DETAILED DESCRIPTION

[0035] In order to more clearly illustrate the technical scheme of the embodiments of the utility model, the following will be briefly introduced the drawings needed to be used in the embodiments, obviously, the drawings in the following description are some embodiments of the utility model, and for those skilled in the art, other drawings can also be obtained according to these drawings without creating creative labor.

[0036] Referring to Figure 1 , Figure 2 The utility model embodiment provides a kind of slag car 10 for laser cutting machine, including car body 11, wheel 12, pull rod 13, bottom plate 15, partition plate 16, lap plate 17, car body 11 is a rectangular frame, car body 11 includes longitudinal fender 111, transverse fender 112, wheel 12 is located at the bottom of longitudinal fender 111, pull rod 13 is located at the outside of one side transverse fender 112, two longitudinal fenders 111 are fixedly connected with partition plate 16, one bottom plate 15 is arranged at the two sides of partition plate 16, one side of bottom plate 15 is connected with one side of lap plate 17, another side of lap plate 17 is overlapped on one longitudinal fender 111, and bottom plate 15 does not contact with partition plate 16 and transverse fender 112.

[0037] Exemplarily, pull rod 13 is rotatably connected with transverse fender 112, and the connecting structure of pull rod 13 and transverse fender 112 adopts conventional design, which is not limited.

[0038] Exemplarily, one end of partition plate 16 is fixedly connected with the inner side wall of one longitudinal fender 111, and the other end of partition plate 16 is fixedly connected with the inner side wall of another longitudinal fender 111, and the fixed connection can adopt welding, to divide the inner cavity of rectangular frame into two smaller inner cavities.

[0039] Exemplary, the heat insulation plate is made of fireproof cotton or thermal cotton, which is arranged between the lap plate 17 and the longitudinal fender 111 to reduce the heat transferred from the bottom plate 15 to the vehicle body 11. The bottom plate 15 is not connected with the longitudinal fender 111, and the deformation of the bottom plate 15 will not cause the deformation of the vehicle body 11. The lap plate 17 is made of two metal materials with different expansion coefficients, which are adhered to each other. After being heated, the lap plate 17 will bend. In the case where the heat insulation plate is not arranged, the lap plate 17 can prevent the adhesion between the lap plate 17 and the longitudinal fender 111.

[0040] Referring to Figures 1 to 6 In the first modified structure of the prior design of the molten slag car 10, that is, the structure of the present application, the bottom plate 15 is cut, and the cut bottom plate 15 is cut into two pieces. Each side of the bottom plate 15 is welded with the lap plate 17 and the partition plate 16. The bottom plate 15 on both sides of the partition plate 16 is connected between the two longitudinal fenders 111 through the lap plate 17. The connection can be understood as the contact between the lap plate 17 and the longitudinal fender 111 without connection.

[0041] Beneficial effects: The partition plate 16 is arranged between the two longitudinal fenders 111 to strengthen the heat deformation resistance of the vehicle body 11. The bottom plate 15 is connected with the longitudinal fender 111 through the lap plate 17, and is not connected with the partition plate 16 and the transverse fender 112. The deformation of the bottom plate 15 will not cause the deformation of the vehicle body 11, effectively weakening the main influencing factor of the deformation of the vehicle body 11.

[0042] Referring to Figures 7 to 10 In the second modified structure of the prior design of the molten slag car 10, the partition plate 16 is not arranged. The bottom plate 15 is not cut into two pieces. Only the bottom plate 15 is cut, and the support rib 14 is welded. The bottom plate 15 is arranged on the support rib 14. The first gap and the second gap are cut to make the bottom plate 15 not connected with the longitudinal fender 111 and the transverse fender 112. A plurality of support ribs 14 are connected between the two longitudinal fenders 111. The bottom plate 15 is movably arranged on the upper surface of the support rib 14. The bottom plate 15 is not connected with the longitudinal fender 111 and the transverse fender 112. The movable arrangement means that the bottom plate 15 is connected with the support rib 14 without connection. The support rib 14 is vertically arranged. The contact area between the upper surface of the support rib 14 and the lower surface of the bottom plate 15 is small. The side of the support rib 14 connected with the bottom plate 15 can be designed as a toothed shape. The upper surface of the support rib 14 is connected with the lower surface of the longitudinal fender 111. The support rib 14 is uniformly distributed along the length direction of the longitudinal fender 111. The support rib 14 is parallel to the transverse fender 112. The molten slag falls on the bottom plate 15. The heat carried by the molten slag is transferred to the bottom plate 15. The bottom plate 15 is connected with the vehicle body 11 through the support rib 14. The heat transferred to the vehicle body 11 is small, which prevents the deformation of the vehicle body 11. The bottom plate 15 is not connected with the vehicle body 11. The deformation of the bottom plate 15 will not cause the deformation of the vehicle body 11, effectively weakening the main influencing factor of the deformation of the vehicle body 11.

[0043] Referring to Figure 1 , Figure 2 Further, the cross section of the lap plate 17 is "L" shaped.

[0044] For example, any one of the bottom plates 15 is clamped with the corresponding one of the longitudinal side edges 111 by two clamping plates 17, and preferably, there is a gap between the bottom plate 15 and the partition plate 16 and the horizontal side edge 112.

When the force direction of the vehicle body 11 changes, the second rotation axis will automatically adjust the direction. Compared with the case that the wheel frame 121 is fixedly connected with the longitudinal side edge 111, when the wheel hub 122 is subjected to excessive force, it is difficult for the second rotation axis to adjust the direction, and the slag car 10 is difficult to pull.
