Description
Technical field
The utility model relates to the improvement of belt conveyor with carrying roller, and a kind of specifically antistatic polyvinyl chloride carrying roller is applicable under the coal mine and uses on the belt conveyor.
Background technology
Main by belt conveyor conveying coal under coal mine, carrying roller then is the critical piece of belt conveyor, this carrying roller generally is located at the centre and the both sides of belt bottom, and the trustship of both sides all slopes inwardly, and the quality of carrying roller quality is directly connected to the operation conditions and the running quality of ribbon conveyer.Because it is general relatively moister in the coal mine roadway, and dust is bigger, traditional steel carrying roller is perishable, also easily adsorb the frictional force that dust has strengthened carrying roller and conveyer belt, make shorten the application life of carrying roller, so usually use the steel carrying roller under the coal mine because of weight is big, Yi Shengxiu, water resistance difference are eliminated gradually; Owing under the coal mine methane gas is often arranged, exist unsafe factor, so belt conveyor carrying roller under the national requirements coal mine, must possess anti-fire-retardant, antistatic property.
Existing antistatic polyvinyl chloride carrying roller is compared with the steel carrying roller, have in light weight, noise is low, abrasion performance, but the sealing ring at these class carrying roller two ends is the seal ring assembly of maze-type structure, and seal ring assembly exterior protection structure is identical with the steel carrying roller, and this just causes its poor sealing performance, anti-trickle, coal slime poor effect, in running, impurity enters sealing ring and bearing inside easily, and finally wear and tear sealing ring and bearing, shorten application life, improved the running cost of enterprise.
Summary of the invention
That the purpose of this utility model is is simple in structure, easy to use, in light weight, noise is low, sealing performance is high, can prevent effectively that impurity such as sealing and coal slime enter sealing ring and bearing inside, the antistatic polyvinyl chloride carrying roller that increases the service life.
In order to reach above purpose; the technical scheme that the utility model adopted is: the antistatic polyvinyl chloride carrying roller; comprise roller carrier shaft; bearing; bearing support; carrying roller cylinder; interior labyrinth seal assembly; inner shield ring and outer back-up ring; on the two ends of roller carrier shaft are fixing respectively inner shield ring and outside back-up ring; inner shield ring and outside be fixed with bearing on the roller carrier shaft between the back-up ring; sheathed fixedly top chock on bearing; on the roller carrier shaft in the outside of bearing, be provided with interior labyrinth seal assembly; at the fixing sheathed upper supporting roller cylindrical shell in the outside of two bearing supports; it is characterized in that: the outer end of each bearing support is provided with the conical cavity of indent; over cap outside being fixed with on the roller carrier shaft in the conical cavity of bearing support is fixed with protective sleeve on the inwall of the bearing support between over cap and the interior labyrinth seal assembly outside.
The utility model is also implemented by following measure: described protective sleeve adopts long bottleneck structure, is made by nylon material, and the collar extension diameter is less than the internal orifice diameter, the inner outer wall of protective sleeve and the intracavity sidewall close-coupled of bearing support, and be coated with fluid sealant.
Described outer over cap adopts beveled structure, is made by nylon material, in the groove of the external port of protective sleeve inboard of over cap outside inserting.
Described bearing support is made by pvc material; Described carrying roller cylinder adopts ultra high molecular weight pvc to make, and carrying roller cylinder and bearing support are one by the gluing of PVC glue.
Labyrinth seal assembly in described; constitute by rotary seal circle and fixed seal ring; fixed seal ring and rotary seal circle be to being buckled together, and fixed seal ring is sheathed and be fixed on the roller carrier shaft, and the cavity wall of the lateral wall of rotary seal circle and the medial extremity of protective sleeve is tightly connected.
The beneficial effects of the utility model are: simple in structure, easy to use, in light weight, noise is low, sealing performance is high, prevented that effectively impurity such as water and coal slime from entering sealing ring and bearing inside, prolong application life, reduced running cost, improved the on-road efficiency of enterprise.
