[0021] In the prior art known to the inventors of the present application, most of the existing sidewall mining equipment adopts a solution of a mining machine towing multiple sections of quick-joined belt conveyors during long-distance loading and transportation. This solution has the following problems: 1. The solution of a continuous mining machine towing multiple sections of quick-joined belt conveyors has low space utilization, weak ability to escape from emergencies such as landslides, and huge costs for escape; 2. The use of the continuous mining machine's walking device as the power for mining propulsion limits the mining depth and construction efficiency of the equipment; 3. The use of multiple sections of quick-joined belt conveyors for transportation results in extremely high labor costs and transportation costs, and further increases the difficulty of escaping equipment in distress; 4. If any of the belt conveyors slips, deviates, or has other problems, the transportation system will stop, increasing the risk and cost of personnel maintenance.

[0022] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Example 1

[0023] Combination Figure 1The present invention provides a long-distance loading and transportation system for sidewall mining equipment, including a system body, wherein the system body includes a cutting mechanism for sidewall mining, and the system body also includes a loading mechanism 1, a transportation mechanism 2 and a propulsion mechanism. The loading mechanism 1 is used to receive the slag cut by the cutting mechanism, and a loading unit is provided in the loading mechanism 1; the transportation mechanism 2 is connected to the tail of the loading mechanism 1, and the tail of the loading mechanism 1 and the transportation mechanism 2 form a continuous transportation channel, and a transportation unit is provided in the transportation channel; the propulsion mechanism includes a plurality of propulsion units 3 connected in sequence, and each propulsion unit 3 is provided with a double helix mechanism 31, the frontmost propulsion unit 3 is connected to the tail of the transportation mechanism 2, and the tail of the rearmost propulsion unit 3 is connected to a power mechanism. In a specific embodiment, the power mechanism includes an oil cylinder so that the system body has a stable mining propulsion force.

[0024] When the power mechanism drives the system body to advance, the slag cut by the cutting mechanism enters the loading mechanism 1, and the loading unit loads the slag to the tail of the loading mechanism 1. Then the transportation unit transports the slag along the transportation channel to the frontmost propulsion unit 3, and the double screw mechanism 31 in each propulsion unit 3 pushes the slag from the frontmost propulsion unit 3 to the rearmost propulsion unit 3.

[0025] Combination Figure 2-Figure 3 As for the loading mechanism 1, in a specific embodiment, the loading unit of the loading mechanism 1 includes a star wheel mechanism 12, and the star wheel mechanism 12 is arranged on both sides of the starting end of the transportation channel.

[0026] In another specific embodiment, in combination Figure 2 and Figure 4 , side thrust mechanisms 11 are provided on both sides of the loading mechanism 1, and the side thrust mechanisms 11 include side thrust plates 111 and side thrust cylinders 112; one end of the side thrust plates 111 is hinged to the side of the loading mechanism 1, and the other end is connected to the telescopic end of the side thrust cylinder 112; when the side thrust cylinder 112 is fully extended, the width between the side thrust plates 111 on both sides of the loading mechanism 1 is consistent with the cutting width of the cutting mechanism.

[0027] In conjunction with the use process, the system posture during propulsion can be corrected in time by opening and closing the side thrust mechanism 11. The side thrust plate 111, which is the main working component, is a V-shaped side thrust plate 111 with a large obtuse angle. When the side thrust cylinder 112 is fully extended, the side thrust mechanism 11 is fully opened, and the overlapping width of the loading mechanism 1 and the side thrust mechanism 11 is consistent with the cutting mechanism width of the sidewall mining equipment, thereby ensuring the correctness and stability of the system posture.

[0028] As for the transport mechanism 2, in a specific embodiment, in combination with Figure 5 The transport mechanism 2 includes a frame 21, the transport channel is located in the frame 21, and the transport unit includes a transporter 22. A sliding shoe structure 211 that is inclined and bent upward is arranged at the front end of the frame 21. The sliding shoe structure 211 is used to disperse the load and reduce friction.

[0029] In another specific embodiment, a gantry structure 212 is provided above the transport channel, and the gantry structure 212 is used to limit the size of the slag entering the front end of the propulsion unit 3 along the transport channel. In conjunction with the use process, since the chamber is required to be unmanned during sidewall mining, it is necessary to avoid as much as possible the transportation system of the equipment from getting stuck and other failures during long-distance transportation. Therefore, a gantry structure 212 is provided above the transport channel in this embodiment as a slag size screening device, which can prevent slag beyond the specified volume from entering the transportation system and minimize the risk of getting stuck. In addition, this system is used for sidewall mining, the slag is soft in texture, and there are few large pieces of slag. The filtering device plays an insurance role, and the transport channel itself has a certain slope. The slag blocked by the gantry structure 212 will naturally fall to the front end of the system body and will not affect the normal operation of the system.

[0030] Combination Figure 6 As for the propulsion mechanism, in a specific embodiment, the propulsion unit 3 can be in various shapes, and is optimized as a rectangular parallelepiped in the present invention. The double helix mechanism 31 is mirror-imaged in the propulsion unit 3 to ensure that the slag can be transported to the outside with the rotation of the helix. When the propulsion unit 3 transports the slag, the top cover 33 above it can close the transportation system for protection.

[0031] In another specific embodiment, both ends of the propulsion unit 3 are provided with a flexible connection mechanism 32, and adjacent propulsion units 3 are connected by the flexible connection mechanism 32, and the frontmost propulsion unit 3 is also connected to the frame 21 of the transport mechanism 2 by the flexible connection mechanism 32, and the rear of the frame 21 of the transport mechanism 2 is reserved with an installation position for connecting with the flexible connection mechanism 32. The flexible connection mechanism 32 allows adjacent propulsion units 3 to rise and fall within a preset angle range.

[0032] In a specific embodiment, in combination Figure 6 and Figure 7, the flexible connection mechanism 32 includes a tongue plate 322 and a pin-shaft pin-hole assembly 321; the head and / or tail of each propulsion unit 3 is provided with a tongue plate 322, and the tongue plate 322 is located at the positions on both sides of the double-screw mechanism 31; the head of the rear propulsion unit 3 and the tail of the front propulsion unit 3 can be connected through the tongue plate 322 and the limit pin 324 to limit the freedom of the propulsion unit 3 to swing in the horizontal direction. Usually, a protruding tongue plate 322 is provided on one side of the head and the tail, and a groove for the tongue plate 322 to extend into is formed on the other side. After the protruding tongue plate 322 extends into the groove, the limit pin 324 is inserted vertically to achieve connection.

[0033] In a specific embodiment, in combination Figure 5 The tongue plate 322 on the right side of the head of the propulsion unit 3 protrudes, and a groove is formed on the right side of the tail; the tongue plate 322 on the left side of the tail of the propulsion unit 3 protrudes, and a groove is formed on the left side of the tail; the adjacent propulsion units 3 can be stably connected by cooperating with the limit pins through the tongue plate between the head and the tail.

[0034] In a specific embodiment, limit blocks 323 are provided on both sides of the tongue plate 322 to limit the tongue plate 322 between the side frame of the propulsion unit 3 and the double screw mechanism 31 .

[0035] In addition, the pin shaft and pin hole assembly 321 includes a first pin shaft and a first pin hole that cooperate with each other, and a second pin shaft and a second pin hole that cooperate with each other; the first pin shaft and the first pin hole are respectively arranged at the tail and head of the spiral shaft of the double spiral mechanism 31; the second pin shaft and the second pin hole are respectively arranged at the tail and head of the side frame of the propulsion mechanism.

[0036] Combination Figure 7 and Figure 8 The inner walls of the first pin hole and the second pin hole are formed with a taper angle that expands from the middle to both ends; the taper angle allows adjacent propulsion units 3 to retain vertical freedom, so that the multi-section propulsion units 3 can adapt to the undulating terrain after being connected. Usually, the taper in the first pin hole and the second pin hole is small. In a specific embodiment, the taper is 3°.

[0037] In addition, the ends of the first pin shaft and the second pin shaft are both formed with cone heads, which mainly play the role of guiding and correcting deviation, so that the hole axes of the two propulsion units can be quickly aligned.

[0038] In this embodiment, the above structure can ensure that after several sections of propulsion units 3 are docked, the system has sufficient freedom to adapt to the undulating terrain. In a specific embodiment, the undulating angle between adjacent propulsion units 3 corresponding to the taper is 3°. It can be understood that the degree of freedom of the flexible connection is limited, and the undulating angle is designed to be ±3°, so that multiple sections can be superimposed at different angles to adapt to the terrain over long distances, and the entire system can be propulsed close to the ground over short distances. In addition, it should be supplemented that the bottom of the propulsion unit 3 is made of high-strength and wear-resistant material, and the propulsion unit 3 can be disassembled for inspection and maintenance after a working cycle, and the friction has little effect on the function of the system. In addition, the double helix mechanism 31 of the multi-section propulsion unit 3 is driven to rotate by the same driving mechanism to maintain the same rotation speed. Example 2

[0039] The difference between this embodiment and embodiment 1 is that, further, for the construction of the sidewall mining equipment underground or in the cavern, the geological conditions are complex, and all the pipes, lines and devices of a series of indoor mechanisms such as the equipment front-end cutting mechanism, loading mechanism 1, transportation mechanism 2, and propulsion unit 3 are easily affected by the external environment. If the pipes and lines are worn, scratched, etc., it may cause production safety accidents and even the risk of system paralysis. Therefore, in the long-distance loading and transportation working system involved in the present invention, each mechanism has a closed space to close and protect the normal use of the pipes and lines in harsh environments.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
