Description

Crane oil inlet pipe more changing device
Technical field
The invention belongs to maintenance of equipment fields, and in particular to crane oil inlet pipe more changing device.
Background technique
Oil inlet pipe is common oil transport pipeline in the hydraulic system of crane, but is also most to be also easy to produce to let out in hydraulic system The position of leakage, wherein common oil inlet pipe is the generally firm, sealing using connection when the connection of other pipelines in hydraulic system The good ferrule-type compression joint of performance is attached.
As described in Figure 1, ferrule-type compression joint is made of fitting body 1, cutting ferrule 2 and clamp nut 3 with bellmouth, is compressed The threaded connection of nut 3 and 1 left end of fitting body is realized the connection of oil inlet pipe 4 and fitting body 1;Then the spiral shell of 1 right end of fitting body Line is threadedly coupled with the connector 5 in hydraulic system, is realized the connection of oil inlet pipe 4 and hydraulic system.
When leakage occurring in oil inlet pipe 4, sealing is not tight the problems such as, fixed connector 5 is needed, swivel body 1 allows connector Body 1 is kept completely separate with connector 5, and the fixation of connector 5 sometimes does not cause tightly fitting body 1 to be difficult to screw out, and reduces the replacement of oil inlet pipe 4 Efficiency;When butt joint body 1 is selected, detent is generally carried out using spanner butt joint body 1 and is produced, due to using mutual disassembly Mode, so the rotation angle of spanner is limited, fitting body 1 could be screwed out by needing multiple butt joint body 1 to carry out detent, meeting The replacement efficiency of strong influence oil inlet pipe.
Summary of the invention
The invention is intended to provide crane oil inlet pipe more changing device, quickly to be replaced to oil inlet pipe.
In order to achieve the above object, base case of the invention is as follows: crane oil inlet pipe more changing device, including support Frame, further includes power mechanism and mechanism for assembling-disassembling, and the power mechanism includes motor, stud, screw rod and stud is driven to rotate Driving gear, the stud are coaxially mounted on screw rod, and screw stem water is flat to be slidably mounted on support frame, driving gear and motor Power output end be fixedly connected;The mechanism for assembling-disassembling includes that several spring levers, the first fixed block of semi-annular shape and second are solid Determine the first rotating block and the second rotating block of block and semi-annular shape, the radius phase of first fixed block and the second fixed block Together, the radius of the first rotating block and the second rotating block is identical, and one end of the first fixed block and one end of the second fixed block buckle Connection, the other end of the first fixed block and the other end of the second fixed block snap connection, one end of the first rotating block and second turn One end of motion block connects, the other end connection of the other end of the first rotating block and the second rotating block, the side of first fixed block Face is equipped with first annular slot, and the second fixed block is equipped with the second annular groove being connected to first annular slot, the first rotating block Side is equipped with third annular groove, and the side of the second rotating block is equipped with the fourth annular slot being connected to third annular groove, described First fixed block, the second fixed block, the first rotating block and the second rotating block are coaxially disposed;The spring lever is horizontally disposed, bullet One end of spring base and the inner wall of first annular slot or the second annular groove are slidably connected, the other end of spring lever and third annular groove or The inner wall of fourth annular slot is slidably connected;First rotating block and the second rotating block outer wall are equipped with the transmission engaged with stud Tooth.
The principle of base case: when needing to dismantle oil inlet pipe, by the first fixed block and the second fixed block both ends point It is not fastened togather, and the first fixed block and the second fixed block is allowed to be fixed on connector position, at this time the first rotating block and second turn Motion block is also fastened on together, and fasten after the first rotating block and the second rotating block be located at fitting body, spring lever be in press Contracting state;Be then turned on motor, motor drives driving gear to rotate forward, and driving gear drives stud rotation, stud with Transmission tooth engagement on first rotating block and the second rotating block drives the first rotating block and the rotation of the second rotating block, and then first Rotating block and the second rotating block drive fitting body to go out to screw out from connector, and spring lever is stretched during this, when fitting body is complete Wheel goes out the disassembly completed to flowline.
