[0030] See also Figures 1 to 3 As shown, the utility model discloses a specific embodiment of a lifting support structure, comprising: a mounting frame 1, a driving mechanism 2 mounted on the mounting frame 1, a lifting mechanism 3 and a storage platform 4; the lifting mechanism 3 is used to support the storage platform 4, the storage platform 4 is used to place a workpiece 5, the driving mechanism 2 is connected to the lifting mechanism 3 by transmission, and is used to drive the lifting mechanism 3 to lift; the lifting mechanism 3 includes a first lift 31 and a second lift 32, the first lift 31 and the second lift 32 are connected to the driving mechanism 2 by transmission, and the first lift 31 and the second lift 32 are both connected to the storage platform 4.

[0031] Specifically, by providing a first elevator 31 and a second elevator 32 to jointly support the storage platform 4, the supporting force and stability of the supporting structure are improved, and the first elevator 31 and the second elevator 32 are both driven to rise and fall by a driving mechanism 2. When it is necessary to drive the storage platform 4 to rise and fall, the driving mechanism 2 drives the first elevator 31 and the second elevator 32 to rise and fall together, which greatly improves the lifting and lowering synchronization rate of the first elevator 31 and the second elevator 32, so that the storage platform 4 always remains balanced during the lifting process.

[0032] In a specific embodiment, the first elevator 31 is provided with a first driving worm (not shown in the figure), and the second elevator 32 is provided with a second driving worm (not shown in the figure); the driving mechanism 2 is transmission-connected to the first driving worm, and the first driving worm is transmission-connected to the second driving worm; when the driving mechanism 2 drives the first driving worm to rotate, the second driving worm rotates synchronously, so that the first elevator 31 and the second elevator 32 are lifted and lowered synchronously.

[0033] Specifically, a connecting rod 33 is provided between the first driving worm and the second driving worm, and the connecting rod 33 is fixedly connected to the first driving worm and the second driving worm. When the driving mechanism 2 drives the first driving worm to rotate, the first driving worm drives the second driving worm to rotate synchronously through the connecting rod 33, so that the first elevator 31 and the second elevator 32 are synchronously lifted and lowered, so that the storage platform 4 always maintains balance during the lifting process. More specifically, the first elevator 31 also includes an elevator housing 311, a worm wheel and an elevator screw 312. The center of the worm wheel is an internal thread structure. The first driving worm and the worm wheel are both located in the elevator housing 311, and the first driving worm is connected to the worm wheel in a driving manner. One end of the elevator screw 312 is located in the elevator housing 311 and is screwed to the worm wheel. The other end extends out of the elevator housing 311 and is used to support the storage platform 4. When the first driving worm rotates, the worm wheel and the lifting screw 312 are driven to rotate, and the rotation circle ratio of the first driving worm and the lifting screw 312 can be controlled by changing the internal thread density of the worm wheel and the thread density of the lifting screw 312, thereby controlling the lifting speed of the lifting screw 312, so that the storage platform 4 can be stably lifted and lowered. The structure of the second elevator 32 is the same as that of the first elevator 31, and the first elevator 31 and the second elevator 32 are detachably mounted on the mounting frame 1 by screws, so that the elevator can be replaced according to the required lifting speed. Through the above-mentioned first elevator 31 and the second elevator 32, the bearing capacity of the lifting support structure is effectively improved, and the structure is stable and reliable, and easy to control.

[0034] In a specific embodiment, the driving mechanism 2 includes a rotating power member 21 mounted on the mounting frame 1 and a transmission assembly 22 connected to the rotating power member 21 and the first driving worm.

[0035] Specifically, the transmission assembly 22 includes a driving wheel 221, a driven wheel 222 and a transmission belt 223, and the rotating power member 21, the driving wheel 221, the transmission belt 223, the driven wheel 222 and the first driving worm are sequentially connected in transmission. More specifically, the mounting frame 1 is provided with a vertical mounting plate 11, the rotating power member 21 is a rotating motor or a rotating cylinder, and is horizontally mounted on one side of the vertical mounting plate 11, and the driving wheel 221 is vertically mounted on the other side of the vertical mounting plate 11, and is in transmission connection with the output end of the rotating power member 21. The driving mechanism 2 provided in this embodiment has a simple structure and stable transmission.

[0036] In a specific embodiment, the transmission assembly 22 further includes a tensioning wheel 224 . The tensioning wheel 224 is disposed between the driving wheel 221 and the driven wheel 222 and is transmission-connected to the transmission belt 223 .

[0037] Specifically, the tensioning wheel 224 and the driving wheel 221 are vertically installed on the same side of the vertical mounting plate 11, the driving wheel 221 and the driven wheel 222 are located on the inner side of the transmission belt 223, and the tensioning wheel 224 is located on the outer side of the transmission belt 223. Through the tensioning wheel 224, the tensioning force can be adjusted according to the tightness of the transmission belt 223, so that the transmission assembly 22 is stable, safe and reliable. Preferably, the driving wheel 221, the tensioning wheel 224 and the driven wheel 222 together tension the transmission belt 223 into a right angle shape, which effectively reduces the occupied space of the transmission assembly 22 and facilitates the structural layout.

[0038] In a specific embodiment, a protective shell 225 is provided on the outer periphery of the transmission component 22 so that the transmission component 22 is always in a clean and safe working environment, does not require frequent maintenance and cleaning, and prolongs the service life of the transmission component 22.

[0040] Specifically, the clamping mechanism 6 includes a clamping frame 61, and the clamping frame 61 is provided with a plurality of clamping needles 62, which are used to clamp the workpiece 5. The clamping mechanism 6 can prevent the workpiece 5 from bumping during the lifting process, and the contact area between the clamping needles 62 and the workpiece 5 is small, which is convenient for performing other operations on the workpiece 5.

[0043] In a specific embodiment, the placement platform 4 is composed of two placement rails 41 , and the two placement rails 41 are respectively used to support two sides of the workpiece 5 .

[0044] Specifically, by setting the storage platform 4 as two storage rails 41, the workpiece 5 can achieve position transfer between the storage platform 4 and other platforms during the lifting process. More specifically, when the workpiece 5 is on the storage platform 4 and the other platforms are below the workpiece 5, the storage platform 4 is lowered by the driving mechanism 2 and the lifting mechanism 3, and the workpiece 5 can be transferred to the other platforms. When the workpiece 5 is on the other platforms and above the storage platform 4, the storage platform 4 is raised by the driving mechanism 2 and the lifting mechanism 3, and the workpiece 5 can be transferred to the storage platform 4.

[0045] In a specific embodiment, there are two groups of lifting mechanisms 3 , and the two groups of lifting mechanisms 3 support two storage rails 41 respectively.

[0046] Specifically, the two sets of lifting mechanisms 3 are both connected to the same driving mechanism 2, so that the two storage rails 41 are lifted and lowered synchronously, so that the workpiece 5 always maintains balance during the lifting process.
