Description

Technical Field

[0001] This application relates to the field of mining blasting equipment, and in particular to an underground explosives mixing vehicle with conveying pipe protection and sealing function. Background Technology

[0002] The underground explosives mixing vehicle is one of the main pieces of equipment used in underground blasting in mines. It typically consists of a vehicle body, a hose reel, a material conveying hose, a hole alignment mechanism, a pipe delivery mechanism, and a pumping system. When blasting is required, explosive holes are pre-drilled on the ground. The vehicle body travels to the target location, and the hole alignment mechanism aligns the material conveying hose on the hose reel with the position of the explosive hole. Subsequently, the pipe delivery mechanism sends the material conveying hose into the explosive hole. Next, the pumping system transports the emulsified mixed explosives from the hopper to the bottom of the explosive hole through the material conveying hose. Finally, a sensitizer and a detonating cord are added to the explosive hole to achieve blasting.

[0003] However, since the conveying hose is wound on the hose reel, the hose itself has a curved arc during the process of conveying it into the explosive hole, making it easy to collide with the hole wall. In addition, there may be sharp protruding stones on the inner wall of the explosive hole, which will cause the conveying hose to be worn during the lowering process, thus reducing the service life of the conveying hose. Summary of the Invention

[0004] To reduce the risk of wear on the conveying hose when feeding materials into the explosive hole, this application provides an underground explosive mixing vehicle with conveying hose protection and hole sealing functions.

[0005] The technical solution provided in this application for an underground explosives mixing vehicle with conveying pipe protection and sealing function is as follows:

[0006] It includes a vehicle body, a hopper, a feeding pump, and a conveying hose. The vehicle body is equipped with a feeding auxiliary component, which includes a lifting mechanism and a guide tube. The lifting mechanism is connected to the vehicle body, and the guide tube is installed on the lifting mechanism. One end of the guide tube is connected to the feeding hose, and the other end of the guide tube can be connected to the explosive hole on the ground by a plug-in connection. The end of the guide tube away from the feeding hose is provided with a limiting boss, which can abut against the ground at the edge of the explosive hole.

[0007] By adopting the above technical solution, when it is necessary to put mixed explosives into the explosive hole, the conveying hose can be connected to the guide tube first, and the other end of the guide tube away from the conveying hose can be inserted into the explosive hole, so that the limiting protrusion on the guide tube abuts against the ground, thereby initially fixing the position of the guide tube. Subsequently, when the explosive material is conveyed through the conveying hose, the explosive material will enter the explosive hole through the guide tube. The entire process does not require the conveying hose to be inserted into the explosive hole, thereby reducing the risk of the conveying hose being torn due to friction with the hole wall when it is lowered or retrieved into the explosive hole, thus protecting the hose.

[0008] Optionally, the lifting mechanism includes a connecting seat, a lifting component, a first mounting plate, a second mounting plate, and a first pushing component. The connecting seat is connected to the vehicle body. The lifting component is installed on the connecting seat and connected to the first mounting plate. The lifting component is used to realize the lifting and lowering of the first mounting plate on the connecting seat. The second mounting plate is hinged to the first mounting plate and can abut against the ground. One end of the first pushing component is installed on the first mounting plate, and the other end of the first pushing component is installed on the second mounting plate. The first pushing component is used to realize the up-and-down flipping of the second mounting plate relative to the first mounting plate. The drug delivery tube is flexibly installed on the second mounting plate.

[0009] By adopting the above technical solution, when the catalytic converter needs to be connected to the explosive hole on the ground, the lifting component can drive the first mounting plate to rise and fall, so that the second mounting plate can rise and fall together with the first mounting plate. At the same time, the pushing component can adjust the angle between the first mounting plate and the second mounting plate within a certain range, so that the second mounting plate can abut against the slope at different angles, thus making the catalytic converter suitable for explosive holes with the axis perpendicular to the slope.

[0010] Optionally, the second mounting plate is provided with two sets of drive units. The two sets of drive units are symmetrically distributed on both sides of the guide tube with the axis of the guide tube as the axis of symmetry. The drive unit includes a drive roller and a drive motor for driving the drive roller to rotate around its own axis. The drive motor is mounted on the second mounting plate and connected to the drive roller by belt drive. When the output shaft of the drive motor starts to rotate, the drive roller starts to rotate around its own axis together. The drive roller is provided with a drive part whose curvature is adapted to the contour of the outer wall of the guide tube. The drive part can abut against the outer wall of the guide tube.

[0011] By adopting the above technical solution, when the drive motor starts and drives the drive roller to rotate around its own axis, the drive part on the drive roller is pressed against the outer wall of the guide tube, so that the guide tube can rise and fall with the forward or reverse rotation of the drive roller. This allows the guide tube to rise and fall on the mounting plate 2, thereby avoiding the guide tube from colliding directly with the ground or slope due to inaccurate positioning of the explosive hole, and thus preventing the guide tube from being easily damaged.

[0012] Optionally, the drive unit also includes a sliding seat and a second pusher. The sliding seat is mounted on the second mounting plate and can slide on the second mounting plate. The second pusher is mounted on the second mounting plate and is used to enable the sliding seat to slide on the second mounting plate in a direction closer to or away from the drug delivery tube. The drive motor and the drive roller are both mounted on the sliding seat.

[0013] By adopting the above technical solution, when the pusher changes the angle between the mounting plate 1 and the mounting plate 2, the distance between the two drive rollers can be changed by the pusher, so that there is an adjustable gap when the guide tube is located between the two drive rollers, and thus the angle of the guide tube on the mounting plate 2 can be adjusted.

[0014] Optionally, a limiting rod is provided on the second mounting plate, and a guide groove is provided on the outer wall of the medicine guide tube. One end of the limiting rod is installed on the second mounting plate and its axis is perpendicular to the axis of the medicine guide tube. The limiting rod is used to limit the lifting stroke of the medicine guide tube, and the medicine guide tube can rotate around the axis of the limiting rod.

[0015] By adopting the above technical solution, when the drive roller drives the guide tube to rise and fall on the second mounting plate, the guide groove on the guide tube also rises and falls with the rise and fall of the guide tube, and then rises and falls relative to the limit rod. The end of the limit rod is located in the guide groove. In addition to guiding the rise and fall of the guide tube, it can also prevent the guide tube from falling off the second mounting plate by abutting against the sides of the guide groove at both ends.

[0016] Optionally, the mounting plate two is further provided with a mounting base, a pushing component three is mounted on the mounting base, and an adjusting component is mounted on the pushing component three. The adjusting component includes an adjusting part and a connecting part that are fixedly connected. The connecting part is connected to the pushing component three, and the adjusting part is connected to the drug delivery tube. The adjusting part is used to adjust the included angle between the drug delivery tube and the mounting plate two.

[0017] By adopting the above technical solution, a mounting base is provided on the mounting plate 2, and a pusher 3 is installed on the mounting base. An adjusting part is provided on the pusher 3, which allows the adjusting part of the adjusting part to be connected to the end of the drug guide tube near the conveying hose. At the same time, through the action of the pusher 3, the drug guide tube can rotate around the axis of the limiting rod, thereby realizing the angle adjustment between the drug guide tube and the mounting plate 2.

[0018] Optionally, the adjusting part is provided with a guide rod, one end of which is connected to the adjusting part and the other end of which is located in the guide groove. The guide rod is used to drive the drug delivery tube to rotate around the axis of the limiting rod.

[0019] By adopting the above technical solution, the end of the guide rod is located in the guide groove, so that when the pusher three is started, the adjusting part on the pusher three can push the end of the drug guide tube connected to the conveying hose to rotate around the axis of the limiting rod through the guide rod, thereby adjusting the angle between the drug guide tube and the mounting plate two.

[0020] Optionally, the outer diameter of the limiting boss gradually decreases from the direction closest to the conveying hose toward the direction furthest from the conveying hose.

[0021] By adopting the above technical solution, the outer diameter of the limiting boss gradually decreases from the direction close to the conveying hose to the direction away from the conveying hose. This allows the limiting boss to abut against the edge of the explosive hole when the guide tube needs to be inserted into the vertical explosive hole on the slope, thereby sealing the explosive hole during delivery and reducing the risk of explosive material leaking from the explosive hole.

[0022] Optionally, the inner diameter of the drug delivery tube gradually decreases from the direction closest to the delivery tube toward the direction furthest from the delivery tube.

[0023] By adopting the above technical solution, the diameter of the inner wall of the guide tube gradually decreases from the direction close to the conveying hose to the direction away from the conveying hose. This causes the explosive material to concentrate at the axis position of the guide tube when it passes through the guide tube, thereby reducing the occurrence of the explosive material adhering to the inner wall of the explosive hole during the descent.

[0024] In summary, this application includes at least the following beneficial technical effects:

[0025] 1. By setting up a guide tube, the conveying hose will not rub against the inner wall of the explosive hole when it needs to deliver explosive material into the explosive hole. This reduces the probability of the conveying hose breaking, thereby extending the service life of the conveying hose and reducing economic costs.

[0026] 2. By setting a limiting boss on the delivery tube with an outer diameter that gradually decreases from near the delivery hose to away from the delivery hose, the limiting boss can achieve a sealing effect on the explosive hole when the delivery tube is connected to the explosive hole on the ground or on the slope.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses an underground explosives mixing vehicle with conveyor pipe protection and sealing functions, referring to... Figure 1 , Figure 2 and Figure 3 The device includes a vehicle body 1, a hopper 2, a feeding pump 3, a conveying hose 4 wound on a roller, and a feeding auxiliary component 5 installed on the vehicle body 1. The feeding pump 3 is used to convey the emulsified explosive material in the hopper 2 through the conveying hose 4 to the feeding auxiliary component 5, and finally convey it to the explosive hole through the feeding auxiliary component 5.

[0035] The feeding auxiliary component 5 includes a lifting mechanism 6 and a guide tube 7. One end of the guide tube 7 is the feeding end, and the other end is the discharging end. The feeding end is connected to the conveying hose 4, allowing the conveying hose 4 to transport explosives into the guide tube 7. The discharging end is inserted into a pre-drilled explosive hole on the ground. To limit the distance the guide tube 7 is inserted into the explosive hole, a limiting boss 8 is provided on the outer wall of the guide tube 7 near the discharging end. The diameter of the outer wall of the limiting boss 8 is from the feeding end... The material end gradually decreases in size towards the discharge end, eventually forming a cone shape. This allows the limiting boss 8 to not only limit the material guide tube 7 when it is inserted into the explosive hole on the ground, but also to increase the sealing between the material guide tube 7 and the explosive hole. At the same time, when the explosive hole is vertically opened on the slope, the limiting boss 8 can also abut against the edge of the explosive hole on the slope, thereby limiting the material guide tube 7 and increasing the sealing between the material guide tube 7 and the edge of the explosive hole.

[0036] In order to reduce the probability of explosive material adhering to the inner wall of the explosive hole when the explosive material is conveyed into the explosive hole, the inner diameter of the explosive material guide tube 7 also gradually decreases from the feed end to the discharge end. This means that after the discharge end of the explosive material guide tube 7 is inserted into the explosive hole, the explosive material is fed in from a position close to the axis of the explosive hole, thereby reducing the probability of the explosive material adhering to the inner wall of the explosive hole.

[0037] Reference Figure 2 and Figure 4 The lifting mechanism 6 includes a connecting seat 9, a lifting component 10, a first mounting plate 11, a second mounting plate 12, and a first pushing component 13. The second mounting plate 12 is a bent sheet metal, with the middle section of its cross-section higher than the sides. The connecting seat 9 is mounted on the vehicle body 1. The lifting component 10 consists of a lead screw and a motor connected to it. The connecting seat 9 has a groove for holding the lead screw. The first mounting plate 11 has a sliding part that slides within the groove, and a lead screw nut adapted to the lead screw is located within the sliding part. When the lead screw rotates around its own axis within the groove, the first mounting plate 11 rises and falls on the connecting seat 9. The first pushing component 13 is a hydraulic cylinder and an electric push rod. The first pushing component 13 is hinged to the side wall of the first mounting plate 11 away from the connecting seat 9. The movable end of the first pushing component 13 is connected to the connecting seat 9. Mounting plate 2 12 is hinged, and mounting plate 2 12 is hinged to mounting plate 1 11. In the initial state, mounting plate 1 11 and mounting plate 2 are perpendicular to each other, and mounting plate 2 12 is parallel to the ground. This allows the pusher to adjust the angle between mounting plate 1 11 and mounting plate 2 12 by extending or retracting its movable end. The guide tube 7 is vertically mounted on mounting plate 2 12. This allows mounting plate 2 12 to rise and fall along with the screw when it starts to rotate, so that the guide tube 7 can be inserted into the explosive hole and then pulled out of the explosive hole after insertion. The angle adjustment between mounting plate 1 11 and mounting plate 2 12 allows it to be used on slopes of different angles when mounting plate 2 12 is in contact with the ground, and also increases the stability of the guide tube 7 when inserted into the explosive hole.

[0038] Reference Figure 4 and Figure 5Two sets of drive units 14 are provided on the mounting plate 2 12. The two sets of drive units 14 are symmetrically distributed on both sides of the guide tube 7 with the axis of the guide tube 7 as the axis. The drive unit 14 includes a drive roller 15, a drive motor 16, a sliding seat 18, and a pusher 2 19. The pusher 2 19 is an electric push rod. The sliding seat 18 is mounted on the mounting plate and can slide on the mounting plate in a direction closer to or away from the guide tube 7. The pusher is mounted on the mounting plate 2 12 and its movable end is connected to the sliding seat 18 to realize the sliding of the sliding seat 18 on the mounting plate 2 12. The drive roller 15 and the drive motor 16 are both mounted on the sliding seat 18. The drive motor 16 is used to drive the drive roller 15 to rotate around its own axis.

[0039] A drive part 17 with an arc that matches the outer wall of the drug guide tube 7 is provided on the outer wall of the drive roller 15, and the drive part 17 can press against the outer wall of the drug guide roller under the action of the pusher 2 19, so that when the drive roller 15 rotates, the drive roller 15 can drive the drug guide tube 7 to rise and fall on the mounting plate 2 12.

[0040] At this time, when the mounting plate 2 12 is about to come into contact with the ground, the two sides of the mounting plate 2 12 will first come into contact with the ground, and then the guide tube 7 will be raised and lowered on the mounting plate 2 12 under the action of the drive roller, and then inserted into the explosive hole on the ground until the limiting boss 8 is pressed against the edge of the explosive hole.

[0041] Furthermore, a rubber layer can be provided on the outer wall of the drive unit 17 to increase the friction between the drive unit 17 and the drug delivery tube 7.

[0042] Two guide grooves 21 extending parallel to the axis of the drug delivery tube 7 are provided on the outer wall of the drug delivery tube 7. The two guide grooves 21 are also symmetrically distributed on both sides of the guide tube with respect to the axis of the drug delivery tube 7, and their positions are offset from the position of the drive roller 15. The two ends of the guide grooves 21 are closed. On the mounting plate 22, corresponding to the position of the guide grooves 21, there is a limit rod 20. One end of the limit rod 20 is fixed on the mounting plate 22, and the other end is located in the guide groove 21 and does not abut against the guide groove 21. This makes it so that when the pusher 2 19 drives the drive roller 15 to move, the drug delivery tube 7 will not easily fall off the mounting plate 22 after losing the abutment between it and the drive roller 15.

[0043] Mounting plate 212 is also provided with mounting base 22, on which pusher 23 is mounted. Pusher 23 is also an electric push rod. Adjustment component 24 is provided on the movable end of pusher 23. Adjustment component 24 includes an adjustment part 26 and a connecting part 25 that are fixedly connected. The connecting part 25 is connected to the movable end of pusher 23. Guide rod 27 is provided on adjustment part 26. The axis of guide rod 27 is parallel to the axis of limit rod 20. One end of guide rod 27 is fixedly connected to adjustment component 24, and the other end of guide rod 27 is located in guide groove 21. This allows the drug delivery tube 7 to rotate around the axis of limit rod 20 when pusher 23 extends or retracts, thereby realizing the angle adjustment between drug delivery tube 7 and mounting plate 212.

[0044] The implementation principle of this application embodiment is as follows: First, the vehicle body 1 is driven to the explosive hole where explosive material needs to be input. Then, the lifting component 10 is started. The lifting component 10 drives the mounting plate 11 to descend, and at the same time drives the mounting plate 112 to move and descend. When the mounting plate 122 comes into contact with the ground, and the position of the guide tube 7 is aligned with the position of the explosive hole, the drive motor 16 is started to drive the drive tube to start rotating around its own axis, so that the discharge end of the guide tube is connected to the explosive hole on the ground by a plug-in connection.

[0045] When explosives need to be fed into the explosive hole on the slope, if the axis of the explosive hole is perpendicular to the ground, the extension length of the pusher 13 is changed to adjust the angle between the mounting plate 22 and the mounting plate 11, so that the mounting plate 212 can be parallel to the slope. Then, the pusher 29 and the pusher 3 23 move together. The two pushers 29 retract simultaneously, so that the guide tube 7 has space on the mounting plate 212 to start rotating around the axis of the limiting rod 20. The pusher 3 23 ensures that the guide tube 7 is always in a certain position during the rotation. The guide tube 7 is pressed against the drive part 17 on the drive roller 15, so that the guide tube 7 will not easily fall off the mounting plate 2 12. When the axis of the guide tube 7 is adjusted to be perpendicular to the ground, the pusher 2 19 is pushed out again to clamp the guide tube 7 so as to continue to lift the guide tube 7 on the mounting plate 2 12. Then the mounting plate 11 descends so that the mounting plate 2 12 comes into contact with the slope. Then the drive roller 15 starts to rotate under the action of the drive motor 16, so that the guide tube 7 starts to be inserted into the explosive hole on the slope, and then the explosive material is continued to be conveyed into the explosive hole.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
