During handle 23, hydraulic control proportional multi-way valve 21 is controlled by logic shuttle valve 20, now pilot operated directional control valve 18,19 hydraulic control ends are high pressure, liquid
Control reversal valve 18,19 works in left position, realizes the operation of hydraulic wireline winch.
The application method of truck-mounted drilling rig combined type lifting device is as follows in the present invention：
It includes going down process, drilling process and trip-out process, and in going down process, only oil cylinder hoisting mechanism works, and two
Level feed unit 10 is unloaded to be stretched out, and band, which carries, retracts.Detailed process is：Before stacks, drilling tool in the gripper hole of aperture, revolution
The connection screw thread with drilling rod is unclamped in the reversion of device 5, and feed oil cylinder 12 drives gyrator 5 unloaded up.Connect and newly add drill rod thread
Afterwards, aperture clamper unclamps, and the drill string weight in hole makes oil cylinder compression retraction, realizes the decentralization of drilling tool.
In drilling process, only oil cylinder hoisting mechanism works, and the unloaded motion upwards of gyrator 5, is then predominantly depressurized when downward
Drilling.From voltage endurance capability higher feed oil cylinder 12 and seal, it is high pressure resistant with seal so need to be only fed oil cylinder 12, and
Do not need pumping plant continuously to provide higher pressure, reduce energy expenditure, control the size of feed oil cylinder 12.
In trip-out process, when load is less than feed 12 maximum pulling capacity of oil cylinder, only oil cylinder hoisting mechanism drives revolution
Device 5 pulls out of hole.When load is more than oil cylinder maximum pulling capacity, it is not enough to lift drilling tool in hole.Now, gyrator 5 disengages lower day
Two of car 2, which rise, pulls out steel wire rope 8 and 2 feed steel wire ropes 11, is connected with hook block 4, is provided and pulled out by lifting of winch mechanism
Power.
As can be seen here, the upper overhead traveling crane 1 is connected with lower overhead traveling crane 2 by bearing pin, convenient dismounting.Needed for known target drilling
The maximum hoist capacity of truck-mounted drilling rig be less than feed 12 maximum hoist capacity of oil cylinder when, can not setting winch hoisting mechanism, both in rig
Before transport is in place, lifting of winch mechanism is pulled down, so as to reduce truck-mounted drilling rig transition and the deadweight in work progress, enhances brill
The mobility of machine, reduces energy consumption.
Upper overhead traveling crane 1 and hook block 4 on the oil cylinder winch combined type scheme apparatus for feeding is in long-distance transportation state
Under can be dismantled, reduce the main screw lift of truck-mounted drilling rig, improve Transport Safety.
Under conventional sense, on the basis of feed oil cylinder 12 voltage endurance capability is 32MPa, it is from voltage endurance capability
48MPa feed oil cylinder 12 makes support force bring up to 1.5 times, and pumping plant still only provides 32MPa pressure, the effectively save energy.
As seen through the above analysis, the compound mode of the oil cylinder winch is realized under two kinds of different working conditions
Operation, normal drilling and the when of falling bar, use oil cylinder hoisting mechanism, play its speed advantage；When handling drilling accident, pass through winch
The mode of hoisting mechanism assembly pulley reinforcement, there is provided ability is pulled out in bigger rising.Solve rig capability in handling accident and the effect that makes a trip
Rate is difficult to the problem taken into account, and significantly reduces additional energy loss and fuel consumption.
Existing truck-mounted drilling rig uses simple lay car hoisting mechanism or single cylinder hoisting mechanism, the precious high vehicle-mounted brill of RB50 types of Germany more
Machine is using winch and oil cylinder hoisting mechanism, but its mast length is fixed, and oil cylinder hoisting mechanism speed is slow, normal drilling and the when of falling bar
Operating efficiency is low, and present invention system implements the compound use with lifting of winch system in oil cylinder stretchable mast lifting system first.
Technique effect：
1. the present invention solve truck-mounted drilling rig construction deep hole should lifting force it is big, speed is fast again, and dimensional weight close
The problem of reason.It can realize that shallow bore hole accelerates construction speed with decompression drilling using oil cylinder speed lifting system currently without truck-mounted drilling rig
Spend and and can passes through lifting of winch system and exports bigger lifting force.
2. depressurizing in drilling process, larger drilling ability is can be achieved with by improving oil cylinder lifting system voltage endurance capability,
The problem of having avoided the pumping plant of the bigger ability of conventional use, cost, space are controlled, reduces energy expenditure.
3. first passage winch is compatible with oil cylinder lifting system, by being specifically defined making for oil cylinder and lifting of winch system
With method, the capability in handling accident of rig and the efficiency that makes a trip are taken into account, has been developed for truck-mounted drilling rig to big ability, high efficiency direction
Lay a good foundation.
In drilling process, the unloaded motion upwards of unit head, drilling is predominantly depressurized when downward, now banked direction control valves works in the right side
Position, rodless cavity connection overflow valve establish back pressure, prevent feed oil cylinder from retracting, and realize decompression drilling, drilling pressure passes through overflow valve
It is controlled.Only by increasing the voltage endurance capability of oil cylinder rodless cavity decompression need to be supplied to creep into bigger support force, without
Pumping plant continuously provides higher pressure, and cylinder structure and seal meet resistance to pressure request.Namely improve overflow valve and oil cylinder
Voltage endurance capability, you can realize rig decompression drilling ability raising.Lower pressure typically exists needed for truck-mounted drilling rig pressurization drilling
20tf or so, oil cylinder hoisting mechanism can meet.
The application method of the truck-mounted drilling rig combined type lifting device is specially：The oil cylinder hoisting mechanism is used to normally bore
Enter and rise and the operating mode such as pull out, need strength to rise to pull out and pulls out with exceeding oil cylinder after deep hole completion and rise when the lifting of winch mode is used for bit freezing
Operating mode is pulled out in rising for ability section.
It is readily apparent that the description and record of the above are only illustrated in the disclosure being not intended to be limiting of the invention
