Description

Technical Field

[0001] The utility model relates to an elevator counterweight structure, in particular to an elevator counterweight structure, belonging to the technical field of elevator counterweight structures. Background Technique

[0002] An elevator refers to a mechanical and electrical device that is power-driven and uses a rigid guide rail to run a box body or a step (tread) running along a fixed line to lift or horizontally transport people and goods, including passenger (cargo) elevators, escalators, and moving walks. The elevator counterweight is an important part of the elevator system, and it plays a crucial role in ensuring the smooth operation and safety performance of the elevator.

[0003] The elevator counterweight structures of the prior art have the following disadvantages: 1. There are multiple counterweight blocks installed in the elevator counterweight structure. After a certain counterweight block is damaged, it is necessary to take out the counterweight blocks above this counterweight block in the counterweight structure one by one and then replace it, which is inconvenient for replacement; 2. During the use of the elevator counterweight structure, it falls and contacts the ground and other places, and the vibration damping and buffering performance is poor. After many times, the inner counterweight blocks are easily damaged. Therefore, improvements are made to the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an elevator counterweight structure to solve the above problems. The motor a and the hydraulic cylinder a cooperate to drive the counterweight block above the counterweight block to be replaced to move upward, which can facilitate the replacement of the counterweight block; the components in the vibration damping box cooperate to achieve a better vibration damping and buffering effect.

[0005] The utility model realizes the above purpose through the following technical solutions. An elevator counterweight structure includes a counterweight frame. The counterweight frame is fixedly connected with a partition board. The partition board is provided with a hydraulic cylinder a. The hydraulic cylinder a is provided with a moving frame. The moving frame is rotatably connected with a screw rod. The screw rod is threadedly connected with an insertion plate. The insertion plate is located outside the counterweight block. The counterweight frame is provided with a vibration damping box. An electric push rod is installed in the vibration damping box. The electric push rod is provided with an insertion rod. The insertion rod is inserted into a baffle. The insertion rod is threadedly connected with a nut. The baffle is rotatably connected with a side plate. The counterweight frame is provided with a damping rod. The damping rod is surrounded by a spring b. The spring b is provided with a vibration damping plate.

[0006] Preferably, a top plate is installed at the top end of the counterweight frame, and side plates are installed on both sides of the top plate.

[0007] Preferably, a motor b is installed below the top plate, and the output end of the motor b is fixedly connected with a rotating shaft.

[0008] Preferably, a baffle is installed on the rotating shaft. The baffle is located outside the counterweight block. Convex blocks are installed at the upper end of the counterweight block and the bottom of the counterweight frame.

[0009] Preferably, a hydraulic cylinder b is installed on the partition board, a pressing plate is installed on the hydraulic cylinder b, and a spring a is installed on the pressing plate.

[0010] Preferably, a motor a is installed on the support frame, the output end of the motor a is fixedly connected to a screw rod, the screw rod is slidably connected to a partition board, and a sliding frame is installed on the support frame.

[0011] Preferably, grooves are formed on both sides of the counterweight block, and inserting plates are slidably connected to the grooves.

[0012] The beneficial effects of the utility model are as follows:

[0013] The motor a and the hydraulic cylinder a cooperate to drive the counterweight block above the counterweight block to be replaced to move upward, which can facilitate the replacement of the counterweight block; the counterweight block is installed inside the counterweight frame, and adjacent counterweight blocks are connected by convex blocks. When a certain counterweight block is damaged, the nut on the inserting rod below the baffle is loosened. After loosening, the electric push rod in the shock-absorbing box shortens to drive the inserting rod to separate from the baffle. After separation, the motor b installed at the top plate rotates to drive the baffle connected to the rotating shaft to rotate outward and separate from the counterweight block, exposing the inner counterweight block. The motor a on the support frame rotates to drive the inserting plate connected to the screw rod to move upward. The inserting plate continuously moves upward to correspond to the grooves formed on both sides of the counterweight block above the counterweight block to be replaced. After corresponding, the hydraulic cylinder a on the partition board shortens to drive the support frame and the sliding frame to slide inward. The inward sliding of the support frame drives the connected inserting plate to slide inward and insert into the groove. After insertion, the hydraulic cylinder b on the partition board shortens to drive the connected pressing plate to move upward, leaving enough clearance. The motor a continuously rotates to drive the inserting plate connected to the screw rod to move upward. The inserting plate abuts against both sides of the counterweight block. The upward movement of the inserting plate drives the counterweight block above the counterweight block to be replaced to move upward, so that the convex block on the counterweight block to be replaced is separated from the upper counterweight block and there is a certain clearance. After separation, the counterweight block to be replaced is lifted upward, so that the convex block on the lower counterweight block is separated from the counterweight block to be replaced and then taken out. After taking out, the counterweight block is replaced. After replacement, the motor a rotates in reverse to drive the cross plate to move downward, that is, to drive the upper counterweight block to move downward and stick to the replaced counterweight block. The hydraulic cylinder b extends to push the pressing plate to move downward for pressing. The motor b rotates in reverse to drive the baffle to rotate inward to block the counterweight block, which can drive the counterweight block above the counterweight block to be replaced to move upward, thereby replacing the counterweight block, and the replacement is convenient.

[0014] The components inside the shock-absorbing box cooperate to achieve a good shock-absorbing and buffering effect; a shock-absorbing box is installed below the counterweight frame. A shock-absorbing plate is slidably connected inside the shock-absorbing box. When the counterweight frame continues to move downward and contacts the ground or other places, the shock-absorbing plate first contacts the ground and then slides into the shock-absorbing box, compressing the spring b between the counterweight frame and the shock-absorbing plate. The spring b wants to return to its original state and gives an outward force to the shock-absorbing box, which can achieve a certain shock-absorbing and buffering effect. The shock-absorbing plate continues to move inward and adheres to the damping rod installed on the counterweight frame. The material of the damping rod is damping copper alloy. Under the action of external stress, due to the movement of micro-twin boundaries and the deflection of magnetic moments, it absorbs external energy, thereby relaxing the stress and achieving a good shock-absorbing and noise-reducing effect, which can prevent the shock-absorbing frame from directly contacting the ground and causing damage to the counterweight block.

[0022] Example 1 Please refer to Figures 1-5As shown in the figure, an elevator counterweight structure includes a counterweight frame 5. The counterweight frame 5 is fixedly connected with a partition plate 6. There are rollers (not shown in the figure) on both sides of the counterweight frame 5. The counterweight frame 5 can fix the position of the partition plate 6. The partition plate 6 is equipped with a hydraulic cylinder a18. The partition plate 6 can fix the position of the hydraulic cylinder a18. The hydraulic cylinder a18 is equipped with a moving frame 4. The telescopic movement of the hydraulic cylinder a18 drives the connected moving frame 4 to move outwards or inwards. The moving frame 4 is rotatably connected with a screw rod 21. The screw rod 21 is threadedly connected with a plug plate 22. The rotation of the screw rod 21 drives the connected plug plate 22 to move. A distance measuring sensor (not shown in the figure) is installed below the partition plate 6, which can detect the position of the plug plate 22. The plug plate 22 is located outside the counterweight block 8. The counterweight frame 5 is equipped with a shock absorption box 9. An electric push rod 23 is installed in the shock absorption box 9. The telescopic movement of the electric push rod 23 drives the connected insertion rod 10 to move outwards or inwards. The electric push rod 23 is equipped with an insertion rod 10. The insertion rod 10 is inserted into a baffle plate 3. The insertion rod 10 is threadedly connected with a nut 16. After the insertion rod 10 is inserted into the baffle plate 3, it is fixed by the nut 16. The baffle plate 3 is rotatably connected with a side plate 2. The counterweight frame 5 is equipped with a damping rod 26. A spring b24 is wound around the damping rod 26. The spring b24 is located between the counterweight frame 5 and a shock absorption plate 15. The spring b24 is equipped with a shock absorption plate 15.

[0023] Specifically, a top plate 1 is installed at the top of the counterweight frame 5. Side plates 2 are installed on both sides of the top plate 1, which can facilitate the installation of the baffle plate 3.

[0024] Specifically, a motor b19 is installed below the top plate 1. The rotation of the motor b19 drives the connected rotating shaft 14 to rotate. The output end of the motor b19 is fixedly connected with a rotating shaft 14.

[0025] Specifically, the rotating shaft 14 is equipped with a baffle plate 3. The rotation of the rotating shaft 14 drives the connected baffle plate 3 to rotate. The baffle plate 3 is located outside the counterweight block 8. The baffle plate 3 can shield the outside of the counterweight block 8. Convex blocks 25 are installed at the upper end of the counterweight block 8 and the bottom of the counterweight frame 5. The convex block 25 on the lower counterweight block 8 is inserted into the bottom of the upper counterweight block 8.

[0026] Specifically, a hydraulic cylinder b20 is installed on the partition plate 6. The partition plate 6 can fix the position of the hydraulic cylinder b20. The hydraulic cylinder b20 is equipped with a pressing plate 12. The distance between the pressing plate 12 and the partition plate 6 is large enough to facilitate the replacement of the counterweight block. The telescopic movement of the hydraulic cylinder b20 drives the connected pressing plate 12 to move downwards or upwards. A spring a17 is installed on the pressing plate 12. The spring a17 is located between the partition plate 6 and the pressing plate 12.

[0027] Specifically, grooves 11 are formed on both sides of the counterweight block 8. The grooves 11 formed on the counterweight block 8 can facilitate the entry and lifting of the plug plate 22. The plug plate 22 is slidably connected with the grooves 11.

[0028] Example 2: Please refer to Figures 1-3 , the difference between this embodiment and Embodiment 1 is that: a motor a13 is installed on the support 4, the support 4 can fix the position of the motor a13, the output end of the motor a13 is fixedly connected with a screw rod 21, and the rotation of the motor a13 drives the connected screw rod 21 to rotate. The screw rod 21 is slidably connected with a partition plate 6, and the screw rod 21 can slide inside and outside along the partition plate 6 and the counterweight frame 5. A sliding frame 7 is installed on the support 4, and the movement of the support 4 drives the connected sliding frame 7 to slide outside the counterweight frame 5.

[0029] When the utility model is in use, the counterweight block 8 is installed inside the counterweight frame 5, and adjacent counterweight blocks 8 are connected by bump blocks 25. When a certain counterweight block 8 is damaged, loosen the nut 16 on the insertion rod 10 below the baffle 3. After loosening, the electric push rod 23 in the shock absorption box 9 shortens to drive the insertion rod 10 to separate from the baffle 3. After separation, the motor b 19 installed on the top plate 1 rotates to drive the baffle 3 connected to the rotating shaft 14 to rotate outwards and separate from the counterweight block 8, exposing the inner counterweight block 8. The motor a 13 on the moving frame 4 rotates to drive the insertion plate 22 connected to the screw rod 21 to move upwards. The insertion plate 22 continuously moves upwards to correspond to the grooves 11 opened on both sides of the counterweight block 8 above the counterweight block 8 to be replaced. After corresponding, the hydraulic cylinder a 18 on the partition plate 6 shortens to drive the moving frame 4 and the sliding frame 7 to slide inwards. The inward sliding of the moving frame 4 drives the connected insertion plate 22 to move inwards and insert into the groove 11. After insertion, the hydraulic cylinder b 20 on the partition plate 6 shortens to drive the connected pressing plate 12 to move upwards, leaving enough clearance. The motor a 13 continuously rotates to drive the insertion plate 22 connected to the screw rod 21 to move upwards. The insertion plate 22 abuts against both sides of the counterweight block 8. The upward movement of the insertion plate 22 drives the counterweight block 8 above the counterweight block 8 to be replaced to move upwards, so that the bump block 25 on the counterweight block 8 to be replaced is separated from the counterweight block 8 above and there is a certain clearance. After separation, lift the counterweight block 8 to be replaced upwards, so that the bump block 25 on the lower counterweight block 8 is separated from the counterweight block 8 to be replaced and then taken out. After taking out, replace the counterweight block 8. After replacement, the motor a 13 rotates in reverse to drive the cross plate to move downwards, that is, drive the upper counterweight block 8 to move downwards and stick to the replaced counterweight block 8. The hydraulic cylinder b 20 extends to push the pressing plate 12 to move downwards for pressing. The motor b 19 rotates in reverse to drive the baffle 3 to rotate inwards to block the counterweight block 8, and can drive the counterweight block 8 above the counterweight block 8 to be replaced to move upwards, so as to replace the counterweight block 8. The replacement is convenient. A shock absorption box 9 is installed below the counterweight frame 5. A shock absorption plate 15 is slidably connected in the shock absorption box 9. When the counterweight frame 5 continuously moves downwards and contacts the ground or other places, the shock absorption plate 15 first contacts the ground and then slides into the shock absorption box 9, compressing the spring b 24 between the counterweight frame 5 and the shock absorption plate 15. The spring b 24 wants to return to its original state and gives an outward force to the shock absorption box 9, which can play a certain shock absorption and buffering effect. The shock absorption plate 15 continuously moves inwards and abuts against the damping rod 26 installed on the counterweight frame 5. The material of the damping rod 26 is damping copper alloy. Under the action of external stress, it absorbs external energy due to the movement of micro twin grain boundaries and the deflection of magnetic moments, so as to relax the stress and play a good shock absorption and noise reduction effect, and can avoid damage to the counterweight block 8 caused by the direct contact between the shock absorption frame and the ground.
