The bottom ends are all provided with threaded grooves 6, and the top of the splicing section 3 of the holding pole is fixedly installed with a threaded column 7 for matching with the threaded grooves 6;

An active lifting mechanism 13 is installed inside the stabilizing support 4;

As an embodiment of the present invention, a device groove 10 is provided on the top of the base 1, and the bottom end of the drum 81 is rotatably connected with the bottom wall of the device groove 10. the top of.

As an embodiment of the present invention, the driving part 82 includes a driving motor 821 and a gear ring 822, the driving motor 821 is fixedly installed on the bottom wall of the device groove 10, the gear ring 822 is fixedly sleeved on the bottom end of the drum 81, and the driving motor The output end of 821 is fixedly installed with a first gear 823 meshing with ring gear 822 .

In order to be able to drive the pole-holding splicing section 3 to be rotated and threadedly spliced with the pole-holding top section 2, the rotating cylinder 81 and the pole-holding splicing section 3 are driven to rotate by setting the driving part 82. When the driving part 82 drives the rotating cylinder 81 to rotate, the drive motor 821 rotates, the first gear 823 and the gear ring 822 can rotate together, and the drum 81 rotates synchronously with the gear ring 822, and drives the lifting part 83 and the pole-holding splicing section 3 on the lifting part 83 to rotate together, and finally can make The threaded post 7 can be screwed into the threaded groove 6 .

As an embodiment of the present invention, the lifting part 83 includes a hydraulic cylinder 831 fixedly installed on the bottom wall of the rotating drum 81, and the telescopic end of the hydraulic cylinder 831 is fixedly installed with a sliding clamp seat 832 slidingly connected with the inner wall of the rotating drum 81. The top of the seat 832 is provided with a limiting groove 833 for placing the bottom end of the pole-holding splicing section 3 , and the outer side of the drum 81 is provided with an entry slot 84 communicating with the limiting groove 833 .

When the rotating drum 81 and the pole-holding splicing section 3 are driven by using the driving part 82, since the pole-holding splicing section 3 is screwed with the pole-holding top section 2, the height of the pole-holding splicing section 3 will change, so in order to ensure that the pole-holding The splicing section 3 and the top section 2 of the pole are assembled smoothly, and the height of the splicing section 3 of the pole is adjusted synchronously by setting the lifting part 83. When the lifting part is in use, the staff installs the splicing section 3 of the pole on the sliding clip through the entry slot 84 In the seat 832, after the installation is completed, the hydraulic cylinder 831 is extended, which can drive the sliding clamp seat 832 to move up synchronously on the inner side of the drum 81, and at the same time can drive the pole-holding splicing section 3 on it to move up to adapt to the pole-holding splicing section 3 The height change during assembly is beneficial to ensure that the bottom end of the pole-holding splicing section 3 is supported after assembly, and then assists in completing the automatic disassembly operation.

As an embodiment of the present invention, the screwing mechanism 8 also includes a locking part 85 for locking the position of the drum 81. The locking part 85 includes two connecting plates 851 and two clamping plates 852. The two connecting plates 851 is symmetrically and fixedly installed on the outer side of the drum 81, and the clamping plate 852 is fixedly installed on the top of the base 1 at a position corresponding to the connecting plate 851. The inside of the connecting plate 851 is provided with a movable groove 853, and the movable groove 853 is close to the bottom of the rotating drum 81. One side communicates with the inner wall of the drum 81;

Specifically, a sliding bar 854 is fixedly installed between the two inner side walls of the lower end of the movable groove 853, and the outer side of the sliding bar 854 is slidingly sleeved with a sliding piece 855, and the outer side of the sliding piece 855 is slidingly connected with the inner side wall of the movable groove 853, and the sliding bar 854 There is a connection spring 856 with both ends fixedly installed between the movable groove 853 and the sliding piece 855 on the outer side of the sleeve. The side of the clamping plate 852 close to the connecting plate 851 is provided with a clamping groove 857. The side of the sliding piece 855 away from the drum 81 One end slides through the connecting plate 851 and then slides and plugs into the clamping groove 857. The end of the slider 855 close to the drum 81 slides through the movable groove 853 to the inner side of the drum 81, and the end of the slider 855 extending to the inner side of the drum 81 is set. There is a first inclined surface 858, and the lower end of the sliding clamp seat 832 is provided with a second inclined surface 859 that slides and fits with the first inclined surface 858;

The lower end of the slider 855 is fixedly equipped with a first magnetic block 8510, and one side of the movable groove 853 inner wall is fixedly installed with a first electromagnet 8511 opposite to the first magnetic block 8510. The pads 8512 for support are provided at the bottom of the rear slide holder 832 .

Since the rotating drum 81 is rotatably connected with the device groove 10, and the rotating drum 81 needs to bear most of the weight of the pole top section 2 and the pole splicing section 3, when the rotating drum 81 is in a non-rotating condition, the rotating The stability of the barrel 81 is difficult to be guaranteed, so the above-mentioned problem is solved by setting a locking part 85;

In the present invention, if the locking member 85 needs to increase the height of the pole-holding device during use, the staff first installs the pole-holding splicing section 3 on the sliding clamping seat 832, and then drives the sliding clamping seat 832 on the hydraulic cylinder 831 During the moving process, the center of gravity of the pressing force of the second inclined surface 859 on the bottom of the sliding clamp seat 832 against the first inclined surface 858 gradually moves upwards, and under the action of the elastic force of the connecting spring 856, the sliding member 855 and the spacer 8512 can be driven to follow the sliding clamp. The seat 832 slides horizontally synchronously, so that the end of the slider 855 is gradually separated from the engaging groove 857. After the sliding clip seat 832 drives the pole splicing section 3 to reach the docking position, the hydraulic cylinder 831 stops extending. The two slopes 859 are still in the bonding state, which hinders the sliding part 855, so the sliding part 855 does not continue to slide. At this time, the end of the sliding part 855 is also completely separated from the engagement groove 857, and the rotating cylinder 81 is on the other side. No longer subject to the clamping effect, and then the locking effect on the rotating drum 81 is released, and the rotating drum 81 can drive the pole-holding splicing section 3 to rotate under the driving action of the driving part 82. During the rotation of the rotating drum 81, the pole-holding The splicing section 3 will rise, and the control hydraulic cylinder 831 will continue to drive the sliding clamp seat 832 to move up to adjust and support the bottom end of the splicing section 3 of the pole, and under the elastic force of the connecting spring 856, the sliding member 855 and the spacer 8512 will continue to move upward. Sliding, when the pole splicing section 3 is spliced, the sliding clamping seat 832 stops elongating at this time, and the spacer 8512 just moves to the bottom of the sliding clamping seat 832, and fits with the bottom of the sliding clamping seat 832, forming a sliding The clamp seat 832 provides support to reduce the burden on the hydraulic cylinder 831;

After the high-voltage iron tower is built, when it is necessary to disassemble the pole-holding splicing section 3, the pole-holding splicing section 3 is first rotated and removed by the tightening mechanism 8. At this time, the rotating drum 81 no longer rotates, and just makes the connecting plate 851 and the clamping joint The plates 852 are aligned, and before the elevating part 83 drives the pole splicing section 3 to move down, the first electromagnet 8511 starts to be energized, and generates the same magnetism as the first magnetic block 8510, thereby pushing the first magnetic block 8510 and the sliding part 855 Slide together with the spacer 8512 in the direction away from the sliding clamp seat 832 until the first inclined surface 858 on the sliding member 855 fits with the second inclined surface 859 on the sliding clamp seat 832. At this time, the hydraulic cylinder 831 drives the sliding clamp seat 832 to start Moving down, under the action of sliding and pressing on the first slope 858 and the second slope 859, the sliding member 855 can be further squeezed to slide until the sliding clamp seat 832 drops to the lowest position, just so that the other end of the sliding member 855 is clamped on the clip. In the connection groove 857, the locking operation of the drum 81 is completed;

By setting the locking member 85, on the one hand, it can be used to lock the position of the rotating drum 81. When the rotating drum 81 is in a non-rotating state, the sliding member 855 is engaged with the connecting plate 851, so that the rotating drum 81 cannot rotate normally, and then It plays a locking role, which is beneficial to avoid the relative rotation of the drum 81 during the lifting of building materials by the pole holding device, and can improve the stability of the top section 2 of the pole holding pole and the splicing section 3 of the pole holding pole; When the seat 832 reaches the highest position, the sliding member 855 and the cushion block 8512 continue to slide, so that the cushion block 8512 slides to the bottom position of the sliding clamp seat 832 to provide support for it, which is beneficial to avoid the hydraulic cylinder 831 from bearing most of the gravity alone, thereby The hydraulic cylinder 831 plays a certain protective role, and is conducive to improving the stability of the sliding clamp seat 832, and better provides support for the pole top section 2 and the pole splicing section 3.

As an embodiment of the present invention, the inner surface of the lower end of the sliding groove 5 is symmetrically connected with two telescopic grooves 11, and the lower end of the pole top section 2 and the lower end of the pole splicing section 3 are both provided with a stabilizing mechanism 9. The stabilizing mechanism 9 includes The stable clip 91 and two give way slots 98 that are slidably installed in the telescopic groove 11, the end of the stable clip 91 away from the sliding groove 5 is penetrated through the telescopic groove 11 and then fixedly installed with a second magnetic block 92, two The pass groove 98 is symmetrically opened on the inner side wall of the slide groove 5, and the outer side of the firm clip 91 is provided with a support spring 93 with two ends fixed between the telescopic groove 11 and the firm clip 91, and the slide groove 5 is symmetrical on the side wall. Two second electromagnets 94 corresponding to the second magnetic block 92 are fixedly installed;

The top of the pole splicing section 3 is fixedly installed with a docking ring body 95 sleeved on the outside of the threaded column 7, and the outside of the docking ring body 95 is symmetrically provided with two clamping holes 96 that are compatible with the stable clamp 91. The end of 91 away from the second magnetic block 92 slides and extends out of the telescopic slot 11 and then engages with the clamping hole 96. The bottom end of the splicing section 3 of the pole and the bottom end of the top section 2 of the pole are provided with a joint for docking with the docking ring 95. The butt joint groove 97, the outer top end of the butt joint ring body 95 is set as a conical surface, and the end of the stabilizing clip 91 is set as an arc shape.

Since the pole top section 2 and the pole splicing section 3 are threadedly connected, loosening may occur during use. Therefore, in order to further improve the stability of the connection between the two, a stabilizing mechanism 9 is provided to solve the above problems;

During the splicing process of the pole-holding splicing section 3 and the pole-holding top section 2, the threaded column 7 first enters the threaded groove 6, and then the docking ring body 95 enters the docking groove 97, and contacts the stable clip 91 at the top of the docking ring body 95 At the same time, since the top of the docking ring body 95 is conical, and the end of the stabilizing clip 91 is arc-shaped, after the two are in contact, as the docking ring body 95 moves up, the stabilizing clip 91 can be extruded toward the telescopic slot 11. The inner contraction, and at the same time the extrusion support spring 93 shrinks, so that the top of the docking ring body 95 can smoothly rotate through the stable clamp 91, when the clamp hole 96 rotates to align with the stable clamp 91, and the threaded column 7 just reaches the maximum rotation. Tight position, at this time, under the elastic force of the support spring 93, the stable clip 91 can be clipped in the clip hole 96, and then the butt ring body 95 can be locked;

And when needing to disassemble the pole-holding splicing section 3, now because the second magnetic block 92 is aligned with the second electromagnet 94, the magnetic force opposite to the second magnetic block 92 can be produced after the second electromagnet 94 is energized, and then It can attract the second magnetic block 92 and the stable clip 91 to move together until the second magnetic block 92 is attached to the second electromagnet 94, which just makes the stable clip 91 completely separate from the clip hole 96, thereby releasing the docking ring 95, and then the pole splicing section 3 can be disassembled by driving the rotating drum 81 to rotate;

By arranging the docking ring body 95, the second electromagnet 94, and the stabilizing mechanism 9 to be used together, it can be used to further increase the connection firmness between the splicing section 3 of the pole and the top section 2 of the pole. After the top section 2 arrives at the assembly position, the stabilizing clip 91 can be snapped into the clamping hole 96, thereby locking the docking ring body 95 and the pole splicing section 3, which is beneficial to prevent the pole splicing section 3 from colliding with the pole. The top section 2 is loose, which improves the stability of the connection between the two. At the same time, the magnetic force of the second electromagnet 94 can be used to adjust the stabilization mechanism 9 to the unlocked state, realizing the alignment between the splicing section 3 and the top section 2 of the pole.
