Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, a kind of multi-layer cable gantry more changing device of the utility model, including
Bracket 10 erects setting；
Chain block 20, is provided with two hook up and down, and upper hook 21 and lower draw-bar 22 pass through hook with chain block 20
Chain 23 is connected；Wherein 21 hook of upper hook is set to 10 top of bracket；
Cable hanging piece 30 comprising phase the same end of multiple hanging axises 31 set gradually from top to bottom, multiple hanging axises 31 is logical
It crosses connection chain 32 to be connected, axle sleeve 33 is arranged on hanging axis 31, multiple axle sleeves 33 are for tangling multi-cable, 31 liang of the hanging axis at top
End is connected with one point of chain 34 respectively, and two points of chains 34 are connected by a main chain 35 with lower draw-bar 22；
When work, chain block 20 is pulled manually, and lower draw-bar 22 can be driven vertically movable and keeps cable hanging piece 30 synchronous
It is mobile, to realize the quick-replaceable of cable testing bridge.
This replacement apparatus structure is simple, easy to make, at low cost, can quickly replace to cable testing bridge.
On the basis of the said structure, the utility model has been made it to be further improved and refined.
As shown in Figure 1,31 diameter of axle of hanging axis is less than the aperture of connection chain 32, hanging axis 31 passes through connection chain 32 and passes through spiral shell
