The specific embodiment
As shown in the figure: ring-shaped guide rail 2 is formed by being positioned at top carrying rail 12 and being positioned at following traction rail 9, and the some dollies 3 that can walk are arranged on traction rail 9, on carrying rail 12 the some carrying chassis 17 that can walk is arranged; Between carrying chassis 17 and dolly 3, pushing mechanism is arranged, and move by pushing mechanism promotion carrying chassis 17 by dolly 3; Between two adjacent dollies 3, utilize contact bar 4 to interconnect; Mouth at driver train 1 is provided for the friction wheel 18 that driving trolley 3 is walked, and the friction member with friction wheel 18 couplings is set on dolly 3.
Contact bar 4 is clamped between friction wheel 18 and the friction track adjusting wheel 13, and friction wheel 18 rotates drive contact bar 4 and promotes dolly 3 walkings, and contact bar 4 at this moment just plays a part friction member.The transversal surface of traction rail 9 is horizontal H shape, and two road wheels 7 of dolly 3 lay respectively on the H shape traction rail 9, and the outer rim of each road wheel 7 contacts with the bottom 24 of H shape traction rail 9, and the track adjusting wheel 8 of dolly 3 contacts with the middle part 22 of H shape traction rail 9.Utilizing H shaped steel to make traction rail 9 is a kind of simple and efficient ways.
In pushing mechanism, push rod 5 is arranged at the bottom of carrying chassis 17, is provided with on dolly 3 and cuts somebody's hair 14, when dolly 3 promotes carrying chassis 17, cuts somebody's hair and 14 withstands push rod 5.The pushing mechanism here is a kind of simpler structure, can be as long as can when dolly 3 moves, drive the mechanism that moves of carrying chassis 17 as pushing mechanism, even can directly utilize the upper end of dolly 3 to promote carrying chassis 17.On ring-shaped guide rail 2 or the next door of ring-shaped guide rail 2 and friction wheel 18 relative positions friction track adjusting wheel 13 is set, friction member friction wheel 18 with rub between the track adjusting wheel 13.Usually friction wheel 18 and driver train 1 thereof and friction track adjusting wheel 13 all can be installed in the melt pit of the pre-buried frame in ring-shaped guide rail 2 next doors, can certainly be installed on the ring-shaped guide rail 2.
Below carrying chassis 17 pilot bar 20 is set, is provided with and traction rail 9 guide groove 26 in the same way on traction rail 9, pilot bar 20 is positioned at guide groove 26 with the lower end of push rod 5.Hinged reel cage 23 on frame, driver train 1 is installed on the reel cage 23, the other end at reel cage 23 connects spring 19, the other end of this spring 19 is connected with frame, spring 19 applies a power for friction wheel 18 by reel cage 23, make friction wheel 18 be adjacent to friction member all the time, friction force is passed to friction member, drive dolly 3 by friction member and move.
The carrying rail 12 can by two levels to parallel L type flanging support plate constitute, between two L type flanging support plates, form guide groove 26, the bottom of L type flanging support plate connects some vertically arranged support horses 11, the cross bar 25 of horizontal arrangement is set at per two 11 of relative support horses, cutting somebody's hair and utilizing the bearing pin 15 hinged lock dogs 16 that are used for spacing push rod 5 on 14 in that traction rail 9. is installed on the cross bar 25, this lock dog 16 can push rod 5 with cut somebody's hair 14 contact after with push rod 5 locking, in order to avoid push rod 5 displacements come off.
During installation, endless track 2 is fixed on a certain fixed area in operation place by the steel structure frame that adds according to the practical layout in arts demand and operation place, carrying rail 12 generally speaking is positioned on the ground, traction rail 9 is positioned at underground, being goes in ring arranges, carrying rail 12 utilizes frame to interconnect with traction rail 9, and friction driving mechanisms 1 is fixed on the reel cage 23 in the melt pit of building up in advance, and fixes on the friction track adjusting wheel 13 on its opposite.
During work, be placed on parts on the carrying chassis 17 of band movable push bar 5 and pilot bar 20 by technological requirement, driving the cut somebody's hair contact bar 4 that supports dolly 3 of mutually hinged band by friction wheel 18 does to go in ring on traction rail 9 and moves, promote the station of the carrying chassis 17 of band movable push bar 5 and pilot bar 20, satisfy assembling and delivery technology requirement to appointment.
Its friction driving mechanisms 1 places on the interior reel cage 23 of melt pit, the friction carrying capacity is regulated by spring 19, trailer wagon 3 is to go in ring on traction rail 9 to be arranged, numerous contact bars 4 are hinged with numerous dolly 3, the activity on the dolly 3 cut somebody's hair 14 with carry rail 12 on have a steering wheel carrying chassis 17 engage.When contact bar 4 contacts with friction wheel 18 and friction track adjusting wheel 13, friction wheel 18 is at driver train 1---motor reducer drive make down on the traction rail 9 dolly 3 operations, the 14 carrying chassis 17 that drive on the carrying rails 12 of cutting somebody's hair of the activity on the dolly 3 move along ring-shaped guide rail 2.Its load-carrying capacity is strong, operation beat height, and operating cost is low, and is easy to maintenance, and pollute and lack, low noise, the cost performance height of equipment is the belt delivery system of special type that can satisfy above requirement.
