Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a structure for detecting the position of the bucket on a forklift. Background Technology

[0002] A structure for detecting the bucket position of a forklift is installed on the bucket and frame of the forklift. Its main function is to provide accurate bucket position data for forklift operation, helping the driver to grasp the bucket status in real time and avoid problems such as material spillage and equipment collision caused by blind spots or operational errors. At the same time, it provides data support for the automated control of the forklift, improving operation efficiency and safety. It can also be used for on-board monitoring to realize the visual recording of bucket movements and abnormal warnings.

[0003] A structure for detecting the bucket position of a forklift mainly consists of a position sensor, a signal transmission component, a data processing unit, and a fixed support component. The position sensor includes encoders, tilt sensors, or laser rangefinders, which are responsible for collecting real-time information on the bucket's lifting height, tilt angle, and spatial position. The signal transmission component transmits the sensor data stably to the control terminal via cables or wireless modules. The data processing unit analyzes and converts the received signals to generate accurate position parameters. The fixed support component uses brackets, mounting bases, and other structures to ensure that the sensor is securely installed on the bucket, boom, or frame, ensuring stable operation of the detection system under complex working conditions.

[0004] In existing technologies, when using the bucket in telescopic forklifts in construction machinery vehicles, the driver cannot clearly and intuitively see the position of the bucket, which affects work efficiency and easily causes safety hazards. The purpose of this mechanism is to enable the driver to have an intuitive comparative understanding of the position of the bucket when using the forklift, so as to avoid safety hazards caused by inexperienced drivers causing items inside the bucket to fall off during use. Therefore, a structure for detecting the position of the bucket in a forklift is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a structure for detecting the position of the bucket on a forklift, aiming to improve the problem in the prior art where the operator cannot clearly and intuitively see the position of the bucket, which leads to the items falling out of the bucket.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A structure for detecting the position of a forklift bucket includes an indicator support. An indicator shaft is fixedly connected to the inner wall of the indicator support. An indicator pendulum is rotatably connected to the outer wall of the indicator shaft. A weight is fixedly connected to the bottom end of the indicator pendulum. A sliding rod is fixedly connected to the top end of the indicator pendulum. Two indicator positioning screws are fixedly connected to the outer wall of the sliding rod. Two sliding grooves are formed in the inner wall of the indicator support. A recess is formed in the inner wall of the indicator support. A disassembly assembly for easy disassembly of the indicator support is provided on the outer wall of the indicator support.

[0008] As a further description of the above technical solution:

[0009] The disassembly assembly includes a protective shell, the outer walls of the two protective shells are fixedly connected to the outer wall of the indicator support, a damper is fixedly connected to the inner wall of the protective shell, a sliding plate is fixedly connected to the left side of the damper, and a spring is sleeved on the outer wall of the damper.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the sliding rod is slidably connected to the inner wall of the two sliding grooves, and the adjacent sides of the two indicator positioning screws are slidably connected to the outer wall of the indicator support.

[0012] As a further description of the above technical solution:

[0013] Two connecting blocks are fixedly connected to the left side of the first sliding plate, and a second sliding plate is fixedly connected to the left side of the two connecting blocks;

[0014] As a further description of the above technical solution:

[0015] A sliding column is fixedly connected to the left side of the sliding plate 2, and the outer wall of the sliding column is slidably connected to the inner wall of the protective shell.

[0016] As a further description of the above technical solution:

[0017] A button is fixedly connected to the left side of the sliding column, and a trapezoidal block is fixedly connected to the left side of the first sliding plate;

[0018] As a further description of the above technical solution:

[0019] The outer wall of the trapezoidal block is slidably connected to two limiting blocks, and the inner wall of the limiting blocks is fixedly connected to a second sliding groove. The outer wall of the second sliding plate is slidably connected to the inner wall of the two second sliding grooves.

[0020] As a further description of the above technical solution:

[0021] The inner wall of the protective shell is provided with a second groove, and the outer walls of the two limiting blocks are slidably connected to the inner wall of the second groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the weight at the bottom of the indicator pendulum is used to keep it in a vertically downward state by gravity. When the position of the bucket changes, the indicator pendulum will rotate through the indicator shaft, which will drive the sliding rod at the top to slide in the groove. The driver can directly observe the relative position of the pendulum and the indicator positioning screw, so as to intuitively know the tilt angle and lifting status of the bucket. This effectively improves the problem that the driver cannot accurately judge the position of the bucket due to blind spots, reduces the risk of material spillage and equipment collision, and is especially suitable for inexperienced drivers, improving the safety and efficiency of operation.

[0024] 2. In this utility model, when the button is pressed, the sliding column will drive the sliding plate two to move to the right. Through the connecting block, the sliding plate one will compress the damper and the spring. The trapezoidal block will move synchronously and squeeze the limiting block, making them close to each other, thereby releasing the lock on the support and realizing quick disassembly. After the button is released, the spring will reset and drive the components to return to their positions. The limiting block will lock the support again, completing the locking. This structure makes the disassembly and maintenance of the indicator support convenient and efficient, reducing maintenance time and cost. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a structure for detecting the position of a forklift bucket, including an indicator support 1. The indicator support 1 is the basic support component of the entire structure, used for installing and fixing other components. An indicator shaft 2 is fixedly connected to the inner wall of the indicator support 1. The indicator shaft 2 is fixed to the inner wall of the indicator support 1 and provides the axis of rotation for the indicator pendulum 3. The indicator pendulum 3 is rotatably connected to the outer wall of the indicator shaft 2. The indicator pendulum 3 can rotate on its outer wall through the indicator shaft 2 and swings with the change of bucket position. A weight 4 is fixedly connected to the bottom end of the indicator pendulum 3. The weight 4 is fixed to the bottom end of the indicator pendulum 3 and uses gravity to keep the indicator pendulum 3 in a stable downward state so as to accurately reflect the bucket position. A sliding rod 5 is fixedly connected to the top end of the indicator pendulum 3. The sliding rod 5 is fixed to the top end of the indicator pendulum 3 and slides in the slide groove 7 with the swing of the indicator pendulum 3 to transmit position change signals.

[0033] Two indicator positioning screws 6 are fixedly connected to the outer wall of the sliding rod 5. These screws are used to position the sliding rod 5 after it has slid to the appropriate position, ensuring the accuracy of the detection position. Two sliding grooves 7 are formed on the inner wall of the indicator support 1, providing a track for the sliding rod 5 and limiting its sliding direction. A groove 8 is formed on the inner wall of the indicator support 1, which may be used to install other components or achieve specific functions; its specific purpose needs further clarification based on the overall structure. A disassembly assembly for easy removal of the indicator support 1 is provided on the outer wall of the indicator support 1. This assembly allows the indicator support 1 to be easily disassembled. When maintenance or replacement is required, it can be easily and quickly disassembled. The outer wall of the sliding rod 5 is slidably connected to the inner wall of the two slide grooves 7. The outer wall of the sliding rod 5 and the inner wall of the two slide grooves 7 form a sliding connection, allowing the sliding rod 5 to slide smoothly in the slide grooves 7, thereby moving with the swing of the indicator pendulum 3. The adjacent sides of the two indicator positioning screws 6 are slidably connected to the outer wall of the indicator support 1. The adjacent sides of the two indicator positioning screws 6 slide on the outer wall of the indicator support 1. After the sliding rod 5 reaches the designated position, the screws can be tightened to fix it to the outer wall of the indicator support 1. Utilizing the simple principle that gravity is always vertically downward, the center of gravity of the pendulum is always perpendicular to the ground. The operator can directly observe the corresponding state of the other end of the pendulum with the positioning screw, and intuitively understand the position status of the bucket.

[0034] Reference Figure 2 and Figure 4The disassembly assembly includes protective shells 9, which are integral parts of the assembly and protect internal components such as dampers 10 and springs 11. They also provide a mounting base for other components. The outer walls of both protective shells 9 are fixedly connected to the outer wall of the indicator support 1, ensuring a stable connection between the disassembly assembly and the indicator support 1. A damper 10 is fixedly connected to the inner wall of the protective shell 9, acting as a buffer during disassembly to reduce impact and vibration between components. A sliding plate 12 is fixedly connected to the left side of the damper 10, allowing it to move with external force during disassembly, thus influencing other components. A spring 11 is fitted onto the outer wall of the damper 10, providing a restoring force after disassembly to return components such as the sliding plate 12 to their initial position. Two connecting blocks 13 are fixedly connected to the left side of the sliding plate 12. Block 13 is fixed to the left side of sliding plate 12 and is used to connect sliding plate 12 and sliding plate 14 so that they can move synchronously. Sliding plate 14 is fixedly connected to the left side of the two connecting blocks 13. Sliding plate 14 is connected to sliding plate 12 through the two connecting blocks 13 and moves together with sliding plate 12 during disassembly, playing the role of transmitting force. Sliding column 15 is fixedly connected to the left side of sliding plate 14. Sliding column 15 is fixed to the left side of sliding plate 14 and its outer wall slides on the inner wall of protective shell 9 to guide the movement direction of sliding plate 14 and ensure the stability of movement. The outer wall of sliding column 15 is slidably connected to the inner wall of protective shell 9. The outer wall of sliding column 15 and the inner wall of protective shell 9 form a sliding connection, so that sliding column 15 can slide smoothly in protective shell 9, thereby driving sliding plate 14 and other components to move. Button 16 is fixedly connected to the left side of sliding column 15. Button 16 is fixed to the left side of sliding column 15 and is the trigger component for disassembly operation. The operator starts the disassembly of the components by pressing button 16.

[0035] A trapezoidal block 17 is fixedly connected to the left side of sliding plate 12. The trapezoidal block 17, fixed to the left side of sliding plate 12, cooperates with the limiting block 18 during disassembly to achieve locking and unlocking of the disassembly assembly. Two limiting blocks 18 are slidably connected to the outer wall of the trapezoidal block 17. The two limiting blocks 18 slide on the outer wall of the trapezoidal block 17, limiting the movement range of sliding plate 12 through their cooperation with the trapezoidal block 17, ensuring the normal operation of the disassembly assembly. A second sliding groove 19 is fixedly connected to the inner wall of the limiting block 18, providing a sliding track for the outer wall of sliding plate 14, allowing sliding plate 14 to slide smoothly within the second sliding groove 19. The outer wall of sliding plate 14 is slidably connected to... The outer wall of the sliding plate 14 is slidably connected to the inner wall of the two sliding grooves 19, ensuring that the sliding plate 14 will not deviate during movement and will always move along the direction of the sliding grooves 19. The inner wall of the protective shell 9 is provided with a groove 20, which is used to accommodate the limiting block 18, allowing the limiting block 18 to slide within the groove 20. At the same time, the groove 20 provides positioning and guidance for the limiting block 18. The outer walls of the two limiting blocks 18 are slidably connected to the inner wall of the groove 20, allowing the limiting blocks 18 to slide smoothly within the groove 20, thereby achieving the cooperative action with the trapezoidal block 17.

[0036] Working Principle: When the position of the forklift bucket changes, the indicator pendulum 3 rotates within the indicator support 1 via the indicator shaft 2, while the weight 4 at its bottom remains vertically downward due to gravity. Simultaneously, the sliding rod 5 at the top of the indicator pendulum 3 slides synchronously within the groove 7 on the inner wall of the indicator support 1, while the indicator positioning screw 6 on the outer wall of the sliding rod 5 slides along the outer wall of the indicator support 1 until the sliding rod 5 swings to the corresponding position with the pendulum. The driver can visually determine the bucket's tilt angle or lifting status by observing the relative position of the indicator pendulum 3 and the indicator positioning screw 6—for example, when the bucket is tilted, the pendulum remains vertical due to the gravity of the weight 4, and its relative displacement with the positioning screw reflects the bucket's tilt amplitude, thus achieving visual detection of the bucket's position.

[0037] When it is necessary to disassemble the indicator support 1, press button 16 to the right. Button 16 drives sliding plate 14 to move to the right via sliding column 15. Sliding plate 14 pushes sliding plate 12 to compress damper 10 and spring 11 via connecting block 13. At this time, trapezoidal block 17 on the left side of sliding plate 12 moves to the right simultaneously, and the limiting blocks 18 on both sides lose their supporting force. Sliding plate 14 slides in sliding groove 19, causing the two limiting blocks 18 to move closer to each other in the groove 20 of protective shell 9, thus releasing the lock on indicator support 1. The state allows for easy disassembly of the support. When button 16 is released, spring 11 returns to its original position, pushing sliding plate 12 to the left. Sliding plate 12 drives trapezoidal block 17 to press the limit blocks 18 on both sides. The limit blocks 18 slide along groove 20 in a direction away from each other, re-locking the indicator support 1 and completing the locking. Throughout the process, damper 10 can buffer the impact force when pressing, ensuring smooth disassembly. Slide groove 2 19 provides guidance for sliding plate 2 14, ensuring the matching accuracy of limit block 18 and trapezoidal block 17.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
