Detailed Implementation

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] Example:

[0033] like Figure 1-5 As shown, this embodiment provides an automatic crawler for ultrasonic testing of pipe pile butt welds, including a testing trolley 1, a clamping and guiding device, a control circuit board, and a coupling agent application device;

[0034] The inspection trolley 1 is equipped with a drive device, wheel components 2 and inspection probe 3. The drive end of the drive device is connected to the wheel components 2. The wheel components 2 slide in contact with the outer wall surface of the pipe pile. The inspection end of the inspection probe 3 is set towards the outer wall surface of the pipe pile.

[0035] The clamping guide device includes a clamping fixing member 4. One end of the clamping fixing member 4 is provided with a clamping connector, and the other end is provided with a plurality of clamping connecting parts 5. One end of the clamping fixing member 4 and the other end are connected to a clamping connecting part 5 through the clamping connector to form a clamping guide part. The clamping guide part cooperates with the pipe pile. The clamping fixing member 4 is provided with a guide rail part that cooperates with the detection trolley 1.

[0036] The coupling agent application device is located on the detection trolley 1. The coupling agent application device includes a coupling agent application box 6 and a brush wheel 7. The coupling agent application box 6 is provided with an application box cavity for placing the coupling agent. The bottom of the coupling agent application box 6 is located at an outlet that communicates with the application box cavity. The brush wheel 7 is located at the outlet and contacts the outer wall surface of the pipe pile.

[0037] The control circuit board is located on the detection trolley 1 and is electrically connected to the drive device and the detection probe 3.

[0038] In this embodiment, the inspection trolley 1 is moved within a limited range relative to the weld surface of the pipe pile 14 by the guide rail on the clamping guide device. The inspection probe 3 is an ultrasonic inspection probe 3. The coupling agent application device applies coupling agent to the weld of the pipe pile. After the coupling agent application is completed, the inspection probe 3 inspects the butt weld of the pipe pile. The above operations of applying coupling agent and inspection can be automatically realized by the control circuit board, meeting the requirements of automation and improving inspection efficiency.

[0039] Meanwhile, as the inspection trolley 1 moves relative to the outer wall of the pipe pile, the coupling agent application device is positioned in front of the inspection probe 3. This allows the coupling agent to be applied shortly before the inspection probe 3 is detected. Furthermore, the coating wheel 7 contacts the outer wall of the pipe pile, enabling the coupling agent to adhere quickly and tightly to the weld surface of the pipe pile. This prevents the coupling agent from being lost on the pipe pile due to gravity, thus avoiding detection errors caused by poor coupling during subsequent inspections.

[0040] The specific structure of the clamping guide device in this embodiment is as follows:

[0041] The clamping and fixing component 4 is a clamping component with an opening. The two sides of the opening are one end and the other end of the clamping and fixing component 4. One end and the other end of the clamping component are connected to form a clamping guide with a ring structure.

[0042] Specifically, the clamping connectors are connecting bolts and nuts, and the clamping connection part 5 is a connecting hole, with several connecting holes arranged along the length of the clamp.

[0043] Specifically, an L-shaped protrusion 8 is provided on the edge of the clamp and along the length of the clamp, and a guide rail is formed between the L-shaped protrusion 8 and the outer wall surface of the pipe pile.

[0044] The inspection trolley 1 is equipped with guide wheels 9 that cooperate with the guide rail.

[0045] In the above structure, the clamp is a flexible steel structure. The size of the clamping guide can be adjusted according to the size of the pipe pile, and the connecting bolts are matched with the corresponding connecting holes. Then, the nut locks the connecting bolts to fix the clamp to the pipe pile.

[0046] In this embodiment, there are two clamping and fixing members 4, which are arranged opposite to each other on both sides of the detection carriage 1 to limit the position of the detection carriage 1 on both sides. More specifically, the two clamping and fixing members 4 vertically limit the detection carriage 1 to the weld surface of the pipe pile, so that it can move within the limited position range. At the same time, the L-shaped protrusion 8 presses the detection carriage 1, limits the position of the detection probe 3, and prevents the detection carriage 1 from sliding in the length direction of the pipe pile. This ensures that the center of the detection probe 3 is consistent with the center line of the weld during detection and will not be offset, thus preventing the detection probe 3 from deviating from the weld and causing missed detection.

[0047] In this embodiment, the mounting structure for the detection probe 3 is as follows:

[0048] First, a square through groove is provided in the middle of the inspection carriage 1. A bendable steel plate 10 is provided in the square through groove. The steel plate 10 has a round hole that matches the inspection probe 3. The inspection carriage 1 is provided with a probe fixing device for fixing the inspection probe 3.

[0049] Specifically, the probe fixing device includes several probe fixing seats 11 arranged around the detection probe 3. The probe fixing seats 11 are provided with fixing bolts 12, one end of which abuts against the detection probe 3.

[0050] Specifically, steel plate component 10 is an arc-shaped elastic steel sheet component.

[0051] In the above structure, since the steel plate 10 is an arc-shaped elastic steel sheet, the degree of pressure of the detection probe 3 on the weld can be adjusted by adjusting the relative displacement of the detection probe 3 in combination with the elastic deformation of the steel plate 10. Then, it can be fixed by the fixing bolt 12 to observe the detection echo and make corresponding adjustments.

[0052] The bottom of the coupling agent application box 6 in this embodiment is provided with an outwardly protruding guide channel 13. The channel opening size at one end of the guide channel 13 is larger than the channel opening size at the other end. The larger channel opening communicates with the application box cavity, and the outlet is a smaller channel opening.

[0053] The above structure allows the coupling agent in the coupling agent application box 6 to pass through the guide channel 13. With the guide channel 13 having a larger opening size at one end than at the other end, pressure is applied, enabling the coupling agent to quickly enter the coating wheel 7. This allows the coating wheel 7 to continuously replenish the amount of coating applied, thus solving the problem of inconsistency between the direction of gravity and the application direction.

[0054] In this embodiment, the inspection trolley can be equipped with a power supply unit, and the movement and stopping of the inspection trolley are controlled by a control circuit board to automatically complete the "crawling-coupling-scanning" process. No external power cord is required, preventing the power cord from getting tangled with the pipe pile body during inspection.

[0055] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
