The utility model discloses a vibration reduction corrugated pipe assembly and a refrigerating machine, which comprise a corrugated pipe main body, a corrugated pipe upper connecting flange, a corrugated pipe lower connecting flange and a telescopic support assembly, the two ends of the corrugated pipe main body are respectively connected with the corrugated pipe upper connecting flange and the corrugated pipe lower connecting flange; the corrugated pipe upper connecting flange is connected with the mounting flange of the cold head, the corrugated pipe lower connecting flange is connected with the normal-temperature cold disc, and the telescopic supporting assembly is directly or indirectly connected with the cold head and the normal-temperature cold disc. Through the corrugated pipe upper connecting flange and the corrugated pipe lower connecting flange, compared with an existing vibration reduction assembly, a secondary support can be omitted, the structure is more compact, the weight of the whole machine can be reduced under the same condition, and the occupied area can be reduced. In addition, the cold head can be supported through the telescopic supporting assembly, the corrugated pipe body can be conveniently adjusted to be in a natural extension state, and therefore the service life of the corrugated pipe body can be prolonged.

The utility model discloses an offshore platform pile foundation static load test counter-force device which comprises a main beam, an auxiliary beam, a fixing frame, a first jack, a second jack, a displacement sensor, a pressure sensor and a control unit. The auxiliary beams comprise the first auxiliary beam and the second auxiliary beam. The top of the main beam is fixedly connected with the center of the bottom of the first auxiliary beam and the center of the bottom of the second auxiliary beam. The first jack is arranged in the vertical direction and fixed to the top of the main pile, and the output end of the first jack makes contact with the center of the bottom of the main beam. The two sets of second jacks are arranged in the horizontal direction and fixed to the bottoms of the two ends of the main beam correspondingly, and the output ends of the two sets of second jacks make contact with the outer sides of the first auxiliary pile and the second auxiliary pile correspondingly. The displacement sensors are arranged on the main pile and the auxiliary pile correspondingly, and the pressure sensors are arranged at the output ends of the first jack and the second jack correspondingly. The counter-force device disclosed by the utility model can be used for carrying out horizontal static thrust and vertical compression resistance static load tests on an offshore pile foundation platform, and is low in cost and simple and convenient to operate.

The application relates to the technical field of lighting appliances, in particular to a lamp mounting shell module and a lamp. The lamp mounting shell module comprises a mounting support, a mounting shell and a fastener. The mounting support comprises a support body and a positioning piece. The positioning piece is fixedly arranged on the support body. The support body is arranged on a mounting site of the lamp. The support body is provided with a connecting hole. The mounting shell comprises a side wall. The side wall is arranged in a surrounding mode to form a containing space. The side wall is provided with a locking groove group. The locking groove group comprises a first positioning groove and a second positioning groove. The first positioning groove and the second positioning groove respectively extend along the circumference of the side wall. The mounting support is arranged in the containing space to make the connecting hole and the second positioning groove communicate. The positioning piece is movably embedded in the first positioning groove. The fastener is arranged in the second positioning groove and the connecting hole and is used for connecting the side wall and the support body. The lamp comprises a light-emitting assembly and the lamp mounting shell module. The connection reliability between the mounting shell and the mounting support of the lamp mounting shell module is high.
