Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1-4 , the present utility model provides two technical solutions:

[0025] The first embodiment: A hydraulic pipe jacking tee connection structure includes a connecting pipe 1. A connecting mechanism 2 is arranged on the outer side of the connecting pipe 1 for diverting and transporting hydraulic oil. The connecting mechanism 2 includes:

[0026] A communicating component 21, which is arranged at the right end of the connecting pipe 1 for transporting hydraulic oil;

[0027] The connecting component 22 is arranged at the left end of the connecting pipe 1 for shunting and conveying hydraulic oil. The connecting component 22 includes a connector 221 fixedly installed at the left end of the connecting pipe 1. A second communicating pipe 227 is movably installed on the outer side of the connector 221. A first connecting frame 224 is movably installed on the top surface of the second communicating pipe 227. A second connecting frame 225 is movably installed on the bottom surface of the second communicating pipe 227. A shunting component for shunting and conveying hydraulic oil is arranged on the top surface of the first connecting frame 224. The shunting component includes a communicating groove 223 opened on the top surface of the first connecting frame 224, and the cross section of the communicating groove 223 is trapezoidal. A placing groove 228 is opened on the bottom surface of the second connecting frame 225, and the cross section of the placing groove 228 is trapezoidal. A first communicating pipe 226 is threadedly installed inside the placing groove 228, and a sealing gasket is fixedly installed on the top surface of the first communicating pipe 226. A pressing block 222 is threadedly installed inside the communicating groove 223, and a sealing gasket is fixedly installed on the bottom surface of the pressing block 222. The bottom surface of the first connecting frame 224 is closely attached to the top surface of the second connecting frame 225. The first connecting frame 224 and the second connecting frame 225 are connected together by bolts. The top surface of the placing groove 228 penetrates through the bottom surface of the second connecting frame 225 and extends to the top surface of the second connecting frame 225. The bottom surface of the communicating groove 223 penetrates through the top surface of the first connecting frame 224 and extends to the bottom surface of the first connecting frame 224. The bottom end of the pressing block 222 threadedly penetrates through the inside of the second communicating pipe 227 and extends into the inside of the connector 221, and the hydraulic oil can flow out through the connector 221 along the second communicating pipe 227 for conveying through the pressing block 222.

[0028] The first communicating pipe 226 and the second communicating pipe 227 can be used to shunt and convey hydraulic oil. During use, press the ultra-high pressure manual pump to make the hydraulic oil enter the inside of the connector 221 from the connecting pipe 1 through the communicating component 21, and then the hydraulic oil will flow out of the connector 221 and be conveyed through the second communicating pipe 227. When it is necessary to shunt the hydraulic oil, screw out the first communicating pipe 226 from the inclined plate 218, then screw out the pressing block 222 from the inside of the communicating groove 223, then insert the first communicating pipe 226 into the inside of the communicating groove 223 and rotate it so that one end of the first communicating pipe 226 is inserted into the inside of the second communicating pipe 227 and abuts against the inside of the connector 221. At this time, part of the hydraulic oil can be conveyed through the first communicating pipe 226, which is convenient for shunting the hydraulic oil and has good practicability.

[0029] The second implementation mode is mainly different from the first implementation mode in that: the connecting component 21 includes an insertion tube 212 movably installed at the right end of the connecting pipe 1. A first nut 213 is threadedly installed on the outer side of the insertion tube 212. The right end of the insertion tube 212 is movably installed with an outer tube 214. An oil delivery pipe 211 is fixedly installed at the right end of the outer tube 214. A slot 215 is opened at the left end of the outer tube 214, and a sealing gasket is fixedly installed on the right side of the slot 215. A plurality of grooves 216 are opened on the outer side of the left end of the slot 215, and the plurality of grooves 216 are evenly distributed in a circumferential manner at the left end of the outer tube 214. Connecting plates 217 are fixedly installed on the left sides of the plurality of grooves 216. An inclined plate 218 is fixedly installed on the outer side of the connecting plate 217, and the right side of the inclined plate 218 is a slope. A clamping block 2110 is fixedly installed on the inner side of the connecting plate 217. A plurality of clamping grooves 219 are opened on the outer side of the insertion tube 212, and the plurality of clamping grooves 219 are adapted to the clamping block 2110. A second nut 2111 is threadedly installed on the outer side of the outer tube 214. The left end of the first nut 213 is threadedly installed at the right end of the connecting pipe 1. The right end of the insertion tube 212 is movably inserted into the slot 215. Rotating the second nut 2111 to move leftward and pressing on the outer side of the inclined plate 218 causes the connecting plate 217 to move inward, and then the connecting plate 217 will drive the clamping block 2110 to be stuck in the plurality of clamping grooves 219 to fix the position of the outer tube 214.

[0030] The provided outer tube 214 and connecting plate 217 facilitate the disassembly and replacement of the oil delivery pipe 211. When the oil delivery pipe 211 needs to be replaced, rotate the second nut 2111 to move rightward. At this time, the second nut 2111 will leave the outer side of the inclined plate 218 to reset the connecting plate 217. Then the connecting plate 217 will drive the oil delivery pipe 211 out of the clamping grooves 219. Then the insertion tube 212 can be pulled out of the slot 215. Then the oil delivery pipe 211 can be replaced, which is convenient and fast.

[0031] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0032] During use, the user connects the oil delivery pipe 211 to the output end of the ultra-high pressure manual pump, and then presses the ultra-high pressure manual pump to make the hydraulic oil enter the inside of the connector 221 from the connecting pipe 1 through the connecting component 21. Then the hydraulic oil will flow out of the connector 221 and be transported through the second connecting pipe 227. When the hydraulic oil needs to be branched, screw out the first connecting pipe 226 from the inclined plate 218, then screw out the pressing block 222 from the inside of the connecting groove 223. Then insert the first connecting pipe 226 into the connecting groove 223 and rotate it so that one end of the first connecting pipe 226 is inserted into the second connecting pipe 227 and abuts against the inside of the connector 221. At this time, part of the hydraulic oil can be transported through the first connecting pipe 226, which is convenient for the branched transportation of the hydraulic oil.
