Description

Technical Field

[0001] The utility model relates to a sonic detection tube device, in particular to an internal protection device for a sonic detection tube. Background Art

[0002] The sonic detection tube is mainly used for pile foundation and ground-connected wall detection. It is a steel tube pre-buried with the steel cage. It is mainly used to put in the probe for detection. It is an indispensable tool for detecting the integrity and diameter of the pile foundation. It is widely used in the field of construction. In order to ensure that the sonic detection tube will not be blocked during the later detection and affect the subsequent normal detection, in addition, the sonic detection tube is also more susceptible to deformation caused by external forces, so corresponding protection measures need to be taken for the sonic detection tube.

[0003] At present, the protection of the ultrasonic detection pipe mainly adopts cotton cloth or wooden plug to seal the joints at the mouth of the ultrasonic detection pipe to prevent concrete blocks from entering the ultrasonic detection pipe and causing blockage of the ultrasonic detection pipe to affect the subsequent detection. However, these traditional sealing methods have some shortcomings in sealing performance, and also lack specific structures for the internal support of the ultrasonic detection pipe.

[0017] The features of the present invention and other related features are further described in detail below through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0018] like Figure 1-2 , the marks in the figure are: acoustic detection tube 1, cap 2, lifting rod 3, sleeve rod 4, support rod 5, connecting rod 6, connecting sleeve 7, pin hole 8, pin 9, connecting rope 10, inner support panel 11, through hole 12.

[0019] Example: Figure 1 , 2 As shown, this embodiment specifically relates to an internal protection device for an acoustic detection tube, which includes a cap 2 and an internal support assembly. The cap 2 is screwed to the top of the acoustic detection tube 1 by a threaded connection to seal the port, and the internal support assembly is built into the interior of the acoustic detection tube 1 for internal support to prevent deformation of the acoustic detection tube 1 caused by external forces.

[0020] like Figure 1 , 2As shown, the inner support assembly includes a lifting rod 3, a sleeve rod 4, a support rod 5, a connecting rod 6, a connecting sleeve 7, a pin hole 8, a pin 9, a connecting rope 10, a support panel 11 and a through hole 12. Among them, the sleeve 4 is coaxially sleeved on the outside of the lifting rod 3, and the length of the lifting rod 3 is greater than the length of the sleeve 4; a plurality of groups of support rods 5 are arranged from top to bottom on the outer wall surface of the sleeve rod 4, and in this embodiment, there are four groups of support rods 5, and the specific number of groups depends on the length of the acoustic detection tube 1; each group of support rods 5 includes eight support rods 5 symmetrically arranged on the outer wall surface of the sleeve rod 4, and the inner end of the support rod 5 is hinged to the outer wall surface of the sleeve rod 4 through a steering gear, and the outer end of the support rod 5 is hinged with an inner support panel 11 (rotatable relative to each other), and the inner support panel 11 is in sliding contact with the inner wall surface of the acoustic detection tube 1. In addition, a connecting rod 6 is provided between the lifting rod 3 and the upper part of the support rod 5, one end of the connecting rod 6 is hinged to the outer wall of the lifting rod 3 through a steering gear, and the other end of the connecting rod 6 is connected to the support rod 5 through a connecting sleeve 7, and the connecting sleeve 7 is slidably mounted on the support rod 5 and can slide on the support rod 5. It should be noted that through holes 12 are provided on the sleeve rod 4 at the positions corresponding to the hinged connection between the connecting rod 6 and the lifting rod 3, so as to allow the connecting rod 6 to pass through and swing up and down.

[0021] like Figure 1 , 2 As shown, a through hole is provided at the center of the cap 2 for the upper end of the lifting rod 3 to pass through, and a latch hole 8 is also provided horizontally at the upper end of the lifting rod 3. A latch 9 can be inserted into the latch hole 8 for fixing, which plays a role in fixing the lifting rod 3, preventing the user from pulling the lifting railing 3 all the time, and only needs to insert the latch 9. In order to prevent the latch 9 from being lost, a connecting rope 10 is provided between the latch 9 and the upper end of the lifting rod 3 for connection.

[0022] like Figure 1 , 2 As shown, the internal protection device can protect the acoustic detection tube 1 from the inside. The diameter of the internal protection device is slightly larger than that of the acoustic detection tube. When in use, the lifting rod 3 is pulled upward, and the internal connecting rod 6 will be lifted upward under the action of the steering gear, so that the diameter of the internal protection device becomes smaller, and the pin 9 can be inserted into the pin hole 8 to fix the lifting rod 3. Then the internal protection device is placed in the acoustic detection tube 1, the cap 2 is tightened, and then the pin 9 is taken out of the pin hole 8, and the internal support will return to its original state. Since its diameter is slightly larger than the acoustic detection tube support, it can play a supporting role inside.

[0023] In this embodiment:

[0024] ① The threaded cap 2 can be screwed onto the mouth of the acoustic detection pipe 1, which avoids the cap 2 being knocked off during the construction process and can better prevent concrete blocks from falling into the acoustic detection pipe and causing the acoustic detection pipe 1 to be blocked.

[0025] ② Each section outside the sleeve rod 4 has eight internal supports (support rods 5), which can support the inner wall of the acoustic detection tube 1 from the inside and resist deformation of the acoustic detection tube 1 caused by external forces.

[0026] ③ The steering gear can only provide a small range of rotation. Its rotation can make the inner support (support rod 5) appear to be lifted in a small range through the connecting rod 6 and the connecting sleeve 7, so that its diameter can be reduced in a small range.

[0027] ④ The design of the latch 9 can prevent the user from pulling the handrail 3 all the time. The user only needs to insert the latch 9. After installing it in the acoustic detection tube 1, the latch 9 can be taken out and the inner support can be restored to its original state.

[0028] ⑤ The sleeve rod 4 is outside the lifting rod 3 and the sleeve rod 4 is fixed and cannot be moved, so the support connected to the sleeve rod 4 can only rotate in a small range under the action of the steering gear.

[0029] ⑥ After protecting the acoustic detection tube 1, the lifting rod 3 can be pulled upwards and fixed with the latch 9, and the cap 2 can be unscrewed to disassemble and recycle the device, which is convenient for multiple uses in the future, and is easy to install, simple to operate, and green and environmentally friendly.
