Removable box cover on-off mechanism of oscillating arm type truck

Abstract

Disclosed is a cover opening / closing device for the removable cover of swinging truck, belonging to the art of goods transport. It contains a lower-beam two-end hinging with the cover, a pair of cover lifting devices fixed separately on the two ends of the lower-beam, an upper gyro-axle parallel with the lower-beam, a pair of chain seats fixed on the shaft end of the upper gyro-axle, a pair of cover turning devices connecting with the lower-beam and the covers, and a fixing guide device equipped between the lower-beam and the upper gyro-axle. It has merits as following: it can separate the whole cover into two-part connective clamshell shapes, and the space needing for opening and closing cover is almost ignorable; and the cover can be along with the removable box.

Description

technical field [0001] The invention belongs to the technical field of cargo transportation, and more specifically relates to a box cover opening / closing mechanism arranged on a movable box cover of a swing arm transport vehicle. Background technique [0002] The swing-arm transport vehicle transports goods by means of movable boxes (customarily called buckets) configured on it. The movable boxes are used as containers for loading or turnover, and are widely used in construction, industrial and mining enterprises, sanitation industries, etc. and other industries. For example, iron and steel plants in industrial and mining enterprises are used to load scrap iron and cinders, and sanitation departments are used to load garbage. [0003] Since the previous movable case is not provided with a case cover (being customarily called a bucket cover), the opening / closing mechanism of the case cover is out of the question. When the movable box without box cover full of goods is suspe...

Problems solved by technology

But there are following obvious defects: one, the box cover 1 itself shows the structural form of the cantilever beam, and the whole box cover 1 is only hinged with the box wall of the sub-frame by hinges, and the connecting rod of the opening / closing mechanism has a long and slender span, and the receiving side It is easy to lose stability after the force and cause an accident; two, the opening / closing of the case cover 1 must have enough space and height protection, because in the actual opening / closing situation, the vehicle is often affected by other objects such as tree forks, It is difficult to open / close the cover due to the obstruction of overhead lines

Therefore, it is impossible to learn from the patented technical solution that it aims to solve figure 1 Technical inspiration for the technical flaws brought about by the lid opening / closing mechanism shown
