Description

Technical Field

[0001] This utility model relates to a ground anchor device for power engineering. Background Technology

[0002] During the tower erection and line stringing construction of power transmission lines, ground anchor devices are mainly used for anchoring guy wires or conductors. When in use, ground anchor devices need to be driven deep into the soil. Most existing ground anchor devices use ground anchor rods, which have a simple structure. Simply using the external spiral blades of the ground anchor rod for driving it into the soil is insufficient to improve the stability between the ground anchor device and the soil. In soft soil, it is difficult to guarantee the stability of the ground anchor device within the soil, which may affect the guy wire work in power engineering.

[0003] Therefore, it is necessary to provide a ground anchor device for power engineering to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a ground anchor device for power engineering, so as to solve the problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A ground anchor device for power engineering includes a fixed cylinder, a spiral blade fixedly sleeved on the outer wall of the fixed cylinder, a drill bit provided at the bottom of the fixed cylinder, a rotating rod rotatably installed inside the fixed cylinder, a cam fixedly sleeved on the outer wall of the rotating rod, a plurality of equally spaced insert rods slidingly passing through both the front and rear ends of the fixed cylinder, one end of the insert rod contacting the cam, a locking assembly connecting the top of the rotating rod through the fixed cylinder, and a connecting frame movably installed on the top of the outer wall of the fixed cylinder, with a pull wire ring provided on the top of the connecting frame.

[0007] Preferably, one end of the insertion rod is provided with a contact portion, which is hemispherical and contacts the cam.

[0008] Preferably, limit blocks are provided on both sides of the outer wall of the insertion rod, and the limit blocks are located inside the fixed cylinder.

[0009] Preferably, both sides of the connecting frame are threaded with connecting bolts, and the connecting frame is connected to the fixed cylinder through the connecting bolts.

[0010] Preferably, the locking assembly includes a rotating plate, locking bolts, and locking holes. The rotating plate is connected to the top of the rotating rod through the fixed cylinder. Locking bolts are threaded on both sides of the rotating plate. Locking holes are provided on both the front and rear sides of the top of the fixed cylinder, and one end of the locking bolt can be inserted into the locking hole.

[0011] Preferably, the top of the rotating plate is provided with an installation sleeve, and the top of the installation sleeve is provided with an insertion groove, the insertion groove having a hexagonal cross-section.

[0012] The beneficial effects of this utility model are as follows: The fixed cylinder is placed vertically on the ground to be driven. An external driving device drives the pull ring to rotate, which in turn drives the fixed cylinder to rotate. Through the spiral blades and drill bit, the fixed cylinder can be driven into the soil more effectively. By rotating the connecting bolt, the connection between the connecting frame and the fixed cylinder is released. At this time, the external rotating device drives the installation sleeve to rotate, which in turn drives the rotating plate and the rotating rod at its bottom to rotate. This causes the cam to rotate, thereby driving the two insertion rods on both sides to move away from each other. By using the two insertion rods at different vertical positions, it is possible to insert and fix them at different soil depths to improve the firmness of the fixed cylinder in the soil. Then, the locking bolt is rotated to insert it into the corresponding locking hole to complete the limiting process of the rotating plate. The connecting bolt is then used to reconnect the connecting frame and the fixed cylinder. The pull ring is located above the ground for use in power engineering for pulling wires or conductors.

[0022] See Figures 1 to 7 The diagram shows a ground anchor device for power engineering, comprising a fixed cylinder 1, a spiral blade 2 fixedly sleeved on the outer wall of the fixed cylinder 1, a drill bit 3 provided at the bottom of the fixed cylinder 1, a rotating rod 4 rotatably installed inside the fixed cylinder 1, a cam 5 fixedly sleeved on the outer wall of the rotating rod 4, a plurality of equally spaced insert rods 6 slidingly passing through both the front and rear ends of the fixed cylinder 1, one end of the insert rod 6 contacting the cam 5, a locking assembly 7 connecting the top of the rotating rod 4 through the fixed cylinder 1, a connecting frame 8 movably installed on the top of the outer wall of the fixed cylinder 1, and a pull wire ring 9 provided on the top of the connecting frame 8.

[0023] Furthermore, one end of the insertion rod 6 is provided with a contact portion 10, which is hemispherical and contacts the cam 5.

[0024] The contact portion 10 is hemispherical to reduce the friction between the insert rod 6 and the cam 5.

[0025] Furthermore, limit blocks 11 are provided on both sides of the outer wall of the insertion rod 6, and the limit blocks 11 are located inside the fixed cylinder 1.

[0026] The limiting blocks 11 on both sides prevent the insertion rod 6 from completely disengaging from the fixed cylinder 1.

[0027] Furthermore, both sides of the connecting frame 8 are threaded with connecting bolts 12, and the connecting frame 8 is connected to the fixed cylinder 1 through the connecting bolts 12.

[0028] The connecting bolts 12 are used to fix the connecting frame 8 to the top of the fixed cylinder 1.

[0029] Furthermore, the locking assembly 7 includes a rotating plate 71, locking bolts 72, and locking holes 73. The top of the rotating rod 4 passes through the fixed cylinder 1 and is connected to the rotating plate 71. Locking bolts 72 are threaded on both sides of the rotating plate 71. Locking holes 73 are provided on both the front and rear sides of the top of the fixed cylinder 1. The locking holes 73 allow one end of the locking bolt 72 to be inserted.

[0030] The rotating plate 71 and the rotating rod 4 at its bottom are rotated, causing the cam 5 to rotate 90 degrees, thereby causing the two insert rods 6 on both sides to move away from each other. Then, the locking bolt 72 is rotated to insert it into the corresponding locking hole 73, thus completing the limiting process of the rotating plate 71.

[0031] Furthermore, the top of the rotating plate 71 is provided with an installation sleeve 13, and the top of the installation sleeve 13 is provided with an insertion groove 14, the insertion groove 14 having a hexagonal cross-section.

[0032] An external motor drive device is used to insert its output end into the insertion slot 14, thereby better driving the mounting sleeve 13 and the rotating plate 71 at its bottom to rotate.

[0033] In use, the fixed cylinder 1 is placed vertically on the ground to be driven. An external driving device drives the pull ring 9 to rotate, which in turn drives the fixed cylinder 1 to rotate. The spiral blade 2 and the drill bit 3 help the fixed cylinder 1 to be driven into the soil more effectively. By rotating the connecting bolt 12, the connection between the connecting frame 8 and the fixed cylinder 1 is released. At this time, the external rotating device drives the mounting sleeve 13 to rotate, which in turn drives the rotating plate 71 and the rotating rod 4 at its bottom to rotate, causing the cam 5 to rotate 90 degrees. This causes the two insert rods 6 on both sides to move away from each other. The two insert rods 6 at different vertical positions are used to insert and fix the cylinder 1 at different soil depths to improve its firmness inside the soil. Then, the locking bolt 72 is rotated to insert it into the corresponding locking hole 73 to complete the limiting process of the rotating plate 71. The connecting bolt 12 is then used to reconnect the connecting frame 8 and the fixed cylinder 1. The pull ring 9 is located above the ground for use as a pull wire or conductor in power engineering.

[0034] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
