Description

Technical Field

[0001] This invention belongs to the field of surveying support technology, and specifically relates to a surveying support for soft ground. Background Technology

[0002] Surveying refers to the process of measuring, collecting, and mapping natural geographical elements or surface facilities. With the development of technology, people usually use surveying instruments for surveying, including leveling instruments, total stations, and GPS. Since surveying instruments are often used in areas with complex terrain, fixed supports are needed to fix and support them.

[0003] Chinese patent CN219623715U discloses a surveying support for soft ground, comprising a base plate, an upper mounting plate, and a rotating structure on the lower side of the mounting plate. Three rotating sleeves are evenly fixedly connected to the lower end face of the base plate, and support sleeves are rotatably connected within each of the three rotating sleeves. Support legs are connected to the support sleeves via locking bolts. Connecting frames are fixedly connected to the outer walls of the support legs, and rotating rods are rotatably connected within the connecting frames. The rotating rods are connected to the connecting frames via bolt assemblies, and a foot is fixedly connected to the bottom of the rotating rod. The rotating rod also has a ground-insertion structure. This design, through the connecting frames, rotating rods, bolt assemblies, foot, and ground-insertion structure, facilitates easy insertion into soft ground and increases the contact area, preventing sinking and solving the problem in existing technologies where surveying supports easily sink on soft ground, leading to a decrease in surveying accuracy.

[0004] In actual use, although the three sets of support sleeves, support legs, bolt assemblies, connecting frames, rotating rods and outriggers can provide support, fixation and adjustment, when the road surface has a certain slope, the direction of gravity of the surveying instrument is not perpendicular to the road surface. This will cause the pressure on the three sets of support rods to be inconsistent. Although the ground insertion structure can increase the anchorage of the support rods, the support rod with the greatest pressure may still slide on the soft soil surface due to excessive pressure, thus causing the device to be unable to provide stable support on the soft soil surface. Summary of the Invention

[0005] The present invention aims to provide a surveying support for soft ground to solve the problem of unstable support of existing supports when used on soft soil surfaces.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a support frame for soft ground mapping, comprising...

[0007] The mounting plate has a connecting pipe fixed to its bottom. The bottom of the connecting pipe is rotatably connected to a limiting pipe. The side wall of the connecting pipe has a pushing groove that extends to the bottom of the limiting pipe.

[0008] The load-bearing rod assembly includes a ground cone rod, a pressure plate, and a push bar. The pressure plate is threadedly fitted to the ground cone rod, and the push bar is fixed to the circumferential side wall at the top of the ground cone rod. The top of the ground cone rod passes through the limiting tube and slides inside the connecting tube, and the push bar slides in the push groove.

[0009] The support rod assembly includes multiple support units spaced apart at the bottom of the mounting plate.

[0010] The principle and effects of this technical solution:

[0011] 1. By installing the load-bearing rod assembly and the support rod assembly at the bottom of the mounting plate, the surveying instrument can be mounted on the mounting plate. The weight of the entire device can be distributed by the load-bearing rod assembly, so that the support rod assembly only needs to provide partial anti-tilting support, thus making the device more stable when used on soft soil.

[0012] 2. Because the ground cone rod and connecting pipe in the load-bearing rod assembly are slidably inserted, the entire load-bearing rod assembly can be disassembled relative to the connecting pipe. That is, when fixed on the soft soil surface, the load-bearing rod assembly can be anchored first. After the load-bearing rod assembly is anchored, the connecting pipe, i.e., the mounting plate, is then installed and fixed. The ground cone rod penetrates deep into the soft soil layer, making the soft soil layer more compact. The bearing plate presses against the soft soil surface, thereby increasing the contact area between the anchor rod and the soft soil surface and further compacting the soft soil surface below. Thus, when the connecting pipe is fitted onto the ground cone rod, most of the weight can be borne by the ground cone rod, which in turn distributes the weight to the surrounding compacted soft soil surface. Therefore, when the support rod assembly is in place, even if the road surface is inclined, the support rod assembly is not easy to slip. In other words, the device is more stable when fixed.

[0013] 3. Through the cooperation of the push bar and the push groove, and the rotating installation of the limiting tube and the connecting tube, when the push bar is deeply inserted into the connecting tube and completely separated from the limiting tube, the pushing groove of the limiting tube and the push bar can be misaligned by rotating the limiting tube, thereby realizing the limiting tube's limitation on the push bar. This ensures that the mounting plate is stably installed on the ground cone rod, and the limiting tube can be rotated to cancel the limiting tube's limitation on the limiting bar, making the device more convenient to install and remove, and more stable when fixed.

[0014] 4. Because the bearing plate and the ground cone rod are threaded together, the position of the bearing plate relative to the ground cone rod can be rotated and controlled according to the soil conditions of the soft soil surface and the actual required height. That is, the depth of the ground cone rod penetrating the soil layer and the height of the ground cone rod above the ground can be controlled, so that the device can adapt to more usage needs.

[0015] The present invention is further configured such that: the support unit includes a support leg, a support sleeve and a connecting rod, the support sleeve is hinged to the bottom of the mounting plate, the support leg is threaded into the bottom of the support sleeve, one end of the connecting rod is hinged to the tube body of the support sleeve, and the other end of the connecting rod is hinged to a control ring, the control ring is slidably fitted onto the connecting tube, and a control component is installed on the control ring, the control component being used to control the position of the control ring.

[0016] The principle and effect of this technical solution are as follows: Because the support sleeve is hinged to the mounting plate, and the two ends of the connecting rod are respectively hinged to the support sleeve and the control ring, and the control ring slides on the connecting pipe, the support sleeve, the connecting rod, and the control ring form a crank-slider mechanism. By controlling the position of the control ring, the position of the support sleeve can be changed, so that the user does not need to adjust the position of each support unit individually. Furthermore, the position of the control ring is controlled by the control component, making the use of the control ring more stable and convenient. The support legs are threaded into the bottom of the support sleeve, so that the length of each support unit can be adjusted according to the actual road conditions, so that the support legs of each support unit can fully contact the road surface, thereby playing a stable anti-tilt function.

[0017] The invention is further configured such that: the control component includes a slider, the slider is fixed to the inner side of the control ring, and the slider slides in the push groove, the bottom of the slider abuts against the top of the push bar, and the top of the slider abuts against the top of the push groove.

[0018] The principle and effect of this technical solution: By setting the slider, when the connecting tube is fitted onto the ground cone rod, the push bar can abut against the slider, thereby driving the support rod assembly to unfold. This eliminates the need for manual control of the position of the support rod assembly. Furthermore, by rotating the limit tube to misalign the push groove with the push bar, the push bar can be prevented from sliding out of the push groove. Since the top and bottom of the slider are restricted, stable support can be provided for the control ring, i.e., the support rod assembly. The method of controlling the connection between the connecting tube and the ground cone rod by rotating the limit tube is simple and convenient to operate.

[0019] The invention is further configured such that a reset spring is fitted outside the connecting pipe, and the reset spring is located between the mounting plate and the control ring.

[0020] The principle and effect of this technical solution: The reset spring allows the device to automatically drive the limit tube and the push bar to cooperate after use by rotating the push groove of the limit tube to align with the push bar. This avoids the push bar from easily misaligning with the push groove of the limit tube when lifting the mounting plate. Furthermore, during transportation, the reset spring tends to automatically drive the control ring away from the mounting plate, thus allowing the support rod assembly to automatically maintain its retracted state, making it easier to transport and carry.

[0021] The invention is further configured such that: the control component also includes a control cylinder, a control plate, a control rod, and a control spring; the control cylinder is fixed to the outer wall of the control ring; a limiting hole is provided on the side wall of the connecting pipe; the control rod is slidably inserted into the control cylinder, with one end of the control rod extending into the limiting hole and the other end extending out of the control cylinder; the control plate is fixed to the control rod and slides inside the control cylinder; and the control spring is installed inside the control cylinder and located on the side of the control plate away from the connecting pipe.

[0022] The principle and effect of this technical solution: By controlling the elastic force of the spring, the control plate tends to move spontaneously closer to the connecting pipe, thus causing the control rod to tend to move spontaneously toward the connecting pipe. When the control rod aligns with the limiting hole, the spring's drive can move the control rod into the limiting hole, thereby limiting the position of the control ring. Even if the control ring cannot move up or down, it limits the position of the support rod assembly hinged to it, preventing the support rod assembly from changing position during use. Through the additional restriction of the control rod, when the ground cone rod and push bar cannot be used (i.e., on a hard surface, the ground cone rod cannot be inserted into the bottom layer, thus preventing the limiting pipe from limiting the push bar), the device can still limit the position of the control ring through the control rod, allowing the device to be used on hard surfaces as well. That is, by pressing down the mounting plate, the support rod assembly comes into contact with the ground, and the pressure drives the support rod assembly away from the connecting pipe, causing the control ring to move upward relative to the mounting plate, thus aligning the control rod with the limiting hole, and then inserting the control rod into the limiting hole to limit the control ring.

[0023] The invention is further configured such that: the bearing plate is inverted conical in shape, and multiple inclined insertion holes are spaced apart along the circumference of the bearing plate; anchor screws are slidably inserted into the insertion holes; a lower pressure block is threaded onto the ground cone rod, and the bottom of the lower pressure block abuts against the nut of the anchor screw.

[0024] The principle and effect of this technical solution: When the inverted cone-shaped bearing plate is pressed onto the soft soil surface, it not only compacts the soil layer directly below but also tightens the surrounding soil. This makes the ground cone rod more firmly anchored in the soft soil layer, resulting in a more compact soft soil surface at the installation point. This makes it less likely for the bearing plate and ground cone rod to tip over or slide after installation. By setting the inclined anchoring screws, after the bearing plate is pressed into the ground, the anchoring screws can be controlled to penetrate the soft soil surface, further enhancing the anchoring effect. This increases the compactness of the surrounding soft soil surface, making the fixation more stable and easier to install and disassemble. By rotating the lower pressure block, the lower pressure block moves downward, driving the anchoring screws to penetrate the soil layer. This method does not easily damage the existing soft soil surface, meaning it does not compromise the supporting effect of the soft soil layer on the ground cone rod and bearing plate.

[0025] The invention is further configured such that: a fixing plate is rotatably connected to the top of the mounting plate, a circular groove is provided on the mounting plate, and a control bolt is threaded into the fixing plate, with the end of the control bolt extending into the circular groove.

[0026] The principle and effect of this technical solution: By setting up a rotating connection of the fixed plate, the surveying instrument can be installed on the fixed plate and the surveying angle can be changed by rotating the fixed plate, which facilitates the angle adjustment of the surveying instrument. By setting up control bolts, the position of the fixed plate can be restricted by tightening the control bolts against the circular sliding groove, thereby keeping the fixed plate stable and making the device more stable during use.

[0038] Example:

[0039] As attached Figure 1-9 As shown, this invention discloses a support frame for soft ground surveying, comprising a mounting plate 101, a load-bearing rod assembly, and a support rod assembly. A fixing plate 102 is rotatably connected to the top of the mounting plate 101. A circular groove 103 is formed on the mounting plate 101. A control bolt 104 is threaded into the fixing plate 102, with the end of the control bolt 104 extending into the circular groove 103. A fixing device for connecting to surveying instruments is installed on the fixing plate 102. This fixing device can be a threaded head, a hinged joint, etc., which are common fixing and installation structures and do not require further description. A connecting pipe 201 is fixed to the bottom of the mounting plate 101. A limiting pipe 301 is rotatably connected to the bottom of the connecting pipe 201. Two symmetrical pushing grooves 202 are formed on the side wall of the connecting pipe 201, and both pushing grooves 202 extend to the bottom of the limiting pipe 301.

[0040] The load-bearing rod assembly includes a ground cone rod 401, a pressure plate 402, and a pusher bar 403. The pressure plate 402 is threadedly fitted to the ground cone rod 401. The pusher bar 403 is fixed to the circumferential side wall of the top of the ground cone rod 401. The top of the ground cone rod 401 passes through the limiting tube 301 and slides in the connecting tube 201. The pusher bar 403 is slidably fitted in the pusher groove 202. The pressure plate 402 is inverted conical in shape. The pressure plate 402 is provided with four inclined insertion holes 404 spaced apart circumferentially. Anchor screws 405 are slidably inserted into the insertion holes 404. A lower pressure block 406 is threadedly fitted on the ground cone rod 401. The bottom of the lower pressure block 406 abuts against the nut of the anchor screw 405.

[0041] The support rod assembly includes at least three support units spaced apart at the bottom of the mounting plate 101.

[0042] The support unit includes a support leg 502, a support sleeve 501, and a connecting rod 503. The support sleeve 501 is hinged to the bottom of the mounting plate 101. The support leg 502 is threaded into the bottom of the support sleeve 501. One end of the connecting rod 503 is hinged to the body of the support sleeve 501, and the other end of the connecting rod 503 is hinged to a control ring 504. The control ring 504 is slidably fitted onto the connecting tube 201. A control component is installed on the control ring 504 to control the position of the control ring 504. A return spring 302 is also fitted outside the connecting tube 201. The return spring 302 is located between the mounting plate 101 and the control ring 504.

[0043] The control components include a slider 601, a control cylinder 602, a control plate 603, a control rod 604, and a control spring 605. The slider 601 is fixed to the inner side of the control ring 504 and slides within the push groove 202. The bottom of the slider 601 abuts against the top of the push bar 403, and the top of the slider 601 abuts against the top of the push groove 202. The control cylinder 602 is fixed to the outer wall of the control ring 504. A limiting hole 203 is provided on the side wall of the connecting tube 201. The control rod 604 is slidably inserted into the control cylinder 602, with one end of the control rod 604 extending into the limiting hole 203 and the other end extending outside the control cylinder 602. The control plate 603 is fixed to the control rod 604 and slides within the control cylinder 602. The control spring 605 is installed within the control cylinder 602 and is located on the side of the control plate 603 away from the connecting tube 201.

[0044] The specific implementation process is as follows:

[0045] When using this device on soft soil, firstly, the position of the bearing plate 402 is controlled according to the required height of the mounting plate 101 and the required penetration depth of the ground cone rod 401. This is achieved by rotating the bearing plate 402 relative to the ground cone rod 401. After adjustment, the ground cone rod 401 is inserted into the soft soil at the placement point. Stepping on the bearing plate 402 can further drive the ground cone rod 401 into the soil layer, simultaneously pressing the bearing plate 402 into the soft soil surface. After the upper surface of 2 is flush with the soft soil surface, insert the anchor screw 405 into the insertion hole 404, and then gently press the anchor screw 405 so that the end of the anchor screw 405 penetrates the soil layer. Then, by rotating the lower pressure block 406, the lower pressure block 406 drives the anchor screw 405 to penetrate. When the lower pressure block 406 can no longer drive the anchor screw 405 into the soil layer by rotation, the soft soil surface at the fixing point is compacted and the ground cone rod 401 is firmly fixed. At this time, the pushing groove 2 of the limiting tube 301 is opened. Align the push bar 403 of the ground cone rod 401 with the ground cone rod 401, and fit the limiting tube 301 and the connecting tube 201 onto the ground cone rod 401. Then, by pressing the fixing plate 102, the connecting tube 201 is driven to move downward, thereby causing the push bar 403 to push the slider 601 to drive the control ring 504 to move upward. This causes the control ring 504 to control the support rod assembly to unfold. When the fixing plate 102 can no longer move downward, that is, when the slider 601 abuts against the top of the push groove 202, the control rod 60 in the control component is activated. 4. Inserted into the limiting hole 203, it serves as the initial limit for the control ring 504. By rotating the pushing groove 202 of the limiting tube 301 to misalign with the pushing bar 403, it provides a second layer of restriction and support, thereby stabilizing the position of the control ring 504. At this time, the mounting plate 101 is placed in place. By adjusting each support leg 502, the support leg 502 is pressed against the soft soil surface, thus completing the installation and fixing of the device. At this time, only the surveying instrument needs to be installed on the fixing plate 102 for it to be used.

[0046] When used on hard surfaces, the load-bearing rod assembly is not required. Simply place the device at a fixed point and press the fixing plate 102 to move each support unit away from the connecting pipe 201. This allows the support sleeve 501 to move the control ring 504 away from the limiting pipe 301. Once the control rod 604 is inserted into the limiting hole 203, the position of the control ring 504 is restricted, which in turn restricts the position of each support sleeve 501 and support leg 502. By adjusting the length of the support leg 502, each support unit can be made to fully contact the ground, thus enabling the device to be used on hard surfaces and making it highly adaptable.
