Abstract

The invention discloses a ramp replacement mode for electric shovel excavation. The ramp replacement mode comprises the following steps that 1, before an electric shovel starts excavation, a first connecting ramp is laid in a direction opposite to the excavation direction; 2, the electric shovel performs excavation propulsion in the excavation direction, and a transport vehicle completes shovel inlet and shovel outlet actions through the first connecting ramp; when the electric shovel is forwards propelled, and the distance between the shovel position and the first connecting ramp is increased, a second connecting ramp is arranged in a direction opposite to the excavation direction of the electric shovel; 4, after the second connecting ramp has the passing conditions, the first connecting ramp is disused, and the transport vehicle performs shovel inlet and shovel outlet operations through the second connecting ramp; and 5, the steps are repeated, so that the connecting ramps are arranged in a synchronous forward propulsion manner along with the electric shovel excavation. The ramp replacement mode for electric shovel excavation has the advantages that the transportation distance of an open pit truck can be reduced; the open-air production efficiency is improved; and the production cost is reduced.

Description

The ramp substitute mode of power shovel digging
Technical field
The present invention relates to opencut power shovel digging field, particularly to the ramp displacement side of a kind of power shovel digging Formula.
Background technology
China's opencut opencut all uses shiftable ramp to open up means of transportation, existing open pit development at present Transport ramp be arranged in more from stope position farther out end side, power shovel stope position often has with channel location One segment distance, adds the transportation range arriving this section of contact ramp after truck goes out shovel, the opencut of reduction Production efficiency, adds Production of Strip Mine cost.
The information being disclosed in this background section is merely intended to increase the reason of the general background to the present invention Solve, and be not construed as recognizing or imply in any form that this information structure is for this area general technology Prior art well known to personnel.
Summary of the invention
It is an object of the invention to provide the ramp substitute mode of the power shovel digging of a kind of simple and reasonable steps, The ramp substitute mode of this power shovel digging can save outdoor anti-truck transport distance, improves outdoor production Efficiency, reduces production cost.
For achieving the above object, according to the invention provides the ramp substitute mode of a kind of power shovel digging, bag Including following steps: step one, before power shovel starts digging, rightabout in its digging direction lays Article 1 Contact ramp;Step 2, power shovel advances along the digging of digging direction, and Article 1 contact ramp walked by haulage vehicle Complete into shoveling out shovel action;Step 3, when power shovel is pushed ahead so that ramp is got in touch with Article 1 in shovel position Between distance when increasing, opposite direction in power shovel digging direction lays Article 2 contact ramp;Step 4, After Article 2 contact ramp possesses current condition, Article 1 being got in touch with ramp and stops using, haulage vehicle enters Shovel out shovel and walk Article 2 contact ramp;Step 5, repeat the above steps so that power shovel is followed in contact ramp The propelling of digging synchronizes to push ahead laying.
Preferably, in technique scheme, in step 3, the distance that power shovel is pushed ahead is 50-70 rice.
Preferably, in technique scheme, the distance that power shovel is pushed ahead is 60 meters.
Compared with prior art, there is advantages that the ramp displacement side of this power shovel digging Formula can save outdoor anti-truck transport distance, improves outdoor production efficiency, reduces production cost.
Accompanying drawing explanation
Fig. 1 is that the Article 1 contact ramp of the ramp substitute mode of the power shovel digging of the present invention forms schematic diagram.
Fig. 2 is that the Article 1 contact ramp of the ramp substitute mode of the power shovel digging of the present invention utilizes schematic diagram.
Fig. 3 is that the Article 2 contact ramp of the ramp substitute mode of the power shovel digging of the present invention forms schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described in detail, it is to be understood that this The protection domain of invention is not limited by detailed description of the invention.
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " bag Include " or its conversion as " comprising " or " including " etc. will be understood to comprise stated element or Ingredient, and do not get rid of other element or other ingredient.
The concrete steps of the ramp substitute mode of this power shovel digging include:
Step one, the rightabout that power shovel starts before digging in its digging direction lays Article 1 contact ramp 1;
As it is shown in figure 1, the distance of Article 1 contact ramp 1 and truck is L1.This distance L1It is according to dew The Article 1 that it ore deposit knowhow and physical device Size calculation go out gets in touch with the minimum range in ramp 1 and truck.
Step 2, power shovel advances along the digging of digging direction, and haulage vehicle is walked Article 1 contact ramp 1 and completed Enter to shovel out shovel action (as shown in Figure 2).
Step 3, when power shovel is pushed ahead so that the distance between shovel position and Article 1 contact ramp 1 increases Added-time, the opposite direction in power shovel digging direction lays Article 2 contact ramp 2;
As it is shown on figure 3, the distance that power shovel is pushed ahead is 50-70 rice, Article 2 contact ramp 2 and card The distance of car is L2
Step 4, after Article 2 contact ramp 2 possesses current condition, gets in touch with Article 1 ramp 1 and stops Using, haulage vehicle enters to shovel out shovel and walks Article 2 contact ramp 2 (as shown in Figure 3);
Step 5, repeat the above steps so that contact ramp is followed the propelling of power shovel digging and synchronized to push away forward Enter to lay.
To sum up, the ramp substitute mode of this power shovel digging can save outdoor anti-truck transport distance, improves Outdoor production efficiency, reduces production cost.
The aforementioned description to the specific illustrative embodiment of the present invention illustrates that and the purpose of illustration. These descriptions are not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned Teaching, can much change and change.The purpose selected exemplary embodiment and describe exists In explaining the certain principles of the present invention and actual application thereof, so that those skilled in the art can be real Now and utilize the various different exemplary of the present invention and various different selection and change. The scope of the present invention is intended to be limited by claims and equivalents thereof.
