Description

Technical Field

[0001] This invention relates to a power bogie for a suspended monorail engineering vehicle, which belongs to the technical field of transportation engineering vehicles. Background Technology

[0002] The modernization of urban transportation is a concrete manifestation of urban modernization. Currently, commonly used highway, light rail, subway, and railway transport vehicles can meet the needs of cities to travel on highways and railway standard gauge lines. In order to reduce the investment in urban infrastructure funds, for cities with mountainous and hilly terrain, the transportation of elevated rail is an effective way with low investment in urban transportation.

[0003] With urban construction and development, suspended monorail transportation has entered the urban transportation system, providing a new option for transportation in mountainous and hilly cities. The characteristic of suspended monorail lines is that the drive unit needs to be installed within a square tunnel, with the operating vehicles suspended below. Given these characteristics, a power bogie assembly and suspension frame assembly is needed that meets the requirements for daily maintenance, major and minor repairs, and emergency rescue of suspended monorail lines, while also being suitable for the installation and use of suspended monorail engineering vehicles, to ensure the safety of the suspended monorail lines during use and construction. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a power bogie for a suspended monorail engineering vehicle. Its objectives are: 1. To provide a traction power device for the suspended monorail engineering vehicle that relies on its own power battery, is environmentally friendly, pollution-free, and has zero emissions; 2. The power bogie assembly and suspension assembly meet the technical requirements of vehicle clearance and building clearance for suspended monorail lines; 3. The maximum operating speed set by the power bogie assembly and suspension assembly reaches the design requirement of 50 km / h; 4. To provide a comfortable and stable running condition for the engineering vehicle, meeting the safety conditions for use and driving; 5. Precise positioning of traction and parking brakes, with safety and stability meeting the requirements for construction use, emergency repair, and rescue.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: 1. The power bogie uses lithium iron phosphate batteries converted into AC power by an inverter to drive an electric motor, achieving full-process traction with environmental protection, zero pollution, and zero emissions; 2. Based on the technical requirements of suspended monorail lines, a special axle and bogie are designed to meet the guidance, travel, and hydraulic braking requirements of the suspended monorail along the inner wall of the open track; 3. According to the characteristics of suspended monorail lines, the power bogie assembly and suspension assembly adopt a box-type T-beam installation method, which meets the needs of vehicle suspension travel and curved driving; 4. The axle and the box-type T-beam are hinged at one end, and the upper end is assembled with the shock absorber and traction pin, effectively meeting the dynamic response, directional damping, and power traction requirements of the power bogie assembly for travel within the track; 5. Based on the special characteristics of suspended vehicle travel, the suspension assembly is designed in terms of suspension load, dynamic damping, and yaw limit, meeting the safety requirements for use and driving. This invention mainly includes bogie assembly, sway limiter shock absorber, and suspension frame assembly. The powered bogie is the running and suspension device of a suspended monorail engineering vehicle and is a key piece of equipment for such vehicles.

[0006] The bogie assembly consists of two axle assemblies with axle upper plates and four pneumatic tire wheels, two motor reducer assemblies, two upper guide mechanisms, two lower guide mechanisms, safety ropes, and suction pipe assemblies, which are installed on the T-beam assembly according to their functions.

[0007] Furthermore, the axle assembly is equipped with a brake system, and the gearbox fitted with the motor reducer is equipped with a parking brake to ensure the safety of the multi-functional work vehicle during travel and parking.

[0008] Furthermore, one end of the axle assembly is hinged to the T-beam welded by a traction pin, and the upper end is assembled with the engineering machinery shock absorber and traction pin to effectively meet the dynamic response, directional damping and power traction requirements of the power bogie assembly rail. Furthermore, a bogie assembly and a dedicated axle were designed to meet the requirements of guiding, traveling, and hydraulic braking of the suspended monorail along the inner wall of the air rail. Furthermore, the T-beam is welded with a motor reducer assembly to provide torque for the power bogie to travel within the rail assembly. Furthermore, based on the characteristics of suspended monorail lines, the power bogie assembly and suspension frame assembly adopt a box-type T-beam installation method, meeting the needs of vehicle suspension travel and curve driving. The T-beam welding adopts a T-shaped box beam structure, welded from steel plates. The bearing housing welding of the T-beam welding adopts a suspension pin assembly and a hinged suspension with the suspension frame assembly. The limit stop of the T-beam welding serves as a mechanical limit for the suspension swing angle. The lug pin suspension of the T-beam welding is equipped with a steel wire safety rope for the car body connection safety and anti-derailment function.

[0009] Four pressure-bearing bell-shaped shock absorbers are installed between the suspension frame assembly, which is hinged to the T-beam welded assembly, and the roof frame assembly. The bell-shaped shock absorbers are fixedly connected to the suspension frame welded assembly by hexagonal bolts, spring washers, and flat washers; the bell-shaped shock absorbers are fixedly connected to the roof frame assembly by hexagonal bolt pairs.

[0010] Furthermore, to ensure the flexible positioning, attitude adjustment, and limit of the suspension welding assembly, two stop B assemblies (mechanical limiters for the assembly of the bogie and suspension), two nylon bumper assemblies, and six PDR-5 shock absorbers are arranged diagonally in front, behind, left, and right of the suspension welding assembly and the roof frame assembly. Furthermore, the roof rack assembly, roof bracket A, and other components are equipped with four horizontally symmetrically arranged bracket pins and corresponding elongated slots for the roof bracket A. The bracket pins are fixedly connected by hexagonal bolt pairs. Furthermore, the suspension frame is integrally welded from structural steel plates, and it is equipped with two vent pipes that run through the front and rear. A coupler seat plate is welded to the front, and two limit posts are welded in the middle for installing nylon bumper assemblies on the left and right sides. The roof bracket A is integrally welded from structural steel plates, and the front and rear stop plates of the roof are equipped with pin holes for installing steel wire safety ropes.

[0011] The beneficial effects of this invention are: it can provide a traction power device for suspended monorail engineering vehicles that relies on self-contained power batteries and is environmentally friendly, pollution-free, and emission-free when there is no dedicated power supply for suspended monorail lines; the power bogie assembly-suspension assembly meets the technical requirements of vehicle clearance and building clearance for suspended monorail lines; the power bogie assembly-suspension assembly adopts a dual braking method of hydraulic braking and electromagnetic braking to meet the needs of precise positioning for traction and braking, and the designed maximum operating speed reaches the requirement of 50km / h; the dynamic shock absorption performance and safety stability performance of the power bogie assembly-suspension assembly meet the requirements of construction, emergency repair, and rescue for suspended monorail engineering vehicles.
