In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

Example:

As shown in Figures 1, 2 and 3, the anchor pipe device provided in this embodiment includes an anchor pipe 1 and a driving assembly 2; the pipe body of the anchor pipe 1 is provided with a slit 3, one end and the other end of the slit 3 are arranged at intervals, and a bending part is provided between the two ends of the slit 3, and the bending part is used to make the slit 3 form a semi-closed ring structure; the pipe body of the anchor pipe 1 located in the inner ring space of the slit 3 is an external insertion part 10, and the output end of the driving assembly 2 is arranged in the anchor pipe 1 and on one side of the external insertion part 10, and the driving assembly 2 is used to drive the external insertion part 10 to tilt in a direction away from the inside of the anchor pipe 1 and insert into the soil around the anchor pipe 1.

When using the anchor pipe device, the anchor pipe 1 can be driven into the soil first. At this time, the external insertion part 10 at the cut slit 3 of the anchor pipe 1 is not raised, so the anchor pipe 1 is smooth, and the external insertion part 10 will not hinder the process of the anchor pipe 1 drilling into the soil, so the construction efficiency of the anchor pipe 1 can be improved.

After the anchor pipe 1 is drilled into the soil, the output end of the driving component 2 can be extended into the anchor pipe 1, and the output end of the driving component 2 can be located on one side of the external plug-in portion 10. Then the driving component 2 can be started, and the power output from the output end of the driving component 2 can be used to drive the external plug-in portion 10 to tilt in a direction away from the inside of the anchor pipe 1. After the external plug-in portion 10 is tilted, it can be inserted into the soil around the anchor pipe 1, thereby improving the anchoring strength between the anchor pipe 1 and the soil, and effectively ensuring the stability of the anchor pipe 1 in the soil.

Compared with the prior art, the anchor pipe device provided in this embodiment can improve the anchoring strength between the anchor pipe 1 and the soil without hindering the anchor pipe 1 from drilling into the soil and improving the construction efficiency by preventing the external insertion part 10 at the cut 3 from curling up during the process of the anchor pipe 1 drilling into the soil, and using the driving component 2 to make the external insertion part 10 curl up and insert into the soil around the anchor pipe 1 after the anchor pipe 1 drills into the soil.

As shown in Figures 1 and 2, the external insertion part 10 includes a connecting end 100 and a tilted end 101, the connecting end 100 is located between the two ends of the slit 3, and the tilted end 101 can move away from the inner direction of the anchor pipe 1; the anchor pipe 1 includes a head end 11 and a tail end 12 drilled into the soil after the head end 11, and in the projections of the head end 11, the tail end 12, the connecting end 100 and the tilted end 101 of the anchor pipe 1 on the central axis of the anchor pipe 1, the projection of the tilted end 101 is located between the projection of the connecting end 100 and the projection of the head end 11 of the anchor pipe 1.

In actual application, after the external plug-in part 10 is driven by the driving assembly 2 to tilt up, the external plug-in part 10 is more likely to be set at an acute angle with the pipe body of the anchor pipe 1. Therefore, when the projection of the tilted end 101 is located between the projection of the connection end 100 and the projection of the head end 11 of the anchor pipe 1, the acute angle formed between the external plug-in part 10 and the anchor pipe 1 after tilting up will be toward the head end 11 of the anchor pipe 1. At this time, the external plug-in part 10 can not only improve the anchoring strength between the anchor pipe 1 and the soil, but also effectively hinder the sinking trend of the anchor pipe 1 when the anchor pipe 1 has a tendency to automatically sink due to its own weight, thereby effectively improving the stability of the anchor pipe 1 in the soil.

It should be noted that, in order to reduce the hindrance of the barbs on the existing anchor pipe to the process of the anchor pipe drilling into the soil, the barbs on the existing anchor pipe are usually arranged at an acute angle with the anchor pipe, and the acute angle between the barbs and the anchor pipe is toward the tail end of the anchor pipe. However, the existing barbs can reduce the hindrance caused to the anchor pipe, but cannot effectively prevent the anchor from automatically sinking in the soil. Therefore, compared with the barbs on the existing anchor pipe, the external insertion part 10 in the anchor pipe device provided in this embodiment can also effectively prevent the anchor pipe 1 from automatically sinking.

As shown in FIG. 1 , the inner angle of the bend of the slit 3 is an acute angle.

The acute inner angle at the bend of the cut 3 allows the tilted end 101 of the external insertion portion 10 to be a pointed end, and the pointed end can make it easier for the tilted end 101 to be inserted into the soil around the anchor pipe 1, thereby making the tilting process of the tilted end 101 smoother.

There is no restriction on the structural form of the driving component 2. The driving component 2 can adopt an existing rotary opening and closing mechanism, which can drive the blades on the rotating shaft to expand or retract by rotating the rotating shaft. When the blades are expanded, the external insertion part 10 can be driven to tilt up.

In order to enhance the driving force of the driving component 2 and ensure that the external insertion part 10 can be tilted up smoothly in this embodiment, as shown in Figures 2 and 3, the driving component 2 includes a telescopic mechanism 20, and the telescopic mechanism 20 includes a movable end 200. The telescopic mechanism 20 can be telescoped to drive the movable end 200 to move; the movable end 200 can abut against the inner wall of the external insertion part 10, and the movable end 200 is used to push the external insertion part 10 to tilt up in a direction away from the inside of the anchor pipe 1 during the movement.

The telescopic mechanism 20 can be telescoped in the same direction as the radial direction of the anchor pipe 1. At this time, the moving direction of the moving end 200 of the telescopic mechanism 20 is also in the same direction as the radial direction of the anchor pipe 1. Therefore, when the moving end 200 abuts against the inner wall of the external insertion part 10 and the telescopic mechanism 20 is extended, the moving end 200 can drive the external insertion part 10 to move along the radial direction of the anchor pipe 1. Since the connecting end 100 of the external insertion part 10 is still connected to the anchor pipe 1, and the tilting end 101 is separated from the body of the anchor pipe 1 under the action of the slit 3, when the external insertion part 10 is driven by the moving end 200 to move, the external insertion part 10 will tilt in a direction away from the inside of the anchor pipe 1 and be inserted into the soil around the anchor pipe 1.

The telescopic mechanism 20 can be an actuator capable of telescoping, such as an electric push rod, an air cylinder, or an oil cylinder. Since the electric push rod, the air cylinder, and the oil cylinder need to be used with a power source and pipelines, their structures are relatively complex and their costs are also relatively high. Therefore, in order to simplify the structure of the telescopic mechanism 20 and reduce its cost, as shown in FIG. 2 and FIG. 3 , the telescopic mechanism 20 of this embodiment preferably includes a plurality of connecting rods, and the plurality of connecting rods are hinged end to end in sequence to form a ring-shaped connecting rod mechanism. The mobile end 200 is disposed at the hinge between two adjacent connecting rods of the connecting rod mechanism, and the connecting rod mechanism can be deformed under the drive of an external force to drive the mobile end 200 to move.

The connecting rod mechanism can realize the movement process of the movable end 200 by its own deformation. When the connecting rod mechanism is deformed by external force, the movable end 200 on the connecting rod mechanism can move along the radial direction of the anchor pipe 1, thereby driving the external insertion part 10 to tilt up.

In this embodiment, the external force used to drive the deformation of the connecting rod mechanism can be achieved by a push rod. At this time, the connecting rod mechanism can be suspended in the anchor pipe 1 through the support of the suspension rod and can maintain its original shape through elastic parts such as springs connected to the connecting rod mechanism. The push rod can be extended into the anchor pipe 1 and push the connecting rod mechanism to deform after the anchor pipe 1 abuts against the connecting rod mechanism.

It should be noted that, since the connecting rod mechanism can be deformed, the number of connecting rods is at least four. As shown in FIG. 3 , the number of connecting rods in this embodiment is six.

As shown in Figure 3, the connecting rod mechanism is provided with a fixed part 201 and a movable part 202 that can move relative to the fixed part 201; the driving component 2 also includes an axial movable member 21, which is connected to the movable part 202. The axial movable member 21 is used to drive the movable part 202 to move relative to the fixed part 201 along the height direction of the connecting rod mechanism to drive the connecting rod mechanism to deform.

The fixing portion 201 of the connecting rod mechanism can be kept in a fixed position under the support of the aforementioned suspension rod.

The height direction of the connecting rod mechanism can be in the same direction as the axial direction of the anchor tube 1, and the axial moving member 21 can move along the axial direction of the anchor tube 1. When the axial moving member 21 moves along the axial direction of the anchor tube 1, the axial moving member 21 can drive the moving part 202 to move relative to the fixed part 201 along the height direction of the connecting rod mechanism, thereby changing the height of the connecting rod mechanism and deforming the connecting rod mechanism.

When the link mechanism includes six links, the moving portion 202 and the fixing portion 201 of the link mechanism may be respectively disposed on two links that are located opposite to each other among the six links.

As shown in FIG. 2 and FIG. 3 , the driving assembly 2 further includes a fixing member 22 , which is connected to the fixing portion 201 and is used to support the fixing portion 201 to keep it fixed.

The fixing member 22 may be the aforementioned suspension rod. In this case, by holding the fixing member 22 , the position of the fixing portion 201 can be ensured to be fixed.

Furthermore, as shown in Figures 2 and 3, the axial movable member 21 and the fixed member 22 are both rod-shaped, one end of the axial movable member 21 is connected to the movable portion 202, and the other end extends out of the anchor tube 1; one end of the fixed member 22 is connected to the fixed portion 201, and the other end is arranged close to the end of the axial movable member 21 extending out of the anchor tube 1.

When the movable part 202 of the connecting rod mechanism needs to be moved relatively fixedly, the construction worker can use one hand to hold the fixing member 22 to ensure the fixed position of the fixed part 201, and use the other hand to pull the axial movable member 21 to drive the movable part 202 to move relative to the fixed part 201.

When the other end of the axial moving member 21 extends out of the anchor pipe 1 , it is convenient for construction workers to hold the axial moving member 21 , thereby improving the convenience of use of the anchor pipe device.

When the other end of the fixing member 22 is arranged close to the end of the axial moving member 21 extending out of the anchor pipe 1, it is convenient for construction workers to hold the fixing member 22, and the convenience of use of the anchor pipe device can also be improved.

Furthermore, the fixed part 201 and the movable part 202 are arranged at intervals along the height direction of the connecting rod mechanism, and the fixed part 201 is provided with a through hole; the fixed part 22 is tubular, and the end of the fixed part 22 is connected to the through hole of the fixed part 201; the axial movable part 21 is sleeved in the fixed part 22, and the end of the axial movable part 21 close to the movable part 202 passes through the through hole of the fixed part 201 and is connected to the movable part 202.

When the axial moving member 21 is sleeved in the fixing member 22 , the fixing member 22 can guide the axial moving member 21 , thereby improving the stability of the moving process of the axial moving member 21 .

As shown in Figure 3, in order to prevent the fixing member 22 from obstructing the movement of the axial movable member 21, in this embodiment, the length of the fixing member 22 is preferably smaller than the length of the axial movable member 21, and the end of the axial movable member 21 away from the moving part 202 extends out of the fixing member 22.

As shown in FIG. 4 , along the axial direction of the anchor pipe 1 , the pipe body of the anchor pipe 1 is provided with a plurality of external insertion parts 10 , and the raised ends 101 of any group of two adjacent external insertion parts 10 abut against each other.

When the raised ends 101 of any group of two adjacent external insertion parts 10 abut against each other, the output end of the driving component 2 can be at one side of the abutment point of the two raised ends 101. When the driving component 2 drives the external insertion part 10 to be raised in a direction away from the interior of the anchor pipe 1, the output end of the driving component 2 can simultaneously push the two raised ends 101 abutting against each other, so that the two raised ends 101 are both raised in a direction away from the interior of the anchor pipe 1 and inserted into the soil around the anchor pipe 1, thereby improving the construction efficiency of the anchor pipe device.

As shown in FIG. 1 , a plurality of external insertion portions 10 are provided on the anchor pipe 1 along the circumference of the anchor pipe 1 .

When the pipe body of the anchor pipe 1 is provided with a plurality of external insertion parts 10, the anchoring strength between the anchor pipe 1 and the soil can be effectively improved, thereby effectively improving the stability of the anchor pipe 1 in the soil.

When the anchor pipe 1 is provided with a plurality of external insertion parts 10 distributed along its circumference, and along the axial direction of the anchor pipe 1, the raised ends 101 of any group of two adjacent external insertion parts 10 abut against each other, the driving component 2 may include a telescopic mechanism 20 which is a connecting rod mechanism, and the telescopic mechanism 20 may have a plurality of movable ends 200 at the same time, and the plurality of movable ends 200 are arranged in a one-to-one correspondence with the plurality of external insertion parts 10 on the circumference of the anchor pipe 1. When the driving component 2 is used to drive the external insertion parts 10 to be lifted, each movable end 200 may simultaneously drive the two external insertion parts 10 whose lifted ends 101 abut against each other to be lifted at the same time. At this time, the anchor pipe device can not only effectively improve the anchoring effect through the plurality of external insertion parts 10 to achieve the anti-floating and anti-sinking effect, but also can further effectively improve the construction efficiency of the anchor pipe device.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
