Description

Technical Field

[0001] This utility model relates to the field of mining technology, specifically to a mining protection device. Background Technology

[0002] Safety is paramount in mining operations, but existing mining safety equipment has several shortcomings: First, the fixed protective structure makes it difficult to flexibly adjust the protection range and layout according to the actual terrain and changing work areas, failing to meet diverse protection needs. Second, the installation and dismantling of protective nets are inconvenient; traditional nets are mostly welded, making installation and dismantling time-consuming and labor-intensive, and replacement is cumbersome, affecting the progress of mining operations. With the expansion of mining scale and the increasing complexity of the working environment, there is an urgent need for a new type of mining safety equipment that is flexibly adjustable, easy to install, and provides reliable protection. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a mining protection device that solves the problems of simple structure and poor adjustability of existing protection devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mining protection device includes a pair of bases, a pair of uprights fixedly mounted on the top of the bases, a pair of mounting brackets on the opposite sidewalls of the uprights, a main protective net detachably mounted between the mounting brackets, a longitudinally arranged groove on the sidewall of the mounting bracket near the main protective net, the two ends of the main protective net being slidably embedded in the groove, a limiting component above the main protective net, a pair of laterally sliding slides on the front and rear sides of the uprights, the slides being slidable to the left and right sides respectively, the slides having a rectangular frame structure with an internal mounting groove and an open top, a secondary protective net being embedded in the mounting groove, a pair of legs at the bottom of the slides, pulleys at the bottom of the legs, and the slides being connected to the uprights via a sliding component.

[0005] Preferably, the sliding assembly includes a channel fixedly disposed between a pair of columns, and a track is fixedly disposed on the side wall of the slide near the columns. The track is disposed in the channel and slidably connected to the channel. A first positioning hole and a second positioning hole are respectively provided on both sides of the channel. A positioning bolt is screwed to one end of the track. When the slide is in the retracted state, the positioning bolt is inserted into the first positioning hole. When the slide is in the unfolded state, the positioning bolt is inserted into the second positioning hole.

[0006] Preferably, the limiting component includes a limiting beam disposed above the mounting bracket. The limiting beam has a pair of blind holes at both ends. A limiting pin is slidably disposed in the blind holes. One end of the limiting pin is inserted into a limiting hole in the side wall of the column, and the other end is connected to the bottom of the blind hole through a spring. The upper wall of the limiting beam has transverse grooves on both sides that communicate with the blind holes. A lever that passes through the transverse groove is fixedly disposed on the upper wall of the limiting pin.

[0007] Preferably, the mounting groove has a U-shaped structure, and the secondary protective net can be embedded into the mounting groove from top to bottom. The top of both sides of the slide is connected to the secondary protective net by fastening bolts.

[0008] Preferably, the base is provided with mounting holes.

[0009] Preferably, a fixing cone is provided at the bottom of the base.

[0010] Beneficial effects

[0011] This utility model provides a protective device for mining operations, which has the following beneficial effects:

[0012] The main protective netting and the mounting bracket are fitted with grooves to enable detachable installation and easy replacement of the protective netting. The slide can slide laterally, and the secondary protective netting is embedded in the slide. The protection range can be expanded by sliding the slide. When it is necessary to expand the protection area, the slide can be slid to the sides to unfold, and vice versa, to store the slide, adapting to the needs of different working scenarios.

[0013] In the sliding assembly, the sliding connection between the track and the channel allows the carriage to move smoothly. The engagement of the positioning bolts with the first positioning hole and the second positioning hole ensures a stable fixation of the carriage in both the retracted and extended states, preventing accidental sliding. The limiting assembly, through the design of the limiting beam, limiting pin, spring, and lever, can quickly limit the main protective net. Pressing the lever causes the limiting pin to retract into the blind hole, facilitating the installation or removal of the main protective net. Releasing the lever pushes the spring to insert the limiting pin into the column limiting hole, achieving a stable limit on the main protective net.

[0014] The secondary protective net is embedded in the U-shaped mounting groove and connected to the slide frame by fastening bolts, ensuring a secure installation. The mounting holes on the base can be fixed to the ground with bolts, and the bottom fixing cone can be directly inserted into the ground. This dual fixing method ensures that the protective equipment can be installed stably under different geological conditions, improving the overall reliability of the protection.

[0021] By adopting the above technical solution, the two ends of the main protective net 4 are embedded into the grooves of the mounting frame 3 to complete the installation of the main protective net 4. If it is necessary to expand the protection range, push the slide 5 to make the slide 5 slide laterally along the column 2 and unfold the secondary protective net 6; if it is not necessary to expand the protection range, the slide 5 is stored away. The above components provide basic protection for mining operations and the protection range can be flexibly changed according to actual needs.

[0022] In this embodiment, the sliding assembly includes a channel 9 fixedly disposed between a pair of columns 2. A track 10 is fixedly disposed on the side wall of the slide 5 near the column 2.

When the slide 5 is in the retracted state, the positioning bolt 13 is inserted into the first positioning hole 11. When the slide 5 is in the unfolded state, the positioning bolt 13 is inserted into the second positioning hole 12.

[0023] By adopting the above technical solution, when the slide 5 needs to be unfolded, the positioning bolt 13 is loosened, the slide 5 is pushed so that the track 10 slides in the channel 9, and after the slide 5 is moved to the unfolded position, the positioning bolt 13 is tightened so that it is inserted into the second positioning hole 12 to fix the slide 5; when the slide 5 needs to be folded up, the positioning bolt 13 is loosened, the slide 5 is slid to the folded up position, and the positioning bolt 13 is tightened again to be inserted into the first positioning hole 11 to fix it. Through the cooperation of the positioning bolt 13 with different positioning holes, it is ensured that the slide 5 will not move arbitrarily in the folded up and unfolded states, thus ensuring the stability of the protective equipment layout and the protective effect.

[0024] In this embodiment, the limiting component includes a limiting beam 14 located above the mounting bracket 3. The limiting beam 14 has a pair of blind holes at both ends. A limiting pin 15 is slidably disposed in the blind holes. One end of the limiting pin 15 is inserted into a limiting hole on the side wall of the column 2, and the other end is connected to the bottom of the blind hole through a spring 16. The upper wall of the limiting beam 14 has transverse grooves 17 on both sides that communicate with the blind holes. A lever 18 that passes through the transverse grooves 17 is fixedly disposed on the upper wall of the limiting pin 15.

[0025] By adopting the above technical solution, when installing the main protective net 4, press the lever 18 to make the limiting pin 15 retract into the blind hole against the elastic force of the spring 16. At this time, the limiting beam 14 can be removed. After the main protective net 4 is embedded into the groove, release the lever 18. The spring 16 pushes the limiting pin 15 into the limiting hole on the side wall of the column 2 to limit and fix the main protective net 4. When disassembling the main protective net 4, press the lever 18 again to make the limiting pin 15 retract, and the main protective net 4 can be taken out. The limiting component realizes the quick installation and stable limiting of the main protective net 4. The operation is simple and convenient and can be completed without tools.

[0026] In this embodiment, the mounting groove is a U-shaped structure, the secondary protective net 6 can be embedded in the mounting groove from top to bottom, and the top of both sides of the slide 5 is connected to the secondary protective net 6 by fastening bolts 19.

[0027] By adopting the above technical solution, the secondary protective net 6 is embedded into the U-shaped mounting groove of the slide 5 from top to bottom. The fastening bolts 19 are passed through the reserved holes on both sides of the top of the slide 5 and the secondary protective net 6. The fastening bolts 19 are tightened to firmly fix the secondary protective net 6 on the slide 5. The design of the U-shaped mounting groove and the fastening bolts 19 makes the secondary protective net 6 firmly installed and not easy to fall off.

[0028] In this embodiment, the base 1 is further configured to have mounting holes.

[0029] By adopting the above technical solution, the bolts are passed through the mounting holes on the base 1 and matched with the pre-embedded bolt holes or expansion bolts in the ground to fix the protective equipment on the ground.

[0030] In this embodiment, a fixing cone 20 is provided at the bottom of the base 1.

[0031] By adopting the above technical solution, the equipment is fixed on the ground by the friction and embedding force between the fixed cone 20 and the ground.

[0032] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
