Description
Technical field
The utility model belongs to the technical field of oil cylinder installation and removal, particularly relates to a kind of swivel joint of middle bag quick changing oil cylinder.
Background technique
The major function of middle bag fast sprue-replacing system be exactly after middle water-coating port arrives life cycle online centering water-coating port change, thus substantially prolongs the working life of middle bag, reduce the consumption of middle bag refractory material, reduce expense, improve continuous casting production operation efficiency simultaneously.So the effect of stable operation in whole continuous casting production system of middle bag slide plate quick-change system seems most important.And the quick-change system of middle water-coating port has come by hydraulic jack, due to wrap in whole produce a period of time after need to change, again refractory layer is repaired, quick changing oil cylinder is wrapped in just can not being directly fixed on, quick changing oil cylinder to be pulled down before bag in replacing so each, wrap in quick changing oil cylinder is reinstalled to after in bag lifting to middle hired car in new.Quick changing oil cylinder will according in bag life cycle carry out dismantling and installing, if use permanent joint can cause, oil cylinder is easy for installation to be pulled with oil cylinder flexible pipe, can cause very to trouble to whole installation process, also joint looseness may be caused simultaneously, cause hydraulic system leakage fault, centering bag quick-change system impacts, middle bag quick-change system cisco unity malfunction.Therefore, be necessary to develop a kind of novel swivel joint, with the mounting or dismounting problem of bag quick-change system oil cylinder in effectively solving.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned Problems existing, provides a kind of swivel joint of middle bag quick changing oil cylinder, by the revolving property of swivel joint, and the operation of convenient working personnel.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of swivel joint of middle bag quick changing oil cylinder, it is characterized in that, comprise solid of rotation and fixed body, described solid of rotation is the block structure having central through bore, the bottom of solid of rotation is provided with male union, described fixed body is that one end is provided with externally threaded round column structure, one end of fixed body has tapered blind hole, the other end of fixed body is passed described central through bore and is connected with solid of rotation by stop device, one end of fixed body is abutted against by nut and solid of rotation, fixed body is provided with seal arrangement with contacting point, solid of rotation two ends, position corresponding with central through bore on fixed body has through hole, described through hole and described tapered blind hole connect.
By such scheme, described stop device comprises back-up ring and jump ring.
By such scheme, described seal arrangement is rubber seal, and described rubber seal is installed in the seal groove be provided with in described fixed body.
The beneficial effects of the utility model are: the swivel joint providing a kind of middle bag quick changing oil cylinder, under the prerequisite ensureing swivel seal, can have good flexible rotation degree, guarantee that operator can be time saving and energy saving when installing and removing operation of oil cylinde.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Wherein: 1. solid of rotation, 2. fixed body, 3. male union, 4. tapered blind hole, 5. through hole, 6. back-up ring, 7. jump ring, 8. rubber seal.
Embodiment
For understanding the utility model better, below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, a kind of swivel joint of middle bag quick changing oil cylinder, comprise solid of rotation 1 and fixed body 2, solid of rotation is the block structure having central through bore, male union 3 is provided with bottom it, fixed body is that one end is provided with externally threaded round column structure, its one end has tapered blind hole 4, the other end is passed central through bore and is connected with solid of rotation by stop device, stop device comprises back-up ring 6 and jump ring 7, jump ring is installed in the jump-ring slot be provided with in fixed body, operationally solid of rotation and fixed body two-part are thrown off to prevent swivel joint, one end of fixed body is abutted against by nut and solid of rotation, fixed body is provided with seal arrangement with contacting point, solid of rotation two ends, seal arrangement is rubber seal 8, rubber seal is installed in the seal groove be provided with in fixed body, prevent hydraulic oil liquid from leaking from swivel joint, position corresponding with central through bore on fixed body has through hole 5, through hole and tapered blind hole connect.
Swivel joint by outside thread one end of fixed body and online equipment (as oil cylinder, cylinder) be connected, male union on solid of rotation then connecting hose, online equipment is facilitated to be free to rotate and move, with the working condition requirement of satisfy the demand rotation and mobile device, energy medium enters a rotating body cavities by flexible pipe, oil cylinder or cylinder body is entered again by the through hole in fixed body and tapered blind hole, sealed by seal ring between fixed body and solid of rotation, guarantee that swivel joint does not leak, fixed body 2 is inserted in a rotating body, back-up ring and jump ring is utilized can effectively to prevent fixed body and solid of rotation from coming off when rotated.
The utility model achieves swivel joint can realize spinfunction, has also effectively stopped, because joint leaks the fault caused, to facilitate oil cylinder periodically dismantle and install, and middle bag quick-change system can normally be worked.
Claims (3)
