[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3As shown, this embodiment provides a safety monitoring device for a suspended concrete bridge-building machine, comprising a plurality of gravity conversion mechanisms 1 fixedly connected to a plurality of load-bearing tension rods 4 of the suspended concrete bridge-building machine 6, a pressure sensor 2 arranged below the gravity conversion mechanism 1, a terminal for receiving monitoring data of each of the pressure sensors 2, and an alarm mechanism connected to the terminal, wherein the gravity conversion mechanism 1 can convert the gravity borne by the load-bearing tension rods 4 into a pressure applied to the pressure sensor 2, the top of the pressure sensor 2 contacts the gravity conversion mechanism 1 and is used to monitor the pressure generated by the gravity conversion mechanism 1 thereon, and the bottom of the pressure sensor 2 contacts the load-bearing beam 4 of the suspended concrete bridge-building machine;

[0020] After the installation is completed, since the position of the load-bearing beam 4 is fixed, the position of the pressure sensor 2 remains unchanged under the reaction force of the load-bearing beam 4. After the load-bearing tension rod 4 is subjected to vertical downward tension, pressure is applied to the pressure sensor 2 through the gravity conversion mechanism 1. The pressure sensor 2 performs real-time data monitoring, and the measured data is transmitted to the terminal through wired or wireless transmission. The weight data of each key part is displayed through the terminal, which is convenient for managers at all levels to monitor on-site operations, and can intuitively grasp the transport status, achieve transparent supervision, and when the pressure data is abnormal, an alarm can be issued through the alarm mechanism;

[0021] In order to facilitate the pressure sensor 2 to accurately detect pressure data, in a further embodiment, as Figure 3 As shown, the gravity conversion mechanism 1 includes a pressure-applying assembly 110 detachably connected to the load-bearing tension rod, and a first pad 101 movably sleeved on the load-bearing tension rod. The pressure sensor 2 is arranged below the first pad 101 and in contact with it. The pressure is applied to the pressure sensor 2 through the first pad 101, which can protect the pressure sensor 2 and provide stable pressure transmission.

[0022] In order to facilitate installation and disassembly, in a further embodiment, the load-bearing tension rod is provided with an external thread, and the pressure assembly 110 includes a pressure nut 111 and a lock nut 112 threadedly connected to the load-bearing tension rod, and the lock nut 112 is arranged on a side of the pressure nut 111 away from the pressure sensor 2;

[0023] By analyzing the operating status of the bridge-building machine, in order to improve the comprehensiveness and accuracy of monitoring, in a further implementation method, Figure 1 , Figure 2 As shown, the weight of the stress rods at various parts of the suspended grouting bridge-building machine 6 that play a major supporting role is monitored in real time, wherein the weighing tension rods include the front suspension rod, the rear suspension rod, the front anchor rod, and the rear anchor rod. During the monitoring process, the stress condition of the entire suspended grouting bridge-building machine can be well characterized, thereby improving the real-time perception capability under the changing working conditions;

A second pad 3 is also provided between the pressure sensor 2 and the load-bearing beam, which can cooperate with the first pad 101 to protect the pressure sensor 2. An aviation plug interface 201 is provided on the side of the pressure sensor 2 for real-time transmission of detected pressure data.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
