Description

Technical Field

[0001] The present invention belongs to the technical field of box girder transportation, and more specifically, relates to a cutting box girder positioning and transporting device and a construction method. Background Art

[0002] In bridge engineering, bridge deck cutting and hoisting is a common operation, usually used in the maintenance, reinforcement or demolition stages of bridges. The process involves precise cutting of the bridge deck, and using hoisting equipment to remove the cut bridge deck section from its original location and transport it to a designated location. Among them, after the cutting is completed, how to accurately and safely lift the bridge deck section and place it on the transport vehicle is one of the key links in the entire operation process. However, the existing hoisting operation method has many shortcomings, especially in the positioning process of the cut bridge deck falling onto the transport vehicle frame. The traditional method relies on manual traction to assist in completing the positioning and placement of the bridge deck, which not only increases labor costs, but also has low work efficiency. At the same time, due to the lack of a buffer structure, the cut bridge deck is prone to impact the transport vehicle during the falling process, which in turn causes damage to the vehicle and even causes safety accidents.

[0003] In response to the above problems, the industry currently mainly adopts the following technical means to deal with them: In terms of hoisting equipment design, some solutions attempt to improve the stability of the bridge deck during lifting by adding a multi-point lifting structure, thereby reducing the possibility of the bridge deck swaying in the air; secondly, in the docking process of the transport vehicle, some studies have proposed the use of laser positioning systems or infrared guidance devices to improve the accuracy of the bridge deck landing and reduce manual intervention; in addition, in order to alleviate the impact force that may be generated during the falling of the bridge deck, some studies have also attempted to install simple spring shock absorbers on the transport vehicle load platform to absorb some of the kinetic energy.

[0004] Despite various tentative solutions, existing technologies still have obvious defects in the following aspects: existing lifting devices still rely on a lot of manual participation, especially when the bridge deck is slowly lowered to the transport vehicle, workers need to continuously pull the bridge deck to ensure its accurate placement. This method is not only labor-intensive, but also poses a major safety hazard; secondly, although some technologies have introduced laser or infrared positioning systems, due to the heavy weight and large volume of the bridge deck and the complex on-site environment, these high-precision positioning devices are often difficult to operate stably in actual applications, and the positioning effect is limited; in addition, the buffering capacity of existing buffer devices is limited, so it is difficult to play a role in protecting the transport vehicle.

[0061] Another aspect of the present invention provides a construction method of a positioning and transporting device for cutting box beams, which is implemented using the positioning and transporting device described above and includes the following steps:

[0062] S1: Mark the installation positions of four clamping seats on the transport vehicle frame according to the distance between the two guide seats in the horizontal direction and the center line of the transport vehicle frame. Then, lay several wooden blocks at equal distances on the upper end of the transport vehicle frame.

[0063] S2: Move the two moving vehicles to both sides of the transport vehicle frame, and adjust the height of the clamping seat to the installation height by the hydraulic push rod according to the height of the clamping seat installation position from the ground. Then, control the moving vehicles to move until the clamping seat clamps the transport vehicle frame, and rotate the adjustment handle to ensure a stable connection between the clamping seat and the transport vehicle frame.

[0064] S3: Starting the air pump to pump air into the vertical main rod through the first and second air ducts, so that the movable vertical rod is pushed upward by the internal air pressure and the telescopic rod is synchronously extended by the movable bearing rod. After the locking groove rises to the upper end of the vertical main rod, the push rod of the electric push rod is pushed out to relax the wire rope. At the same time, the second spring is reset to push the locking rod into the locking groove, thereby locking and fixing the movable vertical rod.

[0065] S4: The support column is driven to descend in height by the hydraulic push rod, so that sufficient buffer height is reserved between the guide seat and the limit jacking block above. After that, the box beam is hoisted into the combined frame constructed by the four placement seats and the four centering clamping plates and kept in a suspended state. The positions of the two placement seats are adjusted by synchronously adjusting the two servo motors on the mobile vehicle, and the positions of the four centering clamping plates are adjusted by synchronously driving the two drive motors to achieve the centering clamping and positioning of the box beam.

[0066] S5: Activate the electric push rod to stretch the steel wire rope, so that the second spring is compressed and pulls the locking rod out of the locking groove. Then, slowly lower the box beam vertically. At the same time, open the exhaust valve. The first buffer spring, the second buffer spring, the buffer rubber block, the resistance-increasing telescopic rod and the third buffer spring cooperate to absorb the impact energy of the box beam on the device and the transport vehicle frame when it is lowered, ensuring that the box beam is stably placed on the upper end of the square timber.

[0067] S6: After the box beam is placed on the transport vehicle frame, the servo motor and the drive motor are driven to move the placement seat and the center clamping plate away from the box beam. At the same time, the insertion rod is disengaged from the slot by pulling the pull rod ring and the movable pad block is pushed to lock the insertion rod position, so that the connecting rod is separated from the clamping seat. After that, the hydraulic push rod is activated to lift the support base off the ground, and the mobile vehicle is controlled to move away from the box beam area, so that the cut box beam is tied and fixed to the transport vehicle frame by the tying rope.

[0068] S7: Connect the new clamping seat to the connecting rod, and repeat steps S1 to S6 to complete the lifting operation of all box girders.

[0069] Furthermore, in step S2, the positioning adjustment unit is in an initial state where the guide seat is in contact with the limit lifting block and the support base is not touching the ground;

[0070] If the installation height of the clamping seat is not less than the height from the limit lifting block to the bottom surface of the support base, the guide seat is driven down or up by the hydraulic push rod to adjust the height of the clamping seat connected to the connecting rod to the installation height;

[0071] If the installation height of the clamping seat is less than the height from the limit lifting block to the bottom surface of the support base, the guide seat is driven down by the hydraulic push rod to make the support base touch the ground, and the height of the clamping seat is adjusted to the installation height by manually compressing the second buffer spring and the third buffer spring;

[0072] The installation height of the clamping seat is greater than the height from the limiting lifting block to the bottom end surface of the support base when the second buffer spring and the third buffer spring reach the compression limit.

[0073] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0074] 1. The positioning and transferring device of the present invention is achieved by arranging two groups of the mobile vehicles and the positioning and adjusting units in a mirror-symmetrical manner on both sides of the transport vehicle frame; utilizing the combined frame composed of the two positioning and adjusting components to stably receive the hoisted cut box beam and adjust the posture of the box beam to be aligned with the transport vehicle frame; utilizing the buffer component in conjunction with the lifting machinery to stably lift the box beam straightly to the upper end of the transport vehicle frame, thereby realizing systematic coordinated control of the lifting, positioning, buffering and fixing operation links, significantly reducing the degree of manual participation and safety risks during the operation process, and improving the stability and efficiency of the overall operation.

[0075] 2. The positioning and transferring device of the present invention uses the support component as a basic frame to support other components, and is reliably connected to the clamping component that stably clamps the transport vehicle frame, further enhancing the overall stability and safety of the box girder during lifting and loading, reducing the risk of accidents, and ensuring smooth operation; in addition, by clamping the four clamping components on the transport vehicle frame to set positions, the positions of the two mobile vehicles can be accurately marked, which greatly simplifies the box girder positioning operation process, reduces manual positioning errors and repeated adjustments, and saves time and labor costs. At the same time, this design ensures that the box girder can stably fall to the center position set by the transport vehicle frame, improves the accuracy and reliability of box girder loading, plays a key role in improving overall operation efficiency and ensuring transportation quality, and adapts to the high efficiency, accuracy and safety requirements of box girder lifting and loading operations.

[0076] 3. The positioning and transfer device of the present invention forms a multi-stage synergistic buffer system through a buffer structure composed of multiple buffer springs and buffer rods, and is combined with a pneumatic drive component including the movable vertical rod, the first air duct, the inflation pump, the second air duct and the exhaust valve, thereby significantly improving the overall buffer performance, so that in the process of the box girder being lifted and dropped to the transport vehicle frame, it can effectively absorb the impact force generated during the fall, reduce vibration and fluctuation, and ensure that the box girder falls smoothly and uniformly to the predetermined position; in addition, refined speed control and flexible contact are achieved through gas compression and release of the pneumatic drive component, and the buffer spring and buffer rod jointly bear the kinetic energy absorption in the subsequent stage, further enhancing the dynamic response capability and stability of the system, thereby effectively improving the adaptability and safety of the device under complex working conditions, reducing the impact load on the transport vehicle frame, avoiding equipment damage and positioning deviation, and providing reliable technical guarantee for realizing efficient, safe and accurate bridge deck component transfer operations.

[0077] 4. The positioning and transfer device of the present invention, through the relative positioning and adjustment components on the two mobile vehicles, and the four placement seats and the four centering clamps together form an adjustable load-bearing combined frame, which can adapt to box beams of various specifications and sizes, and significantly improve the versatility and applicability of the device; secondly, the placement seat is driven by the servo motor to perform longitudinal adjustment of the box beam, and the centering clamp is driven by the drive motor to perform transverse adjustment of the box beam, thereby realizing multi-degree-of-freedom coordinated positioning of the box beam; in addition, by providing a guide wheel at the upper end of the placement seat in contact with the box beam, the friction resistance during the adjustment of the box beam can be effectively reduced, further improving the flexibility of displacement adjustment and the convenience of operation.

[0109] Example 2

[0110] like Figure 9 As shown, based on Example 1, Example 2 of the present invention provides a construction method of a cutting box beam positioning and transferring device, comprising the following steps:

[0111] S1: Mark the installation positions of four clamping seats 301 on the transport vehicle frame according to the distance between the two guide seats 202 in the horizontal direction and the center line of the transport vehicle frame. Then, lay a number of wooden blocks at equal distances on the upper end of the transport vehicle frame.

[0112] S2: Move the two mobile carts 1 to both sides of the transport vehicle frame. Adjust the height of the clamping seat 301 to the installation height by the hydraulic push rod 201 according to the height of the clamping seat 301 from the ground. Then, control the mobile cart 1 to move until the clamping seat 301 engages with the transport vehicle frame, and rotate the adjustment handle 302 to ensure a stable connection between the clamping seat 301 and the transport vehicle frame.

[0113] S3: Start the air pump 405, and inject air into the vertical main rod 401 through the first air guide tube 404 and the second air guide tube 406. Under the action of the internal air pressure, the movable vertical rod 403 is pushed upward and the telescopic rod 501 is synchronously extended through the movable bearing rod 505. After the locking groove 409 rises to the upper end of the vertical main rod 401, the push rod of the electric push rod 414 is pushed out to relax the wire rope 415. At the same time, the second spring 413 is reset to push the locking rod 412 into the locking groove 409, thereby locking and fixing the movable vertical rod 403.

[0114] S4: The support column 203 is driven to descend in height by the hydraulic push rod 201, so that sufficient buffer height is reserved between the guide seat 202 above and the limit jacking block 416. After that, the box beam 6 is hoisted into the combined frame formed by the four placement seats 506 and the four centering clamping plates 514 and kept in a suspended state. The positions of the two placement seats 506 are adjusted by synchronously adjusting the two servo motors 502 on the mobile vehicle 1, and the positions of the four centering clamping plates 514 are adjusted by synchronously driving the two drive motors 510, so as to realize the centering clamping and positioning of the box beam 6.

[0115] S5: Start the electric push rod 414 to stretch the steel wire rope 415, so that the second spring 413 is compressed and pulls the locking rod 412 out of the locking groove 409. Then, the box beam 6 is slowly lowered vertically. At the same time, the exhaust valve 407 is opened. The first buffer spring 408, the second buffer spring 419, the buffer rubber block 421, the resistance-increasing telescopic rod 425 and the third buffer spring 426 cooperate to absorb the impact energy of the box beam 6 on the device and the transport vehicle frame when it is lowered, ensuring that the box beam 6 is stably placed on the upper end of the square timber.

[0116] S6: After the box beam 6 is placed on the transport vehicle frame, the servo motor 502 and the drive motor 510 are driven to move the placement seat 506 and the center clamping plate 514 away from the box beam 6. At the same time, the pull ring of the pull rod 209 is pulled to disengage the insertion rod 207 from the slot 304 and the movable pad block 211 is pushed to lock the position of the insertion rod 207, so that the connecting rod 205 is separated from the clamping seat 301. After that, the hydraulic push rod 201 is activated to separate the support base 418 from the ground, and the mobile vehicle 1 is controlled to move away from the box beam 6 area, so that the cut box beam 6 is tied and fixed to the transport vehicle frame by the tying rope.

[0117] S7: Connect the new clamping seat 301 to the connecting rod 205, and repeat steps S1 to S6 to complete the lifting operation of the entire box beam 6.

[0118] Specifically, in step S1, it is necessary to draw a center line on the transport vehicle frame using a measuring ruler based on the predetermined length of the cut box beam 6 and the length of the transport frame, while ensuring that the cut box beam 6 can be placed on the transport frame. The center line corresponds to the center line of the box beam 6 to be placed. At the same time, based on the center line and the distance between the two clamping seats 5 on the same side, the installation points corresponding to the two clamping seats 5 are marked at corresponding positions. After the marking is completed, several wooden blocks are laid at equal distances on the frame.

[0119] Furthermore, in step S2, the positioning adjustment unit is in an initial state in which the guide seat 202 is in contact with the limit lifting block 416 and the support base 418 is not touching the ground; if the installation height of the clamping seat 301 is not less than the height from the limit lifting block 416 to the bottom surface of the support base 418, the guide seat 202 is driven to descend or ascend by the hydraulic push rod 201 so that the height of the clamping seat 301 connected to the connecting rod 205 is adjusted to the installation height;

[0120] If the installation height of the clamping seat 301 is less than the height from the limit lifting block 416 to the bottom surface of the support base 418, the guide seat 202 is driven down by the hydraulic push rod 201 to make the support base 418 touch the ground, and the height of the clamping seat 301 is adjusted to the installation height by manually compressing the second buffer spring 419 and the third buffer spring 426;

[0121] It should be noted that the installation height of the clamping seat 301 is greater than the height from the limiting lifting block 416 to the bottom surface of the support base 418 when the second buffer spring 419 and the third buffer spring 426 reach the compression limit, so as to avoid a serious decrease in the buffering capacity of the buffer assembly 4.

[0122] Specifically, in step S5, after the cut box beam 6 is positioned and fixed, the electric push rod 414 is started to drive the steel wire rope 415 to pull the locking rod 412 to move and disengage from the locking groove 409, and the positioned box beam 6 can be continued to be vertically lowered in cooperation with the automobile crane, so that during the process of lowering the box beam 6, the support base 418 is supported on the ground to bear the force, and at the same time, the exhaust valve 407 is opened to exhaust. As the box beam 6 is lowered, the movable vertical rod 403 is synchronously moved downward to compress the first buffer spring 408 to buffer the impact force, and after the movable vertical rod 403 moves down to the bottom, it pushes the vertical main rod 16 to be synchronously on the first buffer rod 42 0 moves downwardly to compress the second buffer spring 419 to buffer the impact force, and the movable vertical rod 403 moves downward to drive the second buffer rod 427 to rotate and push the pressure plates 424 on both sides to move toward each other in the limiting slide groove 423 to squeeze and compress the resistance-increasing telescopic rod 425 and the third buffer spring 426 in the middle to further buffer the impact force. At the same time, after the movable vertical rod 403 moves completely downward to the bottom, it pushes the first buffer rod 420 to squeeze the buffer rubber block 421 to further reduce the impact force of the box beam 6 when hanging down, ensuring that the cut box beam 6 is stably placed on the wooden blocks on the frame of the transport vehicle, avoiding manual traction and positioning for hanging down, reducing the impact force of the hanging down on the car, and improving efficiency and safety.

[0123] Specifically, in step S6, through the principle of step S4, after the placement seat 506 and the center clamp 514 are separated from the fixed cutting box beam 6, by pulling the pull rod 209 to drive the insertion rod 207 to separate from the slot 304, the first spring 208 is synchronously compressed, and the movable pad block 211 is moved to move in the movable groove 210, so that the movable pad block 211 is inserted into the outside of the pull rod 209 through the pad slot 211a, avoiding the insertion rod 207 from resetting and inserting into the slot 304, thereby facilitating the separation of the entire equipment from the clamping seat 301 and moving the mobile vehicle 1 to move the entire equipment away, and then the cut bridge deck is tied and fixed on the vehicle frame by the binding rope for transportation to the destination.
