Preferably, the cross section of described bending bracket is U-shaped structure, and the open end of U-shaped structure is arranged upward, and open end side level is provided with supporting plate, and described supporting plate is near the center of described car frame underbeam.
Preferably, be evenly distributed with more than two pieces welded plates in the groove of described U-shaped structure, described welded plate is vertical with described bending bracket.
Preferably, two or more Rubber shock-absorbing pad is provided with in the groove of described U-shaped structure.
Preferably, Rubber shock-absorbing pad is arranged near the two ends of bending bracket.
Preferably, the part described bending bracket contacted with described car frame underbeam is provided with two to above mounting hole.
Preferably, the upper and lower surface of described Rubber shock-absorbing pad is equipped with connecting panel, connecting panel is arranged with mounting hole, and Rubber shock-absorbing pad is fixed on bending bracket by the mounting hole on the connecting panel below it, is connected and fixed at the bottom of the mounting hole on the connecting panel above it and sedan-chair.
Preferably, the length of described bending bracket is less than the width at the bottom of sedan-chair.
Preferably, compressible stroke is the 15-25% of rubber thickness.
Compared with prior art, the utility model tool has the following advantages:
Can the actv. damping Problem of Failure that prevents the aging and super Rubber shock-absorbing pad compression limit of Rubber shock-absorbing pad from causing, change Rubber shock-absorbing pad in time.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and detailed description of the invention, the utility model is described in further detail.
Embodiment 1.
As shown in figs 1 to 6, a kind of elevator car bottom shock mitigation system, comprises two Rubber shock-absorbing pads 3 being horizontally set on the bending bracket 2 on car frame underbeam 1 side by side and being arranged in bending bracket 2.Bending bracket 2 is vertical with car frame underbeam 1, the height of Rubber shock-absorbing pad 3 is greater than the height of bending bracket 2, its height difference is compressible stroke Δ H, namely when Rubber shock-absorbing pad is aging or reach the pressurized limit, the supporting plate 21 that will be pressed onto bending bracket at the bottom of sedan-chair produces the slight metal bump sound, at this time will change Rubber shock-absorbing pad in time, thus make elevator be in good damping state always, ensure its stability run.
The cross section of bending bracket is U-shaped structure, and the open end of U-shaped structure is arranged upward, and open end side level is provided with supporting plate, and described supporting plate 21 is near the center of described car frame underbeam.
Be evenly distributed with three block welding plates 22 in the groove of U-shaped structure, welded plate is vertical with bending bracket.
Be provided with two Rubber shock-absorbing pads 3 in the groove of U-shaped structure, and Rubber shock-absorbing pad is arranged near the two ends of bending bracket 2.
The part that bending bracket 2 contacts with car frame underbeam 1 is provided with two pairs of mounting holes 4, is bolted.
In Fig. 4 and Fig. 5, the equal strong bond of upper and lower surface of Rubber shock-absorbing pad 3 has connecting panel 5 (being preferably steel plate or aluminium alloy plate), the two ends of connecting panel are respectively provided with a mounting hole 4, connecting panel is below secured by bolts on bending bracket, and connecting panel is above by being connected and fixed at the bottom of bolt and sedan-chair.
The length of above-mentioned bending bracket is less than the width at the bottom of sedan-chair.
Principle of work is shown in Fig. 6 and Fig. 1, when Rubber shock-absorbing pad is aging or reach the pressurized limit, bracket will be pressed onto at the bottom of sedan-chair and produces the slight metal bump sound, at this time will change cushion blocking in time, thus make elevator process good damping state always, ensure its stability run.Thus avoid changing in time the adverse consequences that cushion blocking brings.
