Description
The technical field is as follows:
the utility model relates to a colliery is equipment technical field down, especially relates to an automatic device that shields of spraying for combining adopt working face.
Background art:
combine and adopt the working face because production needs, the staff need frequently pass through full section atomizer, nevertheless because of atomizer covers pedestrian's passageway, often need the manual spray stop valve that closes when personnel pass through atomizer to prevent that the staff from being drenched, treat to open once more after through, the stop valve damages more because of frequent operation, has moreover the staff and forgets the phenomenon of opening the spray stop valve through the back, leads to combining to adopt the face dust serious.
The utility model has the following contents:
an object of the utility model is to provide an automatic device that shields of spraying for combining adopt working face.
The content of the utility model is as follows: the automatic spraying shielding device for the fully mechanized coal mining face comprises a spraying device arranged at the top of the fully mechanized coal mining face, wherein an installation shaft is horizontally arranged under the spraying device, two ends of the installation shaft are fixedly connected with a vertically arranged hanging rod, the top end of the hanging rod is fixedly connected with the top of the fully mechanized coal mining face, two sides of the installation shaft are respectively hinged with a shielding plate, the surface of the shielding plate is parallel to the axis of the installation shaft, a sliding groove is formed in the bottom end of the shielding plate upwards, a sliding plate is connected in the sliding groove in a sliding manner, sliding columns are horizontally and fixedly arranged on two sides of the sliding plate, through grooves are formed in two sides of the shielding plate, the through grooves are communicated with the sliding grooves, the sliding columns are slidably connected with the through grooves, the bottom end of the sliding plate is hinged with a piston rod of an air cylinder, and the air cylinder is fixedly arranged on the inner wall of the fully mechanized coal mining face, the air cylinder is provided with an electromagnetic valve, the electromagnetic valve is electrically connected with the PLC, the PLC is electrically connected with the microwave induction switch, the microwave induction switch is arranged on the connecting rod, and the top end of the connecting rod is fixedly arranged at the top of the fully mechanized coal mining face.
The utility model has the advantages that: the utility model discloses simple structure, the shielding plate that can open and merge is installed in atomizer's below to match intelligent microwave inductive switch, PLC control system and cylinder, when the staff passes through, the shielding plate opens and prevents that the staff from being drenched, and when the staff left, the shielding plate was closed, and atomizer carries out normal spray dust removal work, realizes automaticly, is worth using widely on a large scale.
Description of the drawings:
FIG. 1 is a main body diagram of the present invention;
FIG. 2 is a left body diagram of the present invention;
FIG. 3 is a top view of the present invention;
FIG. 4 is a perspective view of the baffle plate and the slide plate of the present invention;
fig. 5 is a control block diagram of the present invention;
in the figure, a fully mechanized mining face 1, a spraying device 2, a mounting shaft 3, a hanger rod 4, a baffle plate 5, a sliding plate 6, a sliding column 7, a through groove 8, an air cylinder 9, an electromagnetic valve 10, a PLC (programmable logic controller) 11 and a microwave inductive switch 12.
The specific implementation mode is as follows:
as shown in fig. 1 to 5, an automatic spray shielding device for a fully mechanized coal mining face comprises a spraying device 2 installed at the top of a fully mechanized coal mining face 1, an installation shaft 3 is horizontally arranged under the spraying device 2, two ends of the installation shaft 3 are fixedly connected with a vertically arranged hanger rod 4, the top end of the hanger rod 4 is fixedly connected with the top of the fully mechanized coal mining face 1, two sides of the installation shaft 3 are hinged with a shielding plate 5, the surface of the shielding plate 5 is parallel to the axis of the installation shaft 3, a sliding groove is formed in the bottom end of the shielding plate 5 upwards, a sliding plate 6 is connected in the sliding groove in a sliding manner, sliding columns 7 are horizontally and fixedly installed at two sides of the sliding plate 6, through grooves 8 are formed in two sides of the shielding plate 5, the through grooves 8 are communicated with the sliding groove, the sliding columns 7 are connected with the through grooves 8 in a sliding manner, the bottom of slide 6 is articulated with the piston rod of cylinder 9, cylinder 9 fixed mounting combine to adopt on the inner wall of working face 1 install solenoid valve 10 on the cylinder 9, solenoid valve 10 is connected with PLC controller 11 electricity, PLC controller 11 is connected with microwave inductive switch 12 electricity, microwave inductive switch 12 is installed on the connecting rod, the top fixed mounting of connecting rod combine to adopt the top of working face 1.
The working principle is as follows: the during operation, microwave inductive switch 12 senses that it has the staff to pass through in the induction zone (microwave inductive switch is the moving object detector who utilizes the design of Doppler effect principle, it is with the position of non-contact detection object and whether take place to remove, then produce corresponding switch operation), give PLC controller 11 with the sensing signal transmission, PLC controller 11 control solenoid valve 10 action, make the piston rod withdrawal of cylinder 9, thereby make shielding plate 5 open, the staff can follow shielding plate 5 below and pass through, prevent to be drenched, after the staff passes through induction zone completely, cylinder reverse motion, shielding plate 5 is closed.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
