Description

Technical Field

[0001] The utility model relates to the field of bridge detection equipment, and more specifically, to a telescopic arch climbing inspection vehicle for a basket-type arch bridge. Background Art

[0002] At present, bridges with arch rib structures mainly include parallel arch bridges and basket arch bridges. As the name suggests, the two arch ribs of a parallel arch bridge are parallel to each other, and the distance between the two arch ribs is a fixed value. However, the middle parts of the two arch ribs of a basket arch bridge are close to each other, so the distance between the two arch ribs is not fixed. From the two sides to the middle, the distance between the two arch ribs gradually decreases. This makes it difficult to inspect and maintain the basket arch bridge. When the inspection equipment walks on the arch ribs, it not only needs to be able to adapt to the changes in the distance between the two arch ribs, but also needs to have the function of inspecting the sides and bottom of the arch ribs at the same time.

[0018] Figure 1-Figure 2 A telescopic arch climbing inspection vehicle for a basket-type arch bridge provided in an embodiment of the utility model comprises a frame 1, two sliding seats 2, two groups of longitudinal walking mechanisms and three hanging baskets 3, two groups of first transverse walking mechanisms 4 and three groups of second transverse walking mechanisms are alternately arranged on the frame 1, the two sliding seats 2 are respectively connected to the two groups of first transverse walking mechanisms 4 in transmission, the two groups of longitudinal walking mechanisms are respectively arranged at the lower ends of the two sliding seats 2, and are respectively slidably connected to the two arch ribs of the arch bridge, and the lower ends of the second transverse walking mechanisms are connected to the hanging baskets 3.

[0019] In this embodiment, two sets of longitudinal walking mechanisms are respectively arranged on two arch ribs, and can move along the length direction of the arch rib, that is, the length direction of the arch bridge, with this as the longitudinal direction, the sliding seat 2 connected to the two sets of longitudinal walking mechanisms can be driven to move, and the sliding seat 2 is respectively connected to the two sets of first transverse walking mechanisms 4, so that the frame 1 can be driven to move along the length direction of the arch rib by the two sets of longitudinal walking mechanisms. Since the distance between the two arch ribs is variable, when the frame 1 moves along the length direction of the arch rib, the two sets of first transverse walking mechanisms 4 drive the two sliding seats 2 to slide on the frame 1 along the width direction of the arch bridge, with this as the transverse direction, at this time, the frame 1 is kept stationary in the width direction of the arch bridge, and the two sets of first transverse walking mechanisms 4 drive the two sliding seats 2 to slide, and drive the two sets of longitudinal walking mechanisms to move transversely, so that the two sets of longitudinal walking mechanisms can always be slidably connected with the two arch ribs, so that the frame 1 can move longitudinally on the arch rib. During the movement of the vehicle frame 1, the three hanging baskets 3 are driven to move longitudinally. The three hanging baskets 3 are respectively located between the two arch ribs and on both sides, so that the maintenance personnel can stand in the hanging baskets 3 and perform a comprehensive maintenance on the bridge arch ribs. Due to the special shape of the arch ribs, different parts thereof are different in the horizontal and vertical directions, so the positions of the hanging baskets 3 in the horizontal and vertical directions also need to be adjusted during the maintenance process. At this time, the second transverse walking mechanism and the lifting mechanism are used to drive the hanging baskets 3 to move horizontally and up and down respectively, so as to adjust the height and the transverse position of the hanging baskets 3 so that they are close to the arch ribs. The vehicle frame 1, the first transverse walking mechanism 4 and the second transverse walking mechanism are all common equipment in existing bridge inspection vehicles, and the existing technology can be used, and no further description is given here. The vehicle frame 1 can adopt an aluminum alloy truss structure to reduce the weight of the vehicle frame 1.

[0020] Preferably, as another embodiment of the present utility model, Figure 3 As shown, the longitudinal walking mechanism includes a track 5, a bracket 6 and a moving trolley 7. The track 5 is arranged at the upper end of the arch rib along the direction of the arch bridge. The bracket 6 is transmission connected to the first transverse walking mechanism 4. The moving trolley 7 is arranged on the bracket 6 and is slidingly connected to the track 5.

[0021] In this embodiment, the mobile trolley 7 slides on the track 5, and the first transverse walking mechanism 4 drives the bracket 6 to move transversely, thereby ensuring the stability of the connection between the mobile trolley 7 and the track 5, thereby ensuring the stable operation of the longitudinal walking mechanism. The mobile trolley 7 is a common device in existing bridge inspection vehicles, and the existing technology can be used, and no further description is given here.

[0022] Preferably, as another embodiment of the present utility model, Figure 3 As shown, the bracket 6 is also provided with a plurality of auxiliary support wheels 8, and the auxiliary support wheels 8 are slidably connected to the arch ribs.

[0023] In this embodiment, a plurality of auxiliary support wheels 8 are provided on the bracket 6 , and the auxiliary support wheels 8 are slidably fitted with the surface of the arch rib, thereby increasing the stability of the bracket 6 .

[0024] Preferably, as another embodiment of the present utility model, Figure 4 As shown, two guide rails 9 are horizontally provided at the lower end of the frame 1, and three groups of electric hoist groups are slidably connected to the guide rails 9. Each group of the electric hoist group includes two electric hoists 10. The running trolley of the electric hoist 10 is slidably connected to the guide rails 9, and its wire rope is connected to the corresponding hanging basket 3.

[0025] In this embodiment, two guide rails 9 are arranged horizontally, and the three groups of electric hoist groups thereon are spaced apart in pairs horizontally. The four electric hoists 10 of the two groups of electric hoist groups spaced apart from each other are respectively located above four right angles of the same hanging basket 3, and their wire ropes are connected to the corresponding hanging basket 3. In this way, when the four electric hoists 10 work synchronously, the hanging basket 3 can be lifted and lowered, and when the running trolleys of the four electric hoists 10 work synchronously, the hanging basket 3 can be moved horizontally. The running trolleys of the four electric hoists 10 constitute a second horizontal walking mechanism, and the part other than the running trolley constitutes a lifting mechanism.

[0026] Preferably, as another embodiment of the present utility model, Figure 4 As shown, the hanging basket 3 is a foldable hanging basket 3.

[0027] In this embodiment, the hanging basket 3 is set as a foldable hanging basket 3, and the area of ​​the hanging basket 3 is enlarged, which can reduce the lateral movement of the hanging basket 3. The foldable hanging basket 3 is a common device in the existing bridge inspection vehicle, and the existing technology can be used, and it will not be repeated here.

[0028] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented.
