Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering surveying equipment technology, and in particular to a support for an engineering cost level instrument. Background Technology
[0002] In the process of engineering cost measurement, the level is a commonly used measuring instrument, and the level support is a key component that supports the level, the performance of which directly affects the accuracy of the measurement and the efficiency of the work.
[0003] Existing leveling instrument supports have several shortcomings. First, their adjustment functions are limited and the adjustment methods are cumbersome. For example, if bolt fastening is used, each adjustment requires a significant amount of time to tighten the bolts, making it difficult to quickly adapt to different measurement heights and terrain requirements. Second, they lack versatility. Some supports have fixed connection methods with the leveling instrument, making them incompatible with different models and specifications of leveling instruments, thus limiting their application range. Furthermore, some supports have unreasonable structural designs, are bulky, and inconvenient to carry and transport, increasing the burden on engineering cost measurement work.
[0004] To address the above issues, we have introduced a support for an engineering cost level instrument. Utility Model Content
[0005] This utility model discloses a support for an engineering cost level instrument, which aims to solve the technical problems in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A support plate for an engineering cost leveling instrument includes a support plate with a triangular structure. Three legs are symmetrically and rotatably connected to the bottom of the support plate. A first gear is rotatably connected to the top of the support plate. A threaded rod is threaded into the interior of the first gear. A leveling instrument platform is rotatably connected to the top of the threaded rod. A connecting block is fixedly connected to the bottom of the threaded rod, penetrating the support plate. Three connecting rods are symmetrically and rotatably connected to the outer side of the connecting block. The ends of the connecting rods furthest from the connecting block are rotatably connected to the outer side of their corresponding legs. A first motor is fixedly connected to the bottom of the support plate. The output shaft of the first motor penetrates the support plate and is fixedly connected to a second gear, which meshes with the first gear.
[0008] When used on the construction site, the first motor is started, which drives the second gear to rotate. Through meshing, the first gear rotates, which in turn drives the threaded rod to rise and fall. At the same time, the connecting block at the bottom of the threaded rod, through the connecting rod, allows the three legs to adjust their tilt angles synchronously, quickly adjusting the leveling instrument platform to a horizontal state.
[0009] In a preferred embodiment, the bottom of each leg is detachably connected to a connecting plate by screws, and the bottom of each connecting plate is connected to different casters and limit cones, with different casters and limit cones used in different usage scenarios.
[0010] When measuring on flat indoor ground, install casters on the bottom of the connecting plate to facilitate the movement of the support; when working on soft ground such as outdoor soil, remove the casters and replace them with limit cones, insert them into the ground to enhance the stability of the support and prevent the support from shifting during the measurement process.
[0011] In a preferred embodiment, the top of the leveling instrument platform is provided with a sliding groove, and a bidirectional lead screw is rotatably connected inside the sliding groove. Two sliding blocks are threaded to the outside of the bidirectional lead screw, and a clamping plate is fixedly connected to the top of each sliding block. A second motor is fixedly connected to one side of the leveling instrument platform, and the output shaft of the second motor extends into the sliding groove and is fixedly connected to one end of the bidirectional lead screw.
[0012] After placing the level on the leveling platform, start the second motor, which drives the bidirectional lead screw to rotate, causing the two sliding blocks to move the clamping plate synchronously toward the level until the level is firmly clamped, preventing the level from shaking during the measurement process and affecting the accuracy of the data.
[0013] In a preferred embodiment, both sides of the top of the level instrument platform are fixedly connected to limit slide rails, and the clamping plates are slidably connected to the limit slide rails.
[0014] When the clamping plate is driven to move by the bidirectional lead screw, the limiting slide rail plays a limiting and guiding role for the clamping plate, ensuring that the clamping plate moves smoothly and linearly, accurately clamping the level, and preventing the clamping plate from shifting and failing to effectively fix the level.
[0015] In a preferred embodiment, anti-slip pads are fixedly connected to the adjacent sides of both clamping plates.
[0016] When the clamping plate clamps the level, the anti-slip pad increases the friction between the level and the level, further improving the level's stability without damaging the level's outer casing. Even in environments with slight vibrations, it ensures that the level will not slide or shift.
[0017] In a preferred embodiment, two control buttons are fixedly connected to one side of the support plate, and the first motor and the second motor are both electrically connected to the corresponding control buttons.
[0018] On-site surveyors can conveniently control the first motor to adjust the horizontal height of the support bracket and the angle of the legs by pressing the control button on one side of the support plate, and control the second motor to drive the clamping plate to clamp or release the level, thus achieving fast and accurate operation.
[0019] The engineering cost leveling instrument bracket provided by this utility model has the following advantages:
[0020] In this invention, a triangular support plate is paired with three legs and a threaded rod. Driven by a first motor, the threaded rod drives the connecting block and connecting rod to adjust the angle of the legs, enabling stability on various uneven surfaces, effectively preventing slippage and swaying, providing reliable support for the level instrument, ensuring the accuracy of measurement data, and allowing surveyors to quickly and conveniently adjust the position and angle of the level instrument, thus improving measurement efficiency. Compared with traditional devices, this invention greatly improves the quality of work and efficiency of use. Attached Figure Description

[0030] The engineering cost leveling instrument bracket disclosed in this utility model is mainly used in the scenario of building engineering surveying equipment.
[0031] Reference Figures 1-7 A support plate for an engineering cost leveling instrument includes a support plate 1, which is triangular in structure. Three legs 2 are symmetrically and rotatably connected to the bottom of the support plate 1. A first gear 3 is rotatably connected to the top of the support plate 1. A threaded rod 4 is threadedly connected to the inside of the first gear 3. A leveling instrument placement platform 9 is rotatably connected to the top of the threaded rod 4. A connecting block 5 is fixedly connected to the bottom of the threaded rod 4 through the support plate 1. Three connecting rods 6 are symmetrically and rotatably connected to the outside of the connecting block 5. The ends of the connecting rods 6 away from the connecting block 5 are rotatably connected to the outside of the corresponding legs 2. A first motor 7 is fixedly connected to the bottom of the support plate 1. The output shaft of the first motor 7 passes through the support plate 1 and is fixedly connected to a second gear 8. The second gear 8 meshes with the first gear 3.
[0032] In this embodiment, when used on the construction site, the first motor 7 is started, which drives the second gear 8 to rotate. Through meshing, the first gear 3 rotates, which in turn drives the threaded rod 4 to rise and fall. At the same time, the connecting block 5 at the bottom of the threaded rod 4, through the connecting rod 6, allows the three legs 2 to adjust their tilt angles synchronously, quickly adjusting the level instrument platform 9 to a horizontal state.
[0033] In a preferred embodiment, the bottom of each foot stick 2 is detachably connected to a connecting plate 10 by screws. The bottom of the connecting plate 10 is connected to different casters 11 and limiting cones 12, and different casters 11 and limiting cones 12 are used in different usage scenarios.
[0034] In this embodiment: when measuring on a flat indoor site, casters 11 are installed on the bottom of the connecting plate 10 to facilitate the movement of the support; when working on soft outdoor sites such as soil, the casters 11 are removed and replaced with limit cones 12, which are inserted into the ground to enhance the stability of the support and prevent the support from shifting during the measurement process.
[0035] In a preferred embodiment, a sliding groove 13 is provided on the top of the level instrument placement platform 9. A bidirectional lead screw 14 is rotatably connected inside the sliding groove 13. Two sliding blocks 15 are threadedly connected to the outside of the bidirectional lead screw 14. A clamping plate 16 is fixedly connected to the top of each sliding block 15. A second motor 17 is fixedly connected to one side of the level instrument placement platform 9. The output shaft of the second motor 17 extends into the sliding groove 13 and is fixedly connected to one end of the bidirectional lead screw 14.
[0036] In this embodiment: After placing the level instrument on the level instrument placement platform 9, the second motor 17 is started, which drives the bidirectional lead screw 14 to rotate, causing the two sliding blocks 15 to move the clamping plate 16 synchronously toward the level instrument until the level instrument is firmly clamped, thus preventing the level instrument from shaking during the measurement process and affecting the accuracy of the data.
[0037] In a preferred embodiment, both sides of the top of the level instrument placement platform 9 are fixedly connected to limit slide rails 18, and the clamping plates 16 are slidably connected to the limit slide rails 18.
[0038] In this embodiment, when the clamping plate 16 is driven to move by the bidirectional lead screw 14, the limiting slide rail 18 plays a limiting and guiding role on the clamping plate 16, ensuring that the clamping plate 16 moves smoothly and linearly, accurately clamping the level, and preventing the clamping plate 16 from shifting and failing to effectively fix the level.
[0039] In a preferred embodiment, anti-slip pads 19 are fixedly connected to the adjacent sides of the two clamping plates 16.
[0040] In this embodiment, when the clamping plate 16 clamps the level, the anti-slip pad 19 increases the friction between itself and the level, further improving the level's stability without damaging its outer casing. Even in environments with slight vibrations, the level will not slide or shift.
[0041] In a preferred embodiment, two control buttons 20 are fixedly connected to one side of the support plate 1, and the first motor 7 and the second motor 17 are electrically connected to the corresponding control buttons 20.
[0042] In this embodiment, the surveyor can conveniently control the first motor 7 to adjust the horizontal height of the support and the angle of the foot rod 2 by pressing the control button 20 on one side of the support plate 1, and control the second motor 17 to drive the clamping plate 16 to clamp or release the level, thus achieving fast and accurate operation.
[0043] Working principle: When using this bracket, the support plate 1 is stably placed on the ground via the foot rods 2 and the connecting plate 10. Depending on the usage scenario, either casters 11 or limiting cones 12 are installed at the bottom of the connecting plate 10. The casters 11 facilitate movement, while the limiting cones 12 are used for fixation. The first motor 7 drives the second gear 8 to rotate, which in turn drives the first gear 3 to rotate. The first gear 3, via the threaded rod 4, drives the connecting block 5 to move up and down. The connecting block 5, via the connecting rod 6, adjusts the angle of the foot rods 2 to ensure the stability of the bracket. The top of the threaded rod 4 is level. The instrument placement platform 9 adjusts the position of the clamping plate 16 via the bidirectional lead screw 14 and sliding block 15 in the sliding groove 13. The second motor 17 drives the bidirectional lead screw 14 to rotate, and the sliding block 15 slides within the limit slide rail 18. The clamping plate 16 clamps the level instrument via the anti-slip pad 19, ensuring the level instrument is placed stably. The control button controls the operation of the first motor 7 and the second motor 17, enabling rapid adjustment of the support and stable clamping of the level instrument. This achieves efficient and stable support for the engineering cost level instrument, ensuring measurement accuracy and ease of operation.
