Anchor rod drawing instrument for road construction measurement

Abstract

The utility model discloses an anchor rod drawing instrument for road construction measurement, and aims to solve the technical problem that in the prior art, when a manual pump is placed on the soft ground for use, the manual pump needs to be held by hands to avoid the situation that the manual pump inclines and turns over due to insufficient ground supporting force, so that the operation difficulty is increased. The anchor rod drawing instrument comprises a manual pump, a digital display pressure gauge, a high-pressure oil pipe and a hydraulic cylinder, the digital display pressure gauge is installed on the surface of the manual pump, the output end of the manual pump is connected to the input end of the hydraulic cylinder through the high-pressure oil pipe, and the two sides of two supporting legs of the manual pump are each provided with a supporting plate. A vertical shaft connected to the surface of a manual pump supporting foot penetrates through the surface of the supporting plate. According to the anchor rod drawing instrument, when the bidirectional lead screw rotates, the two threaded sleeves are driven to move in the direction away from each other, when the threaded sleeves move, the supporting plate is extruded to rotate through the first rotating shaft, the supporting rod and the second rotating shaft, the manual pump can be supported after the supporting plate rotates, and the stability and convenience of the manual pump in use are improved.
