Description
Technical field
The present invention relates to a kind of lash adjusting device, especially a kind of lash adjusting device of construction machinery and equipment telescopic outrigger belongs to technical field of engineering machinery.
Background technology
In order to improve complete machine stability, through a leg mechanism complete machine is held up built on stilts usually and carry out operation during engineer machinery operation, for example a leg mechanism of car hosit, backhoe loader and heavy duty truck etc. bears complete machine deadweight and jerk when operation.Prop up leg mechanism and comprise pilot bar and guide cylinder, pilot bar can move up and down in guide cylinder, so that the ground-surface relatively height of adjustment complete machine.Pilot bar is easy to generate wearing and tearing in motion process, the gap between pilot bar and the guide cylinder is strengthened, and excessive clearance can influence the support effect and the mechanical stability of complete machine, even causes danger.Existing leg mechanism is directly through thread mechanism adjustment supporting leg internal clearance; Because the operating environment very severe of construction machinery and equipment; It is loosening that screw thread takes place the jerk that produces easily, and the adjustment of supporting leg internal clearance is unreliable, and screw thread corrosion rear support leg mechanism can't adjust.
European patent specification EP0867566 and EP1243706 disclose the abrasionproof pad of a kind of stabilizing leg and this supporting leg; This stabilizing leg adopts large diameter bolt and guide cylinder ingear mode; The bolt end directly is resisted against on the guiding extensible member; Adjust supporting leg in-to-in gap through the turn bolt, on bolt, also be provided with locking parts simultaneously, prevent bolt because jerk takes place loosening.But above-mentioned two parts of patent documents can't continue to regulate supporting leg in-to-in gap.Though the large diameter bolt of above-mentioned patent and extensible member area of contact are big, but the supporting leg internal clearance is effectively adjusted, but need bigger rotating torque when taking this mode to regulate the gap, manual shift wastes time and energy very much.And maintenance, dismounting are very difficult after the large diameter bolt corrosion.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to maintenance, time saving and energy saving supporting leg slack adjuster when regulating the gap.
The present invention is achieved through following technical scheme:
A kind of landing-lag gap adjusting device; Comprise guide cylinder, pilot bar, clearance adjustment mechanism, said pilot bar one end is captiveed joint with support, and the pilot bar other end puts in said guide cylinder endoporus; Flexibly connect with the guide cylinder endoporus, said clearance adjustment mechanism is arranged on lower end, the said guide cylinder outside.Said clearance adjustment mechanism comprises fixedly backing plate, back-up block, stay bearing plate, adjusting pad, interior adjustment piece, investigation mission outside the city or town monoblock, adjusting bolt; Said fixedly backing plate is arranged between said guide cylinder and the pilot bar; Said pilot bar one side is resisted against on the said fixedly backing plate; Said back-up block is arranged on and the fixing relative side guide cylinder of the backing plate outside, becomes the stay bearing plate of angle square shape to captive joint with guide cylinder.Form the back-up block cavity between back-up block and the stay bearing plate, said adjusting pad is arranged in the back-up block cavity, and adjusting pad one side is resisted against on the said back-up block facade.Superimposed being arranged in stay bearing plate endoporus and the outer cinclides of guide cylinder before and after adjustment piece, the investigation mission outside the city or town monoblock in said; Interior adjustment piece one side end face is passed the guide cylinder barrel and is resisted against on said pilot bar one side; Investigation mission outside the city or town monoblock opposite side end face is resisted against said adjusting pad opposite side; Said adjusting bolt passes said back-up block, adjusting pad, withstands on the adjustment piece opposite side end face.
The object of the invention can also further realize through following technical measures.
Aforesaid landing-lag gap adjusting device, wherein said adjustment piece center is provided with threaded connection hole.
Aforesaid landing-lag gap adjusting device, wherein said adjusting pad middle part is provided with inverted U-channel, and the adjusting bolt passes said inverted U-channel and withstands on the adjustment piece opposite side end face, and the adjusting pad lower end surface is a wedge shape.
Aforesaid landing-lag gap adjusting device, wherein said back-up block are that recording quantity, three faces surround structure, and the back-up block bottom is provided with brace table, and said adjusting pad is supported on the said brace table, and the back-up block top also is provided with arc groove.
The back-up block bottom is provided with brace table, and said adjusting pad is supported on the said brace table, and the back-up block top also is provided with arc groove.
The present invention is simple in structure; The mode that adopts adjusting pad to combine with threaded adjusting mechanism; The feasible bolt of regulating withstands on the adjustment piece, between back-up block and stay bearing plate, forms the back-up block cavity, and the adjustment piece is inserted in the interior filling of the cavity that forms between back-up block and the stay bearing plate and regulates the gap between pilot bar and the guide cylinder; Guide cylinder may be locked on the required height and position of pilot bar, and guide cylinder and pilot bar convenient for unlocking are freely.Adjustment piece and pilot bar area of contact are big, and the present invention holds out against the bigger adjustment piece of area through the minor diameter bolt, produce bigger positive pressure and cause the static friction force between guide cylinder and the pilot bar to increase, and make that locking is reliable between guide cylinder, the pilot bar.Can realize the adjusting in gap easily, effortlessly, avoid being difficult to after the existing large diameter bolt corrosion keeping in repair, the disadvantage of dismounting.
Advantage of the present invention and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
