Description

Technical Field

[0001] This invention relates to the technical field of oil injectors for autoclaved aerated concrete (AAC) trolleys, specifically to an oil injector for an AAC trolley. Background Technology

[0002] Autoclaved aerated concrete (AAC) block manufacturers consume a lot of energy, and accidents are prone to occur during operation. Uneven oil injection and inaccurate control of the oil volume are also issues. The amount of oil injected is crucial for equipment maintenance; too little oil fails to provide adequate lubrication, while too much oil generates high temperatures during high-speed operation, causing oil aging and hardening, leading to wear on bearing balls, increased motor load, and ultimately equipment damage. Furthermore, operational waste occurs during the process; failure to lubricate promptly and effectively results in bearing wear, disrupting the automated production line's speed and workflow, leading to idle machines, wasted energy, increased production costs, and wasted time. Therefore, an AAC curing trolley oil injector was designed to address these issues. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide an oil injector for an autoclaved concrete curing trolley.

The base plate has a slot penetrating through the base plate, the drive group traction mechanism is disposed within the slot, and the track is symmetrically arranged on both sides of the slot on the base plate. The steam curing trolley mechanism is disposed on the track and rolls with the track. The drive group traction mechanism and the steam curing trolley mechanism cooperate to pull the steam curing trolley mechanism. The oil injection device is symmetrically arranged on the base plate, and the locking trolley assembly is symmetrically arranged below the oil injection mechanism and on one side of the track on the base plate.

The upper end of the inverted T-shaped box 25 is connected to a crossbeam 22. The inverted T-shaped box 25 has notches 31 on both sides that communicate with it. Guide cylinders 27 are symmetrically arranged inside the inverted T-shaped box 25. A block 26 is located at one end of each guide cylinder 27 near the notch 31.

The clamp 35 has a clamping part 6 at its end.

[0029] In a specific implementation of this invention, when the steam curing trolley mechanism 4 passes through the autoclave and is pulled by the drive group traction mechanism 3, it approaches the oil injection device. The infrared sensor 12 on the first oil injection mechanism connecting beam 9 senses this and sends a signal to the PLC controller 10 on the first oil injection device. The PLC controller 10 then controls the oil injection device to start operating, locking the trolley assembly and hydraulic station unit 14 to begin working. When the moving steam curing trolley mechanism is sensed by the infrared sensor 12 on the second oil injection mechanism crossbeam 22, the locking trolley assembly tightens around the steam curing trolley mechanism 4 to fix it in place. The pneumatic cylinder 11 inside the housing 7 and housing 8 pushes the counterweight 24 to move, and the chain 23 drives the lifting pulley group 19 to work. When it reaches the designated position of the proximity switch 13, the pneumatic cylinder... 11 stops, and the air pressure tank unit 16 begins to maintain pressure; the pneumatic cylinder 11 becomes more stable, which stabilizes the lifting pulley block 19, and the oil injection mechanism starts to work. The guide cylinder 27 starts to work, pushing the block 26 to both sides and pushing the oil injection hose 30 into the oil injection hole of the trolley wheel. The PLC controller 10 sets the time of the electric control switch 17 and the pneumatic switch 18. First, air is sent from the air pressure tank unit 16 through the pipeline and the air check valve 29 into the oil injection hose 30 to blow air into the inside of the trolley's oil injection port, blowing away the impurities that were previously blocking the trolley's oil injection hole. After the end, the hydraulic station unit 14 starts to work after setting the parameters and controlling it, injecting oil into the trolley's oil injection hole through the oil check valve 28. After the end, the air check valve 29 works again to blow the oil that was just injected into the bearing with air to thoroughly lubricate it.

[0030] After the oil filling is completed, the pneumatic cylinder 11 begins to release air, causing the counterweight 24 that was just pushed up to slowly come down, thereby driving the lifting pulley group 19 to reset and avoid collision with the trolley. After the proximity switch 13 senses the lifting pulley group 19, the locking trolley assembly is released and clamped. When all is completed, the drive group traction mechanism 3 starts to run, pulling the steam curing trolley mechanism 4 to move out of the oil filling work area, and then taking the next steam curing trolley mechanism 4 to perform the oil filling work, and so on.

[0031] This enables intelligent control of the production line in this industry, allowing for flexible adjustments based on circumstances. It significantly reduces human error, eliminating situations where people forget to add or under-add oil, thus lowering production costs for manufacturers. The operating time of the steam curing trolley mechanism 4 is greatly extended, preventing breakage and collapse of the upper aerated concrete block due to bearing wear. This reduces waste and turnaround time in the production process, greatly improving machine control, ensuring stable quality, and eliminating pollution. Simultaneously, it reduces labor costs and the risk of accidents due to improper operation, lowering the overall energy consumption of the production line.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
