Description

Technical Field

[0001] The utility model relates to the technical field of cement pole production devices, in particular to a fixing device for making an annular concrete pole skeleton. Background Art

[0002] In the past, the processing and manufacturing of electric pole wire cages relied entirely on manual operations, which was not only time-consuming and labor-intensive, but also posed a safety hazard when fixing the longitudinal wires. If the tensioning was done electrically, improper control could easily lead to the breakage of the longitudinal wires.

[0003] In order to solve this technical problem, the prior art provides CN205816652U, an axial steel wire tensioning and positioning device for manufacturing electric pole wire cages. The longitudinal steel wires of the wire cages are tensioned by a motor in a screw-driven manner, which facilitates the tensioning of the longitudinal steel wires of the wire cages. An annular pressure sensor is provided to avoid breaking the longitudinal steel wires.

[0004] However, there are also certain technical problems in its use. For example, when the device is working, the height-adjustable support feet need to be adjusted so that the rollers leave the ground to prevent the frame from moving. When the device needs to be moved, the height-adjustable support feet need to be adjusted so that the rollers touch the ground and the height-adjustable support feet leave the ground. However, in order to ensure the stability of the device during use, the height-adjustable support feet will not be set at only one or two, but multiple. This will require the staff to adjust the height of each height-adjustable support foot separately during use of the device. This will not only make the staff's operation more cumbersome, but also easily cause the device on the frame to tilt when the staff only adjusts one of the height-adjustable support feet. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a fixing device for making an annular concrete pole skeleton, which is not only convenient for workers to operate the device, but also can prevent the device on the frame from tilting during use and causing safety accidents.
