Description

Technical Field

[0001] This invention relates to the field of borehole charging technology, and in particular to an automatic borehole charging device and method. Background Technology

[0002] The drill-and-blast method, also known as the drilling-and-blast method, is a method of excavating rock by drilling, loading explosives, and blasting. This method has evolved from the early days of manually drilling holes with chisels and hammers and detonating individual explosive charges one by one with detonators, to drilling holes with rock drilling rigs or multi-arm drilling rigs and applying blasting techniques such as millisecond blasting, pre-splitting blasting, and smooth blasting. Currently, in the drill-and-blast method for rock tunnels, after drilling, the explosives are still manually inserted, which is slow and has a low degree of automation.

[0003] The patent publication number CN217424144U discloses a "tunnel borehole charging device," which includes a delivery tube, an external fixing tube, a propellant cartridge abutment tube, a fixing component, and a positioning pad. The delivery tube is slidably disposed inside the external fixing tube, and a horizontal slot is pre-formed on the delivery tube along its extension direction. The fixing component securely connects the external fixing tube and the propellant cartridge abutment tube via a first fixing hole pre-drilled on it, the horizontal slot pre-drilled on the delivery tube, and a second fixing hole pre-drilled on the propellant cartridge abutment tube. The positioning pad is fitted onto the rear end of the delivery tube and is used to tighten the borehole when the front section of the delivery tube reaches a predetermined position. This device enables the entire tunnel borehole charging process in a compact and easily operable manner, significantly improving operational efficiency, and is reusable. While this device achieves improved operational efficiency during charging, it still requires the propellant tube to be gradually fed into the borehole during use, resulting in low overall automation and relatively complex operation.

[0004] To address these issues, the present invention provides an automatic charging device and method for blast holes. Summary of the Invention

[0038] 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.

[0039] The purpose of this invention is to provide an automatic gun barrel loading device and method to solve the problems existing in the prior art. It can realize automatic positioning of the gun barrel and automatic and continuous filling of the gun barrel, with a high degree of automation and simple operation.

[0040] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] The feeding assembly 5 includes a feeding plate 51 and a residual gear 54. The feeding plate 51 has a feeding groove 52 inside and a wire groove 56 inside. A second rack 53 is fixedly installed at the bottom of the feeding plate 51, and the residual gear 54 meshes with the second rack 53.

[0043] The filling component 3 includes a first rack 31 and a first gear 35. The first gear 35 meshes with the first rack 31. A filling block 36 is fixedly installed on the end face of the first rack 31. A spring telescopic rod 38 is fixedly installed on the side of the filling block 36. A sensing block 37 is fixedly installed on the end face of the spring telescopic rod 38.

[0044] In one embodiment, the adjustment assembly 2 includes a hydraulic rod 21, which is fixedly mounted on the top of the movable base 1. A support rod 22 is fixedly mounted on the top of the hydraulic rod 21, and a top plate 27 is hinged to the top of the support rod 22.

[0045] It should be noted that by activating the hydraulic rod 21, the upper support rod 22 and the top plate 27 are moved upward synchronously, thereby facilitating the adjustment of the height of the guide cylinder 42.

[0046] In one embodiment, a groove 23 is provided inside the support rod 22, and a first screw 25 is rotatably connected inside the groove 23. A slider 24 is screwed to the outside of the first screw 25. A connecting rod 26 is hinged between the slider 24 and the top plate 27. A motor is fixedly installed inside the support rod 22, and the output shaft of the motor is fixedly connected to the first screw 25.

[0047] It should be noted that by starting the motor to drive the first screw 25 to rotate, the slider 24 will slide inside the slide groove 23. Then, the connecting rod 26 can drive the top plate 27 to rotate around the support rod 22, thereby realizing the angle adjustment between the top plate 27 and the guide cylinder 42.

[0048] In one embodiment, the feeding assembly 5 further includes a second motor 55 and a side block 57. The second motor 55 and the side block 57 are both fixedly mounted on the top of the top plate 27. The residual gear 54 is fixedly mounted on the output of the second motor 55. A lever 59 is fixedly mounted on the outside of the output shaft of the second motor 55. A second control switch 58 is movably mounted on the side of the side block 57. One end of the lever 59 is located above the second control switch 58.

[0049] In one embodiment, starting the second motor 55 can drive the residual gear 54 to rotate. The rotating residual gear 54 cooperates with the second rack 53 to realize the intermittent movement of the feeding plate 51, placing the medicine tubes to be filled in the feeding trough 52 in advance. The intermittent movement of the feeding plate 51 can realize the automatic filling of the medicine tubes. After the medicine tubes with leads are placed in the feeding trough 52, the leads are placed in the wire groove 56, so that the medicine tubes with leads are not affected when entering the guide cylinder 42. When the second motor 55 rotates, the lever 59 can move the second control switch 58. The second control switch 58 can control the starting and forward and reverse rotation of the first motor 33.

[0050] In one embodiment, the auxiliary component 6 includes a bottom block 61 and an internal groove 63. The bottom block 61 is fixedly mounted on the top of the top plate 27, and the internal groove 63 is fixedly mounted on the bottom of the feeding plate 51. The bottom block 61 has an internal groove 63 inside, and the internal groove 63 is elastically connected to a clamping plate 64 by an auxiliary spring 65. The clamping plate 64 is located on the left and right sides of the limiting plate 62.

[0051] It should be noted that when the feeding plate 51 moves, the lower limiting plate 62 moves between the two clamping plates 64, which creates a partial resistance to the movement of the feeding plate 51, thus making the feeding plate 51 more stable when it moves.

[0052] In one embodiment, the guide assembly 4 includes a guide cylinder 42, which is fixedly installed on the top of the top plate 27. A movable groove 44 is provided on the outer side of the guide cylinder 42. A guide plate 43 is slidably connected inside the movable groove 44. A second screw 45 is screwed inside the guide plate 43. An auxiliary block 41 is fixedly installed on the end face of the guide cylinder 42. The second screw 45 is rotatably connected to the side of the auxiliary block 41.

[0053] It should be noted that the rotation of the second screw 45 can drive the guide plate 43 to move. After the guide cylinder 42 is placed inside the borehole, the movement of the guide plate 43 fills the inside of the borehole, so that the propellant tube will not be affected by the uneven inner wall of the borehole after entering the borehole.

[0054] In one embodiment, the auxiliary block 41 is located above the feeding plate 51. The bottom of the auxiliary block 41 and the feeding trough 52 form a complete cylinder. The interior of the auxiliary block 41 and the feeding trough 52 are interconnected with the interior of the guide cylinder 42. A motor is fixedly installed inside the auxiliary block 41, and the output shaft of the motor is fixedly connected to the second screw 45.

[0055] It should be noted that the motor facilitates the rotation of the second screw 45, and the auxiliary block 41 facilitates the entry of the medicine tube inside the feeding trough 52 into the guide cylinder 42.

[0056] In one embodiment, the filling component 3 further includes a fixing block 32, a support rod 34 is fixedly installed at the bottom of the fixing block 32, the support rod 34 is fixedly installed at the top of the top plate 27, a first gear 35 is rotatably connected inside the fixing block 32, a first rack 31 is slidably connected inside the fixing block 32, a first motor 33 is fixedly installed on the outside of the fixing block 32, and the output shaft of the first motor 33 passes through the inner wall of the fixing block 32 and is fixedly connected to the first gear 35.

[0057] It should be noted that by starting the first motor 33, the first gear 35 is driven to rotate, which in turn drives the first rack 31 to move, which in turn drives the filling block 36 and the sensing block 37 to move, thereby pushing the medicine tube inside the feeding trough 52 into the guide cylinder 42, thus completing the filling of the medicine tube.

[0058] In one embodiment, a first control switch 310 is movably mounted on the side of the filling block 36, and a pressure rod 39 is fixedly mounted on the side of the sensing block 37. The pressure rod 39 and the first control switch 310 are aligned with each other, and the positions of the sensing block 37 and the filling block 36 are aligned with the positions of the cylinder formed by the auxiliary block 41 and the feeding trough 52.

[0059] It should be noted that the pressure rod 39 can press the first control switch 310, and the first control switch 310 can control the start and forward / reverse rotation of the first motor 33.

[0060] This application also discloses an automatic charging method for blast holes, including the following steps:

[0061] Step 1: Insert the guide tube 42 into the borehole, and move the guide plate 43 inward according to the length of the borehole. This will allow the guide tube 42 and the guide plate 43 to fit into the borehole, making it easier to insert the propellant tube into the borehole.

[0062] Step 2: Adjust the height of the guide cylinder 42 by using the hydraulic rod 21, and move the connecting rod 26 by moving the slider 24 to adjust the angle of the top plate 27, thereby adjusting the angle of the guide cylinder 42, so as to adjust the equipment according to the angle and height of the blast hole;

[0063] Step 3: The first motor 33 drives the first gear 35 to move the first rack 31, which in turn moves the filling block 36 and the sensing block 37. The filling block 36 and the sensing block 37 are used to load the propellant tube in the loading trough 52 into the borehole.

[0064] Step 4: The second motor 55 drives the residual gear 54 to cooperate with the second rack 53 to realize the intermittent movement of the feeding plate 51, so that after the previous medicine tube is filled, the next medicine tube can be automatically transported to the filling position.

[0065] In practice, the height of the guide cylinder 42 is first adjusted by adjusting the hydraulic rod 21. Then, the angles of the top plate 27 and the guide cylinder 42 are adjusted by adjusting the slider 24 and the connecting rod 26. The entire device is moved by moving the base 1, which facilitates the accurate insertion of the guide cylinder 42 into the borehole. After the guide cylinder 42 is inserted into the borehole, the guide plate 43 is unfolded to facilitate the filling of the propellant tube.

[0066] The intermittent movement of the feeding plate 51 ensures that the feeding trough 52 is aligned with the inside of the guide cylinder 42 after each movement. The medicine tube is then fed into the guide cylinder 42 through the filling block 36 and the sensing block 37. After the residual gear 54 drives the feeding plate 51 to move a certain distance, the lever 59 will activate the second control switch 58 to start the first motor 33 to drive forward, thereby achieving automatic positioning of the medicine tube and automatic filling after positioning. When the medicine tube reaches the appropriate position, the sensing block 37 will press the filling block 36, and the pressure lever 39 will press the first control switch 310. At this time, the first control switch 310 controls the first motor 33 to reverse, moving the filling block 36 out of the guide cylinder 42, thus not affecting the subsequent movement of the feeding plate 51. This achieves automatic and continuous filling of the medicine tube, with a high degree of automation and simple operation.

[0067] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
