The utility model relates to building technical field especially a cup mouth foundation steel structure column installation horizontal positioning tool, including four resistance positioning mechanism, four resistance positioning mechanisms two two symmetry settings, every resistance positioning mechanism includes clamping mechanism, two fixed plates are fixed on the clamping mechanism symmetry, two fixed plates are common and are equipped with first threaded rod and are screwed, the first threaded rod one end rotates and is equipped with resistance plate, the other end is equipped with first hand wheel fixedly, the utility model discloses when using, utilize four clamping mechanisms and fix on the four around of pouring concrete fence, subsequently utilize the screwing of first threaded rod to promote resistance plate, utilize multiple resistance plates and stop up steel structure column, and then adjust the perpendicularity of steel structure column and adjust, and simple preparation, low cost can be used, in addition, the contact area of multiple resistance plates and steel structure column is big, and simultaneously, the contact area is also enough flat, can ensure the adjustment of steel structure column perpendicularity adjustment.

The utility model belongs to the field of logistics storage and transportation technology, concretely relates to a heavy load shuttle vehicle, device includes two fixed baffle of shuttle vehicle body and setting on two end portions, sets up between two fixed baffle and is located on the rear baffle and front baffle of two end portions of fixed baffle. The front baffle includes two respectively hinged on the end portion of two fixed baffle baffle structure. The utility model through the mode of rotation connection of front baffle and fixed baffle, both guaranteed the tray of carrying goods when entering the shuttle vehicle, the contact surface of tray is even, overcomes the problem of carrying jamming, and at the same time after the tray all enters the shuttle vehicle, the front baffle cooperates with the fixed baffle and constitutes the fixed space of limiting the tray sliding out through the mode of rotation, guarantees the stability of goods when the shuttle vehicle transportation.
