Description

Technical field: The invention relates to a bamboo carbonization kiln door linkage locking device and a working method thereof. Background technology: The linkage locking device for bamboo carbonization kiln door is an innovative technological breakthrough aimed at solving the problems of low efficiency, high labor intensity and many safety hazards in the current production process of bamboo carbonization kiln. The linkage locking device deeply integrates the length of gear rack and automatic control technology, aiming to comprehensively improve the automation level of bamboo loading and unloading in bamboo carbonization kiln, thereby significantly improving production efficiency, reducing production costs and optimizing the working environment of workers. One of the core components of the device, gear rack linkage locking, is designed to use "low backlash" or "zero backlash" as much as possible. The linkage locking device has a long service life, stable operation, high reliability and can ensure a constant transmission ratio. The linkage locking device improves the airtightness of the kiln door, transmits large power, can firmly clamp the linkage lock fixing block and fasteners of the locking mechanism, and also ensures the locking stability of the kiln door. Even in long-term continuous operation or facing complex working conditions, the linkage lock fixing block and fasteners can be kept stable and not loose, effectively avoiding the risk of slipping or displacement that may occur in traditional mechanical clamping methods, greatly enhancing the safety of the operation. The electric system is the key system for driving the lifting and translation of the rack of the linkage locking device. The electric system is strictly calculated by mechanical calculation and verified in actual application scenarios to ensure stable operation under high load and high frequency operation. At the same time, the kiln door control system specially integrates the temperature and pressure sensing in the kiln. Through precise temperature control and pressure regulation, the motor movement speed is precisely controlled, which not only ensures the rapid response and safe opening and closing of the operation, but also ensures the smooth and impact-free movement, further improving the overall performance and service life of the equipment.

[0003] The locking technology in the prior art often relies on the strategy of fixing multiple holes separately. This method often has certain shortcomings in the actual locking operation process. Specifically, since each door latch needs to be fixed separately, it is easy for the staff to make mistakes when performing the locking work, resulting in a door latch not being fixed, which ultimately leads to the door not being locked. In the actual operation process, the installer needs to fasten each lock one by one, which increases the time cost of the work. This inefficient working method will cause delays in the entire workflow and affect the production schedule.

[0004] At present, a Chinese patent "Interlocking device for the door of the incoming cabinet and the fixed metering cabinet" has been retrieved, with announcement number CN216624942U, which includes a connecting rod, a first roller is provided at one end of the connecting rod, a second roller is provided at the other end of the connecting rod, a first connecting plate is provided at the end of the connecting rod close to the first roller, the first connecting plate and the second connecting plate are both connected to the inner wall of the metering cabinet, a rotating arm is sleeved on the second roller, and the end of the rotating arm away from the second roller is connected to the incoming cabinet, an adjustment hole is provided on the rotating arm, and an elastic member is provided between the rotating arm and the second connecting plate. The interlocking device realizes the linkage locking function of the incoming cabinet and the metering cabinet. When the circuit breaker in the incoming cabinet is in the working position, the interlocking device realizes the mechanical locking of the front and rear doors of the metering cabinet to prevent misoperation caused by electrical interlocking failure, which causes harm to the operator and a series of illegal operations such as opening the metering cabinet door to steal electricity when the incoming cabinet is energized; but the device cannot perform multi-directional latching and locking of the door body.

[0005] In addition, a Chinese patent "A rotary cam-linked sealed door locking device" was retrieved, publication number CN109519100A, which includes: a locking outer frame assembly and a pressing inner frame assembly, which uses a linkage pull rod to drive multiple cams on three sides of the sealed door to rotate synchronously, so that the spiral surface of the end face locking cam corresponds to the pressing protrusion on the door edge pressing inner frame one by one, and the extrusion is pushed to form a bite, so that the sealing door edge and the locking outer frame are evenly extruded and contacted, meeting the sealing and locking requirements of laboratory doors with high environmental sealing requirements, ensuring reliable sealing and accurate experiments; but the device cannot perform multi-directional latching and locking of the door body. Summary of the invention: In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a bamboo carbonizing kiln door linkage locking device and a working method thereof.
