Description

Technical Field

[0001] This utility model relates to the field of hydraulic technology, and more specifically, to a hydraulic lifting device. Background Technology

[0002] Hydraulic lifts primarily achieve their lifting function through the pressure transmission of hydraulic oil. Their scissor-lift mechanism provides high stability during lifting, and their large working platform and high load-bearing capacity facilitate the transport of goods at heights.

[0003] Chinese patent application CN220664771U discloses a hydraulic lifting device, including a hydraulic lift platform. The upper end of the hydraulic lift platform is provided with a support platform, and a loading / unloading mechanism is also included on the support platform for loading and unloading goods. The loading / unloading mechanism includes two symmetrically arranged mounting slots on the support platform, with L-shaped plates slidably connected to the two mounting slots. Loading / unloading plates are provided at opposite ends of the two L-shaped plates. A drive mechanism is provided on the support platform for driving the two loading / unloading plates. Through the loading / unloading mechanism, under the driving action of the drive mechanism and the pushing action of the pushing mechanism, loading and unloading of goods on the support platform is achieved without manual handling. This improves the efficiency of transporting goods to higher places and reduces the labor intensity of workers and the safety risks of working at heights. However, during use, for safe handling of goods, the support platform needs to be placed as close as possible to the shelf. This means that in the initial stage of use, the position of the hydraulic lifting device needs to be adjusted to be close to the shelf to minimize the distance between the support platform and the shelf.

[0030] Example

[0031] The present invention will now be further described with reference to the accompanying drawings.

[0032] like Figures 1 to 6 As shown, this embodiment provides a hydraulic lifting device, including a hydraulic lift 10 and a support platform 11 installed on the hydraulic lift 10. The support platform 11 is provided with a loading and unloading mechanism 12 for loading and unloading goods. It also includes a rolling seat 13, which is integrally installed on the support platform 11. Multiple mounting slots are arranged side by side on the rolling seat 13, and rolling rollers 14 are installed in the mounting slots. An upper lifting plate 15 is located on the rolling seat 13, and multiple upper slots 16 for avoiding the rolling rollers 14 are arranged side by side on the upper lifting plate 15.

[0033] It also has several flipping rods 17, which are located on both sides of the upper lifting plate 15 in the width direction. One end of the flipping rod 17 is rotatably connected to the side of the upper lifting plate 15, and the other end of the flipping rod 17 is rotatably connected to the side of the rolling seat 13. An electric telescopic rod 18 is installed between the side of the rolling seat 13 and the flipping rod 17.

[0034] The working principle and beneficial effects of the above technical solution are as follows:

[0035] This utility model discloses a hydraulic lifting device. After the hydraulic lift 10 stops near the shelf, in the initial state, the upper plate is in the first position. The goods are transported onto the rolling seat 13. The hydraulic lift 10 works, thereby driving the support platform 11 to rise to a preset height. After the loading and unloading mechanism 12 clamps the goods, it drives the goods to move on the rolling roller 14, thereby transporting the goods to the position near the shelf. The loading and unloading mechanism 12 releases the clamp on the goods. Then the electric telescopic rod 18 works, thereby driving the flipping rod 17 connected to the electric telescopic rod 18 and the upper plate 15 connected to the flipping rod 17 to flip on the rolling seat 13 towards the position near the shelf. The upper plate is in the second position. After the goods are slightly lifted, the electric telescopic rod 18 continues to extend, and the upper plate is in the third position. The upper plate 15 carries the goods to be placed on the shelf. The loading and unloading mechanism 12 continues to transport the goods, thereby sending the goods into the shelf. The present invention provides a hydraulic lifting device. After observing the position of the shelf, the hydraulic lift 10 only needs to be stopped close to the shelf. Then the lifting plate 15 assists in moving the goods onto the shelf, and the loading and unloading mechanism 12 continues to move the goods, thereby sending the goods into the shelf.

[0036] Specifically, the fixed end of the electric telescopic rod 18 is rotatably connected to the side of the rolling seat 13, and the telescopic end of the electric telescopic rod 18 is rotatably connected to the middle of the flipping rod 17. When the telescopic end of the electric telescopic rod 18 extends, the flipping rod 17 drives the upper lifting plate 15 to move forward, and when the telescopic end of the electric telescopic rod 18 retracts, the flipping rod 17 drives the upper lifting plate 15 to move backward.

[0037] In one embodiment, an equal number of electric telescopic rods 18 are provided with the flipping rods 17, and the number of flipping rods 17 is ten, which are installed in two groups of five on both sides of the lifting plate 15 in the width direction.

[0038] In one embodiment, the shaft end of the rolling roller 14 is rotatably mounted on the inner wall of the mounting groove.

[0039] In one embodiment, the loading / unloading mechanism 12 includes:

[0040] The transverse sliding groove 19, two parallel transverse sliding grooves 19 are opened on the support platform 11, the rolling seat 13 is located between the two transverse sliding grooves 19, and a transverse sliding screw 20 is rotatably installed in each transverse sliding groove 19;

[0041] A transverse sliding screw block is slidably installed in the transverse sliding groove 19 and sleeved on the transverse sliding lead screw 20;

[0042] L-shaped support frame 21, the vertical section of L-shaped support frame 21 is connected to the transverse sliding screw block, and the horizontal section of L-shaped support frame 21 is equipped with a clamping plate assembly 22 for clamping goods.

[0043] Drive pulley 23, one end of each transverse lead screw 20 is exposed on the side of the support platform 11 and is equipped with drive pulley 23, and transmission belt 24 is sleeved on the two drive pulleys 23;

[0044] The transverse motor 25 is fixedly connected to the side end of the support platform 11 via a side mounting bracket, and the output end of the transverse motor 25 is connected to one of the transverse lead screws 20.

[0045] The working principle and beneficial effects of the above technical solution are as follows:

[0046] When the transverse motor 25 operates, it drives the transverse lead screw 20 installed at the output end of the transverse motor 25 to rotate. The two transverse lead screws 20 move synchronously through the cooperation of the drive pulley 23 and the transmission belt 25, thereby driving the transverse screw block sleeved on the transverse lead screw 20 and the L-shaped support frame 21 connected to the transverse screw block to move along the transverse groove 19, thereby driving the transport of the goods clamped by the clamping plate assembly 22.

[0047] In one embodiment, the clamping plate assembly 22 includes:

[0048] Electric actuator 26 is installed on the horizontal section of L-shaped support frame 21;

[0049] Clamping plate 27 is installed at the output end of electric actuator 26;

[0050] Telescopic rod 28 is installed between the horizontal section of L-shaped support frame 21 and clamping plate 27. Telescopic rod 28 and electric push rod 26 are arranged side by side in the horizontal direction.

[0051] The working principle and beneficial effects of the above technical solution are as follows:

[0052] When the electric actuator 26 operates, it drives the clamping plate 27 connected to it to move along the extension and retraction direction of the telescopic rod 28 to clamp the goods and facilitate the handling of the goods.

[0053] In one embodiment, a buffer plate is mounted on the clamping plate 27 via a spring rod.
