Detailed description of the invention
In order to illustrate the technical solution of the utility model and technical purpose, below in conjunction with drawings and the specific embodiments, the utility model is described further.
A kind of hand wheel type Manual hoisting permanent magnet, comprise handwheel 1, prevent back lockable mechanism 2, permanent magnetic lifting device that transmission shaft 3, stop gear 4, reductor 5 and permanent magnet hoisting mechanism 6(can adopt patent No. CN201410326810) etc. constituent elements.
Described permanent magnet hoisting mechanism 6 comprises casing, the magnet being provided with two magnetic rotating shafts in described casing and being arranged in magnetic rotating shaft, and two magnetic rotating shafts are connected with the mouth of speed reduction gearing 5 by the transmission device being positioned at casing right-hand member, as shown in Figure 2.Described reductor 5 is arranged on the top of casing, and the input end of reductor 5 is connected with the handwheel 1 be arranged on the left of casing by transmission shaft 3.
Described handwheel comprises handwheel body and is arranged on the handwheel axostylus axostyle at handwheel body 1 center, handwheel axostylus axostyle is provided with and prevents back lockable mechanism 2 and axial lock locking mechanism.
Describedly prevent back that lockable mechanism 2 comprises interior fastener 8 and outer fastener 7, described interior fastener 8 is fixedly mounted on handwheel axostylus axostyle, and its external peripheral surface is provided with male splines; Described outer fastener 7 is in tubular, and its one end is fixed on mount pad by flange arrangement, and the end face of the other end is provided with the keyway suitable with the male splines of interior fastener 8, as shown in Fig. 3, Fig. 4, Fig. 5, Fig. 7.Described handwheel axostylus axostyle is connected with transmission shaft 3 by coupling body through behind the cylinder chamber of outer fastener 7, drives transmission shaft 3 to rotate.
Handwheel axostylus axostyle is slidably mounted in coupling body, make handwheel can driven forward, pull back, fitted shaft is to lockable mechanism effect.Described axial lock locking mechanism comprises the axle sleeve be enclosed within handwheel axostylus axostyle, and described axle sleeve is positioned at the inner core side of outer fastener 7, is fixed on mount pad.Handwheel axostylus axostyle is provided with the installation through hole of the radial through body of rod, and be provided with two steel ball bodies 1 and the spring between two steel ball bodies 11 in described installation through hole, the inner peripheral surface of described axle sleeve is provided with annular stop groove 12.
When handwheel body drives magnetic rotating shaft to forward magnetic region active position to, by handwheel driven forward, interior fastener 7 is pushed outer fastener 8 and blocks, prevent the phenomenon that generation is reversed because gyromagnetism is excessive.After handwheel driven forward puts in place, steel ball body 11 arrives the position of limited impression 12, and under the elastic force effect of spring, steel ball body 11 is ejected, and it ejects position and snaps in limited impression 12, and handwheel 1 can not be moved in the axial direction easily.
Described transmission shaft 3 is provided with stop gear 4, as shown in Fig. 2, Fig. 6, described stop gear 4 comprises the stop nut sliding block 9 and be arranged on transmission shaft 3 be enclosed within transmission shaft 3, and described transmission shaft 3 is provided with outside thread, and stop nut is fixed on the position of transmission shaft 3 setting.The described block 9 of sliding also is threaded connection with transmission shaft 3, slides to be stuck in bottom block 9 to be arranged in the slideway 10 at casing top.When transmission shaft 3 rotates, by the restriction of slideway 10, slide block 9 to move forward along transmission shaft 3, when it moves to stop nut place, handwheel drives magnetic rotating shaft just to forward best full magnetic potential to, and handwheel 1 because of slide block 9 be subject to stop also cannot be rotated further again, restart afterwards and prevent back that lockable mechanism and axial limiting mechanism carry out the locking of equipment package.The setting of stop gear 4 can effectively prevent handwheel 1 rotation from exceeding best full magnetic boundary line.
More than show and describe groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and the claimed scope of the utility model is defined by appending claims, specification sheets and equivalent thereof.
