The lower end part of the bearing shaft is in threaded connection with a prestress adjusting nut, the spring limiting plate is movably arranged on the prestress adjusting nut, and the prestress adjusting is realized by adjusting the telescopic amount of the spring limiting plate through the prestress adjusting nut.
Lubricating grease is injected between the sleeve and the bearing shaft and between the sleeve and the bearing cylindrical compression spring, so that the friction between the bearing shaft and the matching block is reduced, and the relation of the compression ratio between a heavy object and the bearing cylindrical compression spring is avoided being influenced.
The upper end of the sleeve is welded with the welding flange, and the sealing rubber pad is arranged between the welding flange and the sealing cover, so that a sealing space is formed in the cavity of the sleeve, excessive air does not enter the cavity, the lubricating grease is protected from being oxidized too early before being used, and the excessive lubricating grease is prevented from being oxidized when not being used.
The lower end of the bearing shaft is in a thread design and is used for connecting a bearing platform or other bearing parts.
The tail end of the bearing shaft is provided with a pin hole, and an opening pin is additionally arranged in the pin hole to prevent the slotted nut from loosening to cause potential safety hazards.
The sleeve is fixedly connected with the matching block, such as welded.
The utility model discloses utilize hooke's law to realize simulating the fuselage action of sinking. The wire diameter and the bearing capacity of the bearing spring are larger than those of the reset spring, so that the carrying plane returns to the original position when no load bearing heavy object exists.
The simulation process is that when a heavy object is loaded at the lower end of the bearing shaft, the bearing shaft is pulled out from the sleeve because the gravity acts on the bearing cylindrical compression spring through the bearing shaft, the spring is compressed; and loading a heavy object to the lower end of the bearing shaft again, and continuously pulling the bearing shaft out of the sleeve in the same way until the bearing cylindrical compression spring is completely compressed or the bearing shaft limiting shaft shoulder is reached.
When the heavy object at the lower end of the bearing shaft is unloaded step by step, the bearing shaft can rise to a certain height under the combined action of the reset cylindrical compression spring and the bearing cylindrical compression spring when a part of load is unloaded. The bearing shaft is unloaded again, and then the bearing shaft ascends again until the original position is recovered.
The reaction force of the return cylindrical compression spring and the stress of the bearing cylindrical compression spring during assembly are certain. In addition, when loading and unloading the load, the hoisting equipment is stably separated from the load unhooking. Therefore, the bearing shaft does not shake up and down when loading and unloading the load, and the real state of the aircraft when loading and unloading the load is met as much as possible.
The utility model has the advantages that: through increasing hoisting equipment altitude mixture control simulation training and fuselage when sinking suddenly, feel the fear that hoisting equipment operator arouses, simple structure, the processing and the maintenance of being convenient for, low cost, simple to operate, it is little to occupy the space, conveniently carries out the module combination.
The present invention will be further explained with reference to the drawings and examples.
