Right brake (16a) is by connecting rod (1a), the right side on the left of right brake cylinder (14a), braking stage clip (15a), right brake Connecting rod (5a), right brake left hand brake disk (2a), right brake right side brake disk (4a), right brake frame on the right side of brake (6a) form;Right brake (16a) is that cunning is contained in I-steel guide rail (3);One end of braking stage clip (15a) withstands on right braking On the cylinder body of oil cylinder (14a), the other end of braking stage clip (15a) withstands on the piston rod of right brake cylinder (14a);Right brake oil On the left of the cylinder body of cylinder (14a) and right brake, connecting rod (1a) is hinged, on the right side of the piston rod of right brake cylinder (14a) and right brake Connecting rod (5a) is hinged;On the right side of connecting rod (1a) on the left of right brake, right brake connecting rod (5a) respectively with right brake frame (6a) Hinged;On the left of right brake, connecting rod (1a) is hinged with right brake left hand brake disk (2a), on the right side of right brake connecting rod (5a) with Right brake right side brake disk (4a) is hinged;Right brake left hand brake disk (2a), right brake right side brake disk (4a) are along the right side The slideway of brake frame (6a), does the motion perpendicular to I-steel guide rail (3) web direction.
Passage oil cylinder (7) is located between left brake (16), right brake (16a), the cylinder body of passage oil cylinder (7) and left system Dynamic device frame (6) is hinged, and the piston rod of passage oil cylinder (7) is hinged with right brake frame (6a);Left brake frame (6), the right side Brake frame (6a) cunning is contained in I-steel guide rail (3), can move along the length direction of I-steel guide rail (3).
So that mining monorail crane cable consignment system complete set of equipments moves right as a example it is illustrated below.
In the stage of shutdown, passage oil cylinder (7) is to maintain piston rod retracted state, left brake cylinder (14), right brake cylinder (14a) be at the on-position stretched out, 3-position 4-way hand-operated direction valve (10), 3-position 4-way hand-operated direction valve (10a), three Four-way hand-operated direction valve (10b), 3-position 4-way hand-operated direction valve (10c) are at middle position state.
The first step: when walking mechanism prepares to move right, 3-position 4-way hand-operated direction valve (10a) is pulled left position, makes The p mouth of 3-position 4-way hand-operated direction valve (10a) is connected with a mouth, and b mouth is connected with t mouth, and high-pressure emulsion passes through high-pressure emulsification Liquid interface (12), the a1 mouth of relief valve (13), the p mouth of 3-position 4-way hand-operated direction valve (10a) and a mouth and hydraulic lock (8), sequentially The p mouth of valve (9a), the p mouth of sequence valve (9b) are connected, because the pressure at sequence valve (9a), (9b) k mouth is not reaching to them Set pressure, so sequence valve (9a), (9b) are not opened, so, high-pressure emulsion is by a1, a2 of hydraulic lock (8) Mouth is connected with the a0 mouth of left brake cylinder (14), and the piston rod making left brake cylinder (14) is in hydraulic coupling and braking stage clip (15) Elastic force collective effect under stretch out, drive connecting rod (1) on the left of left brake, connecting rod (5) rotates on the right side of left brake, makes left braking Device left hand brake disk (2), left brake right side brake disk (4) are moved to the direction of compression I-steel guide rail (3) web, and finally Make left brake left hand brake disk (2), left brake right side brake disk (4) compress the web of I-steel guide rail (3), make left braking Device (16) is in on-position;When left brake left hand brake disk (2), left brake right side brake disk (4) compression I-steel are led After the web of rail (3), the pressure rise of the a0 mouth of left brake cylinder (14), after reaching the set pressure of sequence valve (9a) k mouth, Sequence valve (9a) is opened, and so that the p mouth of sequence valve (9a) is connected with p1 mouth, and high-pressure emulsion passes through p, p1 of sequence valve (9a) Mouth is connected with the b0 mouth of right brake cylinder (14a) with b1, b2 mouth of hydraulic lock (8a), makes the piston of right brake cylinder (14a) Rod cavity feed liquor, plunger shaft returns liquid, makes the piston rod of right brake cylinder (14a) overcome the elastic force of braking stage clip (15a) to retract, band Move connecting rod (1a) on the left of right brake, connecting rod (5a) rotates on the right side of right brake, makes right brake left hand brake disk (2a), right system Dynamic device right side brake disk (4a) is moved to the direction deviating from I-steel guide rail (3) web, and finally makes right brake left hand brake Disk (2a), right brake right side brake disk (4a) are separated with the web of I-steel guide rail (3), make right brake (16a) be in pine Lock state;Then just 3-position 4-way hand-operated direction valve (10a) turns back middle position.
