Wherein, the brake eccentric is set in mounting base with being able to rotate by installation axle, and the part wheel of the brake eccentric
Friction teeth is offered on face, one end of the bar-link drive connects brake eccentric, and the other end connects hand log line, the survey
Speed detector is come on speed rope, riser guide is set to the side of the brake eccentric, and speed detector detects survey
Emergency braking hand log line when the decrease speed of speed rope is greater than the set value, bar-link drive drive brake eccentric rotation to make to rub
Tooth contact riser guide brakes.
Particularly, cylinder boss is provided on the lateral surface of the brake eccentric, the installation axle passes through the cylinder
Boss is arranged, and the side on the brake eccentric close to riser guide is equipped with limited block, the fixation by fixing bundle band
Band is around the cylinder boss and its both ends is fixedly connected on the upper and lower end of limited block, offers on the limited block along height
The guide groove of direction arrangement is spent, the brake eccentric is set in guide groove, cooperates the limited block in the mounting base
It is provided with spacer pin.
Particularly, the centering type brake insurance institution has two sets along short transverse arranged for interval, two sets of centering type brakes
Insurance institution shares a set of bar-link drive.
Particularly, the bar-link drive includes upper triggering connecting rod, lower triggering connecting rod and rotating bar, and the upper triggering connects
The upper end of bar is articulated on the brake eccentric for a set of centering type brake insurance institution being located above, the lower triggering connecting rod
Lower end is articulated on the brake eccentric of underlying a set of centering type brake insurance institution, the bottom of the upper triggering connecting rod
End, the top of lower triggering connecting rod and one end of rotating bar are coaxially hinged, and the middle part of the rotating bar is installed on by articulated shaft to be turned
On pole socket, the other end is articulated on hand log line.
Particularly, the outer end of the installation axle is equipped with caging bolt.
Beneficial effects of the present invention are that the centering type brake insurance institution is stopped using connecting rod driving compared with prior art
The brake modes of vehicle eccentric wheel, it is not only compact-sized under the premise of guaranteeing the stabilization and reliability of brake, it is ingenious in design；And
And small in size, at low cost, stable and reliable operation.
Detailed description of the invention
Fig. 1 is the schematic perspective view for the centering type brake insurance institution that the specific embodiment of the invention provides；
Fig. 2 is the partial enlarged view in Fig. 1 at A.
Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
It please refers to shown in Fig. 1 and Fig. 2, in the present embodiment, two sets of centering type brake insurance institutions are pacified along short transverse interval
Side loaded on riser guide, centering type brake insurance institution includes mounting base 1, brake eccentric 2 and hand log line 3, and brake is inclined
Heart wheel 2 is set in mounting base 1 with being able to rotate by installation axle 4, and is offered and rubbed on the part wheel face of the brake eccentric 2
Tooth 5 is wiped, cylinder boss 6 is provided on the lateral surface of brake eccentric 2, installation axle 4 is arranged across the cylinder boss 6, installation
The outer end of axis 4 is equipped with caging bolt 7, and the side of close riser guide is installed limited by fixing bundle band 8 on brake eccentric 2
Position block 9, fixing bundle band 8 is around cylinder boss 6 and its both ends is fixedly connected on the upper and lower end of limited block 9, opens up on limited block 9
There is the guide groove 10 along short transverse arrangement, 2 part of brake eccentric is located in the guide groove 10, cooperates the limited block 9
In being provided with spacer pin 11 in the mounting base 1, there are two the effects of limited block 9, and one is that cooperation spacer pin 11 is used for brake
The rotational angle of vehicle eccentric wheel 2 is limited, and another effect is can to play guiding role to the rotation of brake eccentric 2, is made
Entire mechanism kinematic is more reliable and more stable.
Two sets of centering type brake insurance institutions share a set of bar-link drive, and bar-link drive includes upper triggering connecting rod
12, lower triggering connecting rod 13 and rotating bar 14, the upper end of upper triggering connecting rod 12 are articulated with a set of centering type brake being located above and protect
On the brake eccentric 2 of dangerous mechanism, the lower end of lower triggering connecting rod 13 is articulated with underlying a set of centering type brake safety
On the brake eccentric 2 of structure, the bottom end of upper triggering connecting rod 12, the top of lower triggering connecting rod 13 and one end of rotating bar 14 are coaxially cut with scissors
It connects, the middle part of rotating bar 14 is installed on rotary bar socket 16 by articulated shaft 15, and the other end is articulated on hand log line 3.
If go up and down the fracture of traction power wirerope (or polyamide fibre band or chain etc.) accident, speed detector can be detected
Decrease speed to hand log line is greater than the set value, and then carries out emergency braking to hand log line, and hand log line drives rotating bar 14 around hinge
Spindle 15 rotates, so that the other end is driven to rotate, and the rotation of the other end will drive triggering connecting rod 12 and lower triggering connecting rod 13
It rotates simultaneously, the final rotation of brake eccentric 2 for driving two sets of centering type brake insurance institutions leads the contact lifting of its friction teeth 5
Rail brakes.
