Description

Technical Field

[0001] The utility model relates to the technical field of railway engineering construction, in particular to a fixing device for alloy co-penetration of embedded parts of a high-speed railway box beam. Background Art

[0002] Alloy co-penetration is an advanced metal surface treatment technology, mainly used to improve the performance of metals. Under high temperature and high pressure conditions, chemical substances containing multiple metal elements are heated together with the metal surface, so that the elements on the metal surface and in the chemical substances diffuse into each other to form an alloy layer.

[0003] The embedded parts of the high-speed railway box girder are formed by stacking multiple embedded steel plates together, and the embedded steel plates are all treated with anti-corrosion on the outer surface using this process; but when treating the embedded steel plates with anti-corrosion, it is first necessary to stack multiple embedded steel plates together, and then pass steel bars through the through holes on the corners of the embedded steel plates to fix the stacked embedded steel plates, and then place spacers between adjacent embedded steel plates to separate the embedded steel plates, and finally coat the surface of the embedded steel plates; during the coating process of the embedded steel plates, the upper and lower end surfaces of the spacers used are in direct contact with the embedded steel plates, and the contact position cannot contact with the alloy powder, and the through holes on the embedded steel plates are penetrated by steel bars, resulting in the inner wall of the through holes also unable to contact with the gold powder, and subsequent paint repair is required for process anti-corrosion, which affects the work efficiency of the construction personnel and the quality of the physical project. Utility Model Content

[0004] The utility model provides a fixing device for alloy co-penetration of embedded parts of a high-speed railway box beam, which can overcome the defects of the prior art.

[0005] According to the utility model, a fixing device for alloy co-diffusion of embedded parts of a high-speed railway box beam comprises: a gasket body, the gasket body comprises a connecting portion arranged between adjacent embedded steel plates, and an inserting portion extending into a through hole on the embedded steel plate; the inserting portion is conical in shape; a mounting hole passing through the connecting portion and the inserting portion is arranged inside the gasket body; a plurality of feed ports distributed along the circumference of the inserting portion and communicating with the mounting holes are arranged at the inserting portion.

[0006] According to the utility model, before the embedded parts of the high-speed railway box beam are plated, the staff stacks the embedded steel plates together and places the gasket body between the adjacent embedded steel plates, so that the insertion part on the gasket body extends into the through hole on the embedded steel plate, and the bottom of the insertion part is located outside the through hole; during the plating process, the upper and lower end surfaces of the gasket body do not contact the embedded steel plates, so that the embedded steel plates can be fully in contact with the alloy powder, thereby preventing uneven plating on the surface of the embedded steel plates and avoiding the need for the staff to repaint the embedded steel plates later;

[0007] During the coating process, the alloy powder can enter the through hole on the embedded steel plate from the feed port, so that the alloy powder can contact the inner wall of the through hole, thereby fitting on the inner wall of the embedded steel plate, preventing the inner wall of the through hole on the embedded steel plate from being unable to contact the alloy powder, thereby affecting the alloy co-galvanizing effect;

[0008] Since the inserting portion is tapered, it only contacts the edge of the through hole on the embedded steel plate, and does not affect the alloy co-penetration effect.

[0009] Preferably, the outer wall of one end of the insertion portion away from the connection portion expands outwardly in the circumferential direction to form a flange; the flange is clearance-matched with the inner wall of the through hole on the embedded steel plate.

[0010] Through the utility model, when the staff stacks the embedded steel plates, the insertion part on the gasket body is inserted into the through hole on the embedded steel plate. At this time, the flange on the insertion part will abut against the through hole on the embedded steel plate, thereby preventing the insertion part from shaking in the through hole, thereby preventing the embedded steel plate from moving and scratching and damaging the alloy layer on its outer surface.

[0011] Preferably, a threaded rod passing through the mounting hole and the through hole on the embedded steel plate is provided at the embedded steel plate, and nuts are provided at both ends of the threaded rod.

[0012] According to the utility model, after the staff stacks the embedded steel plates, the threaded rod is passed through the mounting holes on all the embedded steel plates and the gasket body, and then the nut is screwed on the threaded rod, and the nut is pressed against the embedded steel plates, so that the staff can fix the stacked embedded steel plates conveniently;

[0013] The flange can also keep the gasket body stable, making it convenient for workers to pass the threaded rod through the mounting hole on the gasket body so that the threaded rod can pass smoothly from top to bottom, avoiding the need for workers to adjust the position of the embedded steel plate, saving construction time and improving construction efficiency.

[0014] Preferably, a gasket is provided between the nut and the embedded steel plate.

[0015] With the utility model, the gasket is located between the nut and the embedded steel plate, preventing the nut from directly contacting the embedded steel plate. At the same time, the gasket increases the contact area with the embedded steel plate, thereby preventing the embedded steel plate from being squeezed and deformed when the nut squeezes the embedded steel plate.

[0016] Preferably, the length of the insertion portion extending into the through hole on the embedded part steel plate is less than half the length of the through hole.

[0017] Through the utility model, when the staff stacks the embedded steel plates, the two gasket bodies are respectively located on the upper and lower sides of the through hole on one of the embedded steel plates, and the length of the insertion part of the gasket body extending into the through hole is less than half of the length of the through hole, thereby preventing the gasket bodies located on the upper and lower sides of the through hole from influencing each other, thereby causing the embedded steel plates to be stacked unstable.

[0018] Preferably, the gasket body is made of stainless steel.

[0019] Through the utility model, the stainless steel structure has a relatively strong strength, thereby preventing the gasket body from being squeezed and deformed between the embedded steel plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] During the coating process, the alloy powder can enter the through hole on the embedded steel plate from the feed port 6, so that the alloy powder can contact the inner wall of the through hole, thereby fitting on the inner wall of the embedded steel plate, preventing the inner wall of the through hole on the embedded steel plate from being unable to contact the alloy powder, thereby affecting the alloy co-galvanizing effect;

[0031] Through this embodiment, when the staff stacks the embedded steel plates, the insertion part 8 on the gasket body 3 is inserted into the through hole on the embedded steel plate. At this time, the flange 7 on the insertion part 8 will abut against the through hole on the embedded steel plate, thereby preventing the insertion part 8 from shaking in the through hole, thereby preventing the embedded steel plate from moving and scratching and damaging the alloy layer on its outer surface.

At the same time, the gasket 2 increases the contact area with the embedded steel plate 4, thereby preventing the embedded steel plate 4 from being squeezed and deformed when the nut 1 squeezes the embedded steel plate 4.
