Abstract
The utility model discloses a colliding type wind tunnel door which comprise a bottom beam, a wind tunnel door frame, a wind tunnel doors, pulleys, positioning wheels, a steel cable, a gravity suspension drop and rubber wheels, wherein the wind tunnel door frame is internally provided with a pair of wind tunnel doors of an opposite opening type; the inner side and the outer side on the upper part of the inner border of the wind tunnel door are provided with a pair of the pulleys; the inner side and the outer side of the inner border on the upper parts of the pair of the pulleys are provided with the positioning wheels, and the inner border is of a hollow type; the steel cable is fixedly arranged on the wind tunnel door frame and extends downwards along hollow part of the inner border through pulley grooves of the pair of the pulleys, and the lower end of the steel cable is fixedly provided with the gravity suspension drop; the inner side and the outer side of the wind tunnel door are provided with the pair of the rubber wheels; and structures and configurations of a pair of the wind tunnel doors are completely symmetrical and same. The utility model has the characteristics of simple structure and reasonable design. The wind tunnel door can be automatically returned without guarding by specially-assigned persons, thereby being safe and reliable. Both vehicles and people can pass through the wind tunnel door. Vehicles pass through the wind tunnel door by flexible collision, thus the service life of the wind tunnel door is greatly prolonged.
Description
Technical field
The utility model relates to pit coal underworkings wind-tunnel door, refers more particularly to a kind of formula wind-tunnel door that rushes open.
Background technology
When in the tunnel, blowing, can deliver to farthest or bottom work plane under the coal mine, need the wind-tunnel door be set more than it or on the tunnel with nearly different level level, to prevent distinguished and admirable short circuit for guaranteeing fresh air.At present, the wind-tunnel door that the employing special messenger that the wind-tunnel door under the coal mine has guards can increase expense so undoubtedly, strengthens operating cost; The employing electrodynamic type wind-tunnel door that has, this wind-tunnel door complexity, the cost height, and can only cross car can not be remarkable; The employing lever impacting type wind-tunnel door that also has, vehicle by the time be rigid rushing open, the wind-tunnel gate pole is fragile.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of and can effectively overcomes the problems referred to above, and the wind-tunnel door can automatically reset, and need not the special messenger and guards, simple in structure be suitable for, both can cross car also can be remarkable, vehicle by the time be the flexible formula that the rushes open wind-tunnel door that rushes open.
The technical solution of the utility model is such, rushes open formula wind-tunnel door and comprises bottom girder, wind-tunnel every frame, wind-tunnel door, pulley, locating wheel, wire rope, the outstanding bob of gravity and rubber wheel;
Described bottom girder crosswise fixed is seated on the lower frame of described wind-tunnel every frame; Between the wind-tunnel every frame upper ledge and bottom girder in described wind-tunnel every frame both sides, be coated with a pair of described wind-tunnel door by door-hinge, a pair of described wind-tunnel door is an opposite opened; A pair of described pulley is equipped with in the inside and outside both sides on the top of the rim of described wind-tunnel door, and the outer rim of a pair of described pulley is near tangent; A pair of described locating wheel is equipped with in the inside and outside both sides of the described rim in a pair of described pulley top; Described rim is a hollow type, on the supermedial described wind-tunnel every frame of rim described wire rope is housed fixedly, and wire rope is by the wheel ditch of a pair of described pulley, and along stretching under the rim hollow bulb, the outstanding bob of described gravity fixedly is equipped with in its lower end; The middle and lower part of described wind-tunnel door is equipped with a pair of described rubber wheel near the inside and outside both sides of described rim by a pair of rubber tire frame; The structure of a pair of described wind-tunnel door and configuration be symmetry and identical fully; Pass described bottom girder on the lower frame of described wind-tunnel every frame a pair of rail vertically is housed.
The utility model is simple in structure, and is reasonable in design.The wind-tunnel door can automatically reset, and need not the special messenger and guards, and is safe and reliable.The wind-tunnel door not only can pass through vehicle, also can pass through the pedestrian.Vehicle by the time be that flexibility rushes open, prolong the application life of wind-tunnel door greatly.Be fit to installing and using under all kinds of coal mine
Description of drawings
Fig. 1 looks schematic diagram for rushing open formula wind-tunnel door overall structure master.
Fig. 2 is for rushing open formula wind-tunnel door A-A to schematic diagram.
Wherein: 1 bottom girder, 2 wind-tunnel every frames, 3 door-hinges, 4 wind-tunnel doors, 5 pulleys, 6 locating wheels, 7 wire rope, the outstanding bob of 8 gravity, 9 rubber tire framves, 10 rubber wheels, 11 rails, 12 rim.
The specific embodiment.
As shown in drawings, rush open formula wind-tunnel door, its described bottom girder 1 crosswise fixed is seated on the lower frame of described wind-tunnel every frame 2; Between wind-tunnel every frame 2 upper ledges and bottom girder 1 in described wind-tunnel every frame 2 both sides, be coated with a pair of described wind-tunnel door 4 by door-hinge 3, a pair of described wind-tunnel door 4 is an opposite opened; A pair of described pulley 5 is equipped with in the inside and outside both sides on the top of the rim 12 of described wind-tunnel door 4, and the outer rim of a pair of described pulley 5 is near tangent; A pair of described locating wheel 6 is equipped with in the inside and outside both sides of the described rim 12 in a pair of described pulley 5 tops; Described rim 12 is a hollow type, on rim 12 supermedial described wind-tunnel every frames 2 described wire rope 7 is housed fixedly, wire rope 7 is by the wheel ditch of a pair of described pulley 6, and along stretching under rim 12 hollow bulbs, the outstanding bob 8 of described gravity fixedly is equipped with in its lower end; The middle and lower part of described wind-tunnel door 4 is equipped with a pair of described rubber wheel 10 near the inside and outside both sides of described rim 12 by a pair of rubber tire frame 9; The structure of a pair of described wind-tunnel door 4 and configuration be symmetry and identical fully; Pass described bottom girder 1 on the lower frame of described wind-tunnel every frame 2 a pair of rail 11 vertically is housed.
During use, will rush open formula wind-tunnel door earlier and be fixedly installed in the required tunnel, the rail on the wind-tunnel door is connected with rail in the tunnel to get final product.When vehicle during, at first clash into rubber wheel and take advantage of a situation and the wind-tunnel door is pushed open and passed through by this.After vehicle passed through, the wind-tunnel door of unlatching can automatically reset and close under the outstanding effect of weighing down of gravity.No matter vehicle from which direction passes through, and its operating principle all is the same.As long as pushing this door open, the operating personnel of walking just can pass through smoothly.The effect of described location opinion mainly is when guaranteeing the open and close of wind-tunnel door, wire rope is in the wheel ditch of pulley does not all the time dislocate.Because it is not complete closure that the wind-tunnel every is sewed with certain interval, can guarantee that the tunnel, place has small amount of fresh air to pass through, and can not cause distinguished and admirable short circuit again.
