The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.

As shown in fig. 1-6, the present embodiment provides an anchoring drill that includes a main mast 10, an elongated mast 20, and an anchoring mechanism 30. Wherein the elongate mast 20 is selectively connectable with the main mast 10 to form an elongate mast mechanism. The anchor mechanism 30 may be selectively coupled to the main mast 10 or alternatively coupled to an elongated mast mechanism.

According to the arrangement, referring to fig. 1, the anchoring mechanism 30 is directly connected with the main mast 10, so that the anchoring drilling machine can enter a standard anchoring mode, namely, the anchoring drilling machine is formed, referring to fig. 2 or 4, the anchoring mechanism 30 is connected with the lengthening mast mechanism, so that the anchoring drilling machine can enter a lengthening anchoring mode, the drilling depth is increased, the drilling requirements of more depths are met, the equipment utilization rate is improved, and the cost is reduced.

In terms of specific parameters, the anchoring drilling machine provided by the embodiment has the drilling depth of 0-12m in a standard anchoring mode, the maximum drilling diameter can reach 120-150 mm when the inclination angle of the main mast 10 relative to the ground is 15-45 degrees, and the maximum drilling diameter can reach 200mm when the main mast 10 is vertical to the ground. The length of the extension mast 20 is preferably 3m, and by connecting the main mast 10 to the extension mast 20, the maximum drilling depth of the anchor drilling machine in the extension anchor mode can be 15m.

In this embodiment, as shown in fig. 2, a first connection structure 11 is provided at the upper end of the main mast 10, and the extension mast 20 can be connected to the main mast 10 through the first connection structure 11 to form an extension mast mechanism, thereby realizing top extension. As shown in fig. 4, a second connecting structure 12 is arranged at the lower end of the main mast 10, and the extension mast 20 can also be connected with the main mast 10 through the second connecting structure 12 to form an extension mast mechanism, so that the bottom extension is realized, and the overall extension mode is flexible.

Preferably, the long mast 20 is optionally connected to the main mast 10 by a first connection 11 to achieve top lengthening, when the angle between the main mast 10 and the ground is greater than 45 ° and not greater than 90 °.

Referring to fig. 2, when the angle between the main mast and the ground is greater than 45 ° and not greater than 90 °, since the distance between the main mast 10 and the ground is small, if the extension mast 20 is added to the lower portion of the main mast 10, the bottom of the extension mast 20 touches the ground, and the extension mast mechanism cannot be erected as a whole, it is preferable to select to mount the extension mast 20 to the top of the main mast 10, i.e., to perform top extension.

Preferably, the elongated mast 20 is selectively connected to the main mast 10 by the second connection structure 12 to achieve bottom elongation when the angle between the main mast 10 and the ground is not greater than 45 ° and not less than 0 °.

Referring to fig. 4, when the angle between the main mast 10 and the horizontal direction is not more than 45 ° and not less than 0 °, it is appropriate to choose to mount the extension mast 20 to the bottom of the main mast 10, i.e., to perform bottom extension, because the distance between the main mast 10 and the ground is large. Meanwhile, in the case, the center of gravity of the whole anchoring drilling machine can be moved forward by lengthening the bottom, so that the anchoring drilling machine is prevented from turning backwards.

Of course, in other embodiments, top lengthening or bottom lengthening may be selected as the case may be. For example, when the angle between the main mast 10 and the horizontal direction is not more than 45 ° and not less than 0 °, if the overall weight of the anchoring drill can be kept balanced after the top extension, the top extension may be selected.

In this embodiment, the first connection structure 11 includes a first butt flange, and a first connection hole is provided on the first butt flange, so as to realize flange connection at the top of the main mast 10, and ensure convenience and stability of mast connection. The second connection structure 12 comprises a second docking flange provided with second connection holes for flange connection at the bottom of the main mast 10.

As shown in fig. 7, a first mating flange 21 is formed at the upper end of the elongated mast 20, and a second mating flange 22 is formed at the lower end of the elongated mast 20. The first mating flange 21 can be mated with a first mating flange to mount the elongated mast 20 directly to the top of the main mast 10, and the second mating flange 22 can be mated with a second mating flange to mount the elongated mast 20 directly to the bottom of the main mast 10.

In the actual connection of the extension mast 20, the extension mast 20 is flexibly positioned, and may be directly connected to the main mast 10 or indirectly connected to the main mast 10.

In one aspect, referring to fig. 2 and 3, an anchor mast 34 is provided in the anchor mechanism 30, and the elongate mast 20 is connected to the top of the main mast 10 by the anchor mast 34. More specifically, as shown in fig. 8, a third mating flange 341 is formed at the lower end of the anchor mast 34, a fourth mating flange 342 is formed at the upper end of the anchor mast 34, the first mating flange is mated with the third mating flange 341, and the fourth mating flange 342 is mated with the first mating flange 21 to achieve top lengthening. On the other hand, referring to fig. 4 and 5, the extension mast 20 is directly connected to the bottom of the main mast 10 to achieve bottom extension.

In this embodiment, the masts such as the main mast 10, the lengthened mast 20, and the anchor mast 34 are all rectangular box-type structures, which have small volume, high strength and light weight, and can ensure the stability of the whole machine. Preferably, the mast side length is 350mm-400mm.

In another embodiment, the masts are connected in a folding manner in addition to being fixed by a flange structure, for example, the first connecting structure 11 can be connected with the extension mast 20 in a folding manner, and the second connecting structure 12 can be connected with the extension mast 20 in a folding manner. Specifically, referring to fig. 9, a pin 13 may be provided at the end of the main mast 10. When the main mast 10 and the lengthened mast 20 are in butt joint, three sides of each of the two masts are fixedly connected through a flange structure, the installation is firm, the two masts are not easy to shake, and one side of each of the two masts is hinged through a pin shaft 13. After the flange bolts are disassembled, folding between the two masts can be achieved through the rotating pin shafts 13, storage is carried out, and rapid installation can be achieved when the next working is convenient. The structure is mainly suitable for the condition that the whole transportation length of the anchoring drilling machine is limited, and under the condition, the mast with the shorter top or bottom is not required to be detached.

Next, the anchoring mechanism 30 will be further described.

As for the anchoring mechanism 30, as shown in fig. 1, it includes an anchor drill 31 and an anchor pulley frame 32, and the anchor pulley frame 32 is detachably connected with the upper end of the main mast 10 or the upper end of the elongated mast mechanism to be mounted to the anchor drill. Referring to fig. 1 and 8, a first pulley 321 is provided on the anchor pulley frame 32, and the first pulley 321 is located on the extension line of the main mast 10. In this embodiment, the anchor pulley frame 32 has an overall length of about 2m.

Preferably, the weight of the anchor pulley frame 32, the elongated mast 20, the anchor mast 34, and the main mast 10 are sequentially increased to move the center of gravity downward as much as possible when the top of the anchor drilling machine is elongated, which is advantageous for maintaining the balance of the anchor drilling machine.

For the anchoring drilling tool 31, reference is made to fig. 1, which includes an anchoring power head 311, a auger stem 312, and a guide casing 313. The anchoring power head 311 is connected to the top of the auger stem 312 through a flange plate to drive the auger stem 312 to move, and the guiding casing 313 is sleeved on the bottom of the auger stem 312 to guide the auger stem 312. The first connection string 50 is connected to an upper portion of the anchoring power head 311 around the first pulley 321 to lift the anchoring drilling tool 31.

At this time, since the first connecting rope 50 can be connected to the side of the anchoring power head 311 close to the main mast 10, the first connecting rope 50 can be normally wound without reserving excessive winding space for the first connecting rope 50, and the first pulley 321 is provided to ensure the normal winding installation of the first connecting rope 50, so that the structure is compact.

Referring to fig. 1, the anchoring drilling machine further includes a secondary winch 60 and a second connection string 70, the secondary winch 60 being connected to the anchoring drilling tool 31 through the second connection string 70 to provide pressurizing force. In this embodiment, referring to fig. 9, a second pulley 343 is provided on the anchor mast 34, and a second connection rope 70 is connected to the lower portion of the anchor power head 311 around the second pulley 343 to provide pressurizing force.

In this embodiment, when the top of the anchoring drill is lengthened, the anchoring power head 311 is installed from the bottom, that is, the stopper at the lower part of the main mast 10 is removed when the main mast 10 is in the standing state, the anchoring power head 311 is threaded through the slide rail from the lower part of the main mast 10, and the crane lifts the anchoring power head 311, so that the anchoring power head 311 is connected with the first connection rope 50 and the second connection rope 70. When the bottom of the anchoring drilling machine is lengthened, the anchoring power head 311 is firstly installed in a mast standing state, then the first connecting rope 50 is connected with a lifting point at the top of the anchoring power head 311, and after the main mast 10 is inverted, the lengthened mast 20 is installed.

Illustratively, the torque of the anchor power head 311 is 100 kN.m-180 kN.m, the lifting force of the main winch 40 is 120kN-180kN, and the pressurizing force provided by the auxiliary winch is 10kN-50kN. In terms of material, the first connecting cord 50 and the second connecting cord 70 are both steel cords.

Optionally, the anchoring mechanism 30 further comprises a grouting assembly 33, and the grouting assembly 33 is detachably connected with the anchoring drill 31 for grouting.

The screw rod 312 has a hollow structure, one end of the grouting hose 331 is connected with a vehicle pump or a drag pump on the ground, and the other end is connected with the hollow part of the screw rod 312 through a grouting elbow 332 to perform grouting operation.

Further, a return bend is provided at the junction of the slip bend 332 and the auger stem 312 to prevent the slip bend 332 from rotating as the auger stem 312 rotates. The grouting elbow 332 is also connected with the anchoring power head 311 through a limiting rod, so as to prevent the grouting elbow 332 from swinging freely. In this embodiment, the grouting hose 331, grouting elbow 332 and auger stem 312 have a grouting diameter of 60mm-80mm.

It will be appreciated that when the main mast 10 is connected to the elongate mast 20, both the auger stem 312 and the grouting hose 331 are required to be elongate.

When the construction is not needed, taking the case that the anchoring drilling machine is in the standard anchoring mode as shown in fig. 1 and 10, the anchoring drilling machine can be put into a transportation state by lowering the main mast 10 to be substantially parallel to the ground, removing the grouting hose 331, and then disconnecting the fixation between the grouting elbow 332 and the limit rod, so that the grouting elbow 332 sags and is fixed to the side surface of the main mast 10.

Finally, the other main structure of the anchoring drilling machine will be described.
