Detailed Implementation

[0015] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of this utility model.

[0016] like Figure 1-3 As shown, this utility model provides a special tooling for RTP pipe joints, including a frame 1, one end of which is provided with a joint body fixing plate 2; a hydraulic cylinder 15 is fixedly mounted on the frame 1, and the output end of the hydraulic cylinder 15 is fixedly connected to a clamping block seat 17, on which an RTP pipe clamping block 16 is mounted, the RTP pipe clamping block 16 is used to clamp an RTP pipe 10, and the RTP pipe clamping block 16 is coaxially arranged with the joint body fixing plate 2; a pressure block support mechanism and a tensioning sleeve support mechanism are also slidably mounted on the frame 1; the pressure block support mechanism and the tensioning sleeve support mechanism are located between the joint body fixing plate 2 and the RTP pipe clamping block 16.

[0017] In another embodiment, the pressure block support mechanism includes a first slider 6, a first slide table, a lead screw 8 with a handwheel, and a pressure block support 7; a first guide rail 5 is fixedly mounted on the frame 1; the first slider 6 is slidably mounted on the first guide rail 5, the first slide table is fixed on the first slider 6, the first slide table is provided with a threaded hole, and the lead screw 8 with a handwheel is screwed into the threaded hole; the pressure block support 7 is fixedly mounted on the top end of the lead screw 8 with a handwheel.

[0018] In another embodiment, the tensioning sleeve support mechanism includes a second slider 13, a second slide table, and a tensioning sleeve support 12; a second guide rail 14 is fixedly disposed on the frame 1; the second slider 13 is slidably disposed on the second guide rail 14, the second slide table is fixed on the second slider 13, and the tensioning sleeve support 12 is fixed on the second slide table.

[0019] In another embodiment, the connector body fixing plate 2 is provided with studs that are compatible with the bolt holes of the connector body 3.

[0020] In practical use, the frame 1 can be fixed in the factory or installed on a small tool cart. During operation, first install the connector body 3 with the pre-installed seal onto the connector body fixing plate 2 and secure it with nuts 4; then place the RTP pipe 10 onto the RTP pipe clamp 16 and fix it, leaving a certain length of RTP pipe 10 on the side of the RTP pipe clamp 16 near the connector body fixing plate 2, at which point the hydraulic cylinder 15 is in the extended state; next, install the tensioning sleeve 11 onto the reserved length of RTP pipe 10 and push the tensioning sleeve 11 onto the tensioning sleeve support 12; then activate the hydraulic cylinder 15 to retract it, causing the hydraulic cylinder 15 to drive the clamp seat 17, RTP pipe clamp 16, and RTP pipe 10 to slowly move towards the connector body 3, keeping the RTP pipe 10 concentric with the connector body 3 during the movement, until the end of the RTP pipe 10 is inserted into the root of the connector body 3; then release... Open the RTP pipe clamp 16 to release the fixation of the RTP pipe 10, and drive the hydraulic cylinder 15 to extend and reset; move the second slide towards the clamp seat 17 to make room, and then install the n clamping blocks 9 sequentially from bottom to top onto the connector body 3.

Then move the first slide closer to the connector body fixing plate 2, and then move the second slide closer to the connector body 3 so that the tensioning sleeve 11 covers the clamping block 9. Then use a hook wrench to screw the tensioning sleeve 11 onto the thread on the connector body 3 until it is tightened. Finally, loosen the nut 4 on the connector body 3, and the entire connector installation is completed.
