[0002] The spiral anchor, also known as the spiral pile, is an anchoring structure that penetrates deep into the soil. It consists of one or more spiral plates welded at equal intervals on a long screw or steel rod, and a certain torque is applied to the top of the screw to screw it into the soil. The spiral anchor has good bidirectional compression and tension resistance, and can be used as the pile foundation of a building to make the building more stable and safe.

[0003] Different soil types require different screw anchor specifications because the soil type, density, water content and other characteristics will directly affect the bearing capacity and stability of the screw anchor.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0029] The following will refer to the attached Figures 1 to 4 The utility model is described in detail in conjunction with the embodiments.

[0030] In general, the utility model relates to a screw anchor torque surveying machine, which is used to test the soil quality in the construction area and obtain data. It includes a vertically arranged support rod 1, a sliding groove 101 opened along the length direction of the support rod 1, a sliding block 2 slidably connected in the sliding groove 101, a fixed cylinder 3 fixedly arranged on the bottom surface of the sliding block 2, a first motor 4 fixedly arranged in the fixed cylinder 3, a vertical rod 6 fixedly connected to the output shaft of the first motor 4, a plurality of spiral pieces 602 spaced apart on the outer circumference of the vertical rod 6, and a tip 604 fixedly arranged at the bottom end of the vertical rod 6.

[0031] like Figure 2 and Figure 3 As shown, a torque sensor 5 is fixedly provided between the vertical rod 6 and the output shaft of the first motor 4 , and a lifting component for driving the sliding block 2 to move up and down in the sliding groove 101 is provided on the support rod 1 .

[0032] In this embodiment, the rotation of the first motor 4 drives the vertical rod 6 to rotate and penetrate the ground. The spiral pieces 602 are spiral and arranged at intervals, which improves the ability to penetrate the ground deeply. The tip 604 is conical and pointed downward, which further increases the penetration ability. In addition, the lifting group can drive the sliding block 2 to drive the vertical rod 6 to operate downward.

[0033] In a specific implementation, the fixed cylinder 3 plays a role in fixing the first motor 4, and the first motor 4 is fixed to the inner wall of the fixed cylinder 3 through the fixing portion 302, which can be a snap connection, a screw connection, etc. In addition, since the torque sensor 5 is in the fixed cylinder 3, the fixed cylinder 3 also plays a role in shielding and protecting the torque sensor 5, reducing the interference of external factors. Preferably, a detachable cover 301 is provided at the bottom of the fixed cylinder 3 to facilitate the installation of the first motor 4, and the vertical rod 6 passes through the cover 301 to the inside of the fixed cylinder 3, and is connected to the output shaft of the first motor 4 through the torque sensor 5.

[0034] It should be noted that the torque sensor 5 is used to test the torque when the vertical rod 6 breaks the soil surface. The torque applied by rotating the spiral anchor rod is the force required to enable the spiral anchor to be smoothly screwed into the soil and reach a predetermined depth. The specifications of the spiral anchor are customized based on the torque data.

[0035] It should be understood that the torque sensor 5, also known as a torque sensor, a moment sensor, a torque sensor or a torque meter, is a sensor for detecting the torsional moment on various rotating or non-rotating mechanical parts. It can accurately convert the physical changes of these torques into electrical signals, thereby realizing the measurement of torque. Generally, the torque sensor 5 should be installed close to the object to be measured (i.e., the vertical rod 6) or the main transmission shaft to reduce the installation error and improve the measurement accuracy.

[0036] In the present invention, the torque sensor 5 used is FUTEK MTA505. Of course, comprehensive consideration can also be made based on specific application scenarios, measurement range, accuracy requirements and other factors to ensure that the most suitable model is selected, and no further limitation is made here.

[0038] In specific implementation, the second motor 802 is started, and its forward and reverse rotation drives the screw rod 8 to drive the sliding block 2 to slide up and down, and then the vertical rod 6 is screwed down for testing. In the event of an unexpected power failure, the screw rod 8 can also play a limiting role to prevent the vertical rod 6 from falling.

[0039] In order to facilitate the stability of the device during testing, based on the setting of the above lifting components, such as Figure 2 As shown, a counterweight block 201 is provided at one end of the sliding block 2 away from the vertical rod 6 to prevent the sliding block 2 from being stuck when the screw rod 8 is driven to lift due to the weight imbalance of the sliding block 2. A limiter 801 is fixed at the top of the screw rod 8 to limit the sliding block 2 and prevent it from sliding out of the screw rod 8. In addition, as a preferred structure, a base 102 is fixed at the bottom end of the support rod 1, and the support rod 1 can better support the ground through the base 102, thereby increasing stability.

[0040] As the preferred structure of this embodiment, Figure 2 As shown, in order to meet the needs of different test schemes and screw anchor customization, in this embodiment, the spiral piece 602 is fixedly arranged on the fixing sleeve 601, and the fixing sleeve 601 is mounted on the vertical rod 6. By mounting multiple fixing sleeves 601, the number of spiral pieces 602 can be increased or decreased or the spacing between them can be adjusted. In specific implementation, the fixing sleeve 601 is fixedly connected to the vertical rod 6 through a nut. As another preferred structure, as Figure 4 As shown, in order to facilitate the disassembly and installation of the vertical rod 6 and the installation of the fixing sleeve 601, in this embodiment, the vertical rod 6 is composed of a plurality of short rods 603 connected end to end, and the short rods 603 are connected by a connecting sleeve 7. When connecting, the top end of the vertical rod 6 and the bottom end of another vertical rod 6 are respectively inserted into the two ends of the connection, and then fixed by screws.

[0041] As another embodiment of the utility model, the radius of the vertical rod 6 is 5 cm, the radius of the spiral piece 602 is 5 cm, and the pitch is 100-200 mm. Based on this structure, a database of spiral anchors of different specifications corresponding to different torques can be established, and the specifications of the spiral anchors can be adjusted based on this size.

[0042] In addition, in order to facilitate the control of the staff, in this embodiment, Figure 1As shown, the first motor 4 and the torque sensor 5 are connected to the control panel 9. In specific implementation, the control panel 9 can obtain data feedback of the torque sensor 5 and control the opening and closing of the first motor 4.

[0043] like Figure 1 As shown, as another embodiment, the integrated surveying machine can be installed on a vehicle 10, so that the operator can drive the vehicle 10 to change different work sites.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
