Description
本創作係一種防墜裝置之結構方面的技術領域,尤指一種具有較佳安全性及操作方便之防墜裝置改良結構者。The present invention relates to the technical field of the structure of the anti-drop device, and more particularly to an improved structure of the anti-drop device with better safety and convenient operation.
一般習知應用於高空作業之防墜裝置,如吾人早期申請之台灣公告第I349727號專利所示,其主要係於一軸件之左、右兩段分別沿軸向間隔設有對稱之複數棘齒,於該軸件上設有可供高空作業人員之安全繩吊掛之吊掛座,並於該軸件之左、右兩段上分別套設有可軸向移動之爪座,該爪座具有一活動夾及結合在該活動夾上之一控制件,該控制件具有單向卡齒,且其受彈簧之作用係使該單向卡齒平時與棘齒嚙合,使將該兩爪座沿著該軸件相向夾合時,該兩控制件之單向卡齒能順著推動方向順序進出棘齒,該兩爪座沿著該軸件反向移動時,該兩控制件之單向卡齒便會被棘齒擋住而無法移動,而是需要另外按壓該兩控制件使單向卡齒脫離棘齒,方可使該兩爪座沿著該軸件反向移動,因此便可達到單向夾合而不會任意張開之作用。藉此,使該兩夾座夾持在H型鋼上,便可使該防墜裝置沿著該H型鋼移動,進而提供與其連結之工作人員於橫樑或橫檐……等高空處行走時之安 全防護作用。A conventional anti-drop device for use in aerial work, as shown in the Taiwan Patent Application No. I349727, which was originally filed by the Japanese Patent Application No. I-349727, which is mainly characterized in that the left and right sections of a shaft member are axially spaced apart from each other to form a symmetrical complex ratchet. , the shaft member is provided with a hanging seat for hanging the safety rope of the upper-air working person, and the axially movable claw seat is respectively sleeved on the left and right sections of the shaft member, the claw seat Having a movable clip and a control member coupled to the movable clamp, the control member has a one-way latching tooth, and the spring is acted upon to engage the one-way latching tooth with the ratchet, so that the two claws are When the shaft members are facing each other, the one-way teeth of the two control members can sequentially enter and exit the ratchet teeth along the pushing direction. When the two claw seats move in the opposite direction along the shaft member, the two control members are unidirectional. The latches are blocked by the ratchet and cannot be moved. Instead, the two control members need to be pressed to release the one-way latches from the ratchets, so that the two claws can be moved in the opposite direction along the shaft member, thereby achieving One-way clamping without arbitrarily opening. Thereby, the two clamping seats are clamped on the H-shaped steel, so that the anti-drop device can be moved along the H-shaped steel, thereby providing the staff connected thereto with the safety when walking at a height such as a beam or a cross-beam... Full protection.
然而,該習知的防墜裝置只要單方向施力於該兩爪 座上之控制件,便會釋放該兩爪座而使其可沿著軸件向外移動,進而使該兩活動夾可脫離對該H型鋼樑或H型軌道的夾持。尤其是,該兩控制件平時係僅依靠彈簧之彈力使其處於讓單向卡齒與棘齒嚙合之狀態,因此該兩控制件便很容易發生不小心被按壓到而使單向卡齒脫離棘齒之情形,因此其之安全性不佳。特別是,其係應用於高空作業上,如此微小的安全漏洞一旦造成工安意外,通常會危及人身性命,不可輕忽。However, the conventional anti-drop device only applies the force to the two claws in one direction. The control member on the seat releases the two claw seats so as to be movable outward along the shaft member, so that the two movable clamps can be disengaged from the clamping of the H-shaped steel beam or the H-shaped rail. In particular, the two control members usually rely on the elastic force of the spring to make the one-way latch teeth and the ratchet teeth engage, so that the two control members are easily accidentally pressed to cause the one-way latch to be disengaged. The situation of ratcheting, so its safety is not good. In particular, it is used in high-altitude operations. Once such a small security hole causes an accident, it usually endangers personal life and cannot be ignored.
習知防墜裝置之控制件只要被單方向的按壓即能 釋放該軸件而使該爪座能任意軸向移動,因此係存在著安全性不佳之問題。The control device of the conventional anti-drop device can be pressed as long as it is pressed in one direction. The shaft member is released to allow the claw seat to move freely in the axial direction, so that there is a problem of poor safety.
