The output shaft of the driving motor 34 is connected to a driving screw 35. The driving screw 35 is rotatably installed in the boom 3. A screw nut 36 is fixedly installed in the pull rod 31, and the driving screw 35 is rotatably connected to the screw nut 36. When the driving motor 34 rotates, the driving screw 35 rotates accordingly, and then the pull rod 31 can be driven to move up and down in the boom 3 through the screw nut 36 to control the lifting and lowering of the support plate 32.

[0020] The wheel set 11 is in rolling contact with the surface of the telescopic arm 2, and the wheel set 21 is in sliding contact with the inner wall of the lifting frame 1. Through the arrangement of the wheel set 11 and the wheel set 21, the friction force of the telescopic arm 2 when it is extended and retracted in the lifting frame 1 can be greatly reduced, making the extension and retraction smooth and improving work efficiency.

[0021] A support platform 300 is fixedly provided in the boom 3, a plane bearing 301 is installed on the support platform 300, a pressure plate 302 is fixedly installed on the driving screw 35, and the pressure plate 302 presses on the plane bearing 301.

[0022] A buffer pad 1 310 is provided at the bottom of the pull rod 31 near the supporting plate 32, and a buffer pad 2 330 is provided at the bottom of the upper limit plate 33. Pressure sensors are provided in the buffer pad 1 310 and the buffer pad 2 330, and the pressure sensors are used to determine whether the template is clamped in place.

[0023] The structure of the driving device 4 includes a driving motor 41, and a driving bevel gear 42 is installed on the driving shaft of the driving motor 41. The driving bevel gear 42 is respectively meshed with two driven bevel gears 43. The driven bevel gear 43 is fixedly connected with a transmission shaft 44. A driving bevel gear 45 is provided at one end of the transmission shaft 44 away from the driven bevel gear 43. The driving bevel gear 45 is meshed with the driven bevel gear 46. A winding drum 140 is rotatably installed in the winding drum cavity 14. The rotating shaft of the driven bevel gear 46 is fixedly connected to the rotating shaft of the winding drum 140.

[0024] The telescopic arm 2 has a slot below for the steel wire rope 47 located below to pass through. The transmission structure in the driving device 4 is wrapped with a corresponding transmission protection cover. The driving device 4 is provided with four groups on the lifting frame 1. The transmission structure in each driving device 4 is provided with two completely symmetrical upper and lower groups. When the driving device 4 drives the telescopic arm 2 to move, the upper and lower transmission structures move in opposite directions; when the driving motor 2 41 rotates, the driving bevel gear 1 42 rotates, and the driving bevel gear 1 42 simultaneously drives the upper and lower driven bevel gears 1 43 to rotate in the opposite direction, thereby causing the upper and lower transmission shafts 44 to rotate in the opposite direction, and then driving the upper and lower winding discs 140 to rotate through the driving bevel gear 2 45 and the driven bevel gear 2 46, thereby controlling the extension and retraction of the telescopic arm 2.

[0025] A reinforcement member 51 is provided in the middle of the lifting frame 1. The arrangement of the reinforcement member 51 can ensure the overall strength of the lifting frame 1 and make it work stably.

[0026] A second reinforcing member 52 is provided between the support plate 32 and the pull rod 31. The provision of the second reinforcing member 52 can improve the stability and pressure bearing capacity of the support plate 32.

[0027] A reinforcement member 3 53 is provided between the upper limit plate 33 and the boom 3. The provision of the reinforcement member 3 53 can improve the stability and pressure bearing capacity of the upper limit plate 33.

[0028] The device is also connected to a control box through a wire. The control box is a control device based on a single-chip microprocessor, which can control the operation of the drive motor 1 34, the drive motor 2 41 and other components in the device. The control box can obtain the parameters of the pressure sensor set in the buffer pad 1 310 and the buffer pad 2 330, and indicate whether the template is clamped in place through the pressure sensor. The device is remotely controlled through the control box, which is easy to operate and improves work efficiency and safety.

[0029] When the device is in use, a hoisting wire rope is installed on the crane hook, and the hoisting wire rope passes through the lifting ring 13 to lift the device, connect the power supply and control wires, and lift the device above the template. The control box controls the telescopic arm 2 to extend and the pull rod 31 to descend, and the device is slowly lowered to the template surface. The telescopic arm 2 is retracted to an appropriate distance so that the support plate 32 enters under the template, and the pull rod 31 is raised until it touches the bottom of the template. The telescopic arm 2 is retracted again until the control box obtains the pressure information of the pressure sensor in the buffer pad 1 310 and stops automatically or manually. The pull rod 31 rises again, and the support plate 32 gradually lifts the template until the template contacts the buffer pad 2 330. The control box obtains the pressure sensor information in the buffer pad 2 330 and stops automatically or manually. At this point, the clamping work of the template can be completed and the hoisting can be carried out. When lifting some formwork with uneven weight distribution, the center of gravity of the formwork can be adjusted to the longitudinal center axis of the lifting frame 1 by independently controlling the extension length of each telescopic arm 2 to make the lifting stable. Each pull rod 31 can also be controlled independently, so formwork with different edge thicknesses can be lifted. It has strong applicability and is easy to use.

[0030] By adopting this device, compared with the most common wire rope binding hoisting, the hoisting efficiency is increased by more than 40%, and the installation qualification rate of complex formwork with unequal edge thickness or uneven center of gravity distribution reaches 98.6%, which can significantly improve the hoisting efficiency of water conservancy project formwork.
