Then, the air pump 201a starts to fill the air storage tank 201b with high-pressure air. After the pressure in the air storage tank 201b reaches the required threshold, the interaction controller 202d controls the vacuum generator 202c to start to generate negative pressure in the buffer suction cup 104f to suck the wooden formwork. Then, the interaction controller 202d controls the solenoid valve 202b to start in a pulse manner in turn, spraying compressed gas between the wooden formwork and the concrete, using the expansion of the compressed air to separate the wooden formwork and the concrete. At the same time, starting in a pulse manner can prevent multiple solenoid valves 202b from starting simultaneously, resulting in too much decrease in the pressure of the sprayed compressed gas and not meeting the force required to peel off the wooden formwork. Then, the first servo motor 102c starts in the reverse direction to drive the threaded drill rod 105c to move downward to remove and recycle the peeled wooden formwork.

[0055] In summary, the beneficial effect of the present invention is that by drilling the hollow threaded drill rod between the wooden formwork and the concrete, and then using the air injection hole at the head of the threaded drill rod to spray compressed air, which acts between the wooden formwork and the concrete, and using the principle of rapid expansion of the compressed air to separate the wooden formwork and the concrete, thereby realizing the rapid and efficient peeling of the wooden formwork. At the same time, the threaded drill rod drilled into the wooden formwork can also fix the wooden formwork to be pre-dismantled to prevent the wooden formwork from flying out when the compressed gas is sprayed, and can also recover the peeled wooden formwork. The buffer suction cup can generate negative pressure under the action of the vacuum generator to firmly suck the wooden formwork, prevent the wooden formwork from shaking, and can also provide support for the wooden formwork when the threaded drill rod detaches from the wooden formwork to prevent the wooden formwork from falling.

[0068] The interaction controller controls the lifting rod to lower and retract the formwork.

[0069] It should be noted that the formwork stripping step of the building formwork demolition device is simple and clear. First, drill the threaded drill rod 105c in the detachment component 105 into the formwork, so that the air injection holes 105i at the head of the threaded drill rod 105c are between the formwork and the concrete, and then charge compressed gas.

[0083] Furthermore, the present invention further proposes a method for using a building formwork removal device, including a building formwork removal device, which comprises the following steps:

[0084] Move the building formwork removal device to the lower part of the formwork to be removed, and align it with the formwork to be removed through the control component;

[0085] Drill the threaded drill rod between the formwork and the concrete, and use the principle of compressed air expansion to peel off and remove the formwork.

[0086] Furthermore, moving the building formwork removal device to the lower part of the formwork to be removed and aligning it with the formwork to be removed through the control component includes:

[0087] Input corresponding data parameters in the interaction controller;

[0088] The interaction controller controls the lifting component and the steering component to cooperate with each other to drive the threaded drill rod to press against the formwork to be removed.

[0089] Furthermore, drilling the threaded drill rod between the formwork and the concrete and using the principle of compressed air expansion to peel off and remove the formwork includes:

[0090] The interaction controller controls the third servo motor to start, drives the threaded drill rod to rotate and drill into the formwork, so that the air injection holes are between the formwork and the concrete;

[0091] The interaction controller controls the air pump to start and fill the air storage tank with compressed air;

[0092] The interaction controller controls the vacuum generator to start to generate negative pressure in the buffer suction cup to suck the formwork and prevent the formwork from shaking;

[0093] The interaction controller controls the solenoid valve to start in a pulse manner to fill the compressed air between the formwork and the concrete through the air injection holes, and peel off the formwork;

[0094] The interaction controller controls the lifting rod to lower and retract the formwork.

[0095] It should be noted that the steps of stripping the wooden formwork of the building wooden formwork removing device are simple and clear. First, the threaded drill rod 105c in the separating component 105 is drilled into the wooden formwork, so that the air jet hole 105i at the head of the threaded drill rod 105c is located between the wooden formwork and the concrete. Then, compressed gas is filled, and the adhered wooden formwork is stripped from the concrete by using the mechanism of the rapid expansion of the compressed gas. Among them, the buffer suction cup 104f can suck and fix the wooden formwork by using negative pressure, and then the lifting rod 102i descends to remove the stripped wooden formwork, which is convenient for workers to recycle.

[0096] During use, the first servo motor 102c in the lifting component is started, so as to drive the C-shaped steering seat 103a fixed on the lifting rod 102i to rise. At the same time, the second servo motor 103b on the C-shaped steering seat 103a is started, so as to drive the buffer suction cup 104f in the buffer component 104 and the threaded drill rod 105c in the separating component to be aligned and pressed against the wooden formwork to be removed. At the same time, the third servo motor 105e drives the threaded drill rod 105c to rotate, so that the threaded drill rod 105c is drilled into the wooden formwork under the combined action of the pressure provided by the lifting rod 102i and the rotational force provided by the third servo motor 105e, and at the same time, it is ensured that the air jet hole 105i at the top of the threaded drill rod 105c is located between the wooden formwork and the concrete. Then, the air pump 201a is started to fill high-pressure air into the air storage tank 201b. After the pressure in the air storage tank 201b reaches the required threshold, the interaction controller 202d controls the vacuum generator 202c to start to generate negative pressure in the buffer suction cup 104f to suck and fix the wooden formwork. Then, the interaction controller 202d controls the solenoid valve 202b to be started in a pulsed manner in turn, and the compressed gas is sprayed between the wooden formwork and the concrete, and the wooden formwork and the concrete are separated by using the expansion of the compressed air. At the same time, starting in a pulsed manner can prevent the simultaneous start of multiple solenoid valves 202b, resulting in too much drop in the pressure of the ejected compressed gas and not meeting the force required to strip the wooden formwork. Then, the first servo motor 102c is started in the reverse direction to drive the threaded drill rod 105c to move downward to remove and recycle the stripped wooden formwork.

[0097] In summary, the beneficial effects of the present invention are as follows: by drilling the hollow threaded drill rod between the wooden formwork and the concrete, and then spraying compressed air through the air jet hole at the head of the threaded drill rod, acting between the wooden formwork and the concrete, and using the principle of the rapid expansion of the compressed air to strip the wooden formwork and the concrete, so as to realize the rapid and efficient stripping of the wooden formwork. At the same time, the threaded drill rod drilled into the wooden formwork can also fix the wooden formwork to be disassembled to prevent the wooden formwork from flying out when the compressed gas is sprayed, and can also recover the stripped wooden formwork. The buffer suction cup can generate negative pressure under the action of the vacuum generator to firmly suck and fix the wooden formwork to prevent the wooden formwork from shaking, and can also provide support for the wooden formwork when the threaded drill rod is separated from the wooden formwork to prevent the wooden formwork from falling.
