Truss type erecting arm

Abstract

The invention discloses a truss type erecting arm. The truss type erecting arm comprises a lower left main beam, a lower right main beam, an upper left main beam, an upper right main beam, an erecting cross beam, a rear main support, a front main support and a plurality of first assisting beams, wherein the lower right main beam and the upper right main beam are connected through vertical beams and inclined beams; the lower left main beam and the upper left main beam are connected through the vertical beams and the inclined beams; two ends of each first assisting beam are respectively and perpendicularly connected with the lower right main beam and the lower left main beam; the front main support, the erecting cross beam and the rear main support which are used for supporting a product are respectively sequentially fixedly connected from the front half parts to the tail ends of two lower main beams; the whole erecting arm is of a concave frame structure, and the longitudinal section of the concave shape is reversely trapezoidal. The erecting arm of the truss type double-layer main beam structure is simple and reliable in overall structure and can bear bending torque, erecting torque, and axial pulling force or pressure; the inclined beam is adopted, so that the material is saved, the dead weight is reduced, the rigidity is increased; the bending resisting section is high; large-ton reliable bearing is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted thermal launch of weapons, in particular to a truss-type erecting arm. Background technique [0002] In the field of weapon vehicle-mounted thermal launch technology, during the process of product parking, transportation, erection and return, a device is needed to drive the product to complete the erection and fall actions, support the product and bear inertial loads such as product gravity. The vertical arm can realize the above functions, but the current commonly used vertical arm has the following problems: [0003] a) At present, the vertical boom generally adopts a single-layer main beam structure, which basically relies on the section of the main beam to bear the load. Under the condition of heavy load, the section size of the main beam is required to be high, which will easily lead to a large structural weight. In order to avoid the structure being too bulky, The main beam on one s...

Problems solved by technology

[0008] The purpose of the present invention is to provide a truss-type erecting arm to solve the problem that the existing structure is too bulky, and the shape and size of each part are mostly irregular. The gap between the erecting arm and the transported products is large, resulting in waste of space and is not conducive to equipment Problems with the layout of other systems of the cabin class vehicle
