Problems solved by technology
Due to the small adjustable range of the leaf spring support, the drilling rig is greatly affected by terrain factors
When the vehicle is running on a road with bad road conditions, it will cause the whole machine to bump up and down, left and right, which will seriously affect the steering performance of the whole machine and the driving stability of the whole machine
Once the vehicle is super high and passes through the height-limited bridge hole, the height of the vehicle cannot be adjusted, causing the vehicle to fail to pass, which seriously restricts the passing performance of the vehicle-mounted drilling rig and affects the popularization and application of the vehicle-mounted drilling rig.
During the short-distance transition process, the vehicle will carry many parts randomly and directly transition, and the leaf spring support has a large weight limit on the vehicle

Embodiment Construction
[0027] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0028] In the present invention, a plurality of semi-active suspension oil cylinders are configured for the axle of the chassis of the drilling rig, and the semi-active suspension oil cylinders are used to connect the vehicle frame and the vehicle axle, and support the vehicle frame, and the semi-active suspension oil cylinders are provided There is a through valve, which can connect the semi-active suspension oil cylinder, and the through valve can also be controlled to open or close through external control, which makes the chassis of the drilling rig can be driven on the road according to the excitation of the road when the through valve is opened. In the case of semi-active suspension cylinders, the oil is automatically adjusted, and the piston rod of the suspension cylinder is driven to automatically extend and ret...

The invention relates to a chassis special for a drilling machine vehicle. The chassis comprises a frame and axles with more than two shafts, and the axles are sequentially arranged below the frame along the front-rear direction of the frame. The chassis is characterized by further comprising multiple left semi-active suspension oil cylinders and multiple right semi-active suspension oil cylinders which are matched with the axles in number, the left semi-active suspension oil cylinders and the right semi-active suspension oil cylinders are vertically arranged on the left side and the right side of the frame, mounted between the frame and the axles, used for connecting the frame with the axles and supporting the frame, and connected with communicating valves respectively, and the communicating valves are used for communicating the left semi-active suspension oil cylinders with the right semi-active suspension oil cylinders and can be opened or closed through an external control mode. By the chassis, the drilling machine vehicle is enabled to be suitable for severe working conditions, influences of topographic factors are reduced, and off-road capability is improved.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a special chassis for drilling rig vehicles. Background technique [0002] With the high-speed and rapid economic growth and the massive consumption of oil and natural gas resources, the future energy shortage is a major problem that all countries will face. At present, all countries are actively seeking new alternative energy sources. Recently, my country has successively issued policies to increase the exploration and exploitation of coalbed methane, oil shale and other unconventional new alternative energy sources. The new type of special vehicle-mounted drilling rig suitable for coalbed methane and oil shale mining is a sunrise industry in line with national industrial policies. [0003] Drilling rig is a kind of engineering vehicle driven by the power head, which meets certain drilling technology and can carry out drilling construction. This kind of engineering vehicle...
