The positive and negative spherical surface telescopic moving mechanism along the central line of the pipe orifice is technically characterized in that: the invention is further developed in the following with reference to the accompanying drawings.
As shown in fig. 1 and 6, when two nozzles 3 and 4 are in air butt joint operation, the central lines 8 and 8 'of the more hemispherical body 1 and the less hemispherical body 2 must be respectively positioned on the central lines 13 and 13' of the two butt joint nozzles and can move back and forth along the central lines of the respective nozzles. Therefore, a regular pyramid (regular triangular pyramid, regular rectangular pyramid or regular pentagonal pyramid) frame synchronous telescopic mechanism is required to be arranged, and the regular pyramid frame synchronous telescopic mechanism is composed of a bottom synchronous telescopic mechanism and a side edge synchronous telescopic mechanism. The bottom synchronous telescopic mechanism and the lateral edge synchronous telescopic mechanism can realize synchronous telescopic through a hydraulic technology.
As shown in fig. 1 and 5, the bottom telescoping mechanism of the regular pyramid frame is composed of a plurality of bottom star-shaped telescoping rods 10 supported by a star-shaped telescoping rod central connecting piece 11, and each bottom star-shaped telescoping rod 10 is provided with a hydraulic pipe connector 19. All bottom star-shaped telescopic rods 10 and star-shaped telescopic rod central connecting pieces 11 are connected in a long circular hole hinged mode, and the tail ends of the star-shaped telescopic rods are connected with a top foot 15; the bottom telescopic mechanisms of the regular pyramid frames can synchronously extend under the hydraulic action, so that all the supporting feet 15 at the bottoms of the regular pyramid frames are pressed against the inner wall of the pipe orifice, and the regular pyramid frames are fixed in the pipe orifice. The bottom of the top leg 15 is serrated, so that the friction force between the synchronous telescopic rod 10 and the pipe wall is increased, and the sliding is prevented.
As shown in fig. 1 to 6, the side edge synchronous telescopic mechanism of the regular pyramid frame is composed of a plurality of side edge synchronous telescopic rods 7 using a plurality of hemispherical body brackets (23) or a few hemispherical shell brackets 23' as connecting pieces, the number of the side edge synchronous telescopic rods 7 is equal to that of the bottom star-shaped telescopic rods 10, and each side edge synchronous telescopic rod 7 is provided with a hydraulic pipe connector 19. The multi-hemispherical body 1 and the small hemispherical shell 2 are arranged on the top of a regular pyramid consisting of lateral edge synchronous telescopic rods 7 through a multi-hemispherical body bracket 23 and a small hemispherical shell bracket 23', and when the two pipe orifices 3 and 4 are butted in the air, the central lines 8 and 8' of the multi-hemispherical body 1 and the small hemispherical shell 2 are superposed with the central lines 13 and 13' of the two butted pipe orifices. The side edge synchronous telescopic rod 7 is connected with the multi-hemispherical body bracket 23 or the few-hemispherical body bracket 23 'and the top foot 15 on which the multi-hemispherical body bracket or the few-hemispherical body bracket 23' is arranged in a hinged manner. When all the side edge rods 7 of the regular pyramid frame device contract synchronously, the multi-hemispherical body 1 or the low-hemispherical shell 2 can move along the central line of the respective pipe orifice.
The synchronous telescopic mechanism of the regular pyramid frame has two states. When all bottom star-shaped telescopic rods 10 of the bottom telescopic mechanism of the regular pyramid frame extend, the top foot 15 is fixed on the pipe wall, the side edge synchronous telescopic rod 7 can synchronously extend and retract, and at the moment, the regular pyramid frame synchronous telescopic mechanism is in a use function; after the equipment is used, the bottom central connecting piece shaft 9 can be synchronously contracted, the tight jacking and fixing with the pipe wall are released, and the telescopic mechanism is folded and contracted to be in a retracted state. In order to realize the switching between the two states of the synchronous telescopic mechanism of the regular pyramid frame, a central connecting piece long circular hole 12 and a telescopic rod limiting insertion hole 20 on the bottom surface of the regular pyramid are arranged on a star-shaped telescopic rod central connecting piece 11 on the bottom surface of the regular pyramid, so that the bottom central connecting piece shaft 9 can be switched between an extension locking state and a contraction state.
If the content space of the butt joint pipe orifice is limited, the bottom star-shaped telescopic mechanism of the regular pyramid can be omitted, so that all the independent Y-shaped synchronous telescopic rods 27 are connected with the multi-hemispherical body bracket 23 or the few-hemispherical shell bracket 23' in a manner of long circular hole hinge to form the independent star-shaped synchronous telescopic mechanism. The independent star-shaped synchronous telescopic mechanism can be switched between a hinged rotation state and a locked rotation state through the independent Y-shaped synchronous telescopic rod long circular hole 28. When the telescopic rod is used, the hinging and rotating functions of all the independent Y-shaped synchronous telescopic rods 27 and the multi-hemispherical body bracket 23 or the few-hemispherical shell bracket 23' are locked, and the central lines of the independent Y-shaped synchronous telescopic rods 27 are positioned in the same plane. After the use is finished, the independent Y-shaped synchronous telescopic rod 27 is drawn out along the long round hole 28 of the independent Y-shaped synchronous telescopic rod and then folded and bundled.
As shown in fig. 1 to 5, the guide rope mechanism is composed of a pull rope 6 inserted through a first rope hole 5 of the multi-hemispherical body 1 and a second rope hole 5' of the small hemispherical shell 2, and a rope receiver 16 and a rope gripper 17 at both ends of the pull rope. When the two pipe orifices are in butt joint in the air, if the rope collecting device 16 is positioned at one side of the first rope hole 5 facing the pipe orifices, the rope clamping device 17 is positioned at one side of the second rope hole 5' facing the pipe orifices; on the contrary, if the rope retracting device 16 is located at the side of the second rope hole 5' facing the pipe orifice, the rope clamping device 17 is located at the side of the first rope hole 5 facing the pipe orifice.
The butt joint method comprises four processes of installation equipment, indirect butt joint, direct alignment and detachment.
Firstly, fixing a regular pyramid frame synchronous telescopic mechanism provided with a plurality of hemispherical bodies 1 (or fixing an independent star-shaped synchronous telescopic mechanism provided with a plurality of hemispherical bodies 1) in a pipe orifice 3, and fixing a regular pyramid frame synchronous telescopic mechanism provided with a few hemispherical shells 2 in a pipe orifice 4; or the regular pyramid frame synchronous telescopic mechanism provided with the less hemispherical shell 2 (or the independent star-shaped synchronous telescopic mechanism provided with the less hemispherical shell 2) can be fixed in the pipe orifice 4, and the regular pyramid frame synchronous telescopic mechanism provided with the more hemispherical bodies 1 can be fixed in the pipe orifice 4. The first rope hole 5 or the second rope hole 5' provided with the rope collecting device 16 is conveyed into the pull rope 6, and a section of the pull rope conveyed out is left with more allowance.
The centre lines 13 and 13' of the two nozzles are then lifted to the same height by means of a lifting device. The surplus stay rope 6 section which is worn out by the worker in the pipe orifice provided with the rope collecting device 16 is thrown into the opposite pipe orifice provided with the rope clamping device 17, the worker in the pipe orifice penetrates the stay rope 6 from the first rope hole 5 or the second rope hole 5' in the pipe orifice to the inner direction of the pipe orifice from the outside of the pipe orifice, the stay rope 6 is tensioned after the stay rope passes out, and the stay rope 6 is clamped and fixed by the rope clamping device 17 at the outer side of the rope hole.
And (3) indirect butt joint, wherein the pull rope 6 is continuously tightened through the rope stirring and rotating collector 16, so that the multi-hemispherical body 1 and the few-hemispherical shell 2 are gradually close to each other, and after the distance is close, the electromagnet in the multi-hemispherical body 1 is electrified, and the multi-hemispherical body 1 and the few-hemispherical shell 2 are attracted to form a spherical hinge, so that the indirect butt joint is realized.
