TECHNICAL FIELD

[0001] The present application relates to the technical field of pre-split hole drilling machine positioning, in particular to a pre-split hole drilling machine simple positioning device and method. BACKGROUND

[0002] The key to pre-split blasting effect control lies in the pre-split hole, and the accuracy of drilling machine positioning directly determines the quality of the pre-split hole. Due to the large amount of pre-split blasting engineering and the large number of drilled holes, the positioning efficiency of the drilled holes greatly affects the construction efficiency and even the economic benefits. At present, the drilling method of the pre-split hole drilling machine is usually mainly manual or drilling bent frame. However, these methods still have the following disadvantages: manual drilling with a drilling machine cannot meet the accuracy requirements of construction parameters such as inclination angle, and the construction stability is poor; the drilling bent frame is complex to set up and difficult to move; the simple steel pipe bent frame cannot adjust the inclination angle and other parameters of the drilling machine, and needs to be repeatedly disassembled and reassembled, which leads to low construction efficiency and high cost. Therefore, we provide a pre-split hole drilling machine simple positioning device and method to overcome the above problems. SUMMARY

[0022] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] As shown in the drawings, Figure 1 the present application provides one of the embodiments: a simple positioning method of a presplitting hole drilling machine, the steps of the method comprising:

[0024] The device adopted by the method is specifically a three-positioning structure, wherein the structure of the three-positioning structure is that the hinge 1 is connected with the rod 4, the rod 2 is connected with the rod 3 and the rod 4 on both sides respectively, and the rod 2 and the rod 4 are located in the same plane, and the rod 3 is perpendicular to the plane;

[0025] Initial positioning is achieved by fixing rod 4 using hinge 1;

[0026] Move rod 2 along rod 4, and simultaneously move rod 3 along dotted line 5. The corresponding rod 4 rotates around hinge 1. Adjust the up and down angle of rod 4 to achieve repositioning.

[0027] Move rods 2 and 4 synchronously along the direction of rod 3. Rod 4 rotates around hinge 1 accordingly. Adjust the left and right angles of rod 4 to achieve final positioning. After initial positioning, determining the vertical and horizontal angles of rod 4, and finally fixing rod 4 precisely, the rod 4 is fixed.

[0028] like Figure 2 , Figure 3 , Figure 4 As shown in this embodiment, based on the simplified positioning method for a pre-splitting hole drilling rig, a simplified positioning device for a pre-splitting hole drilling rig is designed, including: a fixed support platform, a screw rod, a screw sleeve fixing fastener one, a screw sleeve fixing fastener two, a bidirectional fixing fastener, and the drilling rig. The fixed support platform is constructed from conventional pipe supports connected by fasteners, providing a support platform for the drilling rig. The screw rod is rigidly connected to the screw sleeve fixing fastener one and connected to the fixed support platform through the screw sleeve fixing fastener two. The bidirectional fixing fastener is connected to the fixed support platform.

[0029] The fixed support platform consists of a rectangular frame structure and stabilizing diagonal braces, connected by fasteners using standard scaffolding pipes to form a preliminary positioning support platform. The threaded sleeve fixing fastener has a threaded sleeve at one end and a movable retaining ring secured by bolts at the other. The threaded sleeve fixing fastener also has a movable retaining ring secured by bolts at the other end and a threaded sleeve at the other end. The bidirectional fixing fastener has movable retaining rings secured by bolts at both the upper and lower ends; the retaining ring size is determined based on actual conditions. The screw is a fully threaded rod, typically 1m in length, with square ends for easy wrench fixing and rotation. All the above types of fasteners and screws are custom-made.

[0030] In the specific implementation of this embodiment, the initial position of the fixed support platform is measured and positioned. The drilling rig is fixed to the fixed support platform using threaded fastener one and bidirectional fasteners, and the drilling rig position is initially determined by measuring and positioning the bidirectional fasteners. The lower end of the bidirectional fastener is loosened, and the upper end of fastener one and the lower end of threaded fastener two are loosened, moving up and down along the fixed support platform with the screw. This allows the drilling rig to rotate and adjust its vertical tilt angle around the bidirectional fasteners as hinge points until the design tilt angle requirement is met, achieving secondary positioning of the drilling rig. The screw is rotated to drive the drilling rig to rotate left and right, adjusting the left and right angles of the drilling rig until the design position requirement is met, achieving final positioning of the drilling rig. Repeating the above steps at new drilling positions can achieve the positioning effect of the pre-splitting hole drilling rig in different construction environments.

[0031] In summary, this embodiment can solve the problems of insufficient drilling accuracy of traditional pre-splitting blasting manual hand-held drilling rigs, the complexity of drilling rig support construction, difficulty in moving, difficulty in fixing and adjusting the direction of the drilling rig's force, and achieve the positioning effect of pre-splitting hole drilling rigs in different construction environments.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
