Description

Technical Field

[0001] The utility model relates to the technical field of sound measuring pipe installation, and more specifically, to an auxiliary installation device for sound measuring pipes. Background Technique

[0002] In the field of pile foundation engineering, the application of sound measuring pipes is crucial. As a kind of acoustic detection pipe, sound measuring pipes can effectively evaluate the quality of pile foundations and ensure the safety and reliability of engineering structures. As the core component of the ultrasonic detection system for cast-in-place piles, sound measuring pipes not only provide a channel for the detection probe to enter the inside of the pile body, but also the embedding method and the layout form on the pile cross-section directly affect the accuracy and reliability of the detection results.

[0003] In current construction practices, construction workers need to symmetrically arrange no less than two sound measuring pipes inside the steel reinforcement cage according to the specific size of the pile foundation. However, due to the complexity of the construction environment and the limitations of manual operations, it is very difficult to ensure their strict symmetrical distribution when fixing the sound measuring pipes, which not only increases the construction difficulty but also affects the accuracy of the detection results. Content of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides an auxiliary installation device for sound measuring pipes to solve the above problems.

[0005] The utility model is implemented as follows:

[0006] An auxiliary installation device for sound measuring pipes includes a screw rod, on which two support arms are arranged. The support arms include a first bushing and a second bushing that are threadedly connected to the screw rod. A number of side ears are circumferentially and equally divided on the outer surface of the first bushing, and the second bushing is provided with the same side ears as the first bushing. A support rod is hinged to each side ear. A number of horizontal brackets are arranged on the outside of the support arms. Third hinge holes are arranged at both ends of the horizontal brackets, and first hinge holes and second hinge holes are respectively arranged in the middle of the horizontal brackets. The support rods on the two support arms in the same length direction are respectively hinged to the adjacent first hinge holes and second hinge holes, and pipe contact wheels are arranged in the third hinge holes.

[0007] In an embodiment of the utility model, a through hole is arranged at the nut of the screw rod, and a handle is arranged at the through hole.

[0008] In an embodiment of the utility model, the thread directions of the first bushing and the second bushing are opposite. When the screw rod is rotated, the first bushing and the second bushing approach or move away from each other.

[0009] In an embodiment of the utility model, an inner concave part is arranged on the outside of the pipe contact wheel.

[0010] In an embodiment of the present invention, a non-slip layer is provided on the surface of the inner recess.

[0011] In an embodiment of the present invention, the anti-slip layer is a rubber anti-slip layer.

[0012] In an embodiment of the utility model, a pull ring is provided on one end of the screw rod away from the handle, and a rope is provided on the pull ring.

[0013] The beneficial effects of the utility model are as follows: through the rotation of the screw, the position of the horizontal bracket and the pipe contact wheel can be conveniently and quickly adjusted to realize the rapid positioning and fixation of the acoustic detection tube. Compared with the traditional manual adjustment method, it greatly saves construction time and improves installation efficiency; the design of the device ensures that the acoustic detection tube can be symmetrically distributed inside the steel cage, avoiding the position deviation of the acoustic detection tube caused by improper operation of the construction personnel, and the symmetrically distributed acoustic detection tube can better reflect the overall quality of the pile foundation and improve the accuracy of detection; the operation of the device is simple and easy to understand, and the construction personnel only need to rotate the screw and pull the rope to complete the fixation and movement of the acoustic detection tube. This operation method reduces the construction difficulty and reduces the labor intensity of the construction personnel; the device can select a suitable model according to the size of the steel cage and the number of acoustic detection tubes, and has strong adaptability.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0020] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model claimed, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0021] As Figure 1-2 shown, the present utility model provides an auxiliary installation device for acoustic pipes, including a screw rod 10. Two adjustable support arms 12 are arranged on the screw rod 10. The support arm 12 includes a first shaft sleeve 1201 and a second shaft sleeve 1202 that are threadedly connected to the screw rod 10. A plurality of side ears are circumferentially and equally spaced on the outer surface of the first shaft sleeve 1201. The second shaft sleeve 1202 is provided with the same side ears as the first shaft sleeve 1201. A plurality of horizontal brackets 13 are arranged on the outer side of the support arm 12. The number of horizontal brackets 13 is the same as the number of side ears on the first shaft sleeve 1201. Third hinge holes 1303 are arranged at both ends of the horizontal bracket 13. First hinge holes 1301 and second hinge holes 1302 are respectively arranged in the middle of the horizontal bracket 13. A support rod 1203 is hinged on each side ear. The ends of the support rods 1203 in the same length direction are connected together by pins, and the pins are respectively hinged to the adjacent first hinge hole 1301 and second hinge hole 1302. Pipe abutting wheels 14 are arranged in the third hinge holes 1303. These pipe abutting wheels 14 can abut the acoustic pipes against the inner side wall of the steel reinforcement cage, thus simplifying the operation process of construction workers. By simply rotating the screw rod 10, all the horizontal brackets 13 can be simultaneously expanded outwards or contracted inwards, realizing the rapid positioning and fixing of the acoustic pipes. After one fixing is completed, the construction workers can move this auxiliary installation device to move it within the steel reinforcement cage until the entire acoustic pipe is completely fixed. During this process, the symmetrical distribution of the acoustic pipes is ensured, providing a solid foundation for the detection of pile foundation projects.

[0022] It should be noted that the embedded quantity of the sonic logging tubes is directly proportional to the size of the pile foundation. The larger the size of the steel reinforcement cage, the more sonic logging tubes are required. Therefore, the type of the support arm 12 selected (i.e., the number of side ears is the same as the number of required sonic logging tubes) should correspond to it. In this embodiment, three sonic logging tubes are taken as an example for installation.

[0023] In this embodiment, a through hole 101 is provided at the nut of the screw rod 10, and a handle 11 is provided at the through hole 101. The handle 11 facilitates the rotation of the screw rod 10.

[0024] In this embodiment, the thread directions of the first bushing 1201 and the second bushing 1202 are opposite. When the screw rod 10 is rotated, the first bushing 1201 and the second bushing 1202 on each support arm 12 approach or move away from each other. During this process, the horizontal support 13 always approaches or moves away from the screw rod 10 along its orthographic projection direction.

[0025] As Figure 3 shown, an inner concave portion 1401 is provided on the outer side of the pipe abutting wheel 14. During use, place this auxiliary installation device at one end inside the steel reinforcement cage, place the sonic logging tube between the inner concave portion 1401 and the steel reinforcement cage, and then rotate the screw rod 10 to expand the horizontal support 13 outward until the sonic logging tube abuts against the inner surface of the steel reinforcement cage to form a fixation.

[0026] As a preferred embodiment, an anti-slip layer is provided on the surface of the inner concave portion 1401. This anti-slip layer not only enhances the friction with the sonic logging tube, but also ensures that the device will not move due to slight external disturbances during the fixation of the sonic logging tube, thus greatly improving the stability and convenience of the fixation operation. At the same time, the anti-slip layer is preferably a rubber anti-slip layer. The texture of rubber is soft and it has good anti-slip performance. It can not only effectively prevent the device from sliding, but also increase the contact area with the sonic logging tube, further enhancing the firmness of the fixation.

[0027] In one embodiment, a pull ring is provided at the end of the screw rod 10 far from the handle 11, and a rope is provided on the pull ring. Construction workers can pull the rope at the other end of the steel reinforcement cage to move this auxiliary installation device, which is more convenient compared to construction workers moving this auxiliary installation device under the interference of the steel reinforcement cage.

[0028] Specifically, the working principle of the auxiliary installation device for acoustic detection pipes is as follows: when in use, the auxiliary installation device of a suitable model is selected according to the size of the steel cage, and it is placed at one end of the inner side of the steel cage. Then, by rotating the screw 10, all the pipe contact wheels 14 are close to the inner wall of the steel cage. Next, each acoustic detection pipe is placed in the inner recess 1401 of the pipe contact wheel 14 in the corresponding length direction, and the screw 10 is rotated again. At this time, the first sleeve 1201 and the second sleeve 1202 will approach each other. Due to the action of the support rod 1203, the horizontal bracket 13 will be synchronously expanded outwards, and the pipe contact wheel 1 4 Fix the sonic detection tube on the inner wall of the steel cage. After fixing a certain distance of the sonic detection tube, the construction personnel can pull the rope at the other end of the steel cage to move the auxiliary installation device so that it continues to move inside the steel cage, ensuring that the subsequent part of the sonic detection tube can also be firmly fixed. At the same time, it ensures that the sonic detection tube is symmetrically distributed inside the steel cage, providing a solid foundation for subsequent pile foundation engineering inspections. Through the above structure, it solves the problem that when the construction personnel symmetrically set the sonic detection tube on the inner side of the steel cage, they cannot accurately control its symmetrical distribution, and the problem that observation and fixation are carried out simultaneously not only increases the construction difficulty but also wastes construction time.

[0029] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
