Because all driver trains are that hoist winch, span winch of swing type mechanism, the main winch that hoists, pair adopts hydraulic-driven in the prior art; Cost an arm and a leg; Therefore hoist winch 14, span winch 15 of the above-mentioned swing type mechanism of all driver trains in the present embodiment 6, the main winch 16 that hoists, pair adopts the frequency control type of drive, reduced manufacturing cost.
During use, complete machine is connected with the cylindrical shell on the rock disintegration station is basic through butt flange 5, is about to lifting and is fixed on above the rock disintegration station.Main hook 30 hangs the rock breaker that the inside, rock disintegration station need hang out maintenance through heaving pile, and the main winch 16 that hoists starts, and coiling main hook steel rope 21 is realized main hook 30 dipping and heaving, will be sling by service parts.Span winch 15 starts, and coiling luffing steel rope 19 is realized the motion of pitching luffing thereby drive jib 2, will be adjusted to proper height by service parts.Swing type mechanism 6 begins action, and rotary column 1 is rotated, and will be forwarded to outside, rock disintegration station by service parts, and main hook 30 is put into ground, promptly unloads by service parts.
The structure of this hoisting crane has the following advantages:
1, changes the crane structure pattern, make the stressed mechanical model of jib change two power bars into, to alleviate jib weight by cantilever beam;
2, built-in range upon range of spatial destribution winch design: this hoisting crane requires the afterbody radius of turn less, in order to avoid interfere miscellaneous equipment on the rock disintegration station.This hoisting crane contains the main winch that hoists, span winch, the pair winch that hoists; Totally three winches, these three winches can not be arranged on the same rotating disk, and this hoisting crane is not established rotating disk; Three winches can only be arranged in rotary column inside; Be built-in range upon range of spatial destribution, be separately positioned on the inner three layers of platform of rotary column, hoisting crane afterbody radius of turn is reduced to minimum.
3, the last rotary column design of special structure form: this hoisting crane is a revolving crane, and last rotary column directly is connected with basic tower tube through three row's roller pivoting supports, realizes revolution.Last rotary column bottom is a cylindrical shell, and it is the round section structure, can make things convenient for basic tower to be connected.The middle part is two H-girders, between H-girder, is provided with surface plate and forms platform, master's winch, span winch, pair winch that hoists that hoists is located on the platform, and is provided with the frustum that cross-sectional plane is a rectangle between middle part and the bottom.The top is the box beam structure, and last rotary column version is unique, realizes the nature transition between the different cross section, and power transmission is clear, and is stressed clear and definite, designs unique characteristics.
4, built-in rotary motion mechanism design: it is inner that this crane rotation mechanism is placed on rotary column; It is inner that the miniature gears of swing type mechanism retarder end and the big internal gear on the pivoting support are engaged on rotary column; The bisque that produces when avoiding rock disintegration damages the flank of tooth, and this swing type mechanism is specially to the design of rock disintegration station working environment.
5, electronic full frequency conversion drive mode substitutes the full hydraulic drive mode: the master of this hoisting crane hoist winch, span winch, pair hoist winch, swing type mechanism, all adopt the frequency control type of drive, and realize safe and reliable, economical and energy saving, effect easy to maintenance.
6, special steel rope is worn around mode: the steel rope of major-minor hook, luffing is all through last rotary column top pulleys group; And then around arriving jib top pulleys group; When load hoists; Hoist rope has synergism to luffing, realizes littler luffing power, avoids the major-minor hoist rope to interfere other parts simultaneously.
