Abstract
The invention relates to a clearance adjusting device for a frame of a rotary drilling rig, which is used for adjusting the clearance between a longitudinal beam and an H-shaped frame along the vertical direction by changing the screw-in length of bolts or replacing a nylon sliding block in chassis structures with adjustable crawler belt width for various large and medium-sized rotary drilling rigs. The clearance adjusting device consists of screws, the nylon sliding block, a pressure plate, the bolts, the H-shaped frame, the longitudinal beam and other parts. The clearance adjusting device has the beneficial effects that during the period of installation or equipment maintenance, the fit clearance between the frame and the longitudinal beam of the rotary drilling rig is always kept in a reasonable status at any time by adjusting the screw-in length of the bolts or replacing the nylon sliding block according to the size of the actual fit clearance between the frame and the longitudinal beam along the vertical direction; and the nylon sliding block and the pressure plate are placed in a long circular hole of the longitudinal beam under a floating condition, and the bolts play a role of limiting the up-down movement range of the nylon sliding block so as to ensure ideal fit clearance between the frame and the longitudinal beam.
Description
Technical field
The present invention relates to crawler type rotary drilling rig chassis,, adjust the structure of vertical gap between longeron and the H shape vehicle frame, be particularly useful for containing the chassis of plug-in body frame structure for automotive engineering machinery through length that changes the bolt screw-in or the nylon slide block that more renews.
Background technology
At present, in order to ensure the stability of complete machine between operational period, most of crawler type rotary drilling rigs all adopt the adjustable structure of crawler belt horizontal span.Equipment is in travel position, and left and right sides crawler belt outside width is withdrawn into minimum dimension, and desire gets into the construction state and then will all stretch out crawler belt, guarantees that its transverse width reaches maximum.The crawler belt span change process smoothly whether, will directly influence the operating efficiency of rotary drilling rig, and influence the principal element of this operating process, be that H shape vehicle frame and longeron embed (overlapping) position each other, whether the gap between the box structure reasonable.This excesssive gap, can draw between operational period revolve dug rig before/back or a left side/right-hand to rock, produce shock loading immediately, its result can have a strong impact on the stability of complete machine, even causes the vertical precision of boring overproof; The gap is too small will to cause the flexible difficulty of crawler belt again, even can't operation.
The parts on external this type of chassis of rotary drilling rig, its matching surface all adopt mach mode to guarantee that mutual fit clearance is less, and component are stressed comparatively reasonable.And of home make product owing to consider the restriction of manufacturing cost factor and large-sized processing equipment, mostly adopts welding, shaping and suitable mode of amplifying fit clearance to produce.Because this modular construction size is bigger, welding deformation control is not very good, and after the assembling of most of rotary drilling rigs chassis, all the fit clearance that can occur surpasses the phenomenon of allowed band, and the performance of rotary drilling rig is caused certain negative effect.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, reliable and practical; Be adapted to dissimilar rotary drilling rigs; The occasion that chassis structure spare vertical direction fit clearance need be adjusted; Can be widely used in the engineering machinery chassis product structure of the various H of containing shape vehicle frames, and the crawler belt horizontal span needs the frequent rotary drilling rig vehicle frame lash adjusting device that changes.
The objective of the invention is to realize like this: this device is made up of parts such as bolt, nylon slide block, pressing plate, nut, H shape vehicle frame, longerons.Nylon slide block is installed on the pressing plate and is placed in the slotted hole of longeron cover plate, realizes its scope of activities is limited through bolt, nut, plays the adjustment to H shape vehicle frame and longeron vertical direction fit clearance.This device is installed on four different positions of the left and right longeron of rotary drilling rig; A side that keeps nylon slide block all the time can with plane contact on the H shape vehicle frame; When vertical gap is excessive between this vehicle frame and the longeron, can realize the cooperation of best clearance through the adjusting of bolt screw-in length.
Nylon slide block in the said device is the strip structure, and the pit of some is left on the plane that contacts with H shape vehicle frame, can store the lubricating grease of some during installation, to improve the service condition of this slide block, reduces wear.The length of pressing plate is slightly larger than the size of longeron slotted hole, guarantees that part can not come off in the assembling process.
During installation, at first the H shape cantilever of vehicle frame is inserted in the corresponding rectangular box of longeron, again nylon slide block is fixed on the pressing plate, and is placed in the slotted hole of longeron cover plate.According to the actual size that forms the gap between H shape vehicle frame, the longeron, the screw-in length of adjustment bolt, fastening nut immediately.
Advantage of the present invention; Solve and have the chassis that rotary drilling rig contains flexible (span adjusting) structure of crawler belt now; The difficult problem that the gap can't be regulated between vehicle frame and the longeron; In assembling and use; Actual change (or wearing and tearing) situation according to fit clearance; Can adjust the screw-in length of bolt at any time or change nylon slide block, guarantee that its fit clearance maintains in the reasonable range.
Be described further below in conjunction with accompanying drawing and embodiment.
Description of drawings
Fig. 1 is one embodiment of the present of invention structure charts.
Fig. 2 is a sectional view among Fig. 1.
The specific embodiment
The overhanging cantilever of H shape vehicle frame (2) is inserted in the corresponding square chest of longeron (1); Nylon slide block (7) is fixed on the pressing plate (3) through screw (6); Immediately institute's assembled components is put into the slotted hole of longeron (1) cover plate; Nut (4) is installed on the bolt (5); Again bolt (5) is screwed in the corresponding screwed hole in longeron (1) upper end; And keep keeping certain clearance between end and the pressing plate (3) of bolt (5) fastening nut (4) immediately.
Claims (3)
1. one kind can be widely used in the adjustable chassis structure of big-and-middle-sized rotary drilling rig crawler width; Through length that changes the bolt screw-in or the nylon slide block that more renews; The rotary drilling rig vehicle frame lash adjusting device of vertical gap between adjustment longeron and the H shape vehicle frame; This device is by longeron; H shape vehicle frame; Pressing plate; Nut; Bolt; Screw; Nylon slide block is formed; It is characterized in that the nylon slide block in the said device is fixed on the pressing plate; And insert together in the slotted hole of longeron cover plate; Through changing the screw-in length of bolt, reach the purpose of vertical gap between adjustment H shape vehicle frame and the longeron.
2. rotary drilling rig vehicle frame lash adjusting device according to claim 1 is characterized in that nylon slide block is the strip structure, and a side also has the pit that stores lubricating grease.
3. rotary drilling rig vehicle frame lash adjusting device according to claim 1 is characterized in that the length of pressing plate is all more bigger than the length of longeron cover plate slotted hole and nylon slide block.
