Embodiment Construction

[0021] First follow figure 1 and Figure 4 The structure of the tower frame shown is installed on the site. The front brace 10 and the rear brace 11 of the tower frame are assembled first, then the left and right beams 12 on the upper side and the left and right beams 13 on the lower side are installed, and finally the driver’s cab support beam is installed. Ladder 1 and platform 2 are not installed first, so as not to be damaged during hoisting and straightening. Then use two wire ropes 4 to connect the lifting lug 3 on one side respectively, and then the other ends of the two wire ropes 4 are connected together with a shackle 7 . Use another wire rope 8 to be respectively fixed on the lower side both sides of the tower, and a movable shackle 9 is installed on the wire rope again, and the door machine automatically selects the lifting point when catching the shackle 9.

[0022] Such as Figure 5 As shown, the hook of the first door machine 5 is hooked on the shackle 7, the...

Abstract

The invention discloses a tower frame assembling and lifting process which is characterized in that a tower frame is directly mounted on a field; and meanwhile, the top end of the tower frame is provided with a lifting lug for lifting, the mounted tower frame is lifted and corrected through matching two portal cranes, and the tower frame is finally mounted and fixed. With the adoption of the manner, the installation of the tower frame becomes simple and safe; and redundant working frames are not needed so that the manpower and the cost are saved and the working efficiency is improved.

Description

technical field [0001] The invention relates to a process for assembling and hoisting a tower frame. The tower frame is firstly assembled on the site, and then installed with a door crane in cooperation with righting. Background technique [0002] When installing the ship loader, the installation of the tower support is very important. The tower support is the skeleton of the ship loader. Whether the ship loader can operate safely has a lot to do with the installation process and strength of the tower support. The tower of the ship loader mainly includes four large parts: the front brace of the mast, the back brace of the mast, the left and right side beams of the mast and the support beam of the driver's cab. The traditional tower installation is to directly lift each part of the tower to the ship through the portal crane. Specify the location, and proceed directly to the installation soldering. Such a method is troublesome to operate because the tower parts are bulky and...
