Description
Technical field
The described double acting follow mechanism of the utility model relates to a kind of up-down follower structure of tailstock plate carrying platform.
Background technology
Present existing tailstock plate carrying platform control mechanism has following several kinds of modes when up-down of control tailgate and rotary movement: 1, five cylinders are arranged formula; Up-down by two hoist cylinder control tailgate carrying platforms; The upset of two oil cylinder control tailgate carrying platforms of closing the door, a pressurized cylinder is coordinated the action of the hoist cylinder and the oil cylinder of closing the door; 2, three cylinder arrangements, principle are with first kind, and just hoist cylinder respectively is one with the oil cylinder of closing the door; 3, two cylinder arrangements, promptly a hoist cylinder, the oil cylinder of closing the door utilize arbitrary-movement articulator to coordinate the action of two cylinders.Aforementioned several kinds of tailstock plate carrying platforms have all-in-one-piece, also have foldingly, but hydraulic efficiency pressure system is all complicated, and cost is corresponding also higher.
Summary of the invention
In view of above-mentioned prior art hydraulic efficiency pressure system than complicated problems, the utility model provides a kind of follow mechanism that hydraulic efficiency pressure system is simpler, cost tailstock plate carrying platform control setup low, easy and simple to handle is used that makes.
The technical solution of the utility model is achieved in that
The described double acting follow mechanism of the utility model is made up of main bearing, lift arm, hoist cylinder and carrying platform; One end and the main bearing of lift arm are hinged, the other end and carrying platform left end upper articulation; It is characterized in that being welded with secter pat on the axle sleeve of lift arm and main bearing hinged place, lift arm the knee landing wheel is housed; The main bearing connecting bore at the middle part of the middle part of main bearing and waist shape support is hinged; The bottom that caging bolt is against waist shape support is equipped with in the bottom of main bearing; On the top roller mounting hole of waist shape support roller is housed, the oil cylinder connecting bore of the bottom of hoist cylinder and waist shape support bottom is hinged, and the middle part of piston rod and lift arm is hinged; A lever attachment hole of one end of pole and waist shape support middle and upper part is hinged, the other end and carrying platform left end lower hinge.
The arc surface of the described secter pat of the utility model and lift arm are coaxial with the be hinged axis hole of axle sleeve at place of main support.
The arc surface exposure phase of described roller of the utility model and secter pat supports.
The realization of translation during the lifting/lowering action: when going up lift operations, the oil cylinder piston bar stretches out, and waist shape support is tightly withstood on the caging bolt, thereby waist shape support remains unchanged with respect to main support position; When carrying out step-down operation; Carrying platform forces in lift arm and makes oil cylinder piston bar retraction under the effect of gravity, make carrying platform descend, and also forces in pole simultaneously; Make waist shape support that the possibility that rotates counterclockwise arranged; And at this moment roller leans against on the arc surface of secter pat, waist shape support can not be done rotate counterclockwise, and promptly remains unchanged with respect to main support position.Like this, main bearing, lift arm, pole, carrying platform and four relevant hinge-points have formed a parallel-crank mechanism, make carrying platform in lifting process, remain translation, thereby have guaranteed that carrying platform remains horizontality.
The realization of tilting action: when carrying out step-down operation, when carrying platform fell earthward, landing wheel is kiss the earth at first; At this moment roller and secter pat disengage; Under the effect of carrying platform gravity, the pole left end promotes waist shape support and rotates counterclockwise, and the pole right-hand member is clockwise rotated around the hinge-point of lift arm and carrying platform; Thereby carrying platform is tilted up to the front end kiss the earth, so that goods up and down.
The utility model has adopted the double acting follow mechanism that is made up of waist shape support, secter pat, roller, caging bolt; Guaranteed that main bearing, lift arm, pole, the relevant hinge-point with each of carrying platform remain the parallelogram state in the carrying platform lifting process; Guaranteed that promptly carrying platform remains horizontality, and drop to can wing drop under the effect of gravity behind the ground.
The utility model has the advantages that conspicuously, mainly show:
The carrying platform control setup is if adopt above-mentioned follow mechanism, and then power pack section only needs hoist cylinder to get final product.Like this, hydraulic efficiency pressure system is simpler, and more convenient operation (rotary movement of carrying platform is accomplished by manual work) is suitable for the installation and the use of medium and small lorry.The utility model processing is easy, with low cost, be convenient to advantages such as installation, easy operating, and it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
