Description
Technical Field
The invention relates to the technical field of soil and rock drilling equipment, in particular to a top hammer type pipe following drilling propeller and drilling equipment.
Background
In the field of construction, the setting of the drilling depth is often a relatively strict requirement. When the drilling depth is deeper, the traditional reinforcing mode of drilling is that an open-air drilling machine is used for drilling downwards on the construction ground, then grouting is performed in the drilling hole, and the slurry is solidified to form a reinforcing structure. However, in the case of complex strata such as fractured zones and fractured zones, after the drill bit withdraws from the drilled hole, the hole wall of the drilled hole loses support, and the hole collapse phenomenon is easy to occur. In order to avoid the occurrence of hole collapse, the current commonly used hole protection mode is that after a drill rod exits from a drill hole, a steel casing is inserted into the drill hole, and then grouting is performed into the casing so as to stabilize the stratum.
However, due to the limitation of the length of the steel casing, the above hole protecting mode can only achieve the function of stabilizing the stratum at the part of the drill hole close to the top end, and the part of the drill hole where the steel casing cannot reach still has the risk of hole collapse, so that a great potential safety hazard exists.
In order to solve the problems, the pipe following drilling in the prior art is a feasible construction mode. Generally, the drilling tools for drilling along with the pipe include a concentric drilling tool and an eccentric drilling tool, such as the concentric drilling tool disclosed in chinese patent No. 2012102948866 and the eccentric drilling tool disclosed in the down-the-hole hammer disclosed in chinese patent No. 2003201152028. Meanwhile, in the pipe-following drilling in the prior art, the pipe-following drilling is usually realized by using a down-the-hole hammer drilling tool or a drill bit, such as a down-the-hole hammer pipe-following drill bit disclosed in chinese patent application No. 2014108498585, a down-the-hole concentric pipe-following reaming drilling tool disclosed in chinese patent application No. 2008200543648, and a down-the-hole hammer reverse circulation concentric pipe-following drilling tool disclosed in chinese patent application No. 2010102750305.
In general, in the field of construction, down-the-hole hammer drills are suitable for drilling of vertical piles or drilled holes requiring high performance, such as large-diameter and deep holes, and are often used for drilling of pre-buried holes/drilled holes perpendicular to the ground. However, in other fields, the down-the-hole hammer drill occupies a large space, has a heavy front part, has low drilling efficiency, and is not suitable for drilling construction of short holes, straight holes and inclined holes in complex geological environments.

For a further understanding of the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings and examples.
The structure, proportion, size and the like shown in the drawings are only used for matching with the content disclosed in the specification, so that the person skilled in the art can understand and read the description, and the description is not used for limiting the limit condition of the implementation of the invention, so the method has no technical essence, and any structural modification, proportion relation change or size adjustment still falls within the scope of the technical content disclosed by the invention without affecting the effect and the achievable purpose of the invention. In addition, the terms "upper", "lower", "left", "right" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the relative positions may be changed or adjusted without substantial technical changes.
In the field of building, down-the-hole hammer type pipe-following drilling equipment is common vertical drilling construction equipment, namely common construction equipment for drilling holes perpendicular to the ground. However, due to the structural limitation of the down-the-hole hammer type drill rod, the down-the-hole hammer type pipe following drilling equipment has high requirement on the height of the field space, and the drill bit part of the down-the-hole hammer type drill rod has heavy weight and large size, so that the drilling of the thin and short drill holes is difficult to realize, and therefore, the down-the-hole hammer type pipe following drilling equipment is particularly not suitable for drilling construction with complex geological environment and complex field environment.
For example, in the process of collapse prevention treatment in the subway construction process or in the process of treatment after the subway collapse is generated, excavation construction needs to be carried out after reinforcement is carried out on a crack zone, a broken zone and a collapse section of a foundation, but due to the influence of the structure of the underground hammer type pipe-following drilling equipment, the underground hammer type pipe-following drilling equipment cannot enter a construction site, and therefore the underground collapse prevention and treatment method is not suitable for the underground collapse prevention and treatment.
In the prior art, top hammer rock drills are the drilling drive of rock drilling equipment. When the top hammer type rock drill drives the drill rod to drill, the driving force of the top hammer type rock drill acts on the top end of the drill rod, namely, acts on one end of the drill rod connected with the moving end of the top hammer type rock drill, and the drilling mode is called top hammer type drilling in the embodiment mode.
The thruster provided by the embodiment adopts a top hammer type drilling mode, so that the overall size of the thruster is smaller, and the size of the drilling equipment provided with the embodiment can adapt to a complex field environment; simultaneously, this embodiment top hammer formula is followed pipe and is bored the propeller and can be when boring to the interior configuration sleeve pipe of drilling to prevent the hole phenomenon of collapsing of drilling, and then improve the stability of drilling structure.
Specifically, referring to fig. 1, the top-hammer type pipe-following drilling thruster of the present embodiment includes a top-hammer type rock drill 300, a main pipe-following assembly 600, a drill clamp 500, and a thrust beam 700. Wherein the top hammer rock drill 300 is slidably arranged on the feed beam 700 and is movable in a first direction, and the drill clamp 500 is arranged on the feed beam 700 near the front end. It should be noted that, in the present embodiment, the first direction refers to a length direction of the feed beam 700, for example, an x direction indicated in fig. 1, the second direction refers to a height direction of the feed beam 700, for example, a y direction indicated in fig. 1, and the third direction refers to a width direction of the feed beam 700, for example, a z direction indicated in fig. 1; the top hammer rock drill 300 described in the present embodiment moving in the first direction means that the top hammer rock drill 300 can advance and retreat in the first direction.
The main heel tube assembly 600 comprises a main drill rod and a main sleeve, wherein the main sleeve is sleeved on the main drill rod; the length of the main casing is less than the length of the main drill rod, so that the end of the main drill rod close to the top hammer rock drill 300 can be exposed out of the main casing, thereby facilitating the installation/extension of the main drill rod.
The first connecting end of the main drill rod is connected with the head of the main sleeve in a matching mode, namely, a drill bit is arranged on the first connecting end of the main drill rod, and when the main drill rod rotates, the drill bit is in transmission connection with the head of the main sleeve, so that the head of the main sleeve can be driven to rotate relative to the pipe body of the main sleeve, and meanwhile, the pipe body of the sleeve is arranged in a drilled hole under the traction of the head of the pipe body, and the pipe following drilling is achieved. The first connection end of the main drill rod and the matching connection structure of the head of the main casing can refer to the connection structure of the drill rod and the casing in the down-the-hole hammer type casing drilling equipment, such as, but not limited to, chinese patent document No. 2012102948866 and chinese patent document No. 2003201152028.
The second link of kelly is connected with top hammer rock drill 300 drivably, namely, the power of the motion end of top hammer rock drill 300 can be transmitted to the second link of kelly, and this power both includes the rotatory rotational drive power of drive kelly, has also included the impact force that drives the kelly and gos forward to realize top hammer rock drill 300 to the drive of creeping into of kelly. The second connecting end of the main drill rod is in transmission connection with the top hammer type rock drill 300, namely, the second connecting end can be directly connected with the moving end of the top hammer type rock drill 300 and can also be connected through a transmission piece; in some scenarios, the transmission may be an additional drill rod 110, thereby increasing the drilling depth of the drill of the present embodiment.
For example, in drilling construction, if the design depth of the drill hole is high and the length of the main drill pipe and/or the main casing is less than the design depth of the drill hole, extension rods and/or adapter pipes are generally required to achieve an extension of the drilling depth. Meanwhile, in the embodiment, because the length of the main casing is smaller than that of the main drill rod, the drilling depth is usually extended only in two ways, namely, only connecting pipes are used for connecting the main casing and the main drill rod, namely, the length of the casing is extended; the other is to perform extension rods and joints, i.e. to extend the length of the drill pipe and casing.
In the first mode, the top hammer type rock drill 300 drives the main heel tube assembly 600 to drill from the rear end of the push beam, after the tail end of the main casing passes through the drill clamp 500, the drill clamp 500 clamps the main drill rod, the main drill rod and the top hammer type rock drill 300 complete rod disassembly, the top hammer type rock drill 300 returns to the rear end of the push beam, then the additional casing is sleeved on the main drill rod, the tail of the main casing is connected with the head of the additional casing, and then the top hammer type rock drill 300 moves to the second connecting end of the main drill rod to be connected with the main drill rod connecting rod, and the main heel tube assembly 600 is continuously driven to drill.
As for the second mode, after the tail end of the main casing passes through the drill clamp 500, the drill clamp 500 clamps the main drill rod, the main drill rod and the top hammer type rock drill 300 complete rod disassembly, the top hammer type rock drill 300 retracts to the rear end of the push beam, then the additional drill rod 110 is conveyed to the pipe connecting position, the first connecting end 111 of the additional drill rod 110 is connected with the second connecting end of the main drill rod, then the sheathing of the additional casing is completed, the connection between the additional casing and the main casing is completed, and the top hammer type rock drill 300 is moved to the second connecting end 112 of the additional drill rod 110 to be connected with the additional drill rod 110. The extension rod position of the additional drill rod 110 means that the additional drill rod 110 is placed on the feed beam 700 with the first connector 111 capable of driving connection with the main drill rod and the second connector 112 capable of being connected with the top hammer rock drill 300.
Of course, in some situations, when the pipe connecting/pipe connecting operation is required to be performed several times according to the designed depth of the borehole, the specific operation process may refer to the two manners described above, that is, after the main casing/additional casing at the end in the first direction passes through the drill clamp 500, the main drill pipe/additional drill pipe is clamped by the drill clamp 500, and then the pipe connecting/pipe connecting operation is performed.
In the following, the following description is given,

The storage state refers to a state in which the additional drill rod 110 is accommodated in the magazine 200 when the extension rod is not needed. In addition, the stopping portion 230 is further provided with a notch 231 for allowing the additional drill rod 110 to be removed from the storage magazine 200, and when the rotating shaft 212 rotates relative to the push beam 700, the rotating shaft also rotates relative to the stopping portion 230; when the rotating shaft 212 is rotated to a specific position, one of the additional drill rods 110 clamped on the chuck 220 is located at a position corresponding to the notch 231, i.e., in a standby state, and the robot 240 can take out the additional drill rod 110 from the magazine 200 and transport it to the extension rod position. The standby state means a state in which the additional drill rod 110 can be transported to the position of the extension rod to extend the extension rod.
