Description

Technical Field

[0001] The present invention relates to the technical field of composite insulation board installation equipment, and particularly to an auxiliary fixing structure and a composite insulation board installation equipment. Background Art

[0002] In modern building construction, composite insulation boards are widely used in fields such as exterior wall insulation due to their excellent heat insulation performance. During the actual construction process, existing insulation board installation equipment transports the insulation board from the placement location to the installation location and then vertically places the insulation board at the installation location. Although the existing installation equipment can perform transportation and righting, during the construction process, due to the deviation in the placement of the insulation board, when the installation equipment inserts the insulation board onto the placement rack, since the position of the insulation board is not centered, the center of gravity shifts. Then, during the movement process, due to the construction ground not being very flat, the installation equipment vibrates, easily causing the insulation board to tilt and one end to fall to the ground. Therefore, generally one person pushes and one person holds the insulation board for transportation, resulting in a waste of manpower. In addition, during installation, after the insulation board is righted by the installation device, it still needs to be horizontally moved by the operator to adjust the position of the insulation board, resulting in a low installation efficiency problem.

Specific implementation mode

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0016] Refer to Figures 1-7 , an auxiliary fixing structure includes a placing rack 4. A support plate 11 is fixedly installed on one side of the placing rack 4. Baffles 13 for assisting in fixing the heat preservation board are provided at both ends of the support plate 11 to ensure that the heat preservation board can be stably placed between the placing rack 4, the support plate 11 and the baffle 13, and finally the heat preservation board is placed in the center position of the placing rack 4. The baffles 13 are symmetrically arranged, and the baffles 13 and the support plate 11 are connected by a control mechanism that can control the movement of the baffles 13.

[0017] With such a design, after the heat preservation board is placed on the placing rack 4, the heat preservation board can be assisted in fixing, thereby avoiding the problem that the heat preservation board falls off the placing rack 4 due to vibration or the center of gravity shifting during the movement process, and improving the stability of the equipment.

[0018] The control mechanism includes a second slider 14 provided on the side of the baffle 13 close to the support plate 11. The second slider 14 is slidably installed on the inner wall of the chute 30. The chute 30 plays a role in limiting the sliding of the baffle 13 and the second slider 14. The chute 30 is opened on the support plate 11. One end section of the support plate 11 away from the placement rack 4 is set as a right triangle. Such a design can facilitate the embedding of the support plate 11 into the bottom end of the insulation board. A second screw 15 penetrates through the inner wall of the second slider 14. The second screw 15 is threadedly connected to the second slider 14. The outer wall threads of the second screw 15 are symmetrically distributed. The second slider 14 is respectively placed at the positions of the outer wall threads of the second screw 15. Both ends of the second screw 15 are smooth and are rotatably connected to the support plate 11. Such a design can ensure that when the second screw 15 rotates, it can only rotate and will not move inside the support plate 11. The ends of the second screw 15 are rotatably installed on the inner wall of the chute 30. One end of the second screw 15 passes through the chute 30 and extends to one side of the support plate 11. A first gear 16 is fixedly installed on the outer wall of the second screw 15. The first gear 16 and the second screw 15 can be connected by bolts or snap connections. Preferably, it is bolted. The detachable design is convenient for maintaining the first gear 16. A second gear 17 is meshed with one side of the first gear 16. The second gear 17 and the support plate 11 can be connected by bolts or snap connections. Preferably, it is bolted. The detachable design is convenient for maintaining the second gear 17. A third gear 18 is meshed with the other side of the second gear 17. A fourth gear 19 is fixedly installed on one side of the third gear 18. The third gear 18 and the fourth gear 19 are coaxially connected. Between the third gear 18 and the fourth gear 19, and between the fourth gear 19 and the placement rack 4, they can be connected by bolts or snap connections. Preferably, it is bolted. The detachable design is convenient for maintaining the third gear 18 and the fourth gear 19. The second gear 17 is rotatably installed on the side wall of the support plate 11. The third gear 18 is rotatably installed on the side wall of the placement rack 4. A cam 20 is meshed with one side of the fourth gear 19. A connecting block 22 is fixedly installed at the end away from the fourth gear 19. The connecting block 22 is rotatably installed on the outer wall of the rotating shaft 21. The rotating shaft 21 is fixedly installed on the connecting seat 23. The connecting seat 23 is fixedly installed on one side of the placement rack 4. Such a design can limit the rotation angle of the cam 20 and the connecting block 22 and play a role in connecting the cam 20 at the same time. A handle 24 is fixedly installed at the end of the connecting block 22 away from the cam 20. A rotating mechanism is provided between the second slider 14 and the baffle 13 for adjusting the angle of the baffle 13 to facilitate the installation of the insulation board. Such a design, the end of the baffle 13 is arc-shaped, and the maximum length of the baffle 13 is less than the width of the support plate 11.Thus, it can be ensured that the baffle 13 can rotate on the support plate 11 without movement interference. In addition, the handle 24 is designed as a telescopic structure, such as an umbrella handle structure, which can change the moment of the lever by changing the length of the handle 24, so as to perform labor-saving operations and facilitate the control of the baffle 13.

[0019] The maximum distance from one side of the rotating shaft 21 to one end of the connecting block 22 is equal to the maximum distance from one side of the rotating shaft 21 to one end of the cam 20. With such a design, it is ensured that even when the handle 24 is damaged, when the connecting block 22 is rotated, it still remains in a labor-saving state, which facilitates the control by the staff.

[0020] The number of teeth of the fourth gear 19 is less than the number of teeth of the second gear 17 and the first gear 16, and the number of teeth of the second gear 17 is less than the number of teeth of the third gear 18. The second gear 17 is used to connect the first gear 16 and the third gear 18 to prevent the diameters of the first gear 16 and the third gear 18 from being too large, resulting in the bottom ends of the first gear 16 or the third gear 18 being lower than the bottom end of the support plate 11 and contacting the ground during actual operation, causing damage. The functions of the third gear 18 and the fourth gear 19 are to change the rotation speed. By rotating the fourth gear 19 by a small angle, the first gear 16 can be driven to rotate multiple circles, so as to drive the baffle 13 to move a long distance.

[0021] The rotating structure includes a rotating rod 25 fixedly installed at the top end of the second slider 14. The rotating rod 25 is embedded in the inner wall of the rotating groove 29. The rotating rod 25 is rotatably connected to the rotating groove 29. The rotating groove 29 is opened on the baffle 13. A rotating groove 29 is fixedly installed on the outer wall of the rotating rod 25. One side of the rotating groove 29 is connected to a first convex block 26. The first convex block 26 is fixedly installed on the inner wall of the rotating groove 29. One side of the first convex block 26 away from the fourth gear 19 is connected to one end of a torsion spring 27. The torsion spring 27 is sleeved on the outer wall of the bottom end of the rotating rod 25. The other end of the torsion spring 27 is fixedly installed on the inner wall of the rotating groove 29. With such a design, when the insulation board is not squeezed, the baffle 13 can be placed with both sides open. When placing the insulation board, the insulation board can drive the baffle 13 to rotate by squeezing the side of the baffle 13, which can avoid the problem that when the position of the baffle 13 is forgotten to be adjusted, the distance between the baffles 13 is insufficient or the position of the insulation board is not centered, and the insulation board directly contacts the end of the baffle 13, easily causing damage to the baffle 13, and improving the service life of the baffle 13.

[0022] Furthermore, the placement rack 4 is evenly provided with rollers 12. The top height of the rollers 12 is the same as the top surface of the placement rack 4. The rollers 12 are rotatably connected to the placement rack 4. When adjusting the baffle 13, when the baffle 13 presses the insulation board, the insulation board can be pushed, so that the insulation board moves to the center position of the placement rack 4. When pushing, the insulation board can move along the surface of the rollers 12, thereby changing the sliding friction between the insulation board and the placement rack 4 into the rolling friction between the insulation board and the rollers 12, thus playing a role in saving effort.

[0023] A composite insulation board installation device includes an installation device main body 1. One end of the installation device main body 1 is provided with a control system 2 for controlling the moving direction of the installation device main body 1. The top of the installation device main body 1 is provided with a telescopic rod 5. The telescopic rod 5 is placed on the inner wall of the placement groove 10. One end of the telescopic rod 5 is connected to the installation device main body 1 through a driving mechanism. The other end of the telescopic rod 5 is rotatably installed on one side of the placement rack 4. One end of the installation device main body 1 away from the control system 2 is fixedly installed with a support frame 6. The support frame 6 is rotatably connected to the end of the placement rack 4; among them, the installation device main body 1, the control system 2, and the telescopic rod 5 are all prior arts, so the specific structures inside them will not be described in detail one by one.

[0024] Furthermore, the driving mechanism includes a first slider 7 at one end of the telescopic rod 5. The telescopic rod 5 is rotatably connected to the first slider 7. A first screw rod 8 passes through the inner wall of the first slider 7. The first screw rod 8 is threadedly connected to the first slider 7. One end of the first screw rod 8 is connected to the output end of a servo motor 9. The servo motor 9 is fixedly installed inside the installation device main body 1; among them, the servo motor 9 is a prior art, and its internal structure will not be described in detail one by one. In addition, the input end of the servo motor 9 is connected to a logic controller through a wire. The input end of the logic controller is connected to a switch on the control system 2 through a wire. The input end of the switch is connected to a storage battery through a wire. Among them, the logic controller and the switch are common devices for those skilled in the art, so the specific structures inside them and the electrical connection relationships will not be described in detail one by one.

[0025] Working mode: When it is necessary to install the thermal insulation board, first turn on the switch on the control system 2 to control the start of the servo motor 9, so that the servo motor 9 drives the first screw rod 8 to rotate, thereby driving the first slider 7 to slide on the inner wall of the placement groove 10, and then pushing the placement rack 4 to rotate around the axis between the placement rack 4 and the support frame 6 through the telescopic rod 5, so as to adjust the placement rack 4 to a state perpendicular to the installation equipment main body 1. Then push the installation equipment main body 1, move the installation equipment main body 1 to one side of the thermal insulation board, push the installation equipment main body 1, embed the support plate 11 into the bottom of the thermal insulation board, lean the thermal insulation board against one side of the placement rack 4, and then the operator pulls the handle 24, so that the handle 24 drives the connecting block 22 and the cam 20 to rotate around the rotating shaft 21. The rotation of the cam 20 drives the fourth gear 19 to rotate, the rotation of the fourth gear 19 drives the third gear 18 to rotate, the rotation of the third gear 18 drives the second gear 17 to rotate, the rotation of the second gear 17 drives the first gear 16 to rotate, the rotation of the first gear 16 drives the second screw rod 15 to rotate, and the rotation of the second screw rod 15 drives the second slider 14 to rotate, thereby driving the baffle 13 to move towards the thermal insulation board to clamp and fix the thermal insulation board.

[0026] When the baffle 13 is in contact with the thermal insulation board, the directional force applied by the thermal insulation board will push the baffle 13 to rotate around the rotating rod 25. The rotation of the baffle 13 drives the first convex block 26 to rotate, so that the torsion spring 27 accumulates elastic potential energy until the side surface of the baffle 13 is parallel to the side wall of the thermal insulation board. Continue to move the baffle 13 so that the baffle 13 clamps the thermal insulation board, and then adjust the angle of the placement rack 4 so that the thermal insulation board is in an inclined state, so as to move the thermal insulation board to the position where it needs to be installed. Then repeat the above operation to place the thermal insulation board vertically at the position to be installed, so as to facilitate subsequent installation.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
