Detailed description of the invention
As depicted in figs. 1 and 2, hydraulic anti-theft well lid comprises well lid 2, walling crib 1 and the hydraulic lock mechanism 3 for locking well lid, well lid 2 is connected by bearing pin 7 with walling crib 1, hydraulic lock mechanism 3 is arranged on bottom well lid 2 and is integrated by being threaded, the petroleum pipeline 4 that described hydraulic lock mechanism 3 comprises hydraulic jack and is connected with oil cylinder, cylinder wall is provided with the tapered end 8 and the tapered end back-moving spring 11 that are extruded movement by piston 9, be provided with the spring that driven plunger resets in oil cylinder, well lid be also provided with the oiling stopple of the oil filler point 5 and shutoff oil filler point 5 be communicated with petroleum pipeline 4.For opening conveniently, be designed with two between well lid and walling crib for pushing the hydraulic air spring 6 of well lid open.
As shown in Figure 2, the sidewall of described oil cylinder piston 9 is provided with the breach on band inclined-plane, tapered end 8 rear end is in this breach, in order to make tapered end freedom of movement add roller 10 between itself and piston contact of incline plane face, when piston 9 moves, roller rolls along the inclined-plane of piston side wall, and during oil-feed, hydraulic oil promotes piston compression spring, tapered end bounces back under the action of the spring simultaneously, open tapered end, during draining, piston produces mobile under the promotion of spring, and piston slope driving tapered end is again locked.
As shown in Figure 3, key reaction engagement mechanism, described tapered end 8 front end is truncated cone-shaped, and the lockhole be opened in walling crib is the bellmouth matched with tapered end shape, enables well lid and walling crib closely cooperate during locking.
Well lid of the present invention and walling crib detailed drawing as shown in Figure 5, described well lid profile is reverse frustoconic, walling crib inwall is the truncated cone-shaped matched with well lid profile, it is taper fit between well lid and walling crib, can coordinate closely when well lid and walling crib locking, be provided with cannelure bottom walling crib, cannelure, built with damping seal ring 14, makes overall structure have the functions such as good water proofing property, shock resistance, dust-proof, anti-silt.
As shown in Figure 6; being arranged on the oil filler point 5 that well lid is communicated with petroleum pipeline 4 is bellmouth, and the oiling stopple corresponding with it is taper bolt, is provided with the internal thread hole caved in taper bolt; taper bolt inserts the operation playing protection oil filler point in well lid bellmouth, needs to be extracted with pin removal when extracting.
With reference to figure 7, described pin removal end is provided with internal thread hole 12 equally, pin removal is also set with sliding sleeve 13, sliding sleeve can slide along pin removal cylinder, during open manhole cover, hand grasps the sliding sleeve of pin removal, by stud or full flight screw, the internal thread hole of pin removal end is connected with the internal thread hole in taper bolt, so by pin removal, taper bolt is extracted.
When opening well lid, first extract the taper bolt on oil filler point 5 with pin removal, as Fig. 4, connect oil filler point and the high pressure hand hydraulic pump output interface a of petroleum pipeline 4 with high pressure consistent lubricant pipe, to hydraulic lock mechanism 3 oiling, lock is opened by high pressure hand hydraulic pump again, now just can open well lid; Open the oil drain valve of high pressure hand hydraulic pump after covering well lid, hydraulic pump is also provided with hydraulic pump and assists delivery outlet b, and when auxiliary delivery outlet b is for preventing output interface a mouth from blocking, high pressure hand hydraulic pump cannot use and the mouth for subsequent use that arranges.Piston produces mobile under the promotion of spring, piston slope driving tapered end is again locked, tapered end due to hydraulic lock mechanism 3 is pyramidal structure, and the lockhole in walling crib is also pyramidal structure, tapered end and lockhole are under the effect of tapered slope when locked, well lid is fixed in walling crib firmly, in conjunction with tight.Lay down the high pressure consistent lubricant pipe of high pressure hand hydraulic pump from well lid, again strike taper bolt, pack up high pressure hand hydraulic pump and pin removal, opener is separated with well lid, and integrated model has good theftproof performance.
Prior art is in this many well lid research, also there is no a technology using hydraulic system as research direction, the present invention compensate for this field, this anti-stealing manhole cover can be widely used in city down-hole power cable work raceway groove, good effect is played to guarantee power cable safety and life property safety of people, meanwhile, also can be applicable to the raceway groove of other industry, application prospect is boundless.
