Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model relates to a chain tightening device of scraper conveyor's structure, as shown in fig. 1, including flexible hydro-cylinder 1, 1 inside telescopic link 2 that sets up of flexible hydro-cylinder, 2 tip of telescopic link set up connecting hole 4, connect two anchor chains 7 on the connecting hole 4, and flexible hydro-cylinder 1 is kept away from 2 one end of telescopic link and is set up connecting portion, sets up the through-hole on the connecting portion, and the through-hole passes through 3 connection go-between 5 of bolt, and two anchor chains 7 are connected to go-between 5, and 7 end connection couples 6 of anchor chain, and flexible hydro-cylinder 1 is connected through hydraulic pressure oil pipe 9 and is expanded the puller 8. The telescopic rod 2 adjusts the length of the telescopic oil cylinder 1, and then adjusts the distance between the connecting ring 5 and the connecting part to adapt to scraper conveyors with different widths.
A lock catch is hinged at the opening of the hook 6, one end of the lock catch is hinged and can rotate around the hook 6, a spring is fixed between the hook 6 and the lock catch, and the spring pulls the lock catch to lock the hook 6 closed; when the spring is compressed, the lock catch is in an open state.
The hydraulic oil pipe 9 is provided with a one-way lock.
The connecting part, the bolt 3 and the connecting ring 5 are all made of stainless steel materials.
The anchor chain 7 is formed by welding high-strength alloy materials in a closed mode.
The embodiment is used in the maintenance of 10201 withdrawal passageway, 10201 return air lane, 10202 auxiliary transport lane scraper conveyor of construction, has alleviateed worker's intensity of labour for the tight chain repair time of scraper blade, has promoted workman's safety in operation, has guaranteed equipment safety and maintenance efficiency. The facility has strong practicability, effectively avoids the accident of hurting people due to unhooking when the tensioning chain is tensioned, shortens the maintenance time, and plays a positive role in ensuring the safety of equipment and promoting the production efficiency.
The utility model relates to a tight chain device of scraper conveyor's theory of operation: by utilizing the characteristic that the telescopic oil cylinder 1 is compressed and stretched, and through combining the tension device 8, the anchor chain 7 and the hook 6, when the tension device 8 is pressed, the telescopic oil cylinder 1 is contracted to drive the target that the anchor chain 7 moves, the traditional chain block is replaced, the chain is tensioned when the scraper is overhauled, the labor intensity of workers is reduced, and the overhauling efficiency is improved.
The utility model relates to a scraper conveyor tight chain device's working process: the tensioning device 8 controls the hydraulic oil cylinder to stretch out and draw back, the hydraulic oil cylinder stretches out, the hooks 6 at the two ends are respectively connected to the scraper chain of the scraper conveyor, and the lock catch structure of the hook 6 is locked and fixed with the hanging part of the scraper chain; the hydraulic oil cylinder shrinks, and the scraper chain shrinks to perform chain tightening operation by driving the hook 6, so that the scraper chain reaches a required working tensioning state; thereby alleviateed worker's intensity of labour for the tight chain maintenance time of scraper blade, promoted workman's work safety nature, guaranteed equipment safety and maintenance efficiency.
The chain tightening device of the scraper conveyor has simple and reasonable structure, rapid and convenient installation and operation, safety and reliability, lightens the labor intensity of workers, and is formed by assembling and welding a telescopic oil cylinder, a tensioning device, an anchor chain and a hydraulic oil pipe; the maintenance time of the scraper chain tightening is shortened, the operation safety of workers is improved, and the equipment safety and the maintenance efficiency are ensured; the durability is strong, the damage is not easy, and the material cost is saved.
