Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] like Figure 1 to Figure 3 As shown, the plug door installation lifting device of the present invention comprises a main frame 1, a primary lifting frame 2, a secondary lifting frame 3, a door frame 4, an electric hoist 5, a handrail 6 and two steel ropes 7.
[0015] The bottom surface of the front end of the base 1-1 of the main frame 1 is equipped with a front moving wheel 1-1-1, the bottom surface of the rear end of the base 1-1 is equipped with a universal wheel 1-1-2, and the armrest 6 is fixedly connected to the support 1-6 the top of the rear end face. By holding and pushing the handrail 6, the lifting device can be driven to quickly move and adjust its position on the horizontal plane. Both sides of the front end of the bracket 1-6 of the main frame 1 are provided with slideways. No. 1 upper static pulley 1-2, No. 2 upper static pulley 1-3, ...

The sliding door installation lifting device belongs to the field of rail vehicle sliding door installation auxiliary lifting lifting device. The secondary passive lifting mechanism formed by the lifting frame, the secondary lifting frame and two steel ropes can stably and reliably lift the sliding door to the specified position precisely and provide an appropriate assembly inclination angle. During the operation process of using the device to lift and assemble the sliding door, the two operators standing on the ground do not need to lift the sliding door with both hands or hold the sliding door with their hands to maintain the balance of the sliding door. The operation process of the device is simple and labor-saving. Accurate positioning, safe and efficient, and can reduce the participation of at least one operator in the whole process, and reduce the labor occupancy rate, so the time and labor costs of the sliding door installation process can be greatly improved, and the production efficiency can be significantly improved. In addition, the device also has the advantages of low cost, easy popularization and the like.
Description
technical field [0001] The invention belongs to the field of an auxiliary lifting device for installing a sliding door of a rail vehicle, and in particular relates to a lifting device for installing a sliding door. Background technique [0002] At present, rail passenger cars usually arrange the vehicle frame on a 1.8-meter-high carriage stool. In this case, the height of the door frame on the vehicle frame from the ground is about 2 meters. When installing the sliding door on the door frame, the existing method usually adopts the manual lifting method. Two operators stand on the ground and lift the sliding door with their hands and gradually raise it until it exceeds the top of the head. Support the sliding door in the threshold of the car frame and fix it with bolts, and then the lower part of the sliding door is leaned against the rollers of the sliding path of the door frame by four people, and the installation process is completed. During the installation process, two ...
