Description

Technical Field

[0001] This utility model relates to the field of drilling positioning technology, and more specifically, to a novel drilling protection positioning device. Background Technology

[0002] The core purpose of the drilling protection positioning device is to ensure that the drill bit enters the workpiece at a precise angle and position during drilling operations, and to effectively prevent the drill bit from damaging the material at the inlet and outlet. Secondly, the device isolates the operator's hands from the rotating drill bit, reducing the risk of accidental cuts.

[0003] During the drilling protection positioning process, different drill bits are required to drill holes for protection positioning according to different inclination positions. This makes it difficult to apply a single drilling protection positioning method, resulting in poor applicability of drilling protection positioning. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a novel drilling protection positioning device, comprising a positioning frame, wherein two symmetrically arranged rotating shafts are rotatably mounted on the inner wall of the positioning frame, and a protection positioning assembly is provided between the two rotating shafts, the protection positioning assembly comprising: A vertical protective cylinder is fixed between two rotating shafts, and a support rod is fixedly connected to one side of the outer wall of the vertical protective cylinder; The first inclined protective cylinder is fixedly installed at one end of the support rod, and a connecting rod is fixedly connected to the other side of the outer wall of the vertical protective cylinder. A second inclined protective cylinder is fixedly connected to one end of the connecting rod at a position away from the vertical protective cylinder.

[0005] In a preferred embodiment, the first and second inclined protective cylinders are symmetrically arranged with respect to the vertical protective cylinder, and the cross-sectional shape of the vertical protective cylinder is annular.

[0006] In a preferred embodiment, the inner diameter of the vertical protective cylinder is larger than the inner diameter of the first inclined protective cylinder, and the inner diameter of the vertical protective cylinder is larger than the inner diameter of the second inclined protective cylinder.

[0007] In a preferred embodiment, a rotating cap is fixedly connected to one end of the rotating shaft, and the rotating cap is used to drive the rotating shaft to rotate.

[0008] In a preferred embodiment, two threaded bolts are embedded in the upper surface of the positioning frame, the bolts being used to press and lock the rotating shaft.

[0009] In a preferred embodiment, positioning grooves are provided on both sides of the positioning frame; Two lifting blocks are fixedly installed on the lower surface of the positioning frame. Both lifting blocks are used to raise the positioning frame, and a gap groove is provided between the two lifting blocks.

[0010] In a preferred embodiment, the cross-sectional shape of the two lifting blocks and the vertical cross-sectional shape of the spacer groove are rectangular.

[0011] The technical effects and advantages of this utility model are as follows: 1. This utility model adopts a protective positioning component. The rotating cap drives the rotating shaft to rotate, the rotating shaft drives the vertical protective cylinder to rotate laterally, the support rod causes the first inclined protective cylinder to rotate laterally, and at the same time the vertical protective cylinder drives the connecting rod to rotate laterally, the connecting rod drives the second inclined protective cylinder to rotate laterally. In this way, the first inclined protective cylinder, the vertical protective cylinder and the second inclined protective cylinder all rotate laterally to the designated borehole protection, realizing multi-point inclined borehole treatment, and the protective positioning borehole has a wider range of applications, realizing a new type of borehole protective positioning treatment; 2. This utility model increases the stability of the positioning frame by having both feet step on the inside of the two positioning slots respectively. The lifting block can raise the positioning frame, providing sufficient space for stability so that the vertical protective cylinder, the first inclined protective cylinder, and the second inclined protective cylinder can drill holes for different drill bits.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] As attached Figure 1 - Appendix Figure 4 The present invention discloses a novel drilling protection positioning device, which is equipped with a protection positioning component. The protection positioning component enables the first inclined protection cylinder 5, the vertical protection cylinder 3, and the second inclined protection cylinder 7 to rotate laterally to the designated drilling protection position, thereby achieving multi-point inclined drilling treatment and making the drilling protection positioning device more widely applicable. The specific structural configuration of the protection positioning component is as follows.

[0019] In this technical solution, as shown in the appendix Figure 1 - Appendix Figure 3 As shown, two symmetrically arranged rotating shafts 2 are rotatably mounted on the inner wall of the positioning frame 1. A protective positioning assembly is provided between the two rotating shafts 2. The protective positioning assembly includes: a vertical protective cylinder 3, fixed between the two rotating shafts 2, with a support rod 4 fixedly connected to one side of the outer wall of the vertical protective cylinder 3; a first inclined protective cylinder 5, fixedly installed at one end of the support rod 4, with a connecting rod 6 fixedly connected to the other side of the outer wall of the vertical protective cylinder 3, and a second inclined protective cylinder 7 fixedly connected to one end of the connecting rod 6 away from the vertical protective cylinder 3. The first inclined protective cylinder 5 and the second inclined protective cylinder 7 are symmetrically arranged with respect to the vertical protective cylinder 3, and the cross-sectional shape of the vertical protective cylinder 3 is annular. The inner diameter of the vertical protective cylinder 3 is larger than the inner diameter of the first inclined protective cylinder 5, and the inner diameter of the vertical protective cylinder 3 is larger than the inner diameter of the second inclined protective cylinder 7.

[0020] In this technical solution, as shown in the appendix Figure 3 As shown, a rotating cap 8 is fixedly connected to one end of the rotating shaft 2. The rotating cap 8 is used to drive the rotating shaft 2 to rotate. This allows the rotating cap 8 to drive the rotating shaft 2 to rotate, facilitating stable rotation of the rotating shaft 2.

[0021] In this technical solution, as shown in the appendix Figure 3 As shown, two threaded bolts 9 are embedded in the upper surface of the positioning frame 1. The bolts 9 are used to press and lock the rotating shaft 2 so that the bolts 9 can engage with the positioning frame 1. In this way, the bolts 9 press and lock the rotating shaft 2, which causes the rotating shaft 2 to rotate and shift compared to surface A.

[0022] When using this novel drilling protection positioning device, rotating the rotating cap 8 causes the rotating shaft 2 to rotate. The rotating shaft 2 rotates inside the positioning frame 1, causing the vertical protective cylinder 3 to rotate laterally. The vertical protective cylinder 3, in turn, causes the support rod 4 to rotate laterally, which in turn causes the first inclined protective cylinder 5 to rotate laterally. Simultaneously, the vertical protective cylinder 3 causes the connecting rod 6 to rotate laterally, which in turn causes the second inclined protective cylinder 7 to rotate laterally. In this way, the first inclined protective cylinder 5, the vertical protective cylinder 3, and the second inclined protective cylinder 7 all rotate laterally to the designated drilling protection position. Then, rotating the two bolts 9 causes them to engage with the positioning frame 1, thus locking the rotating shaft 2 and fixing its rotation angle. This allows the user to step into the positioning grooves 10 on both sides of the positioning frame 1, increasing the stability of the positioning frame 1. Then, a large drill bit is inserted into the vertical protective cylinder 3 for laterally inclined drilling, followed by a small drill bit inserted into the first inclined protective cylinder 5 for inclined drilling, and then another small drill bit inserted into the second inclined protective cylinder 7 for inclined drilling.

[0023] In this technical solution, as shown in the appendix Figure 4 As shown, positioning slots 10 are provided on both sides of the positioning frame 1; two lifting blocks 11 are fixedly installed on the lower surface of the positioning frame 1, and the two lifting blocks 11 are used to raise the positioning frame 1, and a gap slot 12 is provided between the two lifting blocks 11.

[0024] The cross-sectional shape of the two lifting blocks 11 is rectangular, and the vertical cross-sectional shape of the spacer groove 12 is rectangular.

[0025] When using this novel drilling protection and positioning device, the user steps on the two positioning slots 10 with both feet, which increases the stability of the positioning frame 1. The lifting block 11 can raise the positioning frame 1, so that the spacer slot 12 has enough space to stabilize the vertical protective cylinder 3, the first inclined protective cylinder 5, and the second inclined protective cylinder 7 for drilling different drill bits.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
