Description

Technical Field

[0001] This utility model relates to the field of traction component repair technology, specifically an elevator mechanical traction component repair mechanism. Background Technology

[0002] In elevator operating systems, the traction shaft is the core transmission component connecting the traction sheave and the power source. Its surface precision and integrity directly affect the stability and safety of elevator operation. As the frequency of elevator use increases and the years increase, the traction shaft is prone to surface wear, scratches, deformation and other problems due to long-term friction, stress concentration, corrosion and other factors, which leads to a decrease in transmission efficiency, an increase in operating noise, and even safety hazards.

[0003] Currently, there are many limitations in the maintenance and repair methods for traction shafts. Traditional grinding methods mostly rely on manual hand tools, which not only makes it difficult to accurately control the grinding force and depth, easily resulting in insufficient surface precision of the shaft, but also leads to low efficiency and high labor intensity. Some companies use general-purpose machine tools for grinding, but due to the special structure of the traction shaft (such as shaft length, diameter specifications, keyway position, etc.), it is difficult to adapt them, requiring frequent adjustment of tooling fixtures, which increases maintenance costs and time. In addition, existing maintenance methods cannot achieve comprehensive inspection and repair of the traction shaft surface. For example, the grinding and repair effect on complex parts such as shaft shoulder transition fillets and keyway sidewalls is not good, which makes it difficult to meet the high precision requirements for safe elevator operation.

[0004] Therefore, developing a maintenance mechanism for elevator mechanical traction components that can efficiently, accurately, and comprehensively grind traction shafts has become a key issue that urgently needs to be addressed to improve the quality and efficiency of elevator maintenance and ensure the safe operation of elevators.

[0005] Chinese Patent (Authorization Announcement No. CN116395367A) discloses a maintenance mechanism for elevator mechanical traction parts, including a support platform body and a maintenance shell fixed to the top of the support platform body. The maintenance shell has a feeding port on one side, and the support platform body has a corresponding feeding mechanism inside. It also includes a moving plate inside the support platform body corresponding to the feeding mechanism, a vertical sleeve slidably connected to the outer walls of the moving plate, and a clamping mechanism inside the moving plate. This elevator mechanical traction parts maintenance mechanism, by setting up a feeding mechanism, allows the rotating cylinder, limiting plate, partition plate, and storage chamber to rotate when the feeding motor is turned on. The storage chamber can accommodate parts, thus enabling the parts to be separated. Furthermore, the parts can enter the top of the moving plate one by one under the action of the feeding mechanism, facilitating individual inspection and maintenance by staff and enhancing the efficiency of the equipment.

[0006] The above solution only separates the parts, but it cannot be used to polish the traction shaft when it is rusted and needs to be polished, which is a limitation. In order to solve the problem of not being able to polish it and the limitation, we propose an elevator mechanical traction parts repair mechanism. Utility Model Content

[0007] The purpose of this utility model is to provide a maintenance mechanism for elevator mechanical traction components to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An elevator mechanical traction component repair mechanism includes an installation cabinet. A display panel is fixedly installed on the outer wall of the installation cabinet. Two cabinet doors are rotatably connected to the outer wall of the installation cabinet. An installation base is fixedly connected to the bottom of the inner wall of the installation cabinet. A sliding plate is slidably connected to the upper end of the installation base. A grinding mechanism for grinding the traction shaft is fixedly installed between the sliding plate and the installation base. A limiting mechanism for fixing and limiting the traction shaft is also fixedly installed at the upper end of the installation base.

[0010] As a further aspect of this solution, the limiting mechanism includes a rotating disk, a first gear is fixedly connected to the outer wall of the rotating disk, the rotating disk is rotatably connected to the upper end of the mounting base via a rotating shaft, and multiple connecting columns with reset function are slidably connected to the end of the mounting base near the slide plate, and the connecting columns are fixedly connected to the rotating disk by a first spring.

[0011] As a further aspect of this solution, each of the connecting columns has a fixed abutment block at one end and an abutment wheel rotatably connected to the opposite end. The outer wall of the slide plate is rotatably connected to an abutment pipe, and the outer wall of each abutment wheel abuts against the inner wall of the abutment pipe.

[0012] As a further aspect of this solution, a telescopic tube is rotatably connected to the end of the abutment tube away from the slide plate, and the end of the telescopic tube away from the abutment tube is fixedly connected to the mounting base. A servo motor capable of driving the slide plate to move is fixedly installed on the upper end of the mounting base.

[0013] As a further aspect of this solution, the polishing mechanism includes multiple elastic telescopic rods, each of which is fixedly connected to the inner wall of the abutment tube. Each elastic telescopic rod has an abrasive block fixedly connected to its end away from the inner wall of the abutment tube. An arc plate is fixedly connected to the outer wall of the abrasive block. A toothed ring is fixedly connected to the outer wall of the abutment tube. A third gear with a reset function is rotatably connected to the outer wall of the slide plate. The third gear meshes with the toothed ring. A reel is fixedly connected to the end of the third gear away from the slide plate.

[0014] As a further aspect of this solution, a connecting rope is wound around the outer wall of the recycling reel, the free end of which is fixedly connected to the outer wall of the mounting base. A cooperating telescopic arm is fixedly connected to the end of the recycling reel away from the third gear. The end of the cooperating telescopic arm away from the recycling reel is rotatably connected to the outer wall of the mounting base. A second gear is welded and fixed to the end of the cooperating telescopic arm away from the recycling reel.

[0015] As a further aspect of this solution, the second gear meshes with the first gear.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When this utility model is in use, after the traction shaft is placed in place, the elastic structure automatically adapts to the shaft contour and applies stable pressure to ensure that the shaft is stable and does not shift during the grinding process. The servo motor-driven slide plate drives the abutment wheel and transmission components, so that the abrasive block can move along the shaft axis and also achieve circumferential rotation grinding through structures such as gears and gear rings, forming an all-round grinding path. In particular, during the reset process, the cooperation between the torsion spring and the rewind wheel allows the abrasive block to continue working when the slide plate returns, avoiding the waste of idle rotation during the round trip in the traditional grinding method, and significantly improving grinding efficiency and uniformity.

[0027] 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.

[0028] Example 1: Please refer to Figures 1-3 As shown in the embodiment of this utility model, an elevator mechanical traction accessory repair mechanism includes an installation cabinet 1. A display panel 3 is fixedly installed on the outer wall of the installation cabinet 1. Two cabinet doors 2 are rotatably connected to the outer wall of the installation cabinet 1 via a rotating shaft. The two cabinet doors 2 are symmetrically distributed on the outer wall of the installation cabinet 1. An installation base 4 is also fixedly connected to the bottom of the inner wall of the installation cabinet 1 by bolts. A sliding plate 8 is slidably connected to the upper end of the installation base 4. Specifically, two sliding strips 6 are fixedly connected to the upper end of the installation base 4 by bolts. The two sliding strips 6 are symmetrically distributed front and back on the upper end of the installation base 4. The sliding plate 8 is slidably connected to the outer wall of the two sliding strips 6. The outer wall of the sliding strips 6 and the interior of the sliding plate 8 are coated with lubricating oil. When the sliding plate 8 slides on the outer wall of the two sliding strips 6, the two sliding strips 6 can limit the sliding plate 8 and also have a guiding function, which improves the stability of the sliding plate 8 when it moves. The lubricating oil can also reduce the friction between the sliding plate 8 and the sliding strips 6, thereby extending the service life of the sliding strips 6 and the sliding plate 8.

[0029] A grinding mechanism 101 for grinding the traction shaft is fixedly installed between the slide plate 8 and the mounting base 4. A limiting mechanism 201 for fixing and limiting the traction shaft is also fixedly installed at the upper end of the mounting base 4.

[0030] Example 2: Please refer to Figures 2-8As shown, the limiting mechanism 201 includes a rotating disk 26, which is rotatably connected to the upper end of the mounting base 4 via a rotating shaft. The mounting base 4 is slidably connected to a plurality of connecting posts 12 with reset function at the end near the slide plate 8. The connecting posts 12 and the rotating disk 26 are fixedly connected by a first spring 14. Each connecting post 12 is fixedly connected to an abutment block 11 at the opposite end. The outer wall of the abutment block 11 is provided with an arc surface, which can better fit and polish the outer wall of the traction shaft. Each connecting post 12 is rotatably connected to an abutment wheel 13 via a rotating shaft at the opposite end. The outer wall of the slide plate 8 is rotatably connected to an abutment tube 15. The outer wall of each abutment wheel 13 abuts against the inner wall of the abutment tube 15. The end of the abutment tube 15 away from the slide plate 8 is rotatably connected to a telescopic tube 23. The end of the telescopic tube 23 away from the abutment tube 15 is fixedly connected to the mounting base 4.

[0031] A servo motor 5 that can drive the slide plate 8 to move is fixedly installed on the upper end of the mounting base 4. Specifically, the output end of the servo motor 5 is fixedly connected to a threaded rod 7 by bolts, and the outer wall of the threaded rod 7 is connected to the inner bolt of the slide plate 8.

[0032] The grinding mechanism 101 includes multiple elastic telescopic rods 16, each of which is fixedly connected to the inner wall of the abutment tube 15. The multiple elastic telescopic rods 16 are circumferentially distributed on the inner wall of the abutment tube 15. Each elastic telescopic rod 16 is fixedly connected to an abrasive block 18 at the end away from the inner wall of the abutment tube 15. The outer wall of the abrasive block 18 is fixedly connected to a curved plate 19. The curved plate 19 is curved. When the traction shaft abuts against the outer wall of the curved plate 19, the curved plate 19 can better push the abrasive block 18 open, so that the abrasive block 18 abuts against the outer wall of the traction shaft. The outer wall of the abutment tube 15 is fixedly connected to a toothed ring 17. The outer wall of the slide plate 8 is rotatably connected to a third gear 22 with a reset function through a rotating shaft. The third gear 22 meshes with the toothed ring 17. A reset torsion spring is engaged between the third gear 22 and the slide plate 8. The end of the third gear 22 away from the slide plate 8 is fixedly connected to a reel 27.

[0033] A connecting rope 25 is wound around the outer wall of the spool 27. The free end of the connecting rope 25 is fixedly connected to the outer wall of the mounting base 4. A matching telescopic arm 24 is fixedly connected to the end of the spool 27 away from the third gear 22. The end of the matching telescopic arm 24 away from the spool 27 is rotatably connected to the outer wall of the mounting base 4. A second gear 21 is welded and fixed to the end of the matching telescopic arm 24 away from the spool 27. A first gear 20 is fixedly connected to the outer wall of the rotating disc 26. The second gear 21 and the first gear 20 mesh with each other.

[0034] The working principle of this utility model is as follows:

[0035] When this utility model is in use, the traction shaft abuts against the outer wall of all the curved plates 19, all the elastic telescopic rods 16 will retract, and the abrasive block 18 will abut tightly against the outer wall of the traction shaft. At this time, when the traction shaft is located between all the abutting blocks 11, the servo motor 5 is started to drive the threaded rod 7 to rotate, the slide plate 8 will move under the action of the threaded rod 7, the slide plate 8 will drive the abutting pipe 15 to move, all the abutting wheels 13 will move along the inner wall of the abutting pipe 15, and at this time all the abutting wheels 13 will drive the connecting column 12 to move, and the connecting column 12 will drive the abutting block 11 to fix the outer wall of the traction shaft.

[0036] As the abutment tube 15 moves, it also stretches the telescopic tube 23, causing the abutment wheel 13 to abut against the inner wall of the telescopic tube 23. At this time, the retrieval reel 27 is pulled by the movement of the connecting rope 25, which drives the third gear 22 to rotate. The third gear 22 drives the gear ring 17 to rotate, which in turn drives the abutment tube 15 to rotate. The abutment tube 15 then drives all the elastic telescopic rods 16 to move, which in turn drives the abrasive block 18 to move. The abrasive block 18 then abuts against the outer wall of the traction shaft. According to the working principle described above, when the slide plate 8 resets and moves, the third gear 22 will rotate under the action of the reset torsion spring, and the connecting rope 25 will lose tension. The rotation of the third gear 22 will drive the retraction wheel 27 to rotate, and the retraction wheel 27 will retract the connecting rope 25. When the third gear 22 resets, it will also drive the abutment tube 15 to rotate, and the abutment tube 15 will drive all the abrasive blocks 18 to continue to polish the outer wall of the traction shaft. The slide plate 8 reciprocates back and forth to polish the outer wall of the traction shaft.

[0037] After polishing is complete, the slide plate 8 will drive the abutment tube 15 to reset, and the abutment wheel 13 will gradually move along the inner wall of the abutment tube 15. At this time, the abutment block 11 will reset and disengage from the outer wall of the traction shaft under the action of the first spring 14, so that the polished traction shaft can be taken away.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
