A main shaft supporting seat is arranged on the base on the left side of the anti-falling safety device fixing frame. The right side of a working shaft which is driven by an automatic speed regulation motor and is horizontally arranged on the main shaft supporting seat stretches out of the main shaft supporting seat, and a chuck is arranged on the working shaft. A tail puller is arranged on the base on the right side of the anti-falling safety device fixing frame. An electromagnetic sensor is arranged on the working shaft. The signal output end of the electromagnetic sensor is electrically connected with the signal input end of an automatic velocimetry. According to the utility model, the anti-falling safety device speed calibration test bed has the advantages of simple structure, fast and convenient installation and test, and labor saving, and can calibrate anti-falling safety devices of various models and specifications; the applicable speed calibration range can be from 0.5m/s to 2.0m/s; and the calibration test bed is used to periodically test a construction lifter and the like, which can improve the safety of the lifter, and has great significance to guarantee the safety of building construction.
Description
Technical field
The utility model relates to safety detection test apparatus field, especially relates to a kind of anti-falling safety device rate calibration testing table.
Background technology
State Council builds competent authorities for guaranteeing construction safety, to the safety management of construction lifting equipment, has all strengthened dynamics from Systematic and technological layer.As the building hoist to wire rope gearing, material elevator require to configure through the qualified anti-falling safety device of type approval test, and every use all will be used through demarcating qualified could continuation for 1 year.Though set up successive check through safety supervision at different levels department; strictly supervise and examine; the accident that reason causes but the building hoist of wire rope gearing, material elevator are restricted because breaking is of common occurrence; trace it to its cause; except manufacturer's rope broken protector imperfection; applying unit lacks maintaining, only with not repairing etc. outside reason; from management layer analysis; building hoist to wire rope gearing, the important safety of material elevator---anti-falling safety device is not regularly demarcated, and can't but be one of major reason.Although some manufacturer also demarcates the excitation apparatus of own product, be mostly only to demarcate transmission shaft or certain part of excitation apparatus, can not demarcate by complete machine.11.3.5 article of regulation in 2007 version state compulsory standard GB10055 " building hoist safety regulationss ": " should adopt the anti-falling safety device of speed flip-over type for the dual-purpose building hoist of people's goods of wire rope gearing ".But the speed flip-over type safety catcher of the building hoist of wire rope gearing (containing material elevator) configuration, does not have the special testing table (frame) of demarcating in China so far.
Summary of the invention
The utility model object is to provide a kind of anti-falling safety device rate calibration testing table that can demarcate anti-falling safety device complete machine.
For achieving the above object, the utility model can be taked following technical proposals:
Anti-falling safety device rate calibration testing table described in the utility model, comprise base, on described base, be provided with anti-falling safety device fixed mount, on the base in described anti-falling safety device fixed mount left side, be provided with main shaft support seat, extend outside main shaft support seat on the right side that is horizontally set on the working shaft on described main shaft support seat being driven by automatic speed regulating motor, is provided with chuck on it; On the base on described anti-falling safety device fixed mount right side, be provided with afterbody holding device; On described working shaft, be provided with electromagnetic sensor, the signal output part of described electromagnetic sensor is electrically connected with the signal input part of automatic speed-measuring instrument.
For adapting to the demarcation of anti-falling safety device of all size model, described anti-falling safety device fixed mount is made up of the saddle of bottom and the upper slide rest on top, on described base, be provided with cross slide way, described saddle is by the guide groove left and right transverse shifting matching with described cross slide way arranging on bottom surface; Be provided with longitudinal rail at described saddle upper surface, before and after the guide groove matching with described longitudinal rail that described upper slide rest arranges by bottom, vertically move.
Described afterbody holding device is the screw mandrel that holds out against being horizontally set in aft mount.
The utility model advantage is simple in structure, and installation testing is efficient and convenient and very laborsaving, can demarcate the anti-falling safety device of all size model, and the rate calibration scope of application can reach 0.5m/s-2.0 m/s.Be used in conjunction with automatic speed-measuring instrument, in the time that anti-falling safety device excitation apparatus moves, catch the instantaneous velocity signal that excites, the instantaneous velocity by automatic speed-measuring instrument automatic speed-measuring and when printing anti-falling safety device and exciting, and then anti-falling safety device is carried out to rate calibration.Adopt Calibrating experimental bench of the present utility model to carry out routine test to building hoist, material elevator, can avoid to greatest extent this class lifter in service because of the disconnected possibility of restricting and falling, but improve the security of this type of lifter, workmen and the safety of transporting material are ensured, to ensureing that construction safety is significant.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, anti-falling safety device rate calibration testing table described in the utility model, comprise base 1, on base 1, be provided with anti-falling safety device fixed mount 2, on the base in anti-falling safety device fixed mount 2 left sides, be provided with main shaft support seat 3, extend outside main shaft support seat on the right side that is horizontally set on the working shaft on main shaft support seat 3 being driven by automatic speed regulating motor, is provided with chuck 4 on it; On the base on anti-falling safety device fixed mount 2 right sides, be provided with afterbody holding device, afterbody holding device is to be horizontally set on to hold out against screw mandrel 8 in aft mount 7; On working shaft, be provided with electromagnetic sensor 5, the signal output part of electromagnetic sensor 5 is electrically connected with the signal input part of automatic speed-measuring instrument 6.
When work, anti-falling safety device to be calibrated 9 is placed on anti-falling safety device fixed mount 2, chuck 4 clamps the driving wheel (axle) of anti-falling safety device 9, hold out against screw mandrel 8 and hold out against anti-falling safety device 9 from rear portion, automatic speed regulating motor drives the driving wheel (axle) of working shaft and chuck 4 and anti-falling safety device 9 to be calibrated to rotate by belt pulley and V-belt, by normal running speed with 0.01 m/s
