Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments.

Referring to fig. 2-6, the embodiment provides a crane supporting leg base plate transportation device, which includes a bottom plate 1, a top plate 2, partition plates 3, connecting rods 4 and casters 5, wherein four partition plates are arranged between the bottom plate 1 and the top plate 2, the bottom plate 1 and the partition plate 3 positioned at the bottommost portion, the adjacent partition plates 3, and the partition plate 3 positioned at the topmost portion and the top plate 2 are welded through the connecting rods 4, the four casters 5 are installed at the bottom of the bottom plate 1, and the bottom plate 1 is provided with storage boxes 13 capable of storing articles such as gloves and tools for workers to load and unload base plates; the middle part of the top surface of the partition plate 3 is provided with three rows of first roller devices, each row of first roller device comprises three first roller frames 6 with the same height, the first roller frames 6 are arranged on the top surface of the partition plate 3 through screws, and the top ends of the first roller frames 6 are provided with first rollers 7 capable of freely rotating; two groups of second roller carriers 8 which are symmetrically distributed along the center line of the partition plate are arranged on the left side and the right side of the top surface of the partition plate 3, the second roller carriers 8 are installed on the top surface of the partition plate 3 through screws, and one end, facing the center line of the partition plate 3, of each second roller carrier 8 is provided with a second roller 9 which can rotate freely; the top surface of the clapboard 3 is provided with first screw holes 10 which are distributed left and right at the positions corresponding to the second roller carrier 8; the front part of the top surface of the partition board 3 is provided with a baffle 11 for blocking the backing plate 16, the bottom of the baffle 11 is mounted on the top surface of the partition board 3 through a screw, and the top surface of the partition board 3 is provided with second screw holes 12 distributed front and back at the position corresponding to the baffle 11. The horizontal height of the second roller 9 is higher than that of the first roller 7 in the first roller device positioned at the rearmost end of the partition board 3, so that the second rollers 9 on the two sides of the partition board 3 can be in contact with the left side and the right side of the inserted cushion board 16

In order to improve the safety during transportation, the height of the first roller frame 6 in the three rows of first roller devices is gradually reduced from the rear end to the front end of the partition board 3, so that the backing plate 16 is obliquely fixed on the partition board 3 in a manner that the backing plate is low in front and high in back, and is not easy to fall off from the rear side of the partition board 3 during transportation.

In order to further improve the safety, a hinge base 14 is arranged on the bottom surface of the rear end of the top plate 2 and the bottom surface of the rear end of the clapboard 3 through screws, a hook 15 is hinged at the bottom of the hinge base 14, when the cushion plate 16 is placed on the clapboard 3, a hand-held rope 17 at the rear end of the cushion plate 16 can be hooked by the hook 15, because the hook 15 is hinged on the hinge base 14, the inserting process of the cushion plate 16 cannot be influenced even if the hook 15 is touched in the process of inserting the cushion plate 16, and the hook 15 also plays a role in blocking when the cushion plate 16 moves like the rear side.

The utility model discloses during the use, at first adjusting roller and 11 positions of baffle: determining the size of the backing plate 16, then moving the two opposite second rollers 9 left and right at intervals, fixing the two opposite second rollers with screws, and adjusting the two opposite second rollers to a position slightly larger than the width of the backing plate 16; the baffle plate 11 is moved back and forth and fixed by screws until the distance from the baffle plate 11 to the first roller 7 closest to the rear side is slightly less than the length of the backing plate 16. During the installation, handheld backing plate 16, portable rope 17 on backing plate 16 is towards the back, stretches into between two second gyro wheels 9 on the baffle 3 earlier backing plate 16 front end, and backing plate 16 bottom contacts with first gyro wheel 7 in proper order until backing plate 16 front end supports at baffle 11 trailing flank, hooks portable rope 17 with couple 15, and the workman can promote the baffle of suitable height and make whole car remove, also can use the shallow. When the portable rope 17 is detached, the portable rope is firstly detached from the hook 15, and then the backing plate 16 is pulled backwards. The backing plate 16 and the roller generate rolling friction in the assembling and disassembling process, and compared with the mutual friction between the backing plates in the prior art, the rolling friction is more labor-saving.
