Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0027] The invention uses a lifting device to realize semi-mechanized installation. Five lifting devices are placed on the wiring site at intervals to form a wiring workbench. The trunking box is placed on the upper platform of the lifting device for the operator to perform wiring operations. Five other lifting devices are also placed at intervals in the car to form a workbench for installation in the car. The rolling ball mechanism of the lifting device can make the trunking box move back and forth freely and conveniently on the upper platform. The trunking box can be clamped or loosened by the eccentric locking shaft of the lifting device, and the trunking box can be raised or lowered to the required position by the lifting function of the lower liftable trolley. The universal wheels with self-locking function on the bottom liftable trolley...

Abstract

The invention relates to the technical field of mounting of top trunking boxes in railway vehicles, in particular to a lifting device for mounting a top trunking box in a passenger train and a mounting method of the trunking box. The lifting device comprises an upper platform, a ball mechanism, a lower liftable cart and multiple eccentric locking shafts; the lower end surface of the upper platformis fixedly connected with the top of the lower liftable cart; the ball mechanism is located on the upper end surface of the upper platform and is rotationally connected with the upper platform; multiple inserting holes are formed in the upper end surface of the upper platform at equal intervals; the eccentric locking shafts are screwed into the inserting holes in a one-to-one correspondence manner; and universal wheels with the self-locking function are arranged at the bottom of the lower liftable cart. The lifting device can be rapidly and conveniently lifted, transported and installed, theproduction efficiency and the installation quality can be improved, and the personal safety can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of installation of a wire groove box at the top of a rail vehicle, in particular to a lifting device for installing a wire groove box at the top of a railway passenger car and an installation method thereof. Background technique [0002] In the assembly operation of the trunking box on the top of the railway passenger car in the past, manual lifting, manual transportation, manual boarding, manual lifting and installation, etc. are used, which are labor-intensive and extremely backward in operation. The trunking box is more than 20 meters long, 200mm wide, 50mm thick, and 600kg in weight. It is long in size and poor in rigidity. There has been no special equipment to transport it to the car for installation. It takes 8 workers to carry it from the wiring site, and manually transport it to the door of the car body at the assembly site of more than 100 meters, and then 8 workers under the car cooperate with 8 w...
