Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to a quick fixing device for portable full hydraulic drilling rigs. Background Technology

[0002] Portable fully hydraulic drilling rigs are widely used in field drilling operations such as mine geological exploration and mineral resource surveys. Their stability directly affects drilling accuracy and operational safety. Traditionally, portable fully hydraulic drilling rigs are primarily fixed using ground anchors. This involves drilling holes at the rig's location, inserting ground anchors, pouring cement into the holes, and waiting for the cement to harden (usually over 12 hours). Then, using a fixing chain and drill rod, the rig is connected and fixed to the ground anchor, and finally secured to the horizontal sleepers above using self-tapping wood screws. This method is not only cumbersome, but the fixing chain can loosen under drilling vibrations, causing the rig to shift. Furthermore, the self-tapping wood screws only bear force on one side, making them prone to loosening over time, posing a safety hazard. The long waiting time for the cement to harden also delays drilling operations by at least one day, severely impacting field drilling efficiency.

[0003] To address the aforementioned issues, there is an urgent need to design a portable, fully hydraulic drilling rig fixing device with high fixing efficiency and strong stability to meet the needs of rapid drilling operations in the field of mines. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as long construction time and reduced efficiency in field drilling, by proposing a rapid fixing device for portable fully hydraulic drilling rigs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quick-fixing device for a portable fully hydraulic drilling rig includes a body, which includes a horizontal steel and a longitudinal steel at its bottom, wherein the horizontal steel is welded to the surface of the longitudinal steel and forms a U-shaped cavity in the middle. It also includes a fixing mechanism located below the body, the fixing mechanism including two first sleepers and multiple second sleepers, the second sleepers being laid on top of the first sleepers and perpendicular to the first sleepers, and multiple tensioning members being provided between the first sleepers and the cross steel for connecting and fixing the first sleepers and the cross steel; The surface of the first sleeper abuts against the bottom of the longitudinal steel, and the second sleeper is located between the transverse steel and the first sleeper, with its surface abutting against the bottom of the transverse steel.

[0006] As a further embodiment of this utility model, the tensioning member is a saddle bolt, which is fitted onto the bottom of the first sleeper with its opening facing upward. At least one horizontal plate is fitted onto the top of the saddle bolt, with the bottom of the horizontal plate abutting against the surface of the horizontal steel. Both ends of the top of the saddle bolt are threaded with locking nuts.

[0007] As a further embodiment of this utility model, the locking nut is a hexagonal flange nut with a 30° wedge-shaped inclined thread design.

[0008] As a further embodiment of this utility model, the bottom of the saddle bolt is horizontally positioned and the two sides are perpendicular to the bottom.

[0009] As a further improvement of this utility model, the surface of the second sleeper is fixed with rubber pads by bolts.

[0010] As a further embodiment of this utility model, it also includes support components disposed at both ends of the second sleeper. The support components include through holes disposed near the ends of the second sleeper. The through holes are arranged vertically and vertically and a screw is inserted inside. A support plate is fixedly connected to the bottom of the screw. The bottom of the support plate is located on the same horizontal plane as the bottom of the first sleeper. A washer is fitted around the circumference of the screw and a limit nut is threadedly connected to it. The limit nut is located below the washer, and the surface of the washer abuts against the bottom of the second sleeper.

[0011] As a further embodiment of this utility model, the screw is circumferentially threaded with a fixing nut, which is located above the second sleeper.

[0012] In this application, the following steps are included when using it: 1. On-site leveling: At the mining drilling site, place two first sleepers parallel and spaced apart at the preset drilling rig position, and adjust the spacing and levelness of the first sleepers; 2. Installation of U-bolts: After removing the first sleeper, place multiple sets of square U-bolts on the ground at intervals according to the sleeper layout, with the openings facing upwards. 3. Laying: Replace the two lower first sleepers, press the square U-bolts on the first sleepers firmly, readjust the spacing and level again to ensure the sleepers are stable, and continue to lay the upper second sleepers according to the layout and dimensions of the drilling rig base; 4. Drilling rig positioning: Hoist the portable full hydraulic drilling rig above the fixed mechanism, with the screws at both ends of the square U-bolts passing through both sides of the drilling rig base, and the bottom surface of the drilling rig base fitting against the top surface of the sleeper; 5. Tightening and fixing: Install the horizontal plate and lock nut in sequence on the threaded part of the saddle bolt, tighten symmetrically and gradually until the drill base is tightly fitted with the first sleeper and the second sleeper without any loose gaps, and the drill is fixed.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In one embodiment: Refer to Figures 1-3 A quick-fixing device for a portable full hydraulic drilling rig includes: a body 1, the body 1 including a horizontal steel 3 and a longitudinal steel 4 set at its bottom, the horizontal steel 3 being welded to the surface of the longitudinal steel 4 and forming a U-shaped cavity in the middle, the horizontal steel 3 and the longitudinal steel 4 being used to support and fix the body 1 as a whole. It also includes a fixing mechanism 2 located below the body 1. The fixing mechanism 2 includes two first sleepers 5 and multiple second sleepers 6. The second sleepers 6 are laid on top of the first sleepers 5 and are set perpendicular to the first sleepers 5. Multiple tensioning members are set between the first sleepers 5 and the horizontal steel 3 to connect and fix the first sleepers 5 and the horizontal steel 3. After the first sleepers 5 are laid horizontally, the second sleepers 6 are laid on their surface, and then the first sleepers 5 and the horizontal steel 3 are fixed by the tensioning members. This completely solves the problem of the traditional method (drilling holes) taking a day, and significantly improves the efficiency of mining field drilling operations. The surface of the first sleeper 5 abuts against the bottom of the longitudinal steel 4, and the second sleeper 6 is located between the transverse steel 3 and the first sleeper 5, with its surface abutting against the bottom of the transverse steel 3. This abutting support makes the machine body 1 more stable during use.

[0020] In this utility model, the tensioning component is a U-bolt 8, which is fitted onto the bottom of the first sleeper 5 with its opening facing upwards. At least one horizontal plate 9 is fitted onto the top of the U-bolt 8, with the bottom of the horizontal plate 9 abutting against the surface of the horizontal steel 3. Both ends of the top of the U-bolt 8 are threaded with locking nuts 10. The horizontal plate 9 is made of galvanized steel plate. The horizontal plate 9 and locking nuts 10 are installed sequentially on the threaded part of the U-bolt 8 and tightened symmetrically and gradually until the bottom of the machine body 1 is tightly fitted with the first sleeper 5 and the second sleeper 6 without any loose gaps, thus completing the fixing of the drilling rig.

[0021] In particular, the locking nut 10 is a hexagonal flange nut with a 30° wedge-shaped inclined thread design. The use of the hexagonal flange nut can adapt to the vibration conditions of the drilling rig and play a role in preventing loosening.

[0022] It should be noted that the bottom of the saddle bolt 8 is set horizontally and the two sides are perpendicular to the bottom. The horizontal setting can better fit the bottom of the first sleeper 5.

[0023] In this invention, the surface of the second sleeper 6 is fixed with rubber pads 7 by bolts. The rubber pads 7 can reduce vibration and impact during subsequent use, and at the same time increase friction to prevent slippage.

[0024] In another embodiment: Reference Figure 4The portable full hydraulic drilling rig's quick-fixing device also includes support components set at both ends of the second sleeper 6. The support components include through holes set near the ends of the second sleeper 6, with the through holes extending vertically and a screw 11 inserted inside. A support plate 12 is fixedly connected to the bottom of the screw 11, and the bottom of the support plate 12 is at the same level as the bottom of the first sleeper 5. A washer 14 is fitted around the circumference of the screw 11 and a limit nut 13 is threadedly connected to it. The limit nut 13 is located below the washer 14, and the surface of the washer 14 abuts against the bottom of the second sleeper 6. A fixing nut 15 is threadedly connected to the circumference of the screw 11, and the fixing nut 15 is located above the second sleeper 6. The height of the support plate 12 can be adjusted by adjusting the limit nut 13 to ensure that it is flush with the bottom of the first sleeper 5. Meanwhile, a fixing nut 15 is threadedly connected to the part of the screw 11 above the second sleeper 6. Tightening the fixing nut 15 can fix the screw 11 in the through hole, preventing the screw 11 from moving up and down when the drilling machine is working, and further ensuring the stability of the fixing mechanism 2.

[0025] However, as is well known to those skilled in the art, the working principle and wiring method of the body 1 are commonplace and are all conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0026] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
