Description

Technical Field

[0001] The present invention relates to the technical field of detection auxiliary equipment, and in particular to a steel tube concrete detection auxiliary bracket. Background Art

[0002] Due to poor technical management and negligence in construction, concrete materials often have defects such as cavities, looseness, construction joints, and poor bonding between concrete and steel pipes, which affect the integrity and mechanical properties of the arch bridge to varying degrees. Therefore, it is extremely important to monitor and detect the construction quality of steel tube concrete arch bridges. At present, ultrasonic testing is usually used to detect steel tube concrete. During the detection, an ultrasonic placer and receiver need to be placed with the help of a ring bracket. The quality of steel tube concrete is determined by the change of the ultrasonic waveform received by the receiver. In addition, during the detection process, the angle between the placer and the receiver needs to be controlled to be 180°, so that the receiver can better receive the ultrasonic wave, which is conducive to improving the detection effect. However, the specifications and sizes of different types of existing steel tube concrete are not the same. Therefore, the diameter of the ring bracket needs to be adjusted during use to facilitate the installation of the placer and the receiver, but this results in the position of the placer and the receiver needing to be readjusted to meet the 180° installation condition, which is not conducive to improving the detection efficiency of steel tube concrete. In view of this, we propose a steel tube concrete detection auxiliary bracket. Summary of the invention

DETAILED DESCRIPTION

[0027] 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.

[0028] Embodiment 1

[0029] Reference Figure 1-Figure 8 A steel tube concrete detection auxiliary bracket includes a support frame 1, and an adjustment mechanism 2 is provided on the support frame 1 for adjusting the fit size of the equipment and the steel tube concrete. When the device is used, the adjustment mechanism 2 can be used to adjust the accommodation size of the equipment, so that the equipment can be mounted on the surface of the steel tube concrete for detection.

[0030] The adjustment mechanism 2 includes a stretching rod 21 and a compression rod 22 which are rotatably mounted on the support frame 1 and are perpendicular to each other. The stretching rod 21 and the compression rod 22 are each provided with a receiving cavity 23. An extension rod 24 which is fixedly connected to the other stretching rod 21 or the compression rod 22 is slidably mounted in the receiving cavity 23. The upper part of the stretching rod 21 and the compression rod 22 is provided with a mounting assembly 3 for mounting an ultrasonic transmitter or a receiver, and the angle between the mounting assemblies 3 on the opposite side is 180°. The stretching rod 21 and the compression rod 22 are each provided with a synchronization assembly 25 for controlling the synchronous movement of the stretching rod 21 and the compression rod 22. When adjusting, the stretching rod 21 can be pulled apart to achieve the effect of expanding the size of the device. At the same time, under the action of the synchronization assembly 25, pulling any two stretching rods 21 can drive all the stretching rods 21 and the compression rods. 22 expands outward, thereby ensuring that the figure formed by the stretching rod 21, the compression rod 22 and the support frame 1 is always a square, and the diagonal center of the square will not change, which is convenient for the subsequent equipment to be mounted on the surface of the steel tube concrete. 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 tube concrete. In addition, the angle between the ultrasonic transmitter and the receiver in the device is always 180° under the action of the mounting component 3, and will not deviate due to the adjustment of the equipment size, avoiding the process of adjusting the ultrasonic transmitter and the receiver after adjusting the size in traditional operations, further increasing the detection efficiency of steel tube concrete.

[0031] The synchronization assembly 25 includes a synchronization gear 251 rotatably mounted in the accommodating chamber 23, a winding roller 252 is coaxially fixed on the upper part of the synchronization gear 251, and a traction rope 255 is wound around the winding roller 252. A synchronization tooth 253 meshing with the synchronization gear 251 is provided on one side of the extension rod 24. The stretching rod 21 and the compression rod 22 rotatably mounted on the same support frame 1, and the traction rope 255 arranged inside them are fixedly connected to each other. Since the extension rod 24 is provided with a synchronization tooth 253 that is convenient for the synchronization gear 251 to mesh, the extension rod 24 is stretched as the extension rod 24 is stretched. During the synchronous movement of the rod 21, the synchronous gear 251 will be driven to rotate through the meshing of teeth. When the synchronous gear 251 rotates, the traction rope 255 can be wound around the winding roller 252 fixed coaxially therewith to rotate, and then the traction rope 255 can be wound around to drive the synchronous gear 251 installed in the compression rod 22 adjacent to the stretching rod 21 to rotate. When the synchronous gear 251 rotates, it can be engaged with the extension rod 24 on the compression rod 22 to achieve the effect of controlling the expansion of the compression rod 22. In summary, the effect of controlling the synchronous expansion of the equipment can be achieved, and vice versa.

[0032] A fixed rack 254 is elastically installed in the accommodating cavity 23 in any stretching rod 21, and one side of the fixed rack 254 is meshed with the synchronous gear 251, and one end of the fixed rack 254 slides and extends to the outside of the stretching rod 21. Under normal conditions, the fixed rack 254 prevents the synchronous gear 251 from rotating by meshing with the synchronous gear 251, so that the device will not be easily adjusted in size. During formal adjustment, the fixed rack 254 can be squeezed to extend to the outside of the stretching rod 21 to control the fixed rack 254 to disengage from the meshing state with the synchronous gear 251, which is convenient for adjustment of the device. After the adjustment is completed, the fixed rack 254 is released and the fixed rack 254 is meshed with the synchronous gear 251 again, thereby improving the adjustment stability of the device.

[0033] An adsorption component 26 that fits the steel tube concrete is provided on the inner side of the support frame 1. The adsorption component 26 includes an auxiliary rotating drum 261 rotatably installed in the support frame 1, and the outer part of the auxiliary rotating drum 261 is slidably matched with the traction rope 255. An auxiliary gear 262 is synchronously fixed to the lower part of the auxiliary rotating drum 261, and an auxiliary tooth 264 is elastically installed on the outer part of the auxiliary gear 262. The auxiliary gear 262 is meshed with an auxiliary rack 263 through the auxiliary tooth 264, and 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 tube 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, and through the meshing between the auxiliary tooth 264 and the auxiliary rack 263, the adsorption magnet 265 is driven to approach the steel tube concrete. Through the attraction between the adsorption magnet 265 and the steel pipe, the device is fixed, so that the device is convenient for the device to detect the quality of the steel tube concrete.

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

[0035] The support frame 1 is provided with a limit assembly 27 for limiting the rotation of the stretching rod 21 or the compression rod 22. The limit assembly 27 includes a limit groove 271 provided on the stretching rod 21 or the compression rod 22, and a limit block 272 is slidably installed in the limit groove 271. A trigger rod 273 is fixedly installed on the upper part of the limit block 272, and the upper part of the trigger rod 273 slides and extends to the outside of the support frame 1. The outside of the trigger rod 273 is wrapped with two ends respectively fixedly connected to the support frame 1 and the stretching rod 21 or the compression rod 22. When the device is sleeved on the surface of the steel tube concrete, the trigger rod 273 can be pulled to drive the limit block 272 to disengage from the limit groove 271, contact the limit fixation of the corresponding stretching rod 21 or compression rod 22, and then the stretching rod 21 or compression rod 22 is rotated to sleeve the device on the outside of the steel tube concrete, which is convenient for subsequent detection. Finally, the stretching rod 21 or compression rod 22 is reset and limited by the limit block 272 and the limit groove 271, thereby improving the stability of the detection process.

[0036] Embodiment 2

[0037] Reference Figure 1-Figure 8 This embodiment is basically the same as the first embodiment, and is more optimized in that the mounting assembly 3 includes a mounting groove 31 provided on the stretching rod 21 or the compression rod 22, a rotating plate 32 is provided in the mounting groove 31, and a mounting plate 39 is provided above the rotating plate 32, a sliding cavity 35 is provided in the rotating plate 32, and a plurality of abutment rods 36 are fixedly installed in the sliding cavity 35, one side of the abutment rod 36 abuts against a second abutment rod 37 elastically hinged to the mounting plate 39, and one side of the abutment rod 37 is coaxially fixed with a driving rod 38, and one end of the driving rod 38 slides and extends to the outside of the stretching rod 21 or the compression rod 22, such as Figure 1 As shown, the mounting plate 39 is provided with mounting holes on the outside to facilitate the installation of the ultrasonic transmitter and the receiver. After the installation is completed, the rotating plate 32 is rotated so that the ultrasonic transmitter and the receiver are perpendicular to the stretching rod 21 or the compression rod 22. At the same time, the mounting plate 39 can be pulled to move on the rotating plate 32 so that one end of the ultrasonic transmitter and the receiver are close to the surface of the steel tube concrete, thereby improving the detection quality. The mutual interference between the resistance rod 1 36 and the resistance rod 2 37 in the sliding cavity 35 can avoid the ultrasonic transmitter and the receiver from moving in position. After the detection is completed, the driving rod 38 is rotated so that the resistance rod 2 37 is not engaged with the resistance rod 1 36, and the mounting plate 39 can be reset.

[0038] Four plug rods 33 distributed in a circular array are provided at the bottom of the rotating plate 32, and a socket 34 slidably matched with the plug rod 33 is provided in the mounting groove 31. Before the mounting plate 39 is rotated, the rotating plate 32 can be pulled upward to disengage the plug rod 33 at the bottom from the socket 34. After rotating 90°, the rotating plate 32 can be loosened to re-engage the plug rod 33 with the socket 34. Now the rotating plate 32 rotates, thereby preventing the rotating plate 32 from causing the ultrasonic transmitter or receiver to shake during the detection process, thereby ensuring the normal progress of the detection work.

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