[0032] like Figure 1-7As shown, an embodiment of the utility model proposes an easily replaceable electric protection tube, comprising a tube body 1 and a fixing frame 2 sleeved on the outside of the tube body 1, wherein the tube body 1 is divided into two half tube bodies, wherein a connecting groove 13 is provided on the top of the lower half tube body 12, and a connecting block 14 adapted to the connecting groove 13 is provided on the bottom of the upper half tube body 11, the upper half tube body 11 and the lower half tube body 12 can be quickly assembled or disassembled, and after the two half tube bodies are successfully assembled to form the tube body 1, the internal power cable can be protected. A limiting mechanism 3 and a driving mechanism are arranged in the fixed frame 2. The fixed frame 2 includes a lower frame body 22 and an upper frame body 21 hinged on the lower frame body 22. The limiting mechanism 3 includes a first limiting semi-ring 31 and a second limiting semi-ring 32. The first limiting semi-ring 31 is fixedly installed in the lower frame body 22 by bolts 24, and the second limiting semi-ring 32 is slidably connected in the upper frame body 21. The driving mechanism is installed on the upper frame body 21. The driving mechanism is used to control and drive the second limiting semi-ring 32 to rise and fall in the vertical direction, so as to move toward or away from the first limiting semi-ring 31. When the second limiting semi-ring 32 descends to contact with the first limiting semi-ring 31, the upper half tube body 11 and the lower half tube body 12 can be more firmly combined, thereby increasing the connection firmness of the two half tube bodies and avoiding the connection between the two half tube bodies from being disconnected and causing the cable to be exposed. A locking assembly is provided between the upper frame 21 and the lower frame 22. In fact, the locking assembly can be a buckle and a slot. The buckle is provided on the upper frame 21, and the slot engaged with the buckle is provided on the lower frame 22. In this embodiment, the locking assembly is a bolt 24 and a nut 25. Mounting blocks 23 are respectively provided on the upper frame 21 and the lower frame 22. Threaded holes are provided on the mounting blocks 23. One end of the bolt 24 passes through the two mounting blocks 23 and cooperates with the nut 25 to lock and fix the upper frame 21 and the lower frame 22. The connection is firm, so that the fixed frame 2 is installed very firmly. After the installation is successful, it will be difficult for non-human factors to cause the protective tube body to loosen.
[0033] like Figure 1-6 As shown, the driving mechanism includes a lifting component 4 and a power component 5. The power component 5 is used to drive the lifting component 4 to lift and lower. The lifting component 4 includes a sleeve 42, a lifting rod 43 and a mounting plate 41. The mounting plate 41 is fixedly installed above the second limiting semi-ring 32 by bolts 24. The sleeve 42 is rotatably passed through the mounting plate 41 through a bearing. The sleeve 42 has a cavity inside and is open at both ends. The bottom end of the lifting rod 43 is fixedly connected to the top of the second limiting semi-ring 32, and the top end is inserted into the sleeve 42. The lifting rod 43 is threadedly matched with the inner wall of the sleeve 42.
[0034] like Figure 4-6As shown, the lifting assembly 4 also includes a limit rod 44, and the top wall of the lifting rod 43 is provided with an inwardly recessed limit groove. The cross-section of the limit rod 44 is a regular polygon, and the shape of the limit groove is adapted to the limit rod 44. The top end of the limit rod 44 is fixedly connected to the inner wall of the upper frame 21, and the bottom end is inserted into the limit groove and is slidably connected to the lifting rod 43.
[0035] like Figure 6 As shown, the power assembly 5 includes a worm wheel 51 and a worm 52, the worm wheel 51 is fixedly sleeved on the sleeve 42, the worm 52 is rotatably mounted on the inner wall of the upper frame 21 through a fixing ring 53, and the worm 52 is meshed with the worm wheel 51 for transmission. The driving mechanism also includes an operating assembly 6, the operating assembly 6 includes a first bevel gear 61 and a crank 63, the first bevel gear 61 is fixedly sleeved on one end of the worm 52, one end of the crank 63 is located in the upper frame 21 and is fixedly sleeved with a second bevel gear 62 meshed with the first bevel gear 61 for transmission, the other end of the crank 63 passes through the upper frame 21 to form an operating end, and the crank 63 is rotatably connected to the upper frame 21.
[0036] In the above embodiment, the limiting rod 44 is square. By manually rotating the crank 63, the second bevel gear 62, the first bevel gear 61, and the worm 52 are driven to rotate, and then the worm wheel 51 and the sleeve 42 are driven to rotate. The lifting rod 43 does not rotate under the action of the limiting rod 44, so that the lifting rod 43 is lifted in the vertical direction, thereby realizing the vertical lifting of the second limiting semi-ring 32. The structure is simple and the operation is convenient. The two semi-tube bodies can be locked by the self-locking of the worm wheel 51 and the worm 52.
[0037] At least one limiting mechanism 3 is provided along the axial direction of the pipeline body 1, and the driving mechanism corresponds to the limiting mechanism 3 one by one. According to the length of the pipeline body 1, one or more limiting mechanisms 3 are adaptively provided. A sealing strip (not shown in the figure) is provided at the bottom of the connection groove 13 to increase the sealing of the connection between the connection block 14 and the connection groove 13. A plurality of sealing teeth can be provided on both sides of the sealing strip to further increase the sealing of the connection.
[0038] Working principle:
[0039] During installation, the upper half tube body 11 and the lower half tube body 12 are assembled into the pipe body 1, and the assembled pipe body 1 is placed on the first limiting semi-ring 31 of the lower frame 22, and the upper frame 21 is covered, and the upper frame 21 and the lower frame 22 are locked and fixed by bolts 24, and the crank 63 is turned, and the crank 63 drives the second bevel gear 62, the first bevel gear 61, the worm 52, the worm wheel 51, and the sleeve 42 to rotate, and the lifting rod 43 is lifted and lowered in the vertical direction under the action of the limiting rod 44, so that the second limiting semi-ring 32 descends and contacts with the first limiting semi-ring 31, and the installation is completed. The installation is quick and convenient.
[0040] During disassembly, turn the crank 63 to separate the second limiting half ring 32 from the first limiting half ring 31, loosen the bolt 24, open the upper frame 21, and easily separate the upper half tube 11 from the lower half tube 12. The disassembly is convenient and quick, and there is no need to pull the cable out of the entire pipeline or disconnect the cable in the conductive pipe body 1, which improves the replacement efficiency and does not require power off. In actual application, in order to prevent the crank 63 from rotating due to non-human factors, an openable and closable protective shell can be provided on the upper frame 21 to protect the crank 63.
