detailed description

The present invention will be further described below in conjunction with specific drawings and embodiments.

As shown in Figures 1 to 3, it includes handrail 1, bottom beam 2, swing rod 3, ratchet rod 4, crank arm 5, telescopic arm 6, fan-shaped angle adjuster 7, insulating terminal 8, top beam 9, and jacking cylinder 10 , Hand double-ended screw rod 11, bracket block 12, trunnion 13, angle-adjusting telescopic shaft 14, etc.

As shown in Figures 1 to 3, the cable terminal test hydraulic support of a GIS cable pressurized air chamber of the present invention includes a bottom beam 2 with walking wheels installed at the four corners of the bottom, and a pull rod is hinged at the front end of the upper surface of the bottom beam 2. And the handrail 1 is set at the front end of the pull rod, the bottom beam 2 is connected with the swing rod 3 through the rotating shaft, the front end of the swing rod 3 is connected with the telescopic arm 6, the telescopic arm 6 is provided with a chute 6.1, and one end of the curved arm 5 passes through the slider Slidingly connected to the chute 6.1, the other end of the crank arm 5 is connected to the ratchet end of the ratchet lever 4, and the lower end of the ratchet lever 4 is hingedly connected to the bottom beam 2; the outer end of the telescopic arm 6 is hinged with a fan-shaped angle adjusting piece 7 , the top of the fan-shaped angle adjusting piece 7 is fixedly connected to the top beam 9, and a jacking oil cylinder 10 is respectively arranged at both ends of the top beam 9, and a supporting block 12 is connected to the end of the piston rod of the jacking oil cylinder 10.

The working surface of the support block 12 is V-shaped, and is used to support the trunnion 13 of the insulating terminal 8 .

A rack structure is formed on the upper surface of the telescopic arm 6 , and the rack structure is matched with a slider for connecting the crank arm 5 .

The connecting end of the crank arm 5 and the ratchet lever 4 is connected with a ratchet block, and the ratchet block is matched with the ratchet wheel of the ratchet lever 4 .

A plurality of circular adjustment holes 7.1 are uniformly arranged on the fan-shaped angle-adjusting piece 7 along the arc surface of the fan-shaped bottom, and the adjustment holes 7.1 cooperate with the limit posts on the telescopic arm 6 .

The bottom beam 2 of the product of the present invention forms a strip-shaped groove structure in the middle, and the swing rod 3 is folded in the strip-shaped groove of the bottom beam 2 when it is not working normally; when it is necessary to use the jacking cylinder 10 to lift the insulating terminal 8 , the swing link 3 rises from the bottom beam 2, and at the same time the crank arm 5 and the ratchet lever 4 are pulled up to support the swing link 3.
