Description

Technical Field

[0001] This invention relates to the field of testing auxiliary equipment technology, and in particular to a steel pipe concrete testing auxiliary support. Background Technology

[0002] Due to poor technical management and construction negligence, steel-concrete composite arch bridges often suffer from defects such as voids, looseness, construction joints, and poor bonding between the concrete and steel pipes, which affect the overall integrity and mechanical performance of the arch bridge to varying degrees. Therefore, monitoring and testing the construction quality of steel-concrete composite arch bridges is extremely important. Currently, ultrasonic testing is commonly used to inspect steel-concrete composites. This requires a ring-shaped support to hold the ultrasonic transducer and receiver. The quality of the steel-concrete composite is determined by the changes in the ultrasonic waveform received by the receiver. Furthermore, the angle between the transducer and receiver needs to be controlled at 180° during testing to ensure better ultrasonic wave reception and improve testing efficiency. However, the specifications and dimensions of different types of steel-concrete composites vary, requiring adjustment of the ring-shaped support diameter to facilitate the installation of the transducer and receiver. This necessitates readjusting the positions of the transducer and receiver to meet the 180° installation requirement, thus hindering the efficiency of steel-concrete composite testing. Therefore, we propose an auxiliary support for the testing of steel-concrete composites. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of low efficiency in existing steel-concrete pipe testing, and to propose an auxiliary support for steel-concrete pipe testing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An auxiliary support for testing steel pipe concrete includes a support frame, on which an adjustment mechanism is provided for adjusting the fit between the equipment and the steel pipe concrete.

[0006] The adjustment mechanism includes a tension rod and a compression rod rotatably mounted on the support frame and perpendicular to each other. Each tension rod and compression rod has a receiving cavity. An extension rod that is slidably mounted in each receiving cavity and fixed to another tension rod or compression rod is also mounted in the cavity. Each tension rod and compression rod has a mounting assembly for mounting an ultrasonic transmitter or receiver on its upper part. The included angle between the mounting assemblies on opposite sides is 180°. Each tension rod and compression rod has a synchronization assembly for controlling the synchronous movement of the tension rod and compression rod.

[0007] Preferably, the synchronization component includes a synchronization gear rotatably mounted in the receiving cavity, a winding roller coaxially fixed on the upper part of the synchronization gear, a traction rope wound around the outside of the winding roller, synchronization teeth meshing with the synchronization gear on one side of the extension rod, and a tension rod and a compression rod rotatably mounted on the same support frame, with traction ropes inside them fixedly connected to each other.

[0008] Preferably, a fixed rack is elastically installed in the receiving cavity within any of the tension rods, and one side of the fixed rack meshes with a synchronous gear, with one end of the fixed rack slidingly extending to the outside of the tension rod.

[0009] Preferably, the inner side of the support frame is provided with an adsorption assembly that fits into the steel pipe concrete. The adsorption assembly includes an auxiliary rotating cylinder rotatably installed in the support frame, and the outside of the auxiliary rotating cylinder is slidably engaged with the traction rope. An auxiliary gear is synchronously fixed at the lower part of the auxiliary rotating cylinder. An auxiliary tooth is elastically installed on the outside of the auxiliary gear. The auxiliary gear meshes with an auxiliary rack through the auxiliary tooth, and an adsorption magnet is fixedly installed at one end of the auxiliary rack.

[0010] Preferably, the inner side of the support frame is provided with an adsorption arc plate that fits into the steel pipe concrete. The adsorption arc plate is provided with an auxiliary slide for the auxiliary rack and the adsorption magnet to slide. The rotating end of the auxiliary rack is provided with a limiting rotating block. The support frame is provided with a leveling cavity.

[0011] Preferably, the support frame is provided with a limiting component to restrict the rotation of the tension rod or compression rod. The limiting component includes a limiting groove formed on the tension rod or compression rod, a limiting block slidably installed in the limiting groove, a trigger rod fixedly installed on the upper part of the limiting block, and the upper part of the trigger rod slidably extending to the outside of the support frame. A limiting spring with both ends fixed to the support frame and the tension rod or compression rod respectively is wound around the outside of the trigger rod.

[0012] Preferably, the mounting assembly includes a mounting groove formed on the tension rod or compression rod, a rotating plate is provided in the mounting groove, and a mounting plate is provided above the rotating plate. A sliding cavity is formed in the rotating plate, and a plurality of abutment rods are fixedly installed in the sliding cavity. One side of the abutment rod abuts against abutment rod 2 that is elastically hinged to the mounting plate. A drive rod is coaxially fixed to one side of the abutment rod 2, and one end of the drive rod slides to the outside of the tension rod or compression rod.

[0013] Preferably, the bottom of the rotating plate is provided with four insert rods arranged in a circumferential array, and the mounting groove is provided with insertion holes that slide with the insert rods.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention reduces the difficulty of adjusting the equipment size by using components such as tension rods and compression rods, and reduces additional adjustment steps, greatly improving the equipment's detection efficiency for steel-concrete composite pipes. In addition, the installation components ensure that the angle between the ultrasonic transmitter and receiver remains at 180°, preventing deviations due to equipment size adjustments. This avoids the need to adjust the ultrasonic transmitter and receiver after adjusting the size in traditional operations, further increasing the detection efficiency of steel-concrete composite pipes.

[0016] 2. This invention achieves the effect of fixing the equipment on the surface of the steel pipe concrete by the contraction of the adsorption magnet, and the setting of the level cavity makes it easy for the inspection personnel to observe the horizontal placement of the equipment so as to make timely adjustments and ensure the quality of the inspection.

[0017] 3. This invention, through the mutual insertion of the plug and the socket, avoids horizontal shaking of the ultrasonic transmitter and receiver under external force, thereby ensuring the normal operation of the testing work and improving the testing effect of the 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] Example 1

[0029] Reference Figures 1-8 A steel pipe concrete testing auxiliary support includes a support frame 1. The support frame 1 is provided with an adjustment mechanism 2 for adjusting the fit size between the equipment and the steel pipe concrete. When using this device, the accommodating size of the equipment can be adjusted through the adjustment mechanism 2, so that the equipment can be fitted onto the surface of the steel pipe concrete for testing.

[0030] The adjustment mechanism 2 includes a tension rod 21 and a compression rod 22 rotatably mounted on the support frame 1 and perpendicular to each other. Each tension rod 21 and compression rod 22 has a receiving cavity 23. An extension rod 24, which is slidably mounted within each receiving cavity 23 and fixedly connected to another tension rod 21 or compression rod 22, is mounted on the upper part of each tension rod 21 and compression rod 22 with mounting components 3 for mounting an ultrasonic transmitter or receiver. The included angle between the mounting components 3 on opposite sides is 180°. Each tension rod 21 and compression rod 22 has a synchronization component 25 for controlling the synchronous movement of the tension rod 21 and compression rod 22. During adjustment, the size of the equipment can be enlarged by pulling the tension rods 21 apart. Simultaneously, under the action of the synchronization component 25, pulling any two tension rods 21 will drive all tension rods 21 and compression rods. The expansion of the support frame 22 ensures that the shape formed by the tension rod 21, compression rod 22, and support frame 1 remains a square, and the center of the diagonal of this square does not change. This facilitates the subsequent mounting of the equipment onto the steel-concrete composite surface. When shrinking, only any two compression rods 22 need to be compressed to achieve the desired effect. This adjustment method reduces the difficulty of adjusting the equipment size, reduces additional adjustment steps, and greatly improves the equipment's detection efficiency for steel-concrete composites. In addition, the angle between the ultrasonic transmitter and receiver in this device is always at 180° under the action of the mounting component 3, and will not deviate due to the adjustment of the equipment size. This avoids the need to adjust the ultrasonic transmitter and receiver after adjusting the size in traditional operations, further increasing the detection efficiency of steel-concrete composites.

[0031] Synchronization assembly 25 includes a synchronization gear 251 rotatably mounted in receiving cavity 23. A winding roller 252 is coaxially fixed to the upper part of the synchronization gear 251. A traction rope 255 is wound around the outside of the winding roller 252. One side of the extension rod 24 is provided with synchronization teeth 253 that mesh with the synchronization gear 251. A tension rod 21 and a compression rod 22 are rotatably mounted on the same support frame 1. The traction rope 255 inside the extension rod 24 is fixed to each other. Because the extension rod 24 is provided with synchronization teeth 253 that facilitate the meshing of the synchronization gear 251, the extension rod 24 can stretch as the synchronization gear 251 is engaged. During the synchronous movement of rod 21, the synchronous gear 251 will rotate through tooth meshing. When the synchronous gear 251 rotates, it can rotate the traction rope 255 by winding the winding roller 252 fixed coaxially with it. In turn, the winding traction rope 255 drives the synchronous gear 251 installed in the adjacent compression rod 22 of the tension rod 21 to rotate. When the synchronous gear 251 rotates, it can mesh with the extension rod 24 on the compression rod 22 to control the expansion of the compression rod 22. In summary, the synchronous expansion of the equipment can be controlled. The reverse is also true.

[0032] A fixed rack 254 is elastically installed in the receiving cavity 23 within any tension rod 21, and one side of the fixed rack 254 meshes with the synchronous gear 251. One end of the fixed rack 254 slides to the outside of the tension rod 21. Under normal conditions, the fixed rack 254 prevents the synchronous gear 251 from rotating by meshing with it, thus preventing the equipment from being easily adjusted in size. During formal adjustment, the fixed rack 254 can be disengaged from the synchronous gear 251 by squeezing the part of the fixed rack 254 that extends outside the tension rod 21, facilitating the adjustment of the equipment. After the adjustment is completed, the fixed rack 254 is released, and the fixed rack 254 re-meets the synchronous gear 251, thereby improving the adjustment stability of the equipment.

[0033] An adsorption assembly 26 is provided inside the support frame 1 to fit against the steel pipe concrete. The adsorption assembly 26 includes an auxiliary rotating drum 261 rotatably installed inside the support frame 1, and the outside of the auxiliary rotating drum 261 is slidably engaged with the traction rope 255. An auxiliary gear 262 is synchronously fixed at the lower part of the auxiliary rotating drum 261. An auxiliary tooth 264 is elastically installed on the outside of the auxiliary gear 262. The auxiliary gear 262 meshes with an auxiliary rack 263 through the auxiliary tooth 264. An adsorption magnet 265 is fixedly installed at one end of the auxiliary rack 263. When the compression rod 22 controls the device to approach the steel pipe concrete, it will drive the traction rope 255 to move in the support frame 1. The friction between the auxiliary rotating drum 261 and the traction rope 255 will drive the auxiliary gear 262 to rotate. Through the meshing between the auxiliary tooth 264 and the auxiliary rack 263, the adsorption magnet 265 will be driven to approach the steel pipe concrete. The attraction between the adsorption magnet 265 and the steel pipe will achieve the function of fixing the device, thereby facilitating the device to detect the quality of the steel pipe concrete.

[0034] The inner side of the support frame 1 is provided with an adsorption arc plate 266 that fits into the steel pipe concrete. The adsorption arc plate 266 has an auxiliary slide for the auxiliary rack 263 and the adsorption magnet 265 to slide. The rotating end of the auxiliary rack 264 is provided with a limiting rotating block. The support frame 1 is provided with a leveling cavity 4. Because the rotating end of the auxiliary rack 264 is provided with a limiting rotating block, the auxiliary rack 264 can only rotate in one direction, so that the auxiliary gear 262 will not rotate when the tension rod 21 expands. In addition, when fixing the equipment on the steel pipe concrete surface, the inspector can determine whether the equipment is placed horizontally by observing the bubbles in the leveling cavity 4, thereby improving the inspection effect of the equipment.

[0035] The support frame 1 is provided with a limiting component 27 to restrict the rotation of the tension rod 21 or the compression rod 22. The limiting component 27 includes a limiting groove 271 formed on the tension rod 21 or the compression rod 22. A limiting block 272 is slidably installed in the limiting groove 271. A trigger rod 273 is fixedly installed on the upper part of the limiting block 272, and the upper part of the trigger rod 273 slides to the outside of the support frame 1. The trigger rod 273 is wrapped with two ends that are respectively fixed to the support frame 1 and the tension rod 21 or the compression rod 22. When the equipment is placed on the surface of the steel pipe concrete, the limiting spring 274 can pull the trigger rod 273 to drive the limiting block 272 to disengage from the limiting groove 271 and contact the limiting fixation of the corresponding tension rod 21 or compression rod 22. Then, the tension rod 21 or compression rod 22 is rotated to place the equipment outside the steel pipe concrete, which is convenient for subsequent testing. Finally, the tension rod 21 or compression rod 22 is reset and limited by the limiting block 272 and the limiting groove 271, thereby improving the stability of the testing process.

[0036] Example 2

[0037] Reference Figures 1-8 This embodiment is basically the same as Embodiment 1, but with a further optimization: the mounting assembly 3 includes a mounting groove 31 formed on the tension rod 21 or compression rod 22. A rotating plate 32 is provided within the mounting groove 31, and a mounting plate 39 is provided above the rotating plate 32. A sliding cavity 35 is formed within the rotating plate 32, and several abutment rods 36 are fixedly installed within the sliding cavity 35. One side of each abutment rod 36 abuts against a second abutment rod 37 that is elastically hinged to the mounting plate 39. A drive rod 38 is coaxially fixed to one side of each second abutment rod 37, and one end of the drive rod 38 slides to the outside of the tension rod 21 or compression rod 22. Figure 1 As shown, the mounting plate 39 has mounting holes on the outside to facilitate the installation of the ultrasonic transmitter and receiver. After installation, rotating the rotating plate 32 makes the ultrasonic transmitter and receiver perpendicular to the tension rod 21 or compression rod 22. At the same time, it can pull the mounting plate 39 to move on the rotating plate 32, so that one end of the ultrasonic transmitter and receiver is close to the surface of the steel pipe concrete, thereby improving the detection quality. The mutual contact of the first contact rod 36 and the second contact rod 37 in the sliding cavity 35 can prevent the ultrasonic transmitter and receiver from moving in position. After the detection is completed, by rotating the drive rod 38, the second contact rod 37 is not engaged with the first contact rod 36, and the mounting plate 39 can be reset.

[0038] The bottom of the rotating plate 32 is provided with four insertion rods 33 arranged in a circumferential array. The mounting groove 31 is provided with insertion holes 34 that slide with the insertion rods 33. Before the mounting plate 39 rotates, the rotating plate 32 can be pulled upward to disengage the insertion rods 33 from the insertion holes 34. After rotating 90°, the rotating plate 32 can be released to allow the insertion rods 33 to re-insert into the insertion holes 34. The rotation of the rotating plate 32 prevents the ultrasonic transmitter or receiver from shaking during the detection process, thus ensuring the normal operation of the detection work.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
