Description

Technical Field

[0001] This utility model relates to the field of balancing device technology, specifically to an open bridge pressure balancing device. Background Technology

[0002] A drop bridge is a type of bridge whose span structure can rotate or move, typically built downstream of a river or at the intersection of water and land transportation. Its main function is to open the bridge deck to allow ships to pass, and then close it again after the ships have passed. The design of a drop bridge includes both the bridge structure and the mechanical components. The mechanical components are responsible for the opening and closing of the bridge deck. A drop bridge's weight balancing device is used to balance the weight changes that occur during the opening process, ensuring the bridge remains stable during both opening and closing.

[0003] The existing bridge pressure balancing device has some drawbacks: First, it is not easy to disassemble and maintain, and once a failure occurs, the repair is difficult and time-consuming; second, the structure is simple, but the stability is lacking and the safety is poor. Utility Model Content

[0004] The purpose of this invention is to provide an opening bridge pressure balancing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A bridge load balancing device includes a support frame and a bridge base plate. The support frame is located at the lower part of the bridge base plate. A counterweight block is located in the middle of the support frame. Both ends of the lower part of the bridge base plate have clearance grooves, and one end of each clearance groove has a locking groove. A support chamber is located in the middle of the upper end of the support frame, and a balance sensor is located at the front of the support chamber. Adjustment chambers are located on both sides of the support chamber. A screw is rotatably connected between the two ends of each adjustment chamber. A motor is located inside the support chamber, and the output end of the motor is fixedly connected to the drive end of the screw. A threaded seat is threaded onto the screw, and a locking block is fixed to the upper end of the threaded seat. The locking block engages with the locking groove. Driven by the motor, the screw rotates, causing the threaded seat and locking block to move within the adjustment chamber. The locking block engages with or disengages from the locking groove, facilitating the installation and disassembly of the device and simplifying the disassembly and maintenance process.

[0006] Preferably, the upper end of the adjustment chamber is provided with a sliding groove, and the sliding groove is slidably connected to the lower end of the locking block. The adjustment chamber limits the locking block through the sliding groove to prevent the locking block from shaking during movement.

[0007] Preferably, the upper end of the counterweight is hinged to an ear plate, and the upper end of the ear plate is connected to a movable column.

[0008] Preferably, a U-shaped frame is fixed to the lower end of the upper part of the bracket, and the interior of the U-shaped frame is hinged to the movable column. The interior of the U-shaped frame has a rectangular groove, which provides a certain amount of space for the movable column to move. The bracket limits and connects the movable column through the U-shaped frame, which helps to ensure the stability of the counterweight during the rotation process when the counterweight rotates slightly.

[0009] Preferably, ear plates four are fixed at both ends of the counterweight, and ear plate three is fixed at the lower end of the counterweight.

[0010] Preferably, the upper end of the lower part of the bracket is fixed with a second ear plate, and a telescopic hydraulic rod is hinged between the second ear plate and the fourth ear plate. The balance sensor is used to monitor the balance state of the bridge bottom plate in real time, adjust the extension and retraction of the telescopic hydraulic rod, and push the counterweight to rotate, thereby adjusting the balance state of the bridge bottom plate.

[0011] Preferably, a connecting plate is provided at the lower part of the ear plate three, and the middle of the upper part of the connecting plate is hinged to the ear plate three. A shock absorber is provided between the lower end of the connecting plate and the upper end of the lower part of the bracket.

[0012] Preferably, guide rails are provided on both sides of the lower end of the bracket, and guide blocks are provided on both ends of the connecting plate. The guide blocks are slidably connected to the guide rails, and the bracket limits the guide blocks through the guide rails to prevent the connecting plate from shaking or shifting.

[0013] Compared with the prior art, the advantages of this utility model are: easy to disassemble and maintain, and excellent safety;

[0014] (1) Driven by the motor, the screw rotates, which drives the threaded seat and the locking block to move in the adjustment chamber. Since the threads at both ends of the screw are opposite, the threaded seats can move closer or further apart, and the locking blocks cooperate with each other. They can be locked into or disengaged from the locking slot, which is conducive to the installation and disassembly of the device and simplifies the disassembly and maintenance process. In addition, the adjustment chamber limits the locking block through the sliding groove, which prevents the locking block from shaking during the movement, improves the stability when the locking block is engaged with the locking slot, and makes it easy to disassemble and maintain.

[0015] (2) The connecting plate ensures that the counterweight can maintain a certain stability when rotating, while the shock absorber can absorb the vibration and impact generated during rotation, further enhancing the stability and durability of the entire device. In addition, the bracket limits the guide block through the guide rail to prevent the connecting plate from shaking or shifting, ensuring the stability and safety of the entire device, with excellent safety.

[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 An embodiment of this utility model provides: an opening bridge pressure balancing device, including a bracket 6 and a bridge base plate 4. The bracket 6 is located at the lower part of the bridge base plate 4. A counterweight block 17 is provided in the middle of the inside of the bracket 6. Both ends of the lower part of the bridge base plate 4 are provided with relief grooves 1, and one end of the relief groove 1 is provided with a slot 3. A support chamber 9 is provided in the middle of the upper end of the bracket 6, and a balance sensor 16 is provided at the front of the support chamber 9. Adjustment chambers 14 are provided on both sides of the support chamber 9, and a screw 8 is rotatably connected between the two ends inside the adjustment chamber 14. A motor 13 is provided inside the support chamber 9, and the output end of the motor 13 is fixedly connected to the drive end of the screw 8. A threaded seat 7 is threaded on the screw 8, and a locking block 2 is fixed at the upper end of the threaded seat 7, and the locking block 2 is engaged with the slot 3.

[0024] When in use, driven by motor 13, screw 8 rotates, which drives threaded seat 7 and locking block 2 to move in adjustment chamber 14. Since the threads at both ends of screw 8 are opposite, they can drive threaded seat 7 to move closer or further away from each other. Locking block 2 cooperates with each other and can be locked into or released from locking slot 3, which is conducive to the installation and disassembly of the device and simplifies the disassembly and maintenance process.

[0025] The upper end of the regulating chamber 14 is provided with a sliding groove 5, and the sliding groove 5 is slidably connected to the lower end of the locking block 2.

[0026] When in use, the adjustment chamber 14 limits the movement of the locking block 2 through the slide groove 5, so as to prevent the locking block 2 from shaking during movement and improve the stability when the locking block 2 is engaged with the slot 3.

[0027] The upper end of the counterweight 17 is hinged to an ear plate 11, and the upper end of the ear plate 11 is connected to a movable column 10. The lower end of the upper part of the bracket 6 is fixed with a U-shaped frame 12, and the interior of the U-shaped frame 12 is hinged to the movable column 10.

[0028] When in use, the U-shaped frame 12 has a rectangular groove inside, which provides a certain amount of space for the movable column 10 to move, allowing the movable column 10 to adjust its position in the rectangular groove. The bracket 6 limits and connects the movable column 10 through the U-shaped frame 12, which helps to ensure the stability of the counterweight 17 during the rotation process when the counterweight 17 rotates slightly, and prevents imbalance caused by shaking or external force.

[0029] Both ends of the counterweight 17 are fixed with ear plates 23, and the upper part of the lower part of the bracket 6 is fixed with ear plate 25. A telescopic hydraulic rod 24 is hinged between ear plate 25 and ear plate 23.

[0030] In use, the balance sensor 16 is used to monitor the balance status of the bridge bottom plate 4 in real time. When the bridge bottom plate 4 tilts due to uneven load or other factors, the balance sensor 16 can quickly sense it and transmit the signal to the control system. The control system adjusts the extension and retraction of the telescopic hydraulic rod 24 according to the received signal. The two telescopic hydraulic rods 24 cooperate with each other to push the counterweight 17 to rotate, thereby adjusting the balance status of the bridge bottom plate 4, which helps the device to respond quickly and correct the unbalanced state.

[0031] The lower end of the counterweight 17 is fixed with a lug 3 20. A connecting plate 19 is provided at the lower part of the lug 3 20, and the middle of the upper end of the connecting plate 19 is hinged to the lug 3 20. A shock absorber 21 is provided between the lower end of the connecting plate 19 and the upper end of the lower part of the bracket 6.

[0032] In use, the connecting plate 19 ensures that the counterweight 17 can maintain a certain stability when rotating, while the shock absorber 21 can absorb the vibration and impact generated during rotation, further enhancing the stability and durability of the entire device.

[0033] Guide rails 18 are provided on both sides of the lower end of the bracket 6, and guide blocks 22 are provided on both ends of the connecting plate 19, and the guide blocks 22 are slidably connected to the guide rails 18.

[0034] In use, the bracket 6 limits the guide block 22 through the guide rail 18 to prevent the connecting plate 19 from shaking or shifting, thus ensuring the stability and safety of the entire device.

[0035] In this embodiment, the following steps are taken: First, the balance sensor 16 monitors the balance of the bridge deck 4 in real time. When the bridge deck 4 tilts due to uneven load or other factors, the balance sensor 16 can quickly detect the tilt and transmit the signal to the control system. The control system adjusts the extension and retraction of the telescopic hydraulic rods 24 based on the received signal. The two telescopic hydraulic rods 24 cooperate to push the counterweight 17 to rotate, thereby adjusting the balance of the bridge deck 4. This allows the device to respond quickly and correct any imbalance. Simultaneously, the U-shaped frame 12 has a rectangular groove inside, providing sufficient space for the movable column 10 to adjust its position. The bracket 6, through the U-shaped frame 12, limits and connects the movable column 10, ensuring the stability of the counterweight 17 during rotation and preventing imbalance caused by shaking or external forces. Subsequently, the connecting plate 19 ensures the stability of the counterweight 17. The weight 17 maintains a certain degree of stability during rotation, while the shock absorber 21 absorbs the vibration and impact generated during rotation, further enhancing the stability and durability of the entire device. Furthermore, the bracket 6, via the guide rail 18, limits the guide block 22, preventing the connecting plate 19 from shaking or shifting, ensuring the stability and safety of the entire device. Additionally, driven by the motor 13, the screw 8 rotates, causing the threaded seat 7 and the locking block 2 to move within the adjusting chamber 14. Since the threads at both ends of the screw 8 are opposite, the threaded seats 7 can move closer or further apart, and the locking blocks 2 can engage or disengage from the slot 3, facilitating installation and disassembly and simplifying the disassembly and maintenance process. Moreover, the adjusting chamber 14, via the sliding groove 5, limits the locking block 2, preventing it from shaking during movement and improving the stability of the locking block 2 when engaged with the slot 3. In summary, this device is easy to disassemble and maintain, and offers excellent safety.
