Embodiment Construction

[0019] see Figure 1 to Figure 8 As shown, this embodiment is composed of a main body load-bearing structure 1 and an induced buffer structure 2. The main body load-bearing structure 1 is formed by connecting four columns 11 with upper and lower beams 12, 13 through flanges 14. The main body load-bearing structure 1 The left and right sides, the front and the back, and the upper and lower sides are all in the shape of a curved trapezoid. The four columns 11 are equal-strength columns, and their axes are curved. into; the left and right sides, the front, the back and the top of the induced buffer structure 2 are all in the shape of a curved trapezoid. The front column 25 is respectively welded at the intersection of the left and right crossbeams 21, 27 and the front crossbeam 28 to form the frame of the induced buffer structure. In the trapezoidal frame, several longitudinally curved round steel pipes 24 and several transverse round steel pipes 23 are cross-welded together, and...

Abstract

The invention discloses a buffer-induced independent combined-type roll-over protection structure, which consists of a main-body bearing structure and a buffer-induced structure, wherein the main-body bearing structure is formed by connecting four upright columns with an upper beam and a lower beam through flanges; the main-body bearing structure is in a curved-edge trapezoidal shape in the left-right, front-back and upper-lower surfaces; the buffer-induced structure is in a trapezoidal shape; the buffer-induced structure is in the curved-edge trapezoidal shape in the left-right, front-back and upper surfaces; the upright column of the buffer-induced structure and the upright column of the main-body bearing structure are connected with bolts though transition fit; the lower end of the upright column of the buffer-induced structure is welded with a curved pipe; the curved pipe is inserted into the upright column of the main-body bearing structure and is fixed through the bolt throughout the two; and the main-body bearing structure and the buffer-induced structure are arranged outside a cab and are connected with a vehicle frame through the flanges. The protection structure has the advantages of taking the flanges for connection to ensure convenient replacement and maintenance, short maintenance cycle and lower maintenance cost, along with strong capability of resisting deformation and absorbing the kinetic energy of roll-over.

Description

technical field [0001] The invention relates to a rollover protective structure, in particular to an induced buffer independent combined rollover protective structure. Background technique [0002] When an existing engineering vehicle with a rollover protection structure rolls over, the driver's cab is easily deformed, resulting in a greatly reduced space in the driver's cab, leaving no living space for the driver. To this end, the industry has designed a rollover protection structure. The existing safety cab type rollover protection structure integrated with the driver's cab is expensive to design and manufacture, and it cannot be realized on large vehicles; in addition, the external rollover protection structure is generally Fixed and non-detachable, the cost of repair and replacement after damage is relatively high, and there is a contradiction between the load-carrying capacity of the existing rollover protective structure and its energy absorption, that is, the load-car...
