Description
Technical Field
The utility model relates to a communication equipment field especially relates to a communication pipeline manhole cover device of uncapping.
Background
The communication pipeline consists of a manhole or a hand hole and a pipe hole, wherein the manhole or the hand hole consists of an outer cover, a sub-cover, a mouth ring, an oral cavity and the like, the outer cover is embedded in the mouth ring, the sub-cover is arranged below the outer cover, and the sub-cover is placed on a platform in the mouth ring. The outer cover is made of nodular cast iron generally, the outer cover is heavy in weight, particularly, the outer cover is a manhole outer cover positioned on a traffic lane, in order to ensure driving safety, a weighting type is generally adopted, and the outer cover is heavier in weight; the sub-cover is generally placed on a platform in the mouth ring, is relatively light in weight and is relatively easy to open.
Under the normal condition, a constructor penetrates into an opening hole of a manhole outer cover by using a manhole cover hook, hooks the outer cover, lifts upwards by using force, can pull out an outlet ring of the outer cover, pulls the manhole cover hook by using force, can pull the outer cover to one side of a manhole opening, and lifts the sub-cover to one side of the manhole opening by using a handle of a portable screwdriver cover. And the manhole cover is opened, and constructors can immediately carry out subsequent construction in the manhole.
Because the communication pipeline manhole or the hand hole is arranged underground, the environment is wet, and some outer covers which are not opened usually are corroded and adhered with the mouth ring, so that the opening difficulty is increased; the caliber of some mouth rings is smaller, and the outer cover is hooped in the mouth rings, so that the outer cover is extremely difficult to open; still some communications engineering are under construction in winter in the north, and the moisture that rises in the manhole meets the low temperature outside the manhole at manhole enclosing cover department for the manhole enclosing cover is frozen to death in the mouth circle, also causes the enclosing cover can't open.
For the above reasons, the manhole outer cover is not opened or is difficult to open. In the case of communication pipe work, construction work in a manhole cannot be performed without opening a manhole cover, and thus, it is necessary to try to open the manhole cover, which is difficult to open, before construction. In the traditional construction method, when a manhole outer cover which is difficult to open is met, a constructor often uses a hammer or a stone to forcibly smash the outer cover, shakes the outer cover to separate the outer cover from the adhesion of the mouth ring, or uses an ignition blowtorch to roast the contact part of the outer cover and the mouth ring, burns sundries or roasts frozen ice, then penetrates a manhole cover hook into an opening hole, forcibly pulls the manhole cover upwards, wastes time and labor, and even cannot open the manhole outer cover. Therefore, in order to ensure that the construction of the communication pipeline engineering can be carried out smoothly, the design of a simple and effective manhole cover opening device is urgent.
