Abstract
Description
Technical Field
[0001] This application relates to the field of elevator safety protection technology, specifically to an integrated protective component for elevator traction wheels and the field of traction machine technology. Background Technology
[0002] As the core drive unit of an elevator, the traction machine poses risks of wire rope slippage and accidental contact during operation, requiring the installation of appropriate safety components such as protective plates and anti-slip bars. Current methods, where various functional components have independent mounting points on the main unit, result in a complex structure, large dimensions, and high space requirements, making it unsuitable for placement in compact machine room environments. Furthermore, the complex structural features increase the difficulty of machining and manufacturing costs.
[0003] In addition, the protective plates are mostly fixed or semi-fixed connections, making it difficult to adjust the angle and adapt to different installation postures or models of traction sheaves, resulting in poor versatility. Although the anti-jump bar is fixed to the machine body with fasteners, its adjustment freedom is limited, and the adjustment space for its relative position with the traction sheave groove is limited. When the installation angle of the wire rope changes, it often needs to be redesigned and matched, resulting in insufficient adaptability.
[0004] This results in the need to repeatedly disassemble components such as protective plates and anti-jump bars during maintenance, when replacing wire ropes or overhauling traction sheaves, making the operation cumbersome and time-consuming.
[0005] Therefore, there is an urgent need for a modular solution that integrates functions such as protective plates and anti-jump bars into one unit to simplify the main unit structure, improve adjustment flexibility, and enable rapid maintenance. Summary of the Invention
[0006] This application proposes an integrated protective component for elevator traction wheels and a traction machine. Through integrated design, it achieves multi-directional adjustability and overall assembly and disassembly, effectively improving the applicability of safety protection and engineering efficiency.
[0007] To achieve the above objectives, the present application adopts the following technical solution: In the first aspect, this application proposes an integrated protective assembly for elevator traction wheels, including a mounting bracket, a protective main board, a protective side plate, and an anti-jump rod; The mounting bracket is fixed to the mounting protrusion on the main body, the protective main board is fixedly connected to the mounting bracket, and the protective side plate is symmetrically arranged on the left and right sides of the protective main board and is hinged to the protective main board and can be adjusted at an angle to form an overall protective structure for the traction wheel. The mounting bracket is provided with a first waist-shaped groove, one end of the anti-jump rod is installed on the first waist-shaped groove, and the other end extends to both sides of the traction wheel.
[0008] Thus, by integrating the protective mainboard, protective side plates, and anti-jump rod onto the mounting bracket, a modular, integrated protective assembly is formed. This eliminates the need for multiple independent mounting points on the main unit, significantly simplifying the traction machine structure, reducing its size, and lowering processing difficulty and manufacturing costs. The adjustable angle design of the protective side plates enhances its adaptability to different traction sheave models; the anti-jump rod achieves angle adjustment through the first waist-shaped groove, flexibly adapting to the wire rope installation angle, avoiding the risk of jumping off the groove, and improving versatility and on-site installation efficiency.
[0009] In some possible implementations, the anti-jump rod slides into the first waist-shaped groove and is locked in place by a locking nut, and the angle of the anti-jump rod can be adjusted from 0° to 70° from horizontal upward.
[0010] In some possible implementations, the mounting bracket has a support portion for docking and fixing with the mounting protrusion, and an oblong portion disposed around the support portion, wherein the first oblong groove is disposed on the oblong portion.
[0011] In some possible implementations, the mounting bracket has a handwheel limiting hole on the outer periphery of the first waist-shaped groove.
[0012] In some possible implementations, the upper end of the protective motherboard is fixed to the upper end of the mounting bracket, and the lower end is fixed to the lower end of the host body.
[0013] In some possible implementations, the protective motherboard extends support arms to the lower end of the mounting bracket and the main unit for fixing thereto.
[0014] In some possible implementations, the protective side plate is provided with one or more second oblong grooves for guiding its angle adjustment and is locked and positioned on the protective main plate by locking screws.
[0015] In some possible implementations, there are multiple second waist-shaped grooves arranged circumferentially, and the angle of the protective side plate can be adjusted from 0° to 90° from horizontal upward.
[0016] Secondly, this application also proposes a traction machine, including a main body and a traction sheave, wherein the main body is provided with mounting protrusions and uses the elevator traction sheave integrated protection component as described above.
[0017] In some possible implementations, a support plate is also included, on which the lower end of the protective motherboard is fixed. Attached Figure Description

[0021] like Figures 1 to 3 As shown, this embodiment provides an integrated protective assembly for elevator traction sheaves, which includes a mounting bracket 1, a protective main board 2, a protective side plate 3, and an anti-jump rod 4. Through integrated design, this assembly integrates multiple safety function units originally scattered across the main unit body 100 into a modular whole, significantly simplifying the traction machine structure and improving installation and maintenance efficiency.
[0022] Specifically, the mounting bracket 1 serves as the load-bearing foundation of the entire protective assembly, and is fixed to the mounting protrusion 110 pre-set on the main unit body 100 via its support portion 12. An oblong portion 13 extends from the periphery of the support portion 12, and this oblong portion 13 has a first oblong groove 11. The anti-jump rod 4 is fixed to the first oblong groove 11 by a locking nut. The first oblong groove 11 is used to realize the angle adjustment function of the anti-jump rod 4. The mounting bracket 1 is connected to the mounting protrusion 110 by bolts passing through the support portion 12, ensuring the stability and reliability of the overall structure. Since all functional components are integrated on the mounting bracket 1, there is no need to set multiple independent mounting points on the main unit body 100, effectively reducing the complexity of the body structure and the size, making it particularly suitable for compact computer room environments with limited space.
[0023] It should be noted that the description of locking nuts and locking screws used in this application is a commonly used mechanical connection structure in the industry, and they are not marked in detail in the accompanying drawings.
[0024] The upper end of the protective motherboard 2 is connected to the upper end of the mounting bracket 1 via an extended support arm 21, and its lower end is connected to the lower structure of the main unit 100 via the extended support arm 21, specifically fixed to the support plate 120 (e.g., Figure 5 , Figure 6 (As shown). This dual-point fixing method enhances the overall rigidity of the protective mainboard 2, preventing deformation due to vibration or external forces and improving safety and stability during long-term operation. The design of the support arm 21 not only improves the connection strength but also facilitates compatible installation between different models of traction machines.
[0025] The protective side plates 3 are symmetrically arranged on the left and right sides of the protective main plate 2 and are connected to the protective main plate 2 via a hinge structure, allowing for angle adjustment from 0° to 90° horizontally upwards (e.g., Figure 9 , Figure 10 (As shown). Each protective side plate 3 is provided with one or more second waist-shaped grooves 31. The locking screw passes through the second waist-shaped groove 31 and is fixed to the protective main plate 2. During adjustment, the screw can be loosened to rotate the protective side plate 3 to the required angle, and then it can be tightened again. In a preferred embodiment, there are two second waist-shaped grooves 31, which are arranged in a ring with an interval. This structure allows the protective side plate 3 to flexibly adapt to traction sheaves 200 of different diameters and installation postures, which significantly enhances the versatility and field adaptability of the components. When it is necessary to replace the wire rope or repair the traction sheave 200, the protective side plate 3 can be rotated to the open position to form an open channel without the need for complete disassembly, which greatly simplifies the maintenance operation process.
[0026] One end of the anti-jump rod 4 is installed in the first oblong groove 11 of the mounting bracket 1, and the other end extends towards both sides of the traction sheave 200 to prevent the wire rope from jumping out of the groove during operation. The anti-jump rod 4 slides in the first oblong groove 11, and its angle relative to the horizontal plane can be adjusted by rotation, and it is locked in place by a locking nut. The adjustment range is from 0° to 70° upward from the horizontal, covering the deflection angle requirements of most elevator wire ropes (such as...). Figure 7 and Figure 8 (As shown). This stepless adjustment capability allows the same protective component to be adapted to various traction sheave arrangement schemes, avoiding the need to redesign the anti-jump device due to changes in the wire rope angle, and improving the product's engineering applicability and economy.
[0027] Furthermore, in the outer peripheral region of the first waist-shaped groove 11, the mounting bracket 1 is also provided with a handwheel limiting hole 14 (e.g., Figure 4 (As shown). The load-bearing structure of the handwheel 300 is integrated into the mounting bracket 1, which avoids reserving separate installation space on the main body 100, further optimizes the structural layout and improves space utilization.
[0028] In summary, this embodiment integrates the functions of the protective main board 2, protective side plate 3, anti-jump rod 4, and handwheel limiting hole 14 onto the mounting bracket 1, forming a modular unit that can be installed and disassembled as a whole. This design not only significantly reduces the processing complexity and manufacturing cost of the main unit 100, but also achieves independent stepless adjustment of the protective angle and anti-jump angle, greatly improving its adaptability to different models of traction machines. Simultaneously, all adjustments and fixations are completed through the cooperation of the slotted groove and locking components, resulting in a simple structure, convenient operation, and high safety and reliability. During maintenance, there is no need to repeatedly disassemble multiple parts; only the adjustment or removal of the corresponding components is required to complete the operation, effectively shortening downtime and improving maintenance efficiency.
[0029] Furthermore, this application also provides a traction machine that utilizes the aforementioned integrated protective component for elevator traction sheaves. This traction machine includes a main body 100 and a traction sheave 200. The main body 100 is provided with mounting protrusions 110 for mounting the aforementioned protective component. This traction machine, while ensuring safety performance, possesses higher integration and engineering flexibility, making it suitable for various elevator drive systems.
[0030] As stated above, this case protects an integrated protective component for elevator traction sheaves and a traction machine. All technical solutions that are the same as or similar to those in this case should be considered to fall within the scope of protection of this case.
