Description

Tower crane jib loading boom pull rod support device

Technical Field

The utility model belongs to the building field, concretely relates to tower crane jib loading boom pull rod holds support device.

Background

After the tower crane is used for a long time, most of equipment has the phenomenon that a cargo boom pull rod supports and cannot be normally used: when the crane boom is disassembled, if the pull rod support cannot be in a working state due to corrosion or loss, the installation and disassembly personnel need to go up to the crane boom to fix the pull rod by using iron wires, so that the working danger of the installation and disassembly personnel is increased; if the pull rod support cannot be retracted into the crane boom during loading and transportation, the transportation vehicle cannot be fully used, and therefore a vehicle needs to be added for transportation.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model discloses a tower crane boom pull rod supporting device, a ferrule is matched with a boom by utilizing a groove, a bolt is replaced, and the situation that the supporting device is rusted and fails is avoided; the operation is easy, and the working state and the non-working state are easily changed.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the pull rod supporting device for the crane boom of the tower crane comprises a crane boom and a ferrule, wherein the ferrule is sleeved on the crane boom, an upper fixing piece is arranged above the outer circumference of the crane boom, a positioning hole is formed in the left side of the upper fixing piece and used for inserting a cotter pin, a stop block is arranged at the right end of the upper fixing piece, a lower fixing piece is arranged below the outer circumference of the crane boom, the ferrule comprises an annular part and a supporting part, an upper groove is formed in the upper portion of the inner side of the annular part, a lower groove is formed in the lower portion of the inner side of the annular part, the upper fixing piece is inserted into the upper groove, and the lower fixing piece is inserted into the lower groove.

Further, the left end of the upper fixing piece is provided with an upper slope facilitating installation of the ferrule.

Further, the left end of the lower fixing piece is provided with a lower slope facilitating installation of the ferrule.

Further, the inner diameter of the ferrule is larger than the outer diameter of the boom.

Compared with the prior art, the beneficial effects of the utility model reside in that:

the ferrule of the supporting bracket device is matched with the upper fixing piece and the lower fixing piece of the crane boom by utilizing the groove, so that bolts are replaced, and the situation that the supporting bracket device is rusted and fails is avoided; easy to operate, when loading and transporting, pull out the split pin on the locating hole, with lasso from last mounting and lower mounting translation, with the lasso rotatory 180 fixed again to last mounting and lower mounting on, light transform work and non-work two kinds of states.
