Accompanying drawing explanation
The structural representation of Fig. 1 embodiment of the present invention.
Detailed description of the invention
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
With reference to figure 1, the present invention relates to a kind of floor mast, comprise the pole main body be made up of standard knot 1, the bottom of described pole main body is provided with hoisting frame 2, both sides in described hoisting frame are respectively equipped with a jacking cylinder 3, the movable end of described jacking cylinder is other is provided with operating platform 4, the middle part of described pole main body is provided with pumping plant 5 and elevator joint 6, the upper end of described pole main body is provided with a bearing 7, described bearing is provided with pivoting support 8, described pivoting support is provided with rocker arm bracket 9, the both sides of described rocker arm bracket are provided with a rocking arm 10, the middle part of described rocker arm bracket is longitudinally provided with a mast 11, described mast top is provided with respectively around the home to the variable-amplitude steel wire rope 12 on rocking arm movable end, described rocking arm movable end also there is hoisting wirerope 13 around the home, described rocking arm comprises the rocking arm coxopodite 14 being articulated with rocker arm bracket, be connected to the rocking arm standard knot 15 on rocking arm coxopodite and be connected on rocking arm standard knot and the rocking arm cap 16 of hoisting wirerope around the home, both sides in the middle part of described mast are hinged with a rocking arm upper frame 17 and respectively and shore oil cylinder 18, the described movable end shoring oil cylinder is hinged on the middle part of respective side rocking arm upper frame.
The top of above-mentioned mast is provided with mast cap 19.
The movable end of above-mentioned hoisting wirerope is provided with suspension hook 20.
In implementation process:
Rocking arm specific implementation process is as follows:
When the two rocking arm of pole needs to put down, operation control assembly, luffing elevator is rotated, and variable-amplitude steel wire rope is sent, and cylinder rod is automatically released under the effect of pressure oil, and drives rocking arm upper frame to rotate, and push rocking arm and rotate, rocking arm just can put down; When rocking arm needs to regain; haul rocking arm by variable-amplitude steel wire rope and carry out receipts arm; cylinder rod is forced to be regained; because there is the damping action that the resistance of oil cylinder produces; rocking arm slowly can only be regained along with the withdrawal of variable amplitude rope; mast can not be clashed into because rocking arm regains fast and cause the accumulation of variable-amplitude steel wire rope, thus protects rocking arm and mast and ensure that luffing hoist engine arranges rope smoothly, ensureing pole work safety.
It is as follows that hoisting frame and oil cylinder etc. promote operation process:
1) each standard knot divides 3 jackings just can complete, and when oil cylinder pushes up at every turn and puts in place (holder iron lower plane is higher than plane 20mm on square cotter), put in place by 4 square cotter pins, then slowly put down by oil cylinder, after square cotter load-bearing, oil cylinder can comparatively fast return;
2) each jacking, lifting beam must withstand in holder iron reliably, during jacking 50mm, stops and observes, after all are normal, is return by 4 square cotters, continues jacking and puts in place, square cotter pinning;
3) circulation jacking like this 3 times, completes the jacking process of a joint standard knot;
4) then with crane, an other joint standard knot is put on dolly, adjust position, slowly shift onto in hoisting frame, with oil cylinder jack-up slightly, connect with the standard knot of top, dolly exits, and oil cylinder slowly puts down, until standard knot is placed on subplate bearer, if continuation jacking, jacking can be carried out by said sequence, if no longer jacking, standard knot should be fixed on subplate bearer.
5) jacking process should examine, and conscientiously operates, and after noting abnormalities and reporting to the police, stops immediately, can continue jacking after processing.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
