Abstract
The utility model discloses a hoisting tool for replacing an isolation switch. The hoisting tool comprises a base, a vertical rod, a lifting arm, a lifting rope, a lifting hook, replaceable hold hoops and a lifting operation device. The vertical rod is connected with the base through rolling bearings; the vertical rod is connected with the lifting arm; the lifting hook is connected with the lifting operation device through the lifting rope; the rod body of the vertical rod is provided with the replaceable hold hoops; and the lifting operation device is fixedly connected to the rod body of the vertical rod. The hoisting tool for replacing the isolation switch is reliable and safe; power failure time for operating a bus can be effectively reduced; and the hoisting tool can be used flexibly and conveniently in relatively small space during working.
Description
Technical field
The utility model belongs to power supply unit to be installed and maintenance technique field, relates in particular to a kind of lifting device of changing isolation switch.
Background technology
In power supply unit is installed and is keeped in repair, there are two very large drawbacks in the lifting work that traditional work is used crane to carry out isolation switch: in old disconnecting link dismounting and new disconnecting link hoisting process, because safe distance between crane crane arm and bus is inadequate, so must, by Generatrix cease, cause quite long interruption duration; Limited to by transformer station locus, as too compact in equipment in portal frame, the interior porte-cochere of standing affects apart from factors such as isolation switch are too far away, equipment interval internal wiring is intensive, causes crane operation difficulty, even cannot operation.Continuous expansion along with electrical network scale, transformer station's newly added equipment quantity significantly improves, if under the condition of Generatrix cease, by crane, carry out more changing jobs of isolation switch, the power supply reliability of electrical network will have been had a strong impact on, so long non-fault interruption duration has greatly reduced the productivity effect of company simultaneously, has caused company and society economic loss greatly.
Utility model content
The utility model, in order to solve weak point of the prior art, provides a kind of lifting device that can effectively reduce replacing isolation switch flexible when moving the interruption duration of bus and working.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of lifting device of changing isolation switch, comprise base, vertical rod, arm, lifting rope, suspension hook, replaceable anchor ear and lifting operating means, vertical rod is connected by rolling bearing with base, vertical rod is connected with arm, suspension hook is connected with lifting operating means by lifting rope, is provided with replaceable anchor ear on the vertical rod body of rod, and lifting operating means is fixedly connected on the vertical rod body of rod.
Described vertical rod is three stage structure.
Described replaceable anchor ear is provided with 4.
Described lifting operating means is hand-rail type operating mechanism, and is provided with auxiliary-handle, brake and anti-loosing device.
On described suspension hook, be provided with locking device.
Described lifting operating means is fixedly connected with by latch closure device and pin with the vertical rod body of rod.
Adopt technique scheme, vertical rod adopts three stage structure, carries out field joint during work, can not only reach the effect of integrative-structure, and the transportation of being more convenient for; Suitable rolling bearing is installed in the junction of base and main body vertical rod, has improved the rotation flexibility of hanging device; Lifting operating means is set to hand-rail type operating mechanism, and is provided with auxiliary-handle, brake and anti-loosing device, has improved reliability, the fail safe of hanging device; Adopt replaceable anchor ear hanging device main body firmly can be fixed on isolation switch base frame; On suspension hook, install locking device additional, guaranteed the firm and slip-off preventing characteristic of suspension hook.The utility model has reduced the interruption duration of changing isolation switch: greatly ensured power supply reliability and fail safe, increased the benefit of company simultaneously; Avoided the grid switching operation that has a power failure and to carry out because of bus, the workflow of significantly having simplified operator, has reduced the loss of grid equipment; Do not use crane and bucket arm vehicle, reduced job that requires special skills equipment and driver's task, reduced the oil consumption toll of vehicle and extra operating cost, reduced environmental pollution simultaneously yet; Reduced and changed the operation number of keeping apart disconnecting link, shortened the operating time, greatly improved the operating efficiency of service work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of vertical rod;
Fig. 3 is the structural representation of replaceable anchor ear.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, when the utility model is used, select suitable upper part 8, middle-end part 9 and end portion 10 docking composition vertical rod 2 according to this, in the junction of base 1 and vertical rod 2, suitable rolling bearing is installed, adjust lifting rope 5 and suspension hook 6 positions; To the vertical rod 2 connecting be erected, be fitted on the base frame of isolation switch, then four anchor ears 4 are adjusted to respectively to suitable height, buckle anchor ear vertical rod 2 is steadily fixing, fixed screw; Forward arm 7 to the position perpendicular with base frame, and joystick and brake handle are arranged on the operating mechanism 3 of hanging device, by lifting rope 5, disconnecting link is hung on suspension hook 6; Hand operation is by disconnecting link integral lifting, after height at isolation switch base higher than base frame, an other people presses brake and fixes position, by the staff's rotating operation dish 3 that just now carried out hand operation, drive the rotation of vertical rod 2, thereby make isolating switch rotate to the correct position on base frame; Select suitable screw that isolation switch is fixed on base frame, unclamp suspension hook and pull down lifting rope, the installation process of isolation switch completes.
According to the relevant regulations of safety regulations, when the utility model is worked at 100kV power supply unit, the whole height of hanging device is preferably 5 meters, but it can be any one in 4.6～5.7 meters of numerical value; When 220kV power supply unit is worked, the whole height of hanging device is preferably 6 meters, but it can be any one in 5.3～6.1 meters of numerical value.According to the structure of working site isolation switch framework and concrete pedestal platform, the size of determining hanging device base 1 is 40*40 centimetre.
During use, should note: if 1. isolation switch is stretched structure, steadily firm when being bundled on isolation switch moving contact member and tightening lifting rope and guarantee lifting with lifting rope, lift by crane rotation porcelain vase and fixedly porcelain vase and switch base are installed after certain height on the spot; If goat's horn type isolation switch, first disconnecting link is assembled completely, then lifting rope is wrapped in to the position on the lower of two porcelain vases, lift by crane after tightening lifting rope.2. in the whole process of lifting isolation switch, should stand on staircase and hold up isolation switch by two staff, prevent that porcelain vase and base frame from friction or collision occurring.3. in the process of lifting isolation switch, also can be on the correct position of isolation switch fixing wind rope, by stand in ground staff be responsible for dilatory, thereby play the effect of adjusting isolation switch position that coordinates.
