Description

A kind of rotary drilling rig

Technical field

The utility model relates to a kind of special-purpose construction machinery of being engaged in the pile foundation pore-forming operation in the engineerings such as road and bridge, worker China Democratic National Construction Association that is widely used in, and relates in particular to a kind of rotary drilling rig.

Background technology

Rotary drilling rig is the following earthward pore-forming equipment of holing of special use that rises in recent years, hole, and especially big darker its verticality of pore-forming all has the corresponding standard requirement.Now, little grade rotary drilling rig does not generally possess into the comprehensive adjustment function of hole perpendicularity, is difficult to satisfy the hole quality requirement of engineering in the construction.The rotary drilling rig of big grade it become the comprehensive adjustment function of hole perpendicularity that two kinds of technical solutions are only arranged at present: 1. rely on two oil cylinders of lower mast to be skew back is controlled lower mast with verticality from its relative motion to angle with lower mast; 2. set up two fuselage transverse horizontal at drilling machine platform in addition and adjust the verticality that oil cylinder is worked in coordination with lower mast oil cylinder adjustment pore-forming.The former lower mast cylinder force complexity is easily sent out fault; The structure of latter's rig is complicated relatively, manufacturing cost is higher.

Rotary drilling rig generally all is equipped with major and minor two kinds of winding plants.The master winch drilling rod that rises and falls uses frequently, is the requisite functional device of rig; Secondary elevator is stopped using when the normal bore operation of rig, only assists lift heavy (mobile drilling tool, casing etc.) time to use once in a while.Though secondary elevator load is little, utilization rate is low, rig is now still made a complete functional device and is equipped with, and the complicated thus structure of rig has increased the cost of rig.

Substantially the rotary drilling rig that has two kinds of Design Modes in the market: 1. complete machine each several part structure is all taked special-purpose design and manufacturing; 2. selecting for use Other Engineering machinery (as hydraulic crawler excavator) to form chassis special through in a big way structure, the system reform carries out supportingly assembling with the parts of design in addition (first-class as lower mast, drilling rod, power) again.No matter be though that the rotary drilling rig function specialty, performance of which kind of Design Mode is suitable for, structure is numerous and jumbled, involve great expense, function singleness, versatility are relatively poor.

Summary of the invention

In order to solve the above problems, it is low that the purpose of this utility model provides a kind of cost, and structure is simple relatively, rotary drilling rig simple to operate.

To achieve the above object, the utility model has adopted following technical scheme: a kind of rotary drilling rig, comprise revolving and scrape out aperture apparatus and scrape out the excavator body that aperture apparatus links to each other with revolving, described revolving scrapes out aperture apparatus and comprises two bearing diagonal oil cylinders and body frame assembly, the front end of body frame assembly is hinged on the lower end of secondary lower mast by the lower mast transverse axis, the upper end of secondary lower mast is hinged on the middle part of king post by vertical main shaft, fixedly connected with king post with the jackscrew that the location is used as by fastening bolt in the lower end of secondary lower mast, king post is provided with pushing oil cylinder and unit head, and described unit head is attached on the slide rail of king post and links to each other with described pushing oil cylinder; The middle vacancy of described unit head also is provided with the drilling rod assembly, and the upper end of drilling rod assembly links to each other with the hoisting rope of the pulley that is located at the king post upper end, on the two ends all hinged body frame assembly of difference and secondary lower mast of described two bearing diagonal oil cylinders.

Above-mentioned unit head both sides are provided with auxiliary suspension hook.

Because the utility model has adopted the structure design of simple major and minor double-mast, and then the effect that can utilize gravity realizes horizontal vertical adjustment function, the stress of lower mast oil cylinder has not only simplified the structure but also has improved, can not only make rig be suitable for the requirement of high accuracy pore-forming easily, and convenient and reliable operation, cheap.

The specific embodiment

Make a detailed explanation below in conjunction with 1-5 pairs of specific embodiment of the present utility model of accompanying drawing.

Embodiment: a kind of rotary drilling rig comprises revolving scraping out aperture apparatus and scraping out the excavator body 13 that aperture apparatus links to each other with revolving.Revolve and scrape out aperture apparatus and comprise two bearing diagonal oil cylinders 6 and body frame assembly 7, to revolve body frame assembly 7 corresponding sites that scrape out aperture apparatus and aim at excavator body 13, insert body frame respectively and connect minor axis 11 and be connected major axis 12 with body frame, make to revolve to scrape out aperture apparatus and the excavator body unites two into one.The front end of body frame assembly 7 is hinged on the lower end of secondary lower mast 5 by lower mast transverse axis 8, the upper end of secondary lower mast 5 is hinged on the middle part of king post 1 by vertical main shaft 3, fixedly connected with king post 1 with the jackscrew 15 that the location is used as by fastening bolt 14 in the lower end of secondary lower mast 5, king post 1 is provided with pushing oil cylinder 9 and unit head 4, and unit head 4 both sides are provided with auxiliary suspension hook 16.Described unit head 4 is attached on the slide rail of king post 1 and links to each other with described pushing oil cylinder 9; The middle vacancy of described unit head 4 also is provided with drilling rod assembly 2, and the upper end of drilling rod assembly 2 links to each other with the hoisting rope 10 of the pulley that is located at king post 1 upper end, on the two ends all hinged body frame assembly 7 of difference and secondary lower mast 5 of described two bearing diagonal oil cylinders 9.

The utility model when realizing double-mast transverse gravity vertical adjustment, rig moves to work plane will desire location, driller's journey hole after, extend bearing diagonal oil cylinder 6, make 5 one-tenth vertical stand-up states of king post and secondary lower mast; Unit head 4, drilling rod assembly 2 are dropped to the lower end of king post 1, unclamp the fastening bolt 14 of fastening major and minor lower mast and the jackscrew 15 of secondary lower mast 5 both sides; King post 1 secondary relatively automatically lower mast 5 under the effect of gravity finally is still in horizontal plumbness to swinging around vertical main shaft 3; Tighten fastening bolt 14 this moment again, makes major and minor lower mast connect one, the jackscrew 15 of secondary lower mast 5 both sides tightened to make king post 1 location again, promptly realized the horizontal vertical adjustment function of rig double-mast.

When rig need be assisted lift heavy, decline unit head 4 with weight, hung on the suspension hook 16 of unit head 4 both sides as the lifting rope of casing 17, and rising unit head 4 is realized the auxiliary lift heavy function of the no elevator of rigs.
