Technical scheme of the present invention is achieved in that a kind of inlet wire electrical verification ground connection handcart of going up, comprise base, it below the base roller, above the base support and panel, fixedly electrical verification contact arm and high pressure sensor on support, it is characterized in that: electrification display is arranged on panel, ground connection interlocking device is set on support.
Described ground connection interlocking gear comprises that one is fixed on operation disk on the support, operation disk outside fixing operation handle by rotating shaft; A pilot hole is set on the base, gear-stopping bar is installed in the pilot hole, the upper end of gear-stopping bar is connected with bearing pin and operation disk are inboard by connector; A ground connection cutter head is fixed by bearing pin in the position of ground connection tool rest correspondence on the support of operation disk upside, fixes a pull bar at operation disk upside by bearing pin, and the upper end of pull bar is connected with the ground connection cutter head by bearing pin; The voltage extracting terminal of the high voltage variable light current on described electrification display and the high pressure sensor is electrically connected, and one pair of normally closed node is arranged in the electrification display, and the handle electromagnetic locking mechanism of setting on normally closed node and the panel is electrically connected.
Described handle electromagnetic locking mechanism comprises lock hole, the location hole on the operation disk and the electromagnetic lock of lock handle on the handle.
At base location handgrip and alignment pin are set, behind the handcart push-on switch cabinet, handcart are pinned by location handgrip and alignment pin.
The present invention compared with prior art has following advantage: 1, integrate electrical verification, grounding function, operate practical and convenient; 2, the three-phase electrification display is installed on the handcart panel, electricity is arranged, do not have electricity to observe intuitively; 3, behind the handcart push-on switch cabinet, the fixed contact in electrical verification Mume flower contact and the switch cubicle closely contacts good reliability; 4, be provided with ground connection interlocking between earthed switch and the handcart roller, when earthed switch is in when closing, roller is stuck, can't the push-on switch cabinet, satisfy machinery five anti-requirements; 5, panel is provided with the earthed switch operating grip, rapid operation, convenience; 6, behind the handcart push-on switch cabinet, by location handgrip and alignment pin handcart is pinned, electrical verification, ground connection are reliably firm; 7 handcarts are applicable to the electrical verification and the ground connection of end of incoming cables on the switch cubicle.

Embodiment
The present invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of inlet wire electrical verification ground connection handcart of going up, comprise base 17, it below the base 17 roller 11, above the base 17 support 18 and panel 14, fixedly electrical verification contact arm 19 and high pressure sensor 1 on support 18 have electrification display 13 on panel 14, ground connection interlocking device is set on support 18.Described ground connection interlocking gear comprises that one is fixed on operation disk 8 on the support, operation disk 8 outside fixing operation handles 3 by rotating shaft; A pilot hole 10 is set on the base 17, gear-stopping bar 12 is installed in the pilot hole 10, the upper end of gear-stopping bar 12 is by connector 9 and bearing pin and 8 inboard connections of operation disk; A ground connection cutter head 2 is fixed by bearing pin in the position of ground connection tool rest 6 correspondences on the support 18 of operation disk 8 upsides, fixes a pull bar 7 at operation disk 8 upsides by bearing pin, and the upper end of pull bar 7 is connected with ground connection cutter head 2 by bearing pin; The voltage extracting terminal of the high voltage variable light current on described electrification display 13 and the high pressure sensor 1 is electrically connected, and one pair of normally closed node is arranged in the electrification display 13, and the handle electromagnetic locking mechanism of setting on normally closed node and the panel is electrically connected.Described handle electromagnetic locking mechanism comprises lock hole 5, the location hole 21 on the operation disk and the electromagnetic lock 4 of lock handle on the handle.At base 17 location handgrip 16 and alignment pin 15 are set.
Mechanical interlocking operation principle: when operating grip 3 pushes away from bottom to top, drive pull bar 7 by operation disk 8 and move upward, connect by ground connection cutter head 2 and ground connection tool rest 6.While disk operating mechanism 8 also drives gear-stopping bar 12 and moves downward by pilot hole 10, is inserted on the switch cubicle body ground connection interlocking hole.Thereby the handcart roller can't travel forward when making earthed switch close, effectively prevents charged mistake splice grafting ground switch.At this moment, earthed switch is in ground state, and electricity is arranged again in the switch cubicle, should be strictly on guard against in the electrical verification ground connection car push-on switch cabinet, causes the serious consequence of charged splice grafting ground switch.The electrical interlock operation principle: the voltage extracting terminal of a high voltage variable light current is arranged on the high pressure sensor 1, go between to high-voltage charge display device 13, this electrification display is mounted on the handcart panel, height is pressed with, then electrification display is lighted, and is very directly perceived, 13 interior one pair of normally closed node in addition, go between to electromagnetic lock 4, when high pressure did not have electricity, this node was connected, and made the turn left limit withdrawal of electromagnetism lock core, lock hole 5 on the release lever, operating grip 3 allows operation.When height was pressed with electricity, this node became battle, and the electromagnetism lock core ejects to the right because of losing electromagnetic force, and the lock hole 5 that inserts on the handle makes its locking, and operating grip 3 can't rotate, thereby reaches the electrical interlock purpose.At this moment, after earthed switch is opened, but electrical verification in the handcart push-on switch cabinet when electricity, should be forbidden splice grafting ground switch.
