Abstract
The utility model discloses an insidelink type liftable guardrail, which comprises a working platform, wherein the two sides of the working platform are respectively provided with a lifting rod, the top of the lifting rod is provided with a guardrail, a limit block is arranged on the guardrail and is provided with a rotary base, an insidelink sleeve is hinged in the rotary base, an insidelink is arranged in the insidelink sleeve, the end head of the insidelink is provided with a fastener, and a safety base which is used for fastening the insidelink fastener is arranged on the working platform. When an accident is occurred, the human body is moved backwards to the guardrail, and the insidelink connected the guardrail and the safety base is tensioned, effective reverse acting force on the contact position of the human body can be directly provided, so that insidelink type liftable guardrail plays a real protective action.
Description
Technical field
The utility model relates to the high-altitude operation platform field, in particular for the high-altitude operation platform of operation at top vehicle, is specially a kind of interior pull-type liftable guardrail.
Background technology
The roof operated by rotary motion of operation at top vehicle has high-altitude operation platform, uses during for aloft work.Traditional liftable guardrail can only provide antagonistic force in lifting bar (or claim " vertical rod " etc.) bottom, and at the time of emergency, lifting bar height high torque more is big more, makes lifting bar distortion even fracture easily, thereby loses due protective action.
The utility model content
The purpose of this utility model provides a kind of interior pull-type liftable guardrail, to solve the big more easy fracture more of liftable guardrail height of prior art, the problem of poor stability.
In order to achieve the above object, the technical scheme that the utility model adopted is:
Pull-type liftable guardrail in a kind of, include workplatform, described workplatform both sides are separately installed with lifting bar, the top of homonymy lifting bar is equipped with guardrail, it is characterized in that: be equipped with many on the described guardrail double-type limiting stopper, rotary seat is installed between the limiting stopper, described rotary seat can be along the guardrail rotational, be hinged with the draw-in bar cover in the described rotary seat, be rotatablely equipped with telescopic draw-in bar in the draw-in bar cover, described draw-in bar end is provided with buckle, also is provided with the emergency seat of a plurality of bracelet eyes on the described workplatform, and the buckle of described draw-in bar termination can snap in the buttonhole of emergency seat.
Described a kind of interior pull-type liftable guardrail, it is characterized in that: also screwed togather a plurality of vertical screw rods on the described guardrail, screwed togather nut on the vertical screw rod, the buckle of described draw-in bar termination can be connected on the vertical screw rod, and the nut that is screwed on the vertical screw rod is fixed.
The utility model is installed the rotatable rotary seat on guardrail, hinged draw-in bar cover in the rotary seat, and emergency seat is installed on workplatform, guardrail fastens emergency seat with draw-in bar and gets final product after rising.After guardrail was fallen, the buckle of draw-in bar can be connected on the vertical screw rod, was fixed on guardrail below (can be adjusted into as required and be installed in other directions of guardrail).The operating personnel should fasten emergency seat to two draw-in bars of major general; For long guardrail, the draw-in bar at middle part must fasten emergency seat.The utility model human body is at the time of emergency swung to guardrail, connects the draw-in bar tension of guardrail and emergency seat, directly provides the actv. antagonistic force at human body and guardrail contact position, thereby plays practical protective action.
