transmit power.

[0003] When disassembling and replacing the traction sheave of an existing elevator traction machine, a disassembly tool is usually used to assist in the disassembly. An existing traction sheave disassembly tool consists of a top plate, a hydraulic jack and multiple traction sheaves. The hydraulic jack is detachably connected to the top plate, and each traction sheave is connected to the top plate by a connecting rod. The traction sheave and the top plate are respectively arranged at both ends of the connecting rod. When disassembling the traction sheave, the operator connects the traction sheave to the top plate through the cooperation of the traction sheave and the connecting rod, and then drives the output end of the hydraulic jack fixed on the top plate to extend and press against the wheel barrel. The output end of the hydraulic jack extends, thereby driving the top plate, the connecting rod and the traction sheave to move in a direction away from the traction machine, so that the traction sheave is separated from the traction machine.

[0004] However, in the above-mentioned traction wheel disassembly process, since the installation of the traction plate, top plate, connecting rod and hydraulic jack all rely on the traction wheel and are heavy and large in size, and the weight of the traction wheel itself is also large, multiple operators are required to cooperate in the operation, which makes the operation of the traction wheel disassembly process more cumbersome and time-consuming.

[0032] Reference Figure 1 and Figure 3, a positioning assembly 5 is provided on the circumference of the fixed plate 2, and the positioning assembly 5 includes a positioning collar 51, a connecting plate 52 and a plug-in connector 53. In this embodiment, three connecting plates 52 and plug-in connectors 53 are provided and correspond to each other. The plug-in connector 53 includes a fixedly connected plug-in portion 531 and a pick-up portion 532. The positioning collar 51 is rotatably sleeved on the wheel barrel of the traction wheel 17, and the three connecting plates 52 are fixedly mounted on the side wall of the positioning collar 51 away from the traction wheel 17, and the connecting plate 52 is arranged along the axial direction of the positioning collar 51. The plug-in portion 531 is arranged through the end of the connecting plate 52 away from the positioning collar 51 and is slidably connected to the connecting plate 52. The pick-up portion 532 is fixedly connected to the end of the plug-in portion 531 away from the fixed plate 2. A plug-in hole 11 is provided on the circumferential side wall of the fixed plate 2, and one end of the plug-in portion 531 is inserted into the plug-in hole 11.

[0033] Reference Figure 1 and Figure 3 Before placing the top block 1 and the fixing plate 2, the operator inserts the multiple plug-in parts 531 into the corresponding plug-in holes 11, so that the positions of the fixing plate 2 and the positioning collar 51 remain relatively fixed. The operator sleeves the positioning collar 51 onto the wheel barrel of the traction sheave 17, and rotates the positioning collar 51, so that the top block 1 and the fixing plate 2 rotate to the set position, and the operator rotates the connecting bolt 4, so that the connecting bolt 4 is threadedly fixedly connected to the traction sheave 17.

[0034] Reference Figure 4 and Figure 5 Each connecting bolt 4 is provided with a connection guarantee mechanism, which includes an anti-loosening component 12, and the anti-loosening component 12 includes an anti-loosening washer 121 and a connecting spring 122. The anti-loosening washer 121 is movably sleeved on the circumferential periphery of the rod of the connecting bolt 4. An annular groove 15 is provided on the side of the anti-loosening washer 121 facing the head of the connecting bolt 4. One end of the connecting spring 122 is fixedly connected to the loosening washer and the connection point is located in the annular groove 15. The other end of the connecting spring 122 is fixedly connected to the head of the connecting bolt 4, and the connecting spring 122 is sleeved on the circumferential periphery of the rod of the connecting bolt 4.

[0035] Reference Figure 4 and Figure 5 The connection guarantee mechanism also includes a non-return component 13, which includes a non-return ratchet 131 and a non-return pawl 132. An installation ring groove 14 is circumferentially provided at one end of the rod portion of the connecting bolt 4 close to the head. The non-return ratchet 131 is fixedly installed in the installation ring groove 14, and the non-return pawl 132 is hinged on the circumferential inner wall of the anti-loosening washer 121.

[0036] Reference Figure 1 and Figure 4When the operator rotates the connecting bolt 4, the connecting spring 122 is gradually forced to shrink into the annular groove 15 until the head of the connecting bolt 4 is tightly pressed against the anti-loosening washer 121, which helps prevent the connection between the connecting bolt 4 and the traction wheel 17 from loosening, thereby helping to improve the connection stability between the connecting bolt 4 and the traction wheel 17. After the head of the connecting bolt 4 is tightly pressed against the anti-loosening washer 121, the anti-reverse ratchet 131 and the anti-reverse pawl 132 will bite each other, thereby helping to prevent the reverse rotation of the connecting bolt 4, thereby helping to further improve the connection stability between the connecting bolt 4 and the traction wheel 17.

[0037] Reference Figure 1 and Figure 2 A driving assembly 6 is commonly provided on the fixed plate 2 and the top block 1, and the driving assembly 6 includes a threaded rod 61, a handwheel 62 and an abutment block 63. The threaded rod 61 penetrates the fixed plate 2 and the top block 1 and is threadedly connected to the fixed plate 2 and the top block 1. The handwheel 62 is fixedly mounted on one end of the threaded rod 61, and the handwheel 62 is located on the side of the fixed plate 2 away from the top block 1. The abutment block 63 is rotatably mounted on the end of the threaded rod 61 away from the handwheel 62. A placement groove 7 is provided on the side of the top block 1 away from the fixed plate 2, and the abutment block 63 is placed inside the placement groove 7. A guide rod 8 is fixedly connected to the side of the abutment block 63 facing the handwheel 62. A guide hole 9 is commonly provided on the top block 1 and the abutment block 63. A plurality of anti-slip bumps 10 are fixed on the side of the abutment block 63 away from the handwheel 62.

[0038] Reference Figure 1 and Figure 2 After the connecting bolt 4 is fixedly connected to the traction sheave 17, the operator rotates the hand wheel 62 to drive the threaded rod 61 to rotate, and the abutment block 63 abuts against the traction machine 16, so that the top block 1 and the fixed plate 2 are driven by the threaded rod 61 to move in the direction away from the traction machine 16, and then it helps to drive the traction sheave 17 to move synchronously in the direction away from the traction machine 16, and remove the traction sheave 17 from the traction machine 16, which helps to improve the convenience of operation during the removal of the traction sheave 17, thereby helping to reduce the time consumption of removing the traction sheave 17. The guide rod 8 helps to guide the moving direction of the top block 1 and the fixed plate 2, thereby helping to improve the accuracy of the moving direction of the top block 1 and the fixed plate 2, and then helps to improve the accuracy of the moving direction of the traction sheave 17, and helps to improve the smoothness of removing the traction sheave 17 from the traction machine 16.

[0039] The implementation principle of the embodiment of the present application is as follows: before placing the top block 1 and the fixing plate 2, the operator inserts the multiple plug-in parts 531 into the corresponding plug-in holes 11, so that the positions of the fixing plate 2 and the positioning collar 51 remain relatively fixed. The operator sleeves the positioning collar 51 onto the wheel barrel of the traction wheel 17, and rotates the positioning collar 51, so that the top block 1 and the fixing plate 2 rotate to the set position, and the operator rotates the connecting bolt 4, so that the connecting bolt 4 is threadedly fixedly connected with the traction wheel 17.

[0040] When the operator rotates the connecting bolt 4, the connecting spring 122 is gradually forced to shrink into the annular groove 15 until the head of the connecting bolt 4 is pressed against the anti-loosening washer 121, which helps prevent the connection between the connecting bolt 4 and the traction wheel 17 from loosening, thereby helping to improve the connection stability between the connecting bolt 4 and the traction wheel 17. After the head of the connecting bolt 4 is pressed against the anti-loosening washer 121, the anti-reverse ratchet 131 and the anti-reverse pawl 132 will bite each other, thereby helping to prevent the reverse rotation of the connecting bolt 4, thereby helping to further improve the connection stability between the connecting bolt 4 and the traction wheel 17.

[0041] When the connecting bolt 4 is fixedly connected to the traction sheave 17, the operator turns the hand wheel 62 to drive the threaded rod 61 to rotate, and at the same time the abutment block 63 abuts against the traction machine 16, which helps to move the top block 1 and the fixing plate 2 in the direction away from the traction machine 16 driven by the threaded rod 61, and then helps to drive the traction sheave 17 to move synchronously in the direction away from the traction machine 16, and remove the traction sheave 17 from the traction machine 16, which helps to improve the convenience of operation during the disassembly of the traction sheave 17, thereby helping to reduce the time spent on disassembly of the traction sheave 17.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
