20/5t, 35m clip-rail gantry cranes across the theoretical analysis and calculation devices


Eleven rail device 1 folder manually sketch map. 1 - handle; 2 a rack; 3 - Track l4 - clamp body l5 - pin 3 on both sides of the track to produce two equal and opposite, not a straight line on the two positive pressure P is, The two positive pressure will form a pair couple M = P is × 140ram, in order to balance the torque generated by the wind Ml = P wind X330ram. That relationship is; Pi × 140ram = P wind X330ram. While being under the influence of pressure P is, on both sides of the track and the crane moves in the opposite direction of the two friction f, the relation is f = P is XX2. Where:: 0.15 for the coefficient of friction, 2 for a single track on both sides, relying on friction f and a pair of couple's role to prevent the crane move.

(4) a (4) see chapter = o. 7o7, is a number less than 1,abercrombie paris, showing that f <P style is the original clip A few tracks device size is unreasonable, so that f <P style, so locking is not effective. Second, the playing track to improve the original folder manually locking device results will manually change its geometry to make the device Zhen tight crane rail clip, the wind must be f ≥ P, it is necessary to improve rail clip device unreasonable fL any size, and improving program There are three 1, increasing the arm length of the clamp body 4; 2, narrowing the width of the clamp body 4, 3, 4 to increase the arm length of the clamp off and reduce the width of the clamp body 4. These three improvements to the program, we calculated separately the following: 1, increasing the arm length of the clamp body 4 located clamp arm length of the body 4 Lmm, fL × P air = P is × 140, then P is P = Export Wind × 140,. *. L =- 466 friends. For ≥ 1, so the clamp body 4 of the arm length L of a minimum of 466.67mm. Arm length than the original increase 466.67-330:136.67 mm. Growth of the arm length, shell space beyond the clip track the extent permitted, so the program can not be accepted. 2, narrow the width of the clamp body 4 located clamp body 4 with a width of Bmm, / P is × B: 330 × P then P is the wind: blog export. B:: 99 pull out because of ≤ 1, so the clamp body 4 of the maximum width B = 99mm. The width of the clamp body width than the original reduction 140-99 = 41mm. Pliers to reduce the width of the body too much, clamp body strength will be reduced a lot: if the wind is too large, the risk of damage clamp body, so the program can not be used. 3, increasing the arm length of the clamp body 4 and narrow the width of the clamp body 4 of the program is to increase the arm length of the clamp body 4, but the shell space in the folder track within the allowed range, narrow the width of clamp body 4, but as far as possible the strength of the lower clamp body is not. The program on {1 One ..... . __ / 3 of the Act to ensure law chamfer jaw jaw width of the original B = 140mm, only to fall into the four corners of clamp rl 10 × 45. This makes the effective width of jaw 120mm, the use of the clamp body strength has little effect. Here the width of 120ram clamp body condition, calculated body clamp arm length. / L · P wind: P is 120 set: P is = to dismiss: LP style = to × 20, L = × .., Because ≥ l, so L ≥ 00mm, the length of the clip rail arm shell space within the allowable range. Calculated from the above that, when the jaws of the effective width of 120mm, the arm length of the clamp body is greater than or equal to 400mm, can lock tracks, folder tracks for the role play. Therefore, we calculate the theoretical analysis and based on track does not change the original folder / reasonable geometry, draw the map production process to produce a reasonable geometry of the new folder track device. The new folder using the rail device 20/5t,-35m gantry cranes at 19884F-cross put into use has been for four years after a few wind test, without any surprises. A 23 a
