Description

Technical Field

[0001] The utility model relates to the field of electrical accessories, in particular to an aluminum alloy auxiliary rail for a platform elevator. Background Art

[0002] The elevator auxiliary rail is one of the important parts of the elevator operation. As a balance rail, the elevator auxiliary rail is mainly responsible for bearing part of the weight and balancing the elevator. The auxiliary rail is used in conjunction with the main rail to ensure the safety and smooth operation of the elevator. Aluminum alloy has good strength and light weight, so the elevator auxiliary rail is often made of aluminum alloy, which can reduce the burden on the elevator guide rail structure.

[0003] At present, there is a Chinese patent with a publication number of CN217759794U, which discloses a compact household elevator shaft frame, including an aluminum alloy frame, which is composed of a front side plate, a left side plate (1), a right side plate (2) and a rear side plate (3). A plurality of module brackets are arranged in the aluminum alloy frame, which are U-shaped when viewed from above, and the plurality of module brackets are distributed from top to bottom; the module brackets include a crossbeam (4) fixed to the rear side plate (3), and side beams (5) are arranged at both ends of the crossbeam (4), one of the side beams (5) is fixed to the left side plate (1), and the other side beam (5) is fixed to the right side plate (2); a secondary guide rail (6) is arranged on the inner side of the rear side plate (3), and a plurality of crossbeams (4) are fixed to the secondary guide rail (6); a main rail (7) is arranged on the inner side of the left side plate (1) and the inner side of the right side plate (2), and the main rail (7) is fixed to the corresponding plurality of side beams (5).

[0004] Disclosed therein is a secondary guide rail with a T-shaped cross-section, in which the rear side plates press the two wings of the secondary guide rail to fix them, so the two wings of the secondary guide rail are where the force is concentrated. In the case of long-term operation, the secondary guide rail is easily deformed or damaged due to the long-term force concentration there.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] Aiming at the deficiencies of the prior art, the utility model discloses an aluminum alloy auxiliary rail for a platform elevator.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A platform elevator aluminum alloy auxiliary rail comprises a guide rail body, a guide rail bracket and a guide shoe, wherein the guide rail body is detachably connected to the guide rail bracket, and the guide shoe is slidably arranged on the guide rail body; a wing plate is arranged on the guide rail body, the wing plate is arranged on one side of the guide rail body, and the guide rail body and the wing plate are perpendicular to each other, and a first extension part, a second extension part and a third extension part are arranged on the wing plate.

[0009] Furthermore, the first extension portion and the third extension portion are respectively arranged at the left and right ends of the wing plate, the second extension portion is arranged in the middle of the wing plate, and the first extension portion, the second extension portion and the third extension portion are perpendicular to the wing plate.

[0010] Furthermore, ribs are provided at the tail ends of the first extension portion, the second extension portion and the third extension portion.

[0011] Furthermore, the first extension portion, the second extension portion and the wing plate form a first screw slot.

[0012] Furthermore, the second extension portion, the third extension portion and the wing plate form a second screw slot.

[0013] Furthermore, the guide rail bracket is provided with a plurality of pairs of fixing screws, and in each pair of fixing screws, one fixing screw is clamped in the first screw sliding groove, and the other fixing screw is clamped in the second screw sliding groove.

[0014] Furthermore, a first guide rail working surface and a second guide rail working surface are respectively arranged on the left and right sides of the guide rail body, and a clamping portion is arranged in the guide shoe, and two ends of the clamping portion respectively contact the first guide rail working surface and the second guide rail working surface.

[0015] Furthermore, a third guide rail working surface is arranged on the guide rail body, and the third guide rail working surface is located on the side away from the wing plate. A pulley is rotatably arranged in the guide shoe, and the pulley is in contact with the third guide rail working surface.

[0016] Furthermore, a positioning hole is formed on the guide rail body.

[0017] The beneficial effects of the utility model are as follows:

[0018] 1. The first extension part, the second extension part and the third extension part on the wing plate are used as three supporting points to share the load on the wing plate, avoid excessive stress on a single structural component, avoid easy bending or damage of the structural component, and improve the stability of the auxiliary rail structure.

[0019] 2. The first screw slot and the second screw slot are used to accommodate the fixing screws. The ribs of the first extension part, the second extension part and the third extension part block the ends of the fixing screws to prevent the fixing screws from accidentally falling out, and also limit the installation position of the fixing screws, thereby improving the installation accuracy.
