Problems solved by technology

[0006] However, in the scraper type cantilever conveyor in the prior art, during the working process, the mineral materials contained in the front chute 01, the rear chute 02 and the two will exert a relatively large reaction moment on the lifting hydraulic cylinder 05.
Under the long-term action of the above-mentioned reaction torque, it is easy to cause the problem of pressure relief failure of the lifting hydraulic cylinder 05, which in turn creates a safety hazard for the job site
In addition, due to the large length of the frame body of the conveyor, and during the working process, the frame body is prone to bending under the action of the mineral material and its own gravity, and the frame body is prone to shaking problems during transportation. Especially the blanking end shakes the most, which leads to the problem of unstable blanking
[0007] In addition, in the scraper type cantilever conveyor in the prior art, the front chute 01 and the rear chute 02 are fixedly connected, and the angle between the rear chute 02 and the front chute 01 is a fixed angle, so the positions of the current chute 01 and the rear chute 02 are lifted upwards At the same time, the position of the discharge end of the rear chute 02 is relatively high, which in turn makes the position of the mineral material drop point higher. When the mineral material falls onto a large mining truck, it will cause a greater impact on the truck, thereby affecting the life of the mining truck.
[0008] Therefore, how to solve the problem of pressure relief failure of the lifting hydraulic cylinder of the conveyor and the instability of the frame body has become an important technical problem to be solved by those skilled in the art

Abstract

The invention discloses a cable-stayed cantilever conveyor, which comprises a frame body with a rear frame and a front frame. There is a lifting hydraulic cylinder, which also includes a first tensioning device and a first tensioning adjustment device fixedly arranged on the rear frame or connected to the turntable, the first wire rope tensioner is arranged between the rear frame and the connection to the turntable, and The moment direction of the moment applied to the rear frame by the first tensioning device of the first wire rope is the same as that of the lifting hydraulic cylinder applied to the rear frame. With such arrangement, the cable-stayed cantilever conveyor disclosed in the present invention can effectively avoid the failure of pressure relief of the lifting hydraulic cylinder, and its frame body has better stability.

Description

technical field [0001] The invention relates to the field of engineering machinery, and more specifically relates to a cable-stayed cantilever conveyor. Background technique [0002] my country's economic construction has achieved rapid development in recent years, and economic development is inseparable from the exploitation and utilization of natural energy. In the mining process of coal mines, mines and engineering tunnels, due to geological conditions, the slope of the roadway is relatively large. In the mining process of coal mines, mines and engineering tunnels, it is usually necessary to use a large-slope roadheader for construction operations, and the ordinary belt conveyor matched with the roadheader is in the process of transporting materials, due to the limitation of its own height adjustment, the ordinary belt conveyor The height cannot meet the loading requirements of large mining trucks. Therefore, how to make the conveyor meet the loading requirements of lar...
