Abstract
The utility model discloses an anchor replacing device for a railway concrete sleeper turnout, and belongs to the technical field of maintenance of railway turnouts. The anchor replacing device comprises a base and fasteners, wherein a hollow vertical upright column is connected onto the base; a perpendicular lifter is mounted on the upright column; a motor is fixed on the vertical lifter; a vertical hollow drill is mounted on the output shaft of the motor; the diameter of the inner wall of the hollow drill is larger than that of a nylon casing; fastening through holes are formed in two ends of the base respectively, and inclined side plates are fixed at two ends of the lower surface of the base respectively; the base and cross sections of the side plates are matched with the cross section of the concrete turnout sleeper; and the fasteners comprise L-shaped channel steel and connecting rods perpendicularly fixed at one end of the channel steel, and a thread and a clamp nut matched with the thread are arranged at the upper end of the connecting rod. The position of the device on the concrete turnout sleeper is firm, accurate exerted force of a drill during work is guaranteed; and the device is not damaged easily, light in structure, simple to operate, time-saving and labor-saving, and can replace vertical bolts quickly and improve the work efficiency.
Description
Technical field
The utility model relates to the maintenance technical field of railway switch, and specifically a kind of railway concrete pillow track switch changes anchor device.
Background technology
Along with railway speed raising, for adapting to the development of national economy, for adapting to the needs of railway high speed heavy duty, require the strength and stiffness that rail track is higher, railway switch also develops into concrete crosstie by sleeper,, also there are some disadvantages in coming into operation of concrete crosstie, as concrete crosstie side direction station bolt easily fractures, and be difficult for changing, or due to concrete crosstie boatswain chair, cause nylon sleeve internal thread to lose efficacy, station bolt loses connecting forces.
Situation about now losing efficacy for nylon sleeve, the in the past way in work area: 1, with the φ 45mm water consistent with nylon sleeve diameter, bore hot melt nylon sleeve, while doing due to water driller, need water for cooling, the viscosity after nylon melts, tightly be attached to water drilling pipe inwall, frictional force increases, and motor load is excessive, often burns out motor, not at all easy hole of having bored, after drill bit is taken out, the nylon stick of thawing is on drill bit, and extremely difficulty is cleaned out.Because new sleeve pipe is too small with boring gap, no matter adopt epoxy resin or the agent of DB type spike anchoring, new sleeve pipe and the adhesion stress of concrete crosstie are all poor.2, with alloy tool steel bit, along nylon sleeve, cut, retain the helical form silking of nylon when concrete crosstie is pre-buried, be again screwed into the nylon sleeve newly changing.Owing to being screwed in concrete crosstie connecting forces, compared with station bolt and nylon sleeve, to be screwed into rear torsional moment little, loaded onto after iron chair in the past, then change rail, while needing to remove iron chair, due to " working day and night ", needs cutting.
I once applied for for the concrete crosstie track switch station bolt patent of situation that fractures, but cannot solve the situation that nylon sleeve internal thread lost efficacy, the serious corrosion of station bolt sometimes fractureing and cause Broken bolt to take out with silk fetching equipment.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of railway concrete pillow track switch to change anchor device.
The utility model is achieved through the following technical solutions: a kind of railway concrete pillow track switch changes anchor device, comprises base and for base being fixed on to the securing member on concrete road switch tie; On described base, be connected with the vertical column of hollow that can rotate; The vertical lift device with rocking handle that can move up and down on column is installed on described column; On described vertical lift device, be fixed with output shaft motor straight down; Vertical core drill is installed on described motor output shaft; Described core drill inner diameter is greater than nylon sleeve diameter; Described base two ends respectively have a fastening through-hole, and base lower surface two ends are respectively fixed with inclined side plate; Described base and side plate cross section match with concrete road switch tie section; Described securing member comprises L-type channel-section steel and the connecting rod that is vertically fixed on channel-section steel one end, and connecting rod upper end has screw thread and is provided with the clamp nut coordinating with it.
It is further: described connecting rod is weldingly fixed on channel-section steel one end.
During use, the channel-section steel of two securing members is respectively snapped in to a side of concrete road switch tie, base is placed on concrete road switch tie, the connecting rod of securing member passes the fastening through-hole on base and is fixed together by clamp nut and base.Adjusting vertical lifting device, aims at Broken bolt hole by core drill and carries out perforate, takes out afterwards Broken bolt, nylon sleeve and concrete block.In perforate, put into new nylon sleeve, in the gap between perforate and nylon sleeve, with the agent of DB type spike anchoring, fill fixingly, afterwards, be again screwed into new station bolt after putting backing plate well.
The utility model has the advantage of: the design of base coordinates with concrete road switch tie, fixation, equipment position on concrete road switch tie is firm, and while guaranteeing drill bit work, firmly precisely, equipment is not fragile.Device structure is light, simple to operate, time saving and energy saving, and station bolt or nylon sleeve that energy quick-replaceable damages, increase work efficiency.
