Description

Technical Field

[0001] The utility model relates to the technical field of single prop manufacturing, and particularly relates to a single prop sealing surface coating device. Background Art

[0002] The plunger suspension type single hydraulic prop has been widely used in underground coal mines because of its advantages such as the plunger type sealing principle, large stroke and high strength. Since the surface of the moving column of the single hydraulic prop is chemically nickel-plated or chromium-plated, the coating on the surface of the moving column is corroded and peeled off due to the handling, dropping and bumping during the use of the single hydraulic prop. And the acidic and corrosive environment in underground coal mines is likely to cause the premature failure and leakage of the sealing part, resulting in a greatly shortened service life of the single hydraulic prop, a relatively high repair rate, and an increase in the cost of users.

[0003] In view of the above problems, in the prior art, a stainless steel sleeve with very good corrosion resistance and high hardness is coated on the surface of the moving column body. Since stainless steel has strong corrosion resistance, coating the stainless steel sleeve on the surface of the moving column will greatly enhance the corrosion resistance of the prop and improve the service life of the prop.

[0004] When coating the stainless steel sleeve on the single prop, a relatively large pressure is required for pressing in. At the same time, it is not easy to align coaxially during pressing in, and problems such as non-coincidence of the axis are likely to occur. And the existing coating device cannot be applied to the sealing operations of single props of various specifications. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a single prop sealing surface coating device, which is convenient for coaxially aligning the stainless steel sleeve with the single prop and can be applied to the sealing operations of single props of different specifications.

[0006] The utility model provides a single prop sealing surface coating device, which comprises a pressing mechanism, a guiding mechanism and a coating mechanism, wherein:

[0007] The pressing mechanism comprises a pressing base. One side of the pressing base is provided with a hydraulic cylinder. The end of the hydraulic cylinder is provided with a positioning seat.

[0017] Preferably, a rotating handle is arranged on one side of the adjusting screw rod.

[0018] The working principle of the present utility model: For the single prop seal breading device of the present utility model, during use, the stainless steel sleeve is assembled in a mold matching its outer diameter and placed in the mold mounting hole 34 on the coating bracket. Then, one end of the single prop is positioned by the positioning column, and the other end is aligned with the stainless steel sleeve. The hydraulic cylinder is started, and the single prop is pressed into the stainless steel sleeve through the pressure of the hydraulic cylinder to complete the coating. Finally, the coated single prop is conveyed out of the device by the conveying mechanism.
