in technique scheme, overall structure is simply firm, good integrity, security of operation stability and high efficiency, during operation, directly over the step bearing that top is placed in handrail elevator, and just to the position of step BEARING SHAFT, and the support block of two bearing devices to be placed in below accessory whorl and to be positioned at the position of bearing periphery, then down maneuver on lifting screw master arm is made by manipulation device, withstand the axle center on step bearing top, and control master arm, the continuation down maneuver of force fit lifting screw is upwards applied by artificial or machinery, support block so just can be made to be lifted by accessory whorl and depart from step bearing, total and course of action make accessory whorl stressed more even, also less to its damage, and it is stable, distortion can not be caused to step tripod, efficiency is high, the active force applied is little, operation easier is low, cost of labor reduces, effective accessory whorl in enormous quantities can be continued and remove operation.
as to preferably of the present utility model, manipulation device comprises the transverse direction that the manipulation socket cap is connected with the top one of lifting screw, described manipulation socket cap are offered and runs through the operation hole of described manipulation socket cap and pass the control stick that described operation hole is provided with.Be convenient to handle, rotated the lift work that can complete lifting screw by the lever in the horizontal plane of control stick.
as to preferably of the present utility model, fixed block to be set on master arm and to be installed by the clamping screw that above-below direction is arranged fixing with on described master arm.Sheathed mode is convenient to can effectively regulate when not being locked by clamping screw, and the step accessory whorl meeting different size and requirement removes the requirement of operation, uses more flexible.
as to preferably of the present utility model, master arm is positioned at the upper surface place at the position at screwhole position place and lower surface place is connected with reinforcing sleeve and lower reinforcing sleeve respectively, is also equipped with the screw passed through for lifting screw in described upper reinforcing sleeve and lower reinforcing sleeve.Improve structural strength, and ensure stability and the dismounting effect of removing operation.
as to preferably of the present utility model, come directly towards the taper type in causing.Optimize distribution of force, improve the stability and dismounting effect of removing operation.
as to preferably of the present utility model, the support block of two bearing devices in left and right is the fan ring-shaped of specular and can be combined into a complete circle shape and its internal diameter size is greater than the outside dimension of step bearing.Optimize distribution of force, improve the stability of removing operation and remove effect, also ensure that support block is positioned at the periphery of bearing to such an extent as to support block can not be caused to withstand bearing bottom and cannot operation simultaneously.
the beneficial effects of the utility model: overall structure is simply firm, good integrity, security of operation stability and high efficiency, remove effective, distribution of force is more excellent, and interstructural damage reduces, and can not cause distortion, cause damage etc. to accessory whorl step tripod, efficiency is high, the active force applied is little, operation easier is low, and cost of labor reduces, and can continue effective accessory whorl in enormous quantities and remove operation, easy to operate, use flexibly.
