Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stacker failure monitoring, and more specifically, to an intelligent monitoring device for hydraulic brake system failure. Background Art
[0002] The SBS hydraulic brake system (SBS) is a core component of the stacker crane, responsible for immediately applying emergency braking in the event of a safety malfunction, safeguarding the crane, finished products, and auxiliary materials. However, SBS brake failures frequently occur during normal operation. This is a persistent and common problem that directly and severely impacts the normal operation of the stacker crane and reduces the efficiency of elevated finished product maintenance. Due to the complex structure of the SBS hydraulic brake system and the multiple causes of failure, many failures remain difficult to pinpoint, creating an urgent need for resolution.
[0003] The SBS hydraulic brake system primarily consists of the SMS2000, which in turn comprises four geomagnetic sensors (s561, s562, s563, and s564), an encoder (P565), two solenoid valves (Y567 and Y568), and a pressure sensor (S569). The mechanical portion primarily comprises a brake mechanism, an oil pump motor, and a gear pump. Failure in any of these components will cause the SBS hydraulic brake system to initiate an emergency braking operation. Furthermore, a leak in the mechanical oil circuit, causing the oil pressure to fall below the warning level, can also cause the SBS to engage. For example, the SBS hydraulic brake system on the Vecturas 22 stacker crane utilizes a mechanical booster. When an SBS failure occurs, the SBS hydraulic brake system initiates an emergency braking operation, which the system displays as an SBS failure. The specific cause of the failure requires further investigation. When an SBS fault alarm occurs, it can be divided into a brake system fault and an electrical system fault: When the brake system fails, it is mainly necessary to check whether the oil pump motor is normal, whether there is oil leakage in the oil circuit, and whether there is oil leakage in the brake piston, and conduct an item-by-item inspection. If there is a related oil circuit leakage, replace the relevant parts; when the electrical system fails, it is necessary to determine whether the pressure sensor, solenoid valve and SMS front section are faulty, and check them one by one, and replace the faulty electrical components after inspection.
[0004] The above troubleshooting solution for the SBS hydraulic brake system has the following defects:
[0005] 1. All relevant components are integrated internally and cannot be directly observed from the outside. The oil pressure value, which is a key factor, is mechanically set and cannot be displayed or adjusted. As a result, repair personnel are unable to determine the fault location based on the relevant information.
[0006] 2. In the traditional maintenance method, the cause of the fault is checked one by one, which takes a lot of time and affects the operating efficiency of the stacker. In the process of troubleshooting, other parts may be damaged. Utility Model Content

[0013] Optionally, the basic component further includes a brake friction pad, which is connected to the hydraulic brake mechanism.

[0032] The utility model proposes an embodiment of an intelligent monitoring device for hydraulic brake system failure. Specifically, Figures 1 to 4 shown, including:
[0033] Basic components and monitoring components, wherein the basic components include a hydraulic oil pump motor 4, a hydraulic oil pump 5, hydraulic oil pipes 6, 7, a hydraulic oil tank 8, a hydraulic brake mechanism 9 and a hydraulic control valve 11. The hydraulic oil pump motor 4 is connected to the hydraulic oil pump 5 in a transmission manner. The hydraulic oil pump 5 pressurizes the hydraulic oil in the hydraulic oil tank 8 and delivers it to the hydraulic brake mechanism 9 and the hydraulic control valve 11. The monitoring components include electromagnetic control valves 12, 13, a digital oil pressure control meter 14 and a pressure detector 15. The digital oil pressure control meter 14 is connected to the original hydraulic brake system through an oil distributor. Among them, the electromagnetic control valves include electromagnetic control valves Y567 and electromagnetic control valves Y568. The pressure detector 15 is as shown in FIG. Figure 4 The pressure detector S569 shown in .
[0034] It should be noted that the hydraulic oil pump 5 is connected to the hydraulic brake mechanism 9 and the hydraulic control valve 11 via hydraulic oil pipes 6 and 7. The digital oil pressure control meter 14 is connected to the hydraulic oil pipes 6 and 7 and the hydraulic control valve 11 in the hydraulic brake system. The oil pressure value is obtained and displayed via a pressure detector. The pressure detector 15 converts the detected oil pressure signal into an electrical signal and transmits it to the digital oil pressure control meter 14. The digital oil pressure control meter 14 determines whether the brake system is in normal working condition by comparing it with the preset oil pressure range and outputs an alarm indication in the event of an abnormality. The digital oil pressure control meter and pressure detector can monitor the oil pressure changes in the hydraulic brake system in real time, and can promptly detect and address faults and abnormalities in the hydraulic brake system, thereby avoiding accidents and improving the safety of the system.
[0035] In the embodiment of the present utility model, the electromagnetic control valves 12 , 13 , the digital oil pressure control meter 14 and the pressure detector 15 are all connected to the hydraulic control valve 11 .
[0036] In this embodiment of the utility model, the pressure input of the digital oil pressure control gauge 14 is equipped with a quick-release mount. The mount is made of a durable material such as metal or plastic. Specifically, the mount is a waterproof, four-hole standard quick-release mount. The mount has four connection holes, allowing for simultaneous connection to four oil circuits or detection lines, enhancing the system's flexibility and scalability. The waterproof feature effectively prevents moisture damage to the digital oil pressure control gauge, extending its service life.
[0037] In an embodiment of the present invention, a quick-release jumper is provided at the electromagnetic control valves 12 and 13. The quick-release jumper is used to extract 220V AC power from the electrical circuits of the electromagnetic control valves 12 and 13. The other end of the quick-release jumper is connected to the power input of the digital oil pressure control meter 14, thereby providing power to the digital oil pressure control meter. The quick-release jumper consists of a plug and a socket. The plug has conductive pins, and the socket has corresponding jacks. The electrical circuit can be quickly connected and disconnected through a simple plug-in and unplug operation. The quick-release jumper is typically designed to be waterproof and dustproof, helping to prevent electrical circuit failures caused by problems such as poor contact or short circuits.
[0038] In an embodiment of the present invention, the basic components also include brake friction pads 16, 17, which are connected to the hydraulic brake mechanism 9. After the hydraulic oil flows into the hydraulic brake mechanism 9, it pushes the brake friction pads 16, 17 to contact the brake disc or brake drum, generating a friction torque.
[0039] In this embodiment of the utility model, a digital oil pressure control gauge 14 monitors and displays the oil pressure of the hydraulic brake mechanism 9 in real time. When the oil pressure is outside a preset range, the hydraulic oil pump 5 automatically increases pressure. When the oil pressure is within the preset range, the signal light on the pressure detector 15 illuminates, indicating that the brake system is operating normally. The hydraulic oil pump then stops operating, saving energy and extending equipment life. Specifically, the lower oil pressure warning threshold is set at 120 bar. When the oil pressure falls below 120 bar, the oil pump automatically increases pressure, reducing the risk of the SBS hydraulic brake system locking due to oil pressure falling below the warning threshold. The digital oil pressure control gauge monitors and displays the oil pressure of the hydraulic brake mechanism in real time, allowing the operator to intuitively understand the pressure status of the brake system and take necessary measures to ensure the safety and reliability of the brake system. When the oil pressure is outside the preset range, the hydraulic oil pump automatically increases pressure to ensure the normal operation of the brake system. By monitoring the oil pressure in real time and automatically adjusting the oil pressure, the brake system maintains stable performance under various operating conditions, thereby improving vehicle safety.
[0040] It should be noted that through the visualization and controllability of the oil pressure, the specific location of the SBS hydraulic brake system fault can be determined based on the oil pressure value of the digital oil pressure control meter 14 and the corresponding signal. The specific fault identification method is as follows:
[0041] (1) When the oil pressure value cannot reach the set value, first check the mechanical structure to see if there is any oil leakage;
[0042] (2) When the oil circuit is normal and the oil pressure value cannot reach the set value, it can be determined that the solenoid valve has internal leakage;
[0043] (3) When the oil pressure value is normal and the pressure detector signal light is on, it means that the pressure detector is faulty and needs to be replaced accordingly;
[0044] (4) If the oil pressure value is not displayed at all or the oil pressure and pressure detector are normal after restart, it means that the SMS2000 front section is faulty.
[0045] Specifically, if Figure 4 The figure shows the control circuit diagram of the intelligent monitoring device. The electric contact pressure controller controls the circuit's on / off state by opening and closing electrical contacts based on pressure changes within the system. "NO" represents a normally open contact, and "NC" represents a normally closed contact. These contacts work in conjunction with multiple relays and circuit breakers to implement brake control for the SBS hydraulic brake system.
[0046] In this embodiment of the utility model, the basic assembly also includes a steel track 1, a stacker wheel frame 2, and stacker running wheels 3. The stacker wheel frame 2 is used to support the stacker running wheels 3, allowing the stacker to move on the steel track 1. When the stacker needs to move, the hydraulic oil pump motor 4 drives the stacker running wheels 3 to rotate, causing the stacker to move along the steel track 1. The stacker wheel frame 2 supports the stacker running wheels 3 and transfers the load, ensuring that the stacker remains stable during movement.
[0047] In the embodiment of the present invention, the basic assembly further includes a guide wheel 10, which is fixedly connected to the stacker body and installed on one side of the steel track 1 to ensure that the stacker runs stably along the steel track 1 during movement.
[0048] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
