Abstract

The utility model relates to an electromagnetic positioning steel rail circuit hole drilling machine, which is used for drilling circuit holes on steel rails and is mainly composed of an electromagnetic control box, a left and a right magnetic bases, an electric drill, a feeding handle, a lead screw and embedded nuts thereof, a leading screw and guide sleeve and a drilling base. The left and the right magnetic bases are square column-shaped, an upper surface of the right magnetic base is provided with the electromagnetic control box, a wire bundle is arranged between the left and the right magnetic bases, and two parallel vertical guide bars are arranged on the front and back surfaces of the left magnetic base. The guide bar is provided with a guide sleeve, the center of a connection plate at the upper end of the guide bar is provided with a vertical lead screw, the lead screw is provided with embedded nuts, the guide sleeve and the embedded nuts are connected with a drilling base on the left side, and the drilling base is provided with a vertical electric drill. The utility model has the characteristics of safe utilization, rapidity and convenience disassembly, good hole drilling quality and high precision.

Description

Electromagnetic location rail circuit hole rig

The utility model relates to railway track circuit hole rig new varieties.

Existing railway track circuit hole rig fixed form is an overhead, and frame is located on rail, and in the boring of middle part, rail side, this fixed form is dangerous, and train has come, just in case have little time to withdraw, can cause a serious accident; It adopts lever or rack-and-pinion feed, require great effort very much, also be easy to generate displacement, the hole that gets out is of poor quality, and trueness error is big, the auger that has is for its safety, fixed form changes underneath type into, promptly be hooked on the rail foot surface and locate, but loading and unloading is inconvenient, in major station track switch place how or platform, can not use on the no stone ballast roadbed rail, lose its practicality.

The purpose of this utility model is to provide a kind of positioning security, feed is laborsaving, drilling quality is good electromagnetic location rail circuit hole rig.

The utility model is that the locate mode that adopts the electromagnet support to be adsorbed on the rail side achieves the goal with the feed mode that adopts feed screw nut pair, line bag by the enamel-covered wire coiling is set between 2 magnetic supports, produce magnetic field during the energising of line bag, magnetic support just produces the required magnetic attraction in location.

Characteristics of the present utility model: the one, safe and reliable, dismounting is convenient rapidly, and after the outage, magnetic force disappears, and can unload rig 2 seconds easily, and it is lower than plane on the rail in working order the time, even just in case have little time to unload, also can not influence normal driving; The 2nd, drilling quality is good, and circle is just smooth, the precision height, and the advance and retreat cutter is all very brisk evenly.

Below in conjunction with accompanying drawing embodiment is described:

Fig. 1 is this machine duty partly cut-away vertical view.

Fig. 2 abandons electric drill partly cut-away left view for this machine unloads.

With reference to Fig. 1-2, this machine is by electronicmagnetic control box (1), right magnetic support (2), left side magnetic support (5), line bag (3), axle (4), feed handle (6), nut (7), single direction thrust ball bearing (8), connecting plate (9), edge cover nut (10), screw mandrel (11), metal annulus (12), felt pad (13), steel bushing (14), flexible insulating layer (15), enamel-covered wire (16), insulating board (17), binding (18), prick strap (19), guide rod (20), guide pin bushing (21), boring anchor (22) and electric drill (23) are formed, a left side, right magnetic support (5,2) be cubic cylindricality, on right magnetic support (2) upper surface, be equipped with electronicmagnetic control box (1), axle (4) both ends are positioned on a left side, on the right magnetic support neck circular hole, axle is equipped with line bag (3) outward, line bag (3) is by steel bushing (14), metal annulus (12), felt pad (13), flexible insulating layer (15), enamel-covered wire (16), insulating board (17), binding (18) and bundle strap (19) are formed, 2 parallel guide rods (20) bottom is a square body, last middle part is a cylinder, it is preceding that the bottom is fixed on left magnetic support (5), on the back, guide pin bushing (21) is enclosed within on the guide rod (20), boring anchor (22) is a channel steel shape, be equipped with electric drill (23) in the seat, the seat end, be fixed on the guide pin bushing (21), connecting plate (9) two ends are connected with guide rod (20) upper surface, screw mandrel (11) top polished rod is positioned on connecting plate (9) mesopore with single direction thrust ball bearing (8) and nut (7) thereof, the bottom screw mandrel cooperates with the edge cover nut (10) that is positioned on the beneath center of boring anchor (22), and screw mandrel (11) top is equipped with feed handle (6).
