DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following preferred embodiments are used to further describe the utility model in detail.

[0025] EMBODIMENT

[0026] Please refer to the accompanying drawings Figures 1-6 As shown in the drawings, the multi-stage guide column 100 provided by the embodiment comprises a multi-stage guide column body, a base end connecting plate 107 and a stage end connecting plate 1015. The multi-stage guide column body comprises a base end guide column 101, an intermediate guide column 102 and a stage end guide column 103 arranged from outside to inside. The base end connecting plate 107 is fixedly connected with the lower end of the base end guide column 101, and the stage end connecting plate 1015 is fixedly connected with the upper end of the stage end guide column 103. The base end guide column 101 and the intermediate guide column 102 are in rolling contact through a plurality of steel ball rollers 108, and the intermediate guide column 102 and the stage end guide column 103 are also in rolling contact through a plurality of steel ball rollers 108. The steel ball rollers 108 between the base end guide column 101 and the intermediate guide column 102 are installed through the steel ball roller 108 installation holes formed on the intermediate guide column 102, and the steel ball rollers 108 between the intermediate guide column 102 and the stage end guide column 103 are installed through the steel ball roller 108 installation holes formed on the stage end guide column 103.

[0027] In the embodiment, the base end connecting plate 107 and the stage end connecting plate 1015 are both made of steel plates. The base end connecting plate 107 is fixedly connected with the embedded plate on the ground of the foundation pit through anchor bolts, and the stage end connecting plate 1015 is bolted with the stage lifting platform steel structure 200.

[0028] Specifically, the stage end guide column 103 has the same structure as the intermediate guide column 102 and the base end guide column 101. The stage end guide column 103 includes two guide column A plates 1010 and two guide column B plates 1011, which form a rectangular column. The two guide column A plates 1010 and the two guide column B plates 1011 are arranged opposite each other. Column plate connection holes 1014 are provided on both guide column A plates 1010 and guide column B plates 1011. The guide column A plates 1010 and guide column B plates 1011 are connected by column mounting bolts 109 that pass through the column plate connection holes 1014. Connecting the guide column A plates 1010 and guide column B plates 1011 with column mounting bolts 109 ensures installation accuracy and good manufacturability.

[0029] Specifically, the stage-end guide column 103 is provided with a plurality of steel ball rollers 108 arranged in multiple vertical rows. The inner surfaces of the guide column A plate 1010 and guide column B plate 1011 of the intermediate guide column 102 are each provided with multiple rows of straight guide grooves 1012 that match the steel ball rollers 108 on the stage-end guide column 103. The steel ball rollers 108 on the intermediate guide column 102 are arranged in multiple vertical rows. The inner surfaces of the guide column A plate 1010 and guide column B plate 1011 of the base-end guide column 101 are each provided with multiple rows of straight guide grooves 1012 that match the steel ball rollers 108 on the intermediate guide column 102. The steel ball rollers 108 complete multi-stage guiding motion by moving along the straight guide grooves 1012, and the rolling of the steel balls makes the operation of the multi-stage guide columns smoother and prevents jamming.

[0030] Specifically, the upper and lower ends of the outer surfaces of the stage end guide column 103 and the middle guide column 102, and the upper ends of the inner surfaces of the middle guide column 102 and the base end guide column 101 are all fitted with travel limit blocks 105 via limit mounting bolt groups 104. The travel limit blocks 105 limit the vertical movement of the stage end guide column 103 and the middle guide column 102.

[0031] Specifically, nylon limiters 106 are installed at the bottom of both the intermediate guide post 102 and the base end guide post 101. The nylon limiters 106 ensure that the stage end guide post 103 and the intermediate guide post 102 will not slip to the bottom, ensuring stability and strong resistance to impact and vibration.

[0032] In this embodiment, the hole spacing between the mounting hole of the steel ball roller 108 and the connecting hole of the column plate 1014 is 100mm.

[0033] Application Example 1

[0034] like Figure 7As shown, the multi-stage guide column 100 for stage lifting platforms in Example 1 is used in conjunction with the stage lifting platform lifting column 300 to linearly guide and lift the steel structure 200 of the stage lifting platform. In this example, the stage lifting platform lifting column 300 is a screw-driven lifting column.

[0035] Application Example 2
