Description

Technical Field

[0001] This utility model relates to the field of rail transport vehicle technology, specifically to an auxiliary positioning device for a heavy-duty RGV mother-daughter vehicle. Background Technology

[0002] In the production process of aluminum sheet and strip processing plants, hot rolling and cold rolling processes are usually distributed across different workshop areas, making the intra-plant logistics transfer of high-temperature aluminum coils a key link affecting production continuity and efficiency. With the country's vigorous promotion of intelligent manufacturing in the non-ferrous metals industry, building efficient and reliable intelligent logistics systems has become one of the core tasks of production line upgrading and transformation. Rail-guided Automated Guided Vehicles (RGVs) are gradually being widely used in workshop material transfer due to their advantages such as fixed paths, high control precision, and strong load-bearing capacity. In recent years, the industry has proposed a heavy-duty RGV system with "mother car-daughter car" collaborative operation. By combining a mother car running on the main track with daughter cars that can run on the mother car and vertically arranged auxiliary tracks, a grid-like transportation network covering multiple areas is constructed to achieve automated loading, unloading, and transfer of aluminum coils.

[0003] However, during track switching operations between the slave car and the mother car—that is, during the transfer of the slave car from the mother car to the ground track or vice versa—it is essential to ensure precise alignment between the slave car track on the mother car and the ground track. Existing technologies largely rely on position sensors to monitor the mother car's status in real time. While this can provide a preliminary assessment of track alignment, it lacks a mechanical locking mechanism for the relative position of the mother car and the ground track. In actual operation, if there is a deviation in track alignment, the slave car is highly susceptible to exerting lateral forces on the mother car during track switching, causing the mother car to deviate. In severe cases, this could lead to derailment of the slave car, resulting in equipment damage or even a safety accident, posing a high risk to the system's operation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an auxiliary positioning device for heavy-duty RGV mother and daughter cars. Through the pre-alignment of the guide plate and the slot and the insertion and cooperation of the positioning rod and the positioning slot, the dual precise positioning of the mother car and the ground track is realized, which effectively avoids the problem of the daughter car running off track or derailing due to track misalignment, thereby avoiding the occurrence of accidents. It has high operational safety and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heavy-duty RGV mother-daughter vehicle auxiliary positioning device, comprising a mother vehicle and a concrete block arranged in the workshop for installing a roll material placement rack.

[0014] 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.

[0015] Please see Figure 1-2 This utility model provides a technical solution: a heavy-duty RGV mother-daughter vehicle auxiliary positioning device, including a mother vehicle 1 and a concrete block 6 arranged in the workshop for installing a roll material placement rack. The mother vehicle 1 is provided with a daughter vehicle track. Two symmetrically arranged preliminary positioning components are provided on the side of the mother vehicle 1. The preliminary positioning components include a guide rail 4 parallel to the daughter vehicle track. A guide plate 42 is slidably arranged on the guide rail 4. A pressure sensor 51 is installed on the side of the guide plate 42 corresponding to the middle of the concrete block 6. A symmetrically arranged slot 61 is opened on the side of the concrete block 6 corresponding to the guide plate 42. A positioning groove 62 is opened in the middle of the side of the concrete block 6 corresponding to the mother vehicle 1. A positioning rod 21 that can be inserted into the positioning groove 62 is slidably arranged on the mother vehicle 1.

[0016] Furthermore, an electric push rod 41 is provided on the guide rail 4. The telescopic end of the electric push rod 41 is connected to the guide plate 42. When the mother car 1 moves forward along its track, the electric push rod 41 on the rear side is extended. The electric push rod 41 pushes the guide plate 42 to move along the guide rail 4. The guide plate 42 drives the pressure sensor 51 set at its front end to move forward synchronously.

[0017] Furthermore, a pad 5 is provided between the guide plate 42 and the pressure sensor 51 to protect the pressure sensor 51.

[0018] Furthermore, a sleeve 2 is provided on the upper surface of the mother car 1 corresponding to the positioning rod 21, and the positioning rod 21 is movably inserted inside the sleeve 2. An electro-hydraulic actuator 3 is provided on the upper surface of the mother car 1 corresponding to the end of the positioning rod 21, and the telescopic end of the electro-hydraulic actuator 3 is fixedly connected to the positioning rod 21. When the electro-hydraulic actuator 3 is activated, it pushes the positioning rod 21 downward, causing it to slowly insert into the positioning groove 62 on the concrete pier 6. During this process, the mother car 1 can move slightly along the track, thereby achieving automatic and precise alignment between the mother car track and the ground track, ensuring that the subcar runs safely and smoothly back and forth between the mother car and the ground.

[0019] Furthermore, the insertion end of the positioning rod 21 is a conical structure, which can improve the fault tolerance rate. After the conical end is inserted into the positioning groove 62, the position of the mother car 1 can be corrected during subsequent insertion.

[0020] The electro-hydraulic actuator 3, electric actuator 41, and pressure sensor 51 used in this invention are all commonly used electronic components in the prior art. Their working methods and circuit structures are known technologies and will not be described in detail here.

[0021] When using: When the mother car 1 moves forward along its track, the electric push rod 41 at the rear of the control extends, and the electric push rod 41 pushes the guide plate 42 to move along the guide rail 4. The guide plate 42 drives the pressure sensor 51 set at its front end to move forward synchronously. When the mother car 1 runs to the position corresponding to the preset concrete block 6, the guide plate 42 is inserted into the slot 61 on the concrete block 6, the pressure sensor 51 is squeezed by the concrete block 6 and generates a signal, at which time the control system immediately commands the mother car 1 to stop running. Subsequently, the electro-hydraulic actuator 3 is activated, pushing the positioning rod 21 downwards so that it slowly inserts into the positioning groove 62 on the concrete pier 6. During this process, the mother car 1 can move slightly along the track, thereby achieving automatic and precise alignment between the mother car track and the ground track, ensuring that the daughter car runs safely and smoothly between the mother car and the ground.

[0022] This utility model achieves precise dual positioning of the mother car 1 and the ground track through the pre-alignment of the guide plate 42 and the slot 61 and the insertion and cooperation of the positioning rod 21 and the positioning slot 62, effectively avoiding the problem of the daughter car running off track or derailing due to track misalignment, thereby avoiding accidents and ensuring high operational safety.
