[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] To address the issue of high production costs for elevator compensating ropes, this utility model provides an elevator compensating rope assembly and an elevator.

[0038] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0039] According to embodiments of the present invention, on the one hand, such asFigure 1 As shown in the figure, an elevator compensation rope assembly is provided, comprising: a compensation rope 1 and a guide device 2.

[0040] Specifically, the compensation rope 1 comprises a steel wire rope core 101 and a wrapping layer 102 wrapped outside the steel wire rope core 101, the wrapping layer 102 is made of a material mixed with PVC powder and iron powder or a material mixed with PVC particles and iron powder; the guide device 2 comprises a mounting portion 201 and a magnetic guide portion 202 rotatably mounted on the mounting portion 201, the mounting portion 201 is adapted to the side wall of the elevator shaft 6; the magnetic guide portion 202 is adapted to be in contact with the wrapping layer 102 by magnetic adsorption.

[0041] Compared with a chain rope core, the steel wire rope core 101 is used as the rope core of the compensation rope 1 in the embodiment of the utility model, which can make the structure of the compensation rope 1 simpler, reduce the production process difficulty and preparation cost of the compensation rope 1. Secondly, by wrapping the wrapping layer 102 on the outer surface of the steel wire rope core 101, the weight of the compensation rope 1 can be increased while the bending flexibility of the compensation rope 1 is ensured, so that the compensation rope 1 can better adapt to different operating states of the elevator. Furthermore, by setting the iron powder in the wrapping layer 102, the weight of the compensation rope 1 can be further increased to ensure that it can meet the specified counterweight requirements, and at the same time, the compensation rope 1 can always be attached to the magnetic guide portion 202 under the action of the magnetic adsorption force, avoiding the large swing of the compensation rope 1 during the operation of the elevator.

[0042] It should be noted that the PVC powder in the embodiment is polyvinyl chloride powder, and the PVC particles are polyvinyl chloride particles.

[0043] According to one embodiment of the utility model, as shown in the figure, Figures 1 to 3 As shown in the figure, the magnetic guide portion 202 comprises a rotating rod 2021 and a magnetic guide roller 2022 sleeved on the rotating rod 2021, one end of the rotating rod 2021 extends out of the magnetic guide roller 2022 and is rotatably connected with the mounting portion 201, and the magnetic guide roller 2022 is adapted to be in contact with the wrapping layer 102 by magnetic adsorption. Since the compensation rope 1 moves with the elevator, the relative position between the compensation rope 1 and the magnetic guide portion 202 is not fixed, that is, the friction between the compensation rope 1 and the magnetic guide portion 202 will be generated due to the movement of the compensation rope 1. Compared with sliding friction, the rotating rod 2021 of the embodiment of the utility model is rotatably connected with the mounting portion 201, which can convert the sliding friction between the compensation rope 1 and the magnetic guide roller 2022 into rolling friction. At the same time, since the outer circumferential surface of the magnetic guide roller 2022 is a smooth circular arc surface, the friction between the compensation rope 1 and the magnetic guide roller 2022 can be further reduced, so that the damage to the compensation rope 1 is reduced and the service life of the compensation rope 1 is extended.

[0044] According to one embodiment of the utility model, as shown in Figures 1 to 3 The guiding device 2 further comprises a telescopic piece 203, one of the mounting part 201 and the rotating rod 2021 is connected with the telescopic end of the telescopic piece 203, and the other is connected with the fixed end of the telescopic piece 203. The telescopic piece 203 is arranged between the mounting part 201 and the rotating rod 2021, so that the operator can flexibly adjust the relative position relationship between the magnetic guide roller 2022 and the compensating rope 1, and the adaptability and reliability of the entire elevator compensating rope assembly under different conditions are improved.

[0045] It can be understood that the telescopic piece 203 in the embodiment can be but is not limited to a telescopic rod.

[0046] According to one embodiment of the utility model, as shown in Figure 1 and Figure 2 The magnetic guide part 202 is a pair, and the pair of rotating rods 2021 is fixedly connected with the telescopic end of the telescopic piece 203; the pair of magnetic guide rollers 2022 are arranged in a direction away from each other and form a space suitable for the compensating rope 1 to pass through. The two magnetic guide rollers 2022 can uniformly magnetically attract the compensating rope 1 from both sides, so that the compensating rope 1 can be stably centered and guided when passing through the space, effectively avoiding large left and right deviations of the compensating rope 1 during operation, and improving the stability of the movement of the compensating rope 1.

[0047] It can be understood that the distance between the two magnetic guide rollers 2022 can be adaptively adjusted according to the outer diameter size of the compensating rope 1.

[0048] Preferably, in the embodiment, the outer circumferential surface of the compensating rope 1 is a smooth circular arc surface, so that when the compensating rope 1 moves between the two magnetic guide rollers 2022, the friction between the compensating rope 1 and the magnetic guide roller 2022 can be effectively reduced, so that the movement of the compensating rope 1 is more smooth and stable, and the energy loss caused by friction and the wear degree of the compensating rope 1 itself and the magnetic guide roller 2022 are reduced.

[0049] According to one embodiment of the utility model, as shown in Figure 3As shown, the telescopic members 203 and the rotating rods 2021 are both in pairs, the fixed ends of the telescopic members 203 are arranged at intervals on the mounting portion 201, the rotating rods 2021 are arranged in pairs and connected with the telescopic ends of the telescopic members 203 one by one, and the magnetic guide rollers 2022 are located between the rotating rods 2021 and rotatably connected with the rotating rods 2021. The magnetic guide rollers 2022 are fixed on the mounting portion 201 by means of the pair of magnetic guide rollers 2022 and the pair of rotating rods 2021, can uniformly bear force, improve the rotation stability of the magnetic guide rollers 2022 in the process of contacting with the compensation rope 1, and thus ensure that the compensation rope 1 does not swing greatly on the magnetic guide rollers 2022.

[0050] It should be noted that the guide device 2 in the embodiment is more suitable for being used in cooperation with the compensation rope 1 with a non-circular axial cross-sectional shape. The specific reason is as follows. The axial cross-sectional shape of the magnetic guide roller 2022 is also circular. Although the magnetic guide roller 2022 can also contact with the compensation rope 1 with a circular axial cross-sectional shape under the action of the magnetic attraction force, the contact area between the two is relatively small because of the contact between the circular arc surfaces, and the compensation rope 1 is still prone to swing greatly on the magnetic guide roller 2022. Preferably, the axial cross-sectional shape of the compensation rope 1 is oblate, and the non-circular arc surface of the compensation rope 1 is contacted with the magnetic guide roller 2022.

[0051] It can be understood that even if the guide device 2 in the embodiment is suitable for being used in cooperation with the compensation rope 1 with a non-circular axial cross-sectional shape, in order to ensure that the friction between the two is within a relatively small range, the corners on the outer surface of the compensation rope 1 should be reduced, and the smooth transition of each region of the outer surface of the compensation rope 1 should be ensured.

[0052] According to an embodiment of the utility model, the compensation rope 1 is located in the space defined by the pair of telescopic members 203 and the guide device 2. The utility model embodiment sets the compensation rope 1 in the space defined by the pair of telescopic members 203 and the guide device 2, can limit the maximum swing amplitude of the compensation rope 1, and improves the safety and stability of the operation of the compensation rope 1.

[0053] According to an embodiment of the utility model, as shown in Figure 4 and Figure 5 As shown, the steel wire rope cores 101 are in plurality, adjacent two steel wire rope cores 101 are arranged at intervals, and the wrapping layer 102 is wrapped on the outer side of the plurality of steel wire rope cores 101. The utility model embodiment sets the plurality of steel wire rope cores 101, can improve the durability of the compensation rope 1, and reduce the risk of breaking due to excessive stress.

[0054] Exemplarily, the number of the steel wire rope cores 101 is three, and the three steel wire rope cores 101 are arranged in a triangular shape; or the number of the steel wire rope cores 101 is four, and the four steel wire rope cores 101 are arranged in a square shape.

[0055] According to an embodiment of the present application, Figure 4 and Figure 5 The axial cross-sectional shape of the compensation rope 1 is circular; or the outer circumferential surface of the compensation rope 1 has an arc segment and a plane segment, and the plane segment is in contact with the magnetic guide part 202 through magnetic adsorption. The compensation rope 1 in the embodiment of the present application is arranged in the above two forms, which can effectively reduce the edges and corners on the outer surface of the compensation rope 1 and reduce the friction between the compensation rope 1 and the magnetic guide part 202 during movement.

[0056] According to an embodiment of the present application, the iron powder is 40-80 mesh strong magnetic iron powder. The strong magnetic iron powder with the mesh range has moderate particle size, which can ensure uniform distribution in the wrapping layer 102 after mixing with the PVC powder or PVC particles and fully exert the magnetic properties.

[0057] According to an embodiment of the present application, on the other hand, Figure 1 as shown in the figure, an elevator is also provided, which is suitable for being installed in an elevator shaft 6 and comprises a car 3 and the elevator compensation rope assembly.

[0058] Specifically, the back top of the car 3 is provided with a pair of counterweights 4 and a compensation rope fixing part 5 arranged side by side; one end of the compensation rope 1 is connected with the counterweight 4, and the other end is connected with the compensation rope fixing part 5; the guide device 2 is a pair, which is arranged on the side wall of the elevator shaft 6 below the counterweight 4 along the height direction of the car 3.

[0059] The elevator comprises the elevator compensation rope assembly, and therefore has all the beneficial technical effects of the elevator compensation rope assembly, which will not be described here.
