Abstract
The utility model is a kind of new type explosion proof well lid; including the borehole wall and its wind cave; the fixing end of the well lid at well head, steel cable and connection steel cable and well lid, well lid is connected by pulley with weight; there is a central shaft at well lid center; allow that two halves well lid is pivoted, when being impacted, well lid two halves can be rotated up due to the influence of blast; play a part of to discharge pressure, so as to protect ventilation blower to be not damaged by.The Antiexplosive manhole cover is single due to forms of motion, is only capable of being pivoted, and more can accurately and quickly reset.Due to effectively discharging pressure, so as to prevent well lid to be flown by excessive pressure top and cause personal injury and the generation of property loss problem.Well lid peripheral lower edge is downwardly projecting and with balata belt, well lid is buckled on well head securely, improves sealing property.
Description
Technical field
The utility model is a new type explosion proof well lid, and specially one kind prevents that pressure is excessive to be caused well lid to be hit to fly and can be fast
The well lid of fast parking position accuracy.
Background technology
At present, traditional mining well lid is mostly hat type Antiexplosive manhole cover, mainly by conical Antiexplosive manhole cover, pulley, balance
Weight, sealed liquid cell and support are constituted.When divulging information normal, well lid can be made to be buckled on well head, make ventilation blower normal work,
When ventilation blower is stopped, can also automatically open up and be connected with atmospheric pressure, with certain draught capacity, if underground occurs gas thing
Therefore, the immense pressure of generation can also make well lid be opened, and play a part of release, make ventilation blower without damage, but traditional
Hat type Antiexplosive manhole cover has obvious shortcoming, and when underground occurs gas accident, the air pressure of bad student is very huge, so that explosion-proof well
Lid may be blown up, it is impossible to reset, and the well lid blown up is likely to cause property and personal injury, and sealing sealing fluid
It is required for re-replacing after well lid is blown up with well lid, increased the cost for using.
Utility model content
In order to make up the shortcoming of traditional Antiexplosive manhole cover, the utility model is a kind of new type explosion proof well lid.
The technical scheme of solve problem is as follows：The utility model Antiexplosive manhole cover, including wind cave and the borehole wall, the well at well head
Lid, well lid center axle links the fixing end of steel cable, pulley and weight on well lid, the two halves of well lid can be rotated up around central shaft,
It is easy to Rapid reset, and different working conditions can be tackled by the weight that pulley is connected from well lid.
Further, the lower end at well lid edge has rubber leather strap, effectively increases the sealing property of Antiexplosive manhole cover.
Further, lid Antiexplosive manhole cover is circle.
The beneficial effect of the utility model：The utility model is being to revolve upwards by enormous impact force due to two halves well lid
Turn, can effectively lay down pressure and the problem that well lid is blown up will not occur.Because the forms of motion of well lid is single, can be compared with
It is fast and reset exactly, it is ensured that the stabilization and reliability of ventilation.Due to the presence for having rubber leather strap at the protrusion of well lid lower end, make
The sealing of ventilating system is improved.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is front view of the present utility model
Fig. 2 is top view of the present utility model
1 wind cave in Fig. 1,2 weights, 3 pulleys, 4 fixing ends, 5 central shafts, 6 steel cables, 7 well lids, 8 rubber leather straps, 9 boreholes wall.
Specific embodiment
A kind of new Antiexplosive manhole cover as depicted in figs. 1 and 2 includes wind cave (1), the borehole wall (9), the well lid at well head
(7), through the central shaft (5) at this, steel cable (6), pulley (3), weight (2), the fixing end (4) of weight, well lid are connected on well lid
(7) has rubber leather strap (8) in edge lower end.If well lid (7) receives the enormous impact ripple of gas accident generation, the two of well lid
Half can significantly reduce borehole pressure around central axis, while the well lid for rotating up also has laid down most power, no
The phenomenon that well lid is blown up can occur.
The utility model without effectively reducing the risk that well lid is blown up, and because well lid forms of motion is single, can
With accurate and relatively rapid reset.The rubber leather strap of well lid lower end also ensure that the sealing property of ventilating system.
Claims (2)
1. a kind of new type explosion proof well lid, including wind cave (1), the well lid (7) at the borehole wall (9) and well head, by well lid center
Heart axle (5), connects the fixing end (4) of steel cable (6), pulley (3) and weight (2) on well lid, the edge lower end of well lid (7) has rubber
Rubber bar (8), can effectively improve the sealing of well lid, and the half part of well lid (7) two can be rotated up around central shaft (5), by cunning
The weight (2) that wheel (3) is connected from well lid (7) can tackle different working conditions.
2. a kind of new type explosion proof well lid according to claim 1, it is characterised in that：The well lid is circle.
