Abstract
The invention relates to the field of safety protective tools, in particular to a drum wheel for a differential speed automatic controller during high-altitude operation. The invention discloses a drum wheel for a differential speed automatic controller. The drum wheel has an integrated structure; one side of the drum wheel is in a circular cavity shape, and the other side of the drum wheel is divided into four fan-shaped cavities uniformly by two reinforcing ribs which are vertical mutually; a thread hole through which a hanging belt passes is formed on any one reinforcing rib; and a shaft hole through which a central shaft passes is formed in the center of the drum wheel. Due to the adoption of the drum wheel with the integrated structure, the integral differential speed automatic controller is more stable, and the volume of the drum wheel can be reduced substantially to reduce the volume of the differential speed automatic controller, so that the differential speed automatic controller is convenient to carry and the high-altitude operation is also convenient. In addition, the service life of the differential speed automatic controller can be prolonged substantially.
Description
Technical field
The present invention relates to a kind of safety protective tools field, relate in particular to a kind of drum of the poor automatic controller of speed during for work high above the ground.
Background technology
Now, along with the development of science and technology, ground space more and more less, a large amount of high buildings and large mansions are rised sheer from level ground.Along with the increase of height, comparatively simply work at ordinary times, such as cleaning glass or assembling certain device etc., owing to being work high above the ground, so that such work becomes more difficult.The poor auto-control safety hook of thing followed high-speed has solved above-mentioned difficulty, but the general poor auto-control safety hook of high-speed, volume is larger, complicated structure, thus so that cost is higher.Particularly drum is to be assembled by two and half drums process, and this is just so that the poor auto-control safety hook of whole high-speed becomes very unstable, and access times are many will so that drum breaks down, bring potential safety hazard for the construction workman.And drum so that whole drum is larger, takies larger space through assembling, so that the volume of the poor auto-control safety hook of whole high-speed is larger, weight is also just larger, very inconvenient carrying.
Summary of the invention
The defective that the present invention exists when solving work high above the ground provides a kind of drum of the poor automatic controller of speed of integrative-structure.
Its concrete technical scheme is: the drum of the poor automatic controller of a kind of speed, and described drum is structure as a whole; The rounded cavity-like of one side of described drum, the opposite side of drum is evenly distributed into four fan-shaped cavities by two orthogonal reinforcements; Described any reinforcement is provided with a through wires hole that can supply suspender belt to pass; The center of described drum offers an axis hole that can supply central shaft to pass.
Be preferably, described drum circular cavity one side is fixedly connected with ratchet.
Be preferably, be provided with clockwork spring in the circular cavity of described drum, an end of clockwork spring is fixed on the central shaft, and the other end is fixed on the drum.
Be preferably, be wound with suspender belt on the outer ring face of described drum.
The poor automatic controller of this type of speed comprises housing and is arranged on the interior drum of housing, is provided with central shaft in the described housing; Be socketed with drum, ratchet on the described central shaft, drum is fixedly connected with ratchet; Described drum is structure as a whole, and is provided with clockwork spring in the described drum, and an end and the central shaft of clockwork spring are fixed, and the other end of clockwork spring is fixed on the drum; Be wound with suspender belt on the outer ring face of described drum; Also be provided with a ratchet in the described housing, described ratchet is rotatably connected on the housing, it is connected with spring between an end of run-on point and housing, the ratchet of this end and ratchet is slidingly connected under the effect of spring, its other end that is positioned at run-on point is the acute angle convex shape, ratchet by the ratchet high-speed impact under, described acute angle convex shape and hook tooth tabling.
The present invention has adopted the drum assembly of an integrative-structure, so that whole speed differs from more tending towards stability property of automatic controller, and can significantly reduce the volume of drum, thereby reduces the volume of the poor automatic controller of speed, more is convenient for carrying and work high above the ground.And can significantly prolong the service life that speed differs from automatic controller.

Fig. 2 is cutaway view of the present invention.
The specific embodiment
Embodiment
Below in conjunction with Fig. 1 and Fig. 2 the embodiment of the invention is described in further detail.
The drum of the poor automatic controller of a kind of speed, described drum 2 is structure as a whole; The rounded cavity-like 21 of one side of described drum 2, the opposite side of drum 2 is evenly distributed into four fan-shaped cavities 22 by two orthogonal reinforcements; Described any reinforcement is provided with a through wires hole that can supply suspender belt to pass; The center of described drum 2 offers an axis hole 23 that can supply central shaft to pass.
Use the poor automatic controller of speed of above-mentioned drum, comprise housing 1 and the drum 2 that is arranged in the housing 1, be provided with central shaft 8 in the described housing 1; Be socketed with drum 2, ratchet 7 on the described central shaft 8, drum 2 is fixedly connected with ratchet 7; Described drum 2 is structure as a whole, and is provided with clockwork spring 6 in the described drum 2, and an end of clockwork spring 6 and central shaft 8 are fixing, and the other end of clockwork spring 6 is fixed on the drum 2; Be wound with suspender belt 5 on the outer ring face of described drum 2; Also be provided with a ratchet 3 in the described housing 1, described ratchet 3 is rotatably connected on the housing 1, it is connected with spring 4 between an end of run-on point and housing 1, the ratchet of this end and ratchet 7 is slidingly connected under the effect of spring 4, its other end that is positioned at run-on point is the acute angle convex shape, ratchet 3 by ratchet 7 high-speed impacts under, described acute angle convex shape and hook tooth tabling.
Wherein optimal way is, described housing 1 is provided with reinforcement.
Wherein optimal way is, the end that described suspender belt 5 stretches out housing 1 is connected with drag hook 9.When at ordinary times work high above the ground is used, because power is less, suspender belt 5 drives drum 2 and rotates at central shaft 8, thereby central shaft 8 drives clockwork spring 6 and tightens up, and after the power disappearance that acts on the suspender belt 5, clockwork spring 6 loosens, begin retraction, clockwork spring 6 drives central shaft 8 backward rotation, and central shaft 8 drives drum 2 and rotates, and the suspender belt 5 of pulling out is reclaimed be wrapped on the drum 2.When being in an emergency, because human body tenesmus, can suddenly accelerate, within the extremely short time, produce a larger speed difference, thereby having a very large power acts on suddenly on the suspender belt 5, thereby suspender belt 5 drives drums 2 and rotates at central shaft 8, and the ratchet 7 on the drum 2 accelerates to rotate, acting on the ratchet 3 energetically, so that ratchet 3 significantly rotates, block stop so that an end claw of ratchet 3 matches with the gear of ratchet 7, immediately block ratchet 7, so that ratchet 7 stops operating, thereby allow drum 2 stop operating, suspender belt 5 no longer down stretches, and hangs the workmen, has reached purpose of the present invention.
