Description

Technical Field

[0001] The invention belongs to the technical field of mine material transportation, and in particular relates to a material container for rapid excavation and a material arrangement method. Background Art

[0002] Auxiliary transportation in coal mines mainly refers to the transportation of underground personnel, equipment, auxiliary materials and gangue, and is an indispensable and important part of the entire production system of the mine. Auxiliary transportation in coal mines can be divided into: endless rope winch, electric locomotive, trackless rubber-wheeled vehicle, monorail crane, etc. according to different transportation equipment.

[0003] In order to ensure that underground materials can be safely and efficiently delivered to the place of use, the transportation of equipment and auxiliary materials in auxiliary transportation is difficult, especially in mines that include multiple transportation systems such as electric locomotives, trackless rubber-wheeled vehicles, and monorail cranes. There is no unified material loading equipment, and the mine cars, material cars, and flatbed cars transported on the track cannot be directly transferred to rubber-wheeled vehicles or monorail cranes. The materials can only be manually transported to rubber-wheeled vehicles or monorail cranes, which greatly reduces the transportation efficiency and also poses safety hazards. The repeated loading and unloading of underground materials during the transfer of materials, no continuous transportation medium is generated between the various transportation systems, and they cannot form an integrated transportation system. There is no reliable loading device between the transportation systems, which makes the repeated labor of underground transportation equipment and auxiliary materials cause great waste of labor and reduce transportation efficiency.

[0004] Therefore, how to provide a mining material transport container that can operate as a whole between various transport systems and is suitable for various transport modes such as rail transport is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] Aiming at the problems of repeated loading and unloading of underground materials and low transportation efficiency, the present invention provides a material container for rapid excavation and a material arrangement method.

[0006] The present invention adopts the following technical solution:

[0007] A container for rapid excavation of materials comprises a box body with a rectangular cross-section, a box door is provided in the length direction of the box body, a baffle is provided in the width direction, the bottom of the box door is hinged to the box body by a hinge, brackets for connecting to a steel pipe of an extended belt rack are provided at the four corners of the bottom of the box body, and limit blocks are provided at the connecting ends of the box body and the box door. A door lock mechanism is provided on the container, and the door lock mechanism comprises a first steel pipe and a second steel pipe respectively located on the box body and the box door, and pins are inserted into the first steel pipe and the second steel pipe.

[0008] A method for arranging materials for rapid excavation comprises the following steps:

[0009] First step, according to the geological conditions of the coal mine and different mining and excavation processes, different support methods are adopted, and the materials for rapid tunneling are selected, including the types, quantities, weights, and models of the materials.

[0010] Second step, according to the selected materials for rapid tunneling, three-dimensional models of the materials are established in three-dimensional modeling software.

[0011] Third step, in the three-dimensional modeling software, the materials are arranged according to the transverse arrangement, longitudinal arrangement, and diagonal arrangement methods.

[0012] Furthermore, the transverse arrangement means that the length direction of the material is consistent with the length direction of the container; the longitudinal arrangement means that the length direction of the material is consistent with the width direction of the container; the diagonal arrangement means that the length direction of the material forms an angle with the length direction of the container.

[0013] Furthermore, when arranging the materials, the same type of support materials used are arranged in the same container, and the same type of materials are arranged in the same container.

[0014] Furthermore, when arranging the materials, different types of materials cannot be stacked on top of each other.

[0015] Furthermore, when arranging the materials, they are placed on one side of the container door.

[0016] Furthermore, when arranging the materials, the center of gravity of the container filled with materials should be located in the middle part of the container, and the height direction cannot exceed the height of the container.

[0017] The beneficial effects of the present invention are as follows:

[0018] By using the material arrangement method of the present invention, the overall operation between each transportation system is achieved.

[0019] The container of the present invention is suitable for the transportation of mining materials in various transportation modes such as track transportation.

[0020] By using the device and method of the present invention, the labor waste caused by repeated labor during the transportation of underground transportation equipment and auxiliary materials is reduced, the repeated loading and unloading of materials is avoided, and the transfer efficiency of underground materials is improved.

Specific implementation manners

[0028] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0029] A material container for rapid tunneling and a material layout method. The material container for rapid tunneling includes a box body, a box door and a door lock mechanism. The box body and the box door are connected by hinges, and the hinges are welded to the box body and the box door respectively. The material layout method is that the customer custom - selects the materials for rapid tunneling, including the type, quantity, weight and model of the materials. The software arranges the materials on the container in an orderly manner according to a certain sequence, realizing time - saving and labor - saving material loading and unloading.

[0030] After on - site investigation, the materials for rapid tunneling include materials for roof support, rib support and materials for extending the belt conveyor frame. Among them, the roof support adopts the combined support of "threaded steel bolt + W - shaped steel belt + cable bolt + steel bar mesh", and the materials used include threaded steel bolts, W - shaped steel belts, cable bolts, steel bar meshes, resin CK, threaded steel bolt trays, cable bolt trays; the rib support includes positive rib support and secondary rib support. The positive rib support adopts the combined support of "fiberglass bolt + plastic mesh", and the materials used include fiberglass bolts, plastic meshes, trays, resin CK; the secondary rib support adopts the combined support of "round steel bolt + cold drawn wire mesh", and the materials used include quick bolts (including round steel bolts, trays and locks), cold drawn wire meshes; the materials for extending the belt conveyor frame include H - shaped steel frames, upper idlers, lower idlers, steel pipes.

[0031] The box body is welded by angle steel, channel steel and steel strip. The channel steel is welded at the bottom of the box body, and the container can be placed on the steel pipe of the extended belt rack.

[0032] The box door takes the hinge as the rotation axis and can rotate outward by 90°. A limit block is arranged on the side of the box body to limit the larger rotation angle of the door. The door lock mechanism consists of a pin shaft, steel pipe Ⅰ and steel pipe Ⅱ. Steel pipe Ⅰ and steel pipe Ⅱ are welded to the box body and the box door of the material container for rapid tunneling respectively. When the pin shaft passes through steel pipe Ⅰ and steel pipe Ⅱ respectively, the box door is in the closed state; when the pin shaft is taken out, the box door can rotate.

[0033] Furthermore, according to the daily footage of 40m, the quantities of materials required for roof support, side support and extended belt rack are determined as shown in the following table. At the same time, according to the size specifications and weights of the materials, they are arranged on the material container for rapid tunneling, which improves the space occupancy rate of the container and the efficiency of material loading and unloading.

[0034]

[0035] Furthermore, the present invention also provides a method for arranging materials for rapid tunneling. The arrangement method includes the following steps:

[0036] Step 1, the customer customizes and selects the materials for rapid use, including the types, quantities, weights and models of the materials. Different geological conditions and different mining and excavation processes in coal mines adopt different support methods, and different support methods lead to different types, quantities and models of support materials.

[0037] Step 2, reconstruct the 3D model of the materials. According to the support method selected by the customer, determine the types, quantities, weights and models of the materials for rapid tunneling, and establish the 3D model of the materials in 3D modeling software.

[0038] Step 3, arrange the materials in the software according to the established horizontal, vertical and diagonal arrangement methods to achieve time-saving and labor-saving material loading and unloading. The horizontal arrangement means that the length direction of the material is consistent with the length direction of the container; the vertical arrangement means that the length direction of the material is consistent with the width direction of the container; the diagonal arrangement means that the length direction of the material forms an angle with the length direction of the container. For the convenience of taking materials at the working face, the material arrangement requirements include:

[0039] Requirement (1): As much as possible, the materials used for the same support method are arranged in the same container, and the same type of materials are arranged on the same container as much as possible;

[0040] Requirement (2): When arranging materials, it is required that different types of materials cannot be overlapped;

[0041] Requirement (3): The materials are arranged on the door side of the container as much as possible for easy direct taking;

[0042] Requirement (4): The center of gravity of the container filled with materials should be located in the middle part of the container, and the height should not exceed the height of the container in the height direction.
