Description

Technical Field

[0001] The utility model relates to the field of elevators, in particular to a traction sheave groove repairing device for repairing wheel groove defects in an elevator traction sheave. Background Art

[0002] At present, most vertical elevators in my country are suspended by steel wire ropes, and rely on the friction between the steel wire ropes and the traction sheave to drive the elevator up and down. This driving method will cause wear on the traction sheave.

[0003] However, due to the large difference in wire rope tension, improper placement of the wire rope by the installation operator, mismatch between the wire rope and the traction sheave groove, normal wear of the traction sheave, etc., the wear of the traction sheave rope groove is often inconsistent, which will cause the elevator to shake when running up and down, affecting the passengers' elevator experience. If not handled in time, it will shorten the service life of the traction sheave and wire rope and increase the risk of failure.

[0004] Normally, any traction sheave with groove wear exceeding a specified threshold is removed from the elevator shaft, repaired, and then reinstalled. This troubleshooting process is time-consuming (typically at least two days). Furthermore, removing the traction machine from the elevator shaft requires specialized tooling and the coordination of multiple personnel, further increasing troubleshooting costs. Therefore, a traction sheave groove repair device that can address these issues is needed. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] An embodiment of a traction sheave groove repairing device of the utility model:

[0033] The specific structure of a traction sheave groove repairing device in this embodiment is as follows: Figures 1 to 7 As shown, it includes a frame 1, on which a transverse slide 2 extending laterally is fixed, and on which a transverse slider 3 with a dovetail-shaped assembly groove is installed. The transverse slider 3 can be guided and moved along the length direction of the transverse slide 2.

[0034] A longitudinally extending longitudinal slide 4 is secured to the transverse slide 3. A longitudinal slide 5 with a dovetail-shaped mounting slot is mounted on the longitudinal slide 4, allowing for guided movement along the length of the longitudinal slide 4. A tool holder 6 is secured to the longitudinal slide 5. One side of the tool holder 6 has an insertion slot 61 that fits the cross-sectional shape of the handle of a tool 7, allowing it to engage. The tool holder 6 has a tool-fixing hole 62 defined above the insertion slot 61, with a corresponding hole defined in the handle. After the tool 7 is inserted into the insertion slot 61 and adjusted in position, it is secured to the tool holder 6 via bolts.

[0035] The transverse slide 2 is provided with a transverse feed mechanism 8 for driving the transverse sliding block 3 to move transversely, and the longitudinal slide 4 is provided with a longitudinal feed mechanism 9 for driving the longitudinal sliding block 5 to move longitudinally.

[0036] The transverse feed mechanism 8 has the same structure as the longitudinal feed mechanism 9, and the transverse feed mechanism 8 will be used as an example to explain it in detail. The transverse feed mechanism 8 includes a screw 81, a handwheel 82, and a nut. The screw 81 is rotatably mounted on the transverse slide 2, and the handwheel 82 is coaxially fixed to the end of the screw 81 extending from the transverse slide 2. The screw 81 can be driven to rotate by the handwheel 82. The nut is threadedly connected to the screw 81 and is fixedly connected to the transverse slider 3. When the handwheel 82 is rotated, the nut will drive the transverse slider 3 to move transversely. Similarly, when the handwheel in the longitudinal feed mechanism 9 is rotated, the longitudinal slider 5 can also be driven to move longitudinally.

[0037] The frame 1 is welded together by a main plate 11, a first reinforcing rib 12, a second reinforcing rib 13, a side pressure block 14 and an integral plate 15. The cross-section of the main plate 11 is L-shaped and includes a web and a side plate. The side plate is located on the left side of the web and extends rearward. The side plate is provided with a threaded hole. The first reinforcing rib 12 is welded to the front side of the web, and two trapezoidal second reinforcing ribs 13 are welded between the upper end face of the first reinforcing rib 12 and the front end face of the web. The side pressure block 14 is welded to the right side face of the web and the front ends of the two are flush. The integral plate 15 is bolted to the main plate 11. After fixing, the upper end face of the integral plate 15 is aligned with the lower end face of the first reinforcing rib 12.

[0038] The right half of the integral plate 15 extends out of the main plate 11 and the first reinforcing rib 12 , and the shape of the extended portion matches the shape of the transverse slide 2 . The transverse slide 2 is fixed above the right half of the integral plate 15 by bolts.

[0039] The web is staggered with the first and second reinforcing ribs 12 and 13 to form multiple bolt holes. The web lower end of the main plate 11 is provided with two grooves 111 for avoiding the anchor bolts used for fixing the traction sheave.

[0040] The rear end of the side pressure block 14 extends backward from the web, so that it can cooperate with the right end limit stop of the traction wheel frame. At the same time, the side pressure block 14 is only set at the upper end of the web, and the leftward movement limit position of the transverse slide 2 and the transverse slider 3 that are staggered in height is not restricted, ensuring that the tool 7 can reach the leftmost rope groove. The side plate extending backward can cooperate with the left end limit stop of the traction wheel frame. Therefore, the side pressure block 14 and the side plate together form a transverse positioning structure. Through the transverse positioning structure, the repair device of the present invention can be just stuck on both sides of the traction wheel frame when in use, and the transverse positioning can be completed quickly and conveniently. Combined with the positioning between the brake mounting hole on the traction wheel frame and the fixing bolt hole on the main plate 11, the repair device of the present invention can be quickly and accurately positioned without the need for reciprocating leveling and positioning, shortening the equipment installation and commissioning cycle.

[0041] Of course, in other embodiments, the transverse positioning structure may also be integrally formed with the main plate 11 .

[0042] The side plate of the main body plate 11 is provided with three fixing bolt holes, namely fixing bolt hole 11-1, fixing bolt hole 2 11-2, and fixing bolt hole 3 11-3. The main body plate 11 is mounted on the brake mounting hole through these three fixing bolt holes.

[0043] In other embodiments, a hook portion may be fixed to the upper end of the web. The hook portion may be a hanging ring, a hook, or other structures that are convenient for hooking to transfer the spatial position of the utility model.

[0044] The process of using the utility model to repair a worn traction sheave is as follows:

[0045] First, remove the brake from the traction sheave frame. Next, secure the frame 1 to the traction sheave frame using the brake mounting holes on the traction sheave frame. Next, measure the wear of each rope groove on the traction sheave and determine the required turning distance based on the location of the most severe wear. Finally, adjust the corresponding rope groove of the tool 7 using the transverse feed mechanism 8, and the cutting distance using the longitudinal feed mechanism 9. By turning each rope groove one by one, the wear repair process is complete.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
