Description

Technical Field

[0001] This utility model belongs to the technical field of surveying instrument support, specifically relating to a mobile support for a gully slope surveying instrument. Background Technology

[0002] Before gully erosion control, it is necessary to measure the slope morphology on both sides of the gully to determine the amount of earthwork to be excavated. Traditionally, slope morphology measurement is done manually using RTK (Real-Time Kinematic) measurement equipment. A measurement section of the gully is pre-selected, and a person holds the RTK device and makes multiple measurements on the slope of the section to obtain the slope morphology of the measured area. This manual measurement requires workers to constantly climb the slope to reach the measurement points, which is physically demanding and carries certain risks. The existing patent application number is: 202411964667. .3. The patent titled "A Multi-Angle Slope Mapping Device for Territorial Spatial Planning" discloses a slope mapping instrument. For erosion gullies with relatively clean bottom structures (erosion gullies without weeds or large amounts of snow accumulation), using a mapping instrument to measure slopes can greatly improve the efficiency of slope measurement. Compared with the traditional handheld RTK measurement method, this method is safer. However, the disadvantage is that the overall weight of the mapping instrument and support is relatively large compared with RTK measurement equipment, and the mobility is not high. It will be inconvenient when two people carry and move it. Therefore, developing a mobile support for an erosion gully slope mapping instrument to solve the above problems is very much in line with practical needs. Utility Model Content

[0003] In order to solve the problems of large weight and low mobility of existing surveying instruments for measuring erosion gully slopes, this utility model provides a mobile support for the erosion gully slope surveying instrument.

[0004] A mobile support for an erosion gully slope surveying instrument, the mobile support including a surveying instrument mounting plate, and multiple support rod assemblies for support are installed at the bottom edge of the surveying instrument mounting plate.

[0005] A foldable moving unit is installed at the bottom center of the surveying instrument mounting plate to move the surveying instrument mounting plate and support rod assembly. The foldable moving unit includes a vertical support rod installed at the bottom of the surveying instrument mounting plate, and a folding wheel assembly for movement is hinged to the bottom of the vertical support rod.

[0006] Furthermore, the bottom of the vertical strut is provided with a limiting plate for limiting the support rod assembly in the closed state, and the folding wheel assembly is hinged to the limiting plate;

[0007] Furthermore, the surveying instrument mounting plate is equipped with handles for supporting the mobile support frame;

[0008] Furthermore, the folding wheel assembly includes a folding arm hinged to a limiting plate, with an axle rotatably connected to the end of the folding arm, and a rotating wheel fitted at each end of the axle;

[0009] Furthermore, a steering seat for steering is rotatably connected to the end of the folding arm, and a wheel axle is rotatably connected to the steering seat;

[0010] Furthermore, a limiting structure is provided on the side wall at the bottom of the vertical strut to keep the folding wheel assembly stable in the folded state;

[0011] Furthermore, the limiting plate is provided with a limiting structure to keep the folding wheel assembly stable in the unfolded state;

[0012] Furthermore, the support rod assembly includes a mounting base installed at the bottom of the surveyor mounting plate. A hinge block for adjusting the working angle of the support rod assembly is hinged to the mounting base. A screw for adjusting the working length of the support rod assembly is fixed to the hinge block. A threaded sleeve for support is threaded onto the screw. A cone for insertion into the support surface is installed at the end of the threaded sleeve.

[0013] Furthermore, the end of the threaded sleeve is rotatably connected to a transition block, on which a cone for insertion into the support surface is mounted, and on which a folding support leg assembly for assisting the cone in providing support is mounted.

[0014] The beneficial effects of this application compared to the prior art are:

[0015] This application provides a mobile support for an erosion gully slope surveying instrument. Compared to traditional surveying instrument supports, it adds a folding wheel assembly. The folding wheel assembly has two working states: when the support is in the folded state, the folding wheel assembly is in the unfolded state, used to provide single-point support for the entire support. Figure 3 As shown, this design facilitates the movement of the entire support structure by staff. This design eliminates the need for two people to carry the slope surveying instrument and support structure, greatly reducing the labor intensity of the staff. When the support structure is in the unfolded state, the folding wheel assembly is folded and close to the vertical support rod, saving space for the device layout and facilitating the staff's surveying work. In this application, the folding wheel adopts a double wheel structure to increase the contact area with the bottom of the erosion gully, thereby improving the stability of the support structure when staff push it to move on gentle slopes.

[0016] This application provides a mobile support for an erosion gully slope mapping instrument. Considering that there may be uneven areas at the bottom of the erosion gully, relying solely on a traditional tripod support cannot guarantee the stability of the support. Therefore, this application improves the traditional tripod support by first optimizing the structure of each leg so that the working length of each leg can be adjusted independently to adapt to the height difference at the bottom of the erosion gully. Secondly, a folding leg assembly is set at the bottom of each leg to improve the support stability of a single leg. Attached Figure Description

[0041] Specific implementation method one: Combining Figures 1 to 11 This embodiment describes a mobile support for an erosion gully slope surveying instrument. The mobile support includes a surveying instrument mounting plate 1, and multiple support rod assemblies 2 for support are installed at the bottom edge of the surveying instrument mounting plate 1.

[0042] A foldable movable unit for moving the surveyor mounting plate 1 and the support rod assembly 2 is installed at the bottom center of the surveyor mounting plate 1.

[0043] The foldable mobile unit includes a vertical support rod 3 installed at the bottom of the surveyor mounting plate 1. The bottom of the vertical support rod 3 is provided with a limiting plate 4 for limiting the support rod assembly 2 in the closed state. The folding wheel assembly 5 is hinged to the limiting plate 4.

[0044] The support rod assembly 2 includes a mounting base 21 installed at the bottom of the surveyor mounting plate 1. A hinge block 22 for adjusting the working angle of the support rod assembly is hinged to the mounting base 21. A screw 23 for adjusting the working length of the support rod assembly is fixed to the hinge block 22. A threaded sleeve 24 for support is threaded to the screw 23. A cone 26 for inserting into the support surface is installed at the end of the threaded sleeve 24.

[0045] The folding wheel assembly 5 includes a folding arm 51 hinged to the limiting plate 4, and a wheel axle 53 rotatably connected to the end of the folding arm 5. A rotating wheel 54 is respectively fitted at both ends of the wheel axle 53.

[0046] The surveying instrument mounting plate 1 is equipped with a handle 6 for supporting the mobile support.

[0047] This embodiment provides a mobile support frame for an erosion gully slope surveying instrument. The support rod assembly 2 typically consists of three members, which provide stable support to the instrument body 8 located on top of the instrument mounting plate 1 via three legs. Vertical support rods 3 are coaxially aligned with the instrument mounting plate 1, and their extension length is slightly less than the initial length of the support rod assembly 2. Three equidistant circumferential grooves are machined on the outer surface of the limiting plate 4 at the end of the vertical support rods, with each groove corresponding to one support rod assembly 2. When the three support rod assemblies 2 are in the retracted state, each support rod assembly... 2 will be embedded into a corresponding mounting slot. Each mounting slot in the limiting plate 4 has a set of oppositely arranged plastic paddles at its opening. When the support rod assembly 2 is embedded into the support rod assembly 2, the two plastic paddles first bend inward and then reset after the support rod assembly 2 is fully embedded into the mounting slot, thereby blocking the support rod assembly 2 and ensuring that the support rod assembly 2 cannot escape from the mounting slot when not subjected to external force. When it is necessary to unfold the support rod assembly 2, the support rod assembly 2 is manually opened outward, and the two plastic paddles first bend outward and then reset after the support rod assembly 2 is fully moved out of the mounting slot.

[0048] The support rod assembly 2 has a length adjustment function, which is achieved by the screw 23 and the threaded sleeve 24. When the threaded sleeve 24 rotates forward on the screw 23, the threaded sleeve 24 moves downward along the length extension direction of the screw 23, thereby increasing the working length of the support rod assembly 2. When the threaded sleeve 24 rotates in the opposite direction on the screw 23, the threaded sleeve 24 moves upward along the length extension direction of the screw 23, thereby shortening the working length of the support rod assembly 2. Through the length adjustment function of the support rod assembly 2, the mobile support can better adapt to the complex environment of the bottom of the erosion trench, thereby improving the working stability of the mobile support. The cone 26 installed at the end of the threaded sleeve 24 is used to insert into the bottom of the erosion trench to ensure the stability of the support.

[0049] A set of hinge ears is provided at the connection between the limiting plate 4 and the folding wheel assembly 5. The folding arm 51 in the folding wheel assembly 5 is set in the hinge ear and hinged to the hinge ear by a pin. When the folding arm 51 is in a vertical state, the folding wheel assembly 5 does not work. When the folding arm 51 is in a horizontal state, the folding wheel assembly 5 works. The folding wheel assembly 5 includes two rotating wheels 54. The double wheel design helps to increase the contact area between the moving part and the bottom of the trench, and improves the accuracy of the equipment movement. In order to facilitate the movement of the support by the staff, a set of hinge ears is also provided on the surveying instrument mounting plate 1. The handle 6 can have two forms: one is a ring structure, which is fitted onto the outer circle of the surveying instrument mounting plate 1 and fixedly connected to the surveying instrument mounting plate 1 through a connecting rod; the other is a folding structure, in which the fixed part of the handle 6 is fixed to the outer circle of the surveying instrument mounting plate 1, and the pushing part of the handle 6 is hinged to the fixed part. When it is necessary to use the handle 6 to complete the pushing action, the pushing part is opened and put into operation. When it is not necessary to use the handle 6 to complete the pushing action, the pushing part is folded under the fixed part to reduce the arrangement space and avoid interference with the work when using the surveying instrument for measurement.

[0050] Specific Implementation Method Two: Combining Figures 1 to 10 and Figure 12 This embodiment differs from Specific Embodiment 1 in that the end of the threaded sleeve 24 is rotatably connected to a transition block 25, and a cone 26 for insertion into the support surface is mounted on the transition block 25. Other components and connections are the same as in Specific Embodiment 1.

[0051] In this embodiment, the purpose of setting the transition block 25 is to ensure that the cone 26 does not rotate when the working length of the support rod assembly 2 is extended by rotating the threaded sleeve 24. This ensures that the cone 26 can be directly inserted into the soil at the bottom of the trench along the working angle adjusted by the support rod assembly 2. If the cone 26 rotates synchronously with the threaded sleeve 24, under the action of centrifugal force, the soil at the insertion position is easily splashed as the cone 26 is inserted, reducing the compaction of the soil layer at the insertion position. Compared with direct insertion into the soil layer, its support stability is relatively weak, which can easily affect the stability of the subsequent use of the support.

[0052] Specific implementation method three: Combining Figures 1 to 10 and Figure 13 This embodiment differs from Specific Embodiment Two in that a folding support leg assembly 7 for supporting the cone 26 is installed on the transition block 25, and a steering seat 52 for steering is rotatably connected to the end of the folding arm 5. A wheel axle 53 is rotatably connected to the steering seat 52. Other components and connections are the same as in Specific Embodiment Two.

[0053] In this embodiment, the addition of a steering seat 52 at the end of the folding arm 5 is to improve the steering ability and flexibility of the support during movement. The folding foot assembly 7 is provided on the transition block 25 because although the mounting base 21 and the hinge block 22 are tightly hinged, and the working angle of the support rod assembly 2 will not change in principle when no external force is applied, the folding foot assembly 7 is used to self-lock the end of the support rod assembly 2 to further ensure the support accuracy of the support rod assembly 2. The folding foot assembly 7 retains two hinged arms. The device includes a 71 and an auxiliary support leg 72. Two hinged arms 71 are positioned opposite each other on either side of the transition block 25, with one end of each arm damped or fixedly connected to the transition block 25. One end of the auxiliary support leg 72 is positioned between the two hinged arms 71 and dampedly hinged to them via a pin. This allows the auxiliary support leg 72 to swing relative to the cone 26. When the cone 26 penetrates the soil at the bottom of the trench, the auxiliary support leg 72 swings downwards, causing its other end to contact the soil and provide support between the soil and the cone 26. Figure 9 As shown, the cone 26, the auxiliary support foot 72, and the soil layer form a triangular structure, which helps to improve the support stability at the end of the support rod assembly 2.

[0054] Specific implementation method four: Combination Figures 1 to 10 and Figure 14 This embodiment differs from Specific Embodiment Three in that the side wall at the bottom of the vertical support rod 3 is provided with a limiting structure to stabilize the folded wheel assembly 5 in its folded state, and the limiting plate 4 is provided with a limiting structure to stabilize the unfolded state of the folded wheel assembly 5. Other components and connection methods are the same as in Specific Embodiment Three.

[0055] In this embodiment, a limiting structure is used to ensure the accuracy of the folding wheel assembly 5 in both the folded and working states. A magnetic base 9 is used to maintain the stability of the folded wheel assembly 5. The magnetic base 9 is fixed to the side wall at the bottom of the vertical support rod 3. The folding arm 51 is made of metal. When the folding arm 51 is folded, it is positioned close to the vertical support rod 3 and magnetically fixed to the magnetic base 9 on the vertical support rod 3, ensuring its stability in the folded state and preventing the folding wheel assembly 5 from suddenly unfolding and disrupting the work when workers are using a surveying instrument to measure the slope. To prevent personnel from being affected, a pin structure is used to maintain the stability of the folding wheel assembly 5 in its unfolded state. First, a plug hole is machined on the hinge lug on the outer wall of the limiting plate 4, and a connecting through hole is also machined on the folding arm 51. When the folding arm 51 is in a horizontal state, the plug hole and the connecting through hole are coaxially arranged. When the folding arm 51 is in the unfolded state, the pin is inserted into the plug hole and the connecting through hole to form a limit, ensuring its stability in the unfolded state and preventing the folding wheel assembly 5 from folding back and causing a safety accident when the support encounters stones or hard objects at the bottom of the ditch during movement.

[0056] The present invention has been disclosed above with reference to preferred embodiments, but it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

[0057] Working principle

[0058] The working principle of this application is illustrated by the mobile support frame of an erosion gully slope mapping instrument provided in Specific Implementation Method 4:

[0059] First, before using the mobile support provided in this application, assemble the various components according to the connection relationship described in the specific embodiment. Install the main body 8 of the surveying instrument on the top of the surveying instrument mounting plate 1 through the mounting base. At this time, two workers are required to transport the mobile support with the main body 8 of the surveying instrument to the bottom of the erosion trench. At this time, the three support rod assemblies 2 in the closed state are used as support. One of the two workers supports the mobile support with the handle 6 to prevent it from tipping over. The other worker separates the folding arm 51 from the magnetic seat 9, adjusts it to a horizontal position, and inserts the pin to ensure its horizontal stability. At this time, the first worker controls the mobile support to tilt in the direction of the rotating wheel 54 so that the rotating wheel 54 contacts the bottom of the erosion trench. At this time, all three support rod assemblies 2 leave the bottom of the trench, and the workers can push the mobile support to move at the bottom of the trench.

[0060] Once the mobile support frame is moved to the target section mapping point, two workers straighten it. One worker removes the pin on the folding arm 51 and folds it back into the magnetic base 9, securing the folding arm 51 with magnetic attraction. Then, one worker supports the vertical support rod 3, while the other unfolds the three support rod assemblies 2 to their working angles and adjusts the working length of each assembly one by one, ensuring the cone 26 in each assembly is inserted into the soil at the bottom of the trench. Generally, two support rod assemblies 2 are inserted into the soil first, using these two as fulcrums. The working length of the third support rod assembly 2 is then adjusted based on the working lengths of these two assemblies. During the adjustment process, the supporting workers... Personnel observe the level on top of the surveyor mounting plate 1 to guide the workers responsible for adjusting the length of the support rod assembly 2. Once the surveyor mounting plate 1 is found to be horizontal and the ends of the three support rod assemblies 2 are inserted into the bottom soil layer, the workers responsible for adjusting the support rod assemblies 2 adjust the folding support leg assembly 7 on each support rod assembly 2 so that each auxiliary support leg 72 is supported on the upper part of the soil layer, thus ensuring the stability of the three support rod assemblies 2. At this time, the slope surveyor is set up, and the workers can conduct slope structure surveying on the pre-selected cross-section. After the surveying is completed, the mobile support is readjusted to the mobile state and moved to the next surveying point for slope measurement. Repeating the above operation will complete the measurement of the slope in the entire erosion gully.
