Description
Technical field
The present invention relates to the appurtenances on a kind of safety protection equipment of hanging object hole, specifically a kind of automatic safety
The traction rollers device with elastic buffer that type cover plate is used, belongs to mechanical equipment technical field.
Background technology
It is required for being equipped with safety protection equipment on equipment lifting hole or maintenance hole in tier building, for example：Water
Power station, thermal power plant, steel plant and some enterprises, such lifting eye, manhole generally cover hole or hole using steel deck-plate
Hole surrounding installs permanent barrier, when the equipment or repair apparatus of lower floor in needing lifting building, it is necessary to hang out steel deck-plate, sets
Temporary fence, by lifting appliances such as crane or hoist engines during work；Workload is big, need many people to assist；Can be ornamental poor, with
Integrated environment is uncoordinated, unsightly；There is potential safety hazard.In today of automatic control technology high speed development, whole power station, fire
Power plant starts to realize the operation of unattended or few man on duty, if still using conventional hanging object hole safety protection equipment, just
Appointing so needs to be equipped with a large amount of staff, and this has not met the growth requirement of modern enterprise.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of Full automatic safety cover plate is used
The traction rollers device with elastic buffer, its simple structure with elastic buffer function, can avoid rigid impact, use
Safe and reliable, work noise is low.
According to the technical scheme that the present invention is provided：Traction rollers device with elastic buffer, it is characterised in that：Including traction
Roller shaft, roller bearing housing, roller shaft connecting plate, roller, drag link sleeve and pull bar；The traction rollers axle two ends pass through respectively
Roller bearing housing is supported, and the roller bearing housing at two ends is respectively and fixedly installed on two pieces roller shaft connecting plate, and roller passes through
Bearing supporting is arranged on traction rollers axle, and the drag link sleeve is sleeved on traction rollers shaft end and can freely rotate, pull bar
Set is located at roller outside, and the pull bar is arranged on drag link sleeve, and tie rod end is used to connect drawing chain.
As a further improvement on the present invention, the part at the outer end of drag link sleeve endoporus is left a blank, in leaving a blank for drag link sleeve
Section is provided with the tie rod hole for extending radially through drag link sleeve, and the pull bar is installed in tie rod hole, and pull bar two ends are located at outside drag link sleeve
Part is respectively installed with buffer spring, and described buffer spring one end covers lateral surface, buffer spring one by spring housing cylinder lever connecting rod
End passes through spring housing cylinder lever connecting rod end.
As a further improvement on the present invention, it is provided with copper sheathing between the drag link sleeve and traction rollers axle.
The present invention compared with prior art, has the following advantages that：Simple structure of the present invention, with elastic buffer function, energy
Rigid impact is enough avoided, safe and reliable, work noise is low.

Bar.
As shown in figure 1, in the embodiment of the present invention, the part at the outer end of the endoporus of the drag link sleeve 5 is left a blank, in drag link sleeve 5
Section of leaving a blank is provided with the tie rod hole for extending radially through drag link sleeve 5, and the pull bar 6 is installed in tie rod hole, and the two ends of pull bar 6 are located at pull bar
Part outside set 5 is respectively installed with buffer spring 7, and the one end of the buffer spring 7 covers 5 lateral surfaces by the cylinder lever connecting rod of spring housing 8,
The one end of buffer spring 7 passes through the end of 8 cylinder lever connecting rod of spring housing 6.
When specific installation is applied, the traction rollers axle 1 in traction rollers device of the present invention is arranged on door-plate, 4, roller
Support is in orbit, and pull bar 6 is connected on drawing chain, and door-plate motion, the buffering on pull bar 6 are driven during drawing chain positive and negative rotation
Spring 7 plays cushioning effect.
