Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a deviation prevention device for drilling. Background Art

[0002] Drilling refers to the engineering operation of drilling holes in the ground with a drilling rig. It is widely used in geological exploration, mineral resource exploration, engineering construction and other fields. During the drilling work, an anti-drift device is needed to limit the drill bit to prevent the direction of the drill bit from deviating during the drilling process and affecting the drilling effect of the equipment.

[0003] Most of the existing anti-deviation devices are placed directly on the ground. During the operation of the drill bit, the anti-deviation device is easily moved due to excessive rotational force. Most of the current solutions to this movement use a counterweight to press to increase stability. However, when the force is too large, the position will still move, affecting the drilling effect. To this end, in response to the above defects, the present application proposes an anti-deviation device for drilling. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1.

[0020] Before work, the rotating handle 203 is first rotated to drive the spiral drill 201 to rotate, so that the spiral drill 201 is drilled into the ground through the structure of the pointed head 202 and the spiral drill 201. When the four mounting components 2 are all installed under the ground, the base plate 1 can be fixed to fix the equipment to the ground, thereby increasing the stability of the equipment and preventing the equipment from moving during work and affecting the stability of the equipment.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a cylinder 3 is installed at the upper end of the base plate 1, and a clamping and positioning component 4 is connected to the side of the cylinder 3 close to the central axis of the base plate 1, and an auxiliary positioning component 5 is arranged at the upper end of the clamping and positioning component 4.

[0022] like Figure 3 As shown, the clamping and positioning assembly 4 includes a first connecting plate 401, a connecting rod 402 and a connecting side rod 403, and the first connecting plate 401 is connected to the connecting rod 402 on one side close to the bottom plate 1, and the connecting rod 402 is connected to the connecting side rod 403 on one side away from the first connecting plate 401, the clamping and positioning assembly 4 also includes a first mounting plate 404, a first clamping plate 405 and a first rolling ball 406, and the first mounting plate 404 is connected to the one side of the connecting side rod 403 away from the connecting rod 402, and the first clamping plate 405 is connected to the one side of the first mounting plate 404 away from the connecting side rod 403, and the first rolling ball 406 is embedded inside the first clamping plate 405;

[0023] The first rolling ball 406 facilitates the rotation and lifting of the drill rod on the inner side of the first clamping plate 405, and the connecting side rod 403 facilitates the connection of the four corners of the first mounting plate 404, thereby increasing the stability of the connection between the first mounting plate 404 and the connecting rod 402, and increasing the stability of the connection between the first clamping plate 405 and the drill rod.

[0024] like Figure 3 As shown, the auxiliary positioning assembly 5 includes a second connecting plate 501, a pressure sensor 502, a spring 503 and a guide rod 504, and the pressure sensor 502 is installed in the middle of the side of the second connecting plate 501 close to the central axis of the bottom plate 1, the side of the pressure sensor 502 away from the second connecting plate 501 is connected to the spring 503, and the upper and lower sides of the second connecting plate 501 are penetrated by the guide rod 504, the auxiliary positioning assembly 5 also includes a second mounting plate 505, a second clamping plate 506 and a second rolling ball 507, and the side of the spring 503 away from the pressure sensor 502 is connected to the second mounting plate 505, the side of the second mounting plate 505 away from the spring 503 is connected to the second clamping plate 506, and the second rolling ball 507 is embedded in the second clamping plate 506;

[0025] The compression structure of the spring 503 is detected by the pressure sensor 502, and the width of the drill rod is detected by the second clamping plate 506, so that the first clamping plate 405 can be controlled to match the width of the drill rod, which is convenient for the equipment to better limit the drill rod and prevent the drill bit from running off the track during operation.

The second rolling ball 507 facilitates the rotation and lifting of the drill rod on the inner side of the second clamping plate 506.

[0026] Working principle: first, place the equipment at the position where drilling is required, and then rotate the rotating handle 203 respectively, thereby driving the spiral drill 201 to rotate, fix the base plate 1 to the ground through the spiral drill 201 and the pointed head 202, and then insert the drilling drill bit into the base plate 1, then open the cylinder 3 to drive the first clamping plate 405 to hold the drill rod and position the drill rod, and use the first rolling ball 406 to facilitate the drill rod to rotate and lift on the inner side of the first clamping plate 405, and use the second rolling ball 507 to facilitate the drill rod to rotate and lift on the inner side of the second clamping plate 506, and then the drilling device works. When the outer diameter of the drilling rod changes, it will push the second clamping plate 506, so that the second mounting plate 505 compresses the spring 503, so that the data of the pressure sensor 502 changes, thereby controlling the cylinder 3, driving the first clamping plate 405 to move, so that the first clamping plate 405 can match the width of the drill rod, so that the first clamping plate 405 will not affect the lifting of the drill rod.
