Technical Field

[0001] The utility model relates to the technical field of sealing detection devices, in particular to a sealing detection device for an inner cabin of a steel trestle board. Background Art

[0002] A steel trestle is a temporary steel structure bridge, primarily used to replace existing bridges for transportation during bridge construction or repair. Typically constructed of steel, it offers high load-bearing capacity and stability, allowing for rapid erection and dismantling, making it ideal for temporary bridge applications. Steel trestles are widely used in construction, particularly in emergency situations requiring rapid bridge erection, such as large-scale projects spanning seas, rivers, and rivers.

[0003] In the existing technology, when steel trestle boards are produced, the surface of the steel trestle boards is generally coated with anti-rust paint for rust prevention. The interior of the steel trestle boards is formed by a supporting pipe warehouse to form an inner cabin. The main function of the inner cabin is to support and reinforce the bottom of the steel trestle boards. It is also sprayed with anti-rust paint. However, when the sealing of the inner cabin is poor, water and water vapor will enter the interior, causing rust inside the inner cabin, which in turn affects the service life of the steel trestle boards. Therefore, a steel trestle board inner cabin sealing detection device is urgently needed to solve the above problem. Utility Model Content

The limit plate 4 is movably socketed, and the external hook of the hook of the lifting gantry 2 crane is hooked with a hook scale 7, the model of the hook scale 7 is Yousheng-OCS-5T, and the external hook of the hook of the hook scale 7 is hooked with a lifting ring 8, and the lifting ring 8 is fixedly installed with the mobile frame 5. A plurality of second fixing holes 12 are provided on the top surface of the mobile frame 5, and a plurality of small electric hoists 13 are fixedly installed on the top surface of the mobile frame 5, and the small electric hoist 13 is electrically connected to the PLC controller.

[0023] In this embodiment, a second fixing plate 9 is fixedly installed on the bottom surface of the limiting plate 4, and two first fixing holes 10 are provided on the top surface of the second fixing plate 9. The inner circular wall of the first fixing hole 10 is fixedly sleeved with an electric push rod 11. A lower pressure plate 16 is provided on the bottom surface of the second fixing plate 9. The lower pressure plate 16 is fixedly installed on the bottom surface of the drive shaft of the electric push rod 11. The electric push rod 11 is electrically connected to the PLC controller. A placing table 15 is provided on one side of the water pool 14. Rectangular grooves are respectively provided on both sides of the inner part of the limiting hole 6, and a rotating wheel 17 is fixedly sleeved inside the rectangular groove.

[0024] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: through the water inlet pipe 20, when the user needs to perform a sealing test on the steel trestle board body 1, the water inlet pipe 20 is used to fill the interior of the pool 14 with water about three-quarters, and then the crane slide of the lifting gantry 2 is started to move, so as to drive the first fixed plate 3, the movable frame 5 and the lifting hook 18 to move to the top surface of the placement table 15, and the steel trestle board body 1 is hooked by the lifting hook 18 and a number of small electric hoists 13 are started to hook each corner of the steel trestle board body 1 and lift it, thereby lifting the steel trestle board body 1 Move to the top surface of the water pool 14. At this time, the hook scale 7 is used to weigh the lifting ring 8, the mobile frame 5, the small electric hoist 13 and the steel trestle board body 1, and the numbers are recorded. Thus, the crane of the lifting gantry 2 is started to make the mobile frame 5 move downward under the limit of several limit plates 4. During the movement, the rotating wheel 17 is rotated to make the limit hole 6 and the limit plate 4 move smoothly. Then, after the steel trestle board body 1 is placed in the water, the electric push rod 11 is started to push the lower pressure plate 16 downward to press the steel trestle board body 1 in the water into the water. Note that the steel trestle should be pressed first at this time. The front side of the bridge board body 1 is pressed, and then the rear side is pressed to tilt the steel trestle board body 1, so that water enters the bottom cavity. Then, the crane of the lifting gantry 2 is started to lift the steel trestle board body 1, so that the steel trestle board body 1 is out of the water and remains suspended. At this time, observe whether the weighing data of the hook scale 7 increases (an error of 0.1kg is allowed), and observe whether the outside of the steel trestle board body 1 is leaking. When water is observed to flow out continuously and the weighing data of the hook scale 7 is continuously reduced, it can be judged that water has entered the interior of the steel trestle board body 1. Otherwise, the sealing is good. Then, the front and rear two small electric hoists 13 are started to release the ropes alternately. When the rope is pulled in, the steel trestle board body 1 tilts back and forth. If the sound of shaking water is heard, it is further proved that water has entered. After the internal water flows out, the steel trestle board body 1 is moved and placed on the top surface of the placement table 15, thereby comprehensively achieving the effect of sealing detection of the steel trestle board body 1. The sealing of the steel trestle board body 1 can be judged by placing the steel trestle board body 1 in water and lifting it to determine whether the weight changes significantly and whether water is continuously flowing outside. The sealing of the steel trestle board body 1 can also be judged by shaking the steel trestle board body 1 and making the sound of water stopping. If the sealing is poor, it can be further reworked, which ensures the quality of the steel trestle board body 1 and is more practical.
