Description
Technical field
The utility model belongs to hoisting crane, especially relates to a kind of hydraulic ram of hoisting crane.
Background technology
Common hoisting crane and truck with loading crane do not have the function of rotation with the vertical hydraulic supporting leg of hoisting crane, at first when hoisting crane the time at upward slope, descending or at rugged road traveling, because the crossing ability of hydraulic ram is relatively poor, hydraulic ram easily and ground interfere, even have an accident, traffic accident; Secondly because remaining with ground, the vertical leg of common hoisting crane becomes plumbness, when loop wheel machine portion need install with two propons chassis such as 6 * 2,8 * 4, will cause vertical hydraulic supporting leg and tire to interfere, therefore must change crane structure, sometimes even not only this crane structure to be changed but also chassis structure will be changed, waste time and energy, often can not reach desirable effect; Three, when the hoisting crane vertical leg breaks down, must take whole supporting leg apart and keep in repair, labor content and maintenance cost when having increased maintenance greatly.
Summary of the invention
The purpose of this utility model provides the quick detachable rotating hydraulic of a kind of hoisting crane supporting leg, not only improve the through performance of hoisting crane car load, can guarantee again under the limited situation in installation site that vertical hydraulic ram can be adjusted dodges the labor content in the time of can also reducing maintenance simultaneously.
The purpose of this utility model is achieved like this: the quick detachable rotating hydraulic of a kind of hoisting crane supporting leg, comprise horizontal hydraulic pressure supporting leg and vertical hydraulic supporting leg, the vertical hydraulic supporting leg is installed on the overhanging end of horizontal hydraulic pressure supporting leg, it is characterized in that: at the bottom of the overhanging end section of horizontal hydraulic pressure supporting leg fixed installation upper junction plate, this upper junction plate can be the right angle trough plate that rectangular plate or notch make progress, the middle part of the lower end of this upper junction plate left and right side be welded symmetrically respectively be before and after to the main short steel pipes section that is provided with, like this about main short steel pipes section, upper junction plate and horizontal hydraulic pressure supporting leg form an integral body; Lower connecting plate at the top of vertical hydraulic supporting leg fixed installation rectangle, secondary lengths of steel pipes before and after the upper end of the left and right side of this lower connecting plate all is welded symmetrically at interval, opening apart from should be between the secondary lengths of steel pipes in these front and back greater than the length of main short steel pipes section, and when upper junction plate and lower connecting plate are fitted up and down, secondary lengths of steel pipes should and be positioned on the same horizontal center line with each main short steel pipes section corresponding setting-in of energy before and after each of left side and right side, the corresponding respectively bearing pin that installs in secondary lengths of steel pipes and the main short steel pipes section links into an integrated entity horizontal hydraulic pressure supporting leg and vertical hydraulic supporting leg before and after each of left side and right side; On the front and back end section of the bearing pin on left side or right side, install arc plate respectively, the uniform from top to bottom spacing hole that is in same rotation arc radius that offers on this arc plate, the internal diameter of the secondary lengths of steel pipes in the diameter of this each spacing hole and main short steel pipes section and front and back equates, and the radius of rotation of the main short steel pipes section of the rotation arc radius of each spacing hole and homonymy and front and back pair lengths of steel pipes is identical and corresponding to same centre of gration.
When hoisting crane is in running order, the vertical hydraulic supporting leg need support on the ground, as long as be installed on before and after each of the upper and lower connecting panel left and right sides in the secondary lengths of steel pipes and main short steel pipes section with the fixed vertical hydraulic ram mode of operation of assurance hoisting crane with two bearing pins are corresponding respectively; When the vertical hydraulic supporting leg of hoisting crane need rotate, earlier the bearing pin in left side is pulled out, install bearing pin in the main short steel pipes section on upper junction plate and also load onto arc plate in front and back, after the vertical hydraulic supporting leg being rotated to the position of needs, install bearing pin and fixing in the secondary lengths of steel pipes in the cooresponding hole on the arc plate of front and back and the front and back on the lower connecting plate again, guarantee that the vertical hydraulic supporting leg can not interfere with tire etc., dodges effect thereby play; If horizontal hydraulic pressure supporting leg, vertical hydraulic supporting leg break down, can pull out bearing pin rapidly and dismantle, judge at failure analysis, respectively horizontal hydraulic pressure supporting leg, vertical hydraulic supporting leg are keeped in repair, both handled easily was time saving and energy saving again, and simple in structure, cost is low.
The quick detachable rotating hydraulic of the hoisting crane that the utility model proposed supporting leg, can guarantee the through performance of car load, can guarantee again under the limited situation in installation site that vertical hydraulic ram assembly can be adjusted dodges, but and improve the commonality of similar hoisting crane, and made things convenient for operation, reduced cost.
Now in conjunction with the accompanying drawings and embodiments the quick detachable rotating hydraulic of the hoisting crane that the utility model proposed supporting leg is described further.
