Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of traction machine protective covers, and in particular to an adjustable elevator traction machine protective cover. Background Technology
[0002] The traction machine, also known as the elevator main unit, is the power equipment of the elevator. It consists of an electric motor, a gearbox, and a brake. The traction steel wire rope is connected to the car at one end and to the counterweight at the other end through the traction sheave. To ensure that the car and counterweight run along the guide rails in the hoistway without rubbing against each other, the traction sheave and guide sheave on the traction machine need to have a certain distance between them. To ensure the normal operation of the traction machine and prevent foreign objects from obstructing the operation of the traction sheave and guide sheave, protective covers are usually installed above the traction sheave and guide sheave of the traction machine.
[0003] In the existing technology, the traction machine protective cover used in elevators is a one-piece design. Depending on the different wrap angles of the traction machine and the different inclination lengths of the wire rope, each elevator needs to have its own protective cover made, which makes on-site processing quite troublesome later.
[0004] An existing patent (publication number: CN212953740U) discloses an elevator with a retractable protective cover. This patent changes the existing one-piece protective cover to a split retractable one, which can be used regardless of the size of the traction machine wrap angle or the length of the wire rope inclination. It can also mass-produce spare parts, saving time.
[0005] To address the aforementioned issues, while existing patents offer solutions that can improve versatility by converting the integrated design to a retractable one, in practical use, changes in elevator car structure dimensions and shaft specifications inevitably lead to variations in the distance between the traction sheave and guide sheave. These variations can cause interference between the original protective cover and the traction steel wire rope, necessitating adjustments to the protective cover based on the guide sheave's position, thus limiting its usability. Summary of the Invention
[0006] The purpose of this utility model is to provide an adjustable elevator traction machine protective cover, which allows the length and angle of the protective cover to be adjusted when the traction wheel and guide wheel of the traction machine need to be installed or the spacing needs to be adjusted according to different spaces, thereby achieving a protective effect.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides a technical solution:
[0028] Please see Figures 1 to 3An adjustable elevator traction machine protective cover includes an assembly frame 1. A support frame 2 is fixedly installed on one side of the top of the assembly frame 1, and a crossbeam 3 is fixedly installed on the other side of the top of the assembly frame 1. A protective mechanism 4 is provided on one side of the crossbeam 3. The protective mechanism 4 includes a rotating block 401, which is rotatably connected to one side of the crossbeam 3. A limit turntable 402 is fixedly installed on the outer wall of the crossbeam 3 facing the rotating block 401. A connecting rod 403 is fixedly installed on the top of the rotating block 401, and a rotating shell 404 is fixedly installed on the top of the connecting rod 403. A protective shell 405 extends through the interior of the rotating shell 404. A sliding shell 406 is fixedly installed at one end, and a fixed shell 407 is slidably connected to one end of the sliding shell 406. An adjusting rod 408 extends through the interior of the fixed shell 407, and a threaded rod 409 is fixedly installed at one end of the adjusting rod 408. A rotating shaft 410 extends through the interior of the protective shell 405. An abutment roller 411 is rotatably connected inside the sliding shell 406. A rotating block 401 forms a rotating structure with the crossbeam 3 through a limiting turntable 402. The rotating block 401 is movably connected to the rotating shell 404 through a connecting rod 403. The threaded rod 409 penetrates into the interior of the sliding shell 406, and the sliding shell 406 is threadedly connected to the threaded rod 409.
[0029] By adopting the above technical solution, firstly, the assembly frame 1, the support frame 2, and the crossbeam 3 are fixed together, and the traction machine is fixed according to the site conditions, so that the traction wheel and the guide wheel are located in the same plane between the support frame 2 and the crossbeam 3. Then, according to the position of the traction wheel and the guide wheel, the adjusting rod 408 is rotated, thereby driving the threaded rod 409 to rotate, so that the fixed shell 407 slides and extends along the sliding shell 406. At the same time, the sliding shell 406 is fixed by the protective shell 405, and the rotating shaft 410 is rotatably connected to the rotating shell 404. The rotating shell 404 slides with the connecting rod 403, and can rotate under the cooperation of the rotating block 401 and the limiting turntable 402. The angle of the rotating shell 404 can be adjusted according to the position of the guide wheel, further improving the overall applicability and avoiding the impact of position adjustment on the wrap angle, which would limit the operation and prevent normal operation. The position of the sliding shell 406 must always correspond to the top of the traction wheel and be pressed by the abutment roller 411 to provide a certain support effect and maintain the smoothness of the traction wheel rotation process.
[0030] Specifically, such as Figure 1 and Figure 4As shown, a sliding stage 5 is fixedly installed at the bottom of the fixed shell 407. A positioning mechanism 6 is provided on one side of the sliding stage 5. The positioning mechanism 6 includes an assembly groove 601, which is opened in the axial interior of the sliding stage 5. A roller 602 is rotatably connected inside the assembly groove 601. A connecting plate 603 is fixedly installed on one side of the sliding stage 5. An installation block 604 is fixedly installed on the top of the connecting plate 603. A spring 605 is embedded inside the installation block 604. A positioning block 606 is fixedly installed on the top of the spring 605. A positioning hole 607 is opened on the outer wall of the crossbeam 3 corresponding to the position of the positioning block 606.
[0031] By adopting the above technical solution, during the specific adjustment process, the fixed shell 407 moves along the crossbeam 3 via the sliding table 5, and can adjust the position of the traction wheel according to the positioning of the traction machine. During the adjustment, the assembly groove 601 and the roller 602 slide against the crossbeam 3, improving the smoothness of the adjustment process and avoiding excessive friction. After the adjustment is completed, the spring 605 embedded in the mounting block 604 at the top of the connecting plate 603 elastically pushes the positioning block 606 into the positioning hole 607 to form a locking situation, thereby stabilizing the entire protective cover. When disassembly or assembly is required, the positioning block 606 can be pressed to insert into and out of the positioning hole 607.
[0032] Working principle: The support frame 2, fixed by the assembly frame 1, is used to fix the traction machine. The traction sheave and guide wheel are located between the support frame 2 and the crossbeam 3. Rotating the adjusting rod 408 allows the threaded rod 409 to rotate. Through a threaded connection with the sliding housing 406, and in conjunction with the sliding housing 406 fixed to the protective housing 405, the distance between the fixed housing 407 and the protective housing 405 can be adjusted. This is achieved through the rotating block 401, the limiting turntable 402, and the connecting rod 403. Simultaneously, the rotating housing 404 is rotatably connected to the protective housing 405 via the rotating shaft 410. This allows for adjustment and protection based on the position of the traction sheave and guide wheel on site, and enables adaptive angle adjustment during adjustment to avoid corner wrapping. The limited position caused by the influence makes it impossible to correspond with the traction wheel and the guide wheel. With the help of the abutment roller 411, the sliding shell 406 can rotate and abut against the traction wheel, thereby providing a certain support effect for the sliding shell 406. During the adjustment process, the fixed shell 407 slides stably along the crossbeam 3 via the sliding table 5. The rotational abutment of the assembly groove 601 and the roller 602 can improve the smoothness of the sliding process. The mounting block 604 fixed by the connecting plate 603 is internally fitted with a spring 605, which can elastically push the positioning block 606 through the positioning hole 607 for limiting, thereby providing stability after the adjustment is completed. When disassembling and adjusting, the positioning block 606 can be pressed to disengage from the positioning hole 607 and enter the mounting block 604.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
