[0029] Example 1

[0030] Referring to Figures 1 to 6 The utility model provides a kind of cable well cable laying guide frame, including several annular intermediate sections 1, adjacent two groups of intermediate sections 1 are connected by the circumferential array of several groups of connection units 2;

[0031] The spacing of intermediate section 1 is adjusted by the unfolding of connection unit 2, and different well depth requirements are quickly matched without disassembling structure;

[0032] Two intermediate sections 1 at both ends are rotatably provided with rotary table 3, and guide element 4 is fixedly arranged on rotary table 3.

[0033] A plurality of legs 5 are also rotatably arranged on the two intermediate sections 1 at the two ends, each leg 5 being rotatably arranged on the side wall of the intermediate section 1;

[0034] A drive ring 6 is also rotatably arranged on the two intermediate sections 1 at the two ends, a plurality of control rods 7 being rotatably arranged on the drive ring 6, each control rod 7 being rotatably connected to the corresponding leg 5 at the end away from the drive ring 6, and the drive ring 6 being capable of synchronously adjusting the unfolding angle of the legs 5 when it rotates.

[0035] The drive ring 6 synchronously controls the unfolding angle of all the legs 5 when it rotates, thereby realizing self-adaptive multi-point support of the guide frame on the well wall and improving the fixing efficiency;

[0036] The guide frame as a whole is placed into the cable well, the axial length of the guide frame is adjusted by synchronously unfolding the connecting units 2 between adjacent intermediate sections 1 to adapt to the well depth;

[0037] The pre-installed integrated intermediate sections 1, legs 5 and drive ring 6 structure only needs to be unfolded to complete the adaptation, thereby simplifying the construction process;

[0038] By rotating the drive ring 6 on the intermediate section 1, all the legs 5 are synchronously unfolded in the direction of the well wall through the linkage of the control rods 7 on the drive ring 6, so that the foot pads 13 at the ends of the legs 5 abut against the well wall to form stable support,

[0039] The cable is guided through the guide 4 on the turntable 3 of the intermediate section 1 at the two ends, the cable enters the annular channel formed by the intermediate section 1 through the guide 4, and the lower part of the cable enters the underground pipe gallery through the guide 4.

[0040] The connecting unit 2 comprises two connecting rods 8 rotatably connected in sequence at the head and tail, and the movable ends of the two connecting rods 8 are rotatably connected to the two intermediate sections 1, respectively.

[0041] By adjusting the axial movement of adjacent intermediate sections 1, the two connecting rods 8 of the connecting unit 2 are unfolded or folded around their rotation connection points, thereby realizing the expansion and contraction adjustment of the distance between the intermediate sections 1 to match the depth of the cable well;

[0042] The circumferentially arrayed connecting rod 8 structure of the connecting unit 2 forms a stable support frame after the intermediate section 1 is unfolded, thereby preventing the intermediate sections 1 from being deflected or twisted.

[0043] The guide 4 comprises a mounting seat 9 fixedly arranged on the turntable 3, and two guide rollers 10 rotatably arranged on the mounting seat 9, one of the guide rollers 10 being arranged close to the shaft of the turntable 3, and the other being arranged close to the outer wall of the turntable 3.

[0044] The cable is introduced from above the guide roller 10 close to the outer wall of the rotating disc 3, supported by the guide roller 10, and then moves radially along the rotating disc 3 to the guide roller 10 close to the axis of the rotating disc 3, and is jointly constrained by the two guide rollers 10 to form a smooth downward curved path.

[0045] According to the diameter of the cable and the laying direction requirement, the contact angle of the cable and the guide 4 is adaptively adjusted by the rotation characteristics of the two guide rollers 10, so as to reduce the sliding friction.

[0046] The guide 4 at the lower end introduces the cable from above the guide roller 10 close to the axis of the rotating disc 3, supports the cable through the guide roller 10, and then moves the cable to the guide roller 10 close to the outer wall of the rotating disc 3, and is jointly constrained by the two guide rollers 10 to form a smooth curved path, so as to facilitate the cable to enter the underground pipe gallery.

[0047] The distance between the guide roller 10 close to the axis of the rotating disc 3 and the rotating disc 3 is less than the distance between the other guide roller 10 and the rotating disc 3.

[0048] The two guide rollers 10 with different heights on the rotating disc 3 form a smooth transition path, reducing the bending friction of the cable.

[0049] A plurality of threaded holes are arranged on the two intermediate sections 1 at both ends, and a locking bolt 11 is threadedly connected in each threaded hole.

[0050] A plurality of arc-shaped sliding grooves 12 are further arranged on the body of the driving ring 6, and each locking bolt 11 slides in one of the sliding grooves 12.

[0051] When the supporting leg 5 is unfolded to the required angle, the locking bolt 11 is tightened to abut against the driving ring 6, so that the driving ring 6 is limited to continue to rotate, thereby fixing the position of the supporting leg 5;

[0052] The sliding cooperation between the locking bolt 11 and the sliding groove 12 allows the continuous adjustment of the rotation angle of the driving ring 6, and the quick locking at any angle is realized by tightening the bolt, so that the device is suitable for pipes of different diameters.

[0053] The movable end of the supporting leg 5 is provided with a foot pad 13.

[0054] The foot pad 13 can increase the effective contact area of the supporting leg 5 with the well wall, prevent the supporting leg 5 from slipping, and improve the stability of the device during use.

[0055] During use, the guide frame is placed into the cable well as a whole, the connecting units 2 between adjacent intermediate sections 1 are unfolded synchronously, the axial length of the guide frame is adjusted to adapt to the well depth;

[0056] The preassembled intermediate section 1, the supporting leg 5 and the driving ring 6 structure only need to be unfolded to complete the adaptation, and the construction process is simplified.

[0057] By rotating the driving ring 6 on the middle section 1, all the supporting legs 5 are expanded synchronously to the well wall direction through the control rod 7 on the driving ring 6, so that the supporting legs 5 end the mat foot 13 abuts against the well wall, and a stable support is formed,

[0058] The guide piece 4 on the rotating disc 3 of the middle section 1 guides the cable, the cable enters the annular channel formed by the middle section 1 through the guide piece 4, and the lower part of the cable enters the underground pipe gallery through the guide piece 4.
