The specific embodiment
A kind of light lifting appliance as shown in Figure 1, comprise and be horizontally set on the hanging beam 1 on front frame 10 and the after poppet 11 and be arranged on derricking gear on the hanging beam 1, described derricking gear comprises steel rope 3, described derricking gear comprises that also one is arranged on hanging beam 1 below and passes through roller 2 and cantilever beam 1 rolling bonded assembly arm 7, the front end of arm 7 is equipped with fixed pulley 1, the rear end of arm 7 is equipped with fixed pulley 29, on the arm 7 between fixed pulley 1 and the fixed pulley 29, be set with gig 8 by frame, the front end of steel rope 3 is walked around fixed pulley 29 successively and is connected with suspension hook 4 with fixed pulley 1, the rear end of steel rope 3 is mounted on take-up mechanism 12 on the described frame by gig 8, also be provided with the arm actuating device 6 that is connected with arm 7 rear ends on the described hanging beam 1, arm actuating device 6 is an electric pushrod mechanism, and take-up mechanism 12 is a unpowered take-up mechanism.
During the work of this lifting appliance three kinds of operating modes are arranged: lift by crane operating mode, translation operating mode and fall operating mode.(1) lifting operating mode, arm 7 moves to hanging beam 1 foremost by roller 2 under the promotion of arm actuating device 6, the distance between this moment suspension hook 4 and the front frame 10 farthest, during lifting, weight can not contact, collide with building; (2) translation operating mode, when weight rise winch to desired height after, can carry out the luffing operation by arm actuating device 6, arm actuating device 6 pulls back arm 7 along hanging beam 1, make the weight of slinging near building, realize the lifting of weight, and then push arm 7 to front end; (3) fall operating mode, by gig 8 steel rope 3 is emitted, empty suspension hook or the suspension hook that has a weight are steadily transferred.Arm actuating device 6 adopts electric pushrod mechanism, and this mechanism directly drives push rod along straight line push-and-pull arm 7 by motor, and it is seesawed.Electric pushrod mechanism simple in structure, the driving efficiency height, and also mode of operation is steady.
In above-mentioned three kinds of mode of operations, the folding and unfolding of steel rope 3 all realizes by the gig 8 that is connected with take-up mechanism 12, by gig 8 steel rope 3 is sent into take-up mechanism 12, or from take-up mechanism 12, steel rope 3 is pulled out, the utility model take-up mechanism 12 is unpowered take-up mechanism or dynamical type take-up mechanism.
Fig. 2 and Figure 3 shows that unpowered take-up mechanism, comprise that one is horizontally fixed on the axle 14 on gig 8 shells and rotates the closed cable dish 15 be arranged on the axle 14 by flange 13, closed cable dish 15 comprises the outer cover 15-2 that is sleeved on the inner core 15-1 on the axle 14 and radially is arranged on the inner core 15-1 outside, outer cover 15-2 is connected with inner core 15-1 with floor 15-4 by connecting panel 15-3, one side of closed cable dish 15 is provided with the 15-5 that opens for steel rope 3 turnover, and corresponding opening 15-5 place is provided with steel rope guide head 16.Be equipped with between 3 29, two bearings 3 29 of two bearings between inner core 15-1 and the axle 14 and be provided with spacer 30.
The principle of work of unpowered take-up mechanism is, when this lifting appliance is upwards mentioned suspension hook 4, gig 8 is done and is received the rope action, the steel rope 3 that is raised machine 8 withdrawals is through steel rope guide head 16, enter closed cable dish 15 by the opening 15-5 on the closed cable dish 15, because steel rope 3 has certain rigid and elasticity, therefore, the steel rope 3 that enters in the closed cable dish 15 is understood the thrust of also giving a tangential direction of outer cover 15-2 on the inwall of the outer cover 15-2 that withstands on closed cable dish 15, closed cable dish 15 is rotated along thrust direction, and the rotation of closed cable dish 15 is wrapped in steel rope 3 in the closed cable dish 15; Do when gig 8 and to put when action rope, steel rope 3 drives closed cable dish 15 backward rotation under the tractive of gig 8, and steel rope 3 is pulled out from closed cable dish 15.The rotation of above-mentioned closed cable dish 15 is all by the thrust or the pulling force of steel rope 3, and closed cable dish 15 self is not provided with actuating unit, thereby has simplified the structure of take-up mechanism 12, has alleviated weight, has reduced manufacturing cost.
Embodiment 2
The difference of present embodiment and embodiment 1 only is: take-up mechanism 12 is dynamical type take-up mechanism, and other structure is identical with embodiment 1.
Fig. 4 and Figure 5 shows that dynamical type take-up mechanism, comprise one by gig 8 rotating shaft 18 that drives and the open type cable dish 19 that is arranged in the rotating shaft 18, one end of rotating shaft 18 connects gig 8, the other end of rotating shaft 18 is connected with described frame by bearing 1, the middle part of rotating shaft 18 is provided with cable dish bindiny mechanism 21, open type cable dish 19 is connected with rotating shaft 18 by cable dish bindiny mechanism 21, open type cable dish 19 is provided with drg 22, be provided with the guide pipe 17 that an end has steel rope guide head 16 between gig 8 and the open type cable dish 19, one end of guide pipe 17 rotates by support 23 and is arranged on the described frame, and the other end of guide pipe 17 is equipped with the roller 25 that moves along guide plate 24.
As shown in Figure 6, cable dish bindiny mechanism 21 comprises the coaxial power-transfer clutch 21-1 and the sleeve 21-2 that is connected with power-transfer clutch 21-1 that is arranged in the rotating shaft 18, radially be provided with the terminal pad 21-3 of captiveing joint on the cylindrical of sleeve 21-2 with open type cable dish 19, the both sides of terminal pad 21-3 are provided with friction disc 21-4, the outside at a side friction disc 21-4 is equipped with nut 21-5, be provided with disk spring 21-6 between nut 21-5 and friction disc 21-4, between sleeve 21-2 and the rotating shaft 18 bearing 2 26 be installed.Power-transfer clutch 21-1 is an overriding clutch.
The principle of work of dynamical type take-up mechanism is, when this lifting appliance is upwards mentioned weight, gig 8 is done when receiving the rope action, the rotating shaft 18 that is connected with gig 8 provides power for this take-up mechanism, by overriding clutch is friction disc 21-4 unidirectional delivery moment of torsion, friction disc 21-4 drives open type cable dish 19 by terminal pad 21-3 and rotates, open type cable dish 19 is involved in the steel rope of being brought by gig 83, because steel rope 3 income velocities are less than the velocity of rotation of open type cable dish 19, therefore steel rope 3 has certain tensile force all the time when being involved in, and this tensile force is convenient to steel rope 3 proper alignment on the cable dish.When gig 8 is put the rope operation, rotating shaft 18 backward rotation, based on the characteristic of overriding clutch, open type cable dish 19 breaks away from rotating shaft 18 by overriding clutch and is connected.At this moment, be raised the steel rope 3 pulling open type cable dishes 19 that machine 8 involves and make backward rotation, the brake resistance that drg 22 is added on the open type cable dish 19 makes steel rope remain certain tensile force, and this tensile force is emitted steel rope reposefully from open type cable dish 19.When the operation of retractable rope, with the position difference that steel rope 3 twines on the cable dish, the rear end of guide pipe 17 can swing by the rolling of roller 25, thereby has improved the servo-actuated of steel rope 3 when folding and unfolding.
The limit switch 1 that is arranged on gig 8 front end steel rope import and exports is the safety guard-safeguard facility with the limit switch 2 28 that is arranged on steel rope guide head 16 places.When gig 8 receipts ropes are excessive, the wire clips 8 that is positioned at steel rope 3 front ends will promote a recoil spring and at first contact with limit switch 1, make limit switch one 27 actions, and outage is immediately shut down; Put rope excessively when gig 8, the rear end of steel rope 3 is connected with the cable disk detachment, by limit switch 2 28 o'clock, limit switch 2 28 actions, and outage shutdown immediately, thus prevent the accident generation.
