Abstract
The invention relates to a detachable lug structure used for ensuring the smooth daily maintenance of vulnerable parts of various extremely-compact mechanical devices in a narrow space in a mine environment. The structure comprises a compression casing, a compacting casing, pins, movable lugs and the like, wherein the compacting casing is arranged in the compression casing, and the cylinder at the rear end of the oil cylinder of the compacting casing has a single-lug structure, is arranged between the movable lug and the fixed lug, and is hinged to the compression casing through the pins; the outside lug in the whole dual-lug support oil cylinder structure is changed to a detachable movable part, and the precision of a distance from the detachable movable part to the fixed lug is solved depended on the positioning pins arranged on the installation surface of the movable lug; and the other end of the oil cylinder uses a spherical structure to ensure the realization of the swing of the lug end of the oil cylinder and the backward movement of the lug end after detaching the movable lug and locking the pins without changing the position of the oil cylinder, so the dismounting operation of the parts of the oil cylinder is ensured.
Description
Technical field
The present invention 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 this invention is to provide a kind of simple in structurely, reliable and practical, can be widely used under the Minepit environment, the occasion of various compact structure equipment components designs is guaranteed the detachable ear structure of the normal O&M maintenance of this equipment.
The objective of the invention is to realize like this: 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; Outer side surface also has short cover and borehole structure; Guarantee and close on the fixedly requirement of positional accuracy between the journal stirrup, and to fixing need of bearing pin, and through screw at the front-end face that compresses the 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.
Advantage of the present invention; 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.
Description of drawings
Fig. 1 is one embodiment of the present of invention structural drawing.
Fig. 2 is to view among Fig. 1.
Fig. 3 is a sectional view among Fig. 1.
Embodiment
Be installed in compacting casing (4) as requested in the grid of compression casing (5) front-end face, the journal stirrup of adjustment oil cylinder rear end cylinder barrel is in perpendicular attitude, and journal stirrup fits to keep inboard face of this journal stirrup and compression casing (5) to go up fixedly; With the pin that expose movable journal stirrup (3) bottom plane, insert compression casing (5) and go up in the corresponding hole, and the two corresponding journal stirrup same size circular holes that guarantee to be close with one heart, mounting screw (1) is also tightened it by the screw-down torque of regulation; Suitably raise the journal stirrup of compacting casing (4) rear portion oil cylinder then, guarantee this journal stirrup with above-mentioned movable journal stirrup, fixedly journal stirrup corresponding circle hole is concentric, insert bearing pin (2).
