DETAILED DESCRIPTION

[0020] like Figures 1 to 8 As shown, a tunnel illumination detection device disclosed in the present invention comprises a transversely retractable moving vehicle 1 and a transversely retractable tailstock 2 installed on the transversely retractable moving vehicle 1. The transversely retractable tailstock 2 extends in the transverse direction with the extension direction of the tunnel as the longitudinal direction, and the moving front end of the transversely retractable moving vehicle 1 as the head. The transversely retractable tailstock 2 is located at the tail of the entire device. The transversely retractable moving vehicle 1 and the transversely retractable tailstock 2 can shorten their original lengths after retraction. When the device is moved again, it will not interfere with the inner wall of the tunnel, nor will it affect the normal use of the device.

[0021] In some other embodiments, the laterally retractable mobile vehicle 1 includes two partially overlapping support plates, including a fixed support plate and a movable support plate. During retraction, the fixed support plate can be fixed, and the movable support plate can move relatively in the laterally direction. By locking with the locking member 25, the laterally retractable mobile vehicle 1 can be retracted in the laterally direction.

[0022] In the embodiment of the present invention, 7 groups of detection rods 3 are installed on the transverse contraction tailstock 2, corresponding to the positions of the left wall of the tunnel, the left curb, the left traffic center line, the road center line, the right traffic center line, the right curb, and the right wall, respectively. Multiple groups of illumination detectors 4 are evenly spaced and distributed on the detection rods 3; thus, the illumination of the above positions can be detected. The present invention adopts a rectangular grid method, and each section is 5 to 10 meters in each column according to the length of the tunnel in the longitudinal direction, and is evenly divided into the left curb, the left traffic center line, the road center line, the right traffic center line, and the right curb according to the tunnel section in the transverse direction, and a reference value is measured at a height of 2 meters on the left and right walls.

[0023] The seven groups of detection rods 3 are distributed at intervals in the lateral direction of the device and can be preset according to the actual corresponding positions. One end of the detection rod 3 is connected to the lateral contraction tailstock 2, and the other end of the detection rod 3 extends along the longitudinal direction of the device toward a side away from the lateral contraction tailstock 2; in some other embodiments, the seven groups of detection rods 3 are located at the same horizontal height for easy control and adjustment.

[0024] Specifically, the transversely shrinking tailstock 2 disclosed in the present invention includes an inner supporting tail tube 5 installed on the transversely shrinking mobile vehicle 1, and an outer supporting tail tube 6 slidably sleeved on the outside of the inner supporting tail tube 5. The inner supporting tail tube 5 extends in the transverse direction, and the inner diameter of the outer supporting tail tube 6 is adapted to the outer diameter of the inner supporting tail tube 5, thereby allowing the outer supporting tail tube 6 to move along the axial direction of the inner supporting tail tube 5. At the same time, the inner supporting tail tube 5 and the outer supporting tail tube 6 are always coaxial.

[0025] Furthermore, in an embodiment of the present invention, an open groove 7 for making way for the detection rod 3 is provided on the inner supporting tail tube 5 and the outer supporting tail tube 6, and a plurality of groups of sliding columns 8 are provided on the inner sides of the inner supporting tail tube 5 and the outer supporting tail tube 6, some of the sliding columns 8 are fixedly installed in the inner supporting tail tube 5, the sliding columns 8 are connected one-to-one with the detection rod 3, and an elastic supporting device 9 is connected between two adjacent sliding columns 8; the elastic supporting device 9 adopts a spring with the same elastic coefficient, and the two ends of the spring are respectively fixedly connected to the two adjacent sliding columns 8, and the inner side of the outer supporting tail tube 6 is threadedly connected with a compression column 30, and the compression column 30 is located at the end away from the inner supporting tail tube 5.

[0026] When specifically controlling the compression column 30, the compression column 30 is rotated so that the compression column 30 is displaced toward the end where the inner supporting tail pipe 5 is located, and the compression column 30 compresses the sliding column 8. The sliding column 8 acts on other sliding columns 8 through the action of the elastic support device 9, so that they can be displaced synchronously, which is convenient for adjustment. The elastic support device 9 is connected between the sliding columns 8 connected to the detection rod 3 to ensure the consistency of the elastic force of the elastic support device 9, so that the detection rods 3 can always maintain the same interval, thereby facilitating the unified adjustment of the positions of the detection rods 3 at the same time. Of course, the positions of two adjacent detection rods 3 can be set as needed by changing the length and elastic coefficient of the corresponding elastic support device 9, which can be understood by those skilled in the art.

[0027] In this embodiment, a central guide column 10 is fixed at the center of the compression column 30, and a guide hole 11 is opened at the center of the sliding column 8 to cooperate with the central guide column 10. The length of the central guide column 10 is longer than the length of the outer support tail tube 6, but is definitely shorter than the overall length of the transverse contraction tailstock 2. When the compression column 30 is moved, the central guide column 10 can move together, and the central guide column 10 can guide the sliding column 8 in the outer support tail tube 6, reducing the possibility of the sliding column 8 getting stuck when moving.

[0028] In this embodiment, the detection rod 3 includes a hard tube 12 and a flexible telescopic tube 13. Four groups of hard tubes 12 and three groups of flexible telescopic tubes 13 are arranged at staggered intervals along the axial direction of the detection rod 3. Different numbers of hard tubes 12 and flexible telescopic tubes 13 can be selected according to the actual number of illumination detectors 4. By installing the illumination detector 4 on the hard tube 12, the stability during measurement can be ensured. The flexible telescopic tube 13 adopts a rubber bellows, and the hard tube 12 closest to the side of the lateral contraction tailstock 2 is fixedly connected to its corresponding sliding column 8, and the hard tube 12 is slidably arranged in the open groove 7; the hard tubes 12 of each group of detection rods 3 located in the same lateral direction are grouped as one group, and the same group of hard tubes 12 are connected by a lateral contraction rod 14, and the lateral contraction rod 14 is connected to the vertical displacement control component.

[0029] In some other embodiments, the detection rod 3 may also be arranged in a fully flexible telescopic bellows, so that it can be telescoped along the entire axial direction. This embodiment adopts this method, and by setting a hard tube 12, it can be connected to the lateral contraction rod 14 or the illumination detector 4, and the connection is more stable.

[0030] In this embodiment, the vertical displacement control assembly includes a vertical rail 15, a vertical telescopic device 16 installed on the inner side of the vertical rail 15, a transverse retractable rod 14 slidingly cooperates with the vertical rail 15, and the output end of the vertical telescopic device 16 is connected to the transverse retractable rod 14. The vertical telescopic device 16 adopts a hydraulic cylinder, which can drive the transverse retractable rod 14 to move up and down, thereby adjusting the detection height of the illumination detector 4 at this position to meet the illumination detection requirements of tunnels with different slopes. The vertical rail 15 of this embodiment has a vertical groove, so that the end of the transverse retractable rod 14 can slide into it. Both ends of the transverse retractable rod 14 are installed with corresponding vertical rails 15, which can make the movement balance of the device better.

[0031] In this embodiment, the lower end of the vertical track 15 is slidably arranged on the horizontal track 17 installed on the transverse contraction moving vehicle 1, and a longitudinal contraction control component is installed between two adjacent rigid tubes 12. The distance between the two adjacent rigid tubes 12 can be adjusted by the longitudinal contraction control component to meet the requirements of different illumination detection positions.

[0032] In this embodiment, the longitudinal contraction control assembly includes a longitudinal telescopic device 18 fixed on the rigid tube 12, a limiting track 20 is installed on the adjacent rigid tube 12, the limiting track 20 is fixedly installed on one side of the rigid tube 12, and the output end of the longitudinal telescopic device 18 is connected to a sliding sleeve 19, and the sliding sleeve 19 is installed in the limiting track 20 along the vertical sliding direction. Since the rigid tube 12 can move both longitudinally and vertically, the embodiment of the present invention provides a sliding sleeve 19 that can slide vertically, so that the position of the sliding sleeve 19 can be adjusted in the longitudinal direction, and the sliding sleeve 19 will not interfere with the rigid tube 12 in the vertical direction. The vertical and longitudinal movements are independent of each other, which is convenient for control.

[0033] In some other embodiments, the longitudinal contraction control assembly may also be a hydraulic cylinder, and both ends of the hydraulic cylinder are respectively connected to two adjacent groups of vertical rails 15. The extension and retraction of the detection rod 3 is controlled by controlling the movement of the vertical rails 15.

[0034] In this embodiment, the transverse contraction rod 14 includes an outer rod 21, an inner rod 22 slidably mounted on one end of the outer rod 21, and a slide groove 23 is correspondingly provided on the inner rod 22 and the outer rod 21. A sliding shaft 24 corresponding to the slide groove 23 is installed on the detection rod 3, and the sliding shaft 24 and the outer rod 21 and the sliding shaft 24 and the inner rod 22 are connected by a locking member 25. The slide grooves 23 on the inner rod 22 and the outer rod 21 correspond to each other, thereby facilitating the sliding shaft 24 to pass through. The locking member 25 can be a nut threadedly connected to the sliding shaft 24. After the relative position between the inner rod 22 and the outer rod 21 is changed, the two can be fixed by the locking member 25.

The left vehicle body 26 is provided with a limit groove 29 that is slidably matched with the right vehicle body 27. The left vehicle body 26 and the right vehicle body 27 are connected by a locking member 25. When retracting, the left vehicle body 26 is fixed, and the right vehicle body 27 is slid so that the right vehicle body 27 is deeply inserted into the left vehicle body 26. After being locked by the locking member 25, the vehicle body can be retracted. In the embodiment of the present invention, the left vehicle body 26 and the right vehicle body 27 each include two parallel mounting plates and pillars 31 connecting the mounting plates. The two mounting plates on the left vehicle body 26 are not only provided with the limit groove 29, but also provided with a notch 32 for the pillars 31 of the right vehicle body 27 to make way, so as to realize the rapid retraction function of both.

Corresponding maintenance measures are taken for the brightness of the operating tunnels. Among them, in the tunnel mileage, "K1" represents the position of 1 kilometer, "K2" represents the position of 2 kilometers, and "K3" represents the position of 3 kilometers, which should be understandable to those skilled in the art. "K1+200" means starting from the starting point, at the position of 1 kilometer and 200 meters, and so on.
