Description

Technical Field

[0001] This utility model belongs to the field of engineering measurement devices, and in particular relates to a measuring instrument for engineering surveying. Background Technology

[0002] Before construction begins, a site survey is required to identify, analyze, and evaluate the geological and geographical characteristics and geotechnical conditions of the construction site, ensuring the safe progress of subsequent construction. Leveling instruments are used to assist in the survey process.

[0003] Chinese patent CN221527681U discloses a level measuring instrument for construction engineering surveying, comprising: a base plate; a measuring instrument body disposed on the top of the base plate; a base disposed on the bottom of the measuring instrument body; a support cylinder disposed at the bottom edge of the base plate; a support foot disposed at the bottom of the support cylinder; a positioning sleeve disposed at the middle position of the top of the base plate; an assembly block disposed at the middle position of the bottom of the base; receiving grooves disposed at both ends of the assembly block; a return spring disposed at one end of the receiving groove; a connecting piece disposed at one end of the return spring; a stabilizing rod disposed at one end of the connecting piece; connecting through holes disposed at both ends of the inner sidewall of the positioning sleeve; and an adjustment component disposed between the bottom of the support cylinder and the top of the support foot. When adjusting the height of the measuring instrument body, this device requires sequentially adjusting the lifting rods within the support cylinder, which is cumbersome and makes it difficult to ensure that the measuring instrument body remains level after adjusting multiple lifting rods. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a measuring instrument for engineering surveys. By adjusting the distance between the platform and the connecting seat through the lifting structure at the bottom of the platform, the height of the main body of the measuring device can be adjusted. This adjustment is convenient and eliminates the need to readjust each support leg individually. It also avoids tilting or displacement of the main body of the measuring device during the adjustment process, which would affect the measurement accuracy and stability.

[0005] In view of this, the present invention provides a measuring instrument for engineering surveying, including a support and a measuring device body, and a platform for placing the measuring device body. The bottom of the platform is connected to a lifting structure that passes through the top connecting seat of the support. The lifting structure can adjust the distance between the platform and the connecting seat.

[0006] In this technical solution, during measurement, the support is fixed on the ground. When the height of the main body of the measuring device needs to be adjusted, the height of the main body of the measuring device is adjusted by adjusting the distance between the platform and the connecting seat through the lifting structure at the bottom of the platform. The adjustment is convenient and does not require individual adjustment of each support leg. It also avoids the main body of the measuring device from tilting or shifting during the adjustment process, which would affect the measurement accuracy and stability.

[0007] In the above technical solution, the lifting structure further includes an adjusting screw, which is vertically inserted and threadedly connected to the connecting seat. One end of the adjusting screw is rotatably connected to a shaft seat fixedly installed at the bottom of the platform, and the other end passes through the connecting seat and is provided with a first rotating block at the end. A fixing rod is vertically inserted through the connecting seat, and the top of the fixing rod is fixedly connected to the bottom of the platform.

[0008] In this technical solution, by rotating the first knob, the platform moves up and down relative to the connecting seat. At least one fixing rod is provided, which is connected to the bottom of the platform and passes vertically through the connecting seat, thereby improving the stability of the platform. The lifting structure is simple and easy to operate.

[0009] In the above technical solution, the base further includes a base plate, and a placement platform is rotatably connected to the top of the base plate. The placement platform is used to place the main body of the measuring equipment, and a drive device is provided inside the base plate to drive the placement platform to rotate based on the base plate.

[0010] In this technical solution, the placement stage is rotatably connected to the base plate, and the base plate is equipped with a drive device to drive the base plate to rotate, thereby controlling the measurement direction of the main body of the measuring device on the placement stage. This eliminates the need to adjust the bracket or the orientation of the main body of the measuring device to adjust the measurement direction, making it more convenient.

[0011] In the above technical solution, the driving device further includes a rotating shaft coaxially connected to the seat plate. One end of the rotating shaft is fixedly connected to the bottom of the placement platform, and the other end is rotatably connected to the seat plate. A first worm gear is coaxially connected to the rotating shaft. The first worm gear meshes with a steering rod. The steering rod is rotatably connected inside the seat plate. One end of the steering rod extends out of the seat plate and is connected to a second rotating block.

[0012] In this technical solution, when it is necessary to adjust the orientation of the main body of the measuring device, the second rotating block is rotated to drive the steering rod to rotate synchronously. The steering rod meshes with the first worm gear, and the steering rod and the first worm gear mesh as a worm gear. The rotating shaft coaxially connected to the first worm gear drives the placement platform to rotate, thereby satisfying the orientation adjustment of the main body of the measuring device.

[0013] In the above technical solution, the top of the placement platform is provided with a placement slot to accommodate the main body of the measuring device, the main body of the measuring device is provided with a fixing slot, and the placement platform is provided with a locking component corresponding to the fixing slot.

[0014] In this technical solution, the main body of the measuring equipment is locked to prevent it from falling off the placement platform and causing damage to the instrument.

[0015] In the above technical solution, the locking component further includes a locking block that is slidably disposed in the first slide groove in the placement platform. The locking block includes a locking plate that can pass through the first through groove and enter the fixing groove to fix the main body of the measuring device. The side of the locking block away from the placement groove and the inner wall of the first slide groove are elastically connected by a first spring. The top of the locking block is provided with a drive plate that passes through the second through groove. The end of the drive plate away from the locking plate is folded towards the side away from the main body of the measuring device to form a handle.

[0016] In this technical solution, during installation, pull the handle outward to move the locking block along the first slide groove away from the main body of the measuring device, compressing the first spring. When the locking plate is fully retracted into the first through groove, place the main body of the measuring device into the placement groove, release the locking block, the first spring returns to its original state, and the locking plate enters the fixing groove set in the main body of the measuring device to securely fix the main body of the measuring device. During disassembly, pull the handle until the locking plate is fully retracted into the first through groove.

[0017] Furthermore, the above technical solution also includes a limiting structure, which is set on the placement platform and can limit the locking plate that has been fully retracted into the first through slot.

[0018] In the above technical solution, the limiting structure further includes a fixed column fixedly installed on the placement platform, a limiting block rotatably installed on the fixed column, the limiting block having an "L" shaped structure, and one end of the limiting block being rotatably connected to the fixed column.

[0019] In this technical solution, two locking components are set up. It is inconvenient for a single operator to disassemble and assemble the main body of the measuring device individually. A limiting structure is set up for the corresponding locking components. First, pull the locking block on one side backward to release the restriction on the main body of the measuring device on that side. Then, move the limiting block on that side so that the included angle of the limiting block abuts against the drive plate in the locking block, thus restricting the movement of the locking block. After performing the same operation on the locking block on the other side, the main body of the measuring device can be smoothly placed into or taken out of the placement slot to complete the installation or disassembly.

[0020] 1. During measurement, the support is fixed on the ground. When the height of the main body of the measuring device needs to be adjusted, the height of the main body of the measuring device can be adjusted by adjusting the distance between the platform and the connecting seat through the lifting structure at the bottom of the platform. The adjustment is convenient and does not require individual adjustment of each support leg. It also avoids the main body of the measuring device from tilting or shifting during the adjustment process, which would affect the measurement accuracy and stability.

[0021] 2. The placement platform is rotatably connected to the base plate, and the base plate is equipped with a drive device to drive the base plate to rotate, so as to control the measurement direction of the main body of the measuring device on the placement platform. The measurement direction can be adjusted without adjusting the bracket or the orientation of the main body of the measuring device, which is more convenient.

[0022] 3. The locking component allows the main body of the measuring device to be securely fixed on the placement platform, and the limiting structure allows operators to easily disassemble and assemble the main body of the measuring device independently. Attached Figure Description

[0037] First embodiment:

[0038] like Figure 1-2 As shown, this embodiment provides a measuring instrument for engineering surveying, including a support 2 and a measuring device body 1, and a platform 3 for placing the measuring device body 1. A lifting structure 4 is connected to the bottom of the platform 3, passing through a connecting seat 5 at the top of the support 2. The lifting structure 4 can adjust the distance between the platform 3 and the connecting seat 5. During measurement, the support 2 is fixed to the ground. When the height of the measuring device body 1 needs to be adjusted, the height of the measuring device body 1 can be adjusted by using the lifting structure 4 at the bottom of the platform 3 to adjust the distance between the platform 3 and the connecting seat 5. This adjustment is convenient, eliminates the need to individually adjust each leg of the support 2, and avoids tilting or displacement of the measuring device body 1 during adjustment, thus preventing any impact on measurement accuracy and stability.

[0039] like Figure 2 As shown, the lifting structure 4 includes an adjusting screw 6, which is vertically threaded through and connected to the connecting seat 5. One end of the adjusting screw 6 is rotatably connected to a shaft seat 7 fixedly mounted on the bottom of the platform 3, and the other end passes through the connecting seat 5 with a first rotating block 8 at its end. A fixing rod 9 is vertically threaded through the connecting seat 5, and the top of the fixing rod 9 is fixedly connected to the bottom of the platform 3. By rotating the first knob, the platform 3 moves up and down relative to the connecting seat 5. At least one fixing rod 9 is provided, connected to the bottom of the platform 3 and vertically threaded through the connecting seat 5, which improves the stability of the platform 3. The lifting structure 4 is simple and easy to operate.

[0040] Second embodiment:

[0041] This embodiment provides a surveying instrument for engineering exploration, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0042] like Figure 2-4 As shown, the base 3 includes a base plate 10, and a placement platform 11 is rotatably connected to the top of the base plate 10. The placement platform 11 is used to place the main body of the measuring device. A drive device is provided inside the base plate 10 to drive the placement platform 11 to rotate based on the base plate 10. The placement platform 11 is rotatably connected to the base plate 10, and the drive device is provided inside the base plate 10 to drive the base plate 10 to rotate, thereby controlling the measurement direction of the main body 1 of the measuring device on the placement platform 11. This eliminates the need to adjust the bracket 2 or the orientation of the main body 1 of the measuring device to adjust the measurement direction, making it more convenient.

[0043] The drive device includes a rotating shaft 12 coaxially connected to the base plate 10. One end of the rotating shaft 12 is fixedly connected to the bottom of the placement platform 11, and the other end is rotatably connected to the base plate 10. A first worm gear 13 is coaxially connected to the rotating shaft 12. The first worm gear meshes with a steering rod 14, which is rotatably connected inside the base plate 10. One end of the steering rod 14 extends out of the base plate 10 and is connected to a second rotating block 15. When the orientation of the measuring device body 1 needs to be adjusted, the second rotating block 15 is rotated to drive the steering rod 14 to rotate synchronously. The steering rod 14 meshes with the first worm gear 13, forming a worm gear mesh. The rotating shaft 12, coaxially connected to the first worm gear 13, drives the placement platform 11 to rotate, thus satisfying the orientation adjustment of the measuring device body 1.

[0044] Third embodiment:

[0045] This embodiment provides a surveying instrument for engineering exploration, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0046] like Figure 3 , Figure 5-7 As shown, the top of the placement platform 11 is provided with a placement slot 16 to accommodate the main body of the measuring device, and the main body of the measuring device is provided with a fixing slot 17. The placement platform 11 is provided with a locking component 18 corresponding to the fixing slot 17. The main body of the measuring device is locked to prevent it from falling off the placement platform 11 and causing damage to the instrument.

[0047] The locking assembly 18 includes a locking block 19 slidably disposed in the first slide groove 21 within the placement platform 11. The locking block 19 includes a locking plate 20 that can pass through the first through groove 22 and enter the fixing groove 17 to fix the main body of the measuring device. The side of the locking block 19 away from the placement groove 16 and the inner wall of the first slide groove 21 are elastically connected by a first spring 23. The top of the locking block 19 is provided with a drive plate 25 that passes through the second through groove 24. The end of the drive plate 25 away from the locking plate 20 is folded away from the main body of the measuring device to form a handle 26. During installation, pull the handle 26 outward to move the locking block 19 along the first slide groove 21 away from the measuring device body 1, compressing the first spring 23. When the locking plate 20 is fully retracted into the first through groove 22, place the measuring device body 1 into the placement groove 16, release the locking block 19, and the first spring 23 returns to its original state, moving the locking plate 20 into the fixing groove 17 provided in the measuring device body 1, thus securely fixing the measuring device body 1. During disassembly, pull the handle 26 until the locking plate 20 is fully retracted into the first through groove 22. The mounting groove and locking assembly 18 are symmetrically arranged in two places to prevent accidental release of the device body from being restricted by contact or other unexpected events.

[0048] like Figure 2 and Figure 6 As shown, it also includes a limiting structure 27, which is set on the placement platform 11. The limiting structure 27 can limit the locking plate 20 after it has been fully retracted into the first through slot 22. The limiting structure 27 includes a fixed post 28 fixedly set on the placement platform 11. The fixed post 28 is rotatably connected to a limiting block 29. The limiting block 29 has an "L" shape structure, and one end of the limiting block 29 is rotatably connected to the fixed post 28. Two locking components 18 are set up. It is inconvenient for a single operator to disassemble and assemble the measuring device body 1 individually. The limiting structure 27 is set up for the locking components 18. First, pull the locking block 19 on one side backward to release the restriction on the measuring device body 1 on that side. Then, move the limiting block 29 on that side so that the included angle of the limiting block 29 abuts against the drive plate 25 in the locking block 19, restricting the movement of the locking block 19. After performing the same operation on the locking block 19 on the other side, the measuring device body 1 can be smoothly placed into or removed from the placement slot 16 to complete the installation or disassembly.

[0049] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
