DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 8 An intelligent detection system for detecting the installation quality of steel structures includes a support seat 1, a steel pipe 1 3, and a steel pipe 2 4. A hand-held ring 2 is fixedly installed on the support seat 1. Two mounting rollers 8 are fixedly installed on one side of the support seat 1 through a fixed mounting assembly. An arc seat 1 9 is rotatably installed on the two mounting rollers 8 through a circular shaft 34. An arc seat 2 10 is also fixedly installed on the two mounting rollers 8. The hand-held ring 2 can be held by hand to hold the whole, or its size can be set larger and the part can be put on the arm, or the whole part can be installed on other equipment through the hand-held ring 2 for unified use.

[0033] When the equipment is in use, the connection between the steel pipe 1 3 and the steel pipe 2 4 is already in a fixed state (such as welding). The equipment can first clamp the steel pipe 1 3 and the steel pipe 2 4, and then detect the installation quality thereof.

[0034] The fixed installation component includes a fixed rod 1 5, a fixed roller 6, and a fixed rod 2 7. A fixed rod 1 5 is fixedly installed on one side of the support seat 1 close to the steel pipe 3. A fixed roller 6 is fixedly installed on one end of the fixed rod 5. Two fixed rods 2 7 are fixedly installed on the fixed roller 6, and the fixed rods 2 7 are fixedly connected to the corresponding installation rollers 8 respectively; the fixed installation component is used to fix the installation rollers 8 and the support seat 1.

[0035] Reference Figure 1-Figure 8 Two support frames 11 are fixedly installed on the support seat 1, a bidirectional screw 12 is rotatably installed between the two support frames 11, a lifting frame 13 is threadedly installed on the bidirectional screw 12, and the lifting frame 13 cooperates with the fixed installation component, and an opening and closing component is installed between the lifting frame 13 and the two circular shafts 34; the opening and closing component is used to control the rotation of the arc seat 1 9 relative to the arc seat 2 10, so as to clamp the steel pipe 1 3 and the steel pipe 2 4 when closed, and to allow the part to be directly away from the steel pipe 1 3 and the steel pipe 2 4 as a whole when opened.

[0036] The lifting frame 13 is composed of a vertical frame and two horizontal frames, and the horizontal frames are fixedly installed at both ends of the vertical frame. The bidirectional screw 12 has two sections of bidirectional threads (not shown in the figure), and the bidirectional threads are respectively matched with the two horizontal frames; the specific shape of the lifting frame 13 can be obtained from Figure 2 , Figure 3 Directly seen in.

[0037] The opening and closing components include a vertical rack 18 and a rotating gear 19. The ends of the two circular shafts 34 that are close to each other are fixed and jointly fixed with a rotating gear 19. A vertical rack 18 meshing with the rotating gear 19 is fixedly installed between the two horizontal frames. When the vertical rack 18 reciprocates in the vertical direction, it can drive the rotating gear 19 meshing with it to rotate, and the rotation angle of the rotating gear 19 only needs to meet the opening and closing of the arc seat 9.

[0038] Reference Figure 1-Figure 8 A servo motor 14 is fixedly installed on the support seat 1, and a driving shaft 15 is fixedly installed on the driving end of the servo motor 14. A first transmission component is installed between the driving shaft 15 and the bidirectional screw 12; when the servo motor 14 is working, it can drive the driving shaft 15 to perform the required forward or reverse rotation, and the first transmission component can drive the bidirectional screw 12 to rotate (unidirectional rotation). The rotation of the bidirectional screw 12 can drive the lifting frame 13 to reciprocate in the vertical direction, and the reciprocating motion realizes the opening and closing of the arc seat 9.

[0039] A controller is fixedly mounted on the support base 1, and the controller is used to control the operation of the servo motor 14, thereby achieving the required automatic intelligent use.

[0040] The first transmission component includes a one-way bearing 1, a bevel gear 16, and a bevel gear 2 17. The driving shaft 15 is mounted with the bevel gear 16 via the one-way bearing 1, and the bidirectional screw 12 is fixedly mounted with the bevel gear 2 17 meshing with the bevel gear 16. The one-way bearing 1 is arranged so that the bidirectional screw 12 can be controlled to rotate only when required (controlled by the rotation direction of the driving shaft 15).

[0041] Reference Figure 1-Figure 8 A curved rotating plate 23 is installed in the curved seat 10 in a damping sliding manner (so that the curved rotating plate 23 will not move easily when not subjected to external force and is in a relatively stable static state), and a curved rotating plate 24 is installed in the curved seat 9 in a sliding manner. The curved rotating plate 23 has the same shape as the curved rotating plate 24, but the length of the curved rotating plate 24 is greater than the length of the curved rotating plate 23 (from Figure 2 Two support cylinders (not shown) are fixedly mounted on the support seat 1, and a shaft body 28 is rotatably mounted on each of the two support cylinders. A matching direction-changing gear 29 is mounted between the two shaft bodies 28, and a driving swing structure is mounted between the shaft body 28 and the corresponding arc-shaped rotating plate 24; the driving swing structure is used to drive the arc-shaped rotating plate 24 to swing at a certain angle, and at the same time, the rotation directions of the two arc-shaped rotating plates 24 are oppositely arranged, so that the forces exerted on the steel pipe 1 3 and the steel pipe 2 4 at the same time are opposite deflection forces.

[0042] The inner walls of the arc-shaped rotating plate 1 23 and the arc-shaped rotating plate 2 24 are fixedly installed with arc-shaped elastic pads; the arrangement of the arc-shaped elastic pads can prevent the arc-shaped rotating plate 1 23 and the arc-shaped rotating plate 2 24 from directly contacting the steel pipe 1 3 and the steel pipe 2 4, and at the same time, the elasticity of the arc-shaped elastic pads can make the clamping more secure.

[0043] Reference Figure 1-Figure 8 , the installation roller 8, the arc seat 1 9, and the arc seat 2 10 are all provided with matching arc limit grooves 21, and the upper arc limit groove 21 is provided with a damping sliding installation of a limit slider 22, which is fixedly connected to the arc rotating plate 1 23, and the lower arc limit groove 21 is also provided with a limit slider 22, which is fixedly connected to the arc rotating plate 2 24; when the installation roller 8, the arc seat 1 9, and the arc seat 2 10 are Figure 2 In the closed annular state shown, a complete annular track is formed between the installation roller 8, the arcuate seat 1 9, and the arcuate seat 2 10, so that the limit slider 22 can rotate at a certain angle within the complete annular track.

[0044] The driving swing structure includes an arc-shaped rack 25, a shaft body 26, a transmission gear 27, and a transmission belt 30. A shaft body 26 is rotatably installed on the side of the two arc-shaped seats 10 that are away from each other. A transmission gear 27 is fixedly installed on the two shaft bodies 1 26. The parts of the two transmission gears 27 located outside the arc-shaped seat 2 10 are integrally formed with an arc-shaped rack 25, and the transmission gear 27 is meshed with the arc-shaped rack 25. A transmission belt 30 is sleeved between the shaft body 26 and the corresponding shaft body 28.

[0045] Reference Figure 1-Figure 8 A reciprocating screw 31 is rotatably installed on the support seat 1, a driving reciprocating rotation structure is installed between the reciprocating screw 31 and the lower shaft body 28, and a second transmission component is installed between the driving shaft 15 and the reciprocating screw 31; the setting of the reciprocating screw 31 allows the bar rack 32 to reciprocate in the horizontal direction, thereby achieving the required swing within a certain angle.

[0046] The driving reciprocating rotation structure includes a bar rack 32 and a ball nut. The bar rack 32 is installed on the reciprocating screw 31 through the ball nut, and the bar rack 32 is meshed with the changing gear 29 below; when the bar rack 32 moves back and forth, it can drive the changing gear 29 below to rotate, specifically to swing back and forth within a certain angle (the ultimate goal is to make the arc-shaped rotating plate 24 swing at the required angle).

[0047] The second transmission component includes a one-way bearing 2, a gear 20, and a gear 1 33. The gear 1 33 is installed on the driving shaft 15 through the one-way bearing 2. The reciprocating screw 31 is fixedly mounted with a gear 20 meshing with the gear 1 33. The self-locking direction of the one-way bearing 1 is opposite to the self-locking direction of the one-way bearing 2.

[0048] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0049] The working principle of the present invention is as follows: Figure 1 , Figure 2The figure shows the state when the arc seat 19 has rotated and completed the closing. At this time, the arc rotating plate 1 23 and the arc rotating plate 2 24 clamp the steel pipe 1 3 and the steel pipe 2 4, and the servo motor 14 is turned on. The servo motor 14 drives the driving shaft 15 to rotate, and the driving shaft 15 rotates through the one-way bearing 2 to drive the gear 1 33 to rotate (at this time, the one-way bearing 2 is in self-locking rotation, and the one-way bearing 1 is in a rotatable state), thereby driving the gear 2 20 to rotate, and the rotation of the gear 2 20 drives the reciprocating screw 31 to rotate, and the rotation of the reciprocating screw 31 drives the bar rack 32 to reciprocate thereon, and the bar rack 32 moves back and forth thereon. The reciprocating movement of the rack 32 can make the direction-changing gear 29 below reciprocate within a certain angle, so that the two shaft bodies 28 rotate in opposite directions. The rotation of the shaft body 28 is driven by the transmission belt 30. The rotation of the transmission belt 30 drives the arc-shaped rack 25 to rotate through the shaft body 1 26 and the transmission gear 27, thereby driving the arc-shaped rotating plate 24 to rotate. The arc-shaped rotating plate 24 can rotate by a certain angle, and will first contact the arc-shaped rotating plate 1 23 during the rotation process, thereby driving the arc-shaped rotating plate 1 23 to rotate by a certain angle together, so as to better apply a torsional test force to the connection between the steel pipe 1 3 and the steel pipe 2 4;

[0050] When the test is completed, the servo motor 14 drives the driving shaft 15 to rotate in the opposite direction. At this time, the one-way bearing 1 is in a self-locking state, and the rotation of the bidirectional screw 12 can be realized through the cooperation of the bevel gear 16 and the bevel gear 2 17. The rotation of the bidirectional screw 12 drives the lifting frame 13 to move in the vertical direction. The movement of the lifting frame 13 drives the vertical rack 18 to move. The vertical rack 18 drives the rotating gear 19 to rotate during the movement, thereby realizing the opening of the arc seat 19.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
