DETAILED DESCRIPTION

[0035] In order to more clearly illustrate the technical scheme of the embodiments of the present application, the drawings needed in the embodiments will be briefly introduced as follows. Obviously, the drawings described in the following are some embodiments of the present application, and other drawings can also be obtained by those skilled in the art without any creative effort on the basis of these drawings.

[0036] Referring to Figures 1 to 4 The anti-deformation molten slag vehicle 10 provided by the embodiments of the present application comprises a vehicle body 11, a wheel 12, a pull rod 13, a support rib 14 and a bottom plate 15. The vehicle body 11 is a rectangular frame, and comprises a longitudinal baffle 111 and a horizontal baffle 112. The wheel 12 is arranged at the bottom of the longitudinal baffle 111, and the pull rod 13 is arranged outside one side of the horizontal baffle 112. A plurality of support ribs 14 are arranged between the two longitudinal baffles 111 in a lapping manner. The bottom plate 15 is movably arranged on the upper surface of the support rib 14, and the bottom plate 15 does not contact the longitudinal baffle 111 and the horizontal baffle 112.

[0037] The movable arrangement means that the bottom plate 15 contacts the support rib 14 but is not connected to the support rib 14.

[0038] For example, the pull rod 13 is rotationally connected to the horizontal baffle 112, and the connection structure of the pull rod 13 and the horizontal baffle 112 is not limited.

[0039] For example, 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, and the side of the support rib 14 contacting the bottom plate 15 can be designed to be toothed. The upper surface of the support rib 14 is connected to the lower surface of the longitudinal baffle 111, the support rib 14 is uniformly distributed along the length direction of the longitudinal baffle 111, and the support rib 14 is parallel to the horizontal baffle 112.

[0040] Beneficial effects: The molten slag falls on the bottom plate 15, and the heat carried by the molten slag is transferred to the bottom plate 15. The bottom plate 15 is connected to the vehicle body 11 through the support rib 14, so that less heat is transferred to the vehicle body 11, and the deformation of the vehicle body 11 is prevented. The bottom plate 15 does not contact the vehicle body 11, so that the deformation of the vehicle body 11 caused by the deformation of the bottom plate 15 is effectively weakened.

[0041] Referring to Figures 1 to 4 Further, the upper surface of the longitudinal baffle 111 is an inclined surface.

[0042] For example, the longitudinal baffle 111 is formed by bending a plate, the cross section of the longitudinal baffle 111 is a right trapezoid, the horizontal baffle 112 is a vertically arranged plate, and the longitudinal baffle 111 and the horizontal baffle 112 are welded into one body.

[0043] Referring to Figures 1 to 4Further, the wheel 12 comprises a wheel frame 121 and a wheel hub 122, the wheel hub 122 is rotationally connected with the wheel frame 121, and the wheel frame 121 is fixedly connected with the longitudinal fender 111.

[0044] In one embodiment, the wheel frame 121 is rotationally connected with the longitudinal fender 111, the rotation axis of the wheel frame 121 and the longitudinal fender 111 is the first rotation axis, the rotation axis of the wheel frame 121 and the wheel hub 122 is the second rotation axis, the first rotation axis is perpendicular to the second rotation axis, and the first rotation axis is not coplanar with the second rotation axis. When the force direction of the vehicle body 11 changes, the second rotation axis will adjust the direction by itself. Compared with the case that the wheel frame 121 is fixedly connected with the longitudinal fender 111, when the wheel hub 122 is subjected to excessive force, the second rotation axis is difficult to adjust the direction, and the slag car 10 is difficult to pull.

[0045] Referring to Figures 1 to 4 Further, the first gap is arranged between the bottom plate 15 and the longitudinal fender 111, and the second gap is arranged between the bottom plate 15 and the transverse fender 112.

[0046] Referring to Figures 5 to 8 The slag car 10 designed by the applicant previously is different from the present application in that: first, no supporting rib 14 is arranged; and second, the bottom plate 15 is connected with the longitudinal fender 111 and the transverse fender 112 integrally. When the slag falls on the bottom plate 15, the heat is transferred to the vehicle body 11 through the bottom plate 15, which aggravates the thermal deformation of the vehicle body 11, and the deformation of the bottom plate 15 also involves the deformation of the vehicle body 11.

[0047] Referring to Figures 1 to 4 The first modified structure of the slag car 10 designed previously, i.e. the structure of the present application, only needs to cut the bottom plate 15, weld the supporting rib 14, place the bottom plate 15 on the supporting rib 14, cut the first gap and the second gap, and make the bottom plate 15 not contact with the longitudinal fender 111 and the transverse fender 112.

[0048] Referring to Figures 9 to 10 The second modified structure of the slag car 10 designed previously does not arrange the supporting rib 14, but welds the partition plate 16 between the two longitudinal fenders 111, cuts the bottom plate 15, cuts the cut bottom plate 15 into two pieces, and welds the lap plate 17 on each side of each bottom plate 15. The lap plate 17 is in the shape of "L", the bottom plate 15 on each side of the partition plate 16 is placed between the two longitudinal fenders 111 through the lap plate 17, and the placement is movable, which means that the bottom plate 15 contacts with the longitudinal fender 111 but is not connected with the longitudinal fender 111. The heat insulation plate is arranged between the lap plate 17 and the longitudinal fender 111, and the heat insulation plate is made of fire-resistant cotton or thermal insulation cotton, so as to reduce the heat transferred from the bottom plate 15 to the vehicle body 11. Since the bottom plate 15 is not connected with the longitudinal fender 111, the thermal deformation of the bottom plate 15 will not involve the deformation of the vehicle body 11. The lap plate 17 is made of two metal material plates with different expansion coefficients and is pasted with each other, and after being heated, the lap plate 17 will be bent. In the case that no heat insulation plate is arranged, the lap plate 17 can be prevented from adhering to the longitudinal fender 111.

[0053] For example, the longitudinal beam 23 is provided with a bottom clamping groove, the lower edge of the support bar 24 is clamped into the bottom clamping groove, and the width of the bottom clamping groove is equal to the thickness of the support bar 24.

[0054] For example, the side clamping groove penetrates through the base 21, a plurality of side clamping grooves are arranged along the longitudinal direction of the base 21, the width of the side clamping groove is equal to the thickness of the support bar 24, and the height of the side clamping groove is equal to the height of the side edge of the support bar 24.

[0056] Exemplarily, the first nut 261 and the first screw rod 262 are fixedly connected as a whole, the length of the first connecting hole is greater than the outer diameter of the first nut 261, the first connecting hole is in a strip shape, and the end surface of the first screw rod 262 is chamfered, so that the first screw rod 262 is conveniently inserted.

[0057] The strip-shaped second connecting hole can facilitate the first bolt 26 to be quickly screwed into the first connecting hole, so that the briquetting is quickly disassembled.

[0058] Referring to Figure 16 Further, the cutting platform 20 comprises a plurality of machine legs 27, which are evenly distributed below the base body 21, each of the machine legs 27 comprises a leg body 271, a leg bottom 272 and a second bolt 273, the second bolt 273 comprises a second screw rod 2731, the second screw rod 2731 passes through a second screw hole in the leg body 271 and is in contact with the leg bottom 272, and the second screw rod 2731 is in threaded connection with the second screw hole.
