The invention discloses a maintenance car convenient for climbing an escalator, and belongs to the technical field of equipment maintenance. The device comprises a base, a storage box, a safety mechanism, a pull handle piece, a walking mechanism and a cover plate piece. A storage box is installed on the surface of the base, a safety mechanism is arranged on the inner side of the storage box and comprises a pair of first electric push rod devices which are installed on the inner side of the storage box and face opposite directions, and column bodies which penetrate through and extend to the outer side of the storage box are installed at the output ends of the first electric push rod devices. When the U-shaped pull handle is held, the button switch is pressed, so that the push rod of the first electric push rod device is in a retraction state when the button switch is pressed, and when the maintenance car needs to be parked on the escalator, the hand is loosened from the button switch, and the button switch loses pressing. A push rod of the first electric push rod device rapidly pushes a column body to stretch out, the column body is clamped on a fence on the side edge of the escalator in a self-adaption mode, safety accidents caused by sliding and inclining of the maintenance car are avoided, and the safety of the maintenance car on the escalator is improved.
本发明公开一种便于攀爬扶梯的检修车,属于设备维修技术领域。其包括底座、存放箱、保险机构、拉柄件、行走机构与盖板件;所述底座的表面安装有存放箱,所述存放箱的内侧设有保险机构,所述保险机构包括安装于存放箱内侧的一对朝向相反的电动推杆器一,所述电动推杆器一的输出端安装有贯穿并延伸至存放箱外侧的柱体;握持U型拉柄时,压动按钮开关,使得电动推杆器一的推杆在按钮开关被按压时处于回缩状态,当需要在扶梯上进行停放检修车时,手部与按钮开关松开,按钮开关失去压动,电动推杆器一的推杆快速推动柱体伸出并且柱体自适应卡在扶梯侧边的围栏上,避免了检修车因为滑动和倾斜的原因造成安全事故发生,提高了检修车在扶梯上的安全性。
