The distance that object location detection device 8 detects stops lifting when being less than threshold value, to prevent pulleying, ensures the safety of lifting.
A specific embodiment is introduced with reference to Fig. 2 to Fig. 7.
Referring to Fig. 2 and Fig. 3, the drilling machine hoisting structure is by rotary reducer 10, lifting arm body, upper bracket 21, lower branch
Frame 22, cargo boom mounting bracket 23, hydraulic wireline winch 15 form.Lifting arm body includes revoliving arm 2, telescopic arm 3 and limiting device 4.It returns
Pivoted arm 2 is installed between the upper bracket 21 on outer layer boring tower 9 and lower bracket 22.Upper bracket 21 and lower bracket 22 are welded on outer layer
On boring tower 9.
Lifting arm body is mainly made of revoliving arm 2, telescopic arm 3, drive cylinder 33 and folding ram 40 etc..
Revoliving arm 2 is mainly used for installing telescopic arm 3, and drive cylinder 33 is flexible, coordinates with telescopic arm 3 and completes stretching for crane arm
Contracting.
Revoliving arm 2 is mainly used for realizing that the revolution of hoisting aids arm, 2 top of revoliving arm are installed rotary reducer 10, passed through
Motor above rotary reducer 10 drives revoliving arm 2, to realize the revolution of revoliving arm 2.
Join Fig. 2 to Fig. 4, the expanding-contracting action of the crane arm mainly passes through the flexible realization of drive cylinder 33, drive cylinder 33
Cylinder barrel end is connect with the otic placode of revoliving arm 2, and tailpiece of the piston rod is connect with telescopic arm 3 using axis pin.Telescopic arm 3 is assembled to revoliving arm 2
Inside rectangular tube, in order to reduce friction between telescopic arm 3 and revoliving arm 2, it is mounted with first respectively in 2 upper and lower both sides of revoliving arm
Sliding block 25 is mounted with the second sliding block 26 at left and right sides of it, ensures ride comfort when crane arm is flexible and uniform force.Driving
The cylinder barrel end of oil cylinder 33 is connected on the otic placode at 2 rear portion of revoliving arm, and tailpiece of the piston rod is connected on the rectangular tube on telescopic arm 3, is driven
The dynamic design of oil cylinder 33, in the case where ensureing to stretch stroke, reduces drive cylinder 33 inside the rectangular tube of telescopic arm 3
Mounting distance.The expanding-contracting action of crane arm increases lifting range, realizes the lifting of distant location drilling tool.
Join Fig. 2 to Fig. 4, the adjustment action of the crane arm pitch angle is mainly realized by folding ram 40, folding oil
Cylinder 40 is integrally formed three-legged structure with revoliving arm 2, telescopic arm 3 so that hoisting structure stress is more stablized.The folding ram 40 by
Two different oil cylinders realize the effect of two-stage hydraulic cylinder by the connection of structural member.The cylinder barrel end of the folding ram 40 and revolution
Connecting plate connection on arm 2, tailpiece of the piston rod are connect with the otic placode of 2 upper end of revoliving arm.When the folding ram 40 acts, due to two kinds
First oil cylinder 41 is different with the sectional area size of the second oil cylinder 42 so that cylinder action has sequencing.If it is extending action,
The angle that adjustment crane arm is first stretched out by the second larger oil cylinder 42 of sectional area, after fully extended, the first small oil cylinder of sectional area
41 start extending action.Working condition is reached if it is from travel position, then the sequencing of cylinder action is opposite.When transport,
First oil cylinder 41, the second oil cylinder 42 are fully extended so that crane arm is consistent with 9 direction of boring tower, and crane arm falls on lifting fupport arm
On frame 23, avoid leading to vehicle superelevation because hoisting arm structure is long.
The back rotation of the crane arm is made mainly to drive revoliving arm 2 to realize by rotary reducer 10, the upper end of revoliving arm 2 with return
Turn speed reducer 10 to connect with the revoliving arm 2 of lifting arm body by flat key, rotary reducer 10 by bolt and upper bracket 21 into
Row is fixedly connected；The lower end of lifting arm body passes through bearing and 22 assembly connection of lower bracket.Motor band on rotary reducer 10
Dynamic entire crane arm realizes rotary motion.
In addition, being based on security consideration, safety detecting system is devised on crane arm, ensures crane arm job safety.Tool
Body testing principle is：
(1), 2 rotation angle of revoliving arm is detected in crane arm rotary course, and corresponding detection signal is fed back to control
Device 200, controller 200 control the power head 20 of drilling machine.When crane arm has rotated on the motion path of power head 20, detection
To the angle of the rotation position, controller 200 controls power head 20, ensures 20 stop motion of power head, until crane arm is shown
The motion path of power head 20, controller 200 control power head 20 and can move.In 9 top of supply line of boring tower when crane arm operation,
Observation is inconvenient, is considered based on safety operation, the setting angle detection sensor on crane arm revoliving arm 2, prevent crane arm with
Power head 20 collides.Displacement sensor is installed on revoliving arm 2, detecting the retracted position of crane arm prevents overload from lifting by crane.
(2), the pitch angle detection of telescopic arm 3.The difference of crane arm pitch angle directly affects the lifting energy of crane arm
Power, therefore it is very necessary to carry out the detection of crane arm pitch angle.Pitch angle detection is carried out close to switch using angle,
The angle signal of detection feeds back to controller 200, and controller 200 controls the stroke of pitching oil cylinder.Different pitch angles rises
Weighing arm corresponds to different crane capacities.
(3), the flexible stroke detection of telescopic arm 3.The different stroke of crane arm also influences the crane capacity of crane arm, because
This must detect the flexible situation of crane arm.In 2 front end of revoliving arm of crane arm, limit switch is installed, installs and hangs on telescopic arm 3
Arm stretches detection plate, and when telescopic arm 3 is flexible, hoisting arm expansion detection plate triggers limit switch work, to detect that crane arm is
No stretching according to different stretching states and then is controlled the different crane capacity of crane arm, prevents from being lifted by crane due to overload, causing can
The safety accident of energy.
(4), the overwinding-proof detection on hydraulic wireline winch.Since hoisting structure is mounted on the upper end of boring tower 9, when constructing operation very
It is easy carelessness the distance between hoisting heavy and crane arm, it is more than safe distance that may lead to boom hoist weight, plays lift heavy
Object hits crane arm, causes that weight falls or steel wire rope 11 is pulled off.Therefore installation overwinding-proof distance detection, in telescopic arm 3
Front end install a weight limit sensors, detect weight and telescopic arm 3 safe distance, when weight touch weight limit
When the lower end weight 81 of sensor, detection signal is fed back to controller 200, controller 200 controls the motor of hydraulic wireline winch 15
It is stopped, avoids, due to carelessness, causing hoisting heavy to collide with hoisting arm structure part so that the operation of crane arm is more
Safety, more hommization.
The hoisting structure that above-mentioned technical proposal provides is suitable for vehicle-mounted/trailer-rig, is folding, when transport
