Description

Technical Field

[0001] This utility model belongs to the field of construction engineering surveying, specifically, it relates to a level measuring instrument for construction engineering surveying. Background Technology

[0002] Before construction begins, an on-site survey of the construction site is required to identify, analyze, and evaluate the geological and geographical environmental characteristics and geotechnical engineering conditions of the construction site according to the requirements of the construction project, so as to ensure the safe progress of the subsequent construction project. Horizontal measuring instruments are needed to assist in the survey work.

[0003] Existing level measuring instruments are all fixedly mounted on brackets, which makes them inconvenient to carry or disassemble for repair when the instrument is damaged. There is a technical problem that the measuring instrument body cannot be easily and quickly disassembled for inspection or carrying. Chinese patent with publication number CN221527681U discloses a level measuring instrument for construction engineering survey, and the above patent proves the objective existence of this shortcoming.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a level measuring instrument for construction engineering survey, which solves the technical problem in the prior art that the measuring instrument body cannot be easily and quickly disassembled for maintenance or carried.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A level measuring instrument for construction engineering survey includes: a level measuring device body, a locking block installed at the bottom of the level measuring device body, a fixing block provided on the surface of the locking block, a fixing device installed inside the fixing block, a support plate installed at the bottom of the fixing block, and an adjustment device installed inside the support plate.

[0008] The fixing device includes a pressure rod, a sliding groove inside the fixing block, the pressure rod slidingly engaging inside the sliding groove, a telescopic rod at the bottom of the pressure rod, a second spring inside the sliding groove, the end of the second spring near the pressure rod being fixedly connected to the pressure rod, two L-shaped fixing plates slidingly engaging inside the sliding groove, the L-shaped fixing plates having a moving groove inside, the pressure rod slidingly engaging with the L-shaped fixing plates through the moving groove, a pull rod on one side of the L-shaped fixing plate, one side of the pull rod extending to the outside of the fixing block, a first spring inside the fixing block, the end of the first spring near the L-shaped fixing plate being fixedly connected to the L-shaped fixing plate.

[0009] Optionally, slots are provided on both sides of the card block, and the L-shaped fixing plate is engaged with the card block through the slots.

[0010] Optionally, the support plate has three supporting legs that rotate internally, and a fixed column is installed at the bottom of the support plate. Three electric push rods are installed on the surface of the fixed column, and one end of the electric push rod rotates with the supporting leg.

[0011] Optionally, a handle is installed on the top of the main body of the leveling device.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0013] When the operator moves the main body of the horizontal measuring equipment, the locking block moves. When the locking block contacts the pressure rod, the pressure rod moves to the corresponding position in the moving slot. Under the action of spring one, the L-shaped fixing plate moves into the slot, thus fixing the locking block. Pulling the pull rod causes the L-shaped fixing plate to disengage from the slot, allowing the locking block to be disassembled. This makes it convenient for operators to carry or replace the measuring instrument when it is damaged. It also allows for quick disassembly and assembly of the measuring instrument for maintenance or carrying.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Please see Figure 1-4 As shown, this embodiment provides a level measuring instrument for construction engineering survey, including a level measuring device body 1, a locking block 10 installed at the bottom of the level measuring device body 1, a fixing block 4 provided on the surface of the locking block 10, a fixing device installed inside the fixing block 4, a support plate 3 installed at the bottom of the fixing block 4, and an adjustment device installed inside the support plate 3.

[0025] The fixing device includes a pressure rod 12, and a sliding groove 23 is provided inside the fixing block 4. The pressure rod 12 is slidably fitted inside the sliding groove 23. A telescopic rod 13 is installed at the bottom of the pressure rod 12. A second spring 17 is installed inside the sliding groove 23. The end of the second spring 17 near the pressure rod 12 is fixedly connected to the pressure rod 12. Two L-shaped fixing plates 14 are slidably fitted inside the sliding groove 23. A moving groove 15 is provided inside the L-shaped fixing plate 14. The pressure rod 12 is slidably fitted with the L-shaped fixing plate 14 through the moving groove 15. A pull rod 5 is installed on one side of the L-shaped fixing plate 14. One side of the pull rod 5 extends to the outside of the fixing block 4. A first spring 16 is installed inside the fixing block 4. The end of the first spring 16 near the L-shaped fixing plate 14 is fixedly connected to the L-shaped fixing plate 14.

[0026] One application of this embodiment is as follows: When the main body 1 of the horizontal measuring device is damaged and needs to be replaced, the worker pulls the pull rod 5. The movement of the pull rod 5 moves the L-shaped fixing plate 14, causing the L-shaped fixing plate 14 to disengage from the inside of the slot 11, thereby releasing the restriction on the slot 11. At this time, the worker can move the main body 1 of the horizontal measuring device out of the inside of the fixing block 4 by pulling the handle 2, thereby replacing the damaged main body 1 of the horizontal measuring device. When it is necessary to install the main body 1 of the horizontal measuring device, the worker moves the main body 1 of the horizontal measuring device. The movement of the main body 1 of the horizontal measuring device moves the locking block 10. When the locking block 10 moves into the inside of the slide groove 23, it contacts the pressure rod 12. The movement of the locking block 10 moves the pressure rod 12. When the pressure rod 12 moves to the position corresponding to the moving groove 15, the L-shaped fixing plate 14 moves under the action of the spring 16. When the L-shaped fixing plate 14 moves into the inside of the slot 11, the locking block 10 is fixed, thereby completing the installation of the main body 1 of the horizontal measuring device. When it is necessary to install the L-shaped fixing plate 14, the worker can then proceed with the installation of the L-shaped fixing plate 14. When adjusting the horizontal measuring equipment body 1 left and right, the operator rotates the rotating rod 9. The rotation of the rotating rod 9 drives the first bevel gear 18 to rotate, which in turn drives the second bevel gear 19 to rotate. The second bevel gear 19 then drives the transmission rod 20 to rotate, which in turn drives the support plate 3 to rotate. The support plate 3 then drives the fixing block 4 to rotate, which in turn drives the horizontal measuring equipment body 1 to rotate. This completes the adjustment of the horizontal measuring equipment body 1. The operator then activates the electric push rod 7. The movement of the end of the electric push rod 7 pushes the support legs 8 to rotate inside the support plate 3, causing the three support legs 8 to open, thereby adjusting the height of the horizontal measuring equipment body 1. The carrying handle 2 facilitates the operator's carrying of the horizontal measuring equipment body 1, thus increasing its usability. The first limit block 21 limits the rotation rod 9, improving its stability during operation. The second limit block 22 limits the transmission rod 20, improving its stability during operation.

[0027] The adjustment device in this embodiment includes a rotating rod 9, which is rotatably fitted inside a support plate 3. A bevel gear 18 is mounted on the surface of the support plate 3, and a bevel gear 19 meshes with the surface of the bevel gear 18. A transmission rod 20 is installed inside the bevel gear 19, and one end of the transmission rod 20 extending to the outside of the support plate 3 is fixedly connected to a fixing block 4. When the operator rotates the rotating rod 9, the rotation of the rotating rod 9 drives the bevel gear 18 to rotate, which in turn drives the bevel gear 19 to rotate, which in turn drives the transmission rod 20 to rotate, which in turn drives the support plate 3 to rotate, which in turn drives the fixing block 4 to rotate, which in turn drives the main body 1 of the horizontal measuring equipment to rotate, thereby completing the adjustment of the main body 1 of the horizontal measuring equipment.

[0028] In this embodiment, the support plate 3 is equipped with two limiting blocks 21, which are rotatably engaged with the rotating rod 9. The support plate 3 is also equipped with a second limiting block 22, which is rotatably engaged with the transmission rod 20. By setting the first limiting block 21, the rotating rod 9 can be limited, improving its stability during operation. Similarly, by setting the second limiting block 22, the transmission rod 20 can be limited, further improving its stability during operation.

[0029] In this embodiment, the locking block 10 has locking slots 11 on both sides, and the L-shaped fixing plate 14 is engaged with the locking block 10 through the locking slots 11. The movement of the locking block 10 drives the pressure rod 12 to move. When the pressure rod 12 moves to correspond to the moving slot 15, the L-shaped fixing plate 14 moves under the action of the spring 16. When the L-shaped fixing plate 14 moves into the inside of the locking slot 11, the locking block 10 is fixed.

[0030] In this embodiment, the support plate 3 has three rotatable support legs 8. A fixed column 6 is installed at the bottom of the support plate 3, and three electric push rods 7 are installed on the surface of the fixed column 6. One end of each electric push rod 7 is rotatably engaged with a support leg 8. When the operator activates the electric push rod 7, the end of the electric push rod 7 moves, causing the support legs 8 to rotate inside the support plate 3, thus opening the three support legs 8 and adjusting the height of the horizontal measuring device body 1.
