[0033] Support units 9 are installed on the side walls of the bottom support section 1, the top mounting section 2, and several intermediate sections 3. Each of the bottom support section 1, the top mounting section 2, and the several intermediate sections 3 includes two steel frames 10, and multiple square steel columns 11 and multiple polygonal steel columns 12 are fixedly arranged between the two steel frames 10. Support units 9 are installed on the side walls of each square steel column 11. Support units 9 include steel sleeves 91 that are fixedly inserted into the side walls of the square steel columns 11.

The movable slide 94 has an end cap 95 fixedly connected to the end of the steel sleeve 91, and a return spring 96 is fixedly installed between the end cap 95 and the support block 92. The side wall of the support block 92 has an inclined slope. When the movable seat 5 and the pad 84 move vertically, they push the support block 92 horizontally by the slope. During the upward movement of the movable seat 5, it is still necessary to use external hoisting equipment for auxiliary limiting (for example, by using ropes to pull it obliquely at the top of the antenna to limit its left and right swaying, etc., and by releasing the rope appropriately when the antenna is rising to avoid affecting the antenna's ascent), to ensure the safety of the high-altitude antenna installation.

[0034] The lower steel frame 10 of the bottom support section 1 has a connecting column 14 fixed inside, and each pad 84 is set above the connecting column 14 on the same side. The upper steel frame 10 of the top mounting section 2 has a mounting frame 15 fixed inside. The end faces of the mounting frame 15 and the movable seat 5 are pre-drilled with threaded holes, which can facilitate the pre-fixing of the movable seat 5 and ensure the accuracy of installation.

[0035] Several oil baffles 16 are provided below the two piston plates 133, and multiple oil holes 17 are provided on the side wall of the oil baffles 16. An oil passage groove 18 is provided at the bottom of the partition plate 132. By utilizing the viscous resistance of hydraulic oil, vibration energy can be dissipated to a certain extent, thereby improving the wind resistance and stability of the mast and antenna.

[0036] Each oil baffle 16 is provided with a set of connecting blocks 19 above it, and the connecting blocks 19 are fixed to the bottom of the piston plate 133. The two connecting blocks 19 in the same set are rotatably connected to the oil baffle 16, and a torsion spring 20 is provided between the oil baffle 16 and the connecting blocks 19. Since the piston plate 133 needs to move down when the movable seat 5 is lifted, the oil baffle 16 will not affect the normal downward movement of the piston plate 133 because the oil baffle 16 and the connecting blocks 19 rotate at this time.

[0037] The operation principle of the application is described as follows: the antenna is pre-installed on the antenna mounting seat 4 on the ground, then a plurality of intermediate sections 3 are assembled with the bottom supporting section 1 and the top mounting section 2 in sequence and fixed by welding or the like, then hoisted to the top of the TV tower, the bottom supporting section 1 is fixed at the preset mounting position on the top of the tower, then the electric push rod 134 controller is connected with the reserved interface on the movable seat 5, the electric push rod 134 controller is connected with the external power supply circuit, then the electric push rod 134 controller is started;

[0038] The electric push rod 134 controller controls the electric push rod 134 to perform the extension action, the electric push rod 134 pushes the corresponding piston plate 133 to move downward, the piston plate 133 extrudes the hydraulic oil below, under the extrusion action, the hydraulic oil enters the inside of each cylinder body 81 through each oil supply pipe 135, under the oil pressure of the hydraulic oil, the cylindrical piston 82 in the inside of each cylinder body 81 moves relative to the cylinder body 81, since the gasket plate 84 of the telescopic column 83 abuts against the connecting column 14 in the bottom supporting section 1 at the beginning, at this time, the gasket plate 84 cannot move, so the cylinder body 81 moves upward relative to the telescopic column 83, thereby pushing the movable seat 5 to move upward along the guide slide strip 6, when the movable seat 5 moves to the upper supporting block 92, the movable seat 5 extrudes the slope surface on the side of the supporting block 92, thereby pushing the supporting block 92 to move horizontally, and when the movable seat 5 passes the supporting block 92, under the action of the reset spring 96, the supporting block 92 moves back to the reset position, at this time, the travel switch on the electric push rod 134 feeds back the electric signal to the electric push rod 134 controller, the electric push rod 134 controller controls the electric push rod 134 to stop the extension action and controls the electric push rod 134 to start the return movement, at this time, since the pressure applied by the piston plate 133 to the hydraulic oil disappears, under the action of the supporting spring 85, each cylindrical piston 82 moves back to the reset position, the hydraulic oil flows back to the cylinder box 131, at the same time, since the movable seat 5 is on the upper side of the supporting block 92 at this time, under the action of the gravity, the supporting block 92 supports the movable seat 5, and the gasket plate 84 moves upward with the telescopic column 83 to the reset position, when the gasket plate 84 moves to the corresponding supporting block 92, the gasket plate 84 also extrudes the slope surface on the side of the supporting block 92, thereby pushing the supporting block 92 to move horizontally, and when the gasket plate 84 passes the supporting block 92, under the action of the reset spring 96, the supporting block 92 moves back to the reset position, at this time, the supporting block 92 is below the gasket plate 84, at this time, the electric push rod 134 moves back to the reset position, the travel switch of the electric push rod 134 feeds back the electric signal to the electric push rod 134 controller, the electric push rod 134 controller controls the electric push rod 134 to perform the extension action again, by the same principle, the cylinder body 81 and the cylindrical piston 82 move relative to each other again, and since the gasket plate 84 is temporarily supported by the supporting block 92 at this time, the movable seat 5 continues to move upward, and the cycle is repeated, so that the height of the movable seat 5 is continuously increased, thereby driving the antenna to extend upward from the mast;

[0039] With the upward movement of the movable seat 5, the movable seat 5 will be in contact with the mounting frame 15 at the top mounting joint 2, at this time, the installer temporarily closes the electric push rod 134 controller, then the installer locks the mounting frame 15 and the movable seat 5 together through bolts and threaded holes on the mounting frame 15 and the movable seat 5, ensures the positional accuracy of the movable seat 5, then the mounting frame 15 and the movable seat 5 are secondarily fixed by welding or other methods, to ensure the firmness of the installation of the movable seat 5;

[0040] After the movable seat 5 and the mounting frame 15 are fixed, the installer starts the electric push rod 134 controller to control the return of each electric push rod 134 to reset, at this time, the hydraulic oil flows back to the cylinder box 131 inside, when the mast and the antenna encounter strong wind at high altitude in the subsequent process, the mast and the antenna will vibrate under the action of strong wind, the hydraulic oil in the cylinder box 131 will flow relative to the cylinder box 131, the hydraulic oil on both sides of the partition plate 132 needs to pass through the oil passage 18, and the hydraulic oil will be blocked by the oil baffle 16, by using the viscous resistance of the hydraulic oil, the vibration energy can be dissipated to a certain extent, so as to improve the wind resistance of the mast and the antenna, and the stability is better (wherein, since the piston plate 133 needs to move downward when lifting the movable seat 5, at this time, since the oil baffle 16 rotates with the connecting block 19, the oil baffle 16 will not affect the normal downward movement of the piston plate 133).

[0041] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
