Description

Technical Field

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

[0002] The extraction of mineral resources can provide a continuous source of energy for our lives and the development of society. Coal mining can provide energy and electricity resources for power plants and various factories, maintaining the transmission of electricity; the mining of metal mines can obtain various metals, which can be processed into various metal profiles and used to construct buildings, etc.; the development of stone mines can be used for road paving in urban construction and home decoration.

[0003] When conducting exploration in a mining site, drilling is usually carried out. The location of the borehole is determined using equipment such as a total station and GPS. After the location of the borehole is determined, it is marked by marking points. When drilling, the drill bit needs to be aligned with the marked points. Due to the large size of the drill bit and the large volume of the drilling equipment, it is difficult to align the center axis of the drill bit with the marked points. The alignment error by visual inspection is large and can be further improved. At the same time, it is also difficult to determine the verticality of the drill bit, which can also be further improved. Utility Model Content

When drilling and positioning in a mining site, the outer ring 1 can be slipped onto the outside of the drill bit from bottom to top. Then, by rotating the handle 5, the tightening screw 2 is rotated, causing the fixing groove 4 to tighten the drill bit shaft, thus completing the fixing. The operator can move the drill bit above the drilling position and align the point marked by the laser alignment light 7 with the marked drilling point to complete the drill bit positioning work. The positioning is accurate and convenient, improving the ease of use.

[0029] In one embodiment, the outer ring 1 and the lifting ring 10 are arranged coaxially, and the inner diameter of the outer ring 1 is the same as the outer diameter of the drill bit, which improves the stability of the installation. At the same time, the continuous spiral structure of the drill bit edge also prevents the outer ring 1 from tilting and shaking.

[0030] In one embodiment, the circular level 8 is arranged horizontally, and its central axis is parallel to that of the outer ring 1. The inner wall of the outer ring 1 abuts against the outer wall of the drill bit. The circular level 8 indicates the verticality of the drill bit. The operator can observe the position of the bubble in the circular level 8 and adjust the verticality of the drill bit through the drilling machine adjustment mechanism, thereby facilitating the operator to determine the verticality of the drill bit and further improving the drilling accuracy. After the drill bit is positioned, the operator can rotate the handle 5 in the opposite direction to remove the outer ring 1 and perform the drilling operation. It is convenient and simple to use.

[0031] In one embodiment, multiple sets of lifting rods 9 are arranged, and the lifting rods 9 are distributed at equal angles along the central axis of the outer ring 1. The two ends of the lifting rods 9 are fixedly connected to the bottom surface of the outer ring 1 and the top surface of the lifting ring 10, respectively, to improve the stability of the hoisting and fixing.

[0032] In one embodiment, multiple sets of fixing rods 11 are distributed at equal angles along the central axis of the lifting ring 10, and the two ends of the fixing rods 11 are fixedly connected to the fixing ring 12 and the lifting ring 10 respectively, thereby improving the stability of the fixation.

[0033] In one embodiment, the inner diameter of the fixing groove 4 matches the outer diameter of the drill bit spindle, and the inner wall of the fixing groove 4 is roughened to increase friction and thus improve the stability of the clamping.

[0034] Working principle: When positioning a borehole in a mining site, the outer ring 1 can be slipped onto the outside of the drill bit from bottom to top. Then, by rotating the handle 5, the tightening screw 2 is rotated, causing the fixing groove 4 to tighten the drill bit shaft, thus completing the fixing. The operator can move the drill bit above the drilling position and align the point marked by the laser alignment light 7 with the marked drilling point to complete the drill bit positioning. The positioning is accurate and convenient, improving the ease of use. At the same time, the inner wall of the outer ring 1 abuts against the outer wall of the drill bit, and the circular level 8 indicates the vertical status of the drill bit. The operator can observe the position of the bubble in the circular level 8 and adjust the verticality of the drill bit through the drilling machine adjustment mechanism, thus facilitating the operator to determine the vertical status of the drill bit and further improving the accuracy of drilling. After the drill bit is positioned, the operator can rotate the handle 5 in the opposite direction to remove the outer ring 1 and carry out the drilling operation. It is convenient and simple to use.
