Description

Technical Field

[0001] This invention relates to the field of strength testing technology, specifically to a transverse displacement and side-rotation installation testing device for outward-inclined double arch ribs. Background Technology

[0002] During the overall installation of a bridge, the lateral movement and rotation of the outward-sloping double arch ribs are typically required. Due to the large-scale installation needs of bridges, large cranes are generally used for the lateral movement and installation of components. To ensure strength, the crane installation requires the laying of tracks using components such as structural steel. To ensure project quality, the strength of the fixed steel components in the tracks needs to be tested. However, existing installation testing devices have the following problems in use:

[0003] Because the steel sections used for bridge track installation are mostly large in size, they usually require large testing equipment. When conducting multi-point testing on the steel sections, a conveying mechanism is needed to move and test them. Existing installation and testing devices are not convenient for stable conveying of the steel sections. When the steel sections are subjected to pressure testing, some unqualified areas are prone to forming indentations. Using conventional conveying mechanisms, the conveying force is often insufficient for heavy steel sections, requiring external pushing, which affects the accuracy of the test. Furthermore, the steel sections have different specifications, and existing installation and testing devices are not convenient for stable conveying and testing of steel sections of different specifications. The frictional resistance required by the conveying mechanism is different for different specifications of steel sections. How to adapt to stable conveying of steel sections with indentations greatly affects the steel section testing. At the same time, in order to ensure long-term use, it is also necessary to adjust the conveying friction for different specifications of steel sections.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0005] The purpose of this invention is to provide a transverse displacement and side rotation installation detection device for outward-inclined double arch ribs to solve the problems mentioned in the background art. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a transverse shift and side-turn installation and detection device for outwardly inclined double arch ribs, comprising a base, mounting frames fixed on both sides of the top of the base, a conveying frame, a pressure frame and a detection frame fixed in the middle of the top of the base, the pressure frame and the detection frame being located on both sides of the conveying frame, pressure applying mechanisms being installed at the front and rear ends and the inner side of the top of the pressure frame, and laser detectors being installed at the front and rear ends and the inner side of the top of the detection frame;

[0007] It also includes a mounting base, which is arranged in opposite directions in the inner cavities at the front and rear ends of the conveyor frame via a position adjustment component. A conveyor seat is connected to the inner cavity of the mounting base via an electric push rod. A motor seat is connected to the conveyor seat via a pre-tightening component. A conveyor wheel is connected to the top of the motor seat via a built-in motor.

[0008] The preload assembly includes a mounting plate, which is connected to the motor base via a strong spring. An electromagnet is fixed to the inner side wall of the conveyor base, and the electromagnet is magnetically fixed to the outer side of the motor base. An oil adjustment assembly is provided between the mounting plate and the mounting base for adjusting the initial position of the mounting plate.

[0009] The mounting base is equipped with an abutting component, which can switch positions with the motor base.

[0010] Preferably, the mounting frame, pressure frame, and testing frame are all rotatably equipped with support rollers for supporting and placing the steel profiles.

[0011] Preferably, the position adjustment assembly includes a bidirectional screw and an adjusting rod. The bidirectional screw is longitudinally embedded in the bottom of the conveyor frame via a motor, and adjusting rods are sleeved at both ends of the bidirectional screw.

[0012] Preferably, the top of the adjusting rod is fixed to the bottom of the mounting base, and the mounting base slides in contact with the inner cavities at both ends of the conveyor frame via the adjusting rod.

[0013] Preferably, the oil adjustment assembly includes a first piston rod, which is fixed to the outside of the mounting plate and slidably disposed in a first oil tank. The first oil tank is embedded and fixed to the outer end of the conveyor seat. The first oil tank is connected to a second oil tank via a hose. The second oil tank is fixed to the side wall of the conveyor frame cavity. A second piston rod is slidably installed in the second oil tank and fixed to the outer end of the mounting seat.

[0014] Preferably, the first oil tank and the second oil tank are located on the same axis, and the second piston rod and the first piston rod move in opposite directions.

[0015] Preferably, the abutment assembly includes an abutment seat that slides and fits within the side cavity of the mounting base. A gear is provided on the inner side of the abutment seat, and the gear is rotatably embedded in the mounting base. An abutment head is connected to the inner end of the abutment seat via an elastic telescopic rod. A guide rod is fixed to the outer side of the abutment seat, and the guide rod is located within a guide groove, which is formed on the inner wall of the side cavity of the mounting base.

[0016] Preferably, the inner side of the abutment engages with the gear, the inner side of the gear engages with the outer area of ​​the conveyor seat, and the thickness of the abutment is greater than the thickness of the gear.

[0017] Preferably, the guide rod slides in contact with the guide groove, and the guide groove has a wave-shaped structure.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention features a powerful spring installed on the outside of the motor base. This spring provides a constant elastic force when the conveyor wheel contacts the steel profile, increasing friction between the wheel and the profile and improving conveying efficiency. Furthermore, when dents appear after pressure testing, the conveyor wheel can adaptively contact the dented area, improving conveying stability. This enhances multi-point testing efficiency when inspecting large steel profiles. Additionally, during pressure testing, an electric push rod retracts the conveyor base, and gears extend the contact seat. The contact seat moves up and down synchronously with the guide rod and guide groove. The elastic telescopic rod and contact head wipe the exterior of the steel profile, securing it and protecting the conveyor wheel from wear and tear that could affect subsequent conveying. It also removes surface contaminants from the steel profile, preventing them from affecting subsequent testing.

[0020] 2. In this invention, when inspecting steel sections of different widths, a bidirectional screw is driven to rotate. This, through an adjusting rod, causes two mounting seats to move in opposite directions, thereby adjusting the initial positions of the two conveying wheels. This allows the conveying wheels to contact and convey the steel section from the outside. Simultaneously, through the transmission between the second and first oil tanks, the movement of the mounting seats can adjust the initial position of the mounting plate, thereby adjusting the initial compression of the high-strength spring. This provides a foundation for the stable conveying of the subsequent conveying wheels. That is, the wider the steel section, the greater the contact force provided by the high-strength spring. This allows the conveying wheels to provide stable conveying force for steel sections of different specifications, and reduces the unnecessary losses caused by uniform contact force, thereby improving long-term efficiency.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-6 The present invention provides a technical solution: a transverse shifting and side-turning installation and detection device for outwardly inclined double arch ribs, including a base 1, mounting frames 2 fixed on both sides of the top of the base 1, a conveying frame 3, a pressure frame 4 and a detection frame 5 fixed in the middle of the top of the base 1, the pressure frame 4 and the detection frame 5 located on both sides of the conveying frame 3, a pressure applying mechanism 6 installed at the front and rear ends and the inner side of the top of the pressure frame 4, a laser detector 7 installed at the front and rear ends and the inner side of the top of the detection frame 5, and a support roller rotatably installed inside the mounting frame 2, the pressure frame 4 and the detection frame 5 for supporting and placing the steel profile;

[0030] Mounting base 9 is arranged in the inner cavity of the front and rear ends of the conveyor frame 3 through the position adjustment component. The inner cavity of mounting base 9 is connected to conveyor base 11 through electric push rod 10. The conveyor base 11 is connected to motor base 13 through pre-tightening component. The top of motor base 13 is connected to conveyor wheel 14 through built-in motor.

[0031] During testing, the steel profile is passed through the mounting frame 2, pressure frame 4, conveying frame 3 and testing frame 5, and the bottom of the steel profile is supported by the support roller. The intermittent conveying wheel 14 is driven by the motor in the motor base 13 to rotate and intermittently convey the steel profile. Then, the side and top of the steel profile are pressured by the pressure applying mechanism 6, and the pressure area of ​​the steel profile is subsequently detected by the laser detector 7 to check for dents.

[0032] In one embodiment of the present invention, the position adjustment assembly includes a bidirectional screw 81 and an adjusting rod 82. The bidirectional screw 81 is longitudinally embedded in the bottom of the conveyor frame 3 via a motor. The two ends of the bidirectional screw 81 are fitted with adjusting rods 82. The top of the adjusting rod 82 is fixed to the bottom of the mounting base 9. The mounting base 9 slides in contact with the inner cavities at both ends of the conveyor frame 3 via the adjusting rod 82.

[0033] According to the width of the steel profile, the distance between the two mounting seats 9 is adjusted. The double-acting screw 81 is driven by the motor to rotate. The double-acting screw 81 drives the two adjusting rods 82 to slide in opposite directions in the cavity inside the conveyor frame 3, thereby driving the two mounting seats 9 to move in opposite directions. The distance between the motor seat 13 and the conveyor wheel 14 inside the two mounting seats 9 is adjusted so that the two conveyor wheels 14 can be in contact with the side wall of the steel profile.

[0034] In one embodiment of the present invention, the pre-tightening force assembly includes a mounting plate 121, which is connected to the motor base 13 via a strong spring 122. An electromagnet 123 is fixed to the inner side wall of the conveying base 11, and the electromagnet 123 is magnetically fixed to the outer side of the motor base 13. An oil adjustment assembly is provided between the mounting plate 121 and the mounting base 9 for adjusting the initial position of the mounting plate 121.

[0035] The oil adjustment assembly includes a first piston rod 124, which is fixed to the outside of the mounting plate 121. The first piston rod 124 is slidably disposed inside the first oil tank 125, which is embedded and fixed to the outer end of the conveying seat 11. The first oil tank 125 is connected to a second oil tank 126 via a hose. The second oil tank 126 is fixed to the side wall of the cavity of the conveying frame 3. A second piston rod 127 is slidably installed inside the second oil tank 126 and is fixed to the outer end of the mounting seat 9. The first oil tank 125 and the second oil tank 126 are located on the same axis, and the second piston rod 127 moves in opposite directions to the first piston rod 124.

[0036] The movement of the mounting base 9 causes the second piston rod 127 to move within the second oil tank 126. Through the delivery of oil, the first piston rod 124 within the first oil tank 125 moves. That is, when the profile is wider, the mounting base 9 moves outward, squeezing the oil in the second oil tank 126 into the first oil tank 125, pushing the first piston rod 124 inward. With the electromagnet 123 locking the motor base 13, the first piston rod 124 pushes the mounting plate 121 inward to compress the force spring 122, increasing the initial compression of the force spring 122.

[0037] In one embodiment of the present invention, a contact component is provided in the mounting base 9. The contact component and the motor base 13 can switch positions. The contact component includes a contact seat 151, which slides in contact with the side cavity of the mounting base 9. A gear 152 is provided on the inner side of the contact seat 151. The gear 152 is embedded and rotated in the mounting base 9. The inner end of the contact seat 151 is connected to a contact head 154 through an elastic telescopic rod 153. A guide rod 155 is fixed on the outer side of the contact seat 151. The guide rod 155 is located in a guide groove 156. The guide groove 156 is opened on the inner wall of the side cavity of the mounting base 9.

[0038] The inner side of the contact seat 151 meshes with the gear 152, and the inner side of the gear 152 meshes with the outer area of ​​the conveyor seat 11. The thickness of the contact seat 151 is greater than the thickness of the gear 152. The guide rod 155 slides in contact with the guide groove 156, which has a wave-shaped structure.

[0039] During intermittent conveying, the electric push rod 10 drives the conveying seat 11 to retract, and the gear 152 drives the contact seat 151 to extend. The contact head 154 contacts the side of the steel profile. As the contact seat 151 continues to extend, the elastic telescopic rod 153 is compressed by force, and the contact seat 151 and the contact head 154 move up and down through the guide rod 155 and the guide groove 156. The rubber pad at the front end of the contact head 154 wipes and fixes the side of the steel profile, so that the conveying wheel 14 separates from the steel profile.

[0040] Working principle: First, adjust the distance between the two mounting seats 9 according to the width of the steel profile. The motor drives the bidirectional screw 81 to rotate, causing the two adjusting rods 82 to slide in opposite directions within the cavity of the conveyor frame 3. This, in turn, causes the two mounting seats 9 to move in opposite directions, adjusting the distance between the motor seat 13 and the conveying wheel 14 within the two mounting seats 9. This allows the two conveying wheels 14 to contact the side wall of the steel profile for conveying. Simultaneously, the movement of the mounting seats 9 causes the second piston rod 127 to move within the second oil tank 126. Through the delivery of oil, the first piston rod in the first oil tank 125... When the piston rod 124 moves, that is, when the profile is wider, the mounting base 9 moves outward, squeezing the oil in the second oil tank 126 into the first oil tank 125, pushing the first piston rod 124 inward. With the electromagnet 123 locking the motor base 13, the first piston rod 124 pushes the mounting plate 121 inward to compress the strong spring 122, increasing the initial pressure of the strong spring 122, so that it can provide a greater resistance force to the wider profile, which facilitates the stable conveying of the profile by the conveying wheel 14. Conversely, when the profile is narrow, the initial pressure of the strong spring 122 is narrow.

[0041] During testing, the steel profile is passed through the mounting frame 2, pressure frame 4, conveying frame 3, and testing frame 5, and the bottom of the steel profile is supported by the support roller. When the steel profile is contacted by the conveying wheel 14, the electromagnet 123 is de-energized. At this time, the strong spring 122 provides an elastic contact force, increasing the contact force between the conveying wheel 14 and the steel profile. The motor in the motor base 13 drives the intermittent conveying wheel 14 to rotate, intermittently conveying the steel profile. Then, the pressure mechanism 6 applies pressure to the side and top of the steel profile, and subsequently, the laser detector 7 detects the pressure area of ​​the steel profile to check for dents. The laser detector 7 uses existing laser detection technology. If there is a dent, when the conveying wheel 14 contacts it, the strong spring 122 can push the conveying wheel 14 to move, so that the conveying wheel 14 is always in contact with the steel profile and conveys it stably.

[0042] Meanwhile, during intermittent conveying, the electric push rod 10 drives the conveyor seat 11 to retract, and the gear 152 drives the contact seat 151 to extend. The contact head 154 contacts the side of the steel profile. As the contact seat 151 continues to extend, the elastic telescopic rod 153 is compressed by force, and the guide rod 155 and guide groove 156 drive the contact seat 151 and the contact head 154 to move up and down. The rubber pad at the front end of the contact head 154 wipes and fixes the side of the steel profile, so that the conveyor wheel 14 is separated from the steel profile. This avoids the conveyor wheel 14 from being worn when the steel profile is pressure tested, and at the same time wipes the steel profile to prevent dirt on it from affecting subsequent testing.

[0043] Although the present invention 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 invention should be included within the protection scope of the present invention.
