Abstract
The utility model discloses an auxiliary device for overturning a large-size plate girder component. The auxiliary device comprises a flat plate, wherein at least one semicircular turning plate is arranged at the bottom of the flat plate; a diameter edge of the turning plate is welded at the bottom of the flat plate; and a symmetrical axis of the turning plate is vertical to the flat plate. In a turning process of the auxiliary device, a supporting force on the ground is utilized to assist in overcoming gravity, so that the bearing force of a portal crane is reduced, the portal crane can be used for turning a heavier component within a certain scope, the investment in equipment is saved, and meanwhile, the component is never separated from the ground in the whole overturning process, so that the component is prevented from swinging in air and the safety of workers in the overturning process is ensured.
Description
Technical field
The utility model relates to a kind of servicing unit, specifically is meant a kind of servicing unit that is used for large-scale plate-girder member upset.
Background technology
Steel construction be by shaped steel and steel plate through welding, bolt is connected or rivet the engineering structure of processing.Because how shaped steel it adds man-hour as beam or post, whole length is bigger, for the beam slab class A of geometric unitA of large span or length; Its weight is big, all is tons up to a hundred usually, even weighs 300 tons; For the transportation of shaped component, upset etc., all need upset, normally steel structure processing of portal jib crane, produce, lifting is requisite; But under the certain situation of existing equipment, might need the bigger member of upset weight, for example; Existing equipment is 150 tons portal jib crane, and 200 tons the member of how overturning it seems to be difficult to realize at present.
The utility model content
The purpose of the utility model is to provide a kind of servicing unit that is used for large-scale plate-girder member upset, during greater than the peak of existing equipment, utilizes servicing unit and existing equipment to carry out the upset of large-scale beams and slabs in upset weight.
The purpose of the utility model realizes through following technical proposals:
A kind of servicing unit that is used for large-scale plate-girder member upset comprises flat board, is provided with a semicircle rotor plate at least in said dull and stereotyped bottom, and the diameter side weld of rotor plate is connected on dull and stereotyped bottom, and the symmetry axis of rotor plate is perpendicular to flat board.Because most shaped steel class beam slab is H type member, when counter-rotating, needs one are edge-on in ground, then upset; So, adopt a flat board, the semicircle rotor plate of at least one is installed on flat board, the axis of semicircle rotor plate is with dull and stereotyped vertical; The circular arc of semicircle rotor plate is positioned at dull and stereotyped below, during use, flat board is fixed on the member bottom, when member is pulled; Member falls down to the ground under the rotary action of semicircle rotor plate, and in this process, the gravity of member is decomposed into two, the support force of rotor plate and the pulling force of portal jib crane; In rotation process, the holding power on ground helps to overcome gravity, has reduced the holding capacity of portal jib crane, makes portal jib crane in certain scope; The big slightly member of weight that can be used to overturn, the input of having practiced thrift equipment, simultaneously; The equal built on stilts not of member has been avoided the skyborne swing of member in the whole switching process, can ensure the safety of workers in the switching process.
Said rotor plate is one, and rotor plate is positioned at dull and stereotyped middle part.Further say,, for member length less the time, be employed in dull and stereotyped below and a rotor plate is installed get final product,, usually rotor plate is installed in the centre position bottom dull and stereotyped in order to keep balance as the further improvement of the utility model.
Said rotor plate is two or more, is parallel to each other between the rotor plate.Further say,,, when length is big, can be employed in the form that two or more rotor plates are installed in dull and stereotyped below, promptly can keep balance, can disperse stressed again when the weight of member is bigger as the further improvement of the utility model.
On said rotor plate, be connected with cylinder.Further say,,, can be employed in the form that semicircle cylinder is installed on the circular arc of rotor plate, increase the contact-making surface with ground, reduce the pressure that ground receives for the pressure that makes ground bear reduces as the further improvement of the utility model.
The utility model compared with prior art has following advantage and beneficial effect:
A kind of servicing unit that is used for large-scale plate-girder member upset of 1 the utility model, the gravity of member is decomposed into two, the support force of rotor plate and the pulling force of portal jib crane; In rotation process, the holding power on ground helps to overcome gravity, has reduced the holding capacity of portal jib crane; Make portal jib crane in certain scope, the big slightly member of weight that can be used to overturn, the input of having practiced thrift equipment; Simultaneously; The equal built on stilts not of member has been avoided the skyborne swing of member in the whole switching process, can ensure the safety of workers in the switching process;
2 the utility model are a kind of to be used for the servicing unit of large-scale plate-girder member upset, for member length less the time, is employed in dull and stereotyped below and a rotor plate is installed is got final product; In order to keep balance, usually rotor plate is installed in the centre position of dull and stereotyped bottom, when the weight of member bigger; When length is big; Can be employed in the form that two or more rotor plates are installed in dull and stereotyped below, promptly can keep balance, can disperse stressed again;
3 the utility model are a kind of to be used for the servicing unit of large-scale plate-girder member upset, is employed in the form of on the circular arc of rotor plate semicircle cylinder being installed, and increases the contact-making surface with ground, reduces the pressure that ground receives.

The specific embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the embodiment of the utility model is not limited thereto.
Embodiment one
As shown in Figure 1, a kind of servicing unit that is used for large-scale plate-girder member upset of the utility model comprises dull and stereotyped 1; Dull and stereotyped 1 is rectangle on the whole; It adapts less than member greatly, two rotor plates 2 is installed, rotor plate 2 semicirculars in shape in dull and stereotyped 1 bottom; According to the length of flat board 1, can increase or reduce the quantity of rotor plate 2.
Embodiment two
As shown in Figure 2, the difference of present embodiment and embodiment one only is: on the circular arc of rotor plate 2, be connected with cylinder 3, it is half-cylindrical that cylinder 3 is.
As shown in Figure 3, in use, with this device of bottom fixed installation of member, with rotor plate 2 or cylinder 3 kiss the earths, dull and stereotyped 2 upper surface is connected the member bottom, can fix through modes such as spot welding.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction, every according on the technical spirit of the utility model to any simple modification, equivalent variations that above embodiment did, all fall within the protection domain of the utility model
