Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance technology, and more specifically, to an elevator traction steel wire rope oil cleaning device. Background Technology

[0002] Currently, the conventional maintenance method for traction wire ropes is for technicians to directly clean and lubricate the ropes with a brush while standing in the machine room. While this method is simple, it has the following drawbacks:

[0003] (1) Time-consuming and labor-intensive: With the increasing labor costs and the growing number of elevators, if technicians need to spend 2 to 3 hours cleaning and lubricating the traction steel wire rope for each elevator, the labor costs will undoubtedly increase significantly.

[0004] (2) Safety issues: Because the elevator traction steel wire rope is a moving part, when the maintenance is done manually, the standing time will be relatively long, which can easily lead to fatigue and relaxation; on the other hand, the traction machine and steel wire rope are constantly rotating, and if you are not careful, your hand may be pulled into the steel wire rope, causing injury to the technician and posing a hidden danger; in addition, hand cleaning and lubrication maintenance may cause oil to drip everywhere, and the dripping oil can easily splash onto the traction machine brake, which may cause safety hazards such as elevator slippage.

[0005] (3) When cleaning, lubricating and maintaining the elevator traction steel wire rope, the elevator cannot be operated with people due to safety concerns. If the maintenance time is too long, it will affect the residents' travel. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a device for cleaning oil stains on elevator traction steel wire ropes.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] An elevator traction steel wire rope oil stain cleaning device includes a cantilever detachably mounted on an I-beam in the elevator machine room, a support frame mounted on one end of the cantilever, and brushes and oil scrapers mounted on the support frame for scraping oil stains off the brushes. After the cantilever is installed, several parallel and spaced traction steel wire ropes pass through the interior of the support frame, and the brushes can abut against the outer wall of any of the traction steel wire ropes.

[0009] Furthermore, in this utility model, a belt conveyor mechanism is provided inside the aforementioned support frame. The belt conveyor mechanism includes two synchronous pulleys spaced apart inside the aforementioned support frame. The two synchronous pulleys are connected by an elastic synchronous belt.

[0010] Furthermore, in this utility model, the oil scraper includes a vertical plate disposed on the bearing frame and a plurality of scraping teeth disposed on one side of the vertical plate. When the synchronous belt is working, the brush can abut against any of the scraping teeth.

[0011] Furthermore, in this utility model, a collection groove is also provided on the above-mentioned support frame below the above-mentioned brush.

[0012] Furthermore, in this utility model, the aforementioned support frame is also provided with a tensioning device. When the brush bristles of the aforementioned brush are worn, the tensioning device ensures that the aforementioned brush always abuts against the outer wall of any of the aforementioned traction steel wire ropes.

[0013] Furthermore, in this utility model, the tensioning device includes two rotating shafts arranged parallel to each other on the bearing frame. Any of the rotating shafts is rotatably connected to the bearing frame. Both rotating shafts are located within the synchronous belt.

Detailed Implementation

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] An elevator traction steel wire rope oil stain cleaning device includes a cantilever 1 detachably mounted on an I-beam in the elevator machine room, a support frame 2 at one end of the cantilever 1, brushes 3 mounted on the support frame 2, and an oil scraper 4 for scraping oil stains off the brushes 3. In this embodiment, a strong magnetic chuck 9 is installed at the end of the cantilever 1 away from the support frame 2, fixing the cantilever 1 to the I-beam in the elevator machine room through magnetic attraction. In other embodiments of this embodiment, the cantilever 1 can also be fixed to the I-beam in the elevator machine room by a combination of bolts and flanges. After the cantilever 1 is installed, several parallel and spaced traction steel wire ropes 5 should all pass through the interior of the support frame 2, and the brushes 3 should be able to abut against the outer wall of any traction steel wire rope 5. The cantilever 1 can be designed as a telescopic structure to facilitate adjustment of the position of the support frame 2.

[0024] To facilitate the scraping of oil stains from the brush 3 by the scraper 4, a belt conveyor mechanism is also installed inside the support frame 2 in this embodiment. The belt conveyor mechanism includes two synchronous pulleys 601 spaced apart inside the support frame 2. The two synchronous pulleys 601 are connected by an elastic synchronous belt 602. Any synchronous pulley 601 is rotatably connected to the support frame 2, and the central axis of any synchronous pulley 601 is parallel to the central axis of any traction steel wire rope 5. The rotation of one of the synchronous pulleys 601 is driven by a motor. The brush 3 is mounted on the side wall of the synchronous belt 602 away from its own toothed layer. Meanwhile, the scraper 4 includes a vertical plate 401 mounted on the support frame 2 and several scraping teeth 402 mounted on one side of the vertical plate 401. Thus, when the scraper 4 needs to scrape the oil stains from the brush 3, the synchronous pulleys 601 rotate to drive the synchronous belt 602 to rotate, thus removing the oil stains from the brush 3. Figure 2 From the perspective of the brushes 3, when the brushes 3 move below the synchronous belt 602, the brushes 3 come into contact with the scraping teeth 402 one by one, and the scraping teeth 402 can scrape off some of the oil stains on the brushes 3.

[0025] Before the brush 3 cleans the surface of the traction wire rope 5, a cleaning fluid spraying device (not shown in the figure) is needed to spray the cleaning fluid onto the surface of the traction wire rope 5. The cleaning fluid spraying device can also be installed on the support frame 2. The structure and working principle of the cleaning fluid spraying device are existing technologies and will not be described in detail here. It can consist of a storage tank for storing cleaning fluid, a water pump for pumping the cleaning fluid from the storage tank, and a spray pipe. The spray pipe and the storage tank are connected by the water pump.

[0026] Meanwhile, in order to facilitate the collection of oil stains generated during the cleaning of the traction steel wire rope 5, a collection trough 7 for collecting oil stains is also installed on the bearing frame 2 below the brush 3 in this embodiment.

[0027] Since the traction steel wire rope 5 is usually made of multiple thin steel wires twisted together, the friction between the brush 3 and the traction steel wire rope 5 is relatively large. After prolonged contact with the traction steel wire rope 5, the brush 3 is prone to wear. When the end of the brush 3 that contacts the traction steel wire rope 5 is worn significantly, the brush 3 and the traction steel wire rope 5 cannot make complete contact, which reduces the cleaning effect of the brush 3. Therefore, to solve this problem, a tensioning device is also installed on the support frame 2 in this embodiment. When the brush bristles of the brush 3 are worn, the tensioning device ensures that the brush 3 always abuts against the outer wall of any traction steel wire rope 5.

[0028] Specifically, in this embodiment, the tensioning device includes two rotating shafts 801 installed parallel to each other on the support frame 2. Each rotating shaft 801 is rotatably connected to the support frame 2. Both rotating shafts 801 are located inside the synchronous belt 602. The central axis of each rotating shaft 801 is parallel to the central axis of each synchronous pulley 601. A swing arm 802 is installed at one end of each rotating shaft 801. The central axis of the swing arm 802 is not parallel to the central axis of the rotating shaft 801. A tensioning pulley 803 is rotatably installed at the end of the swing arm 802 away from the rotating shaft 801. The two tensioning pulleys 803 are symmetrically distributed about the symmetrical center lines of the two synchronous pulleys 601. The positions of the two tensioning pulleys 803 must ensure that each tensioning pulley 803 can abut against the toothed layer of the synchronous belt 602 near the traction steel wire rope 5. The rotation of each rotating shaft 801 can be driven by a motor.

[0029] When using this device to clean the traction steel wire rope 5, pre-set the operating parameters of the motors controlling the rotation of the two rotating shafts 801. Since the wear on the brush 3 is initially minimal, during this period, ensure that both tensioning wheels 803 are in contact with the toothed layer of the synchronous belt 602 near the traction steel wire rope 5. After a period of use, when wear appears on the ends of the brush 3, the motors controlling the rotation of the two rotating shafts 801 should operate according to the pre-set parameters, causing both rotating shafts 801 to rotate a certain angle. At this time, from... Figure 2 From the perspective of the rotating shaft 801, both rotating shafts 801 rotate. The left rotating shaft 801 causes the left tensioning wheel 803 to rotate clockwise around its own central axis by a certain angle, and the right rotating shaft 801 causes the right tensioning wheel 803 to rotate counterclockwise around its own central axis by a certain angle. This action of the two tensioning wheels 803 will cause the synchronous belt 602 located above the two tensioning wheels 803 to move upward by a certain distance, thus solving the above problem.

[0030] In other embodiments of this example, the structure of the swing arm 802 + tension wheel 803 can also be replaced by the eccentric wheel 10. (Refer to...) Figure 3 When installing the eccentric wheel 10, two eccentric wheels 10 are installed at one end of the two rotating shafts 801 respectively. During installation, the central axis of the eccentric wheel 10 is not collinear with the central axis of the corresponding rotating shaft 801. This can also solve the above problem if needed.

[0031] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
