Abstract
The utility model relates to a screw spike puller of rail cement sleeper, which is composed of a base (3), a pulling bar (4), an elastic cone head (5), a tightening bar (6), a lifting nut (7), a snap ring (8) and a thrust bearing (9). The utility model is characterized in that: the pulling bar (4) is a hollow bar with external thread; a conical surface (11) matched with the elastic cone head (5) is provided with the pulling bar (4); a plurality of elastic slots are provided at the conic section of the elastic cone head; a inclined plane (12) (13) for avoiding the convex plane of sleeper and the rail base of rail is provided on the base; the tightening bar (6) can be pulled out. While in use, the pulling bar (4) is screwed into the base (3) and laid on the sleeper (1), enabling the screw spike (2) to penetrate the pulling bar; the elastic cone head (5) is tightened on the screw thread of the spike by means of the tightening bar (6), when tightened, fetching the tightening bar (6), so as to prevent that the tightening bar (6) is too high and extended the driving limitation, then screwing the lifting nut (7), screwing out of the pulling bar (4), while the screwing process, the screw spike is clamped by the elastic cone head (5) with the help of the pulling bar (4) moving forward the direction of screwing out together with the pulling bar, the base is pressed toward the sleeper, and enabling to break the adhesive force between the spike the part of which is anchored into the sleeper and anchor sulfur mortar, so that the spike can be pulled out.
Description
Technical field
The present invention relates to a kind of puller of railway concrete sleeper screw spike.
Background technology
With the sulphur-bonded mortar anchoring four screw spikes are arranged on the railway concrete sleeper, in order to fixing rail.When railway spike has problem to pull out, but not too easy.Now generally be again railway spike to be extracted after adopting hollow boring bit that the mortar around the railway spike is machined away, as " concrete sleeper bolt the extractor " (patent No.: 96234668).Because railway non-transformer along the line need carry small generator and go to, equipment is heavier, and work is inconvenient.
Summary of the invention
The purpose of this utility model is the puller of a kind of screw spike of design, and it can utilize the running interval time to operate, and does not influence traffic safety.
The utility model is achieved in that sleeper screw spike extractor is made up of the hollow dead man of base, lifting nut, band external screw thread and inner conical drogue, tapped elasticity conehead etc.The elasticity conehead is screwed on the screw spike, and when screwing out the screw thread dead man, tapered sleeve can clamp the elasticity conehead, and it is pulled out screw spike from concrete sleeper.
Compare with original technology, the present invention is simple to operate, need not power source, is easy to carry, and is one of ideal tools of railway maintenance department.
Description of drawings
Accompanying drawing is the operating position assembling schematic diagram of sleeper screw spike extractor.
The specific embodiment
Describe below in conjunction with accompanying drawing:
The utility model is by base (3), and dead man (4), is tightened bar (6), lifting nut (7), snap ring (8) and thrust bearing (9) and formed elasticity conehead (5).Dead man (4) is for being with externally threaded hollow stem, and be processed with the conical surface (11) that matches with elasticity conehead (5), the tapering of elasticity conehead also is processed with some elastic grooves (10), be processed with inclined-plane (12) and (13) for the projecting surface of avoiding sleeper and the flange of rail of rail on the base, the bar of back-outing (6) can take out.
Operating principle of the present utility model is as follows: dead man (4) is screwed in base (3) be placed on the sleeper (1), screw spike (2) is penetrated wherein, with tightening bar (6) elasticity conehead (5) is screwed on the screw thread of railway spike, twist and to tighten bar (6) after good and take out, in case it is too high and invade the driving gauge to tighten bar.Twist lifting nut (7) again, dead man (4) is back-outed, in the process of back-outing, elasticity conehead (5) is under the effect of dead man (4) conical surface, screw spike is clamped, and with dead man to the direction of back-outing motion, base but compresses to sleeper, thereby makes the railway spike that anchors into the sleeper part with the destruction of the cementation between the anchoring sulphur-bonded mortar and railway spike is extracted.The effect of thrust bearing (9) is in extracting the process of railway spike, makes dead man keep rectilinear motion and does not rotate.
The utility model can also be implemented like this: lifting nut (7) and base (3) are made of one, cancellation snap ring (8) and thrust bearing (9), promptly in the endoporus of base (3), be processed with dead man (4) and go up the internal thread that external screw thread matches, only need rotate dead man (4) when pulling out railway spike, also can railway spike be extracted by the dead man (4) and the relative motion up and down of base (3).
Claims (5)
1, sleeper screw spike extractor is characterized in that; It is by base (3), dead man (4), elasticity conehead (5) and tighten the screw spike extractor that bar (6), lifting nut (7), snap ring (8), thrust bearing (9) are formed, dead man (4) is a cone match with elasticity conehead (5), tighten bar (6) and can insert in the hole on elasticity conehead (5) top, elasticity conehead (5) is screwed on the screw spike.
2, according to claims 1 described sleeper screw spike extractor, it is characterized in that: be processed with the internal thread that cooperates with railway spike on the elasticity conehead of sleeper screw spike extractor, the tapering has some elastic grooves (10).
3, according to claims 1 described sleeper screw spike extractor, it is characterized in that: the dead man of sleeper screw spike extractor is a hollow, the bottom of bar is processed with the awl (11) that matches with the elasticity conehead, and the outside of bar is processed with the screw thread that matches with lifting nut.
4, according to claims 1 described sleeper screw spike extractor, it is characterized in that: the bottom of the base of sleeper screw spike extractor is processed with inclined-plane (12) that adapts with the sleeper shape and the inclined-plane (13) that adapts with rail foot.
5, according to claims 1 described sleeper screw spike extractor, it is characterized in that: the base of sleeper screw spike extractor, be processed with the internal thread that matches with external screw thread on the dead man in its endoporus, the bottom is processed with inclined-plane (12) that adapts with the sleeper shape and the inclined-plane (13) that adapts with rail foot.
