Detailed Description
The following describes the length warning system for inserting a supporting screw rod of a bent frame in detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent in conjunction with the following description. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.
As shown in fig. 1, an adjusting nut 4 is arranged on a screw rod 2, a support screw rod 2 below the adjusting nut 4 is inserted into a bent frame vertical pipe 5 to form a screw rod insertion section 3, the adjusting nut 2 is placed at the top of the bent frame vertical pipe 5, a bent frame support 1 is positioned at the top of the support screw rod 2, the position of the adjusting nut 4 on the support screw rod 2 can be adjusted by rotating the adjusting nut 4, the length of the support screw rod 2 inserted into the bent frame vertical pipe 5 is adjusted, and therefore the height of the bent frame support 1 is adjusted. Preferably, the adjusting nut 4 is provided with an adjusting handle, and the adjusting nut is rotated on the screw rod through the adjusting handle.
Set up ultrasonic sensor 6 and alarm 7 on the framed bent standpipe 5 outer wall, ultrasonic sensor 6's ultrasonic wave perpendicular to framed bent standpipe 5, ultrasonic wave to 5 orificial vertical distance H more than or equal to of framed bent standpipe 5 top insert minimum allowable length H. The ultrasonic sensor 6 carries out object identification through ultrasonic waves, and transmits an identification result to the controller 8 through the data communication line 9, the controller 8 judges whether the ultrasonic waves detect the bracing lead screw, when the ultrasonic waves detect the bracing lead screw, the controller 8 controls the alarm 7 to send out warning information, and the warning information can be multi-light conversion or sound alarm. As shown in fig. 1, the controller 8 is connected to the ultrasonic sensor 6 via a data communication line 9, and the controller 8 is wirelessly connected to the alarm 7 via a network 10.
Before the installation, can mark out warning line 11 on bent standpipe 5, the distance of 11 distance bent standpipe tops of warning line needs to satisfy the requirement, aligns warning line 11 position with ultrasonic sensor 6 and installs on bent standpipe 5. Then, the controller 8 and the alarm 7 are installed, and the controller 8 is connected with the ultrasonic sensor 6 and the alarm 7. The system can be used for detecting whether the supporting screw rod 2 can meet the length requirement, and the principle is as follows: insert the framed bent standpipe with bracing lead screw bottom, through rotatory adjusting nut, the bracing lead screw length that inserts in the framed bent standpipe grow gradually, when bracing lead screw bottom reached warning line department, ultrasonic sensor detected the bracing lead screw, the controller judged that the bracing lead screw has reached the length requirement, the controller sends alarm command to the alarm, the audible and visual warning is sent out to the alarm, operating personnel receives the audible and visual warning after, stop rotatory adjusting nut, can judge that this bracing lead screw satisfies the length requirement. If the adjusting nut rotates to the thread of the top thread of the support screw rod all the time, the audible and visual alarm still does not send out warning information, and the support screw rod does not meet the length requirement.
The system can also be used for detecting whether the length of the lead screw 2 in the use state meets the requirement or not, and the principle is as follows: after the initial installation is finished, the bent frame support 1 is installed, then the adjusting nut 4 is rotated, and the bent frame support 1 is lifted upwards until the bent frame support 1 is tightly propped against the top structure; and then checking whether the alarm 7 sends out warning information or not, if the warning information is continuously sent out, indicating that the ultrasonic sensor can always monitor the supporting lead screw, indicating that the length of the supporting lead screw meets the requirement, and if the alarm 7 does not send out the warning information any more, indicating that the ultrasonic sensor cannot monitor the supporting lead screw, indicating that the length of the supporting lead screw 2 is not matched with that of the bent vertical pipe 5, and needing to replace the supporting lead screw or the bent vertical pipe.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
