Description
Technical field
The present invention relates to the dismountable combined, extended gooseneck boom of a kind of rotary drilling rig, belong to container field of engineering technology.
Background technology
Rotary drilling rig is as a kind of pile foundation pore-forming implement, and it mainly drives drill rod boring tool rotation to cut soil by unit head, then by master winch, promotes drill rod boring tool and unload soil to hole, and loop cycle operation finally completes the construction of a work.At rotary drilling rig master winch, promote in the process of rod bit the effect that gooseneck boom plays wire rope guiding and supports in whole Hoisting System.In recent years, along with across being on the increase of river, the Longspan Bridge engineering such as over strait, for the supporting capacity of pile foundation of bridge pier plinth, require constantly to increase, and use major diameter, the super dark pile foundation of rotary drilling rig construction to become main solution.
At present, domestic all rotary drilling rig gooseneck booms are Integral welded structure, and this structure mainly exists following three problems: 1, run into when bore diameter need to be expanded and gooseneck boom frame is out of shape, need to change whole gooseneck boom assembly, workload is large, and replacement cost is high; 2, along with the continuous quickening of domestic stake construction equipment multifunction developing steps, between different engineering methods, use same main frame, only need to change that different operating device can realize is a kind of development trend, and existing Integral welded gooseneck boom cannot be realized general between different engineering methods, switch trouble, cost is high; 3, for especially big tonnage rotary drilling rig, because bore diameter is larger, the forward and backward pulley locating distance of gooseneck boom assembly is also longer, and installation accuracy need to be higher, also needs to utilize main equipment to process, and difficulty of processing is large, and cost is high.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides the dismountable combined, extended gooseneck boom of a kind of rotary drilling rig, and it is not only changed simply, replacement cost is low, and can between different engineering methods, realize generally, and autgmentability is strong; Easily processing simultaneously, cost is low.
To achieve these goals, the dismountable combined, extended gooseneck boom of a kind of rotary drilling rig of the present invention, comprises gooseneck boom main body, wire rope and two gooseneck boom pulleys, and gooseneck boom main body is arranged on the brill mast of rotary drilling rig; Also comprise front support stand and rear support stand, the dismountable front portion that is arranged on gooseneck boom main body of described front support stand; The dismountable rear portion that is arranged on gooseneck boom main body of rear support stand; Two gooseneck boom pulleys are arranged on respectively the two ends of back and front supporting frame by pulley pin shaft, between pulley pin shaft and back and front supporting frame, by bolt I, be fixedly connected with; The top of drilling rod walked around two gooseneck boom pulleys and is fixed on by wire rope.
Preferably, the center of described gooseneck boom pulley is provided with bearing, and bearing two ends are fixed on gooseneck boom pulley with back-up ring; Pulley pin shaft is through bearing.
Preferably, described front support stand is fixedly mounted on the front portion of gooseneck boom main body by rack pin shaft; Rear support stand is fixedly mounted on the rear portion of gooseneck boom main body by rack pin shaft; Between rack pin shaft and gooseneck boom main body, by bolt I, be connected.
Preferably, the edge of described gooseneck boom pulley is provided with rotating steel pipe, and the gap between steel pipe and gooseneck boom pulley is less than the diameter of wire rope; Described steel pipe is connected by bolt II and nut with back and front supporting frame.
Compared with prior art, the present invention is by adopting dismountable combined type design, in the situation that not changing wirerope-winding track, can realize the independent design of gooseneck boom main body and back and front supporting frame, simple in structure, back and front supporting frame all can be gooseneck boom main body independent disassembling, when same main frame bore diameter need to be expanded, only need to change front support stand and just can realize macropore and creep into, without changing again whole gooseneck boom assembly, reduced replacing workload and replacement cost; When rotary drilling rig main frame is realized other multiple engineering method construction, need to hang different equipments, in the situation that not changing gooseneck boom main body, this expansion gooseneck boom also can, by changing among a small circle, be realized fast and being switched, and it can be realized between different engineering methods general, reduced cost, autgmentability is strong; Meanwhile, for especially big tonnage rotary drilling rig, because gooseneck boom main body and back and front supporting frame are designs separately, therefore available mini-plant is processed respectively gooseneck boom main body and back and front supporting frame, and then be assembled into gooseneck boom assembly, and processing cost is low, and machining accuracy easily guarantees.Finally, can quick and conveniently realize the expansion of rotary drilling rig work range, realize macropore and creep into and revolve the switching of digging multi-functional configuration, change, maintenance cost is low, easy to process, precision is high, low cost of manufacture.
