Description

Technical Field

[0001] The invention relates to the field of geotechnical engineering testing, and in particular to a deep hole sensor installation connecting rod quick disassembly and assembly auxiliary device and a use method thereof. Background Art

[0002] With the rapid development of urban transportation, the vibration induced by urban traffic loads represented by automobiles and rail transit is becoming more and more frequent. The vibration propagates in all directions through the soil. In serious cases, it will affect people's living and working comfort as well as the normal operation of precision instruments that are sensitive to vibration. Vibration will not only propagate horizontally on the surface of the soil, but also inside the soil. In order to understand the vibration level underground and the attenuation law of vibration with depth, and to provide technical support for the construction of underground projects, it is necessary to conduct vibration testing underground.

[0003] like Figure 1 The commonly used accessories for vibration testing include a vibration deep hole vibration sensor 1, several connecting rods 2 and a latch 3, etc. The general installation steps are: first drill a hole, and then place the deep hole vibration sensor 1 at the bottom of the hole. During the placement of the deep hole vibration sensor 1, in order to ensure that the angle can be adjusted, several connecting rods 2 connected together are usually used to place the deep hole vibration sensor 1 at the bottom of the hole, and then the angle of the deep hole vibration sensor 1 is adjusted by rotating the connecting rod 2. In order to ensure that the connecting rod 2 has a certain rigidity and prevent relative rotation between the connecting rods 2, the connecting rods 2 are usually connected one by one with latches 3. When connecting or removing the connecting rod 2, it is usually necessary to manually lift the connecting rod 2 with force and keep it still, and then connect or remove the connecting rod 2. Since the connecting rod 2 plus the deep hole vibration sensor 2 are particularly bulky, the connection process is time-consuming and laborious. Summary of the invention

[0004] In view of the problems existing in the installation of the above-mentioned existing deep hole vibration sensors, a simple-structured deep hole sensor installation connecting rod quick disassembly auxiliary device and a method of use are provided. The auxiliary device can clamp the connecting rod during the installation of the deep hole sensor, saving manpower and facilitating the disassembly of the connecting rod.

[0005] In order to solve the above technical problems, the present invention proposes a deep hole sensor installation connecting rod quick disassembly and assembly auxiliary device, comprising:

[0006] Base;

[0007] A column, the bottom end of which is assembled on the base; and

[0008] The cantilever beam has one end movably assembled on the top of the column and the other end is provided with a U-shaped slot corresponding to the connecting rod, and the U-shaped slot is used to limit the latch.

[0009] Furthermore, the base is a U-shaped base composed of three rods, and a plug hole is provided in the middle of the middle rod.

[0010] Furthermore, the column is a round tube, with plugs provided at both ends and the bottom end plugged into the socket.

[0011] Furthermore, the cantilever beam is a square tube, one end of which is provided with a mounting hole and is sleeved on a plug at the top end of the column.

[0012] The present invention also provides a method for using the above-mentioned deep hole sensor installation connecting rod quick disassembly and assembly auxiliary device, comprising the following steps:

[0013] 1) Drilling rigs are used to drill holes, and mud wall protection or casing wall protection is used according to soil conditions;

[0014] 2) Connect the deep hole vibration sensor to the first connecting rod, and then connect the second connecting rod to the first connecting rod through a pin;

[0015] 3) The deep hole sensor mounting connecting rod quick disassembly auxiliary device of the present invention (hereinafter referred to as "auxiliary device") is placed above the hole, and the cantilever beam of the auxiliary device can be rotated so that the U-shaped slot on it can be located directly above the hole;

[0016] 4) Place the deep hole vibration sensor into the hole and slowly lower it through the connecting rod until the pin on the connecting rod reaches the height of the cantilever beam. Rotate the cantilever beam so that the connecting rod is located in the U-shaped slot and blocks the pin.

[0017] 5) Connect the new connecting rod. After the connection is completed, temporarily rotate the cantilever beam to one side, and then continue to lower the connecting rod;

[0018] 6) Repeat the above steps until the deep hole vibration sensor is placed at the bottom of the hole;

[0019] 7) Disconnect the connecting rod from the deep hole vibration sensor and recycle the connecting rod. During the connecting rod recycle process, an auxiliary device is also used to first lock the pin connecting the connecting rod, and then disassemble the connecting rod.
