Description

Technical Field

[0001] This invention relates to the field of pole-lifting devices, and more particularly to an automated pole-lifting device suitable for automatic assembly and disassembly at construction sites. The invention also discloses a splicing method for the automated pole-lifting device. Background Technology

[0002] In the construction of power transmission lines, a large number of high-voltage towers need to be built. High-voltage towers are generally assembled from several different types of building materials. The existing construction process for high-voltage towers is generally as follows: first, the foundation and tower feet are built on the ground, and then the tower body building materials are gradually assembled upwards. When the high-voltage tower is erected to a certain height, a lifting pole device is needed as an auxiliary hoisting tool to safely transport the various building materials to the erected height position.

[0003] During the use of the gantry crane, as the height of the high-voltage tower increases, the height of the gantry crane also needs to be continuously increased to ensure that the building materials can be lifted to the assembly position. When adding gantry crane sections, the two gantry crane sections need to be assembled and fixed by multiple connecting mechanisms. Due to the large number of connecting mechanisms, the height needs to be increased repeatedly throughout the construction process. In addition, after the high-voltage tower is completed, external tools and equipment are needed to disassemble the assembled gantry crane sections one by one. Therefore, the entire assembly and disassembly process is difficult to operate, the workload is heavy, the degree of automation is low, and it is not convenient to disassemble and assemble. Summary of the Invention

[0014] Preferably, the lower inner surface of the sliding groove has two symmetrically connected telescopic grooves. The lower end of the top section of the support rod and the lower end of the splicing section of the support rod are both provided with stabilizing mechanisms. The stabilizing mechanism includes a stabilizing clip slidably installed in the telescopic groove and two clearance slots. The end of the stabilizing clip away from the sliding groove passes through the telescopic groove and is fixedly installed with a second magnetic block.

[0015] The top end of the pole splicing section is fixedly installed with a docking ring body sleeved on the outside of the threaded column.

[0020] This invention also discloses a method for assembling an automated pole-mounting device suitable for automatic assembly and disassembly at construction sites, comprising the following steps:

[0021] 1) The top section 2 of the jib is pulled into the sliding groove 5 by the external traction mechanism and supported by the active lifting mechanism 13. Then, the jib splicing section 3 is lifted by the active lifting mechanism 13 and moved up along the stable support 4. After the top of the jib splicing section 3 rises to the designated position at the bottom of the sliding groove 5, the active lifting mechanism 13 stops running and the top section 2 of the jib stops rising.

[0022] 2) Move another boom splice section 3 onto the lifting component 83. Then, by extending the lifting component 83, the boom splice section 3 on it can be moved upward until it reaches the set position. The lifting component 83 stops extending, and at this time the locking component 85 releases the locking effect on the rotating drum 81.

[0023] 3) Then, the drive component 82 drives the rotating drum 81 to start rotating. At the same time, the lifting component 83 continues to extend, so that the threaded column 7 begins to connect with the threaded groove 6 until the two are fully assembled together, so that the stabilizing mechanism 9 is in the locked state, completing the assembly between the two splicing sections.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) By setting threaded columns and threaded grooves as connection structures, the splicing function between the top section of the gantry and the splicing section of the gantry or between two splicing sections of the gantry is realized, which replaces the traditional connection method that uses multiple connection structures to work together. Only one connection action is needed to complete the assembly process, which simplifies the splicing operation and helps to reduce the difficulty of splicing.

[0026] (2) In addition, the tightening mechanism drives the pole splicing section to rotate and move upward, so as to realize the automatic assembly function between the pole splicing section and the top section of the pole or between two pole splicing sections. This is conducive to quickly adjusting the height of the pole device, and thus facilitates the disassembly and assembly of the pole device. Attached Figure Description

[0040] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0041] Please refer to the following: Figures 1 to 12 The automated pole-lifting device applicable to automatic assembly and disassembly at construction sites includes: a base 1, a pole top section 2, and a pole splicing section 3. A stabilizing bracket 4 is fixedly installed on the top of the base 1. A sliding groove 5 is opened through the top of the stabilizing bracket 4. The bottom end of the pole top section 2 extends slidably from the top of the stabilizing bracket 4 into the sliding groove 5. Threaded grooves 6 are opened at the bottom ends of both the pole top section 2 and the pole splicing section 3. A threaded post 7 for matching the threaded groove 6 is fixedly installed at the top of the pole splicing section 3.

[0042] The stabilizer 4 has an active lifting mechanism 13 installed inside;

[0043] The base 1 is provided with a tightening mechanism 8 for automatically tightening the pole splicing section 3 with the pole top section 2. The bottom end of the pole splicing section 3 is movably engaged with the tightening mechanism 8. The tightening mechanism 8 includes a rotating cylinder 81 and a driving component 82 for driving the rotating cylinder 81 to rotate. The inside of the rotating cylinder 81 is provided with a lifting component 83 for clamping and lifting the bottom end of the pole splicing section 3.

[0044] To address the problems of difficult assembly, cumbersome operation, and inconvenience in assembling the pole splicing section 3, this invention solves the above problems by setting up this automated pole-holding device;

[0045] In use, the automated pole-lifting device of this invention first pulls the top section 2 of the pole into the sliding groove 5 via an external traction mechanism, and is supported by an active lifting mechanism 13. Then, the operator moves a pole-lifting splice section 3 onto the tightening mechanism 8, so that the bottom end of the pole-lifting splice section 3 is engaged with the installation position of the lifting component 83. The lifting component 83 then extends, causing the pole-lifting splice section 3 above it to move upwards until the threaded post 7 at the top of the pole-lifting splice section 3 aligns with the threaded groove 6 at the bottom end of the pole-lifting splice section 3 above it. The lifting component 83 then stops extending, and the device is then driven by the drive component 82. The rotating drum 81 begins to rotate, and at the same time, the lifting component 83 continues to extend, so that the threaded column 7 begins to connect with the threaded groove 6. Since the extension of the lifting component 83 is adapted to the displacement of the threaded column 7, it can ensure that the lower boom splice section 3 can be smoothly connected with the upper boom splice section 3 until the two are completely assembled together, and the operation of raising the boom device height is completed. If it is necessary to raise the height again, the above steps are repeated. The difference is that the lifting component needs to retract downward and reset before the next boom splice section 3 can be installed.

[0046] By setting threaded post 7 and threaded groove 6 as the connecting structure, the splicing function between the top section 2 of the pole and the splicing section 3 of the pole, or between two splicing sections 3 of the pole, is realized. This replaces the traditional connection method that uses multiple connecting structures. Only one connection action is needed during the assembly process, which simplifies the splicing operation and helps to reduce the splicing difficulty. The tightening mechanism 8 drives the splicing section 3 of the pole to rotate and move upward, so as to realize the automatic assembly function between the splicing section 3 of the pole and the top section 2 of the pole, or between two splicing sections 3 of the pole. This facilitates the quick adjustment of the height of the pole device, and makes it easier to disassemble and assemble the pole device.

[0047] As an embodiment of the present invention, a device groove 10 is provided on the top of the base 1, the bottom end of the rotating cylinder 81 is rotatably connected to the bottom wall of the device groove 10, and the top end of the rotating cylinder 81 rotates through the device groove 10 and passes through the top of the base 1.

[0048] As an embodiment of the present invention, the driving component 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, and the gear ring 822 is fixedly fitted on the bottom end of the rotating drum 81. The output end of the driving motor 821 is fixedly installed with a first gear 823 that meshes with the gear ring 822.

[0049] In order to enable the mast splicing section 3 to rotate and thread with the mast top section 2, a drive component 82 is set to drive the rotating drum 81 and the mast splicing section 3 to rotate. When the drive component 82 drives the rotating drum 81 to rotate, the drive motor 821 rotates, which causes the first gear 823 and the gear ring 822 to rotate together. The rotating drum 81 rotates synchronously with the gear ring 822, and drives the lifting component 83 and the mast splicing section 3 on the lifting component 83 to rotate together. Finally, the threaded column 7 can be tightened into the threaded groove 6.

[0050] As an embodiment of the present invention, the lifting component 83 includes a hydraulic cylinder 831 fixedly installed on the bottom wall of the rotating drum 81. The telescopic end of the hydraulic cylinder 831 is fixedly installed with a sliding clamp 832 that is slidably connected to the inner wall of the rotating drum 81. The top of the sliding clamp 832 is provided with a limiting groove 833 for placing the bottom end of the pole splicing section 3. The outer side of the rotating drum 81 is provided with an entry slot 84 that communicates with the limiting groove 833.

[0051] When the rotating drum 81 and the boom splicing section 3 are driven to rotate by the drive component 82, the height of the boom splicing section 3 will change after it is threadedly connected to the boom top section 2. Therefore, in order to ensure that the boom splicing section 3 and the boom top section 2 are assembled smoothly, the height of the boom splicing section 3 is adjusted synchronously by the lifting component 83. When the lifting component is in use, the operator installs the boom splicing section 3 into the sliding clamp 832 through the inlet 84. After installation, the hydraulic cylinder 831 extends, which can drive the sliding clamp 832 to move upward synchronously inside the rotating drum 81. At the same time, it can also drive the boom splicing section 3 on it to move upward to adapt to the height change during the assembly of the boom splicing section 3. This helps to ensure that the bottom end of the boom splicing section 3 is supported after assembly, thereby assisting in the automatic disassembly and assembly operation.

[0052] As an embodiment of the present invention, the tightening mechanism 8 further includes a locking component 85 for locking the position of the rotating drum 81. The locking component 85 includes two connecting plates 851 and two snap-fit ​​plates 852. The two connecting plates 851 are symmetrically fixedly installed on the outside of the rotating drum 81. The snap-fit ​​plates 852 are fixedly installed on the top of the base 1 at a position corresponding to the connecting plates 851. The connecting plates 851 have a movable groove 853 inside. The side of the movable groove 853 near the rotating drum 81 communicates with the inner wall of the rotating drum 81.

[0053] Specifically, a slide rod 854 is fixedly installed between the two inner sidewalls at the lower end of the movable groove 853. A sliding member 855 is slidably fitted on the outer side of the slide rod 854. The outer side of the sliding member 855 is slidably connected to the inner sidewall of the movable groove 853. A connecting spring 856 is fitted on the outer side of the slide rod 854, with both ends fixedly installed between the movable groove 853 and the sliding member 855. A snap-fit ​​groove 857 is provided on the side of the snap-fit ​​plate 852 near the connecting plate 851. The end of the sliding member 855 away from the rotating cylinder 81 slides through the connecting plate 851 and is slidably inserted into the snap-fit ​​groove 857. The end of the sliding member 855 near the rotating cylinder 81 slides through the movable groove 853 to the inner side of the rotating cylinder 81. A first inclined surface 858 is provided at the end of the sliding member 855 extending to the inner side of the rotating cylinder 81. A second inclined surface 859 is provided at the lower end of the sliding clamp 832, which slides and fits against the first inclined surface 858.

[0054] A first magnetic block 8510 is fixedly installed at the lower end of the sliding member 855, a first electromagnet 8511 is fixedly installed on one side of the inner wall of the movable groove 853 and is disposed opposite to the first magnetic block 8510, and a pad 8512 for providing support for the bottom of the raised sliding clamp 832 is fixedly installed at the top of the sliding member 855.

[0055] Since the rotating drum 81 is rotatably connected to the device slot 10, and the rotating drum 81 needs to bear most of the weight of the top section 2 of the support rod and the splicing section 3 of the support rod, the stability of the rotating drum 81 is difficult to guarantee when it is not rotating. Therefore, the above problem is solved by setting a locking component 85.

[0056] In this invention, if the height of the lever device needs to be increased during use, the operator first installs the lever splicing section 3 on the sliding clamp 832. During the upward movement of the sliding clamp 832 driven by the hydraulic cylinder 831, the center of gravity of the pressure exerted by the second inclined surface 859 on the first inclined surface 858 at the bottom of the sliding clamp 832 gradually shifts upward. Under the elastic force of the connecting spring 856, the sliding member 855 and the pad 8512 can be driven to slide horizontally synchronously with the sliding clamp 832, causing the end of the sliding member 855 to gradually separate from the locking groove 857. After the sliding clamp 832 drives the lever splicing section 3 to the docking position, the hydraulic cylinder 831 stops extending. Since the first inclined surface 858 and the second inclined surface 859 are still in contact, they obstruct the sliding member 855, thus preventing it from sliding further. At this time, the end of the sliding member 855 is completely separated from the locking groove 857, and the rotating drum 81 is no longer subject to the locking action, thereby releasing the locking action on the rotating drum 81. The rotating drum 81 can then drive the boom splicing section 3 to rotate under the driving action of the driving component 82. During the rotation of the rotating drum 81, the boom splicing section 3 will rise. By controlling the hydraulic cylinder 831 to continue to drive the sliding clamp 832 to move upward, the bottom end of the boom splicing section 3 will be adjusted and supported. Under the elastic force of the connecting spring 856, the sliding member 855 and the pad 8512 continue to slide. When the boom splicing section 3 is completed, the sliding clamp 832 stops extending, and the pad 8512 moves to the bottom end of the sliding clamp 832 and fits against the bottom of the sliding clamp 832, providing support for the sliding clamp 832 and reducing the burden on the hydraulic cylinder 831.

[0057] After the high-voltage tower is erected, when it is necessary to disassemble the pole splicing section 3, the pole splicing section 3 is first removed by rotating it using the tightening mechanism 8. At this time, the rotating drum 81 stops rotating, and the connecting plate 851 is aligned with the snap-fit ​​plate 852. Before the lifting component 83 moves the pole splicing section 3 down, the first electromagnet 8511 is energized and generates the same magnetism as the first magnetic block 8510, which in turn pushes the first magnetic block 8510, the sliding component 855, and the pad 8512 together away from the sliding component. The clamp 832 slides until the first inclined surface 858 on the sliding member 855 is in contact with the second inclined surface 859 on the sliding clamp 832. At this time, the hydraulic cylinder 831 drives the sliding clamp 832 to start moving down. Under the sliding and pressing action of the first inclined surface 858 and the second inclined surface 859, the sliding member 855 can be further pressed to slide until the sliding clamp 832 drops to the lowest position, so that the other end of the sliding member 855 is locked in the locking groove 857, completing the locking operation of the rotating drum 81.

[0058] By setting the locking component 85, on the one hand, it can be used to lock the position of the rotating drum 81. When the rotating drum 81 is not rotating, the sliding component 855 engages with the connecting plate 851, preventing the rotating drum 81 from rotating normally, thus achieving a locking effect. This helps to prevent the rotating drum 81 from rotating relative to the material during the lifting process, improving the stability of the top section 2 and the splicing section 3 of the lifting pole. On the other hand, when the sliding clamp 832 reaches its highest position, the sliding component 855 and the pad 8512 continue to slide, allowing the pad 8512 to slide to the bottom of the sliding clamp 832 to provide support. This helps to prevent the hydraulic cylinder 831 from bearing most of the weight alone, thus protecting the hydraulic cylinder 831 and improving the stability of the sliding clamp 832, providing better support for the top section 2 and the splicing section 3 of the lifting pole.

[0059] As an embodiment of the present invention, two telescopic grooves 11 are symmetrically connected on the inner surface of the lower end of the sliding groove 5. The lower end of the top section 2 of the support rod and the lower end of the splicing section 3 of the support rod are both provided with a stabilizing mechanism 9. The stabilizing mechanism 9 includes a stabilizing clip 91 slidably installed in the telescopic groove 11 and two clearance slots 98. The end of the stabilizing clip 91 away from the sliding groove 5 passes through the telescopic groove 11 and is fixedly installed with a second magnetic block 92. The two clearance slots 98 are symmetrically opened on the inner side wall of the sliding groove 5. The outer side of the stabilizing clip 91 is fitted with a support spring 93 with both ends fixed between the telescopic groove 11 and the stabilizing clip 91. Two second electromagnets 94 corresponding to the second magnetic block 92 are symmetrically fixedly installed on the side wall of the sliding groove 5.

[0060] The top of the pole splicing section 3 is fixedly installed with a docking ring 95 sleeved on the outside of the threaded post 7. Two locking holes 96 adapted to the stabilizing clip 91 are symmetrically opened on the outside of the docking ring 95. The end of the stabilizing clip 91 away from the second magnetic block 92 slides out of the telescopic groove 11 and engages with the locking hole 96. The bottom end of the pole splicing section 3 and the bottom end of the pole top section 2 are both provided with docking grooves 97 for docking with the docking ring 95. The top outer side of the docking ring 95 is set as a conical surface, and the end of the stabilizing clip 91 is set as an arc shape.

[0061] Since the top section 2 of the mast and the splicing section 3 of the mast are connected by threads, they may become loose during use. Therefore, in order to further improve the stability of the connection between the two, a stabilizing mechanism 9 is set to solve the above problem.

[0062] During the splicing process of the pole splicing section 3 and the pole top section 2, the threaded column 7 first enters the threaded groove 6, and then the docking ring 95 enters the docking groove 97. When the top of the docking ring 95 contacts the stabilizing clip 91, since the top of the docking ring 95 is conical and the end of the stabilizing clip 91 is arc-shaped, after the two contact, as the docking ring 95 moves upward, it can squeeze the stabilizing clip 91 into the telescopic groove 11 and at the same time squeeze the support spring 93 to contract, so that the top of the docking ring 95 can smoothly rotate through the stabilizing clip 91. When the locking hole 96 rotates to align with the stabilizing clip 91, the threaded column 7 also reaches the maximum tightening position. At this time, under the elastic force of the support spring 93, the stabilizing clip 91 can be locked in the locking hole 96, thereby locking the docking ring 95.

[0063] When it is necessary to disassemble the pole splicing section 3, since the second magnetic block 92 is aligned with the second electromagnet 94, the second electromagnet 94 can generate a magnetic force opposite to that of the second magnetic block 92 after being energized. This can attract the second magnetic block 92 and the stabilizing clip 91 to move together until the second magnetic block 92 and the second electromagnet 94 are in contact, which makes the stabilizing clip 91 completely separate from the clip hole 96, thereby releasing the locking effect on the docking ring 95. Then, the pole splicing section 3 can be disassembled by driving the rotating drum 81 to rotate.

[0064] By using the docking ring 95, the second electromagnet 94, and the stabilizing mechanism 9 in conjunction, the connection between the pole splicing section 3 and the pole top section 2 can be further strengthened. After the pole splicing section 3 and the pole top section 2 reach the assembly position, the stabilizing clip 91 can be engaged with the clip hole 96, thereby locking the docking ring 95 and the pole splicing section 3. This helps to prevent the pole splicing section 3 and the pole top section 2 from loosening and improves the stability of the connection. At the same time, the stabilizing mechanism 9 can be adjusted to the unlocked state by using the magnetic force of the second electromagnet 94, realizing the automatic locking and unlocking function between the pole splicing section 3 and the pole top section 2. This achieves automated assembly during the assembly process, thereby reducing the workload of workers and speeding up the assembly and disassembly process.

[0065] As an embodiment of the present invention, the stable support 4 has an internal mounting groove 12, and the active lifting mechanism 13 is disposed in the mounting groove 12. The active lifting mechanism 13 includes a rotating motor 131 and two rotating shafts 132 symmetrically mounted on both sides of the top section 2 of the support pole. The two ends of the rotating shafts 132 are respectively fixedly mounted with a second gear 133 and a third gear 134, and the two third gears 134 mesh with each other. The rotating motor 131 is fixedly mounted inside the mounting groove 12, and the output end of the rotating motor 131 is fixedly connected to one side of one of the third gears 134. The top section 2 of the support pole and the splicing section 3 of the support pole are provided with multiple uniformly linearly arranged tooth grooves 135 on both sides corresponding to the second gear 133. The second gear 133 meshes with the tooth grooves 135 on the side of the top section 2 of the support pole.

[0066] When adjusting the height of the pole-lifting device, if the number of pole-lifting splice sections 3 is large, the required external traction force will increase. Therefore, in order to reduce the pressure on the external traction mechanism to drive the pole-lifting device to move upward, the above function is achieved by setting an active lifting mechanism 13. When the active lifting mechanism 13 is in use, the process of adding pole-lifting splice sections 3 is required. The external traction mechanism pulls the top section 2 of the pole and the pole-lifting splice section 3 upward together. At the same time, by rotating the motor 131, the two third gears 134 can rotate together, and the two rotating shafts 132 and the two second gears 133 can rotate together. Since the second gear 133 meshes with the tooth groove 135, the rotation of the second gear 133 can generate an upward thrust on the tooth groove 135, thereby assisting the pole-lifting splice section 3 to move upward. After reaching the lifting height, the external traction mechanism and the rotating motor 131 stop running, while the pole-lifting splice section 3 remains stationary.

[0067] By setting up the active lifting mechanism 13, on the one hand, it can assist the pole splicing section 3 to move up and down, which helps to reduce the driving burden of the external traction mechanism. Under dual-power drive conditions, the lifting and lowering action of the pole splicing section 3 is easier and smoother. On the other hand, through the meshing action between the second gear 133 and the tooth groove 135, the connection between the pole splicing section 3 and the stabilizing bracket 4 can be enhanced, making the sliding relationship between the two more reliable. This helps to improve the connection stability between the stabilizing bracket and the pole splicing section 3, making it safer during the lifting and lowering process and helping to avoid large-scale shaking.

[0068] As an embodiment of the present invention, a traction pulley device 14 is fixedly installed at the top of the pole top section 2, and a guide pulley 15 is fixedly installed on the legs of the stabilizing bracket 4.

[0069] The traction pulley device 14 and the guide pulley 15 are connected by a rope drive and are used to connect with an external traction mechanism to complete the lifting operation of building materials.

[0070] In one embodiment of the present invention, both the top section 2 of the pole and the splicing section 3 of the pole are quadrangular prisms, and the four prism faces of the top section 2 of the pole and the splicing section 3 of the pole overlap accordingly.

[0071] As an embodiment of the present invention, the top of the base 1 is evenly circumferentially distributed with a plurality of positioning holes 16. When fixing the base 1, positioning pins are used to pass through the positioning holes 16 and fix it to the ground.

[0072] The working principle of the automated pole-holding device for automatic assembly and disassembly at construction sites provided by this invention is as follows:

[0073] Step 1: When it is necessary to continue assembling the pole splicing section 3 to increase the height of the pole device, first pull the top section 2 of the pole into the sliding groove 5 through the external traction mechanism, support it through the active lifting mechanism 13, and then lift the pole splicing section 3 along the stable support 4 through the active lifting mechanism 13. After the top of the pole splicing section 3 rises to the designated position at the lower end of the sliding groove 5, the active lifting mechanism 13 stops running, and the top section 2 of the pole stops rising.

[0074] Step 2: Move another boom splice section 3 onto the lifting component 83. The lifting component 83 then extends to move the boom splice section 3 upward until it reaches the set position. The lifting component 83 then stops extending, and the locking component 85 releases its locking effect on the rotating drum 81.

[0075] Step 3: Next, drive the rotating drum 81 to start rotating through the drive component 82. At the same time, the lifting component 83 continues to extend, so that the threaded column 7 begins to connect with the threaded groove 6 until the two are fully assembled together, which makes the stabilizing mechanism 9 locked, completing the assembly between the two splicing sections.

[0076] Step 4: When disassembling the splicing section, first use the tightening mechanism 8 to rotate the splicing section to disengage the connection. Then, use the tightening mechanism 8 to move the disengaged pole splicing section 3 down. Then, remove the pole splicing section 3. Next, use the active lifting mechanism to drive the next pole splicing section 3 down to the contact position with the tightening mechanism 8, and then begin disassembling the pole splicing section 3. Repeat this operation.

[0077] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by the appended claims and their equivalents is defined.
