[0025] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] To make the purpose, technical scheme and advantages of the utility model clearer, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0027] Please refer to Figures 1-4 The utility model discloses an elevator rope head fixing device, which comprises:

[0028] The mounting plate 11 is provided with a stable support and fixing platform for other components.

[0029] The fixing assembly comprises a first side plate 21, a second side plate 22, a rotating hole 23 and an optical axis 24. The first side plate 21 is fixedly screwed on one side of the mounting plate 11. The second side plate 22 is fixedly screwed on the other side of the mounting plate 11. The rotating hole 23 is formed on one side of the outer surfaces of the first side plate 21 and the second side plate 22. The optical axis 24 is rotatably penetrated in the rotating hole 23.

[0030] The mounting plate 11 provides a stable support and fixing platform for other components. The first side plate 21 and the second side plate 22 provide a stable support frame for the rotating hole 23 and the optical axis 24. The rotating hole 23 provides an installation space for the optical axis 24, so that the optical axis 24 can rotate freely in the installation space.

[0031] One side of the mounting plate 11 is fixedly screwed with a guide rail 12. The two sides of the mounting plate 11 are fixedly provided with reinforcing supports 13, and the reinforcing supports 13 are fixedly screwed with the first side plate 21. One side of the first side plate 21 and the second side plate 22 is welded with a rope head plate 25. Two mounting holes 26 are formed on the outer surface of the rope head plate 25. A rope head 27 is slidably penetrated in the mounting hole 26. One end of the rope head 27 is connected with a steel rope, and the steel rope is arranged on the upper surface of the optical axis 24.

[0032] The guide rail 12 provides accurate guidance for the elevator car. The reinforcing supports 13 are fixedly arranged on the two sides of the mounting plate 11 and are fixedly screwed with the first side plate 21 and the second side plate 22, thereby enhancing the structural strength of the whole device. The rope head plate 25 is welded on one side of the first side plate 21 and the second side plate 22, thereby providing a position for installing and fixing the rope head 27.

[0033] Working principle:

[0034] First, thread the steel cable through one end of the rope head 27. Then, thread the rope head 27 through the mounting hole 26 and fix the rope head on the rope head plate 25. Place the steel cable on the surface of the optical shaft 24 to change the direction of the steel cable. It can be installed at the top of the guide rail 12. The rope head 27 device is installed horizontally to increase the top travel of the car, avoid interference between the rope clamp and the car top wheel, and at the same time reduce the top height. It has strong versatility and is suitable for mass production.

[0035] This step, by installing the rope end 27 horizontally, can effectively increase the top travel of the car. By changing the direction of the steel cable so that it extends along the optical axis 24, the car can move a greater range in the vertical direction.

[0036] Please see Figures 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0037] The maintenance component includes a fixing hole 31 and an oil storage tank 32. The oil storage tank 32 is welded inside the fixing hole 31. The fixing hole 31 is opened on the upper surface of the first side plate 21, and the upper surface of the second side plate 22 is also provided with a corresponding fixing hole 31. The fixing hole 31 and the rotating hole 23 are interconnected. An oil injection valve 33 is fixed at the center of the top surface of the oil storage tank 32, and a rotating ball 34 is rotatably installed at the lower end of the oil storage tank 32, and the rotating ball 34 is in contact with the optical axis 24.

[0038] The main function of the fixing hole 31 is to weld and fix the oil storage tank 32 to the side plate. Lubricating oil is injected into the oil storage tank 32 through the oil injection valve 33. When the optical shaft 24 rotates during the elevator's lifting and lowering process, the rotating bead 34 will be rotated by the friction of the optical shaft 24. The rotating bead 34 then transmits the rotational power of the optical shaft 24 to the oil storage tank 32, so that the lubricating oil inside the oil storage tank 32 can be agitated and flow out as the rotating bead 34 rotates.

[0039] During rotation, the rotating bead 34 generates centrifugal force on the lubricating oil inside the oil storage tank 32, making it easier for the lubricating oil to flow out of the oil storage tank 32 and reach the surface of the optical shaft 24 through the fixed hole 31 and the rotating hole 23, thereby achieving continuous lubrication of the optical shaft 24.

[0040] Working principle:

[0041] During use, the steel cable is placed on the upper surface of the optical shaft 24. When the elevator is raised and lowered, the steel cable moves on the optical shaft 24, causing the optical shaft 24 to rotate in the rotating hole 23. When the optical shaft 24 rotates, it will drive the rotating ball 34 in contact with it to rotate, causing the lubricating oil inside the oil storage tank 32 to flow out and cover the surface of the optical shaft 24.

[0042] This step reduces wear on the optical axis 24 and extends its service life.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
