Specific implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Refer to Figures 1 - 3 , a sampling device for engineering quality inspection, including a vehicle body 1 symmetrically installed with universal wheels 14. On the front side of the vehicle body 1, limit supports 11 are symmetrically installed for restricting the forward movement of the vehicle body 1. The vehicle body 1 is fixedly installed with a push handle 18 for pushing the vehicle body 1 forward, and an anti-slip rubber is installed at the end of the push handle 18 for better gripping.

[0024] A drilling mechanism for drilling and sampling is fixedly installed on the vehicle body 1. The drilling mechanism includes a base bearing platform 2 fixedly installed on the surface of the vehicle body. Sliding grooves 8 corresponding to the rotating motor 7 are symmetrically arranged on the base bearing platform 2. At the same time, a rotating motor 7 is correspondingly arranged on the sliding groove 8. The bottom flange of the rotating motor 7 is fitted with the sliding groove 8 and can slide left and right in the sliding groove 8. The output end of the rotating motor 7 is welded with a hollow cylinder 9. When the rotating motor 7 is started, the output end of the rotating motor 7 will drive the hollow cylinder 9 to rotate. Also, because a sampling drill bit 10 that movably penetrates the front end of the vehicle body 1 and is used for drilling and sampling is welded to the end of the hollow cylinder 9, the rotating motor 7 will drive the sampling drill bit 10 to rotate. At the same time, because a telescopic cylinder 19 is fixedly installed in the hollow cylinder 9, the output end of the telescopic cylinder 19 is fixedly installed with a piston 20, and the piston 20 is slidably sleeved in the sampling drill bit 10. Therefore, when the sample enters the inside of the sampling drill bit 10, the output end of the telescopic cylinder 19 will drive the piston 20 to push out the sample.

[0025] The drilling mechanism further includes a storage component arranged on the vehicle body 1 and used for collecting building samples. The storage component includes a storage box 12 fixedly installed at the front end position of the vehicle body 1 and corresponding to the sampling drill bit 10. When the output end of the telescopic cylinder 19 drives the piston 20 to push out the sample in the sampling drill bit 10, it just falls into the storage box 12. At the same time, a handle 13 is fixedly installed on one side of the storage box 12, which can conveniently transfer the storage box 12 together with the sample.

[0026] A driving mechanism for driving the drilling mechanism to move is fixedly installed on the vehicle body 1, and the driving mechanism includes a driving motor 3 fixedly installed on the vehicle body 1, and a ball screw 4 rotatably installed on the vehicle body 1 is fixedly connected to the output end of the driving motor 3, and a support pad 5 for supporting the ball screw 4 is fixedly installed on the vehicle body 1, and the support pad 5 is rotatably connected to the ball screw 4, so when the driving motor 3 is started, the output end of the driving motor 3 drives the ball screw 4 to rotate, and at the same time, a connecting plate 6 with a moving nut installed inside is slidably sleeved on the ball screw 4, so when the ball screw 4 rotates, the connecting plate 6 will move horizontally, and at the same time, the connecting plate 6 is fixedly connected to the rotating motor 7, so it will drive the rotating motor 7 to move horizontally;

[0027] The driving mechanism also includes a limiting component arranged on the vehicle body 1 and used to fix the universal wheel 14. The limiting component includes a limiting pad 15 hinged on the rear end of the vehicle body 1. When the vehicle body 1 moves to the specified position, the limiting pad 15 is lowered, and the limiting pad 15 is stuck under the universal wheel 14 to play a limiting role. At the same time, a limiting plate 16 for limiting the limiting pad 15 is rotatably installed at the rear end of the vehicle body 1. When the limiting pad 15 is lowered, the limiting pad 15 can be fixed by the limiting plate 16 to prevent the limiting pad 15 from moving. A fixed hook lock 17 is fixedly installed on the rear side of the vehicle body 1. When the limiting pad 15 is not in use, the limiting pad 15 can be rotated to the fixed hook lock 17 for fixation to prevent it from affecting the movement of the vehicle body 1.

[0028] It should be noted that the specific models and specifications of the motors and cylinders need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0029] The functional principle of the utility model can be explained through the following operation modes:

[0030] When the device is ready to drill a building sample, the vehicle body 1 is first moved to the front of the wall, and the limit support 11 is used to support the wall, and then the drive motor 3 is started, and the drive motor 3 drives the ball screw 4 to rotate. At the same time, the rotation of the ball screw 4 drives the connecting plate 6 to move forward through the moving nut, thereby driving the rotating motor 7 to move forward;

[0031] The rotating motor 7 is started, and in the process of moving forward, the rotating motor 7 drives the empty cylinder 9 to realize spiral forward movement. At the same time, the empty cylinder 9 drives the sampling drill bit 10 to move synchronously, thereby realizing the sampling of the wall.

[0032] After sampling is completed, the telescopic cylinder 19 in the empty tube 9 drives the piston 20 to push out the building sample in the sampling drill bit 10, so that the building sample falls into the storage box 12, thereby retaining the building sample.

[0033] As described above, it is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
