[0022] In municipal construction, masonry projects require a large number of masonry stones, which are large in size and relatively heavy in weight. The masonry project volume is large, and most of the stones are processed in the processing plant set up on site before being transported to the construction site. In order to improve transportation efficiency and reduce labor intensity, people usually use various transportation devices. However, these transportation devices are often complex in structure and difficult to operate, and different equipment is required for stones of different sizes, which greatly increases the difficulty and cost of use. The present device has a simple structure, is easy to make, simple and quick to operate, saves time and effort, is economical and practical, not only has a fast construction speed, is safe and reliable, but also can be repeatedly recycled after the construction is completed, without noise and environmental pollution hazards, has a fast construction speed, high efficiency, and guarantees the construction period.

[0023] The specific structure of the portable stone transport device provided by the present application is described in detail below in conjunction with the accompanying drawings.

[0024] Reference Figure 1 As shown, the portable stone transport device provided by the present application includes a rectangular bracket 3, a wheel 1, a bolt 13, a vertical I-beam 4 and a winch fixing bolt 52; the rectangular bracket 3 is the main structure of the entire device and is the basis for the installation of other components. One end of the two vertical I-beams 4 is symmetrically connected to the center point of the relative side beams at the top of the rectangular bracket 3, and the other end of the two vertical I-beams 4 is connected to a retractable lifting strut 7, and the retractable lifting strut 7 is connected to the top of the vertical I-beam 4. By adjusting the length of the retractable lifting strut 7, the lifting distance can be adjusted. Spokes 12 are installed on the wheel 1, and the spokes 12 are used to protect the wheel rim of the wheel 1, thereby ensuring the stability and safety of the device during movement.

[0025] One end of the telescopic lifting strut 7 is provided with a first fixed pulley 75, and the other end of the telescopic lifting strut 7 is provided with a handrail 73. The handrail 73 is convenient for the operator to hold and control the entire device, and the structure is simple and easy to operate. The telescopic lifting strut 7 also includes a first strut 71, a second strut 74 and a latch 72. The second strut 74 is a hollow structure. The first strut 71 is inserted into the second strut 74. At the same time, a through hole is provided on the first strut 71 and the second strut 74. When the through holes provided on the first strut 71 and the second strut 74 overlap, the latch 72 is inserted into the through hole to connect and fix the two. When multiple through holes are provided, the telescopic adjustment of the telescopic lifting strut 7 can be completed by the cooperation between the through holes at different positions. The bottom of the rectangular bracket 3 is provided with wheels 1, so that the entire device can be moved conveniently. The rectangular bracket 3 is connected to the winch 5 through the winch fixing bolt 52. The winch 5 includes a steel wire rope 53. The movable end of the steel wire rope 53 passes through the first fixed pulley 75 and is connected to a hook 55. The hook 55 is connected to a three-claw lifting device 8 for firmly grabbing stones. The winch 5 includes a winch operating switch 56, which is arranged on the handrail 73. The winch fixing bolt 52 includes a first bolt rod 51. The length of the first bolt rod 51 is greater than the thickness of the steel material constituting the rectangular bracket 3. The first bolt rod 51 passes through the rectangular bracket 3 and is threadedly matched with a matching nut to fix the winch 5 on the rectangular bracket 3.

[0026] When the device is in use, the wire rope 53 on the winch 5 changes direction through the first fixed pulley 75, so that the wire rope 53 can smoothly bypass the device and be connected to the hook 55. The winch is controlled by the winch operation switch 56. When the winch is working, the height of the hook 55 is adjusted by retracting and releasing the wire rope 53, driving the three-claw hoisting device 8 for grabbing stones to complete the lifting in the height direction, and the horizontal movement is completed by adjusting the length of the retractable hoisting strut 7. The wire 54 of the winch 5 passes through the second fixed pulley 43 and is connected to the winch operation switch 56.
