A transmission mechanism for driving the lifting column 2 to lift relative to the base 1 is installed inside the power box 4; an adjusting mechanism for controlling the locking and releasing of the fixed seat 3 is installed inside the base 1 and the lifting column 2

[0026] By setting a fixing base 3 at the top end of the lifting post 2, the cable can be clamped and fixed, preventing the cable from slipping relative to the fixing base 3 during the process of lifting the cable, and the cable can be supported and lifted on the premise of ensuring the laying length of the cable, without the need to adjust the cable length again after the cable is supported and lifted; the adjusting mechanism for controlling the loosening and fastening of the fixing base 3 is installed at the bottom of the base 1, which is convenient for personnel to control the fixing base 3 to loosen the fastening of the cable on the ground after the cable laying is completed, improving convenience.

[0027] The specific structure of the transmission mechanism is as Figure 2 shown. The transmission mechanism includes a main shaft 5 rotatably installed inside the power box 4 and a rack 9 vertically and fixedly installed on the lifting post 2. A gear 6 is synchronously sleeved on the main shaft 5, and the gear 6 is meshed with the rack 9. A handwheel 8 is also fixedly sleeved at the end of the main shaft 5;

[0028] Among them, a locking mechanism 7 is also installed on the main shaft 5. The locking mechanism 7 is fixedly installed on the power box 4. The locking mechanism 7 adopts an electromagnetic braking device. When it is necessary to rotate the handwheel 8, the locking mechanism 7 is controlled to be energized. At this time, the locking mechanism 7 releases the rotation restriction on the main shaft 5; after the lifting post 2 is raised to the required height, the locking mechanism 7 is controlled to be powered off. At this time, the locking mechanism 7 locks the main shaft 5 to prevent the lifting post 2 from sliding down under its own gravity.

[0029] Furthermore, universal casters are installed at the bottom of the base 1, and a locking mechanism is provided on the universal casters; by setting the universal casters, it is convenient to move the base 1 and the connection structures such as the lifting post 2 as a whole; at the same time, the base 1 can also be towed and moved by a tractor, greatly saving manpower.

[0030] Specifically, the fixing base 3 includes a support plate 10 fixedly installed on the lifting post 2. A through hole for the cable to pass through is provided in the middle of the support plate 10. At least three groups of pin shafts 11 are arranged in a circumferential array on the support plate 10 with the axis of the through hole as the axis. A pressing piece 12 is rotatably installed on each group of pin shafts 11;

[0031] Specifically, the pressing piece 12 is in the shape of a crowbar. The rotation axis of the pressing piece 12 is close to the corner of the pressing piece 12. An installation ring 13 is fixedly arranged on the support plate 10. The installation ring 13 is coaxial with the through hole. A number of groups of movable slots 14 are arranged in a circumferential array on the installation ring 13 for the pressing piece 12 to freely pass through. A turntable 15 is rotatably installed coaxially on the installation ring 13. A number of groups of strip-shaped slots 17 are respectively arranged on the turntable 15 corresponding to a number of groups of pressing pieces 12. Each group of strip-shaped slots 17 is along the radial direction of the turntable 15. A guide post 16 is fixedly arranged at the bending part of each group of pressing pieces 12. A number of groups of guide posts 16 are respectively slidably installed in a number of groups of strip-shaped slots 17;

[0032] Specifically, how to drive the turntable 15 to rotate along its own axis, teeth are arranged on the circumferential outer wall of the turntable 15, a transmission shaft 18 is rotatably installed on the lifting column 2, and the transmission shaft 18 rises and falls synchronously with the lifting column 2, and the end of the transmission shaft 18 extending above the lifting column 2 is coaxially fixed with a toothed disc 19, and an annular tooth 20 is coaxially arranged on the end surface of the toothed disc 19, and the annular tooth 20 is meshed and connected with the teeth on the circumferential outer wall of the turntable 15;

[0033] In this embodiment, the transmission shaft 18 is first driven by the adjustment mechanism at the bottom of the base 1 to rotate counterclockwise by a certain angle, so that the several groups of pressing plates 12 are all turned to the outside of the mounting ring 13, and the cables are passed through the mounting ring 13. Then, the transmission shaft 18 is driven by the adjustment mechanism to rotate clockwise by a certain angle, so that the several groups of pressing plates 12 are synchronously extended into the mounting ring 13, and the cables are simultaneously compressed and fixed; when the cables need to be loosened, the transmission shaft 18 is driven to rotate counterclockwise to release the compression of the several groups of pressing plates 12 on the cables.

[0034] Furthermore, the specific structure of the regulating mechanism is as follows Figure 3 and Figure 4 As shown, a support shaft 21 is rotatably mounted at the bottom of the base 1, the support shaft 21 is coaxial with the transmission shaft 18, a plum blossom shaft 22 is coaxially fixedly arranged on the support shaft 21, a plum blossom groove 23 is coaxially penetrated on the transmission shaft 18, the transmission shaft 18 is slidably mounted on the plum blossom shaft 22 by relying on the plum blossom groove 23, and the transmission shaft 18 rotates synchronously with the plum blossom shaft 22;

[0035] A worm wheel 24 is coaxially mounted on the support shaft 21, and an adjusting shaft 25 is rotatably mounted on the bottom of the base 1. A worm 26 is coaxially sleeved on the adjusting shaft 25, and the worm 26 is meshed with the worm wheel 24 for transmission.

Under the transmission action of the worm gear 24 and the worm 26, the support shaft 21, the plum blossom shaft 22 and the transmission shaft 18 are driven to rotate, thereby realizing the control of the fixed seat 3. By relying on the plum blossom groove 23 and the plum blossom shaft 22 to realize the synchronous rotation of the transmission shaft 18 and the support shaft 21, the lifting column 2 can still drive the transmission shaft 18 to rotate through the support shaft 21 after moving relative to the base 1, thereby improving convenience.

[0037] A cable support frame for line laying of the present invention has the following features during operation:

[0038] First, manually rotate the rocker 27 to drive the adjustment shaft 25 to rotate along its own axis. Under the transmission action of the worm gear 24 and the worm 26, drive the support shaft 21, the plum blossom shaft 22 and the transmission shaft 18 to rotate counterclockwise by a certain angle, drive the turntable 15 to rotate clockwise, and under the guidance of the strip groove 17 and the guide column 16, move the several groups of pressing plates 12 to rotate clockwise along their own rotation axes respectively, so that the several groups of pressing plates 12 are all rotated to the outside of the mounting ring 13, pass the cables through the mounting ring 13, and then manually rotate the rocker 27 to rotate, drive the transmission shaft 18 to rotate clockwise by a certain angle, drive the turntable 15 to rotate counterclockwise, and under the guidance of the strip groove 17 and the guide column 16, move the several groups of pressing plates 12 to rotate counterclockwise along their own rotation axes respectively, so that the several groups of pressing plates 12 are synchronously extended into the mounting ring 13, and the cables are synchronously pressed and fixed;

[0039] Afterwards, the locking mechanism 7 is powered on by controlling the locking mechanism 7. At this time, the locking mechanism 7 releases the rotation restriction on the main shaft 5. By manually rotating the hand wheel 8, the gear 6 drives the rack 9 to rise and fall, thereby adjusting the height of the lifting column 2 relative to the base 1. When the lifting column 2 is adjusted to a suitable height, the locking mechanism 7 is powered off by controlling the locking mechanism 7 to lock the main shaft 5 to prevent the lifting column 2 from sliding downward under its own gravity.
