Embodiment
Now embodiment of the present utility model is elaborated in conjunction with diagram.
As shown in Figure 1, consult Fig. 2 simultaneously.In the preferred embodiment of the drive unit of a kind of draw out switchgear electrical equipment of the utility model, this drive unit is placed in the main body frame 2, is connected with Switch main body 1 simultaneously.
This drive unit comprises guiding mechanism 3, is fixed in the main body frame 2 and transmission mechanism that is connected with Switch main body 1 and the drive unit that is connected with transmission mechanism; Transmission mechanism can be converted into the rotation of self moving of body switch 1.
This drive unit drives above-mentioned transmission mechanism, and driving switch body 1 skids off in 2 along guiding mechanism 3 from main body frame.Owing to adopted drive unit, transferring power is come by transmission mechanism again in the centre, skid off in 2 along guiding mechanism 3 from main body frame thereby can drive this 1 body of switch reliably, reposefully, be particularly conducive to the extraction and the closed procedure of the Switch main body of larger volume and weight.
As shown in Figure 3, further, transmission mechanism comprises Left Drive mechanism 4 and right transmission mechanism 5 again, Left Drive mechanism 4 and right transmission mechanism 5 are the internal faces that are symmetricly set on main body frame 2, promptly on the left and right sides plate of main body frame 2.Being symmetrical arranged of transmission mechanism can make the stressed more even of body switch 1, thereby motion is more steady.
Preferably, Left Drive mechanism 4 and right transmission mechanism 5 include the swing arm 6 that is rotatably mounted on the main body frame 2, shift fork 7 (see figure 4)s that are connected by camshaft bearing 612 (see figure 6)s with swing arm 6, coaxial hard-wired to changeing assembly 8 with shift fork 7; Wherein, be connected with Switch main body 1 changeing assembly 8, and the rotation of self can be converted into moving of Switch main body 1.
Because Left Drive mechanism 4 and right transmission mechanism 5 are symmetrically arranged, narration for convenience, therefore above-mentioned swing arm 6 is divided into left swing arm 61 and right swing arm 62, is understandable that, above-mentioned shift fork 7 and to two shift forks about changeing assembly 8 and also should comprising and about two pairs change assemblies.
Above-mentioned two swing arms connect to realize being synchronized with the movement of Left Drive mechanism 4 and right transmission mechanism 5 by square shaft 9.Can draw from figure, two swing arms all have the square shaft hole, the two ends of square shaft 9 respectively from about pass the square shaft hole of two swing arms and rotatable with respect to two swing arms.In preferred embodiment of the present utility model, the two ends of square shaft 9 are connected with the biside plate of main body frame 2 by square shaft mount pad (not shown), and square shaft 9 is rotatable with respect to above-mentioned square shaft mount pad.
Left side swing arm 61 can link with drive unit, therefore, when under the drive of swing arm 6 at drive unit swing taking place, can drive the shift fork 7 that connects by camshaft bearing 612 with it simultaneously, is driven changeing the rotation of assembly 8 by shift fork 7.
Further, above-mentionedly comprise by fixing the going up of holder 10 and main body frame 2 side plates changeing assembly 81 and coaxial hard-wired down to changeing assembly 82 with shift fork 7 to changeing assembly 8.Holder 10 is fixedlyed connected with the side plate of main body frame 2 by screw, can rotate synchronously with shift fork 7 changeing assembly 82 down.
Above-mentioned go up to change assembly 81 comprise again to change gear 11 and with last to commentaries on classics gear 811 coaxial hard-wired epirelief wheel plates 812, similarly, down to change assembly 82 comprise down to change gear 821 and with down to changeing gear 821 coaxial hard-wired lobe plates 822 down, and go up changeing gear 811 and being meshing with each other to changeing gear 821 down.Epirelief wheel plate 812 and following lobe plate 822 are equipped with driver slot 83 (see figure 4)s, and driver slot 83 cooperates with camshaft bearing 11 (see figure 2)s that are fixed on Switch main body 1 one sides.By this driver slot 83 self rotation is changed into the mobile of Switch main body 1 to changeing assembly 8.It should be noted that, be intended to change into moving of Switch main body 1 with rotating this forms of motion to changeing assembly 8, therefore, this structure also can adopt slider-crank mechanism or cam mechanism to replace, but above two kinds of mechanisms are than the rotation to the commentaries on classics gear, and the stationarity of motion is relatively poor.
Preferably, above-mentioned drive unit comprises operating body, is axially fixed in the main body frame 2 and the screw rod 12 that is connected with operating body, is set in the nut slider assembly 13 on the screw rod 12.Wherein, screw rod 12 is axially fixed in the main body frame 2 via two holders (not marking among the figure), and screw rod 12 can drive rotation by operating body in holder, but axially cannot be moved.Nut slider assembly 13 can move along the screw thread of screw rod 12 rear ends, and this nut slider assembly 13 is intended to promote left swing arm 61 swings.
As shown in Figure 5, above-mentioned nut slider assembly 13 be provided with camshaft bearing 131, with the nut 132 of the threaded engagement of screw rod 12 and be fixed on main body frame 2 on the slide rail 133 that cooperates of slide track seat 14.This slide track seat 14 is to be fixed on the left plate of main body frame 2, by cooperating of slide rail 133 and slide track seat 14, can guarantee nut slider assembly 13 steadily moving along screw rod 12.
