[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. Example 1

[0026] Reference Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is an electric hoist wire rope protection device, comprising:

[0027] The isolation seat 1 includes a bottom plate 11, an end plate 12 and a side plate 13. The bottom plate 11 is a rectangular plate with V-shaped tips at both ends. A through hole 14 is vertically opened in the middle of the bottom plate 11; the end plate 12 is a V-shaped plate that matches the shape of the V-shaped tip. Two end plates 12 are provided and are respectively attached to the edge positions of the two V-shaped tips and vertically connected to the bottom plate 11; two side plates 13 are provided. The two side plates 13 are respectively attached to the two side edges of the bottom plate 11 and vertically connected thereto, and the two ends of the side plates 13 are respectively connected to the two end plates 12;

[0028] Two connecting arms 2 are provided. The two connecting arms 2 are symmetrically connected to the bottom plate 11 and located between the two side plates 13 .

[0029] Specifically, the bottom plate 11, the end plate 12 and the side plate 13 form a trough structure with pointed ends (i.e., the isolation seat 1). The isolation seat 1 is connected to the electric hoist A through two connecting arms 2, and the isolation seat 1 is located between two rubber isolation belts B installed on the walkway or beam and abutted against each other. The hook and wire rope C of the electric hoist extend downward through the through hole 14 on the bottom plate 11. The isolation seat 1 can separate the wire rope from the rubber isolation belt, thereby avoiding direct contact and friction between the wire rope and the rubber isolation belt, and improving the service life of the wire rope; at the same time, the pointed structures at both ends of the isolation seat 1 can play a guiding role during the movement of the electric hoist, pushing the rubber isolation belt to its two sides, thereby ensuring that the electric hoist can move stably and accurately without affecting the separation effect of the rubber isolation belt.

[0030] This utility model provides an electric hoist wire rope protection device that, without affecting the original separating function of the rubber isolation belt (which separates the corrosive working environment below from the electric hoist above), can separate the electric hoist wire rope from the rubber isolation belt, preventing the wire rope from direct contact and friction with the rubber isolation belt, thereby increasing the service life of the wire rope and reducing the frequency and cost of maintenance. It also acts as a position limiter for the wire rope, reducing its shaking during the operation of the electric hoist and improving safety. The entire protection device has a simple structure, is easy to install and maintain, and is highly practical.

[0031] Furthermore, two cover plates 15 are provided. The two cover plates 15 are respectively connected perpendicularly to the ends of the two end plates 12 away from the bottom plate 11. The ends of the two cover plates 15 away from the end plates 12 respectively extend toward the two connecting arms 2 and abut against the connecting arms 2. Specifically, the cover plates 15 are respectively connected to the end plates 12 and the side plates 13, and can provide a certain degree of support and limit the connecting arms 2, thereby improving the stability and strength of the entire structure.

[0032] Furthermore, two support plates 16 are vertically provided on the bottom plate 11 and are respectively located between the adjacent end plates 12 and the connecting arms 2 . The two ends of the support plates 16 are respectively connected to the end plates 12 and the connecting arms 2 .

[0033] Furthermore, one end of the connecting arm 2 is vertically connected to the bottom plate 11 near the V-shaped tip, and the other end is provided with a plurality of connecting holes, each of which is provided with a connecting bolt.

[0034] Furthermore, the width of the connecting arm 2 matches the spacing between the two side plates 13. The two side plates 13 can limit and support the connecting arm 2, and the connecting arm 2 can also support the two side plates 13.

[0035] Furthermore, the connecting arm 2 is made of channel steel, which is an existing product, thus eliminating the need for product design and production, and is low in price and easy to purchase.

[0036] Furthermore, the edges corresponding to the V-shaped angles of the end plate 12 are rounded. The rounded corners can play a good guiding role in the process of the end plate 12 pushing the rubber isolation belt away, and can also reduce the friction between the end plate 12 and the rubber isolation belt, which is beneficial to improving the service life of the rubber isolation belt and the end plate 12.

[0037] Furthermore, a plurality of rubber strips extending toward the center of the through hole 14 are provided on the inner wall of the through hole 14. Specifically, the rubber strips can block the gap between the through hole 14 and the steel wire rope passing through the through hole 14, and to a certain extent, can also play a role in isolating the corrosive environment below from the electric hoist, further reducing the corrosion of the electric hoist by the corrosive working environment and increasing the service life of the equipment.

[0038] Furthermore, the through hole 14 is a waist-shaped hole. Specifically, the through hole 14 can be set to a waist-shaped hole or a round hole according to actual working conditions. Example 2

[0039] The utility model also discloses an electric hoist, comprising the electric hoist wire rope protection device as described in the first embodiment.

[0040] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
