Fig. 2 is a left side view of the present utility model.
In the figure: the crawler belt type hydraulic lifting platform comprises a trolley body 1, a crawler belt running system 2, hydraulic lifting support legs 3, a fixed platform 4, a first lifting platform 5, a first lifting hydraulic cylinder 6, a second lifting platform 7, a second lifting hydraulic cylinder 8, a lateral overturning platform 9, a connecting rod 10, a lateral hydraulic cylinder 11, a lateral pushing-out platform 12, a tunnel face pushing-out platform 13 and a crawling ladder 14.
Detailed Description
As shown in fig. 1, the novel movable trolley for supporting the tunnel charge comprises a trolley main body 1, wherein a crawler belt traveling system 2 is arranged at the left and right sides of the bottom end of the trolley main body, and the crawler belt traveling system 2 can realize self-traveling of the device on uneven roads in a tunnel. The hydraulic lifting support legs 3 are arranged at the bottoms of the trolley main bodies 1 in front of and behind the crawler traveling system 2, and the hydraulic lifting support legs 3 extend out after reaching a destination, so that a stable supporting effect can be achieved.
A first lifting platform 5 is arranged right above the two groups of fixed platforms 4 of the trolley main body 1, and the first lifting platform 5 is driven to lift by a first lifting hydraulic cylinder 6. The cylinder body of the first lifting hydraulic cylinder 6 is mounted on the column of the trolley body 1. A second lifting platform 7 is arranged right below the two groups of fixed platforms 4 of the trolley main body 1, and the second lifting platform 7 is driven to lift through a second lifting hydraulic cylinder 8. The second jacking hydraulic cylinder 8 passes through the hole of the fixed platform 4 at the lower end and is mounted on the bottom surface of the fixed platform 4 at the upper end. The first lifting platform 5 and the second lifting platform 7 are adjusted to a proper height through corresponding hydraulic cylinders, so that the operation is convenient.
In addition, a plurality of groups of lateral overturning platforms 9 are hinged on the left and right outer sides of the trolley main body 1, and the left and right sides of each group of lateral overturning platforms 9 are hinged through a connecting rod 10, so that linkage can be realized. Each side is hinged with a group of lateral hydraulic cylinders 11 at the lower end of one or two groups of lateral overturning platforms 9, and when the lateral hydraulic cylinders 11 extend out, the groups of lateral overturning platforms 9 can be unfolded horizontally. In fig. 1, only one lateral hydraulic cylinder 11 is hinged to the lower part of the left and right lateral overturning platforms 9 at the uppermost end. When the power is insufficient to push the three sets of lateral overturning platforms 9 at the same time, a lateral hydraulic oil cylinder 11 (not shown in fig. 1) can be hinged at the lower end of the middle lateral overturning platform 9 on each side, and the three sets of lateral overturning platforms 9 on each side can be unfolded or folded through the two sets of lateral hydraulic oil cylinders 11 arranged on each side.
