Description

Technical Field

[0001] The invention relates to the technical field of tank body wrapping equipment, in particular to a small-sized binding wrapping machine and a wrapping method. Background Art

[0002] Hydrogen storage tanks are the main capacity carriers for operating hydrogen, and they have high requirements for safety. The external material needs to be additionally wrapped with a steel layer to strengthen the tank's stress adaptation strength to collisions during transportation and reduce the risk of damage and leakage caused by impacts from external objects. In the process of wrapping the outer plate of a small tank, the outer steel layer has a relatively large release of elastic potential energy due to its small diameter, and it is difficult to assemble it after bending it, resulting in greater difficulty in the wrapping operation of the small tank. It is impossible to simultaneously achieve the bending of the steel plate and the assembly of the steel plate and limit the bending rebound of the steel plate. When a bundling wrapping method is used, this inability to synchronize factors causes the steel plate bundling action to need to be actively performed frequently and multiple times, and the joints of the steel plates are prone to margin mismatch and inaccurate positioning due to the inability to limit their diameter margins, making the external wrapping of the steel plates of small tanks particularly difficult.

[0029] The device adopts guided filling for the lateral filling of the lower wrapped plate, and the limiting introduction plate at the end of the adaptive installation group cooperates with the limiting rear plate to guide the edge and position the steel plate so that the steel plate automatically forms a curved arc plate shape in the process of guiding it into the adaptive installation group.

There is no need to perform additional operations such as bending on the steel coil, and less errors are generated.

[0030] This device uses a simple and reliable lateral bundling method to solve the problem of inconvenient bundling and welding of the external steel cladding of small circular steel tanks due to large elastic deformation caused by short length. The shorter steel cladding layer has a larger angular rebound force after bending. When releasing the cable, this device is unlocked synchronously in multiple directions. In addition, it has a cable opening component to limit the surface of the upper steel plate, thereby reducing the problem of rapid rebound of the upper surface steel cladding due to poor welding quality. In addition, after the traction steel cable is stretched, the filled steel cladding always has a positioning and limiting effect on its arc position during the process of guiding the filling and increasing the arc adaptability. At the end of the positioning limit, the synchronized traction steel cable position has also been tightened and bound, so that the newly placed outer steel plate does not have the elastic deformation release conditions and release stroke. The above beneficial effects can make this device have better adaptability when adapting to small bundled steel tank operations. At the same time, the selection toughness range of the external steel cladding can be wider, and it has better adaptability when it is suitable for shorter circular steel layers (smaller circular hydrogen tanks) of the same material.

The limiting introduction plate 234 at the end of the adaptive installation group 202 cooperates with the limiting rear plate 6 to guide the edge, so that the steel plate 7 automatically forms a curved arc plate shape during the process of guiding into the adaptive installation group 202. After the steel plate 7 is completely located in the limited range outside the integral limiting introduction plate 234 and the limiting rear plate 6, the other side of the steel plate 7 is docked with the steel coil integration groove 215 on the movable installation group 201.

[0084] The method utilizes the design of the connecting extension adaptable belt 218 between adjacent steel coil integration grooves 215, and is equipped with a synchronous cable opening and contraction method in all directions, so that after the steel plate 7 cohesion limit of the limit rear plate 6 is released, the circular diameter of the steel plate 7 can be reduced only by manipulating the movable installation group 201, and it can be more convenient to adapt to the outer wall of the hydrogen tank body 5, and can quickly complete the bending process of the next layer of steel plate 7 before the wrapping, welding and positioning process, so that the bending process and the assembly process are realized in a nearly synchronous manner, which can simplify the work process, improve the automation level of the device, and do not need to perform additional operations such as bending on the steel coil, resulting in less errors.

[0085] The device utilizes a simple and reliable lateral bundling method to solve the problem of inconvenient bundling and welding of the outer steel cladding of a small circular steel tank body due to the large elastic deformation caused by the short length. The shorter steel cladding layer has a larger angular rebound force after bending. The device is unlocked synchronously in multiple directions when the cable is released. In addition, a cable opening component 203 is provided to limit the surface of the upper steel plate 7, thereby reducing the problem of rapid rebound of the upper surface steel cladding due to poor welding quality. In addition, after the traction steel cable 107 is stretched, the filled steel cladding always has a positioning restriction effect on its arc position during the process of guiding the filling and increasing the arc adaptability. At the end of the positioning restriction, the synchronous traction steel cable 107 position has also been tightened and bound, so that the newly placed outer steel plate 7 does not have the elastic deformation release conditions and release stroke. The above beneficial effects can make the device have better adaptability when adapting to the operation of bundling small steel tanks. At the same time, the material toughness range of the external steel cladding can be wider, and it has better adaptability when it is suitable for a shorter circular steel layer (a smaller circular hydrogen tank body 5) of the same material.
