Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a monitoring device for a gyratory crusher. Background Technology

[0002] During operation, the flow rate, pressure, and temperature of the lubrication system, as well as the mechanical condition of gears and bearings, directly affect the performance and lifespan of the gyratory crusher. Traditional monitoring methods have the following drawbacks: oil circuit parameters (flow rate, pressure, and temperature) and equipment mechanical condition (gear and bearing vibration) need to be monitored separately by independent devices, resulting in fragmented data that is difficult to monitor and analyze synchronously. Furthermore, lubrication stations are usually located far from the crusher main unit, requiring maintenance personnel to travel to multiple locations to check data, which is inefficient.

However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0019] like Figures 1-4As shown, this embodiment provides a monitoring device for a gyratory crusher, including a housing 1. A pressure sensor display 2, a temperature sensor display 3, and a vibration sensor 4 are fixedly installed inside the housing 1. A terminal box 5 is fixedly installed on the outer wall of the housing 1. A hydraulic valve assembly 6 is installed inside the housing 1. A flow meter 7 connected to the hydraulic valve assembly 6 via pipes and bolts is also installed inside the housing 1. The temperature sensor display 3 and the vibration sensor 4 are provided with a first waterproof connector 8 extending out of the housing 1. The hydraulic valve assembly 6 includes a valve body 601 located inside the housing 1. A pressure sensor probe 602 and a temperature sensor probe 603 are fixedly installed on the valve body 601. The temperature sensor display 3 is electrically connected to the temperature sensor probe 603. The probe 602 is electrically connected to the pressure sensor display 2. The pressure signal of the lubricating oil circuit is transmitted to the pressure sensor display 2 through the pressure sensor probe 602, and the temperature signal is transmitted to the temperature sensor display 3 through the temperature sensor probe 603. The pressure and temperature data of the oil circuit can be collected in real time. The gear and bearing monitoring signals of the gyratory crusher host are input to the vibration sensor 4 through the first waterproof connector 8. The vibration sensor 4 receives the vibration signals of the gear and bearing of the crusher host through the first waterproof connector 8, realizing the synchronous monitoring of the mechanical status of the equipment and the oil circuit parameters. The oil circuit flow, pressure, and temperature monitoring and gear or bearing vibration monitoring are integrated into a single device, realizing centralized display and analysis of data, avoiding the need for maintenance personnel to travel to multiple points to check the data, and improving monitoring efficiency.

[0020] The hydraulic valve assembly 6 is fixed inside the housing 1 by bolts, which allows for the fixed installation of the hydraulic valve assembly 6.

[0021] The pressure sensor display 2, temperature sensor display 3, vibration sensor 4, and terminal box 5 are all fixed to the housing 1 with screws, which facilitates disassembly, maintenance, or replacement of components and improves maintainability.

[0022] The pressure sensor probe 602 and the temperature sensor probe 603 are both threaded onto the valve body 601, ensuring sealing and facilitating calibration or replacement of the pressure sensor probe 602 and the temperature sensor probe 603.

[0023] The cables of the flow meter 7, pressure sensor display 2, temperature sensor display 3 and vibration sensor 4 are all electrically connected to the terminal box 5 via the second waterproof connector 9 to prevent oil and water vapor from entering the circuit and improve reliability.

[0024] The bottom of the enclosure 1 is provided with a support frame 10, which can prevent the enclosure 1 from being supported and avoid the enclosure 1 from being in direct contact with the ground, which may cause the equipment to be corroded by water accumulation on the ground. At the same time, it is conducive to the laying of cables at the bottom.

[0025] The front of the enclosure 1 has an opening, and the opening of the enclosure 1 is connected to a door 11 by a hinge, which facilitates quick opening and closing, makes it convenient to inspect the internal components of the enclosure 1, and protects the equipment from external dust.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] During operation, the pressure signal of the lubricating oil circuit is transmitted to the pressure sensor display 2 via the pressure sensor probe 602, and the temperature signal is transmitted to the temperature sensor display 3 via the temperature sensor probe 603. This allows for real-time acquisition of oil circuit pressure and temperature data. The gear and bearing monitoring signals of the gyratory crusher host are input to the vibration sensor 4 via the first waterproof connector 8. The vibration sensor 4 receives the vibration signals of the crusher host gear and bearing via the first waterproof connector 8, achieving synchronous monitoring of the equipment's mechanical status and oil circuit parameters. This integrates oil circuit flow, pressure, and temperature monitoring with gear or bearing vibration monitoring into a single device, enabling centralized display and analysis of data. This avoids maintenance personnel having to travel to multiple locations to check data, thus improving monitoring efficiency.

[0028] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
