Description

Technical Field

[0001] This utility model relates to the field of counterweight support technology, and in particular to a counterweight support. Background Technology

[0002] A counterweight bracket is a device used to limit the counterweight. When using a counterweight bracket, the counterweight is placed inside the bracket, and then the bracket is placed at the bottom of the elevator car. This can effectively counterweight the elevator car and facilitate the normal operation of the elevator.

[0003] The inventors discovered in their daily work that the counterweight support still has at least the following problems: When using the counterweight support, the counterweight is placed inside the support, and then the support is placed at the bottom of the elevator car. This can effectively counterweight the elevator car and facilitate the normal operation of the elevator. However, in actual use, because the counterweight is placed inside the support, when replacing the counterweight, the entire support frame needs to be disassembled, which is quite troublesome. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a counterweight support.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a counterweight support, comprising a support body, wherein support rods are uniformly arranged inside the support body, and the counterweight body is slidably sleeved on the surface of the support rods. A moving device is provided at the bottom of the inner wall of the support body, the moving device comprising a moving plate, the moving plate being disposed at the bottom of the inner wall of the support body, and the top of the moving plate being fixedly connected to the bottom of the support rods.

[0006] The effect achieved by the above components is that when using the moving device, the control moving plate slides at the bottom of the inner wall of the support body, which makes it easier to move the counterweight body out of the support body and thus facilitates the replacement of the counterweight body.

[0007] Preferably, a sliding groove is provided at the bottom of the inner wall of the support body, a rectangular strip is fixedly connected to the inner wall of the sliding groove, a sliding plate is slidably fitted on the surface of the rectangular strip, and the top of the sliding plate and the bottom of the sliding plate are fixedly connected.

[0008] The effect achieved by the above components is that when the movable plate slides at the bottom of the support body, the movable plate is driven to slide on the surface of the rectangular bar, which can prevent the movable plate from sliding completely out of the interior of the support body.

[0009] Preferably, a limiting frame is slidably fitted on the bottom surface of the support body, and limiting grooves are opened on both sides of the support body, with one end of the limiting frame slidably connected to the inner wall of the limiting groove.

[0010] The effect achieved by the above components is that the limit frame can be manually controlled to slide on the inner wall of the limit groove, thereby fitting the limit frame onto the surface of the support body and the counterweight body, thus restricting the moving plate to the bottom of the inner wall of the support body.

[0011] Preferably, a storage groove is provided on one side of the inner wall of the limiting groove, a locking block is slidably connected to the inner wall of the storage groove, a first damping rod is fixedly connected to one side of the inner wall of the storage groove, the end of the first damping rod away from the storage groove is fixedly connected to one side of the locking block, a first spring is sleeved on the surface of the first damping rod, one end of the first spring is fixedly connected to one side of the inner wall of the storage groove, the end of the first spring near the locking block is fixedly connected to one side of the locking block, a fixing groove is provided on one side of the locking block, a rubber block is provided on the inner wall of the fixing groove, and one side of the rubber block is fixedly connected to one side of the inner wall of the limiting groove.

[0012] The effect achieved by the above components is as follows: the first spring presses the locking block away from the storage groove, thereby pressing the rubber block into the interior of the fixing groove. This makes it easier to restrict the locking block outside the storage groove, and thus makes it easier to restrict the limiting frame to the surface of the counterweight body and the bracket body through the locking block.

[0013] Preferably, the surface of the support rod is provided with a fixing device, the fixing device including a fixing frame, two fixing frames are sleeved on the top surface of the support rod, a second damping rod is fixedly connected between the two fixing frames, a second spring is sleeved on the surface of the second damping rod, and the two ends of the second spring near the fixing frame are fixedly connected to the side of the fixing frame near the second damping rod.

[0014] The effect achieved by the above components is that when the fixing device is used, the second spring pulls the surface of the top of the support rod, which makes it easier to restrict the counterweight body inside the support body, and thus restrict the fixing frame to the top of the counterweight body.

[0015] Preferably, the fixed frame is fixedly connected to a rubber strip on the side near the support rod, the rubber strip is sleeved on the surface of the support rod, and the surface of the support rod is uniformly fixedly connected with protrusions.

[0016] The effect achieved by the above components is that after the fixing frame is fitted onto the surface of the support rod, the rubber strip is pressed against the raised surface, which causes the rubber to be deformed by compression, thereby making it easier to restrict the fixing frame to the surface of the support rod.

[0017] Preferably, a rectangular groove is provided at the top of each of the two fixed frames, a rectangular plate is slidably connected to the inner wall of the rectangular groove, a third damping rod is fixedly connected to the top of the inner wall of the rectangular groove, the top of the third damping rod is fixedly connected to the bottom of the rectangular plate, a third spring is sleeved on the surface of the third damping rod, one end of the third spring is fixedly connected to the bottom of the inner wall of the rectangular groove, and the third spring is fixedly connected to the bottom of the rectangular plate near the bottom of the rectangular plate. A fixing rod is fixedly connected to the bottom of the inner wall of the other rectangular groove, and the fixing rod is slidably inserted through the bottom of the rectangular plate.

[0018] The effect achieved by the above components is that the rectangular plate is pulled towards the rectangular groove by the third spring, thereby allowing the fixing rod to pass through the rectangular plate, which makes it easier to restrict the two fixing frames to the surface of the support rod.

[0019] Preferably, a rubber cone block is fixedly connected to the top of the fixing rod, and the rubber cone block is disposed on the top of the rectangular plate.

[0020] The effect achieved by the above components is that after the fixing rod passes through the rectangular plate, the rubber cone block is set on the top of the rectangular plate, which makes it easier to restrict the rectangular plate to the surface of the fixing rod.

[0021] In this utility model, by setting a moving device, when using the moving device, the moving plate is controlled to slide at the bottom of the inner wall of the support body, which makes it easy to move the counterweight body out of the interior of the support body, thus making it easy to replace the counterweight body.

Detailed Implementation

[0024] Example 1, such as Figure 1-4 As shown, a counterweight bracket has support rods 2 evenly arranged inside the bracket body 1, and a counterweight body 3 is slidably sleeved on the surface of the support rods 2. A moving device 4 is provided at the bottom of the inner wall of the bracket body 1. When using the counterweight bracket, the counterweight is placed inside the bracket, and then the bracket is placed at the bottom of the elevator car. This can effectively counterweight the elevator car and facilitate the normal operation of the elevator.

[0025] Reference Figure 2 and Figure 3The moving device 4 includes a moving plate 402, which is disposed at the bottom of the inner wall of the support body 1. The top of the moving plate 402 is fixedly connected to the bottom of the support rod 2. When using the moving device 4, the moving plate 402 is controlled to slide at the bottom of the inner wall of the support body 1, which facilitates the removal of the counterweight body 3 from the interior of the support body 1 and facilitates the replacement of the counterweight body 3. A groove 401 is provided at the bottom of the inner wall of the support body 1. A rectangular strip 403 is fixedly connected to the inner wall of the groove 401. A sliding plate 404 is slidably fitted on the surface of the rectangular strip 403. The top of the sliding plate 404 and the bottom of the support rod 2 are fixedly connected to the support rod 2. The bottom of the movable plate 402 is fixedly connected. When the movable plate 402 slides at the bottom of the support body 1, the sliding plate 404 is driven to slide on the surface of the rectangular bar 403. This prevents the movable plate 402 from sliding completely out of the support body 1. A limiting frame 405 is slidably fitted on the bottom surface of the support body 1. Limiting grooves 406 are opened on both sides of the support body 1. One end of the limiting frame 405 is slidably connected to the inner wall of the limiting groove 406. The limiting frame 405 is manually controlled to slide on the inner wall of the limiting groove 406, thereby fitting the limiting frame 405 onto the support body 1 and the counterweight body 3. The surface of the body allows the movable plate 402 to be confined to the bottom of the inner wall of the support body 1. A storage groove 407 is provided on one side of the inner wall of the limiting groove 406. A locking block 408 is slidably connected to the inner wall of the storage groove 407. A first damping rod 409 is fixedly connected to one side of the inner wall of the storage groove 407. The end of the first damping rod 409 away from the storage groove 407 is fixedly connected to one side of the locking block 408. A first spring 410 is sleeved on the surface of the first damping rod 409. One end of the first spring 410 is fixedly connected to one side of the inner wall of the storage groove 407. The first spring 410 is close to the locking block 408. One end of the device is fixedly connected to one side of the locking block 408. A fixing groove 411 is provided on one side of the locking block 408. A rubber block 412 is provided on the inner wall of the fixing groove 411. One side of the rubber block 412 is fixedly connected to one side of the inner wall of the limiting groove 406. The locking block 408 is pressed away from the storage groove 407 by the first spring 410, thereby pressing the rubber block 412 into the inside of the fixing groove 411. This makes it easy to restrict the locking block 408 outside the storage groove 407, and thus makes it easy to restrict the limiting frame 405 on the surface of the counterweight body 3 and the bracket body 1 by the locking block 408.

[0026] Reference Figure 4A fixing device 5 is provided on the surface of the support rod 2. The fixing device 5 includes a fixing frame 502. Two fixing frames 502 are sleeved on the top surface of the support rod 2. A second damping rod 503 is fixedly connected between the two fixing frames 502. A second spring 504 is sleeved on the surface of the second damping rod 503. The two ends of the second spring 504 near the fixing frame 502 are fixedly connected to the side of the fixing frame 502 near the second damping rod 503. When using the fixing device 5, the top surface of the support rod 2 is pulled relative to each other by the second spring 504, which facilitates the restriction of the counterweight body 3. Inside the main body 1 of the support frame, the fixing frame 502 is further constrained at the top of the counterweight body 3. Rubber strips 505 are fixedly connected to the side of the fixing frame 502 closest to the support rod 2. The rubber strips 505 are fitted onto the surface of the support rod 2. Protrusions 501 are evenly fixedly connected to the surface of the support rod 2. When the fixing frame 502 is fitted onto the surface of the support rod 2, the rubber strips 505 are pressed against the surface of the protrusions 501, causing the rubber to deform and thus facilitating the confinement of the fixing frame 502 to the surface of the support rod 2. Rectangular grooves 506 are provided at the top of both fixing frames 502. A rectangular plate 509 is slidably connected to the inner wall of a rectangular groove 506. A third damping rod 507 is fixedly connected to the top of the inner wall of the rectangular groove 506. The top of the third damping rod 507 is fixedly connected to the bottom of the rectangular plate 509. A third spring 508 is sleeved on the surface of the third damping rod 507. One end of the third spring 508 is fixedly connected to the bottom of the inner wall of the rectangular groove 506. The third spring 508 is also fixedly connected to the bottom of the rectangular plate 509 near the bottom of the rectangular plate 509. A fixing rod 510 is fixedly connected to the bottom of the inner wall of another rectangular groove 506. The fixing rod 510 is slidably inserted through the groove. At the bottom of the rectangular plate 509, the third spring 508 pulls the rectangular plate 509 towards the rectangular groove 506, thereby causing the fixing rod 510 to pass through the rectangular plate 509. This makes it easier to restrict the two fixing frames 502 to the surface of the support rod 2. A rubber cone block 511 is fixedly connected to the top of the fixing rod 510. The rubber cone block 511 is set on the top of the rectangular plate 509. After the fixing rod 510 passes through the rectangular plate 509, the rubber cone block 511 is set on the top of the rectangular plate 509, which makes it easier to restrict the rectangular plate 509 to the surface of the fixing rod 510.

[0027] Working principle: When using the counterweight bracket, the counterweight is placed inside the bracket, which is then placed at the bottom of the elevator car. This effectively counterweights the elevator car, facilitating normal elevator operation. When using the moving device 4, the moving plate 402 slides at the bottom of the inner wall of the bracket body 1, allowing the counterweight body 3 to be moved out of the bracket body 1 for easy replacement. When the moving plate 402 slides at the bottom of the bracket body 1, the sliding plate 404 is driven to slide on the surface of the rectangular strip 403, preventing the moving plate 402 from completely sliding out of the bracket body 1. The limiting frame 405 is manually controlled to slide on the inner wall of the limiting groove 406, thus fitting the limiting frame 405 onto the surfaces of the bracket body 1 and the counterweight body 3. The first spring 410 presses the locking block 408 away from the storage groove 407, thus pressing the rubber block 412 into the fixing groove 411, thus restricting the locking block 408 outside the storage groove 407 for easy passage. The locking block 408 restricts the limiting frame 405 to the surface of the counterweight body 3 and the support body 1, thus restricting the moving plate 402 to the bottom of the inner wall of the support body 1. When using the fixing device 5, the second spring 504 pulls the surface of the top of the support rod 2 relative to each other. After the fixing frame 502 is fitted onto the surface of the support rod 2, the third spring 508 pulls the rectangular plate 509 towards the rectangular groove 506, thereby causing the fixing rod 510 to pass through the rectangular plate 509. After step 509, a rubber cone block 511 is placed on top of the rectangular plate 509, which facilitates the restriction of the rectangular plate 509 to the surface of the fixing rod 510, and the restriction of the two fixing frames 502 to the surface of the support rod 2. The rubber strip 505 is pressed against the surface of the protrusion 501, which causes the rubber to be compressed and deformed, thereby facilitating the restriction of the fixing frame 502 to the surface of the support rod 2, and facilitating the restriction of the counterweight body 3 inside the bracket body 1, thereby restricting the fixing frame 502 to the top of the counterweight body 3.

[0028] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
