Description

Technical Field

[0001] This utility model relates to the field of elevator traction sheave technology, and in particular to elevator traction sheave assembly. Background Technology

[0002] A traction sheave is a rope sheave on a traction machine, also called a traction rope sheave or drive rope sheave. It is a device that transmits traction power in an elevator. It uses the friction between the traction steel wire rope and the rope groove on the rim of the traction sheave to transmit power. It is mounted on the turbine shaft in the reducer. In gearless traction machines, it is mounted next to the brake and on the same axis as the motor shaft. To ensure the safe operation of the elevator, a safe and effective traction sheave must be used to prevent accidents and ensure the safety of people inside the elevator.

[0003] An existing patent, CN219449159U, describes an elevator traction sheave. This patent employs a lifting mechanism, a drive assembly, and a brake block. When the elevator falls unexpectedly, the brake block descends rapidly under the action of the lifting mechanism and drive assembly and acts on the wheel body. The anti-slip teeth of the brake block can lock the traction rope on the wheel body, enabling the traction sheave to achieve emergency braking and preventing injury to people inside the elevator during an unexpected fall.

[0004] The inventors discovered in their daily work that after a certain period of use, dust and debris accumulate in the traction sheave groove, increasing friction and affecting the normal operation of the traction sheave. This may cause the elevator to require more energy to operate, reducing traction efficiency and increasing energy consumption. It also requires manual cleaning by workers, increasing their workload. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned above in the background art by proposing an elevator traction sheave assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an elevator traction sheave assembly, including a mounting frame. The surface of the mounting frame has four mounting holes, which are adapted to the installation of load-bearing beams according to GB / T 700-2006 standard. A vertical plate is fixedly mounted on the surface of the mounting frame, and a motor is fixedly mounted on the surface of the vertical plate. The output end of the motor is fixedly mounted with a wheel body through a TL6 type flexible coupling. The annular sidewall of the wheel body has multiple wheel grooves evenly distributed. The depth of the wheel grooves is 25mm, and the groove width is adapted to an 8mm diameter traction rope. The surface of the mounting frame is provided with a cleaning device for cleaning the wheel grooves.

[0007] Preferably, the cleaning device includes two sleeves fixedly installed on the surface of the mounting frame. A sliding rod is slidably connected inside each of the two sleeves. A fixing plate is fixedly installed at the end of the sliding rod away from the sleeve. A mounting seat is fixedly installed between the two fixing plates. A mounting groove is opened on the surface of the mounting seat. A brush seat is movably installed inside the mounting groove. Multiple brush bodies are fixedly installed on the surface of the brush seat. The number of brush bodies corresponds to the number of wheel grooves.

[0008] Preferably, the surface of the mounting bracket has a groove, and two slide rods are fixedly installed between the inner walls of the two sides of the groove. Two sliding seats are slidably connected between the two slide rods, and the two sliding seats and the mounting seat are hinged together by a hinge plate.

[0009] Preferably, a support plate is fixedly installed on the inner bottom surface of the groove, and a double-headed electric telescopic rod, model JEA-100, with a stroke of 100mm and a thrust of 500N, is fixedly installed on the surface of the support plate. The two output ends of the double-headed electric telescopic rod are fixedly connected to the two sliding seats.

[0010] Preferably, the brush body (made of PA66 nylon bristles with a hardness of 80 Shore D and a bristle density of 50 bristles / cm²) and the sleeve and sliding rod are fitted with an H7 / f6 clearance.

[0011] The effect achieved by the above components is that the brush body can make active contact with the inner wall of the wheel groove. When the traction wheel rotates, the brush body can brush away the dust and impurities adhering to the wheel groove, avoiding the accumulation of dust and debris in the traction wheel groove, which would increase friction and reduce energy consumption. At the same time, it eliminates the need for manual cleaning by workers, reducing their workload.

[0012] Preferably, one side surface of the brush holder is provided with two limiting devices that limit itself inside the mounting groove. The limiting device includes two transverse grooves formed on one side surface of the brush holder. A movable plate is slidably connected inside the transverse groove.

[0024] Example 1, such as Figure 1-5As shown, the elevator traction sheave assembly includes a mounting frame 1. The surface of the mounting frame 1 has four mounting holes 4, which are adapted to the installation of load-bearing beams according to GB / T 700-2006 standard. A vertical plate 5 is fixedly mounted on the surface of the mounting frame 1. A motor 6 is fixedly mounted on the surface of the vertical plate 5. The output end of the motor 6 is fixedly mounted with a wheel body 7 through a TL6 type flexible coupling. The annular sidewall of the wheel body 7 is evenly provided with multiple wheel grooves 8. The depth of the wheel grooves 8 is 25mm, and the groove width is adapted to an 8mm diameter traction rope. The surface of the mounting frame 1 is provided with a cleaning device 2 for cleaning the wheel grooves 8.

[0025] Reference Figure 1-5 As shown in this embodiment: the cleaning device 2 includes two sleeves 201 fixedly installed on the surface of the mounting frame 1. Sliding rods 202 are slidably connected inside each sleeve 201. A fixing plate 203 is fixedly installed at one end of the sliding rod 202 away from the sleeve 201. A mounting base 204 is fixedly installed between the two fixing plates 203. A mounting groove 205 is formed on the surface of the mounting base 204. A brush holder 206 is movably installed inside the mounting groove 205. Multiple brush bodies 207 are fixedly installed on the surface of the brush holder 206. The number of brush bodies 207 corresponds to the number of wheel grooves 8. A recessed groove is formed on the surface of the mounting frame 1. Two sliding rods 209 are fixedly installed between the inner walls of the two sides of the groove 208. Two sliding seats 210 are slidably connected between the two sliding rods 209. The two sliding seats 210 and the mounting base 204 are hinged by a hinge plate 211. A support plate 212 is fixedly installed on the inner bottom surface of the groove 208. A double-headed electric telescopic rod 213, model JEA-100, with a stroke of 100mm and a thrust of 500N, is fixedly installed on the surface of the support plate 212. The two output ends of the double-headed electric telescopic rod 213 are fixedly connected to the two sliding seats 210. The brush body 207 is made of PA66 nylon bristles with a hardness of 80. Shore D, with a bristle density of 50 bristles / cm², uses an H7 / f6 clearance fit between the sleeve 201 and the sliding rod 202, allowing the brush body 207 to make movable contact with the inner wall of the wheel groove 8. When the traction sheave rotates, the brush body 207 can brush away the dust and impurities adhering to the wheel groove 8, preventing dust and debris from accumulating in the traction sheave groove, increasing friction, reducing energy consumption, and eliminating the need for manual cleaning by workers, thus reducing their workload.

[0026] Reference Figure 3-5As shown in this embodiment: One side surface of the brush holder 206 is provided with two limiting devices 3 that confine themselves within the mounting groove 205. Each limiting device 3 includes two transverse grooves 31 formed on one side surface of the brush holder 206. A movable plate 32 is slidably connected inside the transverse grooves 31. A rod 33 is fixedly mounted on the surface of the movable plate 32. Insertion holes 34 are formed on the inner walls of both sides of the mounting groove 205. Two strip grooves 35 are formed on one side surface of the brush holder 206, and the strip grooves 35 are slidably connected inside... An L-shaped plate 36 is fixedly connected to a movable plate 32 at one end away from the strip groove 35. A bolt 37 is threadedly connected to the vertical end of the L-shaped plate 36. Two sets of threaded holes 38 are provided on one side surface of the brush holder 206. Each set of threaded holes 38 consists of multiple threaded holes 38. The setting of the insertion rod 33 and the insertion hole 34 serves to limit the brush holder 206 inside the mounting groove 205. The setting of the bolt 37 and the threaded hole 38 serves to limit the position of the L-shaped plate 36 inside the strip groove 35.

[0027] Working principle: When the device is needed, first use screws to install and fix the mounting bracket 1 in a suitable position through the mounting hole 4. Then, fix the steel rope to the wheel groove 8. Next, use the motor 6 to drive the traction sheave to rotate. When the wheel groove 8 needs to be cleaned after a period of use, first start the double-headed electric telescopic rod 213. The start of the double-headed electric telescopic rod 213 simultaneously drives the two sliding seats 210 to move closer to each other on the surface of the slide rod 209. The motor drives the hinge plate 211 to move, which in turn pushes the mounting base 204 upward. The upward movement of the mounting base 204 causes the fixing plate 203 to move upward, which in turn causes the sliding rod 202 to move outward from the inside of the sleeve 201. Simultaneously, the upward movement of the mounting base 204 also causes the brush holder 206 to move upward, which in turn causes the brush body 207 to move upward, bringing it into contact with the wheel groove 8. When the brush body 207 reaches the appropriate position, the dual-head motor is turned off. The telescopic rod 213 allows the brush to remove dust and impurities adhering to the wheel groove 8 when the wheel body 7 rotates, preventing dust and debris from accumulating in the traction wheel groove and increasing friction. When the brush body 207 needs replacement due to severe wear after a period of use, first loosen the bolt 37 and unscrew it from the threaded hole 38. The separation of the bolt 37 from the threaded hole 38 causes the L-shaped plate 36 to lose its restraint within the strip groove 35, allowing the L-shaped plate 36 to move within the strip groove 35. The moving plate 32 moves inside the transverse groove 31, which in turn moves the insert rod 33. The insert rod 33 moves so that it moves out of the insertion hole 34. The separation of the insert rod 33 and the insertion hole 34 causes the brush holder 206 to lose its limit inside the mounting groove 205. At this point, the brush holder 206 can be pushed out of the mounting groove 205 to complete the disassembly operation. Then, a new one can be replaced. Through the cooperation of the above structure, the brush body 207 can be easily replaced after severe wear.
