[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments 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, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] In one embodiment of this utility model, such as Figure 1-4 As shown, this embodiment provides an auxiliary tooling for disassembling and assembling a steel casing, including: at least three support rods 1 and flexible wires 2. The support rods 1 are connected by the flexible wires 2 to form a mesh structure. The upper end of the support rod 1 is provided with an arc-shaped support block 10 adapted to the outer wall of the steel casing 3, and the lower end is provided with a spike end 12. A waist rod 15 is provided in the middle section of the support rod 1. One end of the waist rod 15 is hinged to the support rod 1 through a hinge lug 16, and the other end is provided with a support ring 13. A limiting rope 14 is passed between the support rings 13 of adjacent waist rods 15. One end of the flexible wire 2 is provided with a fixing knot 21, and the other end is provided with a pin 22. Both the support rod 1 and the arc-shaped support block 10 are provided with pin holes 11 that cooperate with the pin 22.

[0029] Specifically, the support rod 1 has an arc-shaped support block 10 at its upper end that fits the outer wall of the steel casing 3, a spiked end 12 at its lower end, and a waist bar 15 in the middle. The inner surface of the arc-shaped support block 10 is provided with a rubber anti-slip layer, the radius of which corresponds to the outer diameter of the steel casing 3, allowing it to fit tightly against the outer wall of the steel casing 3. The rubber anti-slip layer increases friction, preventing the steel casing 3 from sliding during tooling support and improving stability. The spiked end 12 is a detachable structure, including a spiral ground stake and a quick-locking device. The detachable design facilitates the replacement of the appropriate spiked end 12 according to different geological conditions. The spiral ground stake can easily fix the support rod 1 to the ground, and the quick-locking device ensures the rapid installation and removal of the spiked end 12 from the support rod 1.

[0030] One end of the waist rod 15 is hinged to the support rod 1 via a hinge lug 16. The hinge lug 16 is located at the upper-middle part of the support rod 1, allowing the waist rod 15 to rotate flexibly around the hinge lug 16 as a fulcrum. The other end of the waist rod 15 is provided with a support ring 13. The waist rod 15 is composed of a telescopic rod, and its support ring 13 is a rotatable pulley structure. The telescopic rod can adjust the length of the waist rod 15 according to actual needs to adapt to steel casings 3 of different heights. The rotatable pulley structure can reduce friction between the waist rod and the steel casing 3 during assembly and disassembly, making the movement of the steel casing 3 smoother. A limiting rope 14 is threaded between the support rings 13 of adjacent waist rods 15. The limiting rope 14 is an adjustable tension band with ratchet locking mechanisms at both ends. By adjusting the tension of the limiting rope 14, the steel casing 3 can be further fixed. The ratchet locking mechanism ensures that the limiting rope 14 can stably maintain the adjusted tension.

[0031] The flexible wire 2 has a fixing knot 21 at one end and a pin 22 at the other end. Both the support rod 1 and the arc-shaped support block 10 have pin holes 11 that mate with the pin 22. By inserting the pin 22 into the pin hole 11, the flexible wire 2 can be quickly connected and fixed to the support rod 1 and the arc-shaped support block 10. The flexible wire 2 includes vertical cables that connect the support rod 1 longitudinally and horizontal cables that connect adjacent support rods 1 laterally, forming a cross-mesh structure. This structure enhances the overall strength and stability of the tooling, enabling it to better withstand the weight of the steel casing 3 and external forces.

[0032] In another embodiment of this utility model, the number of support rods 1 is 3-6, which are equidistantly distributed along the circumference of the steel casing 3 to form a polygonal support structure. This distribution method enables the tooling to evenly distribute the supporting force on the steel casing 3, improves the stability of the tooling, and adapts to steel casings 3 of different diameters.

[0033] In another embodiment of this utility model, the waist bar 15 is composed of a telescopic rod, and its support ring 13 is a rotatable pulley structure.

[0034] In another embodiment of this utility model, the limiting rope 14 is an adjustable tension band with ratchet locking mechanisms at both ends.

[0035] In another embodiment of this utility model, the inner surface of the arc-shaped support block 10 is provided with a rubber anti-slip layer, and its radius of curvature corresponds to the outer diameter of the steel protective cylinder 3.

[0036] In another embodiment of this utility model, the flexible wire 2 includes a vertical cable that longitudinally connects to the support rod 1 and a horizontal cable that laterally connects to adjacent support rods 1, forming a cross-mesh structure.

[0037] In another embodiment of this utility model, the spike end 12 is a detachable structure, including a spiral ground stake and a quick-locking device.

[0038] In another embodiment of the present invention, the hinged lug 16 is disposed at the upper middle part of the height of the support rod 1.

[0039] In another embodiment of this invention, the flexible wire 2 is made of steel wire rope or high-strength nylon rope. It possesses high strength and wear resistance, ensuring the safety and reliability of the tooling during use.

[0040] In another embodiment of this utility model, a foot pedal ring is further provided in the middle of the support rod 1. The foot pedal ring is connected to the support rod 1 via a movable hinge and can be unfolded to form a temporary working platform. During the disassembly and assembly of the steel casing 3, the operator can stand on the temporary working platform to perform the operation, improving the convenience and safety of the operation.

[0041] The working principle of this utility model is as follows: Installation stage: Insert the spiked end 12 of the support rod 1 into the ground, adjust the position so that the arc-shaped support block 10 is tightly attached to the outer wall of the steel casing 3; connect the flexible wire 2 through the pin 22 to form a mesh constraint; unfold the waist rod 15, insert the limiting rope 14 and lock it with a ratchet to form a ring-shaped reinforcement structure; unfold the foot pedal ring as an operating platform. Disassembly stage: Loosen the ratchet mechanism and the pin 22, retract the waist rod 15 and the flexible wire 2; pull out the support rod 1 and separate the spiked end 12 for transportation.

[0042] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
