Detailed Implementation

[0020] The present application will be further described below with reference to the accompanying drawings. The structure and principle of the present application are very clear to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Figure 2 for Figure 1 A schematic diagram of the pressure detection device in the illustrated embodiment. Figure 3 for Figure 1 A partial cross-sectional view of the pressure detection device in the illustrated embodiment.

[0022] Combination Figures 1 to 5 It is understood that the smart tamping rod of this application includes a handle 1 and a tamping rod body 3.

[0023] The handle 1 houses a counting and depth display control chamber 412. The outer wall of the counting and depth display control chamber 412 is equipped with a counting display screen 401 and a counting switch 407. A controller 410 is located inside the counting and depth display control chamber 412. The controller 410 records the number of times the intelligent tamping rod is inserted, the counting display screen 401 displays the number of insertions, and the counting switch 407 resets the number of insertions to zero. One end of the tamping rod body 3 is used for insertion, and the other end is connected to the handle 1. Multiple pressure detection devices 2 are arranged along the length of the tamping rod body 3. Each pressure detection device 2 includes a pressure sensor 201, which detects the pressure borne by the tamping rod body 3. The counting and depth display control chamber 412 is electrically connected to the pressure detection devices 2, which detect the pressure borne at multiple locations on the tamping rod body 3. The controller 410 records the number of insertions of the intelligent tamping rod and calculates the insertion depth based on the pressure borne.

[0024] When the intelligent tamping rod is inserted into the concrete, the pressure applied by the concrete to the tamping rod body 3 will change with the tamping depth. The pressure detected by the pressure detection device 2 is transmitted to the controller 410 located in the counting and depth display control chamber 412. The controller 2 will calculate the depth of the pressure detection device 2 in the concrete based on the pressure, which is the tamping depth.

[0025] The pressure detection device 2 can be set with a pressure threshold. When the pressure received by the pressure detection device 2 at a certain depth exceeds the pressure threshold, the controller 2 will record one tamping number, thereby realizing intelligent statistics of the tamping number.

[0026] Since the slump test requires tamping three layers of concrete, this application provides three corresponding pressure testing devices 2. In other optional embodiments, those skilled in the art can also select different numbers of pressure testing devices 2. It should be noted that the tamping depth in this application specifically refers to the depth of the pressure testing device 2 in the concrete, not the depth of the bottom of the intelligent tamping rod.

[0027] In addition, the handle 1 is equipped with a wire storage compartment 101, the tamping rod body 3 is equipped with a wire guide tube 5, and the pressure detection device 2 also includes a sensor interface 202 located inside the pressure sensor 201. The counting and depth display control compartment 412, the wire storage compartment 101, the wire guide tube 5 and the sensor interface 202 are connected in sequence by wires.

[0028] The pressure sensor 201 includes a bottom pressure sensor, a middle pressure sensor, and a top pressure sensor located at the bottom, middle, and top of the tamping rod body 3, respectively. The outer wall of the counting and depth display control chamber 412 is also equipped with bottom sensor indicator lights 402, middle sensor indicator lights 403, and top sensor indicator lights 404, used to monitor the tamping depth of the intelligent tamping rod. The counting and depth display control chamber 412 also contains a power supply 409 and a relay block 405, which are connected sequentially to the power supply 409 to provide power to the intelligent tamping rod.

[0029] Specifically, the grip 1 includes a wire storage compartment 101, a display device mating slot 102, and a switch slot 103. The grip 1 is hollow, and the display device mating slot 102 is located at the lower end of the grip 1. The wire storage compartment 101 stores the wires connecting the thin-film pressure sensor 201 and the power supply 409. The display device mating slot 102 mates with the grip mating slot 408, and both are tenon-and-mortise joint structures.

[0030] In this embodiment, the pressure sensor 201 can be a thin-film pressure sensor 201. The thin-film pressure sensor 201 is connected to the wire in the wire guide tube 5 through the sensor interface 202. The grip 1 is provided with a counting display screen 401, a bottom sensor indicator light 402, a middle sensor indicator light 403, a top sensor indicator light 404, a relay block 405, a power switch 406, a counting switch 407, a grip mating groove 408, a power supply 409, a controller 410, and a wire outlet 411. The counting display screen 401 is located at the top of the grip 1, and the counting display screen 401 only displays numbers, with the number range being 1-30.

[0031] When the bottom pressure sensor detects the depth of the concrete being tamped by the intelligent tamping rod to the bottom, the bottom sensor indicator light 402 lights up and is counted by the controller 410. The number of tampings is displayed on the counting display screen 401. After the intelligent tamping rod is lifted, all indicator lights go out. When starting the second layer, the counting switch 407 is pressed to reset the count.
