Description

Technical Field

[0001] The utility model relates to a load-bearing resistant ground structure for special places, and more specifically, it relates to a wear-resistant ground of a slag outlet of a slag box. Background Art

[0002] The ground at the slag outlet of the slag box in the hot pouring room of the slag plant is frequently affected by factors such as friction and shearing of excavator tracks and forklift sprockets (tires wrapped with steel chains) and rolling of heavy transport vehicles, which causes the ground to be easily damaged, with cracks, breakages, missing parts, and uneven conditions. The uneven ground not only affects the operating efficiency of machinery and vehicles, but also makes it easy for excavators, forklifts, and automobiles to roll over during transportation operations, posing a major safety hazard. If the ground is repaired and restored, the construction and maintenance time will not only be long, delaying normal slag discharge and affecting the normal turnover of the slag box, but because its basic structure has not changed, it will also cause the road surface to be easily damaged again, and the maintenance cost will be high. Utility Model Content

[0005] As a further improvement, the width of the second steel plate is greater than the width of the third steel plate, and the width of the third steel plate is greater than the width of the first steel plate.

[0016] The utility model is further described below in conjunction with the embodiments, but does not constitute any limitation to the utility model. Any limited modifications made by anyone within the scope of the claims of the utility model are still within the scope of the claims of the utility model.

[0017] See also Figure 1-Figure 3The utility model discloses a wear-resistant floor surface for a slag box outlet, comprising a concrete layer 1. A steel cage 2 is embedded in the concrete layer 1, and a plurality of first steel plates 6 are fixed at the upper edge of the steel cage 2 to form an edge welding strip 3. Among them, the first steel plate 6 is welded above the steel bars at the edge of the steel cage 2, and its width is the smallest and only slightly larger than the diameter of the steel bars, and is used as a reference for positioning the edge. Two middle welding strips 4 are provided at the upper middle position of the steel cage 2, and each middle welding strip 4 is composed of three second steel plates 7. Among them, the second steel plate 7 is overlapped and welded to the three steel bars on the steel cage 2, and its width is larger than the first steel plate 6 and the third steel plate 8, and is used for middle support. A bottom edge welding strip 5 composed of six third steel plates 8 is provided between two adjacent middle welding strips 4, which is used to weld and position the bottom edge of the fourth steel plate 9. At the same time, it plays a role in supporting the two adjacent fourth steel plates 9 in front of different slag boxes, so that the fourth steel plates 9 in front of all slag boxes are connected as one, which greatly improves the support capacity of the ground. The third steel plate 8 is overlapped and welded to two steel bars on the steel cage 2 , and its width is greater than that of the first steel plate 6 .

[0018] The upper end surfaces of the edge welding strip 3, the middle welding strip 4 and the bottom edge welding strip 5 are all flush with the surface of the concrete layer 1 to ensure that after the fourth steel plate 9 is welded with the first steel plate 6, the second steel plate 7 and the third steel plate 8, it can simultaneously contact the first steel plate 6, the second steel plate 7, the third steel plate 8 and the concrete layer 1, avoiding the phenomenon of hollowing, which is conducive to improving the ground support force. Three fourth steel plates 9 are welded and fixed between the edge welding strip 3, the middle welding strip 4 and the bottom edge welding strip 5, that is, three fourth steel plates 9 are laid on the ground in front of each slag box as the contact surface with the walking part of the mechanical equipment. The fourth steel plate 9 is a 30mm thick steel plate. The wear resistance of the steel plate greatly improves the wear resistance of the ground in front of the slag box. Moreover, in this embodiment, the fourth steel plate 9 serving as the ground surface is welded and fixed by means of the steel cage 2 pre-buried in the concrete layer 1 and the three sizes of steel plates welded on the top of the steel cage 2, thereby ensuring that the ground effectively supports the movement of the machinery and improving the wear resistance of the ground, thereby solving the problem in the prior art that the ground is easily crushed and sunken by the machinery.

[0019] In order to increase the friction of the contact surface of the walking part of the mechanical equipment and prevent the machine from slipping, grid grooves are opened on the surface of the fourth steel plate 9 to increase the surface roughness of the fourth steel plate 9.

[0020] An operating gap 10 is provided between two adjacent third steel plates 8, and its function is to facilitate the welding of the fourth steel plate 9 to the third steel plate 8. However, the spacing of the operating gap 10 is larger than the slot width of the grid slot, so it needs to be filled, otherwise it is easy to cause the crawler track of the machine to get stuck in the operating gap 10. Therefore, a filling piece 11 is fixedly provided in the operating gap 10 of this embodiment. Specifically, the filling piece 11 is made of semi-circular steel, that is, the round steel is cut in the middle and divided into two symmetrical parts. The cross-section of the semi-circular steel is flush with the surface of the fourth steel plate 9 to ensure the flatness of the ground. The semi-circular steel is welded to the third steel plate 8, and the weld needs to be polished and smoothed after welding.

[0021] The working principle of the utility model is: when constructing the wear-resistant floor, the original damaged floor and its foundation should be cleared first, and then the steel cage 2 is placed in the foundation pit of the ground or tied therein. After the steel cage 2 is constructed, the first steel plate 6, the second steel plate 7 and the third steel plate 8 are respectively welded on the edge, the middle part and the position corresponding to the adjacent parts of the two slag boxes of the steel cage 2. After welding, concrete can be cast in the foundation pit, and the ground foundation can be obtained after the concrete solidifies, and the surfaces of the first steel plate 6, the second steel plate 7 and the third steel plate 8 at this time are flush with the surface of the concrete layer 1. Then the fourth steel plate 9 is placed on the surface of the concrete layer 1, and the steel plate on the surface of the concrete layer 1 is partially exposed to facilitate welding. After the fourth steel plate 9 is placed, the fourth steel plate 9 can be welded. After the fourth steel plate 9 is welded, take a semicircular steel with a diameter consistent with the operating gap 10, place its semicircular part in the operating gap 10, and the surface is flush with the surface of the third steel plate 8, and then weld and grind the weld to make it flat.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
