Description

Split type pay off rack

Technical Field

The utility model belongs to the technical field of the coiling of metal wire, area in the operation transportation, concretely relates to detachable pay off rack.

Background

After the steel bars are manufactured and molded, in order to facilitate transportation and subsequent use, the steel bars are wound into the shape of coiled steel bars (also called steel bar wire coils), stacked on a flat truck through a crane or a forklift, transported to a use site, and then unloaded through the crane or the forklift and stacked according to a standard level; when the steel bar coil is used, an operator usually supports the steel bar coil through a pay-off rack so as to gradually pull out (simultaneously straighten) the steel bars along the end of the steel bar coil for use.

The pay-off stands are various in forms, and are divided into a vertical pay-off stand and a horizontal pay-off stand according to the posture of a steel bar coil in use, the horizontal pay-off stand is divided into a rolling pay-off form and a gun carriage type pulling pay-off form, and the horizontal rolling pay-off can refer to the structure shown in CN204564816U, so that the inconvenience is that after the steel bar coil is sleeved with the coil, the coil is horizontally arranged on the body, the body needs to transversely bear the weight of the coil and the steel bar coil, and the strength requirement is high; the gun carriage type pulling paying-off structure can be seen in CN205393215U, and has the disadvantage that the pulled-out steel bars have torsional deformation and are difficult to straighten or straighten in subsequent use. The vertical pay-off rack is more common, see for example the structure shown in CN205463697U, CN204262087U, CN208712552U, CN207090646U, the steel bar coil and the pay-off rack are coaxial, the load-carrying property of the base is better, the pay-off rack can be rotatably arranged on the base, the process of pulling and paying off the steel bar is more flexible, the steel bar pulled out for use does not have torsional deformation, the inconvenience is that the vertical pay-off rack usually has a higher top height, the process of sleeving the steel bar coil stacked in a horizontal posture onto the vertical pay-off rack from the top end needs to be straightened (vertical) and lifted to a position where the bottom end is higher than the top end of the vertical pay-off rack by using a crane or a forklift, and then the steel bar coil falls down and is sleeved on the vertical pay-off rack. Therefore, certain requirements are put on the height, if a crane is used, the pay-off rack, the reinforcing steel bar wire coil and the part of the crane above the reinforcing steel bar wire coil occupy the space height, and the implementation is limited in some height-limiting places; if a forklift is used, the reinforcing steel wire needs to be coiled and forked, and the pallet fork at least needs to be lifted to be higher than the top end of the pay-off rack, so that the requirement is provided for the specification of the forklift, the weight of the reinforcing steel wire coil is large, and the reinforcing steel wire coil is lifted to a high position along with the pallet fork, so that the potential safety hazard is not small.

The technical document on how to facilitate steel wire feeding is not described in detail, and from the structure of the vertical pay-off stand structure, the pay-off stand is sleeved on a rotating column extending upwards on the base through a pipe column at an axial line position, and the pay-off stand is required to be lifted to be higher than the top end of the rotating column to be sleeved on the rotating column in a rotating mode.
