Description
Technical field
The utility model relates to drag link mechanism, relates in particular to a kind of Telescopic handle mechanism of the sea hatch cover opening/closing mechanism for space station, deep-sea or bathyscaph, submarine.
Background technology
Maritime cabin is remote underwater manipulation robot (Remotely Operated Vehicle, ROV) or single normobaric diving harness (Atmospheric Diving Suit, ADS), a trouble free service passage of turnover space station, deep-sea or bathyscaph, submarine, and sea hatch cover opening/closing mechanism is that robot (ROV) and single normobaric diving harness (ADS) are laid and the critical component reclaimed.It is to adopt two opposite opened hatch covers, and opens hatch cover with the mode of operation of outside translation respectively.
At present, state, inside and outsidely generally adopt convertible and sliding sea hatch cover opening/closing mechanism.Convertible hatch cover mechanism for opening/closing is to adopt two opposite opened hatch covers, and opens or closes hatch cover with mode of operation outside, inwardly upset respectively; And sliding hatch cover mechanism for opening/closing, to utilize the mode of operation that dragging track carries out slipping motion to be set on the outside face of space station, deep-sea to open or close hatch cover, when for robot (ROV), being laid under water and reclaiming, provide a servicesubway.
In existing translational sea hatch cover opening/closing mechanism, in order to keep hatch cover, opening, in closing course all the time in the translation state, adopted the space parallel four-bar mechanism, that is: by the right angle rocking arm, the geometric configuration of the space parallel four-bar mechanism that a pull bar and upper and lower four hinges installation fulcrum form, any position of its spatial four-bar mechanism is all parallelogram in the projection of Transverse plane, like this, just from geometrical property and the hinge of mechanism itself, install position of the fulcrum, guaranteed the path of motion of hatch cover, wherein, the articulationes cylindroideus lining is equipped with at the pull bar two ends, and its length is fixed.The shortcoming of its existence is as follows:
(1) due to right angle rocking arm and pull bar and by upper and lower four hinges, the four-bar mechanism that fulcrum forms to be installed be the space parallel four-bar mechanism, it requires four hinge axes of four-bar mechanism, spatially to meet very high parallelism requirement, otherwise, in hatch cover unlatching, closing course, there will be pull bar " stuck " phenomenon, last, cause hatch cover to rest on a certain position, can't open, closure;
(2) because pull bar (comprising: the upper and lower hinge of right angle rocking arm and pull bar is installed fulcrum) two ends are all to adopt the articulationes cylindroideus lining, and the articulationes cylindroideus lining only has a degree of freedom rotated along its axis direction, it can not be regulated the rotational freedom of other direction automatically, like this, just increased the difficulty in the processing of hatch cover mechanism for opening/closing and Installation and Debugging, simultaneously, also be unfavorable for care and maintenance in the future;
(3) length due to drag link mechanism is changeless, and therefore, it can not carry out length adjustment, can only be by adjusting the position that under pull bar, hinge is installed fulcrum, carry out the motor coordination relation of adjusting cabin lid mechanism for opening/closing, mounting process is unreasonable, the Operation and Maintenance inconvenience.
The utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide the Telescopic handle mechanism of an a kind of end with angle Zhi Guanjie, it can be in the hatch cover opening-closing process of maritime cabin, maritime cabin hatch cover is carried out to motor coordination, make maritime cabin hatch cover path of motion all the time in the motion of translation state; The pull bar that may occur " stuck " phenomenon, the reliability and the safety that have improved sea hatch cover opening/closing mechanism have been avoided at maritime cabin hatch cover in unlatching, closing motion process; Simultaneously, reduced processing and the setting accuracy of sea hatch cover opening/closing mechanism, be convenient to maintenance and safeguard.
The purpose of this utility model is realized by following technical scheme:
A kind of Telescopic handle mechanism, it is characterized in that: comprising: oscillating bearing, articulationes cylindroideus lining, jam nut are propped up in length-adjustable pull bar, angle, wherein, length-adjustable pull bar comprises: sleeve, be sleeved on the auris dextra ring bolt joint in sleeve one end and be sleeved on the left earrings screwed joint in the sleeve other end; This angle is propped up between the endoporus of outer ring by interference fit and auris dextra ring bolt joint of oscillating bearing and is installed together; This articulationes cylindroideus lining is arranged on left earrings screwed joint, and this jam nut is arranged on the two ends of sleeve, and auris dextra ring bolt joint and left earrings screwed joint is fixed on to the desired location of sleeve; Be articulated with respectively the mounting bracket of a upper and lower end fulcrum hinge on auris dextra ring bolt joint and left earrings screwed joint, the mounting bracket of this upper and lower end fulcrum hinge and the right angle rocking arm pivot joint of hatch cover are integrated, and at a parallelogram sturcutre of the common composition of Transverse plane.
The mounting bracket of described upper end fulcrum hinge is poor with the setting height(from bottom) of the mounting bracket of the fulcrum hinge that is positioned at rocking arm upper end, hatch cover right angle to be equated with the poor Δ h of setting height(from bottom) of the mounting bracket of hatch cover right angle rocking arm lower sustainer hinge with the mounting bracket of pull bar lower sustainer hinge; The mounting bracket of pull bar upper end fulcrum hinge equates with the transverse horizontal distance of the mounting bracket of hatch cover right angle rocking arm lower sustainer hinge with the mounting bracket of pull bar lower sustainer hinge with the transverse horizontal distance, delta L of the mounting bracket of rocking arm upper end, hatch cover right angle fulcrum hinge.
It is the spherical joint bearing that oscillating bearing is propped up at described angle.
Described articulationes cylindroideus lining is plain bearing.
The beneficial effects of the utility model:
(1) because the drag link mechanism hinge is installed fulcrum employing spherical joint bearing, and the degree of freedom (being commonly called as " universal hinge ") that the spherical joint bearing has three directions to rotate, like this, can open at hatch cover, in closing course, the lower hinge of pull bar is installed fulcrum can automatic position adjusting function, not there will be pull bar " stuck " phenomenon, guaranteed reliability and the safety of sea hatch cover opening/closing mechanism system;
(2) by right angle rocking arm and pull bar and upper and lower four hinges, installed during fulcrum formed the space parallel four-bar mechanism, wherein, the lower hinge of pull bar is installed fulcrum and is adopted the spherical joint bearing, like this, just processing and the setting accuracy of sea hatch cover opening/closing mechanism have been reduced, simultaneously, also be convenient to later maintenance and handling labor;
(3) what adopt due to the drag link mechanism two ends is left and right earrings screwed joint, like this, can carry out by the length of adjusting pull bar the running orbit of further adjusting cabin lid mechanism for opening/closing.And, after the pull bar length adjustment, directly use two left-right rotary nut lockings, easy to operate, mounting process is reasonable.
