Description

Technical Field

[0001] This utility model relates to the field of railway rail flaw detection, specifically to a hand-push type dual-rail ultrasonic flaw detector auxiliary tool and dual-rail ultrasonic flaw detection device. Background Technology

[0002] Rail flaw detection in railway depots is a crucial step in ensuring the safe parking of railway trains. Railway depots include two types of rail structures: tunnel-type integral track bed rails and column-type integral track bed rails. Flaw detection of tunnel-type integral track bed rails is generally carried out using a combination of large rail flaw detection vehicles and manual trolley-type ultrasonic flaw detectors (multi-probe). When using the manual trolley-type ultrasonic flaw detector, two flaw detection personnel are required for each rail (one to operate the machine and one to assist), and it takes about 0.5 hours to complete the flaw detection of tunnel-type integral track bed rails.

[0003] Due to limitations, ultrasonic flaw detectors for column-type integral track beds cannot be manually operated using handcarts (the rails are located at a high position, making it difficult and easy for the handcart-type ultrasonic flaw detector to move forward). Instead, portable ultrasonic flaw detectors (single probe) combined with manual inspection are used. This method requires two flaw detectors per rail and takes a long time to inspect the column-type integral track bed rails (approximately 3.5 hours).

[0004] Therefore, in view of the problems of slow inspection speed and difficulty in pushing the hand-push ultrasonic rail flaw detector due to the limitations of the above-mentioned tunnel-type and column-type integral track bed rail flaw detection, it is necessary to develop an auxiliary tool for the hand-push ultrasonic rail flaw detector to improve the working efficiency of ultrasonic rail flaw detection. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an auxiliary tool for a hand-push ultrasonic rail flaw detector. This auxiliary tool, through a specific structure, is fixed to the hand-push ultrasonic rail flaw detector, enabling the hand-push ultrasonic rail flaw detector to perform flaw detection on rails in column-type integral track beds. This eliminates the tipping safety hazard inherent in hand-push ultrasonic rail flaw detectors, improves stability during flaw detection operations, and ensures safe operation. Furthermore, when performing flaw detection on rails in tunnel-type and column-type integral track beds, it reduces the number of personnel required for flaw detection, freeing up labor and improving efficiency. Correspondingly, this application also provides a dual-rail ultrasonic flaw detection device.

[0006] Regarding the auxiliary tool, the technical solution of this application is as follows:

[0007] An auxiliary tool for a hand-push ultrasonic rail flaw detector includes a pair of symmetrically arranged clamping assemblies with a crossbeam between them. The clamping assemblies are used to clamp the hand-push ultrasonic rail flaw detector and include an A-frame and a B-frame. The A-frame includes a first U-shaped rod and a second U-shaped rod, which are arranged parallel vertically. A first vertical rod and a second vertical rod are respectively connected to the openings of the first and second U-shaped rods. The B-frame includes a third U-shaped rod and a fourth U-shaped rod, which are also parallel vertically. A third vertical rod and a fourth vertical rod are respectively connected to the openings of the third and fourth U-shaped rods. The first and third vertical rods are hinged, while the second and fourth vertical rods are detachably connected.

[0008] Compared with existing technologies, the auxiliary tool for the hand-push ultrasonic rail flaw detector of this application, through a clamping structure composed of A-frame and B-frame, firmly fixes the hand-push ultrasonic rail flaw detector to the hand-push ultrasonic rail flaw detector, enabling the hand-push ultrasonic rail flaw detector to perform flaw detection on the rails of the column-type integral track bed. This solves the tipping safety hazard of the hand-push ultrasonic rail flaw detector, improves the stability during the flaw detection process, and ensures that the flaw detection operation can be carried out safely. Moreover, during the flaw detection operation, only one person needs to hold the crossbeam to push two hand-push ultrasonic rail flaw detectors forward at the same time, and with the cooperation of two other auxiliary personnel, flaw detection operations can be carried out on both tracks simultaneously. This reduces the number of personnel required for flaw detection operations, frees up labor, and improves flaw detection efficiency.

[0009] As an optimization, in the aforementioned auxiliary tool for the hand-push ultrasonic flaw detector for rails, the crossbeam includes a crossbar A and a crossbar B; the crossbar A is mounted on the third U-shaped bar and abuts against the fourth vertical bar; the crossbar B is mounted on the third U-shaped bar and abuts against the third vertical bar; a pair of fixed rods are provided on the crossbar B, and a U-shaped tie rod is hinged between the fixed rods. With this structure, when performing flaw detection on rails in tunnel-type integral track beds, the U-shaped tie rod can be pulled forward, which is more labor-saving.

[0010] Furthermore, in the aforementioned auxiliary tool for the hand-push ultrasonic flaw detector for rails, a reinforcing rod is provided between the fixed rod and the third vertical rod. The reinforcing rod improves the overall structural strength.

[0011] As an optimization, in the aforementioned auxiliary tool for the hand-push ultrasonic rail flaw detector, the A-shaped crossbar is equipped with a support block, the support block has a U-shaped groove, and the U-shaped groove has a U-shaped rubber pad; when the U-shaped pull rod is placed, it can engage with the U-shaped rubber pad. With this structure, the U-shaped pull rod can be fixed to the support block, facilitating the transfer and storage of the auxiliary tool for the hand-push ultrasonic rail flaw detector.

[0012] As an optimization, the aforementioned auxiliary tool for the hand-push ultrasonic flaw detector for rails includes a pair of rubber sleeves on the A-shaped crossbar. This design allows workers to grip the rubber sleeves and push the device forward, improving grip comfort.

[0013] As an optimization, in the aforementioned auxiliary tool for the hand-push ultrasonic flaw detector for rails, the fourth vertical rod is equipped with an A-thread seat, and the second vertical rod is equipped with a B-thread seat, which are connected by bolts. This detachable connection method facilitates operation and makes installation simple and quick.

[0014] As an optimization, in the aforementioned auxiliary tool for the hand-push ultrasonic flaw detector for rails, the first and third vertical rods are hinged together. This hinged structure facilitates disassembly and allows for replacement if the clamping components are damaged or deformed.

[0015] As an optimization, in the aforementioned auxiliary tool for the hand-push ultrasonic flaw detector for rails, the crossbeam is welded to the clamping assembly.

[0016] Regarding the device, the technical solution of this application is as follows:

[0017] The dual-track ultrasonic flaw detection device includes the aforementioned auxiliary tools for the hand-push type ultrasonic flaw detector and a pair of hand-push type ultrasonic flaw detectors for rails.

[0018] Compared with existing technologies, the dual-track ultrasonic flaw detection device of this application connects two hand-push ultrasonic flaw detectors using an auxiliary tool. This allows the hand-push ultrasonic flaw detectors to perform flaw detection on the rails of the column-type integral track bed, eliminating the tipping safety hazard of the hand-push ultrasonic flaw detectors, improving the stability of the flaw detection process, and ensuring the safe conduct of the flaw detection operation. Furthermore, during flaw detection, only one person needs to hold the crossbeam to simultaneously push the two hand-push ultrasonic flaw detectors forward, and with the cooperation of two other auxiliary personnel, flaw detection can be performed on both tracks at the same time. This reduces the number of personnel required for flaw detection, frees up labor, and improves flaw detection efficiency. Attached Figure Description
