Detailed Description
Referring to fig. 1 to 3, in an embodiment of the present invention, a concrete spraying device for fire-preventing and reinforcing a roadway wall under a coal mine is provided, including:
the movable rail 1 is arranged in a roadway, the movable rail 1 comprises a rail seat 11, a plurality of lifting wheels 12, two symmetrically arranged rollers 13 and a level meter, wherein the lifting wheels 12 are rotatably and liftably arranged in the rail seat 11, the rollers 13 are rotatably arranged in the rail seat 11 and driven by an external motor, a belt 14 is in transmission connection between the two rollers 13, the belt 14 is used for connecting the movable seat 2, the level meter is embedded in the rail seat 11, the position state of the rail seat 11 can be confirmed through the level meter, the rail seat 11 can be made to approach to the horizontal state through the lifting adjustment of the lifting wheels 12, so that the state of the movable rail 1 is guaranteed in a complex roadway environment, good conditions are provided for stable spraying of the subsequent spray head 7, and stable spraying comprises a stable spraying distance;
the movable seat 2 is movably arranged on the movable track 1, specifically, the movable seat 2 can be integrated with a wheel body structure, or a movable driving mechanism such as a telescopic rod is arranged on the movable track 1 to drive the movable seat 2 to move;
an integrated plate 6 provided on the movable base 2;
the air nail gun 9 is fixed on the integrated plate 6 and is used for nailing a nail body into the top wall of the roadway;
the distance meter 10 is fixed on the integrated board 6 and is used for measuring a first distance, wherein the first distance is the distance between the nail body and the distance meter 10; and a spray head 7 fixed on the integrated board 6 for spraying concrete to the roadway top wall, wherein the amount of concrete sprayed by the spray head 7 in unit time is inversely proportional to the first distance, and the inversely proportional change of the amount of concrete sprayed by the spray head 7 in unit time and the first distance means that the amount of concrete sprayed by the spray head 7 in unit time is reduced along with the increase of the distance between the nail body and the range finder 10; the amount of sprayed concrete per unit time of the spray head 7 increases with the decrease in the distance between the nail body and the rangefinder 10.
That is, the hardness of the roof of the roadway can be detected to some extent by driving the nail body into the roof of the roadway by the air nail gun 9, and then the spraying state of the spray head 7 can be adjusted according to the hardness of the roof of the roadway.
Of course, the pin body also has other functions, as will be explained in detail below:
the integrated board 6 is further provided with a fireproof reinforcing component 8, and the fireproof reinforcing component 8 comprises:
a lift cylinder 84;
a first frame 83 fixed to an output end of the lift cylinder 84;
a first press roller 82 fixed to the first frame 83, and a top of the first press roller 82 having a hole structure;
a film cylinder 81 rotatably provided on the integrated plate 6 and providing an intercepting film to an upper surface position of the first press roller 82.
In implementation, the intercepting film can be continuously provided through the film cylinder 81, the intercepting film is positioned on the first press roller 82 and can be pressed on concrete by the first press roller 82, at the moment, an adhesive force exists between the concrete and the intercepting film, although a small part of concrete possibly has poor adhesion and has a tendency of falling off from the top wall of the roadway, most of concrete can be well adhered to the top wall of the roadway, at the moment, an adhesive force exists between the concrete and the intercepting film, and thus, the concrete with poor adhesion and a tendency of falling off from the top wall of the roadway can be intercepted by utilizing the intercepting film;
it should be further explained that, in order to further enhance the adhesion effect of the intercepting film, when the first press roller 82 is about to contact with the nail body, the lifting cylinder 84 is contracted, so that the first press roller 82 avoids the nail body, and then when the hole body structure on the first press roller 82 just corresponds to the nail body, the lifting cylinder 84 is extended, so that the first press roller 82 pushes the intercepting film to approach the nail body and be pierced by the nail body, and further, the positioning fixation of the intercepting film by using the nail body is realized, of course, the positioning is unstable, in order to solve the problem, in this embodiment, one side of the lifting cylinder 84 is further provided with an adaptive member 87, the top of the adaptive member 87 is fixed with a second frame 86, and the second frame 86 is rotatably provided with a second press roller 85.

In this embodiment, the lift cylinder 84 and the adapting member 87 are both fixed on a deflection plate 88, one end of the deflection plate 88 is hinged to the integrated plate 6, and the other end is hinged to a deflection cylinder 89, and the deflection cylinder 89 is hinged to the integrated plate 6.
It will be appreciated that the deflection angle of the deflection plate 88 can be varied by telescopic adjustment of the deflection cylinder 89 such that the deflection angle of the deflection plate 88 is simultaneously micro-deflection adjusted, i.e. the magnitude of this adjustment is small, wherein, for example, the deflection cylinder is elongated, when the deflection cylinder 84 and the adaptation 87 are simultaneously driven upwards, it should be noted that, although the lift cylinder 84 and the adaptation 87 are simultaneously driven upwards, the lift cylinder 84 and the adaptation 87 are not simultaneously driven, in particular, since the lift cylinder 84 and the adaptation 87 are arranged at different positions of the deflection plate 88, the length of the deflection point of the deflection plate 88 is different, the distance of the lift cylinder 84 and the adaptation 87 is different, more particularly, the distance of the adaptation 87 is longer, which enables the second press roller 85 on the adaptation 87 to bend the spike from a deeper depth, and provides a better adhesion to the film.
The adapting member 87 may be an elastic member such as a spring, an elastic pad, etc.
As a preferred embodiment, the intercepting film has a double-layer structure, namely an upper-layer structure and a lower-layer structure, and the upper-layer structure is made of adhesive materials; the lower layer structure is made of fireproof materials.
In a preferred embodiment, the first pressing roller 82 is made of an elastic material, and the second pressing roller 85 is made of a hard metal material.
In this embodiment, move and vertically rotate on the seat 2 and be provided with flexible post 3, flexible end of flexible post 3 is fixed with base 4, adopt the pivot to rotate on the base 4 and be provided with deflection post 5, it is fixed on the deflection post 5 integrated board 6, the length direction of pivot is mutually perpendicular with the length of moving track 1.
It should be noted that the telescopic column 3 can change the spraying distance of the spray head 7 after telescopic adjustment, and the telescopic column 3 is rotatable, so that the deflection direction of the deflection column 5 can be changed by rotation, thereby realizing different spraying paths.
More specifically, the first spraying path is: in general, when the movable rail 1 is arranged, the length direction of the movable rail 1 is parallel to the length direction of the roadway, the spray head 7 realizes spraying in the process that the movable seat 2 moves along the movable rail 1, and then the movable rail 1 is regulated along the width direction of the roadway, so that the gradual spraying of the top wall of the roadway is realized.
Of course, other spraying paths exist, and the second spraying path is: in the state of fig. 1, the telescopic column 3 rotates 90 degrees, when laying the movable track 1, the length direction of the movable track 1 is parallel to the length direction of the roadway, the movable track 1 is positioned in the middle of the roadway, the movable seat 2 is moved along the movable track 1, the spray coating is realized by the spray head 7, the movable seat 2 is intermittently moved, the movable seat 2 is kept static after being moved to a certain position, at the moment, the deflection column 5 deflects, so that the spray head 7 is driven to spray gradually along the top wall of the roadway, and in the process, the interception film is not laid any more.
