Abstract
The utility model provides a lifting appliance for the transformer substrate isolating switch which connects with a bracket between two installing support columns of the insolating switch, connects with a lifting standing derrick on the bracket, fixes a crown block on the lifting standing derrick top side, a hoisting cable drew from a windlass connects with a hook round the crown block. The lifting appliance fixes two installing columns of the lifting standing derrick near the isolating switch, connects with the lift device through the crown block, hositing cable and windlass on the lifting standing derrick top for lifting the device which can reach aims of save-labour, save-time and ensuring safety.
Description
Technical field
The utility model relates to the substation isolating-switch boom hoisting.
Background technology
Because isolating switch in the 220kV transformer station, press become, rheology layout in transformer station is intensive, powers failure is range limited, the operation place is narrow and small, mechanical crane and bigger lifting gear can't enter operation field.Past all is to install for loose mail equipmentization is whole during erection unit.Labour intensity, danger coefficient are all very big.
Summary of the invention
The purpose of this utility model provides a kind of boom hoisting that is used for substation isolating-switch.
This substation isolating-switch boom hoisting is to connect support between two mounting columns of isolating switch, connects the lifting gin pole on support, and at the fixing fixed pulley of lifting gin pole tip-end-side, the steel wire rope of drawing from hoist engine is walked around the end connecting shackle of fixed pulley.
As improvement, described support is made up of two channel-section steels.The length of best described channel-section steel is greater than 2.65m, with greater than distance (being generally 2.65m) between two mounting columns of isolating switch.
As improvement, described lifting gin pole becomes to removably connect with two channel-section steels.
This device will lift by crane gin pole and fix by two mounting columns of isolating switch, couple together by fixed pulley, steel wire and the hoist engine at gin pole top and the equipment that hung and carry out the equipment lifting, reach the time saving and energy saving purpose that ensures safety.
Description of drawings
Fig. 1 is the front view of present embodiment.
Embodiment
Boom hoisting shown in Figure 1, it by a small winch 1, steel wire 2, lifting gin pole 3 and fixed pulley 4, directive wheel 14, suspension hook 5 and fixedly channel-section steel 6 etc. form.Fixedly channel-section steel has adopted two #6 channel-section steels that length is 3.25m, and is that the semicircle shroud ring of 0.30m is fixed on the mounting column 7 of isolating switch with 4 diameters, is mainly used to the fixed hoisting gin pole.It is 0.07m, thickness of pipe wall 0.006m length that the lifting gin pole adopts diameter, be the round steel pipe of 6.00m.In three positions in centre and both sides of channel-section steel perforating boring, the aperture is 0.018m, as three positions of fixed hoisting gin pole.
When the lifting gin pole is fixed on channel-section steel middle, lift by crane disconnecting link pedestal 8 usefulness; When being fixed on a side of channel-section steel, lifting insulator and conducting rod are used.
Weight according to the lifting article, having adopted load is 1 ton suspension hook and steel wire, adapted a small winch and some pulleys, at the fixing fixed pulley of lifting gin pole tip-end-side, the steel wire rope of drawing from hoist engine is walked around the end connecting shackle of fixed pulley behind directive wheel.Like this, just formed the easy boom hoisting of a cover.
When beginning the lifting installation, earlier the shroud ring of two #6 channel-section steels with Φ 300 is fixed on the dress pillar.Then, will lift by crane gin pole and be fixed on channel-section steel central authorities lifting disconnecting link pedestal.Behind the pedestal rigging out, the lifting gin pole is moved on to the fixing supporting insulator and the conducting rod of both sides installed respectively in channel-section steel both sides respectively.When lifting, divide four direction colligation location at lifting gin pole top with rope, the stressed of gin pole is uniformly distributed in all around and fixing channel-section steel, in order to avoid gin pole is because of unbalance stress.
This boom hoisting is simple in structure, and is in light weight, is easy to assembling, realized carrying out under the situation that no large-scale lifting tool is assisted the lifting and the installation of equipment, and the work of saving time, improved is renderd a service, and the more important thing is and has improved safety factor of workers.
