DETAILED DESCRIPTION

[0028] like Figures 1 to 7As shown, the present invention provides a positioning device for aluminum alloy formwork construction, including a first formwork 1, a transmission mechanism, a limiting mechanism and an auxiliary mechanism; second formworks 2 are symmetrically installed on both sides of the first formwork 1, and the concrete stairs are shaped by cooperating with the second formworks 2; a transmission mechanism is installed on the front end surface of the first formwork 1, and the transmission mechanism can drive the second formwork 2 to move so that the second formwork 2 is fitted with or separated from the first formwork 1; a limiting mechanism is installed on the top surface of the first formwork 1, and the limiting mechanism can be adaptively adjusted according to the length of the required stair passage plane, and accurately locate the drip line position; an auxiliary mechanism is installed inside the first formwork 1, and the auxiliary mechanism can assist the first formwork 1 and the second formwork 2 to separate after the concrete stairs are shaped.

[0029] The front and rear end surfaces of the first template 1 are symmetrically fixedly connected with guide rails 3, and both ends of the guide rails 3 are slidably connected to the second template 2, and a connecting plate 4 is symmetrically fixedly connected between two adjacent guide rails 3 on the same side, and a bidirectional threaded rod 5 is rotatably installed between the two connecting plates 4 of the guide rail 3 at the front end of the first template 1, and both ends of the bidirectional threaded rod 5 are connected with sliders, and the two sliders are respectively fixed on the second template 2 at both ends.

[0030] The transmission mechanism includes a bidirectional motor 6 installed on the front end surface of the first template 1, and the output end of the bidirectional motor 6 is fixedly connected to the bidirectional threaded rod 5. When the bidirectional motor 6 is started, the bidirectional motor 6 drives the bidirectional threaded rod 5 to rotate. Since the second template 2 is fixedly connected to the slider on the bidirectional threaded rod 5, the rotation of the bidirectional threaded rod 5 drives the second template 2 to slide and move to the first template 1 through the guide rail 3, so that the first template 1 and the second template 2 are combined.

[0031] The limiting mechanism includes a drip line positioning plate 8 and a limiting plate 9. The top surfaces of the guide rails 3 on both sides are fixedly connected with a connection frame 7. The drip line positioning plates 8 are symmetrically installed on the top of the first template 1. The outer surface of the drip line positioning plates 8 is fixedly connected with the limiting plate 9. A fixed plate 10 is fixedly connected between the two drip line positioning plates 8. A push rod 11 is installed on the top surface of the fixed plate 10. A push rod motor 12 is installed on the top surface of the connection frame 7, and the output end of the push rod motor 12 is fixedly connected to the push rod 11. Start the push rod motor 12, and the push rod motor 12 drives the fixed plate 10 and the drip line positioning plate 8 to move downward together through the push rod 11. The drip line positioning plate 8 moves downward and drives the limiting plate 9 to move downward to a suitable position for concrete pouring.

[0032] The drip line positioning plate 8 is fixedly connected to the limiting plate 9, and the difference between the bottom end of the drip line positioning plate 8 and the connection point of the limiting plate 9 is 5 cm.

[0033] An observation port 13 is provided on the front end surface of the connection frame 7 , a positioning ruler 14 is fixedly connected to the front end surface of the fixing plate 10 , and a scale groove 15 is installed on the front end surface of the positioning ruler 14 .

[0034] A control panel 24 is also installed on the back surface of the connection frame 7 , and both the bidirectional motor 6 and the push rod motor 12 are controlled by the control panel 24 .

[0035] The auxiliary mechanism includes a tooth plate 16, a tooth groove 17, a rotating rod 18 and a gear 19. A tooth plate 16 is arranged between the two guide rails 3 at the rear end of the first template 1, wherein one end of the tooth plate 16 is fixed on the second template 2, and a tooth groove 17 is provided on the surface of the tooth plate 16. A plurality of rotating rods 18 are equidistantly mounted on the top surface of the first template 1, wherein a gear 19 is fixedly connected to the bottom surface of one rotating rod 18, and a mounting block 22 is fixedly connected to the bottom surface of the other rotating rods 18. The gear 19 is meshed and connected with the tooth plate 16 through the tooth groove 17, and a plurality of impact blocks 23 are equidistantly mounted on the outer surface of the mounting block 22. A pulley 20 is fixedly connected at the center of each rotating rod 18, and a connecting belt 21 is installed between the pulleys 20, and the connecting belt 21 is used to cooperate with the transmission connection.

[0036] Start the bidirectional motor 6. The bidirectional motor 6 drives the second template 2 to separate from the first template 1 and separates the second template 2 from the concrete stairs. When the second template 2 moves away from the first template 1, it drives the tooth plate 16 to move together. Since the tooth plate 16 and the gear 19 are meshed and connected through the tooth groove 17, when the tooth plate 16 moves, it drives the gear 19 to rotate. The rotation of the gear 19 drives the rotating rod 18 to rotate. The rotation of the rotating rod 18 drives the pulley 20 to rotate. The pulleys 20 are connected through the connecting belt 21 to transmit power. When the pulley 20 rotates, the mounting block 22 rotates together. The mounting block 22 rotates together and drives the impact block 23 fixedly connected on the outside to rotate. The impact block 23 rotates to knock on the inside of the first template 1, thereby helping to separate the first template 1 from the concrete stairs.

[0037] The working principle of the present invention is as follows:

[0038] When the device is needed, the bidirectional motor 6 is started, and the bidirectional motor 6 drives the bidirectional threaded rod 5 to rotate. The rotation of the bidirectional threaded rod 5 drives the second template 2 to slide to the first template 1 through the guide rail 3, so that the first template 1 and the second template 2 are combined. Then the push rod motor 12 is started, and the push rod motor 12 drives the fixed plate 10 and the drip line positioning plate 8 to move downward together through the push rod 11. The drip line positioning plate 8 moves downward and drives the limit plate 9 to move downward to a suitable position for concrete pouring. When the concrete pouring is completed and solidified, the bidirectional motor 6 is started again, and the bidirectional motor 6 drives the second template 2 to separate from the first template 1, and the second template 2 is combined. The template 2 is separated from the concrete stairs. When the second template 2 moves away from the first template 1, it drives the tooth plate 16 to move together. Since the tooth plate 16 and the gear 19 are meshed and connected through the tooth groove 17, when the tooth plate 16 moves, it drives the gear 19 to rotate. The rotation of the gear 19 drives the rotating rod 18 to rotate. The rotation of the rotating rod 18 drives the pulley 20 to rotate. The pulleys 20 are connected through the connecting belt 21 to transmit power. When the pulley 20 rotates, the mounting block 22 rotates together. The mounting block 22 rotates together and drives the impact block 23 fixed on the outside to rotate. The impact block 23 rotates to knock on the inside of the first template 1, thereby helping to separate the first template 1 from the concrete stairs.
