This arc convex block exactly matches the recessed arc concave hole of the second die stock, ensuring that they do not rotate relative to each other during use and having uniqueness during placement to prevent errors.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] In the present utility model, the outer surface of the force - adding rod is made of steel, which has high strength and good corrosion resistance. It is located at the upper part of the tool and is connected to the die stock sleeve through the rod hole above the die stock sleeve, facilitating hand - holding and playing a role in adding force during operation. The lower part of the die stock sleeve is a round hole, and the first die stock and the second die stock can be placed inside. There is a step designed above the round hole at the lower part of the die stock sleeve to prevent the first die stock and the second die stock from being inserted too deeply and being inconvenient to take out when placed. A protruding arc convex block is designed in the round hole at the lower part of the die stock sleeve. This arc convex block exactly matches the recessed arc concave hole of the second die stock, ensuring that they do not rotate relative to each other during use and having uniqueness during placement to prevent errors.

[0018] In the present utility model, the first die stock and the second die stock are made of high - hardness alloy steel. The inside has internal threads that match the studs, and the thread edges of the internal threads are relatively sharp. The pitch major diameter is larger than the major diameter of the bolt, which can play a role in repairing the bolt. Round holes are distributed on the outer circle of the internal threads, and these round holes are chip - discharging holes to prevent iron chips from not being discharged during the repair of the studs and squeezing the threads. There is a protruding triangular convex platform at the upper middle part on the right plane of the first die stock, and a recessed triangular concave platform at the upper middle part on the left plane of the second die stock. The triangular convex platform of the first die stock and the triangular concave platform of the second die stock match each other to ensure the accuracy of thread positioning, and the convex platform and the concave platform are located at the upper middle part of the plane, so as to ensure the uniqueness of positioning and prevent errors.

[0025] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0026] Embodiment:

[0027] Please refer to Figures 1-4 , A track station pile thread repair device in this embodiment includes a main body mechanism 1. A chip - removal mechanism 2 is arranged at the bottom of the main body mechanism 1, and a repair mechanism 3 is arranged at the bottom of the main body mechanism 1;

[0028] The main body mechanism 1 includes a die sleeve 101. A rod hole 102 is opened on the surface of the die sleeve 101. A round hole 103 is opened at the bottom of the die sleeve 101. An arc convex block 104 is fixedly connected to the inner wall of the round hole 103. A force - adding rod 105 is inserted into the inner wall of the rod hole 102. The outer surface of the force - adding rod 105 is made of steel, with high strength and good corrosion resistance. It is located at the upper part of this tool and is connected to the die sleeve 101 through the round hole 103 above the die sleeve 101, facilitating hand - holding and playing a role in adding force during operation. The outer surface of the force - adding rod 105 is made of steel.

[0029] The chip - removal mechanism 2 includes a first die 201. The first die 201 is sleeved inside the round hole 103. A triangular convex platform 202 is fixedly connected to the right side of the first die 201. A chip - removal hole 203 is opened at the top of the first die 201. Below the die sleeve 101 is the round hole 103, which can place the first die 201 and the second die 301 inside. And there is a step designed above the round hole 103 at the bottom of the die sleeve 101 to prevent the first die 201# and the second die 301# from being inserted too deeply and being inconvenient to take out when placed.

[0030] The repair mechanism 3 comprises a second die 301 , which is sleeved in the circular hole 103 . A triangular concave platform 302 is provided on the left side of the second die 301 , and an arc concave hole 303 is provided on the top of the second die 301 .

[0031] The position and shape of the triangular concave platform 302 correspond to the position and shape of the triangular convex platform 202. The first die 201 has a protruding triangular convex platform 202 in the upper middle part of the right side, and the second die 301 has a recessed triangular concave platform 302 in the upper middle part of the left side plane. The triangular convex platform 202 of the first die 201 and the triangular concave platform 302 of the second die 301 match each other to ensure the accuracy of thread positioning.

[0032] The position and shape of the arc protrusion 104 correspond to the position and shape of the arc recessed hole 303. The circular hole 103 below the die sleeve 101 is designed with a protruding arc protrusion 104. This arc protrusion 104 and the arc recessed hole 303 of the second die 301 match exactly to ensure that they do not rotate with each other during use, and are unique when placed to prevent errors.

[0033] The implementation principle of a rail pile thread repair device in the embodiment of the present application is as follows: when using a special tool for quickly repairing a station bolt, the rail pile thread repair device first finds a part of the station bolt with a length of about 20 mm that is not damaged or has a light damage, and fits the first die 201 of the tool tightly with the thread of the station bolt, and then aligns the second die 301 with the positioning table and fits it tightly with the first die 201 (there is a thread on the contact surface between the die and the bolt, and the worker will not fall off even if he does not press the die), and then inserts the first die 201 and the second die 301 into the die sleeve 101. The circular hole 103 below the tooth sleeve 101 needs to be inserted into the circular hole 103, and the arc protrusion 104 and the arc concave hole 303 that are positioned with each other need to be aligned. After insertion, the die sleeve 101 is rotated by the force rod 105, and the die sleeve 101 drives the first die 201 and the second die 301 to rotate upward or downward to repair the damaged standing bolt thread. After the repair is completed, the force rod 105 is held and lifted upward, and the force rod 105 drives the die sleeve 101 to move upward, and the sleeve is separated from the first die 201 and the second die 301, and finally the first die 201 and the second die 301 are removed.

[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
