[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, this utility model provides a construction elevator cable limiting bracket, including a mounting frame 10. The mounting frame 10 includes an angle steel 11, and a steel hoop 12 is provided on one side of the angle steel 11. Two limiting frames 20 are provided on the inner side of the mounting frame 10. The two limiting frames 20 are symmetrically arranged together to form a limiting clamp for the construction elevator cable. The limiting frame 20 includes a shaft 23, a movable seat 21, and a connecting frame 22. One end of the shaft 23 is fixedly mounted on the mounting frame 10, the movable seat 21 is movably mounted on the other end of the shaft 23, and the connecting frame 22 is fixedly mounted on the end of the movable seat 21 away from the shaft 23. The upper and lower ends of the connecting frame 22 are provided with cable guide wheels 2205. The construction elevator cable is clamped in the middle by the cable guide wheels 2205 on the two opposite connecting frames 22.

[0021] like Figure 2 As shown, the connecting frame 22 includes two symmetrically arranged wing plates 2201, and several tie rods 2203 are arranged between the wing plates 2201. The two ends of the two wing plates 2201 on opposite sides are connected by bolts, and cable guide wheels 2205 are movably arranged on the bolts.

[0022] The center of the wire wheel 2205 is concave semicircular arc in this embodiment, and the two wire wheels 2205 can better fix the construction elevator cable when clamping the construction elevator cable in the middle.

[0023] As a preferred embodiment, the material of the wire wheel 2205 is selected to be a laminated rubber material, which ensures that the current will not pass through the wire wheel 2205 to the mounting frame 10 and then to the construction elevator due to damage of the cable, thereby causing an electric shock accident.

[0024] In this embodiment, the outer side of the two movable seats 21 is provided with a fixing hole on the opposite side, and the middle side of the two connecting frames 22 is provided with a mounting hole 2202, and the mounting hole 2202 and the fixing hole are fixed together by bolts.

[0025] As shown in Figure 3 The two movable seats 21 are provided with a movable slot 2101 on the opposite side, and a movable hole 2102 penetrating the movable seat 21 is provided at the center of the bottom wall along the movable slot 2101. The shaft 23 includes a connecting shaft 2302 and a sliding block 2301 provided at one end of the connecting shaft 2302. The sliding block 2301 is slidingly arranged in the movable slot 2101, and the connecting shaft 2302 penetrates the movable hole 2102 and is fixed to the inner side of the mounting frame 10. A contact spring 24 is arranged between the sliding block 2301 and the movable slot 2101. The limiting clamp formed by the two limiting frames 20 clamps the construction elevator cable, thereby ensuring that the construction elevator cable will not rub against the steel hoop 12 due to the lifting of the elevator. The two connecting frames 22 are brought into contact by the action of the contact spring 24. This elastic clamping method is suitable for cables of different models and different thicknesses, and has a wider application range.

[0026] It should be noted that when the two limiting frames 20 are brought into contact by the elastic force of the contact spring 24, the sliding block 2301 moves within the range of the movable slot 2101.

[0027] As a preferred embodiment, a cable cleaning assembly is arranged between the two limiting frames 20. The cable cleaning assembly includes a semicircular barrel arranged at the middle of the opposite side of the two connecting frames 22. The inner side wall of the semicircular barrel is provided with bristles. When the two limiting frames 20 clamp the construction elevator cable, the two semicircular barrels also wrap the cable inside. With the up and down movement of the construction elevator, the surface of the cable is cleaned, thereby ensuring the smooth surface of the cable, so that the friction between the wire wheel 2205 and the cable will not increase due to long-term use, thereby increasing the stability of the operation.

[0028] Specifically, the working principle of the construction elevator cable limiting frame: the cable of the construction elevator is arranged between the two limiting frames 20, at this time the two movable seats 21 are moved towards each other under the elastic force of the contact springs 24, thereby driving the connecting frame 22, and the two wire wheels 2205 on the connecting frame 22 fix the cable in the concave semicircle, at this time the cable is clamped, in the process of moving up and down the construction elevator, the cable cleaning assembly cleans the surface of the cable, ensuring that the surface is clean, the limiting frame 20 ensures that the cable does not rub with any position of the mounting frame 10 during operation, reducing the possibility of damage, through the above structure, the problem that the cable surface is worn due to the continuous friction of the cable in the steel hoop 12 with the frequent lifting of the construction elevator in the prior art is solved, which not only affects the service life, but also increases the risk of electric shock.

[0029] The above has further described the utility model with specific embodiments, but it should be understood that the specific description here should not be understood as limiting the essence and scope of the utility model, and various modifications made by those skilled in the art after reading the above embodiments are within the scope of the utility model.
