Description

Technical Field

[0001] The invention relates to a clamping ring device for tank box rotation operation and an installation operation method. Background Art

[0002] In the production, manufacturing, maintenance and inspection of tank containers, it is often necessary to rotate the tank containers. However, due to the frames and other structures on the outside of the tank body, the rotation of the tank containers is difficult. At the same time, the length, width and height of the tank containers vary greatly, and different devices need to be configured for tank containers of different sizes. It is necessary to solve the rotation problem of the tank containers during operation and solve the flexible operation requirements of the rotation of different tank containers, while meeting the requirements of rapid installation and transportation.

[0003] The existing technology connects the tank container with a rotating ring. The rotating ring has holes at the four corners that can be connected to the end holes of the tank container corner pieces. The rotating ring and the tank container are connected by four T-shaped bolts and fastening nuts to connect the tank container corner pieces and the rotating ring. After the connection is completed, the tank container with the rotating ring is placed on a special roller frame for rotating operation. There are the following disadvantages:

[0004] The rotating ring and the tank container are connected by four fastening bolts and the holes of the corner fittings. Each operation requires the four holes of the rotating ring to be aligned with the mounting holes of the corner fittings at the same time. The rotating ring is large in size and weight, and it is difficult to align the four holes at the same time. After alignment, the four corners need to be tightened, which is time-consuming and affects the rhythm in mass production. When the tank container is rotating, the use of ordinary locking mechanisms is prone to relative sliding between the tank container and the rotating ring, and the stability and safety are poor. The installation of the rotating ring requires lifting operations throughout the entire process, which requires high lifting facilities and takes a long time to occupy the lifting facilities. Due to the high height of the tank container, personnel need to work at a height when tightening the bolts, which is not safe and convenient. The existing rotating ring cannot take into account tank containers of different heights and widths, and has poor compatibility. In the case of small batches and multiple varieties of tank containers, a large number of rotating rings are required. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a clamping ring device and an installation method for tank container rotation operations to solve the above problems in the prior art.

[0008] The rotating ring comprises a circular ring, a square frame, a lower connecting plate, an upper connecting plate, a fixing hook, a width adjustment plate, a width stopper, a height adjustment block, and a lifting ring; the circular ring is fixed to one side of the frame, two upper connecting plates located at the top and two lower connecting plates located at the bottom are fixed at the four corners of the frame, the width adjustment plate and the width stopper connected thereto are arranged on the upper connecting plate, and mounting holes are arranged on the lower connecting plate, and the mounting holes on the two lower connecting plates can be respectively aligned with the through holes on the two bottom corner pieces of the tank container; the fixing hook is arranged on the upper crossbeam of the frame through the height adjustment block and the fixing hook is oriented downward, and a lifting ring is also fixed on the upper crossbeam of the frame;

[0009] The locking mechanism includes a locking head, a fixing block and a fastening nut; the locking head and the fastening nut can fasten the tank corner piece, the lower connecting plate and the fixing block;

[0010] The roller frame can cooperate with the circular ring of the rotating ring to perform a rotating operation.

[0011] The present invention also includes the following technical features:

[0012] Specifically, the height adjustment block is provided with a plurality of connection holes at different heights so that the fixing hooks can be installed at different heights to correspond to tank containers of different heights.

[0013] Specifically, the width adjustment plate is provided with a plurality of connection holes arranged in sequence along the horizontal direction so as to adjust the horizontal installation position of the width stopper; the width adjustment plates and the width stops on the two upper connecting plates are arranged symmetrically on the left and right; the two width stops can limit the left and right positions of the tank container and can adapt to tank containers of different widths.

[0014] Specifically, there are two lifting rings which are symmetrically arranged on the left and right sides along the center of the upper crossbeam of the frame and are used for lifting and installing the rotating ring.

[0015] Specifically, there are multiple mounting holes on the lower connecting plate and the mounting holes are arranged at different heights for mounting the fastening mechanism to correspond to tank boxes of different heights.

[0016] Specifically, the cross section of the lock head is T-shaped; the fixing block has a central through hole, and the edge of one end of the fixing block is a limiting boss.

[0017] Specifically, the fixing block can pass through the mounting hole on the lower connecting plate and the through hole on the bottom angle piece of the tank box in sequence, and the limiting boss of the fixing block is limited on the side of the lower connecting plate; the rod end of the locking head enters from the side of the bottom angle piece of the tank box and extends out of the central through hole of the fixing block and is installed in cooperation with the fastening bolt, and the head end of the locking head is limited on the side of the bottom angle piece of the tank box.

[0018] Specifically, a limiting groove is provided on the end face of the other end of the fixing block, which is perpendicular to the length direction of the fixing block, and the width of the limiting groove is similar to the width of the head end of the lock; the lock head can be limited in the limiting groove after being inserted into the through hole of the angle piece with the fixing block and rotated 90°, and the lock head presses the bottom angle piece, the fixing block, and the lower connecting plate of the rotating ring, and the lock head cannot rotate in the direction.

[0019] The method for installing the clamping ring device for tank container rotation operation comprises the following steps:

[0020] Installation of rotating ring: When in use, the rotating ring is hoisted on the upper end surface of the tank container, close to the end frame of the tank container, and after it falls, the fixed hook is hung on the upper end beam of the end frame of the tank container or the top hoisting hole of the top corner piece. The rotating ring falls naturally. At this time, the fixed hook provides a positioning reference for the entire rotating ring, and the width block of the rotating ring provides lateral positioning. The mounting hole on the lower connecting plate of the rotating ring and the through hole of the bottom corner piece of the tank container are quickly positioned; after the hoisting is completed, the locking mechanism is installed. Due to the presence of the fixed hook on the top, the relative movement of the top of the tank container is limited, replacing the locking mechanism on the top. The personnel only need to install the locking mechanism at the bottom to complete the fixing of the entire rotating ring;

[0021] Installation process of locking mechanism: the lock head and the fixing block pass through the installation hole of the lower connecting plate and the through hole of the bottom angle piece in sequence, the lock head is rotated 90°, the lock head falls into the limit groove, the fastening nut is installed and fastened, at this time the angle piece and the lower connecting plate are fastened by the lock head and the fastening nut, the installation of the four locking mechanisms of the bottom angle pieces of the front and rear ends of the tank container and the two sets of clamping ring devices is completed in sequence, and the installation of the rotating ring is completed;

[0022] After installation is completed, use a container spreader or bottom transfer vehicle to move the tank container to the roller frame and rotate it to complete the entire operation.

[0023] Specifically, for tank containers of different heights or widths, the clamping ring device is adaptively adjusted, including the following steps:

[0024] Height and width adjustment: When encountering tank containers of different heights, adjust the connection hole position of the fixing hook and the height adjustment plate, and at the same time change the mounting hole of the locking mechanism; for tank containers of different widths, adjust the connection hole position of the width stopper and the width adjustment plate to adapt to different tank containers.

[0025] Compared with the prior art, the present invention has the following technical effects:

[0026] The connection method of the rotating ring and the tank box in the present invention is a combination of two connection methods: the top uses a fixed hook to hang the upper end beam or the corner piece hole, and the bottom uses a lock to fasten, which reduces 50% of the bolt fastening operations. At the same time, after the fixed hook is hung on the upper end beam of the tank box or the top corner piece lifting hole, an operation fulcrum is provided. The lifting process no longer needs to occupy the overhead crane or lifting facilities throughout the entire process. At the same time, an installation positioning reference is provided for the installation of the rotating ring, and the bottom lock is positioned with the corner piece to achieve quick installation.

[0027] The fixing block in the lock of the present invention is close in size to the angle piece hole, which reduces the slippage between the fastener and the angle piece hole during the rotation process. The slippage is reduced from tens of millimeters to 1-3 mm compared to ordinary bolt connections, thereby improving safety and stability.

[0028] The present invention adopts a method of hanging the upper end beam with a fixed hook to avoid interference problems when lifting with a container spreader. At the same time, compatibility is achieved by adjusting the installation position of the fixed hook for different tank containers. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The roller frame 1 can cooperate with the circular ring 21 of the rotating ring 2 to perform a rotating operation.

[0044] The height adjustment block 29 is provided with a plurality of connection holes at different heights so that the fixing hook 28 can be installed at different heights to correspond to tanks 4 of different heights. The height that the rotating ring 2 can adapt to can be adjusted by adjusting the installation positions of the fixing hook 28 and the height adjustment block 29 according to the different heights of the tanks 4. The fixing hook 28 has the following main functions: first, it can limit the rotating ring 2 and fix the relative position of the rotating ring 2 and the tank 4; second, it can quickly align the installation hole of the lower connecting plate 23 at the bottom of the rotating ring 2 with the installation hole of the bottom corner piece of the tank 4 to reduce the assistance of personnel; third, it can replace the top locking mechanism 3 to reduce the number of locking mechanisms 3 installed between the rotating ring 2 and the tank 4.

[0047] There are multiple mounting holes on the lower connecting plate 23 and they are arranged at different heights for mounting fastening mechanisms to correspond to tank boxes 4 of different heights.

[0048] The cross section of the lock head 31 is T-shaped; the fixing block 32 has a central through hole, and the edge of one end of the fixing block 32 is a limiting boss that serves as a limiting and padding plate.

[0049] The fixing block 32 can pass through the mounting hole on the lower connecting plate 23 and the through hole on the bottom corner piece of the tank box 4 in sequence, and the limiting boss of the fixing block 32 is limited on the side of the lower connecting plate 23; the rod end of the locking head 31 enters from the side of the bottom corner piece of the tank box 4 and extends out of the central through hole of the fixing block 32 and is installed in cooperation with the fastening bolts, and the head end of the locking head 31 is limited on the side of the bottom corner piece of the tank box 4.
