The specific embodiment

Referring to Fig. 1, the utility model cabin interior operated lifter comprises lifting support 1, lifting arm 2, handles seat 3 and towing bracket 4 mechanism of twisting rope 5 and hauling rope 6.Lifting support 1 is removably mounted on the ceiling board 7 of cabin, lifting arm 2 is installed in rotation on the lifting support 1, handle the top that seat 3 is installed in rotation on lifting arm 2, towing bracket 4 is installed in the top, cabin of cabin, mechanism of twisting rope 5 can be installed in (as shown in this embodiment) on the towing bracket 4, also can be installed on the lifting support or be installed in the masthead of lifting arm, one end of hauling rope 6 is wound on the mechanism of twisting rope 5, and the other end is walked around towing bracket 4 backs and linked to each other with

lifting arm

2 or 3 tractions of manipulation seat.

Referring to Fig. 2, cooperation is referring to Fig. 1, lifting support 1 in the utility model comprises the base 11 and the seat of honour 12, base 11 usefulness bolts or other detouchable fastener are fixedly mounted on the ceiling board of cabin, the seat of honour 12 is installed on the base 11 can do the horizontal direction rotation by drive mechanism, adopt revolute pair to be connected between the seat of honour 12 and the lifting arm 2, the seat of honour is provided with and links to each other with lifting arm 2 and the transverse axis 13 of confession lifting arm rotation.The power that is used to drive seat of honour rotation can come from propulsions source such as hydraulic pressure, electric power, machinery.Figure 2 shows that an embodiment of driver train, this driver train comprises the HM Hydraulic Motor 111 that is installed on the base plate, is installed in the miniature gears 112 on HM Hydraulic Motor 111 output shafts, the big gear wheel 113 that links to each other with miniature gears 112 engagements, big gear wheel 113 is fixed on the seat of honour 12, and the seat of honour 12 also is bearing on the base by a center shaft 121.Drive miniature gears 112 rotations by HM Hydraulic Motor 111 in the work, miniature gears 112 drives big gear wheel 113 rotations, thereby drives horizontal direction is made at the seat of honour 12 around center shaft 121 rotation.

Continuation is referring to Fig. 1, and the towing bracket 4 in the utility model comprises mounting base 41, tubular axle 42 and fixed pulley 43.Mounting base 41 is fixedly mounted in the default mounting hole in top, cabin, tubular axle 42 is installed in rotation in the mounting base (can by mounting base itself is made bearing arrangement spare or bearing installation is realized) on mounting base, fixed pulley 43 is installed in the bottom of tubular axle by sheave shaft 431 (cooperating referring to Fig. 3).

In order to make trailer coupling 4 and lifting support 1 keep rotation synchronously, the utility model can be installed on the tubular axle 42 in lifting support 1 and the towing bracket 4 and make the two keep the sensor control mechanism of rotation synchronously.The sensor kind is a lot, is example with the rotary encoder, and it can be installed on the S. A., when axle rotates, sends a series of pulses, and to measure its anglec of rotation, controller can make the two take this to keep synchronous rotation according to comparing the error between the two and compensating it.Another kind makes mode that trailer coupling 4 and lifting support 1 keep rotation synchronously as shown in Figure 3, Figure 4, promptly increases by one group of hauling rope arrangement for guiding 9, and this hauling rope arrangement for guiding 9 comprises that two transverse arms 91, pulley base 92 and two draw pulley 93.The inner of two transverse arms 91 is installed in rotation on the sheave shaft 431 of fixed pulley 43 both sides in the tubular axle 42, and its axial location can limit with jump ring 94 or other positioning element.The outer end that pulley base 92 is connected two transverse arms is linked to be integral body with two transverse arms, draws pulley 93 tight adjacent being installed in the pulley base for two.Allowing hauling rope 6 walk around fixed pulley 43 back draws to pass with lifting arm 2 between the pulley 93 again or handle seat 3 from two and links to each other.The setting of hauling rope arrangement for guiding 9 makes the centre of gration that pulley center departs from tubular axle 42 greatly of drawing of drawing rope, when elevator Cuo 1 rotation, can make the tubular axle 42 of hysteresis obtain an additional torque, owing between tubular axle 42 and the mounting base 41 less friction is only arranged, makes tubular axle 42 do synchronous rotation around the rotation of elevator Cuo 1 with the lifting arm end ring.

Lifting arm 2 of the present utility model has two ends, the seat of honour of its bottom and lifting support 1 constitutes revolute pair, and when the lifting arm top and when handling seat 3 and being subjected to the traction of towing bracket 4, lifting arm 2 can rotate by the transverse axis 13 on the seat of honour, thereby change its elevation angle, drive and handle seat 3 liftings; Simultaneously, when the seat of honour rotated on base, the azimuth of lifting

arm

2 and 3 pairs of lifting supports 1 of manipulation seat changed thereupon.Lifting arm 2 tops with handle seat 3 and form revolute pairs, and the center position of revolute pair is higher than the center-of-gravity position of handling seat and load,, can be made like this and handle an end of 3 and remain level to keep handling the level of seat by the center of gravity location.Another method that makes the end maintenance level of handling seat 3 as shown in Figure 5, adopt two fixed pulleys and two hauling ropes, two fixed pulleys 43 are installed in the bottom of tubular axle, two hauling ropes 6 are connected on the manipulation seat 3 from two fixed pulleys, 43 parallel drawing respectively, form a parallelogram sturcutre, make lifting arm 2 tops and handle 3 center of turn of forming revolute pairs to be between two parallel liness of hauling rope, can adjust the length of rope, make the seat maintenance level of handling.When two ropes of synchronous folding and unfolding, lifting arm can make the seat maintenance level still of handling thereupon lifting.Can also adopt four fixed pulleys 43 and four hauling ropes 6, four coaxial in twos bottoms that are installed in the tubular axle of fixed pulley 43, four hauling ropes 6 are connected on the manipulation seat 3 from four fixed pulleys, 43 parallel drawing respectively, form two parallelogram sturcutres, make the seat maintenance level of handling.Certainly also can force to adjust the horizontality of handling seat, make its maintenance level by artificial direct control.

Lifting arm in the utility model can be integral stem or expansion link, and when lifting arm was expansion link, it was flexible to be provided with drive mechanism.When lifting arm was expansion link, owing to reasons such as deadweights, the bending of bar was inevitable, and in order to address this problem, the utility model can have the hauling rope of drawing from trailer coupling to be attached thereto on bar sections at different levels.With appropriate balance gravity, reduce the bending of lifting arm single-piece.

Above-mentioned described hauling rope is meant the rope that can bear tractive force in the utility model, and it comprises the rope/band of chain, various materials and wirerope etc.

The situation that local delamination is arranged on the limit in the cabin of considering, be not easy to handle seat 3 near the bulkhead 7 between two-layer, an embodiment of the present utility model is provided with one section downward bending segment 21 at the front end of lifting arm 2, and hauling rope 6 is connected this bending segment with on the interior lifting arm, as shown in Figure 6.This structure can guarantee to handle seat 3 can be successfully near the bulkhead 10 between two-layer, convenient construction personnel's operation.

Each part detachable of the utility model cabin interior operated lifter is opened, and convenient narrow window from cabin is transported in the cabin to be installed, and transports with the back single parts of detachable one-tenth, recovers the cabin original state.For the installation of trailer coupling, generally be to go up perforate at ceiling board (deck), seal up with cover plate at ordinary times, lay down cover plate during use and install.For some ship type, also can select the edge of large-scale hatch or other that suitable height is arranged and can bear downward pulling force part towing bracket is installed.
