Description

Technical Field

[0001] The utility model relates to the technical field of underground mining machinery and equipment, and specifically relates to a continuous conveying type material propelling vehicle. Background Technique

[0002] With the continuous development of the coal mining industry, the mechanization level of coal mining has been significantly improved in recent years. However, in the key areas of coal mine safety production, such as the prevention and control of rock bursts and mine tremors, the modernization level of technical equipment is still relatively lagging. In particular, when dealing with the thick and hard roof above the coal seam, the technical problems of implementing advanced deep-hole blasting construction are particularly prominent, and there is still a lack of special equipment designed specifically for such operations in the current market.

[0003] In the existing coal mining face, when performing deep-hole blasting operations on the roof, it mainly relies on the manual operation mode. In this process, the charging link is particularly onerous, not only requiring multiple people to cooperate, but also occupying a large amount of human resources, directly resulting in a significant increase in the labor intensity of workers, while the overall construction efficiency is difficult to improve. More seriously, due to almost all the operation processes relying on manual operation, its safety issues cannot be ignored, and there are relatively high safety risks.

[0004] Although in the explosive pushing link, some machinery and equipment have been involved to assist in reducing the manual burden, these devices are often complex in actual operation and difficult to fully achieve automation and high efficiency. In addition, the current research on explosive auxiliary pushing devices mostly focuses on non-continuous pushing technologies. This method is not only inefficient, but also still requires frequent manual intervention, and fails to fundamentally solve the problems of waste of human resources and low operation efficiency. To sum up, there are obvious shortcomings in the technical equipment and operation efficiency of the advanced deep-hole blasting construction for the thick and hard roof in coal mining, and there is an urgent need to develop a high-efficiency, safe and automated special equipment to meet the actual production needs.

[0020] A continuous conveying type material propulsion vehicle according to the present utility model, as Figures 1 - 5 shown, includes a crawler vehicle 1. The crawler vehicle 1 functions to travel in a roadway, and at the same time, the crawler vehicle 1 also serves as an installation foundation for a support mechanism and a conveying mechanism. A slide plate 2 capable of longitudinal movement is installed on the crawler vehicle 1. A first slewing bearing 3 is installed on the slide plate 2. A platform plate 4 is fixedly installed on the inner ring of the first slewing bearing 3. A continuous conveying mechanism capable of vertical lifting, vertical rotation and lateral movement is further installed on the platform plate 4.

[0021] Among them, the longitudinal movement of the slide plate 2, the vertical lifting and lateral movement of the continuous conveying mechanism can be realized by an oil cylinder or a rack and pinion drive mechanism, and the vertical rotation of the continuous conveying mechanism can be realized by a rotary oil cylinder or a slewing bearing drive.

[0022] To improve the stability of the whole machine positioning in the roadway during operation, a support cylinder 5 arranged vertically is installed on the slide plate 2. The support cylinder 5 penetrates upward through the center positions of the first slewing bearing 3 and the platform plate 4. A support foot nail 6 is installed at the end of the piston rod of the support cylinder 5. The rotation of the platform plate 4 does not affect the position of the support cylinder 5, and the support cylinder 5 can longitudinally move together with the slide plate 2. When the piston rod of the support cylinder 5 extends, it can drive the support foot nail 6 to tightly abut against the top wall position of the roadway upward, so as to stably position the whole material propulsion vehicle at a set position in the roadway, facilitating subsequent explosive pushing operations.

[0023] As Figures 6 - 8 shown, the continuous conveying mechanism includes a conveying frame 7. The conveying frame 7 can be adjusted longitudinally, laterally, vertically, horizontally rotationally and vertically rotationally relative to the crawler vehicle 1. Two sets of conveying components arranged side by side are provided on the conveying frame 7. Each conveying component includes a first sprocket 8 and a second sprocket 9 arranged up and down. A transmission chain 10 is installed in cooperation between the first sprocket 8 and the second sprocket 9. The rotation directions of the transmission chains 10 of the two sets of conveying components are opposite. In Figure 6In the shown direction, the drive chain 10 located at the left position rotates counterclockwise, and the drive chain 10 located at the right position rotates clockwise.

[0024] A number of pressing blocks 11 are installed on the outer periphery of the drive chain 10. Clamping grooves 12 are formed in each pressing block 11. A push rod 13 is clamped and installed between the pressing blocks 11 between adjacent conveying components. The push rod 13 is located in the space enclosed by the clamping grooves 12 on both sides. A hydraulic motor 14 is installed on the conveying frame 7. The output shaft of the hydraulic motor 14 is connected to the rotating shaft of the second sprocket 9. When the hydraulic motor 14 is started, the drive chains 10 of the two conveying components rotate in opposite directions, and the upward continuous pushing of the push rod 13 is realized through the clamping and rotation feeding of the pressing blocks 11.

[0025] To realize the feeding guidance of the push rod 13, a vertical rod 15 is also installed on the conveying frame 7. A number of guiding frames 16 are arranged on the side surface of the vertical rod 15. The guiding frames 16 are located between the two conveying components. A clamping wheel 17 matched with the push rod 13 is arranged in each guiding frame 16. The push rod 13 will enter into the clamping wheel 17 during the upward feeding process to form a necessary propulsion guidance and prevent the push rod 13 from deflecting before entering the blasting hole.

[0026] Furthermore, in order to adapt to the clamping and feeding of push rods 13 of different diameter types, the distance between the two conveying components can be adjusted adaptively. To achieve the above function, the conveying component includes a translation plate 18 that can move relative to the conveying frame 7. The first sprocket 8 and the second sprocket 9 are both installed on the translation plate 18. Horizontal guide rods 19 are installed at the upper and lower ends of the conveying frame 7. Guide sleeves 20 matched with the guide rods 19 are installed on the translation plate 18. A lead screw 21 is installed on the conveying frame 7. One end of the lead screw 21 is installed with a handle 22. Threaded nut sleeves 23 matched with the lead screw 21 are installed on the translation plates 18 of the two conveying components. The internal threads of the two threaded nut sleeves 23 have opposite helix directions. When the handle 22 is rotated to drive the lead screw 21 to rotate, the two conveying components can move closer or farther away, so as to adjust the distance between the pressing blocks 11 on the two conveying components and adapt to the clamping of push rods 13 of different diameter types.

[0027] In order to enable the continuous conveying mechanism, after the position adjustment is completed, the vertical rod 15 serving as the guide of the push rod 13 can be tightly pressed against the position of the blasting hole opened in the roadway, an expansion rod 24 is installed inside the vertical rod 15 in a matching manner. A number of guiding frames 16 are arranged on the side surface of the expansion rod 24. A jacking oil cylinder 25 is installed between the conveying frame 7 and the expansion rod 24. The end of the piston rod of the jacking oil cylinder 25 is hinged and installed on the expansion rod 24.

[0028] When the position of the continuous conveying mechanism is adjusted, the piston rod of the jacking oil cylinder 25 is in a contracted state, so that the telescopic rod 24 does not extend too much out of the vertical rod 15 to avoid structural interference with the roadway. After the position is adjusted, the piston rod of the jacking oil cylinder 25 extends, and the guide frame 16 at the end of the telescopic rod 24 is tightly pressed against the position of the hole opened on the inner wall of the roadway. Then, the push rod 13 can accurately enter the blast hole during the subsequent feeding process, realizing the continuous pushing of the explosive.

[0029] Further, in order to keep the drive chain 10 in the conveying assembly in a tensioned state and drive the pressing block 11 to rotate reciprocally to realize the clamping and feeding of the push rod 13, a tension adjustment device is installed in the conveying assembly, as Figure 9 shown. The tension adjustment device includes a tensioning seat 26. A tensioning sleeve 27 is arranged in the tensioning seat 26. A tensioning bolt 28 is fitted in the tensioning sleeve 27. The tensioning bolt 28 is located at the bottom of the rotating shaft of the first sprocket 8. Rotating the tensioning bolt 28 can push the rotating shaft of the first sprocket 8 upward, thereby extending the distance between the first sprocket 8 and the second sprocket 9 and keeping the drive chain 10 always in a tensioned state. The rotating shafts of the first sprocket 8 and the second sprocket 9 can be pressed on the long slot of the conveying frame 7 through nuts to realize the lifting adjustment of the height positions of the first sprocket 8 and the second sprocket 9 on the conveying frame 7.

[0030] Further, in order to realize the positioning installation of the push rod 13 between the two conveying assemblies, a horizontally arranged guiding frame plate 29 is installed at the bottom of the conveying frame 7. Limiting wheels 30 are arranged around the bottom of the guiding frame plate 29. The push rod 13 passes through the guiding frame plate 29 upward and enters between the two conveying assemblies. The surrounding limiting wheels 30 realize the limiting of the push rod 13 and do not affect the normal feeding of the push rod 13. In order to protect the moving parts in the conveying assembly, a protective cover 31 is also provided on the outer periphery of each conveying assembly. A necessary space is reserved at the inner side position of the protective cover 31 to ensure the normal clamping and feeding of the push rod 13 by the pressing blocks 11 on the two side conveying assemblies.

[0031] Further, in order to realize the longitudinal movement drive of the sliding plate 2, as Figure 10 shown, a longitudinal movement oil cylinder 32 is installed on the crawler vehicle 1. The cylinder barrel of the longitudinal movement oil cylinder 32 is fixedly provided with the sliding plate 2. A longitudinal movement slide rail 33 matched with the sliding plate 2 is also arranged on the crawler vehicle 1. The piston rod of the longitudinal movement oil cylinder 32 can be fixed on the crawler vehicle 1. When hydraulic oil is supplied, the cylinder barrel of the longitudinal movement oil cylinder 32 can move relative to the piston rod, thereby driving the sliding plate 2 to move longitudinally synchronously.

[0032] Further, in order to realize the vertical lifting, vertical rotation and lateral movement of the conveying frame 7 and the conveying assembly thereon relative to the platform plate 4, as Figure 11 and Figure 12As shown in the figure, a lifting oil cylinder 34 is installed on the platform plate 4. The piston rod of the lifting oil cylinder 34 is hinged on the platform plate 4, and a guide sleeve frame 35 that cooperates with the support cylinder 5 is installed on the cylinder barrel of the lifting oil cylinder 34. The lifting oil cylinder 34 can drive the guide sleeve frame 35 to move up and down along the vertical direction of the support cylinder 5.

[0033] On one side of the guide sleeve frame 35, a vertically arranged second slewing bearing 36 is installed. A rotating vertical plate 37 is installed on the inner ring of the second slewing bearing 36. A transverse movement guide rail 38 is provided on the rotating vertical plate 37. A transverse movement vertical plate 39 is installed in cooperation with the transverse movement guide rail 38. The conveying frame 7 is fixedly arranged on the transverse movement vertical plate 39. A transverse movement oil cylinder 40 is installed between the rotating vertical plate 37 and the transverse movement vertical plate 39. The cylinder barrel of the transverse movement oil cylinder 40 is hinged and installed on the transverse movement vertical plate 39, and the piston rod of the transverse movement oil cylinder 40 is hinged and installed on the rotating vertical plate 37. The transverse movement oil cylinder 40 can drive the transverse movement vertical plate 39 to move horizontally relative to the rotating vertical plate 37, and the second slewing bearing 36 can drive the rotating vertical plate 37 to rotate in the vertical direction.

[0034] In the above structure, the lifting oil cylinder 34 can drive the conveying frame 7 and the conveying components thereon to move vertically up and down, the second slewing bearing 36 can drive the conveying frame 7 and the conveying components thereon to rotate vertically, and the transverse movement oil cylinder 40 can drive the conveying frame 7 and the conveying components thereon to move horizontally. Thus, various position adjustments of the conveying frame 7 and the conveying components thereon relative to the platform plate 4 are realized.

[0035] The continuous pushing construction process of the continuous conveying type material pushing vehicle of the present invention is as follows: The crawler vehicle 1 moves to the designated drilling position in the roadway. After the piston rod of the support cylinder 5 extends and is positioned, the lifting oil cylinder 34 is controlled to work to adjust the up and down movement of the conveying frame 7, thereby driving the continuous conveying mechanism to adjust the vertical height. When the conveying component reaches the set height, the slewing bearing is controlled to work to adjust the included angle between the conveying component and the vertical plane. When the conveying axis of the conveying component coincides with the axis of the blasting hole, the slewing bearing stops rotating. Then, the jacking oil cylinder 25 is controlled to make the extended telescopic rod 24 and the guide frame 16 press tightly against the construction wall surface where the hole is drilled, so as to achieve the purpose of fixing the conveying component. When continuously pushing the explosive pipe, first, one end of the push rod 13 is installed between the two side conveying components. The hydraulic motor 14 drives the pressing block 11 on the transmission chain 10 to reciprocate and rotate, and then the pressing block 11 drives the push rod 13 to clamp and move upward, realizing the continuous conveying of the explosive pipe.
