Description

Plug-in strip maintenance scaffold
Technical field
Utility model relates to a kind of high voltage installation maintenance scaffold, relate in particular to a kind of in narrow and small and place, particularly Jian Xiu plug-in strip that can not unsettled maintenance aloft the plug-in strip in centre overhaul scaffold.
Background technology
The confession transformer station that power industry, particularly high-voltage electrical equipment are concentrated, power plant, booster stations etc., electric equipment repair and maintenance or replacing are as maintenance such as porcelain bottle cleaning, plug-in strips.These need overhaul parts not only in the eminence of high voltage installation, and are positioned at the equipment center position, and it is bigger, dangerous big therefore to overhaul difficulty.To the maintenance of this type of power equipment, be divided into interruption maintenance and charged equipotential maintenance dual mode usually at present, charged equipotential maintenance, so method is dangerous big, non-last resort is not adopted usually.Therefore and interruption maintenance is safest maintenance, and class place circuit, equipment are comparatively intensive again, each electrical equipment arrange and spacing not quite identical again, not only the space, place is little, and the top high-voltage line is intensive, the lift work car is difficult to directly enter hanging operation; And maintenance procedure do not allow again to take by electric equipment with ladder, so ladder is out of use.So in the prior art, general more employing is to take to put the scaffold maintenance, put the maintenance scaffold yet take, not only take and be set to this greatly, the consumption worker is consuming time, and repairing frame careless slightly damage that will cause electric fixtures in taking the process of tearing open, and touching closes on electric equipment arranged, and personal safety is constituted a serious threat.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of high pressure plug-in strip maintenance that can be used for is provided, and is simple in structure, the convenient use, and the plug-in strip that can enter narrow and small place overhauls scaffold.
Technical scheme according to the utility model provides at the upper end of insulating support installation work platform, in the lower end of insulating support fixed frame, is provided for locking the locking device of underframe on underframe.
Be provided in the upper end of insulating support the pegging graft coupling sleeve of connecting rod has connecting rod in coupling sleeve, be provided for the snap close of fastening the safety belt on connecting rod.
Groove is set on underframe, on the notch of groove, locking device is set.Locking device is a threaded connector, and the screw rod in this threaded connector passes the through hole on two sidewalls that form groove, and the handle of being convenient to tighten this screw rod is set on threaded connector.Locking device is a shackle member, and the pull bar in the shackle member passes the through hole on two sidewalls that form groove, at an end of pull bar buckle is set.
At the diagonal brace that is provided for improving intensity on the working platform and between the insulating support.Slipmat is set on working platform.
The utility model has the advantages that: on the channel-section steel of plug-in strip body basis, fixedly install insulating ladder, fix an insulating bar on the merogenesis coupling sleeve on top, left side, when the people worked at inspection platform, safety belt buckled into snap close, so not only safety but also reduce the volume occupy-place.Said plug-in strip base for supporting upper pillar stand connector, main effect be connect, fixing top insulating ladder, it can be socket joint groove (comprising long straight trough or deep-slotted chip breaker), also can be the socket joint pin, can make socket joint setting of insulation column or hinged setting.Can reach like this equipment repair and maintenance, support some connectors on the base plate, can make plug-in strip maintenance scaffold be in diverse location, the equipment each several part be overhauled to adapt to according to the maintenance needs.Support the fixing of base plate, can directly be fixed on the supporting traverse of institute's repair apparatus (on the channel-section steel of plug-in strip body basis).
For strengthening the steadiness of vertical insulation column, reduce the top platform of standing and rock, it is firm oblique rope to be set, and also can add the bearing diagonal that connects the insulation column supporting the base plate front.
Characteristics of the present utility model are: rational in infrastructure, novel, the light and handy volume of equipment is little, take and tear open conveniently, vertically is not with conducting metal.Maintenance person is stood on it can the close contact repair apparatus, can conveniently overhaul, safeguard, change centre, plug-in strip equipment top parts, has made things convenient for maintenance.Because of vertically thickness is less, shared ground is less, can directly enter electric equipment near reaching narrow and small place upkeep operation, be particularly useful for plug-in strip repair and maintenance or replacing that high-voltage electrical equipment is concentrated for transformer station, power plant, booster stations etc., greatly facilitate maintenance, having overcome existing device and be difficult in the convenient shortcoming of overhauling in appeal place, is the desirable repair apparatus in aforementioned place.
Description of drawings
Fig. 1 plug-in strip maintenance scaffold.
The specific embodiment
At the upper end of insulating support 3 installation work platform 5,, on underframe 2, be provided for locking the locking device 1 of underframe 2 in the lower end of insulating support 3 fixed frame 2.During use, underframe 2 is fixed on the fixed support of electric fixtures, with locking device 1 locking, operating personnel climb on the working platform 5 by insulating support 3, and relevant electric equipment such as plug-in strip etc. are overhauled again.
Be provided in the upper end of insulating support 3 the pegging graft coupling sleeve 4 of connecting rod 8 has connecting rod 8, the snap close 7 that is provided for fastening the safety belt on connecting rod 8 in coupling sleeve 4.When operating personnel stand on the working platform 5,, safety belt on one's body can be tied up on the snap close 7 for fear of security incident such as occurring dropping.
On underframe 2, groove is set, locking device 1 is set on the notch of groove.During installation, the notch of groove is straddled on the crossbeam of electric equipment, utilize locking device 1 locking again.
Locking device 1 can be as shown in Figure 1 threaded connector, the screw rod in this threaded connector passes the through hole on two sidewalls that form groove, and is welded on the sidewall nut outside and cooperates, setting is convenient to tighten the handle of this screw rod on threaded connector.Be placed on the crossbeam of electric equipment when underframe 2 upper grooves after, turning handle tightens together screw rod and nut.
Locking device 1 is a shackle member, and the pull bar in the shackle member passes the through hole on two sidewalls that form groove, at an end of pull bar buckle is set.This shackle member is easier than above-mentioned screw element when operation, during use, one end of pull bar is passed through hole on the sidewall, end at pull bar has a circular protrusions that is similar to flange usually, this protruding diameter is greater than the diameter of through hole, the end of pull bar is stuck on the through hole, at the other end of pull bar buckle is arranged, this buckle can cooperate with the fastener on being arranged at underframe 2.
On the working platform 5 and be provided for improving the diagonal brace of intensity between the insulating support 3.Slipmat 6 is set, in order to avoid the staff falls down on working platform 5.
