Description

Gate fixed wheel bearing dismounting device Technical Field The utility model relates to the field of gate fixed wheel disassembly and assembly, in particular to a gate fixed wheel bearing disassembly device. Background The fixed wheel gate is a plane gate with fixed wheels arranged on the gate edge beam as a supporting walking component, has larger bearing water head and is widely applied to working gates, accident gates, overhaul gates and the like in hydroelectric engineering. The plane fixed wheel gate moves up and down in the gate slot, and wheels in the fixed wheel device rotate during operation to generate reaction force with cast steel tracks in the gate slot, and the side water seal and the top water seal on the panel are extruded, so that the compression amount of the gate side water seal and the top water seal rubber is ensured, and water leakage of the gate can not occur during closing. The fixed wheel equipment generally comprises a wheel frame, a wheel shaft, a self-aligning roller bearing, a wheel and other parts. In order to solve the problems in the prior art, the utility model with the bulletin number of CN218952U discloses a protection device for the plane fixed wheel gate fixed wheel equipment, which comprises a screen, two sides of the screen are connected with brackets, the brackets or the screen are detachably provided with soft baffles, the screen is used for shielding the top end of the fixed wheel equipment, and the soft baffles are used for contacting with a fixed wheel working surface. In the prior art 1, when the fixed wheel equipment works, sundries in water cannot enter the fixed wheel equipment to ensure that wheels in the fixed wheel equipment normally rotate, but because the fixed wheel of the gate is soaked under water for a long time and needs to frequently act under water pressure, even if the sundries in water are isolated by the isolating net and the baffle in the prior art 1, the bearing of the fixed wheel of the gate still can be worn and blocked, and in the prior art, the fixed wheel bearing is broken and detached in a carbon arc gouging mode, so that the fixed wheel bearing and a bearing seat are easily damaged. Disclosure of utility model The utility model aims to provide a gate fixed wheel bearing dismounting device which can solve the problem that the fixed wheel bearing and a bearing seat are easy to damage due to the fact that the fixed wheel bearing is broken and dismounted by adopting a carbon arc gouging manner in the prior art in the actual use process.
