[0027] Embodiment 1, below is combined with the attached Figure 1-3 This application is described in further detail.

[0028] The embodiment of the present application discloses a portable handheld device for railway operations.

[0029] Portable handheld devices for railway operations, including;

[0030] The railway working frame 100, two pulleys A300 and two pulleys B500 are located at the bottom of the railway working frame 100, there is a spacing between the two pulleys A300, the top of the pulley A300 is installed on the bottom of the railway working frame 100 by screws, there is a spacing between the two pulleys B500, the top of the pulley B500 is installed on the side of the railway working frame 100 by screws, the bottom of the railway working frame 100 has a welded and fixed support frame 200, the top of the support frame 200 has an embedded anti-skid pad 201, the top of the anti-skid pad 201 is convex, when in use, the electrical equipment needed for railway operation is placed on the support frame 200, when the electrical equipment is placed on the support frame 200, the anti-skid pad 201 can play an anti-skid role, which can prevent the electrical equipment from sliding and rolling on the support frame 200, and the railway A handle 102 is provided on the top of the working frame 100, and both ends of the handle 102 are welded and fixed to the railway working frame 100. An anti-skid sleeve is provided on the outer side of the handle 102, and a plurality of anti-skid grooves are provided on the anti-skid sleeve. Then, the handle 102 is pressed downward to rotate the railway working frame 100 around the pulley A300, and the electrical equipment on the support frame 200 is tilted up through the lever principle. As the railway working frame 100 rotates, the pulley B500 contacts the ground, and the railway working frame 100 is supported at four points through two pulleys A300 and two pulleys B500, so that the railway working frame 100 stands stably on the ground. By pushing the handle 102, the railway working frame 100 can be moved by rotating the pulleys A300 and B500, thereby transporting the electrical equipment and workpieces required for railway operations.

[0031] See also Figure 1-3An auxiliary power assembly is installed on the railway working frame 100, and the auxiliary power assembly includes a fixed frame 400, a dual-axis drive motor A401, a support rod 402, and a dual-axis drive motor B501; the fixed frame 400 is located between the two pulleys A300, and the top of the fixed frame 400 is welded and fixed to the bottom of the railway working frame 100, and one end of the fixed frame 400 away from the railway working frame 100 is buckled on the outside of the dual-axis drive motor A401, and the dual-axis drive motor A401 has two output shafts at both ends. The two output shafts are inserted into the two support rods 402 and fixed by bolts. The dual-axis drive motor A401 and the pulley A300 are coaxial. The diameter of the support rod 402 is larger than the diameter of the pulley A300. Therefore, when the pulley A300 is trapped in a pit or needs to cross a higher obstacle, the dual-axis drive motor A401 drives the support rods 402 at both ends to rotate at a low speed. The torque generated by the dual-axis drive motor A401 drives the support rods 402 to tilt the railway working frame 100, thereby assisting the pulley A300 to cross the obstacle.

[0032] See also Figure 2 The dual-axis drive motor B501 is located between the two pulleys B500. Two output shafts are provided at both ends of the dual-axis drive motor B501. The two output shafts at both ends of the dual-axis drive motor B501 are connected to the two pulleys B500. When the pulley A300 and the pulley B500 contact the ground synchronously, the dual-axis drive motor B501 drives the pulley B500 to rotate, thereby assisting manpower in driving the railway working frame 100, thereby reducing the burden on railway construction personnel.

[0033] See also Figure 3 The bottom of the fixing frame 400 is in a 'U' shape. The bottom of the fixing frame 400 is wrapped around the outside of the dual-axis drive motor A401 and fixed by bolts. When the dual-axis drive motor A401 needs to be maintained, it can be disassembled to facilitate later maintenance.

[0034] See also Figure 3 There are multiple reinforcement rods 101 near the top of the railway working frame 100, and there is a distance between every two reinforcement rods 101. Both ends of the reinforcement rods 101 are welded and fixed to the railway working frame 100. Welding multiple reinforcement rods 101 can reduce the overall weight of the railway working frame 100.

[0035] See also Figure 1-2The support frame 200 has a symmetrical support leg B203 at one end away from the railway working frame 100. The support leg B203 and the support frame 200 are an integrated structure. The support leg B203 is formed by bending. When loading and unloading, the support leg B203 is supported on the ground to provide support. There is a support leg A202 on the outside of the support leg B203. One end of the support leg A202 is welded and fixed to the support leg B203. The support leg A202 is inclined. The support leg A202 and the support frame 200 form a slope after being combined, which makes loading and unloading more convenient.

[0036] Working principle: When in use, place the electrical equipment needed for railway operation on the support frame 200, then press the handle 102 downward to make the railway operation frame 100 rotate around the pulley A300, and lift the electrical equipment on the support frame 200 through the lever principle. As the railway operation frame 100 rotates, the pulley B500 contacts the ground, and the railway operation frame 100 is supported at four points by two pulleys A300 and two pulleys B500, so that the railway operation frame 100 can stand stably. On the ground, pushing the handle 102 can move the railway work frame 100 through the pulley A300 and the pulley B500, so as to transport electrical equipment and workpieces required for railway operations. When the pulley A300 is stuck in a pit or needs to cross a higher obstacle, the dual-axis drive motor A401 drives the support rods 402 at both ends to rotate at a low speed. The torque generated by the dual-axis drive motor A401 drives the support rods 402 to lift the railway work frame 100, thereby assisting the pulley A300 to cross the obstacle.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
