Description

Technical Field

[0001] This utility model relates to the field of land surveying technology, and in particular to a protective soil layer thickness measuring device for surveying. Background Technology

[0002] Soil thickness measurement is a type of land surveying work. It is an essential task in industrial and agricultural construction and various civil engineering projects. By measuring the soil thickness, the construction depth of industrial and agricultural construction and various civil engineering projects can be roughly determined, preventing excessive construction depth from damaging the groundwater system and causing environmental pollution. When measuring soil thickness, a measuring device is needed to measure it, which facilitates subsequent operations.

[0003] In a land surveying soil thickness measuring device with announcement number CN220708268U, specifically relating to the field of land surveying technology, the device includes a rotating component and a drill rod fixed to its rotating end. It also includes: a support frame sleeved around the rotating component; a movable rod fixedly connected to the rotating component and slidably connected to the support frame; scale lines equidistantly arranged on the front end face of the support frame; an indicator needle fixedly connected to the bottom end of the rotating component; and a base fixedly connected to the bottom end of the support frame, which is wrapped around the drill rod. This invention effectively avoids the need for existing devices to stop driving the rotating component before measuring the drill rod to obtain data, allowing operators to observe the drilling depth in real time and increasing the accuracy of the device.

[0004] However, the above-mentioned soil thickness measuring device for land surveying still has the following drawbacks: When using the existing technology, the operator manually presses down the moving rod, which causes the rotating part and the drill rod to move downward with the support frame, thereby measuring the soil thickness. However, in actual use, the above operation not only increases the labor intensity of the operator, but also reduces the efficiency of soil thickness measurement. Utility Model Content

[0005] The purpose of this invention is to provide a protective soil thickness measuring device for surveying, so as to solve the problem mentioned in the background art that existing soil thickness measuring devices for surveying require manual measurement during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective surveying soil thickness measuring device, comprising a base, support rods, a hydraulic telescopic seat, and traveling wheels. Support rods are welded to both sides of the top of the base, and traveling wheels are fixed to both sides of the bottom of the base. A hydraulic telescopic seat is welded to the bottom of the base on one side of the traveling wheel.

[0007] The base has a protective cover at its bottom, and limit mechanisms are provided on both sides of the protective cover. One of the support rods has an adjustment mechanism on one side, and a guide rod is fixed to one side of the other support rod. The guide rod has scale lines on its outer side. A movable block is sleeved on the outer side of the guide rod, and a moving block is fixed to one side of the movable block. A servo motor is provided at the top of the moving block, and a drill rod is provided at the bottom of the servo motor. An adjustment block is fixed to one side of the servo motor. A guide groove is provided at the top of the base, and a guide block is slidably arranged inside the guide groove.

[0008] When using a protective surveying soil thickness measuring device according to this technical solution, the device is equipped with an adjustment mechanism that enables automatic measurement under the action of the adjustment block and the moving block, thereby reducing the labor intensity of the staff and improving its practicality.

[0009] Preferably, the adjustment mechanism includes an adjustment motor, which is located at the top of the support rod. An adjustment shaft is fixed at the bottom of the adjustment motor, and a drive gear is sleeved on the outside of the adjustment shaft. A driven gear meshes with one side of the drive gear, and a through hole is opened inside the driven gear. A cleaning brush is evenly adhered inside the through hole.

[0010] Preferably, there are multiple cleaning brushes arranged in a ring, and all of the cleaning brushes are made of rubber.

[0011] Preferably, the limiting mechanism includes a fixing block, which is disposed at the bottom end of the base. An adjusting rod is disposed inside the fixing block, and one end of the adjusting rod extends to the outside of the fixing block. A return spring is evenly wound around the outside of the adjusting rod. A baffle is fixed to one side of the adjusting rod, and sliders are disposed on both sides of the baffle. A sliding groove is disposed on the outside of each slider, and the sliding groove is opened inside the fixing block. A limiting rod is fixed to one side of the baffle.

[0012] Preferably, the slider slides inside the groove, and the baffle is slidably connected to the fixed block through the slider and the groove.

[0013] Preferably, there are two reset springs, which are symmetrically distributed and are both in a stretched state inside the fixing block.

[0014] Preferably, there are two guide blocks, which are symmetrically distributed and have T-shaped cross sections.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the protective surveying soil thickness measuring device can not only perform automatic measurement, but also has a protective function;

[0016] 1. By starting the adjusting motor, the adjusting block is driven to descend under the action of the adjusting shaft. Under the action of the movable block and the moving block, the drill rod is driven to descend synchronously. With the cooperation of the movable block, the thickness of the soil layer can be measured. The above operation facilitates the automatic measurement of the soil layer, thereby reducing the labor intensity of the workers and improving the efficiency of soil layer thickness measurement.

[0017] By starting the regulating motor, the driving gear is driven to rotate under the action of the regulating shaft. Since the driving gear and the driven gear mesh with each other, the driving gear rotates while driving the cleaning brush to rotate synchronously. The above operation makes it easy to clean the mud attached to the drill rod, thereby improving its practicality.

[0018] 2. By pushing the protective cover, it is inserted between the two fixed blocks. During the insertion process, the adjusting rod is pulled, causing the limiting rod to retract into the fixed block until one side of the protective cover is in contact with one side of the base. Then, the adjusting rod is released, and under the action of the return spring, it moves horizontally, causing the limiting rod to retract into the protective cover. The above operation makes it easy to fix the protective cover to the bottom of the base, thereby protecting the surrounding surveying personnel and preventing soil and gravel flying from the drill rod during drilling and measurement from hitting the surrounding surveying personnel, thus improving its protective performance.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figures 1-5 The present invention provides the following technical solution:

[0028] Example 1: To address the problem of existing technologies lacking protective functionality during use, the following solution is disclosed. Please refer to the details below. Figure 1 , Figure 2 , Figure 5As shown, a protective soil thickness measuring device for surveying includes a base 1, support rods 2, hydraulic telescopic seats 7, and traveling wheels 16. Support rods 2 are welded to both sides of the top of the base 1, and traveling wheels 16 are fixed to both sides of the bottom of the base 1. Hydraulic telescopic seats 7 are welded to the bottom of the base 1 on one side of each traveling wheel 16. A protective cover 5 is provided at the bottom of the base 1, and limit mechanisms 15 are provided on both sides of the protective cover 5. Each limit mechanism 15 includes a fixing block 1501, which is located at the bottom of the base 1. An adjusting rod 1502 is provided inside the fixing block 1501, with one end of the adjusting rod 1502 extending to the outside of the fixing block 1501. The outer sides of the adjusting rod 1502 are... A return spring 1507 is evenly wound around an adjusting rod 1502. A baffle 1505 is fixed to one side of the adjusting rod 1502, and sliders 1503 are provided on both sides of the baffle 1505. Slide grooves 1506 are provided on the outer side of each slider 1503, and the slide grooves 1506 are all opened inside the fixing block 1501. A limit rod 1504 is fixed to one side of the baffle 1505. The sliders 1503 slide inside the slide grooves 1506. The baffle 1505 is slidably connected to the fixing block 1501 through the sliders 1503 and the slide grooves 1506. Two return springs 1507 are provided. The two return springs 1507 are symmetrically distributed, and both return springs 1507 are in a stretched state inside the fixing block 1501.

[0029] In this embodiment, when soil layer thickness needs to be measured during land surveying, the base 1 is moved to a designated position using the walking wheels 16, and the hydraulic telescopic seat 7 is activated to lift the base 1, thereby raising the walking wheels 16 away from the ground and improving the stability of the base 1 during soil layer thickness measurement. Once the base 1 is raised to a certain height, the protective cover 5 is pushed, causing it to insert between two fixed blocks 1501. During insertion, the adjusting rod 1502 is pulled, causing the baffle 1505 to move horizontally. This horizontal movement of the baffle 1505 causes the slider 1503 to slide within the groove 1506. The groove 1506 serves two purposes: firstly, it limits the movement of the baffle 1505, preventing positional shifts during movement that could affect subsequent operations; secondly, it also limits the movement of the baffle 1503. 5. The guide is used to improve the stability of its movement. While the baffle 1505 moves horizontally, it drives the limiting rod 1504 to move horizontally in sync, so that the limiting rod 1504 is retracted into the fixed block 1501. At the same time, it squeezes the return spring 1507, so that the return spring 1507 is compressed by the squeezing force until one side of the protective cover 5 is in contact with the bottom of the base 1. Then the adjusting rod 1502 is released, so that the squeezing force on the return spring 1507 is eliminated, thereby pushing the baffle 1505 to move horizontally, and then driving the limiting rod 1504 to move horizontally in sync, so that the limiting rod 1504 is inserted into the interior of the protective cover 5. Through the above operation, the protective cover 5 can be fixed to the bottom of the base 1, so as to block the mud and gravel generated by the drill rod 14 when measuring the soil layer thickness, thereby improving its protection.

[0030] Example 2: This example differs from Example 1 in that it can automatically perform measurements during use. Therefore, the following solution is disclosed. Please refer to the details below. Figure 1 , Figure 3 , Figure 4As shown, an adjustment mechanism 8 is provided on one side of a support rod 2. The adjustment mechanism 8 includes an adjustment motor 804, which is located at the top of the support rod 2. An adjustment shaft 803 is fixed to the bottom of the adjustment motor 804, and a drive gear 801 is sleeved on the outside of the adjustment shaft 803. A driven gear 802 meshes with one side of the drive gear 801, and a through hole 805 is provided inside the driven gear 802. Cleaning brushes 806 are evenly adhered inside the through hole 805. Multiple cleaning brushes 806 are provided and are arranged in a ring. The materials of the multiple cleaning brushes 806 are all... Made of rubber, another support rod 2 has a guide rod 3 fixed to one side, and a scale line 12 is provided on the outer side of the guide rod 3. A movable block 13 is sleeved on the outer side of the guide rod 3, and a moving block 11 is fixed to one side of the movable block 13. A servo motor 10 is provided at the top of the moving block 11, and a drill rod 14 is provided at the bottom of the servo motor 10. An adjustment block 9 is fixed to one side of the servo motor 10. A guide groove 6 is opened at the top of the base 1, and a guide block 4 is slidably arranged inside the guide groove 6. There are two guide blocks 4, which are symmetrically distributed, and the cross-section of both guide blocks 4 is T-shaped.

[0031] In this embodiment, when it is necessary to measure the soil layer thickness, the servo motor 10 is activated to drive the drill rod 14 to rotate, and the adjustment motor 804 is activated to drive the adjustment shaft 803 to rotate. Simultaneously, the rotation of the adjustment shaft 803 drives the adjustment block 9 to descend, which in turn drives the moving block 11 to descend synchronously. The descent of the moving block 11, in turn, drives the drill rod 14 to descend, thus performing drilling operations on the soil layer. Furthermore, the descent of the moving block 11 causes the movable block 13 to slide on the guide rod 3. The guide rod 3 has a scale line 12 that allows observation of the soil layer thickness. While the adjusting shaft 803 rotates, it also drives the drive gear 801 to rotate synchronously. Since the drive gear 801 and the driven gear 802 mesh with each other, the drive gear 801 rotates synchronously while the driven gear 802 rotates, and the driven gear 802 rotates synchronously while the cleaning brush 806 rotates. This operation facilitates the cleaning of the soil adhering to the drill rod 14 when the drill rod 14 moves upward, thereby improving its practicality.
