Description

Technical Field

[0001] This invention relates to a traction device and a bridge rotation operation method, and more particularly to an intelligent continuous traction device and a bridge rotation operation method, belonging to the field of bridge engineering technology. Background Technology

[0002] In bridge construction, large traction forces are often required for operations such as horizontal and vertical rotation of bridges. Traditional traction control systems do not have displacement sensors installed on the main jack; instead, they rely on multiple proximity switches to detect the main jack's position. This method involves numerous components, complex installation, and the inability to monitor the real-time position of the traction jacks during extension and retraction, hindering synchronized control of two jacks. This can lead to discontinuous traction actions and shock vibrations. Inaccurate traction jack position control during anchor pre-loosening and pre-tightening can easily damage the clamping plates or prevent the force from being transferred to the clamping device of another jack. Relying solely on proximity switch signals as the basis for determining clamping or releasing conditions is risky; if the proximity switches malfunction, the system may misjudge the situation, executing incorrect actions and causing serious safety consequences.

[0003] Currently, traction equipment uses anchors to clamp or release steel strands, relying on spring force to press against clamping plates to hold the strands. However, the clamping force of the springs is unstable. When the spring force fails or is insufficient, the clamping plates may not hold the strands firmly enough, causing the strands to slip during traction, resulting in a loss of traction force and potentially causing the lifted load to fall – a serious safety accident. Currently, traction equipment lacks a safety valve block. In the event of emergencies during construction, such as sudden power outages, pump station hydraulic pressure failure, or oil pipe rupture, the absence of a valve block can easily cause the main jack piston to retract, preventing hydraulic pressure locking and posing a risk of the lifted load falling, potentially leading to serious construction safety problems. Furthermore, existing conventional jack devices cannot meet the needs of seamless, continuous traction, exhibiting poor movement progress and control accuracy, and posing certain safety hazards. These technical problems have not yet been effectively resolved. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings and deficiencies of conventional jack devices, which cannot meet the needs of alternating seamless continuous traction, have poor motion progress and control accuracy, and pose certain safety hazards. This invention patent provides a reasonably structured, continuously traction device composed of multiple traction devices connected in series, capable of alternating seamless continuous traction. It improves the motion progress and control accuracy, and the active clamping of the steel strand ensures that the steel strand always maintains a stable clamping force, avoiding the risk of slippage.

[0014] A bridge rotation operation method using intelligent continuous traction equipment, characterized by the following steps: a. First, install the intelligent continuous traction equipment; fix the third support plate, connect one end of the steel strand to one end of the bridge beam that needs to be rotated, and after the front traction device and the rear traction device cylinders are in place, the automatic clamping device will automatically release. b. Then install the traction cable steel strand; after passing the traction cable steel strand through the hole of the third support plate, first pass the steel strand through the guide tube on the directional guide assembly in an orderly manner, then through the first clamping plate hole of the automatic clamping device, and then through the clamping plate tensioning guide. The same steps are repeated in sequence for the automatic clamping device of the traction device and the automatic tool anchor assembly. c. After the traction cable steel strand is installed, the traction equipment is installed and fixed on the reaction pier. After receiving the start operation command, the large piston on the front traction device begins to extend, pushing the automatic clamping device on the front traction device to move the steel strand backward. d. After the front traction device moves into position, the automatic clamping device on the rear traction device clamps the traction cable strand. After detecting the signal, the large piston of the rear traction device begins to extend, pushing the automatic clamping device on the rear traction device to move the strand backward.

[0015] The beneficial effects of this invention are: 1. This invention employs a continuous traction device consisting of multiple traction devices connected in series, which can be seamlessly and alternately connected. The device automatically clamps or releases the steel strand through clamps, and actively clamps the steel strand to maintain a stable clamping force, avoiding the risk of slippage and ensuring that the front and rear jacking forces can be smoothly and seamlessly alternated, achieving the effect of uninterrupted transmission of jacking force.

[0016] 2. This invention employs a detection and feedback system composed of multiple sensors, which can monitor the status in real time during traction and record information such as oil pressure, displacement, and traction force of the pump station and traction equipment throughout the entire working process, thus realizing closed-loop control.

[0017] 3. The detection and feedback system of this invention forms a closed-loop control with the pump station oil pump frequency converter, achieving precise synchronization. Seamless connection is achieved between the front and rear support, ensuring the stability and smoothness of the traction force during the bridge rotation process, without impact or vibration, and realizing synchronous dual control of pressure and displacement.

[0018] 4. The present invention uses the spring of the automatic tool anchor assembly to keep the steel strand from retracting, ensuring that the traction steel strand is always clamped. Even when the jack is without oil pressure, the clamps of the automatic tool anchor assembly can always clamp the steel strand, avoiding the risk of the traction load falling or the slope sliding, and providing double protection for the jacking or traction of heavy loads during construction.

[0048] The bridge rotation operation method of the present invention is as follows: First, install the intelligent continuous traction device and fix the third support plate 3. Connect one end of the steel strand to one end of the bridge beam to be rotated. After the front traction device 5 and the rear traction device 6 are in position, loosen the spring limit plate 12 of the automatic clamping device 10 so that the first clamp 20 is automatically released. Then, pass the traction cable steel strand through the hole of the third support plate 3.

Repeat the same steps to the automatic clamping device 10 of the rear traction device 6, and finally through the automatic tool anchor assembly 24. After the traction cable steel strand is installed, the traction equipment is installed and fixed on the reaction pier. Upon receiving the start-up command, the clamping piston 14 of the clamping cylinder 13 of the front traction device 5 begins to retract downward through the adjusting rod 16, driving the spring limit plate 12 downward. After the spring limit plate 12 presses against the first clamping plate 20 hole to clamp the steel strand, the large piston 34 of the front traction device 5 begins to extend, pushing the automatic clamping device 10 on the front traction device 5 to move the steel strand backward.

After the spring limit plate 12 presses against the first clamping plate 20 hole to clamp the steel strand...

[0049] After the automatic clamping device 10 of the rear traction device 6 clamps the steel strand, upon receiving a signal from the second sensor 45, the large piston 34 of the rear traction device 6 begins to extend, pushing the automatic clamping device 10 on the rear traction device 6 to move the steel strand backward. At the same time, the clamping piston 14 of the clamping cylinder 13 of the front traction device 5 begins to slide upward against the spring limiting plate 12 via the adjusting rod 16. The spring limiting plate 12 drives the first spring 19 to release the steel strand from the first clamping plate 20 hole. Then, the large piston 34 of the front traction device 5 begins to retract, causing the automatic clamping device 10 to retract. After moving to a certain position, the second sensor 45 senses the signal and begins to repeat the previous clamping action of the steel strand. After the first sensor 44 of the rear traction device 6 sends a signal, the traction action begins.

At the same time, the clamping piston 14 of the clamping cylinder 13 of the rear traction device 6 begins to slide upward against the spring limiting plate 12 via the adjusting rod 16. The spring limiting plate 12 drives the first spring 19 to release the steel strand from the first clamping plate 20 hole. Then, the large piston 34 of the rear traction device 6 begins to retract, driving the automatic clamping device 10 to retract. After moving to a certain position, the second sensor 45 senses a signal and begins to repeat the previous clamping action of the steel strand. After the first sensor 44 of the front traction device 5 sends a signal, the traction action begins. By repeating the above actions, the bridge rotation construction is completed.
