Description

Technical Field

[0001] The utility model belongs to the field of chemical product production technology, in particular to a movable crane for lifting and unloading materials. Background Art

[0002] When loading propellant, it needs to be removed from its packaging. Propellant comes in rod-shaped and granular forms. Granular propellant packaging consists of two layers: a square wooden outer box and an inner square iron barrel. After opening the box, the inner barrel must be removed from the wooden box and flipped over to pour the propellant onto the screening platform. Currently, the propellant box is manually pushed into the range of the pneumatic crane, which then lifts the inner barrel out of the outer box. Another person then uses the auxiliary hanging fixture to flip the barrel over, placing it on the screening platform. Finally, the barrel is repeatedly shaken to release the propellant. During use, the crane's range is fixed, limiting its working area. Furthermore, the lifting process is slow and inconvenient. It is labor-intensive and requires the coordination of three people.

[0024] In order to better understand the purpose, structure and function of the present invention, the present invention is described in further detail below with reference to the accompanying drawings.

[0025] like Figure 1-Figure 3 As shown, the movable lifting and unloading crane of the utility model includes a base 1, a lifting rail 2, a lifting cylinder 3, a lifting pulley 4, a lifting wire rope 4, a turning frame 5, a turning cylinder 6, a lifting wire rope 7, a turning wire rope 8, a hook 9, and a turning clamp 10.

[0026] The vehicle body base 1 is a concave flat plate with the concave end as the front end. Wheels are mounted at each corner of the base 1, forming a trolley. The rear wheel is a universal caster, allowing the trolley to move smoothly on the ground. A gate-shaped lifting track 2 is welded to the center of the base 1. A tilting frame 5 is mounted within the groove of the lifting track 2, allowing the tilting frame 5 to move up and down along the lifting track 2. A lifting cylinder 3 is fixed to the non-concave side of the base 1. This hydraulic cylinder is mounted in a forward-facing position, with its base fixed to the flat plate of the base 1. The top of the piston rod of the lifting cylinder 3 is fixed to a crossbeam with pulleys at both ends. Two lifting wire ropes 4 are installed in parallel, one end fixed to the base 1. After passing over the pulley on the piston rod of the lifting cylinder 3, the other end is fixed to the tilting frame 5. The base 1, the pulley driven by the lifting cylinder 3, and the tilting frame 5 form a movable pulley system. When the lifting cylinder 3 is raised, the lifting wire rope 4 drives the tilting frame 5 upward along the lifting track 2, and vice versa. The tilting frame 5 is a Z-shaped bracket with four pulleys mounted on the four corners of the lower plate. The two pulleys at the end are mounted within the lifting track 2, ensuring smooth movement of the tilting frame 5 along the lifting track. A tilting cylinder 6 is fixed to the lower plate of the tilting frame 6. The tilting cylinder 6 is mounted in an inverted position, with its piston rod fixed to the tilting frame 5. Three pulleys are mounted on the upper end of the vertical plate of the tilting frame 5, one on each side and one in the middle. Two pulleys are mounted on either side of the middle of the upper plate of the tilting frame 5, and one pulley is mounted in the middle of the front end. The middle pulley is used to pass the lifting wire rope 7, while the pulleys on both sides are used to pass the tilting wire rope 8. A crossbar is fixed to the front end of the tilting cylinder 6, ensuring that the two wires of the tilting wire rope 8 remain parallel. One end of the lifting wire rope 7 is fixed to the middle of the tilting cylinder crossbar and passes through the vertical plate of the tilting frame 5. It hangs down from the two pulleys in the middle of the upper plate, with a swivel hook 9 at the end. The tilting wire ropes 8 consist of two cables, one end of which is attached to either side of the tilting cylinder's crossbar. They then pass through pulleys on the lower, vertical, and upper plates of the tilting frame, descending to a rotating tilting fixture 10. When the tilting cylinder extends, the lifting wire ropes 7 rise, driving the hook 9 downward; the lifting wire ropes 8 also ascend, driving the tilting fixture upward. When the tilting cylinder retracts, the lifting wire ropes 7 descend, driving the hook 9 upward; the lifting wire ropes 8 also descend, driving the tilting fixture downward. The hook is mounted in the center of the packaging barrel, and the tilting fixture is mounted on one side. The movement of the hook 9 and tilting fixture 10 enables the barrel to be tilted.

[0027] Its working process is:

[0028] Push the crane to the side of the uncapped propellant packaging box. After hooking the hook 9 into the packaging barrel, raise the lifting cylinder 3, using the lifting wire rope 4 to drive the tilting frame 5 up along the lifting track 2. At this point, the tilting cylinder 6 remains stationary, and the packaging barrel rises with the tilting frame. After reaching a certain height, the lifting cylinder 3 stops rising. The crane can be moved, carrying the packaging barrel with it. Once in position, hang the tilting fixture 10 on the upper edge of the packaging barrel, away from the crane. Raise the tilting cylinder 6, and the lifting wire rope 7 extends, shortening the tilting wire rope, causing the packaging barrel to tilt. Repeating this reciprocating tilting motion completes the pouring of the propellant. After the propellant is completely poured, the propellant is returned to its original position, the tilting fixture 10 is removed, the lifting cylinder 3 is retracted, and the packaging barrel is lowered. Finally, the hook 9 is removed, completing the pouring process.

[0029] This embodiment uses two hydraulic cylinders to drive a steel wire rope to raise and tilt the packaging barrel. The combination of the steel wire rope and pulleys allows for rapid lifting of the barrel. The pulley block and steel wire rope are used to repeatedly tilt the cartridge case, emptying the contents completely. The propellant cartridge case can be retrieved and tilted. The system is simple to operate and can be operated by one person, improving efficiency.

[0030] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make several modifications and improvements without departing from the principles of the present invention, and these modifications and improvements should also be considered to fall within the scope of protection of the present invention.
