The invention belongs to the technical field of embossment, and particularly relates to a movable embossment structure which comprises a rack, an installation cavity is formed in the outer side of the rack, a plurality of display assemblies are installed in the installation cavity in a matrix state, and the multiple display assemblies form an embossment shape through stretching and retracting of the display assemblies. According to the movable embossment structure, a certain part in a whole image is displayed through the display screens on the display assemblies, the whole image is jointly displayed through the multiple display assemblies, when the image needs to be replaced with other patterns, only the image stored in the intelligent control module needs to be replaced, the embossment can be replaced with different patterns, the embossment patterns are easily replaced, and the replacement efficiency is improved. According to the three-dimensional embossment structure, the multiple display assemblies are arranged to adapt to the requirement changes of different occasions, the flexibility and diversity are improved, meanwhile, the replacement cost and resource consumption are reduced, sustainable development and wide application of the embossment art are promoted, the multiple display assemblies can stretch out and draw back to different degrees, and the formed embossment shape is more three-dimensional and good in decoration effect.

This application belongs to the field of work machinery technology and provides a hydropneumatic suspension hydraulic control valve, a hydropneumatic suspension hydraulic system, and work machinery. The hydropneumatic suspension hydraulic control valve has a first oil port, a second oil port, a third oil port, and a fourth oil port. The valve also includes a first oil passage and a second oil passage. The first oil passage connects the first oil port and the fourth oil port, and the second oil passage connects the second oil port and the third oil port. A first shut-off valve for controlling on / off is installed on the first oil passage, and a second shut-off valve for controlling on / off is installed on the second oil passage. The first and second shut-off valves are hydraulically controlled directional valves, and a connecting channel is provided between their hydraulically controlled directional ports. A pilot control valve for controlling on / off is installed between the connecting channel and the pilot oil source inlet. This valve has a simple control logic and produces minimal vehicle body posture oscillation when performing rigid-flexible support switching control.

The utility model relates to the technical field of stirrer, concretely to a stirring head quick replacement structure, including electric mixer body, electric mixer body left end is connected with the stirring head, the electric mixer body outer surface left end is installed with auxiliary mechanism, the auxiliary mechanism includes auxiliary cover, the auxiliary ring of welding in auxiliary cover left end and the limiting frame of welding in auxiliary ring right side surface, the limiting frame inside is provided with the limiting block, when needing to replace the stirring head, through the right movement of the auxiliary cover of pushing, make the auxiliary ring drive the right movement of sliding connecting block, make the limiting insertion rod can leave the limiting mechanism, then through the limiting groove cooperation limiting block will fix the position of auxiliary cover, can fix the position of sliding connecting block, can conveniently control limiting mechanism to replace the stirring head subsequently, through auxiliary mechanism makes the user can conveniently synchronous control both sides' locking mechanism, can more quickly replace the stirring head.

The application relates to the field of mine equipment, and discloses a mine underground temperature reduction and waste heat recycling device and a method thereof, which effectively solve the problem that when the temperature of a waste heat boiler rises to a certain value, the heat transfer effect becomes poor, and the device comprises a mine frame, a mounting plate is arranged in the mine frame, a waste heat recycling assembly is arranged at the top of the mounting plate, the waste heat recycling assembly comprises two bases which are symmetrically arranged at the top of the mounting plate, a waste heat boiler is arranged at the top of the base, a furnace cavity is arranged in the waste heat boiler, a heat exchange spiral groove is arranged in the waste heat boiler, and the heat exchange spiral groove is arranged at the outside of the furnace cavity. The application is provided with two waste heat boilers for air heat absorption work, when the heat absorption medium in the furnace cavity of one waste heat boiler reaches a high temperature, the other waste heat boiler can be started to work, the two waste heat boilers can alternately transfer heat, and the underground temperature reduction effect and the waste heat recycling efficiency are ensured.

The utility model discloses a cutting device for civil air defense door manufacturing, which comprises a working table, a mounting groove is formed in the working table, two sliding blocks are connected in the mounting groove in a sliding manner, clamping plates for clamping and fixing a civil air defense door are fixedly connected to the two sliding blocks, an arch frame is connected to the working table, and the arch frame is fixedly connected to the working table. A cutting machine used for cutting the civil defense door is connected to the arched frame, and a supporting plate is arranged below the cutting machine. According to the cutting device for civil air defense door manufacturing, the civil air defense door is supported by arranging the supporting plate, the supporting plate and the cutting machine are connected to the arch frame in the same vertical direction, the arch frame and the cutting machine are driven by the moving mechanism to move to the proper position, and meanwhile a cutting groove in the supporting plate is opposite to a cutting blade of the cutting machine; the civil air defense door is supported by the supporting plate, cutting of the civil air defense door by the cutting machine is not affected, and the situation that the civil air defense door deforms due to lack of supporting in the cutting process, and the cutting quality of the civil air defense door is affected is avoided.
