The flexible joint is characterized by comprising a motor, a joint connecting plate, a motor frame, a coupling, a bevel gear commutator, a first connecting plate, a connecting frame, a flexible output end, a second connecting plate, a support plate, a joint mounting plate and a support end, wherein the joint connecting plate and the joint mounting plate are fixedly connected through the support plate; the motor is fixedly connected with the motor frame through bolts; the motor frame is fixedly connected with the joint mounting plate through bolts; the motor is connected with the bevel gear commutator through the coupling; one end of the output shaft of the bevel gear commutator is connected with the flexible output end through a flexible output end sleeve and a second support bearing sequentially from inside to outside; the other end of the output shaft of the bevel gear commutator is connected with the support end through a support end sleeve and a first support bearing sequentially from inside to outside; the support end is connected with the first connecting plate.

The invention relates to a hand-held small pipeline operation device, comprising: a positioning module, a working module, and a cross universal hinge, the positioning module is connected with the working module through the cross universal hinge; the positioning module and the working module are respectively provided with a plurality of moving Legs, moving the legs makes the positioning module and working module move in the pipeline. The invention has the advantages of being able to realize walking, clamping and positioning in pipelines of different diameters, and automatically aligning the center of the device with the center of the pipeline, and can install different detection tools as required to perform different types of operations, with simple structure and high reliability. high.

The invention relates to the technical field of agricultural machinery, in particular to a forage pushing device based on frictional follow-up rotation, which comprises a housing, a frame and a push rod assembly; the cross-section of the housing is circular, and the inner side of the housing is The frame is connected, and the casing can rotate around the frame; there are at least two push rod assemblies, and each push rod assembly is vertically arranged on the traveling mechanism, and the push rod The push rod of the assembly is connected to the bottom of the frame; by controlling each push rod assembly, the inclination of the casing is realized so that the casing is in contact with the ground part or the lifting of the casing is realized. The invention adopts the friction force generated with the ground as the driving source, which saves cost and has a simple structure; the bottom end of the casing is not always in parallel contact and friction with the ground, and the running resistance of the traveling mechanism is small.

The invention provides a large full-gyration offshore platform crane which relates to the lifting machinery and comprises a rotary column, an arm support, a main lifting winch, an auxiliary lifting winch, an arm support variable-breadth winch, a gyration bearing drive mechanism, a main hanger hook, an auxiliary hanger hook and a driver cab. The arm support is connected with the middle part of therotary column through a hinge point mounted on the root of the arm support; the lower half part of the rotary column is arranged under a main deck and connected with a semi-diving platform through the gyration bearing drive mechanism. The gyration bearing mechanism is composed of an upper radial bearing, a lower radial bearing, a peg-tooth, a three-in-one decelerator, a centripetal thrust bearingand a rubber support; the upper radial bearing and the lower radial bearing are respectively mounted on the middle and the lower parts of the rotary column. The centripetal thrust bearing and the rubber bearing are sequentially mounted on the bottom part of the rotary column; the peg-tooth mounted on the lower deck is meshed with the three-in-one decelerator mounted on the corresponding position of the rotary column. The large full-gyration offshore platform crane has the advantages of novel, compact and practical structure, high efficiency and being a large full-gyration offshore platform crane with economical and practical properties.

The invention provides a clamp component and a tape laminator with the same. The clamp component is used for clamping a battery on a tape laminator and includes: a clamping structure for clamping a battery, wherein the battery clamped is fixed relative to the clamping structure; a rotary structure connected with the clamping structure and used for driving the clamping structure to rotate. During application of a tape to a battery, the rotary structure drives the clamping structure to rotate; rotation of the battery enables a tape to be wound to the battery. The clamp component according to thetechnical scheme is compact in structure and allows a tape laminator to have smaller overall size.

The invention provides a clamp for performing turning on a high pressure gas cylinder, and relates to the technical field of mechanical processing tools. The clamp comprises a rotating support and a telescopic chuck, wherein the rotating support comprises a base, a supporting bearing arranged in the base and a support body, the support body is connected with an inner ring of the supporting bearing, the outer ring of the supporting bearing is connected with the base, the telescopic chuck comprises a cylinder barrel, a telescopic rod and a claw, the claw is connected with the front end of the telescopic rod, the telescopic rod is arranged in the cylinder barrel, and rotating-prevention mechanisms matched with each other are arranged on the cylinder barrel and the telescopic rod. Large-scale reformation on a lathe is not needed when the clamp is used for performing turning on the high pressure gas cylinder, only the telescopic rod and the claw need to be pushed by a pushing device of the lathe, the weight of the telescopic rod and the claw is light, and the friction force between the telescopic rod and the cylinder barrel is small, so that the pushing device of the lathe can push the telescopic rod and the claw with a smaller push force, the clamp is small in abrasion during use, and the service life is long.
