Description

Technical Field

[0001] The utility model relates to the technical field of logistics devices, in particular to an intelligent logistics device used in steel structure production. Background Art

[0002] Currently, the transportation of steel structure products in steel structure production consumes a lot of manpower, often requiring crane lifting or manual crane movement. However, manual handling is labor-intensive, especially for large and heavy steel structures. Furthermore, crane transfer is difficult, and some steel structures even require two cranes to complete the transfer, resulting in low efficiency.

[0003] In order to solve the above problems, the existing invention patent with publication number CN113978981A discloses a heavy-loaded mother-and-child vehicle, which includes a mother vehicle rolling on a mother track and a child vehicle running on the mother vehicle's auxiliary track and the child vehicles on the child tracks on both sides of the mother track. The mother vehicle is provided with an auxiliary track for the child vehicle to travel. The bottom of the child vehicle is provided with a child vehicle travel motor to drive the child vehicle and the travel wheels running on the auxiliary track on the mother vehicle and the child tracks on both sides of the mother track; both sides of the child vehicle are provided with a lifting screw driven by a single drive motor.

[0004] Although the invention uses a screw jacking device to achieve the rapid lifting of general heavy objects, the bearing capacity of the screw jacking device during the lifting process is mainly concentrated on the screw rod, and the strength of the screw rod is relatively low. Therefore, the screw jacking device cannot quickly lift heavy steel structure products weighing tens of tons and more than 10 meters in length. The screw rod is prone to breakage or deformation, which reduces the safety of steel structure product transportation. At the same time, if a larger lifting height is required using a screw jacking device, there are usually two solutions: 1. Increase the length of the screw rod to obtain a larger lifting height, which will cause a significant increase in the height of the entire trolley, which will in turn affect the height of the working surface of the entire production line, resulting in increased equipment costs and inconvenience in operation; 2. Due to the increase in equipment height, in order to obtain better operational convenience, the height of the equipment working surface can be lowered by digging a pit in the equipment foundation, but this will increase the construction workload of the equipment foundation, making installation and maintenance inconvenient and increasing the cost of the equipment foundation. In addition, the use of a screw jacking device makes the equipment structure more complicated. Due to the harsh environment and high dust content at the steel structure production site, long-term use can easily lead to screw jamming, poor lubrication, etc., which increases the maintenance workload and repair costs of the screw lift. Utility Model Content

[0005] In response to the above-mentioned problems in the prior art, the present invention provides an intelligent logistics device for use in steel structure production, which solves the problem that existing mother-and-child vehicles are unable to transport and lift steel structure products.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] Provided is an intelligent logistics device for use in steel structure production, comprising a sub-trolley, which is moved by a first travel drive mechanism and arranged on a sub-trolley rail, and a scissor-type hydraulic lift for lifting the steel structure is provided on the top surface, and the scissor-type hydraulic lift is connected to the oil circuit of an external hydraulic system; a mother car, which is moved by a second travel drive mechanism and arranged on a mother car rail perpendicular to the sub-trolley rail, and a accommodating groove is provided on the top surface of the mother car for limiting the sub-trolley, and a secondary guide rail for moving the sub-trolley onto the sub-trolley rail is provided in the accommodating groove; the first travel drive mechanism, the second travel drive mechanism and the hydraulic system are all communicatively connected to an external control terminal.

[0008] In this solution, a three-dimensional coordinate system is established with the mother vehicle track as the X-axis and the sub-vehicle track as the Y-axis. The control terminal can control the mother vehicle to drive the sub-vehicle to move along the X-axis, and can control the sub-vehicle to detach from the mother vehicle and drive the steel structure to move along the Y-axis. After the sub-vehicle travels to the set distance, the steel structure is raised and lowered along the Z-axis by a scissor-type hydraulic lift, thereby realizing the transfer of steel structures between various workstations and achieving the function of automatic loading and unloading. By using a scissor-type hydraulic lift to replace the traditional screw jacking device, the lifting capacity and safety of heavy steel structure products can be effectively improved, which not only improves the handling efficiency, but also reduces labor costs and labor intensity. It is suitable for the handling of large and heavy steel structures. At the same time, through the communication connection of the control terminal, the sub-vehicle and the mother vehicle can be automatically transferred, realizing the intelligent logistics transportation of steel structures.

[0009] Furthermore, the scissor-type hydraulic lift includes a scissor linkage with a jacking seat at the top for supporting the steel structure. The scissor linkage is equipped with a hydraulic cylinder for driving the scissor linkage to retract or extend. The hydraulic cylinder is equipped with a hydraulic lock and is connected to the oil circuit of the hydraulic system. The hydraulic lock installed on the hydraulic cylinder can ensure that the hydraulic cylinder is safely locked in the event of sudden power outages, pipe bursts, and other emergencies during operation, thereby preventing pressure unloading in the event of a hydraulic system failure.

[0010] Furthermore, the sub-carriage track and the mother car track each include at least one pair of tracks, and each pair of tracks includes two guide rails.

[0011] Furthermore, the first travel drive mechanism includes two first drive wheels and two first travel wheels provided on the sub-carriage. The two first drive wheels are respectively fixed to opposite ends of a first transmission shaft. The first transmission shaft is chain-driven with a first reducer. The input end of the first reducer is fixedly connected to the input shaft of a first servo motor. The first servo motor is electrically connected to a first host computer. The first host computer is electrically connected to a first battery and a first communication module, respectively. The first communication module is communicatively connected to a control terminal. The sub-carriage is frequently used and requires regular maintenance. The first transmission shaft and the first reducer chain drive not only facilitate maintenance but also facilitate replacement, thereby reducing maintenance costs.

[0012] Furthermore, the second travel drive mechanism includes two second drive wheels and two second travel wheels provided on the mother vehicle. The two second drive wheels are respectively fixed to the ends of a second transmission shaft. The second transmission shaft is gear-driven with a second reducer. The input end of the second reducer is fixedly connected to the input shaft of a second servo motor. The second servo motor is electrically connected to a second host computer. The second host computer is electrically connected to a second battery and a second communication module, respectively. The second communication module is communicatively connected to a control terminal. Considering that the mother vehicle needs to move to the sub-vehicle track during operation and is responsible for carrying multiple sub-vehicles, which requires high transmission accuracy and stability, the second transmission shaft and the second reducer are gear-driven to ensure the high accuracy, high efficiency, and high reliability of the mother vehicle.

[0013] Furthermore, the first servo motor and the second servo motor are both provided with brakes. Adding brakes to the first servo motor and the second servo motor can quickly stop the motor operation in an emergency, avoid safety accidents caused by unexpected situations, and improve the safety performance of the system.

[0014] Furthermore, the first communication module and the second communication module are both WIFI modules. The WIFI modules facilitate remote communication between the sub-vehicle and the mother vehicle and the control terminal, enable more flexible data exchange, and enhance the intelligence level of the system.

[0015] Furthermore, the first host computer and the second host computer are both PLCs or single-chip microcomputers. The control units of PLCs or single-chip microcomputers have good stability and reliability and are suitable for precise control requirements in industrial environments.

[0016] Furthermore, the mother vehicle is equipped with safety radars at both ends of the vehicle body in the direction of travel. The safety radars can monitor the surrounding environment in real time and provide early warning of collision risks in the direction of travel, greatly improving the safety of the system and the work safety of operators.

[0017] Furthermore, the body of the mother vehicle is provided with anti-collision touch strips on both sides of the vehicle in the direction of travel. The anti-collision touch strips can prevent people from accidentally hitting the vehicle body from the side, ensuring the safety of equipment and personnel.

[0018] The utility model discloses an intelligent logistics device applied to steel structure production, which has the following beneficial effects:

[0019] 1. The utility model has the functions of intelligent scheduling, automatic handling, and pulling production, which can improve production efficiency and reduce costs. It replaces the traditional screw jacking device with a scissor-type hydraulic lift, which can effectively improve the jacking capacity and safety of heavy steel structure products, reduce equipment costs, and make maintenance simpler and more convenient, which is convenient for large-scale promotion. It not only improves handling efficiency, but also reduces labor costs and labor intensity. It is suitable for the handling operations of large and heavy steel structures.

[0020] 2. The utility model is remotely controlled by the control terminal, and automatically executes the sub-trolley, mother car and scissor-type hydraulic lift without manual intervention. Under the command of the control terminal, it intelligently connects to each workstation. When the production of the workstation is completed, the sub-trolley automatically performs the unloading work, and then automatically transfers the steel structure to the idle workstation of the next process according to the process route, realizing the intelligent transfer of the steel structure, ensuring that the steel structure is transferred to the next process as soon as the processing of each workstation is completed, avoiding waiting and waiting for materials, saving more than 20% of the equipment downtime waiting time, improving equipment utilization, and greatly improving production efficiency by driving production through materials.
