Abstract
The utility model relates to a counterweight telescoping mechanism for a rotary drilling rig, which comprises a rotary platform, a telescoping oil cylinder and a telescopic counterweight device, wherein both ends of the telescoping oil cylinder are respectively connected with the rotary platform and the telescopic counterweight device. A slideway is installed at the rear end of the rotary platform, and a clamping jaw which is placed in the telescopic counterweight device is connected together with the rotary platform. The counterweight telescoping mechanism for the rotary drilling rig has the beneficial effects that the matching problems of a multifunctional working device for the rotary drilling rig with a counterweight and the same working device with the counterweight under different amplitude-changing conditions are solved, so that the overall stability of the rotary drilling rig in a multifunctional state is ensured, and the weight of the drilling rig can be effectively reduced in a transporting state.
Description
Technical field
The utility model relates to a kind of rotary drilling rig, relates in particular to a kind of rotary drilling rig counterweight telescoping mechanism.

Summary of the invention
The utility model technical problem to be solved is: a kind of rotary drilling rig counterweight telescoping mechanism is provided, solves the equipment and the counterweight coupling of rotary drilling rig multifunction; And same equipment under different luffing situation with counterweight coupling, guarantee complete machine stability under the rotary drilling rig multifunction, can effectively reduce rig weight under the travel position.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is:
A kind of rotary drilling rig counterweight telescoping mechanism comprises revolving dial 1, telescopic oil cylinder 2, scalable counter weight device 3, and telescopic oil cylinder 2 two ends are connected with scalable counter weight device 3 with revolving dial 1 respectively.
Slideway is installed in described revolving dial 1 rear end, is convenient to telescopic oil cylinder 2 and regulates scalable counter weight device 3.
Described scalable counter weight device 3 built-in catchings and revolving dial 1 link together.
The operating principle of the utility model: to the weight of rotary drilling rig front end equipment, by plunger variable pump 5 output control oil, control valve 4 control telescopic oil cylinder strokes reach status requirement.
The beneficial effect of the utility model is: the equipment and the counterweight coupling that solve the rotary drilling rig multifunction; And under different luffing situation, mate with counterweight at same equipment; Guarantee complete machine stability under the rotary drilling rig multifunction, can effectively reduce rig weight under the travel position.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the hydraulic control schematic diagram of the utility model.
Wherein, 1-revolving dial, 2-telescopic oil cylinder, the scalable counter weight device of 3-, 4-control valve, 5-plunger variable pump.
The specific embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, the described a kind of rotary drilling rig counterweight telescoping mechanism of this specific embodiment comprises revolving dial 1, telescopic oil cylinder 2, scalable counter weight device 3, and telescopic oil cylinder 2 two ends are connected with scalable counter weight device 3 with revolving dial 1 respectively.
Slideway is installed in described revolving dial 1 rear end, is convenient to telescopic oil cylinder 2 and regulates scalable counter weight device 3.
Described scalable counter weight device 3 built-in catchings and revolving dial 1 link together.
Shown in Figure 2 is the hydraulic control schematic diagram, and plunger variable pump 5 provides the power oil sources, control telescopic oil cylinder under control valve 4 effects, and control valve 4 is in meta, and telescopic oil cylinder 2 is in locking state; Control valve 4 is in the A position, and telescopic oil cylinder 2 stretches out; Control valve 4 is in 2 withdrawals of B position telescopic oil cylinder.
The beneficial effect of this specific embodiment is: the equipment and the counterweight coupling that solve the rotary drilling rig multifunction; And under different luffing situation, mate with counterweight at same equipment; Guarantee complete machine stability under the rotary drilling rig multifunction, can effectively reduce rig weight under the travel position.
