Description

Technical Field

[0001] The utility model relates to the field of broken rail search tools, in particular to a rail crack search device. Background Art

[0002] From the recent rail official departments and the whole-railway broken rail cases, during the emergency disposal of broken rails, the situation of emergency overtime often occurs due to the long disposal time. Especially after entering the critical period of anti-breaking, at night the temperature is low, and under low temperature conditions, the rail bears huge tensile stress, resulting in the vast majority of broken rails occurring at night. The current technical means can only see the red light band section and cannot directly find the specific broken rail position. It is necessary to manually check the entire red light band section on foot. Due to insufficient light at night and the poor mental state of personnel, it is difficult to find the crack position. Especially for smaller cracks, it is very difficult to distinguish them with the naked eye. There are situations where the crack is searched back and forth on the site or not found at all, which is very time-consuming in searching for the crack. Although each workshop of the rail official department also has simple broken rail search tools, the design is not particularly standardized. First, it cannot effectively search for irregular cross-sections and is prone to missing cracks. Second, it is difficult to push the existing searcher in places with more fish scale patterns. Third, the existing searcher has a bamboo pole handle, which is not easy to store and is prone to damage. Content of the Utility Model

The probe assembly includes a probe sleeve. The probe sleeve is arranged on the base. A probe is arranged inside the probe sleeve. A stop spring is arranged above the probe. A top screw is arranged above the stop spring.

[0006] Further, the push handle is arranged obliquely.

[0007] Still further, a first mounting hole matching the probe sleeve is arranged on the top surface of the base. A second mounting hole matching the push handle is arranged on one side of the base.

[0008] Still further, a third mounting hole is arranged on the bottom surface of the base.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] As Figure 1-7As shown in the figure, a device for detecting rail joint breaks includes a base 1. Above the base 1, a push handle 2 is installed. In the middle of the base 1, a probe assembly 3 is installed. The probe assembly 3 includes a probe sleeve 3-1. The probe sleeve 3-1 is installed on the base 1. Inside the probe sleeve 3-1, a probe 3-2 is installed. Above the probe 3-2, a stop spring 3-3 is installed. Above the stop spring 3-3, a set screw 3-4 is installed.

[0022] Specifically, the material of the base 1 is nylon, which is convenient for being light and flexible. Considering the influence of the rail web, the internal dimensions of the groove of the base 1 are appropriately widened.

[0023] On the top surface of the base 1, a first mounting hole 1-1 matching the probe sleeve 3-1 is provided. On the outer wall of the probe sleeve 3-1, there is a thread, and on the inner wall of the first mounting hole 1-1, there is a matching thread. The probe sleeve 3-1 is threadedly connected in the first mounting hole 1-1. In this embodiment, two first mounting holes 1-1 are provided, and the two first mounting holes 1-1 are arranged side by side. On both sides of the rail 5 are the non-working edge 5-1 of the rail and the working edge 5-2 of the rail respectively. The non-working edge 5-1 of the rail does not contact the train wheels and has a smooth surface. During the long-term operation of the working edge 5-2 of the rail, wear will occur and the surface will be uneven. If the probe moves on this side, misjudgment is likely to occur. Considering the smoothness of the surface of the rail 5 and various damage conditions to avoid misjudgment, the probe assembly 3 is always installed on the side close to the non-working edge 5-1 of the rail. When the staff pushes the base 1 to move in different directions, in order to ensure that the probe assembly 3 is always installed on the side close to the non-working edge 5-1 of the rail, the first mounting hole 1-1 on the side close to the non-working edge 5-1 of the rail can be selected according to needs to install the probe assembly 3.

[0024] On one side of the base 1, a second mounting hole 1-2 matching the push handle 2 is provided. The push handle 2 is inclined and installed in the second mounting hole 1-2. Specifically, the second mounting hole 1-2 has a certain depth, and during actual use, the height of the push handle 2 can be adjusted according to the height of the staff.

[0025] On the bottom surface of the base 1, a third mounting hole 1-3 is provided. A magnet 4 is installed in the third mounting hole 1-3. In this embodiment, the number of the third mounting holes 1-3 is set to two. During actual use, under the magnetic force of the magnet 4, the bottom surface of the base 1 is always attached to the surface of the rail, so that the probe can better detect the joint break and prevent the base 1 from lifting, and the probe 3-2 cannot detect the existence of the joint break.

[0026] In this embodiment, the probe 3-2 is truncated with a standard needle having a certain rigidity.

[0027] The inside of the probe sleeve 3-1 is provided with a receiving hole matching the stop spring 3-3. A small hole through which the tip of the probe 3-2 can pass is provided at the bottom of the receiving hole. Threads matching the setscrew 3-4 are provided on the inner wall of the probe sleeve 3-1. The setscrew 3-4 is threadedly connected to the probe sleeve 3-1. By pressing the stop spring 3-3 with the setscrew 3-4, the stop spring 3-3 applies a downward force to the probe 3-2. Under normal circumstances, the probe 3-2 contacts the top surface of the rail 5. When encountering a broken joint, under the action of the force of the stop spring 3-3, the probe moves downward and inserts into the broken joint.

[0028] The using process of the utility model is as follows:

[0029] When a rail break occurs, the operator pushes the push handle 2 to search on the line. When encountering a broken joint, under the action of the stop spring 3-3, the tip of the rigid probe 3-2 can insert into the broken joint. At this time, the operator feels the pushing resistance and judges the existence of the broken joint, achieving the purpose of quickly searching for the broken joint.

[0030] In another embodiment, as Figure 7 shown, a lock nut 6 is threadedly connected to the outside of the probe sleeve 3-1. The lock nut 6 locks the position of the probe sleeve 3-1. The bottom surface of the lock nut 6 contacts the top surface of the base 1. During the adjustment after the probe wears, when the steel needle wears, rotate the probe sleeve 3-1 to move the whole probe assembly downward, and then use the lock nut 6 to lock the position of the probe sleeve 3-1.

[0031] The embodiments described above are only used to describe the preferred mode of the utility model, and do not limit the scope of the utility model. Without departing from the design spirit of the utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the utility model shall fall within the protection scope determined by the claims of the utility model.
