Description

Technical Field

[0001] This disclosure relates to the field of mining engineering equipment technology, and in particular to a pry bar protection device for mine roadways. Background Technology

[0002] In underground mine tunneling, drilling and blasting methods are frequently used for excavating rock tunnels. Due to factors such as the hydrology and geological conditions of the underground rock strata, as well as blasting vibrations, the construction safety risks are relatively high. In particular, after blasting, loose rocks are easily generated in the roof and sides of the tunnel. When construction workers perform roughening operations in the bare tunnel with the risk of loose rocks and collapse, the safety risks are extremely high, and safety accidents caused by falling loose rocks and roof collapses occur frequently.

[0003] While existing technologies utilize equipment such as excavator loaders, milling-type tire skidding trolleys, and integrated skidding and repair machines for mine roadways, their core functions are all skidding and cleaning or roadway repair. They do not provide effective solutions for the safety issues associated with manual skidding operations. During manual skidding, the lack of reliable protective devices leaves workers directly exposed to the risk of collapse, compromising their safety. Furthermore, designing dedicated protective equipment would increase procurement costs, and the limited space in underground engineering makes the transportation, storage, and use of such equipment less flexible.

[0004] Based on the above, how to utilize existing mechanical equipment in the tunnels during mining operations to achieve safety protection against scratches is a problem that those skilled in the art need to consider. Utility Model Content

[0005] One of the technical problems this disclosure aims to solve is how to achieve safety protection for prying in roadways during mining tunneling operations, as mentioned above.

[0006] To address the aforementioned technical problems, this disclosure provides a prying protection device for mine roadways, comprising: an excavator; a first protective mechanism, the first protective mechanism including a plurality of first side strips and a first grid mesh, the plurality of first side strips being sequentially connected end-to-end to form a first frame, the edge of the first grid mesh being connected to the first frame, the first frame being detachably connected to the bucket of the excavator, and the first protective mechanism being movable above the prying area of ​​the mine roadway by the excavator's mechanical arm, so that a protective area is formed below the first protective mechanism; a second protective mechanism, the second protective mechanism disposed above the first protective mechanism including a plurality of second side strips and a second grid mesh, the plurality of second side strips being sequentially connected end-to-end to form a second frame, the edge of the second grid mesh being connected to the second frame, the second frame being slidably connected to the first frame to increase the protective area of ​​the protective zone; and a support rod, the top end of the support rod being connected to the first frame, and its bottom end abutting against the bottom plate of the prying area of ​​the mine roadway to provide support for the first protective mechanism.

[0007] In some embodiments, the pry protection device further includes a sliding mechanism, which includes two slides and two sliders. The two slides are respectively disposed on the top walls of two opposite first side strips, and the two sliders are respectively connected to the bottom walls of two opposite second side strips. The two sliders are slidably disposed on the two slides.

[0008] In some embodiments, the sliding mechanism further includes a locking bolt, which passes through a screw hole in the side wall of the slider and abuts against the side wall of the slide rail to lock the slider onto the slide rail.

[0009] In some embodiments, a support foot plate is connected to the bottom end of the support rod.

[0010] In some embodiments, a lighting lamp is installed on the bottom wall of the first frame.

[0011] In some embodiments, a miniature vibration sensor is mounted on the sidewall of the first frame.

[0012] In some embodiments, the support rods include at least two.

[0013] In some embodiments, a walkie-talkie is provided on the support rod.

[0014] In some embodiments, a pressure sensor is also provided on the support rod.

[0015] In some embodiments, a gas detector is also provided on the support rod.

[0016] The above technical solution has at least the following beneficial effects: This disclosure discloses a protective device for the prying of mine roadways. A first protective mechanism is detachably connected to the bucket of an excavator. The excavator's robotic arm moves the first and second protective mechanisms above the prying area in the mine roadway, providing protection for workers below and preventing falling debris from injuring them. The first and second protective mechanisms form a double layer of protection, further enhancing the safety of the prying area. The second protective mechanism is slidably connected to the first, increasing the protected area. By utilizing the existing excavator as a moving and supporting mechanism, this invention solves the problems of existing technologies where separately designed protective equipment increases equipment purchase costs, and the limited underground space results in poor flexibility in the transportation, storage, and use of dedicated equipment.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0027] As mentioned in the background section above, during manual rock-scraping operations in underground mines, reliable protective devices are lacking, leaving workers directly exposed to the risk of collapse and their safety compromised. Designing dedicated protective equipment would increase equipment purchase costs, and the limited space in underground mines makes the transportation, storage, and use of such equipment inflexible. Based on the above, the inventors of this application provide a rock-scraping protection device for mine roadways in one or more embodiments. By detachably connecting a first protective mechanism to the bucket of an excavator, and using the excavator's robotic arm to move the first and second protective mechanisms above the rock-scraping area of ​​the mine roadway, a protective mechanism is formed to protect the workers below, preventing falling debris from injuring them. This solves one or more problems in the prior art.

[0028] To address the aforementioned technical problems, this utility model provides a pry bar protection device for mine roadways, such as... Figure 1-2 As shown, the system includes: an excavator 1; a first protective mechanism 2, which includes multiple first side strips 3 and a first grid mesh 4, the multiple first side strips 3 being connected end to end to form a first frame, the edge of the first grid mesh 4 being connected to the first frame, the first frame being detachably connected to the bucket 5 of the excavator 1, and the first protective mechanism 2 being able to be moved above the skid-edge area of ​​the mine roadway by the mechanical arm 6 of the excavator 1, so that a protective area is formed below the first protective mechanism 2; a second protective mechanism 7, which is set above the first protective mechanism 2 and includes multiple second side strips 8 and a second grid mesh 9, the multiple second side strips 8 being connected end to end to form a second frame, the edge of the second grid mesh 9 being connected to the second frame, the second frame being slidably connected to the first frame to increase the protective area of ​​the protective zone; and a support rod 10, the top end of the support rod 10 being connected to the first frame, and its bottom end abutting against the bottom plate of the skid-edge area of ​​the mine roadway to support the first protective mechanism 2.

[0029] Specifically, the first side strip 3 and the second side strip 8 are made of square steel pipes, and the first grid mesh 4 and the second grid mesh 9 are both formed by multiple flat steel bars arranged in a crisscross pattern. In use, one end of the first frame is fixed to the bucket 5 of the excavator 1 with bolts. Specifically, four bolts can be used to fix one end of the first frame to the four corners of the bucket 5, and the top of the support rod 10 is connected to the other end of the first frame. If the area of ​​the first grid mesh 4 meets the protection area requirements, the first protective mechanism 2 and the second protective mechanism 7 are arranged vertically to form double-layer protection. If the area of ​​the first grid mesh 4 does not meet the protection area requirements, the second frame slides on the first frame, causing the first protective mechanism 2 and the second protective mechanism 7 to be horizontally misaligned, thereby increasing the protection area to meet the requirements. Then, the excavator 1's mechanical arm 6 moves the first protective mechanism 2 and the second protective mechanism 7 above the skid-edge area, and the bottom end of the support rod 10 abuts against the bottom plate of the skid-edge area, forming a support system for the first protective mechanism 2 and the second protective mechanism 7 together with the excavator 1's mechanical arm 6. After the prying operation is completed, the first frame is removed from the bucket 5, and the excavator 1 can continue digging. Furthermore, the top of the support rod 10 is rotatably connected to the first frame. During operation, the support rod 10 is at a 90-degree angle to the first frame and is locked using a self-locking function. After work is completed, the support rod 10 is rotated to be parallel to the first frame and tied together for easy storage.

[0030] Compared with the prior art, the protective device for prying in mine roadways of this application, by detachably connecting the first protective mechanism 2 to the bucket 5 of the excavator, and by using the mechanical arm 6 of the excavator 1 to move the first protective mechanism and the second protective mechanism 7 above the prying area of ​​the mine roadway, forms protection for the prying workers below, preventing the problem of falling rocks from above the prying work area from injuring the workers; the first protective mechanism 2 and the second protective mechanism 7 form a double layer of protection, further improving the safety of the prying work area; the second protective mechanism 7 is slidably connected to the first protective mechanism 2, increasing the protection area; by using the existing excavator 1 as the moving and supporting mechanism, it solves the problems of the prior art, such as the increased equipment purchase cost due to the separate design of dedicated protective equipment, and the poor flexibility in transportation, storage and use of dedicated equipment due to limited underground engineering space.

[0031] In some embodiments, such as Figure 3 As shown, the pry protection device also includes a sliding mechanism, which comprises two slide rails 11 and two sliders 12. The two slide rails 11 are respectively disposed on the top walls of the two opposite first side strips 3, and the two sliders 12 are respectively connected to the bottom walls of the two opposite second side strips 8. The two sliders 12 are slidably disposed on the two slide rails 11. The sliding mechanism enables the second protective mechanism 7 to slide on the first protective mechanism 2 to meet the protection area requirements.

[0032] In some embodiments, such as Figure 3 As shown, the sliding mechanism also includes a locking bolt 13, which passes through a screw hole on the side wall of the slider 12 and abuts against the side wall of the slide rail 11 to lock the slider 12 onto the slide rail 11. After the second protective mechanism 7 slides into place on the first protective mechanism 2, it is locked onto the first protective mechanism 2 by the locking bolt 13, thus avoiding safety problems caused by the second protective mechanism 7 sliding on its own during the prying operation.

[0033] In some embodiments, such as Figure 1 As shown, a support foot plate 14 is connected to the bottom end of the support rod 10. The support foot plate 14 increases the force-bearing area at the bottom end of the support rod 10, thereby enhancing the stability of the support system structure.

[0034] In some embodiments, a lighting lamp (not shown) is installed on the bottom wall of the first frame. The lighting lamp provides sufficient light for the prying operation, solving the problems of reliance on localized lighting from miner's lamps and limited visibility, improving the accuracy of the prying operation, and reducing missed prying or misoperation due to poor visibility. Specifically, multiple lighting lamps can be installed, evenly distributed on the first frame. Furthermore, lighting lamps can also be installed on the bottom wall of the second frame.

[0035] In some embodiments, a miniature vibration sensor (not shown in the figure) is installed on the side wall of the first frame. During the prying operation, the miniature vibration sensor can capture minute vibration data of the roof and surrounding rock in real time. If the vibration frequency exceeds a preset safety threshold, an alarm connected to the miniature vibration sensor will sound an audible and visual alarm to remind the workers to evacuate to a safe area. At the same time, the miniature vibration sensor can also record data such as vibration duration and amplitude, which facilitates subsequent analysis of the stability of the roadway surrounding rock and provides data support for adjusting the prying operation rhythm or support scheme.

[0036] In some embodiments, the support rod 10 includes at least two (not shown in the figure). The two support rods 10 increase the stability and support strength of the support system structure, further ensuring safety.

[0037] In some embodiments, a walkie-talkie (not shown) is installed on the support rod 10. The personnel working on the barbed wire fence can directly communicate with the excavator driver to request adjustments to the safety net's position, and can also report work progress or emergencies to the ground dispatch center in real time. This solves the problems of low efficiency and susceptibility to misjudgment caused by relying on gestures or shouting in traditional operations, enabling real-time collaboration among workers, equipment drivers, and ground dispatchers, thereby improving work efficiency and emergency response speed.

[0038] In some embodiments, a pressure sensor (not shown) is also provided on the support rod 10. The pressure sensor can monitor the load of the accumulated gravel on the first protective mechanism 2 and the second protective mechanism 7, as well as the impact force of falling rocks above, in real time. When the load or impact force exceeds the threshold, the alarm will sound and the staff will evacuate, thereby improving the safety of the device.

[0039] In some embodiments, a gas detector (not shown) is also installed on the support rod 10. When the gas detector detects that the concentration of harmful gas in the work area exceeds the national standard limit, the alarm sounds and the staff evacuates. This function can fill the monitoring gap for sudden leaks of harmful gas during operation after traditional ventilation testing, further ensuring the safety of workers.

[0040] In summary, compared with the prior art, this disclosure provides a prying protection device for mine roadways. By detachably connecting the first protective mechanism 2 to the bucket 5 of the excavator, and using the mechanical arm 6 of the excavator 1 to move the first protective mechanism and the second protective mechanism 7 above the prying area of ​​the mine roadway, it forms protection for the prying workers below, preventing the problem of falling rocks from above the prying area from injuring them. The first protective mechanism 2 and the second protective mechanism 7 form a double layer of protection, further improving the safety of the prying area. The second protective mechanism 7 is slidably connected to the first protective mechanism 2, increasing the protection area. By using the existing excavator 1 as the moving and supporting mechanism, it solves the problems of increased equipment purchase costs and poor transportation, storage, and usage flexibility of dedicated protective equipment in the prior art due to limited underground space. The lighting improves the accuracy of prying operations and reduces missed prying or misoperation caused by poor visibility. The use of miniature vibration sensors, pressure sensors, and gas detectors further ensures the safety of workers. The use of walkie-talkies improves work efficiency and emergency response speed.
