[0030] This utility model provides a multi-point lifting device for sales purposes.

[0031] Please refer to this carefully. Figure 1 and Figure 4 A multi-point lifting device for sales includes a mounting frame 1, which includes a cross-shaped mounting shell 101. The cross-shaped mounting shell 101 has an internal mounting cavity. A lifting ring 102 is fixedly connected to the top surface of the cross-shaped mounting shell 101. The lifting ring 102 is located in the middle of the top surface of the cross-shaped mounting shell 101. Four guide grooves 103 are provided on the bottom surface of the cross-shaped mounting shell 101.

[0032] The lifting ring 102 facilitates the connection of the device to the lifting equipment for subsequent lifting of the equipment to be lifted. The guide groove 103 limits the connection block 204, so that the connection block 204 can only move along the length of the guide groove 103.

[0033] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4The mounting cavity inside the cross-shaped mounting housing 101 is equipped with four adjustment mechanisms 2. Each adjustment mechanism 2 includes a servo motor 201 fixedly connected to the inner wall of the cross-shaped mounting housing 101. A lead screw 202 is fixedly connected to the output end of the servo motor 201. A slider 203 is threadedly connected to the surface of the lead screw 202. A connecting block 204 that slides in contact with the guide groove 103 is fixedly connected to the bottom surface of the slider 203. A bearing seat 205 is fixedly installed on the inner wall of the guide groove 103. The end of the lead screw 202 away from the servo motor 201 is rotatably connected through the bearing and the bearing seat 205.

[0034] The start of the servo motor 201 will drive the lead screw 202 to rotate. The connecting block 204 is limited by the guide groove 103, and the slider 203 is limited by the connecting block 204. Therefore, the rotation of the lead screw 202 will drive the slider 203 and the connecting block 204 to move along the length of the guide groove 103. The moving connecting block 204 can drive the hook 504 to move, thereby realizing the adjustment of the lifting point to adapt to equipment of different sizes and models. The four servo motors 201 are controlled separately. By starting different servo motors 201, the positions of the four lifting points of the device can be adjusted separately.

[0035] Please refer to this carefully. Figure 3 and Figure 4 Each adjustment mechanism 2 is provided with two support components 3 for supporting the adjustment mechanism 2. The support component 3 includes a support rod 301 fixedly connected to the inner wall of the cross mounting shell 101, and a support ring 302 fixedly connected to the side of the slider 203. The reserved hole of the support ring 302 slides in contact with the surface of the support rod 301.

[0036] The movement of slider 203 will also cause support ring 302 to slide on support rod 301. The cooperation between support rod 301 and support ring 302 can guide slider 203, making slider 203 move more stably. At the same time, during hoisting, slider 203 will also be subjected to downward pulling force. The cooperation between support ring 302 and support rod 301 can support slider 203 and improve the structural strength of the device.

[0037] Please refer to this carefully. Figure 3 and Figure 4 The adjustment mechanism 2 is also provided with two sliding components 4 for guiding the adjustment mechanism 2. The sliding component 4 includes a connecting rod 401 fixedly connected to the side of the connecting block 204. A pulley 402 is rotatably connected to the end of the connecting rod 401 away from the connecting block 204. The bottom surface of the pulley 402 is in contact with the inner bottom wall of the cross mounting shell 101.

[0038] During the movement of the connecting block 204, the connecting rod 401 will also move. The movement of the connecting rod 401 will cause the pulley 402 to rotate on the inner bottom wall of the cross mounting shell 101. The smoothness of the movement of the slider 203 and the connecting block 204 is further improved by the cooperation of the connecting rod 401 and the pulley 402.

[0039] Please refer to this carefully. Figure 1 and Figure 5 Each of the adjustment mechanisms 2 is equipped with a hoisting wire assembly 5. The hoisting wire assembly 5 includes a first hoisting wire 501 fixedly connected to the bottom surface of the connecting block 204. A connecting ring 502 is sleeved on the lower end of the first hoisting wire 501. A second hoisting wire 503 is sleeved on the lower end of the connecting ring 502. A hook 504 is fixedly connected to the lower end of the second hoisting wire 503.

[0040] The second lifting line 503 is detachably connected to the first lifting line 501 via a connecting ring 502. Depending on the actual working needs, the second lifting line 503 of the appropriate length and the hook 504 matching the second lifting line 503 can be replaced for different sizes and models of equipment to avoid the first lifting line 501 and the second lifting line 503 being too short, causing the bottom of the cross mounting shell 101 to contact the top of the equipment to be lifted.

[0041] Working principle: First, the device is connected to the lifting equipment via the lifting ring 102. Then, the servo motor 201 is started. The start of the servo motor 201 will drive the lead screw 202 to rotate. The connecting block 204 is limited by the guide groove 103, and the slider 203 is limited by the connecting block 204. Therefore, the rotation of the lead screw 202 will drive the slider 203 and the connecting block 204 to move along the length direction of the guide groove 103. The moving connecting block 204 can drive the hook 504 to move, thereby realizing the adjustment of the lifting point. After the lifting point composed of the four adjustment mechanisms 2 and the lifting line assembly 5 is adjusted, the hook 504 is connected to the lifting ring of the equipment to be lifted. By adjusting the relative positions of multiple lifting points, this device can stably lift the equipment to be lifted, and has high flexibility.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
