Description

Technical Field

[0001] The utility model belongs to the technical field of geological detection, and in particular relates to a geological detection device for construction engineering. Background Art

[0002] A construction project refers to an engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. In the geological detection process, a soil sampling device is needed to sample the soil.

[0003] For example, the Chinese patent with the publication number CN217033100U discloses a soil sampling device for engineering geological detection, including a bracket, a driving mechanism and a drill mechanism, the driving mechanism includes a guide rod welded on both sides of the top of the bracket, a motor mounting plate slidably mounted on the guide rod, a motor fixed on the motor mounting plate by bolts, and a threaded rod is screwed to the support seat through a threaded channel; the drill mechanism includes a swivel seat and a drill body mounted on the inner wall of the swivel seat, a sampling tube is installed inside the drill body, and a drill bit is installed at the bottom of the drill body by bolts. The beneficial effect of the utility model is that the drill bit, the drill body and the sampling tube can be disassembled separately after sampling, which is convenient for replacing and cleaning the sampling tube and the drill bit. When the drill bit runs downward, the motor mounting plate moves downward along the threaded rod, and the motor moves with the motor mounting plate to ensure the stability of the motor during the operation of the device. The support seat is hinged with support inclined rods on the outer walls on both sides away from each other, which is convenient for sampling work under different surface environments.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: when the device is in use, the supporting diagonal rod is not fixed on the supporting seat, which makes it easy for the supporting diagonal rod to rotate on the supporting seat, so that the hollow drill bit is easy to deviate when moving downward. In addition, this device is not easy to store and needs to occupy a lot of space. In view of this, we propose a geological detection device for construction engineering. Utility Model Content

[0006] The purpose of the utility model is to provide a geological detection device for construction engineering to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a geological detection device for construction engineering, comprising:

[0008] A cylinder, a sliding groove is provided in the cylinder, a sliding block is slidably installed in the sliding groove, three support rods are rotatably installed on the peripheral side of the sliding block and located in the sliding groove, a moving groove is provided in the cylinder and located on one side of the three support rods, a gear is fixedly installed on one side of the support rod and located in the moving groove, and a plurality of gear blocks are fixedly installed on the inner wall of the moving groove and located below the gear;

[0009] A driving assembly, which is located in the cylinder and is used to drive the sliding block to move up and down;

[0010] A limiting groove, wherein the limiting groove is provided in the cylinder and is located below the sliding groove, a sliding plate is slidably installed in the limiting groove, a motor is fixedly installed on the top of the sliding plate and located in the limiting groove, the output end of the motor passes through the sliding plate and is fixedly installed with a second threaded rod, the bottom end of the second threaded rod passes through the bottom of the limiting groove and extends to the outside and is fixedly installed with a drill bit, a cavity is provided in the drill bit, through grooves are symmetrically provided on the peripheral side of the drill bit, and the two through grooves are both connected to the cavity, a circular ring is fixedly installed on the peripheral side of the cylinder and is located above a plurality of tooth blocks;

[0011] An adjustment component is located in the cavity and is used to adjust the two through-slot seals.

[0012] When the top of the three support rods is lower than the circular ring, the circular ring will release the limit of the three support rods, and the gear will contact with the tooth blocks in the moving groove. Under the action of meshing, the gear will roll on the tooth blocks, and the gear will drive the support rod to rotate outward until the sliding block moves to the bottom of the sliding groove, and the three support rods will be fully opened outward and supported on the ground, ensuring that the three support rods will not rotate when there is no external force to turn the handle, thereby ensuring that the drill bit will not deviate when working.

[0013] By setting up a motor, the motor is started, and the output shaft of the motor rotates to drive the threaded rod 2 to rotate in the limit groove. Under the action of the thread, the threaded rod 2 will rotate in the cylinder and move downward. The downward movement of the threaded rod 2 will drive the sliding plate and the motor to move downward. At the same time, the output shaft of the motor will rotate in the sliding plate. The rotation and downward movement of the threaded rod 2 will drive the drill bit to rotate and move downward. The drill bit rotates and moves downward and extends into the ground. When the drill bit extends to a suitable position, the adjustment component can be set to release the seal of the two through grooves. Then, under the action of the rotation of the drill bit, the soil will enter the cavity through the two through grooves. Then the personnel can move the cylinder upward, and the cylinder can drive the drill bit to be pulled out of the ground and the soil in the cavity can be inspected.

[0014] In the above technical solution, further, the driving component includes:

[0015] A threaded rod 1 is rotatably mounted in the sliding groove, the top of the threaded rod 1 passes through the sliding block and the top of the sliding groove and extends to the outside, and a handle is fixedly mounted at the top of the threaded rod 1 and located above the cylinder.

[0016] When the handle is turned, the rotation of the handle drives the threaded rod to rotate. Under the action of the thread, the rotation of the threaded rod drives the sliding block to move downward in the sliding groove. The sliding block moves downward and drives the three support rods to move downward. The support rod moves downward and drives the gear to move downward until the top ends of the three support rods are lower than the ring. At this time, the ring will release the limit on the three support rods. At this time, the gear will contact several tooth blocks in the moving groove. Under the action of meshing, the gear will roll on several tooth blocks. At this time, the gear will drive the support rod to rotate outward until the sliding block moves to the bottom of the sliding groove. At this time, the three support rods will be fully opened outward and supported on the ground, ensuring that the three support rods will not rotate without external force to turn the handle, thereby ensuring that the drill bit will not deviate when working.

[0017] In the above technical solution, further, the sliding block is threadedly connected to the threaded rod 1, and the threaded rod 1 is rotationally connected to the cylinder.

[0018] In this technical solution, it is ensured that the rotation of the threaded rod 1 can drive the sliding block to move, and it is ensured that the threaded rod 1 can rotate normally in the cylinder.

[0019] In the above technical solution, further, the adjustment component includes:

[0020] The electric push rod is fixedly installed on the top of the cavity, and a conical head is fixedly installed at the output end of the electric push rod and located in the cavity, and the circumference of the conical head is tightly attached to the inner wall of the cavity.

[0021] In the present technical solution, the motor is started, and the output shaft of the motor rotates to drive the threaded rod 2 to rotate in the limit groove. Under the action of the thread, the threaded rod 2 will rotate in the cylinder and move downward. The downward movement of the threaded rod 2 will drive the sliding plate and the motor to move downward. At the same time, the output shaft of the motor will rotate in the sliding plate. The rotation and downward movement of the threaded rod 2 will drive the drill bit to rotate and move downward. The drill bit rotates and moves downward and extends into the ground. When the drill bit extends to a suitable position, the electric push rod is started, and the output end of the electric push rod drives the conical head to move upward. The upward movement of the conical head can release the seal of the two through grooves. Then, under the action of the rotation of the drill bit, the soil will enter the cavity through the two through grooves. Then the personnel will pull the drill bit out of the ground and inspect the soil in the cavity.

[0022] In the above technical solution, further, the conical head is slidably connected to the cavity, and the top surface of the conical head is higher than the top of the through groove.

[0023] In this technical solution, it is ensured that the conical head can slide normally in the cavity and that the conical head can completely seal the through groove.

The sliding block moves downward and drives the three support rods to move downward. The support rods move downward and drive the gears to move downward until the top ends of the three support rods are lower than the circular ring. At this time, the circular ring will release the limit on the three support rods. At this time, the gear will contact with a number of tooth blocks in the moving groove. Under the action of meshing, the gear will roll on the number of tooth blocks. At this time, the gear will drive the support rods to rotate outward until the sliding block moves to the bottom of the sliding groove.

[0079] Working principle: when in use, first turn the handle 9, and the rotation of the handle 9 drives the threaded rod 8 to rotate. Under the action of the thread, the threaded rod 8 rotates and drives the sliding block 3 to move downward in the sliding groove 2. The sliding block 3 moves downward and drives the three support rods 5 to move downward.

At this time, the three support rods 5 will be fully opened outward and supported on the ground, ensuring that the three support rods 5 will not rotate when there is no external force to rotate the handle 9, ensuring that the drill bit 15 will not deviate during operation;

[0080] Then the motor 13 is started, and the output shaft of the motor 13 rotates to drive the threaded rod 2 14 to rotate in the limit groove 11. Under the action of the thread, the threaded rod 2 14 will rotate in the cylinder 1 and move downward. The downward movement of the threaded rod 2 14 will drive the sliding plate 12 and the motor 13 to move downward. At the same time, the output shaft of the motor 13 will rotate in the sliding plate 12. The rotation and downward movement of the threaded rod 2 14 will drive the drill bit 15 to rotate and move downward. The drill bit 15 rotates and moves downward and extends into the ground. When the drill bit 15 extends to a suitable position, the electric push rod 17 is started, and the output end of the electric push rod 17 drives the conical head 18 to move upward. The upward movement of the conical head 18 can release the seal of the two through grooves 19. Then, under the action of the rotation of the drill bit 15, the soil will enter the cavity 16 through the two through grooves 19. Then the personnel can move the cylinder 1 upward, and the cylinder 1 can drive the drill bit 15 to be extracted from the ground and the soil in the cavity 16 can be tested.

[0081] Afterwards, the personnel can turn the handle 9, and the rotation of the handle 9 drives the threaded rod 8 to rotate. Under the action of the thread, the threaded rod 8 rotates and drives the sliding block 3 to move upward in the sliding groove 2. The sliding block 3 moves upward and drives the three support rods 5 to move upward. The support rod 5 moves downward and drives the gear 6 to move upward. Under the action of meshing, the gear 6 will roll on several tooth blocks 7. At this time, the gear 6 will drive the support rod 5 to rotate inward until the support rod 5 enters the sliding groove 2. Then, under the action of the limiting ring 10, the three support rods 5 will not rotate, ensuring that the three support rods 5 can be easily folded up, ensuring that the overall device does not take up a lot of space, and is convenient for personnel to use.
