[0024] like Figure 1 As shown, an embodiment of the utility model provides a road and bridge construction device, including a frame 1, a mobile maintenance platform 4 and a driving mechanism 5. The frame 1 is used to be arranged on one side of a pier of a bridge 100. The extension direction of the frame 1 is consistent with the transverse direction of the bridge 100. The frame 1 is used to move along the longitudinal direction of the bridge 100. Two mobile maintenance platforms 4 are symmetrically arranged on both sides of the frame 1. The driving mechanism 5 is used to drive the two mobile maintenance platforms 4 to move synchronously toward each other or synchronously away from each other.

[0025] In this embodiment, by making the extension direction of the frame 1 consistent with the transverse direction of the bridge 100, the frame 1 can move along the longitudinal direction of the bridge 100, so that the staff can inspect the lower surface of one side of the bridge 100 and the side surface of the pier through the mobile inspection platform 4. The two mobile inspection platforms 4 are symmetrically arranged on both sides of the frame 1, so that two staff members can perform inspection operations at the same time. The driving mechanism 5 is used to drive the two mobile inspection platforms 4 to move synchronously towards each other or synchronously away from each other. In this way, not only can the two staff members simultaneously conduct a comprehensive inspection of the bridge 100 and the piers, but the real-time positions of the two mobile inspection platforms 4 are both at symmetrical points on the frame 1, thereby avoiding the safety risk of tilting caused by the uneven weight on both sides of the frame 1, thereby improving the safety during inspection.

[0026] like Figure 1 As shown, optionally, the vehicle frame 1 includes a vehicle body 11 and a reinforcing rod 12 , and the reinforcing rod 12 is connected to both sides of the vehicle body 11 .

[0027] In this embodiment, the reinforcing rods 12 can be welded to both sides of the vehicle body 11 , so that the overall structural strength of the vehicle frame 1 can be increased through the reinforcing rods 12 , thereby improving safety.

[0028] like Figure 1 As shown, optionally, the road bridge construction device also includes a first moving mechanism 2 and a first lifting mechanism 3. The first moving mechanism 2 is used to move along the embedded slide rail 110 on the lower surface of the bridge 100. The extension direction of the embedded slide rail 110 is the same as the direction along the bridge 100. The first moving mechanism 2 is connected to the middle part of the frame 1 through the first lifting mechanism 3.

[0029] In this embodiment, the first moving mechanism 2 is connected to the middle part of the frame 1 through the first lifting mechanism 3, that is, the first moving mechanism 2 and the first lifting mechanism 3 are located on the bisector of the frame 1. In this way, when the first moving mechanism 2 drives the frame 1 to move slowly through the first lifting mechanism 3, it can ensure that the frame 1 does not tilt, thereby improving the stability of the frame 1 when moving.

[0030] like Figure 1 and Figure 2 As shown, optionally, the first moving mechanism 2 is configured as an electric trolley.

[0031] like Figure 1 and Figure 2 As shown, optionally, the first lifting mechanism 3 is configured as a scissor-type lifting platform.

[0033] In this embodiment, the staff can carry tools and equipment into the vehicle basket 43 , and then the vehicle basket 43 is driven up by the second moving mechanism 41 , so that the staff can inspect the lower surface of the bridge 100 .

[0034] like Figure 1 and Figure 2 As shown, optionally, the second moving mechanism 41 is configured as an electric trolley, and the second lifting mechanism 42 is configured as a scissor-type lifting platform.

[0035] In this embodiment, the lower surface of the electric trolley is connected to one end of the scissors-type lifting platform, and the other end of the scissors-type lifting platform is connected to the frame 1. In this way, the electric trolley can drive the frame 1 and the mobile maintenance platform 4 on the frame 1 to move along the direction of the bridge 100, thereby realizing the maintenance of the lower surface of the bridge 100 and the side of the pier.

[0036] It should be noted that the second moving mechanism 41 can also be other self-propelled forms, such as a fuel-powered vehicle, and the second lifting mechanism 42 can also be a lifting device such as a winch.

[0037] like Figure 2 As shown, optionally, the driving mechanism 5 includes a forward and reverse threaded screw shaft 51 and a motor 52, the motor 52 is connected to the frame 1, the motor 52 is drivingly connected to the forward and reverse threaded screw shaft 51, the forward and reverse threaded screw shaft 51 is arranged along the extension direction of the frame 1, and the two second moving mechanisms 41 are respectively threadedly connected to the two sides of the forward and reverse threaded screw shaft 51.

[0038] Specifically, the forward and reverse threaded screw shaft 51 is configured as two sections of external threads with opposite rotation directions symmetrically around its own center. The motor 52 can be fixedly mounted on one end of the frame 1 by bolts. The output shaft of the motor 52 is connected to one end of the forward and reverse threaded screw shaft 51, and the other end of the forward and reverse threaded screw shaft 51 is rotatably connected to the other end of the frame 1. A slider is installed on the bottom surface of the second moving mechanism 41, which is the electric vehicle. The slider is provided with a threaded hole that is compatible with the external thread of the forward and reverse threaded screw shaft 51. In this way, the motor 52 can drive the forward and reverse threaded screw shaft 51 to rotate in the forward or reverse direction, thereby achieving the synchronous movement of the two second moving mechanisms 41 away from or close to each other.

[0039] like Figure 1 and Figure 2As shown, optionally, the road and bridge construction device also includes an anti-collision mechanism 7, which is arranged on the opposite surfaces of the two second moving mechanisms 41. The anti-collision mechanism 7 includes a spring 71 and a buffer plate 72. One end of the spring 71 is connected to the second moving mechanism 41, and the other end of the spring 71 is connected to the buffer plate 72.

[0040] In this embodiment, Figure 2 In the figure, the opposite surfaces of the two second moving mechanisms 41 refer to the left side surface of the right second moving mechanism 41 and the right side surface of the left second moving mechanism 41, and the buffer plate 72 on the right second moving mechanism 41 is arranged correspondingly to the buffer plate 72 on the left second moving mechanism 41. When the two second moving mechanisms 41 approach each other, the buffer plates 72 can contact each other and squeeze the spring 71, so that the two mobile maintenance platforms 4 will not collide, thereby improving safety.

[0041] like Figure 1 and Figure 2 As shown, optionally, the inner bottom surface of the vehicle body 11 is connected with a guide rail 6, and the wheels of the electric vehicle are rollingly connected to the guide rail 6.

[0042] Specifically, the guide rail 6 can be fixed to the inner bottom surface of the vehicle body 11 by bolts, and the guide rail 6 can also be fixed to the inner bottom surface of the vehicle body 11 by welding, so that the wheels of the electric vehicle roll on the guide rail 6, thereby making the electric vehicle move more smoothly.
