Abstract
The utility model discloses a tensioning device of a high-temperature chain-drawing machine, comprising a stand, wherein a slide way is disposed in the stand; a tail bearing seat is slidably installed in the slide way; a fixed ring is disposed on the tail bearing seat; a steel wire rope is fixedly installed on the fixed ring; the steel wire rope is clamped on the fixed ring via a steel wire rope clamp; and a counter weight box is connected to the tail end of the steel wire rope. The tensioning device of a high-temperature chain-drawing machine disclosed by the utility model synchronously adjusts the tightness of a chain and ensures the chain to be always in a tensioned state, thereby solving the problems of chain separation and serious wear of chain.
Description
Technical field
The utility model relates to the chain type load transfer device, especially relates to the tensioning of chain-linked conveyer afterbody.
Background technology
In recent years, along with the raising of environmental consciousness and the utilization again of the energy, each cement production enterprise adopts AQC boiler and the generating of SP boiler preheating more.In the technological process of cogeneration, adopt high temperature resistant slide fastener conveyor apparatus.Because the temperature of convey materials is generally at 250～450 ℃, sometimes even reach 600 ℃, cause the machine for zipper chain frequently to expand with heat and contract with cold.Precursor rod-type tightening device can not be adjusted timely, thereby causes taking off chain, the chain severe wear, even draw bad casing, finally cause equipment normally not move.
The utility model content
The utility model provides a kind of tightening device, when chain expands with heat and contract with cold, adjusts the degree of tightness of chain synchronously, guarantees that chain is in slack-free state all the time, solves the problem of taking off chain and chain severe wear.
The utility model technical solution problem provides following scheme:
A kind of tightening device of high temperature machine for zipper; Comprise support, it is characterized in that: be provided with slideway in the said support, be slidingly fitted with the tail bearing seat in the said slideway; Said tail bearing seat is provided with set collar; Be installed with steel rope on the said set collar, said steel rope is clipped on the set collar through wire rope grip, and the end of said steel rope is connected with weight box.
The afterbody of said support is provided with the fixed pulley group, and said steel rope is pressed on the fixed pulley group.
The technical scheme of the utility model is: adopt gravity takeup.Counterweighted take-up is made up of anchor fitting, haulage cable, wire rope grip, fixed pulley, support, the weight box of being furnished with weight; Its principle does; On the firm bearing seat that is fixed on the machine for zipper afterbody of one end of hauling rope, walk around the fixed pulley other end and be fixed on the weight box.The weight scene of weight box is looked the length of machine for zipper and is confirmed.
Principle of work: chain is in the process of expanding with heat and contract with cold, and the length of chain changes, and weight box passes to the constant power of chain one through tail wheel, makes the chain in tension.Avoid taking off the generation of chain phenomenon.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to accompanying drawing, a kind of tightening device of high temperature machine for zipper comprises support 1; Be provided with slideway 2 in the said support 1, be slidingly fitted with tail bearing seat 3 in the said slideway 2, said tail bearing seat 3 is provided with set collar 4; Be installed with steel rope 5 on the said set collar 4, said steel rope 5 is clipped on the set collar 4 through wire rope grip 6, and the end of said steel rope 5 is connected with weight box 7; The afterbody of said support 1 is provided with fixed pulley group 8, and said steel rope 5 is pressed on the fixed pulley group 8.
Claims (2)
1. the tightening device of a high temperature machine for zipper; Comprise support, it is characterized in that: be provided with slideway in the said support, be slidingly fitted with the tail bearing seat in the said slideway; Said tail bearing seat is provided with set collar; Be installed with steel rope on the said set collar, said steel rope is clipped on the set collar through wire rope grip, and the end of said steel rope is connected with weight box.
