Detailed Description

The following description of the embodiments with reference to the drawings is intended to illustrate the present invention in further detail, such as the shapes and structures of the components, the mutual positions and connections between the components, the functions and working principles of the components, the manufacturing process, and the operation and use methods, etc., so as to help those skilled in the art understand the present invention more completely, accurately and deeply.

The overhaul of the equipments mouth is equipped with left socle 6 and right branch frame 5, the manhole door is used for the shutoff maintainer, the main part of manhole door is door closure 1, generally speaking, overhaul mouth and door closure 1 are circularly, door closure 1 is preferably the spherical crown structure, can promote door closure 1's compressive property like this, door closure 1 inboard is equipped with the closing plate, be equipped with the filling layer between closing plate and the door closure 1, the filling layer can further ensure the reliability of manhole door, and can be according to separating the temperature, the material of filling layer is selected to needs such as anticorrosive. In addition, the access hole outer peripheral face is equipped with

round seal ring

11, and 1 outer peripheral face of door closure is equipped with round closed groove, and when 1 closure of door closure was on the access hole, seal ring 11 was embedded into the closed groove to further ensure 1's of door closure sealing performance, seal ring 11 was fixed on equipment, and its protrusion also conveniently is changed sealed in equipment.

The both sides of overhaul of the equipments mouth are equipped with left socle 6 and right branch frame 5, as shown in fig. 1, 2, are equipped with the pivot 8 of vertical setting on the right branch frame 5, and pivot 8 is 1 pivoted main shaft of door closure, and it can rotate along

right branch frame

5, 3 one end of connecting rod and 1 rigid couplings of door closure, the other end and 8 rigid couplings of pivot, then door closure 1 uses pivot 8 to rotate as the axis, realizes the switching of access hole. Because the door closure 1 is of large mass, in order to ensure the supporting reliability of the door closure 1, the top end of the rotating shaft 8 is fixedly connected with the connecting rod, the reinforcing connecting rod 9 extends to the door closure 1 and is fixedly connected with the door closure 1, and the double fixing points are fixedly connected, so that the door closure 1 can be reliably fixed on the rotating shaft 8.
