Abstract
The utility model relates to a pressure injection device of bridge cable corrosion inhibitor, which comprises a pressure injection machine, a high pressure soft pipe and a sealing fixture, and a discharge hole of the pressure injection machine and a glue injection port of the sealing fixture are connected through the high pressure soft pipe.
Description
Technical field
The utility model relates to the pressure injection device of bridge cable body corrosion inhibitor.
Background technology
Suspension bridge and cable-stayed bridge etc. are to use more long-span bridge girder construction at present, and the bridge cable system is the major bearing structures of suspension bridge and cable-stayed bridge etc., is the life rope of bridge.In case funicular system corrodes, consequence is with hardly imaginable.In order to ensure the structure of bridge, must protect cable.The main push-towing rope protection of suspension bridge has formed comparatively mature technique, and is used widely.But the resist technology of the hoist cable structure in the hoist cable structure of the cable body of suspension bridge and cable-stayed bridge, particularly suspension bridge and the anchor cup also is not very perfect.
At present the safeguard procedures that the cable-stayed bridge cable body is adopted have twine the special use band that is wrapped outside former PE layers, as rubber strip or plastic tape, form new protective layer; Perhaps adopt double-deck PE layering extrusion molding, limit outer crackle and expand to nexine.And the hoist cable cable body of suspension bridge adopts the protection of paint coatings system usually.
Existing measure has been played certain effect for prolonging the cable body protection life-span; but because above-mentioned technology can only be carried out face seal to cable body; and the steel strand wires in the cable body exist slight gap; according to capillary principle; rainwater and Korrosionsmedium are inhaled in the slit between the steel strand wires, impel the cable body corrosion.
In addition, rainwater and steel strand wires are owing to the effect of gravity, and the anchor cup position along twisted wire arrival cable body bottom causes the anchor cup to be in dampness for a long time, and moisture, air and the Korrosionsmedium of anchor cup cable body inside can't be discharged.Therefore, the steel strand wires of this position cable body very easily corrode.Owing to above reason, the protection of anchor cup position cable body is the position of the easiest generation corrosion failure of suspension bridge cable body structure, also is the industry problem to be solved of having to go to the toilet.
Disclose a kind of full seal type drag-line among the CN2725343Y, the hawser outer surface has been coated overcoat, the outer surface of individual wire and the gap between individual wire and the individual wire evenly have been coated with the preserving and sealing layer.But it is the unexposed preserving and sealing layer that how to apply also.Any equipment or the device that can realize the preserving and sealing effect do not disclosed in the prior art yet.
Summary of the invention
The purpose of this utility model is to provide a kind of pressure injection device of bridge cable body corrosion inhibitor, really realizes the preserving and sealing effect of cable body.
The utility model is achieved through the following technical solutions:
A kind of pressure injection device of bridge cable body corrosion inhibitor comprises pressure feeding machine, high-pressure hose and sealing clamp, wherein is connected with the gum-injecting port of sealing clamp by the discharging opening of high-pressure hose with the pressure feeding machine; Described pressure feeding machine comprises entablature, piston, moulding cylinder, discharging opening, hydraulic cylinder, trave lling girder, column, cylinder plunger and base, wherein entablature is connected by two heel posts with base, and the trave lling girder both sides are socketed on the column of the left and right sides, thereby guarantee and can move up and down on column by trave lling girder; The upper end of piston is fixed on the bottom of entablature, and the moulding cylinder is fixed on the top of trave lling girder, and hydraulic cylinder is fixed on base top by the chassis.
Wherein said hydraulic cylinder can be exerted pressure by mechanically actuated or manual operations.Mechanically actuated can be controlled by program by linking to each other with computer, and manual operations then can realize by manual pressure by establishing the one handle (not shown) in the hydraulic cylinder outside.
Described high-pressure hose is preferably the plastics high-pressure hose, and its two ends can be connected with two logical or threeways, to realize and being connected of pressure feeding machine and sealing clamp that its connected mode also is a connected mode known in the field, connects as bolt.
Wherein said sealing clamp comprises gum-injecting port, hinge and bolt.Anchor clamps can be provided with the material of sealing clamp at the gum-injecting port place and be advisable with steel, and hinge can be in the relative both sides of anchor clamps with bolt.Open hinge, anchor clamps are enclosed within on the cable wire, the hinge that closes then cuts out anchor clamps by bolt.
Wherein said discharging opening and gum-injecting port can be for one or more, and preferred 1-4, more preferably 1-3, most preferably 1-2.
In a preferred embodiment of the invention, all fixed forms are that bolt connects or riveted joint, and more preferably bolt connects.
For the sealing protection method in the cable body, can realize by sealing clamp, in plastics Glass cement squeezing device that the fluid sealant for preparing is packed into, load onto obstruction then, put into the pressure injection rifle, and with the gum-injecting port of pressure injection rifle line-up jig, the turn helix tube, thus the gum-injecting port of fluid sealant by anchor clamps injected in the cable body.
And, then realize jointly by pressure feeding machine, high-pressure hose and sealing clamp for the sealing protection method of cable body outside.
Description of drawings
Fig. 1 is the schematic diagram of pressure feeding machine.
Fig. 2 a, 2b are the sectional view of sealing clamp.
Wherein related Reference numeral is as follows in the accompanying drawing:
1, entablature 2, piston 3, moulding cylinder 4, discharging opening 5, hydraulic cylinder 6, trave lling girder 7, column 8, base 9, cylinder plunger 10, the steel strand wires hoist cable 11 for the treatment of injecting glue, sealing clamp 12, gum-injecting port 13, hinge 14, bolt
The specific embodiment
Be elaborated with reference to the accompanying drawings.
The hinge of the sealing clamp of steel is opened, and anchor clamps are enclosed within on the cable body of hoist cable, the hinge that closes then cuts out anchor clamps by bolt.Plastics high-pressure hose one end is connected with the gum-injecting port of sealing clamp, and the other end is connected with the discharging opening of pressure feeding machine.Start the pressure feeding machine, to place in the moulding cylinder as low viscosity non-drying materials such as 9501D sealing compounds, manually injecting glue, slowly exerted pressure 5 minutes, pressurize 30～60 minutes, the water that cable body contains in former anchor cup flows out from anchor cup bottom, illustrates that glue fills with, then anchor clamps are taken off, carry out other treatment process, as tear sealing clamp open, and the low viscosity non-drying material at the cable body outer surface is exposed in cleaning; The brushing fluid sealant fills up this this section of section cable body groove, twines glass cloth and last hypomere overlap joint, with rare brush coating shaping; Construction section cable body external coating fluid sealant is carried out whole shaping, wait to solidify the clean surface, back; Treat brushing finish paint behind the described fluid sealant natural vulcanization.
