The invention provides a gearbox disassembly and assembly bracket device. The gearbox disassembly and assembly bracket device comprises a base, a hydraulic cylinder and a tray used for bearing a gearbox. A cylinder body of the hydraulic cylinder is connected with the base, and a telescopic rod of the hydraulic cylinder is connected with the tray to drive the tray to lift; the gearbox disassembly and assembly bracket device further comprises a manual pump unit used for driving the telescopic rod of the hydraulic cylinder to stretch out and draw back and an electric pump unit used for driving the telescopic rod of the hydraulic cylinder to stretch out and draw back. According to the gearbox disassembly and assembly bracket device, under the normal condition, the electric pump unit is adopted for driving and controlling the telescopic motion of the telescopic rod of the hydraulic cylinder so as to achieve lifting and descending of the tray, and compared with the structure that the hydraulic cylinder is controlled by pressing a pressing rod in the prior art, the gearbox disassembly and assembly bracket device is more convenient to use. And meanwhile, when the electric pump unit breaks down or loses power supply, the manual pump unit can be adopted to independently drive and control the hydraulic cylinder to work normally, the reliability of the hydraulic system can be effectively improved, and the service life can be prolonged.
本申请提供一种变速箱拆装托架装置,包括:底座、液压缸和用于承托变速箱的托盘;液压缸的缸体与底座连接,液压缸的伸缩杆与托盘连接,以带动托盘升降;变速箱拆装托架装置还包括用于驱动液压缸的伸缩杆伸缩的手动泵单元和用于驱动液压缸的伸缩杆伸缩的电动泵单元。本申请提供的变速箱拆装托架装置在正常情况下,采用电动泵单元驱动控制液压缸的伸缩杆的伸缩动作,以实现托盘的举升和下降,相比于现有技术中通过按压压杆控制液压缸的结构,本申请使用更加便利。同时,在电动泵单元出现故障或失去供电时,还能够采用手动泵单元独立的驱动控制液压缸正常工作,能够有效的提高本申请的可靠性,也有助于延长使用寿命。
