The utility model relates to a crawler frame of a mining heading machine. The technical problem to be solved by the utility model is to provide the crawler frame of the mining heading machine. According to the technical scheme, the track frame comprises a track frame first cover plate, a track frame second cover plate, a first inner end plate, a second inner end plate, a main support first connecting plate, a main support second connecting plate and an interlocking block, the upper end of the first inner end plate and the upper end of the second inner end plate are each provided with an end plate reinforcing part, and reinforcing part limiting notches are formed in the end plate reinforcing parts; and first end plate fastening holes are formed in the middle of the first inner end plate and the middle of the second inner end plate at intervals. The crawler frame has the advantages that the crawler frame adopts a split structure, so that the size of the crawler frame component is reduced, the cost is effectively reduced, and the later transportation is facilitated; the interlocking block can enhance the overall strength of the first inner end plate and the second inner end plate, and the connection tightness of all components is effectively improved through horizontal, front-back and vertical three-way bolt connection.

This utility model discloses a slitting machine for processing printed velvet floor mats, including a support frame. A slitting mechanism is fixedly connected to the upper end of the support frame, and a cutting saw is fixedly connected to the bottom of the slitting mechanism. A fixed plate is fixedly connected to the lower end of the support frame. Multiple sets of first rotating shafts are movably connected to the outer side of the fixed plate, and the multiple sets of first rotating shafts are connected to each other via a second belt drive. Support legs are fixedly connected to the four corners of the bottom of the fixed plate. A pushing mechanism is installed on the upper end of the support legs, and a push plate is fixedly connected to one end of the pushing mechanism. A storage box is placed on the ground on one side of the push plate. The bottom of the cutting saw of this slitting machine for processing printed velvet floor mats is equipped with a bottom plate, which can more effectively cut the floor mats and prevent the conveyor belt from being cut, thus protecting the conveyor belt. At the same time, it can neatly collect the cut floor mats for easy transportation later.

The utility model relates to the technical field of box houses, and discloses an emergency rescue convenient box house convenient to assemble, which comprises a bottom plate, a plurality of reinforcing ribs are fixedly mounted at the bottom of the bottom plate, a plurality of grooves are formed in the top of the bottom plate, positioning columns are mounted in the grooves in an inserting manner, and inserting sleeves are arranged at the bottom of the bottom plate. A first side plate is installed in the inserting sleeve in an inserting mode, and a first bolt is arranged on the outer side of the inserting sleeve. According to the convenient emergency rescue box room convenient to assemble, through rapid disassembly and assembly of the inserting sleeves, the first side plates and the second side plates, through cooperation of first bolts and second bolts, overall rapid disassembly and assembly can be achieved, later-period transportation can be facilitated, the overall stability and bearing capacity can be enhanced through bottom reinforcing ribs, rapid disassembly and assembly of louver fans can be achieved through the mounting frames, and the assembly efficiency is improved. And through cooperation of the design of the first sealing sleeve and the second sealing sleeve, water and dust can be prevented from entering the box room from gaps, and therefore the temperature and cleanliness of the box room are kept.
