[0002] Bridge erecting machine is a kind of heavy machinery and equipment specially used for bridge construction, and is widely used in the construction of highway, railway and urban rail transit infrastructure, etc., and its main function is to safely and quickly install prefabricated bridge components to the designated position.The structure of bridge erecting machine includes machine body, hoisting trolley and multiple supporting legs, wherein the machine body is the main part of the bridge erecting machine, usually made of steel, has high strength and stability, the hoisting trolley is the key part of the bridge erecting machine, used for lifting and moving bridge components, and the supporting leg is an important structure of the bridge erecting machine supporting the machine body during operation, which can be extended or unfolded to maintain the stability of the machine body.Usually, two hoisting trolleys are provided, including front hoisting trolley and rear hoisting trolley, the cooperation of front hoisting trolley and rear hoisting trolley can share the load and reduce the load of single hoisting trolley, so as to improve the operation efficiency and stability.

[0003] When the front hoisting trolley and the rear hoisting trolley are used to hoist the bridge components at the same time, it is necessary to ensure that the moving speed of the front and rear hoisting trolleys in the same direction is consistent, so as to avoid the inclination and deformation of the hoisted bridge components due to the shortening or lengthening of the distance between the front and rear hoisting trolleys.At present, it is found in actual construction that under special circumstances, the wind force received by the front and rear hoisting trolleys is quite different, for example, when small parts are quickly transported under strong wind, the distance between the front and rear hoisting trolleys is small, at this time, when moving with the wind, the rear hoisting trolley receives a larger boost force, which is easy to accelerate forward relative to the front hoisting trolley, or when moving against the wind, the front hoisting trolley receives a larger wind resistance, which is easy to decelerate forward relative to the rear hoisting trolley, so as to ensure that the moving speed of the front and rear hoisting trolleys in the same direction is consistent, which undoubtedly increases the risk of inclination and deformation of the hoisted bridge components.

[0024] The present application will be further described below with reference to the accompanying drawings and embodiments. Figure 1 - the accompanying drawings Figure 4 and embodiments.

[0025] The embodiment discloses a bridge girder erection machine operation automatic monitoring, early warning and control system.

[0026] With reference to Figure 1 and Figure 2 , the bridge girder erection machine operation automatic monitoring, early warning and control system comprises a detection group, a memory, a remote server and a man-machine interaction module, the detection group is used for collecting current wind direction, wind speed and the distance between front and rear two lifting trolleys, the memory is used for receiving wind direction data, wind speed data and distance data, the remote server is used for judging a risk value according to the wind direction data, the wind speed data and the distance data of the memory and for sending an early warning signal, and the man-machine interaction module is used for allowing a worker to control the front and rear two lifting trolleys to start at a reduced speed or to stop starting according to the early warning signal. Specifically, the remote server first judges the included angle between the current wind direction and the arrangement direction of the front and rear two lifting trolleys according to the wind direction data, if the current included angle value is less than an included angle threshold value, it indicates that the current wind direction tends to be parallel to the moving direction of the front and rear two lifting trolleys, and then further judgment is made according to the wind speed data and the distance data, the risk value increases synchronously with the increase of the wind speed or the decrease of the distance, if the current risk value exceeds a risk threshold value, it indicates that the front and rear two lifting trolleys are prone to produce speed difference when moving small pieces at a high speed, thereby increasing the risk of inclination and deformation of the bridge member, at this time, the remote server sends an early warning signal to remind the worker to operate the man-machine interaction module. It should be noted that if the included angle between the current wind direction and the arrangement direction of the front and rear two lifting trolleys is not less than the included angle threshold value, it indicates that the front and rear two lifting trolleys are neither in the downwind condition nor in the upwind condition, at this time, the wind force is not easy to cause difference in the speed of the front and rear two lifting trolleys, thereby there is no need to further judge the risk. In summary, in the remote server, the relationship between the risk value and the wind direction data, the wind speed data and the distance data is: risk value = wind direction coefficient * wind speed coefficient * distance coefficient, wherein the wind direction coefficient is 0 or 1, the wind speed coefficient and the distance coefficient are both located between 0 and 1, the wind speed coefficient increases with the increase of the wind speed data, and the distance coefficient increases with the decrease of the distance data, so that the risk value is located between 0 and 1.

[0027] With reference to Figures 1 to 4, the detection group comprises a wind vane 6, an anemometer and a distance sensor 5, the wind vane 6 and the anemometer are arranged on the machine body 1 of the bridge girder erection machine, the wind vane 6 is used for detecting the current wind direction, and the anemometer is used for detecting the current wind speed; the distance sensor 5 is arranged between the front and rear trolleys, and is used for detecting the distance between the front and rear trolleys. Specifically, the machine body 1 of the bridge girder erection machine is provided with a mounting table 4, the wind vane 6 and the anemometer are arranged on the mounting table 4, and the mounting table 4 is arranged on the side wall of the machine body 1, so as to avoid that the mounting table 4 is located between the gaps between the front and rear trolleys, thereby reducing the influence of the front and rear trolleys on the wind vane 6 and the anemometer. The distance sensor 5 comprises a transmitting end and a reflecting end, and the transmitting end and the reflecting end are arranged on the front trolley 2 and the rear trolley 3 respectively, and in this embodiment, the transmitting end and the reflecting end of the distance sensor 5 are located on the same side wall of the front trolley 2 and the rear trolley 3 respectively.

[0028] With reference to Figures 1 to 4 Further, the mounting table 4 is a movable mounting table 4, the mounting table 4 is kept between the front and rear trolleys by moving, and the wind vane 6 is located beside the sensing path of the distance sensor 5, so as to: when the wind direction is not close to parallel to the arrangement direction of the front and rear trolleys, the included angle between the wind direction and the arrangement direction of the front and rear trolleys is large, and one end of the wind vane 6 will block the sensing path of the distance sensor 5; when the wind direction is close to parallel to the arrangement direction of the front and rear trolleys, the included angle between the wind direction and the arrangement direction of the front and rear trolleys is small, and one end of the wind vane 6 no longer blocks the sensing path of the distance sensor 5. Based on this, the remote server can determine whether the included angle between the current wind direction and the arrangement direction of the front and rear trolleys is less than an included angle threshold value, that is, whether the current wind direction will cause a speed difference between the front and rear trolleys, by judging whether the distance sensor 5 can detect the distance data. Therefore, only the distance sensor 5 and the remote server need to be signal-connected, so as to monitor the wind direction data and the distance data at the same time, thereby achieving the effect of simplifying the system. Moreover, the distance between the rotating shaft of the wind vane 6 and the sensing path can be adjusted at this time, so as to adjust the included angle threshold value, so as to facilitate adjustment according to requirements.

[0029] With reference to Figures 1 to 4 The anemometer is arranged on the wind vane 6, so that the anemometer can swing with the wind vane 6, thereby accurately measuring the wind speed of the current wind direction. In addition, the anemometer is signal-connected with the distance sensor 5, so that the anemometer starts and detects the wind speed only after the distance sensor 5 detects the distance data and determines that the current wind direction will affect the speed difference between the front and rear trolleys, thereby reducing unnecessary detection and reducing the storage pressure of system data.

[0030] With reference to Figures 1 to 4When the detection group detects the wind direction data, the wind force data and the distance data, the two cranes keep static state, so that the installation table 4 also keeps static state, avoiding the interference of the moving installation table 4 to the detection of the wind vane 6. After the risk is detected and judged, the subsequent starting speed of the two cranes or the stop starting is adjusted according to the risk value, so as to reduce the risk of the hoisted bridge member being inclined and deformed.

[0031] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
