Description

TECHNICAL FIELD

[0001] The utility model relates to elevator counterweight equipment technical field, concretely relates to a quick -wired elevator counterweight structure. BACKGROUND

[0002] The elevator counterweight, also known as the counterweight, is a device used to balance the weight of the car in the elevator hoisting system. It is located in the elevator shaft, connected to the car through the traction rope, and runs vertically along the counterweight guide rail. The main function of the counterweight device is to reduce the power of the traction motor and the torque on the traction wheel and worm gear, and to balance the weight of the car and part of the load, so that the elevator can run smoothly. However, during the operation of the elevator, the counterweight will move with the car, and during this process, a certain amount of vibration and impact force will be generated. If these vibrations and impact forces are not effectively absorbed and dispersed, they will directly act on the counterweight frame, causing damage to the counterweight frame and unstable operation of the elevator.

[0003] The patent document with Chinese publication number CN213265309U discloses an elevator counterweight structure, which includes a counterweight frame, a counterweight fixed rod, a locking block, a counterweight block, a rotating block and a movable connecting rod. By placing the counterweight block on the connecting support block, the spring at the lower end of the connecting support block is contracted when subjected to force, causing the connecting support block to displace downward. At the same time, the movable connecting rods on the left and right sides of the connecting support block rotate in opposite directions on the rotating block, causing the rotating shafts on the connecting angle of the two movable connecting rods to displace in opposite directions within the sliding grooves. This causes the locking plate at the other end of the movable connecting rod to contact the counterweight block, thereby achieving the fixing effect of the locking plate on the counterweight block, avoiding the situation of noise during the operation of the elevator due to the loosening of the counterweight block.

[0004] The above-mentioned patent document fixes the two sides of the counterweight block through the locking plate, thereby avoiding the loosening of the counterweight block. However, during actual elevator operation, the counterweight block will move with the car, and during this process, a certain amount of vibration and impact force will be generated. These vibrations and impact forces will directly act on the counterweight frame, causing damage to the counterweight frame and unstable operation of the elevator. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0022] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0023] Referring to Figures 1 to 6As shown in the utility model provides a quick -wearing type elevator counterweight structure, including counterweight frame 1, counterweight frame 1 is provided with counterweight block 2, the inner wall of counterweight frame 1 is opened with rectangular slot, and the shock-absorbing assembly 3 for reducing the vibration and impact force generated by counterweight block 2 when the elevator is running is arranged in the rectangular slot, the shock-absorbing assembly 3 includes the moving plate 31 for following the movement of counterweight block 2 and the reset component for driving the movement of moving plate 31, and the fixing assembly 4 for preventing the shaking of counterweight block 2 is further arranged on counterweight frame 1.

[0024] When the elevator is running, counterweight block 2 and the car are connected through the traction rope and the traction wheel, and together constitute the balance part of the elevator traction system. The weight of counterweight block 2 is accurately calculated to match the total weight of the car and the expected load, to ensure that the elevator can keep balance under any load condition. When the elevator is running, counterweight block 2 may vibrate or generate impact force due to the change of traction rope tension, the change of load in the car or other factors in the process of elevator operation. At this time, the moving plate 31 in the shock-absorbing assembly 3 will move following the movement of counterweight block 2, and will absorb and slow down the vibration and impact force through the elastic action of the reset component. The reset component will release energy after being compressed, so that the moving plate 31 returns to the initial position and is ready for the next shock absorption. In addition, through the setting of the fixing assembly 4, the shaking of counterweight block 2 during the operation of the elevator is prevented.

[0025] Referring to Figures 1 to 5 As shown, the reset component includes a damper 32, a fixed box 33, a sleeve 34 and a first spring 35; the damper 32 is provided with two groups, and is arranged on the inner wall of the rectangular slot, and the working end of the damper 32 is connected with the moving plate 31. The fixed box 33 is arranged on the inner wall of the rectangular slot between the two groups of dampers 32; the sleeve 34 is slidingly arranged in the fixed box 33, one end of the sleeve 34 is connected with the moving plate 31; the first spring 35 is arranged in the sleeve 34, and one end of the first spring 35 abuts against the inner wall of the fixed box 33.

[0026] When the elevator is running, the counterweight 2 may be subjected to vibration or impact force due to changes in the tension of the traction rope, changes in the load in the car, or other factors during the operation of the elevator. At this time, the moving plate 31 will move with the movement of the counterweight 2 and drive the sleeve 34 to slide in the fixed box 33. The damper 32 starts to work, slows down the movement of the moving plate 31, and absorbs part of the vibration and impact force. At the same time, the first spring 35 is compressed and stores energy. When the elevator runs smoothly or the vibration and impact force disappears, the resistance of the damper 32 decreases, and the first spring 35 starts to release the stored energy. Under the push of the first spring 35, the sleeve 34 and the moving plate 31 start to move to the initial position. The damper 32 continues to work, but at this time it mainly provides a stable damping force for the reset of the moving plate 31 to prevent it from moving too fast or generating too much impact force. Thus, the effective damping and reset functions of the moving plate 31 are realized, thereby improving the smoothness and safety of the elevator operation.

[0027] Referring to Figure 3 As shown, the two sides of the moving plate 31 are also provided with limiting sliding blocks 36, and the side walls of the rectangular groove are provided with limiting sliding grooves 37 for the movement of the limiting sliding blocks 36.

[0028] When the moving plate 31 moves with the movement of the counterweight 2, the movement of the moving plate 31 drives the limiting sliding blocks 36 to move in the limiting sliding grooves 37, providing a clear boundary for the movement of the moving plate 31. And it ensures that the moving plate 31 can only move within the predetermined range when subjected to vibration or impact force from the counterweight 2, thereby preventing excessive movement or misalignment of the moving plate 31 and improving the stability of the moving plate 31 during movement.

[0029] Referring to Figure 4 As shown, the damping assembly 3 further comprises an extension block 38 and a sliding rod 39; the extension block 38 is arranged at both ends of the moving plate 31; the sliding rod 39 is arranged horizontally in the rectangular groove, the extension block 38 is slidingly arranged on the sliding rod 39, one end of the sliding rod 39 is provided with a limiting block 310, and a second spring 311 is further sleeved on the sliding rod 39, one end of the second spring 311 abuts against the extension block 38, and the other end of the second spring 311 abuts against the inner wall of the rectangular groove.

[0030] When the moving plate 31 moves, it will drive the extension block 38 to slide on the sliding rod 39 and compress the second spring 311. The second spring 311 stores energy when compressed. During this process, the compression of the second spring 311 slows down the movement of the moving plate 31, which helps to improve the damping effect. At the same time, the cooperation of the sliding rod 39 and the extension block 38 ensures the stability of the moving plate 31 during movement, preventing the moving plate 31 from shaking due to vibration or impact force.

[0031] Referring to Figure 6 As shown, the fixed assembly 4 includes a cross plate 41, which is arranged in the counterweight frame 1. A threaded rod 42 is threadedly connected to the cross plate 41. One end of the threaded rod 42 is provided with a knob 43, and the other end of the threaded rod 42 is provided with a pressing plate 44.

[0032] When it is necessary to install the counterweight block 2, the knob 43 is manually rotated. Since the knob 43 is connected to the threaded rod 42, the rotation of the knob 43 drives the threaded rod 42 to rotate. With the rotation of the threaded rod 42, the pressing plate 44 is driven to move towards the counterweight block 2 until it is tightly attached to the upper end of the counterweight block 2, thereby quickly completing the installation of the counterweight block 2. Meanwhile, the surface of the pressing plate 44 is attached with a rubber layer, which increases the friction between the pressing plate 44 and the counterweight block 2, and effectively avoids the shaking of the counterweight block 2 by tightly attaching the pressing plate 44 to the upper end of the counterweight block 2.

[0033] Referring to Figure 6 As shown, the cross plate 41 is provided with a light rod 45 on both sides of the threaded rod 42. One end of the light rod 45 is provided with a limit disc 46, and the other end of the light rod 45 is connected to the pressing plate 44.

[0034] The rotation of the knob 43 drives the threaded rod 42 to rotate, and the threaded rod 42 further drives the pressing plate 44 to move. In this process, the light rod 45 provides a stable guide path for the movement of the pressing plate 44. It ensures that the pressing plate 44 maintains straight-line motion during movement, avoiding deflection or shaking of the pressing plate 44 during movement.

[0035] When the elevator is running, the counterweight block 2 and the car are connected through the traction rope and the traction sheave to form the balance part of the elevator traction system. The weight of the counterweight block 2 is accurately calculated to match the total weight of the car and the expected load, ensuring that the elevator can maintain balance under any load condition. When the elevator is running, the counterweight block 2 may vibrate or be subjected to impact force due to changes in the tension of the traction rope, changes in the load in the car, and other factors. At this time, the moving plate 31 moves with the movement of the counterweight block 2, and the sleeve 34 slides in the fixed box 33. The damper 32 starts to work, slowing down the movement of the moving plate 31 and absorbing part of the vibration and impact force. At the same time, the first spring 35 is compressed and stores energy. When the elevator runs smoothly or the vibration and impact force disappears, the resistance of the damper 32 decreases, and the first spring 35 starts to release the stored energy. Under the push of the first spring 35, the sleeve 34 and the moving plate 31 start to move to the initial position. The damper 32 continues to work, but at this time it mainly provides a stable damping force for the resetting of the moving plate 31 to prevent it from moving too fast or generating too much impact force. Thus, the effective damping and resetting functions of the moving plate 31 are realized, thereby improving the stability and safety of the elevator operation.

It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application.
