Abstract

The utility model relates to a rotary drilling rig, which relates to building pile foundation pore-forming equipment. The rotary drilling rig comprises a chassis and an upper car arranged on the chassis, wherein a big foldable arm capable of swinging up and down around the upper car is hinged to the upper car; a bracket is hinged to the front end of the big foldable arm; a drill rod is arranged on the bracket; a first hydraulic cylinder for enabling the bracket to rotate up and down around the big foldable arm is also hinged to the bracket; second hydraulic cylinders for enabling the big foldable arm to swing are symmetrically arranged on two sides of the big foldable arm; one end of each second hydraulic cylinder is hinged onto the upper car, and the other end of each hydraulic cylinder is hinged onto the big foldable arm. According to the rotary drilling rig, the height when the big arm and the drill rod are transported can be reduced, the drilling rig can be walked stably during a transportation process, the length of an installation drill can be increased, the soil lifting amount is increased, the working times for the round trip of the drill rod are reduced, and the working efficiency is greatly improved.

Description

A kind of rotary drilling rig
Technical field
The utility model relates to a kind of building pile foundation pore-forming equipment, is specially a kind of rotary drilling rig.
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.
utility model content
The purpose of this utility model is just to provide a kind of rotary drilling rig, the height in the time of can reducing large arm and drilling rod transportation, and can install compared with long drill bit and improve each soil amount of putting forward, bring into play the optimum performance of machine.
To achieve these goals, the technical solution of the utility model is: a kind of rotary drilling rig, 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 for making the second hydraulic jack of folding large arm swing, one end of the second hydraulic jack is hinged on gets on the bus, and the other end is hinged on folding large arm.
Described folding large arm is arranged on a side position of getting on the bus.
Beneficial effect: on the utility model 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 to the adjustment with landing, can adjust by the landing of large arm the height of drilling rod like this, 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, by the height of drilling rod bottom being improved to the adjustment of large arm landing, be convenient to the installation of long drill bit, increase the length that drill bit is installed, increase the soil amount of putting forward, reduce drilling rod and come and gone work times, greatly improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, be labeled as: 1, chassis, 2, get on the bus, 3, folding large arm, 4, bracket, 5, drilling rod, the 6, first hydraulic jack, the 7, second hydraulic jack.
The specific embodiment
As shown in Figure 1, a kind of rotary drilling rig, comprise chassis 1 and be arranged on and the One On The Chassisly get on the bus 2, describedly get on the bus that be hinged with on 2 can be around the 2 folding large arms 3 that swing up and down of getting on the bus, the front end of folding large arm 3 is hinged with bracket 4, drilling rod 5 is installed on bracket 4, on bracket 4, be also hinged with the first hydraulic jack 6 for bracket 4 is rotated up and down around folding large arm 3, the bilateral symmetry of folding large arm 3 is provided with the second hydraulic jack 7 for folding large arm 3 is swung, one end of the second hydraulic jack 7 is hinged on gets on the bus on 2, and the other end is hinged on folding large arm 3.Described folding large arm 3 is arranged on 2 the side position of getting on the bus, and 2 the opposite side of getting on the bus is driver's cabin.The first hydraulic jack 6 is all connected with the hydraulic system of rotary drilling rig with the second hydraulic jack 7.
