Technical Field
[0001] The utility model relates to the technical field of fluid loading and unloading, in particular to a safety protection structure for fluid loading and unloading. Background Art
[0002] In the petroleum and chemical industry, tank trucks are important logistics equipment. They ensure the safe and efficient transportation of various types of oil products from production sites to consumption sites.
[0003] When loading liquefied hydrocarbons, Class AB, Class B A and other fluids into tank trucks in petrochemical enterprises, the tank truck needs to cooperate with the loading and unloading crane pipe on the loading and unloading platform to transfer the fluid to the tank truck. Specifically, the tank truck first needs to drive to the loading and unloading crane position, and connect the loading and unloading crane pipe's own rotating joint with the rigid pipe and elbow, and align the liquid outlet with the feed port above the tank truck, so as to realize the transmission of liquid medium between the tank truck and the trestle storage and transportation pipeline.
[0004] During the use of tank trucks and loading and unloading cranes, in order to ensure the normal operation of the cranes and improve loading and unloading efficiency, personnel are sometimes required to go to the tank trucks to replace worn parts, recalibrate the docking position, reinforce the structure, update seals, etc. There is often a height difference and gap between the loading and unloading platform and the feed port on the top of the tank truck.
[0005] However, there is no connecting protective structure between the existing loading and unloading platforms for fluids such as oil and tank trucks, which poses a great safety hazard when personnel move up and down between the loading and unloading platforms and tank trucks and operate. Therefore, an application is made to provide a safety protective structure for fluid loading and unloading, which improves the safety of personnel when they move up and down between the loading and unloading platforms and tank trucks, and does not hinder the tank trucks from entering or leaving the loading and unloading platforms.

When the second side rod 6 rotates and descends, each step 7 will follow and descend, and the two points between the step 7 and the first side rod 5 and the second side rod 6 rotate, so that the top surface of the step 7 can always remain horizontal, so that multiple step treads 7 form a step, which is convenient for people to go up and down. At the same time, when the step tread 7 descends, the connecting column 11 and the guardrail fixed to the step tread 7 will also follow and descend. Finally, the guardrail can be put on the outside of the feed port of the tank truck, and the personnel can be protected by the guardrail when standing on the tank truck for maintenance, thereby improving the safety of the operation.
[0023] The top end of the flip cylinder 3 is rotatably connected to the column 2, the bottom end of the piston rod of the flip cylinder 3 is rotatably connected to the L-shaped connecting rod 4, the L-shaped connecting rod 4 is fixedly connected to the first side rod 5, and a guide cylinder 8 is fixed on one side of the outer wall of the first side rod 5, and one end of the piston rod of the guide cylinder 8 is rotatably connected to the column 2.
[0024] A first fixed axis is provided at the connection between the step 7 and the first side rod 5, and a second fixed axis is provided at the connection between the step 7 and the second side rod 6. The rotating connecting plate 15, the step 7, the first side rod 5 and the second side rod 6 form a parallelogram structure. The four corners of the parallelogram structure are all rotatably connected. The step 7 is set in different numbers according to the height of the tank truck from the loading and unloading platform. Two rotating connection points are set at both ends of the step 7. When the entire safety protection structure is flipped, the step 7 will not rotate by itself, and the step 7 will be kept level, which is convenient for people to go up and down the stairs.
[0025] The guardrail includes: an upper guardrail 12 and a lower guardrail 13. The upper guardrail 12 is fixed to the outer side of the upper outer wall of the connecting column 11, and the lower guardrail 13 is fixed to the outer side of the lower outer wall of the connecting column 11. A vertical guardrail 14 is provided between the upper guardrail 12 and the lower guardrail 13. The guardrail is used to protect the outer side of the feed port of the tank truck to prevent people from falling and improve safety.
[0026] One side of the top of the connecting column 11 is connected to the second handrail rod 10 through a rotating shaft, one side of the lower half of the connecting column 11 is connected to the first handrail rod 9 through a rotating shaft, and the bottom end of the connecting column 11 is fixedly connected to the end outer wall of the step 7. Through the rotational connection between the connecting column 11 and the first handrail rod 9 and the second handrail rod 10, when the first side rod 5 and the second side rod 6 are flipped, the first handrail 9 and the second handrail 10 can be driven to flip through the connecting column 11, while keeping the vertical state of the connecting column 11 unchanged, so that the horizontal state of the guardrail fixed to the connecting column 11 remains unchanged.

By making the first handrail rod 9, the second handrail rod 10, the first side rod 5 and the second side rod 6 parallel to each other, the above four can change their angles synchronously when the whole mechanism is flipped, so that the step pedal 7 and the guardrail can always remain level.
[0028] When the safety protection device for fluid loading and unloading is used, the whole device is fixed above the loading and unloading crane position of the fluid loading and unloading platform through the loading and unloading platform connecting plate 1 and the column 2. When the staff needs to get on and off the tank truck, the turning cylinder 3 is started to extend the piston rod of the turning cylinder 3. Under the action of gravity, the second side plate 6 and its components will rotate and descend around the rotating shaft between the second side rod 6 and the column 2.
