Abstract
The invention relates to a scraper chain disassembling and assembling machine, which is characterized in that the invention takes a hydraulic oil cylinder (1) as a mainbody; a cylinder pipe (2) and a piston rod (3) of the hydraulic oil cylinder (1) are respectively provided with a left bracket (6) and a right bracket (7) through a left pin shaft (4) and a right pin shaft (5); the two ends of the left bracket (6) and the right bracket (7) are respectively provided with a chute (8) which is internally provided with a hook (9), and the hook is provided with an arc concave trough (10); the hook (9) can be stretched and contracted in the chute (8); the left bracket (6) and the right bracket (7) are respectively provided with an adjusting trough (11); the hook (9) is provided with a pulling rod (12) which passes through the adjusting trough (11); the hook (9) can be pulled to be stretched and contracted in the chute (8) along the adjusting trough (11) by the pulling rod (12). The invention has safe operation and high efficiency, the tightness of the chain can be exactly mastered and the chain is subject to uniform and balanced force in the disassembly and assembly process.
Description
Technical field
The present invention relates to mechanical equipment technical field, is a kind of equipment that is used for the connection and the dismounting of scraper conveyer chain specifically.
Background technology
At present, in various drag conveyors, lack special-purpose flight chain disassemblerassembler.Be that operating personnel are bundled in chain on the frame with iron wire during the dismounting chain, start the motor jack or advance that make the lax or tensioner of chain carry out the dismounting and the installation of chain, this flight chain dismounting means are dangerous big, and the wounded or disabled accident of workman takes place often; Frequent motor starting causes the motor damage; Starting current produces a large amount of energy consumptions; Chain and transmission mechanism influence service life even damage chain rupture because of the effect of being hit; Tight chain power is uncontrollable; The degree of tightness of two chains can not be consistent; Operating efficiency is low.
Summary of the invention
Deficiency at existing equipment, the invention provides a kind of can be rapidly, the scraper chain disassembling and installing machine of safety, easy disassembly chain, the present invention solves the technical scheme that its technical problem takes: the present invention is based on hydraulic jack, on the earthen pipe of hydraulic jack and piston rod, be connected a support by bearing pin respectively, the two ends of support respectively are provided with chute, be provided with hook in the chute, hook is provided with circular groove, and hook can stretch in chute.Support is provided with regulating tank, and pull bar is set on the hook, and it is flexible in chute that pull bar passes regulating tank pulling hook.When the hook at support two ends was in the outermost end of support respectively, two hooks were symmetrical with respect to bearing pin respectively.
The invention has the beneficial effects as follows: handling safety, the efficient height, the degree of tightness of chain can accurately be grasped, and chain is stressed uniform and stable in disassembly process.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the upward view of structural representation of the present invention.
Among the figure, 1, hydraulic jack, 2, earthen pipe, 3, piston rod, 4, left bearing pin, 5, right bearing pin, 6, left socle, 7, right support, 8, chute, 9, hook, 10, circular groove, 11, regulating tank, 12, pull bar.
The specific embodiment
With reference to accompanying drawing, the invention is characterized in based on hydraulic jack 1, be connected left socle 6 and right support 7 by left bearing pin 4 with right bearing pin 5 respectively on the earthen pipe 2 of hydraulic jack 1 and the piston rod 3, the two ends of left socle 6 and right support 7 respectively are provided with chute 8, be provided with hook 9 in the chute 8, hook 9 is provided with circular groove 10, hook 9 can stretch in chute 8, be respectively equipped with regulating tank 11 on left socle 6 and the right support 7, on the hook 9 pull bar 12 is set, pull bar 12 passes regulating tank 11 and links to each other with hook 9, and it is flexible in chute 8 that pull bar 12 can spur hook 9.When the hook 9 at left socle 6 and right support 7 two ends was in the outermost end of left socle 6 and right support 7 respectively, two hooks 9 were symmetrical with respect to left bearing pin 4 and right bearing pin 5 respectively.
Operation principle of the present invention and process are such: scraper chain disassembling and installing machine blocks flight chain by linking up with 9 circular groove 10, and chain is applied tightening force.Can stretch out and withdraw in the chute 8 of hook 9 on left socle 6 and right support 7, hook 9 tangles chain when reaching the top, carries out chain dismounting operation, and hook 9 is withdrawn after finishing the chain dismounting, so that take scraper chain disassembling and installing machine away from drag conveyor.The hook 9 tight chain power equal and opposite in directions that when the dismounting chain, two chains applied, and with the chain duty be subjected to force direction consistent, it makes a concerted effort just in time to have avoided hydraulic jack 1 to be subjected to additional bending moment by the center line of hydraulic jack 1.The size of tight chain power is controlled by the oil pressure of hydraulic jack 1, can grasp the degree of tightness of two chains exactly.The left socle 6 of scraper chain disassembling and installing machine links to each other with hydraulic jack 1 with right bearing pin 5 by left bearing pin 4 with right support 7, links up with the change of 9 positions in the time of can adapting to the diverse location of two chains hooks 9 and the operation of dismounting chain by rotation.Scraper chain disassembling and installing machine steadily continues the active force of two flight chains, dismounting chain safety, rapid, convenient.The tight chain power that stressed consistent under its active force and the chain duty, two chains are subjected to is also consistent, thereby can grasp the tightness of two chains exactly.
