Abstract
A kind of limit connection device, upper limit position block next-door neighbour lower position block, the upper surface of upper limit position block and the soffit of contact block have corresponding groove, spring is pressed with between upper limit position block and contact block, contact block is arranged in the groove of upper limit position block by bolt, before and after upper limit position block, two sides have rectangular bolt slot, the width of bolt slot is greater than bolt outside dimension, ensure that bolt can slide up and down in rectangular bolt slot, coil component spring bore is had in groove, the diameter dimension of coil component spring bore is greater than the outside dimension of spring, ensureing that spring can easily be put into installs in groove up and down.The invention has the beneficial effects as follows: the way of contact improving limited block and loading machine side dumping bracket, ensure that bracket both sides limited block contacts with bracket simultaneously, common bearing load, and play certain damping effect, improve the application life of bracket, thus reach the application life of improving side dumping working device, improve the competitiveness of product in market.
Description
Technical field
The present invention relates to a kind of stopping means of loader, especially the limit connection device of side-dump loader scraper bowl and bracket.
Background technology
Loader belongs to earth moving machinery class, is that a kind of by being arranged on the complete scraper bowl braced structures in one, front end and connecting rod, random device travels forward and carries out loading or excavating, and promote, the self-propelled crawler belt of transport and unloading or tire machinery.Side-dump loader is as one of them important branch, play an important role in actual production, current side-dump loader equipment forms primarily of side dumping scraper bowl, side dumping bracket, rocking arm, swing arm and connecting rod, the stuctures and properties of equipment directly affects working size and the performance parameter of complete machine, therefore, the reasonability of equipment directly affects the time, engine power etc. of the production efficiency of loader, live load, power and the operation effectiveness under kinetic characteristic, different operating mode, working cycles.The design key point of side dumping working device and difficult point are the spacing connected mode between side dumping scraper bowl and side dumping bracket, and therefore, the form of structure of limited block produces directly impact by the performance of equipment.The spacing connected mode that current most of producer adopts relies on to carry out spacing connection with the limited block of central axis symmetry to side dumping scraper bowl and side dumping bracket, and each limited block is divided into two panels limited block identical up and down.This structure affects larger by processing and manufacturing factor, limited block is caused to be separated with bracket under serious conditions, even if mismachining tolerance is in regulation requires, but in the course of the work, side dumping scraper bowl and side dumping bracket are constantly turned on one's side and are opened with closed, limited block and side dumping bracket contact site is caused constantly to wear and tear, side limited block is finally caused to be separated with bracket, no longer contact, one-sided limited block is only had to work, direct result is that operating load all acts on bracket and swing arm articulated position place, because load is excessive, this articulated position place is easily caused to ftracture, reduce the application life of equipment.
Summary of the invention
The object of this invention is to provide and a kind ofly can improve side-dump loader application life, ensure side dumping scraper bowl and the hinged solid and reliable limit connection device of side dumping bracket.
The object of the present invention is achieved like this: upper limit position block next-door neighbour lower position block, the upper surface of upper limit position block and the soffit of contact block have corresponding groove, spring is pressed with between upper limit position block and contact block, contact block is arranged in the groove of upper limit position block by bolt, before and after upper limit position block, two sides have rectangular bolt slot, the width of bolt slot is greater than bolt outside dimension, ensure that bolt can slide up and down in rectangular bolt slot, coil component spring bore is had in groove, the diameter dimension of coil component spring bore is greater than the outside dimension of spring, ensureing that spring can easily be put into installs in groove up and down.
The invention has the beneficial effects as follows: when keeping limited block appearance and size substantially constant, improve the way of contact of limited block and loading machine side dumping bracket, make up the situation that the limited block that causes due to reasons such as mismachining tolerances cannot contact or only have a limited block to contact with bracket with bracket, ensure that bracket both sides limited block contacts with bracket simultaneously, common bearing load, and play certain damping effect, improve the application life of bracket, thus reach the application life of improving side dumping working device, improve the competitiveness of product in market.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
1 upper limit position block, 2 springs, 3 grooves, 4 contact blocks, 5 lower position blocks, 6 bolts, 7 bolt slots, 8 coil component spring bore in figure.
Detailed description of the invention
Embodiment: this limit connection device comprises upper limit position block 1, spring 2, groove 3, contact block 4, lower position block 5, bolt 6, bolt slot 7, coil component spring bore 8, upper limit position block 1 is close to lower position block 5, upper limit position block 1 groove 3 upper surface and contact block 4 soffit have equal and opposite in direction and have the coil component spring bore 8 of certain depth, four springs 2 are arranged between upper limit position block 1 and contact block 4, contact block 4 is arranged on upper limit position block 1 by the symmetrical bolt 6 in front and back two, before and after upper limit position block 1, two sides have the rectangular bolt slot 7 of certain length, the width of bolt slot 7 is slightly larger than bolt 6 outside dimension, ensure that bolt 6 can slide up and down in rectangular bolt slot 7.Upper limit position block 1 and bracket contact portion, top is divided into plane, and bottom is divided into the concentrically ringed partial arc consistent with contact site home position, and arc section and plane transition portion are tangent.The equal and opposite in direction that upper limit position block 1 groove 3 upper surface and contact block 4 soffit are offered also has the coil component spring bore of certain depth, its shape is circular, diameter dimension, slightly larger than the maximum outside diameter size of spring 2, ensures that spring 2 can easily be put into and installs in groove 3 up and down.Before and after contact block 4, both sides have screwed hole, be connected with upper limit position block 1 by two bolts 6, bolt 6 is arranged in rectangular bolt slot 7 corresponding on upper limit position block 1, the width of rectangular bolt slot 7 slightly larger than bolt 6 maximum outside diameter, should ensure that bolt 6 can realize sliding up and down in bolt slot 7.Upper limit position block 1 front and back sides offers the symmetrical rectangular slot with certain depth, when bolt 6 is pushed over groove top by spring 2, contact block 4 upper surface should exceed upper limit position block 1 groove 3 upper surface certain distance, ensure that upper limit position block 1 contacts with bracket, when bolt is compressed to bottom land end by external force, the soffit of contact block 4 should exceed upper limit 1 piece of groove 3 upper surface certain distance, ensures that spring 2 is not damaged by pressure.When being subject to External Force Acting, even if two symmetrical limited blocks can not contact, because the compressibility of spring 2 will be compressed, along with the compression of spring 2 on the side dumping scraper bowl after processing simultaneously, another contact block just realizes contacting with bracket, reaches the common passive object of two limited blocks.
