Problems solved by technology

[0004] The inventors found that the current traditional rail power tractor has a very large weight and external dimensions, which limits the scope of use of the rail tractor. This is because the traditional rail tractor needs to use its own weight to increase the driving wheel and the rail support top surface The friction force between them, so that the output provides a greater traction force; because the support surface of the rail top supports the train for a long time, the surface is relatively smooth, so in order to increase the overall traction force, the weight of the tractor needs to be increased to increase the traction output force The purpose; resulting in a narrow range of rail tractors, larger volume, weight tractors can hardly meet the needs of the current track inspection and maintenance, cargo transportation process

Embodiment 1

[0034] In a typical implementation of the present disclosure, such as Figure 1-Figure 6 As shown, a lightweight rail traction device based on the spring pressing force is proposed.

[0035] The traction device 1 is placed on the track 2 and the overall appearance is as follows: figure 1 shown;

[0036] The top view of the traction device is as follows figure 2 As shown, the main structure is a fixed plate 5 and a vehicle frame 6, the fixed plate is installed on the vehicle frame, and other structures mainly include a power wheel set 3, a supporting wheel set 8, a pull rod mechanism 11, and a traction mechanism 10;

[0037] For the power wheel set, it is used as the driving element of the whole traction device, including a sliding bracket, a motor slider 18, a driving motor 13 and a power wheel 20, the motor slider is slidably installed on the sliding bracket through a linear bearing 12, and the driving motor is installed on the motor. The slider is connected to the power ...

Embodiment 2

[0065] In another typical implementation of the present disclosure, such as Figure 1-Figure 6 As shown, a rail transportation device is proposed.

[0066] The rail transportation equipment includes the traction device and the transport tractor as described in Embodiment 1. The traction device is connected to the transport tractor through the traction mechanism at the end, and drives the transport tractor to move along the track.

[0067] It solves the problem that the traditional rail tractor needs to use its own weight to increase the friction between the driving wheel and the rail support top surface, and the light-weight rail traction device can also output and provide greater traction.

Abstract

The disclosure provides a light-weight rail traction device and transportation equipment based on spring compression force, which relates to the field of rail tractors, including a fixed plate, a support wheel set, a power wheel set, and a pull rod mechanism installed on the fixed plate, and the support wheel set It includes at least three supporting wheels that are rotatably connected to the fixed plate, and are used to support the fixed plate with two rails. Power wheels are slidably installed on both sides of the fixed plate, and the power wheels are located between the two rails. The power wheels The power wheel can be attached to the side of the track or detached from the side of the track under the action of the pull rod mechanism, and the supporting wheel set and the driving wheel set that are separated from each other are set. The supporting wheel set contacts the top surface of the track to provide support for the traction device as a whole. The driving wheel set It abuts against the side of the rail with a large friction coefficient, thereby driving the traction device to move along the rail as a whole, without additionally increasing the weight of the traction device, so as to achieve the effect of increasing the driving force of the traction device.

Description

technical field [0001] The disclosure relates to the field of rail tractors, in particular to a lightweight rail traction device and transportation equipment based on spring pressing force. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Rail tractors can be used in track inspection and maintenance, cargo transportation, etc., to provide power for inspection vehicles, trolleys, transport vehicles, etc. that do not have a power drive system. [0004] The inventors found that the current traditional rail power tractor has a very large weight and external dimensions, which limits the scope of use of the rail tractor. This is because the traditional rail tractor needs to use its own weight to increase the driving wheel and the rail support top surface The friction force between them, so that the output provides a greater traction force; bec...
