The invention discloses a pipe arranging device and pipe rod pipe arranging conveying equipment for oil field well workover, and relates to the technical field of oil field well workover equipment.The pipe rod pipe arranging conveying equipment comprises the pipe arranging device and a conveyor, the pipe arranging device comprises at least two sets of power cross arm assemblies arranged side by side, and each power cross arm assembly comprises a cross arm support and two push rods arranged in parallel; the cross arm support is of a T-shaped structure, and push rods are installed on the two sides of a vertical rib. A plurality of push plates are arranged on the push rod at equal intervals, and one end of each push plate is connected with a driving cylinder fixed on the cross arm support; the conveyor comprises a machine frame, a side beam and an extending beam, and the side beam is vertically installed on the machine frame in a sliding mode and connected with a lifting mechanism. The extension beam is horizontally and slidably mounted on the side beam, and a roller way is mounted on the side surface; when the roller way ascends to the output end of the pipe arranging device, the roller way lifts the oil pipe to enter the next working procedure; the pipe arranging device and the conveyor in the equipment are used in cooperation, the mechanical structures of the pipe arranging device and the conveyor are simple, and well repair automation operation is easy to widely popularize and apply.

According to the method for preparing the diborane provided by the invention, boron trichloride does not need to be fed for multiple times in stages, complicated reaction temperature control is not needed, intermediate control steps in the production process are few, the generation efficiency of the diborane is favorably improved, and the process difficulty is reduced. The method comprises the following steps: reacting boron trichloride with metal hydroboron in the presence of trimethyl borate and an ether solvent to prepare diborane gas; the boron trichloride is fed in a one-step feeding manner.

The utility model relates to a pressing and unfolding device of a satellite antenna, which does not need an independent locking and releasing mechanism. Comprising the steps that a flexible antenna is arranged on the side face, facing a solar panel, of a satellite body; when the solar panel is in a locked state, the flexible antenna is bent and arranged between the satellite body and the solar panel and is in a compressed state; when the solar panel is unfolded, the flexible antenna is unfolded along with the solar panel, the compressed state is converted into the natural state, the flexible antenna is smoothly unfolded, an additional locking and releasing mechanism is not needed in the whole process, the manufacturing and maintenance cost is reduced, and the risk of task failure caused by complex mechanism faults is reduced.

The invention relates to a bistable adhesion foot, which belongs to the technical field of robot actuating mechanisms, and comprises a shell and a sliding sleeve which slides back and forth together with a sleeve formed on the target surface side of the shell, and a plurality of curved bars which penetrate through the sleeve and can swing relative to the sleeve in the sliding direction of the sliding sleeve are hinged to the circumferential array of the sliding sleeve. The tail end of the curved bar is fixedly connected with a viscous material; a plurality of slope buckles are arranged on the inner wall of the shell, jumping sliding blocks are arranged at the positions, corresponding to the slope buckles, of the outer wall of the sliding sleeve, and the shell can elastically deform in the radial direction at the positions of the slope buckles so that the jumping sliding blocks can be attached to the slope buckles all the time when moving upwards or downwards along with the sliding sleeve to drive the curved bar to swing in a reciprocating mode. The shell is matched with the jumping sliding block of the sliding sleeve through the slope buckle, so that the adhesion foot has two stable states including an adhesion state and a desorption state, application of a passive adhesion material to the adhesion foot is facilitated, the control complexity of related equipment is effectively reduced, and the application reliability of the related equipment is improved.

The application relates to the technical field of clamps, in particular to a fixing device and method for EGR cooler support machining, which comprises a base and an EGR cooler support, further comprises a supporting rod, the side surface of the supporting rod is provided with a lower expansion clamp used for abutting against the lower part of the side surface of the EGR cooler support and an upper expansion clamp used for abutting against the upper part of the side surface of the EGR cooler support, a gas supply mechanism is used for supplying gas to the lower expansion clamp and the upper expansion clamp, so that the lower expansion clamp and the upper expansion clamp are expanded to clamp the EGR cooler support; a sliding base is slidably arranged on the base and used for bearing the supporting rod; a locking mechanism is used for locking the position of the sliding base after the lower expansion clamp and the upper expansion clamp abut against the side surface of the EGR cooler support, the locking mechanism comprises a movable abutting rod arranged in the base and an arc plate arranged in the sliding base and abutting against the abutting rod, a driving assembly is arranged in the sliding base and is driven by the arc plate to provide power for the gas supply mechanism; a rigid adjusting mechanism comprises a double-end plug rod arranged in the supporting rod and an electric push rod used for driving the double-end plug rod to move.
