Description

Technical Field

[0001] The utility model relates to the technical field of construction elevators, in particular to a cable pulley guide device for an elevator. Background Art

[0002] Construction elevators are usually called construction lifts, but the definition of construction elevators is broader, and construction platforms also belong to the construction elevator series. A simple construction elevator is composed of several parts such as a car, a drive mechanism, a standard section, a wall attachment, a chassis, a fence, and an electrical system. It is a construction machine that is often used to carry people and goods in construction. A cage wire rack connected to the inside of the cage is set on one side of the outside of the elevator cage. The cable connected to the power supply at the bottom of the elevator enters the cage through the cage wire rack.

[0003] Prior art 201721765290.4 discloses a cable for a construction elevator, comprising a working body, the working body comprising a guide rail frame, a cage is mounted on the guide rail frame, the cage is slidably connected to the guide rail frame, a cable arm is arranged on the left side of the cage, a cable guide is arranged below the cable arm frame, a cable reel is arranged below the cable guide frame, a cable is wound around the cable reel, the cable connects the cable guide frame and the cable arm frame, handles are arranged on both sides of the cable reel, a connecting shaft is arranged in the middle of the handle, the connecting shaft and the handle are fixedly connected by bolts, a core wire is arranged in the middle of the cable, and the core wire The cable is spirally shaped, with an insulating layer wrapped around the outside of the core wire, an auxiliary material layer wrapped around the outside of the insulating layer, a sheath wrapped around the outside of the auxiliary material layer, an outer sheath wrapped around the outside of the sheath, the core wire also includes a ground core conductor, and the middle part of the cable contains a hemp rope; in the comparative document, when the cage descends, the cables will fall and accumulate.

[0016] The present invention is further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0017] A cable pulley guide device for an elevator includes fixed rods 3 arranged at intervals from top to bottom on the side of a guide frame 2. A plurality of fixed rods 3 are arranged on the side of the guide frame 2 from top to bottom, including the bottom and middle positions of the guide frame 2. Two slideways 4 are arranged in parallel between the fixed rods 3 located in the middle and the bottom of the guide frame 2. An intermediate wire take-up frame 13 is arranged in the middle of the side of the guide frame 2 and above the slideway 4. The intermediate wire take-up frame 13 and the slideway 4 are on the same side of the guide frame 2. A cable pulley is slidably connected to the slideway 4. The cable passes through the intermediate wire take-up frame 13, the cable pulley and the cage wire take-up frame 12 in sequence and enters the interior of the cage.

[0018] Furthermore, L-shaped windproof frames 5 with opposite ends are respectively provided at both ends of the fixed rod 3 on the opposite side of the cage 11. The two windproof frames 5 are respectively located on both sides of the running route of the cage wire take-up frame 12. Rubber strips 6 are relatively arranged on the adjacent ends of the limiters 5. The ends of the two rubber strips 6 are overlapped up and down. The rubber strips 6 and the windproof frames 5 are combined to limit the cable in the horizontal direction. During the lifting process of the cage 11, it is ensured that the cage wire take-up frame 12 can pass between the two windproof frames 5. The cage wire take-up frame 12 passes through the overlap of the two rubber strips 6. After the cage wire take-up frame 12 passes, the rubber strips 6 are reset, and the cable is always run in a specific space through the dense windproof frames 5.

[0019] Furthermore, cross bars 7 are arranged at intervals between the slideways 4 to enhance the stability of the slideways 4 .

[0020] Furthermore, the cable pulley includes a back plate 8 located on the side of the slide 4 close to the cage 11, and rollers 9 that are engaged and slidably connected to the slide 4 are respectively arranged at the four corners of the back plate 8 opposite to the slide 4. The rollers 9 make the cable pulley 10 run up and down more smoothly and not easy to get off the slide. The middle part of the back plate 8 is rotatably connected to the cable pulley 10, and the cable pulley 10 is made of nylon, which is less likely to damage the cable. A protective shell 1 is provided on the back plate 8 and located on the outer periphery of the cable pulley 10. Cable openings are opened on both sides of the upper part of the protective shell 1. The cable is wound around the cable pulley 10 and the cable openings are passed through both sides. During operation, the weight of the cable pulley pulls the cable downward, and the cage 11 drives one end of the cable to move, thereby driving the cable pulley 10 and the back plate 8 to move up and down. This structure can prevent cables from accumulating.

[0021] The middle wire take-up frame 13 is installed in the middle part of the guide rail frame 2, and the cable extends upward along the bottom of the guide rail frame 2 through the middle wire take-up frame 13, so that the cage wire take-up frame 12 bears 50% of the weight at the same height to prevent the cage wire take-up frame 12 from being damaged. The cable passes through the middle wire take-up frame 13 downward, bypasses the cable pulley 10 upward, passes through the cage wire take-up frame 12 and enters the cage. During the movement of the cable, it is located in the space formed by the rubber strip 6 and the windproof frame 5. The cage runs through the cable to drive the cable pulley 10 and the back plate 8 to move up and down along the slide 4. No matter what position the cage is in, the cables will not be piled up.

[0022] The above description is only a preferred feasible embodiment of the present utility model, and does not limit the scope of rights of the present utility model. All equivalent changes made using the contents of the present utility model specification and its drawings are included in the scope of rights of the present utility model.
