Description

Technical Field

[0001] The utility model relates to the technical field related to elevator accessories, and in particular to an elevator counterweight compensation chain installation structure. Background Art

[0002] The compensating chain is a component used to compensate for the weight imbalance between the car and the counterweight caused by the traction rope during elevator operation. Its main function is to balance the changes caused by changes in the wire rope and accompanying cable during elevator operation.

[0003] After extensive searching, I discovered Chinese patent publication number CN206827885U, which discloses a counterweight compensation chain frame. This patent relates to the field of elevator technology. The patent provides a compensation wheel guide rail bracket, including a counterweight mechanism and a compensation chain connected to the bottom of the counterweight mechanism. The patent is characterized in that a counterweight compensation chain frame body is mounted on the bottom of the counterweight mechanism and connected to the compensation chain. The counterweight compensation chain frame body includes a counterweight block seat, a compensation chain fixing seat, and a compensation chain buffer structure disposed between the counterweight block seat and the compensation chain fixing seat. This patent converts the potential energy generated by the compensation chain into elastic potential energy of the compensation chain buffer structure, preventing it from being converted into kinetic energy of the compensation chain itself.

[0004] In summary, with the demand for elevators with large lifting heights, the length of elevator wire ropes is getting longer and longer, and the weight of the compensation chain will also increase accordingly. The existing compensation chain installation structure cannot effectively eliminate problems such as wear and deformation that occur during normal operation.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create an elevator reusable compensation chain installation structure to make it more valuable for industrial use. Utility Model Content

[0010] The compensation chain mounting structure includes an adapter block. A first mounting groove is provided at the bottom of the counterweight mechanism directly above the adapter block. The top of the adapter block is clamped in the first mounting groove through a limit clamp block. A bearing is installed in the first mounting groove outside the adapter block.

[0011] A second mounting groove is provided at the bottom of the adapter block, a connecting rod is installed in the second mounting groove, and the top of the compensation chain is connected to the upper connecting rod through a pull ring.

[0012] As a further improvement of the present invention, an elastic pad is installed in the first installation groove above the adapter block, and the arc-shaped convex surface at the bottom of the elastic pad is in contact with the top of the adapter block below.

[0013] As a further improvement of the present invention, the elastic pad is a rubber block.

[0014] As a further improvement of the present invention, springs are installed on the connecting rods on both sides of the pull ring.

[0015] As a further improvement of the present invention, at least one compensating chain guide structure is provided below the compensating chain along the direction of the compensating chain.

[0016] As a further improvement of the present invention, the compensation chain guide structure includes a guide shell, with guide wheels provided on both sides of the guide shell. The guide wheels are installed in the guide shell along the front and rear directions through the guide frame, and the compensation chain is positioned between the two guide wheels.

[0031] Example

[0032] like Figures 1 to 3 As shown,

[0033] A compensation chain installation structure for an elevator counterweight comprises a counterweight mechanism 1 and a plurality of compensation chains 2 evenly distributed at the bottom of the counterweight mechanism 1. The top of the compensation chain 2 is installed at the bottom of the counterweight mechanism 1 through a compensation chain installation structure 3.

[0034] 1. Compensation chain installation structure 3:

[0035] The compensation chain mounting structure 3 includes an adapter block 6. A first mounting slot 5 is provided at the bottom of the counterweight mechanism 1, directly above the adapter block 6. The top of the adapter block 6 is engaged within the first mounting slot 5 via a limit block 7. A bearing 8 is installed within the first mounting slot 5 outside the adapter block 6. A second mounting slot 10 is provided at the bottom of the adapter block 6. A connecting rod 11 is installed within the second mounting slot 10. The top of the compensation chain 2 is connected to the connecting rod 11 above via a pull ring 12.

[0036] The coordination between the adapter block 6 and the bearing 8 allows the adapter block 6 to rotate within the first mounting slot 5, thereby causing the compensation chain 2 to rotate accordingly. The compensation chain 2 is connected to the upper connecting rod 11 via a pull ring 12, allowing the compensation chain 2 to swing through a certain angle.

[0037] 1. An elastic pad 9 is installed in the first mounting groove 5 above the adapter block 6. The elastic pad 9 is a rubber block. The arc-shaped convex surface at the bottom of the elastic pad 9 contacts the top of the adapter block 6 below, so that the rotation of the adapter block 6 can be blocked to a certain extent to prevent excessive rotation.

[0038] 2. Springs 13 are installed on the connecting rods 11 on both sides of the pull ring 12. The springs 13 on the left and right sides can make the swing process of the pull ring 12 more stable.

[0039] 2. Compensation chain guide structure 4:

[0040] At least one compensating chain guide structure 4 is arranged below the compensating chain 2 along the course of the compensating chain 2 .

[0041] The compensating chain guide structure 4 includes a guide housing 14, with guide wheels 15 installed on both the left and right sides of the guide housing 14. The guide wheels 15 are installed in the guide housing 14 along the front-to-back direction via a guide frame 16. The compensating chain 2 is positioned between the two guide wheels 15. The two guide wheels 15 guide and limit the middle compensating chain 2 to prevent it from swinging too much.

[0042] 1. The outer surface of the guide wheel 15 is an arc-shaped convex structure to increase the contact with the inner compensation chain 2.

[0043] 2. The outer surface of the guide wheel 15 is covered with a rubber sleeve to prevent the guide wheel 15 from scratching the outer surface of the compensation chain 2.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implying the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0045] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
