Abstract
A kind of folding M type stretches front leg strut, comprises one-level supporting leg frame, one-level folds driving cylinder, secondary supporting leg frame, secondary fold driving cylinder, three grades of supporting leg frames, the flat driving cylinder of tertiary effluent, vertical telescopic inside casing, vertical drive cylinders.The utility model greatly reduces the space shared by vertical leg, avoid vertical leg and tire is interfered, more extensive to large-tonnage Chassis selection, after all oil cylinders are full reduced, in horizontal surface, become M type, decrease horizontal direction size, also increase span simultaneously, supporting leg job stabilization has had large increase, because one-level supporting leg frame can rotate to an angle around frame, considerably increases operating angle scope.
Description
Technical field
The utility model relates to lorry-mounted crane technical field, is specifically related to a kind of folding M type and stretches front leg strut.
Background technology
The version of existing front leg strut has: a word front leg strut of little tonnage, a front leg strut that staggers for medium-sized tonnage, in order to increase the two-stage telescopic outrigger that stability adopts in medium-and-large-sized tonnage.Wherein to there is span little for a word front leg strut, to the defect such as inapplicable of medium-and-large-sized tonnage, and a front leg strut that staggers, although supporting leg span is larger, but because two supporting leg of stretching all is applied on large-tonnage truck-mounted crane substantially, the chassis of the loop wheel machine configuration of this tonnage very most of is all front four rear eight chassis, because the front axle of the production of manufacturer is apart from less, and a front leg strut that staggers for medium-and-large-sized tonnage to take chassis ridgepole space large, the tire of vertical leg meeting and the second axle is interfered to a great extent, the space that this and customer requirement loop wheel machine take is the smaller the better, at utmost container space is strengthened to reach, increase transportation volume, thus the object increasing profit deviates from completely mutually.Meanwhile, owing to staggering, a supporting leg can only stretch out at vertical surface, can not transfer adapt to various operating mode, so the scope of work of loop wheel machine is limited in horizontal surface inward turning.And existing secondary telescopic outrigger, the general twin-tub that adopts drives, and occupies the space of a lot of supporting leg, outside the supporting leg that the oil pipe of Vertical Cylinders can only be installed, has a strong impact on loop wheel machine so attractive in appearance, and oil pipe is easily swiped thing in the process of moving, very dangerous.
And it is existing a kind of with solving also having of the above-mentioned problem staggered existing for front leg strut lock, that is exactly swing leg, the supporting leg of this version, its lock pin requires strict, and the power that supporting leg is subject to is very large, on market, most of swing leg is when lifting operation, has very large potential safety hazard, time have swing leg lock pin crack conditions to occur.Simultaneously because large-tonnage vertical leg is too heavy, artificial being difficult to rotates, then adopts hydraulic oil cylinder driving, but this considerably increases cost again.
Utility model content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of folding M type and stretches front leg strut, by folding at front leg strut, reduce the lateral dimension of vertical leg, avoid vertical leg and tire is interfered, be suitable for more multi-state, add operating angle scope.
The technical solution of the utility model is: a kind of folding M type stretches front leg strut, comprise one-level supporting leg frame, one-level fold driving cylinder, secondary supporting leg frame, secondary fold driving cylinder, three grades of supporting leg frames, the flat driving cylinder of tertiary effluent, vertical telescopic inside casing, vertical drive cylinders, it is characterized in that, described one-level supporting leg frame hinge joint is in frame, one-level folds the hinge joint of driving cylinder one end in frame, and one-level folds the driving cylinder other end and one-level supporting leg frame links; Described secondary supporting leg frame and one-level supporting leg frame link, and secondary folds the hinge joint of driving cylinder one end on one-level supporting leg frame, and secondary folds the hinge joint of the driving cylinder other end on secondary supporting leg frame; It is interior and flexible in secondary supporting leg frame that described three grades of supporting leg frame one end are sleeved on secondary supporting leg frame, and the flat driving cylinder one end of tertiary effluent is fixed on three grades of supporting leg frames, and the other end of the flat driving cylinder of tertiary effluent is fixed on secondary supporting leg frame; Vertical telescopic inside casing is sleeved in three grades of supporting leg frames, and the cylinder barrel end of vertical drive cylinder and three grades of supporting leg frames link, and rod end and the vertical telescopic inside casing of vertical drive cylinder link.
Advantage of the present utility model: the utility model greatly reduces the space shared by vertical leg, avoid vertical leg and tire is interfered, more extensive to large-tonnage Chassis selection, after all oil cylinders are full reduced, in horizontal surface, become M type, decrease horizontal direction size, also increase span simultaneously, supporting leg job stabilization has had large increase, because one-level supporting leg frame can rotate to an angle around frame, considerably increases operating angle scope.

Detailed description of the invention
Now in conjunction with the following drawings, utility model is described in detail.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, one-level supporting leg frame 2 links in frame 1, one-level folds the hinge joint of driving cylinder 3 one end in frame 1, one-level folds driving cylinder 3 other end and one-level supporting leg frame 2 links, and folds cylinder 3 drive one-level supporting leg frame 2 folding in horizontal surface relative to frame 1 by one-level; Secondary supporting leg frame 4 and one-level supporting leg frame 2 link, secondary folds the hinge joint of driving cylinder 5 one end on one-level supporting leg frame 2, secondary folds the hinge joint of driving cylinder 5 other end on secondary supporting leg frame 4, folds driving cylinder 5 make secondary supporting leg frame 4 folding in horizontal surface relative to one-level supporting leg frame 2 by secondary; Three grades of supporting leg frame 6 one end are sleeved in secondary supporting leg frame 4, and by flexible in secondary supporting leg frame 4 under the effect of the flat driving cylinder 7 of tertiary effluent, the hinge joint of tertiary effluent flat driving cylinder 7 one end is on three grades of supporting leg frames 6, and the other end hinge joint of the flat driving cylinder 7 of tertiary effluent is on secondary supporting leg frame 4; Vertical telescopic inside casing 8 is sleeved in three grades of supporting leg frames 6, the cylinder barrel end of vertical drive cylinder 9 and three grades of supporting leg frames 6 link, rod end and the vertical telescopic inside casing 8 of vertical drive cylinder 9 link, and under the effect of vertical drive cylinder 9, vertical telescopic inside casing 8 stretches relative to three grades of supporting leg frames 6.
