[0002] The beam lifting machine is a gantry crane specially designed for bridge construction. The beam lifting machine is mainly composed of assembled main beams, outriggers, overhead cranes, etc. The components are connected by pins and high-strength bolts, which are easy to disassemble and transport. Compared with ordinary gantry cranes, the beam lifting machine is easy to install, fast, economical and practical.

[0003] At present, the beam lifting machine works outdoors, and it is difficult for on-site staff to discover abnormal high temperature faults in the first time, which can easily lead to the beam lifting machine's shutdown due to faults. After the shutdown, on-site staff usually use an overall survey method to check the beam lifting machine, find out the abnormality, and then carry out repairs. Obviously, this investigation method is time-consuming, labor-intensive, and inefficient. On the other hand, temporary repairs are difficult to completely solve the fault, and similar faults may be encountered in subsequent work. Therefore, in the prior art, only the on-site staff know about a specific fault, and others cannot know. In other words, subsequent staff cannot understand the historical maintenance information of the beam lifting machine. When encountering the same fault, they need to conduct a comprehensive survey again, which is time-consuming and labor-intensive. Utility Model Content

[0007] The abnormal temperature judgment module is used to judge the temperature detected by the temperature detection module, and when it exceeds the threshold, it sends an abnormal signal to the abnormal temperature alarm module and the information sending module;

[0008] The abnormal temperature alarm module is used to receive abnormal signals and issue an alarm;

[0009] The information sending module is used to receive abnormal signals and send them to the platform;

[0036] Furthermore, if Figure 1 As shown, the monitoring subsystem also includes a timing module; the timing module is connected to the abnormal temperature alarm module, which is used to record the duration of the alarm and send it to the brake. The brake can make a judgment based on the alarm duration, and when the alarm duration exceeds the preset duration, it will force the lifting beam machine to stop working, so as to prevent the abnormal high temperature fault from expanding and causing more serious losses.

[0037] Further, if Figure 2 As shown, the monitoring system also includes an RFID metal chip and a handheld terminal;

In actual work, staff can patrol and inspect regularly, scan the RFID metal chip on any beam lifting machine through the handheld terminal, first obtain the equipment information, and then retrieve other information of the beam lifting machine through the platform based on the equipment information. In other cases, when it is inconvenient for staff to scan on site, they can provide a way to input equipment information to obtain other information of the corresponding beam lifting machine. Depending on the degree of confidentiality, the number of items that need to be entered for equipment information can be set, for example, only entering the number can be retrieved, or the name, model and number of the equipment need to be correctly entered to successfully extract other information. The "other information" here includes the abnormal signals mentioned in the previous text, as well as the maintenance information and image information in the following text.

[0040] Furthermore, the handheld terminal is also provided with a maintenance information sending module for sending maintenance information to the platform, and the information retrieving module is also used for retrieving maintenance information.

[0041] Furthermore, the handheld terminal is also provided with a security login management module for verifying the login personnel information.

[0043] Preferably, there are multiple photographing modules, and they are arranged in pairs with the temperature detection modules at the same location.

[0044] Example 2

[0045] This embodiment provides a beam lifting machine temperature information monitoring system.

[0046] like Figure 3As shown, the temperature information monitoring system of the lifting beam machine includes: a temperature detection module 1, which is used to detect the internal temperature of the equipment; an abnormal temperature judgment module 2, which is connected to the output end of the temperature detection module 1, and is used to judge whether the temperature is abnormal. When the temperature exceeds the threshold, an abnormal signal is output; a shooting module 3, which is connected to the output end of the abnormal temperature judgment module 2, and is used to receive the abnormal signal output by the abnormal temperature judgment module 2. When the shooting module 3 receives the abnormal signal, it shoots the internal image information of the equipment; an image information sending module, which is connected to the output end of the shooting module 3, and is used to receive the internal image information of the equipment sent by the shooting module 3, and sends the image to the platform; a handheld terminal, which is used to read the device information stored in the RFID tag on the device, and the handheld terminal and the platform interact with each other, and the interaction method uses WIFI or 4G. The equipment information includes the equipment name, equipment model and equipment number, as well as the previous maintenance information.

[0047] The temperature detection module 1 includes a plurality of temperature sensors, which are respectively located at the bearing position, the reduction gearbox position, the brake position and the motor position of the device, and are used to detect the temperature of the corresponding positions. The shooting module 3 includes a plurality of cameras, which are respectively located at the bearing position, the reduction gearbox position, the brake position and the motor position of the device, and are used to shoot images of the corresponding positions.

[0048] The handheld terminal includes an information retrieval module for retrieving image information stored on the platform. The handheld terminal also includes a maintenance information sending module for sending maintenance information to the platform, and the maintenance information is entered by the operator. After the operator retrieves the image information through the information retrieval module on the handheld terminal, he can view the image information and make a preliminary judgment on the problem. He can perform maintenance based on the judgment result, which greatly saves time and manpower and improves efficiency.

[0049] The handheld terminal also includes a security login management module for verifying the information of the login person, which includes driver information, position, relevant certificate photos, etc., to improve the security of the handheld terminal when in use.

[0050] The monitoring system further includes an abnormal temperature alarm module 4, which is connected to the output end of the abnormal information judgment module. When the abnormal temperature alarm module 4 receives an abnormal signal, the abnormal temperature alarm module 4 is activated. The abnormal temperature alarm module 4 can be an alarm installed on the equipment to remind the operator that the equipment has an abnormal condition.

[0051] The monitoring system also includes a timing module 5, which is connected to the output end of the abnormal temperature alarm module 4. When the abnormal temperature alarm module 4 is activated, the timing module 5 starts timing. When the timing exceeds the threshold, the device is forced to shut down. The abnormal temperature alarm module 4 includes automatic shutdown and manual shutdown.

[0052] When the abnormal temperature alarm module 4 receives an abnormal signal and starts, the timing module 5 starts timing and records the duration of the alarm, that is, the duration of the device abnormality. If the alarm continues to alarm and exceeds the maximum alarm duration, the device is forced to shut down. This situation may be that an abnormality occurs when the device is turned on but not working, and the operator is not next to the device. When the device is forced to shut down, the abnormal temperature alarm module 4 automatically powers off; or the operator manually turns off the abnormal temperature alarm module 4 and cancels the alarm. Generally, the operator knows that the temperature inside the device is too high.

[0053] like Figure 4 , Figure 5 As shown, the abnormal temperature judgment module 2 includes a comparator T, the shooting module 3 includes a normally open switch KA2-1, the abnormal alarm module includes a normally open switch KA3-1 and an alarm, and the timing module 5 includes a power-on delay relay KT1.

[0054] One end of the normally closed switch KA1-1 is electrically connected to the power supply VCC, the other end of the normally closed switch KA1-1 is electrically connected to the temperature sensor P, the other end of the temperature sensor P is electrically connected to the positive input end of the comparator T, the output end of the comparator T is electrically connected to the base of the transistor Q, the collector of the transistor Q is electrically connected to one end of the resistor R1, the other end of the resistor R1 is connected to the power supply VCC, the emitter of the transistor Q is electrically connected to one end of the electromagnetic coil KA2, the other end of the electromagnetic coil KA2 is electrically connected to one end of the electromagnetic coil KA3, and the other end of the electromagnetic coil KA3 is grounded.

[0055] One end of the normally open switch KA2-1 is electrically connected to the power supply VCC, the other end of the normally open switch KA2-1 is electrically connected to the input end of the power supply of the shooting module 3, the output end of the power supply of the shooting module 3 is electrically connected to the resistor R2, and the other end of the resistor R2 is grounded.

[0056] Among them, the shooting module includes a camera and a control switch. When the normally open switch KA2-1 is turned on, the power supply of the shooting module 3 is energized, and the control switch starts to control the camera action to shoot the inside of the device.

[0057] One end of the normally open switch KA3-1 is connected in parallel between the normally open switch KA2-1 and the power supply VCC, the other end of the normally open switch KA3-1 is electrically connected to one end of the alarm, the other end of the alarm is electrically connected to the power-on delay relay KT1, and the other end of the delay relay KT1 is electrically connected to the ground end of the resistor R2.

[0058] One end of the normally open switch KT1-1 is connected in parallel between the normally open switch KA3-1 and the power supply VCC, the other end of the normally open switch KT1-1 is connected to one end of the electromagnetic coil KA1, and the other end of the electromagnetic coil KA1 is electrically connected to the ground end of the resistor R2.

[0059] When the device is working, the normally closed switch KA1-1 is closed, the temperature sensor P detects the temperature, and sends the detected temperature value to the comparator T. The comparator compares the temperature value inside the device with the preset value. When it is determined that the temperature value inside the device exceeds the preset value, it outputs an abnormal signal, the transistor Q is turned on, the electromagnetic coils KA2 and KA3 are turned on, and the normally open switch KA2-1 is turned on. The camera module is powered on and starts to shoot the internal situation of the device and upload it to the platform. The normally open switch KA3-1 is turned on, the alarm is powered on, and the power-on delay relay KT1 is turned on. When the delay reaches the preset time, the normally open switch KT1-1 is turned on, the electromagnetic coil KA1 is powered on, and the normally closed switch KA1-1 is disconnected, and the device stops.

[0060] In a temperature information monitoring system for a beam lifting machine provided by the present embodiment, the temperature detection module can monitor the temperature inside the equipment in real time, transmit the temperature inside the equipment to the abnormal temperature judgment module, judge the temperature inside the equipment through abnormal temperature judgment, and if the temperature inside the equipment exceeds the threshold, output an abnormal signal to the shooting module, the shooting module responds to the abnormal temperature judgment module, and then shoots the image inside the equipment, sends the image information to the platform through the image information sending module, the platform stores the image information, the operator scans the tag on the RFID through the handheld terminal to obtain the information of the equipment, the operator operates the handheld terminal, and retrieves the image information on the platform through the information retrieval module of the handheld terminal, so that the operator can intuitively find the situation inside the equipment, and can quickly find out the problem without checking the problem one by one, thereby improving the maintenance efficiency, and the image information is stored on the platform, which can also facilitate other people to retrieve the information when using the equipment; at the same time, after the operator solves the abnormal problem of the equipment, the solution is entered into the handheld terminal, and the purpose of mutual information retrieval can be achieved through the interaction between the handheld terminal and the platform.

[0061] It can be seen that the technical solutions provided by the above two embodiments can quickly discover the high temperature fault of the beam lifting machine, and issue an alarm to remind the staff in the first time, and can also store abnormal signals. Furthermore, the historical abnormal signals can effectively shorten the troubleshooting time, reduce time and manpower consumption, and reduce maintenance costs.
