Detailed Description

The first embodiment.

The embodiment provides a lifting scheme for lifting metal products similar to various rack shapes to a certain height, so that workers can conveniently operate the metal products.

The specific working process is as follows: 1. firstly, whether the bottom of a metal product to be processed (hereinafter referred to as a product to be processed) is flat or not needs to be known, and whether structures such as a bottom reinforcing rib exist or not needs to be determined if the bottom of the metal product to be processed (hereinafter referred to as a product to be processed) is not flat; 2. acquiring the flat space position of the to-be-processed product, which is enough to accommodate the main supporting plate 3 and the auxiliary supporting plate 15; 3. the connecting piece 4 is controlled to stretch, and the relative position between the main supporting plate 3 and the auxiliary supporting plate 15 is changed through the connecting piece 4, so that the relative position between the main supporting plate and the auxiliary supporting plate corresponds to the flat space position at the bottom of the product to be processed; 4. starting the lifting mechanism 2, simultaneously supporting the flat space position of the to-be-processed product by the main supporting plate 3 and the auxiliary supporting plate 15, lifting the to-be-processed product under the driving of the lifting mechanism 2, and stopping the lifting mechanism 2 when the lifting height reaches the working height comfortable for workers; 5. after the worker finishes processing the to-be-processed product, the lifting mechanism 2 is started to bring the to-be-processed product to fall on the ground and blanking is carried out, and after blanking is finished, the relative position of the main supporting plate 15 and the auxiliary supporting plate 15 does not need to be adjusted, and direct feeding can be carried out.

Because the processed metal product is mostly made of iron steel and is less made of non-magnetic materials such as copper and aluminum, for improving the stability of the product to be processed on the main and auxiliary supporting plates 15, the magnet can be arranged on the main and auxiliary supporting plates 15 and used for adsorbing the product to be processed.

The distance between the auxiliary supporting plate 15 and the main supporting plate 3 can be adjusted in a telescopic manner by the connecting piece 4, and the telescopic manner can be realized by adopting any feasible existing scheme, for example, a bracket is installed at the bottom of the main supporting plate 3, an electric sliding rail is arranged on the bracket, the auxiliary supporting plate 15 is driven by the electric sliding rail to slide, and the like. But the scheme of the bionic arm or the telescopic link is preferably adopted, the bionic arm refers to a plurality of sections of connecting rods 5 which are hinged with each other, the connecting rods 5 can be fixed by threaded fasteners after the swinging is finished, and the connecting rods 5 and the main and auxiliary supporting plates 15 can also be fixed by the threaded fasteners. The telescopic rod solution is more abundant in the market than the connecting rod 5, which is both from a threaded fixture.

It should be noted that the connecting rods 5 are also in hinged fit with each other, which is similar to the structure of a mechanical arm, so that the swing range of the auxiliary support plate 15 is large, while the telescopic rod is generally formed by sleeving a large-sized tube into a small-sized tube, and the two tubes are in sliding connection or threaded connection with each other without adopting a hinged connection mode, so that the swing range of the auxiliary support plate 15 is small when the connecting piece 4 adopts a telescopic rod scheme.

The lifting mechanism 2 may alternatively comprise any lifting solution including a hydraulic cylinder, but more preferably a hydraulic cylinder, in particular a multi-section hydraulic cylinder, is used, which enables a higher lifting stroke at a lower height. If elevating system 2 adopts the pneumatic cylinder, then can set up safety cover 6 on base 1, safety cover 6 plays support, crashproof, effect such as dustproof with pneumatic cylinder the latter half parcel.

Example two.

The present embodiment is made on the basis of the first embodiment, and provides a scheme of efficient multi-station simultaneous cooperation, which refers to lifting a plurality of to-be-processed articles simultaneously, and performing surface treatment on the lifted to-be-processed articles simultaneously by one operation.

In the present embodiment, the secondary pallet 15 has at least two, and the secondary pallet 15 is no longer in the role of assisting the presence of the primary pallet 3 in the first embodiment, but is the same as the primary pallet 3, and is used to lift the workpiece to be processed individually. Therefore, in the present embodiment, the secondary pallet 15 is connected to the primary pallet 3 in the same relationship with the tree branches and trunks, but the secondary pallet 15 itself has no active lifting power and thus can only be used as the secondary pallet 15.

As shown in fig. 6, the present embodiment is shown to perform two different operations in the same form, the first operation is to deal with a large-scale rack structure having a larger size and weight than the workpiece to be processed shown in fig. 1 and 2 of the first embodiment, and when handling such a large-scale product in the past, a worker needs to spend a longer time to squat under the rack structure due to the large size. However, in this embodiment, at least two auxiliary support plates 15 and one main support plate 3 lift one rack at the same time, so that the stability after lifting is improved, the friction force is increased, and the displacement stroke of the to-be-processed product in the processing process can be well reduced due to the fact that the magnets are still installed and the to-be-processed product is adsorbed. However, in the present embodiment, the plurality of sub-pallets 15 participate in the lifting, and it is difficult to bear the weight of the large gantry to fix the posture by only using the telescopic rod or the screw fixing member of the connecting rod 5 itself.

By above-mentioned purpose and provide a support frame scheme, specifically set up the telescope tube 8 that is used for support column connecting piece 4 on protecting shield 6, set up support sleeve 7 at connecting piece 4 itself simultaneously, after connecting piece 4 is flexible finishes, rotate support sleeve 7 and make its orientation telescope tube 8's direction, rotate telescope tube 8 again and aim at support sleeve 7 and stretch out, telescope tube 8 inserts in support sleeve 7 and fixes, after the completion operation, connecting piece 4 obtains the support, 15 job stabilization nature of auxiliary splint improve greatly.

Example three.

The present embodiment is made on the basis of the second embodiment, since the second embodiment shows a supporting frame solution, and if the pull rod 9 which is convenient for pushing and pulling needs to be arranged on the base 1, all structures of the supporting frame solution need to be avoided, and enough space is left for all structures to swing along with the extension and retraction of the connecting piece 4, so that the pull rod 9 cannot be arranged on the top of the most conceivable edge of the base 1, and since a worker needs to work around the base 1, even stepping on the base 1, the pull rod 9 cannot be fixed and erected on the base 1, otherwise inconvenience is caused to the worker.

Based on the above understanding, the present embodiment provides a retractable pulling rod 9, which is pulled out from the sliding groove 10 when it is needed, and pushed into the sliding groove 10 to be retracted when it is not needed. The chute 10 can be opened on any side of the base 1, as shown in fig. 7 to 11, especially fig. 8, an inclined opening 13 is opened at the top of the chute 10 at the opening, and a limiting measure, i.e., a limiting block, for limiting the separation of the pull rod 9 is provided at the opening at the bottom of the chute 10. One end of the pull rod 9 can be designed into a thicker shape, namely can slide in the sliding groove 10 and can be limited in the sliding groove 10 by a limiting measure. After the pull rod 9 extends out of the sliding groove 10, the top of the sliding groove 10 is provided with an inclined opening 13, so that the pull rod 9 can swing upwards from the opening of the sliding groove 10 and extend upwards in an inclined manner to be more convenient to use. But more preferably, a sliding block 11 is arranged in the sliding groove 10, and the sliding block 11 is tightly matched with the sliding groove 10, so that better sliding stability is provided, and larger shaking cannot occur; a groove 12 is formed in the sliding block 11, a rotating shaft is arranged in the groove 12, and the pull rod 9 is rotatably connected with the rotating shaft. As shown in fig. 11, the groove 12 is formed at an edge of the slider 11, and is open to the side and the top, so that the pull rod 9 can swing in the groove 12.
