Specifically, the cable guide tube 100 is loaded into the positioning skeleton 20, and after the position of the cable guide tube 100 is adjusted in place, the position of the cable guide tube 100 can be fixed by using a limiting steel.

[0042] In one embodiment, the positioning frame 20 includes a column 22, a flat link 24, and a diagonal brace 26. The column 22 extends along the length direction of the horizontal beam 16, and the flat link 24 connects two adjacent columns 22, and four flat links 24 form a rectangle. The diagonal brace 26 is supported between two adjacent columns 22 along the length direction of the column 22 to ensure that the positioning frame 20 meets the rigidity of the cable guide 100 for operation and installation on the tower. The positioning frame 20 is trapezoidal so that the cable guide 100 can be installed and positioned at an angle.

[0043] The adjustment mechanism 30 is movably disposed on the tire frame 10, and the adjustment mechanism 30 can hoist the cable guide tube 100 to adjust the posture of the cable guide tube 100 on the positioning frame 20, so that the cable guide tube 100 is in a posture installed on the tower. In one embodiment, the adjustment mechanism 30 includes a traveling frame 32, a roller 34 and an adjustment hoist 36. A track 38 is provided on the base structure 12. Specifically, the track 38 is set on the steel plate surface layer 124. The roller 34 is installed at the bottom of the traveling frame 32, and the roller 34 is movably disposed on the track 38, and the adjustment hoist 36 is installed on the traveling frame 32.

[0044] In one embodiment, two groups of tracks 38 are provided, and the two groups of tracks 28 are arranged at intervals on the steel plate surface layer 124, and the walking frame 32 spans above the positioning frame 20. Specifically, the walking frame 32 includes a crossbeam and two legs, and the two legs are respectively connected to the two ends of the crossbeam, and the two legs are both equipped with rollers 34, and the rollers 34 on the two legs are respectively movably arranged on the two groups of tracks 38.

[0045] The adjusting hoist 36 is arranged on the traveling frame 32, and the adjusting hoist 36 is used to hoist the cable guide tube 100. Specifically, the adjusting hoist 36 is connected with a hook, and the hook can hook the adjusting lug on the cable guide tube 100 to achieve the hoisting of the cable guide tube 100. In one embodiment, the adjusting hoist 36 is arranged on the crossbeam, and the adjusting hoist 36 is a hand chain hoist.

[0046] See also Figure 4 The present invention also provides a cable conduit installation method. To implement the cable conduit 100 construction method, the cable conduit positioning device described above is used. Specifically, the installation method includes the following steps:

[0047] Step S110 : Install the cable guide tube 100 into the positioning frame 20 , and install the adjusting lug on the cable guide tube 100 .

[0048] Specifically, before the cable guide tube 100 is assembled, anchor bars are installed on the cable guide tube 100 in advance to facilitate the transportation and fixation of the cable guide tube 100. Then the cable guide tube 100 is hoisted into the positioning frame 20, and an adjustment lug is welded at the anchor bar of the cable guide tube 100, and the adjustment lug can facilitate the adjustment mechanism 30 to hoist the cable guide tube 100.

[0049] In one embodiment, before the above step S110, the above installation method further includes: statistically analyzing the inner diameters of the cable guide tubes 100 used in the project, and designing and processing a cable guide tube positioning device that meets all specifications of the cable guide tubes 100 according to the interval values ​​of various lengths and weights. Before the cable guide tube 100 is assembled, the height difference of the horizontal beam 16 is checked, and then the positioning frame 20 is processed on the horizontal beam 16.

[0050] Specifically, the horizontality of the horizontal beam 16 can be checked with a level gauge or other instrument to control the height difference error within 2 mm. The positioning frame 20 is designed to meet the rigidity of the cable guide 100 tooling and tower installation. The number of positioning frames 20 can be two, and the two positioning frames 20 are arranged side by side and spaced apart.

[0051] Step S120: the adjustment mechanism 30 adjusts the position of the outlet end 110 of the cable guide tube 100, and then fixes the outlet end 110 of the cable guide tube 100. The adjustment mechanism 30 moves to the anchor end 120 of the cable guide tube 100, adjusts the anchor end 120 to a position, and then fixes it.

[0052] Specifically, according to the measurement instruction, the adjustment hoist 36 is connected to the adjustment lug, and the adjustment mechanism is used to fine-tune the outlet end 110 of the cable guide tube 100 in various directions, and the outlet end 110 of the cable guide tube 100 is fixed after it is adjusted in place. In one embodiment, after the outlet end 110 of the cable guide tube 100 is adjusted in place, two limiting steels are made at the outlet end 110 of the cable guide tube 100, and the limiting steels are angle steels. The outlet end 110 of the cable guide tube 100 is limited between the two limiting steels, and the end face of the cable guide tube 100 abuts against one of the limiting steels.

[0053] Then, the adjustment mechanism 30 is moved to the vicinity of the anchoring end 120 of the cable guide tube 100, and the adjustment mechanism 30 adjusts the position of the anchoring end 120 of the cable guide tube 100, and fixes the anchoring end 120 after the adjustment is in place. In one embodiment, the anchoring end 120 of the cable guide tube 100 is limited by anchor bars.

[0054] Step S130: retest the outlet end 110 and the anchoring end 120 of the cable guide tube 100, and reinforce the cable guide tube 100 after confirming that they are correct.

[0055] Specifically, after the cable guide tube 100 is adjusted in place, the outlet end 110 and the anchor end 120 of the cable guide tube 100 are retested to see if the posture of the cable guide tube 100 meets the requirements. If not, the adjustment mechanism 30 is used to fine-tune the cable guide tube 100 again. After it is correct, anchor bars are used for reinforcement, and the anchor bars are welded to the positioning frame 20 to prevent damage to the outer wall of the cable guide tube 100.

[0056] Step S140: Install a plane limiting device on the tower to limit the positioning frame 20 within the plane limiting device.

[0057] Specifically, before installing the positioning frame 20, the column foot position is laid out on the tower, and after adjusting the elevation, the plane limit device is welded, and the column foot of the positioning frame 20 is placed in the plane limit device to quickly determine the installation position of the positioning frame 20. The higher the accuracy of the positioning frame 20 and the column foot laying accuracy are controlled, the higher the efficiency of installation on the tower.

[0058] In one embodiment, the process of welding the plane limiting device is as follows: pre-embed column feet on the tower according to the size of the positioning frame 20, weld steel plates on the column feet, and weld the limiting column feet on the steel plates to realize the production of the plane limiting device. The limiting column feet are angle steels, and the four corners of the positioning frame 20 are limited in the four angle steels.

[0059] Step S150: retest the cable guide tube 100 installed on the tower, and fix the positioning frame 20 after confirming that it is correct, thereby completing the installation of the cable guide tube 100.

[0060] Specifically, after the installation position of the positioning frame 20 is fixed, the cable guide tube 100 installed on the tower is retested, and after being correct, the column foot of the positioning frame 20 and the limiting column foot are welded together to complete the fixing of the positioning frame 20 and the installation of a set of cable guide tubes 100. Finally, according to the above method, the installation of the entire bridge cable guide tube 100 is completed.

[0061] The cable guide tube positioning device and the cable guide tube installation method utilize the adjustment mechanism 30 to adjust the position of the cable guide tube 100, quickly and accurately locate the tooling of the outlet end 110 of the cable guide tube 100 and the anchoring section, and the installation position can be quickly determined by the plane limit device. The operator can quickly tool the cable guide tube 100 in the back field, thereby reducing the installation operation time on the tower, reducing the risk of high-altitude operations, and having high installation efficiency and accuracy, thereby reducing production costs.
