Embodiment

[0030] Such as figure 1 As shown, the auxiliary device for laying sand for buried cables in this embodiment includes a driving mechanism 1 , a pull rope 2 and a clamp 3 for clamping or loosening buried cables 4 .

[0031] The clamp 3 includes two half-clamps 31 with opposite openings. The two half-clamps 31 are hinged by the first hinge shaft 32 arranged along the axial direction of the buried cable 4. The lower end of the stay rope 2 is connected to the two half-clamps 31. are connected, the upper end of the drawstring 2 is connected with the drive mechanism 1, and the drive mechanism 1 can drive the drawstring 2 to pull to drive the two half-clamps 31 to rotate around the first hinge shaft 32 to close together to clamp the buried cable 4, drive The mechanism 1 can drive the pull rope 2 down to drive the two half-clamps 31 to rotate around the first hinge shaft 32 to open to release the buried cable 4 .

[0032] see figure 2 The half clamp 31 includes a clamp arm 311 for c...

Abstract

The invention discloses a buried cable sand laying auxiliary device and a method for assisting sand laying by using the buried cable sand laying auxiliary device. The buried cable sand laying auxiliary device comprises a driving mechanism, a pull rope and a clamp for clamping or loosening a buried cable, and the clamp comprises two semi-holding clamps with opposite openings; the two semi-holding clamps are hinged through a first hinge shaft arranged in the axial direction of the buried cable, the lower end of the pull rope is connected with the two semi-holding clamps, the upper end of the pull rope is connected with the driving mechanism, and the driving mechanism can drive the pull rope to be lifted to drive the two semi-holding clamps to rotate around the first hinge shaft to be folded so as to clamp the buried cable; and the driving mechanism can drive the pull rope to be put down so as to drive the two semi-holding clamps to rotate around the first hinge shaft to be opened, and therefore the buried cable is loosened. The buried cable sand laying auxiliary device is used for assisting in sand laying, two original sand laying procedures can be reduced to one sand laying procedure, the number of acceptance times is decreased, and therefore the purposes of reducing cost, increasing benefits and accelerating a construction progress are achieved.

Description

technical field [0001] The invention relates to the technical field of wind power construction, in particular to an auxiliary sand-spraying device for buried cables and a method for assisting sand-spreading by using the auxiliary sand-spraying device for buried cables. Background technique [0002] The wind turbines of wind power projects in mountainous areas are mainly arranged along the ridge or halfway up the continuous mountain range, and the wind turbines are connected by cables. The power generated by each fan is sent to the step-up station through the cable after being transformed by the box transformer; after being transformed by the main transformer equipment of the step-up station, it is connected to the State Grid through the sending line; and then connected to thousands of households through the State Grid for production life use. Restricted by factors such as topography and geology, climate conditions, land acquisition for construction and forest land protectio...
