Balance sliding device of block material loader

Abstract

The invention discloses a balance sliding device of a block material loader, which comprises an inner plate, a balance weight sliding plate group, a balance weight, a balance weight oil cylinder, a pressure sensor and a control system. The inner plate is installed on a vehicle frame, the balance weight sliding plate group is arranged on the inner plate of the vehicle frame in sliding mode, the balance weight is fixed on the balance weight sliding plate group and connected with the inner plate of the vehicle frame through the balance weight sliding plate group, the balance weight oil cylinder is installed on the inner plate of the vehicle frame, an oil cylinder rod of the balance weight oil cylinder is fixed on the balance weight, a pressure sensor for sensing cargo weight variation and the control system for controlling telescopic performance of the balance weight are further installed on the vehicle frame, cargo weight variation signals are fed back to the control system through the pressure sensor, the control system controls telescopic performance of the balance weight oil cylinder, and the balance weight oil cylinder drives the balance weight to stretch out and draw back. The balance sliding device of the block material loader can adjust distance of the balance weight automatically according to cargo weight, thereby adjusting minimum external turning radius of the block material loader automatically.

Description

technical field [0001] The invention relates to the technical field of block loaders, in particular to a balance sliding device for block loaders. Background technique [0002] A lifting vehicle with a lifting fork in front of the frame and a counterweight at the rear of the frame, referred to as a block loader. Block material loaders are suitable for loading and unloading, stacking and handling of finished items in ports, stations and enterprises. The frame is equipped with a power device (provides the original power), a transmission device (the original power is transmitted to the driving wheel), a steering device (controls the driving direction of the block loader), and a working device (the mechanism for lifting the cargo, also known as the door frame) , hydraulic system (fork lifting and mast tilting power supply device) and braking device. [0003] When the block loader is running at low speed without load and turning with the steering wheel fully turned, the minimum...

Problems solved by technology

[0004] However, when the block loader is suitable for large-tonnage goods, in order to realize the fork loading of large-tonnage goods, it is necessary to lengthen the wheelbase, affect the passability of the whole vehicle, or increase the weight of the counterweight and increase the cost

When the block loader is suitable for small tonnage cargo, since the position of the balance weight cannot be adjusted, the minimum outer turning radius of the block loader remains unchanged. In this way, even if the block loader is suitable for small tonnage cargo, the However, a larger ground area is still required, and the use range of the block loader is limited by the ground area, which makes it inconvenient to use, inflexible in action, and poor in maneuverability.
