[0023] Please refer to Figure 2 , in this embodiment, the guiding structure 2 includes a worm 201 fixed to the outer side of the left output shaft of the double-shaft motor 6 by bolts. A worm gear 202 is meshed with the outer side of the worm 201. Inside the worm gear 202, a connecting rod 203 is fixed, and the upper and lower ends of the connecting rod 203 extend towards one side of the two cross beams 5 respectively. A first gear 204 is fixed to the outer side of the connecting rod 203 and near its top end. A toothed plate 206 meshing with the first gear 204 is arranged on the front of the upper cross beam 5. The toothed plate 206 is fixedly connected to the front of the upper cross beam 5 by bolts. A slide bar 207 is horizontally arranged between the two brackets 1 and on the front of the lower cross beam 5. A sliding block 205 is horizontally slidably connected to the outer side of the slide bar 207, and the sliding block 205 is rotatably connected to the bottom end of the connecting rod 203 by a bearing. On the front of the guide wheel frame platform 3 and near its left end, a placement block rotatably connected to the worm 201 is arranged on the front side. The placement block is fixedly connected to the guide wheel frame platform 3 by bolts.

[0024] It can be understood that by arranging the sliding block 205 and the connecting rod 203, the guide wheel frame platform 3 can slide horizontally more stably. Through the meshing of the first gear 204 and the toothed plate 206, the guide wheel frame platform 3 can slide horizontally automatically, improving the work efficiency.

[0025] Please refer to Figures 3 to 4, in this embodiment, the electric hoist structure 4 includes a chain 401, two grooves 402, two movable rods 403, two second gears 404, four first connecting ropes 405, two connecting handles 406, two second connecting ropes and two hooks 407.

The two grooves 402 are opened on the back side of the guide wheel frame platform 3 and are symmetrically distributed left and right with the central axis of the guide wheel frame platform 3 as the symmetry line. The two movable rods 403 are horizontally arranged between the opposite side walls of the inner cavities of the two grooves 402, and the right ends of both penetrate the right side wall of the inner cavity of the right groove 402 and extend to the right side of the guide wheel frame platform 3. The left and right ends of the two movable rods 403 are rotatably connected between the opposite side walls of the inner cavities of the two grooves 402 through bearings. The two second gears 404 are respectively fixed to the outside of the two movable rods 403 located on the right side of the guide wheel frame platform 3. The four first connecting ropes 405 are divided into two groups, and the upper and lower groups of first connecting ropes 405 are respectively fixed to the outside of the upper and lower movable rods 403. The two connecting handles 406 are respectively fixed to the ends of the left and right groups of first connecting ropes 405 far from the guide wheel frame platform 3. The two second connecting ropes and the two hooks 407 are sequentially arranged at the ends of the two connecting handles 406 far from the guide wheel frame platform 3.

[0026] The upper movable rod 403 meshes with the inside of the chain 401 through a sprocket fixed to its outside and is located in the right groove 402. The two second gears 404 mesh with each other. A plurality of limit rings are arranged on the outside of the two movable rods 403 and are respectively located on the left and right of the two groups of first connecting ropes 405. By arranging a plurality of limit rings, the first connecting ropes 405 can be limited.

[0027] It can be understood that by starting the right output shaft of the dual-axis motor 6, the two movable rods 403 can be rotated in opposite directions, so that the two hooks 407 can rise and fall quickly, improving the stability of cargo transportation.

[0028] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply, and the electrical components mentioned in the text are all conventional known devices. This application will not elaborate too much. The main controller can be a conventional known device such as a computer for control. The control circuit of the main controller can be realized by simple programming by those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And this utility model is mainly used to protect mechanical devices, so this utility model will not explain the control method and circuit connection in detail. At the same time, for the parts not described in detail in this utility model, they are all well-known technologies to those skilled in the art.

[0029] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] The working principle of the above embodiment is as follows:

[0031] When using the gantry crane electric hoist to connect the guide wheel frame to suspend and transport goods, by starting the left output shaft of the double-shaft motor 6, the worm 201 can drive the worm wheel 202 to rotate, and the connecting rod 203 starts to rotate. Since the first gear 204 fixed at the top of the connecting rod 203 meshes with the toothed plate 206, and the bottom end of the connecting rod 203 is rotatably connected to the sliding block 205 through a bearing, the horizontal sliding of the guide wheel frame platform 3 can be more stable. After the guide wheel frame platform 3 moves to the vertical upper side of the goods to be suspended and transported, the left output shaft of the double-shaft motor 6 is turned off, and the right output shaft of the double-shaft motor 6 is started, so that the chain 401 starts to drive the upper movable rod 403 to rotate. Since the two second gears 404 mesh with each other, the two movable rods 403 rotate in opposite directions, so that the two hooks 407 can quickly rise and fall, improving the stability of goods transportation.

[0032] It should be noted that in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
