The method to set up of fall way is a lot, and a kind of method is to be made of hollow bushing 60 and elevating lever 606 two parts.The regulating wheel 604 that hollow bushing 60 tops are provided with external screw thread 601 and match with external screw thread 601, axial groove 605 (also being provided with corresponding axial groove on the tube wall on this groove opposite) is set on the tube wall of hollow bushing 60, regulating wheel 604 outer peripheral faces are provided with a circle adjusting rod hole 6041, it is the blind hole form, be used to admit adjusting rod 602, select to use for the operator.In conjunction with Fig. 3, elevating lever 606 is inserted in hollow bushing 60 pipes from top to bottom, axially-aligned one and is arranged radially pin-and-hole 6061 on its body of rod, and it is a through hole, this radially pin-and-hole 6061 be used to admit alignment pin 603, can be during use according to the height needs, alignment pin 603 is inserted on the radially pin-and-hole 6061 of differing heights, when revolving on the regulating wheel 604, pushing tow alignment pin 603 makes elevating lever 606 up, otherwise elevating lever 606 is descending.The upper end of elevating lever 606 is step-like, forms union end.
Another kind method is to adopt the hydraulic lifting pipe, reaches the lifting purpose.Certainly, also can adopt mode such as pneumatic, electronic to realize lifting.
In conjunction with Fig. 4-Fig. 6.Substrate 230 is that a square is dull and stereotyped, and its four jiaos are provided with through hole 232, and a screw sleeve 231 is fixed in the welding of through hole 232 belows, and screw sleeve 231 is consistent with the internal diameter of substrate through-hole 232, and the internal thread of screw sleeve 231 is used to admit corresponding adjusting screw(rod).The upper end of elevating lever 606 and substrate 230 are fixedly connected, its mode is: a sleeve 234 that is used to admit elevating lever 606 has been fixed in the welding of substrate 230 lower planes middle part, have an elevating lever fixing threaded hole 2341 on the barrel of sleeve 234, after when elevating lever 606 upper end step stretch into this sleeve 234 with the upper part in, both are fixedly connected through elevating lever fixing threaded hole 2341 by elevating lever hold-down nut 6062, after unscrewing elevating lever hold-down nut 6062, elevating lever 606 can rotate in hollow bushing 60, by twitching the radially pin-and-hole 6061 that to select differing heights on the elevating lever 606 up and down, alignment pin 603 is inserted wherein fixing.
The platform body is made up of lower plate 240, middle plate 220, upper plate 210 from lower to upper.
In conjunction with Fig. 7-8.Lower plate 240 is square plates of a, shape 230 onesize with substrate, be close to substrate 230 tops during assembling, on its four jiaos with 230 4 jiaos of substrates on through hole 232 phase positions coupling be provided with it is concentric but the through hole 241 that the aperture is less, the reason of She Zhiing is to need to consider for horizontal adjusting like this, and this also can relate to when following description level(l)ing device.The last plane of lower plate 240 is provided with a sagittal nut 242, and to adjusting screw(rod), this can further relate to during to adjusting device in following descriptions front and back before and after this nut 242 was used for admitting.
In conjunction with Fig. 9-11.Middle plate 220 is shelved on lower plate 240 tops, is the comparatively complicated flat board of a block structure, and it is plane that body shape also is, and size is consistent with lower plate 240, but lower plane is provided with for the annex that all around adjusting device is used is installed thereon.Plane annex is for installing left and right adjusting device usefulness on it, be provided with about two to slide rail 222, two one slide rails 222 in the middle of be provided with in the same way a nut 302; The lower plane annex is used for adjusting device before and after installing, be provided with a sagittal U-shaped plate 221 at its both sides and substrate 230 and lower plate through hole 241 corresponding positions, have sagittal stroke groove 2211 on the U-shaped plate 221, and in the rear portion solid welding one front and back adjusting screw(rod) end cover 224 (these can further relate to during adjusting device before and after being described below), upper plate 210 is shelved on the last plane of lower plate 210 through left and right sides U-shaped plate 221.
In conjunction with Figure 12-14.Upper plate 210 is arranged in plate 220 tops, is made of big or small and the top board that middle plate 220 is roughly consistent and four blocks of side plates that are positioned at whole platform assembly periphery, and the adhered insulating barrier 20 that is provided with in plane on the top board is to guarantee to install safety; The front side board 211 of four sides side plate is provided with left and right sides stroke groove 211a, right plate 2112 is provided with fixing hole 2112a and mounting groove 2112b, makes device for installing and adjusting and uses.Have the space between upper plate 210 and the middle plate 220, be used to install the left and right adjusting device.Upper plate 210 lower planes and middle plate slide rail 222 corresponding sections are provided with chute 212, and upper plate 210 can be horizontally slipped, and upper plate 210 left sides are provided with screw rod cover 303.
The total thinking of the design of three adjusting devices is: level(l)ing device is a reference plane with substrate 230, by screw rod the whole platform body on its top is adjusted; The front and back adjusting device is a reference plane with lower plate 240, it is produced with top move forward and backward; The left and right adjusting device is a reference plane with middle plate 220 then, makes it produce move left and right with top, thereby comprehensively finishes the level of whole platform body, the adjustment of position, all around, guarantees the installation accuracy of electric power facility.
Referring to Fig. 2, the parts that level(l)ing device relates to mainly contain substrate 230, lower plate 240, middle plate 220 and horizontal adjustment screw rod 501, horizontal adjustment screw rod 501 front ends are step-like, screw sleeve 231 on 230 4 angles of substrate is installed a horizontal adjustment screw rod 501 that has handle 50 respectively, described horizontal adjustment screw rod 501 steps can be crossed screw sleeve 231 by a direct rotary with the horizontal adjustment screw rod end 502 on top, substrate through-hole 232, lower plate through hole 241, the stroke groove 2211 of U-shaped plate 221, be positioned at stroke groove 2211 tops by alignment pin 503 then, because through hole 241 apertures of lower plate 240 less than through hole 232 apertures of substrate 230, cause the step of horizontal adjustment screw rod 501 bodies of rod to withstand on the bottom of lower plate 240.During adjusting, when turn levelling control lever 50 makes horizontal adjustment screw rod 501 up, it is up that the step of horizontal adjustment screw rod 501 just heads on lower plate 240, reaches the horizontal purpose of adjusting.
The parts that the front and back adjusting device relates to mainly contain lower plate 240, middle plate 220, front and back adjusting screw(rod), front and back adjusting screw(rod) one end and front and back regulating handle 10 link, and the screw rod cover through hole (the screw rod cover is positioned on the fixing hole 223) during the other end revolves on the plate 220, following crab bolt 242, end arrive front and back adjusting screw(rod) end cover 224.When front and back regulating handle 10 rotated, because crab bolt 242 is in stationary state down, plate 220 moved with top during the front and back adjusting screw(rod) just drove, the ultimate range that the stroke groove 2211 on the U-shaped plate 221 is regulated before and after being exactly.
The parts that the left and right adjusting device relates to mainly contain middle plate 220, upper plate 210 and left and right adjusting screw rod 301, the left and right adjusting screw rod 301 that connects with left and right adjusting handle 30, after passing the positioning sleeve 304 that is fixed on the right plate fixing hole 2112a, crab bolt 302, end arrived the screw rod cover 303 interior (both connect for movable) in left side in revolving.When rotating left and right adjusting handle 30, when left and right adjusting screw rod 301 moves, owing on the front side board 211 at front and back regulating handle 10 places, have stroke groove 211a, make upper plate 210 can make move left and right by middle relatively plate 220 with top, the width of stroke groove 211a is exactly the ultimate range of left and right adjusting.
