Detailed description of the invention
(the first embodiment)
Below, the first embodiment of the present invention is described in detail with reference to accompanying drawing.Herein, an example of application electric-driven chain block of the present invention.As shown in FIG. 1 to 3, the electric-driven chain block 10 of present embodiment has the framework 11 as electric-driven chain block main body.The side of framework 11 is provided with motor frame 11a, opposite side is provided with gear case 11b.Be provided with to link up with at the upper lateral part of this framework 11 and namely go up suspender 12, electric-driven chain block 10 is suspended in Work places by suspender on this 12.The downside of the upper suspender 12 in framework 11 is provided with sprocket wheel 13 in mode shown in dotted lines in Figure 2.Sprocket wheel 13 is rotatably supported relative to framework 11.This sprocket wheel 13 is wound with load bearing chain 14, one end of load bearing chain 14 is provided with lower draw-bar and namely descends suspender 15, weight and lift heavy are hung on this lower suspender 15.So, in the following description, sometimes the one end of the load bearing chain 14 being provided with lower suspender 15 is called " lower end ", the other end is called " upper end " is distinguished.Certainly, this difference is difference for convenience of description.
When sprocket wheel 13 shown in Fig. 2 is driven in rotation, load bearing chain 14 reels and rises or winding decline.Winding with load bearing chain 14 rises or winding declines, and the lift heavy hung on lower suspender 15 is moved upward or moves downwards.That is, lift heavy is hung to rise or hang and is fallen.As depicted in figs. 1 and 2, the chain collector for receiving the load bearing chain 14 that winding rises and chain bucket 16 are installed on the frame 11.Chain bucket 16 is offsettingly arranged on the rear side of framework 11 as shown in Figure 2.When lift heavy is hung and rises, the load bearing chain 14 that winding rises is admitted in chain bucket 16, and when lift heavy is hung and falls, load bearing chain 14 is drawn out of in chain bucket 16.As depicted in figs. 1 and 2, electric-driven chain block 10 is connected with operation inputting part 18 by cable 17.By being operated in the rising switch and decline switch that operation inputting part 18 arranges by operator, carry out vertical motion and the down maneuver of load bearing chain 14.
As shown in Figure 3, sprocket wheel 13 is fixed on the sprocket shaft 21 of hollow, and this sprocket shaft 21 is rotatably arranged in framework 11.In motor frame 11a, be configured with electrical motor 22, the output shaft 23 of electrical motor 22 is given prominence to laterally from the both ends of the surface of electrical motor 22.The nose portion 23a of the side of output shaft 23 is arranged on by bearing and is fixed on the back plate 24 of motor frame 11a, and this back plate 24 is provided with magnet stopper 25.
Magnet stopper 25 has coil 26, is relatively fixed with rotating disc 27 at the nose portion 23a of output shaft 23 and back plate 24.In addition, between rotating disc 27 and coil 26, being configured with can close to the arresting disc 28 away from movement relative to them.Arresting disc 28 is applied towards the elastic force in the direction of rotating disc 27.When arresting disc 28 presses to rotating disc 27 by elastic force, arresting disc 28 and rotating disc 27 are close on back plate 24, and magnet stopper 25 becomes arrested state, and output shaft 23 is locked.On the other hand, when being energized to coil 26, arresting disc 28 is attracted by magnetic force opposing elastic force, and arresting disc 28 leaves from rotating disc 27, and magnet stopper 25 becomes the release position of the rotation allowing output shaft 23.
As shown in Figure 3, the nose portion 23b of the output shaft 23 of electrical motor 22 links with the axle drive shaft 31 of inside of the sprocket shaft 21 being rotatably assembled in hollow.Axle drive shaft 31 is linked with miniature gears 33 by the slip clutch 32 arranged in gear case 11b, and this miniature gears 33 engages with the big gear wheel 35 arranged on deboost axle 34.The speed reduction gearing 36 rotation of axle drive shaft 31 deceleration transmitted to deboost axle 34 is formed by this miniature gears 33 and big gear wheel 35.Deboost axle 34 is linked with sprocket shaft 21 by the mechanical brake 37 installed in the outside of sprocket shaft 21, and the speed reduction gearing 36 that is rotated through of the output shaft 23 of electrical motor 22 slows down and transmits to sprocket shaft 21.
Mechanical brake 37 has the brake disc 40 in the threaded shank 38 comprising drum and the dish portion 39 arranged integratedly in an end of this threaded shank 38, and brake disc 40 is fixed on sprocket shaft 21.Mechanical brake 37 braking torque that realization is larger compared with the magnet stopper 25 by electromagnetic force work.Thus, even if apply large load by lift heavy to sprocket wheel 13 under the state making electrical motor 22 stop, the rotation of sprocket wheel 13 also reliably can be limited.
Slip clutch 32 has the clutch plate 41 installed on axle drive shaft 31 and the clutch plate 42 installed on miniature gears 33.When being applied with excessive load to sprocket wheel 13, the clutch plate 41,42 of slip clutch 32 slides, and cuts off the rotation transmission from miniature gears 33 to axle drive shaft 31.Thereby, it is possible to prevent from exceeding the lift heavy of predetermined weight hang liter.In addition, between clutch plate 41,42, clutch-lining is configured with.
The outer peripheral face of the threaded shank 38 of mechanical brake 37 is formed with external screw thread 38a, and the negative thread 43a of spragging gear 43 is threaded with this external screw thread 38a.This spragging gear 43 engages with the link gear 44 arranged on deboost axle 34, and the output of axle drive shaft 31 is transmitted to spragging gear 43 by deboost axle 34.Ratchet 45 (ratchet wheel) is rotatably installed between spragging gear 43 and dish portion 39.Spragging gear 43 is when the direction close to dish portion 39 rotates relatively, and spragging gear 43 and ratchet 45 are close to, by ratchet 45 by brake disc 40 and spragging gear 43 stop.On the other hand, spragging gear 43 is relative to brake disc 40 when the direction of removing stop rotates relatively, and brake disc 40 is removed with the stop of spragging gear 43, and mechanical brake 37 becomes release position.Like this, when spragging gear 43 rotates relatively relative to brake disc 40, spragging gear 43 moves between stop position and releasing position in the axial direction relative to brake disc 40.The position that spragging gear 43 leaves from dish portion 39 is limited by block 46.
There is the mechanical brake 37 of said structure, though suspend in midair have lift heavy state under electrical motor 22 is quit work, also limit sprocket shaft 21 rotate because of the load applied sprocket wheel 13.In addition, mechanical brake 37 prevents from transmitting reverse torque because of lift heavy to electrical motor 22 when being suspended in midair lift heavy by electrical motor 22.
As depicted in figs. 1 and 2, load bearing chain 14 is formed by the multiple chain links linked, and the attitude of adjacent chain link staggers mutually in right angle orientation.Under the state that load bearing chain 14 is hung around on sprocket wheel 13 (Fig. 2), the half of multiple chain links forming load bearing chain 14 is that second half is towards the second chain link 14b of the transverse direction in the direction along rotary middle spindle relative to the rotary middle spindle of sprocket wheel 13 towards the first chain link 14a of the longitudinal direction of right angle orientation.That is, load bearing chain 14 is formed by the first chain link 14a alternately arranged and the second chain link 14b, and the first adjacent chain 14a and the attitude of the second chain 14b stagger mutually in right angle orientation.So, in the following description, sometimes the first chain link 14a is called " vertical chain link 14a ", the second chain link 14b is called " cross chain joint 14b " distinguishes.Certainly, this difference is difference for convenience of description.
As depicted in figs. 1 and 2, the lower end of load bearing chain 14 is provided with lower suspender 15, on lower suspender 15, is provided with the operating portion 50 of the not shown limit switch that the bottom for operating in framework 11 is arranged.Operating portion 50 rises with the winding of load bearing chain 14, reeling declines and be together elevated with lower suspender 15.Operating portion 50, when the winding rising length of load bearing chain 14 reaches specified length, contacts with the not shown limit switch being arranged at framework bottom, is boosted by this limit switch.After limit switch is boosted, independently cut off with the operating conditions of operation inputting part 18 and the electric power of electrical motor 22 (Fig. 3) is supplied, the vertical motion of load bearing chain 14 is stopped.In the present embodiment, impact when contacting with limit switch to make operating portion 50 absorption, forms operating portion 50 with wind spring.So, in the following description, operating portion 50 is called " wind spring 50 ".
Upper plate 51 and lower plate 52 is welded with up and down respectively, the through upper plate 51 of load bearing chain 14, wind spring 50 and lower plate 52 and link with lower suspender 15 at wind spring 50.
As shown in Figure 4, being provided with on wind spring 50 can along the lubricant applying mechanism 60 of load bearing chain 14 movement.As shown in Figure 4, Figure 5, lubricant applying mechanism 60 have configure around load bearing chain 14 lubricant impregnation body 61 (Fig. 5), coverage lubricant impregnating 61 outer peripheral face exterior body 62 and by one end of exterior body 62 block lid 63 (Fig. 4).
Lubricant impregnation body 61 shown in Fig. 5 is made up of lamination coatings such as porous material or cloth such as sponges, absorbs and keeps the lubricant such as lubricating oil or grease.Lubricant impregnation body 61 is substantial cylindrical, is formed with the through hole 64 that the moving direction along lubricant applying mechanism 60 extends within it.In other words, be formed with load bearing chain 14 in the inner side of lubricant impregnation body 61 by namely through through hole 64, lubricant impregnation body 61 can move along load bearing chain 14.The first slot 64a that this through hole 64 is passed through by vertical chain link 14a and intersect with the first slot 64a, cross chain saves the second slot 64b that 14b passes through and is formed as criss-cross.That is, the first slot 64a is orthogonal with the second slot 64b.
At the intersection point of the medial surface of the first slot 64a and the medial surface of the second slot 64b, be integrally formed multiple juts 65 that the center of oriented through hole 64 is outstanding.4 juts 65a, 65b, 65c, 65d are formed with in present embodiment.Specifically, another relative with clipping this center of the center that clips through hole 64 relative a pair jut 65a, 65b is formed with to jut 65c, 65d.That is, in the inner side of through hole 64,4 juts 65a, 65b, 65c, 65d configure with 90 degree of intervals.In other words, a pair jut 65a, 65b deflect+45 degree relative to vertical chain link 14a, relative to cross chain joint 14b deflection-45 degree.On the other hand, another deflects-45 degree to jut 65c, 65d relative to vertical chain link 14a, relative to cross chain joint 14b deflection+45 degree.Herein ,+direction refers to clws direction in the paper of Fig. 5, and-direction refers to the direction of conter clockwise.
The front end of each jut 65 configured as described above contacts with load bearing chain 14.On the other hand, in lubricant impregnation body 61, the lubricant of dipping is supplied to each jut 65 by capillarity.Thus, lubricant is applied by each jut 65 pairs of load bearing chains 14.Details content about lubricant applying is described below.
As shown in Figure 4, Figure 5, the outer peripheral face of lubricant impregnation body 61 is covered by roughly cylindric exterior body 62.Exterior body 62 is formed by synthetic resin or cloth etc., has flexibility.Therefore, deform when exterior body 62 is pressed, with this distortion, the lubricant impregnation body 61 (Fig. 5) being positioned at the inner side of exterior body 62 is crushed.That is, lubricant impregnation body 61 elastic deformation can be made by pressing exterior body 62, wittingly jut 65 be supplied to the lubricant of dipping in lubricant impregnation body 61.In addition, the lubricant impregnation body 61 comprising jut 65 also can be made temporarily to increase with the area of contact of load bearing chain 14.In addition, when removing the pressing for exterior body 62, exterior body 62 recovers original shape because of at least one in the recuperability of lubricant impregnation body 61 and the recuperability of self.
As shown in Figure 4, the upper opening portion (not shown) of exterior body 62 is blocked by discoideus lid 63.That is, the upper surface of the lubricant impregnation body 61 shown in Fig. 5 is covered by the lid 63 shown in Fig. 4.This lid 63 is formed the second through hole 66 that load bearing chain 14 is through.This through hole 66 has the shape roughly the same with the through hole 64 formed on lubricant impregnation body 61, is communicated with through hole 64.That is, 2 through holes 64,66 one-tenth be integrated and form 1 breakthrough part.
Then, illustrate that with lubricator applying mechanism 60 pairs of load bearing chains 14 apply the method for lubricant.When lubricant applying mechanism 60 pairs of load bearing chains 14 shown in waiting with Fig. 1 apply lubricant, operator makes lubricant applying mechanism 60 move along load bearing chain 14.When lubricant applying mechanism 60 moves along load bearing chain 14, the front end of the jut 65 arranged in lubricant impregnation body 61 shown in Fig. 5 and load bearing chain 14 moving contact are also mobile.That is, slide in the front end of jut 65 on load bearing chain 14, applies lubricant thus to load bearing chain 14.Particularly, in the present embodiment that multiple jut 65 configures as described above according to the relation with chain link 14a, 14b, can to vertical chain link 14a and cross chain save the wipe contact portion of 14b or its near effectively apply lubricant.And, when lubricant applying mechanism 60 is moved along load bearing chain 14, use ladder or lift car as required.In addition, lubricating oil applying mechanism 60 also can be arranged on the bottom of central frame 11.In the embodiment of bottom lubricating oil applying mechanism 60 being arranged on central frame 11, even if do not move lubricating oil applying mechanism 60, also lubricating oil applying mechanism 60 pairs of load bearing chain 14 coating lubricants can be passed through.That is, operator operates rising switch and decline switch, when performing vertical motion or the down maneuver of load bearing chain 14, when load bearing chain 14 is by lubricating oil applying mechanism 60, to load bearing chain 14 coating lubricant.In this situation, lubricating oil applying mechanism 60 is made releasably to be arranged on lower housing portion.
Lubricant applying mechanism 60 when not using, on the upper plate 51 being positioned in wind spring 50 (Fig. 1, Fig. 4).Now, the lower opening portion (not shown) of exterior body 62 is blocked by the upper plate 51 of wind spring 50.Meanwhile, the lower surface of the lubricant impregnation body 61 shown in Fig. 5 is covered by the upper plate 51 shown in Fig. 4 etc.That is, the upper plate 51 of wind spring 50 also plays the effect of the base plate of one end of blocking exterior body 62.
In addition, when the amount of the lubricant of dipping decreases in the lubricant impregnation body 61 shown in Fig. 5, the lid 63 supply lubricant shown in Fig. 4 can be opened.Lid 63 is only positioned in the edge in the upper opening portion of exterior body 62, unfixing.Therefore, when picking up lid 63, the upper opening portion of exterior body 62 is opened, and the upper surface of lubricant impregnation body 61 (Fig. 5) is exposed, and can carry out the supply of lubricant.Certainly, if can remove fixing as required, exterior body 62 also can be made to fix with lid 63.
Moreover the height (H) of the lubricant applying mechanism 60 shown in Fig. 1 is the diameters (D) shown in 30mm, Fig. 5 is 55mm.Certainly, this numerical value is an example, and height (H) and the diameter (D) of lubricant applying mechanism 60 can suitably change.Thus, correspondingly change lubricant impregnation body by the diameter with load bearing chain, load bearing chain coating lubricant that also can be different to diameter.But, be provided with in the present embodiment of lubricant applying mechanism 60 on wind spring 50, when the winding rising length of load bearing chain 14 reaches specified length, by lubricant applying mechanism 60 by above-mentioned limit switch jack-up.In other words, the maximum winding rising length of load bearing chain 14 is subject to the impact of the height (H) of lubricant applying mechanism 60.So, on the basis of maximum winding rising length considering load bearing chain 14, preferably determine the height (H) of lubricant applying mechanism 60.
