Description

Technical Field

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

[0002] Concrete core samples are drilled directly from structural concrete. After processing, the core samples are subjected to compressive strength testing. This method is generally recognized as a relatively intuitive and reliable test method for testing concrete strength. For coring methods and technical operations, please refer to the "Technical Regulations for Testing Concrete Strength by Core Drilling" officially promulgated by my country.

[0003] Existing Chinese patent CN217930892U discloses a concrete coring device, which moves a sliding seat to a suitable position, presses a push rod with a pressure rod, and fixes the sliding seat with a locking member. Then, the driving motor is restarted to drive the lifting seat to continue to move upward. At this time, the drill seat and the coring drill bit will move upward under the drive of the lifting seat, while the push rod is restricted by the limiter and is located in place and cannot move upward. Therefore, the push plate can push the concrete core sample out of the coring drill bit.

[0004] However, when taking out the core sample, the above-mentioned concrete drilling and coring equipment still needs to manually operate the sliding seat and other structures, and after the core sample is taken out from the coring drill bit, the sliding seat needs to be operated again to allow the push plate to reset under the action of the spring, which increases the operating process and the manual workload. Utility Model Content

[0005] The purpose of the utility model is to provide a concrete drilling and coring device to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a concrete coring device, comprising a box body, a sampling port is provided at the bottom of the box body, and a sampling mechanism is provided inside the box body;

[0007] The sampling mechanism includes a lifting plate and a push rod. A lifting component is provided between the lifting plate and the interior of the box. The inner wall of the lifting plate is rotatably connected to a hollow tube through a bearing. A hollow drill bit is fixedly installed at the bottom of the hollow tube. The interior of the hollow drill bit is connected to the interior of the hollow tube. A motor 1 is fixedly installed at the bottom of the lifting plate. A rotating shaft 1 is fixedly installed at the output end of the motor 1. A gear 2 is fixedly installed on the outer wall of the rotating shaft 1. The gear 2 is engaged with a gear 1. The gear 1 is fixedly installed on the hollow tube. The push rod is fixedly installed on the top inner wall of the box. The bottom end of the push rod passes through the hollow tube and the hollow drill bit, and the axes of the push rod, hollow tube and hollow drill bit coincide.

[0008] Furthermore, the lifting component includes motor 2 and a limiting slide. Motor 2 is fixedly mounted on the top inner wall of the box. Screw rod 1 is fixedly mounted on the output end of motor 2. The outer wall of screw rod 1 is threadedly connected to the inner wall of the lifting plate. The limiting slide is fixedly mounted on the left and right inner walls of the box. The limiting slide is slidably arranged in a slide groove on the lifting plate.

[0009] Furthermore, a material taking port is provided on the front of the box body, the material taking port is close to the bottom of the box body, and a material taking box is placed inside the box body.

[0010] Furthermore, a rack is fixedly installed on the back of the lifting plate, and the rack is engaged with gear three. The inner wall of the gear three is fixedly installed with screw rod two, and the outer wall of the screw rod two is threadedly sleeved with a movable plate. The inner wall of the movable plate is slidably provided with a sliding rod, and the left and right ends of the sliding rod are fixedly connected to the inner wall of the box. The outer wall of the movable plate is adsorbed with a magnet plate, and there are two magnet plates, which are symmetrically distributed about the movable plate. The magnet plate is fixedly installed on the back of the material box.

[0011] Furthermore, universal wheels are fixedly installed on the bottom of the box, and there are four universal wheels, which are respectively located at the four corners of the bottom of the box.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The lifting plate is driven up and down by the lifting component, which in turn drives the hollow drill bit up and down, so that the hollow drill bit extends from the sampling port, and then samples the concrete. After the hollow drill bit takes out the core sample and rises and resets, the core sample in the hollow drill bit contacts the push rod and is pushed out of the hollow drill bit by the push rod, thus realizing the removal of the core sample without manual operation;

[0015] 2. Through the meshing of the rack and gear 3, when the lifting plate moves downward and drives the rack downward, the rack pushes gear 3 to rotate, and then drives screw 2 to rotate, so that the movable plate moves to the left and is staggered with the sampling port, hollow drill bit and other structures. When the lifting plate moves up and drives the rack upward, the rack drives gear 3 to rotate in the opposite direction, so that the movable plate moves to the right, and drives the material box to the bottom of the hollow drill bit to receive the core sample pushed out by the push rod. No manual operation is required during the sample receiving process, which improves safety and saves labor. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom end of the push rod 409 passes through the hollow tube 403 and the hollow drill bit 404. The axes of the push rod 409, the hollow tube 403, and the hollow drill bit 404 coincide with each other, and are driven by gear 1 407 and gear 2 408, so that when the motor 1 405 drives the rotating shaft 1 406 to rotate, it can drive the hollow tube 403 to rotate, and the rotation of the hollow tube 403 drives the hollow drill bit 404 to rotate, and the lifting plate 401 is driven to rise and fall by the lifting component 402, thereby driving the hollow drill bit 404 to rise and fall, so that the hollow drill bit 404 extends from the sampling port 2, and then the concrete is sampled. A push rod 409 is provided passing through the hollow tube 403 and the hollow drill bit 404. After the hollow drill bit 404 takes out the core sample, it rises and resets, and the core sample in the hollow drill bit 404 contacts the push rod 409 and is pushed out of the hollow drill bit 404 by the push rod 409, thereby realizing the removal of the core sample, without manual operation, and with simple steps;

[0024] The lifting component 402 includes a second motor 4021 and a limiting slide 4023. The second motor 4021 is fixedly mounted on the top inner wall of the box body 1. A screw rod 1 4022 is fixedly mounted on the output end of the second motor 4021. The outer wall of the screw rod 1 4022 is threadedly connected to the inner wall of the lifting plate 401. The limiting slides 4023 are fixedly mounted on the left and right inner walls of the box body 1. The limiting slides 4023 are slidably arranged in the slide grooves on the lifting plate 401. The limiting slides 4023 are provided to limit the lifting plate 401 so that the lifting plate 401 can only move up and down relative to the box body 1. The second motor 4021 drives the screw rod 1 4022 to rotate, so that the lifting plate 401 moves up or down.

[0025] The front of the box body 1 is provided with a material taking port 3, which is close to the bottom of the box body 1. A material taking box 5 is placed inside the box body 1. The material taking box 5 is provided to receive the core sample pushed out by the push rod 409. The material taking port 3 is provided to take out the material taking box 5.

[0026] A rack 11 is fixedly installed on the back of the lifting plate 401, and the rack 11 is engaged with a gear 3 10. A screw rod 2 9 is fixedly installed on the inner wall of the gear 3 10. A threaded sleeve on the outer wall of the screw rod 2 9 is provided with a movable plate 7. A slide rod 8 is slidingly provided on the inner wall of the movable plate 7. The left and right ends of the slide rod 8 are fixedly connected to the inner wall of the box body 1. A magnet plate 6 is adsorbed on the outer wall of the movable plate 7. There are two magnet plates 6, and they are symmetrically distributed about the movable plate 7. The magnet plate 6 is fixedly installed on the back of the material box 5. The material box 5 is connected to the movable plate 7 by adsorbing the magnet plate 6 on the movable plate 7, so that the movable plate 7 can drive the material box 5 to move synchronously when it moves left and right. When taking out the material box 5, it is only necessary to pull the material box 5 forward. The rack 11 and the gear three 10 are engaged, so that the lifting plate 401 moves down and drives the rack 11 to move down. The rack 11 pushes the gear three 10 to rotate, and then drives the screw rod 2 9 to rotate, so that the movable plate 7 moves to the left and is staggered with the sampling port 2, the hollow drill bit 404 and other structures. When the lifting plate 401 moves up and drives the rack 11 to move up, the rack 11 drives the gear three 10 to rotate in the opposite direction, so that the movable plate 7 moves to the right, and drives the material box 5 to the right under the hollow drill bit 404 to receive the core sample pushed out by the push rod 409. No manual operation is required during the sample receiving process, which improves safety and saves labor.

[0027] Universal wheels 12 are fixedly installed at the bottom of the box 1. There are four universal wheels 12, which are respectively located at the four corners of the bottom of the box 1. The universal wheels 12 are used to move the box 1;

[0028] An L-shaped plate 13 is fixedly installed on the outer wall of the box body 1, and a threaded rod 14 is threadedly connected to the inner wall of the L-shaped plate 13. The bottom end of the threaded rod 14 is rotatably connected to a shock-absorbing pad 15 through a bearing. When sampling, the threaded rod 14 is rotated so that the threaded rod 14 reaches the shock-absorbing pad 15 and moves down. The shock-absorbing pad 15 moves down and contacts the ground, thereby stabilizing the box body 1.

[0029] Working principle: When in use, move the box body 1 to the sampling position, rotate the threaded rod 14 so that the threaded rod 14 drives the shock-absorbing pad 15 to move downward, and after the shock-absorbing pad 15 contacts the ground, stabilize the box body 1, and then turn on the motor 2 4021 to drive the screw rod 1 4022 to rotate. The rotation of the screw rod 1 4022 causes the lifting plate 401 to move downward, thereby driving the hollow tube 403 to move downward. The downward movement of the hollow tube 403 drives the hollow drill bit 404 to move downward and extend out from the sampling port 2. Turn on the motor 1 405 to drive the rotating shaft 1 406 to rotate, thereby driving the gear 2 408 to rotate. The rotation of the gear 2 408 drives the gear 1 407 to rotate, thereby driving the hollow tube 403 to rotate. The rotation of the hollow tube 403 drives the hollow drill bit 404 to rotate to sample the concrete. After sampling, turn on the motor 2 4021 in reverse to make the lifting plate 401 rise, thereby The hollow drill bit 404 rises. After the hollow drill bit 404 rises to a certain height, the bottom end of the push rod 409 contacts the core sample in the hollow drill bit 404. At this time, the hollow drill bit 404 continues to rise and the push rod 409 can push the core sample out of the hollow drill bit 404, realizing automatic material unloading. When the lifting plate 401 moves down and drives the rack 11 to move down, the rack 11 drives the gear three 10 to rotate, and then drives the screw rod 2 9 to rotate, so that the movable plate 7 moves to the left and is staggered with the sampling port 2, the hollow drill bit 404 and other structures. When the lifting plate 401 moves up and drives the rack 11 to move up, the rack 11 drives the gear three 10 to rotate in the opposite direction, so that the movable plate 7 moves to the right, and drives the material box 5 to the right below the hollow drill bit 404 to receive the core sample pushed out by the push rod 409. No manual operation is required during the sample receiving process, which improves safety and saves labor.

[0030] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
