Abstract
The utility model relates to an auxiliary installation device, in particular to a U-rib assembling device of a steel box girder. The U-rib assembling device is characterized in that: the U-rib assembling device comprises a jig, a walking trolley, a floating girder and a clamping tool; the jig is composed by the connection of a connecting transverse girder, track girders and a track; the track girders are connected at the two head ends of the connecting transverse girder, the track is supported on the track girders, the walking trolley walks on the track, the floating girder is connected on the walking trolley, the clamping tool is connected under the floating girder, the walking trolley is provided with an regulating handle, a top plate or a bottom plate is arranged on the connecting transverse girder, and U-ribs are distributed at the installing position of the top plate or the bottom plate. The U-rib assembling device reduces the clamping tool fixed on the top plate or the bottom plate when the U-ribs are completely assembled by manual labor, and does not need to carry out extra firing on the top plate or the bottom plate, thereby simplifying the operating procedures, lowering the probability of accidents due to the floating girder is driven by machinery in a forced manner, and greatly reducing the equipment running cost. Moreover, the clamping tool can be conveniently adjusted at both the horizontal and vertical positions; in addition, the positioning is correct, the entire device is simple as well as practical, and the cost is low.
Description
Technical field
The utility model relates to a kind of auxiliary erection equipment, relates in particular to a kind of device that is used for the U rib assembling of auxiliary steel case beam.
Background technology
Steel case beam is the steel plate box-girder again, is long-span bridge beam form of structure commonly used, uses more and more widely.Need the U rib of assembling generally more on steel case back plate or the base plate, if only by artificial assembling, then labour intensity is bigger, and production efficiency is lower, and will additionally get angry to top board or base plate, and is influential to its quality.Therefore be necessary the U rib assembling of existing steel case beam is improved, to reduce hand labor intensity.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of U rib assembling device that reduces the steel case beam of hand labor intensity, minimizing holding clamp.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of U rib assembling device of steel case beam, it is characterized in that: it includes moulding bed, walking dolly, floating beam, jig, moulding bed is by connecting crossbeam, rail beam, track is formed by connecting, connect crossbeam two head ends and be connected with rail beam, rail beam upper support track, walking dolly is walked in orbit, be connected with floating beam on the walking dolly, be connected with jig under the floating beam, walking dolly is provided with the regulating handle that can regulate the floating beam upright position, and the top board of welding U rib or base plate are placed on and connect on the crossbeam, and the U rib is arranged in top board or base plate installation site.
Preferably, the utility model can also possess following technical characterictic:
Described floating beam lower end and jig abutting end offer the bolt hole group pattern of regulating according to U rib horizontal level.
Described regulating handle is connected with floating beam by screw pair.
Described connection crossbeam is an i iron.
Described rail beam is a H shaped steel.
The utility model utilizes walking dolly to drive to be connected under the floating beam jig to walk together, is fixed on the jig on top board or the base plate when having reduced merely by artificial assembling U rib; Carry out the electric welding welding behind the chucking, do not need top board or base plate are additionally got angry, simplified operational sequence; Drive floating beam with walking dolly, reduced, also reduced the running cost of equipment significantly because of floating beam drives the accident occurrence probability that brings by mechanical forced; Jig all can be regulated easily at horizontal level and upright position, and accurate positioning, and whole device is simple and practical, with low cost.
Description of drawings
Fig. 1 is the utility model embodiment vertical view;
Fig. 2 be among Fig. 1 A-A to enlarged drawing;
Fig. 3 be among Fig. 2 B-B to enlarged drawing;
Among the figure: the 1-walking dolly, the 2-floating beam, the 3-rail beam, 4-connects crossbeam, 5-track, 6-jig, 7-U rib, 101-regulating handle, 102-wheel, 201-bolt hole group pattern, 202-floating beam slideway.
The specific embodiment
In order to understand the utility model better, below in conjunction with embodiment and accompanying drawing the technical solution of the utility model is described further, referring to Fig. 1 to Fig. 3:
Press the U rib assembling device of a kind of steel case beam of the utility model enforcement, it includes moulding bed, walking dolly 1, floating beam 2, jig 6, moulding bed is by connecting crossbeam 4, rail beam 3, track 5 is formed by connecting, connecting crossbeam 4 is i iron, rail beam 3 is that two elongated H shaped steel are connected two head ends that connect crossbeam 4, connecting crossbeam 4 is connected with rail beam 3 axis normal, connect crossbeam 4 and be many compositions of pitch arrangement rigid platfor, the top board or the base plate of welding U rib 7 are placed on the platform that connects crossbeam 4 compositions, U rib 7 is arranged in top board or base plate installation site, and U rib 7 openends are downward.Connect track 5 on the rail beam 3, the wheel 102 of walking dolly is walked on track 5, be connected with floating beam 2 on the walking dolly 1, floating beam 2 ends are connected with walking dolly 1, floating beam is installed with jig 62 times, walking dolly 1 is provided with regulating handle 101, regulating handle 101 and floating beam 2 are connected by screw pair, rotation regulating handle 101 can make floating beam 2 move up and down along floating beam slideway 202, thus regulate jig 6 from the vertical distance of U rib 7 in U rib 7 is bumped into the socket of jig 6 with its chucking.The located lateral of U rib 7 is cooperated with bolt hole group pattern 201 by jig 6 regulates, and the bolt hole on the jig 6 adopts slotted hole directly to finely tune, and need change and U rib 7 corresponding jigs when adjusting greatly.
The course of work of the present utility model is: earlier steel case back plate or base plate are placed on the connection crossbeam 4 of moulding bed, draw the position line that U rib 7 is installed at top board or above the base plate according to design drawing then, then U rib 7 is placed on top board or the base plate by the setting-out position, again floating beam 2 is moved to U rib 7 sky, adjust behind U rib 7 positions and jig 6 sockets to be pressed in U rib 7 external surfaces and to adjust behind the bolt fixing, again with U rib 7 and top board or base plate spot welding, continue mobile floating beam 2, continue spot welding U rib 7 U rib 7 spot welding on whole apparatus for assembling and finish, then assembly working is finished.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
