Description

Technical Field

[0001] This utility model relates to the field of wrenches, specifically to a quick-release wrench. Background Technology

[0002] During field operations of communication base stations and various special vehicles, grounding stakes, as crucial components ensuring the safe operation of equipment, must be firmly driven into the ground to achieve a good grounding effect. However, when the equipment needs to be moved after the operation is completed, the grounding stakes often need to be removed by pulling them out due to the stickiness and friction of the soil. This traditional retrieval method not only consumes a lot of manpower but is also extremely inefficient. In the fast-paced field environment, it seriously affects the rapid transfer and deployment of equipment, thus restricting the overall efficiency of mobile field operations. Utility Model Content

[0003] This utility model aims to provide a quick-release wrench to solve the problems of difficulty and low efficiency in retrieving grounding electrodes under mobile field conditions such as communication field base stations, communication vehicles, and command vehicles, and to achieve quick and easy disassembly of grounding electrodes.

[0004] This utility model provides a quick-release wrench, including a socket, a pin assembly, and a lifting auxiliary assembly.

[0005] Sleeve: The sleeve has an axially penetrating hole, and the inner wall of the hole forms a polygonal clamping surface that matches the grounding pile head. The polygonal clamping surface design ensures a tight fit with the grounding pile head, resulting in uniform force distribution on the grounding pile when torque is applied, effectively preventing slippage, ensuring stability during rotation, and thus smoothly breaking through the adhesive force of the soil on the pile. Preferably, the polygonal clamping surface adopts a regular hexagonal structure. The regular hexagonal structure not only ensures uniform force distribution on the grounding pile when transmitting torque, maximizing the wrench's effectiveness and improving pile extraction efficiency, but also, due to its six-faced structure, allows for the design of threaded holes with the same diameter on each face. These six threaded holes provide flexible options for connecting the wing locking bolt and the extension arm. Operators can freely choose the threaded holes for component connection according to actual operational needs and the environment of the grounding pile, significantly improving the convenience and flexibility of wrench use.

[0006] Pin Assembly: The pin assembly includes at least one telescopic pin mounted on the sleeve. The telescopic pin extends into the sleeve to engage with a groove on the surface of the grounding stake head. This design ensures a reliable connection between the wrench and the grounding stake. When the wrench is pulled upwards, the pin moves the stake upwards, allowing for the removal of the grounding stake. Furthermore, the telescopic pin uses a butterfly locking bolt, threaded onto the sleeve, with a tapered guide head at the end of its thread. By rotating the butterfly locking bolt, the tapered guide head easily extends into the sleeve hole and engages with the groove on the grounding stake head surface using the threaded transmission principle. The butterfly locking bolt design allows for direct hand operation without additional tools, greatly improving the efficiency of connection and disassembly. The tapered guide head provides excellent guidance during insertion, making it easier for the pin to accurately engage with the groove and enhancing the stability of the connection.

[0007] Lifting Auxiliary Component: The lifting auxiliary component includes an extension arm connected to the socket. The extension arm has a long, strip-shaped structure, with its end screwed to the outer wall of the socket. This connection method facilitates the installation and removal of the extension arm. When not in use, it can be disassembled for convenient storage and transportation of the wrench; during use, it also facilitates timely replacement if the extension arm is damaged. In addition, the end of the extension arm is equipped with a non-slip grip section covered with a sponge sleeve. The non-slip grip section effectively prevents the operator's hand from slipping when forcefully pulling out the stake, ensuring operational safety; the soft sponge sleeve significantly improves grip comfort, reduces hand fatigue caused by prolonged operation, and allows the operator to complete the stake extraction work more easily and efficiently. Thanks to the six screw holes provided by the hexagonal structure of the socket, the installation position and number of extension arms can be freely selected to adapt to different operating spaces and force application requirements.

[0008] Beneficial Effects: The quick-release pile wrench of this application transmits torque through the polygonal fit between the socket and the grounding pile head. A reliable connection between the wrench and the pile body is achieved via a pin assembly. A lifting auxiliary component facilitates easy gripping and force application by the operator. It enables rapid rotation of the grounding pile, effectively breaking through soil adhesion and achieving rapid extraction. Compared to traditional brute-force extraction methods, this application significantly improves the efficiency of grounding pile retrieval and reduces labor costs. It is suitable for mobile field scenarios such as communication field base stations and various special vehicles, meeting the needs of rapid equipment transfer and deployment. It boasts advantages such as ease of operation, high practicality, and broad application prospects. Attached Figure Description

[0011] Reference numerals: Sleeve 1, Butterfly locking bolt 2, Extension arm 3. Detailed Implementation

[0012] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] Example 1: Application Scenarios of a Single Extended Arm

[0014] In situations where the work area is confined, the quick-release pile wrench of this application only requires the installation of one extended arm 3. The operator first aligns the hexagonal socket of the sleeve 1 with the head of the grounding pile, ensuring the polygonal clamping surface fits tightly against the pile head. Then, from the six screw holes on the six faces of the sleeve 1, two screw holes are selected, and the wing-shaped locking bolt 2 is screwed in. By rotating the wing-shaped locking bolt 2, the tapered guide head at the end of the screw extends into the socket hole and embeds into the groove on the surface of the grounding pile head, completing a reliable connection between the wrench and the grounding pile. Next, a single long, narrow extended arm 3 is installed in a suitable screw hole on the outer wall of the sleeve 1. The operator holds the non-slip grip section at the end of the extended arm 3 with one hand, applying torque using the extended arm 3 to rotate the grounding pile, gradually breaking down the adhesive force of the soil. As the grounding pile loosens, the operator pulls the extended arm 3 with one hand, and with the help of the pin assembly, successfully pulls the grounding pile out of the confined space.

[0015] Example 2: Two Extended Arms in Conventional Application

[0016] Compared to Embodiment 1, in conventional operation, two elongated extension arms 3 are installed in the screw holes at two opposite corners on the outer wall of the sleeve 1. The operator holds the anti-slip grip sections at the ends of the two extension arms 3 with both hands, applies force symmetrically, and transmits torque through the extension arms 3, causing the grounding stake to rotate rapidly, effectively breaking through the soil resistance. After the grounding stake is fully loosened, the operator pulls the extension arms 3 upwards with both hands to easily pull out the grounding stake.

[0017] Example 3: Four Extended Arms for Heavy-Duty Application

[0018] For special geological conditions, where the grounding pile is driven deep into the ground and the soil has high viscosity, recovery is difficult. In such cases, four extended arms 3 are required. First, the sleeve 1 is accurately fitted onto the head of the grounding pile, using the regular hexagonal sleeve hole to achieve a tight fit. Then, two butterfly locking bolts 2 are screwed into the two screw holes of the sleeve 1, so that the conical guide head is embedded into the groove of the grounding pile head, ensuring a firm connection between the wrench and the grounding pile. Next, four long strip-shaped extended arms 3 are installed in the remaining four screw holes of the sleeve 1. The operators are divided into two groups of two, each group holding the anti-slip grip section at the end of two extended arms 3. Through teamwork, a large torque is applied simultaneously, causing the grounding pile to rotate slowly. As the four extended arms 3 work together, the grounding pile gradually loosens, and the soil viscosity is effectively overcome. Finally, both groups of people pull the extended arms 3 upwards together to pull out the deeply buried and highly resistant grounding pile.
