Embodiment
To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, with reference to
Embodiment, is expanded on further the present invention.
As shown in figures 1 to 6, can draw the vehicular guardrail drilling machine of drilling cramp in includes vehicle body 1, drilling cramp 3 and drilling rod assembly 4, vehicle body
1 lower end is provided with walking mechanism, and the front end of vehicle body 1, which is provided with driver's cabin 2, driver's cabin 2, is provided with hydraulic control mechanism, the hydraulic control
Mechanism is mainly that a multichannel manipulates valve.The drilling rod assembly 4 is liftably arranged on the drilling cramp 3, in addition to one is arranged on
Gathering mechanism 5 on vehicle body 1, for the drilling cramp 3 positioned at the outside of vehicle body 1 to be collapsed to the top of vehicle body 1.
The gathering mechanism 5 include a pedestal 51, be arranged on vehicle body 1 be used for drive the pedestal 51 in the horizontal plane
Rotating seat 53 that one end of the rotating mechanism 52 of swing, lower end and the pedestal 51 is hinged and for making the rotating seat 53 perpendicular
The first dump ram 54 swung in straight plane, the other end of the two ends of first dump ram 54 respectively with the pedestal 51
And the upper end of the rotating seat 53 is hinged.Integrated hydraulic fuel tank 6, and the preferably integrated form liquid are installed on vehicle body 1
Case 6 is pressed oil to be located on opposite side relative with the drilling cramp 3 on vehicle body 1.The integrated hydraulic fuel tank 6 includes fuel tank, set
Oil pump, filter, radiator on the fuel tank etc., each oil cylinder on vehicular guardrail drilling machine are integrated with this by oil pipe
Formula hydraulic oil container 6 is connected.
The vehicular guardrail drilling machine of the present invention, operationally, as Figure 1-3, drilling cramp 3 is located at outside the side of vehicle body 1, passes through
Drilling operation is realized in control drilling rod 4 lifting on drilling cramp 3 of assembly.In off working state, as Figure 4-Figure 6, drilling cramp 3 was before this
The position realized by the position of general vertical is rocked to the angle of horizontal plane is 25 ° or so is shunk by the first dump ram 54
Put, then again collapsed to the drilling cramp 3 in heeling condition directly over vehicle body 1 by rotating mechanism 52.In the present invention, first
Dump ram 54 can also adjust the degree that tilts of drilling cramp 3, to ensure borehole perpendicularity in addition to for drawing drilling cramp 3 in.
The vehicular guardrail drilling machine of the present invention, because drilling cramp 3 can be collapsed to directly over vehicle body 1, therefore drilling cramp 3 will not driving to driver
Sail the visual field to impact, while the aesthetics of complete machine is greatly increased.In addition, the whole height of drilling cramp 3 can be designed to it is higher, from
And range of the drilling rod assembly 4 on drilling cramp 3 is bigger, and then the drilling depth of drilling rod assembly 4 is deeper, specifically, of the invention
The drilling depth of vehicular guardrail drilling machine can reach 1700mm.
Due to drilling cramp 3 is collapsed into the top of vehicle body 1 by the outside of vehicle body 1, the angle that drilling cramp 3 is swung in the horizontal plane is only needed
90 °, therefore, the rotating mechanism 52 can be mounted in the rotary oil cylinder on vehicle body 1, however pedestal 51, drilling cramp 3 and
The grade of drilling rod assembly 4 can cause very big moment of flexure to the piston rod of rotary oil cylinder, the piston rod of rotary oil cylinder easily bend and
Scrap, therefore the reliability of rotary oil cylinder is poor, service life is short.The rotating mechanism 52 of the present embodiment preferably another structure,
Specifically, the rotation that one end including the base being arranged on vehicle body 1, one end and the base is hinged moves frame and for driving
State rotation and move the rotary oil cylinder that frame is swung in the horizontal plane, rotation moves frame and is hinged by a bearing pin and base, base is fixed with vehicle body 1 to be connected
Connect, the pedestal 51 is arranged on the rotation and moved on frame, described one end of frame is moved at the two ends of the rotary oil cylinder with the rotation respectively
And the other end of the base is hinged.The rotating mechanism 52 of the structure, bearing pin is not susceptible to flexural deformation, more reasonable structure,
Reliably, service life is longer.
As the further improvement of such scheme, the pedestal 51 moves frame with the rotation and is slidably connected, the gathering mechanism 5
Also include connecting the pedestal 51 and rotation and move frame, traversing oil cylinder 58 for driving the pedestal 51 to move in the horizontal plane,
It is preferred that the two ends of the traversing oil cylinder 58 move frame with rotation respectively and pedestal 51 is hinged.By traversing oil cylinder 58, drilling cramp 3 can be adjusted
Spacing during work between vehicle body 1, so that the drilling scope of the vehicular guardrail drilling machine of the present invention is bigger.The present embodiment
In, the distance between center line and vehicle body 1 of drilling rod assembly 4 maximum can adjust 1069mm.
As the further improvement of such scheme, the drilling cramp 3 is slidably arranged on a lift arm 55, the lift arm 55
Be connected with the rotating seat 53, be provided with a lift cylinder 56 on the lift arm 55, the piston rod of the lift cylinder 56 with
The lower end connection of the drilling cramp 3.Set lift cylinder 56 to adjust the height of drilling cramp 3, drilling cramp 3 is adapted to roughly
Face, to ensure that drilling rod assembly 4 can reach maximum drilling depth all the time.
As the further improvement of such scheme, the lift arm 55 is rotated with the rotating seat 53 and is connected, the lifting
The two ends of the upper end of arm 55 and the upper end of the rotating seat 53 respectively with one second dump ram 57 are hinged, and described second tilts oil
Cylinder 57 is used to drive the lift arm 55 to rotate around it pivot, second dump ram 57 be hinged with rotating seat 53 one
A perpendicular of the center of rotation by lift arm 55 is deviateed at end, plane where the swinging track of the lift arm 55 with
Plane where the swinging track of the rotating seat 53 is vertical.In the present embodiment, the second dump ram 57 can make drilling cramp 3 with
Lift arm 55 is swung together, and during work, the scope that drilling cramp 3 can deviate perpendicular is -25 ° to 20 °.Second is set to tilt oil
Cylinder 57, it is therefore an objective to which adjust drilling cramp 3 tilts forward and back degree, further to improve borehole perpendicularity.
As the further improvement of such scheme, in addition to dust arrester 7, the dust arrester 7 includes pulse dust collector
71st, the air compressor 72 being connected with the pulse dust collector 71 and the air inlet by sweep-up pipe 73 and the pulse dust collector 71
The dust shield 74 of mouth connection, pulse dust collector 71 and air compressor 72 are all located at vehicle body 1 with the integrated hydraulic fuel tank 6
The same side.The dust shield 74 is arranged on the lower end of the drilling cramp 3, and the drilling rod assembly 4 includes drilling rod 41, and the drilling rod 41 is worn
Cross the dust shield 74.Dedusting is carried out using pulse dust collector 71, good dedusting effect solves conventional rig using water dedusting
The problem of uninterrupted working time brought is short and influences construction speed.
As the further improvement of such scheme, the dust arrester 7 also includes the whirlwind for being arranged on the lower end of drilling cramp 3
Deduster 75, the cyclone dust collectors 75 connect the pulse dust collector 71 with the dust shield 74.What dust shield 74 was sucked
Dust carried out first time dedusting by cyclone dust collectors 75 before this, and most dust is discharged from the dust-exhausting port of cyclone dust collectors 75
And ground is fallen to, the dust of remaining fraction is removed by pulse dust collector 71 again.Removed using pulse dust collector 71 and whirlwind
Dirt device 75 is used cooperatively, and dust removing effects more preferably, while decreasing pulse dust collector 71 except dust quantity, extend pulse dust collector 71
Working life.
