[0002] The bent cap refers to the cross beam arranged on the top of the bent pile pier for supporting, distributing and transmitting the load of the upper structure, also known as the cap beam. The cross beam of reinforced concrete or low-reinforced concrete is arranged on the bridge pier (table) or on the row pile. The main function is to support the upper structure of the bridge and transmit all the loads to the lower structure. Some bridges directly connect the bent cap with the pile, and some bridges connect the bent cap with the column after connecting the pile, the main load of the bent cap is the concentrated force transmitted by the beam body above through the support, and the bent cap acts as a bending member, under the action of the load, the bending moment is caused at each section, accompanied by the action of shear force. In addition, the bent cap will also bear the torque and produce torsional shear stress under the action of the construction process and live load. When pouring the bent cap, a cross beam support needs to be erected for supporting the pouring formwork, and a support device needs to be arranged at the bottom of the cross beam support to support the cross beam during the erection of the cross beam support.

[0003] The Chinese patent application file with the authorized publication number CN221501755U discloses a cast-in-place bent cap assembly type steel pipe support. The cast-in-place bent cap assembly type steel pipe support includes a base plate, a support pipe and a steel pipe. The top of the base plate is provided with a support pipe, the top end of the support pipe is provided with a steel pipe, the number of support pipes is multiple, and a reinforcing mechanism is arranged between adjacent support pipes.

[0004] However, the structure design of the above-mentioned related technology: when installing the steel pipe support, although it is not necessary to weld the spliced steel pipes, but during the splicing process of the steel pipes, it is inconvenient to quickly make the holes on the two flanges correspond, the position of the steel pipe needs to be adjusted repeatedly by the workers, so as to make the flanges on the steel pipe correspond accurately, which not only wastes a lot of time, but also consumes too much physical strength of the workers.

[0005] Therefore, a bent cap support erecting device is proposed to solve the problems in the above-mentioned related technology. SUMMARY

[0006] The present application provides a bent cap support erecting device, which aims to solve the problem of inconvenience in quickly making the holes on the two flanges correspond in the related technology.

The support mechanism includes a flange plate 1 provided on the mounting seat, a steel pipe 1 provided inside the flange plate 1, a flange plate 2 provided at the top end of the steel pipe 1, and an adjustment component and a sliding component 1 provided inside both ends of the steel pipe 1. A limiting groove adapted to the limiting mechanism is provided on the flange plate 2. The adjustment assembly includes a fixed column arranged at the top end of a steel pipe, a positioning column installed at the top end of the fixed column, four spiral grooves provided on the fixed column, and four slide grooves provided on the fixed column. The bottom end of the slide groove is located at the same place as the end of the spiral groove, the top end of the slide groove is adjacent to the head end of the spiral groove, the slide groove is connected to the spiral groove, and the top end of the positioning column is tapered.

During splicing, move the hoisted steel pipe to the top of the fixed steel pipe, and then drive the hoisted steel pipe to move down. During the downward movement of the hoisted steel pipe, the mounting ring can be sleeved on the outside of the positioning column. As the hoisted steel pipe continues to move downward, the limit column contacts the outside of the positioning column. At this time, the positioning column presses the limit column into the mounting ring and contacts the inside of the mounting ring, thereby positioning the steel pipe to prevent the steel pipe from tilting. When the mounting ring moves down to the fixed When the lifting column is on the outside of the column, the limiting column is inserted into the spiral groove or slide groove of the fixed column. When the limiting column enters the spiral groove, under the action of the spiral groove, the limiting column can drive the hoisted steel pipe to rotate, so that the limiting column enters the slide groove along the trajectory of the spiral groove. When the limiting column enters the slide groove directly, the hoisted steel pipe moves down along the slide groove and contacts the fixed steel pipe. At the same time, the limiting column moves down along the trajectory of the slide groove, so that the flange one on the hoisted steel pipe one corresponds to the flange two on the fixed steel pipe one, so as to achieve the effect of automatic alignment. There is no need for the staff to manually adjust the steel pipe one.

[0015] When lifting steel pipe one or steel pipe two, put the lifting rope into the groove of the movable plate. At this time, pulling the lifting rope upward can drive the movable plate to move up and contact the inner wall of the lifting ear. At this time, under the action of the movable plate and the lifting ear, the protrusion can be pressed into the movable plate. At this time, the protrusion drives the clamping piece through wedge block one to clamp the lifting rope in the groove.

[0017] When the wedge block moves down, the wedge block 1 drives the tooth plate to approach the rope through the fixed rod on the wedge block 2, so as to clamp the rope in the groove. At the same time, the teeth on the tooth plate can prevent the rope from sliding in the groove.

[0018] Preferably, the articulated assembly includes a connecting rod, a mounting plate, two articulated seats and two articulated arms, the top end of the connecting rod is mounted on the movable plate, the mounting plate is located inside the limiting assembly, the bottom end of the connecting rod is mounted on the mounting plate, and the two articulated seats are respectively mounted on both sides of the bottom of the mounting plate and are hinged to the two articulated arms.

[0021] When the articulated arm moves upward, the two slide bars are driven closer to each other through the two articulated arms, so that the limit block enters the plug plate. When the plug plate enters the second flange and the limit block corresponds to the limit slot, the lifting rope is released. At this time, the movable plate is reset to allow the limit block to be inserted into the limit slot, preventing the unfixed steel pipe one or steel pipe two from being deflected by the influence of the crane or wind.

[0022] By adopting the above technical solution, the beneficial effects of the present invention are as follows: during installation, the flange on one of the steel pipes is first installed on the mounting seat, at this time the first steel pipe is fixed, and then the other steel pipe is lifted to splice the two steel pipes. During splicing, the steel pipe to be lifted is moved above the fixed steel pipe, and then the lifted steel pipe is driven to move down. During the downward movement of the lifted steel pipe, the mounting ring can be sleeved on the outer side of the positioning column. As the lifted steel pipe continues to move downward, the limit column contacts the outer side of the positioning column. At this time, the positioning column presses the limit column into the mounting ring and contacts the inner side of the mounting ring, thereby positioning the steel pipe to prevent the steel pipe from tilting. When the mounting ring moves down to the outer side of the fixed column, the limit column The column is inserted into the spiral groove or slide groove of the fixed column. When the limit column enters the spiral groove, under the action of the spiral groove, the limit column can drive the hoisted steel pipe to rotate, so that the limit column enters the slide groove along the trajectory of the spiral groove. When the limit column enters the slide groove directly, the hoisted steel pipe moves down along the slide groove and contacts the fixed steel pipe.

DETAILED DESCRIPTION

[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figures 1 to 10 As shown, the cap beam support erection device of the present invention includes a supporting mechanism 10, a connecting mechanism 20, a mounting seat 30 and a limiting mechanism 40. There are multiple supporting mechanisms 10, and multiple supporting mechanisms 10 are connected in sequence from bottom to top. In this embodiment, the number of supporting mechanisms 10 is two, and in other embodiments, the number of supporting mechanisms 10 can be three, four or more. The supporting mechanism 10 located at the bottom is connected to the mounting seat 30, and the mounting seat 30 is placed in a concrete base. The mounting seat 30 is provided with a mounting hole that can be connected with a bolt. The connecting mechanism 20 is installed on the top of the supporting mechanism 10 located at the top. There are multiple groups of limiting mechanisms 40, and the multiple groups of limiting mechanisms 40 are respectively arranged on the supporting mechanism 10 and the connecting mechanism 20. In this embodiment, the number of each group of limiting mechanisms 40 is three, and the three limiting mechanisms 40 are distributed in a ring array. In other embodiments, the number of limiting mechanisms 40 can be two, four or more.

[0036] When installing the bracket, one of the support mechanisms 10 is first placed on top of the mounting base 30 and bolted together. The other support mechanism 10 and the connecting mechanism 20 are then connected in sequence from bottom to top. During the connection process, the position limiting mechanism 40 can be used to prevent the placed support mechanism 10 or connecting mechanism 20 from shifting due to the influence of the crane or wind.

[0037] The support mechanism 10 includes a support assembly 11, an adjustment assembly 12, a flange 13, a plug assembly 14, and a sliding assembly 15. The adjustment assembly 12 is positioned above the interior of the support assembly 11, the flange 13 is mounted outside the bottom end of the support assembly 11, the plug assembly 14 is positioned outside the top end of the support assembly 11, and the sliding assembly 15 is positioned below the interior of the support assembly 11. Multiple limiting mechanisms 40 are arranged in a circular array along the axis of the support assembly 11 and outside the support assembly 11. The bottoms of the limiting mechanisms 40 extend through the flange 13 and beyond.

[0038] When installing the support mechanism 10, first place the support assembly 11 on top of the mounting base 30, aligning the flange holes on the flange plate 13 with the mounting holes on the mounting base 30. The retaining mechanism 40 on the support assembly 11 then inserts into the mounting base 30 to prevent the support assembly 11 from shifting. To join two support mechanisms 10, a crane is used to hoist the other support mechanism 10 above the one connected to the mounting base 30. The sliding assembly 15 in the other support mechanism 10 now fits over the outside of the adjustment assembly 12.

[0039] As the other support mechanism 10 continues to move downward, when the two support mechanisms 10 are not completely aligned, the adjustment component 12 can drive the sliding component 15 to rotate, thereby driving the support component 11 in the other support mechanism 10 to rotate, so as to adjust the position of the flange 13 in the other support mechanism 10, so that the flange 13 in the other support mechanism 10 automatically aligns with the plug-in component 14 in the lower support mechanism 10. This eliminates the need for workers to manually adjust the position of the support mechanisms 10, facilitates the rapid splicing of the two support mechanisms 10, and reduces the risk of workers operating at height.

[0040] The support assembly 11 includes a steel pipe 111, a connecting plate 112, and a diagonal brace 113. The limiting mechanism 40 on the support mechanism 10 is installed on the outside of the steel pipe 111. There are two groups of connecting plates 112, and the two groups of connecting plates 112 are distributed vertically on the outside of the steel pipe 111. Each group of connecting plates 112 has multiple connecting plates 112, and the multiple connecting plates 112 are distributed in a circular array centered on the axis of the steel pipe 111. The flange 13 is installed on the outside of the bottom end of the steel pipe 111, and the plug-in assembly 14 is installed on the outside of the top end of the steel pipe 111. There are two groups of diagonal braces 113, and the two groups of diagonal braces 113 are installed at both ends of the steel pipe 111 and connected to the flange 13 and the plug-in assembly 14 respectively.

[0041] The adjustment assembly 12 includes a mounting bracket 121, a fixed column 122, a spiral groove 123, a slide 124, and a positioning column 125. The mounting bracket 121 is mounted above the inner circumferential wall of the steel pipe 111, and the bottom end of the fixed column 122 is mounted on the top of the mounting bracket 121. There are four spiral grooves 123 and four slide 124, respectively. These four spiral grooves 123 and four slide 124 are arranged in a circular array on the outside of the fixed column 122, centered around the axis of the fixed column 122. The slide 124 is connected to the spiral groove 123, with the bottom end of the slide 124 co-located with the end of the spiral groove 123, and the top end of the slide 124 is adjacent to the beginning of the spiral groove 123. The bottom end of the positioning column 125 is mounted on the top of the fixed column 122. The top end of the positioning column 125 is conical and extends through the top of the steel pipe 111 and out of the steel pipe 111.

[0042] When the two support mechanisms 10 are joined, the upper support mechanism 10 is moved downward, and the sliding assembly 15 inside it is sheathed on the outside of the positioning column 125, facilitating the positioning of the upper support mechanism 10 and allowing it to fall vertically. The upper support mechanism 10 is then moved further downward, and the sliding assembly 15 inside the support mechanism 10 is moved onto the fixed column 122, where it can be inserted into the spiral groove 123 or the sliding groove 124 on the fixed column 122.

[0043] When the sliding assembly 15 is inserted into the spiral groove 123, as the support mechanism 10 continues to move downward, the spiral groove 123 can drive the entire support mechanism 10 to rotate through the sliding assembly 15, thereby adjusting the position of the flange 13 on the upper support mechanism 10. As the support mechanism 10 rotates, the sliding assembly 15 can enter the chute 124 along the trajectory of the spiral groove 123. When the sliding assembly 15 enters the chute 124, the upper support mechanism 10 moves vertically downward until it contacts the lower support mechanism 10. At this time, the flange 13 on the upper support mechanism 10 aligns with the plug assembly 14 on the lower support mechanism 10.

[0044] When the sliding component 15 is directly inserted into the slide groove 124, the upper support mechanism 10 moves vertically downward along the trajectory of the slide groove 124 and contacts the lower support mechanism 10. At this time, the flange 13 on the upper support mechanism 10 corresponds to the plug-in component 14 on the lower support mechanism 10 to achieve the effect of automatic alignment. There is no need for the staff to manually adjust the support mechanism 10, thereby saving splicing time, reducing the time for the staff to work at height, and reducing construction risks.

[0045] The mounting base 30 has the same structure as the plug-in assembly 14. In other embodiments, the adjustment assembly 12 can be installed on the mounting base 30, thereby further improving the installation efficiency of the steel pipe 111. The plug-in assembly 14 includes a flange 141 and a plurality of slots 142. The flange 141 is installed on the outside of the top end of the steel pipe 111, and the plurality of slots 142 are arranged in a circular array at the top end of the flange 141 with the axis of the flange 141 as the center. The number of slots 142 is equal to the number of each set of limiting mechanisms 40, and the bottom of the limiting mechanism 40 can be inserted into the slots 142. Limiting grooves 143 are provided on both sides of the inner wall of the slot 142.

[0046] When the limiting mechanism 40 is inserted into the slot 142 , the limiting mechanism 40 can extend into the limiting groove 143 to prevent the placed supporting mechanism 10 or connecting mechanism 20 from being offset by the crane or wind, thereby avoiding affecting subsequent installation work.

[0047] Sliding assembly 15 includes a mounting ring 151, a spring 153, and a stopper 154. Mounting ring 151 is mounted below the inner wall of steel pipe 111. A mounting groove 152 is defined within mounting ring 151. One end of spring 153 is mounted on the inner wall of mounting groove 152, while the other end of spring 153 is mounted on one end of stopper 154. The other end of stopper 154 extends through mounting groove 152 and into the interior of mounting ring 151.

[0048] When the mounting ring 151 is placed on the outside of the positioning post 125, the steel pipe 111 drives the limiting post 154 to contact the outside of the positioning post 125. As the steel pipe 111 continues to move downward, the positioning post 125 can press the limiting post 154 into the installation groove 152 and contact the inside of the mounting ring 151. At this time, the positioning post 125 and the mounting ring 151 cooperate to position the steel pipe 111 and prevent it from tilting. After the mounting ring 151 separates from the positioning post 125, it moves onto the fixed post 122. At this time, the positioning post 125 can be inserted into the spiral groove 123 or the sliding groove 124 of the fixed post 122.

[0049] The connecting mechanism 20 includes a steel pipe 21, a flange 3 22, a top plate 23, a sliding assembly 24, a connecting plate 25 and a diagonal brace 26. The limiting mechanism 40 on the connecting mechanism 20 is installed on the outside of the steel pipe 21. The limiting mechanism 40 on the connecting mechanism 20 passes through the flange 3 22 and extends to the outside of the flange 3 22. The flange 3 22 is installed on the outside of the bottom end of the steel pipe 21, and the top plate 23 is installed on the top of the steel pipe 21. The top of the top plate 23 is used to place the unloading block. The sliding assembly 24 is installed at the lower inside of the steel pipe 21. The sliding assembly 24 has the same structure as the sliding assembly 15. There are multiple connecting plates 25. Multiple connecting plates 25 are installed in a circular array in the middle of the outer side of the steel pipe 21 with the axis of the steel pipe 21 as the center. There are two groups of diagonal braces 26, and each group of diagonal braces 26 has multiple numbers. The two groups of diagonal braces 26 are respectively installed on the outside of the top end and the outside of the bottom end of the steel pipe 21, and the two groups of diagonal braces 26 are respectively fixed to the flange 3 22 and the top plate 23.

[0050] When splicing steel pipe 111 and steel pipe 21, steel pipe 21 is hoisted above steel pipe 111 and lowered toward steel pipe 111. Simultaneously, sliding assembly 24 within the assembly is positioned over positioning column 125 to position steel pipe 21. As steel pipe 21 continues to move downward, the spiral groove 123 and sliding groove 124 on fixing column 122 automatically align the flange holes of flange 3 22 on steel pipe 21 with the flange holes of flange 2 141 on steel pipe 111.

[0051] The limiting mechanism 40 includes a lifting lug 41, a lifting assembly 42, a hinge assembly 43, and a limiting assembly 44. The lifting lug 41 of the limiting mechanism 40 on the first steel pipe 111 is mounted outside the top end of the first steel pipe 111. The lifting lug 41 of the limiting mechanism 40 on the second steel pipe 21 is mounted outside the top end of the second steel pipe 21. The lifting assembly 42 is slidably connected to the inside of the lifting lug 41. The top end of the hinge assembly 43 is located at the bottom of the lifting assembly 42, and the bottom end of the hinge assembly 43 is located inside the limiting assembly 44.

[0052] Lifting assembly 42 includes a movable plate 421, a wedge 424, a protrusion 425, and a clamp. Movable plate 421 is slidably connected to the interior of lifting lug 41. A groove 422 for the lifting rope is defined on one side of the bottom of movable plate 421. A connecting groove 423 is defined within movable plate 421, communicating with groove 422. Wedge 424 is slidably connected to the interior of connecting groove 423. Protrusion 425 is mounted on top of wedge 424. The top of protrusion 425 extends through movable plate 421 and outward.

[0053] The clamping member includes a second wedge 426, a fixing rod 427, a second spring 428, and a tooth plate 429. The second wedge 426 is adapted to fit within the first wedge 424 and is slidably connected to one side of the inner bottom wall of the connecting groove 423. The fixing rod 427 is mounted on one side of the second wedge 426, with one end of the fixing rod 427 able to penetrate the connecting groove 423 and enter the groove 422. The second spring 428 is sleeved around the outside of the fixing rod 427, with both ends of the spring 428 respectively mounted between the inner wall of the connecting groove 423 and the second wedge 426, thereby resetting the second wedge 426. The tooth plate 429 is mounted on one end of the fixing rod 427, and a groove is defined on one side of the inner wall of the groove 422 to accommodate the tooth plate 429.

[0054] When lifting steel pipe 111 or steel pipe 21, the lifting rope is placed in the groove 422 of the movable plate 421. At this time, the lifting rope is pulled upward to drive the movable plate 421 to move upward and contact the inner wall of the lifting ear 41. During the upward movement of the movable plate 421, the protrusion 425 is gradually pressed into the movable plate 421. At this time, the protrusion 425 pushes the wedge block 426 to move horizontally through the wedge block 1 424. The wedge block 426 drives the tooth plate 429 toward the lifting rope through the fixed rod 427, thereby clamping the lifting rope in the groove 422, preventing the lifting rope from slipping when lifting steel pipe 111 or steel pipe 21, thereby improving the stability during lifting.

[0055] The hinge assembly 43 includes a connecting rod 431, a mounting plate 432, a hinge seat 433, an articulated arm 434, and a third spring 435. There are two connecting rods 431, two articulated seats 433, and two articulated arms 434. The top ends of the two connecting rods 431 are mounted on the bottom of the movable plate 421. The mounting plate 432 is located inside the retaining assembly 44. The bottom ends of the connecting rods 431 are mounted on the top of the mounting plate 432. The bottom end of the third spring 435 is mounted on the top of the mounting plate 432 and is located between the two connecting rods 431. The two articulated seats 433 are mounted on either side of the bottom of the mounting plate 432 and are hinged to the two articulated arms 434.

[0056] When the movable plate 421 moves upward, the movable plate 421 drives the mounting plate 432 upward through the connecting rod 431. At this time, the mounting plate 432 can drive the hinge arm 434 upward through the hinge seat 433. At this time, the spring three 435 is compressed and stored.

[0057] The limiting assembly 44 includes a plug plate 441, a slide bar 442, a slide bar 443, and a limiting block 444. Both flange 13 and flange 3 22 are provided with slots for the bottom end of the plug plate 441 to pass through. The plug plate 441 in the limiting mechanism 40 on steel pipe 111 is fixed to flange 13, and the plug plate 441 in the limiting mechanism 40 on steel pipe 21 is fixed to flange 3 22. The slot 142 is adapted to the plug plate 441. The mounting plate 432 is located above the interior of the plug plate 441, and the top end of the spring 3 435 is mounted above the inner wall of the plug plate 441. There are two slide bars 442, which are arranged vertically within the interior of the plug plate 441 and fixed to its inner wall. There are two slide bars 443 and two limit blocks 444, each mounted on the bottom of one side of each slide bar 443. Slots are provided on the bottom of both sides of the insert plate 441 for the limit blocks 444 to extend through, and the limit blocks 444 fit into the limit slots 143. Both slide bars 443 are slidably connected to the slide bar 442, and the top ends of the slide bars 443 are hinged to the bottom ends of the hinged arms 434.

[0058] When the movable plate 421 moves upward, the movable plate 421 drives the hinged arm 434 to move upward through the mounting plate 432 on the connecting rod 431 . At this time, the hinged arm 434 drives the two slide bars 443 to approach each other so that the limit block 444 enters the plugging plate 441 .

[0059] When two steel pipes 111 are spliced ​​together or steel pipe 111 and steel pipe 2 are spliced ​​together, the insert plate 441 is gradually inserted into the slot 142 of the flange 2 141. When the insert plate 441 contacts the inner bottom wall of the slot 142, the lifting rope releases the pull on the movable plate 421. At this time, under the action of the reset force of the spring 3 435, the mounting plate 432 can be driven to reset, thereby driving the two slide bars 443 to reset, so that the limit block 444 is inserted into the limit groove 143 to prevent the steel pipe 111 or the steel pipe 2 21 from shaking or deflecting due to the influence of the crane or wind.

[0060] Working principle: First, place a steel pipe 111 on the mounting seat 30, so that the flange hole of the flange plate 13 on the steel pipe 111 corresponds to the mounting hole on the mounting seat 30. At this time, use bolts to match the flange plate 13 with the mounting seat 30 to fix the steel pipe 111 on the concrete base, and then start splicing the two steel pipes 111.

[0061] When splicing two steel pipes 111, the lifting rope is placed in the groove 422 of the movable plate 421. At this time, the lifting rope is pulled upward to drive the movable plate 421 upward and contact the inner wall of the lifting ear 41. As the movable plate 421 moves upward, the protrusion 425 is gradually pressed into the movable plate 421. At this time, the protrusion 425 pushes the wedge block 426 to move horizontally through the wedge block 1 424. The wedge block 426 drives the tooth plate 429 toward the lifting rope through the fixed rod 427, clamping the lifting rope in the groove 422. This prevents the lifting rope from slipping when lifting steel pipe 111 or steel pipe 21, thereby improving the stability during lifting.

[0062] When the hoisted steel pipe 111 is moved above the fixed steel pipe 111, the crane drives the hoisted steel pipe 111 downward, causing the mounting ring 151 to fit over the outer side of the positioning post 125. At this point, driven by the steel pipe 111, the limiting post 154 contacts the outer side of the positioning post 125. As the steel pipe 111 continues to move downward, the positioning post 125 presses the limiting post 154 into the mounting groove 152, contacting the inner side of the mounting ring 151. This position fixes the steel pipe 111 and prevents it from tilting. The mounting ring 151 separates from the positioning post 125 and moves over to the fixed post 122. At this point, the positioning post 125 can be inserted into the spiral groove 123 or the sliding groove 124 of the fixed post 122.

[0063] When fixing column 122 is inserted into spiral groove 123, as steel pipe 111 continues to move downward, spiral groove 123 causes fixing column 122 to rotate the entire steel pipe 111, thereby adjusting the position of flange 13 on the upper steel pipe 111. As steel pipe 111 rotates, fixing column 122 can follow the trajectory of spiral groove 123 and enter chute 124. When fixing column 122 enters chute 124, the hoisted steel pipe 111 moves vertically downward until it contacts the fixed steel pipe 111. At this point, flange 13 on the hoisted steel pipe 111 aligns with flange 2 141 on the fixed steel pipe 111.

[0064] When the fixing column 122 is directly inserted into the chute 124, the hoisted steel pipe 111 moves vertically downward along the track of the chute 124 and contacts the fixed steel pipe 111. At this time, the flange 13 on the hoisted steel pipe 111 aligns with the flange 2 141 on the fixed steel pipe 111, achieving an automatic alignment effect, eliminating the need for manual adjustment of the steel pipe 111, thus saving splicing time.

[0065] During the splicing process of the two steel pipes 111, the insert plate 441 is gradually inserted into the slot 142 of the second flange 141. When the insert plate 441 contacts the inner bottom wall of the slot 142, the lifting rope releases the pull on the movable plate 421. At this time, the restoring force of the third spring 435 can drive the mounting plate 432 back to its original position, thereby driving the two slide bars 443 back to their original position, allowing the stop block 444 to insert into the stop slot 143, thus preventing the first steel pipe 111 or the second steel pipe 21 from shaking or deflecting due to the influence of the crane.

[0066] The splicing principle of steel pipe 111 and steel pipe 21 is the same as the splicing principle of two steel pipes 111, which will not be repeated here.

A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
