Task of the present utility model is to propose that a kind of rope capacity can meet high-lift lifting, and suspender has the flat rotation of water resistant Turn a kind of high-lift lifting device of ability.

Task of the present utility model, which is done in such a way that, is characterized in that：This lifting device is by hoisting mechanism and suspender structure Into the hoisting mechanism has a motor to connect two reductors respectively, and a reel, counter-jib point are connected on each reductor It is not corresponding with two reels to install, a counter-jib is corresponded to below each reel, there are two counter-jibs on each suspender, each hangs Point connection steel cable, the lower rope position of steel wire rope is separately positioned on the outside of reel.On the head and the tail output shaft of the motor Floating axle is connected with by shaft coupling, the floating axle is connected by shaft coupling with the high speed shaft on reductor, the reductor High speed shaft on the outside of be respectively arranged with a service brake, be connected to a reel on the slow-speed shaft on reductor, The reel is to use multi-lay winding reel, and deadman's brake is separately mounted to the afterbody of reel.Suspender is by two steel wires Rope is restricted from reel overlap is lower on the outside of reel again, passes through wire rope fixing device and steel wire rope stress on the lower end of steel wire rope Release device connects, and the other end of the steel wire rope stress release device is connected with counter-jib, and the counter-jib is hinged with fork It is hinged afterwards further through hinge and suspender beam body, suspender beam body centre position is hinged with suspension hook group, and suspension hook group can be in perpendicular Swing.

The utility model has the following effects that：The technical program is eliminated using stress release device triggers suspender to produce water The active force of flat rotation, service brake and safety are respectively adopted in the high speed shaft side of each reductor and each reel ends Brake, so as to ensure that the security performance of lifting device.

Embodiment

This lifting device is made up of hoisting mechanism 1-1 and suspender 2-2, and the hoisting mechanism has a motor 5 to connect respectively Two reductors, a reel is connected on each reductor, reach a motor and two reductors of driving and drive respectively simultaneously The operating of reel.It ensure that the synchronization of two reels, the installation corresponding with two reels respectively of the counter-jib on suspender, it is, A counter-jib is corresponded to below each reel, there are two counter-jibs on suspender, each counter-jib there are two suspension centres, and each suspension centre connects Steel cable is connect, this body structure of suspender can meet the adjustment effect of three dimensions all directions.

The hoisting mechanism 1-1 by shaft coupling 4 on the head and the tail output shaft of the motor 5 as shown in Fig. 2 be connected with floating Axle 6, the floating axle are connected by shaft coupling with the high speed shaft on reductor 2, the outside difference of the high speed shaft of the reductor It is provided with a service brake 1, a reel 3 is connected on the slow-speed shaft on reductor, the reel is using more Layer winding reel, deadman's brake 7 are separately mounted to the afterbody of reel, and the lower rope position of steel wire rope 8 is separately positioned on reel Outside, each reel one deadman's brake of corresponding installation, so as to ensure that the security of mechanism, motor is using double shaft electricity Machine.

As shown in Figure 3 and Figure 4, two counter-jibs on suspender correspond to reel installation, two counter-jibs to the suspender respectively Structure it is the same, the corresponding reel of each counter-jib, two ropes of reel are connected with same counter-jib respectively.Hanger structure Form is that 2 steel wire ropes are restricted from reel overlap is lower on the outside of reel again, and lower rope position 16 is as shown in Fig. 2 the lower end of steel wire rope 8 It is upper to be connected by wire rope fixing device 9 with steel wire rope stress release device 10, the steel wire rope stress release device it is another End is connected with counter-jib 13, and the counter-jib is be hinged further through hinge and suspender beam body 11 after being hinged with fork 14, suspender beam body 11 centre positions are hinged with suspension hook group 15, and suspension hook group can be swung in perpendicular, and suspension hook group is used for lift heavy, and steel wire rope stress is released Steel wire rope caused rotation stress in lifting process can be discharged in real time by putting device 10, and suspender 2-2 occurred levels direction is driven in elimination Rotating force, each counter-jib can adjust the error in length of two steel wire ropes on same reel, and suspender beam body can pass through The error in length of the steel wire rope between two reels is adjusted with the hinge that fork is formed.And the hanger structure of the technical program The regulation of three dimensions all directions can be met by being formed.
