Abstract
The utility model discloses a manual releasing device of an external-brake-type conical rotor lifting motor. The manual releasing device of the external-brake-type conical rotor lifting motor comprises a push rod, a thrust bearing, a force conducting disc, a connection mounting plate and a manipulating lever, wherein the connection mounting plate is fixed on a brake back cover of the lifting motor, a through hole is formed on the position of the connection mounting plate, which corresponds to the position of the motor shaft, the push rod is arranged in the through hole in a penetrating mode, the tail end of the push rod is sequentially provided with the thrust bearing and the force conducting disc, and one end of the manipulating lever is connected with the force conducting disc. By arranging the manual releasing device on the external-brake-type conical rotor lifting motor, a suspension object can be lift down simply through manual operation with no need of restarting the motor; and when the lift-down speed is too fast, the lift-down speed can be regulated by changing the acting force applied to the manipulating lever.
Description
Technical field
The utility model relates to the bridge motor field, specifically, is a kind of outer formula cone rotor bridge motor hand release of stopping.
Background technology
The cone rotor bridge motor has two kinds of brake structure forms.A kind of formula of stopping in being is mainly used in the following motor of 7.5KW; A kind of is the outer formula of stopping, and is mainly used in the above motor of 13KW.
The principle of work of two kinds of structural electromotors is identical, all that after energising, the stator and rotor surface produces electromagnetic attraction, because the stator and rotor surfaces is all taper, electromagnetic attraction can be decomposed into axially and two power radially, axial component wherein can draw rotor and brake wheel moves to the microcephaly, with the retarding spring compression, brake wheel is thrown off with the braking bonnet simultaneously, and motor begins rotary work; After the motor dead electricity, electromagnetic attraction disappears, the retarding spring bounce-back, and traction rotor and brake wheel move to pipe reducer, thus brake wheel tightly contacts with the braking bonnet, produces braking.Though motor shaft has the gravity that hangs thing to produce torque, because the opposing torque that brake wheel is arranged exists, weight can not fall.
The problem that existing cone rotor bridge motor exists is, when needs will hang thing and put down, only has energising again, and motor reversal just can put down hanging thing, can't realize that manually will hang thing puts down.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide a kind of outer formula cone rotor bridge motor hand release of stopping, and can't realize manually hanging the problem that thing puts down to solve the existing outer formula cone rotor bridge motor of stopping.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of outer formula cone rotor bridge motor hand release of stopping, comprise push rod, thrust baring, force transmiting disk, connection plate and bar handle, described connection plate is fixed on the braking back cover of bridge motor, through hole is offered in position corresponding with motor shaft on the connection plate, described push rod is arranged in through hole, end at push rod is provided with thrust baring and force transmiting disk successively, and an end of described bar handle connects force transmiting disk.
In the utility model, further, also comprise retracing spring, described retracing spring is set on push rod, is provided with annular boss on push rod, is provided with baffle ring in the through hole of connection plate, one end of described retracing spring is butted on annular boss, and the other end of retracing spring is butted on baffle ring.
In the utility model, further, described bar handle is " 7 " font handle, and the middle part of bar handle is rotationally connected by bearing pin and the support that is arranged on the connection plate.
Beneficial effect: by installing hand release of the present utility model additional on the formula cone rotor bridge motor of stopping outside, when needs will hang thing and put down, do not need to restart motor, only need a M/C can realize to hang thing and put down; Fall when too fast when hanging thing, can regulate hanging the thing falling speed by the amount of force that change is applied to bar handle.
Description of drawings
Fig. 1 is the structural representation of the existing outer formula cone rotor bridge motor of stopping;
Fig. 2 is structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is done further and explained.
As illustrated in fig. 1 and 2, the outer formula cone rotor bridge motor hand release of stopping of the present utility model comprises push rod 1, thrust baring 2, force transmiting disk 3, connection plate 4 and bar handle 5.Connection plate 4 is fixed on the braking back cover 6 of bridge motor, and through hole 8 is offered in position corresponding with motor shaft 7 on connection plate 4, and through hole 8 places are provided with baffle ring 11.Push rod 1 is arranged in through hole 8, is provided with annular boss 10 on push rod 1.Retracing spring 9 is set on push rod 1, and an end of retracing spring 9 is butted on annular boss 10, and the other end of retracing spring 9 is butted on baffle ring 11.End at push rod 1 is provided with thrust baring 2 and force transmiting disk 3 successively.Bar handle 5 is " 7 " font handle, and the middle part of bar handle 5 is rotationally connected by bearing pin 12 and the support 13 that is arranged on connection plate 4, and an end of bar handle 5 connects force transmiting disk 3.
The principle of work of this hand release is, apply a downward power F for bar handle 5, bar handle 5 can produce a thrust P who promotes force transmiting disk 3 left, this thrust P passes to push rod 1 by thrust baring 2 with power, push rod 1 passes to motor shaft 7 with power, the rotor 14 of bridge motor and brake wheel 15 move to the microcephaly, thereby brake wheel 15 and braking back cover 6 are thrown off, and hang thing and can fall under Action of Gravity Field; When hanging the thing speed of fall when too fast, reduce or remove power F, retracing spring 9 can push away push rod 1 to the right, and push rod 1 separates with motor shaft 7, motor shaft 7 is being pressed in brake wheel 15 again under the bounce-back of retarding spring 16 on braking back cover 6, and hanging the thing falling speed can reduce even to stop immediately.Adopting suitably, the power F of size just can put down gently with hanging thing.
The above is only preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
