technical field

The invention relates to the field of railcars, in particular to a single-track and double-track dual-purpose track based on chain drive with self-positioning function, which can be driven on single-track and double-track by switching between two tracks, which can meet the operating conditions of different grounds and has self-positioning function. car body.

Background technique

Rail Guide Vehicle (RGV for short), also known as shuttle vehicle, has the characteristics of fast speed, high reliability, and low cost. It is widely used in logistics systems, and aluminum alloy or steel is usually used as the rail material. Present shuttle car is mainly made up of mechanism such as vehicle frame, front and rear drive wheel, follower wheel. The track-type automatic guided vehicle used in logistics, the track only plays a guiding role, and the car body needs to be supported by follower wheels in contact with the ground to solve the problem of track load. This track-type automatic guided vehicle has a small track size, but at the same time it bears light weight. It needs to be supported by the follower wheel and the ground. The track only plays a guiding role. The follower wheel is in contact with the ground. It is only used in indoor environment, and the scope of application is very limited.

Monorail track-type automatic guided vehicles are also widely used in railways, urban rail transit, and entertainment occasions, also known as monorail vehicles or monorail bicycles. The current urban monorail vehicle traffic mainly adopts the straddle type monorail riding method. There are three types of wheels on the monorail vehicle bogie: running wheels, guide wheels and stabilizing wheels. During the operation of the train, the running wheels are always in contact with the top surface of the track beam, and the guiding wheels and stabilizing wheels play a role in buffering the lateral vibration of the vehicle. If there is no displacement of the bogie at the equilibrium position, the guide wheels and the stabilizing wheels will roll forward with the effective radius. The and stabilizing wheels will be subjected to radial pressure from the side of the track beam, which will force the bogie back to its equilibrium position. The running characteristics of the straddle-type monorail vehicle will make the track beam bear a large torsional load. For straddle monorail bicycles used in transportation, considering the characteristics of the above-mentioned mechanisms, the track needs to be designed with a certain height and width to meet the load strength of the rail vehicle, and the existence of such a track will inevitably increase the cost and installation difficulty.

Monorail has the characteristics of small footprint and simple construction, so it is mostly used in track-type automatic guided vehicles in logistics and straddle-type monorail bicycles in traffic, but the monorail track has a certain height, so as to meet The rail car straddles and rides on the track, and laying a certain height of monorail on the running track will inevitably affect the structure of the site where the rail car is located. The installation and laying of the monorail will block the original road and affect the construction vehicles. Traffic also affects the layout and reuse of the site.

To sum up, the existing railcars have the technical problems of high requirements on the ground and site, poor environmental adaptability, and limited scope of application.

In the present embodiment, the monorail track (1) adopts the "I" shape design, and the track is made of magnesium-aluminum alloy material, and the monorail track (1) is installed above the ground for railcar riding; the double-track track (2) The standard "light rail" is adopted, laid in the ground, with a 2mm high end surface exposed, and the double-track track (2) is laid on the road section that requires high-load vehicles to be rolled, and is used for railcar driving. At the switching point of the single-track and double-track tracks, the two tracks have a certain overlapping area, which is convenient for the railcar to run smoothly on the single-track and double-track track switching.

In the running part of the rail car body, it is divided into a single-rail guide wheel, a single-rail driving wheel and a combination of a double-rail driving wheel.

In this embodiment, the monorail guide wheels (13, 14) and the monorail driving wheels (7) are designed in two rows at the front and back. There are eight monorail guide wheels installed in two rows (four of which are left and right guide wheels (13), and four are up and down guide wheels (14)), of which there are four monorail guide wheels in each row, and two are left and right guide wheels of the monorail track. guide, the other two are the upper and lower guides of the monorail track, the surface of which is coated with polyurethane, and there is a certain gap between the left and right guide wheels (13) and the outer side of the monorail track (1) to adapt to the curvature of the track, the size of the gap and the curvature of the track Proportional; Up and down guide wheel (14)) and the lower end of monorail track (1) upper end surface also respectively has certain clearance, prevents car body rollover, and guide wheel does not have driving force, is follow-up mechanism. In the present embodiment, there are two monorail driving wheels (7), which run on the upper end face of the monorail track (1), and the width of the monorail driving wheel (7) is slightly narrower than the upper end face width of the monorail track (1).

Double-track driving wheel (8) is also designed for two rows before and after, and every row of double-track driving wheel (8) has two, and the inboard of double-track driving wheel (8) has rigid track rib (16), is used for double-track driving wheel ( 8) be stuck on the double-track track (2) when driving, and the width of the double-track drive wheel (8) is slightly narrower than the width of the double-track track (2) rail surface.

The rail car body is driven by two drive motors (12), each motor drives a transmission rod (6) through a sprocket and a chain (3), and each transmission rod (6) drives a drive rod (6) through a monorail transmission chain (4). The single-track drive wheel (7), drives two double-track drive wheels (8) of the same row by two double-track transmission chains (5). The driving motor (12) and the transmission rod (6) regulate the tightness of the chain through the chain adjusting thimble (15) respectively, so as to reach a suitable transmission degree.

When the track is designed, the curve is designed on the single track, and all double track tracks are straight tracks. When the car body travels to a curve, the clearance of the guide wheels meets the curvature of the curve, so as to ensure that the car body moves forward smoothly.

As shown in Figure 4, when the car body is running on the monorail track (1), the monorail guide wheels (13, 14) and the monorail drive wheel (7) guide the monorail track (1), drive the car body to move forward, and the double track drive wheels (8 ) is now suspended in the air; when the car body travels to the single and double track switch, the monorail guide wheels (13, 14) and the monorail drive wheel (7) are guided on the monorail track (1), and simultaneously, the double track drive wheel (8) is on the double track Guided on the track (2), the single and double track driving wheels have driving force to drive the car body; , monorail guide wheel (13,14) and monorail driving wheel (7) are suspended in the air, and the double-track track (2) that finishes car body has monorail track (1) travels to switch. When the car body travels from the double-track track to the single-dual-track switching place and thus travels to the single-track process, it is the above-mentioned reverse process, which will not be repeated here.

The above is only a preferred implementation example of the present invention, and is not intended to limit the present invention in any form, any content that does not deviate from the technical solution of the present invention, any simple modification made to the above implementation examples according to the technical essence of the present invention , equivalent changes and modifications all belong to the scope of the technical solution of the present invention.
