Detailed Description

The first embodiment.

This embodiment provides fork truck's alternative, can realize fork truck effect when carrying the metal embryo, still has the effect that fork truck does not have.

It should be determined that the side of the present embodiment having the pincer-like extension 3 is a front side, and the other side opposite to the pincer-like extension 3 is a back side. The use flow and the structural principle of the embodiment are as follows:

first, charging process

1. Rotating the base 1 to make the back face opposite to the transport vehicle for the metal blank; 2. conveying the metal blank on the transport vehicle to the lifting platform 4 by using a forklift; 3. starting the lifting mechanism 5 to drive the lifting platform 4 which is already arranged on the metal blank to lift, so that the unloaded lifting platform 4 is lifted to a proper height; 4. then, a forklift is used for conveying the metal blank on the transport vehicle to the idle-load lifting platform 4;

second, unloading process

1. Pushing the base 1 or the longitudinal beam 2 to convey the metal blank to a machining center; 2. rotating the base 1 to enable the front surface to face the machining center and be tightly attached; 3. when the base 1 and/or the longitudinal beam 2 are tightly attached to the machining center, the supporting plate 6 of the pincerlike extension part 3 extends into the machining center to be in contact with the workbench and is level with the workbench; 4. starting the lifting mechanism 5 to drive the lifting platform 4 to be unloaded to move to the same height as the supporting plate 6; 5. pushing the metal blank on the lifting platform 4 down from the lifting platform, and finally conveying the metal blank to a workbench through a supporting plate 6; 6. pushing the base 1 to go to other machining centers for continuous discharging.

In the present embodiment, the pallet 6 of the pincer-like extension 3 is set to be at the same height as the machining table according to the height of the machining center table, the pallet 6 is fixed to the side beam 2, and the closer the side beam 2 is to the machining center, the closer the pallet 6 is to the machining table until the pallet 6 abuts on the edge of the machining table. The metal blank on the lifting platform 4 is pushed to slide to the supporting plate 6, and then slides to the workbench by the supporting plate 6, so that the feeding is completed.

The lifting mechanism 5 can adopt any feasible product, but needs to meet the following requirements, one is that the lifting stroke meets the requirement that any layer in the multi-layer lifting platform 4 is lifted and lowered to the height of the pincerlike extension part 3, and the other is that when materials are stored, the lifting mechanism can stably hover on a certain specified height of the lifting platform 4 for a long time, so that the basic requirement of storing the materials for a long time is met. In the present embodiment and all other embodiments, the number of the lifting mechanisms 5 is not limited, but preferably, at least one lifting mechanism 5, i.e., at least two lifting mechanisms 5, are respectively disposed on both sides of the base 1, and each lifting mechanism 5 is disposed in the middle of the longitudinal beam 2, so as to ensure that the lifting mechanism 5 applies a force to the lifting platform 4 to stably lift the lifting platform 4.

Lift platform 4's balladeur train 8 and slide in spout 7 on longeron 2, elevating system 5 can be connected with balladeur train 8, theoretically every lift platform 4 can be equipped with independent elevating system 5, but for simplifying the structure raise the efficiency, pass through the frame with a plurality of balladeur train 8 of lifting platform 4 and link together, make a plurality of platforms 4 go up and down simultaneously, can only need an elevating system 5 to control all platforms 4 that lift this moment, even provide more than one elevating system 5 as required and provide the lift, also can compress required elevating system 5's quantity as far as possible. It should be noted that although a forklift can be substituted for the blank transportation, the forklift is still used to fork the blank from the transportation vehicle and transport the blank to the lifting platform 4. The practical significance that this embodiment exists is just replacing fork truck and improving the practicality of whole material and carrying slow link. The adaptation degree with a machining center is increased, under the guidance of the significance of the utility model, no manpower is allowed to be used in the conveying process of the blank from a forklift to the lifting platform 4, so that the blank on the fork frame can be transferred to the lifting platform 4 without obstacles, the lifting platform 4 is provided with an opening 9, the pincerlike extension part 3 is arranged on the longitudinal beam 2 on one side of the front face of the lifting platform 4, the forklift needs to avoid the pincerlike extension part 3 during conveying, and therefore the opening 9 is arranged on the back face of the lifting platform 4. After the forks of the forklift are inserted into the opening 9, the forks are controlled to descend, leaving the blank on the lifting platform 4. In order to make the lifting action of the lifting platform 4 smoother, a pulley can be arranged on the sliding frame 8, and the sliding frame 8 can slide in the sliding groove 7 through the pulley.

The pincer-like extension 3 consists of two support plates 6, the two support plates 6 forming a pincer-like shape. Although the supporting plates 6 are fixed on the longitudinal beam 2, the supporting plates have the function of a bridge for conveying materials to the workbench, if the distance between the two supporting plates 6 is as wide as the lifting platform 4, the materials cannot be supported, so the distance between the supporting plates 6 must be reduced, the distance is smaller than the edge length or width of the lifting platform 4, the two supporting plates 6 must be symmetrically arranged, and the distance between the two supporting plates 6 and the central axis of the lifting platform 4 is equal. This is so that the pallet 6 needs to extend to the opposite inner side,

the carriage 8 may take any shape, any structure, but more preferably takes a T-shape or a T-shape. The tail 11 of the t-shaped sliding frame 8 is connected with the lifting platform, and the head 10 is branched towards two sides, so that the sliding frame 8 can slide in the front and rear sliding grooves 7 on the same side, for example, the right side of the lifting platform 4 is provided with a front longitudinal beam 2 and a rear longitudinal beam 2, and the sliding frame 8 can slide in the sliding grooves 7 of the two longitudinal beams 2 on the right side.

In this embodiment, there may be three or three lifting platforms 4, in order to reduce the burden of the lifting mechanism 5, the lifting platforms 4 may be divided into two groups, i.e., the first and second lifting platforms (or the bottommost lifting platform 4 and the lifting platform 4 located in the middle) are used as the lower group, the lifting mechanism 5 controls the lifting, the third lifting platform 4 is used as the upper group, the other lifting mechanism 5 controls the lifting, and the lifting mechanism 5 controlling the third lifting platform may be fixed to the top end of the longitudinal beam 2 through the frame.

Example two.

The present embodiment optimizes the structure of the carriage 8, and in the present embodiment, the carriage 8 adopts an H-shaped structure instead of a t-shaped structure, and the H-shaped structure has an advantage over the t-shaped structure in that the length of the H-shaped structure in the longitudinal direction is longer than that of the t-shaped structure in the longitudinal direction, and the longer the longitudinal length of the carriage 8 is, the easier the lifting platform 4 is to maintain in a horizontal state. But also can be better adaptation multilayer lift platform 4 scheme to two-layer lift platform 4 is taken as an example, and the balladeur train 8 of upper strata and lower floor can end to end, further increases the length of balladeur train 8 on vertical, makes and lifts platform 4 stability better. At the same time, in order to reduce the friction, the carriage 8 of H-shaped structure can still be provided with a pulley and slide in the chute 7 through the pulley.
