Abstract
The utility model discloses an inner braking type taper rotor hoisting motor manual releasing device. The device comprises a connecting bushing, wherein the connecting bushing is arranged between a stator rack and a breaking rear cover of the hoisting motor, an operational handle is arranged on the connecting bushing, an angle contact ball bearing and a bearing stopping ring are arranged at the position of the rotary shaft of the hoisting motor, which corresponds to the operation handle, and a dowel disk is sleeved outside the angle contact ball bearing and the bearing stopping ring and connected to the operation handle. The device is arranged on an inner braking type taper rotor hoisting motor, the motor is not required to be restarted when hoisted articles are put down, articles are put down through the manual operation, and the action exerted on the operation handle is changed to adjust the dropping speed of articles when articles fall down quickly.
Description
Technical field
The utility model relates to the bridge motor field, specifically, is the formula cone rotor bridge motor hand release of stopping in a kind of.
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 the formula cone rotor bridge motor hand release of stopping in a kind of, can't realize manually hanging the problem that thing puts down to solve the formula cone rotor bridge motor of stopping in existing.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
The formula of stopping in a kind of cone rotor bridge motor hand release, comprise coupling bush, described coupling bush is arranged between the out frame and braking bonnet of bridge motor, bar handle is set on coupling bush, position corresponding with described bar handle on the turning cylinder of bridge motor is provided with angular contact ball bearing and end ring, the sheathed force transmiting disk in the outside of described angular contact ball bearing and end ring, described force transmiting disk connects bar handle.
In this practicality, further, described bar handle is " 7 " font handle, one end of described bar handle is arranged on outside coupling bush, the other end of bar handle stretches in coupling bush, the middle part of bar handle is rotationally connected by bearing pin and coupling bush, and described force transmiting disk stretches into the interior end of coupling bush with bar handle and is connected.
Beneficial effect: by installing hand release of the present utility model additional on the interior formula cone rotor bridge motor of stopping, 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 formula cone rotor bridge motor of stopping in existing;
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 formula cone rotor bridge motor hand release of stopping in of the present utility model comprises coupling bush 5, and coupling bush 5 is arranged between the out frame 6 and braking bonnet 7 of bridge motor, and bar handle 1 is set on coupling bush 5.Bar handle 1 is " 7 " font handle, and an end of bar handle 1 is arranged on coupling bush 5 outsides, and the other end of bar handle 1 stretches in coupling bush 5, and the middle part of bar handle 1 is rotationally connected by bearing pin 12 and coupling bush 5.The position corresponding with bar handle 1 is provided with angular contact ball bearing 4 and end ring 3 on the turning cylinder 8 of bridge motor, the sheathed force transmiting disk 2 in the outside of angular contact ball bearing 4 and end ring 3, force transmiting disk 2 stretch into the interior end of coupling bush 5 with bar handle 1 and are connected.
The principle of work of this hand release is, be positioned at the downward power F in one of end in coupling bush 5 outsides for bar handle 1, the end that is positioned at coupling bush 5 inboards at bar handle 1 can produce a thrust P to the right, this thrust P can pass to 3 power by force transmiting disk 2, angular contact ball bearing 4 and end ring the turning cylinder 8 of bridge motor successively, turning cylinder 8 compression brake springs 9, rotor 10 and brake wheel 11 move to the microcephaly, thereby brake wheel 11 and braking bonnet 7 are thrown off, hang thing and can fall voluntarily under Action of Gravity Field.When hanging the thing falling speed when too fast, reduce or remove power F, turning cylinder 8 can be pressed in brake wheel 11 under the bounce-back of retarding spring 9 on braking bonnet 7, and hanging the thing falling speed can reduce even to stop immediately.Adopt suitable power F, just can put down gently 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.
