Abstract
The invention relates to an anti-rotating device for cooling pipelines. The anti-rotating device comprises at least two pipe joints (2) and locking sheets (4), the locking sheets (4) are sleeved on the pipe joints (2) and provided with oval holes (4.1) corresponding to the pipe joints (2), and the section of a portion of each pipe joint (2) matched with the corresponding oval hole (4.1) is a hollow oval section (2.1). As the oval sections of the pipe joints with metal pipelines are matched with the oval holes of the locking sheets, the locking sheets and the pipe joints form a self-locking and interlocking device after the locking sheets are sleeved on the pipe joints, internal pipelines cannot be rotated in mounting and are prevented from torsion deformation or damage, the problem of internal leakage is eliminated, and the anti-rotating device is convenient to maintain, can be mounted only by one person operating outside a box, and accordingly is convenient to mount.
Description
Technical field
The present invention relates to the cooling line anti-rotation device, main being suitable in the gear-box with a circle of spiro column pipe joint or the self-locking anti-rotation on multi-turn plate-like metal cooling-pipe road, also applicable to the self-locking anti-rotation of other similar multi-pipeline form inputs, output pipe piecing devices, belong to mechanical equipment technical field.
Background technique
Present many gear-box products adopt piping installation and the system of built-in cooling oil temperature.In gear-box assembling, when installing and fixing cooling line, especially when equipment is used the external input cooling liquid of cooling line pipeline and built-in cooling line need to change or keep in repair the time, easily the integral type pipe joint with metal tubes slightly is subjected to displacement rotation at circumferencial direction, just so that the metal tubes torsional deflection in the case, fracture or displacement grazing inner rotation part, cause conduit failure; Because cooling line is built in the casing and the bottom, dismounting and change bothers very much, brings very large economic loss.
Present locking anti-rotation device is that the lock sheet of circular port matches with the circular cross-section of pipe joint.Metal tubes stretches in the pipe joint, connects into integral type pipe joint with metal tubes by welding or other locking methods.During assembling, need a people to pin the case hex surface of the integral type pipe joint that is positioned at casing with special spanner in casing, another people is the hexagon nut of fixed cover on pipe joint outside case, and assembling is complicated.
Above-mentioned installation method mainly relies on the frictional force that the screw thread pressurization produces between frictional force, lock sheet and pipe joint surface of contact between nut and the casing to prevent the rotation that external force produces.The outer end inipple of pipe joint is installed external intake line when gearbox applications, the screwing force hexagonal screw thread retention force large or the casing outer tube joint that outreaches joint slightly has deficiency, because do not have self-locking and the interlocking of circumferencial direction, the integral type pipe joint slightly has rotation will cause built-in cooling line by torsional deflection and breakage.In addition, locking measure is not enough to overcome the Rotation of pipe joint to existing lock sheet flanging to hexagon nut.
If there is above-mentioned situation, after the oiling test run, just can find pipeline leakage, thereby bring very large economic loss.
The on-the-spot installation when using, occur pipe joint not by effectively fastening, at the outer junction plane of casing perforation oil seepage phenomena is arranged, solve also very difficult.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of and designed that processing is simple, installation, maintenance convenient and install and stop during maintenance the cooling line anti-rotation device that pipeline is reversed damage.
The object of the present invention is achieved like this:
A kind of cooling line anti-rotation device, comprise pipe joint and lock sheet, described pipe joint has two at least, lock sheet is enclosed within on the pipe joint, be characterized in: have the oval hole corresponding with pipe joint on the described lock sheet, lock sheet with the oval hole is enclosed within on the pipe joint, described each pipe joint match with the oval hole part the cross section be the oval tee section of hollow.
A kind of cooling line anti-rotation device of the present invention, during installation, metal tubes stretch into respectively in the pipe joint and with the upper end of the pipe joint formula link that is connected to one, the top of pipe joint be positioned at casing and with the contacted inner surfaces of casing.
A kind of cooling line anti-rotation device of the present invention, its lock sheet is arranged on the outer surface of casing, and the lower end of pipe joint and nut are threaded connection and are fixed on the casing.
A kind of cooling line anti-rotation device of the present invention, its nut is hexagon nut.
Compared with prior art, the invention has the beneficial effects as follows:
1. owing to cooperate with the oval hole of lock sheet with the oval tee section of the pipe joint of metal tubes, lock sheet is inserted in rear and pipe joint forms the device that can reach self-locking and interlocking, therefore when installing and the built-in pipeline of pipe joint one can not be rotated, avoided pipeline torsional deflection or damage; When 2. installing, only need a people that the integral type pipe connector is passed casing and lock sheet successively, then outside casing with the lower end nut screwing clamping of pipe joint, be fixed on the casing, and, prevent getting loose of nut with an Edge Bend of lock sheet in nut on one side, therefore easy for installation; Because only need the workman to install in the casing outside, the hexagonal end face that the original built-in spanner of pipe joint is used also can be reduced to circle, favourable minimizing processing cost.3. when the integral type pipe joint is installed the internal thread tube piece of external intake line, screwing force is larger or the outer end hexagon nut retention force of original Integral joint when not enough, because oval hole lock sheet and pipe joint have formed self-locking and the interlocking of circumferencial direction, so that the pipe joint of integral type cooling line can not rotate, stopped the problem of conduit failure, prevent oil temperature can not Cooling and Lubricator the mixed damage of oil, reduced economic loss.4. when there are Seepage and the not enough problem of pipe joint fastening nuts in the joint, outer end that cooling line occurs and pass through casing, keep in repair also simple and convenient.
