Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a protective structure for the steel wire rope of an elevator traction machine. Background Technology

[0002] The elevator traction machine is a key component in an elevator system used to drive the car's vertical movement. It converts the rotational motion of the electric motor into the vertical motion of the car through the friction between the wire rope and the traction sheave. The traction machine is typically installed at the top of the elevator shaft and is a core component of elevator operation. A protective cover between the traction sheave and the guide sheave protects the wire rope from external environmental influences.

[0003] Chinese Patent CN212953740U discloses an elevator with a retractable protective cover. The elevator includes an elevator car, with a traction machine and a machine room guide wheel mounted on top of the car. A steel wire rope passes sequentially around the traction machine and the machine room guide wheel. A protective cover is installed on the steel wire rope between the traction machine and the machine room guide wheel. The protective cover includes an upper protective cover and a lower protective cover that are nested together. A groove is formed in the overlapping portion of the upper and lower protective covers, and a locking bolt is slidably connected within the groove. The traction machine is mounted on a load-bearing beam via a traction machine base. The protective cover is fixedly connected to the traction machine base via a cover fixing plate. This utility model replaces the existing one-piece protective cover with a separate retractable one, which is universal regardless of the traction machine's wrap angle or the length of the steel wire rope's inclination. Furthermore, spare parts can be mass-produced, saving labor time.

[0004] However, the above-disclosed technical solutions have the following shortcomings: different traction sheaves and guide sheaves have different axial lengths (for example, the axial lengths of traction sheaves that simultaneously pull 4 steel wire ropes and 6 steel wire ropes are different), the width of the protective cover cannot be adjusted, it is difficult to adapt to traction sheaves and guide sheaves with different axial lengths, and usually a special protective cover is required. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that the protection of wire ropes on traction sheaves with different axial lengths cannot be adapted to, and to propose a wire rope protection structure for elevator traction machines.

[0006] The technical solution of this utility model: a protective structure for the steel wire rope of an elevator traction machine, comprising:

[0007] The traction machine base is on which the traction machine and guide wheel are mounted, and a steel wire rope drives between the traction wheel and the guide wheel of the traction machine.

[0008] The enclosed box has openings at both the top and bottom. The enclosed box can extend longitudinally to change its longitudinal dimensions. The enclosed box is located between the traction sheave and the guide sheave, and the wire rope passes through the enclosed box.

[0014] Preferably, baffles are provided on both the upper and lower edges of the second half of the box, and the two baffles contact the upper and lower ends of the first half of the box, respectively.

[0015] Preferably, guide rails are provided on the upper inclined surfaces of both the first and second half-boxes. The guide rails are located on both sides of the enclosed box. Multiple guide grooves are provided at equal intervals at the bottom of the upper extension plate and the lower extension plate. The guide rails and one of the guide grooves cooperate to slide.

[0016] Preferably, multiple threaded holes are provided at equal intervals at the bottom of the upper extension plate and the top of the lower extension plate. Locking bolts are fitted on the threaded holes, and the ends of the locking bolts abut against the first half of the box or the second half of the box.

Then, according to the required longitudinal dimension, the bolts are screwed into the appropriate countersunk holes and through holes and locked with nuts. At this time, the first half of the box and the second half of the box are combined to form a closed box. The closed box is fixed on the traction machine base by the mounting bracket. Then, the upper extension plate and the lower extension plate are slid to the required position and fixed by locking bolts.

[0026] The traction machine base 1 is equipped with a traction machine and a guide wheel 3. A steel wire rope 4 is driven between the traction wheel 2 and the guide wheel 3 of the traction machine. The traction machine is existing technology, and its output end can be connected to the traction wheel 2. Since the traction machine is not the object of protection of this application, the traction machine is not described in detail and is not shown in the figure.

[0027] The enclosed box has openings at both the top and bottom. The enclosed box can extend longitudinally to change its longitudinal dimensions. The enclosed box is located between the traction sheave 2 and the guide sheave 3. The steel wire rope 4 passes through the enclosed box.

[0028] The upper extension plate 12 is slidably mounted on the inclined surface of the upper side of the closed box;

[0029] The lower extension plate 13 is slidably disposed on the inclined surface on the upper side of the closed box, and the lower extension plate 13 is located below the upper extension plate 12;

[0030] And mounting bracket 17, which is connected to the outer wall of the enclosed box and also to the traction machine base 1.

[0033] The enclosed box includes a first half-box 5 and a second half-box 6. Both the first half-box 5 and the second half-box 6 have openings on their longitudinally opposite sides. The second half-box 6 is inserted into the first half-box 5 and the two are detachably connected. The longitudinal dimensions of the enclosed box can be adjusted by changing the insertion length of the second half-box 6 to adapt to different usage scenarios.

[0034] Example 3

[0035] like Figures 2-4 As shown, the present invention proposes an elevator traction machine wire rope protection structure. Compared with Embodiment 1, this embodiment details the structural details of the enclosed box.
