Background technology:
The vertical suction tube structure of using in the aluminum electrolysis industry electrode production at present mainly is made up of inner suction pipe and outer tube, by the rise and fall of the pulling of the electrical motor on driving or other equipment inner suction pipe, once stretches and finishes whole suction strokes.The shortcoming of such device is a very flexible, and suction stroke length causes inner suction pipe and outer sleeve lap long, and institute takes up space big, and the cost height is unsuitable for small-scale suction operation.
Summary of the invention:
The purpose of this utility model is: a kind of manual operations is provided, and the vertical suction tube of alerting ability height, compact conformation is used for small-scale suction operation.
The utility model is to constitute like this: it comprises outer sleeve (3), inner suction pipe (7), fixed pulley group (2) is fixed on the outer sleeve (3), and be connected with running block (4) by steel rope, running block (4) is connected by screw rod (9) with counterweight (5), handle (6) is fixed on the counterweight (5), and the lower end of counterweight (5) connects inner suction pipe (7); Material sucking mouth (8) flexibly connects with inner suction pipe (7); Be connected with circular nut joint (1) at the top of outer sleeve (3).
Described material sucking mouth (8) hangs on the hook (12) of inner suction pipe (7) by wire line thimble (11), and presses down locking with pressure handle (10).
It is 2 pulley system that running block (4), fixed pulley group (2) connect into multiplying power with steel rope.
During work, the operator spurs handle (6) driving running block (4) and moves up or down, and inner suction pipe (7) puts down thereupon or rises, and the distance that handle (6) moves is half of inner suction pipe 7 miles of relative movement.Counterweight (5) balance the weight of inner suction pipe (7) and material sucking mouth (8), moving of operator only needs to overcome the pulley system friction drag.Material sucking mouth (8) can select length to change according to the different work scope, has reduced the operation height.Only need rotate up pressure handle (10) during replacing wire line thimble (11) is unclamped from hook (12), take off then and get final product.
The beneficial effects of the utility model are: make manual operation convenient feasible, the action required space is little, and the cancellation of power driven system simultaneously also greatly reduces cost.
The specific embodiment:
Embodiment of the present utility model: fixed pulley group (2) goes up welding at outer sleeve (3) and fixes, running block (4) is connected by screw rod (9) with counterweight (5), and be connected with fixed pulley group (2) by steel rope, can slide up and down, handle (6) is fixed by bolts on the counterweight (5).Material sucking mouth (8) hangs over wire line thimble (11) on the hook (12) of inner suction pipe (7), by 11 lockings of the pressure handle on the turn material sucking mouth (10) pulling wire line thimble.It is 2 pulley system that inner suction pipe, movable pulley, fixed pulley group, counterweight connect into multiplying power with steel rope.Circular nut joint (1) is welded on the top of outer sleeve (3), and system is connected with external vacuum.
