Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a large mine car boarding system that can be turned over by itself through on-board or off-board operation to solve the problem that the vehicle is lifted off the ground due to the increase in the size of the vehicle. The gap needs to be increased to maintain a large approach angle to maintain the vehicle passability and the conflict between the need for operators to get on and off the vehicle to meet the ergonomics requirements

Embodiment Construction

[0010] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

[0011] figure 1 Shown is the structural representation of the present invention.

[0012] The invention includes a boarding mechanism 1, a lifting cylinder 2, an electric pump 3, an electrical system 4, pipelines and wiring harnesses.

[0013] The boarding mechanism 1 is composed of a boarding ladder body 11 and a pin shaft 12. One end of the boarding ladder body 11 is hinged to the vehicle chassis. The piston rod is hinged, and the lifting cylinder 2 pushes the boarding mechanism 1 to turn around the hinge point between the boarding ladder body 11 and the vehicle chassis, so that the operator can smoothly board or get off the vehicle chassis, and after turning to the maximum angle, it will not affect Keep the ground clearance of the vehicle at a large approach angle.

[0014] The lifting cylinder 2 is an actuator, one end of which is hinged to ...

Abstract

The invention discloses a boarding system of a large mine car. The boarding system comprises a boarding mechanism, a lifting cylinder, an electric pump and an electric appliance system. The boarding mechanism comprises a boarding ladder and a pin, wherein one end of the boarding ladder is hinged to a car chassis, the lugs of the boarding ladder are hinged to the piston rod of the lifting cylinder through the pin, and the lifting cylinder pushes the boarding mechanism to turn over around the hinge point of the boarding ladder and the car chassis. The lifting cylinder is connected with a hydraulic one-way valve to allow the boarding mechanism hinged to the piston rod of the lifting cylinder to keep a certain turning-over angle. The electric pump powers the lifting cylinder. The electric appliance system is a control device. The boarding system has the advantages that an external power supply is used, the electric pump can be independently operated on or off the mine car, telescoping of the piston rod of the lifting cylinder is achieved through hydraulic oil, and the boarding ladder can turn over freely; the boarding and alighting function of the common boarding ladder is brought into play, and boarding and alighting postures conform to the requirements of ergonomics and large car ground clearance.

Description

technical field [0001] The invention relates to a large mine car boarding system, in particular to a large mine car boarding system that can be turned over by itself through on-board or off-board operation. Background technique [0002] With the development of the world economy, the scale of large-scale open-pit mines at home and abroad continues to expand, and the role of large-tonnage mining vehicles is prominent. Under the same output, large-tonnage mining vehicles can reduce the number of vehicles and drivers, which is easy to manage and improve Work efficiency and safety, and obtain higher economic benefits, so more and more mining areas order large-tonnage mining vehicles. In order to meet the needs of users, mining vehicle manufacturers continue to increase the load tonnage of mining vehicles. Correspondingly, their shape continues to increase, tires continue to increase, and the ground clearance of vehicles increases accordingly. People need to get on and off the veh...
