Description

Technical Field

[0001] The utility model relates to the field of measuring instruments, in particular to a rapid measuring instrument for the compaction degree of a water-stable base layer. Background Art

[0002] The compaction of the road base is the key to ensure the performance of the road surface and is also an important indicator of the quality of road construction. At present, the construction party mainly uses the sand filling method to detect the compaction. The sand filling method requires digging a pit on the roadbed to the bottom of the rolling layer, weighing the mass of the excavated sample, measuring the moisture content and volume of the sample, calculating the wet density, and converting the calculated wet density to the dry density. Finally, the actual compaction of the roadbed and road filling material is calculated. At present, when using the sand filling method to detect the compaction, a cylindrical hole is manually dug on the water-stable base with a hammer, screwdriver, flat shovel and other tools, and the compaction of the soil sample taken out of the hole is measured. This sampling method is not only time-consuming and labor-intensive, but also difficult to operate, and is prone to irregular sampling holes, poor sampling effects, and inaccurate test data, so it needs to be improved.

The rapid tester for the compaction degree of water-stable base drives the screw to rotate through the rotation of the first motor, so that the connecting plate moves up and down, thereby moving the sampling tube up and down, and drives the connecting rod to rotate through the rotation of the second motor, so that the sampling tube connected to the connecting rod rotates, and drives the blade set on the sampling tube to complete the sampling of the water-stable base, making the sampling of the water-stable base more convenient, and avoiding the problem of irregular sampling holes that are easy to appear during manual operation.

[0004] In the existing technology, when sampling for soil compaction measurement, since most soil samples are accompanied by sand and gravel particles, the soil sample is easily fixed inside the sampling tube after being extracted by the sampling tube, which makes it difficult to extract the soil sample, and thus makes the compaction measurement difficult.

[0005] Therefore, it is necessary to provide a rapid measuring instrument for the compaction degree of water-stable base to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

The rapid measuring instrument for compaction degree of water-stable base comprises a support platform 1, a sampling box 2 is fixedly connected to the top of the support platform 1, a No. 1 cylinder 3 is fixedly installed on the top of the inner cavity of the sampling box 2, a sampling tube 4 is fixedly connected to the bottom of the No. 1 cylinder 3, a No. 2 cylinder 5 is fixedly installed on the top of the sampling box 2, a pushing block 6 is fixedly sleeved on the bottom of the No. 2 cylinder 5, a counterweight 7 is fixedly connected to the top of the support platform 1, a reduction motor 8 is fixedly installed on the bottom of the support platform 1, a rotating plate 9 is fixedly sleeved on the output end of the reduction motor 8, a measuring instrument body 10 is fixedly installed on the top of the rotating plate 9, a guide cover 11 is fixedly sleeved on the top of the measuring instrument body 10, a sliding ball 12 is movably sleeved on the bottom of the inner cavity of the sampling box 2, a control host 13 is fixedly installed on the side of the sampling box 2, a No. 3 cylinder 14 is fixedly installed on the bottom of the support platform 1, a non-slip seat 15 is fixedly connected to the bottom of the No. 3 cylinder 14, and a moving mechanism 16 is arranged at the bottom of the support platform 1.

[0026] The push block 6 is movably sleeved inside the sampling tube 4, and the push block 6 is adapted to the sampling tube 4; by setting the push block 6, when soil sampling is being carried out, the No. 1 cylinder 3 is started, so that the No. 1 cylinder 3 can drive the sampling tube 4 to enter the soil and extract the soil sample. When the soil sample enters the sampling tube 4, the sampling tube 4 is lifted and the No. 2 cylinder 5 is started, so that the No. 2 cylinder 5 can drive the push block 6 to squeeze the soil sample inside the sampling tube 4, so that the soil sample can be discharged into the sampling box 2, thereby achieving the soil sample extraction and discharge effect, thereby avoiding the problem of clogging the sampling tube 4 when the soil sample is relatively solid and difficult to discharge, thereby bringing convenience to the extraction of soil samples.

[0027] The material of the counterweight block 7 is carbon steel, and the number of the counterweight blocks 7 is four; by setting the counterweight block 7, when soil sampling is being carried out, the counterweight block 7 can squeeze the support platform 1, thereby greatly increasing the weight of the support platform 1, thereby avoiding the problem that the sampling tube 4 squeezes the ground when taking soil samples, causing the support platform 1 to shake, thereby improving the stability of the support platform 1 when soil samples are taken.

[0028] The rotating plate 9 is movably sleeved inside the sampling box 2, and the rotating plate 9 and the sampling tube 4 are perpendicular to each other; by setting the rotating plate 9, when it is necessary to carry out soil sample discharge measurement, the reduction motor 8 is started, so that the reduction motor 8 can drive the rotating plate 9 to rotate, and at this time the rotating plate 9 can drive the guide cover 11 to move to the sampling tube 4 to the bottom of the guide cover 11 through the measuring instrument body 10, so that the soil sample can be discharged into the guide cover 11, thereby achieving the effect of collecting the soil sample.

[0029] There are several sliding balls 12, which are evenly distributed under the rotating plate 9. By setting the sliding balls 12, when soil samples need to be collected, the sliding balls 12 can support the rotating rotating plate 9, thereby avoiding the problem of friction between the rotating plate 9 and the bottom of the inner cavity of the sampling box 2 when rotating, thereby improving the stability of the rotating plate 9 when rotating, that is, improving the stability of the guide cover 11 when moving.

[0030] The measuring instrument body 10 is located directly below the guide cover 11, and the input end of the measuring instrument body 10 is signal-connected to the output end of the control host 13; by setting the measuring instrument body 10, when soil sample measurement is required, the measuring instrument body 10 and the control host 13 are started, so that the measuring instrument body 10 can measure the soil sample inside the guide cover 11, and then the measurement result is quickly displayed through the control host 13, thereby improving the convenience of soil sample measurement.

[0031] There are two No. 3 cylinders 14, and the two No. 3 cylinders 14 are symmetrically distributed with the sampling box 2 as the symmetry axis; by setting the No. 3 cylinder 14, when soil sampling is required, the No. 3 cylinder 14 is started, so that the bottom of the No. 3 cylinder 14 is tightly pressed against the ground, thereby achieving the fixing effect of the support platform 1, thereby avoiding the problem of shaking of the support platform 1 when soil sampling is taken, thereby improving the stability of the measuring instrument body 10 during soil sample measurement.

[0032] The anti-slip seat 15 and the No. 3 cylinder 14 are perpendicular to each other, and there are two anti-slip seats 15; by setting the anti-slip seat 15, when the position of the support platform 1 is fixed, the anti-slip seat 15 can greatly increase the contact area between the bottom of the No. 3 cylinder 14 and the ground, that is, increase the friction between the bottom of the No. 3 cylinder 14 and the ground, thereby improving the stability of the support platform 1 when it is fixed.

[0033] The moving mechanism 16 includes a support column 161, which is fixedly connected to the bottom of the support platform 1, and a sliding wheel 162 is installed at the bottom of the support column 161; by setting the moving mechanism 16, when it is necessary to take soil samples at different positions, the support platform 1 is pushed, so that the sliding wheel 162 can drive the support platform 1 to move horizontally through the support column 161, that is, drive the sampling box 2 to move horizontally, thereby bringing convenience to the taking of soil samples in different areas.

[0034] The working principle of the water-stable base compaction rapid measuring instrument provided by the utility model is as follows:

[0035] The first step: first, when taking soil samples, start the No. 1 cylinder 3, so that the No. 1 cylinder 3 can drive the sampling tube 4 into the soil and extract the soil sample. When the soil sample enters the sampling tube 4, lift the sampling tube 4 and start the No. 2 cylinder 5, so that the No. 2 cylinder 5 can drive the pushing block 6 to squeeze the soil sample inside the sampling tube 4, so that the soil sample can be discharged into the sampling box 2, thereby achieving the soil sample extraction and discharge effect, thereby avoiding the problem of clogging the sampling tube 4 when the soil sample is relatively solid and difficult to discharge, thereby bringing convenience to the extraction of soil samples. When extracting soil samples, the counterweight block 7 can squeeze the support platform 1, thereby greatly increasing the weight of the support platform 1, so that the sampling tube 4 soil sample is avoided from squeezing the ground, causing the support platform 1 to shake, thereby improving the stability of the support platform 1 when soil samples are taken. When the sample is discharged and measured, the reduction motor 8 is started, so that the reduction motor 8 can drive the rotating plate 9 to rotate. At this time, the rotating plate 9 can drive the guide cover 11 to move to the sampling tube 4 to the bottom of the guide cover 11 through the measuring instrument body 10, so that the soil sample can be discharged into the inside of the guide cover 11, thereby achieving the effect of collecting the soil sample. When it is necessary to collect the soil sample, the sliding ball 12 can support the rotating rotating plate 9, thereby avoiding the problem of friction between the rotating plate 9 and the bottom of the inner cavity of the sampling box 2 when rotating, thereby improving the stability of the rotating plate 9 when rotating, that is, improving the stability of the guide cover 11 when moving. When it is necessary to measure the soil sample, the measuring instrument body 10 and the control host 13 are started, so that the measuring instrument body 10 can measure the soil sample inside the guide cover 11, and then the measurement result is quickly displayed through the control host 13, thereby improving the convenience of soil sample measurement;

[0036] Step 2: When it is necessary to take soil samples, start the No. 3 cylinder 14 so that the bottom of the No. 3 cylinder 14 can be tightly pressed against the ground, thereby achieving the fixing effect of the support platform 1, thereby avoiding the problem of shaking of the support platform 1 when taking soil samples, thereby improving the stability of the measuring instrument body 10 during soil sample measurement. When the position of the support platform 1 is fixed, the anti-slip seat 15 can greatly increase the contact area between the bottom of the No. 3 cylinder 14 and the ground, that is, increase the friction between the bottom of the No. 3 cylinder 14 and the ground, thereby improving the stability of the support platform 1 when it is fixed. When it is necessary to take soil samples at different positions, push the support platform 1, so that the sliding wheel 162 can drive the support platform 1 to move horizontally through the support column 161, that is, drive the sampling box 2 to move horizontally, thereby bringing convenience to the taking of soil samples in different areas.

[0037] Compared with the related art, the water-stable base compaction rapid determination instrument provided by the utility model has the following beneficial effects:

[0038] By setting the pushing block 6, when soil sampling is being carried out, the No. 1 cylinder 3 is started, so that the No. 1 cylinder 3 can drive the sampling tube 4 to enter the soil and extract the soil sample. When the soil sample enters the sampling tube 4, the sampling tube 4 is lifted and the No. 2 cylinder 5 is started, so that the No. 2 cylinder 5 can drive the pushing block 6 to squeeze the soil sample inside the sampling tube 4, so that the soil sample can be discharged into the sampling box 2, thereby achieving the soil sample extraction and discharge effect, thereby avoiding the problem of the soil sample being blocked in the sampling tube 4 when it is relatively solid and difficult to discharge, thereby bringing convenience to the extraction of soil samples.
