[0025] Reference Figure 1-5As shown, it is a preferred embodiment provided by the utility model.

[0026] The supporting pile displacement measuring device comprises a hanging hammer 1, a hanging rope 2 and a plurality of distance sensors 5. The upper part of the hanging rope 2 is connected to the crown beam of the supporting pile 3, the lower part of the hanging rope 2 is connected to the hanging hammer 1, and the hanging rope 2 is arranged vertically; each distance sensor 5 is respectively mounted on the hanging rope 2, and along the length direction of the hanging rope 2, each distance sensor 5 is arranged at equal intervals. The distance sensor 5 is used to measure the horizontal distance between the distance sensor 5 and the supporting pile 3, and the horizontal displacement of the supporting pile 3 is fed back based on the displacement difference between different distance sensors 5.

[0027] In the above-mentioned supporting pile displacement measuring device, when measuring the horizontal displacement of the supporting pile 3, the hanging hammer 1 is lowered by the hanging rope 2, and then the distance sensor 5 measures the horizontal distance to the supporting pile 3. Then, the horizontal displacement of the supporting pile 3 is obtained by the horizontal distance difference between the upper and lower distance sensors 5. In this way, the measurement can be reused to reduce the measurement cost. At the same time, the horizontal displacement measurement of the supporting pile 3 can be completed by simply lowering the hanging hammer 1. The operation is simple and convenient, which greatly facilitates the horizontal displacement measurement of the supporting pile 3.

[0028] The distance sensor 5 uses the principle of “time of flight method” to measure the distance to the supporting pile 3 .

[0029] The distance sensor 5 calculates the distance to the object by emitting an energy beam which is reflected by the measured object and calculating the time from the emission of the beam to the reflection of the object.

[0030] The energy beam emitted by the distance sensor 5 may be ultrasound, laser, infrared light, radar, etc.

[0031] The suspension rope 2 has a plurality of rope grooves 21, and the distance sensor 5 is installed in the rope grooves 21. The suspension rope 2 is provided with a plurality of measuring covers 22, and each measuring cover 22 is arranged in a one-to-one correspondence with each rope groove 21. The measuring cover 22 is arranged to be light-transmissive, and the measuring cover 22 covers the rope grooves 21. The distance sensor 5 is arranged opposite to the measuring cover 22.

[0032] In this way, under the action of the rope groove 21 , the distance sensor 5 is arranged, and under the action of the measuring cover 22 , the distance sensor 5 is protected. Meanwhile, the measuring cover 22 will not affect the distance measurement of the distance sensor 5 .

[0033] The rope grooves 21 are arranged at equal intervals, so that the support piles 3 can be measured at equal intervals, which is helpful for subsequent data analysis. At the same time, the horizontal displacement of the support piles 3 at different positions can be determined, and it can be directly clear which horizontal position is the most serious.

[0034] The rope groove 21 has an inner groove wall, which is arched inward and arranged in an arc shape. The surface of the distance sensor 5 is arranged in an arc shape. The distance sensor 5 and the inner groove wall are arranged flat and in conflict with each other. The distance sensor 5 is arranged in the center. In this way, the stability of the distance sensor 5 is improved. At the same time, it is convenient for the distance sensor 5 to be arranged in the center, and the lifting rope 2 to be arranged vertically, thereby ensuring the accuracy of the horizontal position measurement of the support pile 3.

[0035] The mid-point perpendicular line of the distance sensor 5 is arranged to coincide with the mid-point perpendicular line of the suspension rope 2 , so that the suspension rope 2 is arranged to be suspended vertically, thereby ensuring the accuracy of the horizontal position measurement of the support pile 3 .

[0036] The suspension rope 2 has a longitudinal groove 23, which is extended along the length direction of the suspension rope 2 and connected to each rope groove 21. The longitudinal groove 23 is used to install a conducting wire, and each distance sensor 5 is connected to the conducting wire. Under the action of the conducting wire, each distance sensor 5 is powered on and data transmission of the distance sensor 5 is achieved.

[0037] Furthermore, a battery is provided inside the distance sensor 5 to realize independent power supply of the distance sensor 5 .

[0038] Furthermore, the rope groove 21 is provided with a transmission module, which is arranged in data communication with the distance sensor 5 . The transmission module is used for wireless data transmission to achieve transmission of measurement data of the distance sensor 5 , which facilitates acquisition of measurement data.

[0039] The transmission module transmits via Bluetooth, WIFI, or 3G, 4G, or 5G networks.

[0040] The displacement measuring device of the supporting pile 3 comprises a rope fixture 4, which is assembled or separated from the crown beam of the supporting pile 3; under the action of the rope fixture 4, the assembly of the suspension rope 2 is realized, which is convenient for the subsequent hanging of the suspension hammer 1.

[0041] The rope fixing device 4 includes a rope fixing frame, a longitudinal wheel 41 and a winding wheel 42. The rope fixing frame and the crown beam of the supporting pile 3 are assembled or separated. The longitudinal wheel 41 and the winding wheel 42 are movably mounted on the rope fixing frame respectively. The lifting rope 2 passes around the longitudinal wheel 41 and the winding wheel 42 respectively. The winding wheel 42 is used to wind up or release the lifting rope 2. The longitudinal wheel 41 is arranged above the supporting pile 3, and the longitudinal wheel 41 and the supporting pile 3 are staggered.

[0042] In this way, the winding or releasing of the suspension rope 2 is achieved through the winding wheel 42, so that the lowering of the suspension rope 2 during measurement is convenient, and the recovery of the suspension rope 2 after the measurement is completed is convenient; under the action of the longitudinal wheel 41, the direction of the suspension rope 2 is adjusted, so that the suspension rope 2 is converted into a vertical hanging state, and then the suspension hammer 1 is in a vertical hanging state, thereby ensuring the accuracy of the measurement.

[0043] The rope fixing device 4 includes a winding and discharging motor, which is installed on the rope fixing frame.

[0044] The displacement measuring device of the supporting pile 3 comprises a plurality of casing parts, each casing part is arranged in one-to-one correspondence with each distance sensor 5; and the casing parts are arranged in a buckling manner with the suspension rope 2.

[0045] In this way, when the measurement is completed and the lifting rope 2 is recovered, the shell part is buckled with the lifting rope 2, and the distance sensor 5 is protected by the shell part, and the measuring cover 22 is protected to avoid scratches and other damages to the measuring cover 22, so as to avoid affecting the horizontal displacement measurement of the supporting pile 3.

[0046] The hanging hammer 1 is arranged in a cone shape, and the cross-sectional area of ​​the hanging hammer 1 is gradually reduced along the direction away from the hanging rope 2; thus, it is convenient for the hanging hammer 1 to be suspended vertically and to apply a downward force, thereby ensuring that the hanging rope 2 is arranged vertically and the measurement of the distance sensor 5 is ensured.

[0047] The center of the lifting rope 2 and the hanging hammer 1 are arranged correspondingly, so that the lifting rope 2 is arranged vertically, thereby ensuring the accuracy of the horizontal position measurement of the supporting pile 3.

[0048] The displacement measuring device of the supporting pile 3 includes an inclination sensor 6, which is installed on the hanging hammer 1 and is used to detect the verticality of the hanging hammer 1 in a hanging state; in this way, under the action of the inclination sensor 6, after the hanging hammer 1 is placed vertically, the distance sensor 5 performs horizontal displacement measurement to ensure the accuracy of the horizontal position measurement of the supporting pile 3.
