Articulated device and heavy-duty bracket transporter

Abstract

The invention discloses an articulated device and heavy-duty bracket transporting vehicle. The articulated device comprises a first hinge frame. A plurality of first ear plates spaced apart along a width direction and a plurality of second ear plates spaced apart along a height direction are respectively arranged on two sides of the first hinge frame. A second hinge frame, wherein the second hingecomprises a first connection part and a second connection part, the first connection part and the second connection part are respectively connected with the tractor through a pin shaft and with a plurality of the first lug plates through a first pin shaft; a third hinge frame including a third connection portion and a fourth connection portion, the third connection portion and the fourth connection portion being connected with the plurality of second lug plates through a second pin shaft and with the trailer through a pin shaft, respectively. The invention provides a articulated device and aheavy-load bracket transporting vehicle, which improves the flexibility, stability and firmness of the articulated device, so as to adapt to different road conditions, reduce the difficulty of consignment and increase the consignment speed.

Description

technical field [0001] The present invention relates to heavy-duty support conveying equipment, and more specifically, to a hinged device and a heavy-duty support transport vehicle. Background technique [0002] The heavy-duty support truck is a vehicle used to transport hydraulic supports in coal mines. It belongs to heavy mechanical equipment in coal mines. The handling efficiency of the heavy-duty support truck directly affects the continuous working time of the working face. [0003] Existing heavy-duty support trucks include tractors and trailers. The tractors are used to provide the traction required for vehicle operation. The trailers are used to carry the brackets. The tractors and trailers are connected through hinged devices. Passed to the trailer to move the trailer and the heavy-duty frame above it. There are a large number of heavy-duty brackets and heavy weight, which puts forward higher requirements on the flexibility and firmness of the hinged device. The e...

AI Technical Summary

Problems solved by technology

The existing articulated device usually adopts the shaft hole structure, because the structure is too simple, which is not conducive to the effective transmission of traction force; and the connection strength and stability are limited, and the underground environment is complex, especially the ground may be ups and downs, and the heavy-duty support truck is in motion. It may even slip off and cause safety accidents at the undulating part of the ground, which brings great difficulties to the effective use of the heavy-duty support truck and becomes the main restricting factor affecting the moving speed of the heavy-duty support truck.
