Description
[technical field]
The utility model relates to the safety door of mine well head, relates in particular to a kind of electrically operated safety door.
[background technology]
The main shaft well head of former mine uses pneumatic safety door, and major defect is that impact force is big, causes kinematic link, safety door distortion, and maintenance capacity is big.After digging unit stopped production, pressure fan still need start, and energy consumption is big.What former blind main shaft used then is the safety door that hydraulic jack drives, and uses a Hydraulic Station, has the Hydraulic Station seepage, undesirable elements such as contaminated environment.And all there is the secondary transfer problem of the energy in above two kinds of type of drive.
[summary of the invention]
The technical problems to be solved in the utility model provides a kind of electrically operated safety door that uses motor direct-drive to open.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of electrically operated safety door that is applied to the mine well head comprises motor, reducer and shaft coupling, also comprises main vertical shaft, driven vertical shaft, connecting rod, main crank, from crank, safe door leaf and travel switch; The power output shaft of motor is connected with main vertical shaft by reducer, shaft coupling, main vertical shaft is equipped with main crank, main crank is by being connected from crank of being equipped with on connecting rod and the driven vertical shaft, when motor-driven master's vertical shaft rotates by main crank, connecting rod with drive driven vertical shaft from crank and rotate, main vertical shaft is connected with the safe door leaf of a fan, and driven vertical shaft is fanned safe door leaf with another and is connected; At crank maximum rotation angle place and minimum rotation angle place a travel switch is installed respectively.
As preferably, described main vertical shaft is equipped with bearing, and main vertical shaft is connected with bearing support by bearing; Described driven vertical shaft is equipped with bearing, and driven vertical shaft is connected with bearing support by bearing.
The beneficial effects of the utility model are, adopt the switch of motor direct-drive safety door, simple for structure, easy for installation, impact force is little, is difficult for causing the distortion of kinematic link and safety door, maintenance load is little, because the volume of motor and speed reducer is less and connect as one with main shaft, take up room hardly, avoided the shortcoming of former pneumatic or hydraulic driving mode simultaneously.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model embodiment electrically operated safety door structural representation (safety door closed condition).
Among the figure, 1-motor, 2-reductor, 3-shaft coupling, 4-main crank, 5-travel switch, the 6-bearing support, 7-master's vertical shaft, 8-bearing support, 9-bearing support, 10-travel switch, 11-connecting rod, 12-connecting rod, 13-safety door leaf, 14-safety door leaf, 15-be from crank, the driven vertical shaft of 16-.
[specific embodiment]
A kind of electrically operated safety door that is applied to the mine well head comprises motor 1, reducer 2 and shaft coupling 3, main vertical shaft 7, driven vertical shaft 16, two connecting rods, main crank 4, from crank 15, the two safe door leaf of fan and two travel switches.
In Fig. 1, motor 1 is connected with main vertical shaft 7 by reducer 2, shaft coupling 3, on the main vertical shaft 7 main crank 4 is housed, main crank 4 is by being connected from crank 15 of being equipped with on connecting rod 11 and connecting rod 12 and the driven vertical shaft 16, motor 1 drives and passes through main crank 4, connecting rod 11, connecting rod 12 when main vertical shaft 7 rotates and drive driven vertical shaft 16 from crank 15 to rotate, the safe door leaf 13 of a fan fixedly is equipped with in the bottom of main vertical shaft 7, and the bottom of driven vertical shaft 16 fixedly is equipped with another and is fanned safe door leaf 14; Travel switch 5 is contained in main crank 4 maximum rotation angle places (the opening angle maximum of safe door leaf at this moment), and travel switch 10 is contained in the minimum rotation angle place (the opening angle minimum of safe door leaf at this moment) of main crank 4.
3 bearings are housed on the main vertical shaft 7, and 3 bearings of main vertical shaft 7 are contained in three positions, upper, middle and lower of doorframe respectively by 3 bearing supports 6, bearing support 8 and bearing support 9; Equally, 3 bearings are housed also on the driven vertical shaft 16,3 bearings on the driven vertical shaft 16 are contained in three positions, upper, middle and lower of another side doorframe respectively by 3 bearing supports.
The power of used motor is 0.75KW, and used reducer is vertical cycloidal planetary gear speed reducer, and its model specification is BLEY1812-17x11-0.75.
Operating principle:
1) open the door: the signalman presses door open button, motor 1 work, main vertical shaft 7 rotates (two push rods one push away one and draw) synchronously together with driven vertical shaft 16, safe door leaf 13 and safe door leaf 14 are opened, when turning to the position of maximum rotation angle, touches main crank 4 travel switch 5, safe door leaf 13 and safe door leaf 14 are opened and are put in place, and motor 1 quits work automatically.
2) close the door: the signalman presses door close button, motor 1 reverse operation, main vertical shaft 7 rotates (two push rods one push away one and draw) synchronously together with driven vertical shaft 16, safe door leaf 13 and safe door leaf 14 are opened, main crank 4 touches another travel switch 10 when turning to the position of minimum rotation angle, safe door leaf 13 and safe door leaf 14 door-closing in-places, motor 1 quits work automatically.
Present embodiment utilizes motor direct-drive switch safety door, utilizes the opening and closing angle of travel switch control door leaf, and is easy to operate; Two push rods one push away one and draw, and vertical shaft only produces driving torque, do not have radially moment existence, eliminate diastrophic possibility.It is simple for structure, and is easy for installation, and impact force is little, be difficult for causing the distortion of kinematic link, safety door, maintenance capacity is little, because the volume of motor and speed reducer is less and connect as one with main shaft, take up room the shortcoming of having avoided former pneumatic, hydraulic way to drive simultaneously hardly.
