Described spiral is paid driving mechanism and is constituted like this, hollow shaft (16) is installed in the sleeve (21) by bearing (17), gland (20), hollow shaft (16) internal fixation has copper nut (18), be installed with leading screw (19) in the copper nut (18), back cover nut (7) and fastening screw trip bolt (8) are equipped with in hollow shaft (16) bottom, can store lubricant oil in the hollow shaft (16) with lubricated leading screw and copper nut, when copper nut (18) rotated with hollow shaft (16), leading screw (19) promptly moved on its axial direction.
The following formation of described safe clutch mechanism, the clutch that on hollow shaft (16), is set with rotating band steel ball positioning hole trap (9), the back cover nut (7) of hollow shaft (16) bottom is holding in the palm clutch trap (9), cover (15) and clutch gland (12) connect with hollow shaft (16) with flat key (14) on the clutch, pressure spring (11) and steel ball (10) are loaded on and overlap on the clutch in (15) and the last equally distributed mounting hole of clutch gland (12), adjusting nut (13) is positioned on the clutch gland (12), have some adjustment fenestras on hollow shaft (16) and the sleeve (21), nut (13) Regulation spring pressure is respectively adjusted in rotation, reaches the purpose of adjusting driving torque.
The utility model description of drawings is as follows:
Fig. 1 is adjustable force moment electric spiral lifting (or push-and-pull) device structural drawing.
Now in conjunction with the accompanying drawings the utility model is further described.As shown in Figure 1, (1) motor wherein, (2) joining shaft, (3) connection seat, (4) variable speed transmission bearing, (5) casing, (6) zygote, (7) back cover nut, (8) fastening screw trip bolt, (9) clutch is trapped, (10) steel ball, (11) pressure spring, (12) clutch gland, (13) adjust nut, and (14) flat key overlaps on (15) clutch, (16) hollow shaft, (17) bearing, (18) copper nut, (19) leading screw, (20) gland, (21) sleeve.
In the embodiment shown in fig. 1, reducing gear adopts variable speed transmission bearing (4), this bearing (4) can be a BS type variable speed transmission bearing, it is installed in the casing (5), motor (1) acts on variable-speed bearing (4) by joining shaft (2), by zygote (6) power is reached safe clutch mechanism and then drives spiral and pay mechanism kinematic.Variable speed transmission bearing has bigger ratio coverage (single staged transmission ratio 6-60), so it is identical to change boundary dimension, the variable speed transmission bearing that velocity ratio is different, can change lifting technology parameter of the present utility model, to satisfy the requirement of different rising or falling speeds, be convenient to general, serial, the standardization of product.
Spiral is paid driving mechanism and is constructed as follows as shown in Figure 1: hollow shaft (16) is installed in the sleeve (21) by bearing (17), gland (20), hollow shaft (16) internal fixation has copper nut (18) and leading screw (19), hollow shaft (16) bottom is equipped with back cover copper nut (7) and locking Cock screw (8), makes can store lubricant oil in the hollow shaft (16) with lubricated leading screw (19), nut (18).
The safe clutch mechanism of adjustable force moment is installed on the hollow shaft (16), and its effect is the limit position limitation protection that overload protection and spiral lifting move.It constitutes as shown in Figure 1, rotating clutch trap (9) is housed on the back cover nut (7) of hollow shaft (16) bottom, cover (15) on the clutch, clutch gland (12) connects with hollow shaft (16) with flat key (14), pressure spring (11), steel ball (10) is contained in and overlaps in the mounting hole uniform on (15) and the clutch gland on the clutch, adjustable adjustment nut (13) is housed on the clutch gland (12), by the adjustment fenestra of offering on hollow shaft (16) top and the sleeve (21), can screw with loosening and adjust nut (13), reach and adjust the effect that spiral is paid driving torque, to satisfy the requirement of different spiral lifting (or push-and-pull) power.
The clutch of above-mentioned safe clutch mechanism is trapped and is evenly had 4-12 steel ball positioning hole on (9), also evenly have 4-12 mounting hole on cover (15) and the clutch gland (12) on the corresponding clutch, to be used to put steel ball (10) and pressure spring (11).
During work, motor drives variable speed transmission bearing by joining shaft and slows down, by zygote with transmission of power to the safe clutch mechanism that is installed on the hollow shaft, drive the spiral that is installed in it when hollow shaft rotates and pay the driving mechanism motion.This adjustable force moment electric spiral lift device can directly replace the used drving sprial lift device of balance crane, after tested, on probation, has reached desirable effect.
