[0024] like Figures 1-7 As shown, this invention discloses a surveying device for synchronous construction of towers and beams, such as... Figure 1 As shown, this measuring device can be used in the construction of bridge towers with vertical and horizontal sides. During bridge construction, as the bridge tower is moved upwards, the crossbeams on both sides of the tower extend outwards simultaneously. Each stage of bridge tower construction requires two parts: a vertical tower planning section 1 and a crossbeam length planning section 2. The two vertical tower planning sections 1 are located on both sides of the bridge tower, and the two crossbeam length planning sections 2 are located on the top side of the extension ends of the two crossbeams.

Figure 6 and Figure 7 As shown, the bridge tower vertical planning part 1 includes a launching seat 11 and a receiving seat 12, the launching seat 11 is fixed on the side of the bridge tower extension end, the launching seat 11 is a steel base plate, which is fixed on the side of the bridge tower by screws, the fixing of the launching seat 11 can be realized by drilling holes on the side of the bridge tower, the launching seat 11 includes a launching head 111, the launching head 111 extends from the outside of the launching cylinder, the launching head 111 is provided with a first infrared launching cylinder 112 downward, the launching head 111 is also fixed with a pull rope 13, the receiving seat 12 is provided with a clamping part 121 for clamping the pull rope 13 and a first infrared receiving head 122 for receiving the signal of the first infrared launching cylinder 112, the receiving seat 12 is also fixed on the side of the bottom end of the bridge tower by screws, and the first infrared launching cylinder 112 is arranged upward.

[0025] When using this measuring device, with the synchronous construction of the tower beam, the launching seat 11 is fixed on the side of the uppermost end of the bridge tower by screws, the receiving seat 12 clamps the pull rope 13 by the clamping part 121, and the receiving seat 12 is suspended and located at the bottom end of the bridge tower, under the action of gravity, the receiving seat 12 straightens the pull rope 13, if the receiving seat 12 is too far away from the side of the bridge tower at this time, it can prompt the serious deflection of the bridge tower, if the receiving seat 12 is close to the side of the bridge tower at this time, the receiving seat 12 is fixed on the side of the bottom end of the bridge tower by screws, so that the receiving seat 12 is located in the signal receiving area, the first infrared launching cylinder 112 vertically downward launches an infrared signal, if the first infrared receiving head 122 receives the infrared signal, it can ensure the construction state of the bridge tower vertically extending upward, if the first infrared receiving head 122 suddenly cannot receive the infrared signal during the construction process, the bridge tower changes from the vertical state to the deflection state, which can prompt the deformation of the bridge tower for subsequent maintenance and repair; this bridge tower vertical planning part 1, as a planning device for the upward construction of the bridge tower, can measure and prompt the upward extending state of the bridge tower at each stage of the upward construction of the bridge tower; correspondingly, the beam length planning part 2 receives the infrared signal of the second infrared launching cylinder 23 by rotating the second infrared launching cylinder 23, the difference between the angles of rotation of the second rotating seats 22 of the beam length planning parts 2 on both sides needs to be within a reasonable control range, which can prompt the construction length of the beams on both sides to be within a length stage; this measuring device can measure, plan and prompt the verticality of the upward construction of the bridge tower and the synchronous degree of the extension of the beams on both sides during the synchronous construction of the bridge tower by setting the bridge tower vertical planning part 1 and the beam length planning part 2, as a data prompting device, it can instantly understand the state of the synchronous construction of the bridge tower, and ensure the safety and stability of the synchronous construction of the bridge tower.

[0026] In further proposals, such as Figure 6 and Figure 7 As shown, the vehicle body 21 is provided with a second drive motor 24, and the end of the second drive motor 24 is provided with a second gear 25. The second gear 25 meshes with a second rotating seat 22. The second rotating seat 22 is coaxially provided with a rotating shaft 26. The two ends of the rotating shaft 26 are rotatably mounted on the vehicle body 21. One end of the rotating shaft 26 extends out of the vehicle body 21 and is fixedly connected to an indicator needle 27. The vehicle body 21 is provided with an angle scale line 28 on the surface through which the indicator needle 27 extends. The extension direction of the indicator needle 27 is the same as the orientation of the second infrared emitting tube 23.

[0027] In this structure, the second drive motor 24 can quickly drive the rotation of the second rotating base 22. When the second infrared receiver head 118 receives the infrared signal, the second drive motor 24 stops rotating, and the indicator needle 27 stops with the second rotating base 22, indicating the corresponding angle position on the angle scale line 28. This structure can represent the rotation angle of the second infrared emitting tube 23 in a very concrete way, providing the construction personnel at the extension end of the crossbeam with an instant and easy-to-understand angle signal. During the construction of the crossbeam, it can serve as data information that needs attention, reminding the construction personnel of the current crossbeam construction length status, thus achieving the functions of prompting and standardization.

[0028] In further proposals, such as Figure 2 and Figure 3 As shown, a first rotating base 113 is rotatably mounted on the transmitter head 111, and the first infrared transmitter tube 112 is fixed on the side of the first rotating base 113. A counterweight block 1121 is fixed on the outside of the first infrared transmitter tube 112, and the counterweight block 1121 pulls the first infrared transmitter tube 112 vertically downward.

[0029] This structure ensures that the first infrared emitting tube 112 always faces downwards. When encountering unevenness on the side of the tower beam, the fixation of the emitting base 11 itself will cause a slight tilt of the emitting head 111. During the construction of long bridge towers, even a slight tilt can lead to inaccurate measurement data for this measuring device. Therefore, by setting the first infrared emitting tube 112 to be oriented with gravity in the positive direction, and making the orientation of the first infrared emitting tube 112 parallel to the extension direction of the pull rope 13, the effect of the fixed tilt of the emitting base 11 caused by the unevenness on the side of the tower beam can be offset.

[0030] In further proposals, such as Figure 2 and Figure 3As shown, the launching seat 11 is provided with a sliding groove 114, the launching head 111 is transversely arranged in the sliding groove 114, the launching head 111 is provided with a rack 1141, the sliding groove 114 is provided with a first driving motor 115, the first driving motor 115 is provided with a first gear 116 at the end, and the first gear 116 is engaged with the rack 1141.

[0031] The structure is used as the fine adjustment device of the first infrared launching cylinder 112 and the first infrared receiving head 122. When the receiving seat 12 is fixed, the left and right deflection of the receiving seat 12 caused by vibration and force can be avoided by driving the launching head 111 to slide left and right in the sliding groove 114, so that the first infrared receiving head 122 can receive the launching signal of the first infrared launching cylinder 112, and the subsequent verticality detection can be performed.

[0032] In a further scheme, as shown in Figure 4 and Figure 5 The launching head 111 is provided with two vertical columns 117, the pulling rope 13 is provided with two ropes and is fixed to the vertical columns 117 respectively, the receiving seat 12 includes a shell 123, the shell 123 is provided with a guide hole 1231 at the upper and lower ends for the pulling rope 13 to pass through, the clamping part 121 includes a middle seat 1211, the middle seat 1211 is provided with an outer seat 1212 on both sides respectively, the outer seat 1212 is provided with a clamping screw, the end of the clamping screw is rotatably arranged in the middle seat 1211, the shell 123 is provided with a gap slot 1232 for the movement of the locking screw 1213, the clamping screw is tightened, the outer seat 1212 and the middle seat 1211 clamp the pulling rope 13, the shell 123 is further provided with a guide column 1215, the middle seat 1211 is slidably arranged on the guide column 1215, the shell 123 is further rotatably provided with a tightening screw 1214, the tightening screw 1214 is threadedly connected to the guide column 1215, and the tightening screw 1214 is rotated to move the middle seat 1211 on the guide column 1215.

[0033] In this structure, the two pulling ropes 13 can avoid the rotation of the receiving seat 12 when it is suspended, the length of the pulling rope 13 should be longer than the overall height of the tower beam, the pulling rope 13 passes through the guide hole 1231, and the clamping screw is tightened to clamp the two outer seats 1212 and the middle seat 1211 to adjust the position of the receiving seat 12 on the pulling rope 13, so that the receiving seat 12 is located at the bottom of the tower beam, and the receiving seat 12 is fixed on the side of the bridge tower, and the pulling rope 13 can be tightened by tightening the tightening screw 1214, so that the receiving seat 12 and the launching seat 11 can be used as a prompt symbol for the deflection of the tower beam when the pulling rope 13 is broken or loosened in the subsequent construction process.

[0034] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail by the above preferred embodiments, those skilled in the art should understand that various modifications can be made in form and details thereof without departing from the scope defined by the appended claims of the present application.
