Abstract
The utility model discloses an universal connection festival for asphalt spraying car lift system, including spindle nose, nut and end cap, spindle nose one end is the spheroid, and the other end is used for connecting, the nut cover is on the spheroid, and the nut is convex with spheroid contact segment, and the circular arc diameter is the same with the spheroid, end cap one end is the hemisphere nest, and hemisphere nest diameter is the same with the spheroid, end cap and nut pass through threaded connection formation ball socket and lock the spheroid displacement, and the spheroid can rotate in the ball socket. The utility model discloses spheroid and ball socket cooperation have the oil storage tank, and the spindle nose rotates in a flexible way and has the lubricating function, end cap and nut and threaded connection, convenient assembling, the spring pin location, the guarantee end cap can not drop, whole universal connection saves simple structure, connects reliably for asphalt spraying car lift system with greatly reduced lift system fault rate and cost of maintenance, improves asphalt spraying car efficiency of construction.
Description
Technical field
This utility model relates to a kind of engineering machinery attachment structure, particularly relates to the universal connecting joint of the lifting system of a kind of pitch sprinkling car, synchronous sealing rubble car。
Background technology
Pitch sprinkling car is as a kind of equipment spraying Colophonium, its spray bars requirement for height overhead is adjustable, requiring during transition that spray bars is overhead higher, and need the ground clearance different according to different construction regulating working conditions when spraying, the function of spray bars up-down adjustment is realized by promoting system。Traditional lifting system is generally made up of cylinder, oscillating bearing and lifting arm; oscillating bearing plays the effect connecting cylinder and lifting arm; phenomenons such as coming off, tear often occurs due to oscillating bearing; the fault rate causing lifting system is higher; thus affecting pitch sprinkling car efficiency of construction, increase maintenance cost。
Summary of the invention
For above-mentioned prior art Problems existing, this utility model provides a kind of universal connecting joint promoting system for pitch sprinkling car, simple in construction, connects reliable, is substantially reduced lifting system failure rate and maintenance cost, improves pitch sprinkling car efficiency of construction。
To achieve these goals, the technical solution adopted in the utility model is: a kind of universal connecting joint promoting system for pitch sprinkling car, including spindle nose, nut and plug；Described spindle nose one end is spheroid, and the other end is used for connecting；Described nut sleeve is on spheroid, and nut and spheroid contact portion are circular arc, and arc diameter is identical with spheroid；Described plug one end is half ball-and-socket, and half ball-and-socket diameter is identical with spheroid；Plug and nut are threaded connection formation ball-and-socket and spheroid displacement are locked, and spheroid can rotate in ball-and-socket。
This utility model is further, and half ball-and-socket circumference of described plug has oil storage tank。
This utility model is further, and plug and nut assemble post-treatment through hole, inserts resilient key and fixes, and ensures that plug does not fall off。
Compared with prior art, this utility model spheroid and ball-and-socket are joined and are associated with oil storage tank, and spindle nose rotates flexibly and has lubricating function；Plug and nut thread connect, easy to assembly, and resilient key positions, and ensure that plug does not come off；Whole universal connecting joint simple in construction, connects reliable, promotes system for pitch sprinkling car, will be substantially reduced lifting system failure rate and maintenance cost, improve pitch sprinkling car efficiency of construction。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1, spindle nose, 1-1, spheroid, 2, nut, 3, plug, 3-1, oil storage tank, 4, resilient key。
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail。
As it is shown in figure 1, this utility model promotes the universal connecting joint of system for pitch sprinkling car, including spindle nose 1, nut 2 and plug 3；Described spindle nose 1 one end is spheroid 1-1, and the other end is used for connecting；Described nut 2 is enclosed within spheroid 1-1, and nut 2 and spheroid 1-1 contact portion are circular arc, and arc diameter is identical with spheroid 1-1；Described plug 3 one end is half ball-and-socket, and half ball-and-socket diameter is identical with spheroid 1-1, and plug 3 and nut 2 are threaded connection formation ball-and-socket and can spheroid 1-1 displacement lock, but spheroid 1-1 can rotate in ball-and-socket。
On said structure basis, half ball-and-socket circumference of described plug 3 has oil storage tank 3-1。Before assembling, grease is smeared at the spheroid 1-1 place of spindle nose, and the ball-and-socket at spheroid 1-1 place has oil storage tank 3-1, thus ensureing that the rotation of spindle nose 1 is flexible。
Plug 3 and nut 2 assemble post-treatment through hole, insert resilient key 4 and fix, and screw threads for fastening and resilient key 4 positioning and locking between plug 3 and nut 2 ensure that plug 3 does not fall off。
When universal connecting joint promotes system for pitch sprinkling car, plug 3 one end connects cylinder, and spindle nose 1 one end connects lifting arm, and spindle nose 1 can rotate at certain angle, thus reducing cylinder and the requirement of lifting arm axiality。Owing to spheroid 1-1 place ball-and-socket is an enclosed construction and can lubricate, screw threads for fastening and resilient key positioning and locking between plug 3 and nut 2, therefore this universal connecting joint connects reliable。
Certainly, above-described embodiment is only preferred version of the present utility model, is specifically not limited thereto, and can make pointed adjustment on this basis according to actual needs, thus obtaining different embodiments。Owing to mode in the cards is more, just no longer illustrate one by one here。
