Embodiment Construction

[0022] The overall lifting method of the bulldozer provided by the embodiment of the present invention includes conducting a feasibility test before the whole bulldozer lift, so as to determine the climbing ability of the bulldozer and the unloading truck, and then determine the walking speed of the bulldozer based on this. The road construction plan and the determination of the construction plan for the unloading vehicle to walk the railway, and finally the construction plan for the lifting section of the earth dumper.

[0023] A. to conduct a feasibility test

[0024] The test environment is determined according to the mine conditions: the iron ore dump site of Shougang Waterworks has a temperature of -25°C to +40°C, an annual average rainfall of 756mm, a daily maximum of 283mm, a maximum wind speed of 16.7m / s, and a maximum snowfall of 16cm. The rock composition is mixed with marble, gneiss, feldspar and quartz stone, the original rock density is 2.71t / m3, the soft rock den...

Abstract

The invention discloses a whole ascending method of a dumping machine. The whole ascending method of the dumping machine comprises the following steps: carrying out a feasibility test before the dumping machine entirely ascends, so that the climbing abilities of the dumping machine and a dummy car is to determined; determining the width and the slope angle of a walking road of the dumping machine, the minimal bearing capacity of the pavement, heights of soil baffles at two sides of the road, a distance value of a creeper tread of the dumping machine and a side slope according to the climbing abilities of the dumping machine and the dummy car; and determining the length, the gradient, the track gauge, the offset curve radius, the distance of a light sleeper, the maximal permitted error of the track gauge, the maximal variable quantity of a walking railway of the dummy car, and the transverse inclination angle of a railway and the side slope of the end face distance of the light sleeper of the track. According to the whole ascending method of the dumping machine provided by the invention, an entire driving mode is adopted; the dumping machine is lifted to a dumping stage height, and the technical problems of driving and ascending of the dumping machine under the conditions of a heavy grade, a small turning radius, a long-distance continuous climbing and non-dismantling are solved under the situation that a dumping device such as a large dumping machine at present has no existing technical scheme to refer to are solved.

Description

technical field [0001] The invention relates to the technical field of belt-transported earth-discharging technology for large-scale open-pit mines, in particular to a method for integral lifting of earth-moving machines. Background technique [0002] In May 2011, the dumper at the Shougang Waterworks Iron Mine Hexi dump site completed the 220m horizontal dumping operation, and needed to raise the dump site from the 220m level to the 265m level. The soil dumpers used in the Hexi and Hedong dump sites of Shougang Waterworks Iron Mine are manufactured by voestalpine and Dalian Heavy Industry. The total length of the equipment is 142.35m, the width is 15m, the height is 25.19m, and the total weight is 700t. [0003] According to the upgrading plan provided by the experts of VAI, the lifting section needs to disengage the receiving arm of the dumper from the unloading truck, hang the disengaged receiving arm on the counterweight frame of the dumper, and place the original counte...
