Abstract
The utility model relates to a gearing lift device for a traction machine, comprising an upper traction frame, a lower traction frame. The utility model is characterized in that a crank arm and a rocking arm which are hinged with the upper and the lower traction frames are arranged between the upper and the lower traction frames. An upper arm of the crank arm is kept parallel with the rocking arm. A lower arm of the crank arm is hinged with an air cylinder. The rocking arm is provided with a mechanical gearing between the hinged points of the rocking arm and the upper and the lower traction frames. The traction speed of the upper and the lower traction frames is enabled to be synchronous. The upper traction frame is moved in parallel corresponding to the lower traction frame. The utility model has the advantages of simple structure, convenient operation, etc.
Description
The utility model relates to the transmission jack up unit of plastic material production field, particularly a kind of traction machine.
Present patent application a few days ago, the transmission jack up unit of the plastic material traction machine of at home and abroad selling, using mostly is greatly by universal connecting shaft knot or by transmissions such as leading screw, finishing bevel gear cuters, exists complex structure, adjust inconvenient up and down, volume is big, and there are shortcomings such as error in the cost height.
Goal of the invention of the present utility model is that haulage speed is synchronous about will providing, and last drawbar frame is relative to the following parallel transmission jack up unit that moves of drawbar frame.
Foregoing invention purpose of the present utility model realizes by following technical proposals:
A kind of transmission jack up unit of traction machine, comprise drawbar frame, following drawbar frame, it is characterized in that being provided with connecting lever and the rocking arm that is hinged with it between the drawbar frame up and down, the upper arm of connecting lever and rocking arm keeping parallelism, underarm and cylinder are hinged, at rocking arm and be provided with mechanical drive between two hinge-points of drawbar frame up and down.
Described connecting lever and rocking arm and up and down hinged and upper arm and rocking arm connecting lever of drawbar frame be parallel to each other, constitute four-bar linkage, the underarm and the cylinder of connecting lever are hinged, like this when cylinder promotes the connecting lever underarm, drive to go up drawbar frame and move control and go up that drawbar frame promotes and the whereabouts compresses section bar thereby connecting lever rotates around hinge-point, simultaneously again because at rocking arm and be provided with mechanical drive between two hinge-points of drawbar frame up and down, during drawbar frame motion so instantly, make to go up the drawbar frame reversing sense with the speed motion by mechanical drive, thereby guarantee to draw synchronous up and down and go up drawbar frame and move relative to drawbar frame is parallel down.
Described mechanical drive by with rocking arm and up and down the coaxial upper and lower sprocket wheel of the hinge-point of drawbar frame, down the drawbar frame drive sprocket, with coaxial two equipment gears of lower sprocket and following drawbar frame drive sprocket and be arranged on upper sprocket wheel and lower sprocket between messenger chain long narrow table partly form, its purpose be to guarantee that by equipment gear and driving chain traction up and down is reverse fast together.
Advantages such as the transmission jack up unit of a kind of traction machine of the utility model structure has and can make that up and down haulage speed is synchronous, and last drawbar frame moves relative to time drawbar frame is parallel, and is simple in structure, easy to use.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment 1: see accompanying drawing 1
A kind of transmission jack up unit of traction machine, relate to the plastic material production field, comprise drawbar frame 1, following drawbar frame 2, last, following drawbar frame 1, be provided with the connecting lever 3 and the Rocker arm 4 that are hinged with it between 2, the upper arm 5 and the Rocker arm 4 keeping parallelism of connecting lever 3, underarm 6 is hinged with cylinder 7, at Rocker arm 4 and two hinge-points 8 of drawbar frame up and down, be provided with between 9 by with Rocker arm 4 and up and down the hinge-point of drawbar frame coaxial last 11, lower sprocket 12, following drawbar frame drive sprocket 13, with coaxial two equipment gears 1415 of lower sprocket 12 and following drawbar frame drive sprocket 13 and be arranged on upper sprocket wheel 11 and lower sprocket 12 between the mechanical drive 10 formed of driving chain more than 16 parts.
