The specific embodiment
Referring to Tu1～Tu3， substation packaged type cable cover crane carriage, comprise main frame 1, upper frame 2, hand winch 3, stay cord 4 and link up with 5; Described main frame 1 comprises four root posts, four entablatrances and four cross sills; Described four root posts comprise the first column 101, the second column 102, the 3rd column 103 and the 4th column 104; Described four entablatrances comprise the first entablatrance 105, the second entablatrance 106, the 3rd entablatrance 107 and the 4th entablatrance 108; Described four cross sills comprise the first cross sill 109, the second cross sill 110, the 3rd cross sill 111 and the 4th cross sill 112;
Each root post bottom of described four root posts is provided with a cardan wheel 6 that can drive dolly to move and can auto-steering;
Described upper frame 2 comprises two stands and a push rod 203; Described two stands comprise left standing frame 201 and right standing frame 202; Described left standing frame 201 is fixed on described the 4th entablatrance 108, described right standing frame 202 is fixed on described the second entablatrance 106, the left end of described push rod 203 is fixed on the top of described left standing frame 201, and the right-hand member of described push rod 203 is fixed on the top of described right standing frame 202; Described hand winch 3 is fixed on the middle part of described push rod 203;
The left part of described push rod 203 and right part are respectively provided with a fixed pulley 7; On described hand winch 3, be wound with described stay cord 4, the two ends of described stay cord 4 are walked around respectively the end at stay cord 4 after the fixed pulley 7 at described push rod 203 two ends and are fixed with a described drag hook 5;
On described drag hook 5, hang with one for tangling the grapple 8 of cable cover.
In the time of need to lifting by crane cable cover, pushing away dolly and moving to cable cover place.The hook of grapple lower end is inserted in the aperture on cable cover, and then rotation manual capstan winch, pulls stay cord to drive hook and grapple to rise, thereby drives cable cover to rise.Then remove dolly, staff patrols and examines.Patrol and examine after end, dolly is retracted and loosened hand winch, cable cover is put down, the work of patrolling and examining that completes is built in original place.Then promoting dolly carries out next place and patrols and examines.
This by the mode of dolly and hand winch lifting cable cover, light and fast, moves and lifts by crane all very convenient.Even if female employee and older, can sling cable cover very rapidly.Experiment showed, and adopt after dolly of the present invention, lifting move and averaging time of time of recovering cover plate less than 5 minutes, greatly improved the efficiency of patrolling and examining of cable duct.And, by hook and grapple, firmly grasp cover plate, that cover plate is firmly grasped is very firm, has reduced the incidence of the accidents such as personal injury, damage cover plate, cover plate come off, and has improved the safe reliability of the work of patrolling and examining.
The space framework of described four root posts, four entablatrances and a four prism type of four cross sill formations; Four entablatrance the first connections successively, form a rectangular frame.
Described stand comprises three rod members; Three rod members of left standing frame 201 and described the 4th entablatrance 108 form a trapezoidal framework, and three rod members of described right standing frame 202 and described the second entablatrance 106 form a trapezoidal framework.Left and right stand adopts trapezium structure, and fastness is good.
Described grapple 8 comprises two identical hooks; Described hook comprises suspension ring 801 and crotch 802; Described suspension ring 801 are fixed on one end of described crotch 802.
As Fig. 2, during use, the direction of the crotch of two hooks is contrary, forms a two-way grapple, the two-way grapple of the eave tile right formation of one the first from left of crotch.Snap in " handle hole " of cable cover diameter 2cm from both direction within, clamp effective, cable cover difficult drop-off.If Fig. 3 is the constructional drawing of one of them hook, two back-to-back uses of hook, can clamp the both sides of the handle hole of cable cover, thereby avoid cover plate to drop.
The process of lifting cable cover is as follows: by the back-to-back cover plate aperture of putting into of two hooks of two-way grapple, suspension ring are inserted in grapple handle; 2, crane carriage is pushed into and needs mobile cover plate top, the four wheels of dolly is locked fixing, the dropping-proof hook of hand winch is buckled in the suspension ring of grapple top; 3, the hand hand winch of operating personal, to proper height, opens the four-wheel blocking device of dolly by cover plate lifting; 4, travelling car, is transferred to designated area by cover plate.
Compare with the operating mode of manual unlocking cable cover, substation of the present invention packaged type cable cover crane carriage has following technological merit.
The first, a dead lift cover plate, the person is easily hurt; Substation of the present invention packaged type cable cover crane carriage is used grapple, has avoided personal direct contact cover plate, has also just eliminated personal safety hidden danger;
The second, a dead lift mode, with crow bar lifting cover plate, easily causes cover plate cracking and damages side edge thereof situation; Substation of the present invention packaged type cable cover crane carriage, is used two-way grapple, really prevents tool damage cover plate;
The 3rd, a dead lift mode, manual operation, cover plate easily comes off, and smashes cable.Substation of the present invention packaged type cable cover crane carriage, is used crane carriage no matter lifting, movement or all can fixedly secure cover plate while recovering cover plate, has stopped cover plate and has come off.
