Description

Technical Field

[0001] The utility model relates to the technical field of track detection, in particular to a portable non-destructive detection device for intercity trains. Background Art

[0002] The construction of intercity trains has made public transportation more convenient. Intercity trains run on steel rails. For the safety of intercity trains, the rails need to be inspected regularly to ensure the safety of train operation.

[0003] In the related art, a search revealed a scheme of a portable nondestructive testing device for intercity trains (Announcement No. CN213209957U), which can facilitate movement and carrying by setting up components such as an X-ray detection head, an outer rod, an inner rod and moving wheels, thereby reducing the burden on users. The X-ray detection head is used to perform nondestructive testing on the position that needs to be inspected. When moving, the outer rod is turned out, and the inner rod can be adjusted according to the needs of the user. The inner rod is pulled and the moving wheels are used to facilitate movement and carrying, thereby reducing the burden on users.

[0004] However, although the above-mentioned method of using a cart to move the non-destructive testing device has certain conveniences, the road conditions where the rails are laid are complicated. When pushing the non-destructive testing device to move, if the ground is uneven, it is more laborious and troublesome, and the detection is not convenient enough. During the detection, it is also necessary to hold the X-ray detection head for detection. During continuous detection, it is inconvenient to monitor while moving, and the detection efficiency is not high enough. Utility Model Content

[0005] The purpose of the utility model is to provide a portable non-destructive testing device for intercity trains to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable nondestructive testing device for intercity trains, comprising a casing, an extension rod is inserted into the casing, a handle is provided at the right end of the casing, an extension rod is inserted into the casing, the extension rod can be extended and retracted in the casing, and is convenient to carry when not in use, an ultrasonic probe is installed on the surface of the extension rod, a flaw detection host is installed on the casing, and the flaw detection host is electrically connected to the ultrasonic probe;

[0007] A roller is installed on the lower surface of the extension rod, a bracket is connected to the surface of the extension rod, and an auxiliary wheel corresponding to the roller is installed on the bracket. The roller and the auxiliary wheel can move stably on the rail, which is convenient for the non-destructive testing device to move and test at the same time;

[0008] The left and right sides of the bracket are both screwed with adjustment handles, and one end of the adjustment handle is equipped with a universal ball. When the universal ball presses against the rail, the nondestructive testing device can be prevented from tilting.

[0009] Furthermore, a fixed shell is fixedly connected to the surface of the extension rod, the ultrasonic probe is inserted into the fixed shell, a rotating seat is installed on the upper surface of the sleeve, an elastic clip is installed on the rotating seat, and the flaw detection host is placed inside the elastic clip. The ultrasonic probe and the flaw detection host can be removed and put away when not in use.

[0010] Furthermore, a buffer is installed at one end of the adjustment handle, and the universal ball is connected to the end of the buffer. The buffer has a buffering effect on the universal ball. When the side of the rail is uneven, the buffer can be extended and retracted to prevent the universal ball from being stuck on the side of the rail.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The casing and the extension rod can be moved along the rails by means of rollers and auxiliary wheels. The overall structure is more advanced and can be carried by one person, thereby driving the ultrasonic probe to move along the rails for detection. This not only improves the detection efficiency of the rails, but also saves effort in pushing the ultrasonic probe forward, making it easy to operate.

[0013] (2) The two universal balls support the rails and provide support for the extension rod. When the handle is not held, the extension rod can be prevented from falling on the rails, preventing the flaw detector from falling to the ground, making it safer to use.

[0014] (3) The flaw detection host and ultrasonic probe can be disassembled and used, not limited to the inspection of rails, but also for the inspection of other supporting equipment of intercity trains. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] An extension rod 2 is inserted into the casing 1, and an ultrasonic probe 5 is installed on the surface of the extension rod 2. The ultrasonic probe 5 is suspended above the rail and can detect flaws in the rail. A flaw detection host 12 is installed on the casing 1, and the flaw detection host 12 is electrically connected to the ultrasonic probe 5. The flaw detection host 12 is located on the upper part of the casing 1, which is convenient for the staff to view the data displayed by the flaw detection host 12;

[0023] A roller 6 is installed on the lower surface of the extension rod 2, a bracket 7 is connected to the surface of the extension rod 2, an auxiliary wheel 8 corresponding to the roller 6 is installed on the bracket 7, and the roller 6 cooperates with the auxiliary wheel 8 to improve the stability of the non-destructive testing device moving on the rail;

[0024] The left and right sides of the bracket 7 are both screwed with adjustment handles 9, and one end of the adjustment handle 9 is installed with a universal ball 14. When the left and right universal balls 14 are against the rail, the sleeve 1 and the extension rod 2 are prevented from tilting.

[0025] In this embodiment, if Figure 1 As shown, a fixed shell 4 is fixedly connected to the surface of the extension rod 2, and the ultrasonic probe 5 is inserted into the fixed shell 4. The fixed shell 4 can clamp and fix the ultrasonic probe 5, and the ultrasonic probe 5 can be removed from the fixed shell 4.

[0026] In this embodiment, if Figure 1 As shown, a rotating seat 10 is installed on the upper surface of the sleeve 1, and an elastic clamp 11 is installed on the rotating seat 10. The flaw detection host 12 is placed inside the elastic clamp 11. The rotating seat 10 allows the elastic clamp 11 to rotate, thereby adjusting the viewing angle of the flaw detection host 12.

The buffer 16 can be extended and retracted. When the universal ball 14 is against the rail and moves along the rail, if the rail is uneven, the buffer 16 can move the universal ball 14 to ensure that the universal ball 14 will not be stuck by the rail.

[0030] Specifically, when in use, the roller 6 and the auxiliary wheel 8 are placed on the rail, and the adjusting handle 9 is turned so that the adjusting handle 9 pushes the universal ball 14 to support the rail, so that the sleeve 1 and the extension rod 2 will not tilt left or right, and the roller 6 and the auxiliary wheel 8 are pushed to move on the rail through the handle 13. The ultrasonic probe 5 detects the rail as the extension rod 2 moves, and the data displayed by the flaw detection host 12 is checked at the same time, so that the rail detection can be realized. The whole structure is light and simple, convenient to carry, and easy to use.
