Description

Mechanical lift platform
The utility model relates to a kind of lifting jacking system, particularly substation's maintenance mechanical elevating platform.
The most contact porcelain spares that need of maintenance in the substation, for guaranteeing safety, traditional all kinds of ladders do not allow directly to lean against on the porcelain spare.And bay-lift in the market is hydraulic pressure, crotch formula bay-lift, is made up of four parts such as bench board, crotch, actuating device and underframe, relies on platform both sides scissors mechanism, elects lifting with oil cylinder.Its from great, complex structure, need power supply, working service work capacity big.
Mechanical elevating platform of the present utility model partly is made up of bench board, major-minor ladder, column, bracing frame, hand push frame, driving device and chassis etc.Main ladder is positioned at the middle part, chassis, is framed structure, and four pillars are arranged, secondary ladder and main terraced structural similitude, and its two stressed pillars insert in two stressed pillars of main ladder, and two pillars paste mutually with two pillars in addition of main ladder in addition; Main terraced stressed pillar flexibly connects with the top that is fixed on the column on the underframe, and its lower end can be fixed on the column by bayonet lock; The hand push chord position links to each other with column in underframe one side, and bracing frame is positioned at the underframe opposite side, is used to support the major-minor ladder under the horizontal state; Driving device links to each other with secondary ladder through wirerope.
The utility model adopts mechanical drive, use, easy to maintenance, and it is from heavy and light, from height; Simple in structure, cost is low, is suitable in the substation that work capacitys such as general maintenance (light maintenance), maintenance are little, work-hours uses in short-term, also is applicable under the non-transformer situation such as field to use.After this device installs electrical equipment additional, but electric up-down also.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the running condition scheme drawing of this device.
Fig. 2 is the cutaway view of Fig. 1 along A-A.
Fig. 3 is the horizontal state scheme drawing of this device.
Referring to each accompanying drawing, this device partly is made of bench board 1, secondary ladder 2, main ladder 3, hand push frame 4, column 5, bracing frame 6, driving device 7 and chassis 8 etc.Main ladder 3 is positioned at 8 middle parts, chassis, is framed structure, and four pillars are arranged.Secondary ladder 2 and main terraced 3 structural similitudies, in two stressed pillars 13,14 of its two main ladders 3 of stressed pillars 9,10 insertions, two 11,12 two pillars 15,16 in addition of being made by angle steel equally with main terraced 3 of pillar by angle steel system paste mutually in addition.The stressed pillar 13,14 of main ladder 3 and the upper end flexible connection that is fixed on the column 5 on the chassis 8, its lower end then is fixed on the column 5 by bayonet lock 17.Bayonet lock 17 links to each other with position fixing handle 18 by steel cable 19, starts position fixing handle 18 and can open bayonet lock 17, and making the major-minor ladder is horizontal state from vertical state-transition.Bracing frame 6 is positioned at a side on chassis 8, and two soft backing plates 20,21 are arranged on it, is used to support the major-minor ladder under the horizontal state.The opposite side relative with bracing frame 6 is hand push frame 4, and its upper end links to each other with column 5, and the lower end is fixed on the chassis 8.
Bench board 1 relies on two pillars 22 that are inserted in the secondary terraced stressed pillar 9,10 to be connected with secondary ladder 2, and these two pillars constitute by the steel pipe that two joints flexibly connect.When the major-minor ladder is horizontal state, pull out a joint steel pipe, bench board can be made 90 degree rotary foldings, as shown in Figure 2.
Driving device is made up of flywheel 24, worm and gear 25, support 26, wirerope 27 and fixed pulley 28.Worm and gear 25 is positioned at the top of support 26, link to each other with flywheel 24, wirerope 27 1 ends link to each other with worm and gear 25, and the other end links to each other with terraced 2 bottoms of pair with two fixed pulleys that are positioned at 9,10 on secondary terraced top two stressed pillars through being fixed on the fixed pulley 28 on the chassis 8 and being positioned at 13,14 on main ladder bottom two stressed pillars.During work, bench board 1 bottom shore is all inserted secondary terraced stressed pillar 9,10, the rocking handle 29 on the rotary flywheel 24 drives worm and gear 25, affects wirerope 27, and the major-minor ladder is finished by the conversion of horizontal state to vertical state.When the major-minor ladder rises to the 8 one-tenth plumbnesss in chassis, the fixing main ladder two stressed pillars 13,14 of bayonet lock 17 coupler locks.Extract main terraced stressed pillar 13,14 upper arresting pins 30 this moment, be rotated further rocking handle 29, secondary ladder 2 just can stretch out from main ladder 3, after rising to required operating altitude, use clamp 31 and locating dowel pin 30 lockings between main terraced stressed pillar 13,14, the major-minor ladder can be stable mode of operation, and the staff just can be about major and minor ladder.
Four movable supporting legs 23 under the chassis 8 can be done 180 degree rotations in the horizontal direction, itself and the angle of horizontal direction, and the particular location of movable supporting legs can be located by locating dowel pin 32 controls when promptly working.At ordinary times, four movable supporting legs 23 are hidden in the both sides on chassis 8.Rely on cardan wheel 33 and rubber tire 34 under the chassis 8, but 360 degree rotations are done in mechanical elevating platform stage body original place.
