Description

Technical Field

[0001] The utility model relates to the technical field of elevator accessories, in particular to an elevator compensation chain with a self-balancing structure. Background Technique

[0002] In order to balance the gravity of the counterweight and the car, a compensation chain is connected between the bottom of the car and the bottom of the counterweight to form a closed loop, thereby reducing the influence of the steel wire rope on the elevator system. The compensation chain itself also has a unit mass. As the building height increases, the weight of the compensation chain needs to be changed. Conventionally, the compensation chain is installed on the car or the counterweight block.

[0003] In the existing technology, the length of the elevator steel wire rope is proportional to the weight of the compensation chain. Due to the long compensation chain, there is inevitably a shaking phenomenon inside the elevator shaft, which affects the up and down operation of the elevator and even causes certain danger.

[0004] The existing patent (publication number: CN217024925U) discloses an elevator compensation chain self-balancing device. When measurement is required, the elevator compensation chain self-balancing device of the utility model can adjust the horizontal position of the compensation chain at the bottom of the elevator car or the counterweight by compressing the left spring or the right spring through installing a balance component at the bottom of the elevator car or the counterweight, so as to automatically adjust the mass on one side of the car due to the change of the compensation chain length during the operation of the elevator.

[0005] In view of the above problems, although the solution given by the existing patent can cooperate with components such as the left spring to compensate for the weight and automatically adjust the balance, in the specific use process, for structures such as the fixing ring carrying the compensation chain, only the cooperation of the sliding rod and the sleeve rod is relied on for support. In addition, since self-balancing needs to be achieved by moving, the compensation chain is in a movable state. At the same time, the compensation chain body is heavy, resulting in a large burden after long-term use, and the sliding rod and the sleeve rod are bent or deformed, affecting the self-balancing effect. Summary of the Invention

[0006] The purpose of the utility model is to provide an elevator compensation chain with a self-balancing structure, which can adjust the position and angle according to the self-balancing adjustment of the compensation chain, and can improve the bearing strength to avoid the situation that the components are bent or deformed due to the over-large weight of the compensation chain, so as to solve the problems put forward in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: An elevator compensation chain with a self-balancing structure, including an installation base body, and a connection mechanism is arranged below the installation base body;

[0008] The connection mechanism includes a fixed shell. Two fixed shells are fixed on both sides of the bottom end of the installation base body. A chute is provided inside the fixed shell. A connection frame is slidably connected inside the chute. A micro roller is rotatably connected to the outside of the axial end of the connection frame penetrating into the chute. A limiting plate is fixed at the bottom end of the connection frame. A contact roller is slidably connected inside the limiting plate. A first universal ball is fixed at the bottom end of the contact roller. A connecting plate is connected below the first universal ball. A connection block is fixed at the bottom end of the connecting plate.

[0009] Preferably, a sliding structure is formed between the limiting plate and the contact roller, and the limiting plate is detachably connected to the connection frame by bolts.

[0010] Preferably, support rods are fixed on the two axially opposite surfaces at the bottom end of the connection block, and limiting holes are provided inside the inner walls of the support rods.

[0011] Preferably, fixing plates are fixed at both ends of the fixed shell at the bottom end of the installation base body, and a balancing mechanism is provided on the outer wall of the fixing plates.

[0012] Preferably, the balancing mechanism includes a placement frame. The two placement frames are respectively fixed on the opposite surfaces of the two fixing plates. A fixed rod is fixed on the outside of the placement frame. A sliding frame is slidably connected to the outside of the fixed rod. A rotating frame is rotatably connected to the axial end of the sliding frame.

[0013] Preferably, the balancing mechanism further includes a second universal ball. The second universal ball is fixed at the end of the rotating frame away from the sliding frame. A bearing rod is connected to the outer wall of the second universal ball. A spring is sleeved on the outside of the bearing rod. One end of the bearing rod away from the second universal ball penetrates into a sleeve.

[0014] Preferably, a sliding structure is formed between the bearing rod and the sleeve, and an elastic structure is formed between the sleeve and the second universal ball through the spring.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

In cooperation with the limiting plate and the contact roller for transverse movement, and through the first universal ball to drive the connection block by the connecting plate, the position and angle can be adjusted according to the self-balancing adjustment of the compensating chain. At the same time, the bearing capacity can be improved, avoiding the situation that the excessive weight of the compensating chain causes bending or deformation of the components.

[0017] 2. Through the placement frame, fixed rod, sliding frame, rotating frame and the second universal ball, the position of the compensating chain in the transverse direction can be adjusted. At the same time, when adjusting the longitudinal position in cooperation with the bearing rod, spring and sleeve, it has a certain buffering force and can be automatically adjusted, achieving the effect of automatic balance.

On the two axially opposite surfaces at the bottom end of the connection block 209, support rods 3 are fixed, and limiting holes 4 are opened on the inner walls of the support rods 3.

[0028] By adopting the above technical solution, the connection block 209 limits the compensation chain through the limiting holes 4 opened in the support rods 3. Through the chute 202 opened in the fixed shell 201, the connection frame 203 slides stably through the micro roller 204, and the two limiting plates 205 cooperate to limit the contact roller 206 and keep it sliding stably. The connecting plate 208 can drive the connection block 209 to slide horizontally or vertically, and cooperate with the first universal ball 207 to adjust the angle. Thus, when the compensation chain performs self-balancing displacement or angle adjustment, the connection block 209 can be kept sliding stably, and the bearing capacity can be improved to avoid deformation of other components caused by excessive weight. The fixed shell 201 of the connection mechanism 2 is installed at the bottom end of the installation base 1 by bolts, improving the overall bearing strength.

[0029] Specifically, as Figure 1 、 Figure 2 and Figure 4 shown, fixing plates 5 are fixed at both ends of the fixed shell 201 at the bottom end of the installation base 1, a balance mechanism 6 is arranged on the outer wall of the fixing plates 5. The balance mechanism 6 includes a placement frame 601, two placement frames 601 are respectively fixed on the opposite surfaces of the two fixing plates 5, a fixed rod 602 is slidably connected to the outside of the placement frame 601, a sliding frame 603 is fixed to the outside of the fixed rod 602, a rotating frame 604 is rotatably connected to the axial end of the sliding frame 603. The balance mechanism 6 further includes a second universal ball 605, the second universal ball 605 is fixed at one end of the rotating frame 604 away from the sliding frame 603, a bearing rod 606 is connected to the outer wall of the second universal ball 605, a spring 607 is sleeved on the outside of the bearing rod 606, one end of the bearing rod 606 away from the second universal ball 605 penetrates into a sleeve 608, a sliding structure is formed between the bearing rod 606 and the sleeve 608, and an elastic structure is formed between the sleeve 608 and the second universal ball 605 through the spring 607.

The spring 607 is compressed through the sleeve 608 and stably slides longitudinally along the bearing rod 606, which can play a buffering role during movement. The stability and bearing capacity are improved by the two placement frames 601, and the overall bearing rod 606 is cooperated to avoid deformation.

[0031] Working principle: The installation base 1 is at the bottom of the elevator car or the counterweight. The connecting block 209 places the compensation chain through the limiting hole 4 of the support rod 3. The connecting plate 208 at the top of the connecting block 209 is movably connected through the first universal ball 207 and the abutting roller 206. The abutting roller 206 penetrates into the limiting plate 205 and cooperates with the micro roller 204 of the connecting frame 203 to slide in the fixed shell 201 along the sliding groove 202, so as to bear and share the gravity of the compensation chain. The placement frame 601 fixed by the fixed plate 5 can support the cooperation of the fixed rod 602 and the sliding frame 603 to move, and can be adjusted at different angles in cooperation with the rotating frame 604 and the second universal ball 605. Cooperating with the sleeve 608 outside the bearing rod 606, it can drive the connecting block 209 to compress the spring 607, and reset after following the self-balancing adjustment of the compensation chain and can obtain buffering.
