[0026] Second rotating shaft 7: connecting the upper and lower hinges 5, realizing the effective transmission of force in the vertical direction and the angle transformation, the rotation characteristic is the key to realize the height adjustment of the operating handle 12.

[0027] Butter nozzle 8: vertically installed on the side surface of the shaft sleeve 9 upwards, facilitating regular injection of lubricating grease, ensuring that the rotating friction between the shaft sleeve 9 and the third rotating shaft 10 is minimized, maintaining the smoothness of the device operation and reducing component wear.

[0028] Shaft sleeve 9: sleeved outside the third rotating shaft 10 and rotationally connected thereto, one end fixed with a limiting plate 11, providing stable support and rotation guide for the third rotating shaft 10, while protecting the rotating shaft from external force impact.

[0029] Third rotating shaft 10: one end fixed with an operating handle 12, as a component carrier for direct force exertion by the operator, converting human power into torque to drive the valve connection joint to control the opening and closing of the valve.

[0030] Limiting plate 11: fixed at one end of the shaft sleeve, preventing excessive axial displacement of the third rotating shaft 10, ensuring the accuracy and safety of the operation, and avoiding device failure caused by excessive shaft movement.

[0031] Operating handle 12: ergonomically designed for easy holding and exertion by the operator, with a reasonable lever ratio design to allow the user to easily control the valve, and the surface is treated with anti-slip to prevent slipping.

[0032] Connecting plate 13: the bottom end is fixed with a support channel steel 14, and the top end is connected with the shaft sleeve 9, serving as a connecting transition, stably connecting the shaft sleeve limiting structure and the tank support structure.

[0033] Support channel steel 14: firmly fixed with the tank surface, providing solid bottom support for the entire valve control device, ensuring stable operation of the device under various working conditions and resisting external force impact.

[0034] Working principle: when installing, the valve connecting plate 1 and the vehicle body are accurately fixed according to the predetermined position, ensuring firm connection, the tightening torque of the bolts reaches the design requirement, preventing loosening; the upper end of the support plate 4 is welded to the corresponding position below the valve connecting plate 1, the welded part is detected for flaw detection to ensure the welding quality, then the bottom surface of the support plate 4 is tightly attached to the outer surface of the tank and fixed, which can be welded or connected with high-strength bolts;

[0035] The one end of the valve connecting joint 2 is firmly connected with the opening and closing of the controlled valve through the selected welding or bolt connection, and the welding is uniform and full, and the bolt connection needs to add a lock washer; the first rotating shaft 3, the hinge 5, the second rotating shaft 7, the joint 6, the third rotating shaft 10 and the shaft sleeve 9 are assembled in sequence, the rotating shafts are flexible, the hinge connection is tight and not jammed, and the limiting plate 11 at one end is fixed after the shaft sleeve 9 is installed in place; the operating handle 12 is fixed at one end of the third rotating shaft 10, the connection is reliable, and the direction of the operating handle 12 is convenient for the operator to operate; finally, the upper end of the connecting plate 13 is welded with the shaft sleeve 9, the lower end is fixed with the supporting channel steel 14, and the supporting channel steel 14 is firmly connected with the surface of the tank body, and the installation of the whole device is completed.

[0036] In use, the operator holds the operating handle 12, applies appropriate force according to the opening and closing requirement of the valve, rotates the operating handle clockwise or according to the actual valve design direction to open the valve, and rotates the operating handle counterclockwise to close the valve.

[0037] During rotation, the first rotating shaft 3, the second rotating shaft 7, the third rotating shaft 10 and the hinge 5 work together to convert the rotary motion of the operating handle into the rotary motion of the valve connecting joint 2, so as to realize precise opening and closing control of the valve. During operation, the valve state is observed to ensure that the valve is completely opened or closed in place, and excessive force is avoided to cause damage to the parts.

[0038] Beneficial effects: The connection of the remote operating mechanism enables the operator to control the valve at the top of the tank on the ground. On the one hand, it avoids the operator to work at the top of the tank, and on the other hand, it saves the time of the operator to go up and down the tank, which brings great convenience to the operator, ensures the safety of the operator and saves the time cost.

[0039] Secondly, during the operation of the semitrailer, one person needs to operate the valve at the top of the tank, and another person needs to observe the data or the state of the tank truck on the ground. Through the remote operating mechanism of the present application, it is expected to improve the possibility of one person to operate the semitrailer, and to control the opening and closing of the valve more quickly after observing the data or the state of the semitrailer, thereby improving the response time and reducing the labor cost.

[0040] Thirdly, during the design of the semitrailer tank, some valves are installed at the front end of the tank. In order to protect the operator operating such valves on the tank top, the tank top protection device needs to cover the entire tank top. However, when manholes and other tank top accessories are concentrated at the rear end of the tank, and a certain valve is installed at the front end of the tank, if the remote operating mechanism of the present application is used, the tank top protection device does not need to be extended to the front end of the tank. This not only saves the manufacturing cost of the semitrailer, but also is more conducive to the rapid response of the tank top protection device.

[0041] Finally, the remote control mechanism of the present application selects stainless steel for the valve connecting plate, the valve connecting joint, the support plate of the upper part, and the operating handle, the support channel steel, and the connecting plate of the lower part. The rotating shaft of the middle part is made of carbon fiber material, which is lighter. On the one hand, it is considered for the lightweight design of the vehicle, and on the other hand, it is to reduce the force of the operator controlling the operating handle, and to open and close the valve more quickly.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features.
