Description

Emergency manhole cover

Technical Field

The utility model particularly relates to an emergency manhole cover applied to an inspection well.

Background

With the development of urban areas in China, more and more inspection wells in the urban areas have more and more potential safety hazards, after the well covers are stolen and damaged, the inspection wells losing the well covers often have accidents of falling pedestrians, and once the pedestrians fall into the inspection wells, the pedestrians are injured lightly and lose lives heavily. Because the well lid is changed to the loaded down with trivial details construction, and the time is long, in order to reduce danger, need carry out effectual shielding to the inspection shaft earlier in order to reduce danger, does not have the emergent shielding device of specialization at present, can't be quick effectual shielding to the inspection shaft.

Disclosure of Invention

The utility model aims to solve the defect that no specialized inspection well emergency shielding device exists at present and can not quickly and effectively shield the inspection well, and provides an emergency well cover which can conveniently shield the inspection well and has good safety performance.

The utility model is realized by the following technical scheme:

namely, an emergency well lid is characterized by comprising a cover body, wherein a vertical downward screw rod is arranged at the center of the lower end of the cover body, a screw rod hole matched with the screw rod is arranged at the center of the cover body, a concave rotating jack is arranged at the upper end of the screw rod, a nut is sleeved on the screw rod, a plurality of vertical support posts which are distributed uniformly and circumferentially are arranged uniformly are arranged on the lower end surface of the cover body, the lower end of each vertical support post is hinged with a fixing rod through a pin shaft, the fixing rods are uniformly distributed radially, and the inner end of each fixing rod is hinged with the nut.

As a preferred embodiment of the present utility model: the upper end of the screw rod penetrates into the central hole of the cover body, and the top end of the screw rod is flush with the upper end surface of the cover body. The lead screw penetrates into the central hole of the cover body, so that the function of sealing the central hole can be achieved.

The cross section of the rotary socket of the present utility model is preferably, but not limited to, a regular polygon. The screw rod can be conveniently rotated.

As a preferred embodiment of the present utility model: the fixed rod is provided with 3. Other numbers of fixing rods can be arranged as required.

The edge of the cover plate is of a wedge-shaped structure. The edge of the cover plate adopts a wedge-shaped structure, so that the lateral impact on the well cover caused by the vehicle driving over the well cover can be effectively reduced.

The utility model is provided with the matched crank, and the section of the front end of the crank is matched with the section of the rotary jack.

The nut is initially positioned at the upper part of the screw rod, the fixing rod is in a retracted state like an umbrella rib of an unopened umbrella, when an emergency shielding is needed for the inspection well, the cover body is covered on the inspection well, then the screw rod is rotated by the crank, the nut moves downwards along the screw rod, the fixing rod is gradually opened when the nut moves, and when the fixing rod contacts with a well wall of the inspection well, the cover body can be firmly fixed on the inspection well to play an emergency shielding role. When the emergency well lid needs to be dismantled, the fixing rod can be retracted by reversely rotating the screw rod.

The folding and unfolding process of the fixing rod is the same as that of an umbrella in the prior art.

The cover body of the utility model is provided with an opening hole as well as the well cover in the prior art.

The cover body of the utility model is square, round or any other well cover shape known.

The utility model has the advantages of reasonable structure and flexible and convenient use. By using the utility model, the inspection well which is lost and damaged can be quickly and effectively shielded, the working efficiency is greatly improved, and the safety is enhanced.

Detailed Description

As shown in fig. 1, 2 and 3: the edge of circular shape lid 1 is wedge structure, its bottom surface central point puts and is equipped with lead screw 3, the upper end of lead screw 3 pierces into the centre bore of lid 1, the top of lead screw 3 is equipped with the regular hexagon of indent and rotates jack 6, the up end of the top Yu Gai body 1 of lead screw 3 flushes, the cover is equipped with nut 4 on the lead screw, nut 4 is triangle-shaped, the inner end of three dead lever 5 all articulates with nut 4, three dead lever 5 is radial evenly distributed, the middle part of three dead lever 5 still articulates with vertical pillar 2 respectively, vertical pillar 2 partition circumference distribution.

In the utility model, in the initial state, the nut 4 is positioned at the upper part of the screw rod 3, the fixing rod 5 is in a retracted state, when the inspection well needs to be emergently shielded, the cover body 1 is covered on the inspection well, after the position is adjusted, the front end of the crank is inserted into the rotary jack 6, the screw rod 3 is rotated, the nut 4 moves downwards along the screw rod 3, the fixing rod 5 is gradually spread when the nut 4 moves, and when the fixing rod 5 contacts with the well wall of the inspection well, the cover body 1 can be firmly fixed on the inspection well to play the role of emergency shielding. When the emergency well lid needs to be dismantled, the screw rod is reversely rotated to retract the fixing rod, and the emergency well lid can be taken away by using the opening hole 7 and a corresponding tool (hook).

The present utility model is not limited to the above embodiments, and the cover may be square or other shapes, and the number of fixing bars may be changed.
