Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
A quick assembly lift platform for loading and unloading emergency submarines, as shown in figures 1 and 2, includes a lifting device 8, which lifting device 8 may be a scissor lift of the prior art in some embodiments. The lifting device 8 is detachably provided with two first pulley guide rails 1 which are parallel to each other, one end of each first pulley guide rail 1 is connected with a bearing plate 7 which is used for being lapped on a carriage bottom plate, and the other end of each first pulley guide rail 1 is hinged with a second pulley guide rail 2 which is used for being connected with the ground.
Referring to fig. 4, two first connecting blocks 3 parallel to each other are fixed at one end of the second pulley guide rail 2, which is close to the first pulley guide rail 1, a second connecting block 4 positioned between the two first connecting blocks 3 is arranged on the first pulley guide rail 1, connecting holes are coaxially arranged on the first connecting blocks 3 and the second connecting blocks 4, and a second quick-release pin 5 is arranged in the connecting holes.
When the second pulley guide rail 2 is installed, the second pulley guide rail 2 can be fixed by sequentially penetrating the second quick release pin 5 through the connecting hole between the second connecting block 4 and the first connecting block 3 and tightening a nut (not shown in the figure) with the tail end of the second quick release pin 5.
To avoid the problem of the second quick release pin 5 not being screwed to the nut or the strength of the screwing being insufficient, in some embodiments, an end of the first connecting block 3 remote from the second pulley rail 2 extends below the first pulley rail 1 and engages with the first pulley rail 1. After the first pulley guide rail 1 is connected with the second pulley guide rail 2, one end of the first connecting block 3 is fixed with the second pulley guide rail 2, the middle part of the first connecting block is movably arranged on the second quick release pin 5, the other end of the first connecting block is abutted against the lower part of the first pulley guide rail 1, and at the moment, the problem that the second pulley guide rail 2 rotates downwards under the gravity can be limited by the structure, so that the second pulley guide rail 2 is prevented from falling down, and the lifting device 8 can be ensured to descend normally.
Similarly, in other embodiments, this problem may also be solved by extending the end of the second connection block 4 remote from the first pulley rail 1 below the second pulley rail 2 and engaging with the second pulley rail 2.
Because the abutting part between the second connecting block 4 and the first pulley guide rail 1 and the abutting part between the first connecting block 3 and the second pulley guide rail 2 are larger in abutting strength, in some embodiments, a thickened part 6 can be additionally arranged at the bottom of the end, close to the first pulley guide rail 1, of the second pulley guide rail 2, and the thickened part 6 can be used for fixing a steel mechanism through a welded steel structure or through countersunk bolts and the like so as to achieve the purpose of thickening, and the abutting part between the first connecting block 3 and the second connecting block 4 can abut against the thickened part 6, so that the problem that the abutting part between the first connecting block 3 and the second pulley guide rail 2 is deformed is avoided.
The working process and the beneficial effects of the utility model are as follows: firstly lifting the lifting device 8 to the ground from the carriage on the vehicle, then horizontally installing two first pulley guide rails 1 on an upper platform of the lifting device 8, then controlling the lifting device 8 to ascend until the bottom surface of the first pulley guide rails 1 is flush with the carriage bottom plate, and the bearing plate 7 is lapped on the carriage bottom plate, then manually pushing a transfer trolley for loading the assault boat onto the lifting device 8, arranging wheels of the transfer trolley in the first pulley guide rails 1 through the bearing plate 7, transferring the assault boat onto the lifting device 8, and finally controlling the lifting device 8 to descend simultaneously.
