Abstract
The utility model relates to a relaxing device for a brake of a toothless traction machine, which is composed of a fixing bracket, floating bracket, an electromagnet and friction columns. The friction columns which are positioned at both sides of a brake disk are fixedly connected with an armature and the floating bracket respectively, a sleeve surface which is connected with a handle to form an integrative structure is fixed to the axial direction of each friction column, a diagonal wedge is arranged on the sleeve surface and is embedded in a diagonal wedge trough of the end surface of an iron core, and the diagonal wedge can do sliding action according to the rotation of the handle; so the friction columns can drive the armature to be disengaged from the brake disc; thereby, the brake releasing purpose is realized. The utility model can cause the toothless traction machine to be like to a tooth traction machine to be provided with a manual brake releasing device, so the brake releasing purpose can be realized without an emergency power supply; thus, the equipment cost is lowered.
Description
The utility model relates to a kind of anodontia traction machine brake, especially its a kind of device that declutches.
In order to guarantee the safe operation of elevator traction machine, must adopt electricity loss brake, existing have the tooth towing machine mostly to adopt the lever mode to declutch.Anodontia towing machine does not have speed reduction gearing, but moves with the through-coupling mode, so the lock torque of its drg is than the much bigger of tooth arranged.Declutch with the lever mode, its fulcrum is to making the force distance excessive to the ratio of point of action distance with fulcrum, so be difficult to realize manually declutching, therefore anodontia towing machine all is to declutch with emergency source of electrical power, has so just increased the lift facility cost.
The purpose of this utility model is the defective that is at prior art, makes anodontia towing machine also as the tooth towing machine is arranged, and without emergency source of electrical power, but uses manual brake release, thereby reduces the overall cost of lift facility.
Task of the present utility model is achieved in that the device that declutches of this anodontia traction drg, be by fixed support, floating bracket, guide pillar, electromagnet, armature and friction post are formed, the friction post that is positioned at brake disc two sides fixes with armature that is sleeved on the guide pillar limit and floating bracket respectively, guide pillar is installed on the fixed support by axle sleeve, the compression spring that compresses mutually with armature is housed in the blind hole of iron core, between floating bracket and fixed support, retracing spring is housed, under electromagnet dead electricity or "on" position, by the side-to-side movement of armature and the effect of retracing spring, drive rubs the control post in brake disc two sides relatively or move toward one another, the friction post is pushed up mutually with brake disc or is separated.The sleeve that fixedly has handle at friction post one end, a wedge is arranged on the sleeve section, a wedge groove is arranged on the corresponding with it end face of iron core, wedge can slide with the rotation of handle in the wedge groove, thereby driving armature moves to iron core with the friction post, the purpose that declutches to reach friction post disengaging brake disc is equipped with torsion spring between sleeve section and iron core, reset after external force is eliminated to guarantee handle.
The anodontia towing machine of the utility model is not having not need emergency source of electrical power under the speed reduction gearing situation, can be as the tooth towing machine is arranged, under the dead electricity situation, availablely manually declutch, and greatly reduce the lift facility cost like this, guaranteed the elevator reliability of operation.
Accompanying drawing is a kind of embodiment of the present utility model, and the utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 removes A behind icon 1-nut and the sleeve handle 2 to view among Fig. 1.
Shown in the accompanying drawing, the device that declutches of this anodontia towing machine is made up of iron core 5, coil 6, armature 8 and friction post 10, the friction post 12 of fixed support 11, floating bracket 15, guide pillar 7, electromagnet.Be positioned at the friction post 10 of brake disc 18 2 sides, friction post 12 is fixing with armature 8 and floating bracket 15 respectively, and with caging bolt 19, spacing between 19 ' scalable they and the brake disc 18, one end of guide pillar 7 is captiveed joint with 5 usefulness holding screws unshakable in one's determination, the other end is installed on the fixed support 11 by axle sleeve, and can make sway vertically, armature 8 and floating bracket 15 are sleeved on the guide pillar 7, between fixed support 11 and the floating bracket 15 retracing spring 13 is housed, in unshakable in one's determination 5 blind hole compression spring 9 these compression springs 9 are housed and compress mutually with armature 8, fixed support 11 fixes with the end cap 14 of electrical motor 1.
Handle with sleeve welds mutually axially fixes by nut 1 and friction post 10, and an end of torsion spring 4 is inserted in the sleeve end face, and the other end is inserted in unshakable in one's determination 5.A wedge is arranged on the sleeve section of handle 2, a wedge groove 17 is arranged on the corresponding with it end face of iron core 3, wedge and wedge groove 17 are circular arc, and concentric with friction post 10, and handle 2 running inclined wedges can slide in wedge groove 17.
When coil 6 energisings, armature 8 is because the effect of electromagnetic force, the thrust that overcomes compression spring 9 is inhaled to unshakable in one's determination 5, drive friction post 10 and break away from brake disc 18, meanwhile, floating bracket 15 drives armature 8 and floating bracket 15 and slides to the opposite sense of former armature 8 motions under the effect of retracing spring 18, and make friction post 12 also break away from brake disc 18 simultaneously, so finished the electronic overall process that declutches.When coil 6 dead electricity of drg iron core 5, under the effect of three compression springs 9, friction post 10 that joins together with armature 8 and the friction post 12 that joins together with floating bracket 15 be successively towards brake disc 18 motions, and tightly withstand.Under the crunch of spring 9, the friction by between two friction posts and the brake disc 18 produces lock torque.
When needing, turning handle 2, wedge slides in wedge groove 17, make friction post 10 be with armature 8 toward moving left, be close to unshakable in one's determinationly 5 the time when armature 8, handle 2 can not rotate again, at this moment the post 10 that rubs unclamps with brake disc 18, meanwhile, retracing spring 13 is turned right and is pushed away, and makes floating bracket 15 drive friction post 12 disengaging brake discs 18 and finishes the process of declutching.Release handle 2, torsion spring 4 reset handle 2, and friction post 10 withstands brake disc 18 with friction post 12, realizes braking.
Be connected with handle 2 with brake steel wire rope one end that is similar to bicycle, the other end is installed on the remote exercisable position, just can be under no machine room situation, and the distance control towing machine declutches.
The utility model has been set up manual brake release, does not need emergency source of electrical power to reach and declutches, and has reduced the lift facility cost, and the application of residential lift is had positive meaning.
