Description
Technical field
The present invention relates to a kind of rig, the rectangular opening rig that particularly pore-creating of a kind of underground concrete castinplace pile is used.
Background technology
At present, the rig that cast-in-place concrete pile is used is to be all drilled to a circular hole.
Summary of the invention
The present invention has made up above shortcoming, and a kind of rectangular opening rig is provided.
The present invention is achieved through the following technical solutions:
A kind of rectangular opening rig, drilling rod lower end is connected with fan-shaped framework, in fan-shaped framework, be provided with hydraulic drive cylinder, the hinged fan-shaped framework bottom, lower end of hydraulic drive cylinder, hinged the first lever in hydraulic drive cylinder upper end and the second lever lower end, hinged the first swing arm right-hand member in the first lever upper end, hinged the second swing arm left end in the second lever upper end, the centre of the top chain link of the first hinged left side of swing arm left end hinge, the hinged fan-shaped framework of the first swing arm medium position, the centre of the top chain link of the second hinged the right of swing arm right-hand member hinge, the second swing arm medium position is hinged fan-shaped framework also; Two hinges of the right and left form by several sections of chain links, and in the middle of every pitch chain joint, respectively by a hinged fan-shaped framework of pivoted arm, every pitch chain joint bottom is equipped with several cutter.
The present invention has following beneficial effect:
Hydraulic drive cylinder of the present invention drives two hinges in left and right to move reciprocatingly along circular arc, and the cutter on hinge bores at the volley and scrapes out rectangular opening.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated;
Fig. 1 is structural representation of the present invention;
In figure: 1, drilling rod, 2, fan-shaped framework, 3, hydraulically extensible device, the 4, first lever, the 5, second lever, the 6, first swing arm, the 7, second swing arm, 8, hinge, 9, pivoted arm, 10, chain link, 11, cutter.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention, this embodiment drilling rod 1 lower end is connected with fan-shaped framework 2, in fan-shaped framework, be provided with hydraulic drive cylinder 3, the hinged fan-shaped framework bottom, lower end of hydraulic drive cylinder, hinged the first lever 4 in hydraulic drive cylinder upper end and the second lever 5 lower ends, hinged the first swing arm 6 right-hand members in the first lever upper end, hinged the second swing arm 7 left ends in the second lever upper end, the centre of the top chain link 10 of the first hinged left side of swing arm left end hinge, the hinged fan-shaped framework of the first swing arm medium position, the centre of the top chain link of the second hinged the right of swing arm right-hand member hinge, the second swing arm medium position is hinged fan-shaped framework also, two hinges of the right and left form by several sections of chain links, and in the middle of every pitch chain joint, respectively by a hinged fan-shaped framework of pivoted arm 9, every pitch chain joint bottom is equipped with several cutter 11.
When the present invention works, hydraulic drive cylinder always regular one is stretched a contracting campaign, drives thus two hinges in left and right to move reciprocatingly along circular arc, and the cutter on hinge bores at the volley and scrapes out rectangular opening.
