Abstract
The utility model relates to a novel support lug structure used by various pieces of mechanical equipment with extreme compact structures in mine environments and capable of guaranteeing the implementation of daily maintenance of damageable pieces of the equipment in narrow space. The structure comprises a compressing box body, a compacting box body, a pin shaft, movable support lugs, and the like, wherein, the compacting box body is mounted at the inner part of the compressing box body; and a cylinder barrel at the back end of an oil cylinder of the compacting box body, which is provided with a single-support-lug structure, is mounted between the movable support lugs and fixed support lugs and hinged with the compressing box body through the pin shaft. According to the utility model, outer side support lugs in the integral double-support-lug supporting oil cylinder structure are changed to detachable and movable parts, and the position precision problem with the movable parts and the matched fixed support lugs is solved by relying on locating pins arranged on mounting surfaces of the movable support lugs; a spherical surface structure is used at the other end of the oil cylinder, so that the end of the oil cylinder, at which the support lugs are arranged, can swing and move backwards towards the only outer side of the oil cylinder after the movable support lugs and the locking pins are removed under the circumstance that the position of the oil cylinder is not changed, and the detachment operation of the parts of the oil cylinder is guaranteed.
Description
Technical field
The utility model relates in the very narrow space; Guarantee the device of the smooth dismounting of engineering machinery quick-wear part; The structure of ingenious each part of design and mounting type reduce component maintenance occupation space to greatest extent, have established condition easily for the operation and maintenance of machinery.Be particularly useful in the underground mine digging environment machinery equipment that overall structure is comparatively compact.
Background technique
At present; The support of tie component, connection in all mechanical structures mostly take the pull bar two ends to adopt single journal stirrup, and connected other parts use all-in-one-piece two ear structures; The tie rod end journal stirrup is placed the neutral position of two journal stirrups, realize connecting between the parts through bearing pin again.During dismounting, at first remove the bearing pin of pull bar one end or the connection of alternate manner, remove the component that are connected with pull bar simultaneously, for necessary space is reserved in the dismounting of accomplishing this pull bar.Then remove the link bearing pin of the pull bar the other end, and up and down or the pull bar that moves forward, then can realize the replacing or the maintaining of this mechanism smoothly.
In the using process of some machinery; In case unexpected fault occurs, the position of journal stirrup in all parts that are connected of this equipment can occur can't realizing relatively moving; Or the distance that is moved is too little, far can not reach the requirement of smooth dismounting " fault " component.Thereby brought a difficult problem for this equipment maintenance.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, reliable and practical, can be widely used under the Minepit environment, and the occasion of various compact structure equipment component designs is guaranteed novel the ear structure that the normal O&M of this equipment maintains.
The purpose of the utility model is achieved in that this mechanism comprises component such as compression casing, compacting casing, bearing pin, movable journal stirrup.Compression casing both sides are semi-enclosed box-shaped structural member; Its front end contains the grid of some identical sizes, and the rectangular sleeve structure is contained at the rear portion, at the front-end face of this sleeve; The vertical direction at grid middle part is welding fixedly journal stirrup, and the outside of this journal stirrup also is equipped with movable journal stirrup.The compacting casing is installed in the grid of compression casing, and through bearing pin and fixedly journal stirrup, movable journal stirrup link together.
Compression casing in the said mechanism; The intermediate portion of both sides (rectangular sleeve front end) is a semi-closed structure; Be positioned at the front-end face of rectangular sleeve; Contain a fixedly journal stirrup in each grid, the above-below direction that is positioned at this journal stirrup outside also is designed with two small sircle holes, leaves the circular hole of leaked substance on the base plate of each grid middle and lower part.Two pin feature are contained in the installation bottom surface of its movable journal stirrup, guarantee and the contiguous fixedly requirement of positional accuracy between the journal stirrup, and through the front-end face of screw in compression casing rectangular sleeve.
Compacting casing in the said mechanism is formed by compression cylinder, spherical hinge structure, locking pin and compacting component-assembled.This compacting casing is installed in the inside of compression casing, and the cylinder barrel of its oil cylinder rear end is a single ear structure, is installed in the movable journal stirrup and the fixing centre of journal stirrup, and is hinged on through bearing pin and compresses on the casing.Duration of work, under the effect of compression cylinder, the compacting parts can be done the fore-and-aft direction motion, with the compacting functions of realizing presetting.The compression cylinder front end is a spheric structure, links together with the compacting parts through spherical hinge structure, locking pin.The employed medium of oil cylinder is the emulsified liquid that meets the mine environmental requirement.
During installation; At first as requested compression cylinder, spherical hinge structure, locking pin are integral with the compacting component-assembled; Be placed on assembling all-in-one-piece widget in each grid of compression casing immediately, simultaneously, adjust to perpendicular attitude to the journal stirrup of compression cylinder; And keep making it to be close to fixedly on the journal stirrup, from outside look firmly fixing journal stirrup of partial occlusion sideways.Movable journal stirrup through screw on the compression casing, and guarantee and fixing position accuracy demand between the journal stirrup, accomplish compression cylinder, fixedly correct installation, the connection between journal stirrup and the movable journal stirrup through bearing pin immediately.Next, continue to accomplish hydraulic jack associated pipe, fast connection and the installation of control valve.
The advantage of the utility model; On the structure of the two journal stirrup support cylinders of integrated type; To change over dismountable movable part near the journal stirrup that the outside is installed, and the contiguous fixedly positional accuracy between the journal stirrup, the positioning dowel that increases on the dependence activity journal stirrup attachment face solves; The other end of oil cylinder has used spheric structure, guarantees under the immutable situation in its position, behind dismounting activity journal stirrup and the locking pin, can reach the purpose of moving after oil cylinder journal stirrup end can uniquely be swung also laterally, thereby realize the detachable of this oil cylinder.In extremely narrow space, rationally solve the difficult problem that the relevant device component can't normally be implemented maintaining, make to seem the thing that possibly accomplish hardly to become simple.
Be described further below in conjunction with accompanying drawing and embodiment.
