Description

Technical Field

[0001] This utility model belongs to the field of mining technology, specifically relating to a drilling device for blasting in open-pit mines. Background Technology

[0002] Currently, blasting is a common method used in mining operations. This requires drilling holes in advance, and then placing explosives or other blasting materials into the holes. However, existing drilling equipment uses a complex and inflexible mechanical structure for horizontal adjustment, requiring manual operation and multiple steps for adjustment. It is difficult to quickly move the position in different directions, which is not only time-consuming and labor-intensive, but also has low positioning accuracy. It is difficult to accurately move the drilling mechanism to the precise position required for blasting in mining operations, resulting in low drilling efficiency and an inability to meet the needs of complex terrain and diverse drilling requirements. Utility Model Content

[0003] This utility model addresses the aforementioned problems by providing a drilling device for blasting in open-pit mines.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a drilling device for blasting in open-pit mines, comprising a disc, three support columns mounted above the disc, a lifting mechanism mounted above the disc, a support plate mounted above the lifting mechanism, a sliding groove 1 and a sliding groove 2 formed above the support plate, the sliding groove 1 and the sliding groove 2 being perpendicular to each other, a sliding member slidably connected within the sliding groove 1 or the sliding groove 2, a drive motor 2 mounted above the sliding member, a drilling mechanism mounted at the output end of the drive motor 2, and groove 1 formed on each of the two adjacent sides of the sliding member, with drive mechanisms mounted at positions corresponding to the groove 1 and the groove 2 respectively.

[0005] Preferably, the lifting mechanism includes a worm gear and three connecting components. Each of the three connecting components includes two connecting plates and a rotating shaft. The two connecting plates are mounted above the disk. The worm gear passes through the upper and lower sides of the disk. A drive motor is mounted below the disk, and the output end of the drive motor is detachably connected to the end of the worm gear. The rotating shaft passes between the two connecting plates. A lifting component is mounted on the outer periphery of the rotating shaft. The upper part of the lifting component is fixedly connected to the lower part of the support plate. A worm wheel is mounted on the outer periphery of the rotating shaft, and the worm wheel meshes with the worm gear.

[0006] Preferably, the lifting assembly includes a connector and an inverted U-shaped frame. The connector is installed on the outer periphery of the rotating shaft, the inverted U-shaped frame is installed below the support plate, a rotating shaft is passed through the inverted U-shaped frame, an L-shaped frame is installed on the side of the connector, a U-shaped frame is installed above the L-shaped frame, a rotating shaft is passed through the U-shaped frame, and a connecting rod is installed between the outer periphery of the rotating shaft and the outer periphery of the rotating shaft.

[0007] Preferably, the driving mechanism includes an adsorption element and a cylinder. The cylinder is mounted on the side of the support plate via a support platform. The adsorption element is detachably connected to the piston rod end of the cylinder and engages with a groove.

[0008] Preferably, the drilling mechanism includes a guide rail and a servo motor. The guide rail is mounted on the output end of a drive motor, and the servo motor is mounted on the end of the guide rail. A ball screw is detachably connected to the output end of the servo motor, and a slider is fitted on the ball screw. The slider is slidably connected to the guide rail. A drive motor is mounted on the slider, and a drill bit is detachably connected to the output end of the drive motor.

[0009] Preferably, the second drive motor is externally connected to a controller, and the lifting mechanism, drilling mechanism and drive mechanism are all communicatively connected to the controller.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] (1) Existing drilling devices require manual operation for multiple steps in adjusting the horizontal position. However, this utility model has two mutually perpendicular sliding grooves, namely, groove 1 and groove 2, on the upper part of the support plate. The sliding component drives the drive motor 2 and the drilling mechanism to slide along groove 1 or groove 2. The sliding component is driven by the drive mechanism to slide, which facilitates quick switching between different groove directions. This greatly improves the efficiency and convenience of drilling position adjustment and can accurately move the drilling mechanism to any drilling position required for mining blasting.

[0012] (2) The worm gear rotates and drives the worm wheel to rotate, which in turn drives the rotating shaft to rotate, so that the L-shaped frame on the connecting piece drives the support plate to rise and fall through the connecting rod. The worm gear transmission has good self-locking performance, which can ensure that the support plate is stably fixed after it is raised and lowered to the appropriate position, avoiding slippage or shaking, and ensuring the overall stability of the device during drilling operations.

[0013] (3) The lifting mechanism can smoothly convert rotational motion into vertical lifting motion, reducing the impact and vibration during the lifting process, and improving the reliability and service life of the device;

[0014] (4) In the drilling mechanism, the second drive motor can drive the first guide rail to rotate, so as to realize the flexible adjustment of the drilling angle, which can meet the drilling needs of different angles and improve the applicability of the device.

[0015] (5) Servo motor 1, through the cooperation of ball screw and slider 1, can accurately control the feed movement of the drill bit in the drilling depth direction to ensure that the drilling depth meets the construction requirements; drive motor 3 drives the drill bit to rotate at high speed, providing powerful drilling power, and can efficiently carry out drilling operations on mine rocks.

[0025] Example 1

[0026] The following is in conjunction with the appendix Figure 1-4To further describe this utility model, a drilling device for blasting in open-pit mines, such as... Figure 1 , Figure 2 and Figure 4 As shown, the device includes a disc 2, three support columns 1 mounted on top of the disc 2, a lifting mechanism mounted on top of the disc 2, a support plate 9 mounted on top of the lifting mechanism, a sliding groove 1 and a sliding groove 2 provided on top of the support plate 9, the sliding groove 1 and the sliding groove 2 being perpendicular to each other, a sliding member 10 slidably connected in the sliding groove 1 or the sliding groove 2, a drive motor 2 12 mounted on top of the sliding member 10, a drilling mechanism mounted on the output end of the drive motor 2 12, and grooves 1 provided on both adjacent sides of the sliding member 10, with drive mechanisms installed at the corresponding positions of the sliding grooves 1 and 2.

[0027] like Figures 1-3 As shown, the lifting mechanism includes a worm gear 21 and three connecting assemblies. Each of the three connecting assemblies includes two connecting plates 3 and a rotating shaft. The two connecting plates 3 are mounted above the disc 2. The worm gear 21 passes through the upper and lower sides of the disc 2. A drive motor 11 is mounted below the disc 2. The output end of the drive motor 11 is detachably connected to the end of the worm gear 21. The rotating shaft passes between the two connecting plates 3. A lifting assembly is mounted on the outer periphery of the rotating shaft. The upper part of the lifting assembly is fixedly connected to the lower part of the support plate 9. A worm wheel 20 is mounted on the outer periphery of the rotating shaft, and the worm wheel 20 meshes with the worm gear 21.

[0028] like Figure 1 and Figure 2 As shown, the lifting assembly includes a connector 5 and an inverted U-shaped frame 8. The connector 5 is installed on the outer periphery of the rotating shaft 1, and the inverted U-shaped frame 8 is installed below the support plate 9. A rotating shaft 2 passes through the inverted U-shaped frame 8. An L-shaped frame 4 is installed on the side of the connector 5, and a U-shaped frame 6 is installed above the L-shaped frame 4. A rotating shaft 3 passes through the U-shaped frame 6, and a connecting rod 7 is installed between the outer periphery of the rotating shaft 2 and the outer periphery of the rotating shaft 3.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the drive mechanism includes an adsorption component 19 and a cylinder 18. The cylinder 18 is mounted on the side of the support plate 9 via a support platform. The adsorption component 19 is detachably connected to the piston rod end of the cylinder 18, and the adsorption component 19 mates with the groove.

[0030] like Figure 1 , Figure 2 and Figure 4As shown, the drilling mechanism includes a guide rail 13 and a servo motor 17. The guide rail 13 is mounted on the output end of the drive motor 12, and the servo motor 17 is mounted on the end of the guide rail 13. A ball screw is detachably connected to the output end of the servo motor 17, and a slider 14 is fitted on the ball screw. The slider 14 is slidably connected to the guide rail 13. A drive motor 15 is mounted on the slider 14, and a drill bit 16 is detachably connected to the output end of the drive motor 15.

[0031] In this invention, the drive motor 12 is externally connected to a controller, and the lifting mechanism, drilling mechanism and drive mechanism are all communicatively connected to the controller.

[0032] In this invention, the ends of the first and second slides near the adsorption member 19 are open.

[0033] In this invention, the adsorption element 19 is an existing vacuum adsorption mechanism or electromagnetic adsorption mechanism.

[0034] In this invention, the length of guide rail 13 is equal to half of slide groove 1 or slide groove 2.

[0035] In this utility model, drive motor 2 12, drive motor 11, cylinder 18, servo motor 17, drive motor 3 15 and adsorption component 19 are all connected to the controller for communication.

[0036] The working principle of this utility model is as follows: First, the operator moves the device to the position where drilling is required, and then turns on the drive motor 11. The output end of the drive motor 11 drives the worm 21 to rotate. Since the worm 21 meshes with the worm wheel 20, the rotation of the worm 21 drives the worm wheel 20 to rotate, causing the rotating shaft 1, which passes between the two connecting plates 3, to rotate. The connecting piece 5 installed on the outer periphery of the rotating shaft 1 rotates synchronously with the rotating shaft 1. The L-shaped frame 4 on the side of the connecting piece 5 drives the U-shaped frame 6 to move, and the rotating shaft 3 inside the U-shaped frame 6 rotates accordingly. The rotating shaft 2 inside the inverted U-shaped frame 8 is connected to the rotating shaft 3 through the connecting rod 7, forming a crank-connecting rod mechanism. When the rotating shaft 1 rotates, the rotating shaft 3 makes a circular motion, which drives the rotating shaft 2 to move up and down inside the inverted U-shaped frame 8 through the connecting rod 7, thereby causing the inverted U-shaped frame 8 to drive the support plate 9 to rise and fall. After the support plate 9 moves to the appropriate position, the drive motor 11 is turned off.

[0037] The cylinder 18, mounted on the side support platform of the support plate 9, is activated. The suction member 19 at the end of the piston rod of the cylinder 18 engages with the groove 1 at the corresponding position of the sliding member 10. The suction member 19 adheres to the groove 1, and the cylinder 18 pushes the suction member 19, causing the sliding member 10 to slide in the slide groove 1, thereby achieving horizontal position adjustment (along the slide groove 1 direction). When it is necessary to switch to the slide groove 2 direction, the suction member 19 separates from the current groove 1, and the cylinder 18 in the other direction is activated, so that the suction member 19 engages with the groove 1 at the corresponding position of the sliding member 10, pushing the sliding member 10 to slide in the slide groove 2, thereby achieving position adjustment in two mutually perpendicular directions, ensuring that the drilling mechanism can accurately move to the drilling position required for blasting in mining operations.

[0038] After adjusting the sliding member 10 to a suitable position within the slide groove one or slide groove two, the corresponding cylinder one 18 is closed, and the adsorption member 19 continues to adsorb the sliding member 10. The drive motor two 12 is then started, and the guide rail one 13 rotates with the drive motor two 12 to adjust the drilling angle. The drive motor two 12 is then closed, and the servo motor one 17 and the drive motor three 15 are then started. The ball screw at the output end of the servo motor one 17 rotates, and the slider one 14, which cooperates with the ball screw, slides on the guide rail one 13, realizing the feed movement of the drill bit 16 in the drilling depth direction. The drive motor three 15 drives the drill bit 16 to rotate at high speed to perform drilling operations on the mine rock.

[0039] In this invention, the controller is capable of automatic control.

How to specifically implement braking control and the braking control method are not the technical problems to be solved or the objects of protection of this utility model. Furthermore, the communication methods between the devices all adopt existing communication methods, which are not the focus of this application.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
