The utility model is for crossbeam height that can convenient adjusting portal frame, to adapt to the Job Operations under varying environment adjusting, preferably technical scheme is, on one-level montant and secondary montant, be respectively equipped with that several are vertically disposed for adjusting the pin hole of portal frame height, by adjust the height of portal frame with different pin holes.
The utility model, for the ease of dismounting and assembling portal frame, improves the transportation convenience of portal frame, and preferably technical scheme also has, and one-level montant is connected by pin with connection pipe.
The utility model is in order to improve the stability of portal frame, and preferably technical scheme also has, and pedestal is provided with 4 base supports pin.
The utility model, for can convenient hoist article, reduces the manpower consumption of lifting operation, and preferably technical scheme also has, and manpower cucurbit lower end is provided with movable pulley and suspension hook.
The utility model is in order further to improve the convenience that portal frame height regulates, and preferably technical scheme also has, and the middle and upper part of the middle and upper part of one-level montant and secondary montant is respectively equipped with 5 vertically disposed pin holes.
The assembly operation process of the portable portal frame of the utility model is: first fix pedestal and base supports pin, make pedestal maintenance level and stable, then one-level montant is socketed in connection pipe, plug pin; Again secondary montant is socketed on to the upper end of one-level montant, selects suitable pin hole to insert pin; Again three grades of montants and crossbeam are socketed on to secondary montant upper end, select suitable pin hole to insert pin; Finally manpower cucurbit is connected on load-bearing slide mechanism, completes the assembling of portal frame.
Advantage of the present utility model with beneficial effect is: the portable portal frame of the utility model adopts socket to be connected montant with the combination connecting mode of bearing pin, is convenient to efficient rapid-assembling and dismounting portal frame, is convenient to transport portal frame; The montant of the portable portal frame of the utility model connects the mode that adopts socket to be connected with bearing pin, makes montant have higher mechanical strength and stability, has improved weight capacity and the hoisting capacity of portal frame, has improved the transaction capabilities of portal frame.
