[0002] In the process of coal mining, especially underground coal mining, a large number of support mechanisms are usually required to assist in preventing mine cave collapse. As the excavation section of the coal mine excavation working face becomes larger and the support strength increases, the types and quantities of materials and equipment used are increasing, and material and equipment management has become a management pain point. The use of traditional methods is not only time-consuming and labor-intensive, but also prone to material loss and waste, and a decline in the standardized management of safety and quality of the overall tunnel. Therefore, in the actual management of support equipment materials, it is necessary to improve the material management device. The current various materials have the following disadvantages in the turnover of actual excavation operations:

[0003] 1. In the process of supporting coal mine tunnels, various types of channel steel, protective nets, anchor cables, steel bars, connectors and other structures are included. In the past, these materials were heavy and bulky. As the excavation working face extended, it was difficult to move them forward. If they were piled up in large quantities, it would be even more inconvenient to transport them. Therefore, relevant material racks are needed to classify them and help with their use;

[0004] 2. As for the small materials often used in the head-on support of the excavation working face, such as anchors, spherical pads, pallets, locks and other small materials, this type of material generally has the characteristics of small size, irregular shape, and difficult unloading in the original traditional mine car. Therefore, the turnover transportation of such small materials also needs to be improved. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a movable material rack device, comprising a bottom frame, a turnover basket, a vertical rod, a support plate and a top plate, the centers of the upper end surfaces of the two short arms of the bottom frame are fixed with vertical rods, the centers of the two side surfaces of the vertical rods are fixed with support plates, and a threaded barrel is fixed on the top surface of the support plate away from one end of the vertical rod, and the inner thread of the threaded barrel is connected to a screw rod; the top of the vertical rod is fixed with a top plate, the top surfaces of the two ends of the top plate are fixed with threaded barrels, and the inner thread of the threaded barrel is connected to a screw rod.

[0008] Furthermore, reinforcing rods are fixed between the two inner end surfaces of the bottom frame and symmetrically distributed turnover baskets are placed on the reinforcing rods. The highest point of the reinforcing rods is lower than the height of the upper end surface of the bottom frame.

[0009] Furthermore, the bottom surfaces of the two long arms of the bottom frame are rotatably connected with symmetrically distributed walking wheels, the two end surfaces of the bottom frame are fixed with symmetrically distributed threaded tubes, and the inner threads of the threaded tubes are connected with connecting screws, and a handle is fixed in the middle of the connecting screws.

[0010] Furthermore, symmetrically distributed reinforcing cross beams are welded and fixed between the two vertical rods, and the turnover baskets are distributed on both sides of the reinforcing cross beams.

[0011] Furthermore, the sum of the lengths of the two support plates is greater than the length of the top plate.

[0012] Furthermore, the height of the turnover basket is lower than the height of the support plate.

[0013] Furthermore, the cross-sections of the bottom frame and the vertical rods are both I-shaped.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model solves the problem that it is inconvenient to classify and store coal mine support materials in the mine cave and to carry out turnover transportation by arranging a bottom frame, vertical bars, support plates and top plates; the device can be used in combination and can be adapted to the classified storage and use of materials such as channel steels and steel bars of various lengths.

They are used for placing small materials, and the baskets on the same side of the vertical bars Anchor cables, channel steels and other long materials can be placed on the support plate and the top plate, and the device is placed under the monorail crane track in the tunnel. As the excavation working face extends, the device can be lifted forward by a monorail crane, which greatly reduces the workload of the transportation personnel, realizes classified storage, and is convenient for turnover transportation. If the material is long, the device can be assembled and used, and the connecting screw can be connected to the threaded pipe at one end of the two bottom frames to connect the two bottom frames, so that multiple devices can be used in combination.

[0016] 2.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] See also Figure 1-7As shown, the utility model is a movable material rack device, including a bottom frame 1, a turnover basket 2, a vertical rod 3, a support plate 4 and a top plate 5. The vertical rods 3 are fixed at the centers of the upper end surfaces of the two short arms of the bottom frame 1, and the support plates 4 are fixed at the centers of the two side surfaces of the vertical rods 3. A threaded cylinder 401 is fixed on the top surface of the support plate 4 away from one end of the vertical rod 3, and a screw 402 is connected to the inner thread of the threaded cylinder 401; the top plate 5 is fixed to the top of the vertical rod 3, and the top surfaces of the two ends of the top plate 5 are fixed with threaded cylinders 501, and the screws 502 are connected to the inner thread of the threaded cylinder 501;

[0029] The bottom frame 1 is a rectangular frame structure, which is welded from I-beams. Two vertical rods 3 are fixed on the bottom frame 1. Support plates 4 are arranged on the sides of the vertical rods 3 for placing supporting materials. At the same time, a top plate 5 is fixed on the top of the vertical rods 3. When more than two top plates 5 are used at the same time, they can support materials with a long length. Multiple devices can be assembled and used synchronously.

[0030] When supporting materials (channel steel, steel cable, steel bar, etc.) are placed on the support plate 4, they can be blocked by the threaded barrel 401 and the screw rod 402 to prevent them from sliding off from the end of the support plate 4 after being placed. The screw rod 402 rotates in the threaded barrel 401 to achieve lifting and lowering, and can be adapted to be used for blocking at different heights; similarly, the setting of the threaded barrel 501 and the screw rod 502 on the end of the top plate 5 can also block the materials placed on the top plate 5 to prevent them from sliding off from the end of the top plate 5. At the same time, the screw rod 502 can rotate and rise and fall in the threaded barrel to achieve blocking at different heights.

[0031] Between the two inner end faces of the bottom frame 1, there are fixed equidistantly distributed reinforcing rods 104, and symmetrically distributed turnover baskets 2 are placed on the reinforcing rods 104, and the highest point of the reinforcing rods 104 is lower than the height of the upper end face of the bottom frame 1;

[0032] The reinforcing rod 104 is used to strengthen the structural strength of the bottom frame 1, and at the same time, it is convenient to place the turnover basket 2 for use. Because the highest point of the reinforcing rod 104 is lower than the upper end surface height of the bottom frame 1, the turnover basket 2 will not slide off the bottom frame 1. The turnover basket 2 is used to place small materials frequently used in support, such as anchors, spherical pads, pallets, locks and other small materials.

[0033] The bottom surfaces of the two long arms of the bottom frame 1 are both rotatably connected with symmetrically distributed walking wheels 101, and both end surfaces of the bottom frame 1 are fixed with symmetrically distributed threaded tubes 102, and the threaded tubes 102 are internally threadedly connected with connecting screws 103, and the middle of the connecting screws 103 is fixed with a handle 1031;

[0034] The bottom frame 1 can be moved a short distance by the walking wheels 101, which is convenient for moving during assembly and reduces the labor intensity of manual handling; the threaded tube 102 is a square tube with a threaded groove inside for screwing into the connecting screw 103, and the connecting screw 103 can be used to connect the threaded tubes 102 at one end of the two bottom frames 1. The connecting screws 103 are respectively screwed into the threaded tubes 102 at one end of the two bottom frames 1 to achieve the connection and assembly between the two devices.

[0035] A symmetrically distributed reinforcing beam 301 is welded and fixed between the two vertical rods 3, and the turnover basket 2 is distributed on both sides of the reinforcing beam 301; the structural strength is improved by the reinforcing beam 301 between the two vertical rods 3, and the turnover basket 2 is distributed on both sides of the reinforcing beam 301 to reduce direct hard collision.

[0036] The sum of the lengths of the two support plates 4 is greater than the length of the top plate 5 ; when placing materials on the support plates 4 , the influence of the top plate 5 is reduced.

[0037] The height of the turnover basket 2 is lower than the height of the support plate 4 ; the materials placed on the support plate 4 will not affect the turnover basket 2 .

[0038] The cross sections of the bottom frame 1 and the vertical rod 3 are both I-shaped; both are formed by welding I-beams.

[0039] The specific working principle of the utility model is as follows: first, the bottom frame 1 is a rectangular frame structure, two vertical rods 3 are fixed on the bottom frame 1, and support plates 4 are arranged on the sides of the vertical rods 3. The support plates 4 on the same side of the vertical plates are used to place support materials. At the same time, a top plate 5 is also fixed on the top of the vertical rods 3. When more than two top plates 5 are used at the same time, they can be used to support materials with a long length. When supporting materials (channel steel, steel cables, steel bars, etc.) are placed on the support plates 4, they can be blocked by the threaded tube 401 and the screw rod 402 to prevent them from sliding off the ends of the support plates 4 after being placed; similarly, the top plate 5 on the ends of the top plates The arrangement of the threaded barrel 2 501 and the screw 2 502 can also block the materials placed on the top plate 5 to prevent them from sliding off the end of the top plate 5. The turnover basket 2 is used to place small pieces of materials frequently used in support. When loading on the ground at one time, various types of materials are classified and loaded in each turnover basket 2, and are placed on the reinforcing rod 104 after being lowered into the well. The bottom frame 1 can be moved a short distance by the walking wheel 101, which is convenient for mobile use during assembly. The connecting screw 103 is respectively screwed into the threaded tube 102 at one end of the two bottom frames 1 to realize the connection and assembly between the two devices (such as Figure 7 As shown in the figure, the device is placed under the monorail crane track in the tunnel. As the excavation working face extends, the device can be lifted and moved forward by a monorail crane.
