Description
Technical field
The utility model relates to a kind of acclerating road switch concrete slab sleeper plastic bushing and drills through device and pre-embedded device.
Background technology
At present, the China railways raising speed railway obtained good economic benefit and social benefit, but wearing and tearing and damage has in various degree also appearred in speed-raising equipment through in a few years operation.The major issue that parts that repairing or replacing have damaged or equipment are guarantee railway safety, changing the concrete slab sleeper T30 high-strength nylon plastic bushing that has damaged is exactly current urgent problem.But because acclerating road switch required precision height, complex process uses existing instrument or equipment to repair maintenance normally, does not reach technical requirements far away, even also phenomenon can occur scrapping.
Summary of the invention
The technical problem that the utility model solves: design a kind of acclerating road switch concrete slab sleeper plastic bushing and drill through device and pre-embedded device, according to datum coincidence, the design principle that error is little has solved the difficult problem that acclerating road switch T30 plastic bushing is changed.
Technical solution of the present utility model:
A kind of acclerating road switch concrete slab sleeper plastic bushing drills through device, locating shaft (2) is housed in the inner chamber of its hollow boring bit (1), and the axis of the axis of locating shaft (2) and hollow boring bit (1) coincides, the lower surface 10-15mm of the outstanding hollow boring bit (1) of the lower end of locating shaft (2).
A kind of acclerating road switch concrete slab sleeper plastic bushing pre-embedded device, location cutterhead (3), locating shaft (5) and connecting axle (7) by annular are formed, the upper surface of location cutterhead (3) is fixed with installation shaft (4), locating shaft (5) or connecting axle (7) are housed in the inner chamber, and the axis of installation shaft (4), locating shaft (5) and connecting axle (7) coincides with the axis of locating cutterhead (3) all.Be shaped on blade (6) on the lower surface of location cutterhead (3), the lower surface 10-15mm of the lower end of locating shaft (5) outstanding location cutterhead (3).The bottom of connecting axle (7) is shaped on external screw thread (8).
The utility model is compared with prior art novel in design, and is simple in structure, and construction safety, simply, has easily and fast improved operating efficiency and quality requirement greatly.The new plastic sleeve pipe of changing and the plastic bushing center displacement degree of damage are no more than 1 millimeter, have satisfied the acclerating road switch required precision, have ensured safety of railway traffic.

Fig. 2 is the structural representation of the utility model pre-embedded device,
Fig. 3 is the structural representation of the utility model connecting axle.
The specific embodiment
1,2,3 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of acclerating road switch concrete slab sleeper plastic bushing drills through device, be provided with locating shaft (2) in the inner chamber of its hollow boring bit (1), and the axis of the axis of locating shaft (2) and hollow boring bit (1) coincides, the lower surface 10-15mm of the outstanding hollow boring bit (1) of the lower end of locating shaft (2).
A kind of acclerating road switch concrete slab sleeper plastic bushing pre-embedded device, location cutterhead (3), locating shaft (5) and connecting axle (7) by annular are formed, the upper surface of location cutterhead (3) is fixed with installation shaft (4), locating shaft (5) or connecting axle (7) are housed in the inner chamber, and the axis of installation shaft (4), locating shaft (5) and connecting axle (7) coincides with the axis of locating cutterhead (3) all.Be shaped on blade (6) on the lower surface of location cutterhead (3), the lower surface 10-15mm of the lower end of locating shaft (5) outstanding location cutterhead (3).The similar circular milling cutterhead of location cutterhead (3).The bottom of connecting axle (7) is shaped on external screw thread (8).
Using method:
Benchmark location: the location cutterhead (3) of the annular coupling spindle (4) by its upper surface is fixed on the auger, locating shaft (5) in its inner chamber is inserted in the plastic bushing that has damaged, starting auger then, to mark with T30 plastic bushing axle center on the plastic bushing sleeper plane of having damaged be the center of circle, about 80 millimeters of diameter, section is leg-of-mutton annular baseline trough, and the nonconcentricity that makes annular baseline trough and the T30 plastic bushing that damaged is in half millimeter.
Drill through the plastic bushing that has damaged: diamond is located hollow boring bit (1) be fixed on the auger, locating shaft (2) in its inner chamber is inserted in the plastic bushing that has damaged, start the good locating hole of boring machine drill then, then locating shaft (2) is unloaded the plastic bushing that can will damage that continues to hole and take out.Location major axis in the hollow boring bit has solved common hollow diamond drilling bit and easily walked, bored inclined to one side problem when rough drill.Guaranteed that the stiffener in the concrete slab sleeper is not damaged, and guarantees that the concrete slab sleeper quality is unaffected.
Pre-buried new plastic bushing: change locating shaft (5) into connecting axle (7), new T30 plastic bushing is connected the lower end of connecting axle (7), in the hole of having bored, inserting sulphur rivet clasp material then, again the T30 plastic bushing is inserted in the hole of having bored, and the lower surface of location cutterhead (3) and the annular baseline trough drawn are coincide (datum coincidence), treat will locate behind the sulphur rivet clasp material solidification cutterhead (3) and withdraw from and get final product.So both guarantee T30 plastic bushing center displacement degree, guaranteed the verticality of T30 plastic bushing and concrete slab sleeper again, and sulphur rivet clasp quality height.Thoroughly solved in the past in the construction because of the T30 plastic bushing pre-buried after, with the via hole decentraction of 32 millimeters of sliding bed platen diameters, and cause scrap phenomenon.
The utility model can adopt hand-held and fix two kinds of methods of operating.Hand-held can carry out job execution under the situation that does not influence driving, for traffic safety provides guarantee.Hand-held about 20 minutes end of operations of operation.Fixed operation can be at large-area construction operation under the road, efficient height, laborsaving.About 10 minutes end of operations of fixed operation.
