Therefore, it is necessary to design a pin device for fast assembling and disassembling static gas-liquid actuating elements.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a quick assembly disassembly static state gas-liquid actuator's round pin axle device, round pin axle device one end has the screw thread, is connected pneumatic cylinder and equipment through this round pin axle and earrings, uses two outer hexagonal lock nut to install on the round pin axle, makes the round pin axle can not the axial float, only needs loosen the nut during dismantlement, just can easily pull down the round pin axle, can realize quick replacement pneumatic cylinder. The nut locking type pin shaft replaces a traditional pin shaft, and is suitable for a gas-liquid execution element connecting pin shaft with large load, high temperature, high pressure, severe environment, large diameter, long disassembly time and large construction difficulty. Simple structure, reasonable design, low cost, safety and reliability.
The utility model adopts the technical proposal that: a pin shaft device for quickly dismounting and mounting a static gas-liquid actuating element comprises a connecting pin and two outer hexagonal locking nuts; the connecting pin consists of an outer hexagonal head, a shaft section and a threaded head, wherein an inner hexagonal is formed in the center of the outer hexagonal head, and four circular holes which are uniformly distributed on the circumference are formed in the outer circumference of the inner hexagonal; four round holes which are uniformly distributed on the circumference are formed in the outer hexagonal locking nut.
Further, the outer hexagon size on outer hexagon head and the outer hexagon lock nut is the same.
Furthermore, the hole positions of the four round holes on the outer hexagonal head and the outer hexagonal locking nut are the same.
The utility model has the advantages that: the pin shaft device is provided with threads at one end, a hydraulic cylinder is connected with equipment through the pin shaft and the lug ring, the double outer hexagonal locking nuts are arranged on the pin shaft, the pin shaft cannot axially shift, the pin shaft can be easily dismounted only by loosening the nuts during dismounting, and the hydraulic cylinder can be quickly replaced. And the outer hexagonal head and the outer hexagonal lock nut of the pin shaft are provided with round holes which can be used for pulling and screwing through the double cylindrical plates, so that the pin shaft is suitable for the environment with limited space.

Detailed Description
Example one
Referring to the figures, the pin shaft device for quickly dismounting and mounting the static gas-liquid actuating element comprises a connecting pin 1 and two outer hexagonal locking nuts 2; the connecting pin 1 consists of an outer hexagonal head 3, a shaft section 4 and a threaded head 5, wherein an inner hexagonal head 7 is arranged at the center of the outer hexagonal head 3, and four circular holes 6 uniformly distributed on the circumference are arranged on the outer circumference of the inner hexagonal head 7; four circular holes 6 which are uniformly distributed on the circumference are formed in the outer hexagonal locking nut 2; the outer hexagonal head 3 and the outer hexagonal locking nut 2 have the same outer hexagonal size; the hole positions of the four round holes 6 on the outer hexagonal head 3 and the outer hexagonal locking nut 2 are the same.
The diameter of the shaft section of the connecting pin is 60mm, the hydraulic cylinder is connected with the equipment earrings through the connecting pin, the outer hexagonal locking nut is installed on the threads of the connecting pin, the locking nut is installed outside the connecting pin, and the purpose of preventing the hydraulic cylinder from falling off due to axial movement of the pin shaft due to looseness of the nut and the threads of the pin shaft is achieved. The gas-liquid execution element connecting pin shaft with large load, high temperature, high pressure and severe environment and the diameter of more than 80mm is easy to disassemble and assemble, the preparation tools are simple, the number of constructors is small, and the replacement time of the nut locking type pin shaft is improved by more than 80 percent compared with the replacement time of the traditional pin shaft. The connecting pin adopts double nuts to fasten the installation of the pin shaft threads, so that the hydraulic cylinder can be completely ensured not to fall off due to the looseness of the pin shaft nuts under the extreme condition, and the equipment is damaged. When the disassembly space is large, the locking nut and the connecting pin are screwed by pulling the clamp on the outer hexagon of the connecting pin or the nut, when the operation space is small, the locking nut and the connecting pin are screwed by using a double-cylindrical plate pull (a wrench with two cylinders welded on an iron plate), and the cylinders of the double-cylindrical plate pull are inserted into the two round holes to realize clamping and screwing. The connecting pin can also be screwed using an L-shaped hexagonal wrench.
