Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to a novel cable tensioning and protecting device. Background Art

[0002] As the main component of signal transmission during the operation of the elevator, the traveling cable plays a vital role in the operation of the elevator. The current method of fixing the traveling cable to the wall of the shaft reduces the shaking to a certain extent, but this method is relatively fixed and cannot adapt well to the dynamic changes of the elevator under different speeds and different loads. Even if the upper half of the traveling cable is fixed, the lower half will still move up and down with the elevator car, and the shaking of this part of the cable still exists and cannot be completely avoided. Due to the shaking and space limitations of the traveling cable, even if part of the cable is fixed, it is still possible to collide with other components during the operation of the elevator, produce abnormal noise, or even hang on other components and cause damage. The method of fixing the cable involves structural changes in the shaft wall and the installation of fixings, which increases the difficulty of maintenance and inspection. If the cable is fixed in an improper way, it may affect the operating performance of the elevator, such as increasing the energy consumption of the elevator and reducing the operating efficiency of the elevator.

[0003] In addition, with the development of elevator technology, the utilization rate of shaft space is increasingly required, and the method of fixing cables will further compress the shaft space and affect the design and installation of the elevator. Summary of the invention

[0004] The purpose of the utility model is to provide a novel cable tensioning and protecting device to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of cable tensioning and protecting device, comprising a cable following weight, a roller, a U-groove bearing and a guide column, wherein a roller is installed on the upper end of the cable following weight through a roller frame, and two rows of U-groove bearings are installed on one side of the cable following weight 1, and the U-shaped grooves of the two rows of U-groove bearings are respectively matched with the two side columns of the guide column to keep the cable following weight running vertically in the guide column, and the guide column is installed on the bracket of the hoistway.

[0006] Preferably, the guide column comprises a U-shaped column and a limiting boss, and the limiting bosses are symmetrically arranged at the opposite ends of the U-shaped column, and the opposite surfaces of the two limiting bosses are arc-shaped.

[0007] Preferably, the two rows of U-groove bearings are composed of a plurality of left U-groove bearings and right U-groove bearings, and the left U-groove bearings and the right U-groove bearings are alternately arranged on the cable-following weight.

[0008] Preferably, anti-slip groove plates are symmetrically connected to the cable-following weights at the upper and lower ends of the U-groove bearing, and both sides of the anti-slip groove plates are clamped in the guide columns.

[0009] Technical effects and advantages of the utility model:

[0010] 1. Improved stability and reliability: By installing rollers on the cable-following weight, the cable-following weight can run smoothly vertically in the guide column, thereby ensuring the stable tension of the cable or rope. The design of the U-groove bearing cooperates with the two side columns of the guide column to provide precise guidance and positioning, further enhancing the stability and reliability of the entire device in vertical operation.

[0011] 2. Enhanced safety: The design of the limiting boss, especially the arc structure on its opposite surface, not only helps to position the cable weight in the guide column, but also prevents the cable weight from falling off the guide column under extreme conditions (such as vibration or external force impact), greatly enhancing the safety of the device; the addition of the anti-slip groove plate further strengthens the connection between the cable weight and the guide column, and can effectively prevent the cable weight from falling off the guide column even under high-intensity or high-frequency vibration.

[0012] 3. Good flexibility and maintainability: The U-groove bearing is composed of multiple left U-groove bearings and right U-groove shafts 2, and they are staggered. This design makes the installation and maintenance of the U-groove bearing more flexible and convenient. Since the entire device has a simple structure and modular components, it is easier to replace or repair damaged parts, which improves the maintainability of the device.

[0013] 4. Wide adaptability: This device can adapt to hoistways and cables / ropes of different sizes by simply adjusting the length of the guide column and the number of U-slot bearings. The guide column is installed on the column of the hoistway and can adapt to various hoistway structures and installation environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 5 The utility model shows a specific implementation of a new type of cable tensioning and protecting device, which includes a cable weight 1, a roller 2, an anti-slip groove plate 3, a U-groove bearing 4 and a guide column 5. The roller 2 is installed on the upper end of the cable weight 1 through the roller frame 5, and two rows of U-groove bearings 4 are installed on one side of the cable weight 1. The U-shaped grooves of the two rows of U-groove bearings 4 are respectively matched with the two side columns of the guide column 5 to keep the cable weight 1 running vertically in the guide column 5. The guide column 5 is installed on the bracket of the well, and the anti-slip groove plates 3 are symmetrically connected to the cable weight 1 at the upper and lower ends of the U-groove bearing 4. The two sides of the anti-slip groove plates 3 are clamped in the guide column 5; the connection between the cable weight 1 and the guide column 5 is further strengthened, and the cable weight 1 can be effectively prevented from falling off from the guide column 5 even under high-intensity or high-frequency vibration, thereby ensuring the reliability of system operation;

[0022] Furthermore, the guide column 5 includes a U-shaped column 51 and a limiting shoulder 52. The limiting shoulders 52 are symmetrically arranged at the opposite ends of the U-shaped column 51. The opposite surfaces of the two limiting shoulders 52 are arc-shaped, which effectively prevents the cable-following weight 1 from detaching from the guide column under extreme conditions (such as vibration, external force impact), thereby greatly enhancing the safety of the system.

[0023] Furthermore, the two rows of U-groove bearings 4 are composed of a plurality of left U-groove bearings 41 and right U-groove bearings 42 , and the left U-groove bearings 41 and the right U-groove bearings 42 are alternately arranged on the cable-following weight 1 .

[0024] Roller: The roller is used to hang on the cable. When the elevator moves up and down, one end of the cable moves up and down accordingly. At this time, the roller rotates on the cable as the cable expands and contracts, continuously positioning it and providing tensioning force.

[0025] Heavy hammer: On the one hand, the heavy hammer provides tensioning force for the cable through its own weight. On the other hand, its own anti-slip groove design can prevent the device from falling out of the heavy hammer guide rail due to bearing failure during operation.

[0026] U-groove bearings: Double rows of U-groove bearings are fixed to the weight, and each row of U-groove bearings cooperates with the guide column of the weight guide rail on one side, so that the device can slide freely up and down on the weight guide rail.

[0027] This device changes the physical properties of the accompanying cable through the weight of the cable tensioning and protecting device, so that the natural bending radius of the accompanying cable is reduced from the conventional minimum 125mm to about 50mm (the bending radius depends on the weight of the cable-carrying weight of this device); a special aluminum profile guide column is used as the track of the cable tensioning and protecting device, so that the front, back, left and right positions of the accompanying cable safety tensioning and protecting device are fixed during operation, thereby limiting the operation of the cable tensioning and protecting device in the up and down directions only; after testing, this device can ensure that the accompanying cable can sway within 2mm front, back and left and right.

[0028] The applicant further declares that the present invention illustrates the implementation method and device structure of the present invention through the above embodiments, but the present invention is not limited to the above embodiments, that is, it does not mean that the present invention must rely on the above methods and structures to be implemented. Those skilled in the art should understand that any improvement to the present invention, equivalent replacement of the implementation method selected by the present invention, addition of steps, selection of specific methods, etc., all fall within the scope of protection and disclosure of the present invention.

[0029] The present invention is not limited to the above-mentioned embodiments, and all methods that use structures and methods similar to the present invention to achieve the purpose of the present invention are within the protection scope of the present invention.
