[0029] Embodiment

[0030] A prestressed intelligent tensioning device, comprising a device body and a pipe protection device, the device body is connected with an intelligent jack 7 through an oil way 6, and the pipe protection device is arranged at the connection between the device body and the oil way 6.

[0031] As shown in Figure 1 and Figure 2 , the device body comprises a shell, an oil pump box 8 and a main machine box 9 in the shell, the oil pump box 8 is arranged at the lower part in the shell, one side of the oil pump box 8 is provided with an oil inlet end and an oil return end, the corresponding position of the shell is provided with a through hole, and the oil inlet end and the oil return end are connected with the intelligent jack 7 through an oil inlet oil way and an oil return oil way respectively.

[0032] In this embodiment, an oil pressure gauge 10 is arranged on one side of the oil pump box 8 for monitoring the oil pump box 8.

[0033] The host box 9 is arranged on the upper part of the shell, and a display seat 11 for adjusting the host box 9 and the oil pump box 8 is arranged on the upper end of the host box 9. The display seat 11 comprises a data display screen 12, a control button 13 arranged on the right side of the display seat 11, and an adjusting knob 14 arranged on the right side of the control button 13.

[0034] In the embodiment, a push handrail is arranged on the outer wall of the front end of the shell, and a maintenance door is fixed by screws in the inner part of the outer wall of the two ends of the shell corresponding to the host box 9. The maintenance door can be used to timely maintain and replace the elements in the host box 9, and can also protect the elements in the host box 9 after the maintenance door is installed.

[0035] In the embodiment, a protection top cover 15 is arranged on the top of the shell, an opening handle is arranged on the outer wall of the front end of the protection top cover 15, the protection top cover 15 is connected to the rear end of the shell through two hinges, and the protection top cover 15 can be completely sleeved on the outside of the display seat 11 after being closed to the upper end of the shell, so as to protect the data display screen 12, the control button 13 and the adjusting knob 14 on the display seat 11, avoid the control button 13 and the adjusting knob 14 from being easily touched by mistake during movement, and also avoid the data display screen 12 from being easily scratched by external objects, thereby reducing economic loss.

[0036] In the embodiment, four moving wheels 16 are arranged on the four corners of the bottom of the shell, and the shell is fixedly connected with the four moving wheels 16 through screws. The four moving wheels 16 are universal wheels with brake functions, the lowermost ends of the four moving wheels 16 are kept on the same horizontal plane, and the four moving wheels 16 kept on the same horizontal plane can make the prestressed intelligent tensioning equipment more stable when moving on the ground, and cannot shake greatly. The universal wheel design of the moving wheels 16 can increase the moving flexibility, and the moving wheels 16 can be flexibly turned according to different moving positions.

[0037] As shown in Figure 3 The pipe protection device comprises a fixing ring 1, a connecting sleeve 2, a conical locking sleeve 3, a movable sleeve 4 and a soft steel wire connecting rope 5. The fixing ring 1 is arranged around the oil outlet end and the oil return end of the equipment body and is detachably connected with the shell through a plurality of screws. The connecting sleeve 2 is in the shape of a ring and is sleeved with the pipeline near the pipe head end of the oil path 6, and the inner diameter of the connecting sleeve 2 is the same as the outer diameter of the pipeline. The conical locking sleeve 3 is fixedly connected with the circular outer wall near the pipe head end of the connecting sleeve 2 and is arranged around the pipeline, and the tapered head end of the conical locking sleeve 3 faces the pipe head end. The outer surface of the conical locking sleeve 3 is provided with external threads. The movable sleeve 4 has a through cavity, and the inner surface of the cavity is provided with internal threads. The movable sleeve 4 is sleeved with the pipeline and is threadedly connected with the external threads of the conical locking sleeve 3. The two ends of the soft steel wire connecting rope 5 are connected with the outer walls of the fixing ring 1 and the connecting sleeve 2.

[0038] In the embodiment, the soft steel wire connecting rope 5 should be kept tight when the pipe protection device is used, so as to achieve the best protection effect and avoid the oil pipe 6 end from being pulled out.

[0039] In the embodiment, the conical locking sleeve 3 comprises a first gasket and a second gasket. The first gasket is conical and made of rubber material. The outer diameter of the head end of the first gasket is smaller than the inner diameter of the cavity of the movable sleeve 4, and the outer diameter of the tail end of the first gasket is larger than the inner diameter of the cavity of the movable sleeve 4. The first gasket is fixedly connected with the connecting sleeve 2, and the inner surface of the first gasket is in close contact with the pipeline. The second gasket is plate-shaped and made of hard material. A plurality of second gaskets are fixedly arranged on the outer surface of the first gasket at intervals, and the outer surface of the second gasket is provided with external threads. As the distance between the movable sleeve 4 and the tail end of the conical locking sleeve 3 gradually decreases, the friction between the conical locking sleeve 3 and the pipeline gradually increases, and the connection becomes tighter.

[0040] When the pipe protection device is used, the protection sleeve 4 is first connected with the head end of the conical locking sleeve 3, and then the oil line 6 is pulled towards the oil pump box 8 until the oil line 6 between the oil pump box 8 and the movable sleeve 4 is slightly bent. Then, the connecting sleeve 2 is continuously pushed towards the movable sleeve 4 while maintaining the state, so that the head end of the conical locking sleeve 3 further penetrates into the interior of the movable sleeve 4. Since the outer wall of the conical locking sleeve 3 is conical, further penetration into the interior of the movable sleeve 4 will cause it to gradually shrink, which will cause the conical locking sleeve 3 to shrink and lock the oil line 6 penetrating through its interior. In this way, the oil line 6 is locked and maintained in the adjusted state. When the oil line 6 is pulled outwards, the soft steel wire connecting rope 5 will replace the oil line 6 to bear the external force at this time, so as to avoid the connection between the oil line 6 and the inlet end and the outlet end from being loose and falling off.

[0041] The pipe protection device in the embodiment is arranged at the connection between the inlet oil line and the outlet oil line and the oil pump box 8, which protects the connection and avoids the connection between the inlet oil line and the outlet oil line and the inlet pipe end and the outlet pipe end from being loose and falling off due to external pulling. At the same time, it can also avoid the joint of the inlet pipeline and the outlet pipeline from being frequently bent and easily broken, thereby enhancing the stability of the internal oil pressure of the inlet oil line and the outlet oil line during work.

[0042] The technical features of the above embodiments can be combined in any way. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the description.

[0043] The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
