Description

Special working vehicle for monorail traffic

Technical field

The utility model relates to a working platform used for repair and maintenance of track beams, turnouts, tunnels and facilities such as power supply and communication signals along the line, and provides transportation, lighting and maintenance work platforms for maintenance workers.

Background technique

With the advancement of science and technology and the development of economy, the pace of national industrialization has accelerated, leading to a sharp increase in urban population. The traditional mode of transportation can no longer meet the requirements of urban development. The ever-expanding cities need a light, fast, green and environmentally friendly means of transportation. Subway and light rail are an ideal choice. The monorail system is a branch of the light rail system. The monorail transit system has the advantages of fast operation speed (maximum operation speed 100km/h), small investment (1/5~1/2 of the subway), small footprint, flexible operation lines, good environmental protection performance, etc., and is more and more popular in cities. Favored by the transportation department, it is especially suitable for cities with complex terrains. In recent years, my country has only developed monorail transportation systems. Fast, comfortable and pollution-free urban rail transit is the direction of future urban traffic development. The monorail system needs special maintenance equipment, but there is still no working vehicle dedicated to the monorail system in China. This device is developed based on this.

Contents of utility model

The utility model relates to a track beam, turnout, tunnel and the repair and maintenance of facilities such as power supply and communication signals along the line, and can be used for rescue of other faulty working vehicles and can be used as a cantilever crane trailer, limit inspection vehicle, and vehicle depot. It is a traction vehicle for monorail vehicles and provides a working platform for transportation, lighting and maintenance for maintenance workers.

The technical solution designed by the utility model to solve the above problems is:

The car consists of a driving platform, a car body assembly, a frame assembly, an air system, a chopper control device, a disc brake assembly, a traction coupler, a battery pack, a guide wheel assembly, a stabilizing wheel assembly, an auxiliary Wheel assembly, track side maintenance work platform, running wheel assembly, driving device, DC traction motor, track top maintenance work platform, lighting and alarm devices, guardrails and escalators, etc. The vehicle is driven by a DC traction motor, and the electric transmission adopts a two-phase non-heavy DC chopper voltage regulation and speed regulation system, with traction and braking control functions. The traction working condition adopts constant current acceleration and full pressure operation. The braking working condition adopts cross-excitation circuit, which is regenerative-resistance energy consumption composite braking.

The effect of the utility model is that it can freely and conveniently walk, park, and transport maintenance workers and equipment and materials required for maintenance on the PC track beam. It can reliably fix itself on any part of the track, and can provide a safe working site and lighting and other working conditions for maintenance workers. It can be used as a towing vehicle for other vehicles.

Detailed ways

Further explanation below in conjunction with accompanying drawing (Fig. 1, Fig. 2):

The working vehicle includes a driving platform 1, a vehicle body assembly 2, an underframe assembly 3, an air circuit system 6, a chopper control device 7, a guide wheel assembly 17, a stabilizing wheel assembly 18, an auxiliary wheel assembly 19, and a running wheel Assembly 21, track top surface overhaul operation platform 24. Lighting and alarm device 11, guardrail 13, escalator 14. It is characterized in that there are inner driving doors 5 on both sides of the car body that can enter and exit the platform, and inner driving doors 12 that can enter and exit the trailer at both ends of the car body, and a manual door for maintenance in the tunnel is provided on the top of the car body. The sliding door 4 of opening and closing. A disc brake assembly 8, a driving device 22, and a DC traction motor 23 are installed at both ends of the two traveling wheel shafts 9, respectively. Battery packs 16 are installed at both ends of the underframe, a track side maintenance work platform 20 is installed at the middle part of both sides of the underframe, and a track top surface maintenance work platform 24 is installed at one end both sides of the underframe. A traction coupler 10 is installed in the middle part of both ends of the underframe.

When the work vehicle is walking on the track beam 15, use the traveling wheel assembly 21 to walk on the top surface of the track beam 15, use the guide wheel assembly 17 to guide on the side of the track beam 15, and use the stabilizing wheel assembly 18 to guide and stabilize on the side of the track beam 15. .

The working vehicle is provided with DC power by the battery pack 16, and the electric energy is transmitted to two DC traction motors 23 through the chopper control device 7, and the power is transmitted to the running wheel assembly 21 through the driving device 22, and drives the working vehicle to the track that needs maintenance lot. When the vehicle decelerates, the traction motor operates as a generator through the conversion of the electrical circuit, converting the kinetic energy of the vehicle into electrical energy, part of the electrical energy is charged to the battery, and the excess electrical energy is consumed on the resistance grid, so that the dump truck can obtain proper braking force. Utilize the disc brake assembly 8 to brake, so that the working car is parked on the required track section. Maintenance workers utilize ladders to enter the track side maintenance work platform 20 or the track top surface maintenance work platform 24 to carry out various operations, such as facilities such as maintenance track beams, tunnels, power supply lines, communications, and signals. The work vehicle can transport maintenance workers and provide them with a safe working place and lighting and other working conditions. The working vehicle can also carry out various operations by pulling the cantilever crane trailer or the limit inspection car through the traction coupler 10. It can also be used as a rescue vehicle for breakdown work vehicles or monorail vehicles.
