The invention discloses a fixing and placing device for electromechanical equipment, and relates to the technical field of fixing and placing, the fixing and placing device for the electromechanical equipment further comprises a clamping device, a machining table is fixedly installed on the surface of a workbench, and machining equipment is fixedly installed on the surface of the workbench; a motor is fixedly installed at the bottom of the workbench, and the clamping device comprises a linkage plate, a first connecting rod, a linkage rod, a second connecting rod, a sliding box, an electric push rod, a triangular rod, a first clamping plate, a first fixing rod, a telescopic sliding rod, a second clamping plate, a second fixing rod and a pulley. And therefore, the materials are effectively prevented from deviating or shaking in the machining process, the working precision of the equipment is effectively improved, meanwhile, abrasion of the equipment in the using process is reduced, and the service life of the equipment is prolonged.

The application discloses a machine head for manufacturing soft polytetrafluoroethylene insulated wire and a processing method thereof. The machine head comprises a connecting head in the machine head, a die core is arranged at the top of the connecting head through a die core base, a die sleeve is arranged outside the die core, a center tube is arranged at the bottom center of the connecting head, the machine head comprises two conical bodies with different angles, a bottom conical angle and a top conical angle, the angle of the top conical angle is smaller than that of the bottom conical angle, the wire bearing section of the machine head is horizontal to the die core base, the connecting head comprises two trapezoidal cones with different angles, a bottom conical angle and a top conical angle, the bottom conical angle is the same as the bottom conical angle, and the top conical angle is smaller than the top conical angle, a conductor anti-shaking device is arranged at the bottom of the center tube, the conductor anti-shaking device comprises arc-shaped groove wheels and springs, and the arc-shaped groove wheels are connected through a center rod. The steps are as follows: filling; center tube and die core related component installation; machine head and die sleeve installation; and pushing and extruding. The application can make the insulation layer outside the conductor more compact, and avoid the bending phenomenon of the conductor during processing.

The invention relates to the technical field of building construction, and discloses an earthwork tamping device and a tamping method.The earthwork tamping device comprises an engineering vehicle, a swing arm arranged on one side of the engineering vehicle, a breaking hammer arranged at the lower end of the swing arm, a hammer rod arranged at the lower end of the breaking hammer and a hammering assembly arranged at the lower end of the hammer rod; wherein the breaking hammer is used for driving the hammering assembly to move up and down; and the hammering assembly is used for compacting earthwork. The hammering assembly is driven by the breaking hammer to move up and down, the earthwork is repeatedly rolled through the impact force of the breaking hammer, and therefore the effect of rapidly and efficiently compacting the subbase earthwork with high quality is achieved.

The utility model relates to the field of municipal engineering, in particular to a municipal road maintenance device. The utility model provides a municipal road maintenance device which can be used for quickly paving a road and quickly compacting the paved road surface, so that an asphalt road surface is effectively repaired, and the service life of the road is prolonged. A municipal road maintenance device comprises a support, a hand pushing frame, a wheel shaft, walking wheels and the like. A hand pushing frame is fixedly connected to the support, wheel shafts are rotationally connected to the two sides of the lower portion of the support, and walking wheels are fixedly connected to the two ends of the two wheel shafts. Asphalt concrete flows to the ground from the inside of the asphalt tank to lay the ground, and then a worker pushes the bracket forwards, so that the compaction block compacts the asphalt concrete laid on the ground, the pavement compaction degree is effectively improved, and the asphalt pavement is quickly repaired.
