DETAILED DESCRIPTION

[0025] ​In order to make the technical scheme of the utility model better understood by the skilled in the art, the utility model will be further described in detail below in combination with the drawings.

[0026] As shown in Figures 1-3 A mobile hoisting device, comprising a handcart 1, a vertical rod 2 is rotatably arranged on the handcart 1, a first moving part 3 and a second moving part 4 are slidably arranged on the vertical rod 2, wherein:

[0027] A I-shaped steel beam 10 is rotatably arranged on the first moving part 3, and a fixed pulley block 5 is slidably arranged on the I-shaped steel beam 10.

[0028] A screw rod 6 is rotatably arranged on the first moving part 3, and the screw rod 6 is threadedly connected with a threaded sleeve 7 rotatably arranged on the I-shaped steel beam 10.

[0029] Specifically, the bottom of the handcart 1 is provided with four wheels distributed in diagonal lines, and two of the wheels necessarily have a braking effect.

[0030] Further, the first moving part 3 and the second moving part 4 can be fixed by a quick clamp, or by a pin cooperation, or by other quick-release methods known in the art.

[0031] In the above technology, the handcart 1 is used as a carrier to facilitate the movement of things to be hoisted, and the entire device is designed by assembly, specifically comprising:

[0032] The first moving part 3 and the second moving part 4 can be slidably arranged on the vertical rod 2 to adjust the height of the hoisted articles;

[0033] The I-shaped steel beam 10 and the first moving part 3 are rotatably connected and assembled by the screw rod 6 and the threaded sleeve 7, so as to conveniently adjust the inclination angle of the I-shaped steel beam 10 to adapt to the hoisting requirements, and facilitate disassembly and storage for carrying.

[0034] As a further embodiment of the utility model, as shown in Figure 2 The vertical rod 2 is fixedly provided with a positioning part 21 in contact with the body of the handcart 1, and a positioning pin 22 is inserted into the only hole reserved in the body.

[0035] Specifically, the positioning pin 22 can be removed in the embodiment, so as to manually control the rotation of the vertical rod 2, or the positioning pin 22 can be inserted to keep the I-shaped steel beam 10 in Figure 1 state for use.

[0036] As a further embodiment of this utility model, the upright 2 is provided with a plurality of slots 23 arranged in a linear array, and the first moving part 3 and the second moving part 4 are fixedly installed with a base 8. The base 8 is slidably provided with a latch 81 that can be inserted and assembled with any of the slots 23.

[0037] Furthermore, a lever 82 is rotatably mounted on the base 8, and a gear 821 is fixedly installed on the shaft end of the lever 82. The gear 821 meshes with a toothed plate 811 fixedly installed on the end face of the latch 81.
