Description

Technical Field

[0001] The utility model relates to the technical field of probe equipment, in particular to a vehicle-mounted probe. Background Art

[0002] The cone penetration test uses a certain amount of hammer kinetic energy to drive a cone of a certain specification into the soil. The changes in soil layers are determined based on the resistance of the cone when driven into the soil. The soil layers are mechanically stratified and the physical and mechanical properties of the soil layers are determined. An engineering geological evaluation of the foundation soil is then made. The resistance of the soil is usually expressed by the number of blows required to drive a certain distance into the soil.

[0003] At present, when dynamic probing is used to conduct on-site testing of the bearing capacity of soil foundation, the test equipment used is relatively simple. The on-site operation is that one person holds the probing rod, and the other person holds the hammer with both hands and lifts it up along the probing rod. When it reaches the required height, the hammer is released and the hammer falls naturally to perform the test. Due to the limitations of the test equipment, the hammer may fall during the test, which poses a safety hazard. The test method is slow, which seriously affects the progress of the test and wastes manpower, and the labor intensity is high. On the other hand, the number of hammer strikes each time needs to be counted by a person, which may cause counting errors, thereby affecting the calculation results. The height of the hammer must be raised to a certain height as specified in the TB10081-2018 (Railway Engineering Geology In-situ Test Procedure). Due to safety considerations, it is not taken seriously during the test process. The hammer is released before it reaches the specified height, which is not good for the stability of the drop hammer, thereby affecting the test detection data. When the test is completed and the rod is lifted, it needs to be completed with the help of other equipment, and the weight of the entire equipment is large, which is very inconvenient in the transportation, installation and test operation of the equipment.

[0038] like Figure 1 and Figure 4 As shown, the first lifting member 17 and the second lifting member 18 both include a lifting hydraulic cylinder 29 and a sprocket 31 group arranged at the output end of the lifting hydraulic cylinder 29, the sprocket 31 group includes a connecting column 30 and sprockets 31 rotatably arranged at both ends of the connecting column 30, and the sprocket 31 is provided with a chain 32 that cooperates with each other, and both ends of the chain 32 are provided with a threaded column 33, which are respectively connected to the control board 10 and the frame 4, and the control board 10 and the frame 4 are provided with internal threaded holes connected to the threaded column 33, and the tension of the chain 32 can be adjusted according to the needs of use.

The two lifting hydraulic cylinders 29 are respectively provided with synchronization valves to ensure the synchronous operation of the first lifting member 17 and the second lifting member 18.

[0040] In order to maintain the stability of the device, a linear guide rail 36 is provided between the control board 10 and the frame 4 . There are two linear guide rails 36 , which are respectively provided at two ends of the control board 10 .

[0041] Working principle: When the vehicle-mounted prober provided by the utility model needs to drive the probe rod 8 into the soil, the lifting plate 22 on the lifting member 19 is removed and placed on the frame 4 below. The prober body 1 is perpendicular to the ground. According to the position of the prober body 1, the height of the support seat 5 is adjusted, and then the probe rod 8 is installed on the connecting head 28 under the guide rod 7, and the probe rod 8 is aligned with the position to be driven into the soil, and the penetration operation of the probe rod 8 is started. Figure 6 As shown: the controller starts the first lifting member 17 and the second lifting member 18, so that the control panel 10 is close to the core hammer 6, the core hammer 6 lifts up the second induction member 15, and is sucked by the electromagnet 16 at the same time, the bottom switch 13 detects the second induction member 15, and transmits the signal to the controller, the controller starts the first lifting member 17 and the second lifting member 18, when the lifting hydraulic cylinder 29 is lifted, the connecting column 30 is lifted up respectively, so that the two sprockets 31 on the connecting column 30 pull the chain 32 to drive the control panel 10 to rise upward, and the core hammer 6 moves along the guide rod 7 under the suction of the electromagnet 16. The hammer 6 then moves downwards and when it reaches the position of the first sensing element 14 on the guide rod 7, the counting switch 11 and the top switch 12 respectively detect the first sensing element 14, the counting switch 11 transmits a signal to the controller, the number of hammering increases by one, and the top switch 12 transmits a signal to the controller at the same time. The controller cuts off the power to the electromagnet 16, and the core hammer 6 quickly slides down along the guide rod 7 and hammers the stop ring 9. At the same time, gravity is transmitted to the feeler 8 under the stop ring 9, so that the feeler 8 continues to penetrate underground. The above operation is repeated until the feeler 8 penetrates into the soil to the required position.

[0042] When it is necessary to pull out the sounding rod 8 in the soil, the lifting plate 22 on the lifting member 19 is installed on the adjusting columns 23 at both ends, and the controller starts the first lifting member 17 and the second lifting member 18. The lifting plate 22 is limited below the stop ring 9. As the control board 10 is lifted, the part above the stop ring 9 is also lifted. At the same time, the sounding rod 8 under the stop ring 9 connected to the guide rod 7 is also lifted, so as to realize the removal operation of the sounding rod 8 penetrated into the ground.
