Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to a tensioning jack hoisting device. Background Art

[0002] After the cast-in-place box girder concrete reaches the specified strength, it is necessary to use jacks to tension the prestressed steel bars. The strength of the steel strands in the anchors is increased through work to give the prestressing value. A lifting device is required when installing the heavy tensioning jacks. The lifting device is also called a gantry crane, platform crane, etc. The lifting device can facilitate the subsequent installation of the tensioning jacks.

[0003] When installing the tension jack, a tension jack lifting device is needed to facilitate the installation of the tension jack. The "tension jack lifting device" disclosed in the application number "CN220149044U" has many disadvantages of low efficiency and the manual hoist generally used to install the jack at the construction site.

[0004] However, there are still many defects in the actual use of lifting devices with similar structures. For example, it does not have the function of improving the installation position accuracy of the tensioning jack. The device is easily affected by external impact, which may cause the tensioning jack to fall off the installation position, thereby causing errors in the construction data, reducing the stability of the installation tensioning jack using the device. At the same time, it does not have the function of automatic maintenance of the device. After long-term use, the lubricating oil of the device is completely consumed, resulting in jamming and abnormal noise of the lifting tensioning jack, shortening the service life of the device. Therefore, it is necessary to design a tensioning jack lifting device. Utility Model Content
