Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to a hoisting mechanism for stone processing. Background Technology

[0002] Stone is a high-end building decoration material widely used in interior and exterior decoration design, curtain wall decoration and public facility construction. The most common types of stone on the market are natural stone and artificial stone, while stone lifting equipment is a tool used to lift and move stone.

[0003] Currently, during exterior wall construction, the transportation of stone slabs is inconvenient due to the high construction location. Most hoisting devices are simply composed of hoisting ropes and support plates. When moving up and down, the stability of the stone clamping cannot be guaranteed. Moreover, relying on manual knotting or simple hooks, they are prone to loosening when vibrating or tilting. Generally, stones with sharp edges can easily break the ropes, which can easily lead to falling objects accidents. In conclusion, the traditional hoisting rope + support plate structure can no longer meet the core requirements of modern industry for safety, efficiency, and zero damage. Therefore, a hoisting mechanism for stone processing is proposed to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] like Figure 1-3As shown, the present invention proposes a hoisting mechanism for stone processing, comprising two base plates 1 and a frame 2 connected to the top of the two base plates 1. A lifting platform 3 is provided on the inner side of the frame 2. A lifting mechanism for driving the lifting platform 3 to rise and fall is provided inside the frame 2. It also includes multiple clamping frames 4 arranged opposite to each other below the lifting platform 3. An inclined plate 5 is connected to the opposite side of each clamping frame 4. A driving mechanism for driving the multiple clamping frames 4 to move relative to each other is provided inside the lifting platform 3. A protective belt 41 is provided between the inner side of the multiple clamping frames 4 and the lifting platform 3.

[0025] In an optional embodiment, the protective strap 41 is an elastic strap, and its two ends are respectively connected to the lower inner side of the clamping frame 4 and the bottom end of the lifting platform 3.

[0026] It should be noted that the inclined plates 5 are arranged opposite each other, and the clamping frames 4 on both sides move them to clamp the stone from both sides. Due to the inclined surfaces, the opposite side can better extend under the stone, clamping it more quickly. The protective strips 41 are made of highly elastic rubber. When the stone is irregularly shaped, the protective strips 41 on both sides can better contact the surface of the stone. At this time, the protective strips 41 are stretched, and the tension generated can better fix the stone. There are two sets of drive mechanisms, and the two sets of drive mechanisms are electrically connected to the lifting mechanism. By using PLC control technology, the two sets of drive mechanisms can run simultaneously, and then the lifting mechanism drives the lifting to complete the operation of raising the stone after clamping.

[0027] In an optional embodiment, the drive mechanism includes a hydraulic cylinder 61, a connecting frame 62, two gears 63, two hinge rods 64, and two racks 65. The hydraulic cylinder 61 is located at the top of the lifting platform 3, and the telescopic rod is vertically downward. The connecting frame 62 is connected to the bottom end of the telescopic end of the hydraulic cylinder 61. The two gears 63 are rotatably connected to the front side wall of the lifting platform 3 through a rotating shaft, and are respectively hinged to the left and right sides of the connecting frame 62 through the two hinge rods 64. The two racks 65 are slidably disposed on the bottom wall of the lifting platform 3 and mesh with the two gears 63 respectively. Multiple clamping frames 4 are respectively connected to the bottom ends of the two racks 65.

[0028] It should be noted that when driving the two clamping frames 4, the hydraulic cylinder 61 is activated, causing its telescopic rod to move vertically downwards. The movement is transmitted through the connecting frame 62 and the two hinge rods 64, which in turn drive the gear 63 to rotate. The gear 63 drives the two racks 65 to move the two clamping frames 4 relative to each other or in opposite directions, thereby clamping the stone.

[0029] In an optional embodiment, the platform 2 includes two support columns 21 and a crossbeam 22, which are respectively vertically arranged at the top of the two base plates 1, and the crossbeam 22 connects the two support columns 21.

[0030] In an optional embodiment, the lifting mechanism includes a dual-axis motor 71, two rotating rods 72, two threaded rods 73, two first bevel gears 74, and two second bevel gears 75. The two threaded rods 73 are rotatably mounted between the upper and lower walls of the two support columns 21, respectively. The dual-axis motor 71 is mounted on the bottom wall of the crossbeam 22. The two rotating rods 72 are coaxially connected to the two output shafts of the dual-axis motor 71, respectively. The two first bevel gears 74 are coaxially fixedly sleeved on the two threaded rods 73, respectively. The two second bevel gears 75 are coaxially fixedly sleeved on the two rotating rods 72, respectively, and mesh with the two first bevel gears 74.

[0031] In an optional embodiment, lifting plates 31 are connected to both the left and right sides of the lifting platform 3, and are threadedly connected to two threaded rods 73 respectively.

[0032] It should be noted that when the lifting platform 3 is raised or lowered, the dual-axis motor 71 is started to drive the two rotating rods 72 to rotate. The two first bevel gears 74 and the two second bevel gears 75 drive the two threaded rods 73 to rotate, thereby driving the two lifting plates 31 to move up and down. Each of the two support columns 21 has a sliding window on its opposite side that is adapted to the size of the two lifting plates 31 to limit the lifting height of the two lifting plates 31.

[0033] In an optional embodiment, pulleys that contact the ground are provided under both base plates 1, and support frames are connected between the front and rear sides of the two support columns 21 and the top of the base plates 1.

[0034] It should be noted that the entire device can be moved by the pulleys, and the triangular support frame can improve the stability of the support column 21.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
