Description

Technical Field

[0001] This utility model belongs to the field of material transfer equipment, specifically a material anti-tipping transfer device. Background Technology

[0002] Material transfer devices are specialized equipment used to handle, transport, or temporarily store materials in different scenarios. Their core functions are to improve transportation efficiency, reduce manual labor intensity, and ensure the safety and stability of materials during the transfer process. Material drums are storage tools for liquids such as oil and paint. When handling material drums filled with paint, transfer equipment must be used.

[0003] According to Chinese Patent Application No. 202420745750.0, a paint bucket transfer device is disclosed, including a support frame and rollers. Rollers are movably installed on the rear two side surfaces of the support frame and located below. A shovel plate is fixedly installed on the lower front surface of the support frame. Vertical rods are fixedly installed on the inner two side surfaces of the support frame. A limit rod is movably installed on one side surface of the upper end of the vertical rod. A foot pedal is movably installed between the vertical rods. When the foot pedal is pressed down, the foot pedal will drive the gear of the limit rod to rotate. During the rotation of the gear, the limit rod will rotate upward. After the limit rod rotates, it can push the support frame and scoop up the paint bucket. When the support frame is tilted, the external force of pressing the foot pedal is released. At this time, the torsion spring will cause the limit rod to rotate back to its original position, thereby using the limit rod to limit the paint bucket and prevent the paint bucket from falling during the movement of the support frame.

[0004] Existing technology effectively solves the problem that the transfer device is inconvenient to fix the material bucket and is prone to tipping during transfer. It has the advantage of convenient fixing and limiting the material bucket. However, the material bucket is clamped and fixed by the preload of the torsion spring. When the torsion spring is subjected to external force, it is easy to deform, which can easily cause the material bucket to loosen and thus affect the stable transfer of the material bucket.

[0005] In summary, this utility model provides a material anti-tipping and transfer device to solve the above problems. Utility Model Content

[0013] Beneficial effects: This utility model has the following beneficial effects:

[0014] This invention utilizes a parallel component within a fixed assembly, employing a cylinder to drive a connecting plate, which in turn rotates a gear, causing a rack meshing with the gear to move linearly. This enables the parallel movement of the clamping plate, allowing for flexible adjustment based on the size of the material bucket and ensuring a tight grip. A limiting component further enhances the stability of the clamping plate's movement. The cooperation between the slide rail and slide block makes the movement of the support plate smoother.

[0022] Example 1

[0023] like Figure 1-4 The first embodiment of this utility model is shown, which provides a material anti-tipping transfer device, including a transfer assembly 100, comprising a base 110, a gantry frame 120 fixed to the top of the base 110, casters 130 fixed to the rear end of the bottom of the base 110, auxiliary wheels 140 fixed to the front end of the bottom of the base 110, and a handle 150 fixed to the surface of the gantry frame 120; a lifting assembly 200, comprising a ball screw 210, a ball nut 220 sleeved on the surface of the ball screw 210, a servo motor 230 and a reducer 240 fixed to the top of the gantry frame 120, a slide groove 250 formed on the side of the gantry frame 120, a sliding sleeve 260 slidably connected to the surface of the gantry frame 120, and a limiting wheel 270 slidably connected to the inner cavity of the slide groove 250; and a fixing assembly 300. The system includes a clamping plate 310, a support base 320 fixed to the surface of the sliding sleeve 260, a support frame 330 fixed to the surface of the support base 320, a bottom plate 340 fixed to the bottom of the support base 320, a parallel assembly 350 installed in the inner cavity of the support base 320 and the support frame 330, and a limiting assembly 360 fixed to the surface of the support frame 330. The clamping plate 310 consists of two clamping plates. The parallel assembly 350 includes a cylinder 351, a connecting plate 352 fixed to the output end of the cylinder 351, a gear 353 installed in the inner cavity of the support frame 330 via a bearing, a rack 354 meshing with the upper and lower ends of the support frame 330, a transition block 355 fixed to the surface of the rack 354, and a support plate 356 fixed to the surface of the transition block 355. One end of the clamping plate 310 is fixedly connected to the support plate 356.

[0024] like Figure 1-4As shown, the transfer assembly 100 is the basic moving part of the device. The base 110 provides support for the entire device. Casters 130 are installed at the rear bottom of the base 110, and auxiliary wheels 140 are installed at the front bottom of the base 110. Workers push or pull the device by gripping the handles 150 on the surface of the gantry frame 120. The casters 130 and auxiliary wheels 140 work together to allow the device to move flexibly, realizing the transfer of the material bucket between different positions. The parallel assembly 350 is driven by a cylinder 351. The output end of the cylinder 351 pushes the connecting plate 352, which in turn moves the connected support plate 356. The support plate 356 is fixedly connected to the clamping plate 310, thereby clamping the material bucket. Compared to a torsion spring, the cylinder 350... The driving force of component 51 is stable and precisely controllable, providing a continuous and stable clamping force for the bucket, preventing loosening due to external forces. The lifting component 200 can adjust the height of the bucket as needed. Driven by the ball screw 210 and ball nut 220, and driven by the servo motor 230 and reducer 240, stable and precise lifting action can be achieved. At the same time, the limiting wheel 270 slides in the slide groove 250, which limits and guides the movement of the sliding sleeve 260, thereby ensuring the smoothness of the lifting process. Through the synergistic effect of the parallel component 350, the limiting component 360 and the lifting component 200, the loosening problem that easily occurs when the torsion spring preload clamps and fixes the bucket can be effectively solved, ensuring the stable transfer of the bucket.

[0025] Example 2

[0026] Reference Figure 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, the limiting component 360 includes a slide rail 361, a slide block 362 slidably connected to the surface of the slide rail 361, and a guide wheel 363 mounted in the inner cavity of the support frame 330 via a bearing. The end of the slide block 362 away from the slide rail 361 is fixedly connected to the support plate 356. There are two support plates 356, which are located at both ends of the surface of the support frame 330.

[0028] The limiting component 360 includes a slide rail 361, a slide block 362 slidably connected to the surface of the slide rail 361, and a guide wheel 363 mounted in the inner cavity of the support frame 330 via a bearing. The end of the slide block 362 away from the slide rail 361 is fixedly connected to the support plate 356. There are two support plates 356, which are located at both ends of the surface of the support frame 330.

[0029] Two sets of cylinder 351 and connecting plate 352 are provided. The end of connecting plate 352 away from cylinder 351 extends through the inner cavity of support frame 330 and is fixedly connected to support plate 356. Cylinder 351 is fixed to the inner cavity of support seat 320.

[0030] One end of the ball screw 210 is movably connected to the base 110 via a bearing. The ball nut 220 is threadedly connected to the ball screw 210 and is fixedly connected to the support base 320. The output shaft of the servo motor 230 is drivenly connected to the input shaft of the reducer 240, and the output shaft of the reducer 240 is drivenly connected to the other end of the ball screw 210.

[0031] The limiting wheel 270 is movably connected to the sliding sleeve 260 via a bearing. The limiting wheel 270 extends into the inner cavity of the sliding groove 250 and is slidably connected to the inner cavity of the sliding groove 250.

[0032] like Figure 1-4 As shown, the limiting component 360 further enhances the stability of clamping. The cooperation of the slide rail 361 and the slide block 362 guides and limits the movement of the support plate 356, ensuring that the clamping plate 310 maintains linear motion during the clamping of the bucket, avoiding wobbling or deviation. The guide wheel 363 contacts the rack 354, which helps to ensure the stability of the transmission, enabling the clamping plate 310 to clamp the bucket more accurately and reducing the possibility of the bucket becoming loose due to external interference. The slide rail 361 is fixed to the surface of the support frame 330, and the slide block 362 slides on the slide rail 361 and is fixedly connected to the support plate 356. The guide wheel 363 contacts the rack 354, guiding the movement of the rack 354 and ensuring that the clamping plate 310 moves smoothly during the movement. For stability and accuracy, the lifting assembly 200 is used to lift the material bucket. After the servo motor 230 starts, its output shaft drives the input shaft of the reducer 240 to rotate. After the reducer 240 reduces speed and increases torque, the output shaft of the reducer 240 drives the ball screw 210 to rotate. Since the ball nut 220 is threadedly connected to the ball screw 210 and fixedly connected to the support seat 320, when the ball screw 210 rotates, the ball nut 220 will move linearly along the ball screw 210, thereby driving the support seat 320 to move up and down. At the same time, the sliding sleeve 260 slides on the surface of the gantry frame 120, and the limit wheel 270 slides in the slide groove 250, playing a limiting and guiding role, ensuring that the support seat 320 lifts and lowers smoothly, thereby ensuring that the material bucket lifts and lowers smoothly.

[0033] In use, first, move the device to the material bucket placement position, start the cylinder 351 of the parallel component 350, so that the two clamping plates 310 move in parallel and clamp the material bucket. When the cylinder 351 works, its output end pushes the connecting plate 352 to move. The connecting plate 352 drives the support plate 356 to move. The support plate 356 is connected to the rack 354 through the adapter block 355, so that the rack 354 moves. Since the rack 354 meshes with the gear 353, the two racks 354 move synchronously in opposite directions under the action of the gear 353, so that the two clamping plates 310 can move in parallel and can stably clamp the material bucket. At the same time, the bottom plate 340 supports the material bucket and prevents the material bucket from tipping over. The rear caster 130 and the front auxiliary wheel 140 facilitate the movement of the device. By holding the handle 150 on the surface of the gantry frame 120 to push or pull the device, the material bucket can be transferred.

[0034] After the servo motor 230 starts, its output shaft transmits power to the reducer 240. The reducer 240 adjusts the speed of the motor to output power to the ball screw 210 with appropriate torque and speed. The ball screw 210 is threadedly connected to the ball nut 220. When the ball screw 210 rotates, the ball nut 220 will move linearly along the ball screw 210. Since the ball nut 220 is fixedly connected to the support base 320, the support base 320 will move up and down with the movement of the ball nut 220, thereby raising the material bucket to a suitable position.
