Abstract
The utility model relates to a kind of lorry-mounted crane telescopic boom and stretches loop soon, and comprise the telescopic oil cylinder that several are connected, telescopic oil cylinder is connected with a loop, and this loop is provided with several and performs the block of valve, its power supply is connected with change-over valve.Hydraulic circuit is done change design, therefore have and do not affect integral layout, do not affect whole traffic safety, increase work efficiency, the advantages such as controlling is strong, be applicable to each money lorry-mounted crane telescoping mechanism uses.
Description
Technical field
The utility model belongs to lorry-mounted crane technical field, relates to a kind of lorry-mounted crane telescopic boom and stretches loop soon.
Background technology
Existing lorry-mounted crane conventional telescopic arm stretching speed is general comparatively slow, out of reach operating needs in some cases.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art
,the utility model provides a kind of lorry-mounted crane telescopic boom to stretch loop soon, it passes through hydraulic efficiency pressure system, oil inlet quantity when regulating oil cylinder to stretch out, make it reach the object load-transfer device tail lamp bracket accelerating speed of stretching out under than equal traffic conditions when ensureing oil cylinder smooth motion, taillight filament is not easy to damage, and during unloading, goods can not lamp bracket compressive strain.
The utility model solves the technical scheme that its technical matters adopts: a kind of lorry-mounted crane telescopic boom stretches loop soon, comprise the telescopic oil cylinder that several are connected, telescopic oil cylinder is connected with a loop, and this loop is provided with several and performs the block of valve, its power supply is connected with change-over valve.
The beneficial effects of the utility model are: do to change design on hydraulic circuit, therefore have and do not affect integral layout, do not affect whole traffic safety, increase work efficiency, the advantages such as controlling is strong, are applicable to each money lorry-mounted crane telescoping mechanism uses.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-telescopic oil cylinder, 2-performs the block of valve, 3-change-over valve.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See Fig. 1, a kind of lorry-mounted crane telescopic boom stretches loop soon, and comprise the telescopic oil cylinder 1 that several are connected, telescopic oil cylinder 1 is connected with a loop, and this loop is provided with several and performs the block of valve 2, its power supply is connected with change-over valve 3.
The utility model is done to change design on hydraulic circuit, therefore has and does not affect integral layout, do not affect whole traffic safety, increase work efficiency, the advantages such as controlling is strong, is applicable to each money lorry-mounted crane telescoping mechanism uses.
