Description
Technical field
The utility model relates to a kind of chain type bucket elevator, particularly relates to a kind of stretching device of chain type bucket elevator.
Background technology
In aluminum electrolysis industry, the chain type bucket elevator of carrying aluminium oxide to use, the tensioning mode of its afterbody transmission device mostly is the screw rod tensioning, this stretching device is to pass through rotating screw bolt, driving the bearing seat suspension bracket moves axially in the screw rod upper edge, the bearing seat suspension bracket then draws or the impeller-hub bearing moves in orbit by bearing pin is corresponding, thereby realizes tensioning or loosen the purpose of sprocket assembly.This stretching device is simple in structure, compact, reliable operation, but tensile force is uncontrollable, and over-tension causes the chain life-span to shorten easily.
Summary of the invention
The purpose of this utility model is: a kind of later-model sprocket wheel stretching device is provided, had both kept the advantage of former screw rod stretching device, can effectively control and regulate tensile force again, prolong the service life of parts such as chain.
The utility model is to constitute like this: it comprises screw rod (3), screw rod (3) cover is packed into and is rotated in the sleeve of supporting seat (4), rotation supporting seat (4) is connected with frame (13), end at screw rod (3) is connected with locating bush (2), locating bush (2) is close to the last anchor ring of rotation supporting seat (4), spring (10) and circular nut (12) are installed at the middle part of screw rod (3), and the two ends of spring (10) are supported on respectively on following anchor ring of rotation supporting seat (4) and the circular nut (12); The other end at screw rod (3) is connected with bearing seat suspension bracket (5), and bearing seat suspension bracket (5) is connected with bearing seat (7), and sprocket assembly (9) is installed on bearing seat (7), and bearing seat (7) is connected with guide rail (8), and guide rail (8) is connected with frame (13).
In above structure, screw rod (3) is connected with locating bush (2) by bearing pin (1); Be welded with gusset piece (15) on the rotation supporting seat (4), and be fixed on the frame (13) by gusset piece (15) and bolt arrangement; Screw rod (3) is connected with bearing seat suspension bracket (5), circular nut (12) by screw thread; Also have oval hole slot (14) on screw rod (3), screw rod (3) is connected with circular nut (12) with holding screw (11) by oval hole slot (14); Bearing seat suspension bracket (5) is connected with bearing seat (7) by bearing pin (6).
The principle of work of this mechanism is:
1. determine initial position.Definite principle of initial position is to guarantee that spring (10) has certain pre-tensile force, and leave enough adjustment leeway.The pre-tensile force that is added in spring (10) makes locating bush (2) compress the last anchor ring of rotation supporting seat (4) by the form of antagonistic force.
2. sprocket assembly (9) is carried out tensioning.Work and wearing and tearing along with sprocket assembly (9), its chain is elongated to fluff, need carry out tensioning, this moment rotating screw bolt (3), driving bearing seat suspension bracket (5) moves down on screw rod (3) vertically, bearing seat suspension bracket (5) is then gone up at track (8) by bearing pin (6) respective drive bearing seat (7) and is moved, thereby makes sprocket assembly (9) tensioning; When chain acts on tensile force on the sprocket assembly (9), during greater than the pre-tensile force sum of the deadweight of sprocket assembly (9) and spring (10), locating bush (2) is in quick condition, and with the trickle slit of last anchor ring appearance of rotation supporting seat (4), can judge that tensile force has reached setting value this moment.
It should be noted that if tensile force has reached in the time of still can not satisfying actual the requirement after the setting value, just need to regulate circular nut (12), give the bigger amount of compression of spring (10), be in the maximum functional stroke until spring (10).
3. sprocket assembly (9) is loosened.If need make sprocket assembly (9) when loosening, the rotation direction of screw rod (3) is opposite during with tensioning.
The beneficial effects of the utility model are: simple in structure, compact, tensile force can effectively be controlled and regulate to reliable operation, prolongs the service life of drive disk assemblies such as chain.
Description of drawings:
Fig. 1 is a scheme drawing of the present utility model.
The specific embodiment:
Embodiment of the present utility model: at first,, determine the size of a stretching device parts, especially will design the parameter of spring according to the situation of transferring power, such as material, rigidity, length, inside and outside footpath, steel wire diameter etc., and make parts.Secondly, install according to the diagram relation: the first, assembling frame (13) is contained in guide rail (8) on the frame (13); The second, assembling sprocket assembly (9) is contained in axle to parts such as sprocket wheels and goes up (chain can be installed in the 5th step); The 3rd, sprocket assembly (9) is contained on the bearing seat (7); The 4th, bearing seat (7) is installed on the guide rail (8); The 5th, bearing seat suspension bracket (5) and bearing seat (7) are coupled together (can go up the installation chain this moment at sprocket assembly (9)) with bearing pin (6); The 6th, rotation supporting seat (4) is installed on the frame (13) by gusset piece (15) with bolt, and is inserted in screw rod (3), then locating bush (2) is fixed on the screw rod 3 with bearing pin (1); The 7th, the 6th step stack-mounted assembly put into frame (13) after, spring (10) is enclosed within on the screw rod (3), and circular nut (12) is contained on the screw rod (3), more than form screw arbor assembly; The 8th, screw arbor assembly is connected with bearing seat suspension bracket (5); The 9th, adjustment guide rail (8) is positioned at the initial position on the frame (13), and adjusting shaft bearing suspension bracket (5) is positioned at the position on the screw rod (3); The tenth, swivel nut (12) compression spring (10) when meeting the requirements of predetermincd tension, inserts holding screw (11) in the oval hole slot (14) by the tapped bore on the circular nut (12), and fixedly the position of circular nut (12) gets final product.
