Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the process of dismantling objects on the surface of a cylindrical high building, the mode of erecting scaffolds at different horizontal heights is often adopted, or the lifting structure is adopted to lift the scaffolds to the calibrated dismantling position, but the two modes have the problems of complex equipment and high cost, and are especially dismantled on site in places with dense crowds, and the normal production activities of the crowds are influenced due to the fact that the engineering quantity is large, the public land is occupied for a long time.
Example 1:
as shown in fig. 1, the main object of the present invention is to provide an attached lifting scaffold for high altitude demolition, the working platform of which can be lifted to the demolition level designated by the demolition member like the suction cup of a partridge tiger and achieve the suction between the outer wall of the demolition member at the current level. The device changes the adsorption into the pressing covering of the peripheral limiting inflatable airbag on the outer wall of the demolition member, so that the working platform can be firmly fixed at a certain height of the demolition member, after the demolition operation at one height is completed, the inflatable airbag is deflated, and the working platform can be lifted to the demolition station at the next height after the pressure is relieved.
Specifically, as shown in fig. 1 to 7, the attached lifting scaffold comprises a locking device 1 fixedly installed at the top end of a demolition member 2, and a lifting platform device 4 which surrounds the demolition member 2 for one circle and can be lifted to a demolition station with a specified height of the demolition member 2 is installed below the upper locking device 1 through a driving device 3. The locking device 1 can provide a bearing structure for the lifting platform device 4.
The lifting platform device 4 comprises a fixed working platform 401, an air bag pressing device 402 which can press the side wall of the demolition member 2 when being inflated is arranged below the fixed working platform 401 and is used for realizing the locking of the lifting platform device 4 at the appointed height of the demolition member 2, the locking mode is that the air bag pressing device 402 and the side wall of the demolition member 2 form huge pressure after being inflated, and the pressure is increased because the friction force between objects is in direct proportion to the pressure exerted on the objects, and the friction force is increased along with the pressure. So that the work platform 401 can be kept stable at a certain height. And a guide device 5 for providing a lifting guide function for the lifting platform device 4 is arranged between the top end and the bottom end of the dismounting piece 2, so that the phenomenon that the lifting platform device 4 swings in the descending process due to strong high-altitude wind power is avoided.
The common scaffold needs to be fixedly connected with the side wall of the dismounting part 2 with a certain height, time and labor are wasted, the air bag pressure applying device 402 of the attached lifting scaffold does not need to build a plurality of movable scaffolds, and positioning and locking are achieved ingeniously by means of air bag pressing force, so that the structure is simple, and the operation is convenient. Specifically, the method comprises the following steps:
the airbag pressing device 402 comprises a plurality of airbag pressing assemblies 403 which are arranged below the fixed working platform 401 and surround the circumferential wall of the dismounting member 2, and two adjacent airbag pressing assemblies 403 are loosely connected through a locking member 407. Only after the airbag pressing assembly 403 is inflated and expanded, the locking members 407 can be tightened, so that the external support of the airbag pressing assemblies 403 is realized. The combination of the plurality of airbag pressing assemblies 403 is advantageous to the independent adjustment of the airbag pressing assemblies 403 to the side wall support of the demolition member 2 in a certain direction, so that the precision of angle adjustment is improved, and the working platform 401 is kept stable.
Meanwhile, the airbag pressing assemblies 403 each include a friction plate 404 and a limiting plate 405 which are oppositely arranged, preferably, the friction plate 404 and the limiting plate 405 are hinged below the working platform 401, and a punching airbag 406 which can be inflated towards the inside through an inflation device is arranged between the friction plate 404 and the limiting plate 405. The inner side of the limit plate 405 is provided with a limit groove 408 for accommodating the punching air bag 406, and the punching air bag 406 is fixedly arranged on the inner side groove wall of the limit groove 408.
In the process of dismantling the object on the surface of the high-altitude cylindrical building, the common surface is subjected to diameter change, so that inconvenience is brought to the lifting of the lifting platform device 4, the lifting platform device 4 is easy to collide with the surface of the dismantling part 2, or the motion track of the lifting platform device 4 needs to be laid in advance, and the engineering quantity is huge. When the ram air bag 406 is deflated, an adjustment distance 410 remains between the friction plate 404 and the demolition element 2. The advantage of the ram air bag 406 is that the gap between the lifting platform device 4 and the removing element 2 can be filled up according to the amount of inflation, which enhances the applicability of the device.
In order to prevent the collision between the friction plate 404 and the demolition member 2 after deflation of the ram air bag 406, the lifting of the lifting platform arrangement 4 is made more difficult. A reset piece 409 for enabling the friction plate 404 to be automatically close to the inner surface of the limit plate 405 when the ram air bag 406 is deflated is further arranged between the limit plate 405 and the friction plate 404. The return member 409 is preferably a compression spring.
The friction plate 404 is arranged on the outer surface of the demolition element 2, and the friction plate 404 prevents direct contact between the ram air bag 406 and the side wall of the demolition element 2, and prevents wear of the surface of the ram air bag 406 due to friction. The surface of the friction plate 404 is preferably provided with raised points that increase friction.
The retaining member 407 is disposed between two adjacent retaining plates 405. The retaining member 407 is primarily intended to provide lateral pressure to the retainer plate 405 located on the outer sidewall of the inflated ram air bag 406. So that the ram air bag 406 can transmit pressure to the inside of the friction plate 404 after being expanded. However, since the plurality of airbag compression assemblies 403 are temporarily assembled, the locking member 407 is improved in a conventional manner in view of the convenience of disassembly and assembly and the convenience of subsequent measurement of the pressure on one side of the airbag compression assemblies 403.
To facilitate the connection between the plurality of retaining members 407. The outer sides of the limiting plates 405 are provided with clamping rings 412, and the clamping rings 412 are arranged in the middle of the outer side walls of the limiting plates 405 so as to stably limit the two sides of the limiting plates 405. The locking member 407 comprises a plurality of fixed connecting blocks 413 arranged inside the clamping ring 412, the connecting blocks 413 have larger supporting surfaces and can provide stable pressure with larger area, and a movable chain 414 is detachably connected between every two adjacent fixed connecting blocks 413. The movable chain 414 is characterized in that the movable connection between two adjacent limiting plates 405 can be realized, and the movable chain has enough pulling strength when being pulled.
In order to simplify the equipment and reduce the dismantling operation cost, the locking device 1 comprises a splicing steel ring 102 arranged along the circumference of the upper end of the dismantling piece 2, and the splicing steel ring 102 is of an arc-shaped structure and is suitable for top installation of dismantling pieces 2 with different diameters.
A plurality of steel foot rests 101 are equidistantly arranged around the splicing steel ring 102. The driving device 3 comprises a fixed pulley 301 arranged on the steel foot frame 101, a plurality of winding rollers 302 which correspond to the fixed pulley 301 and are wound by a power device are arranged on the fixed working platform 401, and the fixed pulley 301 and the winding rollers 302 are connected through a steel wire rope 303. The wire winding roller 302 is driven to rotate by a power unit, and the wire rope 303 is wound around the wire winding roller 302 or the surface of the wire winding roller 302 is unwound. The lifting operation of the fixed working platform 401 is conveniently and rapidly realized.
How to realize guiding lifting in high altitude by the scaffold for dismantling high altitude operation and keep the stability of the structure is always a terminal problem to be overcome. The attached lifting scaffold is thus equipped with guiding means 5, in particular:
the guide device 5 comprises an upper clamping device 501 and a lower clamping device 502 which are respectively arranged at the top end and the bottom end of the demolition member 2 and correspond up and down, a guide steel cable 503 is arranged between the upper clamping device 501 and the lower clamping device 502, an adjusting wire roller 504 wound with the guide steel cable 503 is arranged on the lower clamping device 502, and a roller shaft of the adjusting wire roller 504 is connected with a servo motor 505 for driving the adjusting wire roller 504 to receive and release the guide steel cable 503. A guide groove 507 for the guide steel cable 503 to pass through is arranged at a corresponding position on the lifting platform device 4, and a guide wheel 508 for limiting the guide steel cable 503 is arranged close to the guide groove 507. The servo motor 505 drives the guide wire 503 to wind on the surface of the adjusting roller 504, so that the guide wire 503 is in a tight state between the upper clamping device 501 and the lower clamping device 502. And the guide steel cable 503 is movably connected on the motion track of the lifting platform device 4 through the guide groove 507, so that the lifting platform device 4 can be guided to lift along the guide steel cable 503.
For further precise guidance of the lifting platform arrangement 4 by the guide arrangement 5. The guiding device 5 further includes a first controller and a wire rope tension meter 506 electrically connected to the first controller, two ends of the wire rope tension meter 506 are fixedly connected to the guiding steel rope 503 below the upper clamping device 501, and the first controller is electrically connected to the servo motor 505. The plurality of wire rope tension meters 506 monitor tension applied to each guide wire rope 503, transmit tension data to the first controller, and the first controller processes the data and instructs the servo motor 505 to drive the wire adjusting roller 504 to work, so that the plurality of guide wire ropes 503 are all adjusted to the same preset tension value. At the level of the secondary tension, the stiffness of the guiding wire 503 is sufficient to provide a smooth guidance of the lifting platform arrangement 4.
Due to the fact that several punching bladders 406 are located on the differently oriented side walls of the demolition member 2, it is difficult to ensure that the individual bladder pressing assemblies 403 are pressed evenly when the punching bladders 406 are inflated. The fixed work platform 401 supported by the air bag pressing assembly 403 may be inclined, so that the following design is made:
