Detailed description of the invention
Referring to drawings and Examples, the utility model is described in detail:
Accompanying drawing 1-3 is known, and a kind of regularization can face hole, limit guard rail by open and close type,
Comprise hole guard rail and opening and closing device;
Described opening and closing device comprises the fixed bearing 1 be arranged on the left of hole; Described holder 1 is two, arranges along hole vertical direction;
Holder 1 is equal leg angle; The horizontal plane of described equal leg angle is arranged on top, and vertical plane is provided with installing hole; Equal leg angle vertical plane is connected with jamb 3 by expansion bolt 2;
The horizontal plane of equal leg angle is vertically provided with axis of rotation 4;
The rectangular frame that hole guard rail is made up of horizontal beam 5 and vertical beam 6; Longeron 7 and screen cloth 8 is provided with in described rectangular frame;
Turnbarrel 9 is set with outside described axis of rotation 4; Described turnbarrel 9 is connected with the vertical beam 6 on the left of the guard rail of hole;
In the middle part of the guard rail of hole and bottom is provided with baffle plate 10; The right side of described baffle plate 10 is provided with fairlead 11; Bolt rod 12 is provided with in described fairlead 11; Described bolt rod 12 right-hand end is arranged in plug housing 13; Described plug housing 13 is fixedly connected with side, hole 3 wall.
Described equal leg angle is the equal leg angle of ∠ 5 × 5.
Described axis of rotation diameter is 15-20 millimeter; Described axis of rotation length is 70-90 millimeter.
Described bolt rod diameter is 10-15 millimeter.
