The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. In the prior art, a patent document with publication number CN114873443B discloses a fixing device for lifting a building steel structure, including a hanging plate and a receiving plate evenly arranged and symmetrically installed at the lower end of the hanging plate, a tightening mechanism is installed between every two corresponding receiving plates on the left and right, and a receiving mechanism is installed between every two corresponding receiving plates on the left and right. The tightening mechanism and the receiving mechanism are arranged alternately. During use, the above-mentioned device adopts a method of cooperating with the tightening mechanism and the receiving mechanism, so as to perform double fixation on both the I-shaped steel structure and the cylindrical steel structure. However, when the above-mentioned lifting device is working, on the one hand, it is not convenient to realize the synchronous magnetic attraction positioning, side clamp positioning and lower limit positioning of the steel structure, and on the other hand, it is not convenient to adjust the lifting specifications and perform self-adjusting balance during the lifting operation, which leads to limited safety improvement of the lifting device. Based on this, the present invention provides a material lifting method for building steel structure construction to solve the problems raised in the above-mentioned background technology. Summary of the invention

[0003] The present invention aims at the technical problems existing in the prior art and provides a material hoisting method for building steel structure construction to solve the problem that when the existing hoisting device is working, on the one hand, it is not convenient to achieve synchronous magnetic positioning, side clamp positioning and lower limit positioning of the steel structure; on the other hand, it is not convenient to adjust the hoisting specifications and perform self-adjusting balance during the hoisting operation, which subsequently leads to limited safety improvement of the hoisting device.

[0004] The technical solution of the present invention to solve the above technical problems is as follows: A material hoisting method for building steel structure construction comprises the following steps: SS01. Laying out: Before hoisting materials for building steel structure construction, a hoisting machine and a hoisting device are pre-installed, and the hoisting machine pulls the hoisting device through the hoisting cable; SS02, hoisting. During hoisting, the specifications of the corresponding structures in the hoisting device are adjusted according to the specifications of the steel structure to be hoisted, and finally the hoisting specifications of the hoisting device are adapted to the specifications of the steel structure to be hoisted. After the adjustment is completed, the hoisting device simultaneously realizes the hoisting and fixing of the steel structure to be hoisted through double-sided side clamps, bottom clamps and magnetic suspension clamps; The lifting device includes a hanger and a balance frame. The hanger is equipped with a gravity balancing mechanism, which is used to make the load-bearing of the balance frame uniform. The balance frame is equipped with an air pump. Clamp frames are provided on both sides of the balance frame. Scissor-type mounting mechanisms are installed between the two clamp frames and the balance frame. The port of the air pump is connected to a soft air pipe. Each of the scissor-type mounting mechanisms is equipped with a group of clamping components with adjustable spacing, and each clamping component is connected to the soft air pipe. A lifting cable module is installed between the two clamp frames and the balance frame.

[0005] Based on the above technical solution, the present invention can also be improved as follows.

[0006] Furthermore, the gravity balancing mechanism includes two symmetrically arranged tension sensors and a linear transmission module installed between the inner surfaces of the hanger, the linear transmission module is transmission-connected with a positioning platform, the positioning platform is installed with a hinge shaft, both ends of the hinge shaft are hinged to the balance frame, the top ends of the two tension sensors are hinged to the positioning platform, the bottom ends of the two tension sensors are hinged to the balance frame, the hinge shaft is arranged between the two tension sensors, a single-chip microcomputer is installed on the hanger, and the data ends of the two tension sensors are connected to the data of the single-chip microcomputer.

[0007] The beneficial effect of adopting the above-mentioned further scheme is that during the material lifting operation, two tension sensors are set to monitor the load-bearing range on both sides of the balance frame respectively. When the load-bearing range on both sides of the balance frame is different, the feedback data of the two tension sensors are different. After the two tension sensors generate data feedback, the feedback data is input into the single-chip microcomputer in real time. The single-chip microcomputer controls the operation of the linear transmission module based on the data feedback of the two tension sensors. After the linear transmission module works, the relative position of the balance frame and the hanger is adjusted. Finally, the tension direction of the hanger is coaxial with the center of gravity of the balance frame. By maintaining the coaxiality between the tension direction of the hanger and the center of gravity of the balance frame, the load-bearing uniformity of the balance frame and the balance of the balance frame during lifting operations are effectively improved, thereby effectively ensuring the lifting safety and stability of the balance frame.

[0008] Furthermore, the scissors-type mounting mechanism includes a scissors-type telescopic frame installed between the balance frame and the clamping frame, a driving screw rotatably connected to the balance frame and a motor fixed to the balance frame, the output shaft end of the motor is fixedly connected to the driving screw, and the scissors-type telescopic frame is driven to extend and retract by the driving screw. The scissors-type telescopic frame includes a group of "X"-shaped frames hinged in sequence, and pipe sleeves are provided at the hinges of each of the "X"-shaped frames.

[0009] The beneficial effect of adopting the above further scheme is that when the hoisting operation of the building steel structure material is carried out, the two motors work synchronously, and after the two motors work, they drive the two driving screws to rotate at the same speed, and after the two driving screws rotate at the same speed, they drive the two scissor-type telescopic frames to extend and retract synchronously, and after the two scissor-type telescopic frames extend and retract synchronously, the distance between the clamping parts is quickly changed; By adjusting the distance between the clamping parts, the hoisting specifications of the hoisting device can be adapted to the specifications of the steel structure to be hoisted; By achieving the above technical effects, the hoisting device is suitable for hoisting operations of building steel structures of various specifications, thereby effectively improving the applicable scenarios and versatility of the device.

[0010] Furthermore, the cable module includes a roller rotatably connected to the balance frame, the roller is transmission-connected to a driving screw at a corresponding position through a chain belt, two symmetrically arranged traction cables are wound on the roller, and the other ends of the two traction cables are fixedly connected to the clamping frame.

[0011] The beneficial effect of adopting the above further scheme is that when the scissors-type telescopic frame is adjusting the telescopic range, the winding roller is driven to rotate, and after the winding roller rotates, the traction cable is then driven to be retracted and unwound. The retracting and unwinding effect is achieved by the linkage between the scissors-type telescopic frame and the traction cable, thereby effectively improving the structural strength and load-bearing strength of the clamping frame.

[0012] Furthermore, the clamping component includes a carrier and an air distribution pipe, the carrier is slidably connected with two slides, the two slides are each installed with a connecting rod, the two connecting rods are rotatably connected to the pipe sleeves at corresponding positions, the carrier is rotatably connected with an adjusting screw, the adjusting screw is symmetrically provided with a positive thread portion and a negative thread portion, the positive thread portion and the negative thread portion are both transmission-connected with a jaw module connected with the air distribution pipe, the carrier is rotatably connected with a gear shaft, the gear shaft and the adjusting screw are both installed with bevel gears, the two bevel gears are meshed with each other, the carrier is installed with a pneumatic push rod, the air inlet end and the air distribution pipe of the pneumatic push rod are both connected with the soft air pipe, the movable end of the pneumatic push rod is installed with a gear plate, the gear shaft is installed with a driven gear, and the driven gear is transmission-connected with the gear plate.

[0013] The beneficial effect of adopting the above further scheme is that the air pump is a dual-purpose pump for suction, that is, the air pump can perform both air supply and exhaust operations. When the telescopic range of the scissor-type telescopic frame is adjusted and it is necessary to perform a clamping operation of the building steel structure, the screw rod is adjusted to rotate by driving and controlling the pneumatic push rod according to the specifications of the building steel structure to be hoisted. After the screw rod is adjusted to rotate, the two jaw modules can be synchronously approached or synchronously moved away from each other. By the two jaw modules approaching or moving away from each other, the distance between the two jaw modules is quickly changed. By changing the distance between the two jaw modules, the building steel structure is effectively clamped. When the clamping operation is in progress, the clamping specifications of each clamping component can be adjusted independently. By achieving the above-mentioned multi-point clamping and independent clamping effects, the device is suitable for hoisting operations of special-shaped or irregular building steel structures.

[0014] Furthermore, the jaw module includes an inner clamp and an outer clamp, both of which are slidably connected to the carrier, the inner clamps on the two jaw modules are respectively transmission-connected to the positive threaded portion and the negative threaded portion, a pressure spring is provided on the adjusting screw rod and corresponds to the position between the inner clamp and the outer clamp, an electromagnetic suction block is slidably connected to the outer clamp, and a plate clamp portion is provided on the outer clamp and corresponds to the position below the electromagnetic suction block.

[0015] The beneficial effect of adopting the above further solution is that, when in use, by arranging the inner clamp, the outer clamp and the pressure spring, the clamping component is suitable for hoisting operations of asymmetric, non-standard or special-shaped building steel structures.

[0016] Furthermore, the pneumatic push rod and the connection point between the air distribution pipe and the soft air pipe are all provided with a solenoid valve and an air pressure probe, and the data end of the air pressure probe is connected to the single chip microcomputer data.

[0017] The beneficial effect of adopting the above further scheme is that, through the setting of the solenoid valve and the air pressure probe, the air intake and air output of the pneumatic push rod in each clamping component can be independently controlled, thereby independently adjusting the state of the protective bag of the pneumatic push rod, and the solenoid valve is controlled by a single-chip microcomputer.

[0018] Furthermore, the jaw module also includes a hanging arm slidably connected to the outer clamp, the top of the hanging arm is fixedly provided with a limiting ring limited by the outer clamp, the bottom end of the hanging arm is installed with a touch ball, an air cavity is fixedly opened inside the hanging arm, the air cavity is connected to the air distribution pipe, and a protective bag is installed on the hanging arm and at a position relative to the plate clamp, and the inner cavity of the protective bag is connected to the air cavity.

[0019] The beneficial effect of adopting the above further scheme is that when the hoisting device is in a non-hoisting state, the gas inside the protective bag is fully emptied. After the gas inside the protective bag is emptied, the protective bag is hidden in the vertical arm. When the hoisting device is in a laying state, the vertical arm slides under the action of external force and freely changes the position of the vertical arm on the external clamp. When the hoisting device is in a hoisting state, the vertical arm moves downward under the action of gravity. When the vertical arm has fully moved downward, the air pump inflates the interior of the protective bag with sufficient air until the air pressure value inside the air distribution pipe reaches the set value. When the air pressure value inside the protective bag reaches the set value, the protective bag is then fully limited to the building steel structure from the bottom of the steel structure to be hoisted. By realizing the lower limit function of the building steel structure, the phenomenon of the building steel structure falling during hoisting is effectively reduced. When the building steel structure needs to be removed from the lifting device, the gas inside the protective bag is fully emptied; When in the lifting state, the electromagnetic suction block fits the building steel structure and magnetically positions the building steel structure; By realizing the magnetic positioning, side clamp positioning and lower limit functions, the stability of the building steel structure during hoisting is effectively guaranteed.

[0020] The beneficial effects of the present invention are: 1. During the hoisting operation, the present invention can realize magnetic positioning, side clamp positioning and lower limit during the hoisting of the steel structure, thereby effectively ensuring the stability of the building steel structure in the hoisting state. On the other hand, the hoisting device can adjust the hoisting specifications during the hoisting operation and is suitable for hoisting operations of special-shaped or irregular building steel structures, thereby effectively improving the functionality and flexibility of use of the hoisting device. Moreover, the hoisting device can automatically balance the steel structure during the hoisting operation, thereby effectively improving the hoisting safety of the device.

[0021] 2. In the present invention, the spacing between the clamping components is adjusted so that the lifting specifications of the lifting device can be adapted to the specifications of the steel structure to be lifted. By achieving the above-mentioned technical effects, the lifting device is suitable for lifting operations of building steel structures of multiple specifications, thereby effectively improving the applicable scenarios and versatility of the device. By setting the inner clamp, the outer clamp and the pressure spring, the clamping components are suitable for lifting operations of asymmetric, non-standard or special-shaped building steel structures.

[0022] 3. During the material hoisting operation, the present invention respectively monitors the load-bearing range on both sides of the balance frame through the setting of two tension sensors. When the load-bearing range on both sides of the balance frame is different, the feedback data of the two tension sensors are different. After the two tension sensors generate data feedback, the feedback data is input into the single-chip microcomputer in real time. The single-chip microcomputer controls the operation of the linear transmission module according to the data feedback of the two tension sensors. After the linear transmission module works, the relative position of the balance frame and the hanger is adjusted. Finally, the tension direction of the hanger is coaxial with the center of gravity of the balance frame. By maintaining the coaxiality between the tension direction of the hanger and the center of gravity of the balance frame, the load-bearing uniformity of the balance frame and the balance of the balance frame during the hoisting operation are effectively improved, thereby effectively ensuring the hoisting safety and stability of the balance frame.

[0023] 4. When the present invention is working, when the hoisting device is in a non-hoisting state, the gas inside the protective bag is fully emptied. After the gas inside the protective bag is emptied, the protective bag is hidden in the hanging arm. When the hoisting device is in a laying state, the hanging arm slides under the action of external force and freely changes the position of the hanging arm on the external clamp. When the hoisting device is in a hoisting state, the hanging arm moves downward under the action of gravity. When the hanging arm has fully moved downward, the air pump inflates the inside of the protective bag with sufficient air until the air pressure value inside the air distribution pipe reaches the set value. When the air pressure value inside the protective bag reaches the set value, the air pump inflates the inside of the protective bag with sufficient air until the air pressure value inside the air distribution pipe reaches the set value. After the value is set, the protective bag will fully limit the building steel structure from the bottom of the steel structure to be hoisted. By realizing the lower limit function of the building steel structure, the falling phenomenon of the building steel structure during lifting is effectively reduced. When the building steel structure needs to be removed from the lifting device, the gas inside the protective bag is fully discharged, and in the lifting state, the electromagnetic suction block fits with the building steel structure and magnetically positions the building steel structure. By realizing the magnetic positioning, side clamp positioning and lower limit functions, the stability of the building steel structure in the lifting state is effectively guaranteed.

[0027] The present invention provides the following preferred embodiments like Figure 1-9 As shown, the material hoisting method for building steel structure construction includes the following steps: SS01. Laying out. Before hoisting materials for building steel structure construction, a hoisting machine and a hoisting device 1 are preset, and the hoisting machine pulls the hoisting device 1 through a hoisting cable; SS02, hoisting. During hoisting, the specifications of the corresponding structure in the hoisting device 1 are adjusted according to the specifications of the steel structure 2 to be hoisted, and finally the hoisting specifications of the hoisting device 1 are adapted to the specifications of the steel structure 2 to be hoisted. After the adjustment is completed, the hoisting device 1 synchronously realizes the hoisting and fixing of the steel structure 2 to be hoisted by means of double-sided side clamps, bottom clamps and magnetic suspension clamps; The hoisting device 1 comprises a hanger 3 and a balance frame 4. A gravity balance mechanism is installed on the hanger 3, and the gravity balance mechanism is used to make the load-bearing of the balance frame 4 uniform. The gravity balancing mechanism includes two symmetrically arranged tension sensors 8 and a linear transmission module 9 installed between the inner surfaces of the hanger 3. The linear transmission module 9 is transmission-connected with a positioning platform 10, and a hinge shaft is installed on the positioning platform 10. Both ends of the hinge shaft are hinged to the balance frame 4. The top ends of the two tension sensors 8 are hinged to the positioning platform 10, and the bottom ends of the two tension sensors 8 are hinged to the balance frame 4. The hinge shaft is arranged between the two tension sensors 8. A single-chip computer 11 is installed on the hanger 3, and the data ends of the two tension sensors 8 are data-connected to the single-chip computer 11.

[0028] During material hoisting operations, two tension sensors 8 are set up to monitor the load-bearing range on both sides of the balance frame 4 respectively. When the load-bearing range on both sides of the balance frame 4 is different, the feedback data of the two tension sensors 8 are different. After the two tension sensors 8 generate data feedback, the feedback data is input into the single-chip microcomputer 11 in real time. The single-chip microcomputer 11 controls the operation of the linear transmission module 9 based on the data feedback of the two tension sensors 8. After the linear transmission module 9 works, the relative position of the balance frame 4 and the hanger 3 is adjusted. Finally, the tension direction of the hanger 3 is coaxial with the center of gravity of the balance frame 4. By keeping the tension direction of the hanger 3 coaxial with the center of gravity of the balance frame 4, the load-bearing uniformity of the balance frame 4 and the balance of the balance frame 4 during the hoisting operation are effectively improved, thereby effectively ensuring the hoisting safety and stability of the balance frame 4.

[0029] An air pump 5 is installed on the balance frame 4, and clamp frames 6 are provided on both sides of the balance frame 4. A scissor-type mounting mechanism is installed between the two clamp frames 6 and the balance frame 4; The port of the air pump 5 is connected to a soft air pipe 7 , a group of clamping components with adjustable spacing are installed on each scissor-type mounting mechanism, each clamping component is connected to the soft air pipe 7 , and a cable module is installed between the two clamp frames 6 and the balance frame 4 .

[0030] The scissor-type mounting mechanism includes a scissor-type telescopic frame 12 installed between the balance frame 4 and the clamping frame 6, a driving screw rod 13 rotatably connected to the balance frame 4 and a motor 14 fixed to the balance frame 4, the output shaft end of the motor 14 is fixedly connected to the driving screw rod 13, and the scissor-type telescopic frame 12 is driven to extend and retract by the driving screw rod 13. The scissor-type telescopic frame 12 includes a group of "X"-shaped frames hinged in sequence, and pipe sleeves 15 are provided at the hinges of the two "X"-shaped frames.

[0031] When the lifting operation of the building steel structure material is performed, the two motors 14 work synchronously. After the two motors 14 work, they drive the two driving screws 13 to rotate at the same speed. After the two driving screws 13 rotate at the same speed, they drive the two scissor-type telescopic frames 12 to extend and retract synchronously. After the two scissor-type telescopic frames 12 extend and retract synchronously, the distance between the clamping parts is quickly changed. By adjusting the distance between the clamping parts, the hoisting specifications of the hoisting device 1 can be adapted to the specifications of the steel structure 2 to be hoisted; By achieving the above technical effects, the hoisting device 1 is suitable for hoisting operations of building steel structures of various specifications, thereby effectively improving the applicable scenarios and versatility of the device.

[0032] The cable module includes a roller 16 rotatably connected to the balance frame 4. The roller 16 is transmission-connected to a driving screw 13 at a corresponding position through a chain belt. Two symmetrically arranged traction cables 17 are wound on the roller 16. The other ends of the two traction cables 17 are fixedly connected to the clamp frame 6.

[0033] When the scissors-type telescopic frame 12 is adjusted for telescopic range, the winding roller 16 is driven to rotate, and after the winding roller 16 rotates, the traction cable 17 is driven to be retracted and unreeled. The retracting and unreeling effect is achieved by the linkage between the scissors-type telescopic frame 12 and the traction cable 17, thereby effectively improving the structural strength and load-bearing strength of the clamping frame 6.

[0034] The clamping component includes a carrier 18 and an air distribution pipe 19. Two slides 20 are slidably connected to the carrier 18. Connecting rods 21 are installed on the two slides 20.

A pneumatic push rod 24 is installed on the carrier 18. The air inlet end of the pneumatic push rod 24 and the air distribution pipe 19 are connected to the soft air pipe 7. A tooth plate 25 is installed on the movable end of the pneumatic push rod 24. A driven gear 26 is installed on the gear shaft 23. The driven gear 26 is transmission-connected to the tooth plate 25.

[0035] The air pump 5 is a dual-purpose pump for suction, that is, the air pump 5 can perform both air supply and exhaust operations. When the telescopic range of the scissor-type telescopic frame 12 is adjusted and it is necessary to perform a clamping operation on the building steel structure, the screw rod 22 is rotated by driving and controlling the pneumatic push rod 24 according to the specifications of the building steel structure to be hoisted. After the screw rod 22 is rotated, the two jaw modules can be synchronously approached or moved away from each other. By the two jaw modules approaching or moving away from each other, the distance between the two jaw modules is quickly changed. By changing the distance between the two jaw modules, the building steel structure can be effectively clamped. When the clamping operation is in progress, the clamping specifications of each clamping component can be adjusted independently. By achieving the above-mentioned multi-point clamping and independent clamping effects, the device is suitable for hoisting operations of special-shaped or irregular building steel structures.

[0036] The jaw module includes an inner clamp 27 and an outer clamp 28, both of which are slidably connected to the carrier 18. The inner clamps 27 on the two jaw modules are respectively transmission-connected to the positive threaded portion and the negative threaded portion. A pressure spring 29 is sleeved on the adjusting screw 22 and corresponds to the position between the inner clamp 27 and the outer clamp 28. An electromagnetic suction block 30 is slidably connected to the outer clamp 28, and a plate clamp portion 31 is provided on the outer clamp 28 and corresponds to the position below the electromagnetic suction block 30.

[0037] When in use, the inner clamp 27, the outer clamp 28 and the pressure spring 29 are arranged so that the clamping component is suitable for hoisting operations of asymmetric, non-standard or special-shaped building steel structures.

[0038] The pneumatic push rod 24 and the connecting points of the air distribution pipe 19 and the soft air pipe 7 are all provided with a solenoid valve and an air pressure probe, and the data end of the air pressure probe is connected to the single chip microcomputer 11 for data.

[0039] By setting up the solenoid valve and the air pressure probe, the air intake and air exhaust of the pneumatic push rod 24 in each clamping component can be independently controlled, so as to independently adjust the state of the protective bag 33 of the pneumatic push rod 24. The solenoid valve is controlled by the single chip microcomputer 11.

[0041] When the hoisting device 1 is in a non-hoisting state, the gas inside the protective bag 33 is fully emptied. After the gas inside the protective bag 33 is emptied, the protective bag 33 is hidden in the hanging arm 32. When the hoisting device 1 is in a laying state, the hanging arm 32 slides under the action of external force and freely changes the position of the hanging arm 32 on the outer clamp 28. When the hoisting device 1 is in a hoisting state, the hanging arm 32 moves downward under the action of gravity. After the hanging arm 32 has fully moved downward, the air pump 5 inflates the inside of the protective bag 33 until the air pressure value inside the air distribution pipe 19 reaches the set value. When the air pressure value inside the protective bag 33 reaches the set value, the protective bag 33 is then fully limited to the building steel structure from below the steel structure 2 to be hoisted. By realizing the lower limit function of the building steel structure, the falling phenomenon of the building steel structure during hoisting is effectively reduced. When the building steel structure needs to be removed from the hoisting device 1, the gas inside the protective bag 33 is fully emptied; In the lifting state, the electromagnetic suction block 30 fits the building steel structure and magnetically positions the building steel structure; By realizing the magnetic positioning, side clamp positioning and lower limit functions, the stability of the building steel structure during hoisting is effectively guaranteed.
