Preferably, being provided with around self the first circumferentially disposed semi-circular recesses on the first briquetting roller, the radius of the first semi-circular recesses is more than or equal to the radius of guard rail rod, and the distance at distance from bottom the first briquetting roller center of the first semi-circular recesses is equal to bending radius.
Preferably, being provided with around self the second circumferentially disposed semi-circular recesses on the second briquetting roller, the radius of the second semi-circular recesses is more than or equal to the radius of guard rail rod.
Preferably, the supporting surface that bearing upwardly extends along vertical direction and formed is curved, guard rail rod and supporting surface linear contact lay.
One according to the present invention is embodied as and preferred aspect, is being provided with multiple installing hole side by side along breaking on pole length direction, and the second briquetting roller can releasably be arranged in multiple installing hole on one.
Additionally, be fixed with extension breaking the bar end away from the first briquetting roller.Under identical stress, increase the arm of force, increase moment of torsion.
Due to the enforcement of above technical scheme, the present invention compared with prior art has the advantage that
The present invention moves bar, the second briquetting roller, the first briquetting roller and bearing guard rail rod is produced stress, makes guard rail rod flexural deformation, simple in construction rapidly, and it is convenient to implement, and cost is low.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described in detail:
Fig. 1 is the schematic top plan view of the flexural deformation device according to the present invention；
Wherein: 1, fixing seat；2, bearing；20, supporting surface；3, the first briquetting roller；30, the first semi-circular recesses；4, bar is broken；40, installing hole；5, the second briquetting roller；50, the second semi-circular recesses；6, guard rail rod；7, extension.
Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, the invention will be further described.
As shown in Figure 1, the flexural deformation device of the elevator guard rail rod that the present embodiment provides, it includes fixing seat 1, it is fixed on the bearing 2 on fixing seat 1, it is removably disposed on fixing seat 1 and horizontally disposed first briquetting roller 3, bar 4 is broken around what the first briquetting roller 3 rotated, it is removably disposed in and breaks on bar 4 and horizontally disposed second briquetting roller 5, wherein the first briquetting roller 3 and the second briquetting roller 5 lay respectively at the left and right sides of guard rail rod 6, bearing 2 and the second briquetting roller 5 are positioned at the same side of guard rail rod 6, when brake forming, move bar 4, second briquetting roller 5 makes the second briquetting roller 5 around the first briquetting roller 3 center to guard rail rod 6 left pivot movement, first briquetting roller 3, and guard rail rod 6 is produced stress and flexural deformation by bearing 2, and the bending radius of guard rail rod 6 is equal with the radius of the first briquetting roller 3.
In this example, the first briquetting roller 3 and the second briquetting roller 5 flush setting.
Concrete, first briquetting roller 3 is provided with around self the first circumferentially disposed semi-circular recesses 30, the radius of the first semi-circular recesses 30 is more than or equal to the radius of guard rail rod 6, and the distance at distance from bottom the first briquetting roller 3 center of the first semi-circular recesses 30 is equal to bending radius.
