[detailed description of the invention]
Can explain the present invention in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
By reference to the accompanying drawings 1 ~ 3, described scrapper conveyor chain tension adjusting device comprises right baffle-plate 1, right baffle plate 2, clamp 4, rotating shaft 5, advancing jack 8 and resistance chain device 10; Described right baffle-plate 1 and right baffle plate 2 are corresponding to be respectively fixed on the both sides backing plate 12 of scrapper conveyor 11 head, one end end face of right baffle-plate 1 and the corresponding flight chain 13 of right baffle plate 2 is equipped with an open slot 3, and correspondence is placed with the clamp 4 of a level in these two open slots 3, namely the clamp 4 of level can overall movement suitable in the open slot 3 being fixed on the left baffle on scrapper conveyor 11; As required, by bearing pin, left baffle can be provided with the corresponding relevant position being fixed on scrapper conveyor 11 both sides backing plate 12, side of open slot 3, by bolt, the opposite side of left baffle correspondence be fixed on the relevant position of scrapper conveyor 11 both sides backing plate 12 simultaneously;
The described right baffle-plate 1 correspondence position be positioned at outside open slot 3 is with it provided with the long through-hole 6 for vertically placing rotating shaft 5, the corresponding side corresponding to clamp 4, top of this rotating shaft 5 is fixedly connected with, the bottom of rotating shaft 5 is provided with packing ring and bayonet lock, namely rotating shaft 5 can only move around along long through-hole 6, and can not come off by long through-hole 6, the action of rotating shaft 5 pairs of clamps 4 so not only can be utilized to carry out spacing, but also ensure that clamp 4 with rotating shaft 5 for the center of circle is rotated, thus can reach the object of being convenient to place or take out clamp 4 in open slot 3; As required, described rotating shaft 5 can be set to one inverted " L " oblique crank Z, the horizontal side correspondence of this axle is fixedly connected with to the corresponding side of clamp 4, and the vertical side correspondence of this axle runs through long through-hole 6, and bayonet lock is installed through after long through-hole 6 in the termination of this vertical side;
An advancing jack 8 is connected by bearing pin 7 in the middle part of described clamp 4, can correspondingly with scraper plate conflict in piston rod 9 termination of this advancing jack 8, namely the piston rod 9 of advancing jack 8 correspondence can push scraper plate action when stretching out, thus reach the object of chain 13 tensioning by connecting multiple scraper plate, simultaneously, a mobile is constituted, therefore, it is possible to the impact that utilize the clamp 4 with free gap swing that actv. avoids advancing jack 8 to produce when action causes scrapper conveyor 11 because clamp 4 is corresponding with advancing jack 8; For ease of installation or removal, can arrange in the bottom of clamp 4 and be used for the otic placode that connect corresponding to advancing jack 8; For ease of operation advancing jack 8, by hydralic hose pipeline, advancing jack 8 can be connected with corresponding hydraulic chock running valve, thus when the piston rod 9 utilizing highly pressurised liquid to control advancing jack 8 stretches out, can synchronously promote scraper plate and move;
As required, can the one-way lock possessing locking function be set in the hydraulic tubing of telescopic jack 8, namely the piston rod 9 of telescopic jack 8 is after the corresponding scraper plate of promotion, the hydraulic tubing of telescopic jack 8 can be locked by one-way lock, thus actv. avoid advancing jack 8 because of be subject to chain 13 antagonistic force and occur retraction; In addition, described device is also at least provided with a pair resistance chain device 10, this a pair resistance chain device 10 is in the position being slightly distal to advancing jack 8 piston rod 9 extreme length, independently be arranged in the transient channel of scraper circular hole of flight chain 13 both sides, namely the scraper plate of chain 13 one end of tensioning is needed to be located under the stop of resistance chain device 10, the scraper plate of chain 13 other end moves to by the scraper plate direction of locating under the promotion of advancing jack 8 piston rod 9, and finally reaches the object of chain 13 tensioning.
When implementing scrapper conveyor chain tension adjusting device described in the utility model, first resistance chain device 10 is fixed in scrapper conveyor 11 transitional slot circular hole, then left baffle is separately fixed on the backing plate 12 of scrapper conveyor 11 head both sides, again clamp 4 level is put into the open slot 3 of left baffle, and keep rotating shaft 5 can move in the long through-hole 6 of right baffle-plate; Now, link together corresponding with clamp 4 for advancing jack 8, one end of hydralic hose is connected the joint on advancing jack 8 cylinder body, the other end of hydralic hose is connected on hydraulic chock running valve, then just can control the piston rod 9 of advancing jack 8 and stretch out by controlling maneuvering valve, and promote corresponding scraper plate and move; When after the tensioning of whole scratch board machine chain 13, loose round-link chain on chain 13 between the scraper plate of being located by resistance chain device 10 and the scraper plate promoted by piston rod 9 is sliced off, then chain 13 two ends correspondence is coupled together with chain ring the tensioning operation just completed scratch board machine chain; After the tensioning end of job, advancing jack 8 can be dismantled, clamp 4 is overturn out open slot 3 and is placed in by the motor of scrapper conveyor 11 by recycling rotating shaft 5, thus reaches and do not affect the object that scrapper conveyor normally transports coal.
The non-detailed portion of the utility model is prior art, therefore the utility model is not described in detail.
