Description

Technical Field

[0001] This utility model relates to the field of tank truck technology, specifically to a detachable sealing test tank cover device. Background Technology

[0002] Since tank trucks typically have one or more manholes on their tops for loading and unloading liquids and for personnel to enter and exit the tank, a sealing pressure test is required after welding and before proceeding to the next process to ensure the tank's airtightness. Before the test, the manholes must be sealed and the test medium added. Existing tank cover sealing devices are blind cover structures, sealed to the manholes with multiple bolts. Each test requires repeatedly disassembling and reassembling 16-20 bolts, resulting in low efficiency and significantly impacting operational efficiency. To improve the sealing efficiency of the tank manholes and simplify the workload, there is an urgent need to design a detachable tank cover sealing device that can effectively solve this problem.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 5 As shown: A detachable sealing test tank lid device includes a manhole cover sealing plate assembly 1 that can effectively fit the manhole of the tank and have a good sealing effect, and a locking mechanism 2. The locking mechanism 2 includes a locking screw assembly and a locking hook assembly. The locking screw assembly is connected to the manhole cover sealing plate assembly. One end of the locking hook assembly is connected to the cover plate 1.1 of the manhole cover sealing plate assembly, and the other end of the locking hook assembly is connected to the locking screw assembly. The locking hook assembly moves along the locking hook guide plate 2.7 under the action of the up and down movement of the locking screw. When the locking hook moves to the outermost position, it can effectively lock the manhole.

[0028] The manhole cover sealing plate assembly 1 includes a cover plate 1.1, a rubber gasket 1.2 and a pressure plate 1.3. The bottom of the cover plate 1.1 is provided with a pressure plate 1.3, and the outer side of the pressure plate 1.3 is provided with a rubber gasket 1.2 that plays a sealing role. The cover plate and the rubber gasket are provided with multiple threaded holes at corresponding positions, which facilitate the installation of studs and the fixing of the locking hook assembly.

[0029] The locking screw assembly includes a torsion bar 2.1, a locking screw 2.2, a threaded sleeve 2.3, and a locking hook guide plate 2.7. The torsion bar 2.1 is connected to the upper end of the locking screw 2.2. The locking screw 2.2 is internally threaded with the threaded sleeve 2.3. The threaded sleeve needs to be machined with internal threads. The locking screw 2.2 is screwed into the threaded sleeve 2.3 and is suspended by rotating the torsion bar 2.1. Multiple locking hook guide plates 2.7 are evenly provided on the outer side of the end of the threaded sleeve for guiding the movement of the locking hook. The locking screw 2.2 and the threaded sleeve are sealed by a sealing sleeve 2.4 and a sealing ring 2.5. A plug plate 2.9 is provided at the end of the threaded sleeve.

[0030] The locking hook assembly includes a locking hook bracket 2.6 and a locking hook 2.8. One end of the locking hook bracket 2.6 is connected to the bottom wall of the cover plate 1.1 of the manhole cover sealing plate assembly 1. One side of the locking hook 2.8 is connected to the locking hook bracket 2.6 via a pin 2.10, and the other side of the locking hook 2.8 is connected to the locking hook guide plate 2.7 of the locking screw assembly via a pin. The side wall of the locking hook guide plate 2.7 is provided with a sliding hole, and one side of the locking hook is slidably connected to the sliding hole via a pin. The locking screw 2.2 drives the locking hook 2.8 to move within the range of motion defined by the locking hook guide plate 2.7 by rotating the torsion bar 2.1. When the locking hook is locked, it can seal the manhole of the tank.

[0031] When the locking screw 2.2 rotates to its final position, the locking hook 2.8 moves to its outermost position under the guidance of the locking hook guide plate 2.7, and seals the manhole of the can lid through tension. When the locking screw rotates to its uppermost position, the locking hook moves to its innermost position under the guidance of the locking hook guide plate, and the device is removed by releasing the tension.

[0032] To facilitate water filling of the tank, a water filling assembly 3 is also provided on the cover plate. The water filling assembly 3 includes a male connector 3.1, a ball valve 3.2, and a water inlet pipe 3.3. One end of the water inlet pipe 3.3 is connected to the manhole cover sealing plate assembly 1, and the other end of the water inlet pipe 3.3 is equipped with a ball valve 3.2 and a male connector 3.1. The male connector 3.1 connects to an external female connector, allowing the test medium to be added to the tank via an external pumping system. When the ball valve is closed, the connection between the inside and outside of the tank's manhole is completely isolated. By providing a water filling assembly, the need for a separate water filling pipe is avoided, and the use of a universal male connector design improves work efficiency.

[0033] In order to display the pressure inside the tank in real time and improve the accuracy of the test, a pressure display device 4 is provided on the cover plate. The pressure display device 4 includes a pointer pressure gauge 4.1 and a monofilament tube 4.2. The pointer pressure gauge is connected to the cover plate through the monofilament tube and should be able to display the pressure inside the tank in real time, which solves the problem of repeatedly disassembling and assembling the pressure gauge in the past.

[0034] The cover plate is equipped with handles 5 for easy gripping. The symmetrical design of the double handles makes it easier to pick up and transport the device by holding it with both hands.

[0035] This utility model has a novel design, simple structure, is easy to install and disassemble, has a good sealing effect, and is highly efficient, thus having a large market demand.
