Description

Technical Field

[0001] This invention belongs to the field of coal mine conveying technology, and specifically relates to a continuous reversing device for coal mine electromechanical conveying. Background Technology

[0002] With the rapid development of economy and technology, electromechanical equipment plays an increasingly important role in coal mine safety production. In particular, coal mine electromechanical transportation equipment, as an important part of the mine production process, runs through all aspects of the mine production process and is found in every corner of the mine. It has the characteristics of wide scope, many special types of work, and high technical requirements. Moreover, the condition of coal mine electromechanical transportation equipment is directly related to coal mine safety production.

[0003] Currently, with the continuous development of coal mining technology, coal production efficiency is getting higher and higher. At the same time, it also puts forward higher requirements for coal mine electromechanical transportation equipment, such as requiring coal mine electromechanical transportation equipment to have the ability to change direction, so as to get rid of the problem that traditional coal mine electromechanical transportation equipment can only operate in one direction, so that coal can be transported by turning, thereby ensuring the continuity of the entire coal transportation path.

[0004] However, existing coal mine electromechanical transport equipment using continuous reversing devices often requires a shutdown operation during reversal, meaning that coal transport must be stopped during the reversal process to prevent coal from falling off. Therefore, existing coal mine electromechanical transport equipment cannot achieve continuous reversal, which undoubtedly increases coal transport time, reduces coal transport efficiency, and affects the progress of coal mining and coal processing. Furthermore, frequent shutdowns will inevitably increase equipment power consumption, which is inconsistent with the concept of energy conservation and environmental protection. Summary of the Invention

[0005] The purpose of this invention is to address the problem that existing coal mine electromechanical transportation equipment requires machine shutdown when reversing the direction of the transported materials. The invention proposes and designs a continuous reversing device for coal mine electromechanical transportation to overcome the above-mentioned problem and enable continuous reversing during coal transportation without stopping the machine.

[0006] To achieve the above objectives, the technical solution provided by the present invention is as follows: a continuous reversing device for coal mine electromechanical transportation, comprising an arc-shaped conveyor body, the arc-shaped conveyor body including a conveyor frame, a rotation drive mechanism being provided at the bottom of the conveyor frame, at least three conveying rollers being arranged circumferentially on the upper part of the conveyor frame, an arc-shaped conveyor belt being sleeved on the outer side of all the conveying rollers, and a conveyor motor being drivenly connected to the outermost conveying roller; a first coal conveyor, a second coal conveyor and a third coal conveyor being arranged circumferentially on the outer side of the conveyor frame, the output end of the first coal conveyor being located above the conveyor belt, the input ends of the second coal conveyor and the third coal conveyor being located below the conveyor belt, and a reversing guide plate and a door panel assembly being provided on the conveyor frame at positions corresponding to the input ends of the second coal conveyor and the third coal conveyor. Based on this, the present invention can continuously reverse the direction of coal by using the coordinated use of the arc-shaped conveyor, the reversing guide plate and the door panel assembly. The entire reversing process does not require machine stoppage, which can reduce the frequency of machine stoppage during coal transportation and improve coal transportation efficiency. Moreover, the reversing method of the present invention is simple, easy to operate, and saves time and effort.

[0007] Furthermore, the rotation drive mechanism includes a fixed base located below the conveyor frame. A rotating base and a servo motor are mounted on the bottom surface of the fixed base. A rotating shaft is rotatably mounted on the upper end of the rotating base. The upper end of the rotating shaft is fixedly connected to the conveyor frame. A large gear is fixedly mounted in the middle of the rotating shaft. The large gear meshes with a small gear. The small gear is fixedly mounted on the output shaft of the servo motor. The meshing between the small gear and the large gear drives the rotating shaft and the conveyor frame to rotate.

[0008] Furthermore, a turntable is fixedly installed on the upper part of the rotating shaft, and an annular conductor is fixedly installed at the upper end of the fixed frame. The annular conductor is sleeved on the outer ring of the turntable and provides radial support and constraint to the turntable to ensure the rotational stability of the rotating shaft.

[0009] Furthermore, the turntable's sidewall is evenly provided with at least two guide grooves along its circumference. The annular conductor includes an annular conductor shell, the outer ring of which is fixedly connected to a fixing frame. The inner ring of the conductor shell is evenly provided with at least two mounting grooves along its circumference, the number of which is the same as the number of guide grooves. Guide wheels are rotatably mounted in the mounting grooves, with one end of each guide wheel located in its corresponding guide groove. This makes the rotating shaft more stable during rotation, thereby improving the overall stability of the device.

[0010] Furthermore, slots are provided on the conveyor frame at positions corresponding to the input end of the second coal conveyor and the input end of the third coal conveyor. The two ends of the reversing guide plate are inserted into the corresponding slots, and in actual production, it can be selected whether to insert it into the corresponding position according to the actual production situation.

[0011] Furthermore, the guide plate is changed to an arc-shaped plate.

[0012] Furthermore, at least two guide rollers are rotatably installed at equal intervals on the side of the inner wall of the conveyor frame and / or the reversing guide plate that is in contact with the material. The guide rollers reduce the friction between the coal and the conveyor frame and the reversing guide plate of the arc-shaped conveyor body, thereby extending the service life of the arc-shaped conveyor body and the reversing guide plate.

[0013] Furthermore, the door panel assembly includes two symmetrically arranged arc-shaped door panels. The ends of the two arc-shaped door panels that are far apart from each other are hinged to the conveyor frame, while the ends of the two arc-shaped door panels that are close to each other are connected together by a door panel quick-connect mechanism. This design allows the door panel assembly to become part of the arc-shaped conveyor body, and it can guide and provide side protection for the coal during the conveying process when it is not open.

[0014] Furthermore, the quick-connect mechanism for the door panel includes sockets installed on two curved door panels, with a common plug rod inserted between the sockets on the two curved door panels, and the size of the plug rod being adapted to the size of the socket.

[0015] As can be seen from the above technical solutions, the present invention has the following advantages: 1. This invention enables continuous reversal of coal transport by using the coordinated use of an arc-shaped conveyor, a reversing guide plate, and a door panel assembly, without requiring machine downtime during the reversal process. This reduces the frequency of downtime during coal transport, improves coal transport efficiency, and the reversal method of this invention is simple, easy to operate, and saves time and effort. 2. By setting a rotation drive mechanism, the present invention can drive the arc-shaped conveyor body to rotate as a whole, so that the output port (the position of the door panel assembly) on the arc-shaped conveyor body can be adjusted according to the actual position of the coal conveyor. This makes the present invention highly flexible and easy to adjust, and can be adaptively adjusted according to the distribution of the conveyors on site. 3. By installing guide rollers on the inner walls of both sides of the arc-shaped conveyor and on the reversing guide plate, the present invention can guide the coal, reduce the friction between the coal and the conveyor frame of the arc-shaped conveyor and the reversing guide plate, and extend the service life of the arc-shaped conveyor and the reversing guide plate.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, the present invention provides a continuous reversing device for coal mine electromechanical transportation, which includes an arc-shaped conveyor body 1 and a first coal conveyor 2, a second coal conveyor 3 and a third coal conveyor 4 arranged circumferentially outside the arc-shaped conveyor body 1.

[0021] The arc-shaped conveyor 1 includes a conveyor frame 101, and a rotation drive mechanism 6 is provided at the bottom of the conveyor frame 101. The rotation drive mechanism 6 includes a fixed base located below the conveyor frame 101. A rotating base 605 and a servo motor 604 are mounted on the bottom surface of the fixed base. A rotating shaft 601 is rotatably mounted on the upper end of the rotating base 605. The upper end of the rotating shaft 601 is fixedly connected to the conveyor frame 101. A large gear 602 is fixedly mounted in the middle of the rotating shaft 601. The large gear 602 meshes with a small gear 603, and the small gear 603 is fixedly mounted on the output shaft of the servo motor 604. In this way, the meshing between the small gear 603 and the large gear 602 drives the rotating shaft 601 and the conveyor frame 101 to rotate, thereby adjusting the posture of the entire arc-shaped conveyor 1 so that its placement angle is adapted to the first coal conveyor 2, the second coal conveyor 3, and the third coal conveyor 4 located outside the arc-shaped conveyor 1.

[0022] Furthermore, as a preferred embodiment, the present invention can also fix a turntable 8 on the upper part of the rotating shaft 601, and fix an annular conductor 9 on the upper end of the fixing frame 7, and sleeve the annular conductor 9 on the outer ring of the turntable 8. In this way, the annular conductor 9 can provide radial support and constraint to the turntable 8, thereby ensuring the rotational stability of the rotating shaft 601. Specifically, as... Figure 3 As shown, the turntable 8 has at least two guide grooves 10 evenly arranged circumferentially on its sidewall. The annular conductor 9 includes an annular conductor shell 901, and the outer ring of the conductor shell 901 is fixedly connected to the fixing frame 7. The inner ring of the conductor shell 901 has at least two mounting grooves evenly arranged circumferentially, the number of which is the same as the number of guide grooves 10. Guide wheels 902 are rotatably mounted in the mounting grooves, with one end of each guide wheel 902 located in a corresponding guide groove 10. This cooperation between the guide wheels 902 and the guide grooves 10 makes the rotating shaft 601 more stable during rotation, thereby improving the overall stability of the device.

[0023] At least three conveyor rollers 102 are arranged circumferentially on the upper part of the conveyor frame 101. All the conveyor rollers 102 are covered by an arc-shaped conveyor belt 103. The output end of the first coal conveyor 2 is located above the conveyor belt 103, and the input ends of the second coal conveyor 3 and the third coal conveyor 4 are located below the conveyor belt 103. The outermost conveyor roller 102 is connected to a conveyor motor 104, which can drive the corresponding conveyor roller 102 to rotate, thereby realizing the rotation of the entire conveyor belt 103 (the working principle of the annular conveyor belt 103 is existing technology, such as the common turning conveyor on the market, so it will not be described in detail here).

[0024] Slots and door panel assemblies are provided on the conveyor frame 101 at positions corresponding to the input ends of the second coal conveyor 3 and the third coal conveyor 4. Arc-shaped reversing guide plates 5 can be detachably inserted into the conveyor frame 101 at these positions to achieve corresponding material blocking and guiding functions. Through the coordinated use of the arc-shaped conveyor body 1, the reversing guide plates 5, and the door panel assemblies, continuous reversing of coal transport can be achieved without stopping the machine during the entire reversing process. This reduces the frequency of machine stops during coal transport, improves coal transport efficiency, and the reversing method of this invention is simple, easy to operate, and saves time and effort.

[0025] Specifically, the door panel assembly includes two symmetrically arranged arc-shaped door panels 12. The ends of the two arc-shaped door panels 12 that are far apart are hinged to the conveyor frame 101 via hinges 13. The ends of the two arc-shaped door panels 12 that are close together are connected by a door panel quick-connect mechanism 14. The door panel quick-connect mechanism 14 includes sockets 1401 installed on the two arc-shaped door panels 12, and a common insertion rod 1402 is inserted between the sockets 1401 on the two arc-shaped door panels 12. This design allows the door panel assembly to become part of the arc-shaped conveyor body 1, and when not open, it can guide and provide side protection for the coal during the conveying process.

[0026] Furthermore, as a preferred embodiment, the present invention may also rotatably install at least two guide rollers 11 at equal intervals on the side of the reversing guide plate 5 that is in contact with the material and / or on the inner side wall of the conveyor frame 101, thereby reducing the friction between the coal and the conveyor frame 101 of the arc-shaped conveyor body 1 and the reversing guide plate 5, and extending the service life of the arc-shaped conveyor body 1 and the reversing guide plate 5.
