Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model one tower crane side-play amount is monitored device to be described in detail:
Fig. 1 is this utility model structural representation, and it includes RF transmitter 1, infrared receiver 2, side-play amount display 3 and alarm 4.
RF transmitter 1 is arranged on the underframe 6 of tower crane, and infrared receiver 2 is arranged on the intersection of horizontal arm support 5 and standard knot, and side-play amount display 3 is arranged on underframe 6, and alarm 4 is connected with side-play amount display 3.
The installation site of RF transmitter 1 and infrared receiver 2 is equipped with, and the installation site of RF transmitter 1 overlaps with the projected position of infrared receiver 2, and infrared ray 7 is transmitted to infrared receiver 2 by RF transmitter 1.
Fig. 2 is the side-play amount display schematic diagram of this utility model, being provided with infrared circle 8 and cordon 9, the cordon 9 on side-play amount display 3 is multiple concentric circular, and it changes along with increasing of the tower crane scope of operation, to improve the grade of tower crane side-play amount monitoring, it is ensured that the safety of tower crane operation；When initially adjusting, the infrared circle 8 on side-play amount display 3 is concentric circular with cordon 9, to monitor the side-play amount of tower crane to greatest extent in all directions.
When the infrared circle 8 on side-play amount display 3 exceedes cordon 9, alarm 4 starts, and sends safety alarm；When infrared ray 7 between RF transmitter 1 and infrared receiver 2 is blocked by an external matter, the infrared circle 8 on side-play amount display 3 disappears, and alarm 4 starts, and sends safety alarm.
Described infrared circle 8 exceedes the disappear chimes of doom of alarm device 4 of the chimes of doom of cordon 9 alarm device 4 and infrared circle 8 and there are differences, occur that deviation and infrared ray are blocked the identification of both of these case improving tower crane side-play amount, improve operator's convenience to the eliminating of fault.
