Abstract

The utility model provides a fill is carried chain strip and can be dismantled driving cog, belongs to driving cog technical field. The utility model aims to design an it carries the fill is carried chain strip and can be dismantled driving cog that the change structure was easily dismantled to formula chain drive tooth to be exclusively used in the dry -type slag extractor of thermal power factory fill. The utility model discloses a fluted disc is installed on the main shaft, and the fluted disc comprises coaxial high dish and chassis, and high dish and chassis form a dish groove, and open at the driving cog middle part has the recess that matees with high dish, and insert in the driving cog centre bore on the chassis, and the fluted disc fastening pore pair on the driving cog fastening kong yugao dish on the driving cog should. The utility model discloses can independently dismantle, easy operation, convenient and practical designs into detachable construction with the driving cog, has not only reduced the maintenance degree of difficulty, moreover the very big repair time that has saved. Need not during the change to pull down the whole axle and the teeth of a cogwheel, only need can change under perpendicular between teeth of a cogwheel barring to the chain that needs to be changed.

Description

The detachable driving cog of bucket elevator chain

Technical field

This utility model belongs to driving cog technical field.

Background technology

Thermal power plant uses dry-type slag extractor system, not only water saving, environmental protection, also can be using the slag after burning as the raw material of the industry such as construction material, manufacture of cement.But the bucket elevator chain drive tooth of dry-type slag extractor system is easy to wear, need every year to change.Due to long-play, must be replaced every year, existing driving cog needs many people to dismount when changing, and spare part processing charges often overlaps driving cog (including axle and the two width gear teeth) more than 1.2 ten thousand yuan.Replacing must employ slingcart by it from slag drying machine system bucket elevator top is transported, and disassembly process needs a large amount of manpowers and time, changes and once needs the time.

Summary of the invention

The purpose of this utility model is that a kind of thermal power plant dry-type slag extractor bucket type chain drive tooth that is exclusively used in of design is readily disassembled the detachable driving cog of bucket elevator chain changing structure.

Fluted disc of the present utility model is arranged on main shaft, fluted disc is to be made up of coaxial high dish and chassis, high dish and chassis form a dish groove, the groove mated with high dish is had in the middle part of driving cog, chassis is inserted in driving cog centre bore, and the driving cog fastener hole on driving cog is corresponding with the fluted disc fastener hole on high dish.

This utility model is independently detachable, simple to operate, convenient and practical, and driving cog is designed to demountable structure, not only reduces maintenance difficulty, and is greatly saved the repair time.Without whole axle and the gear teeth are pulled down during replacing, it is only necessary to, the most replaceable between the gear teeth jiggering that needs are changed to chain directly vertically below.

Detailed description of the invention

Fluted disc of the present utility model is arranged on main shaft 3, fluted disc is to be made up of coaxial high dish 2 and chassis 3, high dish 2 and chassis 3 form a dish groove 9, the groove 5 mated with high dish 2 is had in the middle part of driving cog 1, chassis 3 is inserted in driving cog 1 centre bore, and the driving cog fastener hole 6 on driving cog 1 is corresponding with the fluted disc fastener hole 8 on high dish 2.Driving cog 1 is divided into four, and four driving cogs 1 combine just to surround and closely cooperate with fluted disc.

Driving cog is transformed into the demountable structure being fixed by bolts on fluted disc by this utility model, and a circle is divided into the detachable gear teeth of pintongs, is fixed by bolts on toothholder.

Fluted disc is installed on this utility model main shaft, on each fluted disc on have four detachable driving tooths, be bolted.In driving chain, that detachable driving tooth serious wear needs to change, whole axle need not be taken off, as long as by need the detachable driving tooth changed rotate to underface not with the position of chain contact, so that it may be individually replaced the detachable driving tooth needing to change.

1. when changing, lifting appliance need not be used, it is only necessary to the gear teeth (gear teeth of the 1/4) jiggering that will dismantle to underface not with the position of bucket elevator chain contact, can dismantle.

2. saving a large amount of manpowers, shorten replacing construction, fewer workers utilizes to be replaced for several hours

3. because being detachable, removable parts tail off, and save processing charges

4. the gear teeth can use high-abrasive material to process, and was changed once from 1 year the replacement cycle, becomes 3 years changing once.

5. at present because replacing construction is long, so more the change jobs method of operation to be considered and unit load, shortening working hours after transformation, beneficially unit safety is stablized and property.

Claims

1. the detachable driving cog of bucket elevator chain, it is characterized in that: fluted disc is arranged on main shaft (3), fluted disc is to be made up of coaxial high dish (2) and chassis (3), high dish (2) and chassis (3) form a dish groove (9), driving cog (1) middle part has the groove (5) mated with high dish (2), chassis (3) is inserted in driving cog (1) centre bore, and the driving cog fastener hole (6) on driving cog (1) is corresponding with the fluted disc fastener hole (8) on high dish (2).
