Description

Tower crane big arm pull rod installation appurtenance Technical Field The utility model belongs to the technical field of tower crane installation, and particularly relates to an auxiliary tool for installing a large-arm pull rod of a tower crane. Background Tower crane is called tower crane for short, also called tower crane, originated from western europe. And the movable arm is arranged on the rotary crane at the upper part of the high-rise tower body. The working space is large, and the device is mainly used for vertical and horizontal conveying of materials and installation of building components in house building construction. When the tower crane is installed, particularly the big arm is installed, the trolley cannot be used when a pull rod (a pull rod pin shaft is installed), so that an installer needs to walk on the big arm of the tower crane, the pin shaft is installed at the position of the pull rod, the tower body passes to the installation position of the pull rod, the potential safety hazard is extremely high, and a plurality of installers drop from the big arm when the installment is carried out. Therefore, we propose a tower crane big arm pull rod installation appurtenance. Disclosure of utility model In order to solve the problems in the prior art, the utility model provides an auxiliary tool for installing a large-arm pull rod of a tower crane, which has the advantage of ensuring the passing safety of an installer when the installer passes on a large arm to the greatest extent when the tower crane is installed. In order to achieve the purpose, the technical scheme is that the auxiliary tool for installing the large arm pull rod of the tower crane comprises a base, a tower body is detachably arranged at the top end of the base, a lifting arm is detachably arranged at the left top end of the tower body, a fixing frame is clamped at the left top end of the lifting arm, a first fixing column is fixedly arranged at the top end of the fixing frame, a lifting ring is fixedly arranged at the top end of the first fixing column, and a safety cable is arranged in the lifting ring. Preferably, the right bottom end of the fixed frame can be detachably provided with a bolt, the bolt penetrates through the right side of the fixed frame, the upper portion of the bolt is spirally rotated to be provided with a nut, and the bottom end of the nut is attached to the right top end of the fixed frame. Preferably, a second fixing column is fixedly arranged at the top end of the middle of the lifting arm, and a lifting ring is fixedly arranged at the top end of the second fixing column. Preferably, a third fixing column is fixedly arranged at the top end of the right side of the lifting arm, and a lifting ring is fixedly arranged at the top end of the third fixing column. Preferably, the middle part of the outer side of the safety cable penetrates through the top hanging ring of the second fixing column and is detachably connected with the top hanging ring of the third fixing column. Preferably, a balance arm is detachably arranged at the top end of the right side of the tower body. Compared with the prior art, the utility model has the following beneficial effects: 1.
