Description

Technical Field

[0001] This invention belongs to the field of trackless auxiliary transportation technology in coal mines, specifically relating to a complete set of equipment and methods for containerized trackless transportation of production materials in tunneling faces. Background Technology

[0002] The supply and distribution of coal mine production materials is a crucial link in the coal mine production system, and its operational efficiency and technological level have a significant impact on the high-yield and high-efficiency development of coal mines. With the rapid development of mining technology and equipment, trackless auxiliary transportation technology and equipment face the demands of higher transportation efficiency, fewer personnel at the working face, and a higher level of informatization. Production materials at coal mine tunneling faces include support materials, construction materials, ventilation and drainage pipes, electromechanical parts, etc., which are diverse in type and unique in shape. The rapid and intelligent development of rapid tunneling technology and equipment has increased the demand for production materials several times over.

[0003] Currently, the transportation of production materials at the tunneling face uses a fragmented loading and unloading mode with various vehicle types, which presents the following problems: 1. The processes are dispersed and complex, requiring a large number of vehicles and personnel. Pipeline transport vehicles, bulk material transport vehicles, and other types of vehicles are dedicated to specific purposes, resulting in a large number of vehicles, long waiting times, backlogs, and low vehicle turnover and transport efficiency. 2. Auxiliary transport at the working face is intermittent, leading to low transfer efficiency. The underground unloading point is located 300-400m from the tunneling face face. Due to the narrow space of the roadway side of the tunneling equipment (only 1.2-1.4m), existing trackless vehicles have difficulty passing through, relying mainly on manual transport. This requires a large number of workers, is labor-intensive, and has low transport efficiency. Furthermore, the delivery of tunneling and anchoring equipment parts is difficult, affecting equipment maintenance. 3. Unloading is difficult underground, leading to material accumulation. Currently, most trackless vehicles cannot be loaded and unloaded quickly as a whole. Underground unloading, sorting, and stacking rely on manual labor, which is labor-intensive, time-consuming, and results in poor safety and unfavorable underground site management due to material accumulation.

[0004] The fragmented material supply model and the imbalance between tunneling production have hindered efficient coal mine production and intelligent construction, becoming a weak link in the safe and efficient mining of modern mines. To meet the requirements of reduced manpower and efficient material transportation in tunneling faces, the continuous and intensive development of auxiliary transportation systems has become an important direction. Therefore, it is necessary to reform the existing fragmented auxiliary transportation model in tunneling faces and study new trackless transportation methods and supporting auxiliary transportation equipment. Summary of the Invention

[0005] To address the problems of multiple material transportation links, low equipment technology level, large number of personnel and vehicles, and high labor intensity in tunneling faces, this invention provides a complete set of trackless equipment and methods for containerized transportation of production materials in tunneling faces. This allows for the modularization of production material storage units and their integrated transportation and rapid transfer, achieving point-to-point mechanized and efficient transportation of production materials from the surface storage center to the underground tunneling face. This realizes the continuity, intensification, and efficiency of the trackless auxiliary transportation system, ultimately reducing manpower and improving efficiency in underground working face auxiliary transportation.

[0006] The technical solution adopted in this invention is a complete set of trackless containerized transportation equipment for production materials in tunneling faces, including a container transport vehicle, containers, and a tunneling material transport train set. The container transport vehicle is equipped with a transport platform and a container self-loading and unloading mechanism. The transport platform and containers can be quickly connected or separated. The tunneling material transport train set consists of a narrow tunneling material transport vehicle pulling several tunneling material flatbed cars. The container transport vehicle runs back and forth between the surface and underground, and the tunneling material transport train set shuttles along one side of the underground tunneling equipment. The two types of equipment are connected underground to transfer containerized materials.

[0007] Furthermore, the container self-loading and unloading mechanism is a side-discharge type, including a lifting mechanism and a support mechanism symmetrically arranged above the front and rear sides of the transport platform. When the container needs to be unloaded, the lifting mechanism lifts the container and moves it horizontally to the side of the vehicle to the ground or a designated height position at the unloading point. When the container needs to be loaded, the lifting mechanism lifts the container from the side of the vehicle and moves it horizontally back to the container transport vehicle's transport platform. The support mechanism includes outriggers, which support the ground on the loading and unloading side of the container during the loading and unloading operation of the lifting mechanism.

[0008] Furthermore, the lifting mechanism includes a support arm hinged to the lifting side of the transport platform, a boom hinged to the free end of the support arm, a lifting section provided on the inner side of the free end of the boom, the lifting section being connected to a chain and a hook to connect to a container, the cylinder end of a first hydraulic cylinder hinged to the side of the transport platform away from the lifting side, the strut end of the first hydraulic cylinder hinged to the support arm, the cylinder end of a second hydraulic cylinder hinged to the lifting side of the transport platform, and the strut end of the second hydraulic cylinder hinged to the boom.

[0009] Furthermore, the support mechanism includes outriggers hinged to the hoisting side of the transport platform, a cylinder end of a third hydraulic cylinder hinged to the transport platform away from the hoisting side, and a strut end of the third hydraulic cylinder hinged to the outriggers.

[0010] Furthermore, the transport platform is equipped with four sets of container limiting mechanisms and locking mechanisms for quick fixation and locking of containers after loading. The container limiting mechanism is Y-shaped, which allows the container to quickly fall into the frame formed by the four container limiting mechanisms after loading. The locking mechanism is a pin type, which can quickly lock the container.

[0011] Furthermore, the container transport vehicle uses an oil-gas suspension system, which allows for height adjustment based on the roadway height.

[0012] Furthermore, depending on the type of materials being packed, containers can be fitted with internal partitions to form various different types of containers.

[0013] Furthermore, the narrow-body material transport vehicle adopts a tracked walking mode, can be remotely or manually controlled, and adopts a two-way driving operation mode.

[0014] Furthermore, the tunneling material flatbed truck uses rubber wheels for travel and is equipped with a tire lateral swing mechanism. Container fixing devices are installed on the flatbed of the tunneling material flatbed truck.

[0015] Compared with the prior art, the beneficial effects of the complete set of equipment for containerized trackless transportation of production materials at the tunneling face of the present invention are as follows:

[0016] 1) This invention relates to a complete set of containerized trackless transport equipment for production materials at the tunneling face. The containers can be quickly connected or separated from container transport vehicles. After being lowered into the mine, they can be unloaded as a whole at the unloading point onto the tunneling material transport train, which then transports them to the tunneling face. The combined use and rapid docking of the containerized transport equipment enables point-to-point mechanized continuous transport of materials.

[0017] 2) The container transport vehicle of the present invention adopts a side loading and unloading method for containers, which is convenient for mechanized loading and unloading, and the containers are kept horizontal during unloading, resulting in high freight quality; it adopts an oil and gas suspension system, the vehicle height is adjustable, and it has strong adaptability to alleyways.

[0018] 3) The tunneling material transport train of this invention consists of a narrow-type tunneling material transport car pulling several tunneling material flatbed cars to travel in narrow tunnels and follow the tunneling equipment to deliver materials, which can realize trackless transportation at deep tunneling depths; it has a strong carrying capacity and can be used as a mobile warehouse, making material retrieval convenient; the narrow-type tunneling material transport car adopts a two-way driving mode, running back and forth in narrow tunnels, which is highly maneuverable and adaptable; the narrow-type tunneling material transport car and the tunneling material flatbed cars can be quickly connected or separated, making loading and unloading flexible and the vehicle utilization rate high.

Simultaneously, it allows for tracking and control of containerized materials, improving material flow and supply-demand management. This method enables the continuous, intensive, and efficient operation of the trackless auxiliary transportation system. Attached Figure Description

Detailed Implementation

[0044] To better understand the purpose, structure, and function of this invention, the following detailed description, in conjunction with the accompanying drawings, provides a complete set of trackless equipment and methods for containerized transport of production materials at the tunneling face.

[0045] like Figure 1 As shown, a set of trackless transport equipment for containerized production materials in a tunneling face includes a container transport vehicle 1, a container 2, and a tunneling material transport train set 3. The tunneling material transport train set 3 is composed of a narrow tunneling material transport vehicle 3-1 pulling several tunneling material flatbed cars 3-2.

[0046] In the complete set of trackless containerized transportation equipment for production materials at the tunneling face, the container transport vehicle 1 runs back and forth between the surface and underground. The container transport vehicle 1 is equipped with a transport platform 1-2 and a container self-loading and unloading mechanism 1-1. The transport platform 1-2 and the container 2 can be quickly connected or separated, enabling rapid loading, unloading, and transfer of the container 2. The tunneling material transport train set 3 shuttles along one side of the underground tunneling equipment. The container transport vehicle 1 and the tunneling material transport train set 3 connect underground to transfer containerized materials.

[0047] The material transport process is as follows: Container transport vehicle 1 travels to the underground unloading point, and tunneling material transport train 3 reverses to the side of container transport vehicle 1. Container transport vehicle 1 then transfers container 2 to tunneling material transport train 3, which continues to deliver the material to the working face, or container transport vehicle 1 transfers container 2 to the belt conveyor 4-1 of the tunneling equipment 4 above the belt rack 4-2. The material recovery process is the reverse of the transport process. Tunneling material transport train 3 delivers the material to be recovered to the underground unloading point, or container 2 remains placed above the belt rack 4-2, and container transport vehicle 1 transfers container 2 to itself.

[0048] like Figure 2 and Figure 3 As shown, the container transport vehicle 1 includes a container self-loading and unloading mechanism 1-1, a transport platform 1-2, tires 1-3, a drive axle 1-4, a frame 1-5, and an oil-gas suspension 1-6. The transport platform 1-2 is located above and behind the frame 1-5, the container self-loading and unloading mechanism 1-1 is located at both ends above the transport platform 1-2, and the oil-gas suspension 1-6 is located below and behind the frame 1-5.

[0049] The container self-loading and unloading mechanism 1-1 is a side-discharge type, including a lifting mechanism 1-1-1 and a support mechanism 1-1-2. The lifting mechanism 1-1-1 includes a support arm hinged to the lifting side of the transport platform 1-2. The free end of the support arm is hinged to the boom. A lifting section is provided on the inner side of the free end of the boom. The lifting section is connected to a chain and a hook to connect to the container 2. The cylinder end of the first hydraulic cylinder is hinged to the side of the transport platform 1-2 away from the lifting side. The strut end of the first hydraulic cylinder is hinged to the support arm. The cylinder end of the second hydraulic cylinder is hinged to the side of the transport platform 1-2 on the lifting side. The strut end of the second hydraulic cylinder is hinged to the boom. The support mechanism 1-1-2 includes a support leg hinged to the lifting side of the transport platform 1-2. The cylinder end of the third hydraulic cylinder is hinged to the side of the transport platform 1-2 away from the lifting side. The strut end of the third hydraulic cylinder is hinged to the support leg. When container 2 needs to be unloaded, the crane mechanism 1-1-1 lifts container 2 and moves it horizontally to one side of the vehicle body to the ground or a designated height position at the unloading point. When container 2 needs to be loaded, the crane mechanism 1-1-1 lifts container 2 from one side of the vehicle body and moves it horizontally back to the container transport vehicle 1's carrying platform 1-2. Container 2 remains level during loading and unloading. The outriggers of the support mechanism 1-1-2 are equipped with balance valves to prevent the outriggers from buckling or sinking on their own.

[0050] The transport platform 1-2 is equipped with four sets of container limiting mechanisms 1-2-1 and locking mechanisms 1-2-2. After container 2 is loaded, it can be quickly secured and locked to prevent movement and detachment during transportation. The container limiting mechanism 1-2-1 is a Y-shaped guide type, allowing the container to quickly fall into the frame formed by the four limiting mechanisms 1-2-1 after loading. The locking mechanism 1-2-2 is a pin type, which can quickly lock the container to prevent movement and detachment during transportation. The container limiting mechanism 1-2-1 and locking mechanism 1-2-2 can be operated manually or hydraulically.

[0051] The container transport vehicle 1 uses an oil-gas suspension 1-6, which adjusts the vehicle height according to the height of the aisle. In low aisles, the vehicle is lowered to reduce the loading and unloading height of the container 2, and in higher aisles, the vehicle is raised to improve the driver's visibility.

[0052] like Figure 4As shown, container 2 meets the diverse and complex material storage needs of tunneling production. Its design features rational partitioning for categorized material storage, and employs detachable partitions and layered design for easy material handling. Container 2 is divided into four types based on the type of material it contains: container 2-1, container 2-2, container 2-3, and container 2-4. Container 2-1 has internal transverse partitions and is suitable for long wire mesh sheets and anchor cables. Container 2-2 has internal longitudinal and transverse partitions and is suitable for loose materials such as anchor bolts, plastic wire mesh rolls, anchoring agents, and pallets. Container 2-3 has internal longitudinal partitions and is suitable for brick bundles. Container 2-4 has no internal partitions and is suitable for bulk materials.

[0053] like Figure 5 As shown, the tunneling material transport train set 3 consists of a tunneling material narrow-type transport car 3-1 pulling several tunneling material flatbed cars 3-2. The tunneling material narrow-type transport car 3-1 and the tunneling material flatbed cars 3-2 adopt a traction connection mechanism that can be quickly disassembled and assembled.

[0054] The narrow-type tunneling material transport vehicle 3-1 includes a track assembly 3-1-1, a frame 3-1-2, a cab 3-1-3, and a traction mechanism 3-1-4. The track assembly 3-1-1 is located below the frame 3-1-2, the cab 3-1-3 is located on the upper left side of the frame 3-1-2, and the traction mechanism 3-1-4 is located at the rear of the frame 3-1-2, or at the front of each tunneling material flatbed 3-2. The narrow-type tunneling material transport vehicle 3-1 uses a tracked walking method, adaptable to uneven working face conditions, steep slopes, gravel roads, and muddy roads. The narrow-type tunneling material transport vehicle 3-1 employs both high-speed and low-speed travel speed control. High speed is used in areas with ample space to improve transport efficiency, while low speed is used in narrow areas to facilitate adjustment of the vehicle's posture and passage through tunnels. The narrow-type tunneling material transport vehicle 3-1 uses a two-way driving control method, allowing it to reciprocate within narrow passages on one side of the tunneling equipment without needing to turn around. The tunneling material narrow-type transport vehicle 3-1 uses remote control for all actions such as starting, walking, turning, horn, lights, and stopping, while retaining manual control. The manual and remote control are interlocked.

[0055] The tunneling material flatbed 3-2 includes a flatbed 3-2-1, rubber-tired wheels 3-2-2, and a tire lateral swaying mechanism 3-2-3. The flatbed 3-2-1 is equipped with a container securing device, which can accommodate four sets of container limiting mechanisms 1-2-1 and locking mechanisms 1-2-2, identical to those on the loading platform 1-2. The tunneling material flatbed 3-2 travels on rubber-tired wheels 3-2-2 and features a tire lateral swaying mechanism 3-2-3, improving its maneuverability.

[0056] like Figure 6As shown, a method for containerized trackless transportation of production materials at a tunneling face, employing a complete set of containerized trackless transportation equipment, includes the following steps:

[0057] Step 1, Loading above ground: Based on the type and quantity of materials required for underground production, the storage center uses container 2 for loading and preparing goods, and calls upon container transport vehicle 1.

[0058] Step 2, Surface-to-underground transport: Container transport vehicle 1 quickly connects to container 2 on the surface and then transports it to the underground unloading point.

[0059] The third step is underground connection and transfer.

[0060] Step 4: Delivery at the tunnel face.

[0061] Based on the conditions of the tunnel, the following three schemes can be adopted for underground transfer and delivery and delivery at the tunnel face.

[0062] like Figure 7 As shown, the first scheme for underground transfer and delivery at the tunneling face is as follows: The tunneling material transport train set 3 consists of a narrow-type tunneling material transport car 3-1 pulling several tunneling material flatbed cars 3-2. With the tunneling direction as a reference, the narrow-type tunneling material transport car 3-1 can be positioned at the front or rear of the tunneling material transport train set 3. When transporting materials following the tunneling equipment 4, the narrow-type tunneling material transport car 3-1 is positioned at the front of the tunneling material transport train set 3, pulling the train set forward. When it is necessary to return to the unloading point to reconnect materials, the narrow-type tunneling material transport car 3-1 separates from the tunneling material flatbed cars 3-2, moves out of the queue, and then travels backward to the rear of the tunneling material transport train set 3. It then connects with the tunneling material flatbed cars 3-2, pulling the train set 3 backward from the rear.

[0063] like Figure 8As shown, the second scheme for underground transfer and face-of-drilling material delivery is as follows: the tunneling material transport train set 3 consists of two narrow-type tunneling material transport cars 3-1 and several tunneling material flatbed cars 3-2. One narrow-type tunneling material transport car 3-1 is located at the front and one at the rear of the tunneling material transport train set 3, while the several tunneling material flatbed cars 3-2 are located in the middle of the tunneling material transport train set 3. This scheme is provided because some tunneling roadways are narrow, making it impossible to place two pieces of equipment side-by-side, and the narrow-type tunneling material transport cars 3-1 cannot be moved out of the queue. In this scheme, when transporting materials with the tunneling equipment 4, the front tunneling material narrow transport vehicle 3-1 pulls the tunneling material transport train 3 forward, while the rear tunneling material narrow transport vehicle 3-1 releases its brakes and follows the convoy, or detaches from the tunneling material flatbed vehicle 3-2 and remains in place; when it is necessary to return to the unloading point to pick up materials, the rear tunneling material narrow transport vehicle 3-1 pulls the tunneling material transport train 3 backward, while the front tunneling material narrow transport vehicle 3-1 releases its brakes and follows the convoy backward, or detaches from the tunneling material flatbed vehicle 3-2 and remains in place.

[0064] like Figure 9 and Figure 10 As shown, the third scheme for underground transfer and tunneling face delivery is applicable to narrow tunneling faces where there is no need for a tunneling material transport train set 3. In this scheme, the container transport vehicle 1 unloads the container 2 as a whole at the underground unloading point and places it on the material rack 4-2 of the belt conveyor 4-1. The material rack 4-2 moves automatically with the tunneling equipment 4. The material in the container 2 is retrieved as needed. After use, the container transport vehicle 1 loads the empty container 2 and transports it to the surface.

[0065] The composition and operation mode of the tunneling material transport train set 3 of the present invention are not limited to the three schemes provided in the embodiments. Those skilled in the art can also adjust the position of the tunneling material narrow transport car 3-1 in the tunneling material transport train set 3 according to the tunnel conditions and transportation requirements.

[0066] Step 5, Material Recovery: The tunneling material transport train 3 delivers damaged materials, substandard materials, and electromechanical parts, etc. Empty container 2 and container transport vehicle 1 are called up. The container transport vehicle 1 quickly connects to container 2 underground and then transports it to the surface storage center, where the recycled materials are processed.

[0067] Following the steps above, from step one to step five, and then from step five back to step one, a containerized transportation cycle of production materials from the tunneling face, from loading onto trucks at the surface to material recovery, is completed, and production material distribution information forms a closed loop.

[0068] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present invention.
