All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 2 and fig. 3, the embodiment of the present invention provides a rotary drilling rig, which mainly includes a drill rod 1, a mast 2 (or referred to as a mast assembly), a machine body 8 and a walking chassis 10, wherein the drill rod 1 is a driving member for driving a drill bit to rotate and is disposed on the mast 2, the mast 2 is a member for supporting, carrying and connecting the drill rod 1, two connection portions of two ends of the drill rod 1 and two connection portions of the mast 2 are respectively close to a first end and a second end of the mast 2 (the first end and the second end are two ends of the whole mast 2), that is, a connection portion of one end of the drill rod 1 and the mast 2 is close to the first end of the mast 2, and a connection portion of the other end of the drill rod 1 and the mast 2 is close to the second end of the mast 2, and the mast 2 includes two portions, that is, a first mast 201 and a second mast 202, an end of the first mast 201 and an, the first mast 201 and the second mast 202 can be in straight line butt joint by relative rotation, and the height of the first end and the second end can be reduced to realize the reduction of the height of the drill rod 1, namely: when the rotary drilling rig needs to work, the first mast 201 and the second mast 202 are rotated forward relatively, so that the ends of the first mast 201 and the second mast 202 are butted to form a linear mast 2, the mast 2 in the state has the same shape as the mast in the prior art, and thus the drill rod 1 arranged on the mast 2 can work normally; when the rotary drilling rig needs to be transferred, the first mast 201 and the second mast 202 are rotated in opposite directions, so that the heights of the first end (the first end is the end of the first mast 201 far away from the second mast 202) and the second end (the second end is the end of the second mast 202 far away from the first mast 201) of the mast 2 are reduced, that is, the whole mast 2 is converted from a straight state to a bent state (i.e., the state is converted from the state shown in fig. 1 to the state shown in fig. 2), because the two ends of the drill rod 1 are connected with the parts close to the first end and the second end, the height of the drill rod 1 arranged on the mast 2 is reduced under the driving of the first end and the second end along with the reduction of the heights of the first end and the second end, that is, the middle of the whole mast 2 is bent to realize the downward movement of the two ends of the mast 2, and the downward movement of the whole drill rod 1 connected with the two ends is driven, and then make the height of whole rotary drilling rig reduce, so just so can make rotary drilling rig satisfy the transportation requirement of road.
The rotary drilling rig has the advantages that when the rotary drilling rig needs to be shifted, the transportation requirements of roads can be met only by bending the mast 2 and driving the drill rod 1 to move downwards, so that the drill rod 1 can be prevented from being disassembled, the drill rod 1 does not need to be disassembled, workload can be reduced, time is saved to improve shifting efficiency, the drill rod 1 is not disassembled, complete machine transportation of the rotary drilling rig can be achieved, the disassembled drill rod 1 does not need to be transported by other vehicles, the using quantity of transport vehicles can be reduced, and transportation cost can be remarkably reduced.
As shown in fig. 3, an end of the first mast 201 and an end of the second mast 202 are rotatably connected by a connection structure including: a first connecting member 3 connected to an end of the first mast 201, the first connecting member 3 being located at a bottom of the first mast 201; a second connecting member 4 connected to an end of the second mast 202, the second connecting member 4 also being located at a bottom of the second mast 202; a rotating shaft 5 rotatably connecting the first connecting member 3 and the second connecting member 4; a hydraulic cylinder 6 for applying force to the first mast 201 and the second mast 202, wherein the cylinder body of the hydraulic cylinder 6 is arranged on one of the first mast 201 and the second mast 202, and the extending end of the piston rod of the hydraulic cylinder 6 is connected with the other one of the first mast 201 and the second mast 202. The first connecting member 3, the second connecting member 4 and the rotating shaft 5 are structures capable of enabling the first mast 201 and the second mast 202 to rotate relatively, and are disposed at the bottom of the first mast 201 and the second mast 202, so as to enable the first end and the second end to move downwards when the first mast 201 and the second mast 202 rotate, that is, the first mast 201 and the second mast 202 can rotate relatively by moving the first end of the first mast 201 and the second end of the second mast 202 downwards. The connection structure further comprises a hydraulic cylinder 6, because the relative rotation of the first mast 201 and the second mast 202 needs to be driven, the hydraulic cylinder 6 is preferably arranged on the side walls of the first mast 201 and the second mast 202, since the cylinder body of the hydraulic cylinder 6 is rotatably arranged on one of the first mast 201 and the second mast 202, and the extending end of the piston rod of the hydraulic cylinder 6 is rotatably connected with the other (for example, the extending end of the piston rod is rotatably sleeved on the projection of the side wall of the projecting mast 2), when the piston rod extends out of the cylinder body, the hydraulic cylinder 6 can push one of the first mast 201 and the second mast 202 to rotate away from the other, so that the first mast 201 and the second mast 202 are converted from the straight butt joint state to the bending state, and when the piston rod retracts into the cylinder body, the hydraulic cylinder 6 can pull the first mast 201 and the second mast 202 to approach each other until the two butt joint, thereby, the first mast 201 and the second mast 202 are converted from a bending state to a straight butt state. In the embodiment, the reason why the hydraulic cylinder 6 is used to apply the acting force is that the hydraulic cylinder 6 has a small volume, can provide a large and stable acting force, and is also convenient to cooperate with a hydraulic pipeline, a hydraulic oil tank and the like on the rotary drilling rig, so that the hydraulic cylinder 6 is taken as a preferable driving component of the embodiment.
Further, the present embodiment further includes a locking mechanism for connecting the first mast 201 and the second mast 202 to keep the first mast 201 and the second mast 202 in a straight butt joint state. Since the state in which the first mast 201 and the second mast 202 are linearly butted is the working state of the mast 2, in this state, the mast 2 needs to be able to ensure the normal working of the drill rod 1, it is preferable to add a locking mechanism in order to more reliably ensure the maintenance of the linear state of the mast 2. The locking mechanism is used for locking the first mast 201 and the second mast 202 to prevent the first mast 201 and the second mast 202 from moving and/or rotating relatively, and on the basis, the locking mechanism can be structured in various ways, for example, the locking mechanism includes a locking plate, through holes are formed at two ends of the locking plate, screw rods protruding from the side walls are arranged on the side walls of the first mast 201 and the second mast 202, when the through holes at two ends of the locking plate are respectively penetrated by the screw rods on the first mast 201 and the screw rods on the second mast 202, the locking plate crosses the connecting part of the first mast 201 and the second mast 202, then nuts are screwed on the screw rods, locking of two ends of the locking plate is realized through screwing of the nuts and the screw rods, at the moment, the locking plate can realize locking of the first mast 201 and the second mast 202, so that the first mast 201 and the second mast 202 cannot move relatively, when the first mast 201 and the second mast 202 are required to be far away from each other, the locking plate can be detached; or, the side wall of the first mast 201 is provided with a rotatable annular buckle, the side wall of the second mast 202 is provided with a protruding fixture block, and when the first mast 201 is in butt joint with the second mast 202, the annular buckle can rotate to the position where the fixture block is located and be clamped with the fixture block, so that the first mast 201 and the second mast 202 can be locked.
In addition, since the first mast 201 and the second mast 202 are relatively rotated by the driving of the hydraulic cylinder 6, and the hydraulic cylinder 6 has a pressure maintaining function, the locking of the first mast 201 and the second mast 202 can also be realized by the tensile force applied to the first mast 201 and the second mast 202 by the hydraulic cylinder 6 on the premise that the hydraulic cylinder 6 has a sufficient rigidity and can apply a sufficient tensile force.
Specifically, as shown in fig. 2, a support rod 7 is arranged on a body 8 of the rotary drilling rig, the support rod 7 can support the first mast 201 with the reduced height, and the second mast 202 with the reduced height is supported by a luffing mechanism 9 of the rotary drilling rig. Since the mast 2 needs to be kept in a bent state when the rotary drilling rig is in a transition, the first mast 201 and the second mast 202 with reduced heights need to be supported to ensure the keeping of the bent state, on this basis, in this embodiment, the support rod 7 is additionally arranged on the machine body 8, the support rod 7 can be rotatably connected or detachably connected with the machine body 8, when the first mast 201 does not need to be supported, the support rod 7 can be rotated to a position that does not affect the normal operation of the rotary drilling rig, or the support rod 7 is detached from the machine body 8, and when the first mast 201 needs to be supported, one end of the support rod 7 is connected with the machine body 8, and the other end is connected with the first mast 201, as shown in fig. 2, so as to support the first mast 201. The second mast 202 is supported by the luffing mechanism 9 of the rotary drilling rig (the luffing mechanism 9 is an original structure of the rotary drilling rig).
In addition, similarly, under the premise that the hydraulic cylinder 6 has sufficient rigidity and can apply sufficient tension, the positioning after the first mast 201 and the second mast 202 are moved down can also be realized by applying tension to the first mast 201 and the second mast 202 by the hydraulic cylinder 6.
In the description, structures of all parts are described in a progressive mode, the structure of each part is mainly described to be different from that of the existing structure, and the whole structure and the partial structure of the rotary drilling rig can be obtained by combining the structures of the parts.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
