Abstract
The utility model discloses a lifting mechanism of a rotary drilling rig, belonging to the lifting mechanism of engineering machinery. The lifting mechanism of the rotary drilling rig comprises lifting oil cylinders, a support frame, a variable-amplitude oil cylinder, a variable-amplitude support frame, a base and a drilling mast; two ends of the base are respectively connected with the support frame and the variable-amplitude support frame; two ends of the support frame are respectively connected with a lifting oil cylinder; the other ends of the two lifting oil cylinders are both connected to the upper end of the drilling mast; and the other end of the variable-amplitude support frame is connected with the lower end of the drilling mast; and the variable-amplitude oil cylinder is connected between the support frame and the variable-amplitude support frame. The lifting mechanism of the rotary drilling rig has the following advantages: 1. the support is simple in structure, the structure is simplified, the support is easier to produce and mount, and meanwhile, space is saved, and the space layout is more reasonable; 2. the volume is small, the weight is light, materials are saved, the weight of the whole machine is reduced, and the cost is lowered; and 3. the stress distribution tends to be reasonable, and the situation of material waste is reduced.
Description
Technical field
The utility model relates to a kind of lifting mechanism of engineering machinery, particularly a kind of rotary drilling rig lifting mechanism.
Background technology
Revolve and dig the stake worker construction equipment that brill is a kind of advanced person, have characteristics such as quality height, duration weak point, thereby be widely used in the pore-forming perfusion of pile foundation constructions such as construction of road and bridge, building operations, urban construction construction.The rotary drilling rig lifting mechanism is one of core institution of rotary drilling rig; Play and support the rotary drilling rig weight of getting on the bus; Effects such as the work range of adjusting brill mast and duty; Thereby the key parameter to the measurement complete machine performances such as accuracy in hole in the radius of clean-up of rotary drilling rig, the drilling construction process had decisive influence, simultaneously complete machine layout and stability also there are fundamental influence.At present, the rotary drilling rig of high pulling torque is in order to improve the stability of boring mast, and the support frame structure of elevating ram rear end is complicated, volume is big, weight is big.
Summary of the invention
The purpose of the utility model is to provide a kind of: light weight, Stability Analysis of Structures, rational rotary drilling rig lifting mechanism.
The purpose of the utility model is achieved in that the rotary drilling rig lifting mechanism comprises elevating ram, bracing frame, amplitude oil cylinder, luffing support, base and brill mast; Be connected with bracing frame and luffing support respectively at the two ends of base; Two ends of bracing frame respectively connect an elevating ram, and the other end of two elevating rams all is connected the upper end of boring mast; The other end of luffing support is connected with the lower end of boring mast, between bracing frame and luffing support, is connected with amplitude oil cylinder.
Beneficial effect, owing to adopted such scheme, what rotary drilling rig bored mast vertically is to adjust through the flexible of amplitude oil cylinder; Stretching of amplitude oil cylinder, thus the operating attitude of gyration realization adjustment brill mast is carried out in the motion of drive luffing support around the pin joint of luffing support and base.Elevating ram role in the rotary drilling rig course of work is a stabilization, guarantee to bore mast do not occur rock.When rotary drilling rig carried out the transition of duty and travel position, elevating ram was elongated to maximum, and the brill mast is turned forward, and up to level, at this moment, elevating ram is done gyration around the hinge point of elevating ram and bracing frame.Light weight, Stability Analysis of Structures, has rationally reached the purpose of the utility model.
The utility model project organization is rationally distributed, satisfies under the prerequisite of condition of work in assurance, has reduced the weight of lifting mechanism, and stress is reasonable.Its advantage has: 1, supporting structure is simple, simplifies the structure, and is easier to produce install, and saves the space simultaneously, makes space layout more reasonable; 2, volume is little, and is in light weight, saves material, reduces complete machine weight, reduces cost; 3, stressed distribution more is tending towards rationally having reduced the waste of material situation.
Description of drawings
Fig. 1 is the construction profile of the utility model.
Fig. 2 is the structure chart of the utility model.
Among the figure, 1, elevating ram; 2, bracing frame; 3, amplitude oil cylinder; 4, luffing support; 5, base; 6, bore mast.
The specific embodiment
Through embodiment the utility model is done further explain below in conjunction with accompanying drawing.
Embodiment 1: the rotary drilling rig lifting mechanism comprises elevating ram 1, bracing frame 2, amplitude oil cylinder 3, luffing support 4, base 5 and bores mast 6; Be connected with bracing frame 2 and luffing support 4 respectively at the two ends of base 5; The other end that two ends of bracing frame 2 respectively connect 1, two elevating ram 1 of an elevating ram all is connected the upper end of boring mast 6; The other end of luffing support 4 is connected with the lower end of boring mast 6, between bracing frame 2 and luffing support 4, is connected with amplitude oil cylinder 3.
Be characterized in: support component, luffing parts and the stable triangular structure of brill mast 6 common compositions; Elevating ram 1 plays main stabilization with bracing frame 2 in the rotary drilling rig course of work.Amplitude oil cylinder 3 can be adjusted the amplitude of variation of boring mast with luffing support 4, and it is vertical that mast is bored in control.Base 5 is the main supporting part and the fixed pedestals of getting on the bus.
