Description

Technical Field

[0001] This utility model relates to the technical field of fire-fighting steel bar pulling device, specifically a fire-fighting steel bar anchor point recovery device. Background Technology

[0002] In rescue situations where no strong anchor points are available, especially in wilderness environments, steel stake ground anchoring systems are a better option for facilitating rescue operations. A robust anchoring system is established using 1.2m long, 25mm diameter steel stakes. The strength of the anchoring system depends on the soil type, the number of stakes used, and the depth to which the stakes are driven into the soil. In solid soil, a system with three stakes connected in series in a straight line can achieve a strength of up to 36KN. However, once the stakes are inserted into the soil, they are difficult to pull out, requiring considerable time and effort to remove after the rescue, increasing the workload of firefighters.

[0017] 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.

[0018] In the description of the embodiments of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. 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.

[0019] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance. The use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be perfectly horizontal, but can be slightly tilted.

[0020] In the description of the embodiments of this utility model, the terms "multiple" or "several" refer to at least two.

[0021] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] This embodiment is combined with the appendix Figures 1 to 3 This paper provides a detailed description of a fire-fighting steel rod anchor point recovery device.

[0023] This embodiment provides a fire-fighting steel rod anchor point recovery device, including a straight handle 1, with a rotatable U-shaped clamp 2 at the front end of the straight handle 1, the opening direction of the U-shaped clamp 2 being perpendicular to the straight handle 1;

[0024] It also includes a support rod 3, the top of which is provided with a rotatable sleeve 4, the sleeve 4 is fitted onto the straight rod 1 and fastened by a T-shaped screw 5, and the bottom of the support rod 3 is provided with a base 6.

[0025] The base 6 includes a ball groove 61 and a base plate 62 fixed together. The bottom end of the support rod 3 is provided with a ball head 7, which rotates within the ball groove 61. The ball groove 61 covers most of the ball head 7.

[0026] The sleeve 4 is provided with two threaded T-shaped screws 5.

[0027] The rotating surfaces of the U-shaped clip 2 and the sleeve 4 coincide.

[0028] In practice, fire-fighting steel rods are usually inserted at an angle into the ground. When they need to be pulled out, place the base 6 near the anchor point of the steel rod (first loosen the T-bolt 5), then extend the front end of the straight handle 1 towards the steel rod, use the U-shaped clamp 2 to hold the steel rod in place, and then tighten the T-bolt 5. At this point, the state is as follows: Figure 3 Then, hold the rear end of the straight handle 1 and press down using a lever-like motion (during the pressing process, the straight handle 1 rotates around the support point, and the front end rotates with the U-shaped clamp 2; if the terrain is uneven, the ball head 7 will rotate in the ball groove 61). The U-shaped clamp 2 will then lock the steel rod and pull it out of the ground.

[0029] The U-shaped clip 2 can also be hooked into the hole of the underground fire hydrant cover, and then the lever principle is used to press down the straight handle 1 to open the rusted underground fire hydrant cover.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the actual scope of protection is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this invention should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the scope of the claims.
