Description

Technical Field

[0001] The utility model relates to the technical field of road thickness measurement, in particular to a road thickness laser measuring instrument. Background Art

[0002] Highway thickness measurement is crucial for ensuring pavement strength and stability. The thickness of each pavement layer is closely related to the overall strength of the road. Only by ensuring this thickness can the strength of each layer and the overall structure of the road be guaranteed. Furthermore, strict control of the thickness of each structural layer can also play a role in controlling the elevation of the road surface.

[0003] After searching, it was found that the publication number CN221037198U discloses a road thickness detection device, which includes a coring machine. When the above device is in use, although the reading accuracy of the measuring ruler is guaranteed, the equipment will be cooled by flushing water when rotating the hole to take samples, and the cooling water will enter the hole. When filling the hole, the staff needs to pump out the water, which is quite laborious. For this reason, a road thickness laser measuring instrument is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that when the equipment is rotating the hole to take samples, it will cool down by flushing water, and the cooling water will enter the hole. When filling the hole, the staff needs to pump out the water, which is relatively laborious. A highway thickness laser measuring instrument is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A highway thickness laser measuring instrument comprises a base plate, one side of which is slidably connected to two sliding frames, a guide rod being fixedly connected between the top inner wall and the bottom inner wall of the sliding frame, a slider being slidably connected to the circumference of the guide rod, a threaded rod being rotatably connected between the top inner wall and the bottom inner wall of the sliding frame, the threaded rods respectively threadedly passing through the sliders, one side of one of the sliders being fixedly connected to a motor, one end of the motor output shaft being fixedly connected to a drill bit for sampling, and one side of the other slider being fixedly connected to a penetrating water pumping pipe, the bottom of which being fixedly connected to a filter cartridge for filtering particulate matter;

[0007] The two sliding frames are fixedly connected, the surface of the bottom plate is fixedly connected with a fixing frame, and the top of the fixing frame is fixedly connected with three laser distance measuring sensors for distance measurement.

[0008] As a further solution of the present invention, two limiting blocks are fixedly connected to the surface of the bottom plate for limiting the sample.

[0009] As a further solution of the present invention, the surface of the base plate is fixedly connected to a vertical plate, a penetrating rod is inserted into one side of the vertical plate, and a through hole is opened on one side of the sliding frame. The rod is inserted into one of the through holes, and a spring is fixedly connected between the rod and the vertical plate.

[0010] As a further solution of the present invention, the surface of the base plate is fixedly connected to a water storage tank, the surface of the base plate is fixedly connected to a water pump, the water pumping end of the water pump is fixedly connected to the water storage tank, the water outlet end of the water pump is fixedly connected to a water outlet pipe, and the end of the water outlet pipe away from the water pump is located on one side of the drill bit.

[0011] As a further solution of the present invention, the surface of the base plate is fixedly connected to a water collecting box, the top of the water collecting box is fixedly connected to a fan, the exhaust end of the fan is fixedly connected to the water collecting box, a filter is fixedly connected between the inner walls on both sides of the water collecting box, and one end of the suction pipe is fixedly connected to the water collecting box and is located below the filter.

[0012] As a further solution of the present invention, a plurality of penetrating adjustment rods are threadedly connected to the surface of the base plate.

[0013] In this application, when in use, the device is moved to the position to be measured, and then the adjustment rod is rotated to adjust the level of the base plate to prevent the device from moving during use and improve stability during use. Then the staff stands on the surface of the base plate to increase the stability of the equipment. When sampling, the water pump and motor are started. The motor drives the drill bit to rotate, and at the same time the water pump injects water into one side of the drill bit. Then the threaded rod that controls the movement of the motor is rotated. The threaded rod drives the slider downward, and then the road is drilled through the drill bit. After the drilling is completed, the drill bit is reset, and then the drilled sample is taken out and placed between two limit blocks. When placing, keep the flat side of the sample facing down, and then use the laser ranging sensor to measure the height of the sample. After sampling is completed, pull the insertion rod, then move the sliding frame, and then insert the insertion rod into the through-hole on the other sliding frame. Similarly, by rotating the threaded rod, the filter box is controlled to move downward so that the filter box enters the hole after sampling. Then the fan is started and the water in the hole is pumped out by the negative pressure principle to facilitate subsequent filling of the hole.

[0014] Beneficial effects:

[0015] In the utility model, the highway thickness laser measuring instrument cooperates with the drill bit and the water extraction pipe, so that after the drill bit rotates the hole to take a sample, the filter box can be moved downward, and then the fan can be started to extract the water in the hole, so as to facilitate the subsequent filling of the hole.

[0016] In the utility model, the highway thickness laser measuring instrument is used in conjunction with a water pump and a water outlet pipe, so that when drilling, the water pump can be started to spray water toward the drill hole, thereby reducing the temperature of the drill bit and avoiding the problem of dust.

[0017] In the utility model, after the drill bit rotates the hole to take a sample, the filter box can be moved downward, and then the fan can be started to extract the water in the hole, which is convenient for subsequent filling of the hole. At the same time, the water pump can be started to spray water toward the drill hole to reduce the temperature of the drill bit and avoid the problem of dust. BRIEF DESCRIPTION OF THE DRAWINGS
