Abstract

The invention provides a hole plugging device for a cable conduit, and aims to solve the problem that the cable conduit of which the hole is plugged with plugging mud/ concrete is unlikely to dismount in the prior art. The hole plugging device comprises a sleeve, a rubber ring, a stop block, a pressing block and an extrusion device, wherein the sleeve is sleeved on a cable, the stop block is fixedly connected to one end of the sleeve, the pressing block is arranged on the sleeve and can move along the axial direction of the sleeve, the rubber ring is sleeved on the sleeve and positioned between the stop block and the pressing block, and the rubber ring is provided with a closed inner cavity which is filled with fluid; one end of the sleeve is connected with a rubber tube, and the stop block and the rubber tube are respectively positioned at two ends of the sleeve. The pressing block and the sleeve extrude the rubber ring, so that the rubber ring is diffused towards the circumference to fill the clearance between the sleeve and the cable conduit, and the sleeve and the cable can be sealed by the rubber tube; the hole plugging device has a good sealing effect and is convenient to dismount; and the axial movement of the cable due to expansion with heat and contraction with cold or other reasons does not influence sealing.

Description

A kind of pipe orifice plugging device of cable duct
Technical field
The present invention relates to a kind of pipe orifice plugging device of cable duct.
Background technology
Be inserted into cable duct at cable or need shutoff, existing shutoff adopts shutoff mud/concrete to carry out shutoff substantially, shutoff mud plugging construction is inconvenient, and cost is high, and concrete shutoff can exist certain defect and hidden danger to construction in later period/maintenance because of reasons such as the concrete blocks that produces; And be not easy dismounting, in unloading process, easily damage cable; Cable is because to expand with heat and contract with cold or other reason causes moves axially and can produce infringement to cable.
Summary of the invention
The invention provides a kind of pipe orifice plugging device of cable duct, be intended to adopt shutoff mud/concrete to carry out the pore of shutoff cable duct in solution prior art, do not allow easy-to-dismount problem.
In order to solve above technical problem, the present invention is achieved through the following technical solutions: a kind of pipe orifice plugging device of cable duct, comprise sleeve pipe, rubber ring, block, briquetting, for promoting the pressurizing unit of briquetting, casing pipe sleeve is connected on cable, described block is connected in one end of sleeve pipe, briquetting to be arranged on sleeve pipe and can moving axially along sleeve pipe, described rubber ring sleeve is connected on sleeve pipe, rubber ring is between block and briquetting, rubber ring is provided with closed inner chamber, is filled with fluid in the inner chamber of rubber ring; One end of described sleeve pipe is connected with rubber tube, and block and rubber tube lay respectively at sleeve pipe two ends.
Further, described inner chamber with rubber ring coaxial and be annular.
Further, described rubber tube is larger the closer to the position diameter of sleeve pipe; Be convenient to rubber tube and hold cable tightly, strengthen sealing property.
Further, described pressurizing unit is screwed pipe, and described outside of sleeve wall is provided with the screw thread matched with screwed pipe, and described briquetting is socketed on sleeve pipe, and described briquetting is between screwed pipe and rubber ring; Be convenient to the position of fixation clip.
Further, described screwed pipe lateral wall is provided with rotary handle; Be convenient to manual adjustments screwed pipe.
Further, water is filled with in the inner chamber of rubber ring; Cost is low, is convenient to the effect strengthening seal with elastometic washer pipeline.
Compared with prior art advantage of the present invention is: be provided with in the present invention by briquetting and sleeve pipe extruding rubber ring, makes rubber ring to circumference diffusion thus will fill the gap of full sleeve pipe and cable duct, can by sleeve pipe and cable seal by rubber tube; Good sealing effect, is convenient to dismounting, and cable is because to expand with heat and contract with cold or other reason causes moves axially, and there is not impact to sealing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is structural representation of the present invention before rubber ring compression;
Fig. 2 is structural representation of the present invention after rubber ring compression.
Embodiment
Consult Fig. 1 and Fig. 2, a kind of pipe orifice plugging device of cable duct, comprise sleeve pipe 1, rubber ring 2, block 3, briquetting 4, for promoting the pressurizing unit of briquetting 4, sleeve pipe 1 is socketed on cable, described block 3 is connected in one end of sleeve pipe 1, briquetting 4 to be arranged on sleeve pipe 1 and can moving axially along sleeve pipe 1, described rubber ring 2 is socketed on sleeve pipe 1, rubber ring 2 is between block 3 and briquetting 4, rubber ring 2 is provided with closed inner chamber, described inner chamber with rubber ring 2 coaxial and be annular, be filled with fluid in the inner chamber of rubber ring 2; One end of described sleeve pipe 1 is connected with rubber tube 5, and block 3 and rubber tube 5 lay respectively at sleeve pipe 1 two ends.Described rubber tube 5 is larger the closer to the position diameter of sleeve pipe 1.Described pressurizing unit is screwed pipe 6, and described sleeve pipe 1 lateral wall is provided with the screw thread matched with screwed pipe 6, and described briquetting 4 is socketed on sleeve pipe 1, and described briquetting 4 is between screwed pipe 6 and rubber ring 2.Described screwed pipe 6 lateral wall is provided with rotary handle 7.Water, air or other fluid is filled with in the inner chamber of rubber ring 2.
During use, rubber tube 5 is translated on sleeve pipe 1, cable is made to pass sleeve pipe 1, then sleeve pipe 1 is plugged in cable duct, make screwed pipe 6 gradually near block 3 by rotary handle 7, make rubber ring 2 times compression, then rubber ring 2 is extruded the full sleeve pipe 1 of rear filling and the gap in cable duct, then turn down rubber tube 5, rubber tube 5 is socketed on cable.
Be provided with in the present invention by briquetting and sleeve pipe extruding rubber ring, make rubber ring to circumference diffusion thus will the gap of full sleeve pipe and cable duct be filled, can by sleeve pipe and cable seal by rubber tube; Good sealing effect, is convenient to dismounting, and cable is because to expand with heat and contract with cold or other reason causes moves axially, and there is not impact to sealing.
The foregoing is only specific embodiments of the invention, but technical characteristic of the present invention is not limited thereto, any those skilled in the art is in the field of the invention, and the change done or modification are all encompassed among the scope of the claims of the present invention.
