Abstract
The utility model discloses a gate hoist capable of indicating the hoisting height of a gate. A set of reduction gear having a large speed ratio and rotating coaxially with a screw rod is arranged in a machine base of the hoist; an input shaft of the reduction gear is connected with the screw rod of the hoist; scale display is arranged on an outer ring of an output mechanism; the movement of the grate is converted into the slow rotation of the output mechanism of the reducing gear; the opening degree of the gate can be displayed from the scale.
Description
The utility model belongs to the small-sized headstock gear that a kind of field irrigation is used.
At present, known small-sized headstock gear mostly is worm-type open-close machine, can be divided into two kinds according to its motion mode: a kind of is that nut is fixed, and screw motion type, gate directly are connected on the screw rod, move up and down with screw rod.Because of the general open space of its screw rod, be commonly called as and be the open type headstock gear; Another kind is that screw rod is fixed, and the nut mobile model is fixed with sleeve pipe on the nut and by sleeve and gate connection, gate moves up and down with nut.Because of its screw rod, nut is covered by sleeve pipe and is kept away, and is commonly called as to be closed headstock gear.The open type headstock gear can show the Lift of gate intuitively from the lifting distance of screw rod, yet but easily for dust storm corrodes, is difficult for maintenance; Closed headstock gear is easy to maintain the Lift that but can't show gate intuitively, makes the water pipe personnel feel very much inconvenience.
The purpose of this utility model is: a kind of closed headstock gear that can show the gate opening height is provided.
The purpose of this utility model is achieved in that the large speed ratio deceleration device that a cover and screw coaxial transmission are set in closed headstock gear support, the power shaft of deceleration device connects mutually with the screw rod of headstock gear, and corresponding scale is arranged on the outer ring of deceleration device output mechanism; Like this, the displacement of gate will be converted to the slow revolution of deceleration device output mechanism around the support center, just can demonstrate the Lift of gate from the scale.
The utility model is by setting up the large speed ratio deceleration device and in the mode of deceleration device output mechanism outer ring scale, having shown the Lift of gate intuitively in support, the water service pipe personnel have brought convenience.
Below by specific embodiments and the drawings the utility model is illustrated in detail.
Fig. 1 is a kind of headstock gear that adopts the small teeth number difference planet gear deceleration device.Fig. 2 is a kind of headstock gear that adopts the harmonic gear deceleration device.
Among Fig. 1,1 support, 2 nuts, 3 screw rods, 4 keys, 5 bearings, 6 eccentric bushings, 7 pins, 8 planetary gears, 9 internal gears, 10 wrench.
Eccentric bushing (6) is fixed on screw rod (3) top with key (4), and the outer garden of eccentric bushing (6) and planetary gear (8) endoporus are for movingly, and pin (7) is fixed on the support (1), and corresponding scale is carved with in internal gear (9) outer ring.In this example, the internal gear number of teeth is 100, and the planetary gear number of teeth is 99, and speed reducing ratio is 1: 100.Certainly, scale also can be engraved on the support.
Among Fig. 2,1 support, 2 nuts, 3 screw rods, 4 keys, 5 bearings, 11 wave producers, 12 flexbile gears, 13 have just been taken turns, 10 wrench.
Wave producer (11) is double wave shape, is fixed on screw rod (3) top with key (4), and flexbile gear (12) is screwed on support (1), and just wheel (13) is as output mechanism, and there is corresponding scale its outer ring.Herein, the flexbile gear number of teeth is 118, and just tooth number is 200.Scale also can be engraved on the support.
If external gear is fixed, allow planet carrier or flexbile gear as output mechanism in above-mentioned two examples, effect is just the same.
Claims (3)
1, a kind of headstock gear that can show the gate opening height.It is characterized in that: the large speed ratio deceleration device of a cover and screw coaxial transmission is set in closed headstock gear support, and the power shaft of deceleration device connects mutually with the screw rod of headstock gear, and corresponding scale is arranged on the outer ring of deceleration device output mechanism.
2, headstock gear as claimed in claim 1 is characterized in that: deceleration device wherein is a planetary speed reducer with small tooth number difference, and the power shaft of deceleration device is fixed on screw rod top.
3, headstock gear as claimed in claim 1 is characterized in that: deceleration device wherein is a harmonic speed changer, and the wave producer of deceleration device is fixed on screw rod top.
