Description

Technical Field

[0001] The invention relates to the field of electric pole holding, and in particular to a step beam hydraulic propulsion sleeve structure for the pole holding. Background Art

[0002] When adding sections to a power mast, the mast tower must be raised to a height greater than one standard section, and then the new standard section must be introduced and docked with the standard section of the mast tower. Before raising the existing standard section, the step beam of the jacking platform must be manually raised. The hydraulic pump station then activates the lifting cylinder and confirms that the step beam of the frame is in contact with the jacking position (step) of the standard section before the raising and docking operations can begin. When raising the next standard section, the step beam must be manually flipped, making the operation at high altitude and cumbersome. Similarly, when removing the standard section of the power mast and lowering it, the same problem arises.

[0003] The traditional standard section lifting can only be introduced from the front. During the process of introducing and pulling out the standard section, it is not convenient to operate due to the limitation of direction.

[0004] The traditional introduction of standard sections requires the introduction trolley to be loaded with the introduced standard sections until they are assembled with the tower body. The hydraulic cylinder has cumbersome movements during the entire process of lifting and lowering the sections. There is a possibility that the worker may operate the hydraulic cylinder to lower too much and crush the introduction trolley. Summary of the Invention

[0047] Example 1

[0048] like Figure 1-3 As shown, a step beam hydraulic propulsion frame structure for holding a pole includes a lifting platform 1, a lower frame beam 2, an upper frame beam 3, a lifting hydraulic device 4, a step beam hydraulic propulsion device 5, and an underframe foundation assembly 6;

[0049] Among them, the lower frame beam 2 is assembled on the chassis foundation assembly 6, and the standard sections are introduced and led out on both sides thereof;

[0050] The upper frame beam 3 is arranged on the lower frame beam 2, and the entire sleeve is rigidly connected to the ground. The setting of the upper frame beam 3 can ensure the verticality of the tower body during the jacking process, and ensure that the tower body is not easy to overturn during the jacking process;

[0051] The jacking hydraulic device 4 has one end connected to the underframe foundation assembly 6, driving the jacking platform 1 to jack up or down;

[0052] The jacking platform 1 is arranged on the outer periphery of the sleeve frame and connected to the other end of the jacking hydraulic device 4 to ensure the installation space requirement of the step beam hydraulic propulsion device 5, including two sets of guide seat groups 113 consisting of two guide seats;

[0053] At least two step beam hydraulic propulsion devices 5 are symmetrically assembled on the jacking platform 1 and can be pushed out or retracted horizontally along the standard section direction, including:

[0054] Horizontal propulsion cylinder 51, whose cylinder body is connected to the jacking platform 1;

[0055] The step beam 52 is provided with a step beam connecting lug 521 connected to the piston rod of the horizontal propulsion cylinder 51;

[0056] The horizontal propulsion cylinder 51 drives the step beam 52 to move between the two guide seats of the guide seat group 113;

[0057] The track 7 is introduced and connected with the lower frame beam 2.

[0058] The present invention drives the step beam 52 by horizontally propelling the oil cylinder 51, and does not require manual frequent flipping of the step beam, and has a high degree of mechanization and automation.

[0059] like Figure 4-5 As shown, the jacking platform 1 is composed of two half-frame beams 11, specifically a first half-frame beam and a second half-frame beam. The upper connecting plates of the first and second half-frame beams are provided with through-holes, and the opposite sides are fixedly connected by bolt assemblies. The bottom surface of the half-frame beam 11 is provided with a half-frame beam cylinder lug plate 111, which has a through-hole and fastens the half-frame beam 11 to the piston rod pin of the vertical jacking cylinder 41 of the jacking hydraulic device 4. The top of the half-frame beam 11 is provided with a half-frame beam upper lug plate 112, which has a through-hole and fastens the half-frame beam 11 to the cylinder pin of the horizontal propulsion cylinder 51 of the stepping beam hydraulic propulsion device 5. The top of the half-frame beam 11 is also provided with two guide seat assemblies 113. The guide seat assemblies 113 include two guide seats at a certain distance, which allow the stepping beam 52 of the stepping beam hydraulic propulsion device 5 to move relative to each other. The semi-frame beam 11 is provided with rollers 114 , which are symmetrically arranged with two long rollers, allowing the wire rope to pass from the outside of the rollers to prevent interference with the step beam hydraulic propulsion device 5 during assembly and movement.

[0060] like Figure 6-8 As shown, the lower frame beam 2 is composed of two lower half beams 21, specifically a first lower half beam and a second lower half beam. The upper connecting plates of the first and second lower half beams are provided with through-holes, and the opposing sides are fixedly connected by bolt assemblies. A lower half beam joint 211 is provided at the bottom of the lower half beam 21, pin-fastening the lower half beam 21 to the underframe base assembly 6. An upper half beam joint 212 is provided at the top of the lower half beam 21, pin-fastening the lower half beam 21 to the upper frame beam 3. The lower half beam 21 includes a single piece 213, a crossbeam bracket 214, two diagonal braces 215, two connecting beams 216, and a support beam 217. The single piece 213 is fixed between the crossbeam bracket 214 and the two connecting beams 216. The fixed ends of the two diagonal braces 215 are symmetrically assembled within the single piece 213 and the crossbeam bracket 214. The connecting beams 216 are fixed to both sides of the single piece, and the support beam 217 is fixed between the two diagonal braces 215.

[0061] like Figure 9-11 As shown, the upper frame beam 3 includes an upper frame beam support 31, a guide wheel pair 32, and an upper frame beam lower joint 33. Eight guide wheel pairs 32 are fixed to the inner side of the upper frame beam support 31, evenly spaced above and below the upper frame beam support 31. The guide wheel pairs 32 correspond to the four sides of the standard section. The guide wheel pairs 32 include long roller guide assemblies 321 and short roller guide assemblies 322, which are arranged perpendicular to each other. The long roller guide assemblies 321 and short roller guide assemblies 322 rest on different sides of the standard section. The standard section is constructed of H-beam steel. The short roller guide assemblies 322 rest against the upper surface of the H-beam, while the long roller guide assemblies 321 rest against the two flanges of the H-beam, ensuring good guidance of the standard section during jacking and preventing interference between adjacent roller pairs when both long rollers are used. An upper frame beam lower joint 33 is fixed to the bottom of the upper frame beam support 31, pin-fastening the lower frame beam 2 to the upper frame beam 3.

[0062] like Figure 12-13 As shown, the lifting hydraulic system 4 includes four vertical lifting cylinders 41 and a hydraulic pump station for providing power to the vertical lifting cylinders 41. The cylinder bodies of the vertical lifting cylinders 41 are flange-fastened to the underframe base assembly 6, and the piston rods of the vertical lifting cylinders 41 are pin-fastened to the lifting platform 1. The four vertical lifting cylinders 41 are symmetrically distributed along the y-axis, two by two, on both sides of the lifting platform 1.

[0063] like Figure 14-16 As shown, the step beam hydraulic propulsion device 5 includes a horizontal propulsion cylinder 51 and a step beam 52. A step beam connecting ear plate 521 is provided on the cross beam of the step beam 52. The step beam connecting ear plate 521 is fastened to the piston rod pin of the horizontal propulsion cylinder 51. The cylinder body of the horizontal propulsion cylinder 51 is fastened to the ear plate 112 on the half-frame beam of the jacking platform 1 by the pin. The horizontal propulsion cylinder 51 can drive the step beam 52 to move between the two guide seats of the guide seat group 113.

[0064] like Figure 17-19 As shown, the chassis foundation assembly 6 includes a chassis foundation 61 and a steering pulley support assembly 62. The chassis foundation 61 is composed of two chassis foundation half frames 611, specifically including a first chassis foundation half frame and a second chassis foundation half frame. The inner side surfaces of the first chassis foundation half frame and the second chassis foundation half frame are fixedly connected with pins relative to each other. The upper side of the chassis foundation half frame 611 is evenly distributed with cylinder flanges 6111, standard section connecting ear plates 6112, and lower frame beam connecting ear plates 6113, which can be fastened with the vertical jacking cylinder 51 cylinder body, standard section, and lower frame beam 2 pins. The outer side surface of the chassis foundation half frame 611 is provided with a concrete foundation fixing ear plate 6114, which can be connected with the pre-embedded bolts in the preset concrete foundation. The steering pulley support assembly 62 is fixed to the chassis foundation half frame 611 by bolts so that the wire rope can run smoothly.

[0065] like Figure 20-22 As shown, the introduction track 7 includes an introduction track beam 71, an electric trolley 72, and an electric hoist 73. The introduction track beam 71 is symmetrically arranged on the inner side of the lower frame beam 2 and is fixedly connected to the single piece 213 of the lower frame beam 2 with bolts. The electric trolley 72 is operated by a worker to roll on the introduction track beam 71. The electric hoist 73 is fixedly connected to the lower middle part of the electric trolley 72 for lifting the standard section.

[0066] In this embodiment, the lower frame beam 2, upper frame beam 3, and underframe base assembly 6 define a channel for accommodating the dual-side introduction of standard sections, facilitating the entry of standard sections from various directions. This allows the frame structure to adjust the entry or exit direction of standard sections as needed. By utilizing the double-sided open lower frame beam, one side can be selected as the entry or exit for standard sections, enabling improved boom raising and lowering operations without being restricted by the actual direction.

[0067] refer to Figure 23 As shown, the lifting and heightening process is as follows:

[0068] When starting to lift, first remove the connecting pin between the standard section and the standard section base on the base frame. Figure 23 Step 1). Use the horizontal propulsion cylinder 51 to propel the step beam 52 on the hydraulic propulsion device 5 toward the standard section, so that the step beam 52 extends about 45 mm into the inner side of the standard section step. Figure 23 In step 2), after the four vertical lifting cylinders 41 are in place, they are lifted ( Figure 23 In step 3), after the step beam 52 contacts the step, continue to extend the jacking cylinder to the bottom of the tower body above the introduction track 7 ( Figure 23 Step 4); Select the side that is convenient for construction to introduce the standard section, and lift the standard section on the outside of the sleeve using the electric hoist 73 placed on the introduction track beam 71. Then, use the electric trolley 72 to introduce the standard section to the top of the standard section connecting ear plate 6112 of the chassis foundation assembly 6 ( Figure 23 Operate the electric hoist 73 to slowly lower and introduce the standard section to the standard section connecting ear plate 6112 of the chassis base assembly 6, tighten the standard section connecting pin and operate the electric trolley 72 to the outside of the sleeve ( Figure 23 After positioning, retract the vertical jacking cylinder 41 until the tower body standard section and the standard section connection hole on the underframe foundation assembly 6 are coaxial, stop the vertical jacking cylinder 41, and connect the two standard sections with a pin ( Figure 23 Step 7). Slightly lower the vertical lifting cylinder 41 ( Figure 23 (Step 8) Retract the horizontal propulsion cylinder 51) Figure 23 After step 9), the vertical lifting cylinder 41 is completely retracted ( Figure 23 Step 10 in the figure), at this point the lifting operation is completed.
