The auxiliary ladder is composed of a sliding board, and a luffer, a rotating mechanism, a hydraulic station, a traveling wheel device which are connected to the sliding board, and a lifting mechanism fixed on the wharf, wherein a lifting cylinder causes the traveling wheel device on the sliding board to ascend and descend along an I-steel guide rail on the ladder frame, a rotating platform on the sliding board rotates along a center axis on a horizontal plane, the front end of the rotating platform is hinged with the accommodation ladder which rotates along a bearing on the rotating platform on a vertical plane by stretching and shrinking a luffing cylinder, the heights of the triangular ladder and the accommodation ladder are adjusted, a rotary cylinder causes the accommodation ladder to rotate on the horizontal plane within the range of 120 DEG, and the hydraulic station, the luffer and the rotating mechanism are all in the sliding board and ascend and descend with the sliding board. The present invention has the advantages of compact structure, simplified oil path, reduced oil pipe, safe and reliable use, good working synchronous stability and high sensitivity and is suitable for meeting requirements with big fall and change at oil product wharfs and chemical industry wharfs.

Description

Full hydraulic driven boarding ladder

Technical field

The present invention relates to a kind of specialized equipment boarding ladder, particularly a kind of from boats and ships to the very big walkway of drop the longshore work platform, the full hydraulic driven boarding ladder that uses on various large-scale oil products, chemical industry boat landing suits.

Background technology

General passenger steamer can according to flood tide select ship's deck and harbour drop apart from the less time as the time of sailing, so that Embarking of Passenger.But some mammoth tankers, cargo ship are longer because of the landing pier loading, unloading time, be subjected to fully loaded, the unloaded influence of tidewater fluctuation and goods very big, so the very big upper and lower ship of staff of giving of the drop between deck and harbour brings very big inconvenience, has increased safety hazard and danger again.Boarding ladder is mainly formed by being fixed on the harbour or at main ladder that moves on the harbour and the movable auxilliary ladder to the face of boat deck of energy, at present existing design-calculated boarding ladder can satisfy the operating needs of the harbour face and the deck plane 20m discrepancy in elevation, but the motion of original boarding ladder moving part mainly adopts steel rope to realize, steel rope is easy to wear, twine, fracture, perishable at sea, the rotation of the auxilliary ladder of past boarding ladder relies on the transmission of gear, drop-gear box, and structure is lengthy and jumbled, volume is big.

Patent No. 200310114684.X " rotary passenger boat ladder vehicle ", a kind of ladder vehicle that is made of fixed ladder, side-rolling ladder, the ladder that floats is provided and has increased the fixed ladder part, make the passenger when upper and lower shipping agency is walked, minimizing is rocked, and increases stability, safety, easy to use.Regulate the height of elevator by hydraulic pressure supporting elevation fixed ladder, regulate the pitching of the unsteady terraced angle of flexible realization of the terraced upper cylinder that floats, finally change the stop position and the direction of ladder vehicle as required, but it only suits to use on the little mixed boat harbour of general drop height.

Summary of the invention

Technical matters to be solved by this invention is: a kind of full hydraulic driven boarding ladder is provided, suit especially on oil product, the chemical industry harbour with harbour on the supporting use of fixed equipment ladder, cause oil, the big needs of cargo ship deck drop height change to adapt to because of tidewater fluctuation and oil product, cargo handing, constantly control, regulate the position of boarding ladder, highly, allow boarding ladder be positioned at best operational position all the time, make more safely safety, current easily between oil, cargo ship and longshore work platform of staff.

The present invention addresses the above problem the technical scheme that is adopted: full hydraulic driven boarding ladder by be fixed on have on the harbour main ladder that the ladder that runs ladder constitutes with can be movable to the face of boat deck band triangle ladder, the auxilliary ladder of gangway ladder is formed, described auxilliary ladder is by bonded assembly luffing mechanism on slide and the slide, rotating mechanism, Hydraulic Station, the lift system of walking wheel apparatus and being fixed on the harbour constitutes, the rotation platform front end of described slide one side is hinged with gangway ladder, the opposite side of slide is a flat surface, slide baseplane one end is connected on the slide frame, the upper end of rotation platform is connected with upper support on being fixed on the slide frame, the lower end is connected with Hydraulic Station by lower support, be fixed with away wheel apparatus on the slide frame, walking wheel apparatus moves up and down along the drive of the guide rail on ladder slide, the fixed bearing of the amplitude oil cylinder of described luffing mechanism is fixed on the rotation platform, expansion bearing on the rotation platform is connected on the gangway ladder, the fixed bearing of the rotary oil cylinder of described rotating mechanism is fixed on the slide frame, expansion bearing on the rotary oil cylinder is connected on the lower support, the following end plug of the elevating ram of described lift system is connected with end bearing on the harbour, and the cylinder sleeve of elevating ram upper end is connected with the middle bearing on the slide.

Compared with prior art, the invention has the advantages that: this full hydraulic driven boarding ladder can promote simultaneously, rotate, unsteady omnibearing control of luffing and adjusting, boarding ladder can be changed along with the variation of drop, all activities are controlled by oil cylinder, boarding ladder is positioned on the best operational position all the time, uses safer, reliable.And each oil cylinder except that elevating ram all is directly installed on the slide of boarding ladder, simple in structure, compact, simplified oil circuit, reduced intermediate link and oil pipe, volume is little, by same Hydraulic Station fuel feeding, work synchronism, good stability, highly sensitive, suit especially on oil product, chemical industry harbour, to use, satisfy drop variation demand greatly.When auxilliary ladder rested on the deck plane, oil cylinder was in unsteady mode of operation, and auxilliary ladder utilizes deadweight along with fluctuating in the deck, had avoided utilizing that steel rope may cause gets loose or make auxilliary ladder unsettled, safe in utilization, reliable.
