The utility model relates to the technical field of steel bar machining, in particular to a convenient steel bar machining auxiliary structure which comprises a base, a supporting seat is arranged on the left side of the top end wall of the base, a driving shaft is rotationally connected to the right side wall of the supporting seat through a first bearing, and a conveying wheel is connected to the right side of the outer wall of the driving shaft in an interference fit mode. A connecting base is arranged on the right side of the top end wall of the base, and a steel bar lifting and pressing mechanism is arranged on the top end wall of the connecting base. The adjustable pressing wheel structure is arranged above the steel bar, the motor is used for driving the lead screw to drive the pressing wheel to move up and down, the steel bar is stably pressed on the conveying wheel, and compared with the prior art that the steel bar makes contact with an idler wheel only through the dead weight of the steel bar, the design obviously increases positive pressure between the steel bar and the conveying wheel, and then friction force is improved. The slipping phenomenon caused by factors such as small diameter, light weight, smooth surface or conveying speed change of the steel bar is effectively avoided, and the stable and reliable conveying process of the steel bar is ensured.

The invention belongs to the field of cabling machines, and particularly relates to a full-automatic cable cabling machine with an active deviation rectifying function, which comprises a central pay-off support, two pay-off rollers I are mounted in the middle of the central pay-off support, a wire outlet frame is fixedly connected to the end part of the central pay-off support, a central arm is fixedly connected to the end part of the wire outlet frame, and two pay-off rollers II are mounted in the central pay-off support. A driving box used for driving the wire outlet frame to rotate is installed on the outer side of the end of the wire outlet frame, a first transmission disc and a second transmission disc are fixedly connected to the outer side of the center arm, and a plurality of side disc pay-off supports are installed between the first transmission disc and the second transmission disc. Friction force needing to be overcome by rotation of the first pay-off reel and the second pay-off reel can be changed in real time, in the cabling process, the straightening and deformation states of raw material wires are always kept, the quality of the head and the tail of a formed cable are kept the same, and meanwhile the problems of bloating, dislocation, deformation and the like after the cable is formed are effectively solved.

The utility model discloses a kind of electric connectors, it is related to connector technical field, wherein, electric connector includes: male end, including first shell;Female end, including second shell;And first electric connection component, including spring and tubular conductor, one of spring and tubular conductor is located in the inside of first shell, the other is located in the inside of second shell;Wherein, first shell is inserted into second shell, so that spring and tubular conductor abutment realizes electric connection, and spring produces radial force applied to tubular conductor along tubular conductor.The technical scheme provided by the utility model provides a kind of electric connector, and male end and female end are closely connected, not easy to loosen.

The invention relates to the technical field of electric power overhaul auxiliary equipment, and particularly discloses a remotely-controllable electric power overhaul lighting device which comprises a pole climbing device composed of at least two pole climbing robots and a connecting piece, a lighting device detachably installed on the connecting piece and a remote control terminal. The pole-climbing robot is provided with a driving wheel, a control module and a locking mechanism, and the lighting device comprises a lighting lamp with a battery and is provided with a pluggable power supply connecting wire which can be selectively connected with the battery with the battery, a battery of the pole-climbing robot or an external power supply. Remote control lifting and flexible deployment of the lighting device are achieved, the power supply mode is independent and switchable, and the safety, adaptability and cruising ability of high-altitude overhaul operation are remarkably improved.

This invention relates to the field of power transmission line operations and provides a power grid sealing and traction device. The power grid sealing and traction device includes: a frame assembly with an opening for inserting a conductor; a traction assembly including a plurality of first rollers and a first drive device; the first rollers and the first drive device are disposed within the frame assembly, located at the top of the opening, the first rollers supporting the conductor and rolling relative to it, and the first drive device driving the first rollers to rotate; and a top-line assembly including a top rod, a second roller, and a second drive device; the second drive device driving the second roller to press against the conductor. The traction assembly rolls and pulls above the conductor, while the top-line assembly presses against the conductor from below. This dual-action structure of upper traction and lower pressing improves the smoothness of the traction action.

The application aims to provide a connection structure of a blood flow channel and a sleeve with high bonding reliability, which comprises a blood flow channel and a sleeve. The blood flow channel comprises a round tube, and a connecting tube section is extended from the end of the round tube near one side of the sleeve. The outer wall of the connecting tube section is in a shape of a tapered column with a large middle diameter and small diameters on both sides. The maximum outer diameter of the connecting tube section is smaller than the outer diameter of the round tube, and the sleeve is sleeved on the outer periphery of the connecting tube section and is bonded by glue. The outer wall of the connecting tube section is in a shape of a tapered column with a large middle diameter and small diameters on both sides, which increases the contact area of the sleeve and the connecting tube section and increases the pulling force between them. When the sleeve is stretched and deformed, the contact surface is subjected to normal pressure and glue shear force, and the normal pressure increases with the increase of the deformation amount of the sleeve at this position, which provides a guarantee for the reliable connection between the sleeve and the blood flow channel.

The utility model provides a floating type driving wheel assembly which comprises a driving seat, a driving device installed on the driving seat and a bottom plate connected with a frame. A floating mechanism is mounted between the bottom plate and the driving seat; when the driving device floats up and down, the bottom plate synchronously follows up through the floating mechanism and is subjected to acting force in the up-down direction, the utility model further provides an AGV forklift which comprises a frame and a driving assembly, and the floating type driving wheel assembly is installed in the driving assembly. The problems that a force increasing mechanism is additionally arranged to balance the road holding force of a single steering wheel, pressure of back space layout is caused, and meanwhile energy consumption is large are solved.
