Description

Technical Field

[0001] This utility model relates to the field of elevator traction sheave technology, specifically a movable elevator traction sheave. Background Technology

[0002] The elevator traction sheave (or pulley) is a core component of the elevator drive system, primarily responsible for driving the elevator wire rope or pulley (or cable or sling) up and down in the elevator shaft. Traditional elevator traction sheaves are usually fixed and closely related to the elevator's operating speed and load. With the development of elevator technology, movable elevator traction sheaves have emerged. Their function is mainly reflected in the ability to adjust the position and angle of the traction sheave as needed, thereby affecting the elevator's traction force, running smoothness, and energy efficiency.

[0003] A movable elevator traction sheave technology solution is disclosed in the prior art. This solution includes a power socket at the front end of the housing, a power mounting base detachably installed on the power socket, three interfaces on the power mounting base, a fixing component at the rear end of the housing, a network interface and multiple USB interfaces at the front end of the housing, and a communication component inside the housing. The communication component is connected to the network interface and USB interfaces respectively. The power mounting base of this utility model is set separately, so it can be replaced without opening the inside of the housing when damaged or burned, which is convenient to use. In addition, the housing of this utility model can protect the internal communication component from damage during use. Furthermore, the fixing component of this utility model facilitates the installation and fixation of the housing on the rack inside the machine room.

[0004] In this scheme, the operator slides the movable sleeve on the central rotating shaft to further move the traction sheave for displacement adjustment. Then, the operator fixes the fixing hole and the corresponding adjustment through hole with bolts, fixes the movable sleeve on the central rotating shaft, and then fixes the traction sheave mechanism to the movable sleeve. The movable sleeve is fixed to the central rotating shaft with bolts. If the fixation is not firm, it may cause unnecessary displacement of the traction sheave during operation, increasing the risk of equipment failure. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1-4As shown, in this embodiment, a movable elevator traction sheave includes a traction sheave mechanism 100 and a traction sheave fixing assembly 200. The traction sheave fixing assembly 200 includes: an outer ring shell 201, an inner ring 204 and a sliding block 208 formed on the inner side of the outer ring shell 201, the sliding block 208 being slidably connected to the inside of a sliding groove 108, the sliding groove 108 being formed on the outer side of a central shaft 102, the sliding block 208 being movable within the sliding groove 108 of the central shaft 102, the sliding block 208 being slidably connected to the inside of a movable sleeve shaft 104, and the sliding block 208 moving within the inner groove 105 of the movable sleeve shaft 104. The inner ring 204... The inner sleeve of 04 is fitted onto the outer side of the movable sleeve shaft 104. A displacement block 106 is installed on the inner side of the movable sleeve shaft 104. The displacement block 106 moves within the sliding groove 108 of the central shaft 102. A through hole 202 is provided inside the outer ring shell 201, and a corresponding slot 205 is provided inside the through hole 202. The slot 205 is located inside the central shaft 102. A retaining block 206 is connected through the through hole 202 and the slot 205. The retaining block 206 is tightened inside the outer ring shell 201 by an internal hex bolt 207. The outer ring shell 201 has a threaded hole 203. One end of the traction wheel mechanism 100 has a threaded groove 107 and a threaded hole 203. The traction sheave mechanism 100 is fixed to one end by an internal hex bolt 207 tightened into the threaded groove 107 and the outer shell 201. In actual use, the traction sheave in the elevator is first installed on the outside of the moving sleeve shaft 104. Then, the locating block 106 on the inside of the moving sleeve shaft 104 moves and adjusts the traction sheave within the sliding groove 108 of the central shaft 102, thereby allowing the traction sheave to move and adjust its position on the central shaft 102. When the traction sheave moves to the corresponding position on the central shaft 102, the sliding block 208 is inserted into the sliding groove 108 on the outside of the central shaft 102, and the outer shell 201 passes through the through hole 20. The outer shell 201 is fixed to one end of the traction wheel mechanism 100 by the slot 205 of the central shaft 102 and the engagement of the locking block 206 with the slot 205. The outer shell 201 is further connected and fixed to one end of the traction wheel mechanism 100 by the internal hexagonal thread. The sliding block 208 is connected to the central shaft 102 through the sliding groove 108 and can move freely inside the sliding groove 108. The traction wheel fixing component 200 can be adjusted to avoid the moving sleeve shaft 104 being not firmly fixed on the central rotating shaft, prevent unnecessary displacement of the traction wheel during operation, and prevent the elevator traction wheel from being moved and re-fixed by the staff.

[0023] The traction sheave fixing assembly 200, through the snap-fit ​​structure between the through hole 202 of the outer ring shell 201 and the slot 205 of the central shaft 102, and the fastening effect of the snap-fit ​​block 206 and the internal hex bolt 207, ensures a stable connection between the traction sheave fixing assembly 200 and the traction sheave mechanism 100. This avoids the movable sleeve shaft 104 being not securely fixed on the central rotating shaft, preventing unnecessary displacement of the traction sheave during operation. At the same time, it also facilitates the operation of staff when repositioning and refixing the elevator's traction sheave.

[0024] like Figure 1-3 , Figure 5 As shown, a connecting hole 109 is provided inside the central shaft 102. A corresponding movable sleeve shaft 104 is located within the connecting hole 109. An internal hex bolt 207 is rotatably connected between the connecting hole 109 and the movable sleeve shaft 104. The traction sheave mechanism 100 has a rope groove 103, and a wheel groove pad 101 is fixedly installed inside the rope groove 103. The installation of the wheel groove pad 101 inside the rope groove 103 provides friction reduction and protection. The material of the wheel groove pad 101 may have good wear resistance, thereby effectively reducing friction between the traction rope and the traction sheave, reducing wear on the rope groove 103, and extending the overall service life of the elevator traction system.

[0025] This utility model provides a movable elevator traction sheave, the specific working principle of which is as follows: First, the traction sheave in the elevator is installed on the outside of the movable sleeve shaft 104. Then, the movable block 106 on the inner side of the movable sleeve shaft 104 is used to move and adjust it within the sliding groove 108 of the central shaft 102. This further drives the traction sheave to adjust its position on the central shaft 102. When the traction sheave moves to the corresponding position on the central shaft 102, the sliding block 208 is inserted into the sliding groove 108 on the outside of the central shaft 102, and the sheave is adjusted through the through hole 202 of the outer ring shell 201 and the slot 20 of the central shaft 102. 5. The outer ring can be fixed on the central shaft 102 by the engagement of the locking block 206 and the locking groove 205. Furthermore, the outer ring shell 201 is connected and fixed to one end of the traction wheel mechanism 100 by the internal hexagonal thread. The sliding block 208 can move freely inside the sliding groove 108 through the connection between the sliding groove 108 and the central shaft 102. The traction wheel fixing component 200 can be adjusted to avoid the moving sleeve shaft 104 being not firmly fixed on the central rotating shaft, prevent unnecessary displacement of the traction wheel during operation, and prevent the elevator traction wheel from being moved and re-fixed by the staff.
