Description
本創作係與防墜器有關;特別是指一種適用於高空作業場所的防墜器。This creation is related to the fall arrester; in particular, it is a fall arrester suitable for use in high-altitude work places.
一般在屋頂、工廠、電梯維修、造船、航太基地、建築工地等高空作業場所中,多半會籲請人員在作業時,配備防墜器(止墜器)等***品,該防墜器係供連接有一救生帶搭配使用,而該救生帶的一端係繫在工作人員的身上,藉此,當工作人員不慎從高空墜落時,其防墜器可對該救生帶作緊急鎖止或緩衝的動作,藉以防止人員繼續墜落或用來緩衝人員的墜落速度,進而確保工作人員的人身安全。Generally, in high-altitude work sites such as roofs, factories, elevator repairs, shipbuilding, aerospace bases, and construction sites, most people are urged to equip their work with safety parts such as fall arresters (fall arresters). A lifebelt is connected and used, and one end of the lifebelt is attached to the worker's body, so that when the worker accidentally falls from a high altitude, the fall arrester can urgently lock or cushion the lifebelt. Actions to prevent personnel from continuing to fall or to buffer the speed of the person's fall, thus ensuring the personal safety of the staff.
目前市面可見的防墜器主要有以下幾種態樣,舉例來說,有一種設計係在防墜器之救生帶的結構上作可彈性拉伸的設計,藉此,當繫有救生帶之人員墜落時,其可彈性拉伸的救生帶可用來緩衝、減緩人員的墜落速度。然而,這樣的設計須考慮到救生帶的長度、彈性拉伸係數、所配合之高空作業的高度以及人員體重等因素,且假使作業高度與救生帶的理想作用長度配合不佳時,很有可能的是,救生帶回彈不及而人員卻已墜落至地面,而有所缺失。At present, the anti-dropping devices visible in the market mainly have the following aspects. For example, there is a design that is elastically stretchable on the structure of the life-saving belt of the fall arrester, thereby having a lifebelt. When the person falls, the elastically stretchable lifebelt can be used to cushion and slow down the person's fall speed. However, such a design must take into account factors such as the length of the lifebelt, the elastic stretch factor, the height of the aerial work to be matched, and the weight of the person, and it is highly probable that if the working height does not match the ideal length of the lifebelt. The life belt has rebounded and the personnel have fallen to the ground and are missing.
另外,有一種防墜器的設計在於,其救生帶的其中一段係作交疊地縫合,藉此,當人員墜落時,其救生帶交疊縫合的部位將因受力而被扯開,藉以吸收人員部分的墜落能量,來達到緩衝的效果。惟這樣的設計對救生帶會產生結構上的破壞,以至於救生帶的強度、承載力下降,而有危險之虞。In addition, there is a fall arrester designed such that one of the life belts is stitched in an overlapping manner, whereby when the person falls, the portion of the life belt overlapping and stitching is torn apart by the force, thereby Absorb the energy of the part of the person to achieve the cushioning effect. However, such a design would cause structural damage to the lifebelt, so that the strength and bearing capacity of the lifebelt decreased, and there was a danger.
除此之外,另有一種防墜器係採取快速鎖止的方式,亦即,當人員墜落而產生瞬間的拉力時,防墜器將緊急鎖止其救生帶以使救生帶不續落,其中,這樣的設計雖然可達到立即阻止人員墜落的效果,然而在其緊急停止的瞬間所產生的瞬間衝擊力(如G-Force)與反作用力,將可能導致人員得內傷甚至是有骨骼斷裂的意外情況發生,而有尚待改進之處。In addition, another type of fall arrester adopts a quick lock mode, that is, when a person falls and generates an instantaneous pulling force, the fall arrester will urgently lock the life belt so that the life belt does not continue to fall. Among them, although such a design can achieve the effect of immediately preventing the person from falling, the instantaneous impact force (such as G-Force) and reaction force generated at the moment of emergency stop may cause internal injuries or even bone fracture. Unexpected circumstances occur and there are areas for improvement.
有鑑於此,本創作之目的在於提供一種防墜器,藉以避免人員從高空高速墜落。In view of this, the purpose of this creation is to provide a fall arrester to avoid people falling from high altitude.

The frame has an accommodating space; the shaft is disposed on the frame; the speed reducing member is rotatably pivoted on the shaft and located in the accommodating space, the speed reducing member has a friction surface; The rotating sleeve is sleeved on the speed reducing member and has an outer annular surface and an inner annular surface, wherein the outer annular surface is wound by the lifebelt, and the inner annular surface is matched with the friction surface of the speed reducing member; In a first operating state, the speed reducing member rotates coaxially with the rotating drum; in a second operating state, the speed reducing member is fixed and the rotating drum is rotatable relative to the speed reducing member, and the friction surface of the speed reducing member A rotational friction is generated between the inner annulus of the drum to slow the rotation of the drum, thereby buffering the speed at which the life belt descends.
本創作之效果在於,透過該減速件之摩擦面與轉鼓之內環面的配合設計,於工作人員在一般正常的第一操作狀態下,減速件並不會影響轉鼓的轉動;而當工作人員不甚從高空墜落時,則進入第二操作狀態,此時,減速件與轉鼓之間將產生轉動摩擦力,以減緩轉鼓的轉速,進而達到緩衝救生帶下降速度或限制救生帶下降速度的效果。The effect of the creation is that, through the cooperation design of the friction surface of the speed reducer and the inner ring surface of the drum, the speed reducer does not affect the rotation of the drum when the worker is in the normal normal first operation state; When the staff does not fall from high altitude, they enter the second operating state.

藉此,透過上述結構設計,於工作人員處在穩定、未發生有急劇墜落的使用情境下,例如,人員正常地在如一工作平台、棧板上行走時,於此定義為處於一第一操作狀態下,該制動組件60係保持於內縮定位之勢,且未與架體10上之第一擋止部125相接觸,此時,該轉盤50以及該減速件30係與該轉鼓40以及該側蓋70同軸轉動(或可同步轉動),且當救生帶200被拉伸時,例如:繫有救生帶200的工作人員遠離該防墜器100而使得救生帶200被拉伸時,由於該渦捲彈簧80的一端84係固定於該側蓋70上,因此,渦捲彈簧80將隨著救生帶200被拉伸而拉伸,因而可隨之蓄積有一捲收成卷的回復力(或稱彈力);另外,當工作人員接近防墜器100時,拉伸救生帶200的力將減弱而小於渦捲彈簧80的彈力,此時,渦捲彈簧80便會產生彈性回復而收納成捲,進而帶動救生帶200一併再度捲繞收回轉鼓40上。Thereby, through the above structural design, in the use situation where the staff is stable and there is no sharp fall, for example, when the person normally walks on a working platform or a pallet, it is defined as being in a first operation. In this state, the brake assembly 60 is maintained in the position of the retracted positioning, and is not in contact with the first stopping portion 125 on the frame body 10. At this time, the rotating plate 50 and the speed reducing member 30 are coupled to the rotating drum 40. And the side cover 70 is coaxially rotated (or can be rotated synchronously), and when the lifebelt 200 is stretched, for example, when the worker with the lifebelt 200 is away from the fall arrester 100 and the lifebelt 200 is stretched, Since one end 84 of the scroll spring 80 is fixed to the side cover 70, the scroll spring 80 is stretched as the lifebelt 200 is stretched, so that a recovery force of a roll of the roll can be accumulated ( In addition, when the worker approaches the fall arrester 100, the force of the stretched lifebelt 200 will be weakened and less than the elastic force of the scroll spring 80. At this time, the scroll spring 80 will elastically recover and be stored. Roll, and then drive the lifebelt 200 together and rewind The rotary drum 40.
而於另一使用情境下,於救生帶200突然地被瞬間拉伸時,例如:繫有救生帶200之人員不慎從高空墜落時,救生帶200將被急劇地拉伸,於此定義為一第二操作狀態下,請配合圖3至圖5所示,該制動塊62將受一力矩作用或受一離心力作用而克服復位彈簧64的彈力,並以樞柱521為支點向外甩出,而使得制動塊62的一第一部位621抵靠於托架12之第一擋止部125,且使得制動塊62的一第二部位622抵靠於定位塊54的一第二擋止部541,屆時,該轉盤50將受制動組件60與托架12相卡合的影響而固定不動,且與轉盤50相固接的減速件30亦固定而不轉動。於後,轉鼓40因受救生帶200的拉伸影響將持續轉動,而由轉鼓40之內環面440係與固定不動之減速件30的摩擦面31相配合的關係,於轉鼓40相對於該減速件30轉動時,減速件30的摩擦面31將與轉鼓40之內環面440產生轉動摩擦力,藉此便可減緩或限制轉鼓40的轉速,進而達到緩衝救生帶被拉伸而下降的速度與所繫之人員的墜落速度之目的。In another use case, when the lifebelt 200 is suddenly stretched instantaneously, for example, when a person with the lifebelt 200 inadvertently falls from a high altitude, the lifebelt 200 will be sharply stretched, which is defined as In a second operating state, as shown in FIG. 3 to FIG. 5, the brake block 62 is subjected to a moment or subjected to a centrifugal force to overcome the elastic force of the return spring 64, and is pivoted outwardly with the pivot post 521 as a fulcrum. a first portion 621 of the brake block 62 abuts against the first stop portion 125 of the bracket 12, and a second portion 622 of the brake block 62 abuts against a second stop portion of the positioning block 54 541. At this time, the turntable 50 is fixed by the engagement of the brake assembly 60 and the bracket 12, and the speed reducer 30 fixed to the turntable 50 is also fixed without rotating. Thereafter, the rotating drum 40 is continuously rotated by the tensile force of the lifebelt 200, and the inner ring surface 440 of the rotating drum 40 is coupled with the friction surface 31 of the fixed speed reducing member 30, and is coupled to the rotating drum 40. When rotating relative to the speed reducer 30, the friction surface 31 of the speed reducer 30 will generate rotational friction with the inner ring surface 440 of the drum 40, thereby slowing or limiting the rotational speed of the drum 40, thereby achieving a cushioned lifebelt. The purpose of stretching and descending speed and the falling speed of the person being tied.
其中,為達理想的防墜器緩衝、減速效果,該轉鼓40之內環面440與減速件30之摩擦面31之間的配合公差係設計在介於0mm至0.3mm之間,或者稱其配合公差係介於30條以內,或稱內環面440與摩擦面31之間最短距離的絕對值介於0mm至0.3mm之間。其中,前述的配合公差的數值選用,係可依據承載力、使用之人員的體重需求任意選擇。In order to achieve the ideal anti-drop device buffering and deceleration effect, the tolerance between the inner ring surface 440 of the rotating drum 40 and the friction surface 31 of the speed reducing member 30 is designed to be between 0 mm and 0.3 mm, or The tolerance is less than 30, or the absolute distance between the inner ring 440 and the friction surface 31 is between 0 mm and 0.3 mm. Among them, the above-mentioned selection of the tolerance value can be arbitrarily selected according to the bearing capacity and the weight requirement of the person using the same.
另外,於一實施例當中該轉鼓的內環面440與減速件的摩擦面之間係可依據使用上之需求或依據製作防墜器之材料特性等因素,選擇性地採留隙配合(Clearance Fit)、過渡配合(Transition Fit)或過盈配合(Interference Fit)之緊配合設計。In addition, in an embodiment, the inner annular surface 440 of the rotating drum and the friction surface of the speed reducing member can be selectively matched according to the use requirements or the material properties of the fall arrester. Clearance Fit), Transition Fit or Interference Fit.
值得一提的是,前述設計有該些間隔凸起742的優點在於,除可使得側蓋70在保有足夠的結構強度下達到輕量化的效果外,其凸起742之間的縫隙亦可留存不慎侵入側蓋內部的異物,而不影響其內部渦捲彈簧之拉伸與收捲的作動。It is worth mentioning that the above-mentioned design has the spacer protrusions 742, which has the advantage that the gap between the protrusions 742 can be retained in addition to the side cover 70 achieving the weight reduction effect while maintaining sufficient structural strength. Inadvertently invade the foreign matter inside the side cover without affecting the stretching and winding of the internal scroll spring.
另外一提的是,於其他實施上,亦可僅設置一組、三組或三組以上的制動組件60而不以兩組制動組件60為限制。In addition, in other implementations, only one, three or more sets of brake assemblies 60 may be provided instead of the two sets of brake assemblies 60.
