Specifically, the first connector 3 of one track wire groove and the other track wire groove The second connector 4 is installed and matched. In a relatively conventional flat track section, the laying can be completed by directly connecting the two tracks together with a wire groove.

When encountering a track section with a slope, as shown in FIG. 2 , two adjacent track wire grooves have a height difference in the installation position. At this time, as the second wire groove 200 is lifted, the second wire groove of the second wire groove 200 The connecting member 4 drives the first connecting member 3 of the first wire slot 100 , and then drives the second end of the bottom wall 1 connected to the first connecting member 3 to lift upward, so that the bottom wall 1 can form a certain slope. The cables can be laid in a direction passing through the first wire groove 100 and the second wire groove 200 in sequence. It is precisely by virtue of the feature that the bottom wall 1 of the wire groove can form a certain slope, so as to better adapt to the change of the track installation slope, that is, the slope of the bottom wall 1 is generally compatible with the slope of the track section, so that even In the sloped track section, the cable can also be better protected.

The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects: each of two adjacent track wire grooves is connected into multiple segments through the cooperation of the first connecting member 3 and the second connecting member 4, and each track uses a wire The second end of the bottom wall 1 of the groove is configured to be able to be lifted up relative to the first end to form a certain gradient, that is, the bottom wall can be used to form a certain gradient function, so as to better adapt to the change of the track installation gradient and improve the The versatility of the wire slot for the track of the present disclosure is achieved.

According to an embodiment of the present disclosure, as shown in FIG. 3 to FIG. 5 , the first connecting member 3 may be configured as a protrusion, such as a cylindrical protrusion, and the second connecting member 4 may be configured as a roller, and a roller for The plug-in part, for example the second connecting piece 4 , which is plug-fitted with the raised part, can be designed as a hollow pulley. In this way, the first connecting member 3 and the second connecting member 4 can slide up and down between the two adjacent track grooves to meet the requirements of different terrains such as ramps. Optionally, the second end is further provided with a wheel groove 5 along the up-down direction for the roller to roll inside, and the wheel groove has the function of guiding the movement of the roller. Inserting the protruding part into the hollow pulley can realize the fixing of two adjacent rails with wire grooves. After fixing, lift up one of the wire grooves, for example, the second wire groove 200 in FIG. 2 , so that the roller slides up along the wheel groove for lifting, so that the wire groove smoothly enters the uphill of the track.

An elastic member 7 may also be disposed between the second connecting member 4 and the second end of the bottom wall 1 , and the elastic member 7 has an elastic force capable of providing the second end of the bottom wall 1 to move downward. The elastic member 7 can be a compression spring. The function of arranging the elastic member 7 is to make the bottom wall 1 always have a downward tendency to fit the surface of the track, which plays the role of auxiliary fixing. Optionally, the first connector 3 and the second connector 4 are arranged in two groups at intervals along the width direction of the wire groove, the purpose of which is to ensure that the adjacent two rails use the wire groove to have a stable connection, and the process of sliding relatively up and down. is also more stable.

1 and 2 in combination with FIG. 6 , the bottom wall 1 may be configured to include a fixed plate 11 and a movable plate 12 , the fixed plate 11 is fixedly arranged at the bottom of the wire slot, and the first end of the movable plate 12 is connected to the fixed plate 12 . 11 is fixedly connected, the second end of the movable plate 12 is formed as a free end that can be lifted upward, and the second connecting piece 4 is arranged on the free end. In this embodiment, the fixed plate 11 is always in contact with the track, and the movable plate 12 plays a role of forming a certain slope, which will not affect the stability of the installation of the wire groove for the track, and can also meet the requirements of different terrains. .

In addition to having a bottom wall 1 and a side wall 2 , the track wire slot of the present disclosure also includes an arched top wall 6 , one side of the top wall 6 is integrally formed with the side wall 2 , and the other side of the top wall 6 is integrally formed. Openable connection to side wall 2. Optionally, as shown in FIG. 9 , the top wall 6 can be openably connected to the side wall 2 through a lock 10 , and the top wall 6 is designed to be openable for the purpose of maintaining the cables inside the wire slot. The top wall 6 is designed in an arch shape, on the one hand, it can expand more accommodating space, and on the other hand, it can also prevent the vehicle axle counting detection board from being scratched and the wire groove from being lifted. The bottom wall 1 , the side wall 2 and the top wall 6 of the wire slot of the present disclosure can be integrally formed to avoid the problem of warping caused by environmental changes such as thermal expansion and cold contraction. Avoiding the lifting of the wire groove can ensure the safety of the vehicle operation.
