Description

Technical Field

[0001] This invention relates to the field of prestressed beam testing technology, specifically to a prefabricated concrete prestressed beam testing device. Background Technology

[0002] Prestressed beams usually refer to prestressed box girders. Some box girders are made of concrete. Among them, precast concrete prestressed beams are box girders that are prefabricated and transported to the installation site for direct installation.

[0003] A search revealed a device for detecting the grout fullness of prestressed beams, published under publication number CN213544407U. This device uses a rotating shaft to drive a screw rod, which, due to the limiting action of a limiting block, moves up and down to adjust the detection position. The X-ray collector can detect the internal structure of the beam and display the results through an image collector. However, during the detection process, the box girder has a hollow interior, requiring external detection by rotating it around the entire beam and inspecting different heights, resulting in low detection efficiency.

Fixed components are fixedly connected to both sides of the sliding rod at the top position. A fixed axis is provided. Pull ropes are fixedly connected to the upper surfaces of the two turntable frames. One end of the pull rope is fixedly connected to a mounting bracket. A radiation collector is fixedly connected inside the mounting bracket. Two connecting plates are fixedly connected to the bottom outer wall of the mounting bracket. A fixed shaft passes through the connecting plates and is rotatably connected to the connecting plates. A torsion spring fixed to the connecting plates is fixedly connected to the outside of the fixed shaft. The upper surface of the vehicle body is provided with a mounting component that allows the slide rod to move up and down reciprocally. A first helical gear is fixedly connected to the bottom of the two turntable frames. The bottom of the vehicle body is provided with a drive mechanism that drives the turntable frames to rotate.

[0009] Furthermore, the drive mechanism includes two fixed rods, both of which are fixedly connected to the bottom of the vehicle body. Sliding tubes are slidably connected to the outer sides of both fixed rods. A first spring is fixedly connected to the bottom of each fixed rod, and the first spring is fixed to the inner wall of the bottom of the sliding tube. A rotating shaft is rotatably connected between the two sliding tubes. Two auxiliary wheels are fixedly connected to the outer circumference of the rotating shaft. A second pulley is keyed to the outer circumference of the rotating shaft. A clearance groove penetrating the vehicle body is provided at the bottom of the vehicle body. Multiple mounting plates are fixedly connected to the upper surface of the vehicle body. A connecting shaft is rotatably connected between two adjacent mounting plates, and the connecting shaft is located below the turntable frame. A second helical gear is keyed to the outer circumference of the connecting shaft, and the second helical gear meshes with a first helical gear. A first pulley is keyed to the outer circumference of the connecting shaft. A belt is wound between the first pulley and the second pulley, and the belt passes through the clearance groove. A guide component is provided in the clearance groove to change the direction of the belt. An adjustment component is provided in the clearance groove to keep the belt taut.

[0010] Based on the aforementioned scheme, the guiding component includes two guide wheels, both of which are rotatably connected in the clearance groove, and the belt is wound around the guide wheels.

[0011] As a further embodiment of the present invention, the adjusting assembly includes an L-shaped rod, which is fixedly connected to the inner wall of one side of the clearance groove. A second spring is fixedly connected to the upper surface of the L-shaped rod, and a slide that moves vertically along the L-shaped rod is fixedly connected to the top of the second spring.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a precast concrete prestressed beam testing device, which has the following beneficial effects:

[0017] 1. By using the vehicle body and the X-ray collector in conjunction, the vehicle body moves inside the box girder, allowing the X-ray collector to inspect the box girder from the inside. This eliminates the need for external inspection of the box girder, saving time and improving the inspection efficiency of the equipment.

[0018] 2. By adjusting the settings of the components, the belt can be kept taut at all times, preventing the second pulley from failing to drive the first pulley to rotate when the belt becomes slack, which would affect the testing equipment's ability to inspect the box girder and improve the effectiveness of the testing equipment.

[0019] 3. By setting up the connecting component, the two rotating plates can rotate synchronously, thereby turning the vehicle body and changing its direction of movement, which facilitates the movement of the testing equipment and improves the ease of use of the testing equipment.

[0027] 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.

[0028] Reference Figures 1-6A precast concrete prestressed beam testing device includes a vehicle body 1. Two driven wheels 3 are located at the bottom of the vehicle body 1. Two rotating plates 7 are rotatably connected to the bottom of the vehicle body 1. Each rotating plate 7 has a drive wheel 2 on one side facing opposite directions. A connecting component is provided between the two rotating plates 7 to ensure synchronous rotation. Two ring-shaped frames 26 are bolted to the upper surface of the vehicle body 1. A turntable frame 34 is rotatably connected to the top of each ring-shaped frame 26. A sleeve 2 is welded to one side of the turntable frame 34. 7. A sliding rod 28 is slidably connected inside the sleeve 27. Fixed shafts 30 are welded to both sides of the sliding rod 28 at the top position. Pull ropes 33 are adhered to the upper surfaces of both turntable frames 34. A mounting bracket 31 is adhered to one end of each pull rope 33. A radiation collector 32 is fixed inside the mounting bracket 31 by bolts. Two connecting plates are welded to the bottom outer wall of the mounting bracket 31, and the fixed shaft 30 passes through and is rotatably connected to the connecting plates. A torsion spring 29, fixed to the connecting plates, is welded to the outside of the fixed shaft 30. (Vehicle body 1) The upper surface of the device is provided with a mounting component that allows the slide rod 28 to move up and down reciprocally. The bottom of each of the two turntable frames 34 is fixed with a first helical gear 13 by bolts. The bottom of the vehicle body 1 is provided with a drive mechanism that drives the turntable frame 34 to rotate. The vehicle body 1 is placed inside the box girder, and then the vehicle body 1 is driven by the drive wheel 2 to move with the cooperation of the driven wheel 3. During the movement of the vehicle body 1, the drive mechanism drives the turntable frame 34 to rotate. The turntable frame 34 drives the sleeve 27 to move in a circular motion. The sleeve 27 drives the slide rod 28 to move in a circular motion. The slide rod 28 drives the connecting plate to move in a circular motion through the fixed shaft 30. The connecting plate drives the mounting frame 31 to move in a circular motion. The mounting frame 31 drives the X-ray collector 32 to move in a circular motion. At the same time, under the action of the mounting component, the X-ray collector 32 will swing while moving in a circular motion, so that the X-ray collector 32 can detect the box girder from inside the box girder, without the need to detect the box girder from the outside, saving time and improving the detection efficiency of the detection equipment for the box girder.

[0029] In particular, the drive mechanism of this invention includes two fixed rods 5, both of which are welded to the bottom of the vehicle body 1. Sliding tubes 10 are slidably connected to the outer sides of both fixed rods 5. A first spring 19 is welded to the bottom of each fixed rod 5, and the first spring 19 is fixed to the inner wall of the bottom of the sliding tube 10. A rotating shaft 17 is rotatably connected between the two sliding tubes 10. Two auxiliary wheels 9 are bolted to the outer circumference of the rotating shaft 17. A second pulley 16 is keyed to the outer circumference of the rotating shaft 17. A through-hole groove 4 is provided at the bottom of the vehicle body 1. Multiple mounting plates are bolted to the upper surface of the vehicle body 1. A connecting shaft 11 is rotatably connected between two adjacent mounting plates, and the connecting shaft 11 is located below the turntable frame 34. The outer circumference of the connecting shaft 11... A key is connected to a second helical gear 15, which meshes with a first helical gear 13. A first pulley 12 is keyed to the outer circumference of the connecting shaft 11. A belt is wound between the first pulley 12 and the second pulley 16, and the belt passes through a relief groove 4. A guide component is provided in the relief groove 4 to change the direction of the belt. An adjustment component is provided in the relief groove 4 to keep the belt taut. Under the force of the first spring 19, the auxiliary wheel 9 also contacts the box beam. Therefore, during the movement of the vehicle body 1, the auxiliary wheel 9 will also rotate. The auxiliary wheel 9 will drive the rotating shaft 17 to rotate, and the rotating shaft 17 will drive the second pulley 16 to rotate. The second pulley 16 drives the first pulley 12 to rotate via the belt, and the first pulley 12 drives the connecting shaft 11 to rotate. The second helical gear 15 rotates, which in turn drives the first helical gear 13 to rotate, and the first helical gear 13 drives the turntable frame 34 to rotate. The guiding component includes two guide wheels 14, both of which are rotatably connected to the clearance groove 4. The belt is wound around the guide wheels 14, which can change the direction of the belt and reduce the friction on the belt. The adjusting component includes an L-shaped rod 20, which is fixed to the inner wall of one side of the clearance groove 4 by bolts. A second spring 23 is welded to the upper surface of the L-shaped rod 20, and a slide 22 that moves vertically along the L-shaped rod 20 is welded to the top of the second spring 23. An idler wheel 21 is rotatably connected to one side of the slide 22, and the idler wheel 21 is in contact with the belt. Under the force of the second spring 23, the belt will... The idler pulley 21 on the carriage 22 is in constant contact with the belt, keeping the belt taut. The mounting components include two rings 25, both bolted to the upper surface of the vehicle body 1. The two rings 25 are located within two ring-shaped frames 26, and the slide rod 28 contacts the rings 25. Multiple evenly distributed arc-shaped grooves 24 are formed on the top of the rings 25. Because the slide rod 28 contacts the rings 25, it moves downwards along the arc of the arc-shaped grooves 24 under gravity during its circular movement. At this time, the force of the torsion spring 29 causes the connecting plate and the fixed shaft 30 to rotate. The connecting plate then drives the mounting frame 31 to rotate, which in turn drives the X-ray collector 32 to rotate.When the slide bar 28 moves upward along the arc surface of the arc-shaped groove 24, the pull rope 33 pulls the mounting frame 31, causing the X-ray collector 32 to reverse. The mounting frame 31 then causes the connecting plate and the fixed shaft 30 to reverse, thereby generating torque in the torsion spring 29. This cycle repeats, causing the X-ray collector 32 to swing. The connecting components include two connecting rods 8, which are respectively fixed to one side of the two rotating plates 7 by bolts. A mounting ring is welded to one end of each connecting rod 8, and a ball is located inside the mounting ring. A horizontal tie rod 6 is welded between the two balls, ensuring that the two rotating plates 7 rotate synchronously. The power wheel 2 includes a hub motor and a wheel.

[0030] The working principle of this embodiment is as follows: During use, the vehicle body 1 is placed inside the box girder. Then, the vehicle body 1 is driven by the drive wheel 2 to move in conjunction with the driven wheel 3. Simultaneously, under the force of the first spring 19, the auxiliary wheel 9 also contacts the box girder. Therefore, during the movement of the vehicle body 1, the auxiliary wheel 9 also rotates. The auxiliary wheel 9 drives the rotating shaft 17 to rotate, which in turn drives the second pulley 16 to rotate. The second pulley 16 drives the first pulley 12 to rotate via a belt. The first pulley 12 drives the connecting shaft 11 to rotate, which in turn drives the second helical gear 15 to rotate. The second helical gear 15 drives the first helical gear 13 to rotate, which in turn drives the turntable frame 34 to rotate. The turntable frame 34 drives the sleeve 27 to move in a circular motion, which in turn drives the sliding rod 28 to move in a circular motion. The sliding rod 28 drives the connecting plate to move in a circular motion via the fixed shaft 30, which in turn drives the mounting frame 31 to move in a circular motion. The X-ray collector 32 moves in a circular motion, while the slide rod 28 contacts the ring 25. Therefore, during this circular motion, the slide rod 28 moves downwards along the arc surface of the arc-shaped groove 24 under the influence of gravity. At this time, the force of the torsion spring 29 causes the connecting plate and the fixed shaft 30 to rotate. The connecting plate drives the mounting frame 31 to rotate, which in turn drives the X-ray collector 32 to rotate. When the slide rod 28 moves upwards along the arc surface of the arc-shaped groove 24, the pull rope 33 pulls the mounting frame 31, causing the X-ray collector 32 to reverse. The mounting frame 31 then drives the connecting plate and the fixed shaft 30 to reverse, thus generating torque in the torsion spring 29. This cycle repeats, causing the X-ray collector 32 to swing while moving in a circular motion. This allows the X-ray collector 32 to inspect the box girder from inside, eliminating the need for external inspection, saving time and improving the efficiency of the inspection equipment.
