Description

Technical Field

[0001] This invention relates to the field of tracheal suction lifting machine technology, and particularly to a lifting mechanism for a tracheal suction lifting machine. Background Technology

[0002] Pneumatic suction lifters, utilizing the principle of negative pressure adsorption, are widely used in workpiece lifting operations in light industry, machinery, and logistics. Their lifting mechanism is the core component for grasping and transferring items. Most existing pneumatic suction lifters employ suction cups, which pick up items and simultaneously allow air to enter through the suction port to reduce the vacuum. However, some items are unsuitable for suction cup lifting and must be hooked. Therefore, when releasing the item, the hook may spring upwards due to the negative pressure, potentially causing injury to the operator, especially with single-handed suction lifters.

The sealing assembly 2 has an air inlet 221 at its bottom; Buffer assembly 3 is slidably connected to sealing assembly 2, with its upper end located inside hollow cavity 21. A rubber sealing block 31 is installed on buffer assembly 3, which is used to seal air inlet 221. The hook is detachably connected to the lower end of the buffer assembly 3.

[0019] Furthermore, such as Figures 1-2 As shown in Figures 5, 7, and 8, in this embodiment, the sealing assembly 2 includes: The first fixed plate 21 has an air inlet 221 located in the middle of the first fixed plate 21; A plurality of rubber sealing rings 22 are stacked and arranged in layers and installed on the first fixed plate 21; A metal ring 24 is installed inside each rubber sealing ring 22. The metal ring 24 is used to strengthen the structural strength of the rubber sealing ring 22. At least one pair of first fixing screws 25 pass through the metal rings 24 inside the first fixing plate 21 and several rubber sealing rings 22, and are then fixedly connected to the universal rotating plate 1. The first fixing screws 25 fix the first fixing plate 21 and the rubber sealing rings 22 together to the bottom of the universal rotating plate 1. When the rubber block covers the air inlet 221, the hollow cavity 21 forms a sealed cavity.

[0020] Preferably, such as Figure 5 ,7 As shown in Figure 8, in this embodiment, the metal ring 24 is made of stainless steel.

[0021] Furthermore, such as Figure 5 , 7 As shown, in this embodiment, a pair of first guide holes 222 are provided on the first fixed plate 21.

[0022] Furthermore, such as Figure 2 , 5 As shown in Figures 7 and 8, in this embodiment, the buffer component 3 includes: The first fixing plate 31 and the rubber sealing block 31 are installed at the bottom of the first fixing plate 31; A pair of guide rods 33 are installed at both ends of the first fixed plate 31, corresponding one-to-one with the first guide holes 222, and are slidably connected to the corresponding first guide holes 222. Each guide rod 33 is fitted with a buffer spring 34, which is located between the first fixed plate 31 and the first fixed disk 21. Hook 4 is detachably connected to the lower end of guide rod 33.

[0023] Furthermore, such as Figure 5 , 7 As shown in ~8, in this embodiment, it also includes: a second fixing screw 35, which passes through the rubber sealing block 31 and is detachably connected to the first fixing plate 31, for fixing the rubber sealing block 31 on the first fixing plate 31.

[0024] Furthermore, such as Figures 1-2 As shown in Figures 5 and 7, this embodiment also includes a reinforcing component 5, which is connected to the first fixed plate 21 and a pair of guide rods 33 respectively, and is used to enhance the structural stability of the sealing component 2 and the buffer component 3.

[0025] Furthermore, such as Figures 1-2 As shown in Figures 5 and 7, in this embodiment, the reinforcing component 5 includes: The second fixed plate 51 is slidably connected to a pair of guide rods 33; The upper end of the fixed sleeve 52 is fixedly connected to the first fixed plate 21, and the lower end is fixedly connected to the second fixed plate 51.

[0028] Furthermore, such as Figures 1-2 As shown in Figures 7 and 8, this embodiment also includes a reinforcing plate 7, which is fixedly connected to the hook 4 and the third fixing plate 6 respectively.

[0029] Working principle: When the hook 4 is hung on an item, the hook 4 drives the guide rod 33 to move downward, the guide rod 33 drives the first fixed plate 31 to move downward, and the first fixed plate 31 drives the rubber sealing block 31 to move downward, so that the rubber sealing block 31 seals the air inlet 221, forming a sealed space inside the hollow cavity 21. The lifting rod of the suction crane can be operated to drive the item to rise or fall. When the item reaches the designated position, the moment the hook 4 is released from the item, the buffer spring 34 drives the first fixed plate 31 to move upward through the spring force. External air enters from the air inlet 221, reducing the vacuum in the air pipe 8, thus preventing the lifting mechanism from rebounding upward at the moment the item is released from the hook 4.

[0030] Above, refer to Figures 1-8 The hoisting mechanism of the tracheal suction hoist according to an embodiment of the present invention is described, which has a buffer component 3 that can open the air inlet at the moment of lowering the item, so that the hook 4 will not pop up instantly, greatly improving the safety of hoisting operations.
