Referring to fig. 1, in the present embodiment, it is exemplarily illustrated that two trolleys 11 are slidably disposed on a boom 12 of a bridge girder erection machine, and a first stabilizer 1 and a second stabilizer 2 are respectively disposed on one trolley 11. In some embodiments, when the number of the trolley 11 is greater than two, the first stabilizer 1 and the second stabilizer 2 are preferably disposed on two trolleys 11 that are farthest apart. And the first column 13 is arranged at the front end of the arm 12 of the bridge girder erection machine, the second column 14 is arranged in the middle of the arm 12 of the bridge girder erection machine, and the third column 15 is arranged at the rear end of the arm 12 of the bridge girder erection machine.
Before the two hoisting trolleys 11 hoist the precast beam plate, leveling treatment is carried out on the precast beam plate. It can be understood that, because the precast beam slab is located at the finished construction section of the bridge before hoisting, the precast beam slab is convenient for leveling and detecting whether the precast beam slab is kept horizontal before hoisting, and particularly, whether the precast beam slab is kept horizontal can be detected through a total station.
Referring to fig. 3 and 4, after the two trolleys hoist the precast beam slab, the controller 6 obtains the height of the two ends of the precast beam slab, which rises when the two trolleys hoist the precast beam slab, and records the height as H1 and H2. After the two trolleys 11 hoist the precast beam slab, and before the two trolleys 11 move on the horn 12, the first signal transmitting module 3 and the second signal transmitting module 4 respectively transmit a first detection signal and a second detection signal to the plurality of signal detecting modules 5, the signal detecting modules 5 send the first detection signal and the second detection signal to the controller 6 after receiving the first detection signal and the second detection signal again, the controller 6 acquires the two signal detecting modules 5 receiving the strongest signals according to the strength of the signals received by the plurality of signal detecting modules 5, and records the positions of the two signal detecting modules 5 as the position A and the position B respectively.

At this time, the controller 6 can obtain the height position changes of the two end parts of the precast beam slab in the hoisting process according to the height difference between the position A and the position A1 and the height difference between the position B and the position B1, correct H1 and H2 according to the height position changes, and then control the two lifting trolleys 11 to lower the precast beam slab.

The first stabilizer 1 and the second stabilizer 2 are arranged in a staggered manner, so that the situation that the first detection signal and the second detection signal cannot be received by the signal detection modules 5 due to the fact that propagation is blocked is avoided. The housing 7 serves as a carrier for the first signal transmission module 3 and the second signal transmission module 4, so that the first signal transmission module 3 and the second signal transmission module 4 are arranged on the first stabilizer 1 and the second stabilizer 2, respectively.
It can be understood that the first stabilizer 1 and the second stabilizer 2 have a function of damping the first signal transmission module 3 and the second signal transmission module 4 due to the spirally arranged structure thereof and the elastic property thereof. When the trolley 11 is vibrated in the moving process, the vibration can be absorbed and counteracted by the first stabilizer 1 or the second stabilizer 2 in the transferring process to reduce the vibration on the shell 7 at the innermost end of the first stabilizer 1 and the second stabilizer 2, so that the first stabilizer 1 and the second stabilizer 2 can keep the stability when the first signal transmitting module 3 and the second signal transmitting module 4 respectively transmit the first detection signal and the second detection signal, and the position error of the first signal transmitting module 3 and the second signal transmitting module 4 when the signal detecting modules 5 receive the signals due to the vibration is avoided, and further the effect of horizontally mounting the precast beam slab is ensured.
Referring to fig. 5, more specifically, each turn of the first stabilizer 1 and the second stabilizer 2 is triangular in shape when they are spirally arranged.

In the present embodiment, it is exemplarily illustrated that the first stabilizer 1 and the second stabilizer 2 are wound three-dimensionally, rather than being wound in one plane, and the winding directions thereof are both horizontal directions, and in the present embodiment, the tapered tip portions of the first stabilizer 1 and the second stabilizer 2 are both directed toward the first column 13 of the bridge girder erection machine.
It can be understood that the first stabilizer 1 and the second stabilizer 2 extend horizontally when they are spirally arranged, and the transmission path of the vibration can be extended, so as to effectively improve the damping effect of the first stabilizer 1 and the second stabilizer 2 in a limited space.
Referring to fig. 1 and 4, specifically, the first signal transmitting module 3 and the second signal transmitting module 4 respectively transmit the first detection signal and the second detection signal horizontally, the plurality of signal detecting modules 5 are all disposed on a plate body 8, and the plate body 8 is perpendicular to the first detection signal and the second detection signal.
In the present embodiment, it is exemplarily illustrated that a plurality of signal detection modules 5 are arranged on a rectangular plate body 8 in a rectangular array, and two signal detection modules 5 adjacent to each other in the length direction and the width direction of the plate body 8 are abutted against each other so as to determine the change of the receiving positions of the first detection signal and the second detection signal.
It can be understood that the first signal transmitting module 3 and the second signal transmitting module 4 respectively transmit the first detection signal and the second detection signal horizontally, and are perpendicular to the plate body 8, so that the controller 6 can obtain the position of the signal detecting module 5 which receives the first detection signal and the second detection signal with the maximum intensity, and the effect of horizontally installing the precast beam plate can be improved.
Referring to fig. 5 and 6, more specifically, the housing 7 and the innermost ends of the first stabilizer 1 and the second stabilizer 2 are connected by a universal joint 9.
In the present embodiment, it is exemplarily explained that the universal joint 9 is used for adjusting an angle of the housing 7 to adjust angles of the first signal transmitting module 3 and the second signal transmitting module 4 for transmitting the first detection signal and the second detection signal. It can be understood that the angles at which the first signal transmitting module 3 and the second signal transmitting module 4 transmit the first detection signal and the second detection signal may deviate and no longer remain horizontal or may be difficult to maintain vertical to the plate body 8 during use, which may be adjusted by the universal joint 9.
Specifically, the first detection signal and the second detection signal are two electromagnetic wave signals having different frequencies.
In the present embodiment, it is exemplarily explained that the electromagnetic wave is an electromagnetic field that propagates in the form of a wave, by setting the first detection signal and the second detection signal as two types of electromagnetic wave signals different in frequency, and configuring the several signal detection modules 5 to: the electromagnetic wave under different frequencies can be received, the purpose that the first signal transmitting module 3 and the second signal transmitting module 4 can simultaneously transmit the first detection signal and the second detection signal can be achieved, interference between the first detection signal and the second detection signal can be avoided, and the effect of horizontally installing the precast beam plate can be guaranteed.
Referring to fig. 5 and 6, specifically, a windshield 10 is disposed outside each of the first stabilizer 1 and the second stabilizer 2, and the windshield 10 is open at least on a side where the extending direction of the first detection signal and the second detection signal is located.
In the present embodiment, it is exemplarily explained that the windshield 10 is provided as a rectangular parallelepiped case 7 which is provided to cover the first stabilizer 1 and the second stabilizer 2, and one end of the windshield 10 is opened and the other end is closed. One end of the opening of the windshield 10 is an end close to the first column 13 of the bridge erecting machine, so that the first signal emitting module 3 and the second signal emitting module 4 emit the first detection signal and the second detection signal, respectively.
It can be understood that the windshield 10 forms a barrier for the first stabilizer 1 and the second stabilizer 2, and can reduce the interference caused by strong wind to the first stabilizer 1 and the second stabilizer 2, so that the first stabilizer 1 and the second stabilizer 2 stably play a role of shock absorption.
The implementation principle of the first stabilizer 1 and the second stabilizer 2 in the embodiment of the present application is as follows:
before the two hoisting trolleys 11 hoist the precast beam plate, leveling treatment is carried out on the precast beam plate. It can be understood that, because the precast beam slab is located at the section where the construction of the bridge is completed before hoisting, the precast beam slab is convenient to level and detect whether the precast beam slab is kept horizontal before hoisting, and specifically, whether the precast beam slab is kept horizontal can be detected through a total station.
After the two trolleys hoist the precast beam plate, the controller 6 acquires the rising height of the two ends of the precast beam plate when the two trolleys 11 hoist the precast beam plate, and records the rising height as H1 and H2. After the two trolleys 11 hoist the precast beam slab, and before the two trolleys 11 move on the horn 12, the first signal transmitting module 3 and the second signal transmitting module 4 respectively transmit a first detection signal and a second detection signal to the plurality of signal detecting modules 5, the signal detecting modules 5 send the first detection signal and the second detection signal to the controller 6 after receiving the first detection signal and the second detection signal again, the controller 6 acquires the two signal detecting modules 5 receiving the strongest signals according to the strength of the signals received by the plurality of signal detecting modules 5, and the positions of the two signal detecting modules 5 are recorded as the position A and the position B respectively.
When two crane trolleys 11 move on the horn 12 from the third column 15 to the direction close to the first column 13 and hoist the precast beam slab to a position between two piers where the precast beam slab is to be installed, the first signal transmitting module 3 and the second signal transmitting module 4 respectively transmit the first detection signal and the second detection signal to the plurality of signal detecting modules 5 again, the signal detecting modules 5 send the first detection signal and the second detection signal to the controller 6 after receiving the first detection signal and the second detection signal again, the controller 6 acquires the two signal detecting modules 5 receiving the strongest signals according to the strength of the signals received by the plurality of signal detecting modules 5, and the positions of the two signal detecting modules 5 are recorded as the A1 position and the B1 position respectively.
