Description

Technical Field

[0001] The utility model relates to the technical field of road measurement, in particular to a length measuring device for road maintenance. Background Art

[0002] Road maintenance refers to the maintenance, repair, and management of roads and their ancillary facilities that have been completed, accepted, and put into use, in order to ensure that the roads are in good technical condition and safe and unobstructed. Road maintenance includes roadbed maintenance, pavement maintenance, bridge and culvert maintenance, etc. When a road surface is used for too long, it is inevitable that potholes or cracks will appear. When repairing road damage, it is first necessary to accurately measure the length of the damaged part of the road surface in order to formulate a repair plan. The commonly used measurement method is to use a tape measure or folding ruler for measurement. Since damaged roads will have potholes or bumps, when the measuring ruler passes through the raised position of the road surface, the measuring ruler will be lifted by the road surface, resulting in inaccurate measurement results. The commonly used solution is to bypass the raised position of the road surface and measure closer data near the raised position. However, accurate measurement data cannot be obtained. In view of this, we propose a length measuring device for road maintenance. Utility Model Content

[0003] The purpose of the utility model is to provide a length measuring device for road maintenance, so as to solve the problem in the background art that the existing measuring ruler is difficult to accurately measure the length of the road surface at the raised position of the road surface.

[0004] To achieve the above-mentioned purpose, the present invention provides a length measuring device for road maintenance, comprising a No. 1 ruler plate, a No. 2 ruler plate being provided on one side of the No. 1 ruler plate, a connecting assembly being provided between the No. 1 ruler plate and the No. 2 ruler plate, the connecting assembly comprising two No. 3 ruler plates, one end of the two No. 3 ruler plates being slidably provided inside the No. 1 ruler plate and the No. 2 ruler plate, two No. 4 ruler plates being provided between the two No. 3 ruler plates, one end of the two No. 4 ruler plates being respectively fitted with one end of the two No. 3 ruler plates, a distance adjustment assembly being provided in the middle of the two No. 4 ruler plates, and a lifting assembly being provided between the No. 3 ruler plate and the No. 4 ruler plate.

[0005] The distance adjustment component is used to adjust the length between the two No. 4 ruler plates to ensure that the two No. 4 ruler plates can cover the top of the raised position on the ground, and the lifting component is used to control the lifting of the two No. 4 ruler plates.

[0006] As a further improvement of the present technical solution, the distance adjustment assembly includes a connecting block, and the ends of the two No. 4 ruler plates that are close to each other are slidably arranged inside the connecting block, and the connecting block is used to connect the two No. 4 ruler plates.

[0007] As a further improvement of the present technical solution, a tooth block is provided on the side where the two No. 4 ruler plates are close to each other, and the two tooth blocks are slidably arranged inside the connecting block. A stop block is fixed between the No. 4 ruler plate and the tooth block to prevent the tooth block from sliding out of the connecting block.

[0008] As a further improvement of the present technical solution, a gear is provided between the two tooth blocks, the gear is rotatably provided inside the connecting block, the gear is meshed and connected with the two tooth blocks, a knob is fixedly provided on the upper side of the gear, and one end of the knob is rotatably provided on the upper side of the connecting block.

[0009] The knob is used to drive the gear to rotate. When the gear rotates, it drives the two gear blocks to slide. When the two gear blocks slide, they push the two No. 4 scale plates away from each other or pull the two No. 4 scale plates toward each other. While the two gear blocks drive the two No. 4 scale plates to move, the two No. 4 scale plates drive the two No. 3 scale plates to slide.

[0010] As a further improvement of the present technical solution, the lifting assembly includes two telescopic rods, which are symmetrically fixed between the third scale board and the fourth scale board, and the telescopic rods are arranged on the lower side of one end of the fourth scale board.

[0011] As a further improvement of the present technical solution, a tension spring is provided between the two telescopic rods, and the tension spring is fixedly provided between the third scale plate and the fourth scale plate. A pad for supporting the fourth scale plate is fixedly provided symmetrically on the left and right sides of one end of the third scale plate close to the fourth scale plate.

[0012] The two telescopic rods are used to connect the third and fourth ruler boards. When the third ruler board moves downward, the two telescopic rods gradually extend with the movement of the third ruler board and control the direction of movement of the third ruler board. When the third ruler board is in contact with the ground, the tension spring pulls the fourth ruler board downward until it is in contact with the highest point of the protrusion on the ground. The two pads are used to limit the fourth ruler board and control the fourth ruler board to move downward. When it moves downward, it can only move to the same level as the third ruler board. When the fourth ruler board moves to the same level as the third ruler board, it contacts the two telescopic rods and cannot move downward any further.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this road maintenance length measuring device, the user first turns the knob to drive the two No. 4 rulers to move away from each other, so that the distance between the two No. 4 rulers is the same as the length of the raised section on the ground. The user then places the distance adjustment component on the raised position of the road surface, and then presses the No. 1 ruler and the No. 2 ruler downward until they are in contact with the ground. During the pressing process, the two No. 3 rulers move downward along with the No. 1 ruler and the No. 2 ruler, and the telescopic rod gradually extends along with the movement of the No. 3 ruler. At the same time, the tension spring pulls the No. 4 ruler to fit the highest point of the raised part of the ground, ensuring that the device can normally measure the length at the raised position on the ground, thereby improving the measurement accuracy of the device.
