Description

An electric telescopic forklift upper and lower train compartment device

technical field

The utility model relates to a device for getting on and off a train carriage by an electric telescopic forklift, which belongs to the technical field of railway transportation machinery.

Background technique

Railway transportation is a transportation mode in which fixed guide rails are used as transportation roads and vehicles are driven by rail machinery to transport passengers and goods. Railway transportation is an important mode of transportation suitable for medium and long-distance bulk passenger and cargo transportation. Railway transportation is an important mode of transportation in my country's transportation industry, and it is also the main mode of land transportation in most countries in the world. With the technological breakthroughs in heavy-duty transportation and high-speed trains, railway transportation has a more important position in the comprehensive transportation system.

Cargo loading and unloading is an important link that affects the speed of cargo transportation. There are problems such as high cargo loading and unloading intensity and high loading and unloading costs. The loading and unloading of train cargo generally adopts manual, crane, forklift loading and unloading and other methods. Manual loading and unloading is time-consuming, laborious, expensive, and inefficient, and cannot load and unload heavy objects; the crane has the disadvantage of poor flexibility due to its relatively fixed position with the train, and the initial investment is large, and the later maintenance costs are high; forklifts rely on their good mobility and easy maintenance. And the advantages of simple use are widely used in cargo handling. However, due to the large mass and volume of the forklift itself, and the height difference between the train carriage and the platform, each cargo station is equipped with a forklift, and a simple inclined bridge is manually built to realize the forklift getting on and off the train carriage. Because the connection part of this simple inclined bridge is not fixed, the reliability is not high, which increases the safety hazard during the use of the forklift. In addition, it is time-consuming and labor-intensive to build and dismantle the inclined bridge, which seriously affects the efficiency of cargo loading and unloading.

One motor realizes its own overturning, and another motor is used to drive the screw nut pair to realize the expansion and contraction of the parallelogram telescopic mechanism, and then drive the transition plate to expand and contract, which can realize the transition of different inclination angles between the train carriage and the platform.

The technical solution adopted by the utility model to solve its technical problems includes: motor I, pin I, pin II, connecting seat, motor II, lead screw, nut moving parts, bearing, parallelogram telescopic mechanism, transition plate I, transition plate II , Transition plate III, transition plate IV, fastening screws. The motor II is fixed on the vertical plate of the connection seat through fastening screws; one end of the screw is connected to the output shaft of the motor II through a coupling, and the other end is connected to the connection seat through a bearing; the moving part of the nut cooperates with the lead screw to form a screw. Bar nut pair; transition plate Ⅰ is fixed together with the connecting seat through fastening screws; transition plate Ⅱ and transition plate Ⅰ are clearance fit, which can move in transition plate Ⅰ; transition plate Ⅲ and transition plate Ⅱ are clearance fit, It can move in the transition plate II; the transition plate IV and the transition plate III are clearance fit, and it can move in the transition plate III; a connecting rod at the lower end of the parallelogram telescopic mechanism is hinged together with the connecting seat through a pin, and can be wound around the pin Rotate; another connecting rod at the lower end of the parallelogram telescopic mechanism is connected with the nut moving part, and the end of the connecting rod cooperates with the chute on the connecting seat through a small roller to guide the movement of the nut moving part; the parallelogram telescopic The two connecting rods at the upper end of the mechanism are connected with the chute of the transition plate IV through small rollers; the connecting seat is fixedly connected with the pin I and pin II, and the pin I and pin II are hinged with the train carriage, and the connecting seat can be connected with the pin I and pin II.
