Problems solved by technology

However, although the existing controllable mechanism loaders replace the hydraulic transmission with the link mechanism, which solves some deficiencies in the hydraulic system, the bearing capacity is low, and it is often only suitable for small or medium loaders. Some mechanical loaders The transmission part of the connecting rod is complex, and the number of rods is too large, resulting in excessive self-weight, poor dynamic performance, and excessive motion inertia

Abstract

The invention relates to a controllable-mechanism type heavy-duty loader with high bearing capacity, which comprises a double-large-arm mechanism, a large arm lifting branch chain, a bucket overturning branch chain, a bucket, a travelling device and a stand, wherein the stand is arranged on the travelling device; the double-large-arm mechanism is articulated on the stand, and the other end of the double-large-arm mechanism is articulated with the bucket; the large arm lifting branch chain is used for controlling large arms to ascent and descend; the bucket overturning branch chain is used for controlling the bucket to overturn; the large arm lifting branch chain and the bucket overturning branch chain are respectively driven by a servo motor arranged on the stand; and the large arm lifting branch chain is matched with the bucket overturning branch chain, so that the loading operation of the heavy-duty loader can be completed. The controllable-mechanism type heavy-duty loader with high bearing capacity not only overcomes the defects that a hydraulic element of the traditional hydraulic loader is high in manufacturing cost, complicated in maintenance and the like, but also is compact in structure, less in the number of rod pieces, high in bearing capacity and reliability, and strong in shock resistance compared with other controllable-mechanism type loaders, and the large heavy-duty loader manufacture is facilitated.

Description

Technical field [0001] The invention relates to the field of engineering machinery, in particular to a controllable mechanism type high-loading capacity heavy loader. Background technique [0002] Loader is a kind of earthwork construction machinery widely used in highway, railway, construction, hydropower and other construction projects. It is mainly used for shoveling bulk materials such as soil, sand and gravel. It can also be used for light shoveling of ore and hard soil. operation. Different auxiliary working devices can also be used for bulldozing, lifting and other materials loading and unloading operations. Hydraulic loaders are the most widely used type of loaders, but the maintenance of the hydraulic system is complex, and the cost is high. The hydraulic system is easily affected by environmental factors, especially in low temperature or high temperature environments, which are prone to weakness or vibration. [0003] With the development of numerical control technology...
