Referring to fig. 1 to 3, the utility model provides a self-collision type long steel rail stress spreader, which comprises a gasoline engine 1, a hydraulic reversing valve 2, an energy accumulator 3, a collision component 4, a spreading collision plate 5, a buffer spring 6 and a control system.
The gasoline engine 1 can drive the gasoline engine 1 to drive the hydraulic oil pump 7 to act by filling gasoline.
Specifically, the gasoline engine 1 is connected to the hydraulic oil pump 7 by a belt so that the hydraulic oil pump 7 can send hydraulic oil to the hydraulic directional valve 2 through an oil feed line 71 and can return the hydraulic oil at the hydraulic directional valve 2 to the hydraulic oil pump 7 through an oil return line 72.

The energy accumulator 3 can provide power for striking the striking assembly 4, and the interior of the energy accumulator 3 is formed into two parts by the piston 31, wherein one part is an air cavity 32, and the other part is an oil cavity 33. When hydraulic oil is injected into the oil cavity 33, the piston 31 moves towards the air cavity 32 to compress the air cavity 32, and the air cavity 32 can form a reaction force after being compressed so as to push the piston 31 to move towards the oil cavity 33, the hydraulic oil in the oil cavity 33 can generate impact force on the impact assembly 4, and the impact assembly 4 can generate impact force after being subjected to the impact force of the hydraulic oil, namely, the impact assembly 4 is pushed.
A hydraulic pressure sensor 34 is provided in the oil chamber 33, the hydraulic pressure sensor 34 is connected to the control system, and the hydraulic pressure sensor 34 transmits the pressure in the oil chamber 33 to the control system.

For example, when the pressure sensor 34 senses that the pressure of the hydraulic oil in the oil chamber 33 is smaller than the set threshold value, the hydraulic oil pump 7 can be controlled to continue to deliver the hydraulic oil into the oil chamber 33 through the hydraulic directional valve 2, and when the pressure sensor 34 reaches the set threshold value, the pressure in the air chamber 32 can be judged to be operable. At this time, the control system can control the energy accumulator 3 to release the pressure in the air cavity 32, and the release mode can be a conventional control switch, which belongs to the conventional control switch.
After the air cavity 32 in the energy accumulator 3 releases pressure, the control system controls the hydraulic reversing valve 2 to reverse, the hydraulic oil pump 7 sucks hydraulic oil out of the oil cavity 33 through the hydraulic reversing valve 2, and the above actions are repeated, so that the reciprocating impact of the impact assembly 4 is realized.

The striking rod 41 is partially inserted into the oil chamber 33, and a corresponding sealing structure is arranged at the edge of the part of the end surface inserted into the oil chamber 33, so that on one hand, the hydraulic oil impact force in the oil chamber 33 fully acts on the end surface of the striking rod 41, and on the other hand, the hydraulic oil is prevented from flowing out. It can be understood that the sealing structure can prevent hydraulic oil from flowing out, and the corresponding sealing structure can be selected according to actual conditions.
An impact head 42 is sleeved at one end of the impact rod 41 away from the oil cavity 33. Since the impact head 42 is a consumable, the impact head 42 is replaced with the impact rod 41, and when the impact head 42 is damaged, the impact head 42 can be directly replaced.
In addition, in order to fix the impact head 42 to the impact rod 41, a sleeved method is adopted, and a threaded connection method is not adopted, and the impact head 42 is deformed during impact, so that the threaded structure brings inconvenience to the process of detaching the impact head 42.
