Description

Technical Field

[0001] The utility model relates to the technical field of engineering instruments, in particular to a stabilizing device for a spiral anchor. Background Art

[0002] With the development of society, machinery plays an increasingly important role in people's daily life and production. Due to the convenience and precision of machinery, a lot of manpower and financial resources are saved. As a result, lifting equipment used to lift large machinery has also developed and become an indispensable component. Crane refers to a multi-action lifting machinery that vertically lifts and horizontally transports heavy objects within a certain range. It is also called overhead crane, overhead crane, and crane. Some lifting equipment has the working characteristics of intermittent movement, that is, the corresponding mechanisms of material collection, transportation, unloading and other actions work alternately in a working cycle. The development and use of cranes in the market are becoming more and more extensive. Because there are often some accidents when lifting and driving with loads without outriggers, the driving speed is also faster than crawler cranes (crawler cranes); the operation is stable, the lifting weight is large, and it can be lifted and walked within a specific range, but it must be ensured that the road is flat and solid, the tire pressure meets the requirements, and the lifting distance from the ground must not exceed 50CM; it is forbidden to travel long distances with loads.

[0003] Before the crane is lifted, it is necessary to use anchoring devices around the crane to reinforce the crane to prevent the crane from falling and improve stability. However, the traditional screw-in anchoring devices for cranes on the market are not well optimized in structure and reasonable in design.

[0004] In the prior art, a Chinese patent with a publication number of CN210393475U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a screw-in anchoring device for a crane, comprising an anchor box, an entrance and an exit are provided through the middle of the bottom of the anchor box, a mounting plate is fixedly connected to the top of the anchor box, a second rotating motor is fixedly installed on one side of the top of the inner wall of the anchor box, and a threaded rod is fixedly installed at the output end of the second rotating motor. The screw-in anchoring device for the crane, through the coordinated use of the entrance and exit, the limit slide bar, the movable plate, the main shaft, the first rotating motor, the mounting plate, the second rotating motor, the transmission shaft, the ground anchor mechanism, the spiral ground anchor rod, the threaded rod, the first gear and the second gear, the spiral ground anchor rod is screwed into the ground, thereby reinforcing the crane, improving its stability, and helping to prevent the crane from tilting. At the same time, multiple spiral ground anchor rods are set, which helps to improve the stability of the crane, and one drive simultaneously drives multiple spiral ground anchor rods to rotate, which helps to reduce manufacturing costs.

[0005] Although the prior art can screw the spiral ground anchor into the ground through various component structures, thereby reinforcing the crane and improving its stability, after the spiral ground anchor is drilled into the soil, its end is easily affected by hard objects such as soil and rocks, which can easily cause the spiral ground anchor to be deflected by force, affecting the stability of its connection with the mounting seat. In the long run, this will accelerate the wear of the spiral ground anchor and affect its service life. Utility Model Content

[0027] The present invention is further described in detail below in conjunction with the embodiments:

[0028] Example 1

[0029] like Figure 1-5 As shown, the utility model provides a stabilizing device for a spiral anchor, comprising an anchor box 1, a driving assembly 2, a spiral anchor rod 3, a movable plate 6 and an anchor rod stabilizing assembly 4, wherein the anchor rod stabilizing assembly 4 comprises a first positioning ring plate 7 and a second positioning ring plate 8 located above the spiral anchor rod 3, and the first positioning ring plate 7, the second positioning ring plate 8, the reinforcement column 9, the reinforcement built-in rod 11 and the positioning base plate 5 are used in coordination, so that the spiral anchor rod 3 can be guided and limited by the bottom and top outer walls when moving downward to drill the ground, thereby ensuring that the spiral anchor rod 3 can always maintain a state perpendicular to the bottom surface of the movable plate 6 to move downward, avoiding the problem of offset and misalignment at the connection with the movable plate 6 due to external force during the drilling process, thereby ensuring the operating stability of the spiral anchor rod 3.

[0030] The inner wall of the spiral anchor 3 is fixedly plugged with a reinforcing built-in rod 11 for guiding and limiting it. The top of the reinforced built-in rod 11 is movably connected with the second positioning ring plate 8 and the first positioning ring plate 7 in sequence. The surfaces of the first positioning ring plate 7 and the second positioning ring plate 8 are provided with mounting grooves. The inner wall of the mounting groove is fixedly connected with an axial ring 10. The axial ring 10 sleeved on the outer wall of the reinforced built-in rod 11 ensures the smoothness of the downward movement of the reinforced built-in rod 11. At the same time, the reinforced inner ring 14 sleeved on the outer wall of the bottom end of the reinforced built-in rod 11 is used to improve the firmness of the connection between it and the spiral anchor 3, improve the overall structural strength of the spiral anchor 3, and further extend its service life.
