Abstract
The utility model discloses a filling device for the reinforcing sleeve of a steel pipe. The reinforcing sleeve is a cylindrical sleeve composed of two closed and fixedly-connected two parts, namely, an upper cambered sleeve and a lower cambered sleeve; the reinforcing sleeve is sleeved on the steel pipe to be reinforced and a circular space clearance is left between the reinforcing sleeve and the steel pipe; a filling device filled with resin is connected to the injection port of the reinforcing sleeve and used for filling the resin into the space clearance; a vacuum pump is arranged at the air outlet of the reinforcing sleeve and used for pumping to ensure the resin to be filled in a vacuum condition, thereby air bladders in the resin in the circular space are eliminated or reduced and the reinforcing sleeve is ensured to play the sealing and bearing roles for the reinforced steel pipe.
Description
Technical field
The utility model relates to a kind of reinforcement sleeve device for casting of steel pipe, especially can eliminate or reduce the reinforcement sleeve device for casting of the steel pipe that has bubble in the filling resin material.
Background technology
At present, the reinforcement sleeve device for casting of known steel pipe, the reenforcing sleeve jacket casing is contained in by on the reinforcement steel pipe, and leave annular space between the two, the reinforcement sleeve by last arc sleeve and arc lower sleeve closed fixed be tubular construction, have on the reinforcement sleeve to be no less than each one inlet and exhaust outlet that connects with annular space, by injecting tube connector connection inlet, injection valve, injection container are installed in proper order, and the exhaust outlet on the reinforcement sleeve communicates with atmosphere.When the resin perfusion of carrying out the reinforcement sleeve, be contained in the resin material that injects in the container, under the flow by gravity effect by injecting that tube connector flows through in regular turn that injection valve, inlet on the reinforcement sleeve flows into the reinforcement sleeve and by the annular space between the reinforcement steel pipe, resin material is extruded exhaust outlet with gas in the annular space, after filling up annular space, resin material closes injection valve, make the reinforcement sleeve after the resin material spontaneous curing and by bonding mutually between the reinforcement steel pipe, make the reinforcement sleeve play sealing and share the effect of pressing in the steel pipe of bearing.But, the gas that the resin material that pours into annular space owing to flow by gravity is difficult to extrude fully in the annular space forms bubble, the perhaps former gas that dissolves in the resin material disengages gas and forms bubble under the curing reaction heat effect, thereby has reduced the reinforcement sleeve to by the sealing function of reinforcement steel pipe and pressure-bearing effect.
Summary of the invention
In order to overcome the unclean deficiency of reinforcement sleeve device for casting bubble row of existing steel pipe, the utility model provides a kind of reinforcement sleeve device for casting of steel pipe, this device for casting not only can be when resin material injects annular space can the emptying bubble, the bubble that can also eliminate or reduce resin material to disengage gas under the curing reaction heat effect and form guarantees that the reinforcement sleeve installed is to by the sealing of reinforcement steel pipe and pressure-bearing effect.
The technical scheme that the utility model technical solution problem is adopted is: the reenforcing sleeve jacket casing of tubular is contained in by on the reinforcement steel pipe, and leave annular space between the two, the reinforcement sleeve fixedly constitutes by last arc sleeve and arc lower sleeve are closed, have on the reinforcement sleeve and be no less than each one inlet and exhaust outlet that connects with annular space, by injecting tube connector the connection inlet is installed in proper order, injection valve, inject container, tube connector is installed the connection exhaust outlet in proper order by bleeding, suction valve, vavuum pump, simultaneously for guaranteeing the sealing of annular space, in the closed faying face of last arc sleeve and arc lower sleeve both sides, strip lateral seal part is installed all, carries out end face seal at the reinforcement sleeve and by the axial two ends installation of the annular space between reinforcement steel pipe annular seal.
When the resin material in injecting container injects annular space, the guiding resin material was got rid of gas and is full of the full annular space when vavuum pump running was found time to annular space, close injection valve, vavuum pump remains in operation and finds time, after the gas of waiting to dissolve in resin material overflows and is drawn out of, close suction valve, wait for that the resin material spontaneous curing is not after have a flowability, remove tube connector and the jockey installed on inlet and the exhaust outlet, reach the purpose of eliminating or reducing bubble in the annular space.
The beneficial effects of the utility model are, adopt the method for vacuum draw decompression to carry out the perfusion of resin material, the adhering resin layer that poured in the annular space between reinforcement steel pipe and reinforcement sleeve is eliminated or reduced bubble, guarantee that the reinforcement sleeve installed is to by the sealing of reinforcement steel pipe and pressure-bearing effect.
