Description

Technical Field

[0001] This application relates to the field of geotechnical engineering investigation technology, specifically a support device for deep foundation pit geotechnical engineering investigation. Background Technology

[0002] Deep foundation pit engineering is an important part of construction engineering, involving multiple stages such as geotechnical engineering investigation, support structure design, foundation pit excavation and support construction. Among them, the support device in the geotechnical engineering investigation of deep foundation pits is the key equipment to ensure the safety and smooth progress of the investigation work.

[0003] An existing patent (publication number: CN219775234U) discloses a support device for geotechnical engineering investigation. It includes a base plate, a fixed frame fixedly connected to the top of the base plate, a transmission mechanism movably connected to the top of the fixed frame, and a lifting plate movably connected to the top of the fixed frame. The transmission mechanism includes a motor, and the output end of the motor extends through the interior of the fixed frame and is fixedly connected to a positive and negative threaded rod.

[0004] The above solution allows for height adjustment, ensuring normal use by the user without requiring the user to select a support device of appropriate height. However, some survey tasks have high precision requirements for the support device, necessitating that the support device be precisely adjusted to the required angle to ensure the accuracy of the survey data. The above solution can only adjust the height of the support plate but cannot adjust the angle, resulting in low practicality of the device and certain limitations in its use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a support device for deep foundation pit geotechnical engineering investigation, which has advantages such as height and angle adjustment, and solves the problem of the inability to adjust the angle of the support device.

[0006] To achieve the above objectives, this application provides the following technical solution: a support device for deep foundation pit geotechnical engineering investigation, comprising a base plate, a hinge seat fixedly connected to the upper surface of the base plate, a hinge block hinged to the outer surface of the hinge seat, an adjustable support structure provided on the outer surface of the hinge block, the adjustable support structure comprising a protective box fixedly connected to the outer surface of the hinge block, two symmetrical sliders fixedly connected to the outer surface of the protective box, two symmetrical semicircular plates fixedly connected to the upper surface of the base plate, each of the two semicircular plates having an arc-shaped groove on its outer surface, an arc-shaped array of insertion holes on the outer surface of the arc-shaped groove, and a limiting mechanism provided on the outer surface of each of the two sliders, the limiting mechanism comprising a fixing plate fixedly connected to the outer surface of the slider, a limiting rod inserted into the inner wall of the fixing plate, the outer surface of the limiting rod being inserted into the inner wall of the insertion hole.

[0007] The above scheme, through the function of setting hinge seats and hinge blocks, can drive the overall adjustable support structure to adjust the angle. This allows for precise adjustment to the required angle according to actual needs, thereby adapting to different exploration requirements and working environments, thus improving the flexibility and stability of exploration work. Subsequently, through the cooperation of setting limit rods and insertion holes, when the angle is adjusted to the specified position, the limit rods are inserted into the insertion holes to limit the adjusted angle, ensuring that the adjusted device remains stable at the required angle position and will not shift due to external forces, thus ensuring the stability and safety of the support.

[0008] Furthermore, the outer surface of the slider is slidably connected to the inner wall of the arc-shaped groove.

[0009] The above scheme, by setting the arc groove, can provide a clear sliding path for the slider, thereby making the angle adjustment process of the adjustable support structure more precise and controllable.

[0010] Furthermore, the external dimensions of the limiting rod are adapted to the inner wall dimensions of the insertion hole.

[0011] The above solution uses a limiting rod to ensure that its size matches the socket. This allows the limiting rod to be inserted smoothly into the socket, preventing shaking or loosening caused by size mismatch.

[0012] Furthermore, a tension plate is fixedly connected to one end of the limiting rod away from the inner wall of the insertion hole, and a tension spring is fixedly connected to one side of the tension plate near the limiting rod. The end of the tension spring away from the outer surface of the tension plate is fixedly connected to the outer surface of the fixing plate.

[0013] The above solution, by setting the tension spring, can drive the pulling plate to move so that the limiting rod can be stably inserted into the inner wall of the insertion hole. The elastic force of the tension spring can ensure that the limiting rod is always kept in the insertion hole, preventing loosening or displacement caused by vibration or external force.

[0014] Furthermore, a servo motor is fixedly installed inside the protective box, and a lead screw is fixedly connected to the output end of the servo motor. The outer surface of the lead screw is rotatably connected to the inner wall of the protective box.

[0015] The above solution, by setting a fixing plate, can protect the limit rod from interference and damage from the external environment, thereby extending the service life of the motor and reducing the failure rate.

[0016] Furthermore, a sleeve is threadedly connected to the outer surface of the lead screw, and a support plate is fixedly connected to the upper surface of the sleeve.

[0017] The above scheme, by setting the functions of the lead screw and sleeve, when the lead screw rotates, it can drive the sleeve to move up and down and drive the support plate to adjust its height. This allows the device to adapt to working environments at different heights and provides stable support for surveying.

[0018] Furthermore, the bottom surface of the support plate is fixedly connected to four rectangular array telescopic rods, and the bottom ends of the four telescopic rods are fixedly connected to the upper surface of the protective box.

[0019] The above scheme, by setting up a telescopic rod, can guide the lifting and lowering movement of the support plate and sleeve, thereby ensuring the stable and directional movement of the support plate.

[0020] Furthermore, multiple conical blocks are fixedly connected to the bottom surface of the base plate.

[0021] The above solution utilizes a base plate. When the base plate is installed on the ground, the conical block at its bottom is driven into the ground, providing stable support for the base plate. This prevents it from loosening due to vibration or external forces during use, thus maintaining the stability and safety of the device.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This type of support device for deep foundation pit geotechnical engineering investigation, through the setting of hinge seats and hinge blocks, can drive the overall adjustable support structure to adjust the angle. This allows for precise adjustment to the required angle according to actual needs, thereby adapting to different investigation requirements and working environments, thus improving the flexibility and stability of the investigation work. Subsequently, through the cooperation of setting limit rods and insertion holes, when the angle is adjusted to the designated position, the limit rods are inserted into the insertion holes to limit the adjusted angle, ensuring that the adjusted device remains stable at the required angle position and will not shift due to external forces, thus ensuring the stability and safety of the support.

A hinge seat 2 is fixedly connected to the upper surface of the base plate 1. A hinge block 3 is hinged to the outer surface of the hinge seat 2. An adjustable support structure 4 is provided on the outer surface of the hinge block 3. By setting the hinge seat 2 and the hinge block 3, the adjustable support structure 4 can be adjusted at an angle. This allows for precise adjustment to the required angle according to actual needs, thus adapting to different investigation requirements and working environments, thereby improving the flexibility and stability of the investigation work. The adjustable support structure 4 includes a protective box 401 fixedly connected to the outer surface of the hinge block 3. Two symmetrical sliders 5 are fixedly connected to the outer surface of the protective box 401. Two adjustable sliders 5 are fixedly connected to the upper surface of the base plate 1. The two semicircular plates 6 are symmetrical. The outer surfaces of the two semicircular plates 6 are provided with arc-shaped grooves 7. The outer surfaces of the arc-shaped grooves 7 are provided with arc-shaped array of insertion holes 8. The outer surfaces of the two sliders 5 are provided with limiting mechanisms 9. The limiting mechanism 9 includes a fixing plate 901 fixedly connected to the outer surface of the slider 5. The inner wall of the fixing plate 901 is inserted with a limiting rod 902. The outer surface of the limiting rod 902 is inserted into the inner wall of the insertion hole 8. By setting the limiting rod 902 and the insertion hole 8 in cooperation, when the angle is adjusted to the specified position, the limiting rod 902 is inserted into the inside of the insertion hole 8 to limit the adjusted angle, ensuring that the adjusted device remains stable at the required angle position and will not shift due to external force, thus ensuring the stability and safety of the support.

[0032] Please see Figure 1 and Figure 2The outer surface of the slider 5 is slidably connected to the inner wall of the arc groove 7. By setting the arc groove 7, a clear sliding path can be provided for the slider 5, making the angle adjustment process of the adjustable support structure 4 more precise and controllable. Multiple conical blocks are fixedly connected to the bottom surface of the base plate 1. By setting the base plate 1, when the base plate 1 is installed on the ground, the conical blocks at its bottom are driven into the ground, thereby providing stable support for the base plate 1 and preventing it from loosening due to vibration or external force during use, thus maintaining the stability and safety of the device.

[0033] Please see Figure 1 and Figure 4 The external dimensions of the limiting rod 902 are adapted to the inner wall dimensions of the socket 8. By setting the limiting rod 902, the size of the limiting rod 902 is adapted to the socket 8, so that when the limiting rod 902 is inserted into the socket 8, it can be smoothly inserted into the socket 8, and it also avoids shaking or loosening caused by size mismatch. The end of the limiting rod 902 away from the inner wall of the socket 8 is fixedly connected to the pull plate 903. The side of the pull plate 903 near the limiting rod 902 is fixedly connected to the tension spring 904. The end of the tension spring 904 away from the outer surface of the pull plate 903 is fixedly connected to the outer surface of the fixing plate 901. By setting the tension spring 904, the pull plate 903 can be moved to make the limiting rod 902 stably inserted into the inner wall of the socket 8. Furthermore, the elastic force of the tension spring 904 can ensure that the limiting rod 902 always stays in the socket 8, preventing loosening or displacement caused by vibration or external force.

[0034] Please see Figure 1 , Figure 2 and Figure 3 A servo motor 402 is fixedly installed inside the protective box 401. A lead screw 403 is fixedly connected to the output end of the servo motor 402. The outer surface of the lead screw 403 is rotatably connected to the inner wall of the protective box 401. The fixed plate 901 protects the limit rod 902 from external environmental interference and damage, thereby extending the motor's service life and reducing the failure rate. A sleeve 404 is threaded onto the outer surface of the lead screw 403. A support plate 405 is fixedly connected to the upper surface of the sleeve 404. By setting the lead screw 403 and sleeve 405... The function of screw 404 is to drive sleeve 404 to move up and down when screw 403 rotates, and to drive support plate 405 to adjust its height. This allows the device to adapt to working environments at different heights and provides stable support for surveying. Four rectangular array telescopic rods 406 are fixedly connected to the bottom surface of support plate 405. The bottom ends of the four telescopic rods 406 are fixedly connected to the upper surface of protective box 401. By setting the telescopic rods 406, the lifting and lowering movement of support plate 405 and sleeve 404 can be guided, thereby ensuring the stable and directional movement of support plate 405.

[0035] This embodiment of a support device for deep foundation pit geotechnical engineering exploration, through the function of the hinge seat 2 and hinge block 3, can drive the adjustable support structure 4 to adjust the angle as a whole. This allows for precise adjustment to the required angle according to actual needs, thereby adapting to different exploration requirements and working environments, thus improving the flexibility and stability of the exploration work. Subsequently, through the cooperation of the limiting rod 902 and the insertion hole 8, when the angle is adjusted to the specified position, the limiting rod 902 is inserted into the insertion hole 8 to limit the adjusted angle, ensuring that the adjusted device remains stable at the required angle position and will not shift due to external forces, thus ensuring the stability and safety of the support.

[0036] It should be noted that the hinge seat 2, hinge block 3, slider 5, and limit rod 902 are all made of high-strength alloy material, which can provide stable support when the adjustable support structure 4 is adjusted in angle, and avoid breakage during the support process.

[0037] The working principle of the above embodiment is as follows: When using this device, the base plate 1 is first placed at a designated location. Then, when adjusting the angle as needed, the pulling plate 903 is pulled to disengage the limiting rod 902 from the inner wall of the insertion hole 8. Subsequently, under the action of the hinge seat 2 and the hinge block 3, the adjustable support structure 4 can be adjusted as a whole. At the same time, under the action of the arc groove 7, a clear sliding path is provided for the slider 5, making the angle adjustment process of the adjustable support structure 4 more precise and controllable. Thus, it can be precisely adjusted to the required angle according to actual needs. After the angle adjustment is completed, the tension on the tension plate 903 is released. At this time, the tension force generated by the deformation of the tension spring 904 can drive the limiting rod 902 to be stably inserted into the insertion hole 8, thereby limiting the slider 5 and limiting the angle of the adjustable support structure 4. Then, the servo motor 402 is started to drive the lead screw 403 to rotate. With the limiting guide of the telescopic rod 406, the sleeve 404 is moved up and down and the support plate 405 is adjusted in height. This allows the device to adapt to working environments at different heights and provides stable support for surveying.
