Description

Technical Field

[0001] The present invention relates to the technical field of a rock drilling device, and in particular to a rock drilling device with a folding boom structure used in a rock drilling trolley. Background Art

[0002] The rock drilling device with a folding boom structure is a device designed for narrow and complex terrain. Its feature is that the boom can be folded for easy transportation and operation. The device drives the boom to extend and fold through a hydraulic system and is equipped with high-precision rock drilling tools. It can perform efficient and accurate rock drilling operations at various angles and positions. It is widely used in mining, tunnel construction and other fields.

[0003] When performing right-angle turning drilling operations, there are usually rock masses that need to be drilled and blasted. These protruding rock masses not only hinder the normal turning path of the drill rig, making it prone to collision, but also significantly increase the complexity and difficulty of the operation, resulting in reduced construction efficiency and increased operational risks.

[0004] Based on the above situation, the present invention proposes a rock drilling device with a folding boom structure used in a rock drilling trolley. Summary of the invention

[0005] In order to overcome the disadvantage that a rock drilling device is prone to hit a protruding rock mass when turning, the present invention provides a rock drilling device with a folding boom structure used in a rock drilling trolley.

[0006] The cam is connected to the guide frame by a camshaft, and the camshaft is connected to the guide frame by a camshaft, and the camshaft is connected to the guide frame by a camshaft.

[0007] Furthermore, it also includes a connecting plate, which is fixedly connected to the card frame, and the connecting plate has a sliding groove. The support frame is slidably connected to a guide frame, and the guide frame is slidably connected to the sliding groove of the connecting plate. The connecting plate is extruded and fitted with the guide frame, and the support frame is slidably connected to a cartridge symmetrically distributed along the support frame, and the cartridge is extruded and fitted with the guide frame, and the cartridge is inserted into the corresponding card hole.

[0008] Furthermore, one side of the guide frame is provided with upper inclined grooves symmetrically distributed along the guide frame, and the cartridge is slidably connected to the upper inclined grooves adjacent to the guide frame.

[0009] Furthermore, a lower inclined groove is formed on the other side of the guide frame, and the connecting plate is slidably connected to the lower inclined groove of the guide frame.

[0010] Furthermore, it also includes a tension spring corresponding to the rotating rod, and both ends of the tension spring are fixedly connected to the adjacent rotating rod and the motor respectively. The clamping frame and the clamping cylinder are both fixedly connected with relative fixed blocks. A pulling frame is slidably connected between the two fixed blocks of the clamping frame and between the two fixed blocks of the clamping cylinders, and the pulling frame is rotationally connected to the adjacent rotating rod.

[0011] Furthermore, it also includes a sealing plate symmetrically distributed along the rack, the sealing plate is slidably connected to the support frame, the sealing plate is squeezed and matched with the adjacent rack, the sealing plate is used to scrape out the rock ash in the rack gap, and a spring is fixed between the sealing plate and the support frame.

[0012] Furthermore, it also includes a material guide plate corresponding to the sealed plate, and the material guide plate is fixedly connected to the outer side of the corresponding sealed plate.

[0013] Furthermore, it also includes a telescopic baffle symmetrically distributed along the rack, the telescopic side of the telescopic baffle is fixedly connected to the support frame, and the fixed side of the telescopic baffle is fixedly connected to the guide frame.

[0014] The beneficial effect of the present invention is that during the process of controlling the rotation of the support frame, if the guide frame rotates directly, it will collide with the rock mass. The movement of the guide frame is controlled by a motor to achieve the effect of adjusting the turning radius of the guide frame, so that when the telescopic arm encounters a rock mass during rotation, it can adaptively adjust the length to avoid it and avoid collision, so that it can continue to rotate further, and after the adjustment, the guide frame is locked to prevent the output shaft from rotating arbitrarily after the motor is turned off, causing the guide frame to move arbitrarily.

[0015] The present invention fixes the guide frame from the front and rear sides respectively through the clamping frame and the clamping cylinder, thereby avoiding unbalanced fixation of the guide frame on one side and improving stability during rock drilling.

[0016] The present invention pulls the rotating rod on the pulling frame to slide relative to the output shaft of the motor, so that the rotating rod and the adjacent gear are no longer engaged. Therefore, after the guide frame is fixed, even if the motor is started by mistake, the output shaft of the motor only drives the rotating rod to rotate idly, and does not drive the gear to rotate, thereby avoiding the phenomenon of tooth knocking between the rack and the gear due to accidental contact with the motor during rock drilling.

[0017] When the rack moves to adjust the guide frame, the sealed plate is used to scrape out the rock ash in the rack gap, and the scraped dust will slide forward and downward and rearward along the bottom of the guide plate to the ground, thereby achieving the effect of automatically cleaning the rack gap and avoiding the rack gap being blocked and affecting its meshing action with the gear.

[0018] The present invention utilizes the telescopic baffles on the left and right sides to adaptively telescope as the support frame moves left and right, so that only the clamping holes where the support frame is located are opened, and the clamping holes at other locations are closed by the telescopic baffles in real time to prevent the clamping holes from being blocked by rock ash.

DETAILED DESCRIPTION

[0030] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1: A rock drilling device with a folding boom structure used in a rock drilling trolley, such as Figure 1-Figure 4 As shown, it includes a telescopic arm frame 1, the telescopic end of the telescopic arm frame 1 is rotatably connected to a support frame 2, the support frame 2 is slidably connected to a guide frame 3 in the left and right directions, the lower side of the guide frame 3 is fixedly connected to a rack 301 symmetrically distributed along the front and back of the guide frame 3, the upper side of the guide frame 3 is slidably connected to a drilling arm frame 4 in the left and right directions, the middle of the support frame 2 is fixedly connected to a motor 5 symmetrically distributed along the front and back of the support frame 2, the output shaft of the motor 5 is splined to a rotating rod 6, the output shaft of the motor 5 is rotatably connected to a gear 7, the rotating rod 6 is engaged with an adjacent gear 7, so that the motor 5 drives the rotating rod 6 to rotate synchronously, the rotating rod 6 drives the gear 7 to rotate when engaged, and the rotating rod 6 rotates idly when not engaged, and the gear 7 is meshed with the adjacent rack 301, an electric push rod 8 is fixedly connected to the front side of the support frame 2, the telescopic end of the electric push rod 8 is fixedly connected to a clamping frame 9, the clamping frame 9 is slidably connected to the support frame 2, the guide frame 3 is provided with clamping holes 901 evenly arranged in the transverse direction, and the clamping frame 9 moves backward and is inserted into the corresponding clamping hole 901.

[0032] When using the device for rock drilling, the telescopic boom 1 is controlled to be extended and retracted, and the support frame 2 is controlled to rotate and swing, and then the drilling boom 4 is controlled to slide and extend along the guide frame 3 until it contacts the rock mass, and then rock drilling can begin. In the process of controlling the rotation of the support frame 2, if the guide frame 3 directly rotates and hits the rock mass, the motor 5 is started, and the output shaft of the motor 5 drives the rotating rod 6 to rotate, thereby driving the gear 7 to rotate, and then driving the rack 301 to move to the side close to the telescopic boom 1, and then driving the guide frame 3 to move to the side close to the telescopic boom 1, so as to adjust the turning radius of the guide frame 3 The effect is that the telescopic arm 1 can adaptively adjust its length to avoid the rock when it encounters the rock during rotation, so as to avoid collision, so that it can continue to rotate further. After adjusting the avoidance distance, the motor 5 is turned off, and the electric push rod 8 is controlled to extend to drive the bracket 9 to move backward and insert it into the corresponding bracket hole 901 of the guide frame 3, so as to lock the guide frame 3 to prevent the output shaft from rotating arbitrarily after the motor 5 is turned off, causing the guide frame 3 to move arbitrarily. When the turning radius needs to be adjusted again, the electric push rod 8 is controlled to shorten, so that the bracket 9 moves forward and pulls out of the bracket hole 901.

[0033] like Figure 5 and Figure 6 As shown, it also includes a connecting plate 10, which is fixedly connected to the bracket 9, and a sliding groove is opened at the rear of the connecting plate 10. The rear side of the support frame 2 is slidably connected with a guide frame 11 along the up-down direction, and the guide frame 11 is slidably connected to the sliding groove of the connecting plate 10. The upper side of the guide frame 11 is provided with an upper inclined groove symmetrically distributed along the left and right of the guide frame 11, and the lower side of the guide frame 11 is provided with a lower inclined groove. The rear part of the connecting plate 10 is slidably connected to the lower inclined groove of the guide frame 11, so that the connecting plate 10 moves backward and pushes the guide frame 11 to move upward. The middle of the support frame 2 is slidably connected with a cartridge 12 symmetrically distributed along the left and right of the support frame 2 along the front-to-back direction, and the cartridge 12 is slidably connected to the upper inclined groove adjacent to the guide frame 11, and the cartridge 12 moves forward and is inserted into the corresponding card hole 901.

[0034] When the bracket 9 moves backward and is inserted into the clamping hole 901, the bracket 9 simultaneously drives the connecting plate 10 to move backward, the connecting plate 10 squeezes the guide frame 11 to move upward, and the guide frame 11 squeezes the cartridge 12 to move forward and insert into the corresponding clamping hole 901. In this way, the bracket 9 and the cartridge 12 respectively fix the guide frame 3 from the front and back sides, avoiding the imbalance of unilateral fixation of the guide frame 3 and improving the stability during rock drilling. When the bracket 9 moves forward and is pulled out of the clamping hole 901, the bracket 9 simultaneously drives the connecting plate 10 to move forward, the connecting plate 10 drives the guide frame 11 to move downward, and the guide frame 11 drives the cartridge 12 to move backward and pull out of the clamping hole 901.

[0035] Embodiment 2: Based on embodiment 1, Figure 7 and Figure 8 As shown, it also includes a tension spring 15 corresponding to the rotating rod 6, and the two ends of the tension spring 15 are respectively fixedly connected to the adjacent rotating rod 6 and the motor 5. The bracket 9 and the clamping cylinder 12 are both fixedly connected with relative fixed blocks 13. A pull frame 14 is slidably connected between the two fixed blocks 13 of the bracket 9 and between the fixed blocks 13 of the two clamping cylinders 12. The pull frame 14 is rotationally connected to the adjacent rotating rod 6.

[0036] When the bracket 9 and the cartridge 12 are inserted into the clamping hole 901, the bracket 9 and the cartridge 12 simultaneously drive the fixed block 13 thereon to move in the same direction. The fixed block 13 first slides relative to the adjacent pull frame 14, and then drives the pull frame 14 to move together, so that the pull frame 14 pulls the rotating rod 6 thereon to slide relative to the output shaft of the motor 5, and the tension spring 15 is stretched, so that the rotating rod 6 and the adjacent gear 7 are no longer engaged. In this way, after the guide frame 3 is fixed, even if the motor 5 is started by mistake, the output shaft of the motor 5 will only drive the rotating rod 6 to idle, and will not drive the gear 7 to rotate, so as to avoid the tooth-clamping phenomenon between the rack 301 and the gear 7 due to accidental contact with the motor 5 during rock drilling. When the bracket 9 and the cartridge 12 are pulled out of the clamping hole 901, the bracket 9 and the cartridge 12 simultaneously drive the fixed block 13 thereon to move in the same direction and reset. The tension spring 15 resets and drives the rotating rod 6 to slide in the opposite direction relative to the output shaft of the motor 5, thereby driving the pull frame 14 to move in the opposite direction and reset.

[0037] Embodiment 3: Based on embodiment 2, Fig. 9 As shown, it also includes a closed plate 16 symmetrically distributed along the rack 301. The closed plate 16 is slidably connected to the support frame 2. The lower part of the closed plate 16 is squeezed and matched with the adjacent rack 301. The closed plate 16 is used to scrape out the rock ash in the gap of the rack 301. A spring 17 is fixed between the closed plate 16 and the support frame 2. A guide plate 18 is fixed to the outer side of the closed plate 16. The bottom of the guide plate 18 is inclined outward and downward, and is used to guide the scraped rock ash to the ground.

[0038] The dust generated when drilling rocks will fall into the gap of the rack 301. When the rack 301 moves to the left or right, it will squeeze the sealing plates 16 on the left and right sides to move upward intermittently, and the spring 17 will be intermittently compressed and reset. During this process, the sealing plates 16 will scrape the rock ash in the gap of the rack 301, and the scraped dust will slide forward and downward and backward along the bottom of the guide plate 18 to the ground, thereby achieving the effect of automatically cleaning the gap of the rack 301 and avoiding the gap of the rack 301 from being blocked and affecting its meshing action with the gear 7.

[0039] like Fig.10 As shown, it also includes a telescopic baffle 19 symmetrically distributed along the rack 301 , the telescopic side of the telescopic baffle 19 is fixedly connected to the support frame 2 , and the fixed side of the telescopic baffle 19 is fixedly connected to the guide frame 3 .

[0040] The telescopic baffles 19 on the left and right sides are adaptively telescopic as the support frame 2 moves left and right, so that only the clamping holes 901 where the support frame 2 is located are opened, and the clamping holes 901 at other locations are closed by the telescopic baffles 19 in real time to prevent the clamping holes 901 from being blocked by rock ash.

[0041] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principle and spirit of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the present invention, but the scope of protection is limited by the content of the claims.
