Further, the bottom plate on set up a plurality of studs, the stud both ends are connected in the otic placode inboard of both sides, the stud is used for the auxiliary stay otic placode, promotes structural strength.
Furthermore, the connecting block is provided with a second shaft hole which is vertical to the first shaft hole in the direction, and the second shaft hole is used for being connected with the supporting leg oil cylinder through an oil cylinder pin shaft.
Furthermore, the bottom plate comprises a flat plate part and bending parts, and the bending parts are arranged at two ends of the flat plate part to increase the flexibility of contact with the ground.
Furthermore, the bottom plate and the ear plate are connected by welding.
Furthermore, the height of the top end of the bent part after bending and the height of the top end of the stud are on the same horizontal plane.
Furthermore, the ear plate is designed to be triangular, one side of the ear plate is fixedly connected to the bottom plate, the top of the ear plate is designed to be circular arc, and the first shaft hole is formed in the top of the ear plate.
Has the advantages that: the utility model adopts the welding integrated supporting leg disc, reduces the number of the assembly parts of the whole machine, has small installation space, has the characteristic of a cross universal joint when being connected with the oil cylinder pin shaft, can adapt to the operation under the working condition of uneven ground, and has higher structural strength, safety and reliability.

Detailed Description
The following describes the embodiments in further detail with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
One embodiment as shown in fig. 1: an lorry-mounted crane integrated supporting foot disc, comprising: the device comprises a bottom plate 1, an ear plate 2, a connecting block 4 and a pin shaft 5; bottom plate 1 on two otic placodes 2 of symmetric connection, two the outside of otic placode 2 corresponds the one end of connecting a round pin axle 5 respectively, two round pin axles 5 are connected through 6 assembly rotations in first shaft hole with the both sides of connecting block 4, connecting block 4 can be around round pin axle 5 clockwise or anticlockwise rotation.
The connecting block 4 is provided with a second shaft hole 7 which is vertical to the first shaft hole 6, and the second shaft hole 7 is connected with the supporting leg oil cylinder through an oil cylinder pin shaft.
The bottom plate 1 comprises a flat plate part and bending parts, and the bending parts are arranged at two ends of the flat plate part.
The height of the top end of the bent part after bending and the height of the top end of the stud 3 are on the same horizontal plane.
The ear plate 2 is designed to be triangular, one side of the ear plate is fixedly connected to the bottom plate 1, the top of the ear plate 2 is designed to be circular arc, and the first shaft hole 6 is formed in the top of the ear plate 2.
As shown in fig. 2-3, the tail end of the supporting leg oil cylinder is connected with the connecting block through an oil cylinder pin shaft, at the moment, the connecting block can rotate along the direction perpendicular to the oil cylinder pin shaft, the stress direction of the supporting leg disc is automatically adjusted according to the actual operation working condition, and the stability and the safety of the lorry-mounted crane during operation are improved; the connecting block end is connected with the ear plate through two round pin axles, and the stabilizer blade disc bottom plate part can rotate along the direction of perpendicular to round pin axle this moment, and under this kind of circumstances, the bottom plate can be according to operating mode adjustment atress directions such as actual ground for the atress form is more firm.
