Problems solved by technology

[0002] The synchronous lifting mechanism lifts heavy objects by synchronously raising and lowering multiple lifting platforms. The existing synchronous lifting mechanism requires a large height space and a relatively complicated structure, which is not conducive to application in occasions that require height space.
For example, in the three-dimensional warehouse for storing steel plates, the height of the synchronous lifting mechanism is required to be 260mm, and the steel plate with a length X width of 6mX2m and a weight of 6 tons must be lifted by a certain distance. The traditional synchronous lifting mechanism cannot adapt to this occasion.

Embodiment 1

[0030] Such as figure 1 Shown is a fork frame synchronous lifting mechanism disclosed in the embodiment of the present invention, which includes a base 1 and a lifting unit 2 arranged on the base 1 . The lifting unit 2 includes two fork lift platforms 21 and a drive transmission mechanism. The drive transmission mechanism includes a horizontal hydraulic cylinder 28 .

[0031] Two fork lift platforms 21 are arranged at intervals on the base 1 , and each fork lift platform 21 includes a bottom frame 22 , a top platform 23 , and a first fork frame 24 and a second fork frame 25 . The two top platforms 23 can be used to lift one end of a heavy object (such as a steel plate) respectively. The bottom frame 22 is horizontally and fixedly connected to the base 1 , and the top platform 23 is located above the bottom frame 22 and parallel to the bottom frame 22 . The top platform 23 and the bottom frame 22 may have the same configuration.

[0032] see figure 2 , In this embodiment,...

Embodiment 2

[0043] see Figure 6 , in another embodiment of the present invention, the lifting unit 2 of the synchronous lifting mechanism of the fork frame can be arranged at least two at intervals. A horizontal synchronization rod 3 is connected between any two adjacent lifting units 2 . At least one synchronous rod 3 is provided, and in this embodiment, two synchronous rods 3 are connected side by side. The two ends of each synchronizing rod 3 are respectively hinged on the second fork frame 25 of the fork frame lifting platform 21 adjacent to the end, and the two ends of the synchronizing rod 3 can also be hinged on the first fork frame 24 or the top platform 23 etc. places. When lifting heavy objects with a long length, two or more lifting units 2 can be used to distribute the weight of the heavy objects to a top platform 23, and the more the number of lifting units 2, the greater the lifting capacity it provides. The total lift force is also greater, which can ensure the safety an...

Embodiment 3

[0045] see Figure 7 and Figure 8 , in this embodiment discloses a synchronous elevating mechanism for a fork frame, which is different from Embodiment 1 in that the horizontal hydraulic cylinder 28 does not use a double-rod cylinder, but directly adopts an ordinary cylinder, and the The horizontal hydraulic cylinder 28 is arranged on the same side of the two fork lift platforms 21 , that is, the horizontal hydraulic cylinder 28 is located outside the two fork lift platforms 21 . The piston rod 281 of the horizontal hydraulic cylinder 28 is connected to the first connecting rod 26, and the first connecting rod 26 is connected to the second fork frames 25 of the two fork frame lifting platforms 2 at the same time. When the horizontal hydraulic cylinder 28 moves, it can drive the first connecting rod 26 to move left and right, thereby driving the two second fork frames 25 to move synchronously, thereby driving the two top platforms 23 to move up and down synchronously. Since ...

Abstract

The present invention proposes a fork frame synchronous lifting mechanism, including a base and a lifting unit, the lifting unit includes at least two fork frame lifting platforms and a drive transmission mechanism, each fork frame lifting platform includes a bottom frame, a top platform, at least two Parallel first fork frames, second fork frames that are equal in length to each first fork frame and adapted respectively, the middle part of the second fork frame is hinged with the middle part of the first fork frame, and the two fork frame The first fork frame and the second fork frame of the lifting platform are respectively parallel to each other; the driving transmission mechanism includes: a horizontal hydraulic cylinder, the piston rod of which is connected with the second fork frame of the two fork frame lifting platforms or with the The first fork frames of the two fork frame lifting platforms are connected, and the linkage mechanism is pushed to move horizontally so as to drive the two fork frame lifting platforms to move up and down synchronously. The synchronous lifting mechanism of the fork frame of the present invention has a lower height of the horizontal hydraulic cylinder of the lifting unit and less requirement on the height space, and can be used in occasions where the height is limited.
