Abstract
Description
Technical Field
[0001] This utility model relates to the field of stacking equipment technology, specifically to an anti-collision material stacking device. Background Technology
[0002] In traditional technology, stacking large quantities of goods requires a lot of manpower. With the continuous development of mechanical technology, the emergence of stacking equipment can help workers complete this labor-intensive operation, bringing great convenience to workers and improving work efficiency.
[0003] In existing material stacking devices, when lifting and transporting material boxes, the power unit causes the entire device to move, which can easily cause the material boxes to deviate and collide with the equipment frame, or even fall from the air. In addition, the structure of the lifting components of existing devices is not flexible enough and cannot be changed according to the size of the material boxes, so it cannot provide a reliable lifting effect. Therefore, we propose an anti-collision material stacking device. Utility Model Content
[0004] The technical problem this invention aims to solve is to overcome existing defects and provide an anti-collision material stacking device. This device features clamping components in both horizontal and vertical directions, effectively clamping and fixing material boxes to prevent them from deviating and colliding with the device during transportation and lifting. Furthermore, the top pressure frame can be adjusted according to the lifting height of the material box, maintaining moderate pressure while ensuring its stability. It also includes a reliable lifting device; a servo motor drives the lifting rods to move within a certain angle, allowing the two adjacent lifting rods to be spaced at an appropriate angle based on the size of the material box. The separated lifting rods on both sides form a rhomboid structure, effectively supporting the material box. Sensors at the back ensure the four side clamps are aligned, guaranteeing centered clamping of the material box and ensuring the neatness of each layer of stacked material boxes. This effectively solves the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-collision material stacking device, comprising a vertical sliding column, a cargo support unit, and a compression anti-collision unit;
[0006] Vertical sliding column: There are two on the left and right sides, and the lower end of each vertical sliding column is slidably connected to a longitudinally set slide rail;
[0007] Cargo placement unit: installed between two vertical sliding columns on the left and right;
[0008] The compression anti-collision unit includes a mounting bracket, a crossbeam, a vertical sliding rod, a top pressure bracket, a spring, and a top shell. A vertical mounting bracket is fixedly connected to the upper end and inner side of the two left and right vertical sliding columns. A crossbeam is installed between the two mounting brackets. The left and right ends of the crossbeam are engaged and slidably connected to the vertical sliding grooves inside the mounting brackets. A vertical sliding rod is slidably connected to the middle of the crossbeam. An X-shaped top pressure bracket is fixedly connected to the lower end of the vertical sliding rod, and a spring is fitted on the outer side of the vertical sliding rod. A U-shaped, inverted top shell is fixedly connected to the upper end of the crossbeam at a position corresponding vertically to the vertical sliding rod.
[0009] When the lifting boom raises the material, the X-shaped top pressure frame, under the action of spring one, presses and fixes the material to prevent it from deviating and colliding with the device during transportation and lifting. Furthermore, as the material is lifted, if the pressure on spring one becomes excessive, the vertical sliding rod will displace upwards to avoid damage to the material container due to excessive pressure. As the material height continues to rise, the upper end of the vertical sliding rod will press against the top shell, thereby causing the crossbeam to slide upwards along the mounting bracket. This allows the top pressure frame to adjust its position according to the lifting height of the material container, maintaining moderate pressure while ensuring the material container is firmly secured.
[0010] Furthermore, the compression anti-collision unit also includes a limiting shaft, a second spring, and a limiting block. A vertical limiting shaft is fixedly connected to the vertical sliding groove inside the mounting bracket. The limiting shaft passes through the end of the crossbeam and maintains a sliding connection with the crossbeam. A second spring is fitted on both the upper and lower sides of the crossbeam outside the limiting shaft. A circular limiting block is fixedly connected to the upper end of the vertical sliding rod. The limiting shaft is used for installing the second spring and limiting the crossbeam so that it can only slide vertically. The second spring can reset and center the crossbeam, so that the crossbeam is at the middle height inside the mounting bracket. The limiting block is used to prevent the vertical sliding rod from falling downwards.
[0011] Furthermore, the cargo placement unit includes a ball screw, a lifting plate, locking blocks, lifting rods, and servo motors. A vertical mounting groove is provided on the inner side of the vertical sliding column, and a vertical ball screw is installed inside the groove. A lifting plate is installed at the nut of the ball screw. Two clamping blocks are fixedly connected to the back of the lifting plate, and the two locking blocks are respectively locked onto the upper and lower sides of the ball screw nut. Two upper and lower locking blocks are fixedly connected to the lower end of the inner side of the lifting plate, and two lifting rods are rotatably connected between the two locking blocks. Two servo motors are installed on the upper end of the upper locking block, with the output shafts of the servo motors facing downwards and fixedly connected to the end of the lifting rod that is locked into the locking block. The ball screw drives the lifting plate to move up and down, and the locking blocks are used to install the lifting rods and servo motors. The servo motors can drive the lifting rods to move within a certain angle, allowing the two adjacent lifting rods to be spaced at a suitable angle according to the size of the material box. The separated lifting rods on both sides form a diamond structure, which can effectively support the material box.
[0012] Furthermore, the cargo placement unit also includes side clamps, vertical shafts, sliders, sliding rods, and springs. Each lifting rod has an internal mounting groove that runs through it. A sliding rod is fixedly connected inside the groove. The slider is engaged and slidably connected inside the mounting groove, while maintaining a slidable connection with the sliding rod. The upper end of the slider is fixedly connected to a vertical shaft, which is movably connected to the middle part of the side clamp. When the cargo box is placed on the upper side of the lifting rod, the side clamps are pushed outwards. The vertical shaft allows the side clamps to move around the shaft to adjust their angle. Under the action of the spring, the slider can drive the upper side clamps to clamp the left and right sides of the cargo box, thereby achieving a horizontal clamping effect on the cargo box. This further improves the stability of the cargo box during transportation and lifting, effectively preventing collisions.
[0013] Furthermore, the cargo handling unit also includes a control panel and proximity sensors. A proximity sensor is embedded in the center of the outward-facing side of the side clamps. The control panel is mounted on the outer end of the right vertical sliding column. A digital display screen is located on the upper side of the control panel, and a buzzer is located on the lower side. Control buttons and an emergency stop switch are located in the middle of the control panel. The proximity sensors detect the distance between the side clamps and the vertical sliding column after the lifting boom opens. By ensuring that the data detected by each proximity sensor is consistent, the operator ensures that the side clamps can center-grip the material boxes, thereby ensuring the neatness of each layer of material boxes stacked. The control panel is used to control the start and stop of various electrical devices.
[0014] Furthermore, the cargo handling unit also includes an electric trolley and fixed feet. The electric trolley is installed at the bottom of the vertical sliding column, and a fixed foot is fixedly connected to both the front and rear ends of the slide rail. The fixed feet have an L-shaped structure and bolt holes are provided in the horizontal section. The electric trolley is used to drive the vertical sliding column to move along the slide rail, and the fixed feet are used to install bolts to fix the slide rail.

[0017] 2. It has a reliable lifting device. The servo motor can drive the lifting rod to move within a certain angle, so that the two adjacent lifting rods can be separated at a suitable angle according to the size of the material box. The lifting rods on both sides form a diamond structure, which can effectively support the material box. In addition, the distance between each side clamp and the vertical sliding column can be detected by the sensor.

Detailed Implementation
[0024] 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.
[0025] Please see Figures 1-4 This embodiment provides a technical solution: an anti-collision material stacking device, including a vertical sliding column 1, a cargo holding unit 3, and a pressure-fixing anti-collision unit 4;
[0026] Vertical sliding column 1: There are two, one on the left and one on the right, and the lower end of each vertical sliding column 1 is slidably connected to a longitudinally arranged slide rail 2;
[0027] Cargo placement unit 3: installed between the two vertical sliding columns 1 on the left and right;
[0028] The compression anti-collision unit 4 includes a mounting bracket 41, a crossbeam 43, a vertical sliding rod 45, a top pressure bracket 46, a spring 47, and a top shell 48. The upper ends of the two left and right vertical sliding columns 1 are fixedly connected to the vertical mounting brackets 41 on the inner side. A crossbeam 43 is installed between the two mounting brackets 41. The left and right ends of the crossbeam 43 are locked and slidably connected to the vertical sliding grooves on the inner side of the mounting brackets 41. A vertical sliding rod 45 is slidably connected to the middle of the crossbeam 43. A top pressure bracket 46 with an X-shaped structure is fixedly connected to the lower end of the vertical sliding rod 45. A spring 47 is sleeved on the outer side of the vertical sliding rod 45. A U-shaped and inverted top shell 48 is fixedly connected to the upper end of the crossbeam 43 at a position corresponding to the vertical sliding rod 45.
[0029] When the lifting boom 34 lifts the material, the X-shaped top pressure frame 46, under the action of the spring 47, presses and fixes the material to prevent it from deviating and colliding with the device during transportation and lifting. During the lifting process, as the height increases, if the pressure on the spring 47 becomes too great, the vertical slide bar 45 will move upward to avoid excessive pressure and damage to the material box. As the height of the material continues to rise, the upper end of the vertical slide bar 45 will hit the top shell 48, thereby driving the crossbeam 43 to slide upward along the mounting bracket 41. This allows the top pressure frame 46 to adjust its position according to the lifting height of the material box, maintaining moderate pressure while keeping the material box firmly pressed.
[0030] The compression anti-collision unit 4 also includes a limiting shaft 42, a second spring 44, and a limiting block 49. A vertical limiting shaft 42 is fixedly connected to the vertical sliding groove inside the mounting bracket 41. The limiting shaft 42 passes through the end of the crossbeam 43 and maintains a slidable connection with it. A second spring 44 is fitted onto the outside of the limiting shaft 42, located on both the upper and lower sides of the crossbeam 43. A circular limiting block 49 is fixedly connected to the upper end of the vertical sliding rod 45. The limiting shaft 42 is used for mounting the second spring 44 and limiting the crossbeam 43, allowing it to slide only vertically. The second spring 44 can reset and center the crossbeam 43, placing it at the middle height inside the mounting bracket 41. The limiting block 49 prevents the vertical sliding rod 45 from falling downwards.
[0031] The cargo handling unit 3 includes a ball screw 31, a lifting plate 32, a locking block 33, a lifting rod 34, and a servo motor 35. A vertical mounting groove is provided on the inner side of the vertical sliding column 1. A vertical ball screw 31 is installed inside the groove. The lifting plate 32 is installed at the nut of the ball screw 31. Two clamping blocks are fixedly connected to the back of the lifting plate 32. Two locking blocks 33 are respectively locked on the upper and lower sides of the nut of the ball screw 31. Two locking blocks 33 are fixedly connected to the lower end of the inner side of the lifting plate 32. Two lifting rods 34 are rotatably connected between the two locking blocks 33. Two servo motors 35 are installed on the upper end of the upper locking block 33. The output shaft of the servo motor 35 faces downward and is fixedly connected to the end of the lifting rod 34 that is locked into the locking block 33. The ball screw 31 is used to drive the lifting plate 32 to lift and lower. The locking block 33 is used to install the lifting rod 34 and the servo motor 35. The servo motor 35 can drive the lifting rod 34 to move within a certain angle, so that the two adjacent lifting rods 34 can be separated at a suitable angle according to the size of the material box. The lifting rods 34 separated on both sides form a diamond structure, which can effectively support the material box.
[0032] The cargo placement unit 3 also includes side clamps 36, vertical shafts 37, sliders 38, sliding rods 39, and springs 310. Each lifting rod 34 has an internal mounting groove that runs through the rod. A sliding rod 39 is fixedly connected inside the groove. The slider 38 is engaged and slidably connected inside the mounting groove, while maintaining a slidable connection with the sliding rod 39. The upper end of the slider 38 is fixedly connected to the vertical shaft 37, which is movably connected to the middle part of the side clamps 36. When the cargo box is placed on the upper side of the lifting rod 34, the side clamps 36 are pushed outward. The vertical shaft 37 allows the side clamps 36 to move around the shaft to adjust their angle. Under the action of the springs 310, the sliders 38 can drive the upper side clamps 36 to clamp the left and right sides of the cargo box, thereby achieving a horizontal clamping effect on the cargo box, further improving the stability of the cargo box during transportation and lifting, and effectively preventing collisions.
[0033] The cargo handling unit 3 also includes a control panel 311 and proximity sensors 314. A proximity sensor 314 is embedded in the center of the outward-facing side of the side clamping plate 36. The control panel 311 is mounted on the outer end of the right vertical sliding column 1. A digital display screen is located on the upper side of the control panel 311, and a buzzer is located on the lower side. Control buttons and an emergency stop switch are located in the middle of the control panel 311. The proximity sensors 314 detect the distance between the side clamping plate 36 and the vertical sliding column 1 after the lifting rod 34 is opened. By ensuring that the data detected by each proximity sensor 314 is consistent, the operator ensures that the side clamping plates 36 on both sides can center-grip the material boxes, thereby ensuring the neatness of each layer of material boxes stacked. The control panel 311 is used to control the start and stop of various electrical devices.
[0034] The cargo handling unit 3 also includes an electric trolley 312 and fixed feet 313. The electric trolley 312 is installed at the bottom of the vertical sliding column 1, and a fixed foot 313 is fixedly connected to both the front and rear ends of the slide rail 2. The fixed foot 313 has an L-shaped structure and bolt holes are provided in the horizontal section. The electric trolley 312 is used to drive the vertical sliding column 1 to move along the slide rail 2, and the fixed foot 313 is used to install bolts to fix the slide rail 2.
[0035] The working principle of the anti-collision material stacking device provided by this utility model is as follows: This device has clamping components in both horizontal and vertical directions, which can effectively clamp and fix the material box, preventing the material from deviating and colliding with the device during transportation and lifting. When the lifting rod 34 lifts the material, the X-shaped top pressure frame 46 presses and fixes the material under the action of the spring 47 to prevent the material from deviating and colliding with the device during transportation and lifting. During the lifting process, as the height increases, when the pressure on the spring 47 is too large, the vertical slide rod 45 will move upward to avoid excessive pressure and damage to the material box. As the height of the material continues to rise, the upper end of the vertical slide rod 45 will hit the top shell 48, thereby driving the crossbeam 43 to slide upward along the mounting bracket 41, so that the position of the top pressure frame 46 can be adjusted according to the lifting height of the material box, maintaining moderate pressure while keeping the material box firmly pressed. This device also features a reliable lifting mechanism. A servo motor 35 drives the lifting rods 34 to move within a certain angle, allowing the two adjacent lifting rods 34 to be spaced at appropriate angles according to the size of the material box. The separated lifting rods 34 on both sides form a rhomboid structure, effectively supporting the material box. Sensors detect the distance between each side clamping plate 36 and the vertical sliding column 1. Operators ensure that the data detected by each proximity sensor 314 is consistent, guaranteeing that the side clamping plates 36 can center the material box, thus ensuring the neatness of each layer of stacked material boxes. Furthermore, a limiting shaft 42 is used for installing the second spring 44 and limiting the crossbeam 43, allowing it to slide only vertically. The second spring 44 can reset and center the crossbeam 43, placing it at the middle height inside the mounting bracket 41. A limiting block 49 prevents the vertical sliding rod 45 from falling downwards. When the material box is placed on the upper side of the lifting rod 34, the side clamp 36 will be pushed outward. The vertical shaft 37 allows the side clamp 36 to move around the shaft to adjust the angle. Under the action of the spring 310, the slider 38 can drive the upper side clamp 36 to clamp the left and right sides of the material box, thereby achieving the effect of clamping the material box in the horizontal direction. The electric trolley 312 is used to drive the vertical sliding column 1 to move along the slide rail 2. The fixed foot 313 is used to install bolts to fix the slide rail 2. The control panel 311 is used to control the start and stop of the operation of each electrical device.
[0036] It is worth noting that the input terminals of the servo motor 35, electric trolley 312, and ball screw 31 drive motor disclosed in the above embodiments are all electrically connected to the output terminal of the external power supply through an external control switch group. The servo motor 35, electric trolley 312, and ball screw 31 operate using methods commonly used in the prior art.
