Abstract
The invention relates to a rotary drilling rig for forming holes in a building pile foundation, in particular to a rotary drilling rig with an auxiliary supporting device. The rotary drilling rig with the auxiliary supporting device comprises a chassis and an upper vehicle arranged on the chassis. A big foldable arm is hinged to the upper vehicle and can vertically swing around the upper vehicle. A bracket is hinged to the front end of the big foldable arm. A drilling rod is installed on the bracket. A first hydraulic oil cylinder is further hinged to the bracket and is used for enabling the bracket to vertically rotate around the big foldable arm. Second hydraulic oil cylinders which are used for enabling the big foldable arm to swing are symmetrically arranged on the two sides of the big foldable arm. One end of each second hydraulic oil cylinder is hinged to the upper vehicle, and the other end of each second hydraulic oil cylinder is hinged to the big foldable arm. A supporting rod is further arranged at the bottom of the big foldable arm. One end of the supporting rod is hinged to the upper vehicle, and the other end of the supporting rod is hinged to the big foldable arm. By the adoption of the rotary drilling rig with the auxiliary supporting device, the height of the big arm and the height of the drilling rod can be reduced during transportation, a long drill bit can be installed, the auxiliary supporting function can be achieved on the big arm, and the safety of the rotary drilling rig is improved.
Description
Technical field
The present invention relates to the rotary drilling rig that a kind of building pile foundation pore-forming is used, be specially a kind of rotary drilling rig with auxiliary support apparatus.
Background technology
Rotary drilling rig is the construction machinery of pore-forming operation in a kind of building foundation engineering, in the multiple foundation basic constructions such as castinplace pile, diaphragm wall, underpin, is widely applied.Rotary drilling rig adjusts to adapt to the different operating modes such as transportation and construction to drilling rod angle by its guiding mechanism, the rotary drilling rig forming on the transformation basis of existing excavator structure is normally adjusted drilling rod by large arm and the hydraulic jack that is arranged on above large arm, the position of large arm front end can not be adjusted, in transportation, the position of drilling rod is higher like this, car load center of gravity is high, walking is inconvenience comparatively, also dangerous, and drilling rod below is highly lower, be unfavorable for installing long drill bit, can not bring into play the operating efficiency of machine.
goal of the invention
Object of the present invention is just to provide a kind of rotary drilling rig with auxiliary support apparatus, the height can reduce large arm and drilling rod transportation time, and longer drill bit can be installed, and can provide supplemental support effect to large arm simultaneously, improve the safety of rig.
To achieve these goals, technical scheme of the present invention is: a kind of rotary drilling rig with auxiliary support apparatus, comprise chassis and be arranged on getting on the bus on chassis, on described getting on the bus, be hinged with the folding large arm that can swing up and down around getting on the bus, the front end of folding large arm is hinged with bracket, drilling rod is installed on bracket, on bracket, be also hinged with the first hydraulic jack for bracket is rotated up and down around folding large arm, the bilateral symmetry of folding large arm is provided with the second hydraulic jack for making folding large arm swing, on one end of the second hydraulic jack is hinged on and gets on the bus, the other end is hinged on folding large arm, the bottom of folding large arm is also provided with support bar, on one end of support bar is hinged on and gets on the bus, the other end is hinged on folding large arm.
Described folding large arm is arranged on a side position of getting on the bus.
Described support bar comprises that sleeve and one end are installed in the expansion link in sleeve, the other end of expansion link is hinged with folding large arm, sleeve is hinged on gets on the bus, and expansion link and sleeve are provided with corresponding locating hole, is provided with the detachable alignment pin for locating expansion link in locating hole.
Beneficial effect: on the present invention is hinged on large arm to get on the bus, and in the bilateral symmetry of large arm, two hydraulic jacks are set large arm is supported and the adjustment of landing, can adjust by the landing of large arm like this height of drilling rod, hydraulic jack by large arm top is adjusted the angle of drilling rod, make the adjustment of drilling rod more flexible, and can reduce the height of large arm and drilling rod, rig is walked in transportation more steady, simultaneously in drill bit installation process, improve by the height that the adjustment of large arm landing is made to drilling rod bottom, be convenient to the installation of long drill bit, increase the length that drill bit is installed, increase the soil amount of putting forward.In the bottom of large arm, support bar being set further plays a supporting role to large arm, the height that support bar lifts according to the large arm adjustment of stretching, like this when the hydraulic system of rig breaks down while causing the second hydraulic jack not support large arm, can play a key role in supporting, prevent dangerous generation.
