In the attached drawing, the device comprises a buffer strip 1, a buffer strip 2, a metal ball 3, a first horizontal box body 4, an inclined box body 5, a second horizontal box body 6, a connecting box body 7, a rubber support 8, a backing plate 9, a spring buffer 10 and a clamping plate.

Detailed Description

As shown in fig. 1-3, the utility model provides a box girder type buffer bed for a conveying system, which comprises a support frame, an installation seat arranged at the lower end of the support frame and a buffer strip 1 arranged at the upper end of the support frame, wherein the cross section of the support frame is of a C-shaped structure with an upward opening, the support frame is formed by splicing a plurality of hollow box units, and metal balls 2 are filled in the box units.

After the atress, buffering strip 1 is the rubber material, plays the first buffering, and the support frame produces vibrations after receiving the impact force of buffering strip 1 transmission, and the earlier atress of partial metal ball 2 in the box unit, then with other metal ball 2 bumps, with impact force conduction, dispersion, play the second time buffering, this structure adopts hollow box unit, compares solid steel frame construction, equal proportion high load, the torsional rigidity in cross-section is bigger.

As shown in fig. 2, the box unit includes a first horizontal box 3 and inclined boxes 4 disposed at both sides of the first horizontal box 3, and the first horizontal box 3 and the inclined boxes 4 are connected to form a C-shaped structure.

The box body unit adopts a sectional compartment structure, and multipoint stress is dispersed after the box body unit receives impact force, so that the buffering effect is further improved.

As shown in fig. 2, at least two inclined boxes 4 are provided on one side of the first horizontal box 3.

The metal ball 2 is not full of in the box unit, just can realize the effect of conduction and dispersion, under the prerequisite that is not full of, two slope boxes 4, can avoid on the corner of the whole gathering bottom of metal ball 2 in the slope box 4, other positions are too empty, and can't play fine buffering effect.

As shown in fig. 2, a second horizontal box 5 is arranged on the inclined surface of the lower end of the inclined box 4, and the lower end of the second horizontal box 5 is connected with the mounting seat.

The second horizontal box 5 is filled with metal balls 2, and impact force is transmitted to the mounting seat after being dispersed and transmitted to the second horizontal box 5 through the first horizontal box 3 and the inclined box 4, so that the transmission dispersion time and distance of the impact force are increased, and the buffering effect is further enhanced.
