Description

Technical Field

[0001] The present invention relates to the technical field of support tooling, and in particular to a multi-purpose support tooling for field testing and its usage method. Background Art

[0002] In field testing experiments, a variety of high-precision sensors are required for data acquisition, including free-field pressure sensors, acceleration sensors, heat flux density sensors, thermocouple sensors, etc. A variety of sensors are freely combined according to the test needs, and are respectively arranged at different positions and different distances. At the same time, the data collected by the sensors is transmitted to the rear of the test experiment through cables. Therefore, high requirements are put forward for the fixed support, random layout, and cable protection of various types of high-precision sensors.

[0003] Currently, there is a lack of a multi-purpose support tooling for field testing that can meet the following functions: First, the tooling can be fixedly supported at any position to resist impacts such as wind force; second, the tooling can install multiple high-precision sensors that do not interfere with each other during operation. Summary of the Invention

[0004] (I) Technical Problem to be Solved

[0005] The technical problem to be solved by the present invention is to provide a tooling that can randomly arrange and fixedly support high-precision sensors during field testing experiments, so as to resist the impact of factors such as wind force, obtain test data of multiple high-precision sensors, and provide data support for field testing experiments.

[0006] (II) Technical Solution

[0007] The purpose of the present invention is to provide a multi-purpose support tooling for field testing and its usage method. To achieve this purpose, the present invention adopts the following technical solutions:

[0008] The present invention provides a multi-purpose support tooling for field testing, which is composed of support feet, support rods, and sensor clamps.

[0009] The support feet are composed of 3 L-shaped forks, and the 3 L-shaped forks are circumferentially distributed at the bottom end of the tooling and connected to the ground.

[0010] One end of the fork is an external thread, which is connected to the internal thread hole of the support rod, and a fastening nut is used to ensure that the fork is perpendicular to the ground when connected. The other end of the fork is a tapered head, which is inserted into the ground and fixedly connected to the ground.

[0011] The support rod is composed of multiple tubular long rods. The bottom end of the long rod is connected to the L-shaped fork, and the top end is connected to the sensor clamp.

[0012] The support rod is composed of a lower vertical rod close to the ground and an upper vertical rod close to the top. The bottom end of the lower vertical rod is connected to the L-shaped fork through a threaded hole. Multiple gear parts are sequentially arranged from top to bottom along the vertical direction at the top end of the lower vertical rod. Each gear part is welded with a nut and provided with a through groove at its corresponding position, and is tightly connected to the upper vertical rod through a screw. When the upper vertical rod is inserted into the lower vertical rod at different depths, the multiple gear parts can ensure the connection strength of the support rod.

[0013] The upper vertical rod is a tubular long rod, and a groove is opened on one side of the upper vertical rod for placing the data output cable of the sensor.

[0014] The sensor fixture is composed of a central sleeve and sensor toolings at both ends, is connected to the upper vertical rod, and installs high-precision sensors required for testing through the interfaces of the sensor toolings.

[0015] The central sleeve is welded with a nut and provided with a through groove at its corresponding position, and is tightly connected to the upper vertical rod through a screw. According to the types of sensors required for testing, corresponding connection methods are added to the central sleeve. According to the required layout height of the sensors, the central sleeve is installed at different positions on the upper vertical rod.

[0016] The beneficial effects of the present invention are as follows: The present invention provides a multi-purpose support tooling for field testing. The design of the L-shaped fork in the support feet provides a stable connection between the tooling and the field test ground at different orientations and distances during field test experiments, and resists the impact effects such as wind force to a certain extent; through the multi-section support rod with adjustable height, the test requirements of different sensors at a certain range of horizontal heights are realized; through the flexible combination and series installation methods, the test requirements of multiple sensors at the same orientation and distance during the test experiment are realized; through the tubular and grooved design of the upper vertical rod, the cable protection under the test environment is satisfied.

[0017] Therefore, the multi-purpose support tooling for field testing provided by the present invention can solve the difficulties in the current field test experiments, that is, there is no general support tooling to realize the fixed support, random layout, and cable protection required for data collection by multiple high-precision sensors.

[0018] (III) Beneficial Effects

[0019] 1. The multi-purpose support tooling for field testing can be inserted into the ground and fixed for support under various ground conditions in the field, including environments such as gobi, desert, and mud; at the same time, it is modularly designed, can be operated by a single person, and is convenient for use, disassembly, packaging, and transportation, and is easy to use.

[0020] 2. The multi-purpose support tooling for field testing adjusts its height through the multi-section tubular long rod of the support rod to meet the requirements of different sensor tests. At the same time, the support rod can be arranged with multiple sensors in series from top to bottom, meeting the test requirements of obtaining data from multiple sensors at the same position in field testing.

[0028] The present invention will be further described in detail below with reference to the drawings and embodiments. It should be noted that in the specific embodiments described herein, the support rod is composed of two sections of long rods, and only one type and one sensor fixture are described, which are only used to explain the present invention. In fact, the support rod composed of multiple sections of long rods and multiple sensor fixtures can be adopted according to requirements. The above examples are not limitations to the present invention. Additionally, it should be noted that for the sake of description, only the parts related to the present invention rather than all the structures are shown in the drawings.

[0029] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] In the description of this embodiment, the orientation or positional relationships such as "upper" and "lower" are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0031] As Figures 1-3 shown, this embodiment provides a multi-purpose support tooling 100 for field testing, including support feet 1, support rods 2 and sensor clamps 3. The support feet 1 are inserted into the ground through three L-shaped forks 11. The support rods 2 are composed of multiple sections of tubular long rods. The end close to the ground is threadedly connected to the support feet 1 and tightened by a fastening nut 12. Taking two sections of long rods as an example, it includes a lower vertical rod 21 and an upper vertical rod 22. The upper vertical rod 22 is slidably connected to the lower vertical rod 21. A first welding nut 211 and a first tightening screw 212 are arranged on the lower vertical rod 21 to lock the upper vertical rod 22 at different height positions so as to maintain the upper vertical rod 22 within the test height required by the sensor. The sensor clamp 3 is slidably connected to the upper vertical rod 22. A second welding nut 31 and a second tightening screw 32 are arranged on the sensor clamp 3 to lock the sensor clamp 3 at different height positions to meet the test height required by the sensor.

[0032] In this embodiment, the support feet 1, support rods 2 and sensor clamps 3 are all made of stainless steel, ensuring that the multi-purpose support tooling 100 for field testing can provide the support strength required for field test experiments. The support feet 1 are of a solid tube L-shaped structure, with one end being conical, which reduces the difficulty of fixation when inserted into the ground such as in gobi, desert, soil, etc. The support rods 2 are of a sleeve structure. The lower end of the upper vertical rod 22 is movably arranged inside the lower vertical rod 21, enabling the upper vertical rod 22 to stably move inside the lower vertical rod 21. Further, the sleeve structure of the lower vertical rod 21 includes a tube bottom and a first tube. The tube bottom is of a circular structure, with 3 threaded holes evenly distributed in the circumferential direction, which are threadedly connected to the L-shaped forks 11 of the support feet 1 and tightened by a fastening nut 12. The tube bottom is fixed to the bottom of the first tube. In this embodiment, the tube bottom is welded to the first tube, with a firm connection. The upper vertical rod 22 is a second tube. According to the width of the sensor data transmission cable, a groove is opened on the side of the second tube so that the sensor data transmission cable can pass through the tube groove and enter the inside of the second tube. The upper vertical rod 22 and the lower vertical rod 21 are fixedly connected through the first welding nut 211 and the first tightening screw 212. The sensor clamp 3 is of a tubular structure. The inner diameter of the sensor clamp 3 is slightly larger than the outer diameter of the upper vertical rod 22, enabling the sensor clamp 3 to stably move on the upper vertical rod 22. According to the specific sensor 300 required for the test, the corresponding connection method is selected. According to the height required for the layout of the sensor 300, the central sleeve is installed at different positions on the upper vertical rod 22. The sensor clamp 3 and the upper vertical rod 22 are fixedly connected through the second welding nut 31 and the second tightening screw 32.

[0033] This embodiment is not limited to the installation and use of sensors required for field tests, and can also be used for the installation and use of other to-be-installed parts 300 with high requirements. This multi-purpose support tooling 100 for field tests is mostly made of tubular steel. Only the installation relationship is required, and the dimensions of the tubular steel are not strictly required. Therefore, adapted profiles can be used for processing. This multi-purpose support tooling 100 for field tests is modularly designed, can be operated by a single person, and is convenient for use, disassembly, packaging and transportation, thus improving the convenience of use.

[0034] This embodiment also provides a method for using the multi-purpose support tooling for field tests. Using the above-mentioned multi-purpose support tooling 100 for field tests, the method for using it includes the following steps:

[0035] Take the L-shaped fork 11 in one support foot 1, screw on the fastening nut 12 at the outer-threaded end, screw the fork into the threaded hole of the lower vertical rod 21, and screw it in more than 3 turns. When the axial direction of the tapered end of the fork is opposite to the axial direction of the lower vertical rod 21, unscrew the fastening nut 12 in the reverse direction when screwing it in until it contacts and presses tightly against the lower vertical rod 21. Connect the other two L-shaped forks to the lower vertical rod 21 in the same way to achieve the connection between the support foot 1 and the lower vertical rod 21;

[0036] Insert the upper vertical rod 22 into the lower vertical rod 21 from the other end of the support foot 1. According to the test height required by the sensor 300, adjust the depth of the upper vertical rod 22 inserted into the lower vertical rod 21, and screw the first tightening screw 212 into the first welding nut 211 at an appropriate position to achieve the connection between the upper vertical rod 22 and the lower vertical rod 21;

[0037] Install the sensor 300 required for field tests on the sensor tooling 33, and put the sensor fixture 3 on the upper vertical rod 22 from the other end of the support foot 1. According to the test height required by the sensor 300, adjust the position of the sensor fixture 3 on the upper vertical rod 22, and screw the second tightening screw 32 into the second welding nut 31 at an appropriate position to achieve the connection between the sensor fixture 3 and the upper vertical rod 22;

[0038] Pass the data transmission cable of the sensor 300 through the pipe groove on the side of the upper vertical rod 22 and place it inside the second tube. Wind it around the circumference of the second tube with wire or the like to prevent the data transmission cable from slipping out of the pipe groove during use.

[0039] Insert the multi-purpose support tooling 100 for field tests into the ground at the position required for field tests. To resist the harsh field test environment, heavy objects such as sandbags can be pressed on the support foot 1 to improve the support strength of this tooling.
