[0024] A device for counting the amount of tamping machine tamping, comprising a tamping machine body 4 and a counting system 1. The tamping machine body 4 comprises a frame 401, a hydraulic system 402, a winch 403, a tamping hammer 404, a traveling mechanism 405, a control system 406, a hook 408, and a cab 409. The winch 403 is provided with a wire rope 407, one end of which is connected to the hook 408. The frame 401 is provided with an RTK system 2. The tamping hammer 404 is lifted to a certain height by the winch 403, at which time an encoder 101 records the initial number of turns of the wire rope 407. Subsequently, the tamping hammer 404 falls under the action of gravity to perform a tamping operation, and is then lifted again by the winch 403. The encoder 101 records the number of turns at this time. According to the time of two adjacent lifts recorded by the encoder 101, The difference in the number of turns, combined with the diameter of the wire rope 407, uses the formula h=3.14*d(a'-a) to calculate the tamping amount of two adjacent times. This cycle is repeated, and the total tamping amount is accumulated by adding up the tamping amount each time to obtain the total tamping amount. At the same time, the RTK system 2 provides real-time precise positioning measurement, the monitoring mechanism 102 monitors the acceleration and displacement changes of the rammer 404 during the tamping process, and the lateral pressure sensor 103 measures the tension change of the wire rope 407. These data are combined with the data of the encoder 101 to improve the accuracy and reliability of the tamping amount calculation. The control system 406 receives and processes these data, and displays the tamping amount, position information and machine status on the display screen in real time.

The encoder 101 is set on the steel The circumference of the wire rope 407 is used to record the number of turns each time, which is convenient for calculating the tamping amount. The lateral pressure sensor 103 is set 500mm above the hook 408 to measure the tension change of the wire rope 407. It can fully record the key information such as the number of turns of each movement of the rammer 404 and the tension change, so as to accurately calculate the tamping amount. The setting of the encoder 101 can record the number of turns of the wire rope 407 in real time, and the lateral pressure sensor 103 can measure the tension change of the wire rope 407. The combination of the two improves the accuracy and reliability of the calculation of the tamping amount. The control system 406 is electrically connected to the counting system 1 and the RTK system 2, and is used to receive and process the information from the counting system 1 and RTK system 2 data, thereby achieving accurate control and recording of the tamping amount. The control system 406 also includes a display screen for real-time display of the tamping amount, position information and machine status. The control system 406 is electrically connected to the counting system 1 and the RTK system 2, achieving accurate control and recording of the tamping amount. At the same time, the control system 406 also includes a display screen that can display the tamping amount, position information and machine status in real time, improving the convenience and intuitiveness of operation. This design allows operators to understand the working status and tamping amount data of the machine at any time, so as to make more accurate decisions. The monitoring mechanism 102 also includes an acceleration sensor and a displacement sensor , used to monitor the acceleration and displacement changes of the rammer 404 during the compaction process, and the data of the monitoring mechanism 102 are combined with the data of the encoder 101 and the lateral pressure sensor 103 to improve the accuracy of the calculation of the tamping amount. It can monitor the acceleration and displacement changes of the rammer 404 during the compaction process.

[0026] The working process of the utility model: When using the device for counting the amount of tamping machine, the basic principle is as follows:
[0027] The first lifting distance is b and the number of encoder turns is a
[0028] The second lifting distance is b1 and the corresponding encoder number of turns is a1
[0029] And so on
[0030] The first tamping amount h1 is: h1 = b1-b = 3.14*d(a1-a)
[0031] The second tamping amount h2 is: h2 = b2 - b1 = 3.14 * d (a2 - a1)
[0032] Where d is the diameter of the wire rope 407
[0033] And so on
[0034] The total tamping amount h = h1 + h2 + h3..., the calculation formula here is h = 3.14*d(a'-a), where a' and a represent the number of encoder turns during two adjacent lifts, respectively, and h represents the tamping amount during two adjacent lifts. Specifically, when the encoder 101 rotates one circle, the distance that the wire rope 407 is lifted or lowered is the circumference πd of the wire rope 407. Therefore, by comparing the difference a'-a between the number of encoder turns during two adjacent lifts, the difference in the lifting distance of the wire rope during two adjacent lifts, that is, the tamping amount, can be calculated. The overall process is to lift the rammer 404 to a certain height through the winch 403. At this time, the encoder 101 records the initial number of turns of the wire rope 407. Subsequently, the rammer 404 falls under the action of gravity to perform a tamping operation, and is then lifted again by the winch 403. The encoder 101 records the number of turns at this time. According to the difference in the number of turns between two adjacent lifts recorded by the encoder 101, combined with the diameter of the wire rope 407, the formula h = 3.14*d(a'-a) is used to calculate the tamping amount of two adjacent lifts. This cycle is repeated, and the total tamping amount is accumulated by adding up the tamping amount each time to obtain the total tamping amount. At the same time, the RTK system 2 provides real-time precise positioning measurement, the monitoring mechanism 102 monitors the acceleration and displacement changes of the rammer 404 during the tamping process, and the lateral pressure sensor 103 measures the tension changes of the wire rope 407. These data are combined with the data from the encoder 101 to improve the accuracy and reliability of the tamping amount calculation. The control system 406 receives and processes these data, and displays the tamping amount, position information and machine status on the display screen in real time. It can also connect to the remote monitoring system through a wireless network to realize real-time data transmission and remote monitoring.
