Description

Technical Field

[0001] This utility model relates to the field of mining anchor bolt support technology, specifically a mining anchor bolt support device that can be installed quickly. Background Technology

[0002] Mining bolt support is an important support technology used in mining to maintain the stability of underground roadways, mining areas, and other engineering structures. It involves driving bolts into the surrounding rock, utilizing the interaction between the bolts and the surrounding rock to connect unstable rock strata or masses, forming a unified support structure. This improves the self-supporting capacity of the surrounding rock, prevents collapses, spalling, and other accidents, and ensures safe production in the mine.

[0003] Currently, mining anchor bolt support devices rely on the contact between the support frame and the top of the mine pit to extend the anchor bolts into the rock strata at the top of the pit, forming the entire support structure. However, during the installation and use of this support structure, multiple anchor bolts need to be extended one by one from the support frame and then into the rock strata, which is time-consuming and labor-intensive, affecting the actual installation efficiency. Therefore, there is a need to provide an anchor bolt support device that can solve the above-mentioned drawbacks and improve the usage effect. Utility Model Content

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.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-4 As shown, this utility model is a mine anchor bolt support device that can be quickly installed, comprising:

[0025] The anchor bolt support mechanism includes a first support frame 11 and a second support frame 12 symmetrically distributed and attached to the top surface of the roadway. One end of the first support frame 11 and one end of the second support frame 12 are movably connected. Reinforced support structures are provided at equal intervals on the inner sides of the first support frame 11 and the second support frame 12. An anchor bolt body 15 is passed through one end of the first support frame 11 and the second support frame 12 and extends into the top of the mine pit. Elastic bands 19 are provided on the outer sides of the first support frame 11 and the second support frame 12 and abut against one end of the anchor bolt body 15.

[0026] The first support frame 11 and the second support frame 12, together with the reinforced support structure and the anchor bolt body 15, provide support capacity for the top of the mine pit. The movable connection of the first support frame 11 and the second support frame 12 can be easily folded after subsequent use, and the anchor bolt body 15 is supported and limited by the elastic band 19 after it is moved down. When used later, the elastic band 19 can be used to restore the deformation, and multiple anchor bolt bodies 15 can be reset at the same time, which saves time and effort and is simple and convenient.

[0027] The outer ends of the first support frame 11 and the second support frame 12 are both fixed with sleeves 17, and the corresponding sleeves 17 are fitted with sleeve posts 18, the outer ends of the sleeve posts 18 are bolted to the four corners of the elastic band 19.

[0028] The sleeve 17 and the sleeve column 18 fit together to connect the first support frame 11, the second support frame 12 and the elastic band 19.

[0029] Both the first support frame 11 and the second support frame 12 have through openings on one side, and the anchor rod body 15 extends out of the through openings.

[0030] A limiting head 110 is threaded on the upper part of the inner wall of the opening, and one end of the limiting head 110 abuts against the other end of the anchor rod body 15.

[0031] The through-hole is a cavity structure, which allows the upper end of the anchor bolt body 15 to pass through the first support frame 11 and the second support frame 12 and extend into the top of the roadway. The first support frame 11 and the second support frame 12 are connected by a movable method. After folding inward to form a certain angle difference, the anchor bolt body 15 in the unused state can move inward, that is, the upper part of the anchor bolt body 15 does not extend out of the through-hole. At this time, the lower end of the anchor bolt body 15 abuts against the elastic band 19. Then, the abutting head 110 is inserted into the through-hole to abut against the upper end of the anchor bolt body 15, ensuring the stability of its structure.

[0032] Movable blocks 13 are provided both inside and outside at the joint of the first support frame 11 and the second support frame 12. The ends of adjacent movable blocks 13 pass through the first support frame 11 and the second support frame 12 and are provided with locking pins 14.

[0033] The locking column 14, together with the movable block 13, connects the first support frame 11 and the second support frame 12, ensuring that the angle is adjustable while also ensuring the stability of the structure after the angle is adjusted.

[0034] Working principle: During the support of the top of the mine pit, the first support frame 11 and the second support frame 12, which are in a folded state, are unfolded in advance, that is, the locking column 14 is unscrewed. At this time, the elastic band 19, after the force is released, returns to its deformation. Through the action of multiple anchor rods 15, multiple anchor rods 15 extend out of the opening. That is, the upper part of the anchor rod 15 passes through the first support frame 11 and the second support frame 12 and extends into the anchor hole on the top of the roadway. The two are anchored to each other. Then, the nut is locked near the opening of the anchor rod 15. With the resistance of the first support frame 11 and the second support frame 12, the two are fixed. After the first support frame 11 and the second support frame 12 are unfolded and at a horizontal relative angle, the sleeve column 18 is removed from the inside of the sleeve 17, that is, the elastic band 19 is disassembled. When folding and storing later, the above steps are reversed.

[0035] This solution allows for the convenient and quick extension of multiple anchor bolts 15 into the opening, eliminating the need for manual removal and installation of each anchor bolt 15 individually. This saves time and effort, improving usability and operational efficiency.

[0036] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:

[0037] The enhanced support structure includes threaded tubes 161 symmetrically and equidistantly fixed on the opposite inner sides of the first support frame 11 and the second support frame 12. Threaded columns 162 are provided with internal threads in the threaded tubes 161, and connecting blocks 163 are fixed to the outer ends of the threaded columns 162. An enhanced support column 165 is provided between the opposite connecting blocks 163;

[0038] The enhanced support column 165 is arranged in a "ji" shape, and threaded rings 164 are provided with threads at the ends of the enhanced support column 165, and are threadedly extended into one end of the connecting block 163;

[0039] The threaded rings 164 dock and install the connecting blocks 163 and the enhanced support column 165. Then, through the threaded connection between the threaded columns 162 and the threaded tubes 161, the enhanced support column 165 is connected and installed with the first support frame 11 and the second support frame 12. The enhanced support column 165 can be adjusted at multiple angles under threaded rotation to adapt to and fit the top surface of the mine pit, fully ensuring the stability of the support.

[0040] Working principle: During the above process of supporting the top of the mine pit, the angle of the enhanced support column 165 at the corresponding position can be adjusted adaptively as required, that is, applying a force to the enhanced support column 165 at this position, and rotating and adjusting it to the angle that fits the top of the mine pit under threaded rotation. Subsequently, repeat the above support installation steps.

[0041] In this solution, the original plate-shaped support structure inside the first support frame 11 and the second support frame 12 is replaced with multiple enhanced support columns 165 provided with threads. On the one hand, the damaged structure can be disassembled and replaced independently to save the use cost. On the other hand, the required angle can be adjusted by threaded rotation to always adapt to the support surface of different mine pit tops, further improving the use effect.
