Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a hoisting device with positioning function and an automated transportation equipment. Background Technology

[0002] In logistics warehousing and industrial production, lifting devices play an irreplaceable role as key equipment for vertical cargo transportation. However, existing lifting devices lack effective positioning and detection mechanisms, making it difficult for operators to accurately determine whether goods are in the correct position. For example, if goods are not fully positioned before entering the lifting device's loading platform, the device may begin lifting, easily causing goods to slip, be damaged, or even lead to safety accidents. Similarly, when goods arrive at a designated floor for unloading, if it's not accurately determined whether the goods have reached the front of the door assembly, the door assembly may open too early or too late, affecting normal unloading and reducing transportation efficiency. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a lifting device with a positioning function. By setting a positioning mechanism, it can accurately detect the position information of the goods and automatically control the opening / closing of the door panel assembly and the lifting and lowering of the loading platform based on the detection results, thereby achieving precise transportation and safe operation of goods and overcoming the shortcomings of traditional lifting devices in terms of goods positioning and control.

[0004] This utility model also proposes an automated transportation device with the above-mentioned lifting device having positioning function.

[0025] Reference Figure 1 and Figure 2 This utility model proposes a lifting device with positioning function, including a frame 100, a loading platform 200 movably connected to the frame 100, a door panel assembly 110, and a positioning mechanism 300. Specifically, the frame 100 serves as the supporting structure for the entire lifting device, providing a mounting base for other components. The loading platform 200 is movably connected to the frame 100 and can move vertically along the frame 100. Its main function is to carry goods and drive the goods to move up and down.

[0026] A door panel assembly 110 is provided on the frame 100, and the door panel assembly 110 can be opened and closed. The loading platform 200 can move to the rear end of the door panel assembly 110. When the door panel assembly 110 is open, goods can enter the loading platform 200 from the door panel assembly 110. When the goods are transported to the designated position, the loading platform 200 moves to the rear end of the door panel assembly 110 and the goods are located at the front end of the door panel assembly 110, the door panel assembly 110 opens, and the goods can be unloaded from the loading platform 200 through the door panel assembly 110.

[0027] The positioning mechanism 300 includes a controller and a first positioning detection element 310 and a second positioning detection element 320 electrically connected to the controller. The first positioning detection element 310 is used to detect whether the goods are located at the front end of the door panel assembly 110. When the goods are lifted and lowered by the loading platform 200 to the designated floor and are ready for unloading, the first positioning detection element 310 detects the position of the goods in real time. Once the goods are detected to have reached the front end of the door panel assembly 110 (i.e., the appropriate unloading position), the first positioning detection element 310 transmits a signal to the controller. After receiving the signal, the controller controls the door panel assembly 110 to open so that the goods can be unloaded smoothly.

[0028] The second positioning detection element 320 is used to detect whether the goods have completely entered the loading platform 200. During the loading process, as the goods gradually enter the loading platform 200, the second positioning detection element 320 continuously monitors the entry of the goods. When it is detected that the goods have completely entered the loading platform 200, the second positioning detection element 320 sends a signal to the controller. After receiving the signal, the controller controls the loading platform 200 to begin lifting and lowering, transporting the goods to the designated height position.

[0029] Understandably, the precise detection of the cargo position by the first positioning detection element 310 and the second positioning detection element 320 effectively prevents lifting operations from being performed before the cargo has fully entered the loading platform 200, and prevents the door panel assembly 110 from opening before the cargo has reached the appropriate unloading position. This significantly reduces the risk of cargo slippage and damage, ensuring the safety of the cargo transportation process. Furthermore, the positioning mechanism 300 achieves automatic detection of the cargo position and automated control of the door panel assembly 110 and the loading platform 200. This eliminates the need for frequent manual judgment of cargo position and operation of control buttons, reducing manual intervention and operation time, and improving the efficiency and accuracy of cargo transportation. It can meet the high-efficiency transportation needs in logistics warehousing and industrial production.

[0030] It should be noted that the lifting device with positioning function proposed in this utility model can adapt to the transportation of goods of different sizes and shapes. As long as the goods can be accurately detected in position by the first positioning detection element 310 and the second positioning detection element 320 during transportation, precise transportation can be achieved. At the same time, the automated control method reduces the impact of human factors on the operation of the device and improves the reliability and stability of the device.

[0031] In some embodiments, firstly, the frame 100 is fixedly installed in a suitable position to ensure its stability and verticality. Then, the loading platform 200 is movably connected to the frame 100 via guide rails, pulleys, or other structures, allowing the loading platform 200 to smoothly move up and down vertically along the frame 100. Next, a door panel assembly 110 is installed on the frame 100. The door panel assembly 110 can be opened / closed by a motor drive, cylinder push, or other means. Then, a first positioning detection element 310 and a second positioning detection element 320 are installed. The first positioning detection element 310 can be a photoelectric sensor, proximity switch, etc., and is installed at a suitable position near the front end of the door panel assembly 110 to ensure accurate detection of whether the goods have reached the front end of the door panel assembly 110. The second positioning detection element 320 can also be a photoelectric sensor or proximity switch, installed inside or at the edge of the loading platform 200 to detect whether the goods have completely entered the loading platform 200. The first positioning detection element 310 and the second positioning detection element 320 are electrically connected to a controller via wires.

[0032] Optionally, the controller can be a programmable logic controller (PLC), which has powerful logic control capabilities and stability. The input ports of the controller are connected to the signal output terminals of the first position detection element 310 and the second position detection element 320, respectively, and the output ports of the controller are connected to the drive device (such as a motor controller) of the door panel assembly 110 and the drive device (such as a lifting motor controller) of the loading platform 200, respectively.

[0033] When loading goods is required, the loading platform 200 is in its initial position (usually the bottom). The operator places the goods at the front of the door panel assembly 110 and then pushes the goods to gradually enter the loading platform 200. During the entry process, the second positioning detection element 320 monitors the entry of the goods in real time. When the second positioning detection element 320 detects that the goods have completely entered the loading platform 200, it sends a signal to the controller. Upon receiving the signal, the controller activates the drive mechanism of the loading platform 200, and the loading platform 200 begins to move upwards along the frame 100, transporting the goods to the designated floor.

[0034] Once the loading platform 200 arrives at the designated floor with the goods, it moves to the rear of the door panel assembly 110. At this point, the first positioning detection unit 310 begins detecting whether the goods are located at the front of the door panel assembly 110. With minor adjustments to the loading platform 200 or the natural position of the goods, when the first positioning detection unit 310 detects that the goods have reached the front of the door panel assembly 110, it sends a signal to the controller. Upon receiving this signal, the controller activates the drive mechanism of the door panel assembly 110, opening the door panel assembly 110, allowing the goods to be unloaded from the loading platform 200 through the door panel assembly 110. After unloading, the controller closes the door panel assembly 110, and the loading platform 200 can return to its initial position to prepare for the next goods transport.

[0035] In some embodiments, the first positioning detection element 310 is directly fixed to a suitable position, such as the side or top of the door panel assembly 110, using bolts, clips, or other connecting components. For example, if the first positioning detection element 310 is a photoelectric sensor, its housing is bolted to the side of the door panel assembly 110, so that the sensor's transmitting and receiving ends face the area where the goods may pass. When the goods move to the front end of the door panel assembly 110, they will block or trigger the sensor, thereby generating a signal. This installation method fixes the relative position of the first positioning detection element 310 and the door panel assembly 110, enabling more accurate detection of the position of the goods relative to the front end of the door panel assembly 110 during the opening / closing process of the door panel assembly 110, and reducing detection errors caused by the movement of the door panel assembly 110.

[0036] In other embodiments, a dedicated bracket is installed on the frame 100 or other fixed structure at the front end of the door panel assembly 110 by means of welding, screw connection, etc., and the first positioning detection element 310 is mounted on the bracket. For example, a small metal bracket is welded to the front of the frame 100, and a proximity switch is mounted on the bracket, so that the sensing surface of the proximity switch faces the path of the goods movement. Setting the detection element directly at the front end of the door panel assembly 110 can more directly detect whether the goods have reached the appropriate position, reduce interference that may be caused by intermediate links, and improve the accuracy and timeliness of detection.

[0037] Reference Figure 1The first positioning detection element 310 is located at the front end of the door panel assembly 110. The mounting bracket 311 is U-shaped, and the positioning sensor 312 is mounted on the top of the mounting bracket 311 and fixed with screws, so that the sensor's detection direction faces the inside of the U-shaped channel. When goods pass through the channel, the positioning sensor 312 can detect the presence of the goods. The U-shaped structure provides a relatively regular moving channel for goods, while facilitating the installation and debugging of the positioning sensor 312, enabling the positioning sensor 312 to accurately detect goods from above or the side, thus improving the reliability of the detection. Optionally, the positioning sensor 312 can also be fixed to the side of the mounting bracket 311. It should be noted that when installed at the top, it can detect the overall passage of goods, which is suitable for detection scenarios where there are certain requirements for the height of goods; when installed on the side, it detects the side of the goods, which can more accurately determine whether the goods have reached the designated position and is not affected by the height of the goods.

[0038] In other embodiments, two metal rods of suitable length and diameter are selected and fixed parallel to each other on a horizontal plane by welding or bolting to form a channel for goods movement. A position sensor 312 is mounted on the side of the rod, for example, by welding a small sensor mounting base to the side of the rod and mounting the position sensor 312 on the mounting base, so that the sensor's detection light can cover the channel area.

[0039] In some embodiments, one or more second positioning detection elements 320 are provided and connected to the frame 100: If one second positioning detection element 320 is provided, a key position corresponding to the position of the door panel assembly 110 is selected on the frame 100, such as the middle of the side of the frame 100, and the second positioning detection element 320 is fixed at this position by bolts. If multiple second positioning detection elements 320 are provided, multiple mounting points are evenly distributed on the frame 100 according to the size and shape of the door panel assembly 110, and the second positioning detection elements 320 are installed at each mounting point to ensure that the position status of the door panel assembly 110 can be comprehensively detected. Connecting the second positioning detection elements 320 to the frame 100 can utilize the stability of the frame 100 to ensure the accuracy of the detection, and the setting of multiple second positioning detection elements 320 can detect the door panel assembly 110 from different positions, improving the comprehensiveness and reliability of the detection.

[0040] In other embodiments, a second positioning detection element 320 is provided and connected to the loading platform 200: a suitable position is selected on the loading platform 200, such as the middle of the edge of the loading platform 200, and the second positioning detection element 320 is fixed at this position by welding or bolting, so that it corresponds to the position of the door panel assembly 110. The second positioning detection element 320 provided on the loading platform 200 can more directly detect the position information of the door panel assembly 110 related to the loading platform 200. The provision of a single detection element simplifies the structure and reduces costs while meeting the detection requirements.

[0041] Reference Figure 1 and Figure 2 The second positioning detection element 320 is connected to the loading platform 200 and includes a limiting plate 321 and a contact sensor. When the end of the goods abuts against the limiting plate 321, the goods are fully inserted into the loading platform 200, and the controller receives the signal from the contact sensor. Specifically, the limiting plate 321 is designed to a suitable size and shape, such as a rectangle, according to the size and shape of the goods. The contact sensor is prepared and installed at a suitable position on the limiting plate 321. For example, a mounting hole is made at the center of the surface of the limiting plate 321 that contacts the goods. The contact sensor is embedded in the mounting hole and fixed with glue or bolts. The limiting plate 321 is fixed to the loading platform 200 by welding or bolting to ensure that when the end of the goods abuts against the limiting plate 321, the goods can be fully inserted into the loading platform 200. At the same time, the contact sensor is connected to the controller through a wire so that the controller can receive the signal from the contact sensor.

[0042] Understandably, through the combination of the limit plate 321 and the contact sensor, when the goods fully enter the loading platform 200 and abut against the limit plate 321, the contact sensor can promptly transmit a signal to the controller, thereby accurately determining whether the goods are in place, providing a reliable basis for subsequent lifting operations, avoiding operational errors caused by the goods not being in place, and improving the safety and working efficiency of the lifting device.

[0043] Reference Figure 2 Specifically, the limiting plate 321 is vertically welded to the surface of the loading platform 200 to ensure that the perpendicularity between the limiting plate 321 and the surface of the loading platform 200 meets the requirements. Based on the size of the limiting plate 321 and the stress conditions, a suitable number and length of reinforcing rods 322 are selected. One end of each reinforcing rod 322 is welded to the limiting plate 321, and the other end is welded to the loading platform 200, so that the reinforcing rods 322 are arranged at an angle, forming a triangular structure to enhance the stability of the limiting plate 321. The triangular structure formed by the reinforcing rods 322 effectively enhances the strength and stability of the limiting plate 321, preventing deformation or damage to the limiting plate 321 when goods come into contact with it, ensuring that the limiting plate 321 can accurately restrict the position of the goods, and improving the reliability of the lifting device.

[0044] In other embodiments, during the manufacturing of the loading platform 200, the limiting plate 321 is integrally formed with the loading platform 200 through processes such as casting or injection molding, ensuring that the limiting plate 321 is perpendicular to the surface of the loading platform 200. The integral forming of the limiting plate 321 with the loading platform 200 reduces the number of parts and installation steps, improving production efficiency. Simultaneously, the integrally formed structure provides a more robust connection, eliminating gaps and improving overall aesthetics and sealing.

[0045] Furthermore, to ensure the stability of the goods placed on the loading platform 200, limiting and anti-sway components are installed at the edges or appropriate locations of the loading platform 200. For example, limiting blocks are installed as limiting and anti-sway components at the center of the four sides of the loading platform 200 by means of bolt connection or welding, so that the limiting blocks can abut against the double or multiple outer walls of the goods.

[0046] In other embodiments, anti-sway components are installed on the frame 100 at positions corresponding to the cargo. For example, adjustable limit rods are provided around the inner perimeter of the frame 100. By adjusting the position of the limit rods, they can abut against the outer walls of the cargo on both sides or multiple sides, limiting the cargo from swaying or falling off. By installing anti-sway components on the loading platform 200 or the frame 100, the swaying or falling off of the cargo during the lifting process can be effectively limited, ensuring stable transportation of the cargo and avoiding safety accidents and equipment damage caused by cargo swaying or falling off, thus improving the safety and reliability of the lifting device.

[0047] In a specific embodiment, the limiting and anti-sway assembly includes four limiting plates disposed around the frame 100. The size and shape of the limiting plates can be designed according to the size and shape of the goods, such as an L-shape. Mounting holes are made at appropriate locations around the frame 100 (such as near the four corners), and the four limiting plates are respectively fixed to the mounting holes of the frame 100 with bolts, allowing the limiting plates to abut against the two or more outer walls of the goods. The four limiting plates limit the movement of the goods from around the frame 100, comprehensively restricting the swaying of the goods and ensuring their stability during lifting. This layout is simple in structure and easy to install.

[0048] In other embodiments, the limiting and anti-sway assembly includes four limiting protrusions 210 connected to the loading platform 200. The four limiting protrusions 210 are designed with suitable shapes and sizes, such as rectangular protrusions. Mounting slots are formed at the four corners of the loading platform 200 surface, and the four limiting protrusions 210 are inserted into these slots and fixed by welding or bolting, allowing the limiting protrusions 210 to abut against the goods and prevent them from detaching. The four limiting protrusions 210, arranged at the four corners of the loading platform 200 surface, can limit the goods from multiple directions, effectively preventing them from detaching from the loading platform 200. This arrangement does not occupy excessive space and does not affect the loading and unloading of goods.

[0049] Reference Figure 1 The lifting device proposed in this utility model also includes a drive mechanism 400, which is mounted on the frame 100. The drive mechanism 400 includes a drive component 410 and a movable component 420 connected to the output end of the drive component 410. The movable component 420 is connected to the loading platform 200 and drives the loading platform 200 to rise and fall. In specific applications, the drive mechanism 400 is mounted on the frame 100, and the drive component 410, such as a motor, is installed at a suitable position on the top or side of the frame 100. The movable component 420 is fabricated, such as a chain, lead screw, or wire rope. One end of the movable component 420 is connected to the output end of the drive component 410, for example, by winding a chain around the sprocket of the motor, or by connecting the lead screw to the shaft of the motor via a coupling. The other end of the movable component 420 is connected to the loading platform 200, for example, by fixing the other end of the chain to the top of the loading platform 200, or by passing the lead screw through a threaded hole on the loading platform 200 and threadedly connecting it to the loading platform 200. When the drive component 410 is working, it drives the lifting platform 200 to rise and fall via the movable component 420. The lifting and falling of the lifting platform 200 is achieved through the drive mechanism 400, which can precisely control the position and movement speed of the lifting platform 200 to meet the lifting needs of goods of different heights, improve the automation level and working efficiency of the lifting device, and at the same time, the drive mechanism 400 has a relatively simple structure and is easy to maintain and operate.

[0050] Furthermore, for the safety of cargo transportation, the lifting device also includes a fall arrestor 500. Specifically, a brake rail is installed on the frame 100. Based on the size and range of motion of the loading platform 200, a brake rail of appropriate length and specifications is selected and fixed to a suitable position on the side or inside of the frame 100 by bolts or welding. A safety clamp 510 is connected to the loading platform 200, installed on the side or bottom of the loading platform 200, ensuring that the safety clamp 510 can engage with the brake rail in the event of a stall and fall of the loading platform 200. For example, the safety clamp 510 is fixed to the loading platform 200 by bolts, and the jaws of the safety clamp 510 can make tight contact with the brake rail. When the loading platform 200 stalls and falls, the safety clamp 510, under the action of inertia or other triggering mechanisms, engages with the brake rail, causing the loading platform 200 to brake suddenly. The anti-fall mechanism 500 can quickly brake the loading platform 200 in emergency situations such as a sudden drop, preventing serious safety accidents, ensuring the safety of equipment and personnel, and improving the safety and reliability of the lifting device. It is an important safety protection device in the lifting device.

[0051] Reference Figure 1 The door panel assembly 110 includes a first protective door 111 and a second protective door 112. The first and second protective doors 111 and 112 are arranged vertically and mounted on the frame of the lifting device via hinges or guide rails, allowing them to slide open and close. Simultaneously, two first positioning detection elements 310 are installed at positions at the front ends of the first and second protective doors 111 and 112, respectively, to detect whether the goods are located at the front ends of the first and second protective doors 111 and 112. For example, the first positioning detection elements 310 can be bolted to a bracket at the front end of the protective doors. By arranging the first and second protective doors 111 and 112 vertically and installing the first positioning detection elements 310 at their front ends, the position of the goods at different heights can be detected more accurately, meeting the lifting needs of goods at different levels and improving the flexibility and applicability of the lifting device. Furthermore, the two first positioning detection elements 310 can cooperate to improve the accuracy of the detection.

[0052] Reference Figure 1 and Figure 3This utility model also proposes an automated transportation device, including a lifting device with positioning function as described in any of the preceding claims. Simultaneously, a hidden AGV transport vehicle 600 is introduced, and a travel track or navigation marker for the hidden AGV transport vehicle 600 is set near the loading platform 200 of the lifting device. Through programming control, the hidden AGV transport vehicle 600 travels along a preset path to the loading platform 200, retrieves goods, and moves the goods in and out of the loading platform 200. For example, in a logistics warehouse, the lifting device is installed on the vertical transport channel of the warehouse, and the hidden AGV transport vehicle 600 travels on the warehouse floor, accurately reaching the loading platform 200 through laser navigation or magnetic strip navigation to complete the loading and unloading of goods. This automated transportation device combines a lifting device with positioning function and a hidden AGV transport vehicle, achieving seamless integration of automated vertical and horizontal transportation of goods. It improves the automation level and efficiency of goods transportation, reduces manual operation, lowers labor intensity and human error, and is suitable for large-scale, high-efficiency logistics transportation scenarios.

[0053] Reference Figure 3 Specifically, the submersible AGV transport vehicle 600 includes a vehicle body 610, with a lifting frame 620 mounted on top of the vehicle body 610. The lifting frame 620 can be raised and lowered hydraulically or electrically. A transfer vehicle is manufactured, including a frame 710 and casters 720 connected to the bottom of the frame 710. One or more positioning pins 621 are installed on the lifting frame 620, and one or more positioning slots are formed at corresponding positions on the bottom of the frame 710. When the submersible AGV transport vehicle 600 arrives at the loading platform 200, the transfer vehicle is placed under the lifting frame 620. The lifting frame 620 rises to abut against the bottom wall of the frame 710, and simultaneously, the positioning pins 621 insert into the positioning slots, achieving precise positioning and lifting of the transfer vehicle. Then, the submersible AGV transport vehicle 600 moves the transfer vehicle and the goods. The cooperation of the positioning pins 621 and the positioning slots ensures precise positioning of the submersible AGV transport vehicle 600 when lifting the transfer vehicle, avoiding problems such as goods tilting or falling due to positional deviations. It improves the stability and safety of cargo transportation, while the 720 omnidirectional wheel design allows the transfer vehicle to move flexibly, facilitating the loading, unloading and transportation of goods.

[0054] Reference Figure 2 and Figure 3In a specific embodiment, four limiting protrusions 210 are installed on the surface of the loading platform 200. The distance between the four limiting protrusions 210 is adjusted to be greater than the width of the submersible AGV transport vehicle 600. When the submersible AGV transport vehicle 600 enters the loading platform 200, it accurately travels to the designated position through the navigation system. Then, the lifting frame 620 descends and places the transfer vehicle on the loading platform 200, with the casters 720 abutting against the surface of the loading platform 200. At this time, the four limiting protrusions 210 abut against the casters 720 of the transfer vehicle, restricting the horizontal movement of the transfer vehicle and preventing it from detaching from the loading platform 200. This structure, by limiting the casters 720 of the transfer vehicle with the limiting protrusions 210, effectively prevents the transfer vehicle from detaching from the loading platform 200 due to inertia or other reasons after the AGV transport vehicle enters the loading platform 200 and is placed, improving the stability and safety of the goods transportation process and ensuring the normal operation of the automated transportation equipment.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
