Description

Technical Field

[0001] The invention relates to a foundation detection device for highway construction, in particular to a foundation detection device for highway construction, and belongs to the technical field of foundation detection devices. Background Art

[0002] Highways refer to public roads between cities, between urban and rural areas, and between villages that can be used for driving cars and have been approved by the transportation authorities. After the construction of a highway is completed, it is necessary to conduct foundation testing to ensure the bearing effect of the foundation. In the foundation bearing capacity test, hydraulic equipment is usually used to push the test head to perform a pressure test on the foundation, and the test head is reciprocated by a reciprocating device to perform a foundation bearing capacity test. The hydraulic equipment can accurately control the pressure applied to the test head to ensure that the pressure during the test is stable and repeatable, thereby improving the accuracy of the test. By reciprocating the test head with a reciprocating device, a comprehensive test of different depths and areas of the foundation can be achieved. This dynamic testing method helps to discover potential weaknesses and unevenness in the foundation.

It includes a mobile frame, the upper ball of the mobile frame is connected to a rotating shaft, the rotating shaft is provided with a bogie, and the bogie is fixedly connected to a connecting frame. The invention drives the bogie to swing under the action of gravity through the rotating shaft, so that the bogie drives the steel drill to rotate through the lifting frame, and finally makes the steel drill vertically downward, so as to avoid the steel drill from tilting to one side when measuring the bearing capacity of the foundation, resulting in deviations in the collected data, affecting the staff's analysis of the actual situation of the foundation."

[0004] The above patent has the following disadvantages: the above equipment cannot simulate the test of roadbed bearing capacity under specific humidity conditions during foundation testing, and may not be able to effectively control the humidity and temperature of the test area during testing, which may affect the physical and mechanical properties of the soil, such as internal friction angle, cohesion, etc., thereby indirectly affecting the test results of the bearing capacity, and dust may be raised during the bearing capacity test, which in turn causes the testing environment to deteriorate, and cannot reduce the impact on the environment and testers.

[0040] Specifically, a tube body 7 with a circular exterior and a hollow interior is welded to the lower surface of the mounting sleeve 4, an adjusting ring 8 is slidably sleeved on the outside of the tube body 7, and a connecting arm 9 is hingedly installed between the adjusting ring 8 and the telescopic supporting leg 5, and positioning bolts are installed inside the mounting sleeve 4 and the adjusting ring 8.

A handle is welded on the back of the sleeve 1.

[0042] In order to ensure that the detection probe 3 can perform foundation detection and improve construction efficiency, in this embodiment, Figure 3-Figure 9As shown, a driving mechanism for driving the detection probe 3 is provided on the sleeve 1, and a watering mechanism extending to the outside of the sleeve 1 for cooperating with the detection probe 3 for detection is provided on the shell 2, and a synchronization structure is provided between the driving mechanism and the watering mechanism; the driving mechanism includes a rotating shaft 10 rotatably arranged in the sleeve 1, a crank 11 fixedly installed at one end of the rotating shaft 10, a connecting rod 12 welded to the outside of the crank 11, a connecting piece arranged inside the sleeve 1 and rotatably connected to the detection probe 3, and a driving structure arranged outside the sleeve 1 and connected to the rotating shaft 10 for driving; the connecting piece includes a fixedly connected connecting rocker arm 13 and a connecting shaft 14 and a sliding connecting rod 12. A screw 15 is inside the connecting shaft 14 and a circular disk 16 is arranged at the bottom end of the screw 15. A rotating ball head 151 rotatably connected to the circular disk 16 is installed at the bottom end of the screw 15. The detection probe 3 is fixedly installed on the lower surface of the circular disk 16 and extends to the outside of the sleeve 1. The sprinkler mechanism includes a gear pump housing 24 and a water tank 25 fixedly installed on the inner bottom wall of the shell 2, a gear set 35 arranged inside the gear pump housing 24, a water spray pipe 28 rotatably installed on the outer surface of the sleeve 1, and a plurality of equidistantly arranged nozzles 29 fixedly connected to the outside of the water spray pipe 28. The upper surface of the water spray pipe 28 is fixedly connected with a connecting pipe 27, and the connecting pipe 27 is a hose. A connecting pipe 26 is installed on the opposite side of the gear pump housing 24, and the two connecting pipes 26 are fixedly connected to the connecting pipe 27 and the water tank 25 at the ends away from each other; the synchronous structure includes two synchronous wheels 30 and a synchronous belt 31 connected between the two synchronous wheels 30, and a synchronous shaft 32 is fixedly connected inside one of the synchronous wheels 30, and the other end of the synchronous shaft 32 is connected to the gear set 35. The driving structure includes a first driving motor 17 installed on the outer surface of the sleeve 1 by bolts, a driven gear 19 fixedly installed on the end of the rotating shaft 10 away from the sleeve 1, and a transmission gear 18 fixedly installed on the output shaft of the first driving motor 17 and meshing with the driven gear 19. Through the installation of the synchronous structure, when the detection probe 3 moves single or reciprocatingly, the gear set 35 can be synchronized, so as to spray water according to demand. The synchronous structure can ensure accurate synchronous movement between the watering structure and the roadbed stamping equipment, which means that the watering operation can be closely coordinated with the stamping operation without additional adjustment or waiting time, thereby improving the overall construction efficiency.

[0043] Specifically, there are two rotating shafts 10 and two cranks 11 , and the two rotating shafts 10 and the two cranks 11 are symmetrically arranged. The connecting rod 12 penetrates the rocker arm 13 and is installed between the two cranks 11 .

[0044] In this embodiment, if Fig. 9As shown, a pump chamber 34 is provided inside the gear pump housing 24, and a gear set 35 includes two meshing gears, and the two gears are rotatably arranged in the pump chamber 34. The synchronous shaft 32 extends into the pump chamber 34 and is connected and fixed to the top gear. The transmission cooperation between the synchronous wheel 30 and the synchronous belt 31 enables the detection probe 3 to spray water on the foundation when detecting the bearing capacity of the foundation. When the detection probe 3 moves single or reciprocatingly, the gear set 35 can be synchronized to spray water according to demand. The synchronous structure can ensure accurate synchronous movement between the watering structure and the roadbed stamping equipment, which means that the watering operation can be closely coordinated with the stamping operation without additional adjustment or waiting time, thereby improving the overall construction efficiency. At the same time, the watering amount can be accurately controlled according to the actual needs of the roadbed and the stamping progress, which helps to maintain a suitable moisture content on the roadbed surface, improve the compaction effect, and avoid waste and potential problems caused by excessive watering.

[0045] In this embodiment, if Fig.10 As shown, the outside of the sleeve 1 is provided with a reciprocating structure that is synchronized with the rotating shaft 10 and reciprocates the water spray pipe 28. The reciprocating structure includes a rotating seat 37 fixedly mounted on the outer wall of the sleeve 1 and rotatably connected to the two ends of the water spray pipe 28, a rotating disk 38 rotatably mounted on the outer wall of the sleeve 1, a special-shaped abutment plate 39 slidably mounted on the outside of the sleeve 1, and an abutment roller 40 fixedly mounted on the side of the water spray pipe 28 close to the sleeve 1 and rollingly connected to the special-shaped abutment plate 39. The back of the rotating disk 38 and the rotating shaft 10 are both equipped with a transmission wheel 41, and a transmission belt 42 is connected between the two transmission wheels 41. The rotating disk 38 is equipped with an annular sliding sleeve 3801 fixed to the top of the special-shaped abutment plate 39. A torsion spring is installed at the connection between the water spray pipe 28 and the rotating seat 37 to facilitate resetting.

[0046] An annular sliding groove is provided in the annular sliding sleeve 3801, and a sliding shaft that slides with the annular sliding groove is installed on the outside of the rotating disk 38. The rotating disk 38 rotates, and the sliding shaft and the annular sliding groove slide together to drive the special-shaped abutment plate 39 to reciprocate up and down, thereby cooperating with the abutment roller 40 to adjust the angle of the water spray pipe 28, thereby increasing the spraying range, improving the dust reduction effect, and increasing the test range. The special-shaped abutment plate 39 and the abutment roller 40 are located in the middle of the water spray pipe 28.

[0047] like Figure 8As shown, the connecting shaft 14 is provided with an adjusting device for telescopically adjusting the screw 15; the adjusting device includes a screw sleeve 20 rotatably mounted on the outer surface of the bottom end of the connecting shaft 14 and threadedly connected to the screw 15, a second drive motor 21 fixedly mounted on the outer wall of the bottom end of the connecting shaft 14, a worm 22 fixedly mounted on the output shaft of the second drive motor 21, and a worm wheel 23 fixedly mounted on the outer surface of the screw sleeve 20 and meshing with the worm 22. The transmission cooperation of the second drive motor 21, the worm 22 and the worm wheel 23 is used to realize the telescopic adjustment of the detection probe 3, so that it can perform stamping detection of different depths of the foundation, and thus can adapt to foundations of different depths.

[0048] like Figure 7 and Figure 8 As shown, a shock absorbing structure 33 is arranged between the inside of the sleeve 1 and the circular disk 16. The shock absorbing structure 33 includes a guide rod and a spring fixedly installed inside the sleeve 1, and the guide rod passes through the inside of the circular disk 16. The top of the spring is fixed to the lower surface of the circular disk 16, and the spring surrounds the outside of the guide rod. A through hole 36 for the detection probe 3 is opened at the bottom of the sleeve 1, and the detection probe 3 extends to the outside of the sleeve 1 through the through hole 36, and the shock absorbing structure 33 is located above the through hole 36.

[0049] like Figure 1-Figure 9 As shown, the principle of the foundation detection device for highway construction provided by this embodiment is as follows: when in use, the detection probe 3 drives the connecting rocker arm 13 through the transmission cooperation of the first drive motor 17, the transmission gear 18 and the driven gear 19, and moves in a circle, so that the detection probe 3 moves single or reciprocatingly to achieve different testing functions of the foundation, and can perform accurate stamping tests on different soil layers, so as to more comprehensively understand the overall performance of the roadbed. At the same time, the transmission cooperation of the second drive motor 21, the worm 22 and the worm wheel 23 is used to realize the telescopic adjustment of the detection probe 3, so that it can perform stamping detection of different depths of the foundation, and then can adapt to foundations of different depths. When the detection probe 3 performs stamping detection, the transmission cooperation of the synchronous wheel 30 and the synchronous belt 31 is used to make the gear set 35 move synchronously, so as to extract the liquid in the water tank 25 and transport it to the water spray pipe 28, and use the nozzle 29 to spray, so as to keep the surface of the roadbed moist, so as to reduce dust and improve the stamping effect;

[0050] In addition, when the detection probe 3 moves single or reciprocatingly, the gear set 35 can be made to move synchronously, so as to spray water according to demand. The synchronous structure can ensure accurate synchronous movement between the watering structure and the roadbed stamping equipment, which means that the watering operation can be closely coordinated with the stamping operation without additional adjustment or waiting time, thereby improving the overall construction efficiency. At the same time, the watering amount can be accurately controlled according to the actual needs of the roadbed and the progress of the stamping, which helps to maintain a suitable moisture content on the roadbed surface, improve the compaction effect, and avoid waste and potential problems caused by excessive watering. When the rotating shaft 10 rotates, the transmission of the transmission wheel 41 and the transmission belt 42 is utilized to make the rotating disk 38 drive the special-shaped abutment plate 39 to reciprocate up and down, and through the rolling cooperation with the abutment roller 40, the angle of the water spray pipe 28 is adjusted, thereby expanding the water spray range;

[0051] It is worth noting that the following is a full description of the motion process of the drive mechanism, the sprinkler mechanism and the reciprocating structure of the present invention:

[0052] 1. A rotating ball head 151 is installed at the bottom end of the screw rod 15 in the driving mechanism. The rotating ball head 151 is the same as the ball head universal shaft in the prior art. It is realized by the cooperation of the spherical rod and the spherical groove. The spherical rod can rotate freely in the spherical groove. When the rotating shaft 10 drives the crank 11 to rotate, since the connecting rod 12 rotates with the connecting rocker arm 13, the crank 11 will drive the connecting shaft 14 to reciprocate up and down during the circular motion. The rotating ball head 151 rotates with the circular disk 16, thereby preventing the detection probe 3 from moving in a circle around the driven gear 19;

[0053] In addition, the connecting shaft 14 will tilt to a certain extent when it reciprocates up and down. By using the guide rod limit in the shock-absorbing structure 33, the circular disk 16 drives the detection probe 3 to reciprocate up and down to achieve detection.

[0054] In addition, the driving of the second drive motor 21, the worm 22 and the worm wheel 23 is carried out separately from the first drive motor 17, and the situation of the detection probe 3 in the sleeve 1 can be observed through the through hole 36 for adjustment. The second drive motor 21 will not be used at the same time as the first drive motor 17, and the adjustment of the second drive motor 21, the worm 22 and the worm wheel 23 is a small adjustment;

[0055] 2. The sprinkler mechanism is an existing publicly available gear pump. The working principle of the gear pump is based on the rotational motion of the gears. The liquid is transported through the volume change formed during the gear meshing process. The gear pump consists of a pair of meshing gears, a pump casing and a pump chamber to form one or more closed working volumes. When the gears rotate, the volume of the space on the side where the gears are disengaged increases, forming a vacuum, thereby sucking in the liquid; while the volume of the space on the side where the gears are meshing decreases, squeezing the liquid out and discharging it into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of the two gears. The discharge pressure of the gear pump depends entirely on the resistance at the pump outlet.

[0056] Specifically, the working process of the gear pump includes two main stages: oil suction and oil discharge:

[0057] ‌Oil suction process‌: When the driving gear in the gear set 35 rotates, the gear teeth gradually disengage to form an inter-tooth volume, which will gradually increase, thereby sucking in the liquid from the oil inlet. ‌Oil discharge process‌: As the driving gear rotates, the gear teeth mesh again, the inter-tooth volume gradually decreases, and the liquid is forced to be discharged from the oil outlet. The characteristics of gear pumps include simple and compact structure, small size, light weight, low price, strong self-priming force, insensitivity to oil contamination, easy maintenance, reliable operation, etc.; in addition, gear pumps also have the advantages of low noise, low pulsation, high pressure resistance and long life. Gear pumps are conventional equipment known to the public in the prior art, so the specific structural composition and working principle will not be described in detail in this article;

[0058] 3. The reciprocating structure utilizes the rotation of the rotating disk to drive the annular sliding sleeve that slides with it to drive the special-shaped abutment plate 39 to reciprocate up and down. First, the two ends of the water spray pipe 28 are rotatably connected with the rotating seat 37, and the rotating seat 37 is installed with a torsion spring that matches the connection of the two ends of the water spray pipe 28. Through the installation of the torsion spring, the water spray pipe 28 can automatically restore when it rotates, that is, the side of the special-shaped abutment plate 39 close to the water spray pipe 28 is provided with an arc-shaped protrusion that is lower on the top and higher on the bottom. The abutment roller 40 is used to roll on the arc-shaped protrusion to realize the squeezing of the special-shaped abutment plate 39 on the water spray pipe 28. Since the two ends of the water spray pipe 28 can rotate, when the bottom side of the special-shaped abutment plate 39 is connected to the abutment roller 40, the water spray pipe 28 will be squeezed to cause it to flip to a certain extent. Then, in conjunction with the setting of the torsion spring, when the top side of the special-shaped abutment plate 39 is connected to the abutment roller 40, the water spray pipe 28 will return to its original state, thereby realizing the adjustment of the spraying range;

[0059] In addition, the water spray pipe 28 is a section of water pipe and does not surround the outer surface of the sleeve 1.
