[0042] The sliding gear sleeve column 6 is symmetrically structured and slidably connected to the outside of the guide channel frame 1 , and is transmission-connected to both the limit adjustment rod 4 and the light indicator rod 5 .

[0043] The bridge and culvert height limit reminder device uses the vehicle passing through the guide channel frame 1 to measure and compare with the height limit roller 3 with directional height adjustment. When the vehicle is overheight, the height limit roller 3 is pushed up to limit the position and move upward. The upward-moving height limit roller 3 drives the hingedly installed limit adjustment rod 4, which contracts and flips and is transmission-connected with the sliding gear sleeve column 6, so that the moving sliding gear sleeve column 6 is transmission-connected with the light indicator rod 5 and flips, and the driver is given a light interception indication, thereby improving the use effect of the height limit.

[0045] The bridge and culvert height limit reminder device can reduce the speed of passing vehicles by utilizing the speed reduction belt 12 so as to cooperate with the height limit detection.

[0046] Reference Figure 1 In the bridge and culvert height limit reminder device recorded in the embodiment of the present application, the height limit guide frame 2 is arranged in a U-shaped structure. The height limit guide frame 2 arranged in the U-shaped structure is symmetrically provided with two guide grooves, which can be slidably adapted with the height limit roller 3, and a height mark is provided on the outside of the guide groove.

[0047] The bridge and culvert height limit reminder device utilizes the height limit guide frame 2 to slide and limit the height limit roller 3, so that the height limit roller 3 is lifted and lowered along the track, and the height mark outside the guide groove can realize the fixed height interception adjustment of the height limit roller 3.

[0048] Reference Figure 3 and Figure 1 In the bridge and culvert height limit reminder device recorded in the embodiment of the present application, the height limit roller 3 includes a roller 31. Both ends of the roller 31 made of PE resin are inserted with plug posts 32. The outside of the plug posts 32 is rotatably connected to a sliding rod sleeve 33 by bolts. The sliding rod sleeve 33 is limited to slide and fit outside the guide groove.

[0049] The bridge and culvert height limit reminder device can improve the environmental friendliness of the roller 31 and reduce the cost by using the roller 31 made of PE resin. At the same time, under the support of the sliding rod sleeve 33, the roller 31 can be easily disassembled and replaced.

[0050] Reference Figure 4 and Figure 1 The limit adjustment rod 4 in the bridge culvert height limit reminder device recorded in the embodiment of the present application includes a sliding sleeve 41 hingedly installed on one side of the guide channel frame 1, and a storage rod 42 is slidably connected inside the sliding sleeve 41. The other end of the storage rod 42 is hingedly installed on the side wall of the sliding rod sleeve 33, and a distance sleeve 43 that can limit the storage rod 42 for contraction adjustment is installed on the outside of the sliding sleeve 41. The distance sleeve 43 is abutted against the sliding sleeve 41 for limiting the position by a tightening handwheel connected to its external thread, and a transmission gear 44 fixedly connected to one end of the sliding sleeve 41 can be meshed and adapted with the sliding gear sleeve column 6 for transmission.

[0051] The bridge and culvert height limit reminder device utilizes that when the height limit roller 3 is lifted by an overheight vehicle, a storage rod 42 hingedly installed on one side thereof flips over and retracts into a sliding sleeve 41, thereby realizing a flipping action of the limit adjustment rod 4, so that the movable and flipped limit adjustment rod 4 is meshed and adapted with the sliding gear sleeve column 6 for transmission, thereby realizing the limit movement of the sliding gear sleeve column 6, driving the light indicator rod 5 to flip over for interception, and the fixed distance sleeve 43 can regulate the telescopic length of the storage rod 42 and the sliding sleeve 41, thereby realizing the height limit adjustment of the height limit roller 3.

[0053] The bridge and culvert height limit reminder device utilizes the light indicator rods 5 arranged in a staggered symmetrical structure, so that when the sliding gear sleeve column 6 is affected by an over-height vehicle, it drives the light indicator rods 5 installed on both sides to realize positive and negative rotation, so that the light indicator rod 5 on the side of the front of the vehicle is limited to turn down to provide a conspicuous interception for the driver, and the light indicator rod 5 on the side of the rear of the vehicle is limited to turn up to remind the rear vehicle to keep a safe distance, so as to facilitate the backing operation of the over-height vehicle.

[0054] Working principle: When the vehicle is traveling at a low speed along the guide channel frame 1 for super-height detection, if the vehicle is lower than the height of the height-limiting roller 3, the device will not intercept. If the vehicle exceeds the height of the height-limiting roller 3, the height-limiting roller 3 will be lifted by the super-height vehicle body and move upward along the track of the height-limiting guide frame 2;

[0055] At this time, the upward-moving height-limiting roller 3 drives the externally hinged position-limiting adjusting rod 4 to shrink and flip, and the flipped position-limiting adjusting rod 4 is meshed and transmitted with the sliding gear sleeve column 6 under the action of the transmission gear 44, and the downward-moving sliding gear sleeve column 6 drives the gear sleeve 61 fixedly connected on one side to mesh and transmit with the passive gear 51 fixedly connected to the outside of the light indicator rod 5, thereby realizing the interception and flipping function of the light indicator rod 5;

[0056] The light indicator bar 5 on one side of the front of the vehicle is limited to turn down to intercept the driver, and the light indicator bar 5 on one side of the rear of the vehicle is limited to turn up to remind the rear vehicles to keep the distance.
