Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figure 1-8 This is the first embodiment of the present invention, which provides a track-mounted lifting tool, including,

[0031] The main arm 100, the auxiliary arm 200, and the connecting pin 300 are included. The main arm 100 includes a first handle portion 101, a first force-applying portion 102 welded to the end of the first handle portion 101, a first force-generating portion 103 welded to the end of the first force-applying portion 102, and a first engaging portion 104 integrally formed with the first force-applying portion 102.

[0032] The auxiliary lever arm 200 includes a second handle portion 201, a second force-applying portion 202 welded to the second handle portion 201, a second force-generating portion 203 welded to the second force-applying portion 202, and a second engaging portion 204 fixedly connected to the second force-generating portion 203 by bolts. The first engaging portion 104 and the second engaging portion 204 are provided with clamping grooves adapted to the rail G.

[0033] Specifically, the main arm 100 also includes a limiting groove K formed on the surface of the first power generation part 103, the width of which is adapted to the thickness of the second power generation part 203.

[0034] Furthermore, the surfaces of both the first grip portion 101 and the second grip portion 201 are knurled to increase the friction of gripping.

[0035] Furthermore, the main arm 100 and the auxiliary arm 200 are hinged by a connecting pin 300, which includes a pin body 301 and a locking hole 302, used to fix the relative position of the main arm and the auxiliary arm.

[0036] It should be noted that both the main arm 100 and the auxiliary arm 200 are made of high-strength alloy steel, and their surfaces are polished and rust-proofed.

[0037] Preferably, the sum of the cumulative lengths of the first grip portion 101 and the first force-applying portion 102 is greater than the length of the first force-generating portion 103, and the sum of the cumulative lengths of the second grip portion 201 and the second force-applying portion 202 is greater than the length of the second force-generating portion 203, so as to enhance the lever force transmission efficiency.

[0038] During installation, the main arm 100 and the auxiliary arm 200 are hinged together by the connecting pin 300. During operation, two workers hold the first handle part 101 and the second handle part 201 respectively, align them with the rail G and complete the platform movement. The torque is transmitted through the force application part and the force generating part, so that the clamping grooves of the first locking part 104 and the second locking part 204 clamp the rail G. This structure can easily lift the rail and achieve short-distance movement.

[0039] In summary, the double-arm hinge structure significantly reduces the force required for operation by utilizing the lever principle; the cooperation of the first engaging part 104 and the second engaging part 204 ensures that the rail G is firmly clamped and avoids the risk of slippage; the structure is compact and lightweight, making it suitable for operations in complex terrain.
