Description

Technical Field

[0001] The invention relates to the technical field of dam reinforcement drilling, in particular to a crawler-type slope cone drilling rig. Background Art

[0002] With the development of economy, in order to develop and utilize river hydropower resources, it is necessary to take engineering measures on rivers or lakes. At present, most of the embankment reinforcement projects of rivers and lakes in my country have problems such as insufficient protection standards and partial collapse of revetments along rivers and lakes. Therefore, embankment survey and flood control embankment reinforcement are needed in river and lake construction. In the existing technology, drilling holes are usually formed by artificial drilling, and grouting is performed in the holes to form a reinforcement structure of the embankment slope protection, which has the problems of slow construction speed and extremely low efficiency.

[0003] The Chinese patent with the authorization announcement number CN101649722A proposes a drilling machine for use in drilling and rock drilling operations, including a drilling machine platform and a power device, the drilling machine platform includes a light circular crawler for transporting the drilling machine, a drilling guide arranged upright on the light circular crawler to guide the drilling head, a drilling hydraulic motor connected to the drilling guide to generate the rotational force of the drill bit, and a transport unit for controlling the position of the drilling guide and the drilling hydraulic motor, and the power device is detachably connected to the drilling machine platform to provide hydraulic power to the drilling machine platform through a hydraulic hose. In actual application, the drill bit is aligned with the position to be drilled, and the drilling hydraulic motor drives the drill bit to rotate and drill into the dam to achieve the purpose of automatic drilling.

[0004] The above-mentioned prior art solutions have the following defects: since the dam has a certain slope, the drilling rig platform will be in an inclined state when the light annular crawler is on the dam, so that the drill rod is inclined relative to the vertical direction. Therefore, the drill rod drills obliquely during the drilling process, and the force is uneven, which makes it difficult for the drill bit to drill, and the drilling efficiency is low. The obliquely extended drilling holes may even fail. Summary of the invention

[0005] In view of the shortcomings of the prior art, one of the objects of the present invention is to provide a crawler type slope cone drill rig whose operating platform can be automatically leveled according to the slope of the dam, keeping the operating platform of the cone drill rig in a horizontal state and the cone drill rod in a vertical working state.

[0006] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0007] A crawler type slope cone drilling rig comprises a crawler chassis, a rotating platform is swingably arranged on the crawler chassis, a control box is fixed on the side of the rotating platform away from the crawler chassis, and a drill rod for drilling a drilling hole is lifted and arranged in the control box.

[0008] By adopting the above technical solution, when the crawler chassis is on the dam, the crawler chassis, the rotating platform, the drilling guide tube and the drill rod are all inclined relative to the slope of the dam. During the drilling process, the swing of the rotating platform drives the control box and the drill rod to swing. When the rotating platform swings to a horizontal state, the drill rod swings to a vertical state, and the drill rod is lowered to drill the dam in a vertical direction. The drilled grouting hole extends in the vertical direction. The present invention swings the drill rod to a vertical state by swinging the control box and the rotating platform to achieve vertical drilling. The drilling process is smoother, and the drilled grouting hole is more stable, which effectively solves the problem of drilling difficulties caused by oblique drilling in the prior art and has high work efficiency.

[0009] In a preferred example, the present invention can be further configured as follows: a longitudinal center axis is fixed to the crawler chassis directly below the rotating platform, and a peripheral side of the longitudinal center axis is fixedly connected to a side of the rotating platform close to the crawler chassis.

[0010] By adopting the above technical solution, the rotating platform is supported by the longitudinal central axis, and the rotating platform swings around the longitudinal central axis.

[0011] In a preferred example, the present invention can be further configured as follows: the crawler chassis is fixedly connected with semicircular plates at both ends of the longitudinal center axis, and the longitudinal center axis and the semicircular plates are coaxially fixedly connected via an axle pin.

[0012] By adopting the above technical solution, the semicircular plate is used to realize the fixed connection between the longitudinal center axis and the crawler chassis, and the pin shaft is used to realize the rotational connection between the longitudinal center axis and the semicircular plate.

[0013] In a preferred example, the present invention can be further configured as follows: the crawler chassis is hingedly connected to one side of the rotating platform with a control cylinder for driving the control box to swing, and the control cylinder enables the rotating platform to swing in both directions.

[0014] By adopting the above technical solution, the reciprocating motion of the piston rod of the oil cylinder is used to drive the control box to swing, thereby driving the rotating platform and the drill rod to swing.

[0015] In a preferred example, the present invention can be further configured as follows: a swing arm fixedly connected to the control box is swingably arranged on the rotating platform, and a servo motor for driving the swing arm to swing in both directions is also fixed on the rotating platform.

[0016] By adopting the above technical solution, the servo motor drives the swing rod to swing, thereby driving the rotating platform and the drill rod to swing.

[0017] In a preferred example, the present invention can be further configured as follows: a support frame is fixedly mounted on the rotating platform, the swing arm is fixedly connected to a connecting rod, and the support frame is provided with a connecting groove that is slidingly adapted to the connecting rod along the swing path of the swing arm.

[0018] By adopting the above technical solution, during the swing of the swing arm, the swing range of the swing arm is limited by the sliding adaptation of the connecting rod connecting groove, and the swing of the swing arm is made more stable.

[0019] In a preferred example, the present invention can be further configured as follows: a drilling guide tube for guiding the drilling direction of the drill rod is fixed on the control box.

[0020] By adopting the above technical solution, the drilling direction of the drill rod is guided by the drilling guide tube, thereby ensuring the stability of the drilling work and reducing the deviation of the drilling.

[0021] In a preferred example, the present invention can be further configured as follows: the drilling guide tube is fixed to a side of the control box away from the crawler chassis, and a lifting mechanism for driving the drill rod to be lifted and lowered is fixed in the control box.

[0022] By adopting the above technical solution, the lifting mechanism is used to drive the drill rod to lift and lower along the guide direction of the drilling guide tube, and the drilling guide tube is used to limit the displacement range of the drill rod to maintain the stability of the drill rod during drilling.

[0023] In a preferred example, the present invention can be further configured as follows: the lifting mechanism includes two drive shafts, two drive wheels, and a drive motor; the two drive shafts are arranged inside the control box on both sides of the drill rod for relative rotation; the circumference of the drive shaft is coaxially fixedly connected to the drive wheel abutting against the circumference of the drill rod; and a drive motor for driving one of the drive shafts to rotate is fixed outside the control box.

[0024] By adopting the above technical solution, the driving motor drives one of the driving shafts to rotate, which drives one of the driving wheels to rotate. The friction between the two driving wheels is used to make the two driving wheels rotate in relative directions. At the same time, the friction between the drill rod and the circumference of the two driving wheels is used to drive the drill rod to be lifted and lowered.

[0025] In a preferred example, the present invention can be further configured as follows: a groove is provided on the circumference of the driving wheel, the drill rod is located in a space formed by two grooves, and the circumference of the drill rod abuts against the inner walls of the two grooves.

[0026] By adopting the above technical solution, the drill rod is inserted into the space formed by the two embedding grooves, and the two embedding grooves are used to limit the range of motion of the drill rod, which effectively reduces the deviation of the drill rod position, making the drill rod more stable during drilling and the drilling work smoother.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

[0028] 1. The swing of the rotating platform drives the control box, drilling guide tube and drill rod to swing. When the rotating platform swings to a horizontal state, the drill rod swings to a vertical state, so that the drill rod can drill in a vertical direction. The drilling process is smoother and the work efficiency is high. The grouting holes drilled are vertically extended, which is convenient for grouting work in the later stage.

[0029] 2. The reciprocating motion of the piston rod of the oil cylinder drives the control box to swing, which has a simple structure, stable swing, easy to implement, convenient for later repair, and effectively saves manufacturing and use costs;

[0030] 3. The servo motor drives the swing arm to swing, thereby driving the control box, rotating platform, drilling guide tube and drill rod to swing. The swing is more flexible and has a larger swing range, which can be applied to more environments. The swing range of the swing arm is limited by the sliding adaptation of the connecting rod connecting groove, and the swing of the swing arm is made more stable.

[0031] 4. The driving motor and two driving wheels are used to drive the drill rod to rise and fall. The driving method is simple, energy-saving and more environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0040] Reference Figure 1 , a crawler type slope cone drilling rig disclosed by the present invention, comprises a crawler chassis 1, a diesel engine is fixed at one end of the crawler chassis 1, an output drive wheel is arranged on the diesel engine, the drive wheel is respectively connected with a reducer and a hydraulic gear oil pump through a grooved V-belt, and the forward and backward walking and steering functions of the crawler chassis 1 are realized through the reducer and the joystick.

[0041] The crawler chassis 1 is provided with a rotating platform 2 at one end away from the diesel engine, and a swing groove is provided at the position where the rotating platform 2 is located to facilitate the swing of the rotating platform 2. Figure 2 A longitudinal center axis 7 is fixed to the crawler chassis 1 directly below the rotating platform 2. The axis of the longitudinal center axis 7 extends along the length direction of the crawler chassis 1. The circumference of the longitudinal center axis 7 is fixedly connected to the side of the rotating platform 2 close to the crawler chassis 1. The axis of the longitudinal center axis 7 coincides with the geometric center line of the rotating platform 2. Figure 1 and Figure 2 The crawler chassis 1 is fixedly connected with semicircular plates 8 at both ends of the longitudinal center axis 7. The axis of the semicircular plates 8 is coaxially arranged with the axis of the longitudinal center axis 7. The longitudinal center axis 7 and the semicircular plates 8 are coaxially fixedly connected by an axle pin. The longitudinal center axis 7 is used to support the rotating platform 2, and the rotating platform 2 swings around the longitudinal center axis 7. The semicircular plates 8 are used to realize the fixed connection between the longitudinal center axis 7 and the crawler chassis 1, and the longitudinal center axis 7 and the semicircular plates 8 are rotatably connected by a pin.

[0042] Reference Figure 1 The crawler chassis 1 is hingedly connected to a control cylinder 6 on one side of the rotating platform 2. The piston rod of the control cylinder 6 extends along the width direction of the crawler chassis 1 and extends toward one side of the control box 3 (see below) and is hingedly connected to the control box 3. The telescopic movement of the piston rod of the control cylinder 6 drives the control box 3 to swing, thereby realizing the bidirectional swing of the rotating platform 2.

[0043] A control box 3 is fixed on the side of the rotating platform 2 away from the crawler chassis 1. The control box 3 is in a rectangular shape and is hollow inside. A drilling guide tube 4 is fixed on the side of the control box 3 away from the crawler chassis 1. The drilling guide tube 4 is penetrated at both ends along the axial direction. Figure 2 A drill rod 5 for drilling a drilling hole is lifted and lowered in the drilling guide tube 4. The axis of the drill rod 5 coincides with the axis of the drilling guide tube 4. The end of the drill rod 5 close to the groove V-belt is conical. The drill rod 5 is used to drill grouting holes on the dam, and the drilling guide tube 4 is used to limit the displacement range of the drill rod 5 to keep the drill rod 5 stable during the drilling process.

[0044] Reference Figure 1 and Figure 2 A lifting mechanism for driving the drill rod 5 to rise and fall is fixed in the control box 3. The lifting mechanism includes two drive shafts 9, two drive wheels 10, and a drive motor 11. Figure 2 Two drive shafts 9 are arranged inside the control box 3 on both sides of the drill rod 5 for relative rotation. The axis of the drive shaft 9 is arranged orthogonally to the axis of the drilling guide tube 4. The circumference of the drive shaft 9 is coaxially fixedly connected to the drive wheel 10 that abuts against the circumference of the drill rod 5. Figure 1 A driving motor 11 is fixed to the outside of the control box 3 to drive one of the driving shafts 9 to rotate. The rotating shaft of the driving motor 11 is coaxially fixedly connected with the axis of the driving shaft 9. The driving motor 11 drives one of the driving shafts 9 to rotate, driving one of the driving wheels 10 to rotate. The friction between the two driving wheels 10 is used to make the two driving wheels 10 rotate in opposite directions. At the same time, the friction between the drill rod 5 and the peripheral sides of the two driving wheels 10 is used to drive the drill rod 5 to move up and down.

[0045] Reference Figure 2 The peripheral side of the driving wheel 10 is provided with an embedding groove 12, which is extended along the circumferential direction of the driving wheel 10. The drill rod 5 is located in the space formed by the two embedding grooves 12, and the peripheral side of the drill rod 5 abuts against the inner walls of the two embedding grooves 12. The drill rod 5 is inserted into the space formed by the two embedding grooves 12, and the two embedding grooves 12 are used to limit the range of movement of the drill rod 5, which effectively reduces the deviation of the position of the drill rod 5, making the drill rod 5 more stable during drilling and the drilling work smoother.

[0046] Reference Figure 1 The rotating platform 2 is provided with an interactive platform 13 extending from one end near the diesel engine, on which a seat 14 and a control panel 15 are fixed, and on which a switch for controlling the opening and closing of the operating cylinder and the driving motor 11 is fixed. The swing of the rotating platform 2 drives the interactive platform 13 to swing, so that it is more convenient for the staff to adjust the verticality of the drill rod 5, and the operating cylinder and the driving motor 11 are controlled through the interactive platform 13, so as to maximize the drilling stability and drilling effect of the drill rod 5.

[0047] Reference Figure 3 A support rod 16 for supporting the interactive platform 13 is fixed to one end of the crawler chassis 1 near the interactive platform 13, and the axis of the support rod 16 coincides with the axis of the longitudinal center axis 7. The interactive platform 13 is supported by the support rod 16, so that the interactive platform 13 is more stable during the swinging process.

[0048] The implementation principle and beneficial effects of this embodiment are as follows:

[0049] Reference Figure 4 and Figure 5 , the crawler chassis 1 moves to the designated position of the dam, controls the telescopic movement of the piston rod of the operating cylinder 6, drives the rotating platform 2, the control box 3, the drilling guide tube 4, and the drill rod 5 to swing, and the rotating platform 2 in an inclined state is swung to a horizontal state, and the drill rod 5 is swung to a vertical state, and the linkage of the driving motor 11, the driving shaft 9, and the two driving wheels 10 drives the drill rod 5 to descend in the vertical direction, and drills the dam, so that the drilled grouting hole extends in the vertical direction. The present invention swings the drill rod 5 to a vertical state by swinging the control box 3 and the rotating platform 2, realizes drilling in the vertical direction, and the drilling process is smoother, and the drilled grouting hole is more stable, which effectively solves the problem of drilling difficulties caused by oblique drilling in the prior art, and has high work efficiency.

[0050] Embodiment 2

[0051] A crawler-type slope cone drilling rig, which is different from the first embodiment in that:

[0052] A swing rod 17 fixedly connected to the outer wall of the control box 3 is swingably provided on the rotating platform 2. A servo motor 18 driving the swing rod 17 to swing in both directions is also fixed on the rotating platform 2. The rotating shaft of the servo motor 18 is fixedly connected to one end of the swing rod 17 through a bearing. A support frame 19 is fixedly provided on the rotating platform 2. A connecting rod 20 is fixedly connected to the swing rod 17. The support frame 19 is provided with a connecting groove 21 slidingly adapted to the connecting rod 20. Both the connecting rod 20 and the connecting groove 21 are arranged in an arc shape along the swing path of the swing rod 17.

[0053] The implementation principle of this embodiment is:

[0054] The servo motor 18 drives the rocker arm 17 to swing, thereby driving the rotating platform 2 and the drill rod 5 to swing. During the swinging process of the rocker arm 17, the swinging is more flexible and has a larger swinging range, and can be applied to more environments. Through the sliding adaptation of the connecting rod 20 and the connecting groove 21, the swinging range of the rocker arm 17 is limited, and the swinging of the rocker arm 17 is made more stable.

[0055] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
