Embodiment Construction

[0009] Referring to accompanying drawing 1, its structure is that rotating motor 1 is connected with drive screw shaft 4 through key, and rotating motor 1 is connected with hoisting frame 7 by bolt and is fixed on the hoisting frame 7, and driving screw shaft 4 is rotated through the left sleeve. 2. The right rotation sleeve 6 is connected with the lifting frame 7. The transmission screw shaft 4 is threaded with the left claw 3 and the right claw 5. Because the transmission screw shaft 4 is connected with the rotary motor 1, and the left claw 3 and the right claw 5 are threadedly connected with the transmission screw shaft 4, the transmission screw shaft 4 is driven by the rotary motor 1 to rotate. Reversing can make the left claw 3 and the right claw 5 threadedly connected with the transmission screw shaft 4, so that the left and right claws 3 and 5 can be relatively closed or opened.

[0010] The left claw 5 and the right claw 6 are in the shape of hooks, which can fix the b...

Abstract

The invention relates to a lifting device of sway bogie using in the production and maintenance process of railway vehicles when the sway bogie transports. It is characterized by: rotating motor is linked with the drive leading screw axis by keys and fixed on the suspending frame through bolts, the drive leading screw axis is matched and linked with the suspending frame through the left and right rotate packages, and it also is linked with the left and right jackcatch screwthread. Its advantages are: making the manufacture and maintenance of sway bogie more efficient, meeting the needs of technique skillfully, achieving the pipelining repair and manufacture, solving the problem of lifting of the sway bogie, it is a reliable lifting device of sway bogie with multi-adaptability and lays the groundwork for faster transportation of bogie. Its application is wide, it makes claws closed or open using of the drive of screw and adapts to different bogie and different width swing bolster in the mixed multi-line transportation or the multi- products transportation; the structure is simple and convenient, the screw drive ensures the positioning accurate and claws clamps exact and lifting smooth and efficient.

Description

technical field [0001] The invention relates to a bogie hoisting device used for the bogie aerial transportation of the bogie for the convenience of the bogie aerial transportation during the production and maintenance of the railway car body, and belongs to the technical field of transportation equipment. Background technique [0002] Most of the existing train frame maintenance adopts the platform-type maintenance method, which is a simple ground-type fixing method. Its disadvantages are: inconvenient maintenance and difficult movement and flipping. It is to extend the fixed rotating block into the padlock hole, fix and lock it after rotating, and hang the bogie. Such structural mode just can't be applicable to the padlock hole of model changeable, and applicable surface is too narrow, and use is severely limited. Contents of the invention [0003] The purpose of the present invention is to propose a way to fix the bogie, use the screw to drive the movable claws, shorte...
