Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific implementation mode
In order to make the purpose of this utility model and advantage be more clearly understood, with reference to embodiments to the utility model into
Row is further described.It should be appreciated that specific embodiment described herein is only used to explain the utility model, and do not have to
In restriction the utility model.
As shown in Figure 1, the utility model embodiment provides a kind of bridge dynamic horizontal stable monitoring device, including two or three
Angle support 1, two A-frames, 1 upper horizontal are provided with a rack beam 2, can by a montant on the rack beam 2
Rotation has a swivel becket 4, and 4 lower end of swivel becket rigid connection, one plummet 3, montant upper end both sides are equipped with one for installing
Right side emits the mounting post 5 of infrared probe 6 and left side transmitting infrared probe 7, the right side transmitting infrared probe 6, a left side
Side transmitting infrared probe 7 has sensor 8, the sensor 8 to be electrically connected with an alarm indication by data line electrical connection
Device 9；5 left and right sides of the mounting post is symmetrically installed with one group of obstacle receiver 10, the obstacle receiver by receiving holder
10 are arranged to F shapes；The neutral gear portion of the right side transmitting infrared probe 6, left side transmitting infrared probe 7 and obstacle receiver
The center divided is in same horizontal line.The reception pedestal lower end is equipped with plummet.The rack beam 2 and the peace
Fill the setting of 5 right angle setting of column.5 both ends open of the mounting post, the right side transmitting infrared probe 6, left side emit infrared ray
Probe 7 is vertically placed in the both ends open of mounting post.The montant lower end is connected across rack beam 2 with the swivel becket 4, on
End is affixed with the bottom surface of the mounting post 5, and the rack beam 2 and the montant are that horizontal direction is rotatable, vertical square
To not slidable connection.
This specific implementation in use, set up holder 1 first, and two holders 1 of guarantee are in same level height, in crossbeam 2
On be inserted in the montant 3 that ring is freely rotated in band, then by crossbeam placement be fixed on holder 1,3 lower end of montant rigid connection can band
Silk mouth is rotatablely connected plummet 4, and 3 upper end of montant can directly fix non-removable card slot 5, left and right infrared ray is embedded in card slot 5
Probe 6,7, jiggles montant 3 and plummet 4, sees that 6,7 montant 3 with 4 card slot 5 of plummet and embedded infrared probe is whole
Whether body can be freely rotated, to ensure that entire montant 3 is in vertical state under 4 gravity of plummet, thus perpendicularly to vertical bar 3
Card slot 5 and infrared probe 6,7 be in horizontality, the infrared ray launched in this way is in horizontality always；In obstacle
Lateral stiffness connects two cross bars 10 on object receiver montant 3, and ensures that barrier cross bar 10 is horizontal, between barrier cross bar 10
The vertical spacing for keeping 3cm to 8cm；Entire emitter and the barrier acceptor device on both sides keep the spacing of 1m to 2m；
The horizontal absolute altitude that entire transmitting infrared facility and obstacle device are adjusted before beam body does not rotate, keeps the level launched red
The neutral gear centre position part between barrier cross bar is just passed through in outside line.Then swivel bridges start rotator construction, if rotation
Bridge both ends horizontal, then obstacle device and transmitting infrared facility relative elevation are constant, the infrared ray launched is always
The neutral gear between obstacle device cross bar is passed through, sensor is not alarmed, and display does not also show alarm explanation；If in rotation
A certain amount of inclination occurs for bridge both ends, and obstacle device just will produce variation with the vertical relative elevation of emitter, horizontal red
Outside line and the vertical distance of barrier cross bar one will change, when swivel bridges tilt to it is a certain amount of when, level infrared light will touch
It runs into barrier cross bar and alarms, display will show specific infrared alarming number, to judge bridge both ends
Tilt quantity, thus play the role of the dynamic stability monitoring and warning in swivel bridges rotation process.
The utility model horizontal stable grading forewarning system monitoring device, when beam body is all horizontal in entire swivel bridges rotation process
When, emitter, obstacle acceptor device is all in the same horizontal plane, the neutral gear of the infrared ray launched and obstacle receiver
Part is also in same horizontal line, and such infrared sensor does not touch barrier, would not alarm, illustrate in rotation
Swivel bridges be it is horizontal, stablize there is no problem, when in rotation swivel bridges both ends tilt when, barrier recipient can be with transmitting
Device forms height difference, and horizontal infrared ray will touch the cross bar of obstacle receiver neutral gear or more, by the infrared ray sensing stopped
Device will alarm, and illustrate that the swivel bridges in rotation are no longer horizontal, dynamic stability declines.
