Problems solved by technology
[0004] However, due to the sudden drop of the hammer rod 3 and the heavy hammer 32, the momentary force of the hoisting cable 12 changes greatly, thereby causing the hoisting arm 11 to rise upwards; and high-frequency vibration; The crack expands, thereby accelerating the damage of the lifting arm 11 and affecting the service life of the lifting arm 11

The invention discloses a hammering system for high-strain detection of a foundation pile, relates to the technical field of foundation pile detection, and aims to solve the technical problem that thedamage of a lifting arm is accelerated due to sudden falling of a hammer rod and a heavy hammer. According to key points of the technical scheme, before the hammer rod needs to be released, firstly,an operator pulls a pull rope, and thus a spring clamp is opened and separated from a fixing hole; at the moment, the lifting arm loses connection with the hammer rod; and then a release rope is pulled, a fixing rod is separated from a supporting hole, and due to the action of gravity, the heavy hammer falls downwards to realize impact on the foundation pile. During falling of the heavy hammer, the lifting arm is separated from the hammer rod, thus high-frequency vibration of the lifting arm is effectively avoided, and damage of the lifting arm is effectively delayed.
Description
technical field [0001] The invention relates to the technical field of foundation pile detection, in particular to a hammering system for high strain detection of foundation piles. Background technique [0002] After the foundation pile is inserted into the ground, the high-strain performance of the foundation pile needs to be tested to test the stabilization effect of the foundation pile in the ground; the high-strain test of the foundation pile is generally detected by the hammering system for the high-strain detection of the foundation pile. [0003] Existing hammering system reference for high strain detection of foundation piles figure 1 and figure 2 , which includes a hoisting trolley 1, the hoisting trolley 1 includes a hoisting arm 11, and the hoisting arm 11 is provided with a hoisting cable 12; the lower end of the hoisting cable 12 is provided with a spring clip 13; Pull ropes 131 are respectively provided; the operator pulls the pull rope 131 to open the sprin...
