Abstract
The utility model discloses a vertical shaft manhole cover, which comprises a shaft cover 7 and a cover door 1. The cover door 1 and the shaft cover 7 are connected by a cover door hinge 6, and a door crack sealing device 4 is arranged at the gap between the cover door 1 and the shaft cover 7. The door crack sealing device 4 is provided with two belts connected by a belt fastener or provided with a flexible strip, and two ends of the connected belt or the strip are fixed onto the shaft cover 7 and the cover door 1 respectively. A door spindle crack of the cover door is completely sealed without affecting opening and closing functions of the manhole cover door, and shaft falling objects at the door crack can be effectively prevented, so that effective safety construction is realized.
Description
Technical field
The utility model relates to a kind of vertical well lid, especially a kind of vertical well lid that can prevent to weigh down to pit shaft from crack between a door and its frame thing.
Background technology
In coal mine shaft lining sinking shaft work progress, it is extremely important that construction safety seems, and in the vertical safety management, prevent that pit shaft from weighing down the thing most important thing especially.At present, kibble hoist personnel and spoil are generally adopted in the construction of China's shaft sinking.The trapdoor of well head is closed at ordinary times, can pit shaft not occur from trapdoor and weigh down thing, but when well-bucket was come in and gone out well head, two fan trapdoors must be opened, and this moments two, the fan trapdoor was split.In the trapdoor rear and front end fence and baseboard are installed generally; Can think that these both sides are not prone to the fast or foreign material of gravelstone and weigh down down; But a crack between a door and its frame appears in the door-hinge place at trapdoor; If just in time have finger stone or other foreign material in ground this moment, crash into well head from crack between a door and its frame, the security incident that well head weighs down thing just appears.The utility model stitches complete closed to the door-hinge of trapdoor, and does not influence trapdoor switching function, can prevent effectively that the door-hinge seam from weighing down thing, the safety that has improved shaft construction.
Summary of the invention
The utility model technical problem to be solved provides a kind of vertical well lid that can prevent to weigh down to pit shaft from crack between a door and its frame thing.
The technical scheme that the utility model solves its technical problem is:
A kind of vertical well lid comprises closure plate and Gai Men, covers door and is connected through the lid door hinge with closure plate, locates to be provided with the crack between a door and its frame sealing device in the lid door and the slit of closure plate.Described crack between a door and its frame sealing device is with two sections belt leathers of bracelet connection or has flexible ribbon that the two ends of belt or ribbon are separately fixed on closure plate and the Gai Men.
Compared with prior art, the utility model opens and closes function and enough will cover the door-hinge of door and stitch complete closed not influencing trapdoor, and also has the following advantages:
1, simple in structure, stable performance, easy to maintenance, economy and durability;
2, applicability is strong, goes in the position and device of various needs sealing crack between a door and its frames;
3, material finds easily, and the materials used cost consumption is the end of than;
4, because belt is flexible rubber, do not influence the function of use that trapdoor opens and closes.
5, improve working conditions, prevent that effectively pit shaft weighs down thing at the crack between a door and its frame place, thus the effective and safe construction.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, a kind of vertical well lid comprises closure plate 7 and Gai Men 1, covers door 1 and is connected through lid door hinge 6 with closure plate 7, is provided with crack between a door and its frame sealing device 4 at the place, slit of lid door 1 and closure plate 7.Described crack between a door and its frame sealing device 4 is with two sections belt leathers of bracelet connection or has flexible ribbon that the two ends of belt or ribbon are separately fixed on closure plate 7 and the Gai Men 1.
