Abstract
The invention relates to a chassis of a rotary drilling machine and discloses an H-shaped bottom frame structure of the rotary drilling machine. The H-shaped bottom frame structure of the rotary drilling machine is formed by parts such as a left longitudinal beam, a right longitudinal beam, an H-shaped bottom frame, a blocking pin, a pin shaft and an extensible oil cylinder. The H-shaped bottom frame structure of the rotary drilling machine has the advantages of enabling a part structure to be simplified and being reasonable in manufacturability of the manufacturing process due to the fact that a completely symmetrical appearance design is employed to the H-shaped bottom frame; enabling the welding process to be easy to achieve and effectively reducing the manufacturing cost due to the facts that two square case structures are respectively arranged on the left longitudinal beam and the right longitudinal beam which are arranged on bilateral sides of the bottom frame, the left longitudinal beam and the right longitudinal beam are sleeved outside a hanging arm structure which is formed by external extension of the bottom frame, and the square cases with enlarged structural sections and shortened lengths replace original lathy hanging arm structures; and guaranteeing that assembling procedures of large structural components are easy to achieve due to welding seam chamfers which are formed on upper internal portions and lower internal portions of the square cases of the longitudinal beams and a special design that the chamfers are assembled on adjusting plates which are arranged on a front end face and a rear end face of the bottom frame.
Description
Technical field
The present invention relates to contain the rotary drilling rig chassis of H shape Undercarriage structure, by handling left-right longeron transversal stretching oil cylinder, force H shape underframe with left-right longeron relative slippage to take place, in rotary drilling rig construction period, reach the purpose that crawler belt remains Breadth Maximum.Thereby guarantee this rig job stabilization, the cost that improves drilling accuracy to greatest extent and effectively reduce construction.
Background technology
At present, in order to ensure the stability between the rotary drilling rig operational period and convenient long-distance transfer transportation, the extension type longitudinal beam structure is all adopted on most of chassis of this kind equipment.After this rig enters the construction site, at first finish being installed in the overhanging of left-right longeron telescopic oil cylinder on the underframe, force its two side girder of underframe to reach maximum outer wide size, and then this rig is carried out the manipulation of other action.When needing long-distance transition to enter another site construction finishing a certain engineering, before the climbing flat bed transport vehicle, be in full reduced time state of oil cylinder in level and the jib lubbing mechanism boring mast, also need to operate the longeron telescopic oil cylinder to the minimum length size.
Be installed in the underframe in the rotary drilling rig chassis, generally formed by square chest and the left-right longeron of centre.The front/rear end of square chest leaves the bearing that longeron telescopic oil cylinder and locking pull bar are installed, and each design of its both sides has two rectangular openings to insert with the supporting leg that makes things convenient for the left-right longeron cantilever construction, realizes the smooth assembling of this underframe.In the welding process of processing and manufacturing, because left-right longeron cantilever construction position deflection is difficult to control, the phenomenon of assembling difficulty often appears.
Summary of the invention
It is stronger, easy for installation to the purpose of this invention is to provide a kind of welding deformation ability simple in structure, anti-, can be widely used in the rotary drilling rig H shape Undercarriage structure of various engineering machinery chassis.
The object of the present invention is achieved like this: this device is made up of component such as left longeron, right vertical beam, H type underframe, longeron telescopic oil cylinders.Left-right longeron is installed in the both sides of H shape underframe, its square chest structure is corresponding being enclosed within on the cantilever of H shape underframe homonymy respectively, described telescopic oil cylinder is installed in this underframe, tailpiece of the piston rod by bearing pin respectively with the left-right longeron square chest in support hinged, shrouding is installed on the outer face of longeron square chest, the tight tailpiece of the piston rod that covers oil cylinder, movable cushion block are installed in the longeron upper surface and are positioned at the middle part of longeron two square chest structures.
Left-right longeron in the described structure, the alloy-steel plate by some different-thickness is welded respectively.Its baseplane and rearward end can be installed thrust wheel and driving speed reducer respectively through machining, and front end has also designed the guide wheel mount pad, and there are two square chest structures at the middle part, and the outer end near this square chest also is provided with supporting structure in the center of its base plate; Bent plate has also been designed on the last plane in two square chest centre positions, and integrally welded with the upper cover plate of longeron, leaves two borehole structures on this bent plate top planes.Be positioned at the last lower plane of square chest structure inboard and be welded with backing plate respectively near its inner face, with the integrally welded backing plate of base plate on uniform if borehole structure can store certain lubricating grease, to reduce the resistance during the relative slip with longeron of underframe.
Movable cushion block in the described structure is welded by two pins and wearing plate, and the size of plane bent plate two circular holes adapts on the diameter of its pin and position and the longeron.
H type underframe in the described structure is symmetrical structure, on the base plate of its rectangular cantilever beam and be positioned at the position of bilateral symmetry plane, design has longeron telescopic oil cylinder mounting bracket, this support has circular hole and thread pore structure, the cylinder barrel journal stirrup of this oil cylinder is fixed on the centre of this support by means of bearing pin, pressing plate and screw.One end of this bearing pin has boss structure, and the external diameter of its boss is greater than the size of its support Circularhole diameter, and also there is the groove structure that can hold platen width in the end face of its boss.Before and after the H type underframe with end face that longeron matches on, be symmetrically welded with four and adjust plates, the chamfering structure of convenient installation is all designed in the outer end that is positioned at this plate.
During installation, at first H type underframe is placed on the suitable supporting object, component such as longeron telescopic oil cylinder, bearing pin, pressing plate and screw are installed immediately, left-right longeron is installed respectively then, and guarantee the journal stirrup of all oil cylinder piston bars, all realize with longeron between reliable the connection.At last finish being connected and fixed between shrouding, movable cushion block and the longeron more respectively, and the locking that thereupon uses lock pin to finish between H type underframe and the longeron is operated.
Advantage of the present invention, underframe have adopted the design of complete symmetry, cause design of part greatly to be simplified, and the manufacturability of its manufacture process is greatly improved, and welding deformation is controlled easily; Compare left-right longeron length dimension shortens dramatically the elongated cantilever construction of square chest replacement to increase cross dimensions with original structure, and welding procedure is easy to implement, has reduced manufacturing cost.Longeron and underframe assemble the specially design of chamfering in addition, thereby guarantee the simplification of large-sized structural parts assembly technology, and assembling procedure is able to smooth implementation, reduces manufacturing cost to greatest extent.
Be described further below in conjunction with drawings and Examples.
