Description

Technical Field

[0001] The utility model relates to the technical field of drilling probe machines, in particular to a hammering times controller. Background Art

[0002] The drilling test, also known as the light dynamic penetration test, is to use a standard diameter drilling rod marked with a scale to vertically strike into the foundation soil layer by mechanical or manual means, using a hammer head with a calibrated weight located directly above the drilling rod. The number of hammer strikes required for the drilling rod to enter the foundation soil layer to be detected 300mm each time is used to detect the hidden structure in the soil layer or roughly estimate the allowable bearing capacity of the soil layer, and the hardness of the soil can be judged accordingly. When conducting drilling, manual counting is required, which requires recording the number of hammer strikes and checking the hammer strike depth. Due to the large number of times and the high frequency, one worker can only look after one drilling machine at the same time, which is labor-intensive and inaccurate counting is prone to misrecording and omission, and cannot accurately reflect the actual soil conditions.

[0003] The patent with the announcement number "CN212001011U" is named: An automatic counting device for the number of hammer strikes of a drilling probe. The public document solves the above problems, but the shortcomings of the public document are: when the spring rebounds, the rebound force of the spring will drive the baffle to jump repeatedly, which will cause the infrared transmitter to repeatedly monitor the baffle, affecting the accuracy of the hammer strike count. Based on this, the utility model designs a hammer strike controller to solve the above problems. Utility Model Content

The staff first pushes the shell 4 so that the roller 3 moves the probe 5 to the working area, and then turns on the first hydraulic pump 802. The first hydraulic pump 802 discharges the hydraulic oil in the hydraulic box 801 from the first Y-shaped tube 9 into the guide hole 701, so that the hydraulic oil squeezes the slide bar 702 to push the mounting plate 703 together with the mounting rod 704, the support plate 705 and the hammer head 706 to move upward along the direction of the guide hole 701, thereby expanding the distance between the hammer head 706 and the connecting plate 6, and then by using the second hydraulic pump 803, the hydraulic oil in the guide hole 701 is discharged from the second Y-shaped tube 10 into the hydraulic box 801, and through the action of the slide bar 702, the mounting plate 703, the mounting rod 704, the support plate 705 and the hammer head 706's own gravity, the hammer head 706 falls freely and then strikes the connecting plate 6, so that the connecting plate 6 together with the probe 5 is inserted into the ground.

[0032] According to the operation method in Example 1, when the support plate 705 moves upward along the direction of the housing 4, the support plate 705 together with the ejector pin 16 exerts a squeezing force on the travel switch 15, thereby turning off the first hydraulic pump 802 and turning on the second hydraulic pump 803.

When the hammer head 706 strikes the probe rod 5, the hammer head 706 cuts off the path for the first infrared sensor 18 and the second infrared sensor 19 to monitor each other. The second hydraulic pump 803 is turned off, and the first hydraulic pump 802 is turned on. In the above manner, the hammer head 706 is in a reciprocating up and down motion mode to hit the probe rod 5, and the counter 11 accurately records the number of each hit. The staff can check the scale 14 to know the depth of the probe rod 5 inserted into the ground. In addition, the staff can screw the limit rod 13 into the ground to ensure the stability of the probe rod 5 during the insertion of the ground. When the device is used, the probe rod 5 is pulled out of the ground, and the screw pin 23 is screwed into the socket 24 to lock the position of the probe rod 5 removed from the ground.
