Abstract
The invention aims to relate to a chassis with a caterpillar structure. In a drag chain device of a rotary drilling jig, a thrust wheel assembly and a chain support block assembly are adopted to replace a drag chain wheel component in the original structure, so the maintenance cost for early damage of equipment is reduced. The drag chain device of the rotary drilling jig comprises a caterpillar, a chain support block, the thrust wheel assembly and other components; and the bearing capacity of the support wheel assembly is considerably larger than that of the drag chain wheel component in the original structure, while the cost of the drag chain wheel is much lower than that of an original component, and under the condition that the cost is slightly increased, the reliability of the device is improved greatly. An adjusting gasket in the drag chain block assembly comprises a rectangular thin steel plate and two parallel U-shaped holes with opened sides; the beginning circle center positions and the diameters of the U-shaped holes are consistent with those of the two circular holes in the lower end surface of a wear plate; and openings of the U-shaped holes face the same side, and are perpendicular to the connection line between the two semicircular holes. When the chain support block assembly is assembled, the adjusting gasket is positioned in the position of the lower end surface of the wear plate, and the openings of the U-shaped holes face the inner side of a longitudinal beam, so as to facilitate in-time adjustment, replacement and maintenance operation.
Description
Technical field
The present invention relates to contain the rotary drilling rig chassis of crawler belt and holder chain structure, can reach quite big caterpillar wheel by using carrying, and the desirable adjusting pad assembly of cost replaces respectively in the middle of it and the new drag chain device of two side position upper track wheels.Guarantee this chassis towing chain mechanism reliable in function, working service is convenient, and top section height of crawler position is easy to adjust, and greatly prolongs the failure-free production time of all kinds of engineering machinery chassis that contains crawler belt and holder chain structure.
Background technology
At present, high-order each link motion of section track rail assembly is smooth-going in order to ensure being arranged in, reduce the impact in this chassis walking process to greatest extent, and the parts depreciation between track rail assembly, great majority contain the top of crawler belt parts engineering machinery chassis longeron, be equipped with crawler belt holder chain structure, and mainly formed by some upper track wheel parts.Along with the increase of this chassis wheelspan, the quantity of its upper track wheel also can increase thereupon by a certain percentage.
Contain frequently emerging of caterpillar belt structure construction machinery and equipment along with big-and-middle-sized, its chassis load is considered the safety of complete machine operation also in continuous increase, and its wheelspan (horizontal throw at chassis drive wheel and track adjusting wheel center) also can strengthen thereupon.Will inevitably cause track length simultaneously, the increase of track takeup mean effort, and the significantly increase of instant impact in the driving process of chassis thereupon.And the load that is in crawler belt top section drag chain structure also can be the certain proportion rising undoubtedly, upper track wheel parts in the former drag chain structure (especially being positioned at the parts at these structure two ends), its actual load increasing degree is quite big, and be difficult to grasp, the phenomenon of damaging often appears in its two outsides upper track wheel in actual use.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, cost is desirable, reliable and practical, can be widely used in the rotary drilling rig drag chain device that various construction machinery and equipments contain the caterpillar belt structure chassis.
The object of the present invention is achieved like this: this device is made up of parts such as caterpillar wheel assembly, longeron, supporting chain block assembly, track rail assemblys.The caterpillar wheel assembly of replacement holder sprocket wheel is installed in the top of longeron, and be in the both sides of supporting chain block assembly, the supporting chain block assembly is installed on the bent plate of longeron, and by its pin feature remain with bent plate between in the vertical direction unsteady connection, track rail assembly is wrapped in the outside of parts such as caterpillar wheel assembly, supporting chain block assembly and longeron.
Supporting chain block assembly in the described device, by assembling after some adjustment pads and two pins and the wear plate welding, adjusting pad constitutes by rectangle sheet steel and two and to the U-shaped hole that a side is opened, the size of its initial home position in U-shaped hole and diameter, consistent with two circular holes of wear plate lower surface, its opening is towards homonymy, and perpendicular to the line of two semicircle orifices.When being assembled into the supporting chain block assembly, adjust the position that pad is in the wear plate lower surface, the opening in its U-shaped hole is in time adjusted and the operation of changing with convenient towards the inboard of longeron.Longeron is framing member, plane is positioned at position intermediate and is welded with the flute profile bent plate on it, this bent plate slit opening towards the last plane of longeron and with its upper cover plate weld together, process two borehole structures on the plane corresponding with opening, weld its position, back up, to make things convenient for the installation of the overhanging pin of supporting chain block assembly; And guarantee that the supporting chain block assembly is in the on-fixed state all the time in short transverse.
Longeron in the described device, the cover plate at last Plane Installation two caterpillar wheel places has rectangular opening, and is welded with the reinforcement bent plate in the lower surface of this position cover plate, two rectangular openings of this bent plate baseplane symmetrical distribution, there is a borehole structure its center.
During installation, at first as required the caterpillar wheel on the longeron baseplane, and other related components and the longeron of front and back position are mounted to one, again longeron is placed on the track rail assembly of having paved, then be positioned at two caterpillar wheels and the supporting chain block assembly on plane on the longeron successively, and guarantee in the supporting chain block assembly to adjust the U-shaped opening of pad, towards the inboard of longeron; Finish the installation of track rail assembly at last.The caterpillar wheel assembly is installed at the two ends of this device, and midway location is installed the supporting chain block assembly, also can be replaced by the caterpillar wheel assembly.
Advantage of the present invention is arranged in all kinds of chassis of the above towing chain mechanism in three places containing caterpillar belt structure and needs, is reliability, the raising overall economic efficiency of guaranteeing this mechanism, uses caterpillar wheel assembly and supporting chain block assembly to replace upper track wheel parts in the former mechanism respectively.Not only greatly reduce the equipment maintenance cost of damage too early, when the wear plate in the use supporting chain block assembly occurs under the situation of wearing and tearing, suitably retraction is installed in the track takeup in the longeron, and the height of the local caterpillar block of lifting a little, can in time increase the wear plate of adjusting pad or more renewing, guarantee that drag chain structure section track rail assembly height is consistent; The height of longeron top flute profile bent plate has been determined the height coordinate of this supporting chain block assembly, with the pin of wear plate weld together and the circular hole on this bent plate, has realized the fixing of this supporting chain block assembly planimetric position.Just by means of the effect of pin in this assembly, thereby guarantee that this device possesses simple in structure, dependable performance, characteristics easy to maintenance.Be described further below in conjunction with drawings and Examples.
