Abstract

The utility model relates to a T-shaped pick which is a pick used for the electric tamping machine with the application number as 86107743. The spire cone pick and the pick palm combined welded structure of the prime requisition electric tamping machine of torsional impact oscillatory type are changed to a T-shaped pick. Because the lower plugging resistance force is decreased and the twisting oscillation mode is improved, the T-shaped pick further improves the lower plugging performance and tamping efficiency of the electric tamping machine of torsional impact oscillatory type. The utility model also has the advantages of simple structure, easy production, good manufacturability, etc.

Description

T-shape pick

The utility model is that to be used for application number be a kind of pick on 86107743 the electric tamper.

The pinnacle cone pick of original application electric tamper and pick palm Combination Welding structure, following slotting resistance is big, and the twisting vibration mode behind the insertion ballast aggregate is that the garden heart carries out twisting vibration with pick cone pinnacle.The pinnacle cone of pick is that the twisting vibration of the garden heart strong point plays inhibition to forming alternately with pick palm two, makes to reduce by the scope of activities of vibration ballast aggregate with by the displacement to pillow end direction between pillow, influences the raising of twisting vibration efficient.

The purpose of this utility model is to reduce the following slotting resistance of pick, improves the twisting vibration mode of pick, improves the following slotting performance and the twisting vibration efficient of electric tamper.

The technical solution of the utility model is that the Welding Structure of the pick of the electric tamper of original application and pick palm combination is changed system into the planform that is cast as one by bottom knife plate and top welding point is the pick of T shape.

The utility model has the advantages that slotting resistance is little under the pick, improved the twisting vibration mode, the following slotting performance and the tamping efficiency of electric tamper are further improved, and have advantages such as good manufacturability easy to manufacture simple in structure.

Fig. 1 is that schematic diagram is looked on the left side that T shape pick is welded on behind the electric tamper tamping rod lower end.

Fig. 2 is the front-view schematic diagram after T shape pick is welded on electric tamper tamping rod lower end.

Fig. 3 is the front-view schematic diagram of T shape pick.

Fig. 4 is that schematic diagram is looked on the left side of T shape pick.

Embodiment of the present utility model is: as shown in Figure 3, Figure 4: the thickness attenuation gradually from top to bottom of the knife plate (2) of T shape pick, being shaped as by two of knife plate (2) top edge has a gradient that raises gradually to the centre, and realizes that with the two sides of welding point (3) transition is connected with garden arc curve.The welding point (3) on T shape pick top passes through with the knife plate (2) of bottom with a little catotropic cone mutually for widely different turning, and the top of welding point (3) is axle (4).The material and the manufacturing process of T shape pick: after coming out with the high austenitic manganese steel casting of antifriction performance, car goes out axle (4) again, then axle (4) is inserted in the endoporus of electric tamper tamping rod (5) lower end, welded with electric welding again, as shown in Figure 1 and Figure 2.

Claims

1, being used for application number is T shape pick on 86107743 the electric tamper, it is characterized in that this be a kind of be the pick of T shape by widely different welding point of turning [3] with the planform that the knife plate [2] of bottom passes through formation mutually.

2, T shape pick according to claim 1, the thickness that it is characterized in that knife plate (2) is attenuation gradually from top to bottom, the shape of top edge is to the centre gradient that raises gradually to be arranged by two, and realizes that with the two sides of welding point (3) transition is connected with garden arc curve.

3, T shape pick according to claim 1 is characterized in that welding point (3) is that widely different turning is passed through with the knife plate (2) of bottom mutually with a little catotropic cone, and the upper end has axle (4).
