The application discloses a horizontal moving electromagnetic friction equivalent simulation test device, and belongs to the technical field of space and deep space exploration. The upper part of an electromagnetic sleeve is a sleeve piece with large flexibility. An electromagnet is arranged on the sleeve piece. The electromagnetic attraction force is changed by changing the current of the electromagnet, so that the deformation of the sleeve piece is affected to change the normal pressure of the sleeve piece on a vertical rod. The friction between the sleeve piece of the electromagnetic sleeve and the vertical rod is changed, and part of the gravity is offset to control the equivalent gravity. The lower part of the electromagnetic sleeve is a supporting piece. The edge of the supporting piece is a bolt hole. The bolt hole is connected with a test prototype. The current of the electromagnet at the upper end of the electromagnetic sleeve is controlled and adjusted in real time, so that the control and adjustment of the equivalent gravity are realized. The moving speed of a horizontal moving platform is controlled, so that the vertical drop shock and the horizontal speed coupling working condition are simulated. The accuracy and applicability of the equivalent gravity acceleration simulation test are improved.

The application discloses a kind of airflow weight-reducing electric iron, including outer shell, control unit, high-speed air supply device and ironing unit, ironing unit is located at the lower end of outer shell, ironing unit has ironing surface, outer shell is equipped with the air inlet structure that is communicated with the air inlet end of high-speed air supply device, the lower end surface of outer shell is equipped with the air outlet structure that is communicated with the air outlet end of high-speed air supply device, so that the high-speed airflow generated by high-speed air supply device flows through air outlet structure and is sprayed towards the side of the ironed object, high-speed airflow can generate upward thrust on electric iron, so as to offset part of the gravity of electric iron or make electric iron form suspended state, ironing surface is protruded downwards from air outlet structure, high-speed airflow is generated by high-speed air supply device and sprayed towards the side of the ironed object, airflow thrust can offset part of the gravity of electric iron or make it suspended, greatly reduce the feeling of weight when hand-held operation, avoid arm fatigue caused by long-time ironing, improve use comfort and ironing efficiency.

The utility model relates to mechanical technical field, concretely is a kind of for the sliding board with air hole of sliding platform. Including the sliding board of inclination arrangement, the lower end of the one side of sliding board is connected with connecting plate, connecting plate both sides are equipped with side plate, and the inside of sliding board lower end, connecting plate, side plate forms cavity, and air pipe one end connects compressed air source, and air pipe other end is connected with the connector assembly on connecting plate, and sliding board surface is equipped with several air holes. Compared with prior art, upward airflow overcomes the partial gravity of bagged cement, and the dust on the surface of sliding board is cleaned to a certain extent, the friction between bagged cement and sliding board is reduced, and the smooth operation of equipment is more beneficial.

The present application relates to the technical field of goods transfer, in particular to an energy recovery type rail type warehouse goods loading and unloading transfer device. It comprises an I-shaped rail laid on the top of a base, an I-shaped rail top rollingly adheres to a rail car, the top of the rail car is fixedly connected with a mounting base; the top of the mounting base is provided with a load bearing plate with adjustable spacing from itself, and the two sides of the rail car are fixedly connected with a generator moving synchronously with itself; the load bearing plate receives heavy objects at a high position to store gravitational potential energy, the heavy objects drive the load bearing plate to slide down along the surfaces of the first connecting rod and the second connecting rod, the spring is synchronously compressed to convert part of the gravitational potential energy into elastic potential energy, buffer and stabilize the descending speed of the load bearing plate, and avoid the sudden increase of the rotating speed of the generator driving wheel; the load bearing plate drives the driving rack to slide downward when descending, the driving rack meshes with the driving gear to rotate, and then drives the generator driving wheel to rotate to generate electricity, and converts the gravitational potential energy into electrical energy and stores it.
