Description

Technical Field

[0001] This utility model provides a high-precision building construction surveying and setting-out device, belonging to the field of building construction technology. Background Technology

[0002] In the field of construction, surveying and setting out are crucial steps to ensure the accurate implementation of building projects according to design requirements. High-precision surveying and setting out devices play a vital role in guaranteeing construction quality and efficiency. Among these, the rangefinder, as one of the core components of such devices, is widely used in distance measurement. The installation of a rangefinder typically includes a base and a support frame to hold the rangefinder at a certain height.

[0003] However, existing high-precision construction surveying and setting-out devices still have some problems in practical use. To ensure the stability of the device during the measurement process, when the surveying and setting-out device needs to be set in soft soil, some devices have a rod inserted into the soil at the bottom of the base for fixation. This method uses the friction between the rod and the soil to increase the stability of the measuring device. During insertion, the entire rod often needs to be fully inserted into the soil before the base contacts the ground to ensure the stability of the device. If the base is not in contact with the ground, the entire device is still prone to sinking under the influence of gravity, thus affecting the accuracy of the surveying and setting-out. Since the length of the rod is fixed in the initial design, the insertion depth is often fixed and cannot be flexibly adjusted according to different geological conditions and actual needs. On some soft soil, a shallow depth is insufficient to provide enough stability, causing the device to shake during the measurement process, thus affecting the measurement accuracy. On relatively hard soil, an excessively deep insertion depth can make it difficult to insert the rod, or even damage the rod or the device itself.

[0004] Furthermore, the rangefinder, as a crucial and easily damaged component in the surveying and setting-out apparatus, requires convenient disassembly and installation. However, in existing systems, disassembling the rangefinder often necessitates tightening multiple sets of threaded connections. In practice, this not only consumes a significant amount of time and effort but also reduces work efficiency.

[0005] In summary, existing high-precision building construction surveying and setting-out devices have significant shortcomings in terms of adjusting the insertion depth of the insertion rod and disassembling the rangefinder. Improvements and innovations are needed to enhance the practicality and efficiency of the devices and better meet the actual needs of building construction surveying and setting-out. Utility Model Content

[0006] The technical problem this invention aims to solve is that the insertion depth of the insertion rod is inconvenient to adjust, thus affecting the accuracy of measurement and layout; at the same time, the disassembly efficiency of the rangefinder is low.

[0007] To solve the above problems, the proposed technical solution is as follows: a high-precision building construction surveying and setting-out device, comprising a base, with a support rod and a support frame fixedly connected upwards from the base, and a rangefinder located on the support frame; a rod capable of being inserted into the ground is fixedly installed below the base; and further comprising:

[0009] Adjustment plate; The adjustment plate, which can adjust the depth of the insertion of the rod into the ground, is slidably sleeved on the rod, and the adjustment plate is fixedly connected to the upper and lower sliding mechanism.

[0010] As an improvement, four insertion rods are provided, and the four insertion rods are respectively located at the four corners of the base; the adjustment plate is located below the base, and the adjustment plate is slidably sleeved on all the insertion rods.

[0011] As an improvement, the up-and-down sliding mechanism includes a screw and a slider; the screw is rotatably disposed in a slide groove, the slider is slidably disposed in the slide groove, and the slider is threadedly connected to the screw; a connecting rod is fixedly connected below the slider, and the connecting rod is fixedly connected to the adjusting plate.

[0012] As an improvement, the slide groove is a cuboid structure, the slider is a cuboid structure corresponding to the slide groove, and the slider and the inner wall of the slide groove are in close contact with each other; the inner wall of the slide groove is fixedly connected to a limiting plate.

[0013] As an improvement, the fixing component is a fixing rod; the fixing rod is fixedly connected to the slider, and the fixing rod extends out of the base and is inserted into the socket.

[0014] As an improvement, a base plate is fixedly connected to the lower end of the rangefinder, and the base plate is fixedly connected to the locking block.

[0015] The beneficial effects of this utility model are:

[0016] 1.

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

[0024] according to Figure 1-4 As shown: This utility model provides a high-precision building construction surveying and setting-out device: including a base 1, with a support rod 2 and a support frame 3 fixedly connected to the base 1 in sequence, and a rangefinder 4 located on the support frame 3; a rod 8 that can be inserted into the ground is fixedly installed below the base 1; there are four rods 8, and the four rods 8 are respectively installed at the four corners of the base 1 to increase the stability of the overall device.

[0025] like Figure 3 As shown, a sliding groove 10 is provided inside the base 1, and the upper and lower sliding mechanism is slidably disposed within the sliding groove 10; an adjusting plate 9, which can adjust the insertion depth of the insertion rod 8 into the soil, is slidably sleeved on the insertion rod 8, and the adjusting plate 9 is fixedly connected to the upper and lower sliding mechanism. The adjusting plate 9 is located below the base 1, and the adjusting plate 9 is slidably sleeved on all the insertion rods 8.

[0026] The sliding mechanism includes a screw 11 and a slider 12; the screw 11 is rotatably disposed in the slide groove 10, the slider 12 is slidably disposed in the slide groove 10, and the slider 12 is threadedly connected to the screw 11; a connecting rod 13 is fixedly connected below the slider 12, and the connecting rod 13 is fixedly connected to the adjusting plate 9.

[0027] The slide groove 10 is a cuboid structure, and the slider 12 is a cuboid structure corresponding to the slide groove 10. The slider 12 and the inner wall of the slide groove 10 are in close contact with each other, which can restrict the rotation of the slider 12, thereby converting the rotation of the screw 11 into the movement of the slider 12. The inner wall of the slide groove 10 is fixedly connected to the limiting plate 14 to prevent the slider 12 from detaching from the slide groove 10.

[0028] like Figure 2 , 4 As shown, a slot 6 is provided inside the support frame 3, and a locking block 7, which is fixedly connected to the rangefinder 4, is inserted into the slot 6. The locking block 7 and the slot 6 limit the vertical movement of the rangefinder 4. A base plate 5 is fixedly connected to the lower end of the rangefinder 4, and the base plate 5 is fixedly connected to the locking block 7. An insertion hole 15 is provided below the locking block 7, and a fixing component for inserting into the insertion hole 15 is fixedly connected to the upper and lower sliding mechanism. The fixing component is a fixing rod 16. The fixing rod 16 is fixedly connected to the slider 12, and the fixing rod 16 extends out of the base 1 and inserts into the insertion hole 15, which can limit the horizontal movement of the rangefinder 4, thereby completely fixing the rangefinder 4. By setting the slider 12, not only can the position of the adjusting plate 9 be adjusted, thereby adjusting the depth to which the insertion rod 8 can be inserted into the ground; the sliding of the slider 12 can also be used to fix or remove the locking block 7, thereby improving the disassembly efficiency of the rangefinder 4.

[0029] The principle of this utility model

[0030] like Figure 3 As shown, before using this application, the depth of the insertion rod 8 into the soil should be adjusted according to the actual working conditions. Tightening the screw 11 allows the adjusting plate 9, which is fitted onto the insertion rod 8, to slide up and down under the action of the slider 12. The length of the insertion rod 8 below the adjusting plate 9 is the desired insertion depth. In use, simply insert the insertion rod 8 below the adjusting plate 9 into the soil, and then align the adjusting plate 9 with the soil, replacing the base 1. It should be noted that when the slider 12 moves the adjusting plate 9 downwards, the fixing rod 16 will also slide downwards. By designing the depth of the insertion hole 15, the fixing rod 16 will only disengage from the insertion hole 15 when the adjusting plate 9 slides downwards and is about to disengage from the insertion rod 8. Therefore, adjusting the position of the adjusting plate 9 will not affect the stability of the fixing rod 16 in fixing the rangefinder 4.

[0031] When it is necessary to disassemble the rangefinder 4, such as Figure 3 , 4 As shown, by turning the screw 11, the slider 12 drives the fixing rod 16 to move down until the fixing rod 16 disengages from the insertion hole 15 and contacts the fixing of the card block 7; then the card block 7 is slid out from the card slot 6, and the disassembly of the card block 7 and the rangefinder 4 is quickly completed without turning multiple sets of threaded structures, which facilitates the maintenance of the rangefinder 4.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
