Abstract
The utility model belongs to a safe protector for rescuing people to lower places from high-rise buildings or objects similar to the high-rise buildings. The motor of the safe protector drives a drum wound with a safety rope to rotate through a worm-wheel worm reducer. Because the safe protector can realize four-stage brake control comprising the direct-current braking of the motor, the self locking of the reducer, the closing of a normally-opened brake and the power-off closing of a normally-closed brake, the utility model can ensure the personal safety of persons joining training and eliminate the persons' injuring, disabling and dying accidents caused by improper safety protection.
Description
The utility model belongs to lifesaving safety guard use for taking people downstairs on high-rise or the analogue.
When People's Armed Police and public security fire-fighting personnel carry out climbing height training, need safety guard.Existing method for security protection is the back waistband place that safety rope is fixed on the personnel of ascending a height; hold safety rope with hand downwards by reversing wheel on the ground by several soldiers; owing to be that the several people carries out manual control simultaneously, mismate is easy to cause personnel's permanent disability even fatal accident to take place.
The purpose of this utility model provides a kind of safety rope self-retention fender guard of used for climbing height training, to guarantee trainer's personal safety.
The utility model is to realize like this.A kind of safety rope self-retention fender guard; one side of motor (9) axle is fixed with normally engaged brake (10); input shaft at the opposite side motor shaft gearing speed-reducer (7) of motor (9); the output shaft transmission of retarder (7) is fixed with the axle (12) of cylinder (6); the opposite side of axle (12) is installed on the bearing seat (3); the end of axle (12) is fixed with normally disengaged brake (1), is wound with safety rope (5) on the cylinder (6).On the axle (12) between cylinder (6) and the bearing seat (3), sr (11) is installed.The downside of cylinder (6) is equipped with limitation travel switch (2).
Comparing the beneficial effects of the utility model with the existing method for security protection of ascending a height is because this device can be realized motor braking; the retarder self-locking; the normally disengaged brake closure; the level Four control of braking of normally engaged brake power-failure close; make the life safety of participating in the trainer that reliable guarantee arranged, stopped because of personnel's wound of the improper generation of safety guard-safeguard, residual, the accident of dying.In addition, because this apparatus structure is simple, easy to install, with low cost.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Be described further below in conjunction with embodiment.
The model of motor (9) is Y802-4, retarder (7) is selected pot wheel pot bar type structure for use, model is the WS1-80 type, normally disengaged brake (1) model is the DLTZ-6 type, the normally engaged brake model is the DLTZ-160 type, what sr (11) adopted is the general part of selling on the market, and its model is decided according to the external diameter of axle (12).
One of safety rope (5) is fixed on the waist rear portion of participating in the climbing height training personnel, reels and be fixed on the cylinder (6) in the other end.This device is installed in the high-rise building top of training.After motor (9) started, normally engaged brake (10) was opened, brake off, and the worm screw input shaft of motor (9) gearing speed-reducer (7), the worm gear part transmission shaft (12) of retarder (9) rotates, and cylinder (6) is rotated, safety rope (5) rising of being reeled.When needs control safety rope descends, motor (9) counter-rotating.When accident occurring midway, accident signal is sent signal by the fixedly sensing device that is located at the trainer top, and the control motor is sent into direct current (DC), motor is stopped operating, while drg (10) power-off brake closure, retarder (7) self-locking, normally disengaged brake (1) closure forms the level Four braking.The circuit control part can be designed to controlled in wireless, sr (11) also can be installed between cylinder (6) on the axle (12) and normally disengaged brake (1) realize having line control.The cylinder downside is equipped with limitation travel switch (2), with the position of restriction halliard, and fixing conductor rope ring (4) also on the cylinder (6), evenly distributed when safety rope is twined.Device of the present utility model is fixed on the chassis (8).
Claims (3)
1, a kind of safety rope self-retention fender guard; a side that it is characterized in that motor (9) axle is fixed with normally engaged brake (10); input shaft at the opposite side motor shaft gearing speed-reducer (7) of motor (9); the output shaft transmission of retarder (7) is fixed with the axle (12) of cylinder (6); the opposite side of axle (12) is installed on the bearing seat (3); the end of axle (12) is fixed with normally disengaged brake (1), is wound with safety rope (5) on the cylinder (6).
2, safety rope self-control fender guard according to claim 1 is characterized in that on the axle (12) between cylinder (6) and the bearing seat (3) sr (11) being installed.
3, safety rope self-control fender guard according to claim 1 is characterized in that the downside of cylinder (6) is equipped with limitation travel switch (2).
