Problems solved by technology

[0004] Especially when the catenary suspension transitions from the rigid suspension of the underground shield section to the flexible suspension of the viaduct section, the maximum height difference of the contact wires reaches 600mm, and it is difficult for a ladder car with a fixed structural height to meet the requirements in this section. Work requirements
[0005] In addition, since urban rail transit lines are usually fully enclosed, and the nighttime maintenance and overhaul of main line catenary equipment is particularly limited

Embodiment Construction

[0028] Such as Figure 1~5 As shown, an urban rail transit catenary intelligent electric ladder car consists of three parts: a chassis 1, a car ladder 2 installed on the chassis 1, and a working platform 3 installed on the top of the car ladder 2.

[0029] Such as image 3 As shown, the chassis 1 mainly consists of a pair of coaxial motor wheels 6 with the crossbeam 4, a pair of coaxial driven wheels 7 with the crossbeam 4, and a chassis platform 5 connecting the two crossbeams 4; a storage box 8 is arranged on the chassis platform One, one power supply box 9, four lighting fixtures 10; 11 handrails are respectively arranged at the front and rear ends of the platform, which is convenient for carrying and can also be used as a pedal when the operator transfers by a ladder car.

[0030] Such as Figure 4 As shown, the car ladder 2 is mainly composed of two car ladder bodies 13 at the front and rear, and is assembled into the overall structure of the car ladder through four hig...

Abstract

The invention discloses an intelligent electric ladder trolley for an urban rail transit contact network. The intelligent electric ladder trolley comprises three parts, namely a chassis, a trolley ladder arranged on the chassis and a work platform arranged at the top of the trolley ladder. The ladder trolley is respectively provided with one power supply box arranged on the chassis, one pair of motor wheels arranged at the two ends of a cross beam of the chassis and one scissor fork type lifting operation platform driven by a hydraulic pump. Intelligent operation is carried out by virtue of acontrol terminal arranged at the middle part of the trolley ladder, so that an automatic fast advancing function of the ladder trolley can be realized, and an automatic lifting function of the work platform of the ladder trolley also can be realized. The intelligent electric ladder trolley disclosed by the invention has the advantages of high advancing speed, strong load transferring capability, intelligent operation, diversified functions, and simple structure and is convenient to disassemble, assemble and transport.

Description

technical field [0001] The invention relates to an intelligent electric ladder car for an urban rail transit catenary. Background technique [0002] The catenary operation ladder is an essential and important equipment in the construction of urban rail transit catenary projects and the maintenance and repair of catenary equipment. [0003] Contact suspensions in different sections or different installation forms usually have different wire heights, so the structural height requirements for catenary work ladder trucks will also be different. [0004] Especially when the catenary suspension transitions from the rigid suspension of the underground shield section to the flexible suspension of the viaduct section, the maximum height difference of the contact wires reaches 600mm, and it is difficult for a ladder car with a fixed structural height to meet the requirements in this section. Work requirements. [0005] In addition, since the urban rail transit lines are usually full...
