Detailed Embodiments

[0022] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0023] A foldable mobile lifting device, as Figure 1The structure of the present hoisting device after folding is shown, including a vehicle frame 1, a rotating shaft frame 2, a traveling frame 4, a support rod 6, a first telescopic rod 3, a second telescopic rod 7, and a third telescopic rod 5. The first telescopic rod 3, the second telescopic rod 7, and the third telescopic rod 5 are all hydraulic telescopic rods. A fuel tank is configured on the vehicle frame to provide hydraulic oil for the hydraulic telescopic rods. Casters are provided on the vehicle frame 1 to enable it to move freely on the workshop floor. The rotating shaft frame 2 is fixed to the vehicle frame 1, and preferably, the rotating shaft frame 2 is arranged at the center of the vehicle frame 1. The traveling frame 4 and the support rod 6 are both located beside the rotating shaft frame 2. At the same time, the support rod 6 is located on one side of the traveling frame 4. The traveling frame 4 and the support rod 6 are both in a vertical state or an inclined state on a vertical plane. The upper end of the traveling frame 4 is hinged to the top of the rotating shaft frame 2, and the lower part of the support rod 6 is hinged to the lower part of the traveling frame 4. A first telescopic rod 3 is hinged between the rotating shaft frame 2 and the traveling frame 4, and a second telescopic rod 7 is hinged between the support rod 6 and the traveling frame 4. And the second telescopic rod 7 is arranged on the side of the traveling frame 4 facing away from the rotating shaft frame 2. The third telescopic rod 5 is arranged at the upper end of the support rod 6, that is, the end far from the hinged traveling frame 4, and the pushing rod of the third telescopic rod 5 extends and retracts in the length direction of the support rod 6. An electric hoist 8 is provided on the side of the traveling frame 4 facing the rotating shaft frame 2.

[0024] The specific installation structure between the traveling frame 4 and the rotating shaft frame 2 is as follows: A first rotating arm 41 is provided at the upper end of the traveling frame 4. The first rotating arm 41 is hinged to the top of the rotating shaft frame 2. The first telescopic rod 3 is hinged to the lower part of the rotating shaft frame 2, and the pushing rod of the first telescopic rod 3 is hinged to the upper part of the traveling frame 4. When the pushing rod of the first telescopic rod 3 extends, the traveling frame 4 is turned upward around its hinge point with the rotating shaft frame 2, opened, until the traveling frame is horizontal.

[0025] The specific installation structure between the support rod 6 and the traveling frame is as follows: The lower part of the support rod 6 is hinged to the traveling frame 4, and this hinge point is located on the side of the traveling frame 4 facing away from the rotating shaft frame 2. A second rotating arm 61 is provided at the lower part of the support rod 6. The second telescopic rod 7 is hinged to the side of the traveling frame 4 facing away from the rotating shaft frame 2, and the hinge point between the traveling frame 4 and the second telescopic rod 7 is above the hinge point between the traveling frame and the support rod 6. When the pushing rod of the second telescopic rod 7 extends, it is hinged to the second rotating arm 61. When the pushing rod of the second telescopic rod 7 retracts, it drives the support rod 6 to turn outward around its hinge point with the traveling frame 4, and the support rod 6 is opened. This structure can ensure that the electric hoist 8 moves along the traveling frame 4 after the whole of the present utility model is opened, and at the same time ensure that the support rod 6 and the traveling frame 4 turn and open in the same direction. As shown in the drawings of the present utility model, the support rod 6 and the traveling frame 4 both turn clockwise to realize the opening of the present hoisting device, the hoisting of the wire drawing tank, and the transfer.

[0026] The state of the present device when it is opened for hoisting is as Figure 2As shown, the specific process is as follows. First, the device is moved to the hoisting position. The push rod of the first telescopic rod 3 extends, causing the traveling crane frame 4 to turn upward and open around its hinge point with the rotary shaft frame 2 until the traveling crane frame 4 is in a horizontal state. Then, the push rod of the second telescopic rod 7 retracts, causing the support rod 6 to turn outward around its hinge point with the traveling crane frame 4 until the support rod 6 is vertically downward. Immediately afterwards, the push rod of the third telescopic rod 5 extends and tightly presses against the drawing device 13. At this time, the device is in a stable hoisting state. The electric hoist 8 is used to hoist the wire drawing tank 12 to achieve the hoisting and transfer of the wire drawing tank 12.

[0027] In the present utility model, a pressing head 51 is provided at the telescopic end of the third telescopic rod 5 to improve the stability when the second telescopic rod 5 presses against the drawing device 13.
