Description

Technical Field

[0001] The utility model relates to the field of crack monitoring equipment, in particular to a road surface crack monitoring device. Background Art

[0002] After an earthquake, cracks are common on cement pavements. For safety reasons, the cracks need to be monitored and their development needs to be known in real time. Currently, cracks are measured manually with a tape measure, and the measured data is recorded in a notebook to understand the development of the cracks. The data recorded in the notebook is used to compare the speed of pavement cracking. However, it is impossible to always understand the measured data by just measuring with a tape measure.

[0003] According to the patent document with the existing publication number CN108824148B, a post-earthquake cement pavement crack monitoring device is disclosed, which includes a shell, a first connecting plate, a slide rail, a slider, a mounting plate, a handle, a pull rope, a hanging ring, a hook, a motor, a drill bit, a handle, a block, a movable plate, a second connecting plate, a cross plate, a tape measure body and a tape measure strip. The front side and the rear side of the shell are both open-type settings, and the lower part of the left side of the shell is connected to the first connecting plate, and the first connecting plate is provided with a first threaded hole. When this technical solution is in use, the length of the tape measure strip pulled out and the distance the shell moves to the left can intuitively monitor the cracks and can more accurately display the cracking conditions of the cracks. The roller brush can clean the tape measure strip and brush off the dust on the tape measure strip, so that the tape measure strip can be kept clean. Regarding the above technical solution, although this solution realizes the cleaning of the tape measure strip, the shell cannot be tilted and moved for measurement during use, which is inconvenient during use.

The utility model has a novel structure. When in use, the support rod is installed on the sliding block through the fixed column to achieve connection with the fixed rod. Later, the support rod and the fixed rod are installed at an angle according to the shape of the crack, and the fixed column rotates inside the opening to meet the crack measurement at different angles.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a pavement crack monitoring device, including a monitoring device body, the monitoring device body including a fixed seat, a fixing rod is fixed on one side of the fixing seat, a support rod is movably installed on the bottom of the fixing rod, a support seat is fixed on one end of the support rod, sleeves are welded on the support seat and the fixing seat, a movable column is movably installed inside the sleeve, a cavity is opened inside the fixing seat, and a tape measure is fixedly installed inside the cavity.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figure 1 and Figure 2 The utility model provides a technical solution: a pavement crack monitoring device, including a monitoring device body, the monitoring device body including a fixed seat 1, a fixed rod 2 is fixed on one side of the fixed seat 1, a support rod 3 is movably installed at the bottom of the fixed rod 2, a support seat 4 is fixed at one end of the support rod 3, a sleeve 5 is welded on the support seat 4 and the fixed seat 1, a movable column 6 is movably installed inside the sleeve 5, a cavity 13 is opened inside the fixed seat 1, a tape measure 14 is fixedly installed inside the cavity 13, a slide groove 9 is opened on the support rod 3, a slider 10 is movably installed inside the slide groove 9, a measuring plate 15 is fixedly installed on the slider 10, and the measuring plate 15 is a tape measure plate, which is later retracted to the inside of the tape measure 14 under the drive of the tape measure 14.

[0022] In this embodiment, one end of the measuring plate 15 is fixedly installed inside the tape measure 14, the slider 10 is provided with an opening 16, a fixed column 11 is movably installed inside the opening 16, a scale line 12 is provided on the fixed column 11, one end of the fixed column 11 is fixed to the support rod 3, a limiting groove 17 is provided on the inner wall of the slide 9, a limiting block 18 is movably installed inside the limiting groove 17, and the limiting block 18 is fixed to the side of the slider 10, one end of the movable column 6 is fixed with a cutting 8, one end of the sleeve 5 is welded with a limiting disk 7, the movable column 6 is installed on the ground through the cutting 8 when knocked, the sleeve 5 moves downward with the limiting disk 7, and the limiting disk 7 provides limiting support for the sleeve 5 after contacting the ground, and the limiting disk 7 provides limiting support force for the fixed seat 1 and the support seat 4 through the sleeve 5.

[0023] When the device is in use, the cutting 8 drives the movable column 6 to be installed on both sides of the crack respectively, and the top of the movable column 6 is knocked with an external tool. The movable column 6 enters the bottom of the ground through the cutting 8. When the cutting 8 and the movable column 6 move downward, the limit plate 7 contacts the ground, and the limit plate 7 supports and limits the fixed seat 1 and the support seat 4 through the sleeve 5. When the movable column 6 is fixed, the fixed seat 1 is moved upward on the movable column 6 through the sleeve 5, and the fixed rod 2 is moved to the top of the support rod 3, and then the fixed seat 1 and the fixed rod 2 are lowered. When the fixed rod 2 is lowered, the measuring plate 15 is pulled out from the inside of the tape measure 14 through the slider 10, and the opening 16 on the slider 10 is aligned with one side of the fixed column 11. The ends are aligned, and after alignment, the slider 10 is installed on the fixed column 11 through the opening 16. The fixed column 11 cooperates with the opening 16 to realize the rapid adjustment of the fixed rod 2 and the support rod 3. After the slider 10 and the fixed column 11 are connected, the values ​​exposed on the measuring plate 15 are observed and recorded. In addition, the position of the scale line 12 on the fixed column 11 on the slider 10 is recorded, and the record is used to complete the monitoring of the later ground settlement. When in use, when the cracks between the movable columns 6 increase, the fixed column 11 drives the slider 10 to move inside the slide groove 9, and the movement causes the measuring plate 15 to be pulled out or contracted for a distance. The monitoring personnel need to regularly watch the values ​​on the measuring plate 15 to complete the monitoring of the crack size.
