Description

Technical Field

[0001] The utility model relates to the technical field of corridor inspection robots, in particular to a corridor track system used for robot inspection. Background Art

[0002] The cushion pond and the second dam are important components of the hydropower station. The second dam, as the name implies, is the "second dam" relative to the main dam. It is located at a certain distance downstream of the main dam. The cushion pond is formed by building the second dam downstream. The cushion pond and the second dam together constitute the flood discharge and energy dissipation structure of the dam. The cushion pond and the second dam corridor are passages located inside the cushion pond and the second dam buildings, providing a passage for staff to enter the dam body for inspection, observation and maintenance, and are also used to collect seepage from the dam body and the dam foundation. The corridor environment is complex, the corridor is less than two meters high, and the width is only enough for two people to pass side by side. The corridor route is a mesh structure and is relatively long. In addition, there are many uncertain factors such as wall leakage, ground water accumulation, and harmful gas accumulation, which often lead to the lack of safety guarantees for staff entering the corridor.

[0003] With the continuous development of science and technology, inspection robots have gradually been widely used in various fields, especially in the power, railway, tunnel and other industries. Inspection robots have become an important means of modern inspection with their advantages of high efficiency, accuracy and safety. At present, inspection robots are also used to enter the corridor for inspection. When the inspection robot conducts inspection in the corridor, it walks along the track built in the corridor. This track is built on the top surface of the corridor, and the inspection robot walks on the track. Before the robot conducts inspection, it is necessary to conduct corresponding project tests on the robot walking on this track, such as rotary turnout function test, climbing test and track connection strength test. Due to the complex on-site environment of the corridor, the turning point and the climbing point are far apart. If the inspection robot is tested on-site, it is difficult to test all the items at one time. In addition, the experimental base is far away from the water cushion pond of the hydropower station and the Erdaoba corridor. It takes a lot of time to test back and forth, which increases the time cost and labor cost.

[0004] Therefore, considering factors such as the internal slope, length, and vertical and horizontal intersections of the corridor, a track was simulated for the inspection robot to walk in the corridor, and this track system was set up at the experimental base to conduct corresponding project tests on the inspection robot.

It can be seen from the above structure that the corridor track system includes a track bracket 1, a plurality of straight track modules 2, a rotating turnout module 3 and a ramp track module 4. The track bracket 1 is mainly used to simulate the overall corridor structure in the corridor, and is set up according to the corridor length, slope and vertical and horizontal intersections, and is used to support and fix the track for the inspection robot to walk in the corridor. The walking of the inspection robot in the corridor is mainly divided into horizontal walking, climbing and turning at the intersection of the corridor, so a linear track module 2, a rotary switch module 3 and a slope track module 4 are correspondingly provided, and each module is fixed at the corresponding position of the track bracket 1. The linear track module 2 indicates that the inspection robot walks horizontally on this module, and the two ends of the slope track module 4 are respectively connected to the linear track module 2. The inspection robot enters the slope track module 4 from the linear track module 2 to climb, thereby performing a climbing test, and then enters the linear track module 2 after the end. A rotary switch module 3 is provided at the intersection of the linear track module 2, which is used for the inspection robot to rotate and change tracks when it encounters a crossing of the walking track and needs to turn, thereby performing a rotary switch 13 function test.

The linear track assembly 5 includes a linear track 6 and at least one slot-type connector 7. The inspection robot walks on the linear track 6, and the slot-type connector 7 is used to fix the linear track 6 on the track bracket 1. The linear track 6 of the linear track module 2 is fixed to the track bracket 1 through the groove-shaped connector 7 in a horizontal state, and the track of the ramp track module 4 is fixed to the track bracket 1 through the groove-shaped connector 7 in an inclined state. Figure 1 The square frame bracket 23 shown in the figure fixes the slot-type connector 7 on the square frame bracket 23. By adjusting the distance between the square frame brackets 23 and the height of the square frame bracket 23 on the track bracket 1, the inclination of the linear track 6 of the slope track module 4 can be controlled, so that the extreme climbing ability of the inspection robot can be tested. The top of the slot-type connector 7 is fixed on the track bracket 1, with the slot facing downward, and the ends of the two side walls of the slot-type connector 7 are connected and fixed with a fixing block 8, and the linear track 6 is fixedly connected to the other end of the fixing block 8.

As can be seen from the above structure, the linear track module 2 and the adjacent linear tracks 6 in the ramp track module 4 are connected via the track connector 9. Figure 4 As shown, the track connector 9 is a tubular structure connecting pipe, the diameter of the middle part is larger than the diameter of the two sides, and is the same size as the linear track 6. The diameter of the two sides of the connecting pipe is smaller than the linear track 6, so that the two adjacent linear tracks 6 can be respectively sleeved on both sides of the connecting pipe. The large diameter of the middle pipe is used to limit the linear track 6, and after the connection is completed, the outer edge line of the overall contour is flush, so that the inspection robot can pass smoothly. The linear track 6 is divided into several small sections, and the adjacent sections of the linear track 6 are connected through the track connector 9, making the linear track 6 easier to transport and disassemble.

[0031] The ramp track module 4 also includes a curved track 10; one end of the curved track 10 is connected to the linear track 6 of the ramp track module 4 through a track connector 9, and the other end is connected to the linear track 6 of the linear track module 2 through a track connector 9.

The auxiliary teeth mesh with the gears on the outside of the tires of the inspection robot, which not only prevents the inspection robot from slipping when going uphill, but also enhances the climbing ability of the inspection robot.

[0033] Embodiment three:

[0034] See attached Figures 1 to 6 . On the basis of the second embodiment, the rotating turnout module 3 includes a rotating mechanism 12 and a rotating turnout 13; the rotating mechanism 12 is fixed on the track bracket 1 through a first connecting member 14; a rotating turnout 13 is connected below the rotating mechanism 12; the rotating mechanism 12 is used to drive the rotating turnout 13 to rotate, so that the linear track modules 2 located on the same straight line at the intersection of the linear track modules 2 are connected through the rotating turnout 13. As can be seen from the above structure, the rotating turnout module 3 includes a rotating mechanism 12 and a rotating turnout 13, and the rotating shaft of the rotating mechanism 12 is connected to the rotating turnout 13, which is used to drive the rotating turnout 13 to rotate, so that the linear track modules 2 on the same straight line at the turnout of the linear track modules 2 are connected through the rotating turnout 13. The rotating mechanism 12 is fixed on the track bracket 1 through a plurality of first connecting members 14, and four first connecting members 14 can be arranged around the rotating mechanism 12 to fix it on the track bracket 1. When the inspection robot enters the rotating turnout 13 and rotates with the rotating turnout 13 to change tracks, it can travel to another linear track module 2.

[0035] The rotating switch 13 includes a linear track 6 and a slot connector 7; the slot of the slot connector 7 is downward; fixed blocks 8 are respectively arranged on both sides of the slot; one end of the fixed block 8 is connected to the side wall of the slot connector 7, and the other end is fixed with a linear track 6; the slot connector 7 in the middle of the rotating switch 13 is connected to the rotating shaft of the rotating mechanism 12. As can be seen from the above structure, the switch includes a linear track 6 and a slot connector 7, the top of the slot connector 7 in the middle of the rotating switch 13 is connected to the rotating shaft of the rotating mechanism 12, and a reinforcing steel plate can also be set on the top of the slot connector 7, the reinforcing steel plate is arranged along the setting direction of the slot connector 7 and fixed to the top of the slot connector 7, and the rotating shaft of the rotating mechanism 12 is connected to the reinforcing steel plate. The slot of the slot connector 7 is downward, and the ends of the two side walls are fixed with fixed blocks 8, and the other end of the fixed block 8 is facing the slot of the slot connector 7, and is fixedly connected with the linear track 6.

[0036] A laser beam sensor 15 is provided on the outer side wall of the grooved connector 7 of the rotating turnout 13; the laser beam sensor 15 senses the position of the inspection robot on the rotating turnout 13. As can be seen from the above structure, laser beam sensors 15 are provided on the outer sides of both side walls of the grooved connector 7 of the rotating turnout 13 to sense the progress of the inspection robot entering the rotating turnout 13. When all laser beam sensors 15 sense the inspection robot, it means that the inspection robot has completely entered the turnout, and the next step can be performed.

[0037] The rotary switch module 3 also includes a positioner 16; the positioner 16 includes a travel switch 17 and a first toggle block 18; the first toggle blocks 18 are provided on the grooved connectors 7 at both ends of the rotary switch 13; the grooved connector 7 on the linear track module 2 adjacent to the rotary switch is provided with a travel switch 17; the travel switch 17 cooperates with the first toggle block 18 to determine whether the linear track 6 of the rotary switch 13 is aligned with the linear track 6 of the linear track module 2. As can be seen from the above structure, the positioner 16 is used to ensure that the linear track 6 in the rotary switch is aligned with the linear track 6 in the linear track modules 2 adjacent to the surrounding areas. The grooved connectors 7 in the linear track modules 2 adjacent to the rotating turnout module 3 are all provided with travel switches 17. The travel switches 17 can be CHNT / Chint 8108 travel switches 17. The rotating arm of the travel switch 17 is facing the rotating turnout. The grooved connectors 7 at both ends of the rotating turnout are provided with first toggle blocks 18 that cooperate with the travel switch 17. When the rotating turnout rotates, the first toggle block 18 also rotates accordingly. When the first toggle block 18 rotates to contact the rotating arm of the travel switch 17, it continues to rotate and toggle the rotating arm, and the rotating arm starts to rotate. When the linear track 6 in the rotating turnout rotates and aligns with the linear track 6 in the adjacent linear track module 2, the rotating arm rotates to a fixed angle. At this time, the travel switch 17 sends a stop rotation signal to the rotating mechanism 12, and the rotating turnout stops rotating.

[0038] The rotary turnout also includes a stopper 19; the stopper 19 includes a movable block 20 and a second toggle block 21; the grooved connectors 7 at both ends of the rotary turnout 13 are also provided with a second connector 22; the second connector 22 is provided with a rotatable movable block 20; the grooved connector 7 adjacent to the rotary turnout on the linear track module 2 is provided with a second toggle block 21; the movable block 20 cooperates with the second toggle block 21. As can be seen from the above structure, the stopper 19 is used to control the inspection robot to enter and exit the rotary turnout and ensure that the inspection robot will not slide off the linear track 6 when it rotates with the rotary turnout after entering the rotary turnout. A second connecting piece 22 is provided on the groove-shaped connecting piece 7 at both ends of the rotating turnout 13, and a freely rotatable movable block 20 is provided on the second connecting piece 22. The movable block 20 is facing the linear track module 2. Second toggle blocks 21 are provided on the groove-shaped connecting pieces 7 in the linear track modules 2 adjacent to the rotating turnout module 3. When the linear track 6 in the rotating turnout rotates and is aligned with the linear track 6 in the adjacent linear track module 2, the second toggle block 21 toggle the movable block 20 to rotate to a certain angle, and the inspection robot can smoothly enter the rotating turnout. When the inspection robot completely enters the rotating turnout and the rotating turnout rotates, the second toggle block 21 leaves the movable block 20, and the movable block 20 returns to its original position under the action of gravity, so that the entrance and exit heights at both ends of the rotating turnout 13 can be blocked to ensure that the inspection robot will not fall off the linear track 6 when rotating with the rotating turnout.

[0039] Rotary turnout function test:

[0040] The inspection robot moves from the linear track module 2 to the rotary switch module 3, and the inspection robot sends the number of the linear track module 2 where it is located to the rotary mechanism 12. After receiving the signal, the rotary mechanism 12 drives the rotary switch 13 to rotate, so that the linear track 6 of the rotary switch 13 approaches the linear track module 2 where the inspection robot is located. The positioner 16 determines whether the linear track 6 in the rotary switch and the linear track 6 in the adjacent linear track modules 2 are aligned. After alignment, the movable block 20 of the limiter 19 is rotated and opened under the action of the second toggle block 21, and the rotary mechanism 12 moves to the inspection robot. The robot sends a pass signal and waits for the inspection robot to enter the rotating switch. After receiving the signal, the inspection robot runs to the linear track 6 of the rotating switch 13, and senses the progress of the inspection robot entering the rotating switch 13 through the laser beam sensor 15. When all laser beam sensors 15 sense the inspection robot, it means that the inspection robot has completely entered the rotating switch 13, and the rotating switch 13 begins to rotate. The second toggle block 21 leaves the movable block 20, and the movable block 20 returns to its original position to block the entrance and exit of the rotating switch 13 to prevent the inspection robot from falling when the rotating switch 13 rotates. When the rotating switch 13 rotates to the linear track module 2 that the inspection robot needs to enter, and the linear track 6 of the rotating switch 13 is aligned with the linear track 6 of the linear track module 2, the rotating switch 13 stops rotating. At this time, the second toggle block 21 of the linear track module 2 that needs to be entered pushes away the movable block 20, and the inspection robot can normally drive out of the rotating switch 13 and enter the linear track module 2 that needs to be entered.

[0041] Inspection robot climbing test:

[0042] The inspection robot walks to the lower end of the slope track module 4, passes through the curved track 10, and enters the slope track module 4. The gears on the outer side of the tires of the inspection robot cooperate with the racks on the fixed block 8 to provide power and support for the inspection robot. After the inspection robot finishes going uphill, it passes through the curved track and slowly adjusts to enter the linear track module 2. The inspection robot stops running after receiving the stop signal sent by the tester or touching the baffle at the end of the linear track 6 in the linear track module 2, waiting to receive the next instruction.
