Description

Technical Field

[0001] The present invention relates to the technical field of concrete exterior wall hanging plate construction, in particular to a large prefabricated concrete exterior wall hanging plate hoisting frame and a hoisting method. Background Art

[0002] When the precast concrete slab is transported to the construction site, it is usually placed horizontally. Before vertical hoisting, the precast concrete slab needs to be flipped over. However, the precast concrete slab is large in size and weight. During the flipping process, the edges and corners of the precast concrete slab are easily damaged by collision with other objects. Therefore, a hoisting conversion frame is needed to change the direction of the slab. When the conversion frame and the slab are hoisted from horizontal to vertical, the center of gravity of the conversion frame and the slab is continuously moved forward. When the conversion frame and the slab are about to be in the vertical position, the center of gravity of the conversion frame and the slab is shifted, thereby pulling the conversion frame and the slab downward suddenly and rapidly and contacting the ground, causing the conversion frame and the slab to shake violently from side to side, which can easily cause the conversion frame and the slab to tip downward and cause damage. Moreover, due to the large weight and volume of the slab, when the slab is placed on the conversion frame, there is a gap between the slab and the base of the conversion frame. When the slab is gradually in the vertical position, under the action of gravity, the slab moves downward on the side wall of the conversion frame and contacts the base, thereby causing damage to the edges and corners of the conversion frame.

[0003] Therefore, it is necessary to provide a new large-scale precast concrete exterior wall hanging panel hoisting frame and hoisting method to solve the above technical problems. Summary of the Invention

[0010] Preferably, the mounting plate, the second rubber pad and the side wall of the compression rod are all "L"-shaped structures, and the compression rod and the third connecting pipe are staggered.

[0011] Preferably, one end of the first fixing plug is a conical structure, the other end of the first fixing plug is a cylindrical structure, and the diameter of the first fixing plug is equal to the inner diameter of the second connecting pipe.

[0012] Preferably, the side wall of the fourth communicating tube is arc-shaped, and the sealing rod is located between two ends of the fourth communicating tube.

[0013] Preferably, a steel mesh is provided inside the concrete slab, and lifting pieces are symmetrically installed on the side walls of the concrete slab.

[0014] Preferably, a method for hoisting large precast concrete exterior wall panels comprises the following steps:

[0015] Step 1: transport the concrete slab to the hoisting site. When the concrete slab needs to be rotated from horizontal to vertical, place the concrete slab on the surfaces of the first support plate and the second support plate, and use the fixing mechanism and the limiting mechanism to fix the concrete slab to the side wall of the conversion frame. During the placement of the concrete slab, a certain distance exists between the concrete slab and the base. Open the valve and squeeze the pressure rod. The pressure rod drives the first sealing plate to move inside the first box and stretch the first spring. At the same time, the first sealing plate allows the hydraulic oil inside the first box to enter the interior of the second box through the third connecting pipe and the fourth connecting pipe. The hydraulic oil squeezes the second sealing plate, causing the second sealing plate, the sliding rod, the mounting plate and the second rubber pad to move inside the second box, so that the second rubber pad contacts the side wall of the concrete slab. Then close the valve to fix the second rubber pad.

[0016] The second step is to connect the lifting link with the lifting link, and the operation of the lifting link drives the conversion frame to pull up. At this time, the pulley under the second support plate slides on the ground, which facilitates the upward movement of the conversion frame and the concrete slab. As the conversion frame moves upward, the pulley under the first connecting rod connected to the base contacts the ground, and the pulley on one side of the second support plate falls off the ground. The vertical center of gravity of the conversion frame gradually moves forward, and the weight of the concrete slab is large, so the suspended end of the conversion frame is prone to sudden downward movement, which may cause the conversion frame to tip over. At this time, the pulley at one end of the support rod contacts the ground to prevent the conversion frame from moving downward suddenly. The worker holds the conversion frame, steps on the first lever to compress the second spring, and the rotation of the first lever pulls the steel cable to slide on the side wall of the fixed pulley. At the same time, the fixed pulley drives the first piston and the first fixed plug to move. The first fixed plug moves inside the second connecting pipe and gradually separates from the through hole. At the same time, the third spring is compressed, and the first fixed plug with a tapered end moves to the Directly below the through-hole, the through-hole is gradually opened, allowing the hydraulic oil in the interior of the fixed column to enter the interior of the first box through the water pipe, the through-hole and the first connecting pipe; under the action of the gravity of the conversion frame and the concrete slab, the support rod drives the second piston to move in the interior of the fixed column, and the second piston pushes the hydraulic oil in the interior of the fixed column into the interior of the water pipe; as the support rod enters the interior of the fixed column, the conversion frame is gradually and slowly brought into a vertical state; in the process of the conversion frame tending to the vertical state, when the conversion frame moves downward too quickly, the first lever is released, the second spring and the third spring extend to push the first lever and the first fixing plug to move, causing the first fixing plug to move in the direction of the third spring, reducing the distance between the first fixing plug and the through-hole, thereby slowing down the flow rate of the hydraulic oil in the through-hole, preventing the hydraulic oil in the fixed column from losing too quickly, thereby slowing down the movement speed of the fixing rod in the fixed column, causing the conversion frame to gradually and slowly be lowered into a vertical state;

[0017] Step 3: When the concrete slab gradually tends to a vertical state, the mounting plate and the second rubber pad provide support for the concrete slab to prevent the concrete slab from sliding downward on the side wall of the conversion frame and causing damage; when the support rod enters one end distance inside the fixing column, the fixing column drives the compression mechanism to move and opens the third connecting pipe. When the concrete slab moves downward, the concrete slab pushes the second rubber pad, the mounting plate, the sliding rod and the second sealing plate to move downward. The second sealing plate squeezes the hydraulic oil inside the second box into the interior of the first box through the third connecting pipe. The hydraulic oil inside the second box slows down the downward movement of the concrete slab, and the second rubber pad always wraps the bottom end of the concrete slab to prevent the concrete slab from being damaged during the sliding process; when the fixing ring contacts the side wall of the fixing column, the conversion frame and the concrete slab are in a vertical state.

[0018] Step 4: The worker climbs the ladder to the top of the concrete slab, connects the sling on the crane to the lifting member, and separates the limiting mechanism and the fixing mechanism from the concrete slab, and then the concrete slab can be vertically lifted.

[0019] Compared with related technologies, the large precast concrete exterior wall panel hoisting frame and hoisting method provided by the present invention have the following beneficial effects:

[0020] The present invention provides a large-scale precast concrete exterior wall hanging panel hoisting frame and a hoisting method. The operation of the crane drives the conversion frame to be pulled up. At this time, the pulley under the second support plate slides on the ground, which is convenient for the conversion frame and the concrete plate to move upward; as the conversion frame moves upward, the pulley under the first connecting rod connected to the base contacts the ground, and the pulley on one side of the second support plate falls off the ground; the vertical center of gravity of the conversion frame gradually moves forward, and the weight of the concrete plate is large, so the suspended end of the conversion frame is prone to sudden downward movement, which can easily cause the conversion frame to tilt. The first lever rotates to pull the steel cable, the first piston and the first fixed plug, and the first fixed plug with a conical end moves inside the second connecting pipe to gradually open the through hole, so that the hydraulic oil inside the fixed column passes through the water pipe, the through hole and the first connecting pipe into the interior of the first box; under the action of the gravity of the conversion frame and the concrete slab, the support rod drives the second The piston moves inside the fixed column, and the second piston pushes the hydraulic oil inside the fixed column into the inside of the water pipe; as the support rod enters the inside of the fixed column, the conversion frame gradually and slowly becomes vertical; by controlling the distance between the first fixing plug and the through hole, the speed at which the support rod enters the inside of the support column is adjusted; when the concrete slab gradually tends to be vertical, the mounting plate and the second rubber pad provide support for the concrete slab to prevent the concrete slab from sliding downward on the side wall of the conversion frame and causing damage; when the support rod enters one end distance inside the fixed column, the fixed column drives the compression mechanism to move and open the third connecting pipe. When the concrete slab moves downward, the concrete slab pushes the second rubber pad, the mounting plate, the sliding rod and the second sealing plate to move downward, and the second sealing plate squeezes the hydraulic oil inside the second box into the inside of the first box through the third connecting pipe. The hydraulic oil inside the second box slows down the downward movement of the concrete slab, and the second rubber pad always wraps the bottom end of the concrete slab to prevent damage to the concrete slab during sliding.

[0040] A steel mesh 71 is provided inside the concrete slab 7 to increase the strength of the interior of the concrete slab 7 , and lifting pieces 72 are symmetrically installed on the side walls of the concrete slab 7 to facilitate the connection of the slings with the lifting machine 72 and to facilitate lifting the concrete slab 7 upwards.

[0041] Preferably, a method for hoisting large precast concrete exterior wall panels comprises the following steps:

[0042] Step 1: transport the concrete slab 7 to the hoisting site. When the concrete slab 7 needs to be rotated from horizontal to vertical, place the concrete slab 7 on the surfaces of the first support frame 12 and the second support frame 13. One end of the concrete slab 7 contacts the side wall of the third rubber pad 64. Rotate the first fixing rod 51 and the second fixing rod 54 so that the first rubber pad 57 of the side wall of the extrusion plate 52, the second fixing rod 54 and the oblique rod 56 contacts the side wall of the concrete slab 7. Rotate the screw 43 so that the screw 43 rotates inside the connecting plate 41, so that the screw 43 pushes the fixing sleeve 42 to move, and the screw 43 and the fixing sleeve 42 are rotationally connected so that the fixing sleeve 42 does not rotate synchronously with the screw 43. The rotation of the screw 43 drives the fixing sleeve 42 to approach and squeeze the first fixing rod 51 and the second fixing rod 54, thereby the first fixing rod 51 and the second fixing rod 54, and then the pull rope 53 is wrapped around the side walls of the extrusion plate 52 and the second fixing rod 54; during the placement of the concrete slab 7, there is a certain distance between the concrete slab 7 and the base 11, and the valve 89 is opened to squeeze the pressure rod 211. The pressure rod 211 drives the first sealing plate 29 to move inside the first box 27 and stretch the first spring 210. At the same time, the first sealing plate 29 allows the hydraulic oil inside the first box 27 to enter the interior of the second box 64 through the third connecting pipe 66 and the fourth connecting pipe 88. The hydraulic oil squeezes the second sealing plate 65, so that the second sealing plate 65, the sliding rod 63, the mounting plate 61 and the second rubber pad 62 move inside the second box 64, so that the second rubber pad 62 contacts the side wall of the concrete slab 7, and then the valve 89 is closed to fix the second rubber pad 62;

[0043] Step 2: Use a crane to connect with the lifting ring 16, and the operation of the crane drives the conversion frame 1 to pull up. At this time, the pulley 21 under the second support plate 13 slides on the ground, which facilitates the upward movement of the conversion frame 1 and the concrete slab 7; as the conversion frame 1 moves upward, the pulley 21 under the first connecting rod 22 connected to the base 11 contacts the ground, and the pulley 21 on one side of the second support plate 13 falls off the ground; the vertical center of gravity of the conversion frame 1 gradually moves forward, and the weight of the concrete slab 7 is large, and the suspended end of the conversion frame 1 is prone to sudden The downward movement may easily cause the conversion frame 1 to fall over; at this time, the pulley 21 at one end of the support rod 23 contacts the ground to prevent the conversion frame 1 from moving downward suddenly; the worker holds the conversion frame 1 and steps on the first lever 31 to compress the second spring 35. The first lever 31 rotates and pulls the steel cable 33 to slide on the side wall of the fixed pulley 34. At the same time, the fixed pulley 34 drives the first piston 37 and the first fixed plug 310 to move. The first fixed plug 310 moves inside the second connecting pipe 311 and gradually separates from the through hole 39 while compressing the The third spring 38 and the first fixed plug 310 with a tapered end move to the right below the through hole 39, gradually opening the through hole 39, so that the hydraulic oil inside the fixed column 24 enters the interior of the first box body 27 through the water pipe 26, the through hole 39 and the first connecting pipe 36. The first piston 37 moves inside the first connecting pipe 36, and the first piston 37 seals the bottom end of the first connecting pipe 36 with a "T"-shaped side wall to prevent the hydraulic oil from leaking out of the interior of the first connecting pipe 36. Under the action of the gravity of the plate 7, the support rod 23 drives the second piston 212 to move inside the fixed column 24. The second piston 212 pushes the hydraulic oil inside the fixed column 24 into the water pipe 26 and the first box 27. The first sealing plate 29 moves upward inside the first box 27 to compress the first spring 210. The air at the top of the first box 27 is discharged through the vent pipe opened at the top of the first box 27. As the support rod 23 enters the interior of the fixed column 24, the conversion frame 1 gradually becomes vertical.When the conversion frame 1 moves downward too quickly during the process of being moved toward the vertical state, the first lever 31 is released, and the second spring 35 and the third spring 38 extend to push the first lever 31 and the first fixing plug 310 to move, so that the first fixing plug 310 moves in the direction along the third spring 38, reducing the distance between the first fixing plug 310 and the through hole 39, thereby slowing down the flow rate of the hydraulic oil in the through hole 39, preventing the hydraulic oil in the fixing column 24 from losing too quickly, thereby slowing down the movement speed of the fixing rod 23 in the fixing column 24, and causing the conversion frame 1 to gradually and slowly be lowered to the vertical state;

[0044] When the concrete slab 7 gradually tends to be vertical, the mounting plate 61 and the second rubber pad 62 provide support for the concrete slab 7 to prevent the concrete slab 7 from sliding downward on the side wall of the conversion frame 1 and causing damage; when the support rod 23 enters one end distance inside the fixing column 24, the support rod 23 drives the compression rod 81 to move upward. When the compression rod 81 moves, it drives the second lever 82 to rotate on the side wall of the limit plate 83. The rotation of the second lever 82 drives the pull rope 84 and the second fixing plug 86 to move inside the sealing rod 85, so that the second fixing plug 85 moves to lengthen the second spring 87, and at the same time, the second fixing plug 85 moves to lengthen the fourth spring 87 and separate from the third connecting pipe 66, so that the second connecting pipe 66 is connected through the sealing rod 85. When the concrete slab 7 moves downward on the side wall of the conversion frame 1 under the action of gravity, the concrete slab 7 pushes the second rubber pad 82 to rotate. The rubber pad 62, the mounting plate 61, the sliding rod 63 and the second sealing plate 65 move downward, and the second sealing plate 65 squeezes the hydraulic oil inside the second box body 64 into the interior of the first box body 27 through the third connecting pipe 66. The hydraulic oil inside the second box body 64 slows down the downward movement of the concrete slab 7. At this time, the hydraulic oil inside the fixing column 24 also enters the interior of the first box body 22 to squeeze the first sealing plate 29 and the first spring 210. The compression degree of the first spring 210 gradually increases, which increases the speed at which the hydraulic oil enters the interior of the first box body 22, preventing the hydraulic oil inside the second box body 64 from quickly entering the interior of the first box body 22, so that the second rubber pad 62 always wraps the concrete slab 7 and moves slowly downward, preventing the concrete slab 7 from being damaged during the downward sliding process; when the fixing ring 25 contacts the side wall of the fixing column 24, the conversion frame 1 and the concrete slab 7 are in a vertical state;

[0045] Step 4: The worker climbs the ladder 15 to the top of the concrete slab 7, connects the sling on the crane to the lifting member 72, and separates the limiting mechanism 4 and the fixing mechanism 5 from the concrete slab 7, so that the concrete slab 7 can be lifted vertically.

During the placement of the concrete slab (7), there is a certain distance between the concrete slab (7) and the base (11). Open the valve (89) and squeeze the pressure rod (211). The pressure rod (211) drives the first sealing plate (29) to be fixed in the first box ( 27) The internal movement stretches the first spring (210), and at the same time, the first sealing plate (29) allows the hydraulic oil inside the first box (27) to enter the interior of the second box (64) through the third connecting pipe (66) and the fourth connecting pipe (88), and the hydraulic oil squeezes the second sealing plate (65), so that the second sealing plate (65), the sliding rod (63), the mounting plate (61) and the second rubber pad (62) move inside the second box (64), so that the second rubber pad (62) contacts the side wall of the concrete slab (7), and then the valve (89) is closed to fix the second rubber pad (62); Step 2: Use a crane to connect with the lifting ring (16), and the operation of the crane drives the conversion frame (1) to pull up. At this time, the pulley (21) under the second support plate (13) slides on the ground, which facilitates the upward movement of the conversion frame (1) and the concrete slab (7); as the conversion frame (1) moves upward, the pulley (21) under the first connecting rod (22) connected to the base (11) contacts the ground, and the pulley (21) on one side of the second support plate (13) falls off from the ground; the vertical center of gravity of the conversion frame (1) gradually moves forward, and the concrete slab (7) is heavy, so the suspended end of the conversion frame (1) is prone to sudden downward movement, which can easily cause the conversion frame (1) to fall over; At this time, the pulley (21) at one end of the support rod (23) contacts the ground to prevent the conversion frame (1) from moving downward suddenly; the worker holds the conversion frame (1) and steps on the first lever (31) to compress the second spring (35).

The first fixed plug (310) with a tapered end moves to the through hole ( 39), gradually opening the through hole (39) so that the hydraulic oil inside the fixed column (24) enters the interior of the first box (27) through the water pipe (26), the through hole (39) and the first connecting pipe (36); under the action of the gravity of the conversion frame (1) and the concrete slab (7), the support rod (23) drives the second piston (212) to move inside the fixed column (24), and the second piston (212) pushes the hydraulic oil inside the fixed column (24) into the interior of the water pipe (26); as the support rod (23) enters the interior of the fixed column (24), the conversion frame (1) is gradually and slowly placed in a vertical state; as the conversion frame (1) tends to During the vertical state, when the conversion frame (1) moves downward too quickly, the first lever (31) is released, and the second spring (35) and the third spring (38) extend to push the first lever (31) and the first fixed plug (310) to move, so that the first fixed plug (310) moves in the direction along the third spring (38), reducing the distance between the first fixed plug (310) and the through hole (39), thereby slowing down the flow rate of the hydraulic oil in the through hole (39), preventing the hydraulic oil in the fixed column (24) from losing too quickly, thereby slowing down the movement speed of the fixed rod (23) in the fixed column (24), and causing the conversion frame (1) to gradually and slowly lower to the vertical state; Step 3: When the concrete slab (7) gradually tends to be vertical, the mounting plate (61) and the second rubber pad (62) provide support for the concrete slab (7) to prevent the concrete slab (7) from sliding downward on the side wall of the conversion frame (1) and causing damage; when the support rod (23) enters one end distance inside the fixing column (24), the fixing column (24) drives the compression mechanism (8) to move and opens the third connecting pipe (66).
