The above constitutes the basic structure of the present invention.

[0033] The mounting rod 4 of the present invention is installed at the position where the robot needs to turn, and the track-changing section track 6 is rotatably arranged on the mounting rod 4, so that the two ends of the track-changing section track 6 can be respectively connected with the exit track 1 and the entry track 3. The function of the trigger rod 2 is to drive the support rod 5 to move when the robot is triggered, so that under the action of the support rod 5 being limited on the mounting rod 4, the track-changing section track 6 can be driven to rotate, thereby achieving the effect of track changing. The track-changing mechanism adopts a pure mechanical transmission method to achieve track changing, and the track-changing process has no delay, which is equivalent to the time taken for direct passage, and the track-changing efficiency is high. At the same time, the track-changing mechanism is small in size and simple in structure. It can be installed at the position where turning is required, takes up very little space, and is easy to install, simple to disassemble, and has a low manufacturing cost. The use of this track-changing mechanism can save the expensive cost of robot modification and reduce the line inspection cost.

[0034] More specifically, the track section track 6 adopts a linear structure, a bearing 9 is provided at the center of the bottom of the track section track 6, and the track section track 6 is rotatably arranged on the top of the mounting rod 4 through the bearing 9. With such a structural arrangement, under the action of the bearing 9, the track section track 6 can achieve the purpose of rotating on the mounting rod 4.

[0035] More specifically, one end of the track-changing section track 6 is formed with a track-changing section track head end 60, and the other end of the track-changing section track 6 is formed with a track-changing section track terminal 61, the track-changing section track head end 60 is arranged corresponding to the entry track terminal 30 at one end of the entry track 3, and the track-changing section track terminal 61 is arranged corresponding to the exit track head end 10 at one end of the exit track 1. With such a structural arrangement, when the track-changing section track head end 60 is arranged corresponding to the entry track terminal 30 at one end of the entry track 3, the robot can move from the entry track 3 to the track-changing section track head end 60, and when the track-changing section track terminal 61 is arranged corresponding to the exit track head end 10 at one end of the exit track 1, the robot can move from the track-changing section track terminal 61 to the exit track 1.

[0036] More specifically, the bearing 9 is symmetrically provided with mounting parts 8 and baffles 7 hinged to the trigger rod 2 on both sides, and the baffles 7 are arranged on the outside of the mounting parts 8. With such a structural arrangement, the trigger rod 2 is easily installed through the mounting parts 8, and the trigger rod 2 is positioned on both sides of the bearing 9 (i.e., both sides of the mounting rod 4). The baffles 7 are used to position the track-changing section track 6 when the track-changing section track 6 rotates to dock with the exit track 1 or the entry track 3, so as to avoid the track-changing section track 6 not being properly docked when docking with the exit track 1 or the entry track 3.

[0037] More specifically, the mounting member 8 includes a mounting member 1 80 and a mounting member 2 81, and the trigger rod 2 includes a trigger rod 1 20 and a trigger rod 21, wherein the trigger rod 1 20 is hinged to the mounting member 1 80, and the trigger rod 21 is hinged to the mounting member 2 81. With such a structural arrangement, when the robot moves from the track-changing section track 6 to the direction of the entry track 3, the rotation of the track-changing section track 6 is controlled by touching the trigger rod 1 20, and when the robot moves from the track-changing section track 6 to the direction of the exit track 1, the rotation of the track-changing section track 6 is controlled by touching the trigger rod 2 21.

[0038] More specifically, the baffle 7 includes baffle 1 70 and baffle 2 71, wherein baffle 1 70 is arranged corresponding to the entry track 3, and baffle 2 71 is arranged corresponding to the exit track 1. With such a structural arrangement, when the track-changing segment track 6 is docked with the entry track 3, baffle 1 70 serves to limit the entry track 3, thereby achieving accurate docking of the track-changing segment track 6 with the entry track 3, and when the track-changing segment track 6 is docked with the exit track 1, baffle 2 71 serves to limit the exit track 1, thereby achieving accurate docking of the track-changing segment track 6 with the exit track 1.

[0041] More specifically, one end of the support rod 5 is connected to the trigger rod 2, and the other end of the support rod 5 is provided with a strip groove. The mounting rod 4 is provided with a limiting bolt 40, and the limiting bolt 40 is arranged in the strip groove. The support rod 5 can slide a certain distance through the strip groove to be limited on the mounting rod 4.

[0042] More specifically, the support rod 5 includes a support rod 1 50 and a support rod 2 51 . The support rod 1 50 is connected to the trigger rod 1 20 , and the support rod 2 51 is connected to the trigger rod 21 .

[0043] Working principle of the present invention:

[0044] In the initial state, if Figure 3 As shown, the entry track end 30 of the entry track 3 and the track change track head end 60 of the track change track 6 are in a docking state, and the robot takes the entry track 3 as the starting position, as shown in FIG. Figure 4 As shown, at this time, the limiting bolt 40 is just set at the position of the first end 100 of the strip groove of the support rod 50. The robot moves along the entry track 3 to the track change track 6. When the robot touches the trigger rod 20, the upper part of the trigger rod 20 is tilted to the right by the thrust of the robot. Figure 5 As shown, the lower part of the trigger rod 20 pulls the support rod 50 to the left until the limiting bolt 40 is just located at the end 200 of the strip groove of the support rod 50. Figure 6 and Figure 7 As shown, the upper surface of the trigger rod 1 20 is flush with the upper surface of the track section track 6. At this time, the robot can continue to move forward until the robot touches the trigger rod 21. Figure 8 As shown, the first end 100 of the strip groove of the second support rod 51 abuts against the limiting bolt 40, and the second trigger rod 21 will not tilt to the right. Under the continuous action of the driving thrust of the robot, as shown in FIG. Fig. 9 As shown, the track section track 6 starts to rotate until the baffle 2 71 contacts the bottom of the exit track 1, and then stops rotating. During the process from the rotation to the stop of the track section track 6, the following states will appear:

[0045] 1) The entry track end 30 of the entry track 3 and the track change track head end 60 of the track change track 6 will be in a state of slowly disconnecting from the docking;

[0046] 2) During the rotation of the track section track 6, the position of the track section track 6 and the mounting rod 4 is changed, the trigger rod 20 and the support rod 50 are changed, and the limiting bolt 40 on the mounting rod 4 is at the end 200 of the bar groove of the support rod 50 before the track section track 6 rotates. During the rotation of the track section track 6, the head end 100 of the bar groove of the support rod 50 will move toward the position of the limiting bolt 40 until the track section track 6 stops rotating, and the head end 100 of the bar groove of the support rod 50 just contacts the limiting bolt 40;

[0047] 3) During the rotation of the track section track 6, the position of the track section track 6 and the mounting rod 4 is changed, the trigger rod 21 and the support rod 2 51 are changed, the support rod 2 51 always contacts the limiting bolt 40, the upper part of the trigger rod 21 slowly tilts to the left, and the lower part of the trigger rod 21 pushes the support rod 2 51 to the right, until the track section track 6 stops, the upper surface of the trigger rod 21 is flush with the upper surface of the track section track 6, and the robot can continue to move forward;

[0048] 4) The end 61 of the track change section track 6 and the head end 10 of the exit track 1 are slowly connected from the disconnected state;

[0049] The track-changing action of the horizontal track-changing mechanism dedicated to the track-type inspection robot described above has the same working principle when the robot returns.

[0050] The technical solutions in the embodiments of the present invention are described above, but the present invention is not limited to the above-mentioned specific implementation modes. The above-mentioned specific implementation modes are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present invention and the claims, which all belong to the protection scope of the present invention.
