Embodiment Construction
[0024] Such as Figure 1-Figure 6 As shown, the directional outrigger turning device of the present invention includes a fixed disk 1, a rotating disk 2, a curved plate 3, a first limit block 4 and a second limit block 5, and the fixed disk 1 and the rotating disk 2 are connected by a connecting shaft 6 Together, the rotating disc 2 is connected with two bent plates 3 through four bolts 7, the two bent plates 3 and the boss on the rotating disc 2 form a cylindrical cavity, and the two first limit blocks 4 are symmetrical Fixed on both sides of the fixed plate 1, a second limit block 5 is fixed on the rotating plate 2, and the two first limit blocks 4 and one second limit block 5 are matched so that the rotating plate 2 Reciprocating flip within the range of 180°-190°;
[0025] A locking mechanism 8 is also provided at the edge of the rotating disk 2 .
[0026] The first limiting block 4 is a T-shaped block, and a protrusion is provided at the tail of the T-shaped block, and ...

The invention discloses a directional supporting leg turnover device, belongs to the technical field of turnover supporting legs, and in particular, relates to a turnover device of a truck-mounted crane supporting leg cylinder. For solving the technical problems, the invention provides a supporting leg turnover device capable of realizing directional turnover of a supporting leg cylinder and preventing damage of a hose assembly on the supporting leg cylinder due to artificial operation errors. According to the technical scheme, a fixed disc and a rotating disc are connected together through a connecting shaft, the rotating disc is connected with two bent plates through four bolts, the two bent plates and a lug boss on the rotating disc form a cylindrical cavity, two first limiting blocks are symmetrically fixed on two sides of the fixed disc, a second limiting block is fixed on the rotating disc, and the two first limiting blocks are matched with the second limiting block, so that the rotating disc turns over to and fro in a range of 180 to 190 degrees; and a locking mechanism is arranged on the edge of the rotating disc. The device can be widely applied in the field of truck-mounted cranes.
Description
technical field [0001] The invention relates to an overturning device for directional outriggers, which belongs to the technical field of overturnable outriggers, in particular to an overturning device for an outrigger cylinder of a truck-mounted crane. Background technique [0002] During the driving process of the truck-mounted crane transport vehicle, or during the transportation process of the truck-mounted crane, the outrigger cylinder needs to be inverted, and the outrigger turning device is required at this time. For small truck-mounted cranes, installing an automatic outrigger turning device will increase the cost, so a manual turning outrigger device is usually installed, which is convenient, practical and cheap. The traditional outrigger turning device can be rotated arbitrarily, that is to say, it can be turned 360 degrees clockwise or counterclockwise. However, in actual use, it is often found that the hose assembly on the outrigger cylinder will have different ...
