Referring to fig. 1 and 2, a simple portal frame comprises a beam 6, an upper column 3 and a lower column 2, wherein the upper column 3 is in a door-shaped structure, the beam 6 is detachably arranged at the top of the upper column 3, a longitudinal opening 4 is formed in the upper part of the lower column 2, the width of the longitudinal opening 4 is equal to that of a supporting leg of the upper column 3, a plurality of slots 201 penetrating through the longitudinal opening 4 are formed in the lower column 2 from top to bottom, inserting holes corresponding to the slots 201 are formed in the supporting leg of the upper column 3, inserting pins 5 corresponding to the slots 201 are formed in the supporting leg of the lower column 2, and the number of the supporting legs of the upper column 3 is equal to that of the lower column 2; still be equipped with base 1 simultaneously, it is same be equipped with two lower stands 2 on the base 1, and the distance between two lower stands 2 equals with the distance between two landing legs of last stand 3.

Specifically, crossbeam 6, upper column 3 and lower column 2 are the main part of this embodiment, and wherein, lower column 2 is used for supporting upper column 3, and upper column 3 is used for supporting crossbeam 6, sets up lifting device such as electric block, chain block on crossbeam 6 afterwards.

In order to increase the stability of the whole device, the upper upright 3 is arranged in a door-shaped structure, that is, the upper upright 3 comprises a cross bar and two legs, and correspondingly, one upper upright 3 corresponds to two lower uprights 2. In the present embodiment, in order to increase the stability of the upper column 3, a reinforcing rib is provided on the upper column 3.

For the lower upright 2, the upper part of the lower upright 2 is provided with a longitudinal opening 4, and the longitudinal opening 4 divides the upper part of the lower upright 2 into a left part and a right part, and for the longitudinal opening 4, the following conditions need to be satisfied: the width of the legs of the upper upright 3 is equal to the width of the longitudinal opening 4, while the legs of the upper upright 3 can be inserted inside the longitudinal opening 4. In order to fix the upper upright post 3 conveniently, a plurality of slots 201 penetrating through the longitudinal opening 4 are further formed in the lower upright post 2, a plurality of jacks are further formed in the supporting legs of the upper upright post 3, the size and the setting mode of the jacks correspond to the slots 201, and meanwhile, the pins 5 are further arranged, and the pins 5 correspond to the slots 201. When the plug is used, the slot 201 corresponds to the jack position, and then the plug 5 is inserted. Theoretically speaking, only one row of slots 201 are arranged in the vertical direction, the upper upright post 3 can be fixed on the lower upright post 2, and therefore the installation is convenient, and meanwhile, the conventional requirements can be met, but in the actual use process, the uppermost pin 5 and the lowermost pin 5 are easy to damage when the weight of goods is slightly larger under the condition that only one row of slots 201 is arranged, and therefore two rows of slots 201 can be arranged in places with larger weight of goods. In the present embodiment, only one row of slots 201 is provided.

In order to reduce the center of gravity of the whole portal frame, the portal frame is further provided with a plurality of bases 1, each base 1 is provided with two lower upright posts 2, and the distance between the two lower upright posts 2 is equal to the distance between the two support legs of the upper upright post 3. For the base 1, it has certain weight, can show the focus that reduces whole portal frame, simultaneously, locates two lower posts 2 on same base 1, can strengthen the stability of system. In some embodiments, in order to enhance the moving performance of the whole portal frame, a plurality of overweight universal wheels 7 are also arranged on the base 1, and the overweight universal wheels 7 are provided with brakes as can be understood by those skilled in the art.

There are many methods for detachably arranging the cross beam 6 on the top of the upper upright 3, for example, a plurality of threaded holes are arranged on the cross beam 6, and the top of the corresponding upper upright 3 is also provided with threaded holes and then fixed by fastening through bolts and nuts; however, in consideration of the load-bearing performance of the cross member 6 and the ease of removal and installation, the present embodiment proposes a new detachable reinforcement member.

Referring to fig. 3, the reinforcing member is arranged at the top of the upper column 3, and includes a reinforcing plate 8, the reinforcing plate 8 is fixedly arranged at the top of the upper column 3, meanwhile, a vertical plate 801 is arranged on each of the left and right sides of the reinforcing plate 8, a vertical chute is arranged on the vertical plate 801, and a horizontal sliding plate 803 is also arranged, and two ends of the horizontal sliding plate 803 are arranged inside the vertical chutes, so that the horizontal sliding plate 803 can slide along the vertical chutes; be provided with the first through-hole of several at crossbeam 6 both ends, set up the second through-hole of several on horizontal sliding plate 803, and the size of first through-hole and the size phase-match of second through-hole are provided with the screw hole simultaneously on gusset plate 8 to be provided with this screw hole assorted fastening bolt 802. In use, the fastening bolts 802 pass through the first and second through holes and engage with the threaded holes, thereby securing the cross member 6 within the reinforcement member. Due to the arrangement of the horizontal sliding plate 803 and the two vertical plates 801, the tendency of the cross beam 6 to tilt left and right can be reduced to a certain extent. In the present embodiment, the cross beam 6 is an i-beam.

Referring to fig. 4, since the fastening bolt 802 and the plug 5 are provided in the present embodiment, these components are relatively small in size and easily lost, and therefore, in order to facilitate storage, a storage case 103 is provided on the base, and the storage case 103 is divided into two parts, one part for storing the plug 5 and the other part for storing the fastening bolt 802. Meanwhile, as can be seen from the present embodiment, relatively fewer fastening bolts 802 are required, and relatively more bolts 5 are required, so that the portion of the housing case 103 for housing the bolts 5 is relatively large.

Referring to fig. 4, since the beam 6 and the upper column 3 of the present embodiment are detachable, in order to store the detached beam 6 and the detached upper column 3, a first groove 102 and a second groove 101 are provided on the base 1, wherein the first groove 102 is used for placing the upper column 3, and the second groove 101 is used for placing the beam 6. Because the upper upright post 3 is in a door-shaped structure and is provided with two support legs, two first grooves 102 are formed, the distance between the two first grooves 102 is equal to the distance between the two support legs, and meanwhile, the width of each first groove 102 is not less than the width of each support leg of the upper upright post 3, so that the upper upright post 3 can be placed in the first grooves 102; likewise, the width of the second groove 101 is equal to the width of the beam 6, so that the beam 6 can be placed inside the second groove 101.

During the use, according to the height of the article of waiting to lift by crane, adopt bolt 5 equipment not upper standing pillar 3 of co-altitude, adopt fastening bolt 802 to fix crossbeam 6 afterwards, later lift by crane the part through setting up hand block, electric block etc. on crossbeam 6, hoist and mount the back that finishes, at first demolish crossbeam 6, demolish upper standing pillar 3 afterwards, fastening bolt 802 and bolt 5 after demolising set up in receiver 103, upper standing pillar 3 locates in first recess 102, the crossbeam is located in second recess 101.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the embodiments of the present invention are all covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
