Description
Technical field
The present invention relates to a kind of fastening devices of Working pedal, is a kind of Working pedal two ends that are fixed on specifically, is used for Working pedal fixing device that Working pedal is fixedlyed connected with the steel pipe of pedal erecting bed reliably.
Background technology
Usually the places such as building, building, shipbuilding that need manpower to carry out work high above the ground often need have passage and Working pedal with scaffold for the staff provides.The structure of routine work pedal is as follows: have dimetric brandreth and gauze wire cloth or monolithic porous fixed thereon, the two ends of brandreth are connected with hook by welding or nut, fasten by the steel pipe of hook, Working pedal is fixed on the pedal erecting bed of scaffold with the pedal erecting bed of scaffold.This hook is because the needs of installing are generally down " U " shape, though Working pedal and pedal erecting bed can be connected and fixed easily and dismantle,, impact etc. as strong wind or in working exists potential safety hazards such as Working pedal is blown off or hits.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of Working pedal fixing device is provided, overcome existing Working pedal be connected with the pedal erecting bed unreliable, exist the deficiency that Working pedal is blown off by strong wind or potential safety hazard such as hits, Working pedal fixing device of the present invention can firmly be fastened on the pedal erecting bed Working pedal is convenient.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Working pedal fixing device, hook with the brandreth two ends that are fixed on Working pedal, hook root side is provided with the arc locking plate, offer guide-localization groove and following guide-localization groove on the arc locking plate, be equipped with the shouldered lead of head respectively in last guide-localization groove and the following guide-localization groove, lead is fixedlyed connected with hook.Four Working pedal fixing devices of the present invention are fixed on the side at Working pedal brandreth two ends by welding or nut, during the installation work pedal, arc locking plate lower end contacts with the steel pipe of pedal erecting bed, be subjected to the frictional force effect, the arc locking plate is that fulcrum upwards slides with two leads, after the hook of Working pedal fixing device is buckled on the steel pipe, the arc locking plate is subjected to impact force and the self gravitation double action in the installation process, the arc locking plate is the fulcrum natural downslide with the lead, the intrados of arc locking plate is fastened under the steel pipe half side, Working pedal is locked in securely on the steel pipe of pedal erecting bed.During dismounting, the arc locking plate is pushed away on gently, Working pedal can be unloaded like a cork.
Be the Working pedal easy installation and removal, the arc locking plate can be with the steel pipe positive lock of Working pedal and pedal erecting bed, the last guide-localization groove middle part of aforesaid arc locking plate is a upper hopper chute, the center of the first half circular arc trough rim at last guide-localization groove two ends is offset to the right with respect to the upper hopper chute center line, the middle part is a gliding groove on the described guide-localization groove down, the center of the semicircle trough rim of following guide-localization groove lower end is offset left with respect to the gliding groove center line, and the trough rim rounding off of semicircle trough rim and gliding groove is connected.When the lead in the following guide-localization groove of the arc locking plate of Working pedal fixing device is positioned at the upper end, the lead that last guiding is decided in the La groove also is in the upper end, because action of gravity, the half-arc groove edge joint of lead and last guide-localization groove upper end touches, as arc locking plate lower end upwards not being pushed away, then the arc locking plate is fastened under the steel pipe half side securely; When the lead in the following guide-localization groove of the arc locking plate of Working pedal fixing device is positioned at the lower end, the lead that last guiding is decided in the La groove also is in the bottom, because action of gravity, the half-arc groove edge joint of lead and last guide-localization groove lower end touches, under impact force in being subjected to installation process and the self gravitation double action, the arc locking plate is the fulcrum natural downslide with the lead, and the intrados of arc locking plate is fastened under the steel pipe half side.
The invention has the beneficial effects as follows, Working pedal fixing device of the present invention, simple in structure, easy to use, can be with the steel pipe positive lock of Working pedal and pedal erecting bed, avoid Working pedal to be blown off or hit by strong wind.
