Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and more specifically, to an elevator traction device. Background Technology

[0002] In elevator systems, the traction sheave, as one of the core components, plays a vital role in achieving the lifting and lowering of the car through the friction between the steel wire rope and components such as the car and counterweight. However, in actual use, the traction sheave is exposed to the complex environment of the elevator shaft for a long time, facing many potential risks.

[0003] Because the traction sheave rotates during elevator operation, if operators or maintenance personnel accidentally come into contact with the rotating sheave while performing maintenance or repair work, it could potentially lead to a serious safety accident and threaten their personal safety. Therefore, we have made improvements and proposed an elevator traction device. Utility Model Content

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] For an example, please refer to... Figures 1-5 An elevator traction device includes two frames 1, with a traction machine 2 installed between the tops of the two frames 1. The device is characterized by a protective mechanism 3 provided between the two frames 1. The protective mechanism 3 includes a support member disposed between the two frames 1, and a protective cover 301 connected to the support member. The protective cover 301 covers the traction sheave of the traction machine 2. The protective cover 301 isolates the rotating traction sheave of the traction machine 2 from the outside environment, reducing the risk of accidental contact by operators or maintenance personnel when working near the traction sheave, providing reliable protection for personnel safety, and reducing injuries caused by accidental contact.

[0028] The protective cover 301 has an observation port 302, and a protective net 303 is fixedly installed inside the observation port 302. The protective net 303 can protect the observation port 302, and the operating status of the traction sheave can be observed through the observation port 302 and the protective net 303.

[0029] Furthermore, the side of the protective cover 301 away from the observation port 302 and the bottom surface are both open, and the open design avoids interference between the wire rope and the protective cover 301.

[0030] Furthermore, the support includes a support plate 307 disposed between the tops of the two frames 1. Connecting rods 306 are fixedly installed on both sides of the top of the support plate 307. Sleeves 304 are fitted on the outer surfaces of the two connecting rods 306. The two sleeves 304 are fixedly connected to the protective cover 301. The support plate 307, connecting rods 306 and sleeves 304 cooperate with each other to support the protective cover 301.

[0031] Furthermore, a notch 305 is provided on the sleeve 304, and a groove 308 corresponding to the notch 305 is provided on the connecting rod 306; a limiting member is provided between the two sleeves 304, and the limiting member is connected to the notch 305 and the groove 308. The limiting member can limit the sleeve 304 through the groove 308 and the notch 305, thereby limiting the protective cover 301.

[0032] Furthermore, the limiting component includes a limiting rod 309, which is inserted between the groove 308 and the notch 305. The insertion of the limiting rod 309 into the groove 308 and the notch 305 can restrict the movement of the sleeve 304, thereby preventing the sleeve 304 from separating from the connecting rod 306 and fixing the protective cover 301.

[0033] Furthermore, a hinge is provided between one end of the limiting rod 309 and one of the sleeves 304. The hinge allows the limiting rod 309 to rotate. During the rotation, the limiting rod 309 connects with or separates from the groove 308 and the notch 305.

[0034] Furthermore, a fixing member is provided between the end of the limiting rod 309 away from the hinge and the protective cover 301. The fixing member is used to fix the limiting rod 309 to improve the stability of the limiting rod 309 in contact with the notch 305 and the groove 308.

[0035] Furthermore, the fastener includes a hand-tightening bolt 310 threadedly connected to the limiting rod 309. One end of the hand-tightening bolt 310 is threadedly connected to an internally threaded tube 311, and the internally threaded tube 311 is fixedly connected to the protective cover 301. The internally threaded tube 311 and the hand-tightening bolt 310 cooperate with each other to fix the limiting rod 309.

[0036] Furthermore, mounting holes are provided on the support plate 307, and the support plate 307 is connected to the frame 1 by bolts.

[0037] When the protective cover 301 needs to be removed, rotate the hand-tightening bolt 310 to separate it from the internal threaded tube 311, rotate the limiting rod 309 to separate it from the notch 305 and the groove 308, and pull the protective cover 301 upwards to separate the sleeve 304 from the connecting rod 306 to remove the protective cover 301. When installing, insert the notch 305 and the connecting rod 306 together, then rotate the limiting rod 309 to insert it into the notch 305 and the groove 308, and rotate the hand-tightening bolt 310 to connect it to the internal threaded tube 311.
