[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0027] As shown in the drawings, Figure 1 The hydraulic winch is an important component of the vibroflotation machine and comprises a hydraulic winch rope wheel 11, a steel wire rope 12, a vibroflotation pile rod 13, a steel wire sling 14 and a transverse traction beam bolt 15. The steel wire rope 12 is wound on the hydraulic winch rope wheel 11. One end of the steel wire rope 12 is hung with the steel wire sling 14 and is hung at the middle position of the steel wire sling 14. The vibroflotation pile rod 13 is fixed at both ends of the steel wire sling 14 through the transverse traction beam bolt 15.

[0028] The embodiment provides a system device for pile depth monitoring of a vibroflotation machine, which aims to detect the length of the steel wire rope 12 and simultaneously monitor the working depth of the vibroflotation pile rod 13 in real time.

[0029] Specifically, a system device for pile depth monitoring of a vibroflotation machine, also as shown in the drawings, Figures 1-4As shown, the device includes a roller 21, a roller shaft 22, a rotation sensor 23, a longitudinal connecting rod 24, a transverse connecting rod 25 and a base 26, wherein the roller 21 is in contact with the rolling surface of the hydraulic winch rope wheel 11 to achieve a rolling friction connection, the roller 21 includes a roller body and a hub (not shown in the figure) located at one end inside the roller 21 body and at one end outside the roller 21 body, the hub located outside the roller 21 body is fixedly connected with the roller shaft 22, the sensor rotating shaft 231 of the rotation sensor 23 is fixedly connected to one end of the roller shaft 22 away from the roller 21, so that the sensor rotating shaft 231 of the rotation sensor 23 is in a rotating connection with the roller 21 through the roller shaft 22; one end of the longitudinal connecting rod 24 is fixedly connected to the rolling surface of the roller shaft 22, the other end is fixedly connected to the base 26 through the transverse connecting rod 25, and the longitudinal connecting rod 24 and the transverse connecting rod 25 are arranged perpendicular to each other.

[0030] More specifically, the connection between the sensor rotating shaft 231 of the rotation sensor 23 and the roller shaft 22 is flexible connection, such as Figures 5-6 As shown, a flexible connecting piece 27 is arranged between the sensor rotating shaft 231 and the roller shaft 22, the flexible connecting piece 27 is made of flexible material such as rubber and is a four-key-shaped connecting piece, in order to adapt to the shape of the flexible connecting piece 27, one end of the sensor rotating shaft 231 is in a two-key sleeve shape, one end of the roller shaft 22 is also in a two-key sleeve shape, and the size of the two-key sleeve of the sensor rotating shaft 231 and the roller shaft 22 is adapted to the size of the four-key of the flexible connecting piece 27. When flexibly connected, one end of the two-key sleeve of the sensor rotating shaft 231 is fitted into two of the four-key of the flexible connecting piece 27, one end of the two-key sleeve of the roller shaft 22 is fitted into the other two of the four-key of the flexible connecting piece 27, and the three are fixed by bolts. By arranging the flexible connection between the rotation sensor 23 and the roller shaft 22, not only the sensor can be easily disassembled and replaced, but also the relative displacement between the sensor rotating shaft 231 and the roller shaft 22 can be allowed, the vibration and noise during work can be reduced, and the safety and stability of the device can be improved.

[0031] More specifically, the connection between the roller shaft 22 and the roller 21 is (not shown in the figure): the roller shaft 22 passes through the hub on the roller 21 as a through shaft as a whole, and one end of the roller shaft 22 passes out of the hub on the roller 21, and the roller shaft 22 is provided with a bolt that can slide along its axial direction, and the fixed connection of the roller shaft 22, the roller 21 and the sensor rotating shaft 231 is realized by the sliding bolt. By sliding the bolt and changing its fixed position, the distance between the sensor rotating shaft 231 and the roller 21 can be changed.

[0032] More specifically, the whole device is in an inclined state of 45 degrees to ensure good contact between the roller 21 and the hydraulic winch rope wheel 11.

[0033] More specifically, the longitudinal connecting rod 24 is an O-shaped bracket rod.

[0034] More specifically, as shown in Figures 1-4 , the device further comprises a spring 28, one end of which is fixed to the base 26 through the transverse connecting rod 25, and the other end is pulled to one end of the longitudinal connecting rod 24 close to the sensor rotating shaft 231. The function of the spring 28 is to prevent the drum 21 and the hydraulic winch rope wheel 11 from relaxing under the action of its elastic traction force.

[0035] More specifically, as shown in Figure 4 , the base 26 is a semicircular clamp structure, which is fixed to the working surface by bolts, and the semicircular clamp is fixed to the transverse connecting rod 25 by fastening bolts 29. Among them, the position points of the semicircular clamp, the transverse connecting rod 25 and the fastening bolts 29 are taken as reference points.

[0036] The specific monitoring process of the utility model is:

[0037] First, calibration; take the position points of the semicircular clamp, the transverse connecting rod 25 and the fastening bolts 29 as reference points, and calibrate the initial value of the rotary sensor 23;

[0038] Second, pile depth monitoring: when the hydraulic winch is working, the hydraulic power on it drives the hydraulic winch rope wheel 11 to start rotating. With the rotation of the rope wheel, the steel wire rope 12 is gradually released from the rope wheel and lowered. In this process, the vibroflotation pile rod 13 is tightly connected to the end of the steel wire rope 12, so as the steel wire rope 12 is lowered, the vibroflotation pile rod 13 also slowly descends and works deep underground. Since the hydraulic winch rope wheel 11 is mechanically connected with the roller shaft 22 and the drum 21, when the hydraulic winch rope wheel 11 rotates, the drum 21 rotates synchronously with the rope wheel, and then the rotation is transmitted to the sensor rotating shaft 231 of the rotary sensor 23 through the roller shaft 22. The rotary sensor 23 accurately senses and records the circumference corresponding to each rotation of the sensor rotating shaft 231. Since the lowering depth of the vibroflotation pile rod 13 is directly related to the length of the steel wire rope 12, and the length of the steel wire rope 12 can be calculated by the number of rotations of the hydraulic winch rope wheel 11 and its circumference, therefore, by using the number of rotations of the rotating shaft recorded by the rotary sensor 23 and combining the known rotating circumference, the lowering depth of the vibroflotation pile rod 13 can be accurately calculated.

[0039] The vibroflotation machine pile depth monitoring process of the embodiment can detect the length of the steel wire rope 12, and can monitor the working depth of the vibroflotation pile rod 13 in real time. The whole vibroflotation machine pile depth monitoring system device has simple structure and is easy to operate, which is conducive to large-scale application.

[0040] It should be noted that the rotation sensor in the embodiment is prior art, and the application does not involve improvement thereof, because the specific structure and working principle thereof will not be described herein again. In addition, the calculation of the working depth of the vibroflotation pile rod can be obtained by the control system, which is also prior art, and the application will not be described herein again.

[0041] The preferred embodiments of the utility model are described above, and the protection scope of the utility model is not limited to the above-mentioned embodiments only, and any technical solution belonging to the idea of the utility model belongs to the protection scope of the utility model. It should be noted that for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the utility model should be considered as the protection scope of the utility model.
