Pipe hidden danger can be caused necessarily to break during row to steam generator heat-transfer pipe (such as to heat-transfer pipe shock and vibration, extruding, abrasion, corrosion
Deng), influence the security reliability of heat-transfer pipe.And narrow space in steam generator secondary side cylinder, it can only be installed by hand hole
The wall dolly of climbing for carrying detection means is checked cylinder inboard wall, tube sheet and heat-transfer pipe, realizes that steam generator secondary side is complete
Face is checked.
Climb wall dolly to adsorb using permanent magnet and motor-drive technique, can be adsorbed on steam generator inner tube wall, this is climbed
Wall dolly includes：Wobble component, small vehicle main body and the part of cable concentrator three, realization keep straight on, turned to, swinging, pushing away and the function such as pull out, and can transport
Move to specified location, complete corresponding check.
Climb wall dolly and use articulated structure, main purpose is that the convenient hand hole by steam generator is installed to steam hair
On raw device inner tube wall.The small vehicle main body and wobble component for climbing wall dolly are all provided with centrally-mounted driving, and conventional cable is general all exposed
Outside equipment, easily by environmental influence in running, it is also easy to wind, or rub with other structures
Situations such as, cable abrasion, rupture, or even fracture are caused, so that the problems such as causing electric leakage, signal interruption, influence equipment is normally transported
OK.
The content of the invention
The purpose of this utility model be to provide it is a kind of be used to climb the intra-articular Wiring structure of wall dolly, can adapt to climb wall small
Car each joint opposing oscillatory structure prevents cable from coiling and abrasion condition occur, while ensureing to climb the phase in wall car interior space
To sealing, prevent the steam in environment from electric elements are caused with damage.
The technical solution of the utility model is as follows：One kind is used to climb the intra-articular Wiring structure of wall dolly, and the structure includes closing
A, support shaft and joint B are saved, wherein, joint B is provided with protruding part, and it matches with the groove structure in the A of joint, support
Axle inserts joint A and the through hole of joint B coupling parts, by joint A and joint B connections；The support shaft one end open, and side
Wall perforate inside the B of joint with being connected, and the cable in the A of joint is entered in the B of joint by support shaft one end open and areole
Portion.
Flat hole is provided with described joint A, it coordinates with the flat shaft part in support shaft, prevents support shaft from occurring to turn
It is dynamic.
Described joint B can around support shaft in the range of certain angle reciprocally swinging.
Described support shaft one end is stepped cylindrical structure, and the other end is the opening cylinder structure that there is partially flat shaft part；Branch
The stepped cylindrical structure of support axle is fixed on the A of joint by being cased with the soket head cap screw of spring pad.
Described support shaft and joint A contact surface are provided with O-ring seal；The contact with joint B of described support shaft
Face is provided with O-ring seal.
Remarkable result of the present utility model is：It is described in the utility model a kind of for climbing wall dolly joint interior cabling knot
Structure, two joint support, positioning, the requirement such as cable wiring and sealing, it is to avoid outside cabling is affected by environment, proposes can be met simultaneously
The adaptive capacity to environment of high equipment, improves the reliability of equipment.
