[0004] Although existing technology can achieve a 90° rotation operation for box-shaped components, the limiting effect on the box-shaped components during rotation is insufficient, posing certain safety risks, and it is inconvenient to automatically lock the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting device for flipping box-shaped components, so as to solve the problems mentioned in the background art, such as insufficient limiting effect on box-shaped components, certain safety risks, and the need for manual adjustment of the rotation angle, which is inconvenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for flipping box-shaped components, comprising a vehicle body, a support frame fixedly connected to the top surface of the vehicle body, a rotating rod rotatably connected to the inner wall of the support frame, an adjustable support assembly fixedly connected to the outer wall of the rotating rod, and quick-locking assemblies at both ends of the rotating rod. The adjustable support assembly acts on the box-shaped component to support and limit its movement, and the quick-locking assembly acts on the rotating rod to automatically lock it.

[0007] As a preferred technical solution of this application, the adjustable support assembly includes a fixed frame fixedly connected to the outer wall of the rotating rod, a support plate fixedly connected to one side surface of the fixed frame, a lifting lug fixedly connected to one side surface of the support plate, a vertical plate fixedly connected to the top surface of the support plate, a positioning insert plate and an adjustment rail fixedly connected to the top surface of the vertical plate, and fixing holes evenly spaced on one side surface of the adjustment rail.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This lifting device for flipping box-shaped components effectively solves the problem of limiting the position during the flipping process of box-shaped components through the coordinated design of adjustable support components and self-locking mechanism. The limiting plate is height-adjustable through the adjustment rail to adapt to box-shaped components of different sizes. The rubber anti-slip pad increases friction and counteracts the inertial force of flipping, ensuring the stability of the component without deviation. Furthermore, the cooperation of the locking disc, pin hole, and spring pin enables the support plate to achieve rapid positioning when flipped at 0° or 90°, preventing the box-shaped component from falling accidentally. In addition, the counterweight lowers the center of gravity, and combined with the movable characteristics of the vehicle body, it effectively improves stability and workshop transfer flexibility. The specific details are as follows: 1. When limiting the position, place the box-shaped component on the surface of the support plate. The support block on the top of the vehicle body can stably support the support plate and the box-shaped component. Then, insert one side of the limiting plate into the outer wall of the positioning plate, and the fixing block is sleeved on the outer wall of the adjusting rail. According to the different dimensions of the box-shaped component, the position of the limiting plate is adjusted and fixed. The upper and lower sides of the box-shaped component are limited by the limiting plate and the support plate to prevent the box-shaped component from shifting when it is flipped, thus avoiding safety accidents.

[0014] 2. When locked, the locking disc is fixedly connected to both ends of the rotating rod and rotates synchronously with the rotating rod. The pin holes on its outer wall are symmetrically distributed about the central axis. The pin holes cooperate with the external spring pin to achieve quick positioning and locking of the support plate, avoiding production line shutdown or personnel injury caused by the box-shaped component falling.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 The present invention provides the following technical solution: a lifting device for flipping box-shaped components.

[0019] Example 1: To address the safety risk posed by insufficient limiting effect on box-shaped components during flipping, this embodiment discloses a vehicle body 1, a support frame 2, a rotating rod 3, and an adjustable support assembly 4. The vehicle body 1 has a support frame 2 fixedly connected to its top surface. A rotating rod 3 is rotatably connected to the inner wall of the support frame 2. An adjustable support assembly 4 is fixedly connected to the outer wall of the rotating rod 3. Quick-locking components 5 are provided at both ends of the rotating rod 3. The adjustable support assembly 4 acts on the box-shaped component to provide support and limit its movement. Figure 4 As shown, the adjustable support assembly 4 includes a fixed frame 401 fixedly connected to the outer wall of the rotating rod 3. A support plate 402 is fixedly connected to one side surface of the fixed frame 401. A lifting lug 403 is fixedly connected to one side surface of the support plate 402. A vertical plate 404 is fixedly connected to the top surface of the support plate 402. A positioning insert 405 and an adjusting rail 406 are fixedly connected to the top surface of the vertical plate 404. Fixing holes 407 are evenly spaced on one side surface of the adjusting rail 406. Figure 2 As shown, a fixing block 408 is slidably installed on the outer wall of the adjusting rail 406. A fixing screw 409 is provided on one side of the fixing block 408. A limit plate 410 is fixedly connected to one side surface of the fixing block 408. Anti-slip sheets are adhered to one side surface of both the support plate 402 and the limit plate 410. The anti-slip sheets are made of rubber. Figure 1As shown, the bottom four corners of the vehicle body 1 are provided with self-locking universal wheels 6, and the top surface of the vehicle body 1 is fixedly connected with a counterweight block 7 and a support block 8. The top surface of the support block 8 is bonded with a buffer pad 9, which is made of silicone.

[0020] In use, the box-shaped component is located on the surface of the support plate 402. The support block 8 on the top of the vehicle body 1 provides stable support for the support plate 402 and the box-shaped component. One side of the limiting plate 410 is inserted into the outer wall of the positioning plate 405, and the fixing block 408 is sleeved on the outer wall of the adjusting rail 406. According to the different dimensions of the box-shaped component, the limiting plate 410 is moved downward, and the bottom of the limiting plate 410 is tightly fitted with the top surface of the box-shaped component. The limiting plate 410 and the adjusting rail 406 are fixed by the threaded engagement of the fixing screw 409 and the fixing hole 407, thereby enabling the box-shaped component to move downward. Limiting plate 410 and support plate 402 limit the upper and lower sides of the box-shaped component. The rubber anti-slip sheet increases the friction of the contact surface and effectively counteracts the inertial force during the flipping process, preventing the box-shaped component from shifting and causing safety accidents when flipping. When flipping the box-shaped component, the overhead crane is connected to the lifting lug 403, and the support plate 402 is rotated 90° by the overhead crane. During the rotation, the center of gravity of the car body 1 can be lowered by the counterweight block 7 on the top of the car body 1, which improves the stability during flipping. At the same time, the car body 1 serves as a mobile platform, which is convenient for flexible transportation within the workshop.

[0021] Example 2: To solve the problem of inconvenience in automatically locking the device, such as... Figures 1-3 and Figure 6 The technical solution shown, based on Embodiment 1, also discloses a quick-locking component 5. The quick-locking component 5 includes a locking disc 501 fixedly connected to both ends of the rotating rod 3. The outer wall of the locking disc 501 has four pin holes 502, which are symmetrically distributed about the central axis of the locking disc 501. Figure 6 As shown, a mounting shell 503 is rotatably connected to one side surface of the locking disc 501. The mounting shell 503 is rotatably connected to the rotating rod 3, and the mounting shell 503 is fixedly connected to the support frame 2. A mounting cover 504 is detachably connected to one side surface of the mounting shell 503.

[0022] In use, a spring pin is provided on one side of the mounting shell 503, and the locking disc 501 is fixedly connected to both ends of the rotating rod 3. The pin holes 502 on its outer wall are symmetrically distributed around the central axis. The quick positioning is achieved by the cooperation of the pin holes 502 and the external spring pin. When the support plate 402 is in the initial position, the pin holes 502 on the locking disc 501 are aligned with the elastic pin of the mounting shell 503, and quick locking can be completed by the spring pin. When the support plate 402 is rotated 90 degrees, the pin holes 502 on the locking disc 501 are aligned with the elastic pin of the mounting shell 503, and quick locking can be completed by the spring pin. Through the cooperation of the spring pin and the pin holes 502, the rotation angle of the box-shaped component can be quickly positioned while the support plate 402 is locked, so as to avoid production line shutdown or personnel injury caused by the box-shaped component falling.
