Embodiment 1
[0038] Such as figure 1 and 2 As shown, the device consists of 1-guide pulley, 2-guide pulley support, 3-carrying platform, 4-telescopic outrigger, 5-support foot, 6-ground anchor to be detected, 7-fixed ground anchor, 8-wire rope , 9-tension meter, 10-lean block.
[0039] The present invention provides an anchor pullout force detection test device, which includes: a sliding mechanism, a telescopic support mechanism, a steel wire rope 8, a force measuring device and a lifting device;
[0040] The telescopic support mechanism has a certain height, and the sliding mechanism is rotatably arranged on the upper part of the telescopic support mechanism;
[0041] After the steel wire rope 8 is connected to the ground anchor 6 to be detected, it crosses the upper part of the sliding mechanism, and then connects one end of the force measuring device and the lifting device in sequence; the other end of the lifting device is fixed to the ground;
[0042] The force-measuring device tes...
Embodiment 2
[0055] Based on the same inventive concept, the present invention also provides a ground anchor pullout force detection test method, which is characterized in that it includes:
[0056] Adjusting the telescopic support mechanism to a certain height, the sliding mechanism is rotatably arranged on the upper part of the telescopic support mechanism;
[0057] One end of the wire rope 8 is connected to the ground anchor 6 to be detected, so that the wire rope 8 is connected to the force measuring device and the lifting device sequentially over the sliding mechanism, and the other end of the lifting device is fixed to the ground;
[0058] Under the tightening force provided by the lifting device, the force measuring device tests the pullout resistance of the ground anchor 6 to be tested.
[0059] The adjustment of the telescopic support mechanism to a certain height includes:
[0060] Install and fix the three telescopic outriggers 4 of the telescopic support mechanism in a nested ...

Abstract
The invention relates to a ground anchor pulling resistance detection test device. The device comprises: a sliding mechanism, a telescopic supporting mechanism, a steel wire rope (8), a force measuring apparatus and a hoisting apparatus, the telescopic supporting mechanism has a certain height, the sliding mechanism is rotatably arranged at the upper part of the telescopic supporting mechanism, the steel wire rope (8) is connected to a to-be-detected ground anchor (6), then crosses the upper part of the sliding mechanism and is sequentially connected to the force measuring apparatus and one end of the hoisting apparatus, the other end of the hoisting apparatus is fixed to the ground, and the force measuring apparatus tests the pulling resistance of the to-be-detected ground anchor (6) under a tightening force provided by the hoisting apparatus. According to the device, the pulling resistance load is transferred to the ground through the sliding mechanism, a load value can be loaded andread on the ground, also the telescopic supporting mechanism is adopted, the height can be independently adjusted, and the device can adapt to complex terrains of test places.
Description
technical field [0001] The invention relates to the technical field of ground anchor pullout force detection test, in particular to a ground anchor pullout force detection test device and method. Background technique [0002] The ground anchor is a temporary anchoring tool for power transmission line construction, which is used to fix the winch, stretcher, steering pulley and temporary guy wire, etc. The ground anchor can be divided into rigid rod ground anchor, ship type ground anchor (plate type ground anchor) anchor); [0003] When the rigid rod ground anchor is used, the ground anchor is screwed into the ground by rotation, and the pull-out force is generated through the interaction between the self-weight of the soil and the shear force of the soil layer and the helical blade of the ground anchor to achieve the fixing effect; the ship-type ground anchor (plate-type ground anchor ) When in use, bury the ground anchor in a ground anchor pit of a certain depth, lead out t...
