Description
Technical field
The utility model relates to power shovel equipment, specially a kind of power shovel promotes weighing device.
Background technique
In present Production of Strip Mine, power shovel undertakes this and important task, on the haulage vehicle for completing ore shovel dress.Electricity
Shovel is mainly made of revolution, walking, promotion, racking systems.Big rack is mainly to support push part, provide fulcrum to promotion,
Tripod, which mainly passes through guy wire, makes big rack at one 45 degree, and an inspection is made to complete to promote and push two movements.
Ore is attached to mining self-discharging transporter by power shovel, and transport vehicle short distance within the scope of mining area is exercised back and forth, is reached broken
After broken machine, driver rises hydraulic hoist cylinder by operation handle, the compartment of scraper bowl type, and rear molding is opened wide without breast board, and compartment is lifted
30 degree are raised to, the ore in compartment unloads only, completes one-stop operation.
During geology, perforated blasting, cause the lumpiness of ore inconsistent, in loading process, driver can not be very
How many tons of ores are filled on the good every platform of control, few dress will cause inefficiency cost increase, and more dresses will cause overload of vehicle failure rate
Rise, cost equally rises, and needs a kind of weighing system at present, it is known that filled how many tons of cargos above every trolley, both may be used in this way
In the case where guaranteeing vehicle safety, conevying efficiency is improved, transportation cost is reduced, finds optimal key profit point.
At present to the weighing of mine truck cargo mainly by two kinds of forms:
The first mine truck fills ore by weighbridge, is measured by weighbridge, then notice dress ore power shovel
Driver, remind driver load a vehicle note that in process of production can not every trolley weigh, will cause low efficiency, make
It is all inconsistent at shovel dress yield, transport yield, broken yield.Simultaneously install weighbridge other than equipment cost, also need to do ground
Base hardening cost also needs human attendance.
Second of measurement method is to install pressure sensor on the ammonia cylinder of mine truck.Since the wagon box of mine truck is shovel
No rear backplate is opened in bucket type, tail portion, and ramp angle is 11 degree, and such ramp angle guarantee leaves to go up a slope in time, and ore can not be from vehicle
It is tumbled in bucket.The cartridge type hydro-pneumatic spring suspension that mine car uses, cylinder headspace carry out damping full of nitrogen.Wagon box 4 in total
Supporting point, before 2 supporting points contacts by damping block with bicycle beam support, 2 supporting points in back pass through nitrogen cylinder support.Pass through
Pressure measurement speculates ore weight.Because wagon box front is deep, tail portion is shallow, during filling ore, based on main first half, this
The value application condition that sample is measured is big, while having very high requirement to the flatness in the face of adopting, when vehicle leans forward or hypsokinesis
Cause the position of centre of gravity of vehicle different, the same application condition of the result of measurement is big.One well matched 3 fortune mine of power shovel in process of production
Vehicle, weighing system are installed on vehicle, if 3 times of the opposite power shovel of the number of units of installation, at high cost, maintenance complexity, while wagon box
The exhaust system of engine is also installed in bottom, easily causes exhaust system to go wrong during the installation process.
