Embodiment Construction

[0028] A telescopic and folding material conveying device, such as figure 1 As shown, it includes a gantry frame seat and a conveying frame seat, a gantry frame 2 mounted on the gantry frame seat and a conveying arm hinged on the conveying frame seat; Folding turning mechanism 4; the delivery arm includes three booms, namely the main arm 6, the first telescopic arm 9 and the second telescopic arm 10; the first telescopic arm 9 can be extended or retracted relative to the main arm 6 , the second telescopic arm 10 can extend or retract relative to the first telescopic arm 9 . Between the gantry 2 and the main arm 6, as well as between the gantry 2 and the telescopic arms 9, 10 at all levels, there are devices that drive the main arm 6 and the telescopic arms 9, 10 at all levels to move closer to the gantry 2. Or separated main boom luffing mechanism 3 and rope wheel mechanism, the main boom luffing mechanism 3 is used to drive the main boom 6 to move closer to or separate from ...

Abstract

The invention discloses a telescopic folding type material conveying device and a transport ship. The conveying device comprises a portal frame seat, a conveying frame seat, a portal frame hinged to the portal frame seat and a conveying arm hinged to the conveying frame seat; a turnover mechanism for driving the portal frame to turn over towards the inner side is arranged on the inner side of the portal frame seat, and the conveying arm comprises a main arm and multiple stages of telescopic arms; retracting-stretching mechanisms for driving the main arm and the multiple stages of telescopic arms to get close to or be separated from the portal frame are arranged between the portal frame and the main arm and between the portal frame and the multiple stages of telescopic arms; and an arm rest telescopic mechanism for driving the multiple stages of telescopic arms to stretch out or retract back is arranged on the main arm. By means of the telescopic folding type material conveying device, the transport ship can pass through bridge openings in any shape, the safety performance is good, and space occupied by the folded portal frame and the folded conveying arm is small.

Description

technical field [0001] The invention relates to a telescopic and folding material conveying device and a transport ship, in particular to a sand and gravel conveying device including the functions of telescopic, flipping, luffing and conveying. Background technique [0002] There are two types of jib structures for self-unloading sand carriers: one is the integral jib form with fixed length, and the jib is turned over to the working angle of 0-20° in the operating state; the second is the folding arm jib, which is The whole body is flipped to the bow, and the jib does not protrude from the bow. [0003] For the first type of jib, the length of the jib is fixed, the position of the center of gravity is high during the flipping process, and the stability is not good. Once encountering strong wind or big water waves, it is easy to cause a rollover accident of the hull, and the bow jib after the flip is recovered If the height is too high, it will affect the sight of the boat a...
