Description
Technical field
The utility model relates to power equipment transport fields, and in particular to a kind of suspender.
Background technique
Power distribution cabinet (case) is to assemble switchgear, measuring instrumentss, protection electric appliance and ancillary equipment by electrical wiring requirement
In closing or semiclosed metal safe or in screen width, the low-voltage distribution equipment of composition.It can be by manually or automatically when normal operation
Switch connection or disjunction circuit.By protection electric appliance cutting circuit or alarm when failure or irregular operating.
Since the size and weight of power distribution cabinet are larger, power distribution cabinet transported to scene when being installed, need to use dedicated
Suspender is lifted, and the structure of special hanger generally includes a horizontal girder, is fixed with lifting rope and tie string on girder,
Lift using special hanger that general there are two types of modes: the first is that tie string is passed through power distribution cabinet bottom, then uses crane
Lifting rope on girder is lifted, but is easy to cause power distribution cabinet crooked in hoisting process using such mode, skew
The main reason for be the midpoint tied up always at both ends of center of gravity being unable to ensure after power distribution cabinet lifting, as long as slightly error will
Occur skew, the weight of power distribution cabinet is bigger in addition is calculated with ton, therefore, power distribution cabinet in hoisting process once
Occur skew would generally put down carry out it is secondary tie up adjustment, lift by crane again, be otherwise easy to cause in power distribution cabinet hoisting process and occur
The safety problems such as landing；Second is four lifting lugs of installation on the top plate of power distribution cabinet, tie string is passed through lifting lug, then use crane
Lifting rope on girder is lifted, this mode can effectively avoid power distribution cabinet from occurring skew in hoisting process, but due to
Power distribution cabinet weight is larger, and lifting lug, which is easily deformed, to be even broken, and serious safety accident occurs, and since lifting lug is mounted on distribution
In cabinet top plate, it is easy to cause top plate to deform during lifting.
Utility model content
The purpose of this utility model is to provide a kind of suspenders, are hung when solving lifting power distribution cabinet at present using lifting lug
The problem of power distribution cabinet roof deformation is easy to happen when the mode of dress.
In order to achieve the above objectives, the utility model adopts the following technical solution:
A kind of suspender, including girder, girder are equipped with lifting rope, and girder both ends are equipped with tie string and two hoisting ropes,
The length of tie string is greater than the length of hoisting rope, is connected with strainer between the tie string at girder both ends.
The principle and beneficial effect of this programme are:
Hoisting rope is first passed through the lifting lug in distribution cabinet top plate when lifting to be fixed, then crane is by the lifting on girder
Rope is lifted, and girder is lifted slightly upwards, so that the upward out ground certain distance of power distribution cabinet, worker will tie up again at this time
Rope across power distribution cabinet bottom, but between tie string and power distribution cabinet be at this time it is loose, tie string is simultaneously not affected by from power distribution cabinet
Pressure, i.e. tie string do not play a supporting role to power distribution cabinet, and power distribution cabinet is still only played a supportive role by hoisting rope, girder both ends
Tie string between the strainer that connects for driving two tie strings tensionings so that tie string and hoisting rope jointly by
Power.
Following technical effect can be reached using this programme:
Power distribution cabinet is supported jointly by tie string and hoisting rope, the stress of hoisting rope is on the one hand can be reduced, that is, subtracts
Small hoisting rope reduces the possibility of lifting lug damage to the pulling force of lifting lug, while also reducing the possibility of power distribution cabinet roof deformation, another party
Face since hoisting rope by lifting lug lifts power distribution cabinet, position of the lifting lug in distribution cabinet top plate be it is fixed, be avoided that
Skew occurs in hoisting process, lifts by crane more stable.
Further, strainer includes the worm gear being meshed and worm screw, and worm gear and worm screw are rotatably connected on girder, main
The tie string one end at beam both ends is each attached on girder, the other end winds and is fixed on worm gear, and girder both ends are tied up
Winding direction of restricting is opposite.Worm screw rotation drives worm gear rotation, due to two tie string winding directions on worm gear on the contrary, worm gear rotates
When can drive the tensioning of two tie strings, and since worm and gear has self-locking performance, i.e., worm gear rotation can only be driven by worm screw, and
Worm screw rotation cannot be driven by worm gear, i.e., when tie string is by gravity from power distribution cabinet, tie string not will drive worm gear rotation,
I.e. tie string will not be loosened from worm gear, ensure that tie string in hoisting process can remain the lifting power to power distribution cabinet.
Further, strainer further includes motor, and motor is fixed on girder, and motor output shaft is connected with worm screw.It is logical
It crosses motor work and drives worm screw rotation, avoid and manually screw the time-consuming and laborious problem of worm screw.
Further, tie string is located on the outside of hoisting rope.Tie string is wound on power distribution cabinet using this structure worker that is more convenient for.
Further, girder and tie string junction are equipped with twine guide plate, and rope guiding hole, the axis of rope guiding hole are offered on twine guide plate
Line is vertical with the axis of girder.Rope guiding hole can play the role of guiding to tie string, so that tie string movement is more smooth.
Further, wearing layer is equipped on the inside of rope guiding hole.Wearing layer can reduce tie string to the abrasion on the inside of rope guiding hole.
Further, the seamed edge of rope guiding hole uses arc transition.Abrasion of the rope guiding hole to tie string can be reduced using this structure.
Further, rope groove there are two setting on the side wall of worm gear, two rope grooves are vertical with the axis of worm gear, girder both ends
Tie string slides respectively to be fastened in two rope grooves.Rope groove has position-limiting action to tie string, and tie string is avoided to skid off outside worm gear.
Further, hoisting rope is equipped with suspension hook.It can be hung on lifting lug using suspension hook when hoisting rope is fixed on lifting lug
Mode, operate it is more convenient.
