Description

Glass reinforced plastic hose and dilatory rope connecting device

Technical field:

The utility model relates to the connection set between glass reinforced plastic hose in the old pipeline rehabilitation work progress in the ground surface works and the dilatory rope.

Background technique:

Adopting inversion method inner lining glass fiber reinforced plastic repairing used pipeline is the comparatively convenient and economic method of constructing in the world at present.When glass reinforced plastic hose (hereinafter to be referred as flexible pipe) ploughs under in the old pipeline 1/2, flexible pipe will all enter old pipeline, at this moment, turn over lining and will make operation need to hold flexible pipe with rope according to original speed in order to continue control, so just produce flexible pipe and rope connectivity problem.Flexible pipe and rope bindiny mechanism must satisfy following 3 requirements: (1) is connected firmly, and turns in the lining process to get loose; (2) flexible pipe termination sealing must not have pressurized air to enter in the flexible pipe; (3) can pass through 90 °, 1.5D elbow smoothly.

At present in construction, the Placement between glass reinforced plastic hose and the dilatory rope be at glass reinforced plastic hose apart from termination 100mm place, laterally sever the hole that length is about 30mm in the longitudinal center of flexible pipe with cutter, will draw after rope penetrates, employing winding method is fastened.The major defect of this method is to connect firmly inadequately, and flexible pipe termination sealing is bad, finally causes entering in the flexible pipe when turning over lining hose pressurized air, and influence upset construction is carried out smoothly.Larger caliber pipeline (as φ more than 114) adopts pig's feet to link to connect and can satisfy above-mentioned requirements substantially, but φ 114 following small-bore pipelines connect because of the little employing pig's feet of aisle spare links and can't satisfy above-mentioned three requirements.

The model utility content:

In order to overcome the deficiency in the background technique, the utility model provides a kind of glass reinforced plastic hose and dilatory rope connecting device.This device is connected firmly, and turns in the lining process to get loose; The sealing of flexible pipe termination does not have pressurized air and enters in the flexible pipe; Can pass through 90 °, 1.5D elbow smoothly.

The technological scheme of employing of the present utility model is: this glass reinforced plastic hose and dilatory rope connecting device comprise conical sleeve, thin mouthful of end inner bottom surface of conical sleeve seat has plate bearing, in the annular groove of plate bearing outer wall annular ring is arranged, be installed with at least 3 pressing plates on the annular ring, pressing plate can rotate around annular ring, the taper fuse that conical sleeve inner clip plate bearing top has shape to cooperate with conical sleeve, the taper fuse is evenly distributed with groove vertically, the thin end of the degree of depth of groove is darker than butt end, pressing plate places in the groove, and careful mouthful of end of tapered core has screw rod, and screw rod passes plate bearing and conical sleeve, nut has been threaded on the screw rod, one end of nut is jagged, is connected with cross shaped joint by bearing pin in the breach, and cross shaped joint can rotate around bearing pin, the other end of cross shaped joint is connected with the bolt becket bridle by axle, and bolt rope threaded shaft can rotate.

The utlity model has following beneficial effect: after adopting such scheme, hose proof is on the taper fuse, the tube wall of flexible pipe is compressed into the groove of taper fuse by pressing plate, put conical sleeve after compressing by pressing plate, in screwing in nut pulling tapered core subprocess, because conical sleeve and taper fuse all are that the very firm of stressed joint more drawn in taper more; This linkage structure is except being connected firmly and seal relatively goodly, and pressurized air can not enter in the flexible pipe, guarantees upset everything goes well with your work to carry out; Cross shaped joint and bolt becket bridle can both rotate around bearing pin, so this device can pass through 90 °, 1.5D elbow, applied widely, application area is wide.

Description of drawings:

Fig. 1 is a sectional view of the present utility model.

1-taper fuse; 2-pressing plate; 3-plate bearing; 4-conical sleeve; 5-nut; 6-cross shaped joint; 7-bolt becket bridle; 8-axle; 9-bearing pin; 10-rope; 11-flexible pipe; The 12-annular ring.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing: this glass reinforced plastic hose and dilatory rope connecting device comprise conical sleeve 4,4 thin mouthfuls of ends of conical sleeve inner bottom surface seat has plate bearing 3, plate bearing 3 is provided with center hole, plate bearing 3 is sleeved on the bolt outside of taper fuse 1, and conical sleeve 4 also is sleeved on the bolt of taper fuse 1.In the annular groove of plate bearing 3 outer walls annular ring 12 is arranged, be installed with 6 pressing plates 2 on the annular ring 12, position corresponding with pressing plate 2 on the plate bearing 3 has radial groove and annular groove and radial groove to communicate, pressing plate 2 can rotate around annular ring 12, the taper fuse 1 that conical sleeve 4 inner clip plate bearings 3 tops have shape to cooperate with conical sleeve 4, conical sleeve 4 taperings are identical with taper fuse 1, and internal diameter is than big two thickness of soft tube of taper fuse.Taper fuse 1 left end diameter is big, the right-hand member diameter is little, arrange six rectangle grooves along branches such as axis, press the equivalent groove depth that calculates of cross-sectional profiles girth and flexible pipe girth, be that the thin end of groove depth is darker than butt end, it is that 1 thin mouthful of end of taper fuse has screw rod that taper fuse 1 right-hand member is made bolt, and six pressing plates 2 are put into six grooves of taper fuse 1 respectively.Screw rod passes plate bearing 3 and conical sleeve 4, and the nut 5 that has been threaded on the screw rod promotes conical sleeve 4 with nut 5 and by plate bearing 3 pressing plate 2 is moved to the left along the groove of taper fuse 1.The groove of fuse is put in flexible pipe 11 terminations, will be by the mutual extrusion of taper fuse 1-pressing plate 2-conical sleeve 4 and firm linking together, and sealing does not enter pressurized air and guarantees that upset carries out smoothly.One end of nut 5 is jagged, be connected with cross shaped joint 6 by bearing pin 9 in the breach, cross shaped joint 6 can rotate around bearing pin 9, and the other end of cross shaped joint 6 is connected with bolt becket bridle 7 by axle 8, bolt becket bridle 7 can rotate around axle 8, so this device can pass through 90 °, 1.5D elbow.Dilatory rope 10 is tied up on bolt becket bridle 7.So just, flexible pipe 1 and 10 firm the coupling together of dilatory rope.
