Description

Technical Field

[0001] The invention relates to an auxiliary dismantling device for an aluminum template bottom mold, belonging to the technical field of building construction auxiliary equipment. Background Art

[0002] With the gradual development of the construction industry, aluminum formwork is increasingly widely used in construction projects due to its light weight, easy production and reusability. During the construction of the concrete top formwork, the top formwork of the wall is usually fixed with an aluminum formwork, and then the concrete is poured. When the concrete strength meets the requirements of the specification, the aluminum formwork can be removed. During the removal of the aluminum formwork, due to the high height of the concrete top plate aluminum formwork, it is difficult to remove the concrete top plate aluminum formwork. In order to quickly remove the concrete top plate aluminum formwork, the construction site workers often do not stand on the stairs or trolleys as required to first remove the pins on the frame around the aluminum film and then remove the aluminum formwork piece by piece. Instead, they stand on the ground and use a crowbar to violently remove the concrete top plate aluminum formwork. The damaged aluminum film cannot be recycled and is easy to damage the concrete top plate structure. Summary of the invention

[0015] The reference numerals in the drawings of the specification include: wheel 1, trolley 2, groove 3, motor 4, rotating shaft 5, first cylinder 6, second cylinder 7, pressure sensor 8, slide slot 9, first switch 10, second switch 11. DETAILED DESCRIPTION

[0016] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Embodiment 1: An auxiliary removal device for an aluminum template bottom mold, such as Figure 1 As shown, the trolley 2 includes a wheel 1 at the lower end of the trolley 2, which is convenient for the trolley 2 to move. The upper end of the trolley 2 is provided with a groove 3, and a motor 4 is fixed inside the groove 3. The motor 4 is a servo motor, and the motor 4 can rotate forward and reverse. The motor 4 is electrically connected to an encoder, and the rotation angle of the motor 4 is controlled by the encoder; the output shaft of the motor 4 is arranged horizontally and backward, and a rotating shaft 5 with an axis arranged in a vertical direction is fixed on the output shaft of the motor 4. A first cylinder 6 with a telescopic end arranged vertically upward is fixed on the upper end of the rotating shaft 5, and two second cylinders 7 are fixed symmetrically on the telescopic end of the first cylinder 6, and the telescopic end of the second cylinder 7 is arranged in a horizontal direction. The rotation of the motor 4 can drive the first cylinder 6 and the second cylinder 7 to tilt and reset as a whole.

[0018] In this embodiment, a slide groove 9 inclined toward the lower left is provided on the left side of the trolley 2 .

[0019] In this embodiment, a first switch 10 with contacts facing upward is fixed on the top of the first cylinder 6, and the first switch 10 is electrically connected to the second cylinder 7. When the first switch 10 is pressed, the second cylinder 7 extends. A second switch 11 with contacts facing upward is fixed on the upper end of the shell of the first cylinder 6. During the contraction of the first cylinder 6, the second cylinder 7 can press the second switch 11. The second switch 11 is electrically connected to the second cylinder 7. When the second switch 11 is pressed, the second cylinder 7 contracts.

[0020] In this embodiment, a pressure sensor 8 is installed on the telescopic end of the second cylinder 7, and the pressure sensor 8 is electrically connected to a controller, and the controller is electrically connected to the second cylinder 7; the pressure value is set by the controller, and when the pressure sensor 8 is squeezed and the pressure value of the pressure sensor 8 reaches the set value, the controller controls the second cylinder 7 to stop extending.

[0021] The specific implementation process is as follows: The aluminum mold is rectangular and has a frame around the lower end. Two adjacent aluminum molds are connected by pins and the frame.

[0022] All pins on the aluminum formwork are manually removed in advance.

[0023] In the initial state, the first cylinder 6 is contracted and the second cylinder 7 is contracted. The trolley 2 moves to the right below the target aluminum template, and then the first cylinder 6 is extended until the first switch 10 is pressed, and then the first switch 10 controls the second cylinder 7 to extend through the controller. When the pressure value of the pressure sensor 8 reaches the set value, the controller controls the second cylinder 7 to stop extending, and the two second cylinders 7 are used to press the left and right frames below the aluminum template tightly. Next, the encoder is used to make the motor 4 alternately rotate forward and reverse 5° for multiple times and then reset. This process is intended to use the first cylinder 6 and the second cylinder 7 to make the aluminum formwork vibrate in the left and right directions, so as to facilitate the separation of the aluminum formwork from the concrete top plate. Then, the first cylinder 6 contracts, and the two second cylinders 7 cooperate to pull the aluminum template downward to realize the removal of the aluminum template; during the contraction of the first cylinder 6, when the second cylinder 7 presses the second switch 11, the second cylinder 7 contracts; Next, the encoder is used to make the motor 4 rotate forward, and the motor 4 drives the first cylinder 6 and the second cylinder 7 to tilt left as a whole, and the aluminum template automatically falls on the slide 9. The staff on the ground collects the disassembled aluminum template and places it in the designated position.

[0024] Then, the motor 4 is rotated in the reverse direction to reset the first cylinder 6 .

[0025] Repeat this process continuously to achieve automatic removal of the remaining aluminum formwork.

[0026] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
