Description
Technical Field
[0001] This utility model relates to the field of coal mining technology, and in particular to a ore box for storing materials. Background Technology
[0002] In the underground coal mine working environment, standardized anti-impact quality is a crucial aspect of ensuring safe production. To achieve this goal, critical materials such as anti-impact drills, drill rods, binding wire, chain links, and pneumatic wrenches must be securely fixed to prevent displacement or damage under complex geological conditions. Currently, the industry commonly uses a method of securing materials in boxes, where the aforementioned equipment is systematically stored in dedicated mine boxes to improve management efficiency and operational safety.
[0003] To facilitate operators' visual inspection of the materials inside the container and their quick identification and retrieval of tools, most existing mine containers adopt an open-top design. This structure demonstrates significant advantages in improving operational convenience and visibility, especially in underground environments with insufficient light or limited space, where the open design greatly facilitates daily inspections and maintenance.
[0004] However, with increasing coal mining depth and more complex geological conditions, the underground working environment is becoming increasingly harsh. Traditional open-top coal boxes have revealed serious shortcomings in practical applications: due to the lack of effective top protection, loose coal, gangue, and other debris from the top or surrounding areas of the roadway can easily fall into the box, directly impacting materials and tools. For example, large chunks of coal falling may damage the drill pipe surface or break the anti-impact drilling rig, causing damage to equipment and materials and resulting in economic losses. Utility Model Content
[0005] The purpose of this utility model is to provide a ore box for storing materials. By covering the opening of the box with a protective net, it not only protects the box and prevents large coal blocks from falling into the box and damaging the materials or tools inside, but also facilitates observation of the material condition inside for quick identification and easy access to tools.
[0006] To achieve the above objectives, this utility model provides a ore box for storing materials, including a box body with an open top, and lifting lugs symmetrically arranged on the left and right sides of the box body; a protective net is provided over the open top of the box body, and the protective net covers the open top; a connecting structure is provided around the open top, and the protective net is detachably installed on the connecting structure; workers can observe the inside of the box body through the mesh of the protective net.
[0007] With the above structure, a protective net covering the opening prevents large chunks of coal falling from above from entering the container and damaging materials or tools inside. Smaller coal particles that do fall through the net are also less likely to cause significant damage due to their small weight, thus avoiding economic losses. The connecting structure allows for quick installation and removal of the protective net, facilitating easy opening and retrieval of tools. Workers can observe the interior of the container through the mesh of the net, enabling rapid monitoring and identification of the materials inside.
[0008] Preferably, the protective netting is a mesh panel structure; it includes a mesh frame and mesh panels disposed within the frame; a platform is provided on the four side walls of the opening above the enclosure, and the bottom of the mesh frame rests on the platform; the connecting structure includes positioning holes symmetrically arranged on the left and right sides of the mesh frame and corresponding fixing holes symmetrically arranged on the left and right side walls of the opening, with the positioning holes and corresponding fixing holes fixedly connected by pins. This structure increases the strength of the protective netting.
[0009] Preferably, two protective nets are installed side by side on the opening. This design reduces the weight of each net, facilitates opening, and allows for the opening of different nets as needed, thus reducing operational difficulty.
[0010] Preferably, the protective netting is a flexible structure; it includes two parallel guide rods arranged side-by-side, multiple sliding rods slidably installed between the two guide rods, and a flexible netting connecting adjacent sliding rods; the front and rear ends of the guide rods are fixed to the front and rear side walls of the opening, respectively, and the two guide rods are located on the left and right sides of the opening; each of the left and right ends of the sliding rods is provided with a sliding hook, which hooks onto the guide rod on its corresponding side; the flexible netting can achieve a certain degree of tension according to the sliding of the guide rods; the connecting structure includes hook assemblies provided on the front and rear side walls of the opening, with the sliding rods at the front and rear ends of the protective netting hooked onto the hook assemblies respectively. This structural design reduces the weight of the protective netting and also reduces the difficulty of opening it.
[0011] Preferably, the hook assembly includes a base fixed to the housing, an upper mounting seat and a lower baffle disposed on the base and arranged vertically opposite each other, with the upper mounting seat and the lower baffle forming a limiting groove into which the sliding rod can slide; a check plate is rotatably installed at the opening of the limiting groove. When the sliding rod slides into the limiting groove, the sliding rod can push the check plate to rotate, opening the groove to allow the sliding rod to enter. When the sliding rod returns to its original position, it is locked into the limiting groove. This structure prevents the protective net from accidentally detaching, thus avoiding protective failure.
[0012] Preferably, the upper mounting base is provided with a rotating shaft, and the check plate is rotatably mounted on the rotating shaft; the check plate includes a lower plate and an upper plate, and the rotating shaft is rotatably mounted between the lower plate and the upper plate; the lower plate extends downward into the limiting groove, and the back of the upper plate abuts against the upper mounting base; when the back of the upper plate abuts against the upper mounting base, the check plate is in a vertical state.
[0013] Preferably, the lower baffle has an arc-shaped guide surface at the opening of the limiting groove. This structure facilitates the smooth entry of the sliding rod into the limiting groove.
[0014] Preferably, a torsion spring is provided between the upper mounting base and the check plate, and the torsion spring causes the upper plate to abut against the upper mounting base. This structure assists in the reset of the check plate and prevents it from failing to automatically close the limit groove.
[0015] Preferably, traction ropes are provided on both the left and right sides of the flexible net, and slip rings are fixed to the traction ropes, with the slip rings slidably mounted on the guide rods. This structural design increases the strength of the flexible net.
[0016] Preferably, two hook assemblies are provided on each of the front and rear side walls of the opening. This structure can distribute the force on the slide rod and ensure its installation stability.
[0017] After adopting the above technical solution, the beneficial effects of this utility model are:
[0018] This utility model provides a material storage box that solves the technical problem in the prior art where open ore boxes cause debris to fall from above, damaging internal materials and tools and resulting in economic losses. This utility model provides a protective net over the opening of the box, which not only protects the box and prevents large coal blocks from falling into it and damaging the materials or tools inside, but also facilitates observation of the internal material condition for quick identification and easy access to tools.

[0026] The present invention will be further described below with reference to the accompanying drawings.
[0027] The orientations mentioned in this specification are based on the orientation of the ore box for storing materials under normal operation, and do not limit the orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.
[0028] Example 1:
[0029] A ore box for storing materials includes a box body 1 with an open top, and lifting lugs 11 symmetrically arranged on the left and right sides of the box body 1 to facilitate the lifting, handling and fixing of the ore box, thereby improving work efficiency. The number of lifting lugs 11 can be one or more pairs, and this embodiment does not limit this.
[0030] A protective net 2 covers the opening of the container 1. A connecting structure is provided around the perimeter of the opening, allowing the protective net 2 to be detachably installed on the connecting structure. This connecting structure enables quick installation and removal of the protective net 2, facilitating the opening of the container and easy access to tools. Workers can observe the interior of the container 1 through the mesh of the protective net 2. The mesh size of the protective net 2 is optimized to ensure clear observation of the materials inside the container while effectively preventing debris such as coal gangue from falling in.
[0031] Example 2:
[0032] One embodiment of protective netting 2, such as Figure 1 As shown, the protective net 2 is a mesh panel structure; it includes a mesh frame 21 and mesh panels 22 disposed within the mesh frame 21. It is made of metal and has high strength. Platforms are provided on the four side walls of the opening above the box 1, and the bottom of the mesh frame 21 rests on the platforms. Alternatively, recessed platforms can be provided around the opening of the box 1, with the mesh frame 21 secured within the recessed platforms.
[0033] The connection structure includes positioning holes 211 symmetrically arranged on the left and right sides of the mesh frame 21, and corresponding fixing holes symmetrically arranged on the left and right side walls of the opening. The positioning holes 211 and the corresponding fixing holes are fixed by pins. By temporarily fixing the mesh frame 21 to the opening with pins, the protective net 2 can be positioned and installed, so that it can stably cover the opening and not detach.
[0034] In practical applications, the lifting lug 11 can be shared with the fixing hole, such as... Figure 1 As shown, the two fixing holes and the two positioning holes 211 are fixedly connected by a connecting rod 23. During hoisting, the connecting rod 23 is used as a lifting rod, and the hook is hooked onto the connecting rod 23 for stable hooking. When disassembling the protective net 2, the connecting rod 23 is pulled out, and then the protective net 2 is lifted by hand to detach it from the opening, thus opening the opening.
[0035] Of course, independent fixing holes can also be used to fix the mesh frame 21. The position and size of the fixing holes are set according to the position and size of the positioning holes 211. They can be set symmetrically on the left and right side walls of the opening.
[0036] Because the ore box is relatively large, in order to reduce the weight of the protective net 2 while increasing its strength, two protective nets 2 can be installed side by side at the opening in this embodiment. The two protective nets 2 can be opened individually as needed.
[0037] Example 3:
[0038] In another embodiment, such as Figure 2-6 As shown, the protective net 2 is a flexible structure; it includes two parallel guide rods 24 arranged on the left and right, multiple sliding rods 25 slidably installed between the two guide rods 24, and a flexible net 26 connecting adjacent sliding rods 25.
[0039] The front and rear ends of the guide rod 24 are fixed to the front and rear side walls of the opening, respectively, and the two guide rods 24 are located on the left and right sides of the opening. This arrangement allows for the maximum working width of the opening and prevents the guide rods 24 from interfering with the placement of materials.
[0040] The slide rod 25 is provided with a sliding hook 251 at each of its left and right ends, and the sliding hook 251 is hooked onto the guide rod 24 on the corresponding side. By swinging the slide rod 25, the slide rod 25 can slide back and forth along the guide rod 24, and the flexible net 26 can be tensioned to a certain extent according to the sliding distance of the guide rod 24.
[0041] The flexible net 26 is made of flexible material. It can be a mesh structure composed of chain links or a mesh structure composed of ropes, as long as it can be unfolded and folded as the slide bar 25 slides.
[0042] The connecting structure includes hook assemblies 3 on the front and rear side walls of the opening, with sliding rods 25 at the front and rear ends of the protective net 2 hooked onto the hook assemblies 3 respectively. By hooking the sliding rods 25 on the front and rear sides of the opening, the protective net 2 is secured. When the opening needs to be opened, simply remove one side of the sliding rod 25 from the hook assembly 3, then push the sliding rod 25 to slide it to the other side to open the opening. This structure reduces the weight of the protective net 2 while facilitating the opening, improving convenience and work efficiency.
[0043] The hook assembly 3 can be a simple hook structure, but this embodiment provides an improved version of the hook assembly 3: the hook assembly 3 includes a base 31 fixed on the box 1, an upper mounting seat 32 and a lower baffle 33 disposed on the base 31 and arranged opposite each other, and the upper mounting seat 32 and the lower baffle 33 form a limiting groove into which the slide rod 25 can slide; a check plate 34 is rotatably installed at the opening of the limiting groove. In this embodiment, the check plate 34 is rotatably installed on the upper mounting seat 32. When the slide rod 25 slides into the limiting groove, the slide rod 25 can push the check plate 34 to rotate, opening the groove to allow the slide rod 25 to enter. When the check plate 34 returns to its original position, the slide rod 25 is locked in the limiting groove. Through this structure, the slide rod 25 is locked in one direction, preventing the protective net 2 from coming off the hook during transportation or vibration.
[0044] The installation method of check plate 34 is as follows:
[0045] A rotating shaft 321 is provided on the upper mounting base 32, and a check plate 34 is rotatably mounted on the rotating shaft 321. The check plate 34 includes a lower plate 341 and an upper plate 342, and the rotating shaft 321 is rotatably mounted between the lower plate 341 and the upper plate 342. The lower plate 341 extends downward into the limiting groove, and a limiting rod 322 is fixed on the side of the upper mounting base 32 away from the limiting groove, and the back of the upper plate 342 abuts against the limiting rod 322. When the back of the upper plate 342 abuts against the limiting rod 322, the check plate 34 is in a vertical state.
[0046] Furthermore, in order to facilitate the smooth entry of the slide bar 25 into the limiting groove, an arc-shaped guide surface 331 is provided on the lower baffle 33 at the opening of the limiting groove.
[0047] As an improvement, in order to assist the reset of the check plate 34 and prevent it from failing to automatically close the limit groove, a torsion spring 35 is provided between the upper mounting base 32 and the check plate 34. The torsion spring 35 drives the upper plate 342 to abut against the limit rod 322.
[0048] As another improvement, in order to increase the strength of the flexible net 26, traction ropes 261 are respectively provided on the left and right sides of the flexible net 26. Slip rings 262 are fixed on the traction ropes 261 and are slidably installed on the guide rods 24.
[0049] Two hook assemblies 3 are respectively installed on the front and rear side walls of the opening. The two hook assemblies 3 can distribute the force on the slide bar 25.
[0050] like Figure 2-6 As shown in Example 3, the workflow of a material storage box is as follows:
[0051] When the opening is closed, the sliding rods 25 on both sides of the protective net 2 are slid into the corresponding limiting grooves. The sliding rods 25 push the check plate 34 to rotate, and the grooves open to allow the sliding rods 25 to enter. When the sliding rods 25 are fully in, the check plate 34 resets under the action of gravity, and the sliding rods 25 are locked in the limiting grooves. When the protective net 2 is impacted from above or affected by other factors, the sliding rods 25 slide outward from the limiting grooves. Because the check plate 34 can only rotate in one direction, the sliding rods 25 cannot push the check plate 34 to rotate in the opposite direction, so the sliding rods 25 cannot come out of the limiting grooves.
[0052] When it is necessary to open the opening, push the lower plate 341 of the check plate 34 into the limiting groove to open the groove. At this time, the slide bar 25 can be removed from the groove.
[0053] 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.
