Description

TECHNICAL FIELD

[0001] The application relates to a demolding technology for a ballast retaining plate, in particular to a rapid auxiliary L-shaped ballast retaining plate prefabrication demolding tool. BACKGROUND

[0002] With the popular use of large machines for screening on railway bridge lines, the operation efficiency is greatly improved. Since the ballast retaining wall is provided on the railway bridge to prevent the ballast of the track bed from scattering and to ensure the stability of the track bed, the ballast retaining wall is damaged to a certain extent during the large machine screening process, thereby causing problems such as the tilting and breaking of the ballast retaining plate. Therefore, a large number of L-shaped ballast retaining plates need to be prefabricated and replaced. Since the shape of the L-shaped ballast retaining plate is special, it is difficult to demold after the mold is prefabricated. Therefore, a rapid auxiliary L-shaped ballast retaining plate prefabrication demolding tool is developed to improve the prefabrication efficiency of the L-shaped ballast retaining plate.

[0003] In view of this, a rapid auxiliary L-shaped ballast retaining plate prefabrication demolding tool is provided. CONTENT OF THE INVENTION

[0008] By adopting the above technical scheme, the first handle is rotatably connected to the opening side of the first U-shaped frame, the second handle is rotatably connected to the opening side of the second U-shaped frame, and the "mouth" type structure formed by the first U-shaped frame and the second U-shaped frame has an outer dimension greater than that of the mold flange. Therefore, the mold flange is placed into the opening formed by the first U-shaped frame and the second U-shaped frame, two workers pull the first U-shaped frame and the second U-shaped frame away from each other, so that one side edge of the first U-shaped frame and the second U-shaped frame is clamped on the mold and is clamped at the lower edge of the mold flange. Then, the mold is turned over in the same direction by one hundred and eighty degrees, so that the opening faces downward, and the demolding can be quickly performed.

[0009] As an optional solution of the technical scheme in the application file, the first U-shaped frame comprises a first horizontal rod and sleeves fixed vertically at both ends of the first horizontal rod, the second U-shaped frame comprises a second horizontal rod and insertion rods fixed vertically at both ends of the second horizontal rod, the sleeves are provided with mounting holes matched with the insertion rods, the first handle and the second handle each comprise two parallel traction rods and shaft rods fixed at one end of the traction rods, one end of the sleeve close to the second horizontal rod is rotationally connected with the traction rods through the shaft rods, one end of the insertion rods close to the first horizontal rod is rotationally connected with the traction rods through the shaft rods, and a handle is fixedly and perpendicularly connected between the two traction rods.

[0011] As an optional solution of the technical scheme in the application file, the handle is sleeved with a sleeve.

[0012] By adopting the above technical scheme, the sleeve is rotated on the handle to avoid friction when the handle and the palm are rotated.

[0013] As an optional solution of the technical scheme in the application file, the first horizontal rod and the second horizontal rod are each fixed with an L-shaped plate.

[0014] By adopting the above technical scheme, when the first horizontal rod and the second horizontal rod are placed below the flange of the mold, the upper edge of the L-shaped plate is blocked on the upper surface of the flange of the mold, so that when the mold is slid and abuts against the L-shaped plate during the whole turning of the mold, the mold can be prevented from falling off the demolding tool.

[0015] As an optional solution of the technical scheme in the application file, a spring is fixed between the second horizontal rod and the sleeve.

[0016] By adopting the above technical scheme, when the first horizontal rod and the second horizontal rod move relatively, the spring is compressed to generate an elastic rebounding force, so that when the demolding tool is removed from the mold, the handle is loosened, the first horizontal rod and the second horizontal rod are separated under the elastic rebounding force of the spring, and the demolding tool is quickly removed from the mold.
