The application designs a hydraulic conveying top with an adjustable base support, wherein one end of the base support is connected with a hydraulic component base through a pin shaft assembly, and a universal wheel is arranged at one end of the base support; the design base support sets up to the upper and lower bilayer structure of U type mouth is offered to the side direction with the one end that hydraulic component base is connected, and hydraulic component base is provided with the connecting lug of adaptation U type mouth, and connecting lug stretches into in the U type mouth, connects through the round pin axle subassembly, and arc direction keeps unanimous when every base support installs, and the base support can rotate around the round pin axle subassembly, adjusts the different forms of base support. When rotating along the radian direction of the base support, the furthest end of the base support is retracted inwards, and is in a contracted state relative to the base of the hydraulic component; when rotating along the reverse direction of the radian of the base bracket, the furthest end of the base bracket is outwards opened and is in an unfolding state relative to the base of the hydraulic component; and the rotation angle of the base bracket is flexible. When the base support conveying roof is completely unfolded to pass through a narrow area or placed or lightly loaded, the furthest end of the base support can be adjusted to be folded inwards, so that the base support is in a contracted state, the contraction degree can be determined according to the size of the area, and the base support can be smoothly placed through the narrow area or folded.
However, when the conveying roof moves, the uncontrolled rotation of the base support can increase the difficulty in use, and in order to solve the problem, the application designs that the upper layer of the base support is provided with an upper layer fixing hole, the lower layer of the base support is provided with a lower layer fixing hole, and a limiting hole penetrating up and down is arranged on a connecting lug of the hydraulic component base; the axis of the pin shaft assembly is taken as a rotation center, and the central lines of the upper layer fixing hole, the lower layer fixing hole and the limiting hole are on the same cylindrical surface and are parallel to the axis of the pin shaft assembly; the fixing piece is arranged, when the base bracket rotates around the axis of the pin shaft assembly to be in an unfolding state, the upper layer fixing hole and the limiting hole are communicated, and the fixing piece penetrating through the upper layer fixing hole and the limiting hole is arranged; when the base support is in a contracted state, the lower layer fixing hole and the limiting hole are communicated, and a fixing piece which is in penetrating connection with the lower layer fixing hole and the limiting hole is arranged.
When the base support needs to be adjusted, the fixing piece can be pulled out, so that the base support rotates around the pin shaft assembly, and when the base support reaches the state needing to be adjusted, the fixing piece is inserted between the upper layer fixing hole and the limiting hole on the hydraulic component base or between the lower layer fixing hole and the limiting hole on the hydraulic component base, so that the state of the base support is fixed. When all the base supports are fixedly unfolded, the base support is convenient to use when the rated load is lifted, and the conveying roof is easy to control when moving. When all the base supports are fixedly contracted, the base supports are in an annular contracted state by taking the center of the base of the hydraulic part as the center of a circle, and occupy the smallest space during storage, so that the base supports are favorable for packaging, transportation or light load lifting.

To ensure balance and stability during load movement, at least three base brackets 3 are mounted on the outside of the hydraulic component base 2.

When rotating along the radian direction of the base support 3, the most far end of the base support 3 is retracted inwards, and the base support 3 is in a contracted state relative to the hydraulic component base 2; when rotating along the reverse direction of the radian of the base bracket 3, the most distal end of the base bracket 3 is outwards opened, and the base bracket 3 is in an unfolding state relative to the hydraulic component base 2; and the rotation angle of the base bracket 3 is flexible. When the conveying top base support 3 is completely unfolded to pass through a narrow area or placed or lightly loaded, the most distal end of the partial base support 3 can be adjusted to be retracted inwards, so that the partial base support is in a retracted state, the retraction degree can be determined according to the size of the area, and the conveying top base support can be smoothly placed through the narrow area or folded.
However, when the conveying roof moves, uncontrolled rotation of the base support 3 can increase difficulty in use, in order to solve the problem, the application designs that an upper layer fixing hole 301 is arranged on the upper layer of the base support 3, a lower layer fixing hole 302 is arranged on the lower layer of the base support 3, and a limit hole 201 penetrating up and down is arranged on a connecting lug of the hydraulic component base 2; the axis of the pin shaft assembly 4 is taken as a rotation center, and the central lines of the upper layer fixing hole 302, the lower layer fixing hole 302 and the limiting hole 201 are on the same cylindrical surface and are parallel to the axis of the pin shaft assembly 4; fixing pieces connected with the limiting holes 201 are arranged on the upper fixing holes 301 and the lower fixing holes 302, and in the application, the quick pulling plug pins 5 are adopted as the fixing pieces in the implementation.
