In prior art, expansion supporting leg has supporting cylinder, supporting cylinder is connected with the sleeve-type suspension gear of the axes normal of axis and supporting cylinder, sleeve-type suspension gear has barrel-type casing, the barrel of barrel-type casing has attaching parts, having in barrel-type casing can at the extended or retracted retracting cylinder of the outer nozzle of barrel-type casing, and supporting cylinder is connected in the retracting cylinder outer end of stretching out the outer nozzle of barrel-type casing.
During installation, the attaching parts of expansion supporting leg suspension gear barrel-type casing is connected in the vehicle frame corner of engineering truck, and the axis of suspension gear barrel-type casing parallels with the vehicle frame face of engineering truck, the axis of supporting cylinder and the vehicle frame face of engineering truck perpendicular.
During use, elongate retracting cylinder, supporting cylinder is stretched out, can expand operation carrying surface, during engineering truck walking, supporting cylinder is retracted, and pushes retracting cylinder, makes the size conforms highway communication of engineering truck to the regulation of self-propelled vehicle size.
Expansion supporting leg, can being connected with the retracting cylinder pull-out of supporting cylinder or advancing barrel-type casing with manpower when expanding or draw in.
When the extended or retracted barrel-type casing of retracting cylinder, in order to avoid the axis of supporting cylinder rotates, barrel-type casing and retracting cylinder can be the square tubes matched.
The suspension gear of the expansion supporting leg of above-mentioned horizontal stand is the suspension gear maintaining supporting cylinder straight-line motion, this suspension gear can only allow retracting cylinder stretch out from the urceolus opening's edge axis direction of barrel-type casing or retract, make supporting cylinder when expanding or draw in, its axis remains on parallel motion on the same plane perpendicular to horizontal stand, namely supporting cylinder can only can not rotate in translation, the expansion supporting leg of horizontal stand is when drawing in, although supporting cylinder draws in, but its axis is vertically being attached to by horizontal stand with horizontal stand, take up room larger, affect the use in some occasion, during expansion supporting leg particularly as engineering truck vehicle frame, affect larger.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and after proposing a kind of gathering in, supporting cylinder takes up room the expansion supporting leg of less horizontal stand.
The utility model realizes with the following method.
The expansion supporting leg of horizontal stand has supporting cylinder, supporting cylinder is connected with the sleeve-type suspension gear of the axes normal of axis and supporting cylinder, sleeve-type suspension gear has circular cylindrical shell, the barrel of circular cylindrical shell has attaching parts, having in circular cylindrical shell can at the extended or retracted flexible cylinder of the outer nozzle of circular cylindrical shell, supporting cylinder is connected in the flexible cylinder outer end of stretching out the outer nozzle of circular cylindrical shell
Screw rod is had in flexible cylinder, guide cylinder is had between circular cylindrical shell and flexible cylinder, the barrel of guide cylinder there is axially directed hole, the inner in axially directed hole is connected with the circumferential pilot hole that angle in circular segment is 90 degree, the barrel location of flexible cylinder is connected with stretches to the inside and outside radial peg of cylinder, the cylinder inner segment of radial peg is meshed with screw flight, the outer section of cylinder of radial peg is embedded in the pilot hole of guide cylinder, screw thread inner end on screw rod, have recessed step between the periphery of screw rod and the bottom land of screw thread, the inner end of screw rod is connected with power intake.
During installation, the power intake in screw rod inner end connects the rotary power unit such as motor, HM Hydraulic Motor, the attaching parts of the utility model suspension gear is connected in the corner of horizontal stand.Rotary power can drive screw rod of the present utility model to rotate.
In use procedure, when the outer section of cylinder of flexible cylinder radial peg be embedded in guide cylinder axially directed hole in time, rotary screw, flexible cylinder is driven to stretch out or retraction from the urceolus opening's edge axis direction of circular cylindrical shell by radial peg, the supporting cylinder being connected in flexible cylinder outer end is made to expand vertically or draw in, supporting cylinder is when expanding or draw in, and its axis keeps parallel motion at grade.After supporting cylinder draws in vertically, on flexible cylinder barrel, the outer section of the cylinder of radial peg is embedded in the circumferential pilot hole of guide cylinder, to a direction rotating screw bolt, recessed ledge frame between at the bottom of the periphery of screw rod and thread groove promotes the cylinder inner segment of radial peg, drive the angle of flexible cylinder along the circumferential direction 90-degree rotation, make the axis 90-degree rotation angle of the supporting cylinder being connected in flexible cylinder outer end, the supporting cylinder being connected in flexible cylinder outer end is circumferentially drawn in; To another direction rotating screw bolt, recessed ledge frame between at the bottom of the periphery of screw rod and thread groove, leave the cylinder inner segment of radial peg, the utility model can be designed to the angle of axis because of gravity 90-degree rotation of supporting cylinder, the outer section of the cylinder of flexible cylinder radial peg is embedded in the axially directed hole of guide cylinder again, then drives supporting cylinder to expand or draw in.
Suspension gear of the present utility model can not only drive supporting cylinder along axis expansion and draw in, can also after drawing in along axis, drive the angle of supporting cylinder 90-degree rotation, supporting cylinder is allowed to be in circumferentially rounding state, make the axis of supporting cylinder parallel with horizontal stand, after supporting cylinder draws in, take up room less, particularly as the expansion supporting leg of engineering truck vehicle frame.
