An engineering sampling device for construction supervision

Abstract

The invention discloses an engineering sampling device for construction supervision, which structure comprises a supporting base, a guide rod, a lifting seat, a motor, a worm and a drilling device. The upper end surface of the right side of the supporting base is fixed to the lower end of the guide rod. When soil enters the interior of the drill bit body, the soil conflicts with the pressure plate, and the elastic reset of the telescopic hose and the top spring pushes the pressure plate to move downward, so that the soil is discharged from the interior of the drill bit body as a whole, and the soil is prevented from remaining in the interior of the drill bit body. During the rotation of the drill bit body, the extrusion plate moves in an arc shape on the spring rod and is squeezed into the interior of the flip plate, so that there is space for the soil to enter the bottom of the drill bit body. When the soil fills the interior of the entire drill bit body, the drill bit body stops working. At this time, the elastic reset of the spring rod causes the extrusion plate to pop out of the interior of the flip plate, providing a supporting force for the bottom of the soil in the drill bit body, thereby preventing the soil from falling and ensuring the integrity of the extracted soil discharge.

Description

Technical Field

[0001] The invention relates to the technical field of building supervision, and more specifically, to an engineering sampling device for building supervision. Background Art

[0002] During the construction process, the supervision unit uses an engineering sampling device to extract and test the soil. The engineering sampling device rotates the hollow drill bit on the device, and then extends it into the soil of the construction site, thereby extracting the soil of the construction site into the hollow drill bit, so as to sample and test the local soil. However, after the engineering sampling device extracts the soil into the hollow drill bit, the soil fills the inside of the hollow drill bit, and the air pressure inside the hollow drill bit remains stable, making it difficult to discharge the soil from the hollow drill bit, resulting in soil remaining in the hollow drill bit. At the same time, the soil at the bottom of the hollow drill bit is relatively loose, and it is easy for the soil to fall out of the hollow drill bit during the extraction process, reducing the completeness of the soil sampling.

The soil conflicts with the pressure plate, causing the pressure plate to push the telescopic hose and the top spring upward to contract. When the soil needs to be discharged from the drill bit body, the elastic reset of the telescopic hose and the top spring pushes the pressure plate downward to discharge the soil as a whole from the drill bit body, avoiding soil residue in the drill bit body and ensuring the completeness of soil extraction and discharge.

[0011] 2. When the drill body is rotating, the extrusion plate moves in an arc shape on the spring rod and squeezes into the flip plate, so that there is space at the bottom of the drill body to enter the soil. When the soil fills the entire drill body, the drill body stops working. At this time, the elastic force of the spring rod is reset to pop the extrusion plate out of the flip plate, providing supporting force for the bottom of the soil inside the drill body, thereby preventing the soil from falling and ensuring the integrity of the extracted soil discharge.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

[0022] As attached Figure 1 To Attachment Figure 5 As shown:

[0023] The present invention discloses an engineering sampling device for construction supervision, which structure includes a support base 1, a guide rod 2, a lifting seat 3, a motor 4, a worm 5, and a drilling device 6. The upper end surface of the right side of the support base 1 is fixed to the lower end of the guide rod 2, and the middle part of the guide rod 2 is matched to penetrate the right end of the lifting seat 3. The upper end surface of the lifting seat 3 is fixedly installed with the motor 4. The worm 5 is clearance-matched to penetrate the right end of the lifting seat 3 and is threadedly connected. The motor 4 is internally connected to the drilling device 6 by transmission. The upper left end of the drilling device 6 is fixedly installed on the right end of the lifting seat 3. The drilling device 6 includes a protection frame 61, a belt 62, a pulley 63, a guide block 64, a rotating shaft 65, and a hollow drill bit 66. The left end of the protection frame 61 is fixedly installed on the right end of the lifting seat 3, and a belt 62 is installed inside the protection frame 61. The pulley 63 rotates synchronously with the output end of the motor 4 through the belt 62. The pulley 63 is installed on the upper end of the rotating shaft 65. The guide block 64 is installed in the middle of the rotating shaft 65 with a clearance fit. The guide block 64 is fixedly installed inside the lower end of the protection frame 61, and the lower end of the rotating shaft 65 is welded to the top of the hollow drill bit 66.

[0024] Among them, the hollow drill bit 66 includes a drill bit body 661, a telescopic mechanism 662, and a blocking mechanism 663. The top of the drill bit body 661 is welded to the lower end of the rotating shaft 65, and the top of the telescopic mechanism 662 is fixed to the upper end surface of the drill bit body 661. The blocking mechanism 663 is installed at the bottom of the inner side of the drill bit body 661. The telescopic mechanism 662 is located directly above the blocking mechanism 663. The lower end of the telescopic mechanism 662 matches the inner diameter of the drill bit body 661 to ensure that the lower end of the telescopic mechanism 662 can move up and down inside the drill bit body 661, thereby extracting and squeezing the soil inside the drill bit body 661.

[0025] The telescopic mechanism 662 includes an air guide mechanism 62a, a telescopic hose 62b, a top spring 62c, and a breathable plate 62d. The upper end surface of the air guide mechanism 62a is fixed to the lower end of the telescopic hose 62b, and the upper end of the telescopic hose 62b is fixed to the breathable plate 62d. A top spring 62c is installed inside the telescopic hose 62b. The lower end of the top spring 62c is fixed to the upper end surface of the air guide mechanism 62a, and the upper end of the top spring 62c is fixed to the bottom of the breathable plate 62d. The breathable plate 62d is fixedly mounted on the drill. At the top inner side of the head body 661, the air guide mechanism 62a is located above the blocking mechanism 663. The telescopic hose 62b is of a pleated structure and is made of rubber material with a certain resilience, ensuring that the air guide mechanism 62a moves up and down inside the drill body 661, thereby ensuring that the soil is extracted. A cavity with a wide inlet and a narrow outlet runs through the air permeable plate 62d, which is beneficial for the soil to squeeze out the internal air pressure after entering the drill body 661, thereby ensuring that the air pressure inside the drill body 661 remains balanced.

[0026] Among them, the air guide mechanism 62a includes a pressure plate a1, a rotating block a2, a torsion shaft a3, an opening and closing piece a4, and an air vent a5. The upper end surface of the pressure plate a1 is fixed to the lower end of the top spring 62c, and the rotating block a2 is hinged to the inside of the pressure plate a1 through the torsion shaft a3. The rotating block a2 is installed on the outside of the opening and closing piece a4, and the opening and closing piece a4 is located inside the pressure plate a1. The air vent a5 runs through the inside of the opening and closing piece a4. The rotating block a2, the torsion shaft a3 and the opening and closing piece a4 are each provided with eighteen, and two are in a group, which is conducive to guiding the air pressure inside the drill bit body 661 and preventing soil from entering the telescopic hose 62b, ensuring that the top spring 62c maintains elastic force, thereby driving the pressure plate a1 to press down the soil and quickly discharge the soil from the inside of the drill bit body 661.

[0027] The specific usage and function of this embodiment are as follows:

[0028] In the present invention, the worm 5 is rotated to drive the lifting seat 3 to move smoothly downward along the guide rod 2. When it moves to the bottom of the drilling device 6 and contacts the soil surface, the motor 4 is started to rotate, and the pulley 63 is driven to rotate through the transmission of the belt 62. At this time, the rotation guide of the guide block 64 ensures that the rotating shaft 65 rotates smoothly, thereby driving the drill body 661 to rotate. Then, the worm 5 is slowly rotated to make the drill body 661 extend into the soil. The soil slowly enters the drill body 661 through the blocking mechanism 663. When the soil enters the drill body 661, a certain air pressure is generated, and the air pressure pushes the opening and closing piece a4 to move upward around the torque axis a3. Rotate, thereby discharging the air pressure upward and out of the air permeable plate 62d, ensuring the stability of the air pressure inside the drill bit body 661, so that the soil slowly fills the inside of the drill bit body 661. During the drilling process, the soil conflicts with the pressure plate a1, so that the pressure plate a1 pushes the telescopic hose 62b and the top spring 62c upward to contract, ensuring that the soil fills the entire drill bit body 661. After the extraction is completed, when the soil needs to be discharged from the drill bit body 661, the elastic reset of the telescopic hose 62b and the top spring 62c pushes the pressure plate a1 downward to discharge the entire soil from the drill bit body 661, avoiding soil residue in the drill bit body 661 and ensuring the completeness of the soil extraction and discharge.

[0029] Embodiment 2:

[0030] As attached Figure 6 To Attachment Figure 7 As shown:

[0031] Among them, the blocking mechanism 663 includes an outer ring 63a, a torque rotator 63b, and a flipping mechanism 63c. The outer ring 63a is fixedly installed on the inner bottom of the drill bit body 661. The inner side of the outer ring 63a is connected to the outer end of the flipping mechanism 63c through the torque rotator 63b. There are four torque rotators 63b and flipping mechanisms 63c, and they are distributed in a ring shape on the inner side of the outer ring 63a, which is conducive to the flipping mechanism 63c to flip at the bottom of the drill bit body 661, thereby blocking and releasing the soil at the bottom of the drill bit body 661 to prevent the soil from falling during the extraction process.

[0032] The flipping mechanism 63c includes a flipping piece c1, a spring rod c2, and an extrusion piece c3. The inner side of the flipping piece c1 is fixed to the left end of the spring rod c2. The spring rod c2 penetrates the extrusion piece c3 with a clearance fit. The outer side of the flipping piece c1 is connected to the inner side of the outer ring 63a through a torque rotator 63b. Both the flipping piece c1 and the extrusion piece c3 are fan-shaped structures, and the area of ​​the extrusion piece c3 is smaller than that of the flipping piece c1, so that the extrusion piece c3 can extend into the flipping piece c1 during the rotation process, providing an area for soil to enter the lower end of the drill body 661. After the rotation stops, the spring rod c2 applies elastic force to squeeze the extrusion piece c3 out of the flipping piece c1, thereby applying a supporting force to the bottom of the soil to prevent the soil from falling.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In the present invention, the drill body 661 generates a rotational force during the rotation process, so that the extrusion piece c3 moves in an arc shape on the spring rod c2 and is squeezed into the inside of the flip piece c1, so that there is space at the bottom of the drill body 661 to enter the soil. When the soil fills the entire drill body 661, the motor 4 is powered off and the drill body 661 stops working. At this time, the elastic force of the spring rod c2 is reset to eject the extrusion piece c3 out of the flip piece c1. At this time, the flip piece c1 and the extrusion piece c3 form a ring with a larger area, thereby closing the bottom of the drill body 661 and providing a supporting force for the bottom of the soil inside the drill body 661, thereby preventing the soil from falling. When the soil needs to be discharged, the torque rotator 63b drives the flip piece c1 and the extrusion piece c3 to flip downward, thereby opening the bottom of the drill body 661 to ensure the integrity of the extracted soil discharge.
