[0002] The problem of the safety and durability of bridges has always attracted people's attention. Engineering bridges need to be regularly inspected, and various structural data of the bridges during use are collected, analyzed and verified, so as to obtain the operation conditions of the bridges, provide a basis for the regular maintenance and management decisions of the bridges. If we want to realize the relevant evaluation of the bridge operation state and master the first-hand data of the bridge operation state, we need to regularly detect the damage state and stress state of each component of the bridge structure.

[0022] In one embodiment, as Figures 1-5As shown in the figure, a water bridge detection platform includes a hull 1. There is a guardrail 2 on the top surface of the hull 1. A lifting component 3 is installed in the middle of the top surface of the hull 1. The guardrail 2 is installed on the top of the lifting component 3. The left side of the top of the hull 1 is fixedly connected with a first connecting plate 4. Two connecting rods 5 are fixedly connected to the left side of the first connecting plate 4 and the left side of the guardrail 2 respectively. The two connecting rods 5 are arranged front and back opposite to each other. The left sides of the two front and back opposite connecting rods 5 are jointly fixedly connected with a fixing component 6. The right side of the top surface of the hull 1 is fixedly connected with a second connecting plate 7. The right side of the second connecting plate 7 is fixedly connected with a connecting component 8.

[0023] In order to be able to lift the guardrail 2 up and down, the lifting component 3 includes a scissor folding arm 31. Connecting blocks 32 are hinged to the left ends of the top and bottom of the scissor folding arm 31 respectively. The two connecting blocks 32 are fixedly connected to the left side of the top surface of the hull 1 and the left side of the bottom surface of the guardrail 2 respectively. Track plates 33 are fixedly connected to the right side of the top surface of the hull 1 and the right side of the bottom surface of the guardrail 2 respectively. Sliding plates 34 are hinged to the right ends of the top and bottom of the scissor folding arm 31 respectively. The two sliding plates 34 are respectively slidably connected to the surfaces of the upper and lower track plates 33. A hydraulic rod 35 is hinged to the left side of the top of the hull 1 and close to the front side. The upper end of the hydraulic rod 35 is hinged to the middle of the scissor folding arm 31.

[0024] In order to be able to clamp and fix the device on the bridge pier to prevent the hull 1 from moving along with the flow of water, the fixing component 6 includes a connecting frame 61. The right side of the connecting frame 61 is fixedly connected to the left sides of the adjacent two connecting rods 5. A bidirectional screw 62 is jointly connected by bearings to the front and back sides inside the connecting frame 61 and close to the top. Movable blocks 63 are threadedly connected to the front and back ends of the surface of the bidirectional screw 62. Fixed blocks 64 are fixedly connected to the left sides of the two movable blocks 63. Clamping grooves 65 are opened on the opposite surfaces of the two fixed blocks 64.

[0025] In order to facilitate driving the bidirectional screw 62 to rotate, a motor 66 is fixedly connected to the right side inside the connecting frame 61 and close to the front side through a frame. A driving gear 67 is fixedly connected to the shaft of the motor 66. A driven gear 68 is fixedly connected to the middle of the surface of the bidirectional screw 62. The driving gear 67 meshes with the driven gear 68.

[0026] In order to limit the fixed blocks 64 so that they will not rotate along with the bidirectional screw 62, guide rods 69 are fixedly connected to the middle of the opposite surfaces of the two fixed blocks 64. One ends of the guide rods 69 are respectively movably sleeved on the front and back sides of the connecting frame 61.

[0027] In order to conveniently connect the hull 1 on two devices into a whole, the connecting assembly 8 includes two connecting screws 81, which are arranged front and back relative to each other. The left end face of the connecting screw 81 is fixedly connected to the right side of the second connecting plate 7. A connecting screw tube 82 is threadedly connected to the right end of the surface of the connecting screw 81, and a hexagonal nut 83 is fixedly connected to the middle of the surface of the connecting screw tube 82.

[0028] In order to ensure that the upper fixing assembly 6 clamps the bridge section without affecting the up and down movement of the guardrail 2, several connecting seats 9 are fixedly connected in the clamping grooves 65 on the two upper fixing blocks 64, and a roller 10 is rotatably connected to the connecting seat 9.

[0029] Working principle: When the present utility model is in use, first, the hull 1 is moved close to the bridge pier, and the connecting frame 61 is sleeved on the pier. Then, the motor 66 is started. The motor 66 drives the driving gear 67 to rotate, the driving gear 67 drives the driven gear 68 to rotate, the driven gear 68 drives the bidirectional screw 62 to rotate, and the bidirectional screw 62 rotates to make the two movable blocks 63 move towards each other, so that the movable blocks 63 clamp on the surface of the pier through the clamping grooves 65, thereby fixing the hull 1 and preventing the hull 1 from moving easily. Then, the hydraulic rod 35 is started, and the extension of the hydraulic rod 35 drives the scissor folding arm 31 to unfold and push the guardrail 2 upward. The rollers 10 in the clamping grooves 65 on the upper fixing blocks 64 ensure that the upper fixing assembly 6 clamps the pier while not affecting the up and down movement of the guardrail 2. The connecting screws 81 on two adjacent devices are threadedly connected to both ends of the same connecting screw tube 82, connecting the two devices into a whole, thereby further improving the stability of the device and enabling the fixation of the devices that are not close to the pier to prevent them from moving along with the water flow.

[0030] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0031] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
