[0032] Reference Figure 4 In conjunction with the aforementioned structure, a pair of drilling platform connecting ear seats 31 are provided on the edge of the equipment platform of the drilling platform 33 , and the pair of drilling platform connecting ear seats 31 are used to dock with a pair of ear plates 9 .

[0033] The connection mode of the device of the present invention and the drilling floor equipment is:

[0034] 1) See Figure 1 The folding structure of the device of the present invention in the pre-installation state and the transportation state is the same, both of which are in the initial state. According to the layout of the drilling rig on site, the device of the present invention is moved to the installation position close to the base 34 of the drilling rig. Figure 5 ;

[0035] 2) Install the upper pipeline trough 17. Use a crane to lift the end of the support rod 10 of the upper pipeline trough 17, and connect and fix the connecting ear plate 9 on the upper pipeline trough 17 and the drilling platform connecting ear seat 31 on the drilling platform 33 with a pin shaft.

Figure 5 ;

[0037] 4) Finally, the lower cable duct 5 is pulled out from the box body 1 to the position of the electric control room 38, and the lower drag chain 4 moves with the lower cable duct 5, and the cables 30 in the lower drag chain 4 are connected to the electric control room 38, completing the connection of all cables 30 in the box-type cable duct.

[0038] The dismantling of the device of the present invention is opposite to the above steps. After the dismantling on the drilling rig is completed, it is hoisted and shipped as an integral unit.

[0039] The action description of the device of the present invention during the drilling rig lifting process:

[0040] 1) During the lifting process of the drilling rig base, the drilling platform 33 drives the upper pipeline trough 17 to rise, and the pipeline trough guide wheel 19 on the upper pipeline trough 17 moves forward along the pipeline trough guide groove 14. When the pipeline trough guide wheel 19 enters the groove 28 at the front end of the moving beam 13, the moving beam 13 begins to extend out of the box body 1 under the pull of the pipeline trough guide wheel 19. At the same time, the inclined block 1 25 and the inclined block 2 26 provided at the end of the guide platform 2 21 begin to disengage. At this time, the extension rod 24 extends out under the action of the spring 27 to block the pipeline trough guide wheel 19 from leaving the groove 28. The moving beam 13 reaches the limit limit. Figure 6 ;

[0041] 2) After the drilling rig base continues to rise to its full height, the limit block 12 limits the front roller 15, the upper pipeline trough 17 extends to the limit position, and the box-type pipeline trough also reaches the final working state. Figure 7 .

[0042] Description of the device of the present invention during lowering of the drilling rig and disassembly and separation of the box-type pipeline trough:

[0043] 1) When the drilling rig is lowered, the upper pipeline trough 17 drives the moving beam 13 back to the box body 1 through the pipeline trough guide wheel 19. When the inclined block 1 25 in the moving beam 13 contacts the inclined block 2 26, the extension rod 24 begins to retract under the guidance of the inclined surface of the inclined block 26. When the extension rod 24 is fully retracted, the pipeline trough guide wheel 19 continues to move away from the groove 28, and the upper pipeline trough 17 continues to enter the box body 1 along the pipeline trough guide groove 14;

[0044] 2) After the base and the drilling platform 33 are lowered, the cables 30 connecting the winch motor 35, the rotary table motor 36 and the driller's room 37 on the drilling platform 33 are removed and placed in the upper pipeline trough 17; then the connection between the connecting ear plate 9 and the drilling platform connecting ear seat 31 is removed, so that the upper pipeline trough 17 is completely inserted into the box body 1; the connection between the cable 30 between the lower pipeline trough 5 and the electric control room 38 is removed, and the lower pipeline trough 5 is pushed into the box body 1, completing the removal of the device of the present invention from the drilling rig, and completing the retraction of the structure, returning to the initial state. Figure 1 .

[0045] The present invention modularizes the drilling rig pipeline trough, which saves more than half of the assembly time compared with the existing structural pipeline trough assembly method; the cables do not need to be repeatedly arranged and removed from the pipeline trough when the drilling rig is assembled and disassembled, which effectively protects the cables from damage; the number of pipeline trough units is reduced, transportation is convenient, and the cost is reduced.
