Referring to fig. 1, 2, 7, 8 and 9, the present invention provides the following technical solutions: the utility model provides a heating network salvagees and has connecting device of self-align sealing function, first connecting block 3 bottom fixedly connected with connecting rod 25 in addition, connecting groove 26 has been seted up at second connecting block 4 top, connecting rod 25 outer wall size and connecting groove 26 inner wall size looks adaptation, two fourth mounting grooves 27 have been seted up to connecting rod 25 inside symmetry, two positioning blocks 28 have been seted up to the inside symmetry of two fourth mounting grooves 27, two constant head tanks 29 with positioning block 28 looks adaptation have been seted up to second connecting block 4 inside symmetry, two positioning blocks 28 are close to connecting rod 25's one end all fixedly connected with slider 30, two fourth mounting grooves 27 inside all are equipped with spring 31, connecting rod 25 inside symmetry has seted up two spouts 32 with slider 30 looks adaptation, two positioning blocks 28 pass through slider 30 and spout 32 sliding connection, spring 31 one end and slider 30 fixed connection, the other end and connecting rod 25 fixed connection, connecting rod 25 inside has seted up intercommunication groove 33, connecting rope 34 inside the intercommunication groove 33, connecting rope 34 one end and slider 30 fixed connection, connecting rope 34 outside is located to spring 31 cover, connecting rope 34 is Y type, first connecting block 3 inside is equipped with first connecting rope 35 and three-way connecting rope 34 outside the other end is connected to the inside the three-way connecting groove 35, three-way connecting rope 34 looks adaptation is connected to the other end, three-way connecting rope 34 outside size is connected to the other end 35.
The implementation mode specifically comprises the following steps: at present, the half joint is usually connected by bolts and nuts in the process of connection, a great amount of time is wasted in the process of connection, so that the pipeline cannot be rapidly salvaged, when a worker needs to salvage the pipeline by using the first connecting pipe 1 and the second connecting pipe 2, the worker firstly places the second connecting pipe 2 at the bottom of the pipeline, then places the first connecting pipe 1 at the top of the pipeline, the worker presses the first connecting pipe 1, so that the first connecting pipe 1 drives the first connecting block 3 to move downwards, the connecting rod 25 is simultaneously driven to enter the connecting groove 26 in the process of moving the first connecting block 3, the positioning block 28 is extruded by the second connecting block 4 in the process of entering the connecting groove 26, the positioning block 28 is moved after being extruded, at this time, the positioning block 28 moves smoothly along the sliding groove 32 through the sliding block 30, meanwhile, in the process of moving the sliding block 30, the sliding block 30 extrudes the spring 31, so that the spring 31 is in a contracted state, when the positioning block 28 moves to be at the same level with the positioning groove 29, at this time, the positioning block 28 is not extruded by the second connecting block 4 any more, at this time, the spring 31 is extruded by the positioning block 28 any more, at this time, the spring 31 rebounds to drive the sliding block 30 and the positioning block 28 to reset, so that the positioning block 28 can be connected with the positioning groove 29, so that the first connecting block 3 and the second connecting block 4 can be connected quickly, the time required by the staff to connect the first connecting pipe 1 and the second connecting pipe 2 is reduced, the waste of pipeline energy sources is reduced, when the staff subsequently needs to disassemble the first connecting pipe 1 and the second connecting pipe 2, at this time, the staff only needs to pull the pull block 36, the pull block 36 is used for pulling the connecting rope 34, at the moment, the connecting rope 34 can be used for pulling the sliding block 30 and the positioning block 28, so that the positioning block 28 is pulled out from the positioning groove 29, at the moment, a worker can separate the first connecting pipe 1 and the second connecting pipe 2, the worker can overhaul the connecting pipe conveniently, and the time required for the worker to disassemble and assemble the first connecting pipe 1 and the second connecting pipe 2 is shortened.
The working principle of the invention is as follows:
referring to fig. 1-6, through the cooperation use of gas collecting tube 9, rubber buffer 12, ejector pin 13 and sealing pad 15, make the staff be in with first connecting pipe 1 and second connecting pipe 2 connect the back, can drive mounting panel 7 through rotatory threaded rod 17 and remove, thereby make mounting panel 7 can extrude the inside air of first gasbag 16 at the in-process that removes, thereby make air get into gas collecting tube 9 inside, then the air passes through gas collecting tube 9 and gets into inside the second gasbag 22, when the protruding contact of pipeline outside with sealing pad 15, at this moment second gasbag 22 drive rubber buffer 12 and ejector pin 13 the preceding contact pipeline, at this moment second gasbag 22 inside gets into less gas, when pipeline outside recess and sealing pad 15 do not contact, at this moment second gasbag 22 inside gets into more gas, thereby make second gasbag 22 can drive ejector pin 13 extrusion sealing pad 15, thereby make sealing pad 15 can adjust according to the protruding or the recess of pipeline, thereby make pipeline and sealing pad 15 get closer, and then make things convenient for the staff to repair the pipeline, thereby prevent the extravagant of energy.
Further, refer to fig. 1, fig. 2, fig. 7, fig. 8 and fig. 9 of the specification, through the cooperation of locating piece 28, constant head tank 29, spring 31 and connecting rope 34, make the staff calibrate the back with connecting rod 25 and spread groove 26, then press first connecting pipe 1, in the in-process that locating piece 28 descends, locating piece 28 can receive the extrusion of second connecting block 4, at this moment locating piece 28 can accomodate into fourth mounting groove 27 inside, when locating piece 28 moves to with constant head tank 29 horizontal position, spring 31 can rebound and drive locating piece 28 and be connected with constant head tank 29 this moment, thereby make things convenient for the staff to install, when the staff need dismantle first connecting pipe 1 and second connecting pipe 2 and overhaul the maintenance, at this moment the staff pulls and draws piece 36 and drive connecting rope 34, at this moment connecting rope 34 can drive locating piece 28 to accomodate into fourth mounting groove 27 once more, at this moment the staff can split first connecting pipe 1 and second connecting pipe 2, thereby reduce the time that the staff need first connecting pipe 1 and second connecting pipe 2 to dismantle, and then can quick repair, thereby reduce the waste of resources.
Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present invention has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
