Description

Technical Field

[0001] This utility model relates to a vehicle positioning mechanism, and more particularly to a vehicle guidance and positioning device for a workshop. Background Technology

[0002] In workshop production operations, transport vehicles are the core equipment for material transfer, and their precise guidance and stable positioning directly affect production efficiency, operational safety, and the accuracy of process connections. Currently, the commonly used positioning methods for transport vehicles in workshops mostly rely on manual visual alignment, simple mechanical limiters, or traditional sensor-triggered positioning, which have many shortcomings.

[0003] Traditional manual positioning methods rely on operator experience, which is not only inefficient but also prone to positioning deviations due to human error. This can affect the accuracy of subsequent processes such as material loading, unloading, and assembly, increasing production losses. Simple mechanical limit devices lack flexible guiding structures, making them prone to deviation and jamming during transport vehicle movement. Furthermore, the limit components are easily deformed and damaged after long-term impact, resulting in high maintenance frequency and short service life.

[0004] Furthermore, the components of existing positioning devices lack sufficient stability, and are prone to loosening and displacement after long-term use, further reducing positioning reliability and failing to meet the needs of large-scale production and high-precision operations in workshops. Therefore, there is an urgent need for a workshop transport vehicle guiding and positioning device with precise guidance, stable locking, collision protection, and a reliable structure to overcome the shortcomings of existing technologies.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a workshop transport vehicle guidance and positioning device, which would have greater industrial application value. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a guide and positioning device for transport vehicles in a workshop.

[0007] This utility model discloses a guide and positioning device for a transport vehicle in a workshop, including a base plate installed on a foundation, a support frame installed in the middle of the base plate, a tray bracket fixed to the top of the support frame by bolts, a rotatable tray mounted inside the tray bracket via a shaft, and a hook at the front end of the tray for locking the transport vehicle by gripping the bottom of the transport vehicle.

[0008] This type of in-workshop transport vehicle guiding and positioning device has a base plate installed on the foundation. The support frame installed in the middle of the base plate provides stable support for the overall structure. The top of the support plate is fixed with bolts to the tray bracket. The tray bracket is equipped with a shaft to enable the flexible rotation of the tray plate. The hook at the front end of the tray plate can accurately engage the bottom of the transport vehicle, thereby reliably completing the positioning and locking of the transport vehicle and ensuring the stability of the transport vehicle during subsequent operations.

[0009] Furthermore, a forward-moving cylinder bracket is installed on the inner bottom of the support frame. The cylinder bracket is movably connected to the tail end of the cylinder via a shaft, and the telescopic rod of the cylinder is movably connected to the tail end of the support plate via a shaft.

[0010] The cylinder bracket mounted on the inner bottom of the support frame is in a forward-raised state, providing a stable mounting base for the cylinder. The tail end of the cylinder is flexibly connected to the cylinder bracket via a shaft, and its telescopic rod is linked to the tail end of the pallet via a shaft connection, which can drive the pallet to rotate smoothly, thereby providing power support for the hook to lock the transport vehicle.

[0011] Furthermore, the surface of the pallet has a recessed mounting groove on the rear side of the hook, which is used to mount a proximity sensor.

[0012] The pallet surface has a recessed mounting groove near the rear of the hook. This mounting groove is specifically designed to house a proximity sensor, which allows the sensor to accurately detect the arrival status of the transport vehicle, providing reliable signal support for triggering subsequent locking actions and ensuring the automated connection of the positioning process.

[0013] Furthermore, vertically upward-facing supports are fixed on both sides of the base plate, and forward-protruding anti-collision blocks are fixed to the upper surface of the supports by bolts.

[0014] Vertical supports are fixed on both sides of the base plate. The upper surface of the supports is bolted with forward-protruding anti-collision blocks. These anti-collision blocks can buffer and protect the transport vehicle when it approaches, preventing the transport vehicle from colliding directly with the supports and causing damage, thus enhancing the overall durability and safety of the device.

[0015] Furthermore, a reinforcing plate is fixed to the inner side of the upper end of the support frame by bolts.

[0016] The upper inner side of the support frame is fitted with a reinforcing plate by bolts, which can effectively enhance the structural strength and stability of the support frame, prevent the support frame from deforming after long-term stress or impact, and further ensure the overall stability and service life of the device.

[0017] Furthermore, guide plates are bolted to the outside of the support frame.

[0018] Guide plates are bolted to the outside of the frame, which can play a precise guiding role during the movement of the transport vehicle, guiding the transport vehicle to approach the positioning position along the correct path, avoiding deviation from the positioning effect and improving the smoothness of the positioning process.

[0019] Furthermore, the front end of the guide plate extends outward.

[0020] The front end of the guide plate expands outward, which increases the initial guidance range for the transport vehicle. Even if the transport vehicle deviates to some extent while driving, it can be successfully guided into the correct path, further improving the fault tolerance and accuracy of the guidance, and ensuring that the transport vehicle steadily approaches the positioning area.

[0021] By means of the above-described solution, the present invention has at least the following advantages: 1. Precise and efficient guidance with strong fault tolerance: The outward expansion structure of the front end of the guide plate expands the initial guidance range. Even if the transport vehicle deviates slightly, it can be smoothly guided to the correct path. Combined with the auxiliary limit of the upright, it greatly improves the guidance accuracy and process smoothness, reduces the adjustment time before positioning, and improves the work efficiency.

[0022] 2. Stable and reliable positioning with a high degree of automation: Relying on the linkage structure between the cylinder and the pallet, it can provide stable power for the hook locking action, so that the hook can accurately engage the bottom of the transport vehicle and achieve reliable locking; the mounting slot on the pallet is adapted to the installation of proximity sensors, which can accurately sense the position of the transport vehicle and automatically trigger the locking process, avoiding errors caused by human intervention and ensuring positioning consistency.

[0023] 3. Sturdy and durable structure with low maintenance costs: The combined design of the support frame, uprights and reinforcing plates significantly enhances the overall structural strength and stability of the device, effectively resisting the stress and impact during long-term use, and reducing the risk of component deformation and loosening; the anti-collision blocks on the uprights can buffer the impact force when transport vehicles approach, avoid direct collision damage to the equipment, extend the service life of the device, and reduce maintenance frequency and costs.

[0024] 4. Comprehensive safety protection and wide adaptability: The buffer protection of the anti-collision blocks and the stable locking of the overall structure jointly ensure the safety of personnel and equipment during the positioning of the transport vehicle and subsequent operations, avoiding safety hazards caused by positioning failure; the components of the device are fixed by bolts, making installation and disassembly convenient, adapting to the foundation installation requirements of different workshops, and meeting the needs of large-scale production and high-precision operation scenarios.

Detailed Implementation

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] See Figure 1 When the transport vehicle guiding and positioning device in the workshop is working, the base plate 1 installed on the foundation provides a stable foundation for the overall structure. The support frame 2 in the middle of the base plate 1 provides reliable support for the top pallet bracket 8. The pallet bracket 8 realizes the flexible rotation of the pallet 3 through the shaft. When the transport vehicle arrives at the designated position, the hook 4 at the front end of the pallet 3 can accurately lock onto the bottom of the transport vehicle, thereby completing the stable locking of the transport vehicle. The coordinated cooperation of all components realizes the accurate positioning and reliable fixation of the transport vehicle, avoiding displacement of the transport vehicle during operation and ensuring the smooth progress of subsequent processes. At the same time, the bolt connection method facilitates the installation and maintenance of components, improving the practicality and stability of the device.

[0030] See Figure 1 and Figure 3 The cylinder bracket 5 at the bottom inner side of the support frame 2 is raised forward and provides stable support for the cylinder 6. The tail end of the cylinder 6 is flexibly connected to the cylinder bracket 5 via a shaft. Its telescopic rod is linked to the tail end of the pallet 3 via a shaft connection. During operation, the cylinder 6 drives the telescopic rod to extend and retract, thereby causing the pallet 3 to rotate smoothly around the shaft inside the pallet bracket 8, providing continuous and stable power for the hook 4 to lock the transport vehicle. The linkage between the cylinder 6 and various components realizes the automated drive of the locking action without manual intervention, which not only improves the positioning efficiency, but also ensures the smoothness of the rotation of the pallet 3 and the reliability of the hook 4 locking. At the same time, the shaft connection allows the various components to move flexibly, reduces mechanical wear, and extends the service life of the device.

[0031] See Figure 2The recessed mounting groove 7 on the surface of the pallet 3, located behind the hook 4, is specifically designed to house the proximity sensor. During operation, the proximity sensor continuously senses the arrival status of the transport vehicle. When the transport vehicle reaches the designated position, it immediately sends a signal to the corresponding PLC. The PLC receives the signal, performs logical judgment, and outputs a control command, which in turn controls the cylinder 6 to start working, driving the pallet 3 to rotate and causing the hook 4 to complete the locking action. Through the linkage between the proximity sensor, PLC, and cylinder 6, the positioning and locking process is automated, eliminating the need for manual operation. This improves the accuracy and efficiency of positioning and avoids human error. At the same time, the recessed design of the mounting groove 7 provides a stable installation environment for the proximity sensor, preventing it from being damaged by external interference or collisions, thus ensuring the reliability of signal transmission and the stability of the device operation.

[0032] See Figure 1 , Figure 3 and Figure 4 The vertically upward-facing support frame 9 fixed on both sides of the base plate 1 provides a stable installation foundation for the anti-collision block 10. The anti-collision block 10, which is fixed to the upper surface of the support frame 9 by bolts, will first contact the transport vehicle and play a buffering and deceleration role if the transport vehicle deviates or has excessive inertia during the process of the transport vehicle approaching the positioning position along the guide path. This effectively avoids the transport vehicle directly hitting the support frame 9 and causing equipment damage, and at the same time reduces the impact of the vibration generated by the impact on the positioning accuracy of the device. This not only protects the structural integrity of the support frame 9 and the overall device, but also improves the safety and stability of the transport vehicle during the positioning process and extends the overall service life of the device.

[0033] The reinforcing plate 11, which is fixed to the inner side of the upper end of the upright frame 9 by bolts, fits tightly against the upright frame 9. During operation, it can form a stable overall structure with the upright frame 9, and jointly bear the lateral force, impact force and force transmitted by the anti-collision block 10 that may be generated when the transport vehicle approaches. This significantly enhances the structural strength and deformation resistance of the upright frame 9, and avoids problems such as loosening and bending after the upright frame 9 is subjected to long-term stress or impact. This ensures the installation stability of components such as the anti-collision block 10 and guide plate 12 installed on the upright frame 9, and ensures that each component always maintains a normal working posture, thereby improving the overall structural reliability and service life of the device.

[0034] The guide plate 12, which is fixed to the outside of the upright 9 by bolts, is arranged along the travel path of the transport vehicle. During operation, as the transport vehicle approaches the positioning area, the guide plate 12 will accurately guide the travel direction of the transport vehicle, correct any slight deviations that may occur, and ensure that the transport vehicle always approaches the positioning position of the pallet 3 along the preset path. This greatly reduces the risk of deviation during the transport vehicle's travel, reduces the adjustment steps before positioning, and improves the smoothness and efficiency of the positioning process. At the same time, the bolt fixing method makes the installation and maintenance of the guide plate 12 more convenient, and it can maintain a stable connection with the upright 9, ensuring the reliability of guidance during long-term use and laying a good foundation for the precise locking of the hook 4 in the future.

[0035] The outward-expanding guide plate 12 is installed on the outside of the upright 9. During operation, in the initial stage when the transport vehicle travels towards the positioning area, its outward-expanding structure can expand the guidance coverage. Even if the transport vehicle deviates to a certain extent, it can quickly capture and guide the transport vehicle, gradually correct the driving direction, and ensure that the transport vehicle smoothly approaches the preset positioning path. This significantly improves the fault tolerance and adaptability of the guidance. There is no need for manual assistance to adjust the driving posture of the transport vehicle, which reduces the difficulty of operation. At the same time, it shortens the time for the transport vehicle to approach the positioning position, further improving the efficiency of the positioning process. It can also reduce the hard friction between the transport vehicle and the guide plate 12, ensuring the smoothness of the guidance process and the service life of the guide plate 12, and providing a reliable premise for the subsequent collaborative completion of accurate positioning by various components.

[0036] The working principle of this utility model is as follows: The complete workflow of this device is as follows: After the transport vehicle starts, it travels towards the positioning area. The outward-expanding guide plate 12 at the front end expands the guidance coverage area with its expansion structure, first capturing the transport vehicle and gradually correcting any possible driving deviations. Under the precise guidance of the guide plate 12 on the outer side of the upright 9, the transport vehicle smoothly approaches along the preset path. If deviation or excessive inertia occurs during the journey, the anti-collision block 10 protruding forward on the upper surface of the upright 9 will contact the transport vehicle and play a buffering and deceleration role. At the same time, the reinforcing plate 11 on the inner side of the upper end of the upright 9 enhances the structural strength of the upright 9 and ensures the installation stability of the anti-collision block 10 and the guide plate 12. When the transport vehicle reaches the designated positioning position, the proximity sensor on the surface of the pallet 3, located in the mounting groove 7 behind the hook 4, accurately senses the arrival status of the transport vehicle and immediately sends a signal to the corresponding PLC. After receiving the signal and performing logical judgment, the system outputs a control command to start the cylinder 6 on the cylinder bracket 5 at the bottom inside the support frame 2. The telescopic rod of the cylinder 6 extends and retracts, and is linked to the tail end of the pallet 3 through the shaft, causing the pallet 3 inside the pallet bracket 8 to rotate smoothly around the shaft. Finally, the hook 4 at the front end of the pallet 3 is precisely locked onto the bottom of the transport vehicle. Throughout the process, the base plate 1 provides a stable installation foundation for the overall structure, while the support frame 2 provides reliable support for the pallet bracket 8 and the cylinder bracket 5, ensuring that all components work together to achieve precise positioning and stable locking of the transport vehicle.
