Description
Technical Field
[0001] The utility model relates to the technical field of tunnel drilling machines, in particular to a multifunctional base of a tunnel drilling machine. Background Art
[0002] A tunnel boring rig is a piece of mechanical equipment used in tunnel engineering, which reduces the difficulty and workload of manual tunnel excavation. When a tunnel boring rig is in use, due to the instability of the working surface, the drilling rig needs a certain compensation distance when drilling. At the same time, when the ground is uneven, it is necessary to raise the ground to achieve verticality between the drilling rig and the working surface.
[0003] However, there are some shortcomings in tunnel drilling rigs at this stage. For example, the application number is 202323194869.8, which discloses "a feed compensation base for a tunnel drilling rig, including a base platform, a base, a crawler assembly, a slider, a telescopic cylinder, a base cylinder seat, a guide rail, a platform cylinder seat, a steel beam, a concave plate and a cover plate. The device of the utility model has a simple structure. When the telescopic cylinder is working, it can drive the base platform to move back and forth, which can well provide a compensation distance for the drilling rig when feeding. Compared with a drilling rig without a compensation seat, when crushed gravel is accumulated in front of the crawler, it can still work through stroke compensation, reducing the number of times the drilling rig is withdrawn to clear gravel during construction processes such as tunnel excavation, greatly facilitating the use of drilling equipment during construction, and helping to improve construction efficiency." It moves by cooperating with the guide rail and the slider, which is prone to deformation and replacement. In addition, the overall height of the drilling rig is not adjustable when in use. Since the drilling rig moves by the crawler, when there is gravel on the ground, the drilling rig cannot maintain a horizontal state, which will affect the operation of the drilling rig.
