DETAILED DESCRIPTION

[0026] like Figure 1-Figure 6As shown, the utility model is an anti-falling logistics clamping machine including a forklift 1, the forklift 1 including a lifting mechanism 2, the lifting mechanism 2 is connected with a fixed arm 3, the fixed arm 3 includes two arms and a connecting plate, the two arms are fixedly connected to the connecting plate, the two arms are symmetrical, the side of the connecting plate away from the arm is slidably connected to the lifting mechanism 2 up and down, the ends of the two arms away from the connecting plate are connected with a cover assembly 5, the cover assembly 5 is connected between the two arms, the cover assembly 5 includes a fixed half shell 501 and a movable cover shell 503, the fixed half shell 501 includes a semicircular arc plate and two side plates, the two side plates are symmetrical, and the two side plates are connected along the semicircle The arc plate is fixedly connected to the left and right sides of the semicircular plate in the axial direction, the two arm parts of the fixed arm 3 are respectively fixedly connected to the outer sides of the two side plates of the fixed half shell 501, the movable cover shell 503 includes a semicircular plate and two side plates, the two side plates are fixedly connected to the left and right sides of the semicircular plate along the axial direction of the semicircular plate, the two side plates are symmetrical, the movable cover shell 503 is covered on the outer side of the fixed half shell 501, the two side plates of the movable cover shell 503 are respectively rotatably connected to the two arm parts of the fixed arm 3, the two side plates of the fixed half shell 501 are fixedly connected to the opposite surfaces of the two side plates, the front end of the piston rod of the cylinder 7 is fixedly connected to the clamping plate 8, and the two clamping plates 8 are symmetrical.

[0027] The logistics personnel enter the cab of the forklift 1, and drive the forklift 1 close to the goods, and then operate the lifting mechanism 2 to drive the fixed arm 3, the cover assembly 5 and the clamping plate 8 to move downward. After the transported goods are located between the two clamping plates 8, the cylinder 7 drives the two clamping plates 8 to move in the middle, and the clamping plates 8 are used to clamp the goods. After the goods are clamped and fixed, the lifting mechanism 2 is operated again to control the fixed arm 3, the cover assembly 5, the clamping plate 8 and the goods to move upward to achieve the goods clamping; in addition, after the clamping plates 8 clamp the goods, the movable cover 503 can be rotated downward so that the movable cover 503 and the fixed half shell 501 form a closed The cargo is confined inside the closed cover assembly 5; the logistics personnel then drives the forklift 1 to the destination, and after arriving at the destination, rotates the movable cover 503 to open the cover assembly 5, and drives the fixed arm 3, the cover assembly 5, the clamping plate 8 and the cargo to move downward through the lifting mechanism 2. When the cargo falls stably on the ground, the clamping plate is released to complete the unloading operation. Even if the cargo accidentally slips from between the clamping plates 8 during the transportation process, it is absolutely impossible for the cargo to fall from the cover assembly 5, thereby avoiding damage caused by the cargo falling to the ground, and also avoiding the situation where the cargo falls and damages other cargo or accidentally injures other logistics personnel.

[0028] Note that if you find it is stuck or difficult to rotate the movable cover 503, the goods inside the cover assembly 5 may have fallen out. At this time, forcibly opening the movable cover 503 may cause the goods to fall out. At this time, you can first lower the cover assembly 5 to a lower distance from the ground to open it. When opening, you should pay attention to the situation inside the cover assembly 5 and operate slowly. If necessary, you can place a cushion on the bottom for protection.

[0029] Manual rotation of the movable cover shell 503 is rather time-consuming and laborious, and also involves certain risks. Therefore, it is possible to consider making the movable cover shell 503 rotate automatically. To solve this problem, the utility model has outer rotor motors 4 fixedly connected to the two arm portions of the fixed arm 3. The outer rotor motor 4 includes a central axis and an outer rotating shell. Both ends of the central axis pass through the outer rotating shell, one end of the central axis is fixedly connected to the arm portion of the fixed arm 3, the outer rotating shell is fixedly connected to the outer wall of the side plate of the movable cover shell 503, and one end of the central axis not connected to the fixed arm 3 is fixedly connected to the outer side of the side plate of the fixed half shell 501.

[0030] Automatic rotation of the movable cover 503 is achieved by setting up the outer rotor motor 4. The outer rotor motor 4 is a structure frequently used in this field. For example, the driving wheels of two-wheeled electric vehicles and the linear motors of some drum washing machines use the outer rotor motor 4. Therefore, the working principle and detailed usage of the outer rotor motor 4 will not be described in detail here.

[0032] The setting of the arc groove 504 and the metal sliding button 502 provides a guide for the rotation of the movable cover shell 503. The position of the metal sliding button 502 may limit the movable cover shell 503. Since the movable cover shell 503 is generally required to rotate 180°, the metal sliding button 502 can be set on the horizontal plane where the rotation center of the movable cover shell 503, that is, the axis of the outer rotor motor 4, is located, and the arc groove 504 is set to an arc shape with a part that is more than a semicircular arc at both ends, and the extra parts at both ends are for accommodating the metal sliding button 502.

[0033] The two clamping plates 8 are both provided with a connecting air chamber 801, a vent hole I 802 and a vent hole II 803.

[0034] The logistics personnel control the clamping plate 8 to move in the center through the cylinder 7. After clamping the goods, the air pump 901 is started to pump air through the air pump 901, and the gas in the connected air bin 801 is pumped out, so that the connected air bin 801 and the vent hole I 802 are in a negative pressure state, so that the clamping plate 8 can clamp the goods more tightly. The setting of the telescopic tube 903 facilitates the arrangement of the air extraction pipeline.

[0035] The movable cover 503 is connected to a support assembly 6, which includes an outer shell 601, a guide rail 602, a servo motor 603, a wire rod 604, a lifting plate 605, a guide slider 606 and a support rod 607. The outer shell 601 is fixedly connected to the outer wall of the movable cover 503, the guide rail 602 is fixedly connected to the inner wall of the outer shell 601, the servo motor 603 is fixedly connected to the inner top wall of the outer shell 601, and the wire rod 604 is fixedly connected to the output of the servo motor 603.

[0036] When the clamping plate 8 stably clamps the goods and the cover shell assembly 5 is closed, the support assembly 6 is located directly below the goods. At this time, the servo motor 603 is started, and the metal wire rod 604 is driven to rotate by the servo motor 603. The guide rail 602 and the guide slider 606 limit the movement trajectory of the lifting plate 605, so that the lifting plate 605 can move upward under the rotation drive of the metal wire rod 604, and the end of the support rod 607 is extended into the movable cover shell 503 and against the bottom of the goods to support the goods and prevent the goods from slipping from between the two clamping plates 8, thereby further improving the anti-falling effect of the goods.

[0037] Two support rods 607 are fixedly connected to the lifting plate 605, and the two support rods 607 are linearly evenly distributed along the length direction of the support rods 607.
