Description

A kind of hoisting machine for assembled steel support dismounting
Technical field
The utility model is related to a kind of hoisting machines for assembled steel support dismounting.
Background technology
The support for being used to support foundation pit peripheral wall is generally both provided in foundation pit, currently, bracing members become foundation pit support Multiple tracks bracing members will be generally arranged in deep basal pit in one main species in the vertical direction, installing first of bracing members When, since space is larger, can be installed more conveniently using first of bracing members of integral hoisting or segmental hoisting pair, and When carrying out second and other bracing members, since the fitting depth of bracing members increases, while there is the steel that installation is completed The obstruction of support when making second and other bracing members, can only carry out, since large-scale is hung in such a way that parts are assembled Installing it is standby can not in margin of foundation pit operation, and since the wide cut of foundation pit is larger, different hanging devices also can not disposably by Parts are lifted to designated position, or are hung out from the removed position of parts.Therefore each parts need first from the edge of foundation pit With the bottom for being hung to foundation pit, then each parts are transported through in foundation pit with small-sized forklift again.It is dismantled to bracing members When, it is that each road bracing members are gradually removed from bottom to top, due to partly building structure being descended to complete at this time, general In the case of, it is impermissible for fork truck and carries out operation in completed building structure, therefore when being dismantled to bracing members, it is necessary to Each parts are first transported to the edge of foundation pit using manual work, are then again hung parts from foundation pit with hanging device Go out.Therefore in foundation pit, in addition to first of bracing members positioned at top layer, other bracing members installation with remove efficiency compared with It is low.
Utility model content
The purpose of the utility model is to overcome drawbacks described above, low with dismounting with the installation for solving bracing members in the prior art The problem of efficiency, for this purpose, the utility model proposes following technical solutions:
A kind of hoisting machine for assembled steel support dismounting is equipped with top layer support above the bracing members, should There are two parallel girders, the hoisting machine to be characterised by comprising pedestal, be mounted on the base hoist engine and hang for top layer support Vehicle, wherein pedestal include the idler wheel of mobile platform and installation on a mobile platform, and the pedestal can assembled through roller supporting On two parallel girders of formula top layer support, under the effect of external force, pedestal can be moved along the extending direction of girder; Crane includes turntable, arm, hoisting motor, lifting rope and swing handle, and the turntable is rotatably installed on a mobile platform, One end of arm is fixed on turntable, and the other end of arm is free end, and pulley is equipped on the free end of arm, lifting rope One end is fixed on the output shaft of hoisting motor, and the other end of lifting rope is lifting around being draped down to form lifting end after pulley Suspender is installed, hoisting motor and swing handle are fixedly mounted on turntable on end.
Hoisting machine in the utility model is suitable in the support system at least with twice support in the up-down direction, In this hoisting machine before use, installation is completed in the top layer support positioned at top side, hoisting machine is arranged in top layer support, by top layer Moving track of the two parallel girders of support as hoisting machine.When installing the bracing members below top layer support, first will Hoisting machine is placed on two girders of top layer support, then the traction rope on hoist engine is fixed to the edge of foundation pit, then Start hoist engine, hoisting machine is moved to the edge of foundation pit, then operate crane, it would be desirable to which the parts of installation are fixed to lifting rope On, and make parts suspention in the air, then start hoist engine, hoisting machine is moved to the installation site of parts substantially just Top operates crane, parts is placed into foundation pit, under the cooperation of installation personnel, parts are installed in place.It is dismantling When the bracing members of top layer support lower section, hoisting machine is moved to the substantially surface for the parts for needing to dismantle in advance, will be completed The parts of dismounting are fixed on lifting rope, then operate crane, after parts are lifted to certain altitude, restart hoist engine, Hoisting machine is moved to margin of foundation pit, parts are unloaded to foundation pit side, and have special transloading equipment to transport specified ground Point.
After the utility model, when installing bracing members, can easily and flexibly parts from the edge of foundation pit transport to Then specified position is transferred in the top of installation site, and can also play the role of being lifted parts.In dismounting steel branch When support, the parts disassembled equally can be easily and flexibly transported to the edge of foundation pit.Due to increasing parts Travelling speed can effectively accelerate the installation or removal speed of bracing members, improve efficiency.
Further, further include for the guide plate on the girder that top layer supports.It, can be to avoid after guide plate is set Hoisting machine causes idler wheel to exceed girder outward in moving process, since moving direction deviates, and has so as to cause hoisting machine It topples dangerous tendency.Preferably, angle steel, the girder that angle steel is supported along top layer have been removably installed in top layer support Extending direction setting, one side of angle steel, which vertically upwardly extends, is formed as the guide plate.
Further, to avoid hoisting machine that rigid friction occurs with guide plate in moving process, prevent hoisting machine from more It successfully moves, the directive wheel being resisted against on guide plate is installed on a mobile platform.
Specifically, two hoist engines are provided on pedestal, two hoist engines are separately positioned on the moving direction of pedestal Opposite both sides.Above-mentioned design can enable hoisting machine be moved on the extending direction of girder more flexiblely, improve work Make efficiency.
Further, the hoist engine include holder, the wire spool that is rotatably mounted on holder, the fixed peace on wire spool Equipped with the hand wheel for rotating wire spool.It, can be in the case where power supply be insufficient or does not have power supply after hand wheel is set Hoisting machine is continued to operate.
