Abstract
The utility model relates to maintaining equipment for coal mining use, specifically to a scraper conveyor tight chain device. The utility model solves the problems that a manual operation for connecting chains and uninstalling chains in daily maintenance of the scraper conveyor has safety hidden trouble and lower efficiency etc. The scraper conveyor tight chain device comprises a reaction jack, a portable hand pump connected with the reaction jack and connecting devices respectively connected with the upper and lower ends of the reaction jack. The utility model significantly reduces the waste of time for uninstalling the chains and saves much time for other equipments to have maintenance. Specifically speaking, if one-time chain uninstallation saves 15 minutes, then approximately 45 minutes can be saved everyday. Therefore, the utility model reduces the maintaining time and lowers the labor intensity for workers.
Description
Technical field
The utility model relates to a kind of colliery repair apparatus, is specially a kind of slat conveyer chain tensioner sheet.
Background technology
The 40T slat conveyer is as the main load transfer device in down-hole; the situation that when down-hole daily attention, maintenance and installation, runs into chain link and tear chain open through regular meeting; but the 40T slat conveyer self does not have chain tension adjusting device; recognize that through long field observation and workman's informal discussion the measure of site disposal fault generally is two workman's coordinating operations; people's master cock button while, a people started the moment chain link at the 40T slat conveyer; though also can finish the work, this operational means really can have been brought certain working strength and potential safety hazard to the field worker operation.
Summary of the invention
The utility model exists manual operations to bring problems such as potential safety hazard and inefficiency in order to solve daily attention slat conveyer chain link and to tear open in the chain, and a kind of slat conveyer chain tensioner sheet is provided.
The utility model is realized that by following technical scheme a kind of slat conveyer chain tensioner sheet comprises the counteraction jack, and the counteraction jack is connected with the portable hand press pump, and the counteraction jack is connected with connecting device respectively in two ends up and down.
Described connecting device is the gusseted seat, and one of them triangle supporting base is connected with the U-link that band is sold by the tensioning chain, and another triangle supporting base is connected with chain link quick coupling by the tensioning chain.
The principle of work of slat conveyer chain tensioner sheet described in the utility model is to utilize the portable hand press pump to provide the pressure of 30MPA to drive the counteraction hydraulic jack, to be connected the paddled conveyor chain tensioner at the utility model two ends in advance, reached the purpose of dismounting chain.
The utility model compared with prior art: 1, adopt the counteraction jack, increased active length, make equipment more flexible.2, the design of utilization tensioner chain can improve the field of application of equipment greatly.3, the design of slat conveyer chain tensioner sheet has taken into full account the actual conditions of down-hole, and assurance equipment is light, easy to carry as far as possible.4, easy maintenance, operation is reliable.
Compare with existing manual experiential operating, be reduced to people's operation by two former people's coordinating operations, the use of having saved labour power, and improved the safety of working greatly.And greatly reduce the time because of needing the dismounting chain to waste, for a large amount of time has been saved in the maintenance of other equipment, can save 15 minutes by chain of every dismounting, save about 45 minutes average every day, reduced the repair time, reduces labor strength.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1-pin, 2-U shape coupling link, 3-tensioning chain, 4-triangle supporting base, 5-counteraction jack, 6-gusseted seat, 7-tensioning chain, the quick coupling of 8-chain link, 9-portable hand press pump.
The specific embodiment
As schematically shown in Figure 1, a kind of slat conveyer chain tensioner sheet comprises counteraction jack 5, and counteraction jack 5 is connected with portable hand press pump 9, and the counteraction jack is connected with connecting device respectively in two ends about in the of 5.Described connecting device is a gusseted seat 4,6, and one of them triangle supporting base 4 is connected with band by tensioning chain 3 and sells 1 U-link 2, and another triangle supporting base 6 is connected with chain link quick coupling 8 by tensioning chain 7.
Algorithm: 1, earlier with the control position of getting to of 40T slat conveyer chain tensioner sheet, counteraction jack 5 strokes are 500mm.
2, the chain link quick coupling 8 of 40T slat conveyer chain tensioner sheet is connected to scraper plate and connects, and fix.In detail operation is earlier the fixed head of quick coupling to be filled in during scraper plate encircles repeatedly, it is done 90 ° then and horizontally rotates, and fixes the back and drags connection chain with hand and determine that it is reliable.
3,40T slat conveyer chain tensioner sheet U type coupling link is connected to scraper plate and connects, and fix with pin 2.Operation is earlier the pin of U type ring to be opened in detail, finds the suitable chain of rings and connects reliable with pin 2.
4,40T slat conveyer chain tensioner sheet is fixed after, use portable hand press pump 9 to begin to suppress, can play protection counteraction jack by automatically unloading when pressure reaches 30MPA portable hand press pump.
