The invention discloses a self-anchored thermal insulation decorative assembly type wallboard and a counter-attack preparation process thereof. The thermal insulation decorative assembly type wallboard sequentially comprises a concrete structure layer, a thermal insulation layer and a veneer layer from inside to outside, wherein the veneer layer is formed by hard thin plates, and an inner anchoring part is embedded in the back of each hard thin plate; an outer anchoring part is inserted in each inner anchoring part. The preparation process of the assembly type wallboard comprises the followingsteps: prefabricating each thermal insulation decorative integrated board with the embedded inner anchoring part veneer layer in the back, and fixing a formwork; reversely spreading the thermal insulation decorative integrated boards on a steel formwork platform one by one; installing one outer anchoring part on each inner anchoring part of each thermal insulation decorative integrated board; filling with slab joints; placing prefabricated steel bar grids or cages; pouring concrete and vibrating; maintaining; removing the formwork. The obtained self-anchored thermal insulation decorative assembly type wallboard and the counter-attack preparation process have the advantages of simple manufacturing steps, short construction period, fire safety, energy-saving and thermal insulation, and lowcost of natural granite sheet veneer.

The invention discloses carton printing equipment and method, and relates to the technical field of carton printing, the carton printing equipment comprises a concave workbench, a conveying belt is arranged in the concave workbench, and a printing piece is arranged on the upper portion of the rear side of the concave workbench; a conveying anti-deviation assembly is arranged at the position, located in front of a printing piece, of the upper portion of the concave workbench and comprises a concave base, two guide grooves are symmetrically formed in the upper portion of the concave base, and guide shafts are horizontally connected into the two guide grooves. According to the carton printing equipment and method, in the printing and conveying process of a carton board, under the work of a servo motor, the two guide wheels can clamp the two sides of the carton board, then under the work of a motor, the two guide wheels clamp and convey a carton, it is guaranteed that the carton board is located in the middle of the conveying belt all the time, and the carton board is not prone to falling off. And dislocation and deviation of the carton board are prevented.

There is disclosed an apparatus for mooring a structure, the apparatus includes a first portion for receiving a portion of a line, such as a mooring line, extending from a structure. A guide portion for guiding a/the portion of a line received by the first portion, the guide portion being movably connected to the first portion and a second portion for connecting or coupling the apparatus to a seabed or a further structure located thereon, the second portion being movably connected to the first portion and/or guide portion.

The invention discloses an automatic vacuum-pumping food preservation device and a using method thereof, and relates to the technical field of food preservation. The device comprises a bottom plate, wherein two sets of symmetrical columns are fixedly connected to the upper surface of the bottom plate, the top ends of the columns are fixedly connected with a top plate, the upper surface of the bottom plate is fixedly provided with a control panel, the front surface of the control panel is provided with a switch button, and the bottom surface of the top plate is fixedly provided with an electricpush rod. According to the automatic vacuum-pumping food preservation device and the using method thereof, through the joint action of the switch button, the control panel, the columns, the movable plate, a first travel switch, a second travel switch, the electric push rod, a vacuum pump, a negative pressure sensor, a support plate, a telescopic rod, a second spring, a piston, a step column, a one-way valve and an air extraction hole, the device has the advantages that the vacuum in a box body can be monitored in real time, the vacuum state in the box body is ensured, and the problem that thegeneral vacuum preservation device cannot subsequently monitor the vacuum inside the box body containing food is solved.

The invention discloses a power construction hanging ladder fixing structure and a power construction hanging ladder. The power construction hanging ladder fixing structure comprises a first stand column, transverse rods are fixedly connected to the inner side of the first stand column, and a second stand column is fixedly connected to the end, away from the first stand column, of the transverse rods. The power construction hanging ladder fixing structure and the power construction hanging ladder are jointly constructed by arranging the first stand column, the transverse rods, the second standcolumn, a hook, a storage battery box, a machine box, a servo motor, a threaded cylinder, a threaded rod and a threaded hole, and the power construction hanging ladder is formed by arranging the first stand column, the transverse rods, the second stand column and the hook. When the hook is hung on a cable, the servo motor is started through an external controller, the servo motor drives the threaded rod to rotate at the moment, the threaded rod enables the threaded rod and the servo motor to move left and right under limiting and supporting of the threaded cylinder, and when the threaded rodmoves to the position of the threaded hole, the servo motor drives the threaded rod to rotate.

The invention discloses a spring string feeding device and a spring string conveying mode thereof. The spring string feeding device comprises a first conveying mechanism, a second conveying mechanism and a welding and cutting mechanism, wherein the first conveying mechanism and the second conveying mechanism are clamping and conveying devices which are arranged up and down; and when the output end of one first conveying mechanism directly faces the input end of the second conveying mechanism, the output end of the first conveying mechanism penetrates through the welding and cutting mechanism so as to be tightly attached to the input end of the second conveying mechanism. According to the spring string feeding device and the spring string conveying mode thereof provided by the invention, through arranging the first conveying mechanism and the second conveying mechanism which are clamped up and down, when spring strings are fed, the output end of the first conveying mechanism is tightly attached to the input end of the second conveying mechanism, so that the spring strings are prevented from being clamped at the input end of the second conveying mechanism; and secondly, in the resetting process, the conveying speed of the first conveying mechanism is equal to the translation speed of the first conveying mechanism, so that springs cannot be pulled due to the speed difference caused by resetting in the resetting process, and position dislocation of the spring strings is avoided.
