[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The output shaft of the gearbox of the present invention drives the input shaft of the steering gear to rotate through the universal joint coupling, and then the output shaft of the steering gear drives the transmission sleeve to rotate, the transmission sleeve drives the transmission shaft to rotate, the transmission shaft drives the sliding sleeve to rotate, the sliding sleeve drives the connecting sleeve to rotate through the transmission gear, the connecting sleeve rotates the drill rod, and thus through a series of transmissions, the gearbox drives the drill rod to rotate. At the same time, because the sliding sleeve is arranged on the transmission shaft, when the first lifting cylinder drives the rotator to lift, the rotator can drive the drill rod to rotate while descending, thereby realizing drilling construction. The steering gear has a simple structure, which can effectively reduce the transmission resistance and improve the working transmission efficiency. It is easy to implement and has low cost.

[0025] (2) The winch of the present invention is connected to the lifting device through a wire rope, which can meet the needs of drop hammer and impact drilling. In addition, the height of the overhead crane can be adjusted according to the construction needs, and then the height of the lifting device from the ground can be adjusted. When the height of the overhead crane needs to be adjusted, the third lifting cylinder generates a thrust on the upper mast. Under the action of this thrust, the upper mast rises upward along the guide tube, thereby raising the overhead crane. When the required height is raised, the positioning pin is inserted into the pin hole. With the help of the positioning pin and the pin hole, the position of the upper mast can be limited and fixed, and at the same time, the third lifting cylinder can be prevented from being damaged by continuous force. The operation is simple and reliable, which meets the actual construction needs.

[0026] (3) The present invention is provided with an angle adjustment member, which can drive the mast frame to rotate with the rotating support as the rotating axis, thereby making the drill rod present an inclined state, and then the gearbox drives the drill rod to rotate, and the first lifting cylinder drives the rotator to rise and fall to achieve inclined drilling. In addition, when drilling an inclined hole, the fourth lifting cylinder drives the top support inner frame to extend from the top support outer frame, and then the ejector plate is pressed against the ground, which can prevent the mast frame from swinging during the drilling operation, and can prevent the drilling hole from deviating, thereby improving the reliability of the device.

[0027] (4) The present invention adds an information collection and transmission system, which can monitor the equipment operation position quickly and accurately at any time, improve the operation management system, monitor and record the on-site exploration and drilling operation in real time, avoid fraud and exploration in restricted areas; improve the quality of exploration and drilling, realize dynamic supervision, and trace the quality and safety responsibility of the exploration site. The functionality and reliability of the device are improved.

[0028] (5) There are two types of adjustable anchor support frames of the present invention. When drilling an inclined hole, a long adjustable anchor support frame is used. The telescopic end of the fourth lifting cylinder is controlled to extend by operating a hydraulic control valve connected to the hydraulic oil pump. The fourth lifting cylinder drives the inner tube body of the top support inner frame to extend from the sleeve of the top support outer frame, thereby pressing the ejector plate against the ground. When a short adjustable anchor support frame is used, the adjusting screw is rotated, the bottom end of the adjusting screw moves downward, the channel steel plate moves downward, and then the limit rod is driven to move downward from the bottom of the limit tube, so that the ejector plate is pressed against the ground. This can prevent the mast frame from swinging during the inclined hole operation and the drilling hole position from deviating, thereby improving the reliability of the device. The device can be selected according to actual working conditions, thereby improving the practicality of the device.

[0029] (6) The present invention is provided with a rope retractor, which can select the direction of rope retraction according to the actual force direction and prevent the winch wire rope from being dislocated due to force.

[0030] (7) The present invention is based on solving the problems existing in existing drilling rigs. It designs multiple components such as a steering gear, a mast frame, a lifting drive, a rotator and an angle adjustment component, and designs the specific structure of the components to meet the requirements of 0-90° angle drilling. During the drilling process, the transmission process is stable and reliable, which can effectively reduce the transmission resistance and improve the work transmission efficiency. In addition, the entire device is stable and reliable, easy to implement and low in cost, which meets the actual construction needs. And by improving the location of the component settings, it is convenient for the operator to understand the drilling work status more intuitively. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] The lifting drive member 4 is arranged at the front side of the mast frame 3, and the lifting drive member 4 includes a first lifting cylinder 41 symmetrically arranged at the front side of the mast frame 3, a vertical guide rail 42 fixed on the mast frame 3 and located at the rear side of the first lifting cylinder 41, and a slide seat 43 arranged on the guide rail 42 and slidingly guided with the guide rail 42; wherein the top of the cylinder body of the first lifting cylinder 41 is sleeved in the guide sleeve 40 fixed on the top of the mast frame 3, and the bottom telescopic end of the first lifting cylinder 41 is vertically hinged downward to the mast frame 3;

[0064] A rotator 5 is connected to the lifting drive member 4 and driven by the lifting drive member 4 to be lifted and lowered along the mast frame 3 and is connected to the transmission shaft 31 in transmission connection; in the present embodiment, the rotator 5 and the slide seat 43 are fixedly connected to the cylinder body of the first lifting cylinder 41; more specifically, a sliding sleeve 51 is provided in the housing of the rotator 5, which is sleeved on the transmission shaft 31 and can slide up and down along the transmission shaft 31; a connecting sleeve 52 for connecting a drill pipe is also provided in the housing of the rotator 5; the sliding sleeve 51 and the connecting sleeve 52 are both rotatably connected to the housing of the rotator 5, and are transmitted through gear meshing.

In this way, when the transmission shaft 31 drives the sliding sleeve 51 to rotate, the sliding sleeve 51 drives the transmission gear 53 to rotate through the teeth on its outer wall, and the transmission gear 53 drives the connecting sleeve 52 to rotate through the teeth on the outer wall of the connecting sleeve 52. Through this series of transmission, the transmission shaft 31 drives the connecting sleeve 52 of the gyrator 5 to rotate, and then drives the drill rod to rotate, thereby achieving a drilling effect;

[0065] An angle adjustment member 6 is arranged at the rear side of the mast frame 3 and adjusts the tilt angle of the mast frame 3. In this embodiment, the angle adjustment member 6 is a second lifting cylinder. The bottom of the second lifting cylinder is hinged on the machine base 1 that can slide forward and backward and is located at the rear side of the mast frame 3. The top of the second lifting cylinder is hinged at the middle of the mast frame 3.

[0066] In order to improve the stability of the mast frame 3 after it is tilted, an auxiliary diagonal brace 7 is provided at the position of the forward and backward sliding machine base 1 located on the rear side of the mast frame 3. The auxiliary diagonal brace 7 includes an outer diagonal brace tube 71 hinged at the bottom to the forward and backward sliding machine base 1, an inner diagonal brace tube 72 hinged at the top to the mast frame 3 and extending into the outer diagonal brace tube 71 at the bottom, and a locking clamp 73 for fixing the relative positions of the outer diagonal brace tube 71 and the inner diagonal brace tube 72. It should be additionally explained here that the locking clamp 73 can be the following structure: the locking clamp 73 has two opposing semicircular clamps, and the two semicircular clamps are locked by bolts to clamp the connection between the outer diagonal brace tube 71 and the inner diagonal brace tube 72, thereby fixing the relative positions of the outer diagonal brace tube 71 and the inner diagonal brace tube 72.

[0067] In this embodiment, a crane 8 is provided at the top of the mast frame 3, and an upper mast 81 is symmetrically fixed on the top of the crane 8. The bottom of the upper mast 81 passes through the guide tube 32 fixed at the top of the front side of the mast frame 3 and is connected to the telescopic end of the third lifting cylinder 33; wherein, the bottom of the third lifting cylinder 33 is vertically connected to the mast frame 3 downward; pin holes 811 are evenly spaced at a position of the upper mast 81 near the bottom of the third lifting cylinder 33.

[0068] A multi-speed gearbox and a winch 14 are fixed on the machine base 1 that can slide forward and backward. The wire rope 15 on the winch 14 passes through a rope collector 10 fixed on the winch 14, the bottom of the rear side of the mast frame 3, and the guide pulleys 82 at the rear and front ends of the crane 8, and is connected to a hoist 83. The hoist 83 is suspended on the front side of the crane 8. The rope collector 10 includes an oblique support frame 101 fixed on the machine base 1 that can slide forward and backward, a fixed sleeve 102 fixed on the top of the oblique support frame 101, and a fixed sleeve 102 sleeved in the fixed sleeve 102 and connected to the fixed sleeve 102. The fixed sleeve 102 is rotatably matched with the column 103, the fixed sleeve 104 is rotatably connected to the bottom of the column 103 and fixedly connected to the machine base 1 that can slide forward and backward (the fixed sleeve 104 has a bearing inside, and the column 103 is fixedly connected to the inner ring of the bearing in an interference fit manner), the mounting plate 105 fixed to the top of the column 103, and two pulley blocks 106 installed on the mounting plate 105 at intervals, and the auxiliary sleeve 107 is sleeved in the middle of the column 103 and rotatably connected to the column 103 and fixed to the machine base 1 that can slide forward and backward. In addition, the structural diagram of the guide pulley 82 at the position of the rotating support 11 can be seen in Fig.12 A pulley is installed on the top of each of the two metal plates that are spaced apart. Another metal plate is vertically fixed on one side of the two metal plates that are close to each other. Two pulleys are installed between the two metal plates at intervals.

[0069] In addition, in the present embodiment, an adjustable anchor support frame 9 is fixed to the bottom of the rear side of the mast frame 3, and the adjustable anchor support frame 9 includes an outer support frame 91 fixed to the bottom of the mast frame 3, an inner support frame 92 slidingly guided with the outer support frame 91, a pin plate 93 hinged to the bottom of the inner support frame 92, and a fourth lifting cylinder 94 whose upper end is hinged to the top of the outer support frame 91 by a fixing pin and whose lower end is hinged to the bottom of the inner support frame 92 by a fixing pin; wherein, two rectangular sleeves 911 are symmetrically arranged on the outer support frame 91, and inner tube bodies 921 inserted into the sleeves 911 are symmetrically arranged on the inner support frame 92; the adjustable anchor support frame of this arrangement is long.

[0070] Alternatively, the adjustable anchor support frame 9 includes two stopper tubes 95 fixed at intervals at the bottom of the mast frame 3, a stiffening plate 96 fixedly connected between the two stopper tubes 95, an adjusting screw 97 threadedly connected to the stiffening plate 96; the bottom of the adjusting screw rod 97 passes through the stiffening plate 96 and is rotatably connected to a slotted steel plate 98, two stopper rods 99 inserted into the stopper tubes 95 are fixed at intervals at the top of the slotted steel plate 98, and a pin plate 93 is hinged at the bottom of the two stopper rods 99. The adjustable anchor support frame of this arrangement is short.

[0071] Finally, in this embodiment, a hole centralizer 39 is fixed to the front side of the mast frame 3 below the rotator 5; the hole centralizer 39 includes a fixing plate 391 fixedly connected to the mast frame 3 and a hole plate 392 fixedly connected to the fixing plate 391 and perpendicular to the mast frame 3, and a limit sleeve 393 with an adjustable center bearing is installed in the middle of the hole plate 392. When in use, the top of the drill pipe is connected to the connecting sleeve 52 on the rotator 5, and the bottom passes through the limit sleeve 393, so that the drill pipe can be offset when drilling.

[0072] It should be noted that the forward and backward sliding machine base 1 is also provided with a hydraulic oil pump 16 connected to the first lifting cylinder 41, the second lifting cylinder, the third lifting cylinder 33 and the fourth lifting cylinder 38; when the power assembly 12 (diesel engine) is working, the gearbox 13 and the hydraulic oil pump 16 are driven by the provided pulleys and belts to provide power.

[0073] When the diesel engine of the power assembly 12 is working, the gearbox 13 is driven to work through the pulley and the belt. The output shaft of the gearbox 13 drives the input shaft of the steering gear 2 to rotate through the universal joint coupling 21, and then the output shaft of the steering gear 2 drives the transmission sleeve 22 to rotate. When the transmission sleeve 22 rotates, it drives the transmission shaft 31 to rotate, the transmission shaft 31 drives the sliding sleeve 51 to rotate, the sliding sleeve 51 drives the transmission gear 53 to rotate, the transmission gear 53 drives the connecting sleeve 52 to rotate, the connecting sleeve 52 rotates, and the drill rod rotates (the drill rod is fixedly connected to the connecting sleeve 52). In this way, through a series of transmissions, the gearbox 13 drives the drill rod to rotate.

[0074] When drilling a straight hole, the rotator 5 is raised to the top of the mast frame 3, specifically: the first lifting cylinder 41 is controlled to extend by operating the hydraulic control valve connected to the hydraulic oil pump 16. When the telescopic end of the first lifting cylinder 41 is extended, the cylinder body of the first lifting cylinder 41 rises along the guide sleeve 40, and the cylinder body of the first lifting cylinder 41 drives the rotator 5 to rise. When drilling, the telescopic end of the first lifting cylinder 41 is controlled to retract, the cylinder body of the first lifting cylinder 41 drives the rotator 5 to descend, and the sliding sleeve 51 slides downward along the transmission shaft 31. It should be supplemented here that when the transmission shaft 31 rotates, the sliding sleeve 51 slides down and rotates along the transmission shaft 31, so that the rotator 5 drives the drill rod to rotate while descending, and the drilling construction is realized. In addition, during the lifting and lowering process of the cylinder body of the first lifting cylinder 41, the sliding guide cooperation of the slide seat 43 and the guide rail 42 can limit the lifting and lowering of the first lifting cylinder 41 to avoid the deviation of the drill rod hole position and improve the stability of the device.

[0075] When drilling an inclined hole, the telescopic end of the second lifting cylinder is controlled to retract by operating the hydraulic control valve connected to the hydraulic oil pump 16. The second lifting cylinder generates a pulling force on the mast frame 3, and the mast frame 3 rotates around the rotating support 11. When it rotates to a suitable inclination angle, the retraction of the telescopic end of the second lifting cylinder is stopped, so that the drill rod is in an inclined state. Subsequently, the drill rod is driven to rotate through the gearbox 13, and the first lifting cylinder 41 drives the rotator 5 to rise and fall to achieve inclined drilling. In addition, when drilling an inclined hole, when using a long adjustable anchor support frame 9, the telescopic end of the fourth lifting cylinder 94 is controlled to extend by operating the hydraulic control valve connected to the hydraulic oil pump 16, and the fourth lifting cylinder 94 drives the inner tube body 921 of the top support inner frame 92 to extend from the sleeve 911 of the top support outer frame 91, thereby pressing the ejector plate 93 against the ground; when using a short adjustable anchor support frame 9, the adjusting screw 97 is rotated, the bottom end of the adjusting screw 97 moves downward, the channel steel plate 98 moves downward, and then drives the limit rod 99 to move downward from the bottom of the limit tube 95, so that the ejector plate 93 is pressed against the ground, which can prevent the mast frame 3 from swinging during the inclined hole operation, and prevent the drilling hole from deviating, thereby improving the reliability of the device.

[0076] In this embodiment, the winch 14 is connected to the lifter 83 through the wire rope 15, which can meet the needs of drop hammer and impact drilling. When it is necessary to adjust the height of the overhead crane 8, the telescopic end of the third lifting cylinder 33 is controlled to extend by operating the hydraulic control valve connected to the hydraulic oil pump 16, and the third lifting cylinder 33 generates a thrust on the upper mast 81. Under the action of this thrust, the upper mast 81 rises upward along the guide tube 32, thereby raising the overhead crane 8. When the required height is raised, the positioning pin is inserted into the pin hole 811. It should be noted here that at this time, multiple pin holes 811 will be exposed from the top of the guide tube 32. With the help of the positioning pin and the pin hole 811, the position of the upper mast 81 can be limited and fixed, and at the same time, the third lifting cylinder 33 can be prevented from being damaged by continuous force.
