Substation, sub section post cable channel cover plate mechanical type lifting appliance
Technical field
The present invention relates to cable channel cover plate opening technology, specifically a kind of substation, sub section post cable channel cover plate mechanical type lifting appliance.
Background technology
The cable duct of substation, sub section post is sealed and installed with cover plate usually, and its effect prevents cable duct from intaking, to prevent the electrical equipment in cable duct damaged.When overhauling the electrical equipment in cable duct, need cable channel cover plate to open.At present, workmen mainly utilizes the instrument such as steel shovel, crowbar to prize cable channel cover plate, is opened by cable channel cover plate thus.Practice shows, this kind of cable channel cover plate opening technology limit due to self principle, and there are the following problems: one, and cable channel cover plate is after prizing for a long time, and its corner can be impaired, causes the leak tightness of cable channel cover plate to be deteriorated thus.Its two, when prizing cable channel cover plate, not only to waste time and energy, and careless slightly, also can cause unexpected injury to workmen.Based on this, be necessary to invent a kind of brand-new cable channel cover plate opening device, easily cause the leak tightness of cable channel cover plate to be deteriorated to solve existing cable trench cover opening technology, waste time and energy, easily workmen caused the problem of unexpected injury.
Summary of the invention
The present invention easily causes the leak tightness of cable channel cover plate to be deteriorated to solve existing cable trench cover opening technology, waste time and energy, easily cause workmen the problem of unexpected injury, provides a kind of substation, sub section post cable channel cover plate mechanical type lifting appliance.
The present invention adopts following technical scheme to realize: substation, sub section post cable channel cover plate mechanical type lifting appliance, comprise holder part and lifting part; Described holder part comprises rectangular horizontal frame, U-shaped bar, horizon bar, U-shaped handrail, U-lag, cardan wheel; The number of U-shaped bar is two; The opening of two U-shaped bars all downward; First side of two U-shaped bars is vertical edges, and second side is hypotenuse; The vertical edges lower end of two U-shaped bars respectively with the left edge of rectangular horizontal frame in the middle part of and fixing in the middle part of right edge; The hypotenuse lower end of two U-shaped bars is fixing with the left edge of rectangular horizontal frame anterior and right edge front portion respectively; The number of horizon bar is two; Two horizon bars are parallel to each other; The two ends of first horizon bar are fixing with the top margin front portion of two U-shaped bars respectively; The two ends of second horizon bar are fixed with the top margin rear portion of two U-shaped bars respectively; The opening of U-shaped handrail is towards the back lower place; The two ends of U-shaped handrail are fixed with the hypotenuse top of two U-shaped bars respectively; Downward, and the axis of U-lag and two horizon bars are parallel to each other the opening of U-lag; The outer end face of U-lag is anterior to be fixed with the middle part of first horizon bar; The outer end face rear portion of U-lag and the middle part of second horizon bar are fixed; The number of cardan wheel is four; Four cardan wheel one_to_one corresponding are installed on that the left edge of rectangular horizontal frame is anterior, the left edge rear portion of rectangular horizontal frame, rectangular horizontal frame the right edge rear portion of anterior, the rectangular horizontal frame of right edge; Described lifting part comprises Z-shaped crank, chain, suspension hook, three-jaw sucker; First horizontal sides of Z-shaped crank runs through and is articulated on two cell walls of U-lag; The number of chain is two; The number of suspension hook is three; The upper end of first chain is fastened in first horizontal sides of Z-shaped crank; First suspension hook is fixed on the lower end of first chain; The middle part of second chain is mounted on first suspension hook; Second suspension hook and the 3rd suspension hook are individually fixed in the two ends of second chain; The number of three-jaw sucker is two; The handle of two three-jaw suckers is mounted on second suspension hook and the 3rd suspension hook respectively.
Concrete use procedure is as follows: first, by two three-jaw sucker suction on cable channel cover plate.Then, along the Z-shaped crank of forward rocking-turn, Z-shaped crank reels to first chain thus, first chain is thus successively by first suspension hook, second chain-driving, second suspension hook and the 3rd suspension hook upward movement simultaneously, second suspension hook and the 3rd suspension hook drive two three-jaw suckers upward movement simultaneously thus respectively, cable channel cover plate is vertically sling by two three-jaw suckers thus, is opened by cable channel cover plate thus, thus starts to overhaul the electrical equipment in cable duct.After Awaiting Overhaul, along the Z-shaped crank of reverse rocking-turn, cable channel cover plate resets thus.In the process, substation of the present invention, sub section post cable channel cover plate mechanical type lifting appliance can be pushed to any given position and use by U-shaped handrail and cardan wheel.Based on said process, compared with existing cable trench cover opening technology, substation of the present invention, sub section post cable channel cover plate mechanical type lifting appliance is by adopting brand new, possesses following advantage: one, substation of the present invention, sub section post cable channel cover plate mechanical type lifting appliance is without the need to prizing cable channel cover plate, but drive three-jaw sucker by Z-shaped crank, and utilize three-jaw sucker to carry out vertical lifting to cable channel cover plate, effectively prevent thus and cause the corner of cable channel cover plate impaired because prizing, thus effectively ensure that the leak tightness of cable channel cover plate is good.They are two years old, substation of the present invention, sub section post cable channel cover plate mechanical type lifting appliance are without the need to prizing cable channel cover plate, but drive three-jaw sucker by Z-shaped crank, and utilize three-jaw sucker to carry out vertical lifting to cable channel cover plate, not only more time saving and energy saving thus, and effectively prevent unexpected injury is caused to workmen.In sum, substation of the present invention, sub section post cable channel cover plate mechanical type lifting appliance efficiently solve that existing cable trench cover opening technology easily causes the leak tightness of cable channel cover plate to be deteriorated, the problem of unexpected injury of wasting time and energy, easily cause workmen.
The present invention is rational in infrastructure, it is ingenious to design, and efficiently solves that existing cable trench cover opening technology easily causes the leak tightness of cable channel cover plate to be deteriorated, the problem of unexpected injury of wasting time and energy, easily cause workmen, is applicable to the unlatching of cable channel cover plate.
