Detailed Description
As can be seen from fig. 1 to 3, the dual-purpose raise boring machine chassis disclosed in the present embodiment includes a structural frame 1, a rail wheel 2 and a vertical machine support 3.
The structural frame 1 comprises longitudinal beams 11 on two sides and connecting members between the longitudinal beams, the bottom surfaces of the head section and the tail section of each longitudinal beam are higher than the bottom surface of the middle section, and the bottom surface of the middle section is a horizontal plane.
The head section of the longitudinal beam 11 is provided with a 7-shaped notch which is concave upwards, and the tail section comprises an upper inclined section and a horizontal section behind the upper inclined section.
The rail wheels 2 are provided with a front pair and a rear pair and are respectively arranged on the inner side of the head section of the longitudinal beam 11 corresponding to the 7-shaped notch and the inner side of the horizontal section of the tail section, so that the lowest position of the rail wheels is higher than the lowest surface of the longitudinal beam.
The head sections of the two longitudinal beams 11 are symmetrically hinged to the vertical machine support 3 corresponding to the 7-shaped gap, and the longitudinal beams 11 can rotate around the hinged positions of the longitudinal beams and the vertical machine support 3.
The machine standing support 3 comprises a supporting main body, wherein the outer side of the top of the supporting main body upwards extends out of a hinged lug plate, and a supporting shoe plate is arranged at the bottom of the supporting main body.
When a steel rail is laid on a construction site, the base plate moves on the steel rail through the two pairs of rail wheels 2, and the longitudinal beam 11 of the structural frame is positioned on the outer side of the steel rail, so that the walking of the base plate along the steel rail is not influenced, and the vertical machine positioning of the raise boring machine is facilitated.
When no steel rail is laid on a construction site, the bottom surface of the middle section of the longitudinal beam 11 of the structural frame is lower than the lower edge of the rail wheel 2, and the chassis can stably fall on the foundation base plane through the longitudinal beams at two sides, so that the raise boring machine can smoothly stand.
Namely, the head part and the tail part of the chassis structure frame are respectively embedded with the pair of rail wheels 2, so that the chassis can be simultaneously suitable for foundation foundations with and without steel rails, and the adaptability of the working environment is improved.
In order to ensure the stability of the raise boring machine during the erecting, the head parts of the longitudinal beams 11 on the two sides of the structural frame are symmetrically hinged with the erecting support 3.
When the raise boring machine of the raise boring machine is erected on the chassis, the supporting shoe plate of the erecting support 3 is supported on the foundation, and the longitudinal beam of the structural frame rotates upwards around the hinged position of the longitudinal beam and the erecting support, as shown in figure 3. Under two different working conditions, the height difference of the supporting shoe plate required to be adjusted after the machine is erected is very small, and the stability of the machine erecting work of the raise boring machine is fully ensured.
The chassis can be additionally provided with the rail wheel and the vertical machine support under the premise of not changing the structural size of the chassis structural frame of the traditional drilling machine, so that the chassis can be exchanged with the chassis of the traditional raise boring machine, the environmental adaptability of the traditional raise boring machine is improved, the foundation with the steel rail can be used, and the foundation without the steel rail can also be adapted. The chassis of the traditional raise boring machine can be transformed, and the transformation cost is low.
