Abstract
The utility model relates to a special overturning support for hoisting and overturning a large-size memorial archway. The special overturning support for hoisting and overturning the large-size memorial archway comprises a slippage rack, an overturning arm, a pressure-bearing base plate and a memorial archway hinging lug plate, wherein one end of the overturning arm is hinged on the slippage rack through a pin shaft; the memorial archway hinging lug plate is vertically and fixedly arranged on the overturning arm; and the pressure-bearing base plate is fixedly arranged on the overturning arm on one side of the memorial archway hinging lug plate. The special overturning support for hoisting and overturning the large-size memorial archway is simple in structure, scientific and reasonable in design and simple to produce; and besides, transition of the hoisting system is prevented, the memorial archway can be safely and stably overturned, and accidents are avoided.
Description
Technical field
The utility model belongs to the turning supporting seat field, especially a kind of special overturn bearing for large-scale memorial archway lifting upset.
Background technology
In recent years, in the installation process of large-scale memorial archway, all relate to the memorial archway upset, if adopt crane slide tail to realize the memorial archway upset, then need large tonnage crane configuration and higher expense.Be cost saving, many large-scale memorial archways mostly adopt memorial archway tail end touchdown point place as turning over hinge-point when the lifting upset, realize upset with the mode that promotes in conjunction with tail end slippage follow-up.But, in use find, in the lifting switching process, when the memorial archway line of gravity meets or exceeds when turning over hinge-point, whole lifting system can unexpected generation transition out of control, and acutely rocking appears in memorial archway, load bearing system is subjected to very big impact load, and hoisting structure system moment is in dangerous situation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of special overturn bearing for large-scale memorial archway lifting upset is provided, this turning supporting seat is simple in structure, design science reasonable, it is simple to make, prevent the Lift-on/Lift-off System transition, the memorial archway upset is realized on safety and steady ground, avoids occurring safety misadventure.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of special overturn bearing for large-scale memorial archway lifting upset, its special overturn bearing comprises slippage frame, flip-arm, pressure-bearing backing plate and memorial archway hinge dress otic placode, flip-arm one end is contained in above the slippage frame by the bearing pin hinge, memorial archway hinge dress otic placode vertically be packed in flip-arm above, on the flip-arm of memorial archway hinge dress otic placode one side, install a pressure-bearing backing plate.
And described pressure-bearing backing plate is packed in above the flip-arm of flip-arm hinge dress end one side and close memorial archway hinge dress otic placode.
Advantage of the present utility model and beneficial effect are:
This special overturn bearing that is used for large-scale memorial archway lifting upset adopts slippage frame and flip-arm, the hinged formation lower link point of one end of described flip-arm and slippage frame, the other end of flip-arm utilizes the hinged formation upper link point of tail end of memorial archway hinge dress otic placode and memorial archway, when memorial archway overturns, at first, when promoting the memorial archway front end, cooperate memorial archway tail end slippage follow-up synchronously, memorial archway is under the hoisting force effect, and around the upper link point upset, upper link point was and turned over hinge-point this moment; When memorial archway tail end contact flip-arm, continue to promote the memorial archway front end, turn over hinge-point and can transfer to the lower link point of flip-arm automatically, after this lifting is in conjunction with slippage, can realize the memorial archway upset, vertical until memorial archway, when turning over after hinge-point transfers to the lower link point of flip-arm, the line of gravity of memorial archway can not surpass the upset hinge all the time, therefore transition can not take place, make the memorial archway lifting be in safe controllable state all the time, after upset is finished memorial archway load is all transferred on the lifting suspension centre, i.e. being articulated and connected between the tail end of the other end of dismountable described flip-arm and memorial archway, thereby finish rotary movement, this turning supporting seat can prevent the Lift-on/Lift-off System transition, and the memorial archway upset is realized on safety and steady ground, avoids occurring safety misadventure.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of special overturn bearing for large-scale memorial archway lifting upset, its special overturn bearing comprises slippage frame 3, flip-arm 5, pressure-bearing backing plate 2 and memorial archway hinge dress otic placode 1, flip-arm one end is contained in above the slippage frame by bearing pin 4 hinges, memorial archway hinge dress otic placode vertically be packed in flip-arm above, install a pressure-bearing backing plate on memorial archway cuts with scissors the flip-arm of adorning otic placode one side, the pressure-bearing backing plate is packed in above the flip-arm of the also close memorial archway hinge of flip-arm hinge dress end one side dress otic placode furtherly.
The utility model in use, adorn by the bearing pin hinge with memorial archway hinge dress otic placode below memorial archway 6 rear ends, when promoting the front end of memorial archway, cooperate the tail end slippage follow-up of memorial archway synchronously, memorial archway is under the hoisting force effect, be the upset of memorial archway hinge dress otic placode hinge dress end around upper link point, memorial archway hinge dress otic placode hinge dress end was and turned over hinge-point this moment; When memorial archway tail end contact flip-arm, continue to promote the memorial archway front end, turn over hinge-point and can transfer to the hinge dress end of flip-arm and slippage frame automatically, after this memorial archway promotes and moves in conjunction with slippage, can realize the upset of memorial archway, vertical until memorial archway, transfer to the hinge dress end of flip-arm and slippage frame when turning over hinge-point, the line of gravity of memorial archway can not surpass the upset hinge all the time, therefore transition can not take place, make the memorial archway lifting be in safe controllable state all the time, after upset is finished memorial archway load is all transferred on the lifting suspension centre, be that dismountable memorial archway cuts with scissors being articulated and connected between the tail end of adorning otic placode and memorial archway, thereby finish rotary movement.
