Heavy power and free overhead conveyer
Technical field
The present invention relates to the equipment in a kind of automation convey materials system, particularly a kind of heavy power and free overhead conveyer.
Background technology
The bearing track of existing power and free overhead conveyer adopts the double flute steel, the wheel of car group is walked in the cavity of a relative closure, channel-section steel edge of a wing inner plane is wherein walked wheel tread for the car group, the limit, the edge of a wing of channel-section steel is the spigot surface of car group, the power and free overhead conveyer of this bearing track structure exists load-carrying capacity low, noise is big, and the shortcoming of installation and maintenance inconvenience is not suitable for carrying heavy convey materials.
Summary of the invention
Heavy power and free overhead conveyer provided by the invention has solved that existing power and free overhead conveyer load-carrying capacity is low, and noise is big, the inconvenient and technical matters that is not suitable for carrying heavy convey materials of installation and maintenance.
The present invention overcomes the above problems by following scheme:
Heavy power and free overhead conveyer, comprise actuating device 1, conduction chain 6, tightening device 7, rail system 2, preceding dolly 3, back dolly 4 and load beam 5, described rail system 2 is by traction rail 9, the first carrying rail 19, the second carrying rail 20 and draw together to the C of under shed font is configured to, the inner top surface that frame drawn together in the upper flange 10 and the C font of double-tee traction rail 9 is fixed and welded together, double-tee first carrying rail 19 and the double-tee second carrying rail 20 parallel being set up in parallel at opening part from frame to the C of under shed font that draw together, first the carrying rail 19 right web and on, the right open end that frame drawn together in the Right Inboard of lower wing plate and C font fixedly is welded together, second the carrying rail 20 left web and on, the left open end that frame drawn together in the inboard, a left side and the C font of lower wing plate fixedly is welded together, be movably set with car body 18 between the first carrying rail 19 and the second carrying rail 20, the a pair of car group travelling wheel 16 of car body 18 be movably arranged on first the carrying rail 19 web directly over upper flange and second the carrying rail 20 web directly over upper flange on, the bearing that is provided with in a pair of car group travelling wheel 16 of car body 18 is a duplex bearing 17, the a pair of track adjusting wheel that chain supports dolly 12 be movably arranged on traction rail 9 by traction rail upper flange 10, in the channel suspending rail that traction rail lower wing plate 11 and traction rail web are formed, the lower end that chain supports dolly 12 by chain cut somebody's hair 14 with car group lifting pawl 15 gear motions of the upper end of car body 18, chain support dolly 12 about half car link together with described conduction chain 6 by bindiny mechanism 13.
Described conduction chain 6 is the die forging knockdown chain.
The present invention has the load-carrying capacity height, and simple in structure, compact, stable action is reliable, is convenient to make, and cost is low, and is easy to install, is particularly suitable for the conveying to heavy material.

The specific embodiment
Heavy power and free overhead conveyer, comprise actuating device 1, conduction chain 6, tightening device 7, rail system 2, preceding dolly 3, back dolly 4 and load beam 5, described rail system 2 is by traction rail 9, the first carrying rail 19, the second carrying rail 20 and draw together to the C of under shed font is configured to, the inner top surface that frame drawn together in the upper flange 10 and the C font of double-tee traction rail 9 is fixed and welded together, double-tee first carrying rail 19 and the double-tee second carrying rail 20 parallel being set up in parallel at opening part from frame to the C of under shed font that draw together, first the carrying rail 19 right web and on, the right open end that frame drawn together in the Right Inboard of lower wing plate and C font fixedly is welded together, second the carrying rail 20 left web and on, the left open end that frame drawn together in the inboard, a left side and the C font of lower wing plate fixedly is welded together, be movably set with car body 18 between the first carrying rail 19 and the second carrying rail 20, the a pair of car group travelling wheel 16 of car body 18 be movably arranged on first the carrying rail 19 web directly over upper flange and second the carrying rail 20 web directly over upper flange on, the bearing that is provided with in a pair of car group travelling wheel 16 of car body 18 is a duplex bearing 17, the a pair of track adjusting wheel that chain supports dolly 12 be movably arranged on traction rail 9 by traction rail upper flange 10, in the channel suspending rail that traction rail lower wing plate 11 and traction rail web are formed, the lower end that chain supports dolly 12 by chain cut somebody's hair 14 with car group lifting pawl 15 gear motions of the upper end of car body 18, chain support dolly 12 about half car link together with described conduction chain 6 by bindiny mechanism 13.
When delivery system was in running state, the loading dolly moved under the traction of conduction chain 6.When long-pending putting, because preceding dolly 3 is stopped device and blocks, the lifting pawl is depressed, the engagement that makes the loading dolly break away from root conduction chain 6 stops, and when a dolly of back arrived, the tailgate of the preceding shovel loading dolly along the front on its preceding dolly lifted, and by leverage, force the lifting pawl of second loading dolly to fall, second dolly also stopped thereupon, thereby reach long-pending playing function.
