Description

Technical Field

[0001] This utility model belongs to the field of drilling equipment technology, and specifically relates to a track-type rock drilling device. Background Technology

[0002] A rock drill is a device used to drill holes in rock formations so that explosives or splitting arms can be inserted to break up the rock.

[0003] Currently, rock drills are commonly used to open blast holes during tunnel excavation. In order to improve the efficiency of blast hole opening, a multi-head rock drill has emerged in the existing technology. This multi-head rock drill consists of multiple rock drills fixedly installed on a ring frame. When in use, multiple rock drills can be used to open blast holes arranged circumferentially around the tunnel face, thereby improving the efficiency of blast hole opening.

[0004] However, the position of the rock drill in this multi-head rock drilling rig cannot be changed; blast holes can only be opened at fixed locations. If blast holes need to be opened at locations other than those corresponding to the rock drill, the rock drill must be erected on the support frame at the desired blast hole position, and manual support is required for the opening. This process is labor-intensive and inefficient. Therefore, inventing a rock drilling device that can adjust the position of the rock drill is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model provides a track-type rock drilling device to solve the technical problem in the prior art where, when a multi-head rock drilling rig needs to open a blast hole at a location that does not correspond to the rock drilling rig, it is necessary to re-erect the rock drilling rig and manually support the opening of the blast hole, which leads to a reduction in construction efficiency.

[0006] To solve the above problems, this utility model is achieved through the following technical solution:

[0007] A track-type rock drilling device includes a drilling device, a toothed ring, and a circular slide rail;

[0008] The radius of the gear ring is equal to the radius of the slide rail, and the gear ring and the slide rail are coaxially connected to form a circular track;

Both the drive motor and the drilling section are mounted on the sliding block. The actuating end of the drive motor is equipped with a drive gear that meshes with a gear ring.

[0010] To better realize this utility model, further optimizations are made to the above structure. There are two annular tracks, which are coaxial and spaced apart. The two annular tracks are connected and fixed by a support rod to form a cylindrical frame.

[0011] The two ends of the sliding block are respectively slidably mounted on the slide rails in two annular tracks.

[0012] To better realize this utility model, further optimization is made to the above structure. The track-type rock drilling device also includes a support frame, on which two sets of support parts are provided. The two sets of support parts are respectively located on the two end faces of the support frame.

[0013] The annular track is mounted on the support frame and is coaxial with the support frame.

[0014] To better realize this utility model, further optimizations are made to the above structure, wherein the annular track includes a top arc segment, a bottom arc segment, and two sets of side arc segments;

The movement direction of the second telescopic rod is perpendicular to the plane of the base plate, and the telescopic end of the second telescopic rod is connected to the fixed end of the lower track. A slider that slides along the width direction of the support frame is provided on the sliding seat, and a third telescopic rod is hinged on the slider. The moving end of the third telescopic rod is connected to the movable end of the lower track; the two sets of side arc segments are located on both sides of the support frame;

[0017] The bottom arc segment is set below the support frame by a swing mechanism, which can drive the bottom arc segment to swing between two circular tracks;

[0018] When the circular track is in the unfolded state, the top arc segment, one set of side arc segments, the bottom arc segment, and the other set of side arc segments are connected end to end in sequence.

[0019] To better realize this utility model, further optimizations are made to the above structure, wherein the swing mechanism includes a swing motor and a swing rod;

[0020] The swing motor is located on the lower end of the base plate. One end of the swing rod is connected to the actuating end of the swing motor. The length direction of the swing rod is perpendicular to the swing axis of the swing motor. The end of the swing rod away from the swing motor is connected to the bottom arc segment.

[0021] To better realize this utility model, further optimization is made to the above structure. The swing mechanism has two sets, and the actuating ends of the two sets of swing mechanisms are respectively connected to the two ends of the bottom arc segment.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] In the embodiments of this application, such as Figures 1 to 6 As shown, the track-type rock drilling device includes a drilling device 2, a toothed ring, and a circular slide rail;

[0043] The radius of the gear ring is equal to the radius of the slide rail. The gear ring and the slide rail are coaxially connected to form a circular track 1. (See [reference]) Figure 3 ;

[0044] The drilling device 2 includes a sliding block 21, a drive motor, and a drilling part 22. The sliding block 21 is slidably mounted on the slide rail. The drive motor and the drilling part 22 are both mounted on the sliding block 21. The driving end of the drive motor is provided with a drive gear that meshes with the gear ring so that the drive motor can drive the sliding block 21 to move along the annular track 1 when it is in motion.

[0045] When it is necessary to open a blast hole, the operator can control the drive motor to drive the drive gear, so that the drilling device 2 can move along the slide rail until it stops at the position where the blast hole needs to be opened; then the drilling part 22 in the drilling device 2 can be controlled to open the blast hole.

[0046] Furthermore, while the blast hole at this location is being opened, the workers can continue to control the drive motor to move the drilling device 2 to the next location where a blast hole needs to be opened to continue the blast hole opening work. The entire work process only requires the workers to control the movement of the drilling device 2 and the operation of the drilling part 22, so that the blast hole can be opened at any location along the circumference of the tunnel face easily and quickly, without the need to rebuild the drilling device 2 or manually support the drilling device 2, thus reducing labor intensity.

[0047] Preferably, the number of the above-mentioned drilling devices 2 is multiple, see [reference]. Figure 1 Multiple drilling devices 2 can work together to open blast holes, thereby further improving the working efficiency of the rail-mounted rock drilling device.

[0048] In some embodiments, the drilling device 2 described above further includes a telescopic mechanism, see [link to documentation]. Figure 6 ;in,

[0049] The telescopic mechanism is mounted on the sliding block 21, and the direction of movement of the telescopic mechanism is parallel to the axis of the annular track 1. The aforementioned drilling part 22 is mounted on the moving end of the telescopic mechanism.

[0050] When there is a large gap between the annular track 1 and the working face, causing the end of the drilling part 22 (working end) to be unable to contact the working face for hole opening, the operator can control the telescopic mechanism to send the drilling part 22 toward the working face so that the end of the drilling part 22 can contact the working face and open the blast hole.

[0051] Specifically, the telescopic mechanism includes a telescopic cylinder and a sliding seat. The sliding seat is slidably mounted on the sliding block 21 along the length of the sliding block 21. The telescopic cylinder is mounted on the sliding block 21, and the actuating end of the telescopic cylinder is connected to the sliding seat. The aforementioned drilling part 22 is mounted on the sliding seat. By controlling the extension or retraction of the telescopic cylinder, the distance between the drilling part 22 and the working face can be adjusted, making the use of the track-type rock drilling device more convenient.

[0052] In some embodiments, there are two annular tracks 1, which are coaxial and spaced apart. The two annular tracks 1 are connected and fixed by support rods 3 to form a cylindrical frame. See [link to documentation]. Figure 1 ;

[0053] The two ends of the sliding block 21 are respectively slidably set on the slide rails in the two annular tracks 1;

[0054] During the drilling process of the borehole section 22, as the end of the borehole section 22 contacts the working face and moves into the depth of the working face, the working face will exert a reaction force on the borehole section 22. The two annular tracks 1 can provide good support and stress relief for the borehole section 22 to ensure the stability of the borehole section 22 during operation.

[0055] In some embodiments, the track-type rock drilling device further includes a support frame 4, on which two sets of support parts are provided. In this embodiment, there are two support frames 4, and the two sets of support parts are respectively arranged on the opposite sides of the two support frames 4. Each set of support parts includes two telescopic legs 41, and the two telescopic legs 41 are respectively located on both sides of the support frame 4.

[0056] The annular track 1 is mounted on the support frame 4, and the annular track 1 is coaxial with the support frame 4.

[0057] During the drilling process, the track-mounted rock drilling device is supported in the tunnel by two sets of support parts to fix the position of the track-mounted rock drilling device and support the drilling device 2, so that the drilling part 22 is more stable when drilling the blast hole.

[0058] In some embodiments, the annular track 1 includes a top arc segment 11, a bottom arc segment 12, and two sets of side arc segments 13. See also Figure 3 and Figure 4 ;

[0059] The top arc segment 11 is mounted above the support frame 4 via a support rod 431;

[0060] The side arc segment 13 includes an upper track and a lower track; the fixed end of the upper track is hinged to the end of the top arc segment 11, and the movable end of the upper track is connected to the support rod 431 through the first telescopic rod 432; a base plate 42 is provided on the lower end surface of the support frame 4, the plane of the base plate 42 is parallel to the horizontal plane, and a sliding seat 435 and a second telescopic rod 433 are respectively provided on the upper end surface and the lower end surface of the base plate 42. The movement direction of the second telescopic rod 433 is perpendicular to the plane of the base plate 42, and the telescopic end of the second telescopic rod 433 is connected to the fixed end of the lower track. A slider that slides along the width direction of the support frame 4 is provided on the sliding seat 435, and a third telescopic rod 434 is hinged on the slider. The moving end of the third telescopic rod 434 is connected to the movable end of the lower track; the two sets of side arc segments 13 are located on both sides of the support frame 4;

[0061] The bottom arc segment 12 is set below the support frame 4 by a swing mechanism 5, which can drive the bottom arc segment 12 to swing between the two annular tracks 1.

[0062] When the circular track 1 is in the deployed state, see Figure 1 and Figure 3 The top arc segment 11, one set of side arc segments 13, the bottom arc segment 12, and another set of side arc segments 13 are connected end to end in sequence.

[0063] When it is necessary to open blast holes, the workers can adjust the positions of the top arc segment 11, the bottom arc segment 12, and the two sets of side arc segments 13 by controlling the first telescopic rod 432, the second telescopic rod 433, the third telescopic rod 434, and the swing mechanism 5. This allows the top arc segment 11, one set of side arc segments 13, the bottom arc segment 12, and the other set of side arc segments 13 to be connected end to end in sequence, thus putting the circular track 1 in the unfolded state. See [link / reference]. Figure 3 The aforementioned drilling device 2 can then move along the annular track 1 to the corresponding position to perform the drilling work.

[0064] When the track-type rock drilling device needs to be moved, the operator can adjust the positions of the top arc segment 11, bottom arc segment 12, and two sets of side arc segments 13 by controlling the first telescopic rod 432, the second telescopic rod 433, the third telescopic rod 434, and the swing mechanism 5. This causes the top arc segment 11, bottom arc segment 12, and two sets of side arc segments 13 to retract towards the support frame 4, thus putting the circular track 1 in a retracted state. See [link / reference] Figure 2 and Figure 4 This allows the track-type rock drilling device to be moved along the tunnel excavation direction, while the retracted circular track 1 can prevent the circular track 1 from hitting the tunnel wall during the journey.

[0065] Of course, the structure of the circular track 1 can also be deformed according to the cross-sectional shape of the tunnel. For example, if the cross-section of the tunnel is circular, the circular track 1 needs to be in the unfolded state when drilling. The drilling device 2 can then stop at any position (circumferential direction) along the circular track 1 in the circular tunnel and carry out drilling.

[0066] If the cross-sectional shape of the tunnel is semi-circular, during drilling, the top arc segment 11 and the side arc segment 13 in the circular track 1 need to be connected to form a semi-circular track. The drilling device 2 can then stop at any position (circumferential direction) in the semi-circular tunnel along the semi-circular track and carry out drilling.

[0067] It should be noted that when the circular track 1 changes from the unfolded state to the retracted state, the drilling device 2 located on the circular track 1 must be in any one of the top arc segment 11, bottom arc segment 12, upper track and lower track, and cannot be located at the junction of the top arc segment 11, bottom arc segment 12, upper track and lower track.

[0068] In actual use, the track-type rock drilling device can be slidably mounted on the needle beam; specifically, the support frame 4 is a ring frame structure, and the support frame 4 is sleeved on the needle beam so that the track-type rock drilling device can slide along the length of the needle beam.

[0069] During use, the needle beam is placed in the tunnel, and the length direction of the needle beam is aligned with the tunnel excavation direction. The track-type rock drilling device can then slide along the length direction of the needle beam, allowing it to quickly move to the working face.

[0070] In some embodiments, the swing mechanism 5 described above includes a swing motor 51 and a swing rod 52, see [link / reference] Figure 5 ;

[0071] The swing motor 51 is mounted on the lower end face of the base plate 42. The swing axis of the swing motor 51 is parallel to the width direction of the support frame 4. One end of the swing rod 52 is connected to the actuating end of the swing motor 51, and the length direction of the swing rod 52 is perpendicular to the swing axis of the swing motor 51. The end of the swing rod 52 away from the swing motor 51 is connected to the bottom arc segment 12. Preferably, there are two sets of swing mechanisms 5, and the actuating ends of the two sets of swing mechanisms 5 are respectively connected to the two ends of the bottom arc segment 12 to make the bottom arc segment 12 more stable when swinging.

[0072] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
