Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to elevator equipment, and specifically to a lifting limit mechanism for the trailing cable of an inclined elevator. Background Technique

[0002] With the development of society and the improvement of people's living standards, inclined elevators are widely used in scenic spots. Inclined elevators are mainly used to complete the lifting of some sloping trajectories, which are more labor-saving and energy-saving than traction elevators for vertical transportation, and have a compact structure, safety and reliability.

[0003] However, due to its particularity, during the operation of an inclined elevator, the trailing cable of the inclined elevator needs to be restricted to walk within a specific path to achieve the safe operation of the inclined elevator. During the operation of existing inclined elevators, there are problems such as the drooping and swaying of the traction steel wire rope and the trailing cable, and the trailing cable is prone to severe wear and has a short service life. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a lifting limit mechanism for the trailing cable of an inclined elevator, which overcomes the deficiencies of the prior art and can effectively avoid the problems of drooping and swaying of the trailing cable during the operation of the inclined elevator, ensuring the stable operation of the elevator.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0006] A lifting limit mechanism for the trailing cable of an inclined elevator, including a fixed frame, guide shoes are fixedly installed on both sides of the fixed frame, the fixed frame is slidably connected to the elevator car guide rail through the guide shoes, a trailing cable pulley is installed on the fixed frame, and the trailing cable is wound around the outer edge of the trailing cable pulley.

[0007] Preferably, placing grooves are provided at both ends of the fixed frame, and counterweight blocks are installed in the placing grooves.

[0008] Preferably, it further includes multiple groups of trailing cable blockers, which are vertically and equidistantly arranged between the elevator car guide rails.

[0009] Preferably, four guide shoes are provided, and the four guide shoes are respectively installed above and below the left and right sides of the fixed frame.

[0010] The utility model provides a lifting limiting mechanism for a diagonal elevator trailing cable, which has the following beneficial effects: through the sliding connection between the guide shoe and the elevator car guide rail, the fixed frame can slide up and down along the elevator car guide rail; and because the trailing cable is wound around the trailing cable pulley, and the trailing cable pulley is installed on the fixed frame, it is ensured that the trailing cable can move up and down with the fixed frame within the limiting position. The problems of drooping and swaying of the trailing cable during the operation of the diagonal elevator are avoided, and the stable operation of the elevator is ensured. When there is a deviation between the guide shoe and the trailing cable pulley, a counterweight can be installed at the other end to achieve the horizontal state of the entire fixed frame; and then the stability of the entire fixed frame sliding up and down along the elevator car guide rail can be effectively ensured.

[0016] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the drawings in the present utility model.

[0017] Embodiment 1, as Figures 1 to 2 shown, a lifting limiting mechanism for a diagonal elevator trailing cable includes a fixed frame 1. Guide shoes 2 are fixedly installed on the left and right sides of the fixed frame 1. The fixed frame 1 is slidably connected to the elevator car guide rail 3 through the guide shoes 2. A trailing cable pulley 4 is installed on the fixed frame 1 through a mounting shaft. Specifically, a strip-shaped hollow hole can be opened on the surface of the fixed frame 1, and a mounting shaft is installed between the long side surfaces on the front and rear sides of the hollow hole through bearings. Then, the central hole of the trailing cable pulley 4 is connected to the mounting shaft through a key, so that the radial surface of the trailing cable pulley 4 is perpendicular to the surface of the fixed frame 1; the trailing cable 5 is wound around the outer edge of the trailing cable pulley 4.

[0018] Working principle:

[0019] During use, the entire fixing frame 1 can slide up and down along the elevator car guide rail 3 through the sliding connection between the guide shoes 2 on both sides and the elevator car guide rail 3; at this time, because the accompanying cable 5 is wound around the accompanying cable hanging wheel 4, and because the accompanying cable hanging wheel 4 is installed on the fixing frame 1, it is ensured that the accompanying cable 5 can move up and down within the restricted position following the fixing frame 1. The problem of sagging and shaking of the accompanying cable during the operation of the inclined elevator is avoided, and the stable operation of the elevator is ensured.

[0020] Embodiment 2, as a further preferred solution of embodiment 1, both ends of the fixing frame 1 are provided with placement grooves, and counterweights 6 are installed in the placement grooves. By providing placement grooves on the fixing frame 1 for placing the counterweights 6, when the guide shoe 2 and the accompanying cable hoist wheel 4 are offset, the counterweight can be installed at the other end to achieve the horizontal state of the entire fixing frame 1; and then the stability of the entire fixing frame 1 when sliding up and down along the elevator car guide rail 3 can be effectively guaranteed.

[0021] Embodiment 3, as a further preferred solution of embodiment 1, further comprises a plurality of groups of accompanying cable barriers 7, and the accompanying cable barriers 7 are vertically and equidistantly arranged between the elevator car guide rails 3. Thus, the accompanying cable barriers 7 can support the accompanying cable 5, prevent the accompanying cable 5 from sagging, and then prevent the accompanying cable 5 from having abrasion problems.

[0022] Embodiment 4, as a further preferred embodiment of embodiment 1, four guide shoes 2 are provided, and the four guide shoes 2 are respectively installed above and below the left and right sides of the fixing frame 1. Through the joint action of the four guide shoes 2, the stability of the fixing frame 1 when sliding up and down along the elevator car guide rail 3 can be effectively guaranteed.
