Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning vehicle-mounted gas cylinders, and particularly relates to a cleaning line and method for automatically cleaning vehicle-mounted gas cylinders. BACKGROUND

[0002] A vehicle-mounted gas cylinder is usually installed at the bottom of a transport vehicle or truck, and is used to contain high-pressure natural gas or hydrogen. The vehicle-mounted gas cylinder is formed by mechanical hydraulic stretching, and the structure of the vehicle-mounted gas cylinder is shown in FIG. 1. Figure 1 After the vehicle-mounted gas cylinder is formed by stretching, a large amount of oil stains is attached to the inner wall of the vehicle-mounted gas cylinder. Therefore, after a batch of vehicle-mounted gas cylinders are formed by stretching, the oil stains attached to the inner wall of the cup-shaped body of the vehicle-mounted gas cylinder are required to be cleaned by using a cleaning liquid.

[0003] The method for cleaning the vehicle-mounted gas cylinder in a workshop is as follows: a worker first hoists up a vehicle-mounted gas cylinder by using a gantry crane located at the top of the workshop, then transports the vehicle-mounted gas cylinder to directly above a cleaning tank by using the gantry crane, and then vertically immerses the hoisted vehicle-mounted gas cylinder into the cleaning liquid in the cleaning tank. After immersion, the cleaning liquid in the cleaning tank flows into the vehicle-mounted gas cylinder from the upper and lower ports of the vehicle-mounted gas cylinder, and the cleaning liquid cleans the oil stains attached to the inner wall of the vehicle-mounted gas cylinder. After a period of cleaning, the cleaned vehicle-mounted gas cylinder is hoisted out of the cleaning tank by using the gantry crane, and after being hoisted out, the worker takes the vehicle-mounted gas cylinder off the gantry crane. After being taken off, the worker puts the vehicle-mounted gas cylinder into a drying tunnel, and dries the cleaning liquid on the inner wall of the vehicle-mounted gas cylinder by using the heat in the drying tunnel. The above operation is repeatedly performed multiple times, so that multiple vehicle-mounted gas cylinders can be continuously cleaned.

[0004] However, the method in the workshop can clean the vehicle-mounted gas cylinder formed by stretching, but still has the following technical defects in technology:

[0005] I. Before cleaning, the vehicle-mounted gas cylinder needs to be manually bound by using the hoisting rope of the gantry crane, and then the vehicle-mounted gas cylinder to be cleaned can be hoisted. After cleaning, the hoisting rope needs to be manually untied, which undoubtedly increases the cleaning time of a single vehicle-mounted gas cylinder, and thus reduces the cleaning efficiency of the vehicle-mounted gas cylinder.

[0006] II. After the vehicle-mounted gas cylinder is cleaned, the cleaned vehicle-mounted gas cylinder needs to be manually put into a drying tunnel for drying, and the intermediate turnover process consumes a large amount of time, thus reducing the cleaning efficiency of the subsequent vehicle-mounted gas cylinder.

[0007] III. After the vehicle-mounted gas cylinder is cleaned by the cleaning tank, the workers find that the oil stains are still attached to the arc-shaped surface 1 located in the mouth of the vehicle-mounted gas cylinder, and thus there is the technical defect of incomplete cleaning. Therefore, the vehicle-mounted gas cylinder can only be cleaned multiple times, which undoubtedly increases the cleaning time and reduces the cleaning efficiency of the vehicle-mounted gas cylinder.

[0008] Therefore, there is an urgent need for a cleaning line and method that can greatly improve the cleaning efficiency of vehicle-mounted gas cylinders and thoroughly clean away the oil stains adhering to the curved surface of the vehicle-mounted gas cylinders. Summary of the Invention

S92, control the output shaft (12) of self locking hydraulic motor (11) to rotate counterclockwise, the output shaft (12) drives the rotating plate (13) to rotate counterclockwise, the rotating plate (13) drives the fixed plate (14) to rotate synchronously, the fixed plate (14) drives the mounting plate (17) to rotate counterclockwise synchronously through the main shaft (16), when the output shaft (12) rotates 90°, the controller controls the self locking hydraulic motor (11) to close, at this time, the vehicle gas cylinder (45) after drying is just in the horizontal state; S93, control the servo motor (36) to continue starting, the servo motor (36) drives the screw rod (35) to rotate, the nut (34) continues to move right along the screw rod (35), the nut (34) drives the clamping cylinder (9) to move right, the clamping cylinder (9) drives the cleaning assembly (10) to move right, the cleaning assembly (10) drives the vehicle gas cylinder (45) to move right, when the vehicle gas cylinder (45) moves to the directly above of the discharge conveyor roller (5), the controller controls the servo motor (36) to close; S94, control the piston rod of the clamping oil cylinder (9) to stretch downward, the piston rod drives the cleaning assembly (10) to move downward, the two limiting seats (21) of the cleaning assembly (10) move downward, the limiting seat (21) drives the vehicle-mounted gas cylinder (45) to move downward, when the vehicle-mounted gas cylinder (45) contacts with the roller of the discharge conveying roller (5), the two piston rods of the double-acting oil cylinder (18) stretch out at the same time, the two piston rods drive the connecting plates (19) connected with them to move in opposite directions, the two connecting plates (19) drive the clamping rods (20) connected with them to move in opposite directions, the two clamping rods (20) drive the limiting seats (21) connected with them to move in opposite directions, at this time, the two limiting seats (21) are separated from the two bottle mouths of the vehicle-mounted gas cylinder (45); S95, after the limiting seat (21) is separated from the vehicle-mounted gas cylinder (45), the piston rod of the clamping oil cylinder (9) is controlled to retract upward, the piston rod drives the cleaning assembly (10) to move upward, the cleaning assembly (10) moves away from the vehicle-mounted gas cylinder (45); then control the discharge conveying roller (5) to start, the roller of the discharge conveying roller (5) drives the dried vehicle-mounted gas cylinder (45) to convey to the right, so as to convey the dried vehicle-mounted gas cylinder (45) to the designated area; S100, repeat the operation of steps S1-S9, so that the cleaning and drying treatment of multiple vehicle-mounted gas cylinders (45) can be realized continuously.
