Abstract
The utility model relates to a temporary plugging device for a pipeline with a large caliber. The utility model is characterized in that the periphery of a plugging cover (1) is formed into an annular groove which is inosculated with a pipeline opening, and a rubber strip (2) is embedded in the groove; the plugging cover (1) is provided with a central screw thread sleeve (6) which is penetrated by an outer shaft sleeve (3) assembled by screw threads, and the outer shaft sleeve (3) is provided with a screw nut (7) which is connected with the plugging cover (1) by pulling ribs; the outer shaft sleeve (3) is assembled with an inner lead rod shaft (4) by screw threads, and the inner lead rod shaft (4) is provided with an upper screw nut (8), a lower screw nut (9) and a middle stopping block; the upper and the lower screw nuts (8, 9) are hinged by connecting rods with more than three supporting feet (5) which are arranged in the same circumferential direction, wherein, the rotary directions of the screw threads on the section of the lead rod shaft (4) which is provided with the screw nuts (8, 9) are opposite. The utility model has the advantages of tight plugging, firm and safe supporting feet, free expansion and contraction, and convenient assembly and disassembly. The utility model can be operated by one person and has the function of theft prevention.
Description
(1) technical field:
The utility model belongs to the interim plugging device of heavy-caliber pipeline
(2) background technique:
In the construction pipeline process, as not constructing continuously, its pipeline mouth is wanted interim shutoff.But pipeline plugging device manufacturing in the past is coarse, at will fills in some soft-bodies, can prevent roughly that sandstone from entering in using at the scene, can prevent that dust, sandstone, wind and rain etc. from entering pipeline down, and poor sealing performance can not meet the demands.
(3) model utility content:
Technical problem to be solved in the utility model is at the problem of depositing in the background technique, and a kind of interim plugging device of heavy-caliber pipeline of good sealing effect is provided.
The invention for solving the technical problem can reach by following technical solution: the annular groove in that the formation of this capping periphery can match with the pipeline mouth studs with rubber strip in this groove; The center thread bush is arranged on the capping, by being the external axle sleeve of screw fit in this cover, loading nut on the external axle sleeve, nut is connected with capping by lacing wire; By the interior lead screw shaft of screw fit, upper and lower nut and middle block are housed on the interior lead screw shaft in the external axle sleeve, upper and lower nut is by hinge bar and hinged with 3 above spikes of circumferential arrangement; Upper and lower section last thread rotary orientation of thick stick axle that nut wherein is housed is opposite.
This pipeline plugging device mainly divides two-part, and the one, by thread bush on the rotation capping, utilize the principle of relative movement, outer shaft is motionless, and the big lid of shutoff is moved to pipeline, and the big lid that has rubber pad contacts with pipeline, make the pipeline shutoff very tight, can prevent that dust, wind and rain, sandstone from entering; The 2nd, the positive left-hand thread of axle in utilizing makes the leading screw upper skeleton do to stretch, contract mobile, and spike and distance of shaft centers are from stretching arbitrarily on it, and three spikes firmly support in the pipeline inwall.
The utility model is compared with background technique has following beneficial effect: the major advantage shutoff is tight, the firm safety of spike, flexible free, easy to loading and unloading, and a people can operate, and antitheft effect is arranged.Shutoff is tight: in design process, cover greatly at plugging device rubber pad has been installed in order to address this problem us, utilize the principle of relative movement when the outer shaft that has screw thread, the motionless big lid of shutoff that makes of outer shaft moves to pipeline, the rubber at Da Gai edge promptly is pressed on the pipeline mouth tightly, makes shutoff very tight.Reached windproof, rainproof, dust-tight purpose fully.Spike is firmly safe in utilization: three spikes adopt the parallels of 70mm * 70mm, catch the inwall of pipeline firmly, and the frictional force of increase and pipeline inwall has been strengthened the Security in the using process.Flexible free: the positive and negative screw thread of axle in utilizing, silk is shouldered round about moved, skeleton drives three spikes and freely stretch, uses very flexibly, and a cap that is connected with leading screw has certain distance of freely stretching, and manually can regulate, and makes the scope of stretching very big.The single operation easy to loading and unloading: this plugging device can be divided into four parts, and each one processes separately, connects together during use and can operate, and loads and unloads very conveniently, singlely during operation can make the pipeline shutoff tight.Antitheft: stolen in order to prevent in design process, processed special nut at big tops, supporting handling instrument must be arranged, can operate, we have been plugging device system special spanner prevents the generation of stealing in the on-the-spot using process.
(4) description of drawings:
Accompanying drawing 1 is the plugging device installation diagram;
Accompanying drawing 2 is Fig. 1 capping 1 cross-section profiles;
Accompanying drawing 3 is external axle sleeve 3 sectional drawings on Fig. 1;
Accompanying drawing 4 is interior lead screw shaft 4 diagrammatic sketch on Fig. 1.
(5) embodiment:
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
By shown in Figure 1, the annular groove in that capping 1 peripheral formation can match with the pipeline mouth studs with rubber strip 2 in this groove; Center thread bush 6 is arranged on the capping 1, and by in this cover being loading nut 7 on the external axle sleeve 3, external axle sleeve 3 of screw fit, nut 7 is connected with capping 1 by lacing wire; 3 li of external axle sleeves are equipped with upper and lower nut (8,9) and middle block by the interior lead screw shaft 4 of screw fit on the interior lead screw shaft 4, upper and lower nut with hinged with the above spike of 3 of circumferential arrangement 5, constitutes telescopic arched framework by hinge bar; 4 upper and lower sections last thread rotary orientations of thick stick axle that nut (8,9) wherein is housed are opposite.
In such scheme, in implementation process, we adopt special spanner, and an end is square, and an end is a flower shape.As long as operator cooperate spanner with the nut of the side of covering greatly, drive big lid when inwardly rotating and move the tight big lid of envelope to the mouth of pipe for outer shaft, separate with the mouth of pipe if when inner rotary, be about to cover greatly; For when the inner rotary, spike separates with the pipeline inwall, can unload plugging device, and the whole operation process is very easy, and single can the operation reduced working strength of workers in the construction using process, improved working efficiency.
Claims (1)
