The utility model content
When being to solve the dismounting of prior art cooling tower special tower machine, the purpose of this utility model only uses the winch of self, wire rope handling, the rope that falls back and forth, cumbersome also very unsafe defect, provide a kind of two winchs that utilize, safe, as fast to dismantle counterweight and crane arm cooling tower special tower machine.
The utility model is achieved by the following technical solution:
it is a kind of cooling tower special tower machine, comprise tower body, crane arm and equilibrium arm, main winch and clump weight are installed on equilibrium arm, the ground that it is characterized in that tower body bottom one side is provided with auxiliary winch, equilibrium arm is provided with dismounting counterweight support, described tower body bottom, on the tower cap, be respectively equipped with first on support, second, the 3rd pulley, the steel rope of auxiliary winch is walked around above-mentioned 3 pulleys successively, be connected with clump weight, described crane arm is provided with the dismounting arm and saves support, the dismounting arm is saved support and is provided with the 4th pulley, the steel rope of described main winch is walked around the 4th pulley and is connected with crane arm.
As a preferred version of the present utility model: the first pulley is fixed on the tower body coxopodite.
Use the step of the utility model dismounting counterweight and crane arm as follows:
1, before tower machine dismounting, the auxiliary winch of 2 tonnages is fixed on ground in cooling tower;
2,22 tons of pulleys (the first pulley and the second pulley) are respectively fixed to tower body coxopodite (the upper first segment of rood beam) and tower cap place;
3, will assist the steel rope of winch to wear around the first pulley, the second pulley, then the dismounting counterweight to equilibrium arm is used in the 3rd pulley of support;
4, the steel rope that will assist winch is through in the counterweight hanger, and with steel rope with 3 12 #Buckle, chucking becomes rope sling, and card is 13 in rope sling #Shackle is connected with the counterweight hanger;
5, start auxiliary winch and rise, make counterweight leave soon counterweight attachment point 5-10cm and stop rising, bearing pin is extracted out;
6, start again auxiliary winch and descend, until clump weight is put into ground.
7, the crane arm of tower machine is dismantled along with the minimizing of clump weight, prevents from unloading process occurring safety misadventure.
8, will dismantle arm and save on the rear joint that support is fixed on the arm joint that will dismantle, and with the arm that the steel rope of main winch will be dismantled, save and fix;
9, after starting main winch and rising and to make the arm that will dismantle save into the angle of 20-35 degree, main winch quits work, and removes and connects bearing pin;
10, start general who has surrendered's arm joint under main winch and be put into ground;
11, by above-mentioned same steps as dismounting arm joint and clump weight until reach necessary requirement, namely crane arm just can be by the minimum diameter of cooling tower.
The utlity model has easy to operate, safety, advantage that efficiency is high.Main winch of the present utility model only is used for dismantling crane arm, and auxiliary winch only is used for dismantling clump weight, and Each performs its own functions for two winchs, need not back and forth wire rope handling, falls rope, and is easy and simple to handle, efficiency is high, safety performance is high.
