Description

Technical Field

[0001] This utility model belongs to the field of power transmission and transformation engineering technology, specifically involving several new types of spiral anchor construction machinery modified from rotary drilling rigs. Background Technology

[0002] A spiral anchor foundation is an anchoring structure composed of a spiral anchor and a superstructure, primarily utilizing deep soil to resist the forces exerted by the superstructure. This foundation mainly uses steel components, prefabricated in a factory, ensuring stable foundation quality. Mechanized construction reduces construction steps and simplifies the process, significantly reducing or eliminating the use of concrete materials and thus greatly shortening the construction period.

[0003] Currently, research has been conducted on spiral anchor construction equipment in China. One type is modified from excavators, which requires additional modification of the power head and involves complex procedures. In addition, spiral anchor construction machinery modified from excavators needs to screw in the spiral anchor while retracting, requiring a larger working surface and unstable construction load-bearing capacity. The other type is modified from cranes, which requires highly skilled operators and involves complex construction processes, making it unsuitable for large-scale promotion and application. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to meet the various needs in the construction process of spiral anchors, and to provide a new type of spiral anchor construction machinery modified from a rotary drilling rig.

[0021] Figure 6 for Figure 4 Schematic diagram of section 2-2; Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, the new type of spiral anchor construction machinery modified from a rotary drilling rig includes a rotary drilling rig 1, and a drilling rig upright 4 is provided on one side of the rotary drilling rig 1; wherein, a pulley block 5 is provided at the top of the drilling rig upright 4.

[0025] A frame 2 is installed on the rotary drilling rig 1. A winch 3 is installed on the frame 2. A steel strand 6 is wound on the winch 3. The steel strand 6 that comes out of the winch 3 passes through the pulley block 5 and is connected to the power head 7. A spiral anchor 8 is installed below the power head 7.

[0026] During the drilling process of the spiral anchor 8, in order to better screw the spiral anchor 8 into the soil, the machinery should be able to apply a certain pressure to the spiral anchor 8. Based on this, this utility model proposes three pressure application methods, which can be selected according to the actual site conditions in actual engineering.

[0027] The first type of pressurization is gravity pressurization, which means that no additional equipment or facilities are added, and pressurization is achieved through the weight of the spiral anchor 8. Figure 1 As shown. This type of pressurization is the simplest and most convenient, and can be used in soft soil, relatively soft clay, and other similar sites.

[0028] The second type of pressurization is traction-type pressurization, which involves adding a steel strand pulley 10 below the drill rig mast 4. Traction steel strands are wound around the steel strand pulley 10, with one end wound around a traction winch 11 and the other end wound around a power head 7. Rotating the traction winch 11 applies pressure to the power head 7 via the traction steel strands, thereby pressurizing the spiral anchor 8. Figure 2 As shown. This type of pressurization is relatively simple to modify, convenient to pressurize, and can be used in harder surfaces.

[0029] The third type of pressurization is jack-type pressurization, in which a jack 12 is installed on the top of the power head 7. The cylinder of the jack 12 is fixed to the side of the drilling rig upright 4, and the oil pipe of the jack 12 is pressed against the top of the power head 7. In this way, power is applied to the power head through the jack 12, thereby applying pressure to the spiral anchor 8, such as... Figure 3 As shown. This type of pressurization applies the highest pressure, and therefore has a wide range of applications. However, the modification requires specific drilling rig models, and the applied pressure depends on the tonnage of jack 12. Jack 12 can be integrated into the rotary drilling rig 1 or added separately. Since the position of the power head 7 after modification is lower than that of the original drilling rig power head, the modified jack 12 must have sufficient range, and the jack hose should be extended or replaced accordingly.

[0030] like Figure 4 , Figure 5 , Figure 6 As shown, this utility model removes the original drill rod of the drilling rig, retaining only the power head connecting the drill rod, and inserts the rotating component 76 into the power head 7. Specifically, the power head 7 includes a power head body 71, inside which the rotating component 76 is provided. The power of the rotating component 76 comes from the power mechanism built into the rotary drilling rig 1. The rotating component 76 is provided with external teeth 77, which mesh with the internal teeth of the power head. A bottom steel plate 75 is provided at the lower part of the rotating component, and a lower protruding shaft 74 is provided at the lower part of the bottom steel plate 75. The lower protruding shaft 74 is used to connect the spiral anchor 8.

[0031] Better still, a top steel plate 72 is bolted to the power head body 71, and a lifting lug is provided on the top steel plate 72 for connecting the steel strand 6. The upper protruding shaft 73 extends out of the top steel plate 72 for centering and fine-tuning the position of the spiral anchor 8, but may not extend out for ease of construction.

[0032] Furthermore, the power head body 71 is laterally slidably mounted on the drilling rig column 4, which ensures that the power head 7 moves smoothly during operation.

[0033] Furthermore, a hydraulic cylinder is installed on the frame 2, and a support rod 9 is hinged to the output shaft of the hydraulic cylinder. The other end of the support rod 9 is hinged to the drilling rig upright 4. Even better, a diagonal brace is also provided between the hydraulic cylinder body and the drilling rig upright 4, with both ends of the diagonal brace hinged to the hydraulic cylinder body and the drilling rig upright 4, respectively.

[0034] The working principle of this utility model is as follows:

[0035] The rotary drilling rig 1 has a built-in power head 7. When the rotary drilling rig 1 drills, the power head 7 drives the drill rod to rotate and transmits torque. Therefore, when converting the rotary drilling rig 1 into a auger anchor construction machine, it is only necessary to find a way to transmit the torque on the power head 7 to the auger anchor. For this purpose, a rotating component 76 is added inside the power head 7. The power head 7 drives the rotating component 76 to rotate, and the rotating component 76 drives the auger anchor 8 to rotate. A lower protruding shaft 74 is fixed inside the rotating component 76, and the lower end of the lower protruding shaft 74 is used to connect the auger anchor 8. However, in actual projects, sometimes a jack is added above the top steel plate 72 for pressure, so the upper protruding shaft 73 may not need to extend. The specific solution can be determined according to the actual site conditions.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
