Detailed description of the invention

Below in conjunction with drawings and Examples, the present invention is described in further detail.

The invention provides a kind of jack up hanging cable stage apparatus, for hanging suspension cable 20 on Sarasota 10, including: extremely Few two truss 30, adjacent two truss 30 lay respectively at the both sides of suspension cable 20, and each truss 30 all includes at least one Fagging 40, gripper shoe 40 is horizontally located on truss 30;At least one pedal 50, pedal 50 Slide Group is located on truss 30, pedal 50 for overlapping adjacent two truss 30 in the horizontal direction;At least two elevating mechanisms 60, elevating mechanism 60 and Sarasota 10 Affixed, each elevating mechanism 60 connects a truss 30 respectively, and elevating mechanism 60 drives the truss 30 being attached thereto to lift.Truss 30 Between separate, elevating mechanism 60 drives the truss 30 that is attached thereto individually to climb, when hanging multiple row suspension cable 20, it is not necessary to Wait that the operator in all truss 30 just climbs after having operated whole stage apparatus, can shorten the waiting time, improve operation effect Rate.

Shown in Figure 1, in the present embodiment, there are two row suspension cables 20, jack up hanging cable stage apparatus bag in the side of Sarasota 10 Including three truss 30, adjacent truss 30 lays respectively at the left and right sides of suspension cable 20.According to the position distribution of truss 30, by truss 30 are divided into middle truss and fringe truss, and being positioned at the truss 30 in the middle of two row suspension cables 20 is middle truss, is positioned at two row suspension cables 20 other Two truss 30 on limit are fringe truss.

Two fringe trusses are provided with pedal 50, and middle truss can arrange pedal 50.Pedal 50 Slide Group is located at limit In the gripper shoe 40 of truss, for overlapping adjacent two truss 30 in the horizontal direction.Truss 30 is adjacent with another truss 30 Side is that π type connects architecture, is available for pedal 50 and stretches out, it is simple to operator passes through, and can reinforce this stage apparatus.Truss 30 Other side is that N-type connects architecture, effectively plays the effect of safeguard protection.

Before operator carries out hanging cable operation, pedal 50 is stretched out, make between fringe truss and middle truss, to form People's Bank of China horizontal Road, operator moves to the lower section of suspension cable 20 along pedal 50, carries out hanging cable operation.After operator hanging cable completes, operator Move back to, in truss 30, be then retracted in fringe truss by pedal 50.

All having four gripper shoes 40 on each truss 30, gripper shoe 40 is horizontally located on truss 30, and is equidistantly distributed. Gripper shoe 40 is available for supporting operator, and in same truss 30, the spacing of adjacent shore plates 40 is more than the height of operator.Truss 30 Lower end side is provided with an open pull door.

Being additionally provided with a vertical cat ladder 70 on each truss 30, this vertical cat ladder 70 is through all gripper shoes on this truss 30 40 so that an operator can hang multiple skew cables 20 in multiple regions of truss 30, save manpower, greatly increase The efficiency of hanging cable construction, shortens construction period.

Shown in Figure 2, truss 30 is also equipped with stop 80, stop 80 is positioned at pedal 50 two in the width direction Side, this stop 80 blocks pedal 50, and limiting pedal 50 can only slide along its length, and this stop 80 and pedal 50 it Between suitably leave gap, reduce the sliding friction between pedal 50 and stop 80, it is simple to pedal 50 stretches.

Shown in Figure 3, in the present embodiment, Sarasota 10 both sides are mounted on jack up hanging cable stage apparatus, can enter simultaneously Row hanging cable operates, and efficiency of construction is high.This jack up hanging cable stage apparatus also includes three elevating mechanisms affixed with Sarasota 10 60.This elevating mechanism 60 includes motor 61, jack 62, guide rail 63, and wherein, motor 61 connects and drives jack 62 to lift, Jack 62 truss frame for connecting 30, and then drive the truss 30 being attached thereto to lift, truss 30 lifts along guide rail 63 direction.

When the position needing hanging cable is down to by truss 30 liters, motor 61 stops operating, and between truss 30 and guide rail 63 Several latches are installed, fix hanging cable stage apparatus, carry out hanging cable operation.When needs lifting hanging cable stage apparatus, extract Latch, motor 61 drives hanging cable stage apparatus to lift.

The jack up hanging cable stage apparatus of the present invention is affixed with Sarasota 10 so that hanging cable platform is firm, even if there being wind In the case of can also hang suspension cable 20, adaptive capacity to environment is strong, shortens construction period.

The present invention is not limited to above-mentioned embodiment, for those skilled in the art, without departing from On the premise of the principle of the invention, it is also possible to make some improvements and modifications, these improvements and modifications are also considered as the protection of the present invention Within the scope of.The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
