Description
Technical field
The utility model relates to a kind of high voltage installation maintenance scaffold, belongs to electric equipment service kit technical field.
Background technology
The maintenance of high voltage electric equipment is divided into interruption maintenance and charged equipotential to overhaul two kinds, charged equipotential maintenance danger is larger, therefore often adopt interruption maintenance, but because high voltage installation is generally in higher position, simultaneously comparatively intensive for the circuit in all kinds of place, equipment arrangement, therefore lift work car is difficult to hanging operation; In prior art, normal employing scaffolds erecting, and not only cost is higher, and easily damages electric equipment in work progress.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of high voltage installation to overhaul scaffold, convenient and practical, can overhaul at the higher position equipment of narrow space.
To achieve these goals, the high voltage installation maintenance scaffold adopted, comprise insulation underframe, job platform and Lifting scaffold, job platform is arranged on the top of insulation underframe, Lifting scaffold comprises the framework be fixed on bottom job platform, and frame facet has elevating rocker arm, and elevating rocker arm is connected with worm screw by key, worm screw forms primary transmission mechanism with the female worm gear of band, and the internal thread of worm gear and screw mandrel form secondary drive mechanism;
The top of screw mandrel is provided with scaffold mechanism.
The utility model adopts the scaffold mechanism of hand lifting, and realizes secondary transmission by worm-and-wheel gear, internal thread screw body, rotary motion is transferred to the lifting that rectilinear motion realizes scaffold mechanism.Two self-locking mechanism realizes the dual fail-safe of self-locking, and stable drive is reliable.
The insulation underframe of the left and right sides is hinged on the bottom of job platform, forms " people " font support when opening; The insulation underframe of both sides is the ladder that can climb.
Insulation underframe can be opened and close up, and makes the space shared by equipment less, is more applicable for the maintenance of the high-tension apparatus of small space; Insulation underframe is ladder, and convenient maintainer climbs up and down.
Also comprise bearing pin, framework and screw mandrel arrange the pin-and-hole matched with bearing pin.When Lifting scaffold move to touch position time, bearing pin is inserted the pin-and-hole that framework and screw mandrel are arranged, when screw mandrel running damages, the position of Lifting scaffold can be locked further, improve the safety of whole mechanism.
Scaffold mechanism comprises locking cover and is arranged on the supporting plate of locking cover both sides, and locking puts has safety belt.Scaffold mechanism is detachable, is convenient for carrying.
The leg place of insulation underframe has Anti-slip cover.
The utility model mechanism is simple, and compact, convenient disassembly, is more applicable for electric equipment and arranges compact small space.
Accompanying drawing explanation

Fig. 3 is that the A-A of Fig. 1 is to sectional view.
In figure: 1, insulate underframe; 11, Anti-slip cover; 2, job platform; 3, Lifting scaffold; 31, framework; 32, elevating rocker arm; 33, worm screw; 34, worm gear; 35, screw mandrel; 36, scaffold mechanism; 36-1, locking cover; 36-2, supporting plate; 4, bearing pin.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of high voltage installation maintenance scaffold, comprise insulation underframe 1, job platform 2 and Lifting scaffold 3, job platform 2 is arranged on the top of insulation underframe 1, Lifting scaffold 3 comprises the framework 31 be fixed on bottom job platform 2, and the side of framework 31 has elevating rocker arm 32, and elevating rocker arm 32 is connected with worm screw 33 by key, worm screw 33 forms primary transmission mechanism with the female worm gear 34 of band, and internal thread and the screw mandrel 35 of worm gear 34 form secondary drive mechanism;
The top of screw mandrel 35 is provided with scaffold mechanism 36.
The utility model adopts the scaffold mechanism of hand lifting, and realizes secondary transmission by worm-and-wheel gear, internal thread screw body, rotary motion is transferred to the lifting that rectilinear motion realizes scaffold mechanism.Two self-locking mechanism realizes the dual fail-safe of self-locking, and stable drive is reliable.
The insulation underframe 1 of the left and right sides is hinged on the bottom of job platform 2, forms " people " font support when opening; The insulation underframe 1 of both sides is the ladder that can climb.
Insulation underframe 1 can be opened and close up, and makes the space shared by equipment less, is more applicable for the maintenance of the high-tension apparatus of small space; Insulation underframe 1 is ladder, and convenient maintainer climbs up and down.
Also comprise bearing pin 4, framework 31 and screw mandrel 35 arrange the pin-and-hole matched with bearing pin 4.When Lifting scaffold 3 move to touch position time, bearing pin is inserted the pin-and-hole that framework 31 and screw mandrel 35 are arranged, when screw mandrel running damages, the position of Lifting scaffold 3 can be locked further, improve the safety of whole mechanism.
Scaffold mechanism 36 comprises locking cover 36-1 and is arranged on the supporting plate 36-2 of locking cover both sides, and locking cover 36-1 has safety belt.Scaffold mechanism 36 is detachable, is convenient for carrying.
The leg place of insulation underframe 1 has Anti-slip cover 11.
During work, insulation underframe 1 is opened formation " people " font, there is bottom job platform the open angle that position-limit mechanism can limit insulation underframe 1, Lifting scaffold 3 shakes to desired location by maintainer as required swinging handle, then climb and climbing up supporting plate to working platform, then fasten one's safety belt.Insulation underframe steadiness is good, is convenient to maintenance activity.
