The electromagnetic field that can around produce alternation is held, because electric current is larger, the alternating electric field of two cables and air switch is also larger, alternating electromagnetism
Interact produce mechanical oscillation, temperature exceed normal range (NR) when, some cables due to basal area select it is small, more than specified load
Flow, cable laying is not compact or there is the phenomenons such as vortex, and generation cable outer insulation breakage punctures and cable falls frame accident.
Two is that, due to power load change, cable causes to stretch compression and fatigue cracking in vibration crooked position.Three are produced due to vibration
The dynamic external insulation layer of cable mite rubs with cable bearer and damages.Above-mentioned reason can only carry out unplanned property power failure inspection to tunnel cable
Repair, power supply reliability can be substantially reduced, reduce power supply quality, influence Business Economic Benefit.
The maintenance of cable needs to raise cable from crane span structure, Bian Yu Jian Xiu operations, especially crane span structure in cable repair and maintenance
The lifting maintenance of Road cable and upper road cable is extremely difficult, and lifting utensil cannot be placed without the strong point is elevated because of cable bottom,
In the prior art, cable lifting needs to set up shears, and using suspender lifting cable, maintenance people squats and lies in cable downside work
Make, it is possible to which pernicious injury accident of the tripod fulcrum inclination across Games occurs, while also for cable later maintenance brings many tired
It is difficult.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of lifting apparatus for overhauling tunnel cable, can be in tunnel
Inside above the ground just quick lifting cable, quick for installation with simple structure, the characteristics of improve maintenance efficiency of construction.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of lift for overhauling tunnel cable
Rise device, including channel-section steel bearing, the groove box and hanging scroll of fixed jack；The channel-section steel bearing right side bottom surface is provided with vertical slots
Hole, is respectively equipped with symmetrical transposition hole on the front and rear two side of channel-section steel bearing, the hanging scroll is inserted in symmetrical transposition hole,
The front and rear vertical plates on both sides of the groove box left part is flexibly connected with hanging scroll both ends, and groove box bottom left end withstands on the right side of channel-section steel bearing
On the bottom surface of side.
It is to further improvement of the utility model：
The quantity of the channel-section steel bearing is solid with connecting plate and bolt between channel-section steel bearing in two or more and in docking up and down
Fixed, the bottom positioned at the channel-section steel bearing of bottom is provided with base.
Wheel and wheel pull bar are set up, the bottom of the channel-section steel bearing of the bottom is additionally provided with wheel and wheel pull bar.
Horizontal jack is set up, the Horizontal jack is arranged in groove box by fastening bolt, the pressure of Horizontal jack
Vertical slotted eye of the power bar from channel-section steel bearing stretches out.
Cable supporting plate is set up, the cable supporting plate top is provided with multiple arc grooves for accommodating cable, the cable supporting plate
Bottom is provided with the sleeve being flexibly connected with the top of Horizontal jack.
Roll adjustment plate is set up, the roll adjustment plate is symmetrically connected in the front and rear vertical plates on both sides of groove box bottom left end by bolt,
By the transverse shift regulating tank box and the angle of channel-section steel bearing of roll adjustment plate.
It is using the beneficial effect produced by above-mentioned technical proposal：Channel-section steel bearing is arranged on tunnel ground by the utility model
On face, the groove box being flexibly connected with channel-section steel bearing is installed below in cable, Horizontal jack is fixed in groove box, hanging scroll is by changing
Position hole changes position makes the Angulation changes of groove box and channel-section steel frame plate, mobile roll adjustment plate to carry out angle adjustment, make horizontal very heavy
Top can from different angles above lifting cable.Channel-section steel bearing can make Horizontal jack lifting different layers in docking up and down
Secondary cable.The utility model simple structure, assembling is quick, and the convenient movement in tunnel is overhauled to cable, can be reduced
Labour intensity, it is ensured that construction safety, raises labour efficiency.
