Abstract
The utility model relates to a screw rod pulley type transmission mechanism for an electric airing rod. A reversible motor (12) is arranged in a machine frame (4), a big belt pulley (10) is driven by a small belt pulley (11) on the reversible motor, and a nut and a thread are arranged in a middle hole of the big belt pulley. A screw rod (7) engaged with the thread penetrates through the middle hole of the big belt pulley (the nut), and one end of the screw rod (7) is connected with a movable block pulley (6). A fixed block pulley (5) is fixedly arranged on the machine rack. Two traction ropes (3, 8) respectively pass through the pulleys of the block pulleys and pass through a right pulley (2) and a right pulley (9) to the ends of an airing rod (1). The utility model has the characteristics of simple structure, and low manufacture cost, the pulleys are not convoluted by a rope, and the traction ropes are not convoluted. The utility model is mainly used for the transmission mechanism for the electric airing rod.
Description
The utility model relates to a kind of transmission mechanism of the electronic bar that dries in the air.
Having the transmission mechanism of the electronic bar that dries in the air now, generally is to drive the rotation of rope reel by motor by the worm screw speed change gear, and the forward or reverse of forward-reverse switch control motor makes rope reel receipts rope or puts rope, reaches the purpose that control is dried in the air the bar rising or descended.This transmission mechanism, the easy shortcoming such as winding of rope when having the counter-rotating of manufacturing cost height, reel.
The purpose of this utility model is to overcome the shortcoming of existing transmission mechanism, and a kind of transmission mechanism of screw mandrel pulley-type is provided, and makes that it is simple in structure, low cost of manufacture, traction rope do not twine.
The purpose of this utility model is achieved in that in frame, one reversible motor is installed, small belt pulley on the motor directly or indirectly drives big belt pulley, the big belt pulley mesopore is shaped on nut thread, screw mandrel with threaded engagement, pass the mesopore of big belt pulley, the one end connects running block, the fixed pulley group is fixedly mounted on the frame, article two, the end of rope of pulling strings lies in respectively on the fixed pulley group seat, the other end respectively the pulley on assembly pulley again through the pulley at the inner two ends of frame two ends to the bar that dries in the air.Motor drives big belt pulley (nut) forward or reverse by small belt pulley, thereby drive screw mandrel to the right or to left movement, make running block also to the right or to left movement, distance between running block and the fixed pulley group increases thereupon or reduces, speedup effect by assembly pulley is tightened up two pull ropes simultaneously or is loosened, and drives the bar that dries in the air and keeps level to move upward or downward.
The utility model, the assembly pulley speed increasing ratio can choose 2～10, and promptly the pulley number average of running block and fixed pulley group is chosen 2～10; On frame, also the bar limit switch that dries in the air can be installed, the work of limit switch control motor.
The utility model has following characteristics:
(1) Motor Drive nut rotation makes the screw mandrel axially-movable;
Therefore (2) screw mandrel only is subjected to pulling force, can make very long and buckling can not take place;
(3) utilize movable and fixed pulley group speedup, produce, effectively utilize the space than the bigger stroke of screw mandrel motion;
(4) left and right pull rope synchronism is good, the level when helping keeping drying in the air the bar ascending, descending, and the traction rope can not twine;
(5) simple in structure, low cost of manufacture.
Description of drawings: Fig. 1 and Fig. 2 are the utility model structure principle chart, and wherein Fig. 1 is a front view, and Fig. 2 is a vertical view.Among the figure, (1) bar that dries in the air, (2) left chain wheel, (3) left pull rope, (4) frame, (5) fixed pulley group, (6) running block, (7) screw mandrel, (8) right pull rope, (9) right pulley, (10) big belt pulley and nut, (11) small belt pulley, (12) reversible motor.
Embodiment: with reference to accompanying drawing, in cuboid metal machine frame (4), install reversible motor (12), the small belt pulley on the motor (11) has a through hole by belt transmission big belt pulley (10) in the middle of the big belt pulley, and mesopore is shaped on nut thread.With the screw mandrel (7) of threaded engagement, pass the mesopore of big belt pulley, the one end is connected with running block (6), and fixed pulley group (5) is fixedly mounted on the frame.The pulley of fixed pulley group and moving sliding group is all got 4.One end of a left side pull rope (3) and right pull rope (8) lies in respectively on the fixed pulley group seat, the other end respectively the pulley on assembly pulley again through the left chain wheel (2) at two ends, frame inside and right pulley (9) two ends to the bar that dries in the air (1).Owing on the assembly pulley 4 fixed pulleys and 4 movable pulleys are arranged, so every pull rope is all through two movable pulleys and two fixed pulleys, speed increasing ratio is 4, that is to say, if the mobile to the left or to the right 10cm of screw mandrel, the bar that then dries in the air keep level to do to rise or decline 40cm.Its operation principle is: connect motor power, by " rising " button, motor just changes, small belt pulley rotates by belt drives big belt pulley (nut), nut rotates screw mandrel is moved right, simultaneously also driving running block moves right, because the fixed pulley group is fixedly mounted on the frame, so the distance between running block and the fixed wheel group increases thereupon, keep level to do ascending motion thereby drive the bar that dries in the air, otherwise, if by " decline " button, motor dwindles the distance between running block and the fixed pulley group, and owing to the effect of gravity to the bar that dries in the air, the bar that dries in the air keeps level to do descending motion equally.
On the basis of the foregoing description, can the bar limit switch that dry in the air be installed on frame, when the bar that dries in the air rose to predetermined altitude, motor power was cut off in the limit switch action, controlled the lifting height of the bar that dries in the air automatically.
Claims (3)
