Abstract
The invention relates to a harbor machinery in the mechanical equipment field, in particular to a telescopic locating device of a container spreader. The fixed bracket is fixed with a pin roll 1, a hydrocylinder base and a limit seat, wherein, the pin roll 1 is movably connected with a tension rod, one side of the tension rod is connected with a hydrocylinder by a hydrocylinder pin roll, the other side of the tension rod is provided with a telescopic link which is provided with a locating block, the part on the locating block corresponding to the tension rod end part is provided with a neck, the hydrocylinder is fixed on the fixed bracket by the hydrocylinder base. The invention has the advantages that the telescopic locating device is more flexible, safer and more convenient, thus saving operation time and improving operation working efficiency when hoisting shipping containers with different sizes.
Description
Technical field
The present invention relates to the harbour machinery in the mechanical equipment field, relate in particular to a kind of telescopic positioning device of container spreader.
Background technology
The mechanical type lifting is mainly adopted in the lifting of freight container in the market, but because freight container has plurality of specifications, as 20 chis made in Great Britain, 40 chis etc., in the time will changing another size of lifting behind the freight container that has lifted a kind of specification, the state transformation complexity and the inaccuracy of suspender, bring very big operation easier and intensity to operating personal, and if state transformation location when inaccurate or untimely, also can have bigger potential safety hazard.
Summary of the invention
The objective of the invention is to design a kind of telescopic positioning device that can overcome the container spreader of the deficiencies in the prior art.
Technical scheme for achieving the above object is: the telescopic positioning device of container spreader, comprise fixed mount, be fixed with bearing pin one, cylinder pedestal and limit base on the fixed mount, bearing pin one flexibly connects with pull bar, one side of pull bar connects oil cylinder by the oil cylinder bearing pin, and the opposite side of pull bar is provided with expansion link, and expansion link is provided with locating piece, corresponding tie rod end is provided with draw-in groove on the locating piece, and oil cylinder is fixed on the fixed mount by cylinder pedestal.In the technical program, expansion link moves in suspender have been controlled the suspender state promptly to control suspender has been the freight container that is used to lift which kind of size under current state.
Described cylinder pedestal connects oil cylinder by bearing pin two.
The invention has the beneficial effects as follows: more flexible, safer, more convenient when the freight container of lifting different size, save the operating time, improve the operation work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure, 1 is locating piece, and 2 is pull bar, and 3 is oil cylinder, and 4 is cylinder pedestal, and 5 is expansion link, and 6 is that bearing pin one, 7 is the oil cylinder bearing pin, and 8 is that bearing pin two, 9 is a fixed mount, and 10 is limit base, and 11 is draw-in groove.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
The telescopic positioning device of container spreader, be fixed with bearing pin 1, cylinder pedestal 4 and limit base 10 on the fixed mount 9, bearing pin 1 flexibly connects with pull bar 2, one side of pull bar 2 connects oil cylinder 3 by oil cylinder bearing pin 7, the opposite side of pull bar 2 is provided with expansion link 5, expansion link 5 is provided with locating piece 1, and corresponding pull bar 2 ends are provided with draw-in groove 11 on the locating piece 1, and oil cylinder 3 connects cylinder pedestal 4 by bearing pin 28 and is fixed on the fixed mount 9.
For ease of understanding brief description principle of work of the present invention:
When expansion link 5 is in 20 feet or 40 feet or 45 feet needs location, piston rod withdrawal by solenoid control oil cylinder 3, pull bar 2 rotates counterclockwise around bearing pin 6, up to 11 li of the draw-in grooves that falls to expansion link 5 corresponding locating pieces 1, expansion link 5 is locked can not to carry out expanding-contracting action, thus the positioning action of playing.When expansion link 5 need unlock when carrying out expanding-contracting action, the piston rod of solenoid control oil cylinder 3 stretches out, pull bar 2 clockwise rotates (because of the restriction of limit base 10 around bearing pin 6, can only forward the upright position to), pull bar 2 breaks away from the draw-in groove of expansion link locating piece 1, and expansion link 5 is disengaged locking can carry out expanding-contracting action.
So, the state of suspender conversion lifting different size freight container has promptly been controlled in moving, locking of expansion link 5.
