Abstract
The invention discloses a high anti-violence type underground refuge chamber blast airtight door. The high anti-violence type underground refuge chamber blast airtight door comprises an airtight door body, wherein the back surface of the airtight door body is provided with multiple longitudinal reinforcing ribs which are arranged in parallel, the middle part of the airtight door body is provided with multiple first horizontal reinforcing ribs which are located in the same straight line, the upper part and the lower part of the airtight door body are both provided with multiple second horizontal reinforcing ribs which are located in the same straight line, and third horizontal reinforcing ribs are arranged between the first horizontal reinforcing ribs and the second horizontal reinforcing ribs; a grid type reinforcing rib framework is formed after the first horizontal reinforcing ribs, the second horizontal reinforcing ribs and the third horizontal reinforcing ribs are both welded on the longitudinal reinforcing ribs. According to the high anti-violence type underground refuge chamber blast airtight door disclosed by the invention, when the airtight door body suffers from an impact effect as a novel grid type reinforcing rib framework is formed by adding the using amount of steel in a tension zone at the other side of each reinforcing rib, the impact load can be effectively borne, and the undamaged structure of the airtight door body can be ensured.
Description
Technical field
The present invention relates to underground refuge chamber manufacturing technology field, relate in particular to a kind of high uprising type underground refuge chamber airtight blast door.
Background technology
In coal production process, there is the threat of the objective factors such as water, fire, gas, coal dust, top board in down-hole all the time, and the new Dangerous and Harmful Factors such as underground heat, corrosive substance, radioactive substance have also appearred in part mine.May there is high temperature, high humidity, high dust from flying, high gas density, corrosive gas in these regional environments, cause that calamity factor is many, danger classes is high, and the danger that catastrophe occurs is very large.
Country issue emergent danger avoiding system under shaft of coal mine implementation management temporary provisions according to < < State Council notice > > (No. (2010) 23, the promulgated by the State Council) spirit about the work of further reinforcement enterprise safety operation, formulate this regulation.Strengthened the requirement that adds of safety supervision and rescue equipment.As underground emergency danger-avoiding facility, in rescue equipment, refuge chamber is the equipment facility that emphasis is promoted, refuge chamber can be escape personnel a confined space that ensures life security is provided, airtight blast door as the first outpost of the tax office-refuge chamber of life support, direct relation the life security that enters staff after refuge chamber, can wait for rescue personnel to arrive, the first guarantee of safe escape mine disaster, externally can resist blast impulse, resist high temperature, completely cut off toxic and harmful, for realizing rescue, play vital effect.
If existing underground refuge chamber protection airtight door will improve structural explode resistance ability, mainly with thickening door-plate materials, or reduce door-plate size, or add the modes such as gate panel back transverse and longitudinal rectangle reinforcing rib section area and realize, although also can improve certain impact resistance, but because steel using amount is large, exist product weight large, high in cost of production defect.
The disclosed underground refuge chamber airtight blast door of Chinese patent CN102900335A, it is disclosed in the 3rd groove of a body eight the first reinforcing ribs is set, two longitudinal arrangements, six are transversely arranged.By finite element analysis and the equal susceptible of proof of experiment, the tension side steel tension surrender inefficacy that airtight blast door is all door-plate rectangle reinforcing ribs by impact failure causes, therefore strengthen the tension side tensile property of door-plate reinforcing rib, most important for the impact strength that improves airtight blast door.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes a kind of high uprising type underground refuge chamber airtight blast door, simple in structure, on the basis that does not significantly increase steel using amount, strengthen the tensile property of reinforcing rib tension side, improve the impact strength of airtight blast door.
A kind of high uprising type underground refuge chamber airtight blast door that the present invention proposes, comprise sealed door body, at the sealed door body back side, be provided with the many walings that be arranged in parallel, many the first cross reinforcings that are located along the same line are set at the middle part of sealed door body, many the second cross reinforcings that are located along the same line are all set in the upper and lower of sealed door body, between the first cross reinforcing and the second cross reinforcing, are provided with the 3rd cross reinforcing; Waling, the first cross reinforcing, the second cross reinforcing and the 3rd cross reinforcing are all welded on sealed door body, and the first cross reinforcing, the second cross reinforcing and the 3rd cross reinforcing are all welded on and on waling, form grill-shaped reinforcing rib framework; Waling is along the vertical strip steel plate arranging of sealed door body, the first cross reinforcing comprises many first short strip shape steel plates that are located along the same line and the first T steel plate, the first short strip shape steel plate and the first T steel plate are disposed between waling, the second cross reinforcing is many second short strip shape steel plates that are located along the same line, and the 3rd cross reinforcing is many second T steel plates that are located along the same line.
Preferably, waling is equidistantly set in parallel in the back side of sealed door body.
Preferably, the first cross reinforcing equates with the spacing between the second cross reinforcing and the 3rd cross reinforcing with the spacing between the 3rd cross reinforcing.
Preferably, the first T steel plate, the second T steel plate form by stave sheet and horizontal steel plate, and stave sheet is welded on sealed door body, and doubly, stave sheet height is 1.3-1.6 times of horizontal steel plate height to the 0.3-0.6 that stave sheet thickness is horizontal steel plate thickness.
Preferably, strip steel plate, the first short strip shape steel plate, the second short strip shape steel plate equate with the thickness of stave sheet.
In the present invention, the thin riser of the first T-steel plate, the second T-steel plate is welded on sealed door body, thick transverse slat is located at outside, has good bending resistance tensile property; When sealed door body is subject to impacting, thick transverse slat stops grill-shaped reinforcing rib framework to lose efficacy, the tensile property of strengthening reinforcing rib tension side, the impact strength of raising airtight blast door.In the quantity and the position while that do not change reinforcing rib, cross reinforcing adopts T-steel plate to replace short strip shape steel plate, a small amount of rolled steel dosage that increases reinforcing rib opposite side tensile zone forms Novel grille shape reinforcing rib framework, make sealed door body when being subject to percussion, can effectively bear shock loading, and guarantee that sealed door body construction is intact.
Accompanying drawing explanation
Fig. 1 is the structure schematic diagram of a kind of high uprising type underground refuge chamber airtight blast door that proposes of the present invention.
Fig. 2 be in Fig. 1 A-A to sectional view.
