The utility model discloses the leg of lying prone after two have been installed additional in traditional hoist chassis rear, simple structure installs with low costsly additional, and the dismouting is simple and convenient nimble, hangs after carrying on when or preceding hanging operation when the hoist, and the stability of hoist is better, and what hang is higher, what lie prone is farther.
Description
Technical Field
The utility model relates to a crane chassis technical field specifically is a crane chassis of leg lies prone behind area.
Background
The tyre crane has the main characteristics that the driving cab and the hoisting control cab are integrated into a whole and are formed by evolving a crawler crane (crawler crane), the crawler and the walking bracket of the walking mechanism are changed into a chassis with tyres, the defect that a crawler plate of the crawler crane (crawler crane) damages the road surface is overcome, and the tyre crane belongs to material handling machinery.
The landing leg that can stretch out about driven hoist chassis is installed, carries out left and right sides hoist and mount at the hoist and is that, the stable effectual of hoist chassis, but when the hoist carried out back to hang or hang before, the stability of hoist chassis was relatively poor, takes place the situation of hoist perk easily, has the potential safety hazard.
Disclosure of Invention
For solving traditional hoist and hanging behind or when hanging in the front, the stability of hoist chassis is relatively poor, takes place the situation of hoist perk easily, has the technical problem of potential safety hazard, the utility model provides a lie prone crane chassis of leg behind area.
The crane underframe with the rear lying leg comprises a crane underframe and is characterized in that a lying leg fixing seat is welded at the rear part of the crane underframe, leg lying cylinders are respectively installed on two sides of the lying leg fixing seat, and an articulated shaft II is connected between the two leg lying cylinders and the lying leg fixing seat; articulated shaft I is installed on the hydro-cylinder arm top of the leg hydro-cylinder of lying prone, the hydro-cylinder arm of the leg hydro-cylinder of lying prone installs the leg landing leg of lying prone through articulated shaft I, lie prone the leg fixing base with lie prone and be connected with articulated shaft III between the leg landing leg, lie prone the below of leg landing leg and install the base of a step connecting axle, the leg landing leg of lying prone passes through the base of a step connecting axle is connected with the landing leg base of a step.
Furthermore, the leg-bending supporting leg is a thick-wall square tube.
The utility model has the advantages that:
the utility model discloses the leg of lying prone after two have been installed additional in traditional hoist chassis rear, simple structure installs with low costsly additional, and the dismouting is simple and convenient nimble, hangs after carrying on when or preceding hanging operation when the hoist, and the stability of hoist is better, and what hang is higher, what lie prone is farther.
Drawings
Fig. 1 is a front view of the structure diagram of the present invention;
fig. 2 is a top view of the structural schematic diagram of the present invention.
The components in the figure are labeled as follows: 1. the crane comprises a crane underframe, 2-bending-leg fixing seats, 3-bending-leg oil cylinders, 4-bending-leg supporting legs, 5-base plate connecting shafts, 6-supporting-leg base plates, 7-hinged shafts I, 8-hinged shafts II and 9-hinged shafts III.
Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings:
as shown in the figures, the crane underframe with the rear bending legs comprises a crane underframe 1, a bending leg fixing seat 2 is welded at the rear part of the crane underframe 1, bending leg cylinders 3 are respectively installed at two sides of the bending leg fixing seat 2, and an articulated shaft II8 is connected between the two bending leg cylinders 3 and the bending leg fixing seat 2; articulated shaft I7 is installed on the hydro-cylinder arm top of leg hydro-cylinder 3 of lying prone, and the hydro-cylinder arm of leg hydro-cylinder 3 of lying prone installs leg landing leg 4 of lying prone through articulated shaft I7, lies prone leg fixing base 2 and lies prone and be connected with articulated shaft III9 between the leg landing leg 4, and the below of leg landing leg 4 of lying prone is installed baseboard connecting axle 5, and leg landing leg 4 of lying prone is connected with landing leg baseboard 6 through baseboard connecting axle 5.
The utility model discloses leg landing leg 4 of lying prone is thick wall side's pipe, and below installation landing leg base 6 is got the material portably, and the bearing capacity is strong. The stretching out and the supporting of the leg bending supporting leg 4 can be completed by the leg bending oil cylinder 3, and the operation is convenient and fast. The leg bending support leg 4 is folded and stands behind the crane, and the walking and turning of the crane are not affected. The leg of lying prone behind two of hoist installs additional, makes rear end holding power bigger, more balanced, after the leg of lying prone behind the installation additional, makes the vertical span of hoist increase, when the heavy thing is hung to the back, hangs heavier, farther of lying prone.
The utility model relates to a crane underframe with rear lying legs, which is additionally provided with two rear lying legs at the rear part of the traditional crane underframe, and has simple structure, low additional cost and simple and flexible disassembly and assembly; after the leg of lying prone behind the hoist chassis installs additional, the leg of lying prone behind stretches out support ground, has promoted the support scope of hoist chassis, hangs behind when the hoist or when hanging the operation before, and the stability of hoist is better, and what hang is higher, what lie prone is farther.
The above description is a specific embodiment of the present invention, and all technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
