Description
Technical field
The utility model relates to a kind of equipment for liquid transportation, and a kind of hydraulic pressure that connects High Pressure Gun of more specifically saying so is carried and connected rot.
Background technique
At present being connected between the long-range inject high pressure rifle that uses on waterwheel, the fire-fighting truck and the outlet pipe is the sleeve pipe that adopts the band seal ring basically, because High Pressure Gun directly is pressed on the seal ring, when in use rotating High Pressure Gun toward true dip direction, the unbalance stress of seal ring, cause wearing and tearing easily, working life is short, also occurs water leakage phenomenon easily, and build-up of pressure descends, range reduces, and orientation is bad when rotating, and rotational resistance is big, and labor intensity is big.
The China Patent No. 200720081691.8 of this case claimant invention, the technological scheme of model utility title " a kind of liquid conveying slewing gear " can well solve the problem of above-mentioned existence, this device is by hollow shaft and is installed in fixed base on the hollow shaft, parts such as rotary sleeve and connecting sleeve constitute, connecting sleeve is connected with High Pressure Gun, fixed base is connected with outlet pipe, between rotary sleeve and the hollow shaft bearing is housed, sealing between connecting sleeve and the hollow shaft is by an oil sealing sleeve is installed, and load onto in the oil sealing sleeve that oil sealing seals, this sealing configuration is relatively more assorted multiple, make that the processing cost of whole slewing gear is higher, and fixed base necessarily requires hollow shaft to equate with the internal diameter of outlet pipe when joining with outlet pipe, and two nut dismounting that are installed in simultaneously in the fixed base are all inconvenient.
The model utility content
Technical problem to be solved in the utility model provide a kind of simple in structure, cost is low, and the hydraulic pressure of easy accessibility carry to connect rot.
The utility model solves the problems of the technologies described above with following technological scheme: hydraulic pressure of the present utility model carries the connection rot to include the hollow shaft 14 that is installed between outlet pipe and the High Pressure Gun, hollow shaft 14 is equipped with fixed base 7 from the bottom to top successively, rotary sleeve 4 and connecting sleeve 1, connecting sleeve one end is connected with High Pressure Gun, the other end is connected with rotary sleeve, two nuts are up and down arranged in the lower cavity of fixed base, be between nut and the fixed base 7 between upper cap nut and the hollow shaft 14 and down and be threaded, the bottom of rotary sleeve 4 is enclosed within on the top cylinder of fixed base 7, there is the bearing 6 that is installed on the hollow shaft 14 its inside, hollow shaft 14 is provided with the bulge loop 5 that is positioned at the bearing top, in the cavity between connecting sleeve 1 and the hollow shaft 14 oil sealing 3 is installed.
Two nuts up and down in described fixed base 7 lower cavity all have mounting hole, and the bottom of upper cap nut and the bottom of hollow shaft maintain an equal level, and between two nuts seal washer are installed.
The interior upper wall of described hollow shaft 14 can be provided with at least one projection 15.
Hydraulic pressure of the present utility model is carried and is connected the rotation of rot employing bearing, can reduce rotational resistance, reduce labor intensity, make in pressurized operation, rotate freely convenient, and, can reduce the processing cost of this rot greatly, and the dismounting nut is more convenient owing to prevent that the seal configuration of leak of liquid is fairly simple.
Description of drawings
Fig. 1 is that the utility model hydraulic pressure is carried the structural representation that connects rot.
Embodiment
As shown in Figure 1, the hollow shaft 14 that is installed between outlet pipe and the High Pressure Gun is equipped with fixed base 7, rotary sleeve 4 and connecting sleeve 1 from the bottom to top successively, one end of connecting sleeve 1 is connected with High Pressure Gun, the other end is connected by bolt 2 with rotary sleeve 4, the bottom of rotary sleeve 4 is enclosed within on the top cylinder of fixed base 7, there is the bearing 6 that is installed on the hollow shaft 14 its inside, and hollow shaft 14 is provided with the bulge loop 5 that is positioned at the bearing top, in the cavity between connecting sleeve 1 and the hollow shaft 14 oil sealing 3 is installed; The installation screw of using when being connected with outlet pipe 8 is arranged on the fixed base 7, upper cap nut 9 and following nut 11 are arranged in the cavity of its underpart, be between nut 11 and the fixed base 7 between upper cap nut 9 and the hollow shaft 14 and down and be threaded, the lower end of upper cap nut 9 has the mounting hole 13 of being convenient to lock nut, the lower end of following nut 11 has the mounting hole 10 of being convenient to lock nut, the bottom of the bottom of hollow shaft 14 and upper cap nut 9 maintains an equal level, and between two nuts seal washer 12 is installed up and down; The interior upper wall of hollow shaft 14 is provided with two projectioies 15, so that position when installing and fixing two nuts of a bottom.
During installation, elder generation's tightening nuts 9, fixed base 7 and bearing 6 are fixed on the hollow shaft 14 by bulge loop 5 and nut 9, and then tightening nuts 11, fixed base 7 and outlet pipe are connected through screw 8 usefulness bolts are installed again, and tighten the bolt 2 that connects between rotary sleeve 4 and the connecting sleeve 1, the top of connecting sleeve 1 is connected with High Pressure Gun, install back liquid and enter High Pressure Gun through hollow shaft 14, can spray from the outlet pipe outflow.Rotation High Pressure Gun during use, connecting sleeve 1 and oil sealing 3 also rotate thereupon, and driven rotary cover 4 rotates, because bearing in the rotary sleeve and hollow shaft friction are very little, therefore, the resistance of rotation High Pressure Gun will reduce, labor intensity is low, and is easy to use, and the oil sealing that is installed in hollow shaft top only seals, need not bear the supporting role of other parts, therefore be difficult for being damaged, long service life, and also the utility model is simple in structure, processing cost is low, is convenient to extensively promote the use of.
Because the nut in fixed base 7 lower cavity is equipped with mounting hole, be convenient to installation and removal operation of the present utility model, and the bottom of the bottom of hollow shaft 14 and upper cap nut 9 is fair, and therefore the diameter of outflow tube that is connected with hollow shaft also can be unequal with the hollow shaft internal diameter.
Rot of the present utility model also applicable to Jia Shui such as water conservancy, waterwheel, oily car, fire-fighting, harbour, station, oil conveyance conduit on, use very extensive.
