Description

Technical Field

[0001] This utility model relates to the field of building construction and dismantling technology, and in particular to an automatic formwork dismantling device for building construction. Background Technology

[0002] In the field of construction, formwork plays a crucial role as a temporary support structure. It is primarily used for concrete pouring and shaping, ensuring that the concrete solidifies according to the design requirements in terms of shape and size, thereby guaranteeing the appearance quality and dimensional accuracy of the concrete structure. The use of formwork is like creating a precise "mold" for the concrete, within which it is shaped and reaches the required strength. However, once the concrete has reached a certain strength, the formwork needs to be removed to allow for subsequent construction work.

[0003] In current construction, traditional formwork removal methods mainly rely on manual operation. Dismantling personnel need to work at heights, using simple tools such as crowbars to pry open the gaps between the concrete and the formwork, gradually loosening the formwork until it eventually falls off.

[0004] This dismantling method is not only inefficient, but also poses a great safety hazard. With the popularization of automation in various industries, the dismantling method of building formwork also needs to be improved. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-4 An embodiment of this utility model provides an automatic template dismantling device for building construction, comprising a cylinder 6, a base 1 fixedly mounted at the output end of the cylinder 6, a motor 4 fixedly mounted at the top of the base 1, a connecting rod 14 fixedly mounted at the output end of the motor 4, a suction cup 2 slidably connected to the outer wall of the connecting rod 14, a retaining sleeve 13 fixedly connected to the upper end of the connecting rod 14, a sliding rod 23 fixedly connected to the top of the retaining sleeve 13, a sliding cylinder 11 slidably connected to the outer wall of the sliding rod 23, a drill bit 3 fixedly connected to the top of the sliding cylinder 11, a retaining sleeve 12 provided on the outer wall of the sliding cylinder 11, a secondary umbrella rib 18 rotatably connected to the outer wall of the retaining sleeve 12, a main umbrella rib 19 rotatably connected to the outer wall of the retaining sleeve 13, the lower end of the secondary umbrella rib 18 rotatably connected to the main umbrella rib 19, a barb 20 fixedly connected to the upper end of the main umbrella rib 19, a locking device 22 provided on the sliding rod 23, and a locking hole 21 opened on the outer wall of the sliding cylinder 11.

[0025] In this embodiment, Figure 1The orientation is front, back, left, and right. There are four motors 4. The extension movement of the output end of the cylinder 6 drives the base 1 to rise until the drill bit 3 contacts the template. Driven by the output end of the motor 4, the drill bit 3 drives the drill bit to drill through the template and abut against the concrete layer. The locking device 22 releases the lock on the slide cylinder 11, and the output end of the cylinder 6 continues to extend. Through the sliding connection between the slide cylinder 11 and the slide rod 23, the slide rod 23 continues to move upward, which in turn causes the main umbrella rib 19, which is rotatably connected to the clamp 13, to move upward. Through the rotatable connection between the clamp 12 and the auxiliary umbrella rib 18, and the rotatable connection between the main umbrella rib 19 and the auxiliary umbrella rib 18, the top of the main umbrella rib 19, which follows the drill bit 3 and abuts against the concrete layer, gradually opens outward, so that the barb 20 slides into the gap between the template and the concrete and opens the template and the concrete apart. Through the retraction of the output end of the cylinder 6 and the downward movement of the upper end of the main umbrella rib 19 that passes through the template, the template falls onto the suction cup 2, thereby improving the efficiency of dismantling the building template.

[0026] Reference Figure 1 A rotating joint 5 is fixedly connected to the bottom center of the base 1. A joint rod 10 is rotatably connected to the inner side wall of the rotating joint 5. The bottom of the joint rod 10 is fixedly set on the output end of the cylinder 6.

[0027] Specifically, the rotating joint 5 includes a motor and a housing, which is existing technology; when the device is performing disassembly operations, the positions of the rotating joint 5 and the joint rod 10 remain unchanged; when the template falls onto the suction cup 2, the relative positions of the rotating joint 5 and the joint rod 10 are changed by the drive of the motor output end inside the rotating joint 5, thereby causing the template to tilt and slide in a specific direction, thus realizing the collection of the disassembled template.

[0028] Reference Figures 1-2 A fixing block 17 is fixedly installed at the output end of motor 4, and the top of the fixing block 17 is fixedly connected to the bottom of the connecting rod 14. Four motors 4 are arranged around the top of the base 1. The fixing block 17 enables modular connection between motor 4 and connecting rod 14, improving the convenience of installation, disassembly and maintenance of this component.

[0029] Reference Figures 1-2 A slip ring 15 is slidably connected to the outer wall of the connecting rod 14, and the top of the slip ring 15 is fixedly connected to the bottom of the suction cup 2. When the drill bit 3 operates on the template, the suction cup 2 moves downward under the reaction force of the template through the sliding connection between the slip ring 15 and the connecting rod 14, so that the operation of the suction cup 2 and the drill bit 3 does not interfere with each other.

[0030] Reference Figures 2-4A spring 16 is provided on the top of the fixed block 17, and the bottom of the slip ring 15 is provided on the upper end of the spring 16. The spring 16 and the outer wall of the connecting rod 14 are slidably connected. A spring is provided inside the sliding hole of the sliding cylinder 11. The lower end of the spring inside the sliding hole of the sliding cylinder 11 is fixedly connected to the upper end of the sliding rod 23.

[0031] Specifically, when the drill bit 3 operates on the template, the suction cup 2 moves downward under the reaction force of the template, causing the spring 16 to be in a compressed state. When the template separates from the concrete layer and falls, the cylinder 6 contracts, driving the drill bit 3 to descend. Through the rebound of the spring inside the slide cylinder 11, the slide cylinder 11 moves upward until the locking device 22 locks the bottom of the slide cylinder 11, thereby causing the upper end of the main umbrella rib 19 to retract into the groove of the drill bit 3. Through the rebound of the spring 16, the slip ring 15 moves upward on the connecting rod 14, thereby causing the suction cup 2 to move upward, and the top of the suction cup 2 is higher than the top of the drill bit 3, thus catching the falling template.

[0032] Reference Figures 2-4 The lower end of the slide cylinder 11 has a sliding hole. The sliding hole of the slide cylinder 11 fits the shape of the slide rod 23. The locking device 22 includes an electromagnetic module, a locking block and a spring connected to the locking block. The electromagnetic module and the spring of the locking device 22 are located inside the slide rod 23. One end of the locking block of the locking device 22 passes through the slide rod 23 and is slidably connected to the locking hole 21.

[0033] Specifically, when the output end of cylinder 6 extends, it drives drill bit 3 to move upward and press against the template. The template exerts a reaction force on drill bit 3. The locking device 22 locks the lower end of slide cylinder 11 by a locking block, thus offsetting the reaction force of the template and allowing drill bit 3 to drill into the template. When the top of drill bit 3 presses against the concrete layer, the output end of cylinder 6 retracts slightly, and the electromagnetic module of locking device 22 is energized, causing the locking block of locking device 22 to retract into the interior of slide rod 23. The output end of cylinder 6 continues to extend, allowing slide cylinder 11 to continue to move downward. During the downward movement of slide cylinder 11, the electromagnetic module of locking device 22 is de-energized, and the spring of locking device 22 rebounds against the locking block, causing it to slide on the inner wall of slide cylinder 11 until it slides into locking hole 21, thereby stopping the downward movement of slide cylinder 11. The retraction of the output end of cylinder 6 causes the main umbrella rib 19 to pass through the upper end of the template and apply downward force to the template, thus realizing the disassembly of the template.

[0034] Reference Figure 1 The bottom of cylinder 6 is located at the top of rotating mechanism 7, and a frame 9 is provided on the outer wall of rotating mechanism 7. A running mechanism 8 is provided at the bottom of frame 9.

[0035] Specifically, the rotating mechanism 7 allows the cylinder 6 to rotate on top of the frame 9, which is existing technology. When using this device, the frame 9 is moved below the template to be disassembled by the running mechanism 8, and the rotation of the rotating mechanism 7 causes the cylinder 6 to rotate, thereby achieving the adjustment of the device.

[0036] Reference Figures 2-3 The outer wall of the drill bit 3 has a groove, the lower end of the main umbrella rib 19 is set on the outer wall of the ferrule 13, the upper end of the main umbrella rib 19 is set in the groove of the drill bit 3, and the top of the barb 20 is spherical.

[0037] Specifically, there are eight main umbrella ribs 19. When the drill bit 3 is working, the locking device 22 fixes the slide cylinder 11, so that the main umbrella ribs 19 are located inside the groove of the drill bit 3, without interfering with the operation of the drill bit 3, and move upward together with the drill bit 3 to abut against the concrete layer. When the main umbrella ribs 19 are opened, the upper end of the main umbrella ribs 19 opens and extends at the gap between the template and the concrete layer, making the gap between the template and the concrete larger until the template falls off. The spherical shape of the top of the barb 20 reduces the resistance of the main umbrella ribs 19 extending at the gap between the template and the concrete.

[0038] Working principle: When using this device, the running mechanism 8 moves the device below the template to be disassembled, and the rotating mechanism 7 adjusts the device to a suitable position. The extension movement of the output end of the cylinder 6 drives the base 1 to rise, causing the drill bit 3 to contact the template. Due to the reaction force of the template and the action of the spring 16, the suction cup 2 moves downward through the sliding connection of the slip ring 15 on the connecting rod 14, without interfering with the operation of the drill bit 3. The locking device 22 locks the lower end of the slide cylinder 11, counteracting the reaction force of the template. The force exerted by the drill bit 3 on the template is constant. Driven by the output of motor 4, the drill bit 3 rotates. After drilling into the template and pressing against the concrete layer, motor 4 stops, and the output of cylinder 6 slightly retracts, eliminating the force between the drill bit 3 and the concrete layer. The electromagnetic module of locking device 22 is energized, causing the locking block to retract into slide rod 23. The output of cylinder 6 continues to extend, and through the sliding connection between slide cylinder 11 and slide rod 23, the reaction force of the concrete layer on the drill bit 3 causes slide cylinder 11 to move downwards, via the clamping sleeve 1. The rotatable connection between the main umbrella rib 19 and the auxiliary umbrella rib 18, the rotatable connection between the main umbrella rib 19 and the auxiliary umbrella rib 18, and the rotatable connection between the clamping sleeve 13 and the main umbrella rib 19, allows the upper end of the main umbrella rib 19 to extend as the drill bit 3 passes through the template and open at the gap between the template and the concrete, thus widening the gap. During the downward sliding of the slide cylinder 11, the electromagnetic module of the locking device 22 is de-energized, and the locking block of the locking device 22 springs back under the action of the spring, causing it to slide into the locking hole 21 during the downward movement of the slide cylinder 11, thereby stopping the downward movement of the slide cylinder 11. Then, the output end of the cylinder 6... The contraction of the main umbrella rib 19 causes it to pass through the upper end of the template and exert downward force on the template until the template falls off and is caught by the suction cup 2. Then, the cylinder 6 contracts, the electromagnetic module of the locking device 22 is powered, and under the action of the spring inside the slide cylinder 11, the slide cylinder 11 moves upward, thereby causing the upper end of the main umbrella rib 19 to retract into the groove of the drill bit 3. Under the action of the spring 16, the top of the suction cup 2 rebounds upward and is higher than the drill bit 3. By rotating the joint 5, the base 1 tilts towards the set direction, thereby causing the template to slide off, thus improving the efficiency of dismantling the building template.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
