Description

Technical Field

[0001] The invention belongs to the technical field of bridge construction and relates to a traction cable circulation system. Background Art

[0002] The traction system plays a vital role in large-scale construction, bridge construction, material transportation and other fields. As a key component of the traction system, the performance and connection method of the traction rope directly affect the working efficiency and safety of the entire system.

[0003] However, in actual applications, when the entire traction system is composed of multiple sections, the connection between the traction rope strands and the traction system often faces many problems. The traditional connection method is complicated to operate, time-consuming and labor-intensive, and requires professionals to operate for a long time, which seriously affects the construction progress. Moreover, the stability and reliability of the connection are difficult to guarantee, and it is easy to loosen, break and other faults during the traction process, posing a safety hazard to the construction. In addition, due to the inconvenient connection, it also causes great difficulties for the maintenance and replacement of equipment, increasing maintenance costs and downtime.

[0004] There are currently several solutions to the above problems. Some solutions use complex mechanical connection structures. Although the connection is relatively stable, the installation and disassembly process is cumbersome and not conducive to rapid construction. Other solutions rely on specific materials or processes, which are costly and have limited applicability in some harsh environments. In actual applications, it is found that they have strict requirements on the specifications and materials of the traction rope, which limits their wide application.

[0005] The existing solutions have improved the connection problem to a certain extent, but still have the following disadvantages: the operation is complicated and it is difficult to achieve quick connection; the cost is high, which increases the construction cost; the applicability is limited and cannot meet various complex construction conditions.

[0006] In summary, in order to effectively solve the problem of rapid connection between cable strands and a traction cable system when the cable strands are composed of multiple sections and improve construction efficiency, the present invention provides a new traction cable circulation system. Summary of the invention

[0007] The present invention provides a traction cable circulation system, which solves the problem of rapid connection between cable strands and the traction cable system when the entire traction system is composed of multiple sections, thereby improving construction efficiency.

[0008] In order to solve the above problems, the technical solution adopted by the invention is: A traction rope circulation system comprises a traction system and a lifting system. The lifting system comprises a first winch, a lifting rope, and a fastener. There are several winches. The first winch is arranged at the position where the loose rope saddle is anchored and the rope strand is placed. The first winches are connected by the lifting rope. The guide rope is provided with a fastener fixedly arranged on the lifting rope. The lifting rope is fixedly connected to the rope strand through the fastener. It is used to lift the rope strand to the traction system. The traction system comprises a circulating rope, a traction member, and a second winch. The circulating rope is fixedly provided with a traction member, which is used to pull the fastener to fix the rope strand on the circulation system. The fastener and the traction member are both provided with hooks that grip and engage with each other.

[0009] The principle of this solution is that the first winch in the lifting system drives the fastener to rise through the lifting rope, thereby lifting the rope strand to a suitable position, and the traction piece on the circulating rope of the traction system relies on the mutual gripping and engagement with the hook on the fastener to achieve traction and fixation of the rope strand, so that the rope strand can smoothly enter the circulation system, ensuring the stable operation and efficient connection of the entire traction rope circulation system.

[0010] The beneficial effects of this program: By combining the lifting system with the traction system, the cable strand is quickly and stably lifted and connected from the initial position to the traction system. The circulating rope provides a continuous movement path for the traction member, and the hook design on the traction member that engages with the fastener enables the cable strand to be quickly and accurately connected after it reaches the specified position without complicated manual operation, thus greatly saving time and labor costs. The multiple first winches and lifting ropes can adapt to different construction environments and cable strand positions, thus improving the flexibility and versatility of the system, and providing a stable and reliable connection and an efficient traction process, thereby reducing safety risks caused by loose connection or complicated operation, and ensuring the safety of construction personnel. During use, manual intervention is reduced throughout the process, thus reducing safety risks caused by human operational errors.

[0011] Furthermore, the fastener is provided with a semi-open fixing groove, and a limiting block is provided at the open end of the fixing groove. The limiting block is connected with the fastener by rotation, and the upper end of the limiting block is provided with an arc-shaped protrusion structure. The semi-open fixing groove provides a clear fixed position for the cable strand, so that the rotating roller connected to the fixing groove can be placed into the fixing groove. The rotatable limiting block at the open end can effectively prevent the cable strand from coming out, and enhances the reliability of the fixation. When in use, the arc-shaped protrusion is better pressed down by the contact of the connecting piece to release the opening of the semi-open fixing groove, so that the rotating roller on the connecting piece can be better unhooked.

[0012] Furthermore, a fixing piece is provided on the fastener, and the fixing piece is fixed on the lifting cable. The fixing piece and the fastener are connected and fixed by a provided connecting piece. The fixing piece is provided on the lifting cable, and the movement of the lifting cable drives the movement of the fixing piece and the fastener, so that the movement of the lifting cable can be directly and effectively transmitted to the fixing piece and the fastener, ensuring the directness and efficiency of power transmission, reducing energy loss, and improving the operation efficiency of the whole system. At the same time, the movement of the lifting cable can be accurately converted into the movement of the fixing piece and the fastener, and the lifting position and speed of the cable strand can be controlled more accurately, meeting the precision requirements in construction.

[0013] Furthermore, the connecting member is hingedly arranged with the fixing member, and a fixing roller is arranged at the lower end of the connecting member, and the fixing roller is cooperatively connected with the fixing groove, so that the connecting member has greater flexibility and freedom during movement, and it can adapt to the angle changes and position adjustments produced under different working conditions. By cooperating with the fixing roller and the fixing groove, the fixing roller is not easily blocked when unhooking, and thus the unhooking can be performed quickly.

[0014] Furthermore, an arc-shaped protrusion is provided at one end of the connecting member near the limit block, and the arc-shaped protrusion is cooperatively connected with the arc-shaped protrusion on the limit block. The arc-shaped figure provided on the connecting member and the arc-shaped protrusion on the limit block are cooperatively connected, so that the rotation of the connecting member presses the limit block downward through the arc-shaped protrusion, and the opening is released after the limit block is pressed down.

[0015] Furthermore, the hooks arranged on the traction member and the fastener are located on the same horizontal plane. Since the hooks are located on the same horizontal plane, they can accurately engage with each other in the shortest possible time, reducing the time for finding and aligning the hooks, thereby greatly improving the speed of connecting the cable strands with the traction system and improving the construction efficiency. At the same time, in the process of traction and lifting the cable strands, the horizontally aligned hooks can evenly share the pulling force, avoiding excessive local force caused by hook position deviation, reducing the risk of hook damage or connection failure, and enhancing the reliability of the entire system.

[0016] Furthermore, a locking pin is provided on the hook, which is connected with the hook. When the hooks are engaged with each other to complete the connection, the presence of the locking pin can prevent the hook from being accidentally disengaged, especially under complex working conditions such as severe vibration, impact or tension changes, thereby effectively avoiding the risk of loose connection or disconnection.

[0017] Furthermore, a roller is arranged on the lifting frame, and the roller is arranged on the cable strand and is rotatably connected with the cable strand, so as to reduce the wear of the cable strand during the lifting process, and at the same time reduce the resistance encountered by the cable strand during the lifting and moving process, thereby reducing energy consumption and improving the working efficiency of the lifting system.

[0018] Furthermore, a first sensor and a second sensor are provided at the lower end of the fixed platform, and both the first sensor and the second sensor are contact sensors. The first sensor is provided in contact with the fixed part, and the second sensor is provided in contact with the traction part. The first sensor and the second sensor are electrically connected to the first hoist and the second hoist, respectively. Through the contact between the first sensor and the fixed part and the contact between the second sensor and the traction part, the position and state information of the fixed part and the traction part can be sensed in real time and accurately to avoid the fastener and the traction part from over-travel. The first sensor and the second sensor are electrically connected to the first hoist and the second hoist, respectively, to realize real-time feedback control. When the sensor detects that the position of the fixed part or the traction part reaches a preset threshold or an abnormal situation occurs, it can quickly send a signal to the corresponding hoist, and timely adjust the start and stop of the hoist, thereby ensuring that the lifting and traction operations of the rope strand are carried out safely, smoothly and efficiently.

[0019] Furthermore, the hook is provided with a third contact sensor, which is electrically connected to the second winch. When the hook successfully contacts and engages, the third contact sensor can immediately detect this state and transmit a signal to the second winch. This enables the second winch to respond quickly, start or adjust the traction action in time, ensure the timeliness and accuracy of the traction work, and improve work efficiency. At the same time, if the hook is abnormally separated or has poor contact during the traction process, the third contact sensor can quickly detect it and send a signal to the second winch, so that the second winch stops in time or takes corresponding safety measures, avoiding accidents caused by hook connection problems and effectively protecting the safety of personnel and equipment.

DETAILED DESCRIPTION

[0021] The figure marks in the drawings of the specification include: traction system 1, loose rope saddle anchor 2, first winch 3, lifting rope 4, fixed platform 5, lifting bracket 6, pulley 7, hook 8, locking pin 9, fastener 10, fixing part 11, connecting part 12, protrusion 13, limit block 14, limit groove 15, first sensor 16, second sensor 17, tower column 18, second winch 19, traction part 20, rotating shaft 21, fixing groove 22, lifting system 23, rope strand 24, opening 25, rotating roller 26, third contact sensor 27, circulating rope 28.

[0022] The embodiment is basically as shown in the attached Figure 1-4 As shown, the traction rope circulation system includes a traction system 1 and a lifting system 23. In the lifting system 23, a first hoist 3 is arranged at the ground position of the loose rope saddle anchor 2 and the rope strand 24. The first hoist 3 is fixed to the loose rope saddle anchor 2 through a fixing platform 5 at the position of the loose rope saddle anchor 2. At the same time, a first hoist 3 is also arranged at the position of the rope strand 24. The first hoists 3 are connected by a lifting rope 4. A fastener 10 is fixed on the lifting rope 4. When operating, the end of the rope strand 24 is placed on the fastening platform. The first winch 3 is fixed in the part 10 by the fastener 10, and the rotating roller 26 arranged on the connecting member 12 is placed into the fixing groove 22 through the opening 25, and the rotating limit block 14 is initially fixed to block the opening 25 to prevent the rotating roller 26 from escaping. After being fixed on the lifting rope 4 by the fixing member 11, the lower end of the fixing member 11 is hinged to the connecting member 12. When the first winch 3 is working, the fixing member 11 and the fastener 10 are driven to move by the lifting rope 4, so that the lifting rope strand enters the traction system 1.

[0023] The traction system 1 includes a circulating rope 28, a traction member 20 and a second winch 19. The traction member 20 is fixedly arranged on the circulating rope 28, and the traction member 20 and the fastener 10 are both provided with hooks 8 that grip and engage with each other, and the hooks 8 are located on the same horizontal plane. When the rope strand 24 is lifted to a suitable position, the hook 8 on the traction member 20 engages with the hook 8 on the fastener 10, and to ensure a firm connection, a locking pin 9 is provided on the hook 8. The provided hook is a James coupler, which can automatically connect the hook when a vehicle approaches, thereby greatly improving the efficiency and convenience of the connection and reducing the time and labor intensity of manual operation.

[0024] An arc-shaped protrusion 13 is provided at one end of the connecting member 12 near the limit block 14. When the connecting member 12 rotates, the arc-shaped protrusion 13 presses the limit block 14 downward to make way for the opening 25 of the fixing groove 22, so that the fixing roller on the connecting member 12 cooperates with the fixing groove 22 to achieve unhooking.

[0025] A lifting frame bracket 6 is provided on the loose cable saddle anchor 2, and a pulley 7 is provided on the lifting frame. The pulley 7 is rotatably connected with the cable strand 24 to reduce resistance and wear when the cable strand 24 is lifted and moved.

[0026] In addition, at the lower end of the fixed platform 5, a first sensor 16 and a second sensor 17 are provided, both of which are contact sensors. The first sensor 16 is in contact with the fixed part 11, and the second sensor 17 is in contact with the traction part 20. The first sensor 16 and the second sensor 17 are electrically connected to the first winch 3 and the second winch 19 respectively. When the sensor detects that the position of the fixed part 11 or the traction part 20 reaches a preset threshold, a signal is sent to the corresponding winch.

[0027] A third contact sensor 27 is provided on the hook 8, and the third contact sensor 27 is electrically connected to the second winch 19. When the hook 8 is successfully engaged or abnormally separated or has poor contact, the third contact sensor 27 transmits a signal to the second winch 19, and the second winch 19 starts and stops in time to ensure the safety and efficiency of the traction work.

[0028] Through the coordinated work of the above components, the traction cable circulation system realizes the rapid and stable connection between the cable strand 24 and the traction cable circulation system, thereby improving the construction efficiency and safety.

[0029] Specifically, when in use, first, the fastener 10 is fixed to the cable strand 24, and the rotating roller 26 on the connecting member 12 is pressed down through the limit block 14. The limit block 14 is rotated and pressed down into the groove under the action of the rotating shaft 21. After that, the rotating roller 26 is connected with the fixing groove 22 on the fastener 10 through the opening 25. Then, the limit block 14 rebounds and resets, and then the first lifting rope 4 is started. When the first lifting rope 4 rises to the traction system 1, the hook 8 on the traction member 20 is engaged with the hook 8 on the fastener 10. The hook 8 is fastened and fixed to achieve fast engagement, and the third contact sensor 27 provided on the hook 8 receives a signal, the second winch 19 starts to start, and the traction block moves away from the direction of the loose cable saddle anchor 2. During the movement, when the fixing member 11 on the lifting cable 4 contacts the first contact sensor, the first winch 3 stops working. When the first winch 3 stops, the connecting member 12 and the rotating roller 26 do not apply force to the fastener 10. At this time, the fastener 10 is subjected to the pulling force of the traction member 20. At this time, due to the connection member 12 The connecting member 12 is hinged with the connecting member 12. Due to the movement of the traction member 20, the stop of the connecting member 12 causes the connecting member 12 to rotate, thereby driving the arc-shaped protrusion 13 on the connecting member 12 to first contact the limit block 14 and press it down. Due to the inclination of the connecting member 12 and the limit block 14 of the opening 25 being pressed down, the rotating roller 26 is pulled out from the position of the opening 25 to achieve rapid unhooking. When the traction member 20 in the traction system 1 moves to the loose cable saddle anchor 2 by the traction of the second winch 19, the second sensor 17 is provided at the terminal of the traction system 1. When the second contact sensor contacts the traction member 20, the second winch 19 is closed to prevent the traction member 20 from exceeding the stroke and causing danger. Similarly, the first sensor 16 in the lifting system 23 can recognize that the cable strand 24 can be quickly and safely pulled to the tower column 18 repeatedly to install the cable strand 24. In this process, the lifting system 23 and the traction system 1 are uninterrupted during operation, and the lifting system 23 and the traction system 1 are connected when there is no pause, thereby improving work efficiency.
