The specific embodiment

Sincerely see also Fig. 1 to 3, the utility model provides the structure of a kind of people, hand hole cover opening/closing device, comprises basic building blocks such as pedestal 10, strut group 20, oil pressure jacking device 30, wherein:

Pedestal 10 is one to be the pipe support 11 of frame shape, and each below, corner of frame shape is equipped with roller 15, wherein the 11 inboard ends of an end longer pipe frame, be provided with two relative slide rails 12 along the place, then be provided with a sleeve pipe 13 that can stretch into pipe support 10 inside at the other end, wherein be bordering on pipe support 11 and sleeve pipe 13 joining places, be provided with lug 14 in pipe support 11, and it is fixing for sleeve pipe 13 to be provided with bolt button 16 at lug 14 sides;

Strut group 20 is made up of several inside and outside

bar sheets

21,22 and is cut shape, and the fulcrum of inside and outside

bar sheet

21,22 and end points are equipped with a needling 23, the outside, wherein interior bar sheet 21 bottoms knot is provided with guide wheel 24, then establish with lug 14 bolts of pedestal 10 pipe supports 11 outer bar sheet 21 bottoms, and it is solid with oil pressure jacking device 30 motion ends knot then to be provided with sleeve pipe bolt 25 at place, interior bar sheet 21 bottoms, and wherein the needling 23 of these inside and

outside bar sheet

21,22 upper ends is provided with cable wire 26;

Oil pressure jacking device 30 is a hydraulic jack, is set up in pedestal 10 side inner faces and fixes, and its bottom is provided with a jack 31, inserts in conjunction with flexible with the actuating strut 33 of controlling oil pressure jacking device 30 motion ends for an action bars 32;

With pipe support on the pedestal 10 11 and sleeve pipe 13 unclasping with bolt button 16, make sleeve pipe 13 be stretched to predetermined length, this length then needs greater than desiring the opener, the length of hand hole cover 40, thereafter bolt button 16 is rotated with, the distance of 11 of sleeve pipe 13 and pipe supports is fixed, drive whole displacement in the people using the roller located below pedestal 10 each corner 15, on the hand hole cover 40, the side makes the cable wire 26 and the people of needling 23 in the strut group 20, hand hole cover 40 propose hole 41 combinations, when the time comes, action bars 32 combines with the jack 31 of oil pressure jacking device 30 and back and forth swing action back and forth, even its actuating strut 30 promotes the needling 23 of bar sheet 21 lower ends in the shore group 20, this needling 23 then moves on slide rail 12 by guide wheel 24, impel in the strut group 20,

outer bar sheet

21,22 angles change and rise, in promptly being somebody's turn to do, the needling 23 of outer bar sheet 21 upper ends drives cable wire 26 and rises, and then with the people, hand hole cover 40 promotes in pedestal 10 belows and locatees, and carried the people who opens with pedestal 10 is related, hand hole cover 40 is used roller 15 and is pushed its pedestal 10 open, makes the operating personnel must be in the people, construction in the hand hole; Otherwise desire is with the people, when hand hole cover 40 resets, then pedestal 10 is pushed back the beginning position, and use oil pressure jacking device 30 and release oil action, the weight that makes actuating strut 33 use sleeve pipe bolt 25 and people, hand hole cover 40 must make strut group 20 descend, and people, hand hole cover 40 can reset and cover; Because oil pressure jacking device 30 of the present utility model is because of the architecture design of strut group 20, impel oil pressure jacking device 30 to be set up in by pedestal 10 sides, operator human foot place is not needed near people, hand hole cover 40, and then in people, hand hole cover 40 opening-closing processes, more can guarantee its operational security.
