Abstract
The utility model relates to a U-shaped rib drilling device, which is characterized by comprising a mold drilling plate (1), a drilling jig frame (2) and positioning molds (3). The positioning molds (3) are parallelly arranged on the drilling jig frame (2) in pair, limiting blocks (4) are disposed on the positioning molds (3), the mold drilling plate (1) is flatly placed on a drilled surface of a U-shaped rib (5), a tapered wedge I (7) is disposed between a baffle plate (6) of the drilling jig frame (2) and a circular surface of the U-shaped rib (5), and the drilled surface of the U-shaped rib (5) and the edge of the mold drilling plate (1) are fixed to the limiting blocks (4) by the aid of tapered wedges II (8). Hole positions are set by the mold drilling plate according to a standard spatial distance, the U-shaped rib required to be drilled is fixed by the drilling jig frame, and the drilling device can guarantee matching precision of drilled bolt holes and bolt holes of bridge sites, and brings convenience for classified management of U-shaped ribs.
Description
Technical field
The utility model relates to a kind of U rib drilling equipment, is mainly used in bridge and connects.
Background technology
The connected mode that bridge steel box girder adopts the bolt weldering to combine, can conveniently set up, shorten installation period, reduce labour intensity, improve steel case beam fatigue behaviour, prolong service life of bridge, obtain good benefit, have broad application prospects.The U rib connects through splice plate as the ribbed stiffener of floorings, and U rib two stomidium crowd spacings are decided to be normal pitch, and U rib connecting plate two stomidium crowd spacings change with adjacent beams segment length difference.Because drilling hole amount is big, the bridge location matching precision requires high, must adopt a kind of effective U rib bore process and positioning clamping device, just can guarantee bridge location bolt hole matching precision, can be convenient to the Classification Management of U rib connecting plate again.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of U rib drilling equipment that can guarantee bridge location bolt hole matching precision is provided.
The purpose of the utility model is achieved in that a kind of U rib drilling equipment; It comprises mould perforated plate, boring moulding bed and positioning module; Said positioning module is set in parallel on the boring moulding bed in pairs; On said positioning module, be provided with limited block, said mould perforated plate lies against on the bore surfaces of a U rib, and said mould perforated plate lies against on the U rib bore surfaces; Between the baffle plate of said boring moulding bed and U rib disc, tapered wedges I is set, the edge of said U rib bore surfaces and mould perforated plate fixes through tapered wedges II and limited block.
Compared with prior art, the beneficial effect of the utility model is:
The mould perforated plate of the utility model sets the position, hole according to standard null crowd spacing, fixes the U rib that needs boring through the boring moulding bed, and this drilling equipment can be guaranteed the bolt hole of the system of boring and the matching precision of bridge location bolt hole, is convenient to the Classification Management of U rib again.

Fig. 1 is the structural representation of the utility model.
Wherein:
Mould perforated plate 1
Boring moulding bed 2
U rib 5
Baffle plate 6
Tapered wedges I 7
Tapered wedges II 8.
The specific embodiment
Referring to Fig. 1; The utility model relates to a kind of U rib drilling equipment; It comprises mould perforated plate 1, boring moulding bed 2 and positioning module 3, and said positioning module 3 is set in parallel on the boring moulding bed 2 in pairs, on said positioning module 3, is provided with limited block 4; One end of one U rib 5 is positioned on the positioning module 3; Said mould perforated plate 1 lies against on U rib 5 bore surfaces, between the baffle plate 6 of said boring moulding bed 2 and U rib 5 discs, tapered wedges I 7 is set, and the edge of said U rib 5 bore surfaces and mould perforated plate 1 fixes with limited block 4 through tapered wedges II 8.
During drilling, the U rib is placed positioning module (putting in pairs about U rib jig), U rib bottom is withstood by limited block; And its one side is close to positioning module, bore surfaces is positioned over the mould perforated plate on the bore surfaces up and horizontal positioned; Two ends boring can be carried out after adopting cut sth. askew piece and the clamping of mould perforated plate in U rib top, after U rib one sidetracking hole finishes, removes the mould perforated plate; The U rib is overturn; Treat that bore surfaces and place horizontal level, is positioned over the mould perforated plate and treats on the bore surfaces up, accurately the location clamps the back and bores system opposite side bolt hole.After U rib two side holes all completes, remove and bore next root U rib of system.
