Description
Technical field
Auxiliary device when the utility model relates to be dismantled to the supporting beam being mounted in foundation pit, and in particular to be used for
The hoistable platform of foundation pit supporting beam disassembly.
Background technique
The chief component of support system one of of the supporting beam as foundation pit, support in the dismounting second layer and more on the lower
Liang Shi, it is general using cutting or on the spot decomposing supporting beam by building block, then again by building block using artificial auxiliary
Mechanical mode is helped to transport foundation pit.For the supporting beam of top layer, since operating space is larger, generally for the less base of width
Hole is usually arranged crane at the edge of foundation pit, is segmented supporting beam using crane and hangs foundation pit, and base biggish for width
Hole, since the limitation of length of boom and the support strength of margin of foundation pit are limited, crane can only be to supporting beam close to margin of foundation pit
Part hung, and supporting beam can not be hung apart from the farther away part of margin of foundation pit, for this of supporting beam
Part-structure is removed by the way of carrying out supporting beam to be decomposed into components at present, and this method for dismounting not only needs
Consuming is a large amount of artificial, and operating efficiency is lower, affects the progress of whole building construction.
Utility model content
The purpose of the utility model is to overcome drawbacks described above, provide a kind of lifting that supporting beam dismounting speed can be improved
Platform, to improve the efficiency of construction, specific technical solution is as follows:
For the hoistable platform of foundation pit supporting beam disassembly, the supporting beam is arranged horizontally on the column in foundation pit, the liter
Drop machine is characterised by comprising lifting device, support device and jacking apparatus；The lifting device includes bottom plate, top plate and branch
The hydraulic lifting frame between top plate and bottom plate is supportted, hydraulic lifting frame can push top when elongating or shortening along the vertical direction
Plate is raised and lowered；The support device includes backing plate and at least two support rods, lifting device are arranged in the pad of support device
On plate, at least two support rods arrange that the bottom end of support rod is removably mounted on backing plate around lifting device, work as liter
The top plate of falling unit is jacked up by hydraulic lifting frame to after setting position, and the top of support rod is removably mounted on top plate；Top
Rising device can elongate or shorten, and jacking apparatus is mounted on the upside of top plate.Preferably, the jacking apparatus is jack.
Currently, hydraulic lifting frame comparative maturity, model is relatively abundanter, it can satisfy the needs of the application, according to this
The different loads of hoistable platform in application can select the hydraulic lifting frame without model, naturally it is also possible to be customized or from
System.
When dismantling the top layer supporting beam in the supporting beam or Multi-layer supporting beam of single layer setting using the utility model, press first
Supporting beam is divided into several disassembly sections according to the arrangement of column, when needing to remove supporting beam, first by the hoistable platform
It is arranged in the lower section for needing the disassembly section dismantled, then jacking apparatus is extended, jacking apparatus is made to be resisted against disassembly from bottom to top
The downside of section, then separates at the both ends for dismantling section with the other parts of supporting beam, after completing separation, starts jacking apparatus, makes
Jacking apparatus extends upwards, and disassembly section is pushed away original position, then installs temporary track in the lower section of disassembly section, completes interim
After the installation of track, be again started up jacking apparatus, shorten jacking apparatus, will disassembly section transfer on transfer device, using turn
The disassembly section removed is transported to storage area by shipping unit.After the utility model, when dismantling supporting beam, it is no longer necessary to will prop up
Support beam is decomposed into components, but supporting beam is split as several disassembly sections, and disassembly section is disposably transported as a whole
Foundation pit out, compare the prior art, can effectively save the take-down time and shipping time of a large amount of supporting beam, can be effectively
Improve the construction efficiency of building.
It further, further include counter weight device, which includes idler wheel, connecting rope and counterweight, and the idler wheel is rotationally
It is mounted on top plate, one end of connecting rope is fixed on top plate, and the other end of connecting rope after idler wheel up around extending downwardly simultaneously
Connect the counterweight.The decrease speed that can accelerate lifting device using counter weight device improves the removal efficiency of hoistable platform.When
When needing to remove hoistable platform, support rod is removed first, then under by hydraulic lifting frame, rely on hydraulic lifting frame itself merely
Weight and, the retraction speed of hydraulic lifting frame is slower, and after counter weight device be arranged, the retraction for increasing hydraulic lifting frame is fast
Degree, can accelerate the service speed to hoistable platform.
Further, the lifting device further includes bearing plate, which is laid on the upper surface of top plate, the jacking dress
It sets and is mounted on bearing plate.Undertake biggish load since jacking apparatus can generate at work, these load long terms in
When on the top plate of hydraulic lifting frame, top plate can be made to generate a degree of deformation, bearing plate is set, load can be transmitted to hold first
Weight plate, since the deformation that load acts on and generates can also primarily occur on bearing plate, when there is serious deformation in bearing plate,
Bearing plate can be replaced, so that the maintenance to the top plate of hydraulic lifting frame is reduced, to extend the use longevity of entire hoistable platform
Life.
Preferably, for convenience of the transport of support rod and installation, the support rod divides bar removably by the support of at least two sections
It is formed by connecting.After support rod is divided into more piece, the weight of single component can be mitigated, be easily installed the operation of personnel.
Further, bridging is provided between two adjacent support rods.After bridging is set, each support rod can be made
One entirety mutually relied on is formed by state independent, is passed through by the load that jacking apparatus is transmitted on single support rod
Bridging is transmitted to other support rods, the load for passing over all support rod shareds by jacking apparatus.
