Abstract
The invention discloses an over-speed protection brake for hoisting equipment. A Mounting plate is arranged on a drum frame which is on a side of a drum; a ratchet is arranged on an encircle end of the mounting plate where the drum juts; a braking pawl is arranged on the mounting plate beside the ratchet; a driving mechanism of the braking pawl is arranged on the mounting plate. The ratchet is a two-piece structure, which is connected with a folding spring through a screw and enclasps the drum; a layer of frictional brake plate is arranged between the drum and the ratchet, which is used for absorbing impact force of the brake during working and reducing impact in braking process. The brake pawl is promoted by the driving mechanism of the brake pawl and is inserted into a trough of the ratchet, which causes the ratchet and the drum to break off and cut off power simultaneously. By adopting a combination of controlling chip and the structure of the ratchet and the brake pawl, damages of any link before the drum can be protected by protecting the drum. The invention is characterized by strong reliability and high security.
Description
Technical field
The present invention relates to a kind of fender guard of weight-lifting equipment, specifically relate to a kind of overspeed protected brake of weight-lifting equipment.
Background technology
The grave accident of weight-lifting equipment such as hoisting crane, electric block is malfunctioning because of lifting motor off-axis, service brake often, and the weight hypervelocity tenesmus that the gear tooth breakage of retarder or intermediate connector get loose or the like and to cause causes the grave accident of equipment, personal injury.In the prior art, the protection drg of weight-lifting equipment has a lot of forms, and its control structure is too complicated mostly, manipulates very inconveniently, and the braking effect that has is not satisfactory.
Summary of the invention
The present invention solves above-mentioned existing in prior technology technical matters, and a kind of overspeed protected brake of weight-lifting equipment is provided.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals: a kind of overspeed protected brake of weight-lifting equipment, comprise the reel that is arranged in the reel stand, on the reel stand of described reel one side the installation base plate is set, described reel stretches out the outer rounded ends that base plate is installed ratchet is set, on the installation base plate on ratchet side the braking ratchet is set, the driver train of braking ratchet is arranged on to be installed on the base plate; Described ratchet is two chip architectures, is connected with disk spring and holds tightly on reel by screw, is provided with one deck friction brake wafer between reel and the ratchet, and the impulsive force when being used for absorption brake work reduces the impact in the braking procedure; The driver train of described braking ratchet comprises the electromagnet that is connected on the braking ratchet, the control chip of described electromagnet comprises rectifying circuit, comparator circuit and control circuit, wherein external source is comparator circuit and control circuit power supply by rectifying circuit, drum speed signal and reel nominal speed compare by comparator circuit, and both comparative results are exported control signal by control circuit.Gather the drum speed signal near switch on the reel, comparator circuit compares, in case drum speed is during greater than the reel nominal speed, control circuit sends actuating signal, and electromagnet begins action, promotes the braking ratchet and inserts in the groove of ratchet, make ratchet and reel stall, and cut off the electricity supply simultaneously.
The present invention adopts control chip and click structure to organically combine, and by end---the reel of protection weight-lifting equipment, can both play a protective role to the damage of the arbitrary link of reel fwd, has characteristics such as good reliability, safety height.
Description of drawings
Fig. 1 is a kind of main TV structure scheme drawing of the present invention;
Fig. 2 is a kind of left TV structure scheme drawing of the present invention;
Fig. 3 is a kind of structural representation of control chip circuit of the present invention.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment: referring to Fig. 1 and Fig. 2, the present invention is provided with reel 1 in reel stand 7, be provided with on the reel stand 7 of reel one side base plate 6 is installed, reel 1 stretches out the outer rounded ends that base plate 6 is installed ratchet 2 is set, ratchet is two chip architectures, is connected with disk spring and holds tightly on reel by screw, is provided with one deck friction brake wafer 3 between reel 1 and the ratchet 2, impulsive force when being used for absorption brake work reduces the impact in the braking procedure; Braking ratchet 4 is set on the installation base plate 6 on ratchet 2 sides, and the driver train of braking ratchet 4 is arranged on to be installed on the base plate 6, comprises the electromagnet 5 that is connected on the braking ratchet 4; Referring to Fig. 3, the control chip of electromagnet comprises rectifying circuit, comparator circuit and control circuit, wherein external source is comparator circuit and control circuit power supply by rectifying circuit, drum speed signal and reel nominal speed compare by comparator circuit, and both comparative results are exported control signal by control circuit.
Principle of work of the present invention is: during weight-lifting equipment work, the reel rotation drives suspension hook and weight up-and-down movement, gathering the drum speed signal conveys near switch and give comparator circuit on the reel, comparator circuit compares drum speed and nominal speed, if drum speed is during less than nominal speed, the control circuit of chip does not send actuating signal, and overspeed protected brake is not worked; In case because of the arbitrary link in reel front (gear tooth breakage of, retarder malfunctioning or intermediate connector get loose etc.) when causing drum speed (suspension hook and weight quicken tenesmus) greater than nominal speed as lifting motor off-axis, service brake; the control circuit of chip sends actuating signal; electromagnet begins action; promoting the braking ratchet inserts in the groove of ratchet; make ratchet and reel stall; and cut off the electricity supply simultaneously, thereby prevent the tenesmus of suspension hook and weight, protected the safety of equipment, the person.
At last, should be pointed out that above embodiment only is the more representational example of the present invention.Obviously, technical scheme of the present invention is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
