[0007] Preferably, both the top seat and the base are provided with a rope pressing mechanism. The rope pressing mechanism is provided with a rotatably connected drive rod. One end of the drive rod is connected to a rotating motor. An extension rod is connected to the outer wall of the drive rod. A pressing rod is installed at the end of the extension rod away from the drive rod.

[0008] Preferably, the two leveling rollers are respectively disposed at both ends of the leveling component, and a plurality of leveling plates are disposed at the bottom of the leveling component between the two leveling rollers, with the leveling plates extending along the axial direction of the leveling rollers.

[0009] Preferably, a groove is provided at the bottom of the leveling component corresponding to the position of the leveling plate. A spring is connected to the top inner wall of the groove. A slider is installed at the bottom end of the spring and slides in contact with the inner wall of the groove. A sliding rod is installed at the bottom end of the slider. The leveling plate is fixed to one end of the sliding rod.

[0010] Preferably, the bottom end of the slide is detachably connected to a mounting plate, the mounting plate has a through hole at the position corresponding to the slide rod, and an electromagnetic block is fixed on the top of the mounting plate. When the electromagnetic block is energized, it magnetically attracts the slider.

[0011] Preferably, an even number of the plurality of plate plates are provided, and the plurality of plate plates are provided with front plates and rear plates that are alternately distributed at intervals, and the electromagnetic blocks corresponding to the front plates and rear plates alternately perform power-on and power-off operations.

[0012] Preferably, a notch three is provided on the leveling component at the position corresponding to the pull rope, a pull rod is installed in the notch three, and a tension sensor is connected between the pull rod and the pull rope. The tension sensor is used to monitor the magnitude of the tension applied by the pull rope to the pull rod in real time.

[0013] Preferably, a pressure sensor is installed on the pressure rod at a position corresponding to the limiting rope. The pressure sensor is used to monitor the pressure at the contact position between the limiting rope and the pressure rod in real time. A pressure sensor is connected between the spring and the slider. The pressure sensor is used to monitor the squeezing force between the spring and the slider in real time.

[0014] Preferably, the monitoring values ​​from the tension sensor, pressure sensor one, and pressure sensor two are uploaded to the processor, and an evaluation coefficient is calculated through comprehensive analysis. The calculation logic is as follows:

[0015] Step 1: The tension sensor acquires monitoring values ​​in real time. The pressure sensor acquires monitoring values ​​in real time. Pressure sensor 2 acquires monitoring values ​​in real time. ;

[0016] Step 2: Calculate the evaluation coefficient , ;

[0017] In the formula, , , The weighting factor is determined through experimental testing or engineering experience, based on the importance of each sensor's data to the overall operating status of the equipment under different working scenarios; where... This is a reference value for the tension sensor readings under ideal conditions. This is a reference value for the pressure sensor's monitored value under ideal conditions. The reference value for the pressure sensor 2's monitored value under the set ideal condition;

[0018] Step 3: Compare the evaluation coefficient with the reference coefficient. If the evaluation coefficient is greater than the reference coefficient, it means that the leveling part is excessively warped, and the staff should be reminded in time to manually repair and level it.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. In this invention, the leveling component is moved along the slope direction by the limiting rope, while the leveling component is limited in the direction perpendicular to the slope. This avoids the leveling component from lifting up due to hard protrusions on the slope, thus preventing it from effectively leveling. It is also convenient to adjust the limiting rope to match the slope inclination direction to limit the leveling component.

[0025] 2. In this invention, the tilt angle and descent distance of the limiting rope can be adjusted by pressing down on both ends of the limiting rope, thereby making the leveling component adapt to the corresponding slope and ensuring effective leveling operation of the leveling component during movement; thus, the overall design improves the leveling operation effect as well as the portability and applicability of the use.

[0026] 3. In this invention, the slope is pressed downward by the gap between the front plate and the rear plate, which can press and flatten the harder protruding parts. The flattening rollers set at the front and rear can improve the flattening effect and prevent the flattening parts from lifting due to the harder protruding parts, thus affecting the flattening operation.

[0027] 4. In this invention, data is collected from multiple dimensions such as the traction, limiting and interaction between the working parts and the slope by sensors at different locations. Compared with a single sensor, this greatly enriches the sources of evaluation data, making the evaluation results more consistent with the actual working state of the equipment. When the leveling parts are raised too much and cannot be completely leveled, the staff are promptly reminded. Attached Figure Description

[0039] Example 1: Refer to Figures 1-10 A slope leveling device for building foundation pit construction includes a leveling component 1, with two leveling rollers 10 at its bottom, a top seat 2, and a base 3. Two limiting ropes 5 are connected between the top seat 2 and the base 3. Slip rings 9 are installed on both sides of the leveling component 1, slidingly contacting the limiting ropes 5. The housings of the slip rings 9 are detachable for easy engagement or disengagement with the limiting ropes 5. A winch 6 is located below the top seat 2, with a pull rope 7 wound around it. One end of the pull rope 7 is fixedly connected to the leveling component 1. The bottom of the top seat 2... Both sides are equipped with brackets 8. It should be noted that the winch 6 contains a frame and a rotating roller 601. A pull rope 7 is wound around the roller 601, and one end of the roller 601 is connected to a drive motor to move the leveling component 1 by winding the pull rope 7. Further, it should be noted that the top seat 2 has a connecting groove 201 corresponding to the position of the limiting rope 5. A connecting rod 202 is installed in the connecting groove 201, and the end of the limiting rope 5 near the top seat 2 is bound and fixed to the connecting rod 202. The base 3 and the limiting rope... A connecting groove 301 is provided at the corresponding position 5, and a connecting rod 302 is installed in the connecting groove 301. The end of the limiting rope 5 near the base 3 is tied and fixed to the connecting rod 302. During use, the leveling component 1 is placed on the slope surface of the slope 4, the top seat 2 is fixed at the top position of the slope 4, and the base 3 is fixed at the bottom position of the slope 4. After the two limiting ropes 5 are fixed, the leveling component 1 moves along the extension direction of the limiting ropes 5. On the one hand, the limiting ropes 5 limit the leveling component 1 to move along the slope 4. The slope direction is moved, while the leveling component 1 is limited in the direction perpendicular to the slope to prevent the leveling component 1 from tilting up due to hard protrusions on the slope, thus failing to achieve effective leveling. On the other hand, the leveling component 1 is limited by the limiting rope 5, which facilitates the replacement or movement of the overall equipment position. Moreover, the limiting rope 5 can be easily adjusted to adapt to the inclination direction of the slope to limit the leveling component 1 relative to the support guide rail structure. Thus, the overall design improves the effectiveness and leveling effect of the leveling operation, and enhances the convenience and applicability of the equipment.

[0040] In this invention, both the top seat 2 and the base 3 are equipped with rope pressing mechanisms. Each rope pressing mechanism has a rotatably connected drive rod 11. One end of the drive rod 11 is connected to a rotating motor. An extension rod 12 is connected to the outer wall of the drive rod 11. A pressure rod 13 is installed at the end of the extension rod 12 away from the drive rod 11. The drive rod 11 and the pressure rod 13 are perpendicular to the limiting rope 5. The pressure rod 13 is located on the side of the limiting rope 5 away from the slope 4. It should be noted that a notch 203 is provided on the top seat 2 at a position corresponding to the rope pressing mechanism, and the drive rod 11 is rotatably positioned within the notch 203. A second notch 303 is provided on the base 3 at a position corresponding to the rope pressing mechanism, allowing the drive rod 11 to rotate. Set in notch 2 303; during installation, after the two ends of the limiting rope 5 are tied and fixed to the top seat 2 and the base 3 respectively, the limiting rope 5 can be pressed down by rotating the pressure rod 13 on the top seat 2 and the base 3 by a certain angle. On the one hand, the tension of the limiting rope 5 during use is increased to ensure the stability and effectiveness of limiting the leveling part 1. On the other hand, by pressing down the two ends of the limiting rope 5 respectively, the tilt angle and descent distance of the limiting rope 5 can be adjusted, so as to make the leveling part 1 adapt to the corresponding slope and ensure the effective leveling operation of the leveling part 1 during the movement. Thus, the leveling operation effect, as well as the portability and applicability of the use are improved through the overall setting.

[0041] In this invention, two leveling rollers 10 are respectively disposed at both ends of the leveling component 1, that is, the two leveling rollers 10 are distributed in the front and rear positions in the moving direction of the leveling component 1. Multiple leveling plates 14 are disposed at the bottom of the leveling component 1 between the two leveling rollers 10. The leveling plates 14 extend along the axial direction of the leveling rollers 10. A groove 103 is formed at the bottom of the leveling component 1 at a position corresponding to the leveling plate 14. A spring 15 is connected to the top inner wall of the groove 103. A slider 16 is installed at the bottom end of the spring 15, sliding in contact with the inner wall of the groove 103. A sliding rod 17 is installed at the bottom end of the slider 16. One end of the leveling plate 14 is fixed to the sliding rod 17. It should be noted that the slider 16 and the sliding rod 17 are... The cross-section of the groove 103 is set into a rectangular structure. The bottom end of the groove 103 is detachably connected to the mounting plate 18. The mounting plate 18 has a through hole at the position corresponding to the slide rod 17. An electromagnetic block 19 is fixed on the top of the mounting plate 18. When the electromagnetic block 19 is energized, it magnetically attracts the slider 16. Thus, when the electromagnetic block 19 is energized, it magnetically attracts the slider 16, thereby pressing the entire plate 14 down the slope. When the electromagnetic block 19 is de-energized, the entire plate 14 is lifted off the slope by the elastic force of the spring 15, so as to realize the reciprocating motion of the entire plate 14 to squeeze the slope, thereby squeezing and leveling the harder protruding parts on the slope, thereby improving the leveling effect.

[0042] In this invention, an even number of multiple flat plates 14 are provided, and the multiple flat plates 14 are provided with front plates 141 and rear plates 142 that are alternately distributed at intervals. The electromagnetic blocks 19 corresponding to the front plates 141 and rear plates 142 alternately perform power-on and power-off operations.

[0043] It should be noted that: such as Figure 8 In the first state of the flat plate 14 shown, the front plate 141 and the rear plate 142 are alternately distributed. At this time, the electromagnetic block 19 corresponding to the front plate 141 is energized and presses down on the slope, while the rear plate 142 is de-energized and moves away from the slope. Figure 8 The dashed box in the image represents the area that the front panel 141 will move to cover when it is pressed down.

[0044] After the front plate 141 and rear plate 142 move a short distance with the flat plate 14, as Figure 9 The flat plate 14 shown is in state two. Figure 9 The dashed box in the image represents the area already covered by the front panel 141; at this point, the power to the electromagnetic block 19 corresponding to the front panel 141 is turned off.

[0045] Then, after continuing to move a short distance, that is, after a short period of time during the continuous movement of leveling component 1, such as... Figure 10 In state three of the flat plate 14 shown, the rear plate 142 reaches the tail end of the area covered by the corresponding front plate 141. At this time, the electromagnetic block 19 corresponding to the rear plate 142 is energized, causing the rear plate 142 to press down the slope and move the rear plate 142 to overlap with the previous covered area.

[0046] By using the front plate 141 and rear plate 142, which are spaced relatively close together, the front plate 141 and rear plate 142 can fully contact and level the slope in the direction of movement. On the other hand, the gap between the front plate 141 and rear plate 142 can press the slope downwards, thereby pressing and leveling the harder protruding parts. This, combined with the leveling rollers 10 arranged at the front and rear, improves the leveling effect and prevents the leveling part 1 from lifting up due to the harder protruding parts, thus affecting the leveling operation.

[0047] Example 2: Refer to Figures 1-10A slope leveling device for building foundation pit construction, based on embodiment 1, has a notch 3 101 on the leveling component 1 at a position corresponding to the pull rope 7. A pull rod 102 is installed in the notch 3 101, and a tension sensor is connected between the pull rod 102 and the pull rope 7. The tension sensor is used to monitor the magnitude of the tension applied by the pull rope 7 to the pull rod 102 in real time. When the leveling component 1 tilts up, the value monitored by the tension sensor will change abnormally. A pressure sensor 1 is installed on the pressure rod 13 at a position corresponding to the limit rope 5. The pressure sensor 1 is used to monitor the limit in real time. The pressure at the contact point between rope 5 and pressure rod 13 is such that when there is a hard protrusion on the slope 4 that the leveling part 1 is lifted, the limiting ropes 5 on both sides will be stretched upward, thus increasing the pressure between the limiting ropes 5 and pressure rod 13. A pressure sensor 2 is connected between spring 15 and slider 16. The pressure sensor 2 is used to monitor the squeezing force between spring 15 and slider 16 in real time. When the leveling part 1 is lifted, the leveling plate 14 corresponding to electromagnetic block 19 will move downward under the power-on state, thus reducing the squeezing force between spring 15 and slider 16.

[0048] In this invention, the monitoring values ​​from the tension sensor, pressure sensor one, and pressure sensor two are uploaded to the processor, and an evaluation coefficient is calculated through comprehensive analysis. The calculation logic is as follows:

[0049] Step 1: The tension sensor acquires monitoring values ​​in real time. The pressure sensor acquires monitoring values ​​in real time. Pressure sensor 2 acquires monitoring values ​​in real time. ;

[0050] Step 2: Calculate the evaluation coefficient , ;

[0051] In the formula, , , The weighting factor is determined through experimental testing or engineering experience, based on the importance of each sensor's data to the overall operating status of the equipment under different working scenarios; where... This is a reference value for the tension sensor readings under ideal conditions. This is a reference value for the pressure sensor's monitored value under ideal conditions. The reference value for the pressure sensor 2's monitored value under the set ideal condition;

[0052] Step 3: Compare the evaluation coefficient with the reference coefficient. If the evaluation coefficient is greater than the reference coefficient, it indicates that the leveling component 1 may be excessively raised and not completely flattened or leveled, requiring timely reminders for manual repair and leveling. If the evaluation coefficient is less than the reference coefficient, it indicates normal operation. Data is collected from multiple dimensions, including equipment traction, limit switches, and interaction between the working components and the slope, using sensors at different locations. Compared to a single sensor, this significantly enriches the data sources for evaluation, making the evaluation results more consistent with the actual working state of the equipment. By comparing and analyzing this data, problems encountered by the equipment can be more accurately identified, avoiding misjudgments caused by single sensor malfunctions or local interference, and significantly improving evaluation accuracy. The comprehensive coefficient integrates this information from different aspects, enabling accurate evaluation of the equipment's condition under various complex slope conditions.

[0053] In this invention, the inclination angle of the slope is determined in advance. And upload to the processor , and Configure;

[0054] In the formula, The reference values ​​set for a horizontal plane can be determined experimentally. To set the coefficients, which can be derived experimentally or theoretically based on factors such as the weight of the equipment itself and friction;

[0055] In the formula, The reference values ​​set for a horizontal plane can be determined experimentally. To set the coefficients, which can be derived experimentally or theoretically based on factors such as the weight of the equipment itself and friction;

[0056] In the formula, The reference values ​​set for a horizontal plane can be determined experimentally. To set the coefficients, they can be derived through experiments or theories based on factors such as the equipment's own weight and friction. Incorporating the slope angle into the evaluation coefficient calculation makes the evaluation results more closely reflect the actual state of the equipment under actual working conditions. By combining the slope angle calculation reference value, it is possible to more accurately determine whether the tension value is within the normal range, thereby making a precise evaluation of the working state of the equipment's traction system and comprehensively evaluating the equipment's attitude stability under different slope angles.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
