Description

Technical Field

[0001] This invention belongs to the field of building technology, specifically relating to a transfer platform for steel truss beams. Background Technology

[0002] Numerous bridge construction projects spanning rivers and straits require efficient and safe transport of large steel truss beams. Currently, the drag-and-pull method is commonly used to erect steel truss beams during bridge construction. This method involves setting up a temporary support structure around the construction site, assembling the steel truss beams using this structure, and finally using a dragging device to pull the assembled beams into place. However, in actual construction, site constraints often limit the use of the drag-and-pull method, as temporary supports cannot be installed on existing ground. Furthermore, in the structural installation of large buildings such as stadiums and convention centers, the transport and installation of steel truss beams, as load-bearing structures, is crucial. Therefore, a simple, rationally designed, and easy-to-use transport platform is needed to meet these construction requirements.

[0003] Patent CN106567337B discloses a steel truss beam transfer platform and its construction method, including: a rotating system set up at the starting point of the transfer and a transportation system extending to the end point of the transfer for translating the steel truss beam; the rotating system includes a circular track and a rotating module installed on the circular track; the transportation system includes a transportation track connected to the circular track and a longitudinally moving trolley set up on the transportation track for transporting the steel truss beam; in use, the assembled steel truss beam is hoisted onto the rotating module, the rotating module is operated to make the rotating module run along the circular track, and when the steel truss beam is rotated to be parallel to the transportation track, a jacking device is used to move it laterally a certain distance so that it is located directly above the transportation equipment; then the jacking device is used to lower the steel truss beam onto the longitudinally moving trolley.

[0004] However, the above-mentioned technical solution requires the laying of a circular track to cooperate with the rotating module to transfer and adjust the orientation of the steel truss beam, which occupies a large area. In addition, after the above-mentioned technical solution adjusts the orientation of the steel truss beam by rotating the trolley on the circular track, it uses a lateral moving trolley to support the steel truss beam after the orientation adjustment, and then uses hoisting equipment to lift the steel truss beam and place it on the longitudinal moving trolley. That is, the steel truss beam after the orientation adjustment needs to be transferred again before it can be placed on the transport track. The above-mentioned technical solution involves multiple transfer devices such as rotating trolley, lateral moving trolley and longitudinal moving trolley. The transfer process is complicated and cannot guarantee that the orientation of the steel truss beam remains unchanged throughout the entire transfer process, thus affecting the subsequent accurate splicing of the steel truss beam. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems of existing transfer devices occupying a large area and having many transfer links, which cannot guarantee that the direction of the steel truss beam remains unchanged during the transfer process, thus affecting the accurate splicing of the steel truss beam.

[0006] To achieve the above objectives, the technical approach adopted by this invention is as follows: A steel truss beam transfer platform is provided, including a direction-adjusting vehicle and hydraulic lifting supports disposed on both sides of the direction-adjusting vehicle; wherein, the direction-adjusting vehicle includes a drive base, an operating platform disposed on the drive base, and a rotating component connected in cooperation with the operating platform; this invention allows the steel truss to be directly mounted at the starting position of the transport track and its direction corrected using the direction-adjusting vehicle, eliminating the need for multiple transfer devices to adjust the orientation of the steel truss, making the operation simple and quick, and eliminating the need for a track for adjusting the orientation of the steel truss beam, thus occupying a small area and saving construction space.

[0007] Specifically, during use, the drive base is moved to the starting point of the transport track, and the steel truss beam is hoisted onto the operating platform using hoisting equipment. Then, the operating platform is rotated intermittently by the rotating component, so that the steel truss beam is parallel to the transport track, thus achieving rapid and accurate correction of the splicing direction of the steel truss beam. After the hydraulic lifting rod supports the steel truss beam, the direction adjustment vehicle is withdrawn, and the steel truss beam is moved to the starting point of the transport track by the propulsion equipment. There is no need to transfer the steel truss beam with the adjusted placement angle again using other transfer devices.

[0008] Based on the above technical concept, the technical solution adopted by this invention is as follows: A transfer platform for steel truss beams, comprising: The steering adjustment vehicle is used to adjust the placement angle of steel truss beams; Two hydraulic lifting supports are located on both sides of the steering adjustment vehicle and are used to adjust the height of the steel truss beam.

[0009] In the above technical solution, the preferred embodiment of the direction adjustment vehicle includes: Mounting rack; The control panel has an I-shaped structure and is fitted into the mounting frame. Rotating components are connected to the control panel and mounting bracket, respectively; The drive base connects to the mounting bracket.

[0010] Further specifying the above technical solution, the rotating component includes: The drive motor is located inside the control panel; Multiple limit modules are arranged in a circular pattern on the bottom surface of the control panel; An eccentric rotary table is located below the control panel and is connected to the output end of the drive motor; The drive linkage is connected to the eccentric rotary disk and the mounting bracket, and the drive linkage is engaged with one of the limit modules.

[0011] To further define the above technical solution, each set of limiting modules includes: a first limiting unit and a second limiting unit disposed adjacent to each other on the bottom surface of the operating table.

[0012] To further define the above technical solution, the drive linkage includes: The first rotating rod is rotatably connected to the first rotating column set on the eccentric rotating disk on its side, and both ends of the first rotating rod are provided with U-shaped grooves, one end of which is used to engage with the first limiting unit, and the other end of which is used to engage with the first limiting rod set on one side of the mounting frame. The sliding rod is slidably connected to the second limiting rod located on the other side of the mounting bracket, and one end of the sliding rod is engaged with the second limiting unit; The second rotating rod has one end rotatably connected to the second rotating column set on the first rotating rod, and the other end rotatably connected to the end of the sliding rod away from the second limiting unit through the third rotating column.

[0013] To further define the above technical solution, the second limiting rod is provided with an inverted T-shaped through hole that is slidably connected to the sliding rod.

[0014] To further refine the above technical solution, an infrared level is installed on the drive base.

[0015] A method for operating a transfer platform for a steel truss beam according to any one of the preceding claims includes the following steps: S1: Move the direction adjustment vehicle to the starting position of the transport track and place the two hydraulic lifting supports on both sides of the direction adjustment vehicle. S2: Hoist the assembled truss beams onto the operating platform and use bolts to lock the steel truss beams to the operating platform to form a whole; S3: The operating table is rotated intermittently by the rotating component so that the steel truss beam on the operating table is parallel to the transport track; S4: After the two hydraulic lifting supports lift the steel truss beam, the steering adjustment vehicle is removed; S5: Use propulsion equipment to advance the steel truss beam to the starting transport position on the transport track to complete the transfer of the steel truss beam.

[0016] Furthermore, in the above technical solution, step S3 includes: S301: Start the drive motor. The drive motor drives the eccentric rotating disk to rotate. The eccentric rotating disk drives the first rotating rod to move through the first rotating column, so that the end of the first rotating rod away from the first limiting rod gradually approaches the first limiting unit until the first rotating rod is engaged with the first limiting unit. At the same time, the first rotating rod drives the sliding rod to move away from the eccentric rotating disk through the second rotating rod; S302: After the first rotating rod engages with the first limiting unit, it drives the operating table to rotate; At the same time, the first rotating rod drives the sliding rod to move towards the side closer to the eccentric rotating disk through the second rotating rod, so that the sliding rod gradually approaches the second limiting unit until the sliding rod engages with the second limiting unit. At this time, the operation table stops rotating and the first rotating rod leaves the first limiting unit. S303: After the first rotating rod leaves the first limiting unit, the first rotating rod continues to rotate, causing the sliding rod to gradually separate from the second limiting unit; At the same time, the end of the first rotating rod that is away from the first limiting rod gradually approaches the first limiting unit again, thus repeating the movement process of steps S301 to S303, so as to realize the intermittent rotation of the operating table of the rotating component, so that the steel truss beam on the operating table is parallel to the transport track. Beneficial effects

[0017] This invention, through the combined design of a direction adjustment vehicle and a hydraulic lifting rod, allows the direction adjustment vehicle to be directly moved to the starting position of the transport track. After adjusting the direction of the steel truss beam, the hydraulic lifting rod can be used to support the steel truss beam, which can then be pushed to the starting point of the transport track by a propulsion device. This eliminates the need for multiple transfers; after adjusting the placement angle, only one transfer is required, and the placement angle of the steel truss beam remains unchanged during the transfer process.

[0018] This invention, through the combined design of a drive base, an operating platform, and a rotating component, requires only hoisting equipment to lift the steel truss beam onto the operating platform. Then, by intermittently rotating the operating platform using the rotating component, the orientation of the steel truss beam on the operating platform can be adjusted. There is no need to lay tracks for adjusting the steel truss beam, resulting in a small footprint and high flexibility. Furthermore, the intermittent rotation of the operating platform prevents it from continuing to rotate under inertia after rotating a certain angle, thus achieving precise correction of the steel truss beam.

[0019] The limiting module provided by the present invention includes a first limiting unit and a second limiting unit; in actual use, the angle of a single rotation of the operating table can be adjusted by adjusting the distance between the first limiting unit and the second limiting unit.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] Furthermore, features limited to "first" and "second" may explicitly or implicitly include one or more of the same feature.

[0027] In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] The inventors discovered the following problems with current transfer devices: 1. A circular track and a rotating module are required to rotate the steel truss beam so that it is parallel to the transport track. Then, a lifting device is used to lower the steel truss beam onto the transport platform for transfer. However, this technical solution requires a circular track and rotating modules to transfer the steel truss beam, which occupies a large area. 2. After adjusting the direction of the steel truss beam by rotating a trolley on the circular track, a lateral moving trolley is used to support the adjusted steel truss beam, and then it is lowered onto a longitudinal moving trolley. This means that the steel truss beam must be transferred again after adjustment before it can be moved onto the transport track. This involves multiple transfer steps and makes it impossible to ensure that the direction of the steel truss beam remains unchanged throughout the entire transfer process.

[0030] Based on the above findings, this application proposes a steel truss beam transfer platform and its usage method, including a direction adjustment vehicle and hydraulic lifting supports 6 on both sides of the direction adjustment vehicle. The direction adjustment vehicle includes a drive base 4, and a mounting frame 1, an operating table 2 and a rotating component 3 disposed on the drive base 4. This invention achieves the following: 1. The steel truss beam 8 only needs to be hoisted and placed on the operating platform 2, and the steel truss beam 8 can be directly rotated by the rotating component 3 connected to the operating platform 2 to adjust the orientation of the steel truss beam 8, so that the steel truss beam 8 is parallel to the transport track 7. This invention does not require the laying of a rotating track, and the orientation adjustment of the steel truss beam 8 can be completed by rotating the operating platform 2, which occupies little construction space. 2. After adjusting the direction of the steel truss beam 8, the steel truss beam 8 can be lifted by the hydraulic lifting support and removed from the operating platform 2. Then, the steel truss beam 8 can be directly pushed to the starting transportation position of the transportation track using the propulsion equipment. The steel truss beam 8 can be moved to the transportation track without multiple transfers, and the orientation of the steel truss beam 8 meets the construction requirements. Example 1

[0031] like Figures 1 to 14 As shown, this embodiment provides a steel truss beam transfer platform, including: a direction adjustment vehicle, and hydraulic lifting supports 6 installed on both sides of the direction adjustment vehicle.

[0032] In actual use, transport track 7 is laid out at the construction site, and the direction-adjusting vehicle is placed at the center of transport track 7, such as... Figure 1 As shown, the transport track 7 provided in this embodiment of the invention consists of two parallel bridge supports, the bottoms of which are deeply buried underground.

[0033] The steering adjustment vehicle includes a mounting frame 1, an operating table 2, a rotating assembly 3, and a drive base 4; The drive base 4 is equipped with a driver for moving the entire device, and an infrared level 5 is also located on the drive base 4. It should be noted that the driver and infrared level 5 on the drive base 4 in this embodiment are existing technologies, and this embodiment does not improve upon them.

[0034] Mounting bracket 1 includes a horizontally arranged square frame and four vertically arranged connecting rods at the corners of the square frame. The upper ends of the four connecting rods are fixedly connected to the direction frame, and the lower ends are fixedly connected to the drive base 4. Specifically, a first limiting rod 11 and a second limiting rod 12 are horizontally arranged on both sides of the square frame of the mounting bracket 1; wherein, the ends of the first limiting rod 11 and the second limiting rod 12 away from the mounting bracket 1 are both used to connect with the rotating component 3, and the second limiting rod 12 is provided with an inverted T-shaped through hole for connecting with the rotating component 3.

[0035] The operating table 2 is fitted into the square frame of the mounting bracket 1, and the operating table 2 and the square frame are rotatably mounted. Specifically, the operating platform 2 has an I-shaped structure, including an upper circular plate 21, a middle column 22, and a lower circular plate 23. The upper end of the middle column 22 is fixedly connected to the upper circular plate 21, and the lower end is fixedly connected to the lower circular plate 23. The upper circular plate 21 is used to place the steel truss beam 8, the middle column 22 is fitted into the mounting frame 1, and the lower circular plate 23 is located below the square frame of the mounting frame 1. It should be noted that this embodiment of the invention does not limit the method of fixing the middle column 22 to the upper circular plate 21 and the lower circular plate 23 respectively; for example, the fixing method is welding.

[0036] The rotating assembly 3 includes a drive motor 31, multiple limit modules 32, an eccentric rotating disk 33, and a drive linkage.

[0037] The drive motor 31 is embedded in the middle column of the operating table 2, and the output end of the drive motor 31 is fixedly connected to the eccentric rotating disk 33 located below the operating table 2.

[0038] The eccentric rotating disk 33 has a circular plate structure, and a first rotating column 33a is provided on the eccentric rotating disk 33. Specifically, the first rotating column 33a is located at a non-center position of the eccentric rotating disk 33, and the first rotating column 33a is used to connect with the drive connecting rod. It should be noted that the rotational connection method between the first rotating column 33a and the drive connecting rod in this embodiment of the invention is prior art, and this embodiment of the invention does not improve it. For example, a circular protrusion is provided on the side of the first rotating column 33a, and correspondingly, an annular groove is provided on the drive connecting rod to match and connect with the circular protrusion.

[0039] Multiple sets of limit modules 32 are disposed on the bottom surface of the lower circular plate of the operating table 2; in use, the multiple sets of limit modules 32 are arranged in a circular pattern with equal spacing on the bottom surface of the lower circular plate of the operating table 2.

[0040] Specifically, each set of limiting modules 32 includes a first limiting unit 32a and a second limiting unit 32b. In actual use, the angle of a single rotation of the operating table 2 can be limited by adjusting the distance between the first limiting unit 32a and the second limiting unit 32b, and the distance between any two adjacent limiting units is equal, that is, the distance between the first limiting unit 32a and the second limiting unit 32b is equal to the distance between two adjacent limiting modules.

[0041] The drive linkage is connected to the first limiting rod 11, the second limiting rod 22, and the eccentric rotating disk 33. Specifically, the drive linkage includes: a first rotating rod 34, a sliding rod 35, and a second rotating rod 36.

[0042] The middle part of the first rotating rod 34 is rotatably connected to the first rotating column 33a; specifically, the center of the first rotating rod 34 is rotatably connected to the first rotating column 33a, and the two ends of the first rotating rod 34 are respectively provided with U-shaped grooves 34b, one end of which is engaged with the lower end of the first limiting rod 11, and the other end of which is engaged with the first limiting unit 32a in the moving state; The first rotating rod 34 has a second rotating column 34a at its center for rotatably connecting with the second rotating rod 36.

[0043] The second rotating rod 36 is a strip structure. One end of the second rotating rod 36 is rotatably connected to the second rotating column 34a, and the other end is located below the second limiting rod 12 and is rotatably connected to the third rotating column 37 set on the bottom surface of the second limiting rod 12. The lower ends of the second rotating column 34a and the third rotating column 37 are both fixedly provided with anti-detachment blocks, which are used to prevent the second rotating rod 36 from detaching.

[0044] The sliding rod 35 is slidably disposed in the inverted T-shaped through hole of the second limiting rod 12. Specifically, one end of the sliding rod 35 is provided with a connecting hole, and the other end is provided with a U-shaped groove. The end of the sliding rod 35 with the connecting hole is rotatably connected to the third rotating column 37, and the end of the sliding rod 35 with the U-shaped groove is located near the end of the second limiting unit 32b so as to engage with the second limiting unit 32b in the motion state.

[0045] The working principle of the direction adjustment vehicle provided in this embodiment of the invention is as follows: After the hoisting equipment hoists the steel truss beam 8 onto the operating platform 2, the drive motor 31 starts and drives the eccentric rotary disk 33 to rotate clockwise. Since one end of the first rotating rod 34 is engaged with the first limiting rod 11 and the other end is rotatably connected to the second rotating rod 36, and the end of the second rotating rod 36 away from the first rotating rod is rotatably connected to the second limiting rod 12 through the third rotating column 37, during the rotation of the eccentric rotary disk 33, the eccentric rotary disk 33 drives the first rotating rod 34 to move left and right through the first rotating column 33a. At the same time, the end of the first rotating rod 34 close to the eccentric rotary disk 33 shifts up and down. During the clockwise rotation of the eccentric rotating disk 33, the eccentric rotating disk 33 drives the first rotating rod 34 to move to the right through the first rotating column 33a, and the end of the first rotating rod 34 near the eccentric rotating disk 33 shifts upward. At this time, the end of the first rotating rod 34 near the eccentric rotating disk 33 gradually approaches the first limiting unit 32a in a certain set of limiting modules 32, and the first rotating rod 34 drives the second rotating rod 36 to move to the right synchronously through the second rotating column 34a. The second rotating rod 36 drives the sliding rod 35 to move to the right synchronously in the inverted T-shaped through hole of the second limiting rod 12 until the first rotating rod 34 is engaged with the first limiting unit 32a. At this time, the sliding rod 35 is located at the position furthest away from the eccentric rotating disk 33. When the first rotating rod 34 engages with the first limiting unit 32a, the first rotating column 33a is located at the position closest to the second limiting rod 12. Then, the first rotating column 33a continues to rotate clockwise under the drive of the eccentric rotating disk 33. At this time, the first rotating rod 34 moves to the left under the drive of the first rotating column 33a, and the end of the first rotating rod 34 near the eccentric rotating disk 33 shifts downward. At this time, after the first limiting unit 32a is pushed by the first rotating rod 34, it moves outward along the inner wall of the U-shaped groove 34b of the first rotating rod 34, so that the first limiting unit 32a drives the operating table 2 to rotate clockwise. The first limiting unit 32a moves outward along the inner wall of the U-shaped groove 34b of the first rotating rod 34 until it disengages from the U-shaped groove 34b. At this time, the first limiting unit 32a is no longer pushed by the first rotating rod 34, and the operating table 2 continues to rotate under the action of inertia. As the first rotating rod 34 moves to the left, the first rotating rod 34 drives the sliding rod 35 to move synchronously to the left in the inverted T-shaped through hole of the second limiting rod 12 through the second rotating rod 36, until the U-shaped groove of the sliding rod 35 engages with the second limiting unit 32b in the same group as the first limiting unit 32a. At this time, the operating table 2 stops rotating, realizing a single rotation of the operating table 2, that is, realizing a single directional adjustment of the steel truss beam 8 located on the operating table 2. While the end of the sliding rod 35 with the U-shaped groove engages with the second limiting unit 32b, the first rotating column 33a is located at the position furthest from the second limiting rod 12. Then, the first rotating column 33a continues to rotate clockwise under the drive of the eccentric rotating disk 33. At this time, the first rotating rod 34 moves to the right under the drive of the first rotating column 33a, and the end of the first rotating rod 34 near the eccentric rotating disk 33 shifts upward. At this time, the end of the first rotating rod 34 near the eccentric rotating disk 33 gradually approaches the first limiting unit 32a in a certain set of limiting modules 32, and the first rotating rod 34 drives the second rotating rod 36 to move to the right synchronously through the second rotating column 34a... This cycle repeats to realize the intermittent rotation of the operating table 2 of the rotating component 3, thereby realizing the intermittent adjustment of the placement angle of the steel truss beam 8 located on the operating table 2. Example 2

[0046] Based on Embodiment 1, this embodiment of the invention also provides a method for using a steel truss beam transfer platform, comprising the following steps: S1: Lay out the transport track 7, move the direction adjustment vehicle to the starting position of the transport track 7, and place the two hydraulic lifting supports 6 on both sides of the direction adjustment vehicle respectively; S2: Hoist the assembled steel truss beam 8 onto the operating platform 2, and use bolts to lock the steel truss beam 8 to the operating platform 2 to form a whole; S3: Rotate the operating table 2 by rotating the rotating component 3 so that the steel truss beam 8 located on the operating table 2 is parallel to the transport track 7; Specifically, this step includes the following steps: S301: Start drive motor 31; In this step, the drive motor 31 drives the eccentric rotating disk 33 to rotate clockwise. Since one end of the first rotating rod 34 is engaged with the first limiting rod 11 and the other end is rotatably connected to the second rotating rod 36, and the end of the second rotating rod 36 away from the first rotating rod is rotatably connected to the second limiting rod 12 through the third rotating column 37, during the rotation of the eccentric rotating disk 33, the eccentric rotating disk 33 drives the first rotating rod 34 to move left and right through the first rotating column 33a. At the same time, the end of the first rotating rod 34 close to the eccentric rotating disk 33 shifts up and down. During the clockwise rotation of the eccentric rotating disk 33, the eccentric rotating disk 33 drives the first rotating rod 34 to move to the right through the first rotating column 33a, and the end of the first rotating rod 34 near the eccentric rotating disk 33 shifts upward. At this time, the end of the first rotating rod 34 near the eccentric rotating disk 33 gradually approaches the first limiting unit 32a in a certain set of limiting modules 32, and the first rotating rod 34 drives the second rotating rod 36 to move to the right synchronously through the second rotating column 34a. The second rotating rod 36 drives the sliding rod 35 to move to the right synchronously in the inverted T-shaped through hole of the second limiting rod 12 until the first rotating rod 34 is engaged with the first limiting unit 32a. At this time, the sliding rod 35 is located at the position furthest away from the eccentric rotating disk 33. S302: After the first rotating rod 34 is engaged with the first limiting unit 32a, it drives the operating table 2 to rotate, thereby realizing a single directional adjustment of the operating table 2; In this step, when the first rotating rod 34 engages with the first limiting unit 32a, the first rotating column 33a is located at the position closest to the second limiting rod 12. Then, the first rotating column 33a continues to rotate clockwise under the drive of the eccentric rotating disk 33. At this time, the first rotating rod 34 moves to the left under the drive of the first rotating column 33a, and the end of the first rotating rod 34 near the eccentric rotating disk 33 shifts downward. At this time, after the first limiting unit 32a is pushed by the first rotating rod 34, it moves outward along the inner wall of the U-shaped groove 34b of the first rotating rod 34, so that the first limiting unit 32a drives the operating table 2 to rotate clockwise. The first limiting unit 32a moves outward along the inner wall of the U-shaped groove 34b of the first rotating rod 34 until it disengages from the U-shaped groove 34b. At this time, the first limiting unit 32a is no longer pushed by the first rotating rod 34, and the operating table 2 continues to rotate under the action of inertia. As the first rotating rod 34 moves to the left, the first rotating rod 34 drives the sliding rod 35 to move synchronously to the left in the inverted T-shaped through hole of the second limiting rod 12 through the second rotating rod 36, until the U-shaped groove of the sliding rod 35 engages with the second limiting unit 32b in the same group as the first limiting unit 32a. At this time, the operating table 2 stops rotating, realizing a single rotation of the operating table 2, that is, realizing a single directional adjustment of the steel truss beam 8 located on the operating table 2. S303: After the first rotating rod 34 leaves the first limiting unit 32a, the first rotating rod 34 continues to rotate, causing the sliding rod 35 to gradually separate from the second limiting unit 32b; At the same time, the end of the first rotating rod 34 that is away from the first limiting rod 11 gradually approaches the first limiting unit 32a again........ This repeats the movement process of steps S301 to S303, so that the rotating component 3 intermittently rotates the operating table 2, making the steel truss beam 8 on the operating table 2 parallel to the transport track 7. Specifically, while the end of the sliding rod 35 with the U-shaped groove engages with the second limiting unit 32b, the first rotating column 33a is located at the position furthest from the second limiting rod 12. Then, the first rotating column 33a continues to rotate clockwise under the drive of the eccentric rotating disk 33. At this time, the first rotating rod 34 moves to the right under the drive of the first rotating column 33a, and the end of the first rotating rod 34 near the eccentric rotating disk 33 shifts upward. At this time, the end of the first rotating rod 34 near the eccentric rotating disk 33 gradually approaches the first limiting unit 32a in a certain set of limiting modules 32, and the first rotating rod 34 drives the second rotating rod 36 to move to the right synchronously through the second rotating column 34a... This cycle repeats to realize the intermittent rotation of the operating table 2 of the rotating component 3, thereby realizing the intermittent adjustment of the placement angle of the steel truss beam 8 located on the operating table 2. S4: After the steel truss beam 8 is placed at the adjusted angle, the two hydraulic lifting supports 6 will lift the steel truss beam 8 and then remove the direction adjustment vehicle. Specifically, the height of each hydraulic lifting bracket 6 is raised to support both ends of the steel truss beam 8, and then the steering adjustment vehicle is withdrawn; S5: Use propulsion equipment to advance the steel truss beam 8 to the starting position of the transport track 7 to complete the transfer of the steel truss beam so that the steel truss beam 8 can be transported to the designated position later.
