Description
Technical field
The utility model belongs to the technical field of compartment protective cover plate assembly parts, particularly a kind of compartment protective cover plate hand turnover mechanism.
Background technology
When loading body loads and transports Powdered goods (like bulk cement, lime, stone flour etc.) or goods big dust (like building waste etc.) is arranged, or avoid wet by the rain and burnt by the sun etc., often will car body top be covered with cover plate or tarpaulin.The compartment is meant various goods carrying vehicles compartment, also comprises railway carriage etc.Because general compartment is very high and fill goods; Particularly powdered goods, earth, sandstone etc. are easy to be higher than the compartment end face, form the material of mountain shape, need the people to climb to covered protection cover plate or tarpaulin above the compartment; Working strength is big, the covering difficulty is big, has more very big danger.Also have and adopt motor drive mechanism to carry out the covering operation of cover plate or tarpaulin, still, it is malfunctioning to facts have proved that motor drive mechanism not only damages easily, and cost is very high, is not easy after the damage to repair, and makes the application of the protective cover plate of motor drive mechanism that limitation arranged.
The utility model content
The technical matters that the utility model will solve is; For overcoming the shortcoming of background technology; Design a kind of manually operated compartment protective cover plate switching mechanism, do not need the people to climb car body top, manual control is with the protective cover plate covering compartment that is flipped open on ground; Thereby reach neither fragile, cost is low, easy to operate, reduce labour intensity again, guarantee the purpose of personal safety.
The technical scheme of the utility model is following.
A kind of compartment protective cover plate hand turnover mechanism is characterized in that, structure comprises first worm decelerating machine 1, first output shaft 8, second worm decelerating machine 5, second output shaft 15, transmission shaft 4, two protective cover plates 7, crank 10; Crank 10 is installed on the compartment 12 through supporting seat 11, and crank 10 connects and driving transmission shaft 4 through chain drive structure or Bevel Gear Drive structure; First worm decelerating machine 1 and second worm decelerating machine, 5 switched in opposite are installed on the compartment 12 through connecting seat 13 respectively, are connected also by transmission shaft 4 to drive first worm decelerating machine 1 and second worm decelerating machine 5; The major axis of the protective cover plate 7 of compartment one side is captiveed joint with first output shaft 8 of first worm decelerating machine 1, and the major axis of the protective cover plate 7 of compartment opposite side is captiveed joint with second output shaft 15 of second worm decelerating machine 5; Two protective cover plates 7 are installed in 12 upper ends, compartment through support orifice plate 6 respectively and are overturn around the axis that supports orifice plate 6 by first output shaft 8 and second output shaft, 15 propelling energys.
Described chain drive structure is that crank sprocket wheel 9 is connected with crank 10, being fixed on the transmission shaft 4 of driving chain wheel 2 coaxial lines; There is chain 3 to be connected between crank sprocket wheel 9 and the driving chain wheel 2.
The working process of the utility model is; The artificial crank 10 that rotates then rotates connected crank sprocket wheel 9, and crank sprocket wheel 9 rotates driving chain wheel 2 through chain 3; Driving chain wheel 2 drives transmission shaft 4, and transmission shaft 4 drives first worm decelerating machine 1 and second worm decelerating machine 5.The protective cover plate 7 that 15 of second output shafts of first worm decelerating machine, 1 first output shaft 8 and second worm decelerating machine 5 drive both sides respectively covers above the axis while of supporting orifice plate 6, reverse each other upwards upset was with the compartment.Backward rotation crank 10, two protective cover plates 7 are reverse flip simultaneously, gets back to the initial position---the outside face of the 12 liang of side carriage plates in compartment.When adopting the Bevel Gear Drive structure, the artificial crank 10 that rotates, the transmission through conical gear drives transmission shaft 4 and rotates, and remaining working process is with above-mentioned identical.
First worm decelerating machine 1 and second worm decelerating machine 5 are preferably selected the worm decelerating machine with auto-lock function for use.Second output shaft, 15 switched in opposite of first output shaft 8 of described first worm decelerating machine 1 and second worm decelerating machine 5; Promptly two hands of worms are opposite; Left-handed another dextrorotation of one of which, if be both with the rotation direction worm decelerating machine, then can be through gear cluster with one of them worm decelerating machine switching-over.
First worm decelerating machine 1 and second worm decelerating machine 5 can be driven by transmission shaft 4 and rotate two protective cover plates 7 simultaneously synchronously.Also can divide and successively rotate protective cover plate 7 respectively, this moment, transmission shaft 4 was segmentations, and each section connects respectively and drive first worm decelerating machine 1 and second worm decelerating machine 5, and crank 10 is through two sections of arrangement of clutch difference rotating drive shaft 4.The purpose of doing like this is exactly more laborsaving when operation.
The chain sprocket drive structure of the utility model can be divided multistage transmission, is convenient to layout and laborsaving.Crank 10 can stretch, and retracts to 12 outside faces inboard, compartment when not using, in case scratching is dangerous.
The compartment protective cover plate hand turnover mechanism of the utility model significantly reduces artificial working strength and danger when covering the compartment with tarpaulin, has simple in structure, characteristics such as cost is low, easy-maintaining again, is with a wide range of applications.
