Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel castings, and more specifically, particularly relates to a corrosion-resistant steel casting. Background Art
[0002] Cast steel refers to steel specially used for manufacturing steel castings. Cast steel should be used when the strength requirements of castings are high and cast iron cannot meet the requirements. However, the fluidity of molten steel of cast steel is not as good as that of cast iron. Therefore, the thickness of the casting structure cannot be too small and the shape should not be too complicated. The fluidity of molten steel can be improved when the silicon content is controlled at the upper limit. Cast steel can be divided into general engineering cast steel, welded structure cast steel, stainless steel cast steel, and heat-resistant steel cast steel according to its type and use.
[0003] After long-term use or in a highly corrosive environment, steel castings are susceptible to corrosion at the locations where their surfaces come into contact with the air. Corrosion can cause damage to steel castings, which in turn creates safety hazards and increases production and maintenance costs. In addition, some steel castings used in large production sites such as factories are large in size and heavy in weight, and need to be moved and transported by hoisting. However, the hoisting method is easily limited by environmental factors and the location of the hoisting device, which affects the transportation efficiency of the steel castings.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a corrosion-resistant steel casting is provided to achieve a purpose with greater practical value. Utility Model Content

[0024] Example:
[0025] As attached Figure 1 To Attachment Figure 4 As shown:
[0026] The utility model provides a corrosion-resistant steel casting, comprising a steel casting body 1, a pair of mounting grooves 2 are symmetrically arranged on both sides of the top of the steel casting body 1, a pair of clamping grooves 3 are symmetrically arranged on both sides of the mounting groove 2, a protective shell 4 is sleeved on the top of the steel casting body 1, a pair of through grooves 5 are symmetrically arranged on both sides of the top of the protective shell 4, a pair of slide grooves 6 are symmetrically arranged on both sides of the through groove 5, a slider 7 is slidably installed in the slide groove 6, a pair of sliders 7 are installed with clamping blocks 8 at the bottom ends of the opposite sides, a limiting block 9 is installed at the middle position of the through groove 5, threaded holes 10 are arranged on both sides of the steel casting body 1 at positions close to the clamping grooves 3, and a pair of moving mechanisms are symmetrically installed on both sides of the bottom end of the steel casting body 1.
[0027] The protective shell 4 is adapted to the size of the steel casting body 1 , so that the protective shell 4 can be completely attached to the steel casting body 1 for protection, thereby improving the protection effect.
[0028] The clamping block 8 is connected with the clamping slot 3 by clamping, and the protective shell 4 is fixed on the steel casting body 1 by the clamping block 8 and the clamping slot 3 .
[0029] Among them, a pair of sliders 7 are equipped with pressing blocks 11 on the opposite sides of the top ends, and a pair of sliders 7 are symmetrically equipped with a plurality of springs 12 on the opposite sides, and one end of the spring 12 is connected to the limit block 9. The spring 12 pushes the slider 7 to reset and generates thrust to make the block 8 tightly stuck in the slot 3, thereby improving the stability of the protective shell 4.
[0030] Among them, the moving mechanism includes a pair of U-shaped frames 13, and the pair of U-shaped frames 13 are movably installed on both sides of the bottom end of the steel casting body 1. A pair of threaded holes 10 are penetrated on both sides of the U-shaped frame 13, and the threaded holes 10 are adapted to the positions and sizes of the threaded holes 10 on both sides of the steel casting body 1. A pair of universal wheels 14 are symmetrically installed on both sides of the bottom end of the U-shaped frame 13. By aligning the threaded holes 10 on the U-shaped frame 13 and the threaded holes 10 on the steel casting body 1, the bolts can enter the two threaded holes 10 in turn, thereby fixing the U-shaped frame 13 on the steel casting body 1, and improving the transportation efficiency of the steel casting body 1 through the universal wheels 14.
[0031] The bottom of the protective shell 4 is provided with a protective layer 15 at a position where it fits the steel casting body 1 , and the surface of the steel casting body 1 is provided with a corrosion-resistant galvanized layer to improve the protection of the steel casting body 1 .
[0032] The working principle of this embodiment is as follows: when it is necessary to transport the steel casting, the staff first lifts the steel casting to a certain height, and adjusts the position of the U-shaped frame 13 so that the threaded holes 10 on the U-shaped frame 13 are aligned with the threaded holes 10 on both sides of the steel casting, and the bolts are passed through the two threaded holes 10 in sequence, so that the two U-shaped frames 13 are fixed to the steel casting. At this time, the steel casting body 1 is pushed, and the steel casting body 1 is driven to move to the designated position through the universal wheel 14, thereby improving the transportation efficiency of the steel casting. After the steel casting is installed at the designated position, the bolts are taken out. The U-shaped frame 13 can be removed by the bolt. When installing the protective shell 4, the staff first squeezes the pressing plate to make a pair of sliders 7 move relative to each other in the slide groove 6, driving a pair of clamping blocks 8 to move relative to each other, and clamping a pair of clamping blocks 8 into the clamping grooves 3 on both sides of the installation groove 2. At this time, the spring 12 generates a thrust on the slider 7, so that the clamping block 8 is tightly clamped in the clamping groove 3 to fix the protective shell 4. When the protective shell 4 is corroded after being used for a period of time, the pressing block 11 is squeezed to make the clamping block 8 detach from the clamping groove 3, and the protective shell 4 can be disassembled and replaced by moving the protective shell 4.
