Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator traction machine technology, specifically a household elevator traction machine. Background Technology
[0002] A traction machine is the power equipment of a home elevator, also known as an elevator main unit. Its function is to deliver and transmit power to make the elevator run. However, existing devices have certain drawbacks. For example, the elevator traction machine described in announcement number CN221853883U, which specifically relates to the field of traction machines, includes a machine body. The bottom of the machine body is fixed with a mounting plate, and a base plate is provided below the mounting plate. A traction sheave is rotatably installed at the middle position of one end of the machine body, and a dust cover is provided on the outside of the traction sheave. Sockets are provided on both sides of the machine body, and a limit component is installed at the middle position of the top of each socket.
[0003] The existing technology for buffering the above-mentioned device can achieve this during installation by using threaded components and gaskets. However, when the device is moved to the installation location, it may need to be moved up and down stairs. Some stairs do not allow the use of stair climbers. Therefore, workers will lay templates on the stair surface and move the device by dragging it. The friction between the device and the templates is large, which makes it inconvenient to move the device up and down the stairs. Utility Model Content
[0004] The purpose of this invention is to provide a traction machine for home elevators to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A home elevator traction machine includes a base plate, a traction motor fixedly connected to the upper surface of the base plate, a brake detachably connected to the upper surface of the base plate, a reduction gearbox fixedly connected to the upper surface of the base plate, a traction sheave fixedly connected to the output end of the reduction gearbox, an outer frame nested on the upper surface of the base plate, and a top plate snapped onto the upper surface of the outer frame.
[0007] The outer surface of the outer frame is rotatably connected to a locking mechanism, and the front surface of the outer frame is movably connected to a scraping mechanism.
[0008] Furthermore, mounting feet are fixedly connected to the side surface of the base plate near the four corners, and mounting plates are fixedly connected to the upper surface of the base plate near the four corners. The inner surface of the mounting plate is threaded with a first bolt, and the mounting plate is detachably connected to the outer frame through the first bolt.
[0009] Furthermore, the output end of the traction motor and the input end of the gearbox are fixedly connected.
[0010] Furthermore, a dustproof net is embedded and movably connected to the upper surface of the outer frame near the side surface, and a hanging ring is fixedly connected to the upper surface of the outer frame.
[0011] Furthermore, a side plate is fixedly connected to the lower surface of the top plate, and a fan is detachably connected to the inner surface of the side plate.
[0012] Furthermore, the locking mechanism includes a mounting bracket, a screw, a movable bracket, and a rotating sleeve. The mounting bracket is fixedly connected to the side surface of the outer frame, and there are two sets of mounting brackets. A connecting bracket is rotatably connected to the outer surface of the mounting bracket. An internal threaded cylinder is rotatably connected to the upper surface of one connecting bracket, and a guide cylinder is fixedly connected to the upper surface of the other connecting bracket. The screw is threadedly connected to the inside of the internal threaded cylinder. The movable bracket is embedded and rotatably connected to the inside of the guide cylinder. The movable bracket and the screw are fixedly connected. The rotating sleeve is nested and rotatably connected to the outer surface of the movable bracket.
[0013] Furthermore, the scraping mechanism includes a snap-fit seat, a T-shaped seat, and a scraping frame. The snap-fit seat is embedded and connected to the front surface of the outer frame. Two snap-fit plates are rotatably connected to the outer surface of the snap-fit seat, and a second bolt is threaded onto the front surface of the snap-fit plates. Snap-fit feet are fixedly connected to the front surface of the outer frame and the snap-fit plates at corresponding positions. The T-shaped seat is embedded and detachably connected to the lower surface of the snap-fit seat. A spring is nested and connected to the outer surface of the T-shaped seat. The scraping frame is nested and movably connected to the outer surface of the T-shaped seat, and the scraping frame is in contact with the spring. A collection cylinder is fixedly connected to the lower surface of the scraping frame.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. Manually flip the movable frame to make it contact the lower surface of the base plate. Then rotate the internal threaded cylinder in the opposite direction to make the movable frame contact the mounting feet. The mounting feet provide auxiliary limit for the movable frame. At this time, the top plate and the snap-fit dustproof net can be manually pulled out for easy cleaning of the heat dissipation components later. At the same time, the rotating sleeve contacts the ground, making it easy for the device to be dragged on the ground with the lifting ring. It is suitable for transporting devices when going up stairs indoors.
[0016] 2. Due to the influence of the spring, the scraper and the traction sheave come into contact, scraping off excess lubricant from the traction sheave. The lubricant then enters the collection drum along the scraper for collection. This prevents abnormal noise that may occur during elevator operation due to insufficient friction, which could seriously affect the safety performance of the elevator. It also prevents untreated lubricating oil from oxidizing and forming a hard shell, which would increase the difficulty of maintaining the traction sheave. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0024] Please see Figure 1-5 In this embodiment of the utility model, a traction machine for a home elevator includes a base plate 1, a traction motor 101 fixedly connected to the upper surface of the base plate 1, a brake 102 detachably connected to the upper surface of the base plate 1, a reduction gearbox 103 fixedly connected to the upper surface of the base plate 1, a traction wheel 104 fixedly connected to the output end of the reduction gearbox 103, an outer frame 2 nested on the upper surface of the base plate 1, and a top plate 4 snapped onto the upper surface of the outer frame 2.
[0025] The outer surface of the outer frame 2 is rotatably connected to a locking mechanism 3, and the front surface of the outer frame 2 is movably connected to a scraping mechanism 5.
[0026] Specifically, during heat dissipation, fan 402 allows outside air to pass through dust filter 201. The filtered air carries away the heat inside the outer frame 2, ensuring that the heat generated by the device can be dissipated to the outside. Lifting ring 202 assists in lifting the device, facilitating its loading and unloading. Movable frame 305 is located on the upper surface of top plate 4, providing auxiliary positioning for top plate 4. Lifting ring 202 contacts movable frame 305, limiting its position. Manually rotating the internal threaded cylinder 303 causes screw 304 to extend under the push of the thread, allowing movable frame 305 to extend along guide cylinder 307. Manually flipping movable frame 305 brings it into contact with the lower surface of bottom plate 1. Then, rotating the internal threaded cylinder 303 in the opposite direction... The movable frame 305 contacts the mounting feet 105, which assist in limiting the movable frame 305. At this time, the top plate 4 and the snap-fit dustproof net 201 can be manually pulled out, which is convenient for cleaning the heat dissipation components later. At the same time, the rotating sleeve 306 contacts the ground, which is convenient for the device to be dragged on the ground with the lifting ring 202. It is suitable for indoor transportation devices when going up stairs. The lower surface of the bottom plate 1 and the upper surface of the top plate 4 are consistent, and a groove is reserved for the rotating sleeve 306 to rotate. The scraping mechanism 5 scrapes off the excess lubricant on the traction wheel 104, and the lubricant enters the collection cylinder 505 along the scraping frame 504 for collection, so as to avoid abnormal noise that may be generated during the operation of the elevator due to insufficient friction.
[0027] Example 1
[0028] like Figure 1-5 As shown, mounting feet 105 are fixedly connected to the side surface of the base plate 1 near the four corners, and mounting plates 106 are fixedly connected to the upper surface of the base plate 1 near the four corners. The inner surface of the mounting plate 106 is threaded with a first bolt. The mounting plate 106 is detachably connected to the outer frame 2 through the first bolt. The output end of the traction motor 101 is fixedly connected to the input end of the gearbox 103.
[0029] In this embodiment, during use, the traction motor 101 drives the traction wheel 104 to rotate through the reduction gearbox 103, and the brake 102 applies the brake. This is prior art and will not be described in detail here. The base plate 1 can be installed by mounting feet 105 in conjunction with external threaded components.
[0030] like Figure 1-5 As shown, a dustproof net 201 is embedded and movably connected to the upper surface of the outer frame 2 near the side surface, a hanging ring 202 is fixedly connected to the upper surface of the outer frame 2, a side plate 401 is fixedly connected to the lower surface of the top plate 4, and a fan 402 is detachably connected to the inner surface of the side plate 401.
[0031] In this embodiment, when dissipating heat, the fan 402 allows the outside air to pass through the dustproof net 201. The filtered air carries away the heat inside the outer frame 2, ensuring that the heat generated by the device can be dissipated to the outside. The lifting ring 202 is used to assist in lifting the device, making it easy to load and unload the device.
[0032] Example 2
[0033] Based on Embodiment 1, in order to overcome the problems of inconvenience in transporting the device and inconvenience in cleaning up excess lubricant in Embodiment 1.
[0034] like Figure 1-5 As shown, the locking mechanism 3 includes a mounting bracket 301, a screw 304, a movable bracket 305, and a rotating sleeve 306. The mounting bracket 301 is fixedly connected to the side surface of the outer frame 2, and there are two sets of them. The outer surface of the mounting bracket 301 is rotatably connected to a connecting bracket 302. The upper surface of one connecting bracket 302 is rotatably connected to an internal threaded cylinder 303, and the upper surface of the other connecting bracket 302 is fixedly connected to a guide cylinder 307. The screw 304 is threadedly connected to the inside of the internal threaded cylinder 303. The movable bracket 305 is embedded and rotatably connected to the inside of the guide cylinder 307. The movable bracket 305 and the screw 304 are fixedly connected. The rotating sleeve 306 is nested and rotatably connected to the outer surface of the movable bracket 305.
[0035] In this embodiment, when the device is in Figure 1 In the shown state, the movable frame 305 is located on the upper surface of the top plate 4, providing auxiliary limiting for the top plate 4. The lifting ring 202 is in contact with the movable frame 305, limiting the movable frame 305. The internal threaded cylinder 303 is manually rotated, and the screw 304 extends under the push of the thread, causing the movable frame 305 to extend along the guide cylinder 307. The movable frame 305 is manually flipped so that it contacts the lower surface of the base plate 1. Then, the internal threaded cylinder 303 is rotated in the opposite direction so that the movable frame 305 contacts the mounting foot 105, which provides auxiliary limiting for the movable frame 305. At this time, the top plate 4 and the snap-fit dustproof net 201 can be manually pulled out for easy cleaning of the heat dissipation components later. At the same time, the rotating sleeve 306 contacts the ground, making it easy for the device to be dragged on the ground with the lifting ring 202. It is suitable for transporting devices when going up stairs indoors. The lower surface of the base plate 1 and the upper surface of the top plate 4 are consistent, and a groove is reserved for the rotation of the rotating sleeve 306.
[0036] like Figure 1-5As shown, the scraping mechanism 5 includes a snap-fit seat 502, a T-shaped seat 501, and a scraping frame 504. The snap-fit seat 502 is embedded and connected to the front surface of the outer frame 2. Two snap-fit plates 506 are rotatably connected to the outer surface of the snap-fit seat 502, and a second bolt is threaded onto the front surface of the snap-fit plate 506. Snap-fit feet are fixedly connected to the front surface of the outer frame 2 and the snap-fit plates 506 at corresponding positions. The T-shaped seat 501 is embedded and detachably connected to the lower surface of the snap-fit seat 502. A spring 503 is nested and connected to the outer surface of the T-shaped seat 501. The scraping frame 504 is nested and movably connected to the outer surface of the T-shaped seat 501, and the scraping frame 504 is in contact with the spring 503. A collection cylinder 505 is fixedly connected to the lower surface of the scraping frame 504.
[0037] In this embodiment, when removing excess lubricant, the snap-fit plate 506 and snap-fit foot engage and are fixed with the second bolt. Under the influence of the spring 503, the scraper 504 contacts the traction sheave 104, scraping off the excess lubricant on the traction sheave 104. The lubricant then enters the collection cylinder 505 along the scraper 504 for collection. This avoids the possibility of abnormal noise during elevator operation due to insufficient friction, which could seriously affect the safety performance of the elevator. It also avoids the problem that untreated lubricant may oxidize and form a hard shell, increasing the maintenance difficulty of the traction sheave 104.
