Abstract
The utility model relates to a double-end safety guarantee high-pressure oil ejection structure. An outer hexagonal oil pipe connector is screwed to a bearing seat, and an inner hexagonal locking plate covers the outer hexagonal oil pipe connector and then is fixed by a screw, so that the effect of locking the oil pipe connector and the bearing seat is realized, and a sealing failure due to the twisting of an outer structure after an inner structure is mounted is avoided; and a safety guarantee lock head is screwed at a thread part of the head of a check valve and the bottom of the lock head props against a spring clamping sheet of the check valve, so that the safety guarantee effect is realized and the risk that a spring is accidentally popped out is avoided. The double-end safety guarantee high-pressure oil ejection structure has the characteristics of simple and compact structure, convenience for installation, good sealing effect and the like.
Description
Technical field
The utility model relates to a kind of sliding bearing high pressure oil jacking device structure, especially a kind of double end safety guarantee high pressure oil jacking device.
Background technique
Sliding bearing alternately or under the operating mode of high capacity, generally adopts high pressure oil jacking device in frequent clockwise and anticlockwise at present.Adopt high pressure oil jacking to be set effective to have alleviated that oil film does not form the excessive problem of friction factor when motor is initial, still can provide enough lubricant oil to provide safeguard when also stopping transport for electrical fault, assurance bearing, motor safety.In this simultaneously, also there are this some problems in high pressure oil jacking device, affects the installation, maintenance of high pressure oil jacking device.Concrete manifestation is as follows: the one-way valve structures that traditional high-pressure jacking device adopts is fragile, and contained spring has the possibility that breaks away from body; The high-pressure oil pipe good airproof performance should be closing compactness during sealing, if but bear turning round of external force draw after very easily seal failure, this causes difficulty for installation, maintenance high pressure oil top.
Summary of the invention
The purpose of this utility model is to design the double end safety guarantee high pressure oil jacking device of a kind of replacement simple and compact for structure, easy for installation, easy, maintenance economy according to the drawback of existing structure.The technical solution of the utility model is so to realize:
A kind of double end safety guarantee high pressure oil roof construction, comprise oil connection, high pressure hose, the hollow bolt of being located at oil pipe one end and the high pressure joint of being located at the oil pipe the other end, with the one-way valve of spring card, cover has locking plate on the oil connection, described locking plate is fixed on the required bearing support by screw, and the spring card top in the described one-way valve is provided with a safety lock head.
As preferably, described oil connection is the outer-hexagonal oil connection, and locking plate is interior hexagonal locking plate.
As preferably, be provided with packing ring between described locking plate and the bearing support.
The double end safety guarantee high pressure oil roof construction of the utility model design, that the outer-hexagonal oil connection is screwed to bearing support, entangle the outer-hexagonal oil connection with interior hexagonal locking plate again, be screwed interior hexagonal locking plate, so just realized the effect with oil connection and bearing support " locking ", drawn and cause seal failure with turning round of external structure after having avoided internal structure to install; The safety guarantee tapered end of screwing at one-way valve head threads place, the spring card place that one-way valve is withstood in the tapered end bottom has so just realized the safety guarantee effect, has avoided the unexpected risk that ejects of spring.The utlity model has the characteristics such as simple and compact for structure, easy for installation, good sealing effect.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the technical solution of the utility model is described in further detail.
Embodiment: with reference to the accompanying drawings, a kind of double end safety guarantee high pressure oil roof construction, comprise outer-hexagonal oil connection 3, high pressure hose 4, the hollow bolt 6 of being located at oil pipe 13 1 ends and the high pressure joint 8 of being located at oil pipe 13 the other ends, with the one-way valve 9 of spring card, cover has interior hexagonal locking plate 1 on the oil connection 3, described locking plate 1 is fixed on the required bearing support 11 by screw 7, be provided with packing ring 2 between described locking plate 1 and the bearing support 11, spring card 12 tops in the described one-way valve 9 are provided with a safety lock head 10.
During installation outer-hexagonal oil connection 3 is screwed to bearing support 11, entangle outer-hexagonal oil connection 3 with interior hexagonal locking plate 1 again, with screw 7 fixing interior hexagonal locking plates 1, so just realized oil connection 3 effect with bearing support 11 " locking ", avoided internal structure to install drawing with turning round of external structure afterwards and cause seal failure; The safety lock head 10 of screwing at one-way valve 9 head threads places, spring card 12 places that one-way valve 9 is withstood in safety lock head 10 bottoms have so just realized the safety guarantee effect, have avoided the unexpected risk that ejects of spring.
