Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a construction method for a main tower in the shape of a water drop curve by replacing a curve with a straight line. Background Art

[0002] A cable-stayed bridge is a bridge structure system that uses cables as the main load-bearing components and is composed of pressure-bearing towers, tensioned cables, and bending beams. As the most commonly used method in the construction of the main tower of a cable-stayed bridge, the hydraulic climbing formwork segmented casting method can accurately and effectively control the line shape of the main tower and ensure the construction quality. However, although the hydraulic climbing formwork segmented casting method has the characteristics of high precision, low cost, high efficiency, and low risk, the main tower construction process still has certain difficulties due to the complex structure of the water drop curve main tower, the difficulty in designing and manufacturing the hydraulic climbing formwork, the high difficulty of the segmented casting technology, and the high risk of safety management. Therefore, in order to improve the safety of the climbing formwork segmented casting, the present invention provides a water drop curve main tower construction method that uses straight lines instead of curves to meet the needs. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a construction method for a main tower in the shape of a teardrop curve using a straight line instead of a curve. By setting an anti-fall component, not only can the guide rail be prevented from falling during the climbing process, but also the firmness of the fit between the overall structure of the embedded system and the concrete can be improved, the stability of the wall-attached seat structure can be improved, and the guide rail can be avoided from shaking during the climbing process. The above setting can solve the problem of poor safety and easy falling of the guide rail during the current climbing formwork segmented casting process.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] Step 2, construction of the 3rd to 5th sections: After pouring to the 3rd section and the overall arrangement of the small face frame is completed, the hydraulic climbing formwork device is used for standard construction. After the 3rd section of the large face is constructed, the 4th section is constructed, and the hydraulic climbing formwork installation method of the small face is repeated. When the 5th section is constructed, the large face enters the standard construction section;

[0008] Step 3. Construction of the 6th to 18th segments: During the construction of the 4th, 9th, 11th, and 18th segments, due to the presence of thickened partition walls inside the tower, brackets and supporting formworks are installed at the lower part of the partition walls. Starting from the 9th segment, the two tower legs are closed to form one tower leg, and a closure load-bearing bracket is installed at the lower part of the 9th segment.

[0012] Optionally, a bending part is installed at the connection position between the expansion plate and the climbing cone. The bending part has an outwardly convex arc-shaped profile, one end of the expansion plate is fixed to the climbing cone, and the other end is an open structure.

[0013] Optionally, a plug board with an "L" - shaped profile is fixedly connected to one side of the first rotating plate close to the wall - attached seat. An insertion cylinder corresponding to the position of the plug board is fixedly connected to the outer wall of the wall - attached seat. A clamping board with a "V" - shaped profile is fixedly connected to the other side of the first rotating plate. A first rotating block is fixedly connected to the first rotating shaft. A first rotating groove adapted to the length of the first rotating block is formed at the top of the first rotating plate.

[0014] Optionally, one end of the second rotating plate is fixedly connected to a first inclined plate, which abuts against the clamping board. A second rotating block is fixedly connected to the middle position of the second rotating shaft.

[0016] Optionally, third rotating blocks are fixedly connected to the outer walls at both ends of the second rotating shaft.

[0017] Optionally, a limiting groove is formed at the top of the guide rail, and a locking plug is inserted into the limiting groove. A climbing formwork groove is formed on one side of the guide rail close to the reversing box.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above - mentioned solution, by setting the anti - falling component, not only can the phenomenon of the guide rail falling during the climbing process be prevented, but also the firmness of the overall structure of the embedded part system in cooperation with the concrete can be improved, the stability of the wall - attached seat structure can be enhanced, and the phenomenon of the guide rail shaking during the climbing process can be avoided. The anti - falling component can have a structural cooperation with the hanging seat, and the achieved cooperation effect enables mutual limitation between the hanging seat and the wall - attached seat, preventing the hanging seat from running off and being unstable when the guide rail is inserted into the hanging seat. The anti - falling component can also have a structural cooperation with the reversing box, and the achieved cooperation effect enables double anti - falling limit between the reversing box and the guide rail during the climbing process of the guide rail, improving the safety and climbing efficiency of the guide rail.

[0020] By setting the expansion plate and the inner pushing plate, when the operator screws the installation bolt into the climbing cone, the inner pushing plate is extruded by the installation bolt and moves towards the fixed end of the expansion plate. During the movement of the inner pushing plate, it will extrude the expansion plate. During the process of the inner pushing plate extruding the expansion plate, it will drive the expansion plate to expand and deform at the bending part. During the deformation process of the expansion plate, it will extrude the concrete on the outer wall of the climbing cone, thereby improving the firmness of the cooperation between the climbing cone and the concrete, preventing the concrete from cracking and affecting the stability of the climbing cone, and thus ensuring the stability after the wall attachment seat is installed at the end of the climbing cone, and improving the efficiency of the guide rail insertion and the firmness after the guide rail is inserted.

[0021] By setting the insertion plate and the insertion cylinder, after the insertion plate and the insertion cylinder are inserted together, the insertion plate cooperates with the insertion cylinder to limit the hanging seat, preventing the hanging seat from sliding and shifting. Such a setting ensures that when the guide rail climbs to the bottom of the hanging seat, it can be accurately inserted into the hanging seat, and the guide rail insertion will not fail due to position deviation, thereby affecting the climbing efficiency of the guide rail. Moreover, under the limiting action of the insertion plate and the insertion cylinder, the stability between the hanging seat and the wall attachment seat can be improved, and thus the firmness of the guide rail can be improved.

[0022] By setting the clamping plate and the first inclined plate, during the climbing process of the guide rail, the first inclined plate will automatically avoid under the guiding action of the clamping plate, ensuring that the guide rail can smoothly pass through the clamping plate. If the guide rail drops during the climbing process, at this time, the first inclined plate cooperates with the clamping plate to block and limit the dropping guide rail, thereby achieving the anti-drop effect and ensuring the safety of the guide rail climbing.

[0023] By setting the second inclined plate and the positioning plate, if the guide rail drops, the second inclined plate will abut against the top of the reversing box. Since the included angle between the positioning plate and the second inclined plate is ninety degrees, when the second inclined plate abuts against the reversing box, the positioning plate will abut against one side of the reversing box. At this time, the second inclined plate cooperates with the positioning plate to block and limit the guide rail, thereby preventing the guide rail from continuing to drop. Through the setting of the above structure, when the guide rail drops, the second inclined plate cooperates with the positioning plate to double-block and protect the guide rail, improving the safety of the guide rail climbing.

[0047] As Figures 1 to 5 shown, an embodiment of the present invention provides a construction method for the main tower with a water-drop curve shape substituting curves with straight lines, including the following steps:

[0048] Step 1: Construction of the 1st to 3rd segments: The formwork is supported by embedding support steel bars on a large surface to arrange the framework as a construction platform. The small surface circular arc segment is poured in the way of substituting curves with straight lines. The framework is installed on the small surface, and the hydraulic climbing formwork device is used to construct the small surface;

[0049] Step 2: Construction of the 3rd to 5th segments: When pouring to the 3rd segment, after the overall arrangement of the framework on the small surface is completed, the standard construction is carried out using the hydraulic climbing formwork device. After the 3rd segment of the large surface is constructed, the 4th segment is constructed. The installation method of the hydraulic climbing formwork on the small surface is repeated. When constructing to the 5th segment, the large surface enters the standard construction segment;

[0050] Step 3: Construction of the 6th to 18th segments: When constructing the 4th, 9th, 11th, and 18th segments, due to the partition wall with a thickened section inside the tower, brackets and supporting formwork are installed at the lower part of the partition wall. Starting from the 9th segment, the two tower legs are closed into one tower leg. A closing load-bearing bracket is installed at the lower part of the 9th segment. After the construction of the 18th segment is completed, the hydraulic climbing formwork device is removed;

[0051] The hydraulic climbing formwork device includes a formwork system, a framework system, a hydraulic climbing system, an electrical control system, and an embedded part system. Among them, the anti-falling climber in the hydraulic climbing system is installed on the concrete construction segment through the embedded part system. In this application, the working principle of the hydraulic climbing formwork device is disclosed as the prior art, so no further elaboration is made;

[0052] The anti-falling climbing device includes a guide rail 4 and a reversing box 6. The embedded part system includes climbing cones 3, wall-attached seats 1 and hanging seats 2. The wall-attached seat 1 is fixedly connected to one end of the climbing cone 3. The hanging seat 2 is hung on the outer wall of the wall-attached seat 1. One side of the guide rail 4 is slidably connected in the hanging seat 2, and the reversing box 6 is slidably connected to the other side of the guide rail 4;

[0053] The anti-falling component is used to prevent the guide rail 4 from falling during the climbing process. The anti-falling component is respectively connected to the climbing cone 3, the hanging seat 2 and the guide rail 4. A limiting groove 401 is opened at the top of the guide rail 4, and a locking plug 402 is inserted into the limiting groove 401. A climbing form groove 403 is opened on one side of the guide rail 4 close to the reversing box 6. During the climbing process of the guide rail 4, the reversing tongue inside the reversing box 6 expands and contracts in the climbing form groove 403, and the guide rail 4 is unidirectionally limited by means of the climbing form groove 403 and the reversing tongue. In this application, the working principle between the reversing tongue and the guide rail 4 is disclosed as prior art, so no more details will be given. When the guide rail 4 climbs to the position of the hanging seat 2, the locking plug 402 is inserted into the limiting groove 401 at the top of the guide rail 4 (as Figure 4 shown), and the guide rail 4 is fixed by means of the locking plug 402.

[0054] At present, during the climbing process of the guide rail 4, it is only limited unidirectionally by the reversing box 6. Since the reversing box 6 is arranged on one side of the guide rail 4, the other side of the guide rail 4 is in a suspended state, so there is a risk of falling. Moreover, before the guide rail 4 climbs, the hanging seat 2 that currently fixes the guide rail 4 needs to be removed, and the new hanging seat 2 is installed above the guide rail 4. During the climbing process of the guide rail 4, it needs to be reinserted into the new hanging seat 2. However, at present, the hanging seat 2 and the wall-attached seat 1 are simply fixed by hanging, with poor stability. During the process of inserting the guide rail 4 into the hanging seat 2, the insertion may fail easily due to inaccurate position or unstable structure of the hanging seat 2, affecting the construction efficiency and progress. In this application, the anti-falling component is arranged on the embedded part system and the guide rail 4, which can prevent the guide rail 4 from falling during the climbing process. The anti-falling component can also improve the firmness of the overall structure of the embedded part system and the concrete, improve the stability of the structure of the wall-attached seat 1, and avoid the phenomenon of shaking of the guide rail 4 during the climbing process. The anti-falling component can cooperate with the hanging seat 2 structurally, and the achieved effect makes the hanging seat 2 and the wall-attached seat 1 limit each other, preventing the hanging seat 2 from running off and being unstable when the guide rail 4 is inserted into the hanging seat 2. The anti-falling component can also cooperate with the reversing box 6 structurally, and the achieved effect makes the guide rail 4 and the reversing box 6 perform double anti-falling limit during the climbing process of the guide rail 4, improving the safety and climbing efficiency of the guide rail 4.

[0055] In this embodiment, as Figures 1 to 7As shown in the figure, one end of the climbing cone 3 is screwed with a high-strength screw rod 301. The end of the high-strength screw rod 301 away from the climbing cone 3 is screwed with an embedded plate. The other end of the climbing cone 3 is screwed with an installation bolt 305. The wall attachment base 1 and the climbing cone 3 are screwed and fixed through the installation bolt 305. An inner plate 201 is fixedly connected inside the hanging seat 2. An outer limiting plate 202 is fixedly connected to the side of the hanging seat 2 away from the wall attachment base 1. An inner limiting plate 203 is fixedly connected to the inner wall of the hanging seat 2 near the outer limiting plate 202. The anti-falling component is connected to the inner plate 201. At present, the embedded system mainly consists of a climbing cone 3, a high-strength screw rod 301, an embedded plate and an installation bolt 305. Among them, the wall attachment base 1 is screwed and fixed to one end of the climbing cone 3 by means of the installation bolt 305. The embedded component needs to be placed in advance in the concrete pouring layer. After the concrete is poured, the operator can realize the installation and fixation of the wall attachment base 1 by means of the fixation effect of the concrete on the embedded component; there is a gap between the inner limiting plate 203 and the outer limiting plate 202 of the hanging seat 2. The setting of this gap is to allow one side of the guide rail 4 to be inserted between the inner limiting plate 203 and the outer limiting plate 202, so that the hanging seat 2 can limit one side of the guide rail 4.

[0056] As an implementation manner in this embodiment, as Figures 1 to 7As shown, the anti-falling component includes an expansion plate 302 fixedly connected to the outer wall of the climbing cone 3. An inner pushing plate 304 is slidably connected inside the climbing cone 3. A bending part 303 is installed at the connection position between the expansion plate 302 and the climbing cone 3. The bending part 303 has an outwardly convex arc-shaped contour. One end of the expansion plate 302 is fixed to the climbing cone 3 and the other end is of an open structure. During the actual construction process, in order to facilitate the operator to remove the climbing cone 3 from the concrete, the climbing cone 3 is generally of a conical structure, and the end of the climbing cone 3 close to the wall attachment base 1 is larger in size. Such a structure makes it easy for cracks to appear at the position of the climbing cone 3 after the concrete solidifies, resulting in the wall attachment base 1 being prone to shaking after being installed on the climbing cone 3, thereby affecting the fixing effect of the wall attachment base 1 on the hanging seat 2 and the guide rail 4. On the one hand, it makes the hanging seat 2 shake unsteadily and affects the docking of the guide rail 4. On the other hand, it affects the stability of the guide rail 4 during use. In this application, by installing the expansion plate 302 and the inner pushing plate 304 on the climbing cone 3, when the operator screws the installation bolt 305 into the climbing cone 3, the end of the installation bolt 305 will squeeze the inner pushing plate 304. In the initial state, the inner pushing plate 304 is located at the open end of the expansion plate 302, and the outer wall of the inner pushing plate 304 abuts against the inner wall of the expansion plate 302. When the inner pushing plate 304 is squeezed by the installation bolt 305, it will move towards the fixed end of the expansion plate 302. Since the overall contour of the climbing cone 3 is conical, when the inner pushing plate 304 moves towards the fixed end of the expansion plate 302, it will squeeze the expansion plate 302. Since the bending part 303 is installed at the connection position between the expansion plate 302 and the climbing cone 3, and the bending part 303 has an outwardly convex arc-shaped contour, during the process of the inner pushing plate 304 squeezing the expansion plate 302, it will drive the expansion plate 302 to expand and deform at the position of the bending part 303. During the deformation process of the expansion plate 302, it will squeeze the concrete on the outer wall of the climbing cone 3, thereby improving the firmness of the cooperation between the climbing cone 3 and the concrete, preventing the concrete from cracking and affecting the stability of the climbing cone 3, and further ensuring the stability of the wall attachment base 1 after being installed at the end of the climbing cone 3, and improving the insertion efficiency of the guide rail 4 and the firmness after the guide rail 4 is inserted.

[0057] In this embodiment, as Figures 7 to 11As shown, the anti-falling component further includes a first rotating shaft 204 fixedly connected to the inner plate 201. A first rotating plate 205 is rotatably connected to the first rotating shaft 204. On the side of the first rotating plate 205 close to the wall-attaching base 1, a plug plate 207 with an "L" - shaped profile is fixedly connected. On the outer wall of the wall-attaching base 1, a plug cylinder 101 corresponding to the position of the plug plate 207 is fixedly connected. On the other side of the first rotating plate 205, a clamping plate 206 with a "V" - shaped profile is fixedly connected. A first rotating block 209 is fixedly connected to the first rotating shaft 204. A first rotating groove 208 adapted to the length of the first rotating block 209 is formed at the top of the first rotating plate 205. A torsion spring is installed between the first rotating shaft 204 and the first rotating plate 205. The first rotating shaft 204 is installed at the middle position of the inner plate 201. The first rotating block 209 can rotate in the first rotating groove 208. Since the cross-sectional profile of the first rotating groove 208 is fan-shaped, the first rotating groove 208 can limit the first rotating block 209, so that the first rotating block 209 can only rotate within the profile of the first rotating groove 208. Such a setting makes the first rotating plate 205 can only rotate within the range of the fan-shaped cross-sectional profile of the first rotating groove 208. A torsion spring is installed between the first rotating shaft 204 and the first rotating plate 205. Here, the installation method and working principle of the torsion spring between the first rotating shaft 204 and the second rotating plate 501 are disclosed as prior art, so no more details will be given here. Under the action of the torsion spring, the first rotating plate 205 defaults to rotate to a state parallel to the inner plate 201 (as Figure 10 and Figure 11 shown). This state is the initial state of the first rotating plate 205. At this time, the first rotating block 209 abuts against one end of the first rotating groove 208. When the operator needs to hang the hanging seat 2 on the wall-attaching base 1, the operator needs to hold the hanging seat 2 and slide it from one side of the wall-attaching base 1 to its surface. During the hanging process, the operator needs to push up the clamping plate 206 to make the first rotating plate 205 rotate on the first rotating shaft 204. During the rotation process, the plug plate 207 will move away from the plug cylinder 101 on the wall-attaching base 1, thus ensuring that the hanging seat 2 can be slid onto the surface of the wall-attaching base 1 without being blocked and limited by the plug cylinder 101. When the hanging seat 2 slides to the appropriate position, the operator stops pushing the clamping plate 206. Under the action of the torsion spring, the plug plate 207 will automatically be inserted into the plug cylinder 101 on the wall-attaching base 1, that is, the first rotating plate 205 resets to the initial position. After the two are inserted, the plug plate 207 and the plug cylinder 101 can limit the hanging seat 2 to prevent the hanging seat 2 from sliding and shifting. Such a setting ensures that when the guide rail 4 climbs to the bottom of the hanging seat 2, it can be accurately inserted into the hanging seat 2 without the guide rail 4 failing to be inserted due to position deviation, which will affect the climbing efficiency of the guide rail 4. Moreover, under the limiting action of the plug plate 207 and the plug cylinder 101, the stability between the hanging seat 2 and the wall-attaching base 1 can be improved, and thus the firmness of the guide rail 4 can be improved.

[0058] In this embodiment, as Figures 9 to 11 and Figure 14As shown, the anti-falling component further includes a second rotating shaft 5 inserted into the guide rail 4. An installation hole 404 matching the size of the second rotating shaft 5 is provided on the guide rail 4. A nut 510 is screwed on the second rotating shaft 5. Bolts are screwed at both ends of the second rotating shaft 5. A second rotating plate 501 is rotatably connected to the middle position of the second rotating shaft 5. One end of the second rotating plate 501 is fixedly connected with a first inclined plate 504. The first inclined plate 504 abuts against the clamping plate 206. A second rotating block 503 is fixedly connected to the middle position of the second rotating shaft 5. A second rotating groove 502 adapted to the length of the second rotating block 503 is provided at the other end of the second rotating plate 501. A torsion spring is installed between the second rotating shaft 5 and the second rotating plate 501. When an operator installs the second rotating shaft 5 on the guide rail 4, first insert the second rotating shaft 5 into the installation hole 404 on the guide rail 4, and then use the nut 510 to install and fix the second rotating shaft 5. The working principle between the second rotating shaft 5 and the second rotating plate 501 is the same as that between the first rotating shaft 204 and the first rotating plate 205. The second rotating shaft 5 and the second rotating plate 501 are limited by the second rotating block 503 and the second rotating groove 502, and a torsion spring is provided between the second rotating shaft 5 and the second rotating plate 501. Such a setting makes the second rotating plate 501 perpendicular to the inner plate 201 in the initial state. In this state, the first inclined plate 504 abuts against the clamping plate 206 together, and the second rotating block 503 abuts against one end of the second rotating groove 502 (as Figure 10 and Figure 11 shown). When the guide rail 4 climbs up, the first inclined plate 504 will be squeezed with the clamping plate 206. Since the clamping plate 206 has a "V"-shaped profile and the inclined plate has an inclined surface profile, during the squeezing process of the two, the clamping plate 206 will guide the inclined plate to drive the second rotating plate 501 to rotate. During the rotation of the second rotating plate 501, it will avoid the clamping plate 206, thus ensuring that the guide rail 4 can pass through the clamping plate 206 smoothly. When the first inclined plate 504 completely passes through the clamping plate 206, under the action of the torsion spring, the second rotating plate 501 will reset to the initial state. At this time, if the guide rail 4 shows a falling phenomenon, the first inclined plate 504 will directly be inserted into the "V"-shaped profile of the clamping plate 206, and under the limiting action of the second rotating groove 502 and the second rotating block 503, the first inclined plate 504 cannot continue to rotate after being inserted into the clamping plate 206, thus realizing the fixing effect on the guide rail 4 and preventing the guide rail 4 from falling further. Through such a setting, during the climbing process of the guide rail 4, the first inclined plate 504 will automatically avoid under the guiding action of the clamping plate 206, ensuring that the guide rail 4 can pass through the clamping plate 206 smoothly. If a falling phenomenon occurs during the climbing process, at this time, the first inclined plate 504 cooperates with the clamping plate 206 to block and limit the falling guide rail 4, thus achieving the anti-falling effect and ensuring the safety of the climbing of the guide rail 4.

[0059] In this embodiment, as Figures 12 to 14As shown in the figure, third rotating plates 505 are rotatably connected to both ends of the second rotating shaft 5. One end of the third rotating plate 505 is fixedly connected to a second inclined plate 508. The top of the second inclined plate 508 has an inclined surface profile. The bottom of the second inclined plate 508 is fixedly connected to a positioning plate 509. The included angle between the positioning plate 509 and the second inclined plate 508 is ninety degrees. A guiding plate 601 is fixedly connected to the bottom of the reversing box 6. The bottom of the guiding plate 601 has a shape consistent with the inclined surface profile of the second inclined plate 508. Third rotating blocks 507 are fixedly connected to the outer walls of both ends of the second rotating shaft 5. A third rotating groove 506 adapted to the length of the third rotating block 507 is provided at the other end of the third rotating plate 505. A torsion spring is installed between the second rotating shaft 5 and the third rotating plate 505. The working principle and installation method between the third rotating plate 505 and the second rotating shaft 5 are the same as those between the first rotating plate 205 and the first rotating shaft 204, so no more details will be described here. Under the action of the torsion spring, the second inclined plate 508 abuts against the bottom of the guiding plate 601 in the initial state. When the guide rail 4 climbs upward, since the bottom of the guiding plate 601 has a shape consistent with the inclined surface profile of the second inclined plate 508, the guiding plate 601 will squeeze the second inclined plate 508, and drive the third rotating plate 505 to rotate under the guiding action of the inclined surface of the second inclined plate 508. During the rotation of the third rotating plate 505, the second inclined plate 508 avoids the reversing box 6, ensuring that the guide rail 4 can pass through the reversing box 6 smoothly. When the second inclined plate 508 completely passes through the reversing box 6, it will automatically reset to the initial state under the action of the torsion spring. At this time, if the guide rail 4 shows a falling phenomenon, the second inclined plate 508 will abut against the top of the reversing box 6. Since the included angle between the positioning plate 509 and the second inclined plate 508 is ninety degrees, when the second inclined plate 508 abuts against the reversing box 6, the positioning plate 509 will abut against one side of the reversing box 6 (as Figure 12 and Figure 13 shown). At this time, the second inclined plate 508 cooperates with the positioning plate 509 to block and limit the guide rail 4, thereby preventing the guide rail 4 from continuing to fall. Through the setting of the above structure, when the guide rail 4 falls, the second inclined plate 508 cooperates with the positioning plate 509 to provide double-block protection for the guide rail 4, improving the safety of the guide rail 4 when climbing upward.

[0060] The working principle of the technical solution provided by the present invention is as follows:

[0061] During use, first install the second rotating shaft 5 on the guide rail 4: The operator first inserts the second rotating shaft 5 into the installation hole 404 on the guide rail 4, and then uses a nut 510 to install and fix the second rotating shaft 5. Since bolts are screwed at both ends of the second rotating shaft 5, the third rotating plates 505 at both ends of the second rotating shaft 5 can be blocked and limited by the bolts.

[0062] Then install the wall-attached seat 1 into the climbing cone 3: The operator screws the installation bolt 305 into the climbing cone 3. At this time, the installation bolt 305 will squeeze the inner push plate 304 and move fixedly towards the expansion plate 302. Since the overall contour of the climbing cone 3 is conical, when the inner push plate 304 moves towards the fixed end of the expansion plate 302, it will squeeze the expansion plate 302. Since the bending part 303 is installed at the connection position between the expansion plate 302 and the climbing cone 3, and the bending part 303 has an outwardly convex arc-shaped contour, during the process of the inner push plate 304 squeezing the expansion plate 302, it will drive the expansion plate 302 to expand and deform at the position of the bending part 303. During the deformation process of the expansion plate 302, it will squeeze the concrete on the outer wall of the climbing cone 3, thereby improving the firmness of the cooperation between the climbing cone 3 and the concrete and preventing the concrete from cracking and affecting the stability of the climbing cone 3.

[0063] Then install the hanging seat 2 on the wall-attached seat 1: The operator holds the hanging seat 2 and slides it from one side of the wall-attached seat 1 to its surface. During the hanging process, the operator needs to push up the clamping plate 206 to make the first rotating plate 205 rotate on the first rotating shaft 204. During the rotation process, the inserting plate 207 will move away from the inserting cylinder 101 on the wall-attached seat 1, thus ensuring that the hanging seat 2 will not be blocked and limited by the inserting cylinder 101 when it slides and hangs on the surface of the wall-attached seat 1. When the hanging seat 2 slides to the appropriate position, the operator stops pushing the clamping plate 206. Under the action of the torsion spring, the inserting plate 207 will automatically insert into the inserting cylinder 101 on the wall-attached seat 1, that is, the first rotating plate 205 returns to its initial position. After the two are inserted, the inserting plate 207 cooperates with the inserting cylinder 101 to limit the hanging seat 2, preventing the hanging seat 2 from sliding and shifting. Such a setting ensures that when the guide rail 4 climbs to the bottom of the hanging seat 2, it can be accurately inserted into the hanging seat 2, and the insertion failure of the guide rail 4 will not occur due to position deviation, thereby affecting the climbing efficiency of the guide rail 4. Moreover, under the limiting action of the inserting plate 207 and the inserting cylinder 101, the stability between the hanging seat 2 and the wall-attached seat 1 can be improved, thereby improving the firmness of the guide rail 4.

[0064] During the process of climbing on the guide rail 4, the first inclined plate 504 will be mutually extruded with the clamping plate 206. Since the clamping plate 206 has a "V"-shaped contour and the inclined plate has an inclined surface contour, during the extrusion process of the two, the clamping plate 206 will guide the inclined plate to drive the second rotating plate 501 to rotate. During the rotation of the second rotating plate 501, it will avoid the clamping plate 206, thus ensuring that the guide rail 4 can smoothly pass through the clamping plate 206. When the first inclined plate 504 completely passes through the clamping plate 206, under the action of the torsion spring, the second rotating plate 501 will reset to the initial state. At this time, if the guide rail 4 shows a phenomenon of falling, the first inclined plate 504 will directly be inserted into the "V"-shaped contour of the clamping plate 206, and under the limiting action of the second rotating groove 502 and the second rotating block 503, the first inclined plate 504 cannot continue to rotate after being inserted into the clamping plate 206, thereby realizing the fixing effect on the guide rail 4 and preventing the guide rail 4 from continuing to fall. Through such a setting, during the climbing process of the guide rail 4, the first inclined plate 504 will automatically avoid under the guiding action of the clamping plate 206, ensuring that the guide rail 4 can smoothly pass through the clamping plate 206. During the climbing process, if there is a falling phenomenon, at this time, the first inclined plate 504 cooperates with the clamping plate 206 to block and limit the falling guide rail 4, thereby achieving the anti-falling effect and ensuring the safety of the climbing of the guide rail 4; when the guide rail 4 climbs, since the bottom of the guiding plate 601 has a shape consistent with the inclined surface contour of the second inclined plate 508, the guiding plate 601 will extrude the second inclined plate 508, and under the guiding action of the inclined surface of the second inclined plate 508, it will drive the third rotating plate 505 to rotate. During the rotation of the third rotating plate 505, the second inclined plate 508 will avoid the reversing box 6, ensuring that the guide rail 4 can smoothly pass through the reversing box 6. When the second inclined plate 508 completely passes through the reversing box 6, it will automatically reset to the initial state under the action of the torsion spring. At this time, if the guide rail 4 shows a falling phenomenon, the second inclined plate 508 will abut against the top of the reversing box 6. Since the included angle between the positioning plate 509 and the second inclined plate 508 is ninety degrees, when the second inclined plate 508 abuts against the reversing box 6, the positioning plate 509 will abut against one side of the reversing box 6. At this time, the second inclined plate 508 cooperates with the positioning plate 509 to block and limit the guide rail 4, thereby preventing the guide rail 4 from continuing to fall. Through the setting of the above structure, when the guide rail 4 falls, the second inclined plate 508 cooperates with the positioning plate 509 to double-block and protect the guide rail 4, improving the safety of the climbing of the guide rail 4.
