Problems solved by technology
[0003] In order to solve the problem that when a tractor is used as the traction power device of an unpowered train, the fifth wheel of the tractor is usually fixed in height and needs to be selected and replaced according to the type of train being towed. The process of replacing the coupler is time-consuming and laborious, and the technical problem is low efficiency. The invention provides a train variable position traction tool

Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0019] Such as Figure 1 to Figure 10 As shown, the train variable displacement traction tooling of the present invention includes a track frame 1, a jack 2, two chains 3, a lifting base 4, a displacement coupler seat 5, a swivel seat 6, four rollers 7, a first latch 8, The second latch 9 , two buffer spring pins 10 , the high position limiting block 11 and the low position limiting plate 12 . Track frame 1 is placed vertically, and its two sides are provided with vertically parallel channel steel tracks, and the middle part of the front end face of track frame 1 rear panel is provided with horizontal plate.
[0020] The jack 2 comprises a compression rod 2-1, an oil cylinder 2-2, a piston rod 2-3 and a T-shaped transverse shaft 2-4, and the oil cylinder 2-2 is fixedly connected with the bottom plate of the track frame 1 through its own oil cylinder seat, an...

The train variable-position traction tooling of the present invention belongs to the field of auxiliary traction devices for rail vehicles when they are newly built and overhauled. The movable pulley lifting mechanism formed by the piston rod chain of the jack can drive the lifting base and make the lifting base move along the channel steel guide rail of the track frame. Vertical lifting movement, so as to realize height displacement switching. Four positioning guide rollers can slide in the channel steel track. The swivel seat that can be displaced at right angles along the vertical axis realizes the rotation switching between the close-fit coupler connection seat and the shaft-connected coupler seat. The rubber bushing with a convex spherical surface in the swivel seat and the concave spherical shaft cavity together form a ball-and-socket cavity The spherical kinematic pair can withstand a certain radial overturning moment, so that the swivel seat has degrees of freedom in two directions, thereby buffering and protecting the coupler from severe bumps and impact damage. The buffer spring pins respectively act on the lower end surfaces of the closely-connected coupler connecting seat and the shaft-connected coupler seat to support, buffer and limit and protect the rotating seat.
Description
technical field [0001] The invention belongs to the field of auxiliary traction devices for rail vehicle new build and maintenance, and in particular relates to a train variable displacement traction tool. Background technique [0002] The tractor is occasionally used as the traction power device of the unpowered train during the new construction and maintenance of rail vehicles, but the couplers of the train usually include two types of shaft-connected couplers and end-face-closed couplers. Dummy trolleys are used when driving, and the horizontal height of the couplers is also very different, while the fifth wheel of the tractor is usually fixed in height and can only match one of the shaft-connected coupler or the end-face close-fitting coupler. If the coupler of the tractor is matched and replaced in advance before the tractor is connected to and pulls the train, it will consume manpower and material resources, affect production efficiency, and is extremely inconvenient. ...
