Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

The features and properties of the present invention are described in further detail below with reference to examples.

In an automobile production line, when a vehicle body needs to be transferred between different vehicle body carriers, two traditional modes are adopted, one mode is that a transfer machine and two elevators matched with the transfer machine are used, specifically, one elevator lifts the vehicle body on the vehicle body carrier from the vehicle body carrier at the upstream of the transfer machine, then the vehicle body with the upstream lifted from the vehicle body carrier is transferred to the position above the vehicle body carrier at the downstream of the transfer machine through the transfer machine, and the other elevator at the downstream of the transfer machine is used for receiving the vehicle body on the transfer machine and then is placed on the vehicle body carrier at the downstream of the transfer machine. The second mode is performed by a transfer machine (lifting type transfer machine) having a lifting function, and the working process is as follows: the transfer fork of the transfer machine moves to the upper part of the vehicle body carrier at the upstream part, the transfer machine rises to jack up the vehicle body on the vehicle body carrier at the upstream part, the transfer machine moves the vehicle body to the upper part of the vehicle body carrier at the downstream part, the transfer machine falls to place the vehicle body on the vehicle body carrier at the downstream part, and the transfer fork of the transfer machine returns. Of the above two modes, the first mode is suitable for high-beat production, and the second mode obviously has certain cost advantage due to the fact that a single device is few. However, there is no transfer machine designed for transferring a vehicle body, and many of the conventional transfer machines for transferring a vehicle body focus on the function, and have a structure formed by simply assembling, for example, an original fixed transfer machine directly on a single lifting platform, and thus there are certain disadvantages in terms of cost, structural stability, and the like.

The lifting part comprises a pedestal, a lifting driving device and a lifting body, and the lifting driving device is used for driving the lifting body to lift.

The base frame is used as the foundation of the whole automobile body transfer machine, and particularly adopts a rectangular frame type structure which comprises a fixed cross beam 11 and a fixed longitudinal beam 12, wherein the fixed cross beam 11 and the fixed longitudinal beam 12 are connected end to form the rectangular frame type structure, so that the base frame has certain strength to ensure the reliability of the whole transfer machine. In order to fix the base frame, the fixed cross beam 11 and the fixed longitudinal beam 12 of the base frame are respectively provided with a connecting lug plate 13, and the connecting lug plates 13 are used for penetrating foundation bolts and are connected with a foundation (for example, a concrete block buried underground) of a use place.

Guide columns 14 are respectively arranged on four vertexes of a rectangular frame formed by the fixed cross beam 11 and the fixed longitudinal beam 12, wherein every two guide columns 14 are paired and are connected through a lifting cross beam 15 parallel to the fixed cross beam 11, and therefore a vertical frame with two guide columns and a lifting cross beam is formed. Of course, in other embodiments, a middle guide pillar may be disposed between two ends of the fixed beam 11 according to actual strength requirements, so as to form a two-end guide pillar-middle guide pillar-elevator beam type stand.

Of course, in other embodiments, the column may also be directly used as the guide column, and the assembly between the lifting beam and the guide column may be realized by arranging the sliding sleeves at two sections of the lifting beam and by guiding and matching the sliding sleeves and the column.

The lifting drive is used to drive the lifting body to move up and down on the base frame, specifically, the lifting beam 15 to move up and down on the corresponding guide column. In the embodiment, the lifting driving device specifically uses the motor 17 as a power source, and uses two driving arms 18 correspondingly mounted on the base frame and respectively located below the two lifting beams 15 as output members, where the two driving arms 18 are rotating arms, and the rotation axis is perpendicular to the corresponding lifting beam 15 and can rotate in a vertical plane. In order to ensure the synchronization of the two driving arms 18, in the present embodiment, the two driving arms 18 are installed at two ends of a synchronizing shaft 19, and the synchronizing shaft 19 is installed on the base frame through a shaft seat. Of course, the method for ensuring the synchronization of the two driving arms is not limited to this embodiment, and for example, when the driving devices are provided for the two driving arms, the synchronization of the two driving arms may be ensured by means of electric control or the like. A roller 20 is mounted at the free end of each driving arm 18, and when the driving arm 18 rotates upwards in the vertical plane, the roller 20 can contact with the lower side surface of the corresponding lifting beam, so as to jack the lifting beam, which is equivalent to a cam mechanism formed between the driving arm 18 and the corresponding lifting beam. Because the driving arm 18 rotates and the lifting beam 15 moves up and down linearly, the roller 20 rolls relative to the lifting beam contacting with the roller in the process that the driving arm 18 drives the corresponding lifting beam 15 to move, thereby avoiding the clamping stagnation between the two. In this embodiment, in order to ensure the relative position between the roller 20 and the corresponding lifting beam, a sub-beam 21 is fixedly provided on the lower side surface of the lifting beam 15 at a position corresponding to the roller, and the lower side surface of the lifting beam 15 and the upper side surface of the sub-beam 21 mounted thereon are respectively located at the upper and lower sides of the roller 20.

The output end of the motor 17 is sequentially connected with the speed reducer 22 and the driving chain wheel 23, the driven chain wheel 24 matched with the driving chain wheel 23 is arranged on the synchronizing shaft 19, the driving chain wheel 23 and the driven chain wheel 24 are driven by the transmission chain 25, in operation, the synchronizing shaft 19 is driven to rotate by the motor 17, the driving arm 18 fixedly installed on the synchronizing shaft can further drive the lifting cross beam to ascend and descend, the descending of the lifting cross beam 15 can also be completed under the action of gravity, and in the descending process, the lifting driving device plays a role in speed reduction and buffering.

It should be noted that, in other embodiments, the lifting driving device may also adopt a conventional oil cylinder, a lead screw nut mechanism, etc., and only needs to be capable of realizing lifting driving, which is not listed here.

The transfer part comprises a frame body 26 and a transfer mechanism 27, wherein the frame body 26 of the transfer part comprises support legs 261 and a base beam 262 arranged on top of the support legs, and the support legs of the frame body 26 are fixedly assembled on the lifting beam 15 of the lifting part, so that the lifting beam 15 and the frame body 26 form a frame structure together. As can be seen from the above description of the lifting part, the two parallel lifting beams of the lifting part do not form a platform or a frame structure, after the frame body of the transfer part is mounted on the lifting beams, the two lifting beams are connected into a whole through the frame body to form a lifting body, and at the same time, the two base beams of the frame body of the transfer part are not connected, and the two base beams are structurally connected through the lifting beams. Of course, in other embodiments, for example, the frame body itself is a multi-layer structure, in which case, only a part of the frame body may be shared as a constituent part of the lifting body. Or the frame body is directly assembled on the guide upright post of the lifting part in a guide way, and at the moment, the frame body is not only the lifting body of the lifting part, but also the frame body of the transferring part. In other embodiments, the lifting body itself can form a reliable bearing structure, and the transfer part can use the lifting body as a frame body.
