Description
Technical field
The invention belongs to utilidor technical field, particularly a kind of prefabricated direct-buried thermal insulation pipe Polyurethane inclination foaming platform.
Background technology
Prefabricated direct-buried thermal insulation pipe is by working steel tube, protect plastic tube and Ju amine Zhi foam forms outward.What domestic most manufacturers adopted is vertical injection system, i.e. insulating tube horizontal positioned and frothing head is vertically injected.This injection system requires simple to foaming platform, but foamed material vertically injects in insulating tube, first impacts on steel pipe, to insulating tube two ends, foam again, due to this technique because of resistance too great Yi cause cavity, insulating tube density unevenness particularly, intermediate density is excessive and two ends density is too low.As 80 kilograms of foamed materials of excessive filling, pipe intermediate density may surpass more than 90 kilogram, and two ends density only can reach 52 kilograms, does not reach >=and the standard-required of 60 kilograms/cubic metre.The arbitrary place of insulating tube do not reach >=and the standard-required of 60 kilograms/cubic metre is defective.Also have, adopt this technique of vertical injection, protect plastic tube outward and need punch to inject, if the not tight easily water inlet of injection orifice shutoff causes insulating tube to have quality and potential safety hazard.In order to overcome the problems referred to above, some employings big-flow high-pressure Polyurethane measuring pump, blow pressure reaches 25MPa.But this Polyurethane pump is domestic, can't produce, more seriously adopt vertical injection also to need to use grease pump, the use profit of oil pump, has a strong impact on the requisite quality of insulating tube.Prefabricated direct-buried thermal insulation pipe adopts inclination injection system, and insulating tube lies in a horizontal plane on foaming platform, during foaming by hydraulic means by foaming platform certain angle that tilts, in insulating tube upper end, inject, foamed material can directly reach pipe lower end fast.This technique can solve mass defect that above-mentioned vertical injection causes, and need on plastic tube, not beat injection orifice again, does not need to adopt 25MPa high pressure Polyurethane pump, do not need grease pump, quality and hidden danger can be effectively eliminated, without overpressure injection, foaming raw material even density again can be economized.As D1420/D1600 insulating tube, environment temperature 11 degree, enjoys foamed material advanced in years, and during 82 kilograms of/cubic metre of of excessive charging quantities, two ends density reaches 68 kilograms, and during 78 kilograms of/cubic metre of of excessive charging quantities, two ends density reaches 63 kilograms.Existing enterprise is used inclination foaming platform, but what have is constant tilt, and effect is not ideal enough; What have is end hinge dress, and rising or falling speed is slow, uses inconvenient; Existing foaming platform cannot be satisfied the demand, needs a kind of inclination foaming platform easy and simple to handle, easy to use badly.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of easy and simple to handle, easy to use, can improve filling speed, improve the quality of products, eliminate the prefabricated direct-buried thermal insulation pipe Polyurethane inclination foaming platform of quality and potential safety hazard.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of prefabricated direct-buried thermal insulation pipe Polyurethane inclination foaming platform, comprise large support, platform in pipe, parallel propulsion device, it is characterized in that: also comprise tilting gearing, parallel propulsion device symmetry is installed in large support both ends, and the symmetry of platform in pipe is installed in end face on large support, large support rotates and is installed on tilting gearing, described tilting gearing, is comprised of bearing, dump ram, and bearing is installed in subsurface, dump ram lower end hinge is loaded on ground, upper end and large support hinge dress.
And, described large support, its center is shaped with backbar, and backbar is solidly installed with large support.
And, described backbar, its two ends are shaped with spindle nose.
And, described bearing, its top is shaped with axle bed.
Advantage of the present invention and beneficial effect are:
Prefabricated direct-buried thermal insulation pipe Polyurethane inclination foaming platform of the present invention is provided with tilting gearing, can implement injection to insulating tube, thereby can improve injection speed, improve the quality of products, tilting gearing adopts oil cylinder lifting to tilt, easy and simple to handle, easy to use, be a kind of prefabricated direct-buried thermal insulation pipe Polyurethane inclination foaming platform with higher innovation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1-parallel propulsion device, 2-dump ram, 3-backbar, 4-spindle nose, 5-axle bed, 6-bearing, 7-platform in pipe, the large support of 8-.
The specific embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A prefabricated direct-buried thermal insulation pipe Polyurethane inclination foaming platform, comprises large support 8, platform in pipe 7, parallel propulsion device 1, and its innovation is: also comprise tilting gearing.Parallel propulsion device is two groups, and symmetry is installed in large support both ends; Two parts in Guan Taiwei, symmetry is installed in end face on large support; Large support, its center is shaped with backbar 3, and backbar is solidly installed with large support, backbar, its two ends are shaped with spindle nose 4, and large support is installed on tilting gearing by the spindle nose rotation at backbar two ends.Tilting gearing, is comprised of bearing 6, dump ram 2, and bearing is installed in subsurface, and bearing top is shaped with axle bed 5, for spindle nose is installed.Dump ram lower end hinge is loaded on subsurface, upper end and the anterior hinge dress of large support.
Operation principle of the present invention is:
While utilizing prefabricated direct-buried thermal insulation pipe Polyurethane inclination foaming platform of the present invention to carry out polyurethane injection to insulating tube, first insulating tube to be injected is lain in a horizontal plane on platform in pipe, the parallel propulsion device that starts two ends is tight by the shutoff of insulating tube two ends, restart dump ram, dump ram promotes large support and rotates on bearing, large support is anterior upwards to rise, and lands downwards in rear portion, thereby the insulating tube on large support, platform in pipe and platform in pipe is inclined; After insulating tube is inclined, from insulating tube upper end, inject, polyurethane flows to lower end with fast speed, when being expelled to when a certain amount of, loosen dump ram, make large support, platform in pipe and insulating tube revert to level, polyurethane automatic back flow balance in insulating tube, after foamed set, polyurethane density equalization in insulating tube, product percent of pass improves greatly.
Although disclose for the purpose of illustration embodiments of the invention and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the present invention and claims, various replacements, variation and modification are all possible, therefore, scope of the present invention is not limited to embodiment and the disclosed content of accompanying drawing.
