[0027] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0028] First embodiment:

[0029] Please refer to Figure 2-Figure 4In the first embodiment of the present invention, the supporting mechanism for installing the cantilever beam of the construction includes: a base 6, a support platform 12 is provided on the top of the base 6, and support frames 9 are fixedly installed on both sides of the support platform 12. Four electric telescopic rods 16 are fixedly installed on the top of the base 6, and the output end of the electric telescopic rod 16 is fixedly connected to the bottom of the support frame 9. A template 11 is provided on the top of the support platform 12, and two connecting holes are provided on the template 11. Four limiting connecting rods 13 are fixedly installed at the bottom of the template 11. The bottom ends of the four limiting connecting rods 13 extend to the bottom of the support frame 9 and are fixedly installed with a limiting plate 15. A first servo motor 8 is fixedly installed in the support frame 9, and an active rod 19 is rotatably installed in the support platform 12. A plurality of knocking balls 20 are fixedly installed on the outer side of the active rod 19. When the active rod 19 rotates, the knocking ball 20 is driven to rotate and continuously knock the connecting plate 22, so that the top impact plate 21 quickly hits the template 11, so as to connect the cantilever beam with the template. The plate 11 is separated, the output shaft of the first servo motor 8 extends into the support platform 12 and is fixedly connected to one end of the active rod 19, three connecting plates 22 are also provided in the support platform 12, and a plurality of impact plates 21 are fixedly installed on the top of the three connecting plates 22, and the impact plates 21 on the top of the three connecting plates 22 can form a uniform force to help the cantilever beam to be separated from the template 11, a plurality of buffer seats 23 are fixedly installed in the support platform 12, and a movable plate 18 is slidably installed in the buffer seat 23, and a first connecting rod 24 is fixedly installed on the top of the movable plate 18, and the top of the first connecting rod 24 extends to the outside of the buffer seat 23 and is fixedly connected to the bottom of the connecting plate 22, and a second spring 26 is fixedly installed on the top and bottom of the movable plate 18, when the connecting plate 22 is moving, the second spring 26 can reduce vibration to prevent the impact force from being too large, resulting in cracks on the surface of the cantilever beam, and the other ends of the two second springs 26 are fixedly connected to the buffer seat 23.

[0030] Four universal wheels 1 are fixedly mounted on the bottom of the base 6 , and first springs 14 are sleeved on the outer sides of the four limit connecting rods 13 , and two ends of the first springs 14 are fixedly connected to the template 11 and the support frame 9 , respectively.

[0031] Four fixing rods 25 are also fixedly installed in the buffer seat 23. When the connecting plate 22 moves, the direction of its impact can be controlled by the fixing rods 25 to avoid the connecting plate 22 deviating during movement and causing different impact positions. The movable plate 18 is slidably installed on the four fixing rods 25.

[0032] The working principle of the supporting mechanism for installing the cantilever beam in construction provided by the present invention is as follows:

[0033] The first step: when the cantilever beam needs to be separated from the template 11, start the first servo motor 8, and the output shaft of the first servo motor 8 drives the active rod 19 to rotate. When the active rod 19 rotates, it drives the knocking ball 20 to rotate while continuously knocking the connecting plate 22, so that the impact plate 21 continuously hits the template 11, so that the cantilever beam is quickly separated from the template 11. When the movable plate 18 moves in the buffer seat 23, the second spring 26 can reduce vibration to avoid local excessive force causing damage to the structure and the cantilever beam.

[0034] Compared with the related art, the supporting mechanism for installing the cantilever beam in construction provided by the present invention has the following beneficial effects:

[0035] Through the cooperation of the first servo motor 8, the active rod 19, the knocking ball 20, the impact plate 21 and the connecting plate 22, the active rod 19 drives the knocking ball 20 to knock the connecting plate 22 when rotating, so that the impact plate 21 continuously hits the template 11, thereby quickly separating the cantilever beam from the template 11 and reducing the time and labor intensity of manual dismantling. Secondly, through the cooperation of the second spring 26, the fixed rod 25, the buffer seat 23, the movable plate 18, the first connecting rod 24 and the first spring 14, when the knocking ball 20 continuously knocks the connecting plate 22, the second spring 26 can reduce vibration, so that the load is more evenly distributed on the supporting mechanism, avoiding local excessive force leading to damage to the structure and the cantilever beam.

[0036] Second embodiment:

[0037] Based on the supporting mechanism for installing a cantilever beam in construction provided by the first embodiment of the present application, the second embodiment of the present application proposes another supporting mechanism for installing a cantilever beam in construction. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0038] The second embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

The connecting seat 28, the other end of the connecting bracket 27 is hinged on the first fixed connecting seat 28, the two second screw rods 5 are fixedly installed with a first rotating rod 31 at one end away from the first screw rod 4, one end of the first rotating rod 31 extends to one side of the bottom support plate 2, and the outer sides of the two first rotating rods 31 are fixedly installed with a first bevel gear 30, a second rotating rod 35 is rotatably installed on one side of the bottom support plate 2, and a second bevel gear 36 is fixedly installed on the outer side of the second rotating rod 35, and two second connecting rods 33 are rotatably installed on one side of the bottom support plate 2, and a large bevel gear 32 and a small bevel gear 34 are fixedly installed at both ends of the second connecting rod 33, respectively, and pulleys are fixedly installed on the outer side of the output shaft of the first servo motor 8 and the outer side of the second rotating rod 35, and the same belt 29 is sleeved on the two pulleys.

[0040] The first screw rod 4 and the second screw rod 5 are arranged opposite to each other.

[0041] The two second connecting rods 33 are respectively located on both sides of the second rotating rod 35 . A fixing plate 37 is fixedly installed on one side of the bottom support plate 2 . A bearing 38 is rotatably installed on the outer side of the second connecting rod 33 . The bearing 38 is fixedly installed in the fixing plate 37 .

[0042] The first bevel gear 30 is meshed with the large bevel gear 32 , and the second bevel gear 36 is meshed with the small bevel gear 34 .

[0043] In this embodiment: when the cantilever beam needs to be ejected, the output shaft of the first servo motor 8 drives the second rotating rod 35 to rotate through the belt 29, and the second bevel gear 36 drives the first bevel gear 30 to rotate through the small bevel gear 34 and the large bevel gear 32 while rotating. The two movable connecting seats 3 can be moved relative to each other through the opposite arrangement of the first screw rod 4 and the second screw rod 5. When the two movable connecting seats 3 move relative to each other, the top plate 10 can lift the cantilever beam away from the template 11 through the connecting bracket 27. The present invention is provided with the above-mentioned components. When the cantilever beam needs to be removed, the two top plates 10 can provide a stable and uniform lifting force while ejecting upward, so that the cantilever beam is smoothly separated from the template 11, which facilitates the disassembly operation, saves construction time, speeds up the project progress, and secondly reduces the damage to the surrounding structure of the cantilever beam caused by improper operation during the disassembly process.

[0044] Third embodiment:

[0045] Based on the supporting mechanism for installing a cantilever beam in construction provided in the first embodiment of the present application, the third embodiment of the present application proposes another supporting mechanism for installing a cantilever beam in construction. The third embodiment is only a preferred mode of the second embodiment, and the implementation of the third embodiment will not affect the independent implementation of the second embodiment.

[0046] The third embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0047] Please refer to Figure 8-Figure 9 In the first embodiment of the present invention, side panels 39 are fixedly installed on both sides of the support platform 12, and two sealing cylinders 7 are fixedly installed on the tops of the two side panels 39. A movable plate 44 is slidably installed in the sealing cylinder 7, and a third connecting rod 42 is fixedly installed on the top of the movable plate 44. The top of the third connecting rod 42 extends to the outside of the sealing cylinder 7 and is fixedly installed with a contact plate 41.

[0048] A third spring 40 is sleeved on the outer side of the third connecting rod 42 , and two ends of the third spring 40 are fixedly connected to the bottom of the contact plate 41 and the sealing cylinder 7 respectively.

[0049] In this embodiment, when the template 11 is tilted, one side of the template 11 contacts the contact plate 41 and presses the contact plate 41 downward. While the contact plate 41 is pressed downward, the movable plate 44 is driven downward through the third connecting rod 42. When the movable plate 44 is descending, the first conductive block 45 contacts the second conductive block 46 in sequence. When the tilt is not too large, the first flashing light 43 from top to bottom flashes, so that the degree of tilt can be discovered in time. Through the arrangement of the above-mentioned components, when one side of the template 11 is tilted, the contact plate 41 drives the movable plate 44 to be pressed downward, so that the first conductive block 45 contacts the second conductive block 46, and the flashing light 43 flashes. By monitoring the horizontal state in real time, the tilt can be discovered and corrected in time, ensuring that the cantilever beam is in an accurate horizontal position, improving the stability and safety of the entire structure, and secondly, continuous monitoring can be carried out during the construction process and the subsequent use stage to discover horizontal changes caused by various factors as early as possible.
