[0002] Road and bridge safety inspection is an important step in road and bridge construction. In order to protect the safety of pedestrians around during the construction process, safety inspection devices need to be used to ensure safety during construction. However, existing safety inspection devices still have some defects when used.

When in use, the above-mentioned device buffers the camera shooting at the bridge, thereby facilitating the staff to observe the road conditions; however, during the construction process, the firmness of the installation of the construction fence cannot be tested. When pedestrians walk under the bridge, the construction fence that is not firmly installed will fall off and cause serious safety accidents.

[0021] (III) Beneficial effects

[0022] The road and bridge safety detection device and detection method provided by the present invention have the following beneficial effects:

[0023] 1. Through the flatness detection component, the device can observe the ups and downs of the connecting blocks at various positions through the camera during the movement. The ball bearings under the connecting blocks can reduce the resistance of the connecting blocks when they move, and the connecting blocks can realize the function of self-adapting to the high and low undulating ground when they contact the ground through the ball bearings. The ups and downs of the tops of the connecting blocks at various locations simulate the ups and downs of the ground, so that the device can understand the ups and downs of the ground during the movement, which solves the defect that the existing road and bridge safety detection devices cannot intuitively understand the degree of ground ups and downs. In addition, the device can also adjust the height of the control plate on the display so that the device can compare the content displayed on the display through the control plate. If a connecting block exceeds the control plate, the surface ups and downs are too large, thereby changing the allowable error range of the ground ups and downs;

[0024] 2. Through the setting of the clamping assembly and the firmness test assembly, the device can, after clamping the enclosure on the bridge, push the second electric push rod through the first electric push rod, so that the device can push the movable rod to the right, so that the device can squeeze the construction enclosure through the outer bushing, so that the device can test the firmness of the enclosure after clamping the enclosure. In conjunction with the traction steel rope, transmission assembly and alarm, the device can make the traction steel rope continue to pull the convex plate to the right during the gradual extension of the first electric push rod, so that the device can change the strength of the firmness test, thereby improving the adjustability of the device. In addition, in the process of the outer bushing gradually moving to the right, the meshing transmission structure can be used to gradually bring the first conductive contact piece and the second conductive contact piece closer to each other, so that the outer bushing can automatically trigger the alarm light when the connection of the enclosure is pushed and separated, so that the staff can re-secure the enclosure that has fallen off. The device can test the firmness of the enclosure while ensuring that the enclosure in the construction area will not fall off the edge of the bridge, thereby improving the functionality and applicability of the device and solving the problem that the existing road and bridge safety detection device cannot perform firmness testing while ensuring that the enclosure will not fall off during use;

[0025] 3. By setting up rubber drums distributed at equal intervals, the rubber drums can maintain a certain resistance when clamping the enclosure, so that the enclosure will not fall off, and the first spring and the connecting shaft enable the device to fix enclosures of different sizes, and in the process of fixing the enclosure, the inverted cone structure at the bottom of the enclosure can also be utilized, so that the first electric push rod on the device can automatically clamp the enclosure when moving downward, and the rubber drum can also clamp without affecting the forward and backward movement of the device, thereby improving the use effect of the device.

[0050] Embodiment 3:

[0051] The schemes in Example 1 and Example 2 are further introduced below in combination with specific working methods, as described below for details:

[0052] Specifically, when the road and bridge safety detection device and detection method are used:

[0053] like Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, during the use of the device, the flatness of the ground is tested by the flatness detection assembly 5. The flatness detection assembly 5 is first unfolded, and the clamping rod 12 in the docking plate 11 is pulled out so that the docking rod 14 and the first connecting plate 501 can rotate on the support seat 1, and the flatness detection assembly 5 is rotated to Figure 5At this time, the connection frame 504 naturally falls inside the first connection plate 501 through the limit rod 503, and contacts the ground through the balls 509 on the fixed blocks 508 at various locations in the connection frame 504, so that when the device moves, the fixed blocks 508 will not be worn due to excessive friction. At the same time, the camera 502 on the first connection plate 501 will shoot and record the ups and downs of the connection blocks 505 at various locations in the connection frame 504. Since the balls 509 contact the ground, the connection blocks 505 will move through the movable grooves 506 and the connection blocks 507 at the connection blocks 505 at the adjacent positions. The device moves up and down on the connecting block 505, so the ups and downs of the connecting blocks 505 at various locations in the connecting frame 504 are the ups and downs of the ground. By using the cameras 502 arranged at equal intervals and the connecting blocks 505 evenly distributed, the device can timely display the ground ups and downs of various areas of the current road surface through the display screen 3, so that the detection accuracy of the device is higher, and the area with excessive ups and downs can be re-trimmed. The device can display the ups and downs of the connecting blocks 505 at various locations on the display screen 3 through the camera 502, and then change the height of the control plate 18 through the damping rod 17 on the side connecting block 16 (combined with Fig. 9 As shown), observe whether the connecting block 505 exceeds the control plate 18, and perform control detection work by the control plate 18 at different heights, so that the device can change the allowable range of road surface undulation error;

[0054] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the device can also detect the firmness of the construction fence 15 during the movement. The construction fence 15 is first clamped by the clamping assembly 7, and the second electric push rod 13 and the supporting plate 703 are moved vertically to the bottom of the folding plate 4 through the guide rod 701 by extending the first electric push rod 702. The inverted truncated cone structure under the rubber rotating cylinder 706 enables the two sets of rubber rotating cylinders 706 to be automatically clamped on the left and right sides of the construction fence 15. At this time, the rubber rotating cylinder 706 is clamped by the first spring 70 9 and the connecting shaft 707 move under the supporting plate 703, and the slider 704 exerts a pulling force on the first spring 709 between the overlapping blocks 708, so that the two adjacent rubber drums 706 can clamp the construction fence 15 without affecting the forward and backward movement of the device as a whole; during the extension of the first electric push rod 702, the traction steel rope 10 on the left side of the second electric push rod 13 can cooperate with the guide wheel to pull the convex plate 802, so that the convex plate 802 drives the movable rod 801 and the extension rod 803 to move to the right The outer bushing 805 of the device is moved, thereby enabling the device to push the outer bushing 805 through the second spring 804, so that the outer bushing 805 can squeeze the construction fence 15 to the right, so that the device can test the firmness of the fence docking position, and the greater the extension of the first electric push rod 702, the longer the distance the extension rod 803 moves to the right, the higher the compression degree of the second spring 804, and therefore the greater the test force, thereby adjusting the test force of the device on the firmness of the fence; when the outer bushing 805 of the device pushes the construction fence 15 to be detached or deformed, the first rack 901 moves to the right, the gear 902 on the cross plate 904 rotates counterclockwise, and the second rack 903 drives the slide frame 604 to move to the left, thereby driving the battery 605 and the second conductive contact 606 to move to the left, until the second conductive contact 606 contacts the first conductive contact 603, at which time the alarm light 602 is energized, so that the construction fence 15 on the device can automatically light up when it is pushed to be detached or deformed, thereby realizing the automatic alarm function.
