Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.
As shown in fig. 1 to 4, the utility model provides an air door anti-collision protection device, which is arranged on an air door in a roadway, a roadway wall and a monorail crane 16, and is used for controlling the monorail crane 16 to realize emergency braking when the air door is not completely opened, so as to prevent the monorail crane 16 from colliding with the air door.
The air door anti-collision protection device comprises a control box 1, a first distance sensor 2, a second distance sensor 3, a third distance sensor 4, a fourth distance sensor 5, a first travel switch 6 and a second travel switch 7.
The control box 1 is arranged on the side wall 8 of the roadway, a storage battery, a controller and a wireless signal transceiver are arranged in the control box 1, and the storage battery is connected with the controller and the wireless signal transceiver and used for supplying power to the controller and the wireless signal transceiver.
The first distance sensor 2 and the second distance sensor 3 are respectively arranged on the roadway top wall 9 at the two sides of the air door and at a distance of ten meters away from the air door; third distance sensor 4, fourth distance sensor 5 set up respectively on the tunnel roof 9 of air door both sides, the distance between third distance sensor 4, fourth distance sensor 5 and air door opening 10 slightly is greater than the width of single fan air door.
The first distance sensor 2, the second distance sensor 3, the third distance sensor 4 and the fourth distance sensor 5 are electrically connected with the controller through the wireless signal transceiver.
The second travel switch 7 is arranged on the inner wall of the right side of the air door opening 10, and a contact of the second travel switch 7 vertically faces the outside of the right side wall. When the right air door 12 is in a fully opened state, the end face of the right air door 12 is in contact with the contact of the second travel switch 7, and the second travel switch 7 is in a closed state; when the right side air door 12 is not in the fully opened state, the end face of the right side air door 12 cannot be in contact with the contact of the second travel switch 7, and the second travel switch 7 is in the opened state.
The first travel switch 6 and the second travel switch 7 are electrically connected with the controller through the wireless signal transceiver.
And the outer walls of the two sides of the air door wall body 13 are provided with a voice alarm device 14 and a warning lamp alarm device 15, and the voice alarm device 14 and the warning lamp alarm device 15 are arranged at the upper end of the air door opening 10 and are electrically connected with the controller through a wireless signal transceiver.
The controller is electrically connected with a brake system control mechanism of the monorail crane 16 through a wireless signal transceiver.
The working principle of the utility model is as follows:
when the monorail crane 16 passes through the air door from right to left, the monorail crane 16 firstly passes through the first distance sensor 2, and when the first distance sensor 2 detects that the distance between the monorail crane 16 and the monorail crane is less than the set distance, the monorail crane 16 starts to pass through. At this time, if any one of the first travel switch 6 and the second travel switch 7 is in an open state, it is indicated that the air door is not in a completely open state, so that the monorail crane 16 runs a risk of colliding with the air door when passing through the air door, and when the controller receives a signal that the travel switch is not closed through the wireless signal transceiver, the controller controls the voice alarm device 14 to send out an alarm voice of 'air door in front, slow down and go' through the wireless signal transceiver, and simultaneously controls the alarm lamp alarm device 15 to send out a flashing red light to remind the monorail crane 16 of the driver of slow down and go.
When the monorail crane 16 continues to run to the third distance sensor 4, if the controller receives a signal that the travel switch is not closed through the signal transceiver, the air door is not opened or is completely opened, the controller controls the braking mechanism of the monorail crane to brake emergently through the signal transceiver, and the monorail crane 16 is prevented from colliding with the air door; at this time, if the controller receives a signal that the first travel switch 6 and the second travel switch 7 are both in the closed state through the signal transceiver, it indicates that both the air doors are completely opened, the controller cannot control the monorail crane 16 to adopt emergency braking, and the monorail crane normally passes through the air doors.
The monorail crane passes through the fourth distance sensor 5 after passing through the air door, the fourth distance sensor 5 detects a signal passed by the monorail crane 16 and transmits the signal to the controller through the wireless signal transceiver, and when the third distance sensor 4 and the fourth distance sensor 5 cannot detect the signal passed by the monorail crane 16, the monorail crane 16 completely passes through the air door.
If the air door is closed suddenly from a fully opened state in the process that the monorail crane 16 passes through the air door, the controller receives a signal for opening the travel switch, and the controller controls the monorail crane to adopt emergency braking in time through the wireless signal transceiver, so that the monorail crane in operation is prevented from colliding with the air door, and the accident is prevented from being enlarged.
When the fourth distance sensor 5 detects that the monorail crane 16 completely passes through, signals are transmitted to the controller, and the controller controls the voice alarm device 14 and the warning lamp alarm device 15 to stop working through the wireless signal transceiver.
When the monorail crane 16 passes through the damper from left to right, the working principle is similar, except that the first distance sensor 2 is changed into the second distance sensor 3, and the other principles are the same.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
