By adjusting the screw-in length of the screw rod in the internal threaded hole of the threaded sleeve, the top surface heights of multiple groups of screw rods at different positions on the roof panel can be kept consistent, thereby ensuring the horizontal placement of the subsequent support platform and improving the structural stability of the entire auxiliary operation platform.

[0007] Furthermore, the operating platform with counterweight includes a supporting platform and a counterweight assembly, the counterweight assembly includes a counterweight limit column and a counterweight block, the counterweight limit column is welded on the supporting platform, and the counterweight block is sleeved on the counterweight limit column. The design is reasonable, and the supporting platform provides an installation support surface for the installation of the operating ladder, ensuring the stable placement of the operating ladder, thereby facilitating the high-altitude installation work of the installers, and the ingenious design of the counterweight assembly can adjust the placement quantity of the counterweight block according to various factors such as the structural balance of the auxiliary operating platform itself and the actual weight of the installers, so that the auxiliary operating platform is in a balanced state as a whole, ensuring that the auxiliary operating platform is in a stable state during the high-altitude climbing and installation construction of the installers, and will not tilt, dump, etc., effectively ensuring the stability of the auxiliary operating platform and improving the operational safety performance.

[0008] Furthermore, the operating ladder includes an outer support column, an inner support column, a side connecting rod and a ladder rod. Two outer support columns and two inner support columns are each provided. Side connecting rods are evenly provided between two adjacent outer support columns. Ladder rods are evenly provided between the outer support column and the inner support column on the corresponding side. An outer support column and an inner support column are combined into a group of side brackets. The operating ladder includes two groups of side brackets.

[0009] Furthermore, a top connecting plate is connected between the top of the outer support column and the top of the inner support column on the corresponding side, and the two ends of the top connecting plate are respectively welded and fixed to the outer support column and the inner support column. Through the design of the top connecting plate, the top of the outer support column and the inner support column on each group of side brackets can be connected and fixed, thereby further improving the structural strength of the side bracket, effectively preventing deformation of the upper part of the side bracket, etc., and improving the structural safety performance.

[0010] Furthermore, support end plates are provided at the bottom of the outer support column and the inner support column, and the support end plates are fixedly connected to the operating platform with counterweight by first high-strength bolts. Through the design of the support end plates, the first high-strength bolts can be used to achieve the installation and fixation of the operating ladder and the support platform, ensuring the installation firmness of the operating ladder and the support platform.

The top surface heights of the operating platform ear plates on the ladder rods at the same height position and the operating platform ear plates on the inner support column are consistent with the top surface height of the ladder rods corresponding to the height. A fixed ear plate is provided on the operating platform plate, and the fixed ear plate is fixedly connected to the operating platform ear plate through a pin shaft. The structural design is reasonable, and the ladder rods on the two sets of side brackets correspond to each other one by one, so that the operating platforms on the two ladder rods at the same height on the operating ladder can be operated. The platform ear plates and the operating platform ear plates on the two inner support columns corresponding to the height are combined to form an installation support surface of an operating platform board. The operating platform board is installed and fixed at the same time by means of four operating platform ear plates, which effectively ensures the installation stability of the operating platform board and improves the operating safety performance. In addition, the top surface heights of the operating platform ear plates on the ladder rod and the operating platform ear plates on the inner support columns at the same height are designed to be consistent with the top surface height of the ladder rod corresponding to the height, which can avoid the height difference from the ladder rod to the operating platform board and is more convenient for actual climbing operations.

[0012] The method for using the auxiliary counterweight operating platform for installing the outer protective plate of the ventilation air building comprises the following steps:

[0013] 1) Install the level height adjustment device:

[0014] (1) Drill a reserved hole on the angle adjustment base plate, and drill a reserved hole on the bottom of the threaded sleeve. The hole passes through the threaded sleeve horizontally to ensure that the diameter of the hole reserved on the threaded sleeve is the same as that of the hole reserved on the angle adjustment base plate, and the diameter of the hole is 1-2 mm larger than the diameter of the second high-strength bolt. Then, the second high-strength bolt is used to temporarily connect and fix the threaded sleeve and the angle adjustment base plate, and the screw rod is screwed into the threaded sleeve. The overall design is reasonable. Drill reserved holes on the angle adjustment base plate and the threaded sleeve to facilitate installation and disassembly between the angle adjustment base plate and the threaded sleeve. The diameter of the reserved hole is designed to be 1-2 mm larger than the diameter of the second high-strength bolt, so that the clearance between the second high-strength bolt and the reserved hole is matched, which is more convenient for the subsequent connection and installation between the second high-strength bolt and the angle adjustment base plate and the threaded sleeve.

[0015] (2) Select six sets of horizontal height adjustment devices, loosen the second high-strength bolt of the horizontal height adjustment device, adjust the angle of the bottom plate according to the slope of the roof panel, and tighten the second high-strength bolt to reinforce it after adjustment; using multiple sets of horizontal height adjustment devices to support and stabilize the support platform at the same time can effectively ensure the stability of the support platform, making the structure of the entire auxiliary operation platform more stable and reliable. The present invention is not limited to six sets of horizontal height adjustment devices. The number of horizontal height adjustment devices can be adjusted according to actual conditions, and the angle of the angle adjustment bottom plate can be adjusted according to the actual slope of the roof panel to ensure the stability of the placement of the horizontal height adjustment device on the roof panel, improve the structural stability of the entire auxiliary operation platform, and make the auxiliary operation platform suitable for roof panels with different types of slopes, with a wider range of applications;

[0016] (3) Place the horizontal height adjustment device on the roof panel and adjust the height of the screw rod in each horizontal height adjustment device until the top heights of all the screw rods are consistent; by adjusting the top heights of the screw rods in multiple groups of horizontal height adjustment devices to be consistent, the support platform can be fixed on the horizontal height adjustment device in a horizontal state, thereby ensuring the structural stability of the operating ladder installed on the support platform, which is more conducive to climbing construction and makes the stability and safety of the entire auxiliary operation platform higher;

[0017] 2) Install the operating platform with counterweight:

[0018] (1) Drill a reserved hole on the top surface of the support platform. The diameter of the reserved hole is 1-2 mm larger than the diameter of the first high-strength bolt. Weld two counterweight limit columns on the support platform. The two counterweight limit columns are respectively welded to the top ends of one side of the counterweight operation platform. The cross-sectional diameter of the selected counterweight limit column is 5-10 mm larger than the diameter of the internal circular hole of the counterweight block. Drilling a reserved hole on the support platform can facilitate the subsequent operation of the installation and fixation between the ladder and the support platform. The diameter of the reserved hole is designed to be 1-2 mm larger than the diameter of the first high-strength bolt, so that the first high-strength bolt can be fixed to the support platform. The clearance between the high-strength bolt and the reserved hole is matched, which is convenient for the installation and insertion of the first high-strength bolt. The counterweight limit column and the support platform are fixed by welding, so that the counterweight limit column and the support platform are combined into one, ensuring the structural stability of the counterweight operation platform. In addition, the cross-sectional diameter of the counterweight limit column is designed to be 5-10mm larger than the diameter of the internal circular hole of the counterweight block, so that the counterweight block and the counterweight limit column are interference fit, ensuring the friction between the counterweight block and the counterweight limit column, so that the counterweight block will not shake after being inserted into the counterweight limit column, etc., effectively improving the balance effect of the counterweight assembly;

[0019] (2) Place the assembled counterweight operating platform on top of the screw rods of the six sets of horizontal height adjustment devices, and ensure that the two counterweight limit columns welded on the counterweight operating platform are set away from the ventilation air tower, and then weld the top of the screw rod to the counterweight operating platform; use welding to fix the counterweight operating platform and the screw rod, effectively ensure the installation firmness of the counterweight operating platform and the horizontal height adjustment device, make the structure of the entire auxiliary operating platform more stable and reliable, and have better safety performance. When placing the counterweight operating platform, ensure that the counterweight operating platform fully covers multiple sets of horizontal height adjustment devices, and at the same time, set the side of the counterweight operating platform close to the counterweight limit column away from the ventilation air tower. The design is reasonable. During the installation process, the installer stands on the operating platform board close to the ventilation air tower on the operating ladder, so that the side of the auxiliary operating platform close to the ventilation air tower has a large weight. In order to balance, gravity must be added to the side of the auxiliary operating platform away from the ventilation air tower for balance. Therefore, the counterweight component should be set away from the ventilation air tower to facilitate the subsequent balance adjustment of the entire device;

[0020] 3) Install the operating ladder:

[0021] (1) Two inner support columns are manufactured according to the structural shape of the ventilation tower, so that the upper curvature of the inner support columns matches the structural shape of the ventilation tower. Then, the sizes of the two outer support columns are determined according to the sizes of the inner support columns and they are manufactured. Support end plates are welded at the bottom ends of the two inner support columns and the two outer support columns, and reserved holes are drilled on the support end plates. The diameter of the holes is 1-2 mm larger than the diameter of the first high-strength bolts. The inner support columns are manufactured according to the outer structure design of the ventilation tower, so that it is convenient to control the distance between the operating platform plate and the position of the outer protective plate to be installed on the ventilation tower, thereby facilitating the subsequent construction process and making the design more ingenious and reasonable. The support end plates are welded at the bottom of the inner support columns and the outer support columns, which can facilitate the installation and fixation between the operating ladder and the support platform. By drilling reserved holes on the support short plate, the holes correspond to the holes on the support platform, which is convenient for installation. Moreover, the diameter of the holes is 1-2 mm larger than the diameter of the first high-strength bolts, so that the clearance between the first high-strength bolts and the reserved holes is matched, which is convenient for the installation and insertion of the first high-strength bolts.

[0022] (2) Divide the two inner support columns and the two outer support columns into two groups. Combine one inner support column and one outer support column into a side bracket. Evenly weld ladder rods between the outer support columns and the inner support columns on each side bracket. After welding, weld an ear plate for the operating platform to the middle and upper part of each ladder rod on each side bracket. And weld an ear plate for the operating platform at the height position of the inner support column corresponding to the height of each ladder rod on each side bracket. Ensure that the top surface heights of the ear plates for the operating platform on the ladder rods and the ear plates for the operating platform on the inner support columns at the same height position are consistent with the top surface heights of the ladder rods corresponding to the height. Then weld a top connecting rod to the top of the outer support columns and the inner support columns on each side bracket. Use a connecting rod between the ladder rod and the outer support columns and the inner support columns. The side bracket is welded and fixed, thereby effectively ensuring the structural stability of the side bracket. The top of the outer support column and the inner support column are reinforced and welded by using a top connecting rod to effectively prevent deformation and bending of the upper part of the side bracket. The operating platform ear plates are welded on the ladder rod and the inner support column. Four operating platforms at the same height form an installation support surface. The operating platform plate is installed and fixed at the same time by four operating platform ear plates, which effectively ensures the installation stability of the operating platform plate and improves the operating safety performance. In addition, the top surface heights of the operating platform ear plates on the ladder rod and the operating platform ear plates on the inner support column at the same height are designed to be consistent with the top surface height of the ladder rod corresponding to the height, which can avoid the height difference from the ladder rod to the operating platform plate, making it more convenient for actual climbing operations.

[0023] (3) A side connecting rod is welded between the outer supporting columns on the two sets of side brackets to connect the two sets of side brackets into one, and then the whole combination of the two sets of side brackets is fixed to the top surface of the counterweight operating platform by the first high-strength bolt; the outer supporting columns on the two sets of side brackets are fixed by the side connecting rod to further improve the structural stability of the operating ladder, so that the safety performance of the entire auxiliary operating platform is higher, and the operating ladder and the supporting platform are fixed by the first high-strength bolt to ensure the installation firmness of the operating ladder and the supporting platform. The connection method is simple and convenient, and the operating ladder and the supporting platform are designed to be a detachable structure, which can be convenient for packaging and transportation, etc. The structural design is ingenious and reasonable;

[0024] (4) The operating platform board is fixed to the ear plate of the operating platform by a pin shaft; the operating platform board can be fixed and placed at different heights by the pin shaft. The installation method is simple and reasonable, and the installation is firm, which ensures the structural stability of the operating platform board and makes the operation safer and more reliable;

[0025] 4) Installation of the outer protective plate: After the auxiliary operating platform is placed and installed, the number of counterweights is increased according to the actual installation and construction conditions to ensure that the auxiliary operating platform is in a balanced state. The installers then climb onto the operating platform board through the ladder rod to install the outer protective plate of the ventilation tower. When the outer protective plate at that height is installed and it is necessary to install the outer protective plate at other heights, the operating platform board is disassembled, and then the operating platform board is installed to the ear plate of the operating platform at the corresponding height through the pin according to the height of the outer protective plate to be installed, until the installation of the outer protective plate of all heights is completed; the number of counterweights to be placed is determined according to the actual weight of the installers and the structural balance of the auxiliary operating platform itself, so as to ensure that the auxiliary platform remains in a balanced state during the construction process of the installers, improve the construction safety performance, and prevent tilting and tipping during use. Moreover, during the installation of the outer protective plate of the ventilation tower, the operating platform board can be installed and fixed to the corresponding height for the installation of the outer protective plate at different heights, so as to facilitate the construction and installation of the outer protective plate at that height, and the entire installation and construction process is safe and reliable.

[0026] Furthermore, in step (3) of step 1), before placing the horizontal height adjustment device on the roof panel, a fireproof film is first laid on the roof panel below the welding position, and a fireproof film is laid on the roof panel corresponding to the construction position. The roof panel is protected by the fireproof film to prevent the auxiliary operation platform from scratching and damaging the panel, and to prevent electric welding slag from falling and damaging the roof during welding operations during construction.

[0027] Furthermore, in step (3) of step 1), after the horizontal height adjusting device is placed on the roof panel, the position of each set of horizontal height adjusting devices on the roof panel is appropriately adjusted so that the horizontal height adjusting device is just supported by the purlin below after being placed on the roof panel, and the position of each set of horizontal height adjusting devices is adjusted so that the bottom of each set of horizontal height adjusting devices is just supported by the purlin after being placed, thereby further improving the stability of the placement of the horizontal height adjusting device on the roof panel, making the structure of the entire auxiliary operation platform more stable and reliable, and facilitating actual construction operations.

[0028] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0029] The overall design of the present invention is ingenious and reasonable.

[0057] (1) Drill a reserved hole on the angle adjustment base plate 6, and drill a reserved hole at the bottom of the threaded sleeve 7. The hole horizontally penetrates the threaded sleeve 7, ensuring that the reserved hole on the threaded sleeve 7 has the same diameter as the reserved hole on the angle adjustment base plate 6, and the diameter of the hole is 1-2 mm larger than the diameter of the second high-strength bolt 9. Then, the second high-strength bolt 9 is used to temporarily connect and fix the threaded sleeve 7 and the angle adjustment base plate 6, and the screw 8 is screwed into the threaded sleeve 7. The overall design is reasonable. Drill reserved holes on the angle adjustment base plate 6 and the threaded sleeve 7 to facilitate installation and disassembly between the angle adjustment base plate 6 and the threaded sleeve 7. In addition, the diameter of the reserved hole is designed to be 1-2 mm larger than the diameter of the second high-strength bolt 9, so that the clearance between the second high-strength bolt 9 and the reserved hole is matched, which is more convenient for the subsequent connection and installation between the second high-strength bolt 9 and the angle adjustment base plate 6 and the threaded sleeve 7.

[0058] (2) Select six sets of horizontal height adjustment devices 1, loosen the second high-strength bolts 9 of the horizontal height adjustment devices 1, adjust the angle of the angle adjustment bottom plate 6 according to the slope of the roof panel 24, and tighten the second high-strength bolts 9 to reinforce it after adjustment; using multiple sets of horizontal height adjustment devices 1 to support and stabilize the support platform 10 at the same time can effectively ensure the stability of the placement of the support platform 10, making the structure of the entire auxiliary operation platform more stable and reliable. The present invention is not limited to six sets of horizontal height adjustment devices 1. The number of horizontal height adjustment devices 1 can be adjusted according to actual conditions, and the angle of the angle adjustment bottom plate 6 can be adjusted according to the actual slope of the roof panel 24 to ensure the stability of the placement of the horizontal height adjustment device 1 on the roof panel 24, improve the structural stability of the entire auxiliary operation platform, and make the auxiliary operation platform applicable to roof panels 24 of different types of slopes, with a wider range of applications;

[0059] (3) First, lay a fireproof film on the roof panel 24 below the welding position, and lay a fireproof film on the roof panel 24 corresponding to the construction position. The fireproof film is used to protect the roof panel 24 to prevent the auxiliary operation platform from scratching and damaging the panel. At the same time, it is prevented that the welding slag falls and damages the roof during the welding operation. The horizontal height adjustment device 1 is placed on the roof panel 24, and the position of each set of horizontal height adjustment devices 1 on the roof panel 24 is appropriately adjusted so that the horizontal height adjustment device 1 is placed on the roof panel 24 and is supported by the purlin below. The position of each set of horizontal height adjustment devices 1 is adjusted so that the bottom of each set of horizontal height adjustment devices 1 is directly supported by the purlin below. It is better to have purlin support, so as to further improve the stability of the placement of the horizontal height adjustment device 1 on the roof panel 24, so that the structure of the entire auxiliary operation platform is more stable and reliable, which is convenient for actual construction operations, and the height of the screw rod 8 in each horizontal height adjustment device 1 is adjusted until the top height of all the screw rods 8 is consistent; the top heights of the screw rods 8 in multiple groups of horizontal height adjustment devices 1 are adjusted to be consistent, so that the support platform 10 can be fixed on the horizontal height adjustment device 1 in a horizontal state, thereby ensuring the structural stability of the operating ladder 3 installed on the support platform 10, which is more conducive to climbing construction, and the stability and safety of the entire auxiliary operation platform are higher;

[0060] 2) Install the operating platform with counterweight 2:

[0061] (1) Drill a reserved hole on the top surface of the support platform 10, the diameter of the reserved hole is 1-2 mm larger than the diameter of the first high-strength bolt 4, weld two counterweight limit columns 12 on the support platform 10, and weld the two counterweight limit columns 12 to the top ends of one side of the counterweight operation platform 2, and the cross-sectional diameter of the selected counterweight limit column 12 is 5-10 mm larger than the internal circular hole diameter of the counterweight block 13; drilling a reserved hole on the support platform 10 can facilitate the subsequent operation of the installation and fixation between the ladder 3 and the support platform 10, and the diameter of the reserved hole is designed to be 1-2 mm larger than the diameter of the first high-strength bolt 4, so that the first high-strength bolt 4 and The clearance between the reserved holes is matched to facilitate the installation and insertion of the first high-strength bolt 4. The counterweight limit column 12 and the support platform 10 are fixed by welding, so that the counterweight limit column 12 and the support platform 10 are combined into one body to ensure the structural stability of the counterweight operation platform. The cross-sectional diameter of the counterweight limit column 12 is designed to be 5-10mm larger than the internal circular hole diameter of the counterweight block 13, so that the counterweight block 13 and the counterweight limit column 12 are interference fit, ensuring the friction between the counterweight block 13 and the counterweight limit column 12, so that the counterweight block 13 will not shake after being inserted into the counterweight limit column 12, etc., effectively improving the balancing effect of the counterweight assembly 11;

[0062] (2) Place the assembled counterweight operating platform 2 on the top of the screw rod 8 of the six sets of horizontal height adjustment devices 1, and ensure that the two counterweight limit columns 12 welded on the counterweight operating platform 2 are set away from the ventilation air tower, and then weld and fix the top of the screw rod 8 to the counterweight operating platform 2; Use welding to fix the counterweight operating platform 2 and the screw rod 8, effectively ensuring the installation firmness of the counterweight operating platform 2 and the horizontal height adjustment device 1, making the structure of the entire auxiliary operating platform more stable and reliable, with better safety performance, and placing the counterweight operating platform 2 to ensure that The counterweight operating platform 2 is kept to fully block the multiple sets of horizontal height adjustment devices 1, and at the same time, the side of the counterweight operating platform 2 close to the counterweight limit column 12 is set away from the ventilation air building. The design is reasonable. During the installation and construction process, the installer stands on the operating platform board 5 close to the ventilation air building on the operating ladder 3, so that the side of the auxiliary operating platform close to the ventilation air building has a large weight. In order to balance, gravity must be added to the side of the auxiliary operating platform away from the ventilation air building for balance. Therefore, the counterweight assembly 11 should be set away from the ventilation air building, which is convenient for the subsequent balance adjustment of the entire device.

[0063] 3) Installation and operation ladder 3:

[0064] (1) Two inner support columns 15 are manufactured according to the structural shape of the ventilation tower, so that the upper curvature of the inner support column 15 matches the structural shape of the ventilation tower.

[0065] (2) The two inner support columns 15 and the two outer support columns 14 are divided into two groups. One inner support column 15 and one outer support column 14 are combined into a group of side brackets. The ladder rods 17 are evenly welded between the outer support columns 14 and the inner support columns 15 on each group of side brackets. After the welding is completed, the ear plates 20 for the operating platform are welded to the middle and upper parts of each ladder rod 17 on each group of side brackets. The ear plates 20 for the operating platform are welded at the height position of the inner support columns 15 corresponding to the height of each ladder rod 17 on each group of side brackets.

Four operating platforms at the same height form an installation support surface. The operating platform board 5 is installed and fixed at the same time by four operating platform ear plates 20, which effectively ensures the installation stability of the operating platform board 5 and improves the operating safety performance. In addition, the top surface heights of the operating platform ear plates 20 on the ladder rod 17 and the operating platform ear plates 20 on the inner support column 15 at the same height are designed to be consistent with the top surface height of the ladder rod 17 corresponding to the height, which can avoid the height difference from the ladder rod 17 to the operating platform board 5, making it more convenient for actual climbing operations.

[0066] (3) A side connecting rod 16 is welded between the outer supporting columns 14 on the two sets of side brackets to connect the two sets of side brackets into one, and then the whole combination of the two sets of side brackets is fixed to the top surface of the counterweight operating platform 2 by the first high-strength bolt 4; the outer supporting columns 14 on the two sets of side brackets are fixed by the side connecting rod 16, so as to further improve the structural stability of the operating ladder 3, so that the safety performance of the entire auxiliary operating platform is higher, and the operating ladder 3 and the supporting platform 10 are fixed by the first high-strength bolt 4 to ensure the installation firmness of the operating ladder 3 and the supporting platform 10.
