Abstract
The utility model discloses an automatic turnover mechanism for a support oil cylinder. The automatic turnover mechanism comprises a vertical oil cylinder, a crank, a connecting rod, a push rod and a fixed guide tube, wherein the crank is fixedly arranged at one side of a cylinder head of the vertical oil cylinder; the crank is hinged with the T-shaped push rod through the connecting rod; the bottom end of a piston rod of the vertical oil cylinder is provided with a movable paw; the piston rod is provided with the U-shaped fixed guide tube through a push plate fixedly arranged on the piston rod; one end of the T-shaped push rod is clamped in a U-shaped slot of the U-shaped fixed guide tube; and the other end of the T-shaped push rod is hinged with the connecting rod through a fixed guide block. The automatic turnover mechanism for the support oil cylinder has the advantages that (1) forces are transferred by the vertical oil cylinder to enable the support oil cylinder to automatically turn over; (2) the piston rod is provided with the fixed guide tube, thus, when falling, the vertical oil cylinder can be prevented from rapidly rotating, and a safety protection action is performed; and (3) the connecting rod, the crank and the push rod of the mechanism are arranged on the outer side face of the vertical oil cylinder, and therefore, the activity space is enlarged.
Description
Technical field
The present invention relates to a kind of crane tool equipment, what be specifically related to is loop wheel machine support oil cylinder automatic turning mechanism.
Background technology
Stretch out supporting leg and generally be used for the lifting operations such as hoisting crane.The existing support oil cylinder that stretches out supporting leg all is that support oil cylinder and movable supporting legs are rigidly connected generally without switching mechanism, and also some hoisting crane upset is with supporting leg cylinder manual overturning 180 degree, then manually lock pin is locked it, manual overturning is wasted time and energy, and has reduced work efficiency; Simultaneously, when supporting leg was turned to control position from top to bottom, owing to there not being shock absorber, support oil cylinder was easy to injure by a crashing object operating personal under action of gravitation.
In addition, support oil cylinder is subjected to the restriction of car chassis height without the hoisting crane of upset performance, thereby affect the wide plasticity of its coupling, simultaneously automobile in the process of moving support oil cylinder easily collide with obstacle, reduce rideability, particularly in the situation that the lorry-mounted crane postposition, the support oil cylinder that can not overturn has reduced departure angle greatly, has reduced the off-road capability of automobile; Loop wheel machine is not in the situation that there is the chassis, and in the occasions such as exhibitions or delivery, supporting leg can not overturn and just bring a lot of troubles.
The utility model content
For the deficiency that above-mentioned prior art exists, the utility model provides the support oil cylinder automatic turning mechanism of a kind of compact conformation, safety of operation.
The technical solution of the utility model is: the support oil cylinder automatic turning mechanism, comprise Vertical Cylinders, crank, connecting rod, push rod, fixed guide pipe, and it is characterized in that: crank is fixed on a side of Vertical Cylinders cylinder head, and crank has T-shaped push rod by rod hinge connection; The piston rod bottom of Vertical Cylinders is furnished with movable sole, by the push pedal that is fixed on the piston rod U-shaped fixed guide pipe is installed on the piston rod; T-shaped push rod one end is stuck in the U-shaped groove of U-shaped fixed guide pipe, and the T-shaped push rod other end is hinged by fixed guide piece and connecting rod.
Advantage of the present utility model: 1. by the Vertical Cylinders power transmission, make the supporting leg automatic turning; 2. the fixed guide pipe is arranged on the piston rod, when Vertical Cylinders falls, can prevent that Vertical Cylinders from sharply rotating, play the safety guard-safeguard effect; 3. the connecting rod of this mechanism, crank, push rod all are installed in the lateral surface of vertical cylinder, have increased activity space.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is right elevation of the present utility model.
The specific embodiment
In Fig. 1, Fig. 2, the support oil cylinder automatic turning mechanism comprises Vertical Cylinders 1, crank 2, connecting rod 3, push rod 4, fixed guide pipe 5, and crank 2 is fixed on a side of Vertical Cylinders 1 cylinder head, and crank 2 is hinged with T-shaped push rod 4 by connecting rod 3; Piston rod 1.1 bottoms of Vertical Cylinders 1 are furnished with movable sole 6, by the push pedal 7 that is fixed on the piston rod 1.1 U-shaped fixed guide pipe 5 are installed on the piston rod 1.1; T-shaped push rod 4 one ends are stuck in the U-shaped groove of U-shaped fixed guide pipe 5, and T-shaped push rod 4 other ends are hinged by fixed guide piece 8 and connecting rod 3.
Supporting leg inside casing 9 and crank 2 maintain static, and push rod 4 can only move at Vertical Cylinders 1 axial direction, and the T word bar of push rod 4 can move freely in the U-shaped groove of fixed guide pipe 5, but can not rotate and break away from the U-shaped groove of fixed guide pipe 5.Open two lock pins 10, when Vertical Cylinders 1 retraction, piston rod 1.1 retractions drive fixed guide pipe 5 retractions.When push rod 4 bottoms and push pedal 8 contact, push rod 4 begins retraction, arrive crank 2 by connecting rod 6 power transmissions this moment, because crank 2 maintains static, push rod 4 can only move along Vertical Cylinders 1 flexible direction, under the effect of antagonistic force, Vertical Cylinders 1 flexing handle 2 centers begin turning, until Vertical Cylinders 1 is retracted fully.Then Vertical Cylinders 1 relative supporting leg inside casing 9 rotations 170 degree manually rotate to it 180 degree, and latch-locking 10 reaches the automatic turning effect.
When Vertical Cylinders 1 is transferred, piston rod 1.1 stretches out, Vertical Cylinders 1 begins rotation, after rotating to a low-angle, Vertical Cylinders 1 begins back rotation and falls under Action of Gravity Field, because 5 effects of fixed guide pipe being arranged, when Vertical Cylinders 1 begins to rotate freely lower backwardness, when the T of push rod 4 prefix arrived U-shaped fixed guide pipe 5 upper limit position, Vertical Cylinders 1 whereabouts of stopping the rotation just can rotate the whereabouts when Vertical Cylinders 1 and the piston rod 1.1 such as only having to continue to stretch out.Until after Vertical Cylinders 1 reached certain-length, Vertical Cylinders 1 was fallen vertical state fully, prevented that like this Vertical Cylinders 1 from sharply descending, and prevents from injuring by a crashing object operating personal under Action of Gravity Field.
