Abstract
The utility model discloses a lorry crane gravity hydraulic pressure inner equilibrium hanging flower basket comprises mechanical part and hydraulic system, and wherein mechanical part includes that boom assembly and hanging flower basket assembly constitute, and the hanging flower basket assembly passes through the swing arm and installs on boom assembly, but hydraulic system is including balanced hydro -cylinder, the trigeminy of surging piece, one -way adjustable throttle valve, high pressure ball valve, oil filler hole check valve. The utility model discloses the structure is slim and graceful simple, and the safety and stability performance is high, thereby adopts the angle of swing arm to change the centrobaric change of modifier, and is balanced through adjusting hydraulic system internal pressure, realizes aerial working platform's balance.
Description
Technical field
This utility model is related to the aerial work platform of lorry-mounted crane, specifically a kind of lorry-mounted crane gravity liquid
Pressure inner equilibrium hanging basket.
Background technology
At present, truck with loading crane on the market only has folding arm crane can pass through the behaviour of hydraulic control aerial work platform
Make, but its complex structure high cost.Straight-arm lorry-mounted crane is all using mechanical control aerial work platform, and its operation is multiple
Miscellaneous, safety and stability performance is poor.
Content of the invention
This utility model is directed to the problems referred to above, provides a kind of lorry-mounted crane gravity hydraulic inner equilibrium hanging basket.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of lorry-mounted crane gravity hydraulic inner equilibrium hanging basket it is characterised in that being made up of mechanical part and hydraulic system,
Wherein mechanical part includes boom assembly and hanging basket assembly composition, and hanging basket assembly is arranged on boom assembly by swing arm；Hydraulic pressure
System includes balancing cylinder, the three linked piece that surges, 2 unidirectional adjustable throttlings, high-pressure ball valve, oil filler check valves, balancing cylinder
The hydraulic fluid port in left side is connected with the three linked piece oil-in that surges, and the three linked piece oil-out that surges is connected with unidirectional adjustable throttling, unidirectional can
Flow regulating valve is connected with high-pressure ball valve, and the high-pressure ball valve other end is connected with another unidirectional adjustable throttling, this unidirectional scalable
Stream valve is connected with the hydraulic fluid port on the right of balancing cylinder, is welded with oil filler check valve on the pipeline that the two connects.
Compared with prior art, the utility model has the advantage of: this apparatus structure is merrily and lightheartedly simple, safety and stability performance
Height, using swing arm angle change thus changing the change of device center of gravity, by adjust hydraulic system internal pressure balance, realize
The balance of aerial work platform.

Specific embodiment
Below in conjunction with the accompanying drawings enforcement of the present utility model is described below:
Lorry-mounted crane gravity hydraulic inner equilibrium hanging basket is made up of mechanical part and hydraulic system, as shown in figure 1, wherein machine
Tool part includes boom assembly 6 and hanging basket assembly 8 forms, and hanging basket assembly 8 is arranged on boom assembly 6 by swing arm 7.As Fig. 2
Shown, hydraulic system includes balancing cylinder 1, surge three linked piece 2,2 unidirectional adjustable throttlings 3, high-pressure ball valve 4, oil filler lists
To valve 5, the hydraulic fluid port in balancing cylinder 1 left side is connected with three linked piece 2 oil-in that surges, and three linked piece 2 oil-out that surges is connected with unidirectional
Adjustable throttling 3, unidirectional adjustable throttling 3 is connected with high-pressure ball valve 4, high-pressure ball valve 4 other end and another unidirectional scalable
Stream valve 3 connects, and this unidirectional adjustable throttling 3 is connected with the hydraulic fluid port on balancing cylinder 1 the right, is welded with the pipeline that the two connects
Oil filler check valve 5.
First pass through oil filler check valve 5 and fill hydraulic oil to balancing cylinder 1, when suspension arm of lorry-mounted crane assembly 6 is slow upwards
When lifting slowly, because hanging basket assembly 8 is bucket structure, therefore center of gravity also can change, and now the pressure of hydraulic system is located
In unbalanced state, open high-pressure ball valve 4, make hydraulic system be in opening.Slowly adjust the control of unidirectional adjustable throttling 3
Handle processed, because the sectional area in balancing cylinder 1 about two chamber is identical, oil cylinder 1 is moved by out-of-balance force, that is, close hydraulic pressure
At system mesohigh at low pressure fuel feeding, the external force of gravity event resolves when hanging basket 8 level, oil cylinder 1 external force event resolves, balance
Oil cylinder 1 both sides pressure balance, now closing high-pressure ball valve 4, just realizing the balanced adjustment of aerial work platform, thus realizing safety
Job requirements.When boom assembly 6 declines, the center of gravity direction of hanging basket assembly 8 is rearward, and at this time operator need to hanging
Move at arm assembly 6, the center of gravity of change hanging basket assembly 8, more slowly adjust the joystick of unidirectional adjustable throttling 3, after leveling
Locked high-pressure ball valve 4, realizes declining hanging basket levelling.
