Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to a hydraulic balance hoisting platform and a construction method thereof. Background Art

[0002] As Figure 1 shown, during the installation process of the steel platform formwork system, the external hanging frame unit 1 is a sliding device bolted to the lower flange of the top platform beam 2 of the steel platform. The conventional installation process of the external hanging frame unit 1 is as follows: First, use the tower crane 4 to lift the assembled external hanging frame unit 1 from the ground and turn it upright, and hoist the external hanging frame unit 1 to the outside of the top platform beam 2 of the steel platform. Then, use multiple groups of gantry frames 3 erected above the top platform beam 2 in cooperation with the winch to lift the external hanging frame unit 1 from the outside of the top platform beam 2 to below the gantry frame 3. There is a force conversion process between the tower crane 4 and the gantry frame 3, resulting in the phenomenon of high-altitude oblique hoisting of the external hanging frame unit 1, and the construction safety is poor. Moreover, after each external hanging frame unit 1 is installed, the gantry frame 3 and the winch need to be moved to the next installation position, and the gantry frame 3 needs to be frequently disassembled and moved, with cumbersome operations, reducing the construction efficiency. Summary of the Invention

[0003] Aiming at the problems of low construction efficiency and poor safety in the existing method of installing the external hanging frame unit by using the gantry frame installed on the steel platform in cooperation with the tower crane. The purpose of the present invention is to provide a hydraulic balance hoisting platform and a construction method thereof.

[0004] The technical solution adopted by the present invention to solve its technical problems is: A hydraulic balance hoisting platform, characterized in that it includes: a first frame platform, a second frame platform, a hydraulic cylinder, a counterweight, and a leveling sensor control group. The first frame platform is connected to the top of the second frame platform. The hydraulic cylinder and the counterweight are arranged along the axis of the first frame platform. One end of the hydraulic cylinder is connected to one side of the first frame platform, the counterweight is snap-connected to the other side of the first frame platform, the other end of the hydraulic cylinder is connected to the counterweight, the tower crane is connected to the side of the first frame platform away from the counterweight, the external hanging frame unit is on the side of the second frame platform away from the counterweight, and the leveling sensor control group is arranged on the first frame unit and is signal-connected to the hydraulic cylinder.

[0005] The hydraulic balance lifting platform of the present invention comprises a double-layer frame structure composed of a first frame platform and a second frame platform which are arranged up and down and connected. The hydraulic cylinder and the counterweight are arranged along the axis of the first frame platform and connected. The other end of the hydraulic cylinder is connected to one side of the first frame platform, and the counterweight is snap-connected to the other side of the first frame platform. The other end of the hydraulic cylinder is connected to the counterweight. The tower crane is connected to the first frame platform and horizontally lifts it. The external hanging frame unit is suspended on the side of the second frame platform far from the counterweight. In the case of the center of gravity of the lifting platform shifting, the leveling sensor control group sends a signal to control the hydraulic cylinder to extend, pushing the counterweight to translate along the first frame platform in the direction away from the external hanging frame unit, so that the lifting platform can maintain overall balance when lifting the external hanging frame unit. Then, the lifting platform horizontally extends under the top platform beam of the steel platform, and installs the external hanging frame unit in place, without additionally setting up a gantry and a hoist above the platform beam and completing the force conversion with the tower crane, avoiding the alternating operation of lifting equipment at high altitude. Moreover, since there is no need to repeatedly disassemble and assemble the gantry and the hoist at high altitude, not only the lifting construction efficiency is improved, but also the construction safety is ensured. This hydraulic balance lifting platform is applicable to the installation and removal construction of internal and external hanging frame units of all steel platform formwork systems.

[0006] Further, the leveling sensor control group includes an inclination sensor, an adjustment controller, a communication module, a terminal device and a power supply component which are connected. The inclination sensor is used to monitor the inclination angle of the lifting platform in real time and feedback it to the adjustment controller. The leveling controller receives the signal from the inclination sensor and controls the telescopic movement of the hydraulic cylinder for leveling. The communication module is used to transmit data signals to the terminal device, and the power supply component is used to supply power to the leveling controller, the inclination sensor and the communication module.

[0007] Further, the terminal device at least includes a display and a remote controller which are signal-connected to the adjustment controller.

[0008] Further, the first frame platform includes a frame body, a pair of guide rails and a plurality of feet. The frame body is formed by connecting two horizontal bars which are parallel and spaced apart, and a plurality of vertical bars which are spaced between the two horizontal bars. The horizontal bar in the middle divides the frame body into a fixed frame and a balance frame. The plurality of feet are respectively connected to the bottoms of the corners of the fixed frame and the balance frame. The hydraulic cylinder is arranged along the axis of the fixed frame. A pair of guide rails are symmetrically arranged on both sides of the balance frame along its axis, and the two ends of the guide rails are respectively connected to the middle parts of the feet on both sides. The sliders at both ends of the counterweight are respectively snap-connected to the guide rails and can slide along the guide rails. One lifting lug is provided at each of the four corners of the fixed frame of the first frame platform.

[0009] Furthermore, the first frame platform further includes a connecting rod, which is vertically arranged and connected between the first frame platform and the second frame platform, and the end of the hydraulic cylinder is connected to the middle of the connecting rod.

[0010] Furthermore, the first frame platform further includes a hydraulic pump station and a support frame. The support frame is connected inside the fixed frame body. The leveling sensor control group and the hydraulic pump station are fixed on the top of the support frame, and the hydraulic pump station is respectively signal-connected to the leveling sensor control group and the hydraulic cylinder.

[0011] Furthermore, the first frame platform further includes a horizontal sensor, which is connected to the top of the support frame.

[0012] Furthermore, the second frame platform is a frame structure formed by two parallel and spaced cross beams and multiple longitudinal beams spaced between the two cross beams. The positions of the cross beams and longitudinal beams correspond to the positions of the transverse members and longitudinal members of the first frame platform. One lifting lug two is respectively provided at the bottom of the ends of the two cross beams away from the counterweight.

[0013] In addition, the present invention also provides a construction method for a hydraulic balance lifting platform, and the steps are as follows: S1: When the hydraulic cylinders of the hydraulic balance lifting platform are in the initial state, connect the steel wire ropes of the tower crane to multiple lifting points of the first frame platform, and the tower crane horizontally lifts the hydraulic balance lifting platform; the external hanging frame unit is suspended by the steel wire rope at the lifting point at the end of the second frame platform. S2: The leveling sensor control group monitors the inclination angle of the lifting platform in real time, and the leveling sensor control group sends a signal to control the hydraulic cylinder to extend, pushing the counterweight to translate along the guide rail of the first frame platform in the direction away from the external hanging frame unit until the hydraulic balance lifting platform returns to the horizontal state. The tower crane hoists the external hanging frame unit to the lower part of the top platform beam of the steel platform. The lifting platform drives the external hanging frame unit to extend into the lower part of the top platform beam of the steel platform. After the external hanging frame unit is in place, it is bolted to the sliding device at the bottom of the top platform beam.

[0014] For the construction method of the hydraulic balance lifting platform of the present invention, firstly, the tower crane horizontally lifts the hydraulic balance lifting platform, hoists the external hanging frame unit suspended at the end of the second frame platform, and the leveling sensor control group controls the hydraulic cylinder to extend, pushing the counterweight to translate along the guide rail of the first frame platform in the direction away from the external hanging frame unit until the hydraulic balance lifting platform returns to the horizontal state. After the tower crane hoists the external hanging frame unit to the lower part of the top platform beam of the steel platform, the external hanging frame unit extends into the lower part of the platform beam along with the lifting platform and is bolted to the sliding device at the bottom of the platform beam; this construction method does not require a gantry and a winch to be set above the platform beam and complete the force conversion with the tower crane, avoiding the alternating operation of lifting equipment at high altitude, and does not require the repeated disassembly and assembly of the gantry and winch at high altitude, which not only improves the lifting construction efficiency but also ensures the construction safety.

[0015] Further, the step S1 further includes: before hoisting the hydraulic balance hoisting platform, first judge whether the hydraulic balance hoisting platform is in a horizontal state according to the real-time monitoring data of the horizontal sensor installed on the first frame platform. If it is not in a horizontal state, adjust the level of the hydraulic balance hoisting platform. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for the purpose of facilitating and clearly assisting in explaining the purpose of the embodiments of the present invention. For the sake of narrative convenience, the "upper" and "lower" described below are in the same direction as the upper and lower of the accompanying drawings, but this cannot be a limitation to the technical solution of the present invention.

[0019] This embodiment takes the hoisting construction of the external hanging frame unit 1 during the installation process of the steel platform formwork system as an example. The following combines Figures 2 to 4The hydraulic balance hoisting platform 100 of this embodiment has a width of approximately 2000 mm, a length of approximately 5500 mm, and a height of approximately 500 mm. It includes: a first frame platform, a second frame platform, a hydraulic cylinder 15, a counterweight 14, and a leveling sensor control group 24. The first frame platform is connected to the top of the second frame platform to form a double-layer frame structure. The hydraulic cylinder 15 and the counterweight 14 are arranged along the axis of the first frame platform. One end of the hydraulic cylinder 15 is connected to one side of the first frame platform, and the counterweight 14 is snap-connected to the other side of the first frame platform. The other end of the hydraulic cylinder 15 is connected to the counterweight 14. The side of the first frame platform away from the counterweight 14 can be connected to the hook of the tower crane. The external hanging frame unit 1 can be suspended on the side of the second frame platform away from the counterweight 14. The leveling sensor control group 24 is arranged on the first frame unit and is signal-connected to the hydraulic cylinder 15. In this embodiment, the stroke of the hydraulic cylinder 15 needs to match the sliding distance of the counterweight 14.

[0020] The hydraulic balance hoisting platform 100 of the present invention includes a double-layer frame structure composed of a first frame platform and a second frame platform that are arranged up and down and connected. The hydraulic cylinder 15 and the counterweight 14 are arranged along the axis of the first frame platform and connected. The other end of the hydraulic cylinder 15 is connected to one side of the first frame platform, and the counterweight 14 is snap-connected to the other side of the first frame platform. The other end of the hydraulic cylinder 15 is connected to the counterweight 14. The tower crane is connected to the first frame platform and horizontally hoists it. The external hanging frame unit 1 is suspended on the side of the second frame platform away from the counterweight 14. In the case of the center of gravity of the hoisting platform shifting, the leveling sensor control group 24 sends a signal to control the hydraulic cylinder 15 to extend, pushing the counterweight 14 to translate along the first frame platform in the direction away from the external hanging frame unit 1, so that the hoisting platform can maintain overall balance in the state of suspending the external hanging frame unit 1. Then, the hoisting platform horizontally extends under the top platform beam 2 of the steel platform, and installs the external hanging frame unit 1 in place, without additionally setting up a gantry 3 and a winch above the platform beam 2 and completing the force conversion with the tower crane, avoiding the alternating operation of hoisting equipment at high altitude. Moreover, since there is no need to repeatedly disassemble and assemble the gantry 3 and the winch at high altitude, not only the hoisting construction efficiency is improved, but also the construction safety is guaranteed. The hydraulic balance hoisting platform 100 is applicable to the installation and removal construction of the internal and external hanging frame units 1 of all steel platform formwork systems.

[0021] The leveling sensor control group 24 includes an inclination sensor, an adjustment controller, a communication module, a terminal device, and a power supply component connected to each other. The inclination sensor is used to monitor the inclination angle of the hoisting platform in real time, provide high-precision angle data and feedback it to the adjustment controller. The leveling controller receives the signal from the inclination sensor and controls the telescopic movement of the hydraulic cylinder 15 for leveling according to a preset algorithm. The communication module is used to transmit data signals to the terminal device. The power supply component is used to supply power to the leveling controller, the inclination sensor, and the communication module. The leveling sensor control group 24 drives the telescopic movement of the hydraulic cylinder 15 according to the horizontal monitoring data of the hoisting platform, so that the hoisting platform with the external hanging frame unit 1 automatically returns to the horizontal state.

[0022] The terminal device at least includes a display and a remote controller that are signal-connected to the adjustment controller. The display can display the leveling data of the hoisting platform in real time and intuitively. Construction workers can send instructions to the adjustment controller through the remote controller, so as to realize the one-key leveling or automatic leveling function.

[0023] As Figure 2 and Figure 3 As shown, the first frame platform includes a frame body, a pair of guide rails 17, and multiple support feet 16. The frame body is formed by connecting two horizontal bars 11 arranged in parallel and at intervals, and three vertical bars 12 arranged at intervals between the two horizontal bars 11. The middle horizontal bar 11 divides the frame body into a fixed frame and a balance frame. Multiple support feet 16 are respectively connected to the bottoms of the corners of the fixed frame and the balance frame. The hydraulic cylinder 15 is arranged along the axis of the fixed frame. A pair of guide rails 17 are symmetrically arranged on both sides along the axis of the balance frame, and both ends of the guide rails 17 are respectively connected to the middle parts of the two side support feet 16. The sliders at both ends of the counterweight 14 are respectively buckled on the guide rails 17 and can slide along the guide rails 17, reducing the friction between the contact surfaces of the counterweight 14 and the guide rails 17. In this embodiment, both the horizontal bar 11 and the vertical bar 12 are made of square steel pipes. The hydraulic cylinder 15 and the counterweight 14 with long-stroke double-acting are arranged along the axis of the double-layer frame structure, which can efficiently utilize the limited hoisting space and ensure the stability of the hoisting platform.

[0024] As Figure 2 As shown, one lifting lug 20 is respectively provided at each of the four corner parts of the fixed frame of the first frame platform, serving as the lifting point of the tower crane steel wire rope, which is convenient for the tower crane to horizontally hoist the hoisting platform.

[0025] Limit blocks are respectively installed at both ends of the guide rail 17 to prevent the counterweight 14 from tilting to one side when being pushed by the hydraulic cylinder 15, resulting in imbalance.

[0026] As Figure 2As shown, the first frame platform further includes a connecting rod 18. The connecting rod 18 is vertically arranged and connected between the longitudinal rod 12 of the first frame platform and the longitudinal beam 32 of the second frame platform. The end of the hydraulic cylinder 15 is connected to the middle of the connecting rod 18, so that the hydraulic cylinder 15 can be stably connected to the hoisting platform.

[0027] As Figure 2 shown, the first frame platform further includes a hydraulic pump station 21 and a support frame 19. The support frame 19 is connected within the fixed frame. The leveling sensor control group 24 and the hydraulic pump station 21 are fixed to the top of the support frame 19, and the hydraulic pump station 21 is respectively in signal connection with the leveling sensor control group 24 and the hydraulic cylinder 15. In this embodiment, the support frame 19 is formed by connecting a plurality of rods arranged vertically and horizontally, and the support frame 19 is welded to the fixed frame to provide stable support for the installation of the hydraulic pump station 21 and other monitoring instruments.

[0028] As Figure 2 shown, the first frame platform further includes a horizontal sensor 25. The horizontal sensor 25 is connected to the top of the support frame 19 and is used to monitor the angle change of the hoisting platform before the hoisting platform is lifted. The horizontal sensor 25 in this embodiment is preferably a high-precision electronic horizontal sensor 25.

[0029] Please continue to refer to Figure 2 and Figure 3 , the second frame platform is a frame structure formed by connecting two parallel and spaced cross beams 31 and three longitudinal beams 32 spaced between the two cross beams 31, and the positions of the cross beams 31 and the longitudinal beams 32 correspond to the positions of the transverse rods 11 and the longitudinal rods 12 of the first frame platform. A lifting lug two 35 is respectively provided at the bottom of one end of the two cross beams 31 away from the counterweight 14 as the lifting point of the external hanging frame unit 1. In this embodiment, the cross beams 31 and the longitudinal beams 32 are made of I-beams.

[0030] Combined with Figures 5 to 7 to illustrate the construction method of the hydraulic balance hoisting platform of the present invention, the steps are as follows: S1: As Figure 5 shown, when the hydraulic cylinder 15 of the hydraulic balance hoisting platform 100 is in the initial state, that is, the piston rod of the hydraulic cylinder 15 contracts, connect the steel wire rope of the tower crane with multiple lifting points of the first frame platform, and the tower crane horizontally lifts the hydraulic balance hoisting platform 100; as Figure 6 shown, the external hanging frame unit 1 is suspended by a steel wire rope at the lifting point at the end of the second frame platform. When the external hanging frame unit 1 is turned over and vertically lifted, the center of gravity is biased towards the fixed frame side of the first frame platform; S2: As Figure 7As shown, the leveling sensor control group 24 monitors the tilt angle of the hoisting platform in real time. The leveling sensor control group 24 sends a signal to control the hydraulic cylinder 15 to extend, pushing the counterweight 14 to translate along the guide rail 17 of the first frame platform away from the external hanging frame unit 1 until the hydraulic balance hoisting platform 100 resumes a horizontal state. After the tower crane 4 hoists the external hanging frame unit 1 to the lower part of the top platform beam 2 of the steel platform, the hoisting platform can drive the external hanging frame unit 1 to directly extend under the top platform beam 2 of the steel platform. After the external hanging frame unit 1 is in place, it is bolted to the sliding device at the bottom of the top platform beam 2.

[0031] For the construction method of the hydraulic balance hoisting platform of the present invention, first, the tower crane horizontally hoists the hydraulic balance hoisting platform 100 and hoists the external hanging frame unit 1 suspended at the end of the second frame platform. The leveling sensor control group 24 controls the hydraulic cylinder 15 to extend, pushing the counterweight 14 to translate along the guide rail 17 of the first frame platform away from the external hanging frame unit 1 until the hydraulic balance hoisting platform 100 resumes a horizontal state. After the tower crane 4 hoists the external hanging frame unit 1 to the lower part of the top platform beam 2 of the steel platform, the external hanging frame unit 1 extends under the platform beam 2 with the hoisting platform and is bolted to the sliding device at the bottom of the platform beam 2. This construction method does not require setting up a gantry 3 and a winch above the platform beam 2 and completing the force transfer with the tower crane, avoiding the alternating operation of hoisting equipment at high altitude, and there is no need to repeatedly disassemble and assemble the gantry 3 and the winch at high altitude, which not only improves the hoisting construction efficiency but also ensures the construction safety.

[0032] The step S1 further includes: before hoisting the hydraulic balance hoisting platform 100, first, according to the real-time monitoring data of the level sensor 25 installed on the first frame platform, judge whether the hydraulic balance hoisting platform 100 is in a horizontal state. If it is not in a horizontal state, adjust the level of the hydraulic balance hoisting platform 100 until the horizontal angle monitored by the level sensor 25 is 0°. Using the level sensor 25 to monitor the initial horizontal state of the hydraulic balance hoisting platform 100 can ensure the stability and safety of the subsequent hoisting construction of the external hanging frame unit 1.

[0033] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the art of the present invention based on the above disclosure fall within the scope of the claims.
