Bearing 2 and joint plate I 5 are provided with the chain wheel set of linkage work, described chain wheel set is by chain 7 transmission, and the side below bearing 2 is provided with actuating unit 8, described chain 7 one end is connected with actuating unit 8, the other end, by being hinged on joint plate II 6 after chain wheel set, controlling postbrachium 3 after pulling joint plate II 6 carry out linkage work with forearm 4 to make actuating unit 8 by chain 7.
Be more than a kind of basic embodiment of the present utility model, further improvement, optimization or restriction can be made on the basis of above technical scheme.
Further, described actuating unit 8 is hydraulic ram, and be provided with chain connecting block 801 in its piston rod end, chain 7 is connected to facilitate, middle-size and small-size hydraulic ram selected by actuating unit 8, takies volume little and convenient to install, is applicable to very much the weight lifting under the multiple occasion of reply and space condition in this, as power, in addition, actuating unit 8 also can the power system that coordinates with worm-gear speed reducer of application of electric motors.
Further, described chain wheel set comprises the sprocket wheel III 11 be arranged on chain wheel I 9 on bearing 2 and chain wheel II 10 and joint plate I 5, and the mandrel of sprocket wheel III 11 and connecting rod I 301 are coaxially arranged saving the jointed shaft on plate I 5, chain 7 is connected saving the hinged axle head on plate II 6 with connecting rod IV 402 respectively by after chain wheel I 9, chain wheel II 10 and sprocket wheel III 11, actuating unit 8 pulls or loosens chain 7, make postbrachium and forearm linkage work by the cooperation of three sprocket wheels, complete weight lifting or fall;
Further, for tackling the weight lifting under multiple occasion, described bearing 2 bottom is installed on single-revolution column 1, the weight lifting on 360 ° of directions can be realized, to tackle the weight lifting problem of all directions angle, it can be hook that described extension refitting puts 601, manipulator, electromagnetic absorption device or vacuum absorption device, for actual conditions reasonable selection, simultaneously, described lifting machine structure is simple, volume is little, fixed type can be set to, portable structure or be arranged on the several work platforms such as in-vehicle, range of use is wide, field operation can be carried out under various place and space condition.
Further, select the prerequisite of hydraulic ram at actuating unit 8 under, for the sake of security, travel switch 12 is provided with in actuating unit 8 side, to limit the end position of chain connecting block 801 up-and-down movement, when chain 7 moves to end position, travel switch 12 can be triggered, to close actuating unit 8, guarantee the safety of equipment and the person in use procedure.
When using lifting machine hoisting heavy described in the utility model, first start by the line connection switch be arranged on joint plate II 6 actuating unit 8 be made up of hydraulic ram, the piston rod of hydraulic ram moves down, thus pull chain 7 downwards, postbrachium 3 and forearm 4 is made to produce interlock effect, connecting rod I 301 and connecting rod II 302 by respectively with the jointed shaft core on its each comfortable bearing 2 for the center of circle rotates counterclockwise, envoy's plate I 5 produces the displacement component x of close bearing 2 side in a horizontal direction
1; Now, the connecting rod III 401 in forearm 4 and connecting rod IV 402 rotate doing correspondence with the jointed shaft core on its each leisure joint plate I 5 for the center of circle respectively, and envoy's plate II 6 produces the displacement component x away from bearing 2 side in a horizontal direction equally
2; Due to connecting rod I 301, connecting rod II 302, connecting rod III 401 and connecting rod IV 402 identical length etc. and correspondence is parallel between two, so the horizontal displacement components x of joint plate I 5
1with the horizontal displacement components x of joint plate II 6
2equal and opposite in direction, direction are contrary, thus finally can the level attitude of envoy's plate II 6 constant, only produce the displacement on vertical direction, complete the vertical uplift of weight, in like manner, weight can vertically decline;
When needs lifted weight parallel motion, only need the power that operator applies in a horizontal direction to joint plate II 6 or lifted weight, weight parallel motion can be completed, and under the effect of parallel four-bar linkage, weight translation motion is in sustained height all the time, so level force is not completely by weight gravity effect, the friction force that only need overcome each hinge-point in four-bar linkage can complete weight parallel motion, coordinate rotary column 1 again, weight just can be moved into arbitrary desired location within the scope of certain space, very practical and increase work efficiency.
