Description

Technical Field

[0001] This utility model relates to the field of elevator counterweight technology, and in particular to an improved structure for elevator counterweight. Background Technology

[0002] The elevator counterweight frame is an important component of the elevator traction system. Its main function is to support and fix the counterweight blocks, ensuring the stability and safety of the counterweight device during elevator operation. The counterweight frame is usually made of metal materials with sufficient strength and rigidity to withstand the weight of the counterweight blocks and the dynamic loads during operation.

[0003] Publication number CN213326275U discloses an elevator counterweight frame structure. By setting a counterweight block clamping mechanism, the counterweight block can be effectively clamped and fixed to prevent noise from the counterweight block during elevator operation.

[0004] However, the aforementioned patents still have shortcomings. The rotating head needs to be manually turned to fix the weight block to the counterweight, which not only leads to low work efficiency but also increases the labor intensity. Therefore, we propose an improved elevator counterweight frame structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an improved structure for elevator counterweights to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An improved counterweight structure for an elevator includes a lower beam, on the upper surface of which symmetrical support beams are fixedly installed. An upper beam is fixedly installed on the upper surfaces of the two support beams. Grooves are formed on the sides of the two support beams that are close to each other. Several weight blocks are arranged inside the two sets of grooves. An installation cavity is formed inside the upper beam. A rotary motor is fixedly installed inside the installation cavity. A bearing is embedded in the bottom surface of the upper beam. A threaded rod is fixedly connected to the inner ring of the bearing. The output end of the rotary motor is connected to the top end of the threaded rod through the bearing. A pressure block is threadedly connected to the outer surface of the threaded rod.

[0008] In a further embodiment, the pressure block has an internal movable cavity, the bottom end of the threaded rod passes through the pressure block and extends into the interior of the movable cavity, and the bottom end of the threaded rod is fixedly connected to a limiting plate.

[0009] In a further embodiment, a protective pad is fixedly connected to the bottom surface of the pressure block, and the bottom surface of the protective pad is in contact with the upper surface of one of the weight blocks.

[0010] In a further embodiment, a symmetrical positioning block is fixedly connected to the outer surface of the pressure block, and a sliding rod is fixedly connected to the upper surface of each of the two positioning blocks. The top ends of the two sliding rods penetrate the upper beam and extend into the interior of the mounting cavity.

[0011] In a further embodiment, the bottom surface of the lower beam is fixedly connected with symmetrical buffer pads, both of which are made of rubber.

[0012] In a further embodiment, symmetrical reinforcing plates are fixedly connected to the outer surfaces of the two support beams, and symmetrical heat dissipation holes are provided on the outer surface of the upper beam.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device uses a rotary motor to drive a threaded rod to rotate, which in turn causes a pressure block to automatically press down and fix the weight, thus ensuring that the weight remains stable during elevator operation. This reduces noise and safety hazards caused by loosening. The device eliminates the need for manual operation, significantly reducing the labor intensity of operators and making the fixing process more convenient, efficient, and stable.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4In this utility model, an improved structure for an elevator counterweight frame includes a lower beam 1. Symmetrical support beams 2 are fixedly installed on the upper surface of the lower beam 1. An upper beam 3 is fixedly installed on the upper surfaces of the two support beams 2. Grooves 6 are provided on the sides of the two support beams 2 that are close to each other. Several weight blocks 5 are provided inside the two sets of grooves 6. An installation cavity 7 is provided inside the upper beam 3. A rotary motor 8 is fixedly installed inside the installation cavity 7. A bearing 9 is embedded in the bottom surface of the upper beam 3. A threaded rod 10 is fixedly connected to the inner ring of the bearing 9. The output end of the rotary motor 8 is connected to the top end of the threaded rod 10 through the bearing 9. A pressure block 12 is threadedly connected to the outer surface of the threaded rod 10. The lower beam 1, support beams 2, and upper beam 3 are fixedly installed using screws, enabling the assembly of a counterweight frame. This facilitates subsequent installation and disassembly of the counterweight frame. The cooperation of the rotary motor 8, bearing 9, threaded rod 10, and pressure block 12 enables the fastening of the weight blocks 5, improving the automation of the device. The grooves 6 serve to limit the movement of the weight blocks 5.

[0024] The pressure block 12 has an internal movable cavity 13. The bottom end of the threaded rod 10 passes through the pressure block 12 and extends into the movable cavity 13. The bottom end of the threaded rod 10 is fixedly connected to a limiting plate 11. Through the cooperation of the limiting plate 11 and the movable cavity 13, the threaded rod 10 can be prevented from being excessively screwed out, causing the pressure block 12 to fall off.

[0025] A protective pad 14 is fixedly connected to the bottom surface of the pressure block 12. The bottom surface of the protective pad 14 is in contact with the upper surface of one of the weight blocks 5, which can buffer the rigid contact between the pressure block 12 and the weight block 5 and prevent the surface of the weight block 5 from being worn.

[0026] The outer surface of the pressure block 12 is fixedly connected with symmetrical positioning blocks 15. The upper surfaces of the two positioning blocks 15 are fixedly connected with slide rods 16. The top ends of the two slide rods 16 pass through the upper beam 3 and extend into the interior of the mounting cavity 7. Through the cooperation of the positioning blocks 15 and the slide rods 16, the pressure block 12 can always maintain vertical movement during the lifting process, and avoid the pressure block 12 from shifting due to the rotation of the threaded rod 10.

[0027] The bottom surface of the lower beam 1 is fixedly connected with symmetrical buffer pads 17. Both buffer pads 17 are made of rubber. By providing buffer pads 17, the impact vibration of the counterweight frame during operation can be absorbed.

[0028] Two supporting beams 2 are fixedly connected to symmetrical reinforcing plates 4 on their outer surfaces. The outer surface of the upper beam 3 is provided with symmetrical heat dissipation holes 18. By providing reinforcing plates 4, the strength of the counterweight frame structure can be enhanced, and the counterweight frame can be prevented from deforming under long-term load. By providing heat dissipation holes 18, the air flow in the mounting cavity 7 can be facilitated, and the rotating motor 8 can be prevented from overheating.

[0029] The working principle of this utility model is as follows:

[0030] During use, firstly, the weights 5 are placed into the grooves 6 inside the support beam 2. Then, the rotary motor 8 is started. The rotary motor 8 drives the threaded rod 10 to rotate through the bearing 9. When the threaded rod 10 rotates, the pressure block 12, which is threadedly connected to the threaded rod 10, moves downward due to the limiting effect of the slide rod 16. The protective pad 14 on the bottom surface of the pressure block 12 gradually contacts and presses the uppermost weight 5 until the weight 5 is firmly fixed, and the rotary motor 8 stops running.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
