Description

Technical Field

[0001] The present invention relates to the technical field of construction machinery, in particular to a large-scale steel column operation platform. Background Art

[0002] In the field of large-scale steel structure building construction, the single-column surrounding steel column operation platform is the core temporary tooling equipment for the high-altitude assembly construction of steel columns, and is widely used in steel column docking operations for projects such as super high-rise buildings, large industrial workshops, stadiums and gymnasiums, and steel structure towers. This type of operation platform is mainly clamped and fixed on the outer wall of the formed steel column by relying on a hoop structure, takes a single large steel column as the force-bearing attachment basis, extends outward to build a single-layer surrounding operation table surface, and is equipped with safety structures such as guard rails and anti-slip pedals, so as to provide a high-altitude operation space for construction personnel. It is mainly used in construction procedures such as steel column docking welding, final tightening of high-strength bolts, non-destructive testing of welds, component installation, and anti-corrosion and fire-proof coating. Compared with traditional floor-standing scaffolding and cantilever scaffolding, the single-column steel column operation platform has the advantages of convenient disassembly and assembly, light self-weight, recyclable turnover, no occupation of ground construction space, and adaptability to high-altitude segmented construction, which can effectively improve the efficiency of steel structure construction and reduce the cost of temporary frame erection. It has now become the mainstream operation equipment for high-altitude construction of large steel columns at the present stage, with extremely wide application scenarios;

[0003] However, we found in the actual use process that the hoops matched with the conventional steel column operation platforms on the market at present are all of fixed structures, and the inner clamping diameter of the hoop cannot be adjusted after being machined and formed. The outer diameters of large steel columns on the construction site are uneven, and even for steel columns of the same cross-section type, there are obvious differences in actual outer diameter parameters. During the construction process, the inner diameter of the hoop must precisely correspond to the outer diameter of the steel column to closely fit the surface of the column body and ensure the stable installation of the operation platform by means of clamping force. Once the size of the hoop does not match the steel column, problems such as excessive fitting gaps and loose clamping will occur, failing to meet the safety standards for high-altitude construction. In this case, the hoop component with the corresponding inner diameter can only be disassembled and replaced. The fixed-size hoop has poor versatility, and the construction site needs to store accessories of various inner diameter models, resulting in low component recycling efficiency. Frequent disassembly, assembly and replacement of hoops not only increases construction consumables and labor costs, but also prolongs the on-site operation time, and the overall construction efficiency is significantly restricted. For this reason, we propose a large-scale steel column operation platform. Summary of the Invention

[0004] One technical problem to be solved by the present application is: how to realize adaptive clamping of the hoop structure when facing steel columns with different outer diameters, so as to adapt to steel columns with various outer diameters without replacing the hoop components, improve the versatility of the hoop and the on-site adaptation efficiency, and at the same time ensure the structural stability and installation safety under high-altitude operation conditions.

[0015] In some embodiments, the first clamping assembly includes an assembly disposed on the first hoop, which uses the assembly to restrict one end of each of the two second hoops within adjustment slots opened at both ends of the first hoop. The first hoop is provided with pushers at both ends, which apply pressure to one end of the two second hoops and the two second trapezoidal plates, driving the two second hoops and the two second trapezoidal plates to slide along the length of the adjustment slot toward the steel column body.

[0016] In some embodiments, the assembly includes assembly blocks disposed at both ends of the first hoop, each assembly block having an assembly bolt at both ends, the two assembly blocks being threadedly connected to both ends of the first hoop via corresponding assembly bolts, and the two assembly blocks being located at opposite ends of the two adjustment slots.

[0019] In some embodiments, the second clamping assembly includes a synchronous retraction member disposed on the second hoop, which drives one end of the two first hoops and the two first trapezoidal plates to slide synchronously on the outer side of the corresponding second hoop. An adjustment member is disposed on the outer side of the second hoop, which is used to adjust the distance between the first trapezoidal plate and the first hoop, thereby driving multiple extrusion plates on the first trapezoidal plate to extrude pressure on the outer wall of the first hoop.

[0020] In some embodiments, the synchronous retraction component includes a synchronous shaft rotatably disposed within the second hoop plate. Synchronous screws are provided at both ends of the synchronous shaft, with the two synchronous screws rotating in opposite directions.

Two mounting grooves are opened on opposite sides of the two second retracting plates. Adjusting blocks are slidably disposed in the four mounting grooves. The four adjusting blocks are respectively rotatably disposed at the ends of the four adjusting screws near the steel column body. Adjusting heads are disposed at the ends of the four adjusting screws away from the four mounting grooves.

[0022] The present invention has at least the following beneficial effects:

[0023] 1. Relying on the sliding fit structure of two first hoop plates, two second hoop plates, and four adjustment slots, combined with the assembly and pushing parts of the first clamping component and the synchronous retraction part of the second clamping component, flexible adaptation to square steel column bodies of different sizes can be achieved. By disassembling and assembling the assembly blocks at both ends of the first hoop plate, the ends of the second hoop plate and the second trapezoidal plate can be slidably assembled into the adjustment slot. With the counter-rotating synchronous screw and retraction rod structure of the synchronous retraction part, the first hoop plate and the first trapezoidal plate can be driven to slide and adjust the distance synchronously. The entire adjustment structure does not require replacement of the adapting components and can flexibly adjust the encircling clamping range according to the size of the steel column on site. It effectively solves the problems of fixed size and poor adaptability of traditional working platforms, and greatly improves the equipment versatility and on-site installation and commissioning efficiency.

[0024] 2. The gradient clamping structure formed by the extrusion components of the stabilizing and anti-detachment assembly effectively improves the clamping stability and fitting accuracy of the hoop plates. Utilizing multiple sets of extrusion plates with gradually varying lengths on the first and second trapezoidal plates, combined with the guiding and limiting effects of triangular plates, guide grooves, and guide rods, a gradient clamping force is formed from the center to both sides. This can preferentially constrain the middle section of the first or second hoop plates, effectively suppressing problems such as central suspension, warping deformation, and poor fitting caused by excessive end force on the first and second hoop plates. At the same time, the differentiated graded extrusion mode completely avoids the defects of local stress concentration and uneven circumferential clamping force. Furthermore, the triangular plates can enhance the load-bearing capacity and torsional stiffness of the ear plates, and the guide rods ensure the precise sliding trajectory of the components, greatly improving the overall assembly accuracy and reliability for repeated use.

[0025] 3. The anti-fall device and the rubber plate in the installation groove form a dual safety protection system, which greatly improves the safety factor of high-altitude operations. The rubber plate in the installation groove of the first and second hoop plates can balance the clamping force through elastic deformation, avoiding the steel column body from being rigidly squeezed and scratched. At the same time, it absorbs the instantaneous impact load of construction, increases the friction of the contact surface, and strengthens the clamping firmness. If the clamping fails or the component loosens and gaps are generated, the anti-fall torsion spring can drive the anti-fall shaft and the arc plate to move, and drive the rubber anti-fall plug plate to self-lock into the gap along the bottom slope of the hoop plate, quickly filling the gap and forming support, effectively preventing the hoop plate from sliding axially. Through adaptive gap compensation and the inclined self-locking structure, the safety redundancy and structural stability of the equipment for high-altitude operations are comprehensively improved.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-12 The present invention provides a technical solution: a large steel column working platform, including a steel column body 1, a working platform body 15, and ear plates 2, and further including:

[0041] There are two first hoop plates 3, and the two first hoop plates 3 are respectively located on both sides of the steel column body 1;

[0042] There are two second hoop plates 4, and the two second hoop plates 4 are respectively located on the other two sides of the steel column body 1, alternating with the two first hoop plates 3, and distributed in a rectangular array.

[0043] The adjustment groove 5 has four openings, and the four adjustment grooves 5 are respectively opened at both ends of the two first hoop plates 3. The two second hoop plates 4 are respectively slidably set at both ends of the two first hoop plates 3 through the corresponding adjustment grooves 5.

[0044] The stabilizing and anti-detachment component 6 is set on the outside of the two first hoop plates 3 and the two second hoop plates 4. It is used to drive the two first hoop plates 3 and the two second hoop plates 4 to fit against the steel column body 1, while limiting the longitudinal displacement of the two first hoop plates 3 and the two second hoop plates 4.

[0045] There are two first clamping components 7, and the two first clamping components 7 are respectively located on the outside of the two first hoop plates 3. The two first clamping components 7 drive the two ends of the two second hoop plates 4 to slide in the corresponding adjustment grooves 5, thereby driving the two second hoop plates 4 to move closer to the center of the steel column body 1 and clamp the steel column body 1.

[0046] There are two second clamping components 8, and the two second clamping components 8 are respectively located on the outside of the two second hoop plates 4. The two second clamping components 8 drive the two first hoop plates 3 to slide through the corresponding adjustment grooves 5 at both ends of the two second hoop plates 4, thereby driving the two first hoop plates 3 to move closer to the center of the steel column body 1 and cooperate with the two second hoop plates 4 to form a four-way clamping of the steel column body 1.

[0047] The stabilizing and anti-detachment component 6 includes an extrusion member 9 disposed on the outside of the two first hoop plates 3 and the two second hoop plates 4. The extrusion member 9 is used to drive the two first hoop plates 3 and the two second hoop plates 4 to tightly adhere to the surface of the steel column body 1 on opposite sides. The bottom of the two first hoop plates 3 and the two second hoop plates 4 is provided with an anti-fall member 10, which is used to constrain the longitudinal displacement of the two first hoop plates 3 and the two second hoop plates 4.

[0048] The extrusion component 9 includes multiple triangular plates 91 respectively disposed on the opposite sides of the two first hoop plates 3 and the two second hoop plates 4. Four ear plates 2 are disposed on the top of the corresponding multiple triangular plates 91, with their opposite ends disposed on the outer sides of the two first hoop plates 3 and the two second hoop plates 4. A first trapezoidal plate 92 is disposed on the opposite side of each of the two first hoop plates 3, and a second trapezoidal plate 93 is disposed on the opposite side of each of the two second hoop plates 4. The two first trapezoidal plates 92 are slidably disposed at both ends of the two second hoop plates 4. Auxiliary grooves 94 are provided at both ends of each of the two second trapezoidal plates 93. Within the adjustment groove 5, multiple extrusion plates 95 are provided on the side of the two first trapezoidal plates 92 and the two second trapezoidal plates 93 near the steel column body 1. The multiple extrusion plates 95 and multiple triangular plates 91 are arranged alternately. Among the multiple extrusion plates 95, the multiple extrusion plates 95 located on the same first trapezoidal plate 92 or second trapezoidal plate 93 form a group, which is divided into four groups. In each group of extrusion plates 95, the extrusion plate 95 located in the center is the longest and gradually decreases in length towards both sides. Guide grooves 96 are provided on the multiple triangular plates 91 and the four groups of extrusion plates 95. The multiple guide grooves 96 are divided into four groups, and a guide rod 97 is slidably provided in each group of guide grooves 96.

[0049] When the two ends of the first trapezoidal plate 92 are compressed, the two ends of the first trapezoidal plate 92 will slide onto one end of each of the two second hoop plates 4, thereby causing the first trapezoidal plate 92 to translate along the ends of the second hoop plates 4 toward the steel column body 1. At the same time, the multiple compression plates 95 set on the first trapezoidal plate 92 will be pushed by the first trapezoidal plate 92 and gradually move closer to and adhere to the outside of the first hoop plate 3, so that the multiple compression plates 95 on the first trapezoidal plate 92 apply progressive radial pressure to the side of the first hoop plate 3 away from the steel column body 1. In this process, the compression plate 95 set on the first trapezoidal plate 92 and located in the middle section will first contact and press the first hoop plate 3. As the compression of the two ends of the first trapezoidal plate 92 continues, the first trapezoidal plate 92 will produce slight deformation, thereby causing the remaining compression plates to... Plates 95 sequentially follow and contact and press, forming a gradient clamping force that gradually increases from the center to both sides until all extrusion plates 95 are tightly attached to the outer side of the first hoop 3, thus completing the clamping of the first hoop 3. Similarly, when extrusion is applied to both ends of the second trapezoidal plate 93, its two ends slide along the adjustment grooves 5 opened at the ends of the two first hoop 3, driving the second trapezoidal plate 93 to translate towards the steel column body 1. This causes the multiple extrusion plates 95 set on the second trapezoidal plate 93 to gradually attach and press against the outer side of the second hoop 4, forming a gradient clamping force that gradually increases from the center to both sides. Finally, the first hoop 3 and the second hoop 4 are clamped together, thus ensuring that the first hoop 3 and the second hoop 4 form a stable, uniform and adaptive circumferential clamping force in the circumference of the steel column body 1.

[0050] Through the gradient distribution design of four sets of compression plates 95, priority and stronger radial constraints are applied to the middle section of the two first hoop plates 3 and the two second hoop plates 4. This effectively suppresses structural instability phenomena such as poor adhesion to the side wall of the steel column body 1, mid-section suspension, or warping deformation caused by excessive end forces on the two first hoop plates 3 and the two second hoop plates 4. As a result, the two first hoop plates 3 and the two second hoop plates 4 can tightly adhere to the circumferential surface of the steel column body 1, avoiding problems such as local stress concentration or uneven clamping force. The multiple triangular plates 91 respectively set on the two first hoop plates 3 and the two second hoop plates 4 can provide stable support for the ear plate 2, thereby enhancing the load-bearing capacity of the ear plate 2. In addition to torsional stiffness, to prevent the ear plate 2 from bending or loosening under construction loads, the four guide rods 97 can limit and guide the positions of the two first trapezoidal plates 92 and the two second trapezoidal plates 93 respectively through the guide grooves 96 opened on the multiple triangular plates 91 and the multiple extrusion plates 95, so that the four sets of extrusion plates 95 can slide smoothly along the preset trajectory, and apply the extrusion force directly and accurately to the outside of the two first hoop plates 3 and the two second hoop plates 4. At the same time, it can also ensure that the first trapezoidal plate 92 or the second trapezoidal plate 93 will not detach from the corresponding first hoop plate 3 or the second hoop plate 4 during disassembly, effectively improving the assembly accuracy and reusability of the overall structure.

[0051] The fall arrestor 10 includes fall arrestor shafts 101 rotatably disposed at the bottom of the two first hoop plates 3 and the two second hoop plates 4 respectively. Fall arrestor torsion springs 102 are disposed on the outer side of each of the four fall arrestor shafts 101. The other ends of the four fall arrestor torsion springs 102 are disposed at the bottom of the corresponding first hoop plates 3 and the second hoop plates 4 respectively. Arc plates 103 are disposed at both ends of the four fall arrestor shafts 101. Fall arrestor plugs 104 are disposed below the two first hoop plates 3 and the two second hoop plates 4 respectively. The top of the four fall arrestor plugs 104 is inclined on the side away from the steel column body 1. The four fall arrestor plugs 104 are rotatably disposed at the bottom of the corresponding two arc plates 103 respectively through a rotating shaft. The bottom of the two first hoop plates 3 and the two second hoop plates 4 is inclined on the side near the steel column body 1. Installation grooves 105 are opened on the side of the two first hoop plates 3 and the two second hoop plates 4 near the steel column body 1. Rubber plates 106 are disposed in the multiple installation grooves 105 and the multiple rubber plates 106 are in contact with the outer side of the steel column body 1.

[0052] When the first hoop 3 and the second hoop 4 are compressed and move towards the steel column body 1, the rubber plates 106 set in the multiple mounting grooves 105 simultaneously undergo elastic compression deformation. Their reaction force forms a dynamic balance with the clamping force applied by the hoop, thereby ensuring sufficient clamping force while significantly reducing the risk of indentations or scratches on the surface of the steel column body 1 caused by rigid contact. The damping characteristics of the rubber plates 106 effectively absorb the instantaneous impact load during construction and increase the friction between the first hoop 3 and the second hoop 4 and the steel column body 1, thereby ensuring that the two first hoop 3 and the two second hoop 4 can be firmly and stably clamped to the circumferential surface of the steel column body 1. If an accidental instability or loosening occurs, such as the rubber plates 106 failing due to aging or a sudden drop in clamping force, causing the two first hoop 3 or the two second hoop 4 to fail to fit with the steel column body 1 and a gap to exist, the anti-fall shaft 101 rotates under the preload of the anti-fall torsion spring 102, driving the arc-shaped plates 103 at both ends to prevent falls. Shaft 101 rotates around its axis, causing the anti-fall plug 104, which is rotatably connected to the bottom of the arc-shaped plate 103 via the shaft, to slide upwards along the inclined surface at the bottom of the first hoop 3 or the second hoop 4. This causes the anti-fall plug 104 to become lodged between the outer side of the steel column body 1 and the bottom of the first hoop 3 or the second hoop 4. This allows the anti-fall plug 104 to quickly fill the gap between the first hoop 3 or the second hoop 4 and the steel column body 1 and form a support, effectively preventing the first hoop 3 or the second hoop 4 from sliding upwards along the steel column body 1. In case of accidental axial slippage, it should be noted that the anti-fall plug 104 is made of rubber. When it is inserted into the contact surface between the first hoop 3 or the second hoop 4 and the steel column body 1, its elastic deformation can further compensate for the small gap. In addition, the inclined surface at the top of the anti-fall plug 104 can form a self-locking fit with the inclined surface at the bottom of the first hoop 3 and the second hoop 4, making it easier for the anti-fall plug 104 to be inserted into the gap between the first hoop 3 or the second hoop 4 and the steel column body 1, thereby improving the reliability of the anti-fall response and the self-locking stability.

[0053] The first clamping assembly 7 includes an assembly 11 disposed on the first hoop 3. The assembly 11 is used to restrict one end of each of the two second hoops 4 into the adjustment grooves 5 opened at both ends of the first hoop 3. The first hoop 3 is provided with pushers 12 at both ends. The pushers 12 apply pressure to one end of the two second hoops 4 and the two second trapezoidal plates 93, driving the two second hoops 4 and the two second trapezoidal plates 93 to slide along the length of the adjustment grooves 5 toward the steel column body 1.

[0054] The assembly 11 includes assembly blocks 111 disposed at both ends of the first hoop 3. Both ends of the two assembly blocks 111 are provided with assembly bolts 112. The two assembly blocks 111 are threadedly connected to both ends of the first hoop 3 through corresponding assembly bolts 112. The two assembly blocks 111 are located at opposite ends of the two adjustment grooves 5.

[0055] When surrounding the steel column body 1 with the two first hoop plates 3 and the two second hoop plates 4, the two assembly blocks 111 at the same end of the two first hoop plates 3 must first be removed. By twisting the assembly bolts 112, the two assembly blocks 111 are separated from the corresponding ends of the first hoop plates 3. Then, the two ends of the second hoop plates 4 are inserted into the two adjusting slots 5 respectively. Next, the two ends of the corresponding second trapezoidal plates 93 are inserted into the adjusting slots 5 along with the ends of the second hoop plates 4. Finally, the assembly blocks 111 are reset and the assembly bolts 112 are tightened. At this time, the two ends of the two second hoop plates 4 and the two ends of the two second trapezoidal plates 93 are... The two first hoop plates 3 and the two first trapezoidal plates 92 are in a sliding state within the four adjustment slots 5, while the two ends of the first hoop plates 3 and the two ends of the second trapezoidal plates 93 slide on the two ends of the second hoop plates 4 and the two second trapezoidal plates 93, respectively. This forms a closed, adjustable rectangular enclosure between the two first hoop plates 3 and the two second hoop plates 4, allowing the two first hoop plates 3 and the two second hoop plates 4 to be suitable for square steel column bodies 1 of different sizes. This enables the two first hoop plates 3 and the two second hoop plates 4 to be flexibly adapted when facing square steel column bodies 1 of different sizes, significantly improving the versatility of the device and the efficiency of on-site installation.

[0056] The propulsion component 12 includes rotating rings 121 rotatably mounted on two assembly blocks 111. Each rotating ring 121 has a rotating block 122 at its opposite ends and a rotating sleeve 123 at its opposite ends. The two rotating sleeves 123 are rotatably mounted in their respective assembly blocks 111. Each rotating sleeve 123 has a threaded groove 124 on its outer side and a transmission plate 125 on its outer side. The two transmission plates 125 are threadedly connected to their respective rotating sleeves 123 through the two threaded grooves 124. The two transmission plates 125 are slidably mounted on the opposite sides of the two second trapezoidal plates 93 and are slidably mounted in their respective adjustment grooves 5.

[0057] Two rotating blocks 122 are each rotatably equipped with a push screw 126 at their axis. The two push screws 126 are threadedly connected to the adjacent rotating sleeves 123. Each of the two rotating blocks 122 has a sliding groove 127. The opposite ends of the two push screws 126 are each slidably equipped with a slider 128, and the two sliders 128 are respectively used in conjunction with the corresponding sliding grooves 127. The opposite ends of the two push screws 126 are each rotatably equipped with a push block 129, and the two push blocks 129 are respectively slidably equipped on the opposite sides of the two second hoop plates 4. The two push blocks 129 are respectively slidably equipped in the corresponding auxiliary grooves 94.

[0058] After the workers surround the steel column body 1 with the two first hoop plates 3 and the two second hoop plates 4, they can rotate the slider 128 synchronously or one by one. Before this, a wrench must be used to hold the rotating block 122 so that it does not rotate and the slider 128 is disengaged from the slide groove 127. Then, the slider 128 is rotated by the wrench. When the slider 128 rotates, it will drive the push screw 126 to rotate. The push screw 126 will then gradually advance axially toward the steel column body 1 within the rotating sleeve 123, thereby causing the push block 129 to engage with the second hoop plates 4. The ends are squeezed, which pushes the second hoop 4 to slide along the adjusting groove 5 toward the steel column body 1 until the two second hoop 4 are firmly clamped on the outside of the steel column body 1. Then the slider 128 is slid into the corresponding groove 127. After ensuring that the slider 128 is in the groove 127, the rotating block 122 is rotated by a wrench, which causes the rotating block 122 to drive the rotating sleeve 123 to rotate in the assembly block 111. At this time, since the slider 128 is in the groove 127, when the rotating sleeve 123 rotates, the push screw 126 follows the rotating sleeve 127. 23 rotate together, thus keeping the push screw 126 and the rotating sleeve 123 in a relatively stationary state. This ensures that while the push screw 126 rotates with the rotating sleeve 123, it no longer undergoes axial displacement, thereby keeping the second hoop 4 in its current position and preventing further displacement, thus locking and positioning the second hoop 4. During the rotation of the rotating sleeve 123, the threaded groove 124 on the outer side of the rotating sleeve 123 drives the transmission plate 125, which is threadedly connected to it, to slide synchronously along the adjusting groove 5. This allows the transmission plate 125 to move relative to the second trapezoidal plate 9. The ends of 3 are squeezed, which pushes the second trapezoidal plate 93 to slide synchronously along the adjusting groove 5 towards the steel column body 1 until the two second trapezoidal plates 93 drive the corresponding squeezing plates 95 to squeeze the corresponding second hoop 4, realizing multi-point coordinated squeezing of the second hoop 4. While ensuring the clamping stability of the second hoop 4, it can also avoid the middle section of the second hoop 4 from warping due to excessive force at both ends, thereby significantly improving the fit and clamping stiffness between the second hoop 4 and the steel column body 1, and effectively suppressing the elastic deformation and local buckling of the second hoop 4 during the clamping process.

[0059] The second clamping assembly 8 includes a synchronous retraction member 13 disposed on the second hoop plate 4. The synchronous retraction member 13 drives one end of the two first hoop plates 3 and the two first trapezoidal plates 92 to slide synchronously on the outer side of the corresponding second hoop plate 4. An adjustment member 14 is disposed on the outer side of the second hoop plate 4. The adjustment member 14 is used to adjust the distance between the first trapezoidal plate 92 and the first hoop plate 3, thereby driving multiple extrusion plates 95 on the first trapezoidal plate 92 to extrude on the outer wall of the first hoop plate 3.

[0060] The synchronous retraction component 13 includes a synchronous shaft 131 rotatably disposed within the second hoop plate 4. Both ends of the synchronous shaft 131 are provided with synchronous screws 132, and the two synchronous screws 132 rotate in opposite directions. Both opposite ends of the two synchronous screws 132 are provided with synchronous blocks 133. Both ends of the second hoop plate 4 are provided with synchronous grooves 134. The two synchronous screws 132 are respectively located at the axis of the corresponding synchronous grooves 134. Retraction rods 135 are slidably disposed within the two synchronous grooves 134, and the two retraction rods 135 are respectively threadedly connected to the corresponding synchronous screws 132. The outer sides of the two retraction rods 135 are provided with first retraction plates 136 that cooperate with the two first hoop plates 3. The outer sides of the two retraction rods 135 are provided with second retraction plates 137 that cooperate with the two first trapezoidal plates 92, and the two second retraction plates 137 are respectively located on the opposite sides of the two first retraction plates 136.

[0061] When the first clamping plate 3 needs to be clamped, the synchronizing block 133 is rotated by a wrench, causing the synchronizing block 133 to drive the corresponding synchronizing screw 132 to rotate. This causes the rotating synchronizing screw 132 to drive the synchronizing shaft 131 to rotate as well. Thus, under the action of the synchronizing shaft 131, the two synchronizing screws 132 rotate synchronously. Since the two synchronizing screws 132 rotate in opposite directions, the two rotating synchronizing screws 132 respectively drive the two retracting rods 135 to slide towards or away from each other along the synchronizing groove 134. This causes the first retracting plate 136 and the second retracting plate 136 on the outer side of the two retracting rods 135 to slide towards or away from each other. The advancing plate 137 pushes the corresponding first hoop plate 3 and first trapezoidal plate 92 respectively, so that the two first hoop plates 3 and the two first trapezoidal plates 92 move synchronously towards or away from each other along both ends of the second hoop plate 4 until the two first hoop plates 3 are in contact with the surface of the steel column body 1 on opposite sides. While the two first hoop plates 3 are moving towards or away from each other, the advancing block 129 and the transmission plate 125 slide on the outside of the corresponding second hoop plate 4 and second trapezoidal plate 93 respectively. This ensures that the two first hoop plates 3 will not generate much resistance when moving towards or away from each other, thus ensuring the smoothness of the movement of the first hoop plates 3.

[0062] The adjusting component 14 includes adjusting screws 141 respectively disposed at both ends of the two second retracting plates 137, and the four adjusting screws 141 are respectively threadedly connected to the corresponding second retracting plates 137. Two mounting grooves 142 are opened on opposite sides of the two second retracting plates 137. Adjusting blocks 143 are slidably disposed in the four mounting grooves 142, and the four adjusting blocks 143 are respectively rotatably disposed at the end of the four adjusting screws 141 near the steel column body 1. Adjusting heads 144 are provided at the end of the four adjusting screws 141 away from the four mounting grooves 142.

[0063] After the two first hoop plates 3 are pressed into contact with the surface of the steel column body 1, the adjusting head 144 can be rotated by wrench. When the adjusting head 144 rotates, it will drive the corresponding adjusting screw 141 to rotate inside the second retracting plate 137. When the adjusting screw 141 rotates, it will drive the corresponding adjusting block 143 to make a fine adjustment and pressing on the end of the first trapezoidal plate 92, so that the end of the second trapezoidal plate 93 moves toward the first hoop plate 3. This causes the first trapezoidal plate 92 to drive the corresponding pressing plate 95 to press toward the outer wall of the first hoop plate 3 until the pressing plate 95 on the first trapezoidal plate 92 is completely in close contact with the outer wall of the first hoop plate 3. This further tightens the clamping contact surface between the first hoop plate 3 and the steel column body 1, preventing the middle section of the first hoop plate 3 from arching due to excessive extrusion pressure, thereby significantly improving the clamping stability of the first hoop plate 3 on the steel column body 1.

[0064] Under the action of the adjustment groove 5, the distance between the two first hoop plates 3 and the two second hoop plates 4 can be adjusted according to the size of the steel column body 1 on site, so as to adapt to steel column bodies 1 of different sizes. In addition to the improvement of size adaptation, multiple extrusion plates 95 of different lengths can also achieve multi-point and graded extrusion of the outer walls of the first hoop plates 3 and the second hoop plates 4, thereby forming a differentiated clamping force distribution in different stress areas. In addition, the anti-fall plug plate 104, together with the inclined surface at the bottom of the first hoop plates 3 and the second hoop plates 4, provides anti-fall treatment for the first hoop plates 3 and the second hoop plates 4, effectively preventing the risk of falling due to accidental instability during high-altitude operations, and further enhancing the safety redundancy and structural reliability of high-altitude operations.
