Description

Technical Field

[0001] This utility model relates to the field of material anchoring technology, and in particular to a comprehensive material rack for tunneling faces. Background Technology

[0002] In underground coal mine tunneling faces, support operations are crucial for ensuring roadway stability and preventing roof collapse. Commonly used support materials include rock bolts, anchor cables, rock bolt discs, large support trays, and anchor cable discs. The storage and management of these materials directly affect support efficiency and operational safety. However, current methods of storing support materials in tunneling faces generally suffer from the following problems: 1. Materials are mixed together, making retrieval inconvenient and affecting operational efficiency; 2. Rock bolts, trays, etc., are prone to rolling and slipping, posing safety hazards; 3. Lack of classified storage easily leads to material damage or loss.

[0003] To achieve standardized management, simple supports or welded racks are commonly used in underground mines. However, these supports or welded racks have limited functions and can only store a single type of material (such as only anchor bolts or only pallets), which cannot meet the needs of comprehensive support. Utility Model Content

[0004] The purpose of this utility model is to provide a comprehensive material rack for tunneling faces. By dividing the material rack into sections and setting different positions in each section, a variety of materials can be stored, thus meeting the needs of comprehensive support.

[0005] To achieve the above objectives, this utility model provides a comprehensive material rack for a tunneling face, comprising a base extending front to back, the base being divided into two parts from left to right; the left part is divided into an anchor bolt storage area; the right part is sequentially divided into an anchor bolt disc storage area, a large pallet storage area, and an anchor cable disc storage area; the anchor bolt storage area has two rows of limiting posts arranged opposite each other in the left and right directions, the two rows of limiting posts forming a front-to-back through placement channel; the anchor bolts are stacked laterally in the placement channel, with their front and rear ends protruding from the base respectively; the anchor bolt disc storage area is used to place anchor bolt discs, and the anchor cable disc storage area is used to place anchor cable discs; the anchor bolt disc storage area and the anchor cable disc storage area are each provided with a screw post whose bottom is fixed to the base and extends upward; the center holes of the anchor bolt discs and anchor cable discs are respectively fitted onto the screw posts in their corresponding areas; the large pallet storage area is used to place large pallets; it is provided with an upward-facing box, the size of which is set according to the size of the large pallet.

[0006] By adopting the above structure, the material rack is divided into sections, and different placement methods are set according to the structure of different materials. For example, anchor bolts, which are longer, can be stacked horizontally, while anchor bolt discs and anchor cable discs, which have central holes, can be inserted using the central hole insertion method; large pallets, which do not have central holes, are stored in the form of boxes. This achieves the storage of various materials. Different positioning is set in each area. For example, a placement channel is set in the anchor bolt storage area to prevent anchor bolts from scattering; bolt posts are set in the anchor bolt disc and anchor cable disc storage areas to prevent anchor bolt discs and anchor cable discs from scattering; and boxes are set in the large pallet storage area to prevent large pallets from scattering. This meets the comprehensive support requirements.

[0007] Preferably, each storage area is equipped with a rooting device. The rooting device in the anchor bolt storage area includes anti-detachment columns arranged in a left-right direction and detachably installed on the limiting columns on the left and right sides of the placement channel. Multiple anti-detachment columns are arranged along the extension direction of the placement channel, and the multiple anti-detachment columns press against the top anchor bolt. The rooting devices in the anchor bolt disc storage area and the anchor cable disc storage area have the same structure, including a locking nut screwed onto the screw column, which abuts against the top anchor bolt disc or anchor cable disc. The rooting device in the large pallet storage area includes through holes arranged opposite each other on both sides of the box opening. The lowest point of the through hole is equal to the height of the large pallet, and a through rod or circular chain is fitted inside the through hole. The through rod or circular chain abuts against the top of the large pallet. By setting up the rooting device, the material rack can avoid scattering due to vibration or conveying inertia during the conveying process, thus improving the rooting stability of the material.

[0008] Preferably, the right side of the base also includes a consumables area; the consumables area has a consumables box with an open top; the left rear of the left side of the base also includes a safety auxiliary tool area; the safety auxiliary tool area has a shelf with its bottom fixed to the base and its top extending upwards, and the shelf has fixing holes for fixing different safety auxiliary tools. This structure improves the functionality of the material rack.

[0009] Preferably, multiple sets of support rods can be detachably installed at both ends of the placement channel, located at the bottom of the anti-detachment column. The left and right ends of the support rods are fixedly installed on the limiting columns. Each layer of anchor rods corresponds to one set of support rods. The support rods support the anchor rods of that layer. The upper support rods press against the lower anchor rods. With this structure, a fixed number of anchor rods are installed on each layer of support rods, so during inventory checks, only the number of layers needs to be counted. By placing the anchor rods on the support rods, the weight is distributed to the support rods, thereby reducing the pressure on the bottom anchor rods and preventing deformation. Furthermore, the upper support rods pressing against the lower anchor rods achieve a top-pressing effect, thus fixing the upper position of the anchor rods and ensuring their anchoring effect. In this embodiment, the topmost anti-detachment column can be replaced by a support rod.

[0010] Preferably, multiple limiting grooves are evenly arranged on the circumferential surface of the support rod along its axial direction. The limiting grooves are annular grooves arranged around the support rod, which allow the anchor rod to be engaged. The anchor rod is clamped between the limiting grooves of the upper and lower support rods. This structure can prevent the anchor rods in this layer from swaying left and right.

[0011] Preferably, each limiting post has multiple rows of support rods arranged side-by-side, with the rows of support rods staggered vertically to support anchor rods at different levels. This structure increases the spacing between adjacent support rods, preventing damage to the limiting post's strength.

[0012] Preferably, the limiting post is provided with a limiting hole for inserting a support rod. The limiting hole on the left side of the limiting channel is a blind hole, while the mounting hole on the right side of the limiting channel is a through hole. The support rod is inserted from one side of the through hole, and its inner side abuts against the blind hole; its outer side protrudes through the through hole. This structure allows for the rapid insertion and removal of the limiting post.

[0013] Preferably, a stop bar is slidably mounted on the limiting post, and the stop bar can slide to the outside of the through hole and close the through hole; a locking bolt is provided between the stop bar and the limiting post, and the locking bolt fixes the position of the stop bar. This structure can prevent the limiting post from coming out.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] This utility model, a comprehensive material rack for tunneling faces, solves the technical problem that existing material racks for tunneling faces have limited functionality and cannot meet the needs of comprehensive support. This utility model divides the material rack into sections and sets different locations in each section, thereby enabling the storage of various materials and meeting the needs of comprehensive support.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] The orientations mentioned in this specification are based on the orientation of the integrated material rack for tunneling faces under normal operation, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.

[0026] Example 1:

[0027] like Figure 1 and Figure 2 As shown in the figure, a comprehensive material rack for a tunneling face includes a base 1 extending forward and backward. Support legs 11 are fixed at the four corners of the bottom of the base 1. Rooting plates are provided at the bottom of the support legs 11, and rooting holes are provided on the rooting plates for rooting and fixing the base 1.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the base 1 is divided into two parts from left to right; the left part C1 is divided into anchor bolt storage area 2; the right part C2 is divided into anchor bolt plate storage area 3, large tray storage area 4 and anchor cable plate storage area 5 in sequence.

[0029] Two rows of limiting posts 21 are arranged opposite each other in the left and right directions of the anchor storage area 2, forming a through placement channel. In this embodiment, each row of limiting posts 21 has two posts, located at the front and rear ends of the placement channel, and the four limiting posts 21 form a cuboid placement space. The anchor rods 20 are stacked horizontally in the placement channel, with their front and rear ends protruding from the base 1. Because the anchor rods 20 are generally quite long, if only one side protrudes from the base 1, it is easy for the support to be unstable, causing it to tip over from one side. Therefore, by having both ends protrude from the base 1, the overall center of gravity is located above the base 1, preventing it from tipping over.

[0030] Anchor bolt disc storage area 3 is used to place anchor bolt discs 30, while anchor cable disc storage area 5 is used to place anchor cable discs 50. Both anchor bolt discs 30 and anchor cable discs 50 have a central hole, so their positioning methods are the same. The following detailed explanation will only take anchor bolt disc storage area 3 as an example.

[0031] An anchor bolt storage area 3 is provided with a screw post 31 that is fixed at the bottom to the base 1 and extends upward; the center hole of the anchor bolt 30 is fitted onto the screw post 31 in the corresponding area; thus realizing the stacking of the anchor bolt 30.

[0032] The large pallet storage area 4 is used to place large pallets 40. The large pallet storage area 4 is equipped with an upward-facing box 41, the size of which is determined according to the size of the large pallet 40. The large pallet 40 is inserted sideways into the box 41, thus realizing the placement of the large pallet 40 (e.g., ...). Figure 2 (As shown). The specific placement direction and method can be adjusted according to the actual situation. It can be inserted sideways or stacked. This embodiment does not limit this.

[0033] This device allows for different placement methods for different materials based on their structure. For example, the anchor rod 20, which is relatively long, can be stacked horizontally, while the anchor rod disc 30 and the anchor cable disc 50 both have a central hole and can be inserted into each other using the central hole. The large tray 40, however, does not have a central hole, so it is stored in the form of a box 41.

[0034] In another embodiment, to enhance the functionality of the material rack, a consumables area 8 is provided on the right side C2 of the base 1. The consumables area 8 has a consumables box 81 with an open top. The consumables box 81 can be used to store consumables such as anchoring agents and drill bits, which can be fixed inside the consumables box 81 by cable ties or other means. To facilitate this fixing, corresponding fixing positions can be provided inside the consumables box 81 for anchoring and fixing consumables such as anchoring agents and drill bits. A safety auxiliary tool area 7 is also provided on the left rear of the left side C1 of the base 1. The safety auxiliary tool area 7 has a placement rack 71 with its bottom fixed to the base 1 and its top extending upwards. The placement rack 71 has fixing holes 711. The fixing holes 711 are used to fix different safety auxiliary tools, such as hydraulic supports, which can be fixed inside the fixing holes 711 by wire or cable ties for anchoring. Of course, the consumables area 8 and the safety auxiliary tool area 7 can be selectively provided according to actual conditions, or they can be omitted.

[0035] Example 2:

[0036] To improve the stability of materials stored in each area and prevent them from scattering due to vibration or conveying inertia, this embodiment is a further improvement on embodiment one, with a rooting device installed in each storage area.

[0037] The anchoring device in the anchor storage area 2 includes anti-detachment columns 62 arranged in a left-right direction and detachably installed on the limiting columns 21 on the left and right sides of the placement channel. Multiple anti-detachment columns 62 are arranged side-by-side along the extension direction of the placement channel, pressing against the topmost anchor 20 and pressing the stacked anchors 20 tightly onto the base 1. This increases the friction between the anchors 20, preventing slippage due to collisions or vibrations, thus preventing the anchors 20 from scattering. The anti-detachment columns 62 effectively anchor the anchors 20. In this embodiment, because there are two sets of limiting columns 21, there are two anti-detachment columns 62, located at the front and rear ends of the placement channel, respectively.

[0038] The detachable installation method of the anti-detachment post 62 is as follows: Limiting holes 61 are made opposite to each other on the limiting posts 21 on both sides of the placement channel, and the anti-detachment post 62 is inserted into the limiting holes 61. By setting U-shaped pins or locking nuts at one end of the anti-detachment post 62 that protrudes from the limiting holes 61, the anti-detachment post 62 is fixed within the limiting holes 61, thus preventing it from coming out of the limiting holes 61.

[0039] The height of the limiting hole 61 can be set according to the number of anchor rods 20 layers, ensuring that when the anti-detachment post 62 is inserted into the limiting hole 61, the bottom of the anti-detachment post 62 abuts against the side wall of the uppermost anchor rod 20. Of course, each limiting post 21 can have one or more limiting holes 61. Multiple limiting holes 61 can limit the anchor rods 20 in different layers.

[0040] The anchor bolt storage area 3 and the anchor cable storage area 5 have the same anchoring device structure; including a locking nut 311 screwed onto the bolt post 31, the locking nut 311 abutting against the topmost anchor bolt 30 or anchor cable 50; thereby locking the anchor bolt 30 or anchor cable 50 onto the base 1, thus achieving anchoring and fixing of the two.

[0041] The rooting device in the large tray storage area 4 includes through holes 411 positioned opposite each other on both sides of the opening of the box 41. The through holes 411 are circular, and the height of their lowest point is equal to the height of the large tray 40. A through rod or circular chain is fitted inside the through holes 411. The box 41 is pressed against the top of the large tray 40 by the through rod or circular chain, thereby locking the large tray 40 onto the base 1 and achieving rooting and fixation of the large tray 40.

[0042] By setting up a rooting device, the material rack can be prevented from scattering due to vibration or conveying inertia during the transportation process, thus improving the rooting stability of the material.

[0043] Example 3:

[0044] This embodiment further improves the anchor storage area 2 based on embodiment 2. In embodiment 2, the anchors 20 are stacked on top of each other, and the bottom anchor 20 is subjected to greater pressure and is prone to deformation. In addition, because the anchor 20 is not a completely circular structure, and a nut is provided at one end, the interference of the nut means that each layer of anchors 20 will not be completely seamlessly tightened. This results in gaps between the anchors 20. If misalignment occurs when stacking, it will not only be inconvenient to count, but also easily cause anchor failure.

[0045] This embodiment improves upon the rooting device in Embodiment 2. Its specific structure is as follows: Multiple sets of support rods 63 can be detachably installed at the front and rear ends of the placement channel, located at the bottom of the anti-detachment column 62. The left and right ends of the support rods 63 are respectively fixedly installed on the limiting column 21; one layer of anchor rods 20 corresponds to one set of support rods 63; the support rods 63 support the anchor rods 20 of that layer; the upper layer of support rods 63 presses against the lower layer of anchor rods 20. With this structure, a fixed number of anchor rods 20 are installed on each layer of support rods 63, so only the number of layers needs to be counted during inventory. By placing the anchor rods 20 on the support rods 63, the weight can be distributed to the support rods 63, thereby reducing the pressure on the bottom anchor rods 20 and preventing deformation; in addition, by pressing the upper layer of support rods 63 against the lower layer of anchor rods 20, a top clamping effect is achieved, thus fixing the upper position of the anchor rods 20 and ensuring the rooting effect of the anchor rods 20. In this embodiment, the topmost anti-detachment column 62 can be replaced by support rods 63.

[0046] The support rod 63 is installed as follows: the number of limiting holes 61 on each limiting post 21 is set according to the number of layers where the anchor rods 20 are placed. One support rod 63 is inserted into each set of limiting holes 61.

[0047] like Figure 5 and Figure 6 As shown, to prevent each anchor rod 20 from swaying left and right on the support rod 63, multiple limiting grooves 631 are evenly provided along the axial direction on the circumferential surface of the support rod 63 in this embodiment. The limiting grooves 631 are annular grooves arranged around the support rod 63, which allow the anchor rod 20 to be inserted. The anchor rod 20 is clamped between the limiting grooves 631 of the upper and lower support rods 63.

[0048] As an improvement, because the diameter of the anchor rod 20 is small, the upper and lower limiting holes 61 are too dense, which seriously affects the strength of the limiting post 21.

[0049] To solve the above problems, multiple rows of limiting holes 61 can be arranged side by side on each limiting post 21. In this embodiment, two rows of limiting holes 61 are provided, and the two rows of limiting holes 61 are staggered vertically, corresponding to anchor rods 20 in different layers. By setting this structure, the distance between adjacent limiting holes 61 in the same row can be increased, thus preventing damage to the strength of the limiting post 21.

[0050] As an improvement, since there are multiple support rods 63, using U-pins or locking nuts for anti-loosening would be labor-intensive. Therefore, this embodiment improves efficiency. The limiting hole 61 on the left side of the limiting channel is a blind hole; while the mounting hole on the right side of the limiting channel is a through hole. The support rod 63 is inserted from the through hole side, and its inner side abuts against the blind hole; its outer side protrudes through the through hole.

[0051] like Figure 7 As shown, a stop bar 212 is slidably mounted on the limiting post 21. Its specific structure is as follows: a sliding post 211 extending in the front-to-back direction is fixed to the top and bottom of the limiting post 21, respectively. A sliding sleeve is slidably mounted on the sliding post 211, and the upper and lower ends of the stop bar 212 are fixed to the sliding sleeve. The stop bar 212 can slide to the outside of the through hole and close the through hole.

[0052] A locking bolt 213 is provided between the stop bar 212 and the sliding column 211 to fix the position of the stop bar 212. After all the support rods 63 are installed, the stop bar 212 is slid to the outside of the limiting hole 61 to close the through hole, thereby preventing the support rods 63 from coming out. Then, the locking bolt 213 is tightened to fix the position of the stop bar 212. This structure allows for the simultaneous closure of a row of limiting holes 61, improving work efficiency.

[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.
