Description

Technical Field

[0001] The utility model relates to the technical field related to elevators, in particular to a traction wheel provided with an anti-dropping clamping structure. Background Art

[0002] The traction wheel is an important part of the elevator. It is set on the traction machine and is a device for transmitting traction power. It uses the friction between the traction wire rope and the rope groove on the traction wheel rim to transmit power, so that the elevator car can be lifted and lowered. For example, a traction wheel with an anti-rope detachment prevention function with the publication number CN209275931U includes a wheel body, and the wheel surface of the wheel body is provided with a plurality of rope grooves arranged side by side in the circumferential direction. The part of the wheel body between the rope grooves is a spacing part. The traction wheel also includes an anti-detachment component, which includes two connecting plates and a limiting plate. The two connecting plates are fixed at both ends of the limiting plate and are respectively located on both sides of the wheel body. The limiting plate is located above the wheel body and blocks the rope grooves. The end faces on both sides of the wheel body are provided with guide grooves coaxial with the wheel body. A guide rod is fixedly provided on the side of the connecting plate close to the wheel body. The free end of the guide rod is located in the guide groove and slides with the guide groove. The problem that the traction rope is easy to detach from the groove in the prior art is solved, and the effect of reducing the possibility of the traction rope detaching from the groove is achieved. However, the anti-rope traction wheel still has the following disadvantages in actual use:

[0003] The traditional traction wheel needs to rotate during operation, and the wire rope is easy to slip out of its groove during rotation, thus affecting the normal operation of the elevator. After the wire rope on the traction wheel is limited, it is inconvenient for subsequent maintenance. In addition, the wire rope is in friction contact with the traction wheel for a long time, and dust will adhere between the two. The dust affects the smoothness of its transmission, which is not only prone to jamming, but also reduces the service life of related components. In view of the above problems, it is urgently necessary to carry out innovative design based on the original traction wheel. Utility Model Content

[0004] The utility model aims to provide a traction sheave with an anti-slip engagement structure to solve the problem proposed in the above background technology that the traditional traction sheave needs to rotate during operation, and the wire rope is easy to slip out of its groove during rotation, thereby affecting the normal operation of the elevator. After the wire rope on the traction sheave is limited, it is inconvenient to perform subsequent maintenance on it. In addition, the wire rope is in frictional contact with the traction sheave for a long time, and dust will adhere between the two. The dust affects the smoothness of the transmission, which is not only prone to jamming, but also reduces the service life of related components.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a traction wheel with an anti-dropping engaging structure is provided, and a support plate is provided, and a driving shaft is rotatably penetrated inside the two support plates, and a wheel body is fixedly sleeved in the middle position of the driving shaft, and a steel wire rope is provided in a groove outside the wheel body;

[0006] It also includes: an adjustment shaft, which passes through the corner of the support plate, the adjustment shafts are connected to each other through a first pulley mechanism, and a limit plate is sleeved on the outer side of the adjustment shaft;

[0007] The driving shaft is connected to the movable shaft through a second pulley mechanism, and the movable shaft is movably arranged above the supporting plate.

[0008] Preferably, both ends of the adjustment shaft are rotatably connected to the support plate, and two sections of thread grooves in opposite directions are symmetrically arranged on the adjustment shaft. When one of the adjustment shafts is rotated, the adjustment shafts with equal angles can be driven to rotate synchronously through the transmission of the first pulley mechanism.

[0009] Preferably, the adjusting shafts are distributed at equal angles on the support plate, and the adjusting shafts and the limiting plates are threadedly connected. When the adjusting shafts rotate, the two limiting plates can be driven to move relative to each other through thread transmission with the limiting plates.

[0010] Preferably, the cross-section of the limit plate is an "L"-shaped structure, and the moving directions of the two limit plates are opposite, and the side of the limit plate close to the wheel body is an arc structure, and the limit plate slides in contact with the surface of the wheel body. The limit plate is used to limit the wire rope by sliding in contact with the surface of the wheel body.

[0011] Preferably, cleaning brushes are evenly arranged on the outer side of the movable shaft, and the cleaning brushes are in close contact with the steel wire rope. The movable shaft rotates synchronously with the driving shaft, and the cleaning brushes are in contact with the steel wire rope to clean it.

[0012] Preferably, the movable shaft and the driving shaft have the same direction of rotation, and the rotation speed of the driving shaft is greater than the rotation speed of the movable shaft. The movable shaft improves the cleaning efficiency by driving the cleaning brush to rotate at a high speed.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the traction wheel with an anti-slipping engaging structure is provided with a structure for limiting the position of the wire rope on the traction wheel, which can avoid the phenomenon of the wire rope slipping during the operation of the traction wheel, and also facilitate the subsequent maintenance of the wire rope. At the same time, the dust adhering between the wire rope and the traction wheel can be cleaned to ensure smooth transmission of the two, and prevent jamming due to dust and thus affecting the service life. The specific contents are as follows:

[0014] 1. Rotate one of the adjustment shafts, and realize the synchronous rotation of the adjustment shafts with equal angle distribution through the transmission of the first pulley mechanism. Then, through the threaded transmission of the adjustment shaft and the limit plate, the two limit plates can be driven to approach each other. The limit plates slide on the wheel body. After moving to the limit, the two adjacent limit plates contact each other to limit the wire rope, so as to prevent the wire rope from slipping out of the groove during the transmission process.

[0015] 2. When the driving shaft rotates, the movable shaft can be driven to rotate through the second pulley mechanism, and the movable shaft drives the cleaning brush to rotate rapidly, which can sweep the surface of the wire rope to clean the dust adhered to the wire rope, avoiding jamming due to a large amount of dust adhesion and even affecting the service life.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0025] Embodiment 1: In order to solve the problems existing in the prior art, this embodiment adopts the following technical scheme: a traction wheel with an anti-disengagement locking structure is provided, and a support plate 1 is provided. A drive shaft 2 is rotated inside the two support plates 1, and a wheel body 3 is fixedly sleeved in the middle position of the drive shaft 2, and a wire rope 4 is arranged in the groove on the outer side of the wheel body 3; it also includes: an adjusting shaft 5, which passes through the corner of the support plate 1, and the adjusting shafts 5 are interconnected by a first pulley mechanism 6, and a limit plate 7 is sleeved on the outer side of the adjusting shaft 5; the drive shaft 2 is connected to each other through a second pulley mechanism 8 and a movable shaft 9, and the movable shaft 9 is movably arranged above the support plate 1.

[0026] The existing traction wheel needs to rotate during operation, and the wire rope 4 is easy to slip out of its groove during rotation, thereby affecting the normal operation of the elevator. After the wire rope 4 on the traction wheel is limited, it is inconvenient to perform subsequent maintenance. Figure 1-Figure 5 As shown, both ends of the adjusting shaft 5 are rotatably connected to the supporting plate 1, and two sections of threaded grooves in opposite directions are symmetrically arranged on the adjusting shaft 5; the adjusting shaft 5 is distributed at equal angles on the supporting plate 1, and the adjusting shaft 5 and the limiting plate 7 are threadedly connected; the cross-section of the limiting plate 7 is an "L"-shaped structure, and the moving directions of the two limiting plates 7 are opposite, and the side of the limiting plate 7 close to the wheel body 3 is a curved surface structure, and the limiting plate 7 slides in contact with the surface of the wheel body 3; first, the wire rope 4 is clamped and installed in the groove on the wheel body 3, and then the wire rope 4 is rotated. Move one of the adjusting shafts 5, and realize the synchronous rotation of the adjusting shafts 5 with equal angle distribution through the transmission of the first pulley mechanism 6. Then, the two limiting plates 7 can be driven to approach each other through the threaded transmission of the adjusting shaft 5 and the limiting plate 7. The limiting plates 7 slide on the wheel body 3. After moving to the limit, the two adjacent limiting plates 7 contact each other, so as to limit the wire rope 4 and prevent the wire rope 4 from slipping out of the groove during the transmission process. When the wire rope 4 needs to be inspected, the adjusting shaft 5 can be rotated in the opposite direction, so the operation is convenient.

[0027] Embodiment 2: The steel wire rope 4 on the existing traction wheel is in frictional contact with the traction wheel for a long time, and dust will adhere between the two. The dust affects the smoothness of its transmission, which is not only prone to jamming, but also reduces the service life of related components. Therefore, this embodiment adopts the following technical solutions, such as Figure 6 As shown, cleaning brushes 10 are evenly arranged on the outer side of the movable shaft 9, and the cleaning brushes 10 are in close contact with the steel wire rope 4; the movable shaft 9 and the driving shaft 2 have the same direction of rotation, and the rotation speed of the driving shaft 2 is greater than the rotation speed of the movable shaft 9; when the driving shaft 2 rotates, the movable shaft 9 can be driven to rotate by the second pulley mechanism 8, and the movable shaft 9 drives the cleaning brush 10 to rotate rapidly, which can sweep the surface of the steel wire rope 4 to clean the dust adhered to the steel wire rope 4, thereby ensuring the smoothness of the transmission and avoiding the phenomenon of jamming due to the adhesion of a large amount of dust and even affecting the service life.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
