Description

There is the signal generating device of memory function

Technical field

The present invention relates to a kind of boats and ships logistics conveying equipment, especially a kind of naval vessel logistics equipment is vertical, electric, mechanical, signal generating device that hydraulic pressure three aspects: is interlocked between horizontal feed.

Background technology

The conveying circuit of goods on naval vessel has single horizontal feed, single vertical transport, singlely horizontally rotate conveying, level, the vertical compound conveying of both direction, level, vertically, the compound conveying of three directions of rotation, conveying circuit is more complicated, the structure composition of corresponding conveying equipment is just more complicated, interface in equipment between each functional part is just more, security, the requirement of reliability is just higher, for ensureing the security of goods in course of conveying, simultaneously for ensureing that each building block is in level, vertically, the coordination of three directions such as rotation, trouble free service, between three, require to arrange electric accordingly, hydraulic pressure and mechanical interlocking, the general relatively good realization of electric interlock, hydraulic pressure and mechanical interlocking relative difficult, need in limited space, increase some structures, bring thus maintainability, the problem of the aspects such as reliability.

Summary of the invention

The present invention be to solve that naval vessel logistics equipment is vertical, the interlocking problem of electric, mechanical, hydraulic pressure three aspects: between horizontal feed, and provide a kind of signal generating device with memory function.

For achieving the above object, technical scheme of the present invention is: a kind of signal generating device with memory function, comprise left and right pivoted arm, gear, rotating shaft, collision block, cam, be characterized in: left and right pivoted arm is arranged on the Connection Block of signal generating device by rotating shaft respectively, above left and right pivoted arm, be fixedly connected with respectively gear, and two gears are connected with a joggle, two rotating shaft lower ends are fixedly connected with respectively cam.

When goods bracket moves downward, to transport before cabin in the level that enters, collision block clashes into right-hand rotation arm, and right-hand rotation arm clockwise rotates 90 °.

When goods bracket completes downward picking-up goods and moves upward, before goods bracket leaving water trim chamber, collision block clashes into left-hand rotation arm, and left-hand rotation arm clockwise rotates 90 °.

Below Connection Block, be equipped with and control guiding valve, travel switch or approach switch and the mechanical mechanism of hydraulic stroke, and guiding valve, travel switch or approach switch and the mechanical mechanism of controlling hydraulic stroke contact and are connected with cam.

The invention has the beneficial effects as follows:

The present invention has memory function, can be the needed signal of interlocking between electric control system, hydraulic system, mechanical system transmission three by this device simultaneously.

The present invention can be applied to naval vessel goods particularly some special cargos as the conveying of ammunition, standby redundancy, guarantee article etc., can improve security and the reliability of whole logistics equipment.

Brief description of the drawings

Fig. 1 is structural representation of the present invention;

Fig. 2 is structure cutaway view of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing and embodiment, the invention will be further described.

As Fig. 1, shown in 2, a kind of signal generating device with memory function, comprises left and right pivoted arm 1,2, gear 3, rotating shaft 4, Connection Block 5, cam 6, collision block 7.

Left and right pivoted arm 1,2 is arranged on the Connection Block 5 of signal generating device by rotating shaft 4 respectively, and left and right pivoted arm 1,2 is fixedly connected with respectively gear 3 above, and two gears 3 are connected with a joggle, and two rotating shaft 4 lower ends are fixedly connected with respectively cam 6. Connection Block 5 is equipped with guiding valve, travel switch or approach switch and the mechanical mechanism of controlling hydraulic stroke below, and guiding valve, travel switch or approach switch and the mechanical mechanism of controlling hydraulic stroke contact and are connected with cam 6.

When goods bracket moves downward, before transporting cabin, the level that enters hits right-hand rotation arm 2, right-hand rotation arm 2 clockwise rotates 90 ° and drives left-hand rotation arm 1 to rotate counterclockwise 90 °, drive respectively multiple cams 6 by pair of engaged gears 3, cam 6 can be controlled hydraulic stroke guiding valve, travel switch (or approach switch) and mechanical mechanism, realizes electric, hydraulic pressure and the mechanical interlocking between horizontal transporter by the action separately of stroke slide valve, switch and mechanical mechanism; When goods bracket completes downward picking-up goods and moves upward, when clashing into left-hand rotation arm 1 before bracket leaving water trim chamber, left-hand rotation arm 1 clockwise rotates 90 ° and drives right-hand rotation arm 2 to rotate counterclockwise 90 °, the cam 6 that meshing gear 3 drives simultaneously also rotates simultaneously, the stroke slide valve separately of its control, switch and mechanical mechanism are resetted, and all transmission mechanisms of horizontal transporter can start again normal work.

On naval vessel, need goods to be delivered to superstructure deck from underwater cabin, need to goods be delivered to assigned address by horizontal transporter, again by vertical conveying device by goods vertical transport to superstructure deck, goods is normally carried one by one, as the rhythm control of each station on streamline, as previous beat has been failed, a rear beat can not carry out, often only a set of electrical control need to be set just passable for equipment by land, therefore for machinery, hydraulic system is just fairly simple, but particularly carry special cargo on naval vessel time, its security requirement is higher, simultaneously for improving goods transporting velocity, the transhipment of requirement level is worked with vertical transport simultaneously, therefore between horizontal transporter and vertical conveying device, need to arrange electric, hydraulic pressure, the triple interlock protections of machinery.

The typical case of boats and ships logistics is: horizontal transporter, vertical conveying device are worked alone by transmission mechanism separately, common requirement is in the time that the goods bracket of vertical conveying device enters horizontal transporter operating cabin, the part transmission mechanism of horizontal transporter can not be worked, mutually interfere with the mechanism or the goods that move both vertically with the mechanism that prevents horizontal movement, cause the damage of goods and equipment.

Complete the conveying up and down of goods aboard ship by the shuttling movement of a closed chain, conventionally goods bracket is arranged on chain, this chain can pass through multideck, general cargo hold is positioned at hull underwater multideck, be that goods needs vertical transport to arrive waterline with upper deck, seat corresponding with goods bracket on chain is provided with collision block, in the time that goods bracket moves downward to hold deck, collision block on chain has clashed into signal generating device, now signal generating device has been remembered bracket seat, and information is sent to control system, hydraulic system, mechanical system, when bracket with chain row culture shuttling movement to lower sprocket rear steering for moving upward, when moving up to relevant position, cargo hold top, collision block on chain clashes into signal generating device, now signal generating device is remembered bracket locations again, and information is sent to control system/hydraulic system/mechanical system, complete one action beat.
