Description

Technical Field

[0001] This utility model relates to the field of static blasting technology in ore mining, and in particular to a drilling protection device for static blasting areas in mountainous regions. Background Technology

[0002] Ores have a wide range of industrial applications. For example, in construction, large quantities of crushed stone are needed as aggregate for concrete. Ores are obtained through blasting in mines, and current blasting methods are mainly divided into explosive blasting and static blasting. Static blasting primarily uses hydraulic principles to further crush the ore blasted from the mine.

[0003] Static blasting methods can be carried out using hydraulic blasting rock splitters. Depending on the operating method, these are divided into large-scale blasting rock splitters and manual small-scale blasting rock splitters. Large-scale blasting rock splitters (mainly mounted on tracked machines) are primarily designed for large ores; their advantage is their ability to break up large ores, but their disadvantage is poor maneuverability. Handheld small-scale blasting rock splitters, on the other hand, offer greater flexibility and are mainly used for blasting and splitting medium-sized ores. Large-scale blasting rock splitters have built-in drilling equipment. During the drilling process, the operator is located in the cab, so even if a large amount of flying rock is generated, the impact on the operator's safety is minimal.

[0004] During blasting operations, small, handheld blasting and splitting machines are frequently used (they offer high mobility and flexibility, allowing for further splitting of large ore chunks within the blasted rock pile, where large equipment cannot access the area and manual secondary blasting is necessary). When drilling blasting holes, operators use a handheld drill to create holes in the ore, then insert the hydraulic blasting and splitting equipment into these holes. During the drilling process, because operators are too close to the work area, the high-speed rotating drill bit generates a large amount of debris as it drills into the hard ore, causing debris to fly everywhere and seriously affecting the safety of the operators.

[0005] Furthermore, the process of drilling blasting holes often involves creating multiple holes in the ore and using multiple splitting devices in coordination to split the ore. This arduous drilling operation further increases the likelihood of operators being struck by flying rocks during the drilling process. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a drilling protection device for static blasting zones in mountainous areas.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A drilling protection device for mountain static blasting zones, including a blasting drilling cover mechanism;

[0009] The blasting drilling cover mechanism includes an inner anti-splash stone cover structure covering the drilling position; and a frame structure disposed on the outside of the inner anti-splash stone cover structure.

[0010] The inner splash guard structure is slidably connected to the frame structure via a spring lifting structure;

[0011] The inner splash guard structure includes a guard body, on which a pedal for elastically raising and lowering the guard body is fixedly connected.

[0012] Preferably, the shape of the cover is conical;

[0013] The top of the cover is fixedly connected to an upper top opening plate, and the upper top opening plate has a through hole;

[0014] The drill rod with the hole is inserted through the through hole.

[0015] Preferably, a pair of spaced-apart mounting rods are fixedly connected to the side walls on both sides of the upper top plate;

[0016] The outer ends of the mounting rods are slidably connected to spring lifting structures.

[0017] The spring lifting structure includes a spring sleeve rod, with an upper spring seat and a lower spring seat fixedly connected to the top and bottom of the spring sleeve rod, respectively.

[0018] The outer end of the mounting rod is fixedly connected to a sliding sleeve structure that is slidably connected to the spring sleeve rod, and an upper spring and a lower spring are respectively sleeved on the upper and lower sides of the spring sleeve rod.

[0019] The two ends of the upper spring are fixedly connected to the top of the upper spring seat and the sliding sleeve structure, and the two ends of the lower spring are fixedly connected to the bottom of the lower spring seat and the sliding sleeve structure, respectively.

[0020] Preferably, the sliding sleeve structure includes a sliding sleeve slidably connected to the spring sleeve rod, and an upper annular flange and a lower annular flange are welded to the top and bottom of the sliding sleeve, respectively. The bottom of the upper spring is fixedly connected to the upper annular flange, and the bottom of the lower spring is fixedly connected to the lower annular flange.

[0021] Preferably, the frame structure includes an upper frame rod and a lower frame rod disposed below the upper frame rod;

[0022] The upper frame rod and the lower frame rod are fixedly connected by several connecting rods;

[0023] The top of the upper spring seat and the bottom of the lower spring seat are respectively fixedly connected to sliding sleeves that are slidably connected to the upper frame rod and the lower frame rod.

[0024] Preferably, a plurality of drill rod structures are installed on the lower frame rod.

[0025] Preferably, the drill rod structure includes a main drill rod that is slidably connected to the lower frame rod, and the lower side of the main drill rod is threadedly connected to an adjusting nut that supports the bottom of the lower frame rod.

[0026] Preferably, an adjusting rod is threadedly connected to the bottom of the main drill rod;

[0027] The bottom of the adjusting rod is a conical tip;

[0028] The adjusting rod has a hexagonal convex structure integrally formed.

[0029] Preferably, an outer shield is fitted on the outer side of the inner splash guard structure;

[0030] The outer shield is fastened to the mounting rod by several bolts;

[0031] The outer cover has several weight-reducing holes.

[0032] This utility model has the following beneficial effects:

[0033] 1. By covering the drilling area with a blasting drilling hood mechanism, even if flying rocks are generated, they will impact the blasting drilling hood mechanism, thereby increasing the safety of the drilling operation. This solves the problem that during operation, when hard ores are subjected to the action of the drill rod of a high-speed rotating drill, the flying rocks (splashing rocks) generated have very high kinetic energy and can seriously affect the safety of operators if they hit their bodies.

[0034] 2. During the drilling process, the operator steps down on the cover (specifically, a foot pedal is fixedly connected to the lower side wall of the cover for elastic lifting). The cover then elastically descends and covers the drilling location. During this process, the upper spring stretches and the lower spring compresses. In the early stages of drilling, the shape and size of the hole need to be determined. Therefore, the operator releases the foot pedal, and with the cooperation of the upper and lower springs, the cover elastically rises, making it easier for the operator to observe the drilling conditions. This method allows the operator to observe the hole condition during the drilling process.

[0035] 3. The outer shield further prevents flying stones, especially small gravel, from jumping out from the gap between the shield and the ore during the opening operation (because the ore has a non-planar structure, so there is often a gap between the shield and the ore after the shield is covered, especially for ore with severe irregularity). Therefore, the outer shield provides further protection. Attached Figure Description

[0047] Example 1

[0048] like Figure 1-7 As shown, a drilling protection device for static blasting areas in mountainous regions includes a drilling cover mechanism. During the drilling process, the drill rod of the drilling rig passes through the drilling cover mechanism and covers the drilling area. Even if flying rocks are generated, they impact the drilling cover mechanism, thus increasing the safety of the drilling operation. This is because the ore is hard, and the flying rocks generated by the high-speed rotating drill rod have very high kinetic energy, posing a great danger to the workers, especially to the head.

[0049] Specifically, the blasting drilling cover mechanism includes an inner splash guard structure 2 that covers the drilling location; specifically, the inner splash guard structure 2 includes a cover body 21, which is conical in shape (i.e., it includes a cylindrical portion that directly covers the drilling location, with the cylindrical portion integrally formed with the conical portion). An upper top plate 22 (the top of the conical portion) is fixedly connected to the top of the cover body 21, and a through hole is provided on the upper top plate 22; a drill rod (i.e., the drill rod of the drilling machine passes through the through hole, the size of which is much larger than the drill rod, so it does not affect the operation of the drill rod, while the depth of the blasting hole is often slightly larger, so the length of the drill rod is often also slightly longer) passes through the through hole.

[0050] Example 2

[0051] like Figure 1-7 As shown, in this embodiment, based on the structure of embodiment 1, the above-mentioned cover 21 structure is pre-aligned with the hole mark position during construction. Therefore, in order to adjust the cover 21 (the cover 21 is made of thin steel plate), the above also includes a frame structure set outside the inner splash guard structure 2; the inner splash guard structure 2 is slidably connected to the frame structure through a spring lifting structure.

[0052] The cover 21 can be adjusted horizontally by means of a spring lifting structure, so that the cover 21 can cover the opening position to the maximum extent, and the cover 21 can be flexibly raised and lowered during the opening process. The purpose is to make it easier to observe the state of the drilling (such as the shape of the hole) by raising the cover 21 during the opening process.

[0053] Specifically, the frame structure 1 includes an upper frame rod 11 and a lower frame rod 12 located below the upper frame rod 11; the upper frame rod 11 and the lower frame rod 12 are fixedly connected by four connecting rods 13 (the connecting rods 13 are located at the angle between the upper frame rod 11 and the lower frame rod 12). The frame structure 1 also serves as the skeleton of the entire device.

[0054] Meanwhile, a pair of mounting rods 23, spaced apart front to back, are fixedly connected to the side walls on the left and right sides of the top plate 22; the outer ends of the mounting rods 23 are slidably connected to spring lifting structures 24.

[0055] Specifically, the spring lifting structure 24 includes a spring sleeve rod, with an upper spring seat 242 and a lower spring seat fixedly connected to its top and bottom, respectively. Meanwhile, a sliding sleeve structure 231, slidably connected to the spring sleeve rod, is fixedly connected to the outer end of the mounting rod 23. Additionally, an upper spring 243 and a lower spring 244 are respectively sleeved on the upper and lower sides of the spring sleeve rod.

[0056] The upper spring 243 and the lower spring 244 are fixed in the following ways:

[0057] The two ends of the upper spring 243 are fixedly connected to the top of the upper spring seat 242 and the sliding sleeve structure 231, and the two ends of the lower spring 244 are fixedly connected to the bottom of the lower spring seat and the sliding sleeve structure 231, respectively.

[0058] The upper spring 243 and the lower spring 244 fix the sliding sleeve structure 231 in the following way:

[0059] The sliding sleeve structure 231 includes a sliding sleeve 2311 slidably connected to the spring sleeve rod. The top and bottom of the sliding sleeve 2311 are respectively welded with an upper annular flange and a lower annular flange 2312. The bottom of the upper spring 243 is fixedly connected to the upper annular flange, and the bottom of the lower spring 244 is fixedly connected to the lower annular flange 2312.

[0060] During operation, when the cover 21 is positioned over the drilling location, it is at a certain height (under the support of the drill rod structure described below, the cover 21 is normally in a raised position). The operator inserts the drill rod from the through hole on the top plate 22 into the cover 21 and places it against the ore drilling location. After confirming the drill rod is in the correct position, the operator lowers the cover 21 (specifically, a foot pedal 211 is fixedly connected to the lower end of the side wall of the cover 21 for elastic lifting). The cover 21 then elastically lowers and covers the drilling location. During this process, the upper spring 243 stretches and the lower spring 244 compresses. In the early stages of drilling, the shape and size of the hole need to be determined. Therefore, the operator releases the foot pedal, and with the cooperation of the upper and lower springs 244, the cover 21 elastically rises, facilitating the operator's observation of the drilling conditions.

[0061] Meanwhile, the operator can place their feet on the bottom of the pedal 211 to further raise the cover 21 (at this time, the upper spring 243 is compressed and the lower spring 244 is stretched), thereby further raising the cover 21 and making it easier to pass through.

[0062] Through the above-mentioned elastic lifting cover 21 design, the operation process can be coordinated with the hole shape observation during the hole opening operation. When observing the hole shape, the drilling machine stops, the operator releases his foot or lifts the pedal 211 (pushing the pedal 211 from the bottom), and the upper and lower springs 244 work together to raise and lower the cover 21.

[0063] With normal opening, pressing down with your foot keeps the cover 21 fully covering the opening area, thus effectively preventing gravel from flying everywhere and protecting the workers.

[0064] The top of the upper spring 243 seat 242 and the bottom of the lower spring 244 seat are respectively fixedly connected to sliding sleeves 241 that are slidably connected to the upper frame rod 11 and the lower frame rod 12. The position of the cover 21 is adjusted by sliding sleeves 241. The purpose is to ensure that the cover 21 completely covers the opening position by sliding the cover 21, rather than moving the entire device to precisely adjust the cover position, so as to achieve a more convenient and flexible adjustment of the cover 21's position.

[0065] Example 3

[0066] like Figure 1-7 As shown, in this embodiment, based on the structure of embodiment 2, in order to support the entire device on the ore during the drilling process, several drill rod structures 4 are installed on the lower frame rod 12.

[0067] The drill rod structure 4 includes a main drill rod 41 that is slidably connected to the lower frame rod 12 (the top of the main drill rod 41 is fixedly connected with an anti-detachment cap), and the lower side of the main drill rod 41 is threadedly connected with a height adjustment nut 411 that supports the bottom of the lower frame rod 12.

[0068] Because the ore has an uneven structure, the height of the main drill rods 41 on both sides needs to be adjusted during actual operation to ensure that the entire device is horizontally covered in the opening area.

[0069] The operation is as follows: The entire device is lifted and placed above the opening area, then the main drill rod 41 is freely lowered (the height adjustment nut 411 of the main drill rod 41 is adjusted to the lowest position). After all the main drill rods 41 are supported on the ore (at this time, the length of the main drill rods 41 extending beyond the lower frame rod 12 varies depending on the height of the ore), the height adjustment nut is supported at the bottom of the lower frame rod 12. At this point, the entire device is initially supported.

[0070] Meanwhile, the bottom of the main drill rod 41 is threadedly connected to an adjusting drill rod 42 (the bottom of the main drill rod 41 has a threaded groove of a certain depth); the bottom of the adjusting drill rod 42 is a conical tip (the rod body has a matching threaded structure); the adjusting drill rod 42 has an integrally formed hexagonal convex rib structure.

[0071] The operator uses a wrench to turn the adjusting rod 42 (a hexagonal convex structure) until the conical tip at the bottom of the adjusting rod 42 is properly driven into the ore (or the operator can directly use a hammer to strike the top of the main rod 41 to slightly anchor it). The adjusting rod 42 can also be adjusted in length extending from the main rod 41 through the above operation, thereby further adjusting the height of the entire device relative to the ore and adjusting the height of the cover 21 to ensure that the cover 21 can be positioned at the optimal distance from the opening (for easy observation of the hole condition during operation).

[0072] In actual operation, the entire device can be supported on the ore, because the device only serves to cover the opening area, so moderate anchoring is sufficient.

[0073] Example 4

[0074] like Figure 1-7 As shown, in this embodiment, based on the structure of embodiment 3, an outer shield 3 (shaped like a frame and also made of thin steel plate) is fitted on the outside of the inner splash shield structure 2; the outer shield 3 is fastened to the mounting rod 23 by several bolts 31; several weight-reducing holes are opened on the outer shield 3 (in order to reduce the overall weight).

[0075] In actual operation, in order to further prevent gravel from flying out of the weight reduction hole, a steel mesh can be welded into the weight reduction hole in the existing manner.

[0076] The outer cover 3 further prevents flying stones, especially small gravel, from jumping out from the gap between the cover 21 and the ore during the opening operation (because the ore has a non-planar structure, so after the cover 21 is covered, there is often still a gap between it and the ore, especially for ore with severe irregularity). Therefore, the outer cover 3 provides further protection.

[0077] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
