Abstract
The utility model discloses a translation hoisting device of a turnover accommodation ladder, which comprises a traction system, a stationary rail and a dynamic rail. The traction system comprises a winch, a steel rope, pulleys and a rotary wheel; the winch is mounted on a deck and the steel rope wound on the winch is connected with the turnover accommodation ladder through the rotary wheel. The stationary rail is mounted on the lower side eave of the upper layer deck, the length direction of the stationary rail is vertical to the ship side, the dynamic rail and the stationary rail are in thesame direction, positioning holes for mounting bolts are additionally and respectively arranged on the lateral surfaces of the left and right ends of the stationary rail. Two pulley blocks are arranged on the top part of the left end of the dynamic rail, two pulleys are arranged on the right end, and the dynamic rail utilizes the pulleys to realize translation slip along the stationary rail. Whenthe dynamic rail is positioned, the turnover accommodation ladder can be lifted or stored. The overhead translation hoisting device has high hoisting altitude and realizes the barrier free accessibility for staff under any working condition.
Description
Technical field
The utility model relates to a kind of ship deck machinery, and more particularly, the utility model relates to a kind of translation lifting appliance of convertible gangway ladder.
Background technology
Convertible gangway ladder is a kind of lifting and gangway ladder of turning device provided for oneself, takes up an area of when this ladder compact conformation, easy to operate, safe in utilization, collection and economizes, and it is supporting to be particularly suitable for middle craft.Convertible gangway ladder is installed on the ship side deck usually, and when boats and ships berthed harbour, lifting was provided in utilization for oneself and turning device is done the lifting of gangway ladder, thereby sets up the walkway between ship and harbour.Prior art has solved boats and ships preferably when berthing harbour, and gangway ladder sets up problem, and gangway ladder collection problem during the boats and ships departure.But, still there is unsatisfactory part in prior art products in application, promptly providing lifting appliance for oneself directly is fixed on the ship side deck, its sling height is limited and do not have a translation structure, when the ship at full load, diff-H between ship side deck and the quay surface is less than adult normal height, and free height is little between gangway ladder that puts down and the suspension bracket, personnel is passed through have some setbacks.Under this situation, abandon convertible gangway ladder usually, directly set up simple and easy springboard and make personnel's temporary access road at harbour and gun wale.Although this way is feasible, effective, poor safety performance.In addition, the thing of setting up simple and easy springboard needs ship and harbour side to coordinate successfully just may implement.This work difficulty is big in the reality, and it is big more to take the long more cost of springboard time.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, a kind of translation lifting appliance of convertible gangway ladder is proposed, this device is fixedly connected on the following eaves in promenade deck, its lifting position high starting point, the sling height height, have bigger translation space, guarantee under any working condition, can both accomplish personnel's barrier free accessibility.
The utility model is achieved through the following technical solutions technical goal.
The translation lifting appliance of convertible gangway ladder, it comprises the moving rail that traction system control and quiet rail roll and cooperate.Described traction system comprises winch, cable wire, pulley and runner, and convertible gangway ladder is involved by cable wire.Its improvements are: described quiet rail is fixedly connected on the following eaves of promenade deck, the length direction and the gun wale of quiet rail are perpendicular, moving rail and quiet rail are in the same way, two groups of pulleys that moving both sides, rail left end top are provided with separately roll along quiet rail, moving rail right-hand member both sides are provided with two groups of runners separately, the cable wire of winch traction affects convertible gangway ladder through runner, and described quiet rail left and right sides end side surface is respectively equipped with knock hole and the locating dowel pin formation position limiting structure that matches.
In the said structure, when the quiet relatively rail of moving rail slides into end position to the right, latch is filled in the right knock hole start rail of quiet trackside face and located, under this location condition, make the descending operation of convertible gangway ladder.Pull out latch, coincide until quiet rail by contracting in the moving rail of cable traction, latch is changed to be inserted in the knock hole of a quiet trackside face left side again and fix moving rail by winch.
The utility model compared with prior art has following good effect:
1, the bearing fit kinematic pair of forming by moving rail and quiet rail, translation amplitude is big, satisfies the position adjustment of convertible gangway ladder;
2, the lifting translating device sling height height put of height is guaranteed can both accomplish personnel's barrier free accessibility under any working condition;
3, integral structure is simple, easily makes.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that scheme drawing is looked on the right side of Fig. 1.
Fig. 3 is the utility model cable wire tendency scheme drawing.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The translation lifting appliance of convertible gangway ladder shown in the drawings, it comprises the moving rail 1 that traction system control and quiet rail 2 roll and cooperate.Described traction system comprises winch 6, cable wire 7, pulley 3 and runner 5, and winch 6 is installed above deck, and the cable wire 7 that winch 6 twines involves convertible gangway ladder 8 through runner 5.Described quiet rail 2 is fixedly connected on the following eaves of promenade deck 9, and the length direction and the gun wale of quiet rail 2 are perpendicular, moves rail 1 and quiet rail 2 in the same way, and quiet rail 2 left and right sides end side surface are respectively equipped with the knock hole that latch 4 is installed.Moving rail 1 left end top is provided with two groups of pulleys 3 separately, and right-hand member is provided with corresponding two groups of runners 5, and moving rail 1 utilizes pulley 3 along quiet rail 2 sliding translations.When moving rail 1 moves to end position to the right, latch 4 is inserted into start rail 1 location in the quiet rail 2 right-hand member knock holees, start winch 6 pull lines 7, make convertible gangway ladder 8 descending operations by the rotation of runner 5.Pull out latch 4, coincide until quiet rail 2 by contracting in the moving rail 1 of cable wire 7 traction, latch 4 is changed be inserted into start rail 1 location in the quiet rail 2 side left end knock holees again by winch 6.The high horizontalization of the utility model moves lifting appliance, and the sling height height can both be accomplished personnel's barrier free accessibility under any working condition.
