Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical manufacturing, and in particular to fluidized bed lifting devices. Background Technology
[0002] The internal fluidized bed of a railway cement tank car consists of a bottom support device and a permeable layer support device, each of which contains multiple components. Currently, the production process involves workers manually moving all the loose parts into the tank during the fluidized bed assembly step, and then sequentially assembling the two support devices inside the tank.
[0003] However, fluidized bed assembly is only one step in the entire tank truck production process. Due to limited workshop space, other subsequent processes cannot be carried out simultaneously while waiting for the fluidized bed to be assembled inside the tank, resulting in low overall production efficiency.
[0004] To improve production efficiency, the bottom support device and the permeable layer support device can be assembled separately on the outside of the tank. After both devices are pre-assembled, they can be moved to the half-tank of the cement tanker for installation. Summary of the Invention
[0005] The purpose of this invention is to provide a lifting device for fluidized bed operation inside railway cement tank cars. Using this device, the bottom support device and the permeable layer support device, pre-assembled on the outside of the tank, can be quickly and efficiently lifted into the half-tank of the cement tank car. Workers then efficiently assemble the two devices into a complete fluidized bed inside the tank. This significantly reduces the time the half-tank spends in the fluidized bed workshop, thereby improving the overall production efficiency of the cement tank car.
[0006] This utility model includes a lifting beam assembly and an auxiliary beam assembly.
[0007] The lifting beam assembly includes a lifting beam, uprights, lifting rings, hanging plates, wire rope A, wire rope B, and a counterweight. An upright is fixed to the upper part of the lifting beam, offset to one side from the center. The lifting beam is connected to the lifting rings via the uprights. Several hanging plates are located at the lower part of the lifting beam, with one end of wire rope A connected to one of the hanging plates. Wire rope B is connected to the lower part of the lifting beam near the uprights, and the free end of wire rope B is connected to the counterweight.
[0008] The auxiliary beam assembly includes a crossbeam, connecting plates, and crossbeam lugs. Several connecting plates are fixed to the lower part of the crossbeam, with both ends bent upwards and positioned at the corresponding ends of the crossbeam. Through holes are formed at the upward bends of the connecting plates, their positions corresponding to the through holes on the permeable layer support device. The auxiliary beam assembly is connected to the permeable layer support device. Crossbeam lugs are then fixed to the crossbeam.
[0009] Preferably, when lifting the bottom support device, the bottom support device is connected to the other end of the wire rope A.
[0010] Preferably, when lifting the air-permeable layer support device, the present invention also includes a lifting point connector, which is connected to the other end of the wire rope A and to the lifting lug of the crossbeam.
[0011] Preferably, the lifting point connector can be an arc-shaped shackle for the breathable layer support device.
[0012] Compared with existing technologies, this invention has the following advantages: Using this lifting device, the bottom support device and the permeable layer support device, pre-assembled on the outside of the tank, can be quickly and comprehensively lifted into the half-tank of the cement tanker. Workers can then efficiently assemble the two devices into a complete fluidized bed inside the tank. This significantly reduces the time the half-tank spends in the fluidized bed workshop, thereby improving the overall production efficiency of the cement tanker. Attached Figure Description
