Detailed description of the invention

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.

In Fig. 1 ~ Fig. 9, comprise traction handle 1, link rod bolt 2, guide pillar conduit tube component 3, brake beam 4, ratchet 5, axletree 6, otic placode 7, nut 8, bearing pin 9, band tooth brake facing 10, wheel 11, brake facing tooth 12, screw rod 13, adapter 14, movable joint head 15, guide pillar 16, screw thread 17, conduit 18, bolt 19, arc 20, circular hole 21 etc.

As Fig. 1, shown in Fig. 2, the present invention is the static brake equipment of a kind of flat truck, generally be arranged on the front vehicle wheel of flat truck, it comprises wheel 11, axletree 6 and traction handle 1, axletree 6 is arranged between two wheels 11, the inner side of two wheels 11 is fixed with ratchet 5 respectively, traction handle 1 is hinged on axletree 6 by two hinge-points, traction handle 1 is hinged with two link rod bolts 2, the other end of two link rod bolts 2 is hinged on brake beam 4 respectively, brake beam 4 is parallel to axletree 6, two cover guide pillar conduit tube components 3 are furnished with between brake beam 4 and axletree 6, the two ends of brake beam 4 are fixed with the band tooth brake facing 10 matched with corresponding ratchet 5 respectively.

As shown in Figure 3, link rod bolt 2 comprises screw rod 13, adapter 14 and movable joint head 15, and screw rod 13 and movable joint head 15 are separately fixed at the two ends of adapter 14.

Again see Fig. 1, Fig. 2, brake beam 4 is fixed with two pairs of otic placodes 7, is connected with bearing pin 9 rotationally between often pair of otic placode 7, as shown in Figure 8, Figure 9, bearing pin 9 has circular hole 21, the screw rod 13 of link rod bolt 2 passes circular hole 21 and is fixed by the nut 8 being positioned at circular hole 21 two ends.

As shown in Figure 4, Figure 5, guide pillar conduit tube component 3 comprises guide pillar 16 and conduit 18, and guide pillar 16 is slidably fitted in conduit 18.The fixed end of guide pillar 16 is processed with screw thread 17, and guide pillar 16 is connected on brake beam 4 by the nut be threaded on screw thread 17; The fixed end of conduit 18 is fixed with bolt 19, and conduit 18 is connected on axletree 6 by the nut be threaded on bolt 19.Locking when guide pillar conduit tube component 3 can prevent vehicle operating effectively, increases system sensitivity.
