Below in conjunction with accompanying drawing, the specific implementation manner of this patent is described in further detail.

As shown in Fig. 1 and Fig. 5, the present invention proposes a bridge detection device, which includes two frames with the same structure and oppositely arranged, the frames are symmetrically installed on both sides of the box girder of the viaduct, and the frames include bridge decks Traveling car body 1, protective fence 2, lifting gantry 3, shaft truss 4, auxiliary workbench 5, lifting support device (lifting support device includes hydraulic baffle 6, support truss 7, hydraulic outrigger 8), main Working platform 9, docking device 10, lifting device (the lifting device is composed of lifting motor 11, steel wire rope 12, hanging basket 13, etc.), rotating device 14, the frame body is driven by the traveling car body 1 to walk on the box girder of the viaduct, A shaft truss 4 is installed below the hoisting gantry 3, and the integral body composed of the hoisting gantry 3 and the shaft truss 4 is installed on the traveling vehicle body 1, and the shaft truss 4 is arranged on the The lower side of the traveling vehicle body 1, the lower end of the shaft truss 4 is equipped with a horizontal main working platform 9 through a rotating device, and the main working platform 9 is arranged below the box girder of the viaduct, and the main working platform 9 can pass through the The rotating device is driven to rotate on a horizontal plane, and the end of the main working platform 9 is provided with a docking device 10. Connected, the lifting mast 3 is equipped with a lifting device.

Also installed on the shaft truss 4 is a horizontal auxiliary workbench 5, the auxiliary workbench 5 is arranged above the main work platform 9, and the shaft truss 4 is provided with a The vertical ladder of the auxiliary workbench 5, the auxiliary workbench 5 is arranged on both sides of the viaduct box girder.

The end of the auxiliary workbench 5 is equipped with a lifting support device, which includes a hydraulic baffle 6, a support truss 7 and a hydraulic support leg 8, and the hydraulic baffle 6 is arranged on the auxiliary workbench 5. end and the hydraulic baffle 6 can move outward along the direction of the auxiliary workbench 5 through a hydraulic device, the support truss 7 is installed between the ends of the two auxiliary workbenches 5, and the hydraulic support Legs 8 are installed at the bottom of said support truss 7 .

The lifting device is composed of a lifting motor 11, a steel wire rope 12, a hanging basket 13, etc. The lifting motor 11 is installed on the beam of the lifting gantry 3 through a lateral movement device, and the lifting motor 11 is connected with the steel wire rope 12. The hanging basket 13 is connected.

As shown in Figure 2, the docking device 10 is installed at one end of the main working platform 9. The docking device 10 is composed of a docking door frame 15 and a connecting pin shaft 16. There are four pin shafts in each pair of docking devices 10 to realize two parallel rows connect.

As shown in Figure 3, when crossing a bridge pier, the process is shown in Figure 3: a-b-c-d-e-f-g-h. First, the inspection vehicle approached the front and rear main working platforms of the bridge pier as shown in Figure 3(a); the front main working platform was disconnected and rotated to the open state as shown in Figure 3(b); the inspection vehicle walked forward until the front main working platform passed the bridge pier, As shown in Figure 3(c); the front main working platform is rotated and docked, as shown in Figure 3(d); the rear main working platform is disconnected, and each rotates to the open state as shown in Figure 3(e); the detection vehicle moves forward, as shown in Figure 3(f ); the rear main working platform passes the bridge pier, as shown in Figure 3(g); the rear main working platform is rotated and docked, as shown in Figure 3(h); in this way, the movement of the bridge inspection vehicle passing through the bridge pier is realized. The front and rear two pairs of main working platforms and their docking devices. The interlocking between two pairs of docking devices ensures that at least one pair of docking devices is always in a connected state, so that the two frame structures are connected as a whole, thereby ensuring the rigidity and stability of the entire structure.

During the cyclic transition process of the connection and unlocking working states of the docking device, the principle of "first in, last out, last in first out" is followed, and the action sequence of the left and right docking main working platforms cannot be synchronized. This design not only ensures good meshing when the device is connected, but also avoids interference when the device is docked. Note that the prerequisite for the disconnection, rotation and connection actions of the main working platform is that the vehicle body must be parked and braked when traveling on the bridge surface of the detection vehicle.

As shown in FIG. 1 , it is a schematic diagram of the detection operation of the high-speed railway viaduct detection and rescue operation vehicle. The inspection vehicle is parked on the box girder of the bridge, and two pairs of main working platforms are docked to form a stable overall structure; the vertical ladder installed in the shaft truss 4 can transport personnel and equipment to the auxiliary workbench 5; the hoisting motor 11 pulls the hanging basket 13 transport personnel and equipment to the main working platform 9 up and down, the specific process: after the hanging basket 13 is lowered to the designated position, the hanging basket doors on both sides are rotated down, and can be fixed with the main working platform on both sides, and the docking door The frame 15 mechanism is hollow, so the front, rear, left, and right main working platforms all realize penetration.

As shown in Figures 4 and 5, it is a schematic diagram of the detection and rescue work of the high-speed railway viaduct and rescue work vehicle. To realize this function, the lifting support device and the lifting device must be used together. The parking brake of the detection vehicle is at the position shown in the figure, and the front and rear two pairs of main working platforms span the two sides of the bridge pier, and the main working platforms 9 are docked and fixed. The hydraulic outrigger 9 moves to form a bearing point on the bridge pier, preventing the bridge deck from being subjected to excessive loads and destroying the original structure of the bridge. Simultaneously, the hydraulic damper 6 acts to further limit the lateral movement of the vehicle body and prevent the vehicle body from tilting. After doing so, the lifting device can move. The hoisting motor 11 pulls the hanging basket 13 up and down through the wire rope 12, and utilizes the hanging basket to transport personnel and materials between the bridge deck and the ground, thereby establishing an accident rescue channel.
