Embodiment

[0022] see figure 1 , A mining drilling indicating and stabilizing device, including: a positioning wedge 1, a support arm 2, a movable rod 3, a telescopic spring 4, a cursor indicator 5, a holder 6, a drill bit 7, and a drill rod 8. The positioning wedge 1 is connected with the movable pull rod 3 in the support arm 2 through threads; the support arm 2 is fixedly connected with the holder 6; the cursor indicator 5 is connected with the support arm 2 by a pin shaft.

[0023] Wherein, the positioning wedge 1 is conical, the wedge angle is preferably 30°-60°, and is made of hard alloy steel. The positioning wedge 1 and the support arm 2 are connected by threads and are detachable.

[0024] The support arm 2 is a hollow structure, and a movable tie rod 3 is arranged in the cavity. The front end of the movable tie rod has threads, which can be connected with the positioning wedge 1; The arm moves in the axial direction; a rack 32 is arranged behind the movable pull rod, which form...

Abstract

The invention belongs to the field of mine drilling equipment, and relates to a drilling indicating and steadying device, in particular to a mining drilling indicating and steadying device. The mining drilling indicating and steadying device comprises a positioning wedge, a supporting arm, a clamping device, a drilling bit and a drilling rod. The positioning wedge is in thread connection with a movable pull rod in the supporting arm. The supporting arm is fixedly connected to the drilling rod through the clamping device. One end of a cursor indicator is connected to the supporting arm through a hinge pin while the other end of the cursor indicator is provided with an illuminant which can emit parallel light beams. The illuminant is located at the axis of the drilling rod. Therefore, the mining drilling indicating and steadying device has the following advantages of being simple in structure and easy to operate, improving the drilling positioning precision, reducing drilling positioning time, and improving the construction quality and schedule.

Description

technical field [0001] The invention relates to a drilling indicating and stabilizing device, which belongs to the field of mine drilling equipment, in particular to a mining drilling indicating and stabilizing device. Background technique [0002] Drilling is a common construction method in modern engineering technology, and it is also the basis of construction methods such as geological exploration, gas drainage, bolt support, blasting operations, etc. Accurate and fast drilling according to the design position is to ensure the quality of subsequent construction and progress prerequisites. With the development of modern coal mine construction technology in a more refined direction, the requirements for the accuracy of drilling construction are getting higher and higher. [0003] Precise hole positioning is crucial to the accuracy of drilling construction. However, the existing drilling equipment generally does not have a drilling indicating and stabilizing device, and th...
