Description

Technical Field

[0001] This utility model belongs to the field of slope ratio measurement technology, specifically a slope ratio measurement device for foundation pit slopes. Background Technology

[0002] A foundation pit is an earthen pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. In foundation pit engineering, slope ratio measurement is a core technical link to ensure construction safety and control project quality. In order to avoid landslides caused by slope deformation, a slope ratio measuring device is needed to measure the slope ratio of the foundation pit during the construction process to ensure that the slope ratio is within a safe value.

[0003] The existing slope meter includes: a level tube, an angle scale, a base, and a pointer mechanism. Check if the bubble level is centered, return the pointer to zero, place the slope meter reference surface tightly, read the scale value indicated by the pointer, and then manually fill in the measurement form to complete the measurement of the slope ratio.

[0004] However, existing devices still have some problems. The level tubes are mostly installed in an open manner, which makes them prone to collision with the support piles during foundation pit operations, resulting in damage to the level tubes and pointers, which in turn reduces the practicality of the measuring device. Therefore, a slope ratio measuring device for foundation pit slopes is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems with existing equipment, this utility model proposes a slope ratio measuring device for foundation pit slopes.

[0006] The technical solution adopted by this utility model to solve its technical problem is a slope ratio measuring device for foundation pit slopes, comprising: a measuring device body, an angle scale dial fixedly connected to the measuring device body, a pointer installed on the measuring device body, a gear adjusting buckle rotatably connected to the measuring device body, a level tube rotatably connected to the measuring device body, the gear adjusting buckle and the level tube meshing with each other, a connecting rod rotatably connected inside the measuring device body, a bolt threaded inside the connecting rod, a sliding groove formed on the surface of the measuring device body, a connecting groove formed inside the sliding groove, a baffle hinged at the connection between the connecting groove and the sliding groove, an elastic piece fixedly connected to one side of the baffle, one end of the elastic piece fixedly connected to the inner wall of the connecting groove, a transparent protective plate rotatably connected to the connecting rod, a slider fixedly connected to one side of the transparent protective plate, the slider slidably connected inside the sliding groove, the connecting rod and the bolt can fix one side of the transparent protective plate, and thus, in cooperation with the rubber pad and the connecting groove, the position of the transparent protective plate can be fixed.

[0007] Preferably, a rod is fixedly connected to one side of the slider, and a rubber ring is fixedly connected to the outside of the rod. The rod and the rubber ring are movably connected inside the connecting groove. The transparent protective plate is located outside the angle scale and the level tube. The position of the baffle is fixed by the elasticity of the elastic sheet. After the rubber ring enters the connecting groove, it cooperates with the connecting rod and the bolt to fix the transparent protective plate to the outside of the angle scale and the level tube.

[0008] Preferably, a support groove is provided at the bottom of the measuring device body, a first spring is fixedly connected to the inner wall of the measuring device body, and a rubber positioning pad is fixedly connected inside the measuring device body. When the rubber positioning pad is opposite to the positioning groove, the rubber positioning pad can be pushed into the positioning groove by the elastic force of the first spring itself, thereby fixing its position.

[0009] Preferably, a second spring is fixedly connected to the inner wall of the rubber positioning pad, a T-shaped connecting frame is slidably connected inside the support groove, an adjusting frame is fixedly connected to one side of the T-shaped connecting frame, the adjusting frame is slidably connected inside the measuring device body, and the T-shaped connecting frame is slidably connected inside the support groove, so that the adjusting frame can be supported and its height adjusted through the support groove.

[0010] Preferably, one side of the adjusting frame is fixedly connected to one end of the first spring, and the adjusting frame is provided with two sets of positioning grooves. Anti-slip pads are fixedly connected to the inner walls of the two sets of positioning grooves. The rubber positioning pads are movably connected to the two sets of positioning grooves. The anti-slip pads can increase the friction with the rubber positioning pads, thereby improving the fixing strength of the adjusting frame.

[0011] Preferably, a positioning rod is rotatably connected to the bottom of the measuring device body, and a sliding rod is slidably connected inside the positioning rod. The sliding rod is rotatably connected inside the adjusting frame. The positioning rod is driven by the sliding rod, which can change the tilt angle of the positioning rod, so that the positioning rod is in a vertical state when the measuring device is in use, and the device can be fixed on the slope, making the measuring device more convenient to use.

[0012] The advantages of this utility model are as follows: the elasticity of the elastic sheet fixes the position of the baffle, so that after the rubber ring enters the connecting groove, it cooperates with the connecting rod and bolts to fix the transparent protective plate on the outside of the angle scale and the level tube. When used for wave ratio measurement, the transparent protective plate can withstand the impact force of debris falling from the inner wall of the pit on the level tube and the angle scale, which can prevent the level tube and the angle scale from being damaged during use, thereby avoiding affecting the utilization rate of the measuring device and improving the practicality and utilization rate of the measuring device.

[0013] This utility model involves pulling the adjustment frame, which drives the sliding rod to move synchronously. This changes the exposed length of the sliding rod while simultaneously rotating the positioning rod, ensuring it is in a vertical position. The positioning rod is then fixed in this vertical position through the cooperation of the rubber positioning pad, the second spring, the positioning groove, and the anti-slip pad. This allows the positioning rod to be used to fix the measuring device on the slope when measuring the slope ratio of soft foundation pits. Compared to traditional supports, this method avoids settlement of the measuring device, improves its stability during use, and ultimately enhances the accuracy of the measurement data.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 As shown, a slope ratio measuring device for a foundation pit includes: a measuring device body 1, an angle scale dial 2 fixedly connected to the measuring device body 1, a pointer 3 mounted on the measuring device body 1, a gear adjusting buckle 4 rotatably connected to the measuring device body 1, a level tube 5 rotatably connected to the measuring device body 1, the gear adjusting buckle 4 and the level tube 5 meshing together, a connecting rod 6 rotatably connected inside the measuring device body 1, a bolt 7 threadedly connected inside the connecting rod 6, a groove 8 formed on the surface of the measuring device body 1, a connecting groove 9 formed inside the groove 8, and the connecting groove 9 connecting to... A baffle 10 is hinged at the connection of the slide groove 8. An elastic piece 11 is fixedly connected to one side of the baffle 10. One end of the elastic piece 11 is fixedly connected to the inner wall of the connecting groove 9. A transparent protective plate 12 is rotatably connected to the connecting rod 6. A slider 13 is fixedly connected to one side of the transparent protective plate 12. The slider 13 is slidably connected inside the slide groove 8. An insertion rod 14 is fixedly connected to one side of the slider 13. A rubber ring 15 is fixedly connected to the outside of the insertion rod 14. The insertion rod 14 and the rubber ring 15 are movably connected inside the connecting groove 9. The transparent protective plate 12 is located outside the angle scale 2 and the level tube 5.

[0023] An excavation pit is a pit dug according to the foundation elevation and foundation plane dimensions at the foundation design location. In excavation pit engineering, a slope ratio measuring device is needed to measure the slope ratio of the excavation pit to ensure it is within a safe range. In actual use, a transparent protective plate 12 is fitted onto the connecting rod 6, and then bolts 7 are screwed into the connecting rod 6. The transparent protective plate 12 is fixed to the measuring device body 1 by the cooperation of the measuring device body 1 and bolts 7. Then, the measuring device body 1 is rotated around the connecting rod 6, causing the slider 13 to slide along the groove 8, thus inserting... The rod 14 and rubber ring 15 are pushed into the connecting groove 9. When the rubber ring 15 enters, it applies pressure to the baffle 10 and the elastic plate 11. After the rubber ring 15 is fully inside the connecting groove 9, the elastic plate 11 restores the baffle 10 to its original position, blocking the position of the rubber ring 15, thus fixing the rubber ring 15 inside the connecting groove 9. It can then cooperate with the connecting rod 6 and bolt 7 to fix the transparent protective plate 12 to the outside of the angle scale 2 and the level tube 5. When the measuring device body 1 is in use, the transparent protective plate 12 can withstand debris falling from the inner wall of the pit. The impact force exerted by the object on the level tube 5 and the angle scale 2 can prevent damage to the level tube 5 and the angle scale 2 during use, thereby avoiding affecting the utilization rate of the measuring device and improving its practicality and utilization rate. After fixing the transparent protective plate 12 to the outside of the angle scale 2, one side of the measuring device body 1 is then placed against the slope of the foundation pit. The gear adjustment buckle 4 is rotated to drive the level tube 5 to rotate synchronously. The position of the bubble in the level tube 5 is observed to ensure that the level tube 5 is in a horizontal state. Since the pointer 3 is a gravity pendulum type, it is adjusted accordingly. After completion, the slope ratio of the foundation pit can be measured and read by pointing the pointer 3 to the angle scale 2. After the measuring device is used, the transparent protective plate 12 is rotated in the opposite direction along the slide 8, and the rubber ring 15 is moved out of the interior of the connecting groove 9 by the slider 13. After the rubber ring 15 is completely moved out of the slide 8, the bolt 7 is rotated in the opposite direction and screwed out of the interior of the connecting rod 6, so as to release the fixation of the transparent protective plate 12, which makes it easy to remove the transparent protective plate 12 for cleaning and avoids dust on the surface of the transparent protective plate 12 from affecting the reading of measurement data.

[0024] Please see Figure 1-5As shown, a support groove 16 is provided at the bottom of the measuring device body 1. A first spring 17 is fixedly connected to the inner wall of the measuring device body 1. A rubber positioning pad 18 is fixedly connected inside the measuring device body 1. A second spring 19 is fixedly connected to the inner wall of the rubber positioning pad 18. A T-shaped connecting frame 20 is slidably connected inside the support groove 16. An adjusting frame 21 is fixedly connected to one side of the T-shaped connecting frame 20. The adjusting frame 21 is slidably connected inside the measuring device body 1. One side of the adjusting frame 21 is fixedly connected to one end of the first spring 17. Two sets of positioning grooves 22 are provided on the adjusting frame 21. Anti-slip pads are fixedly connected to the inner walls of both sets of positioning grooves 22. The rubber positioning pad 18 is movably connected to both sets of positioning grooves 22. A positioning rod 23 is rotatably connected to the bottom of the measuring device body 1. A sliding rod 24 is slidably connected inside the positioning rod 23. The sliding rod 24 is rotatably connected inside the adjusting frame 21.

[0025] When measuring the slope ratio of a soft foundation pit slope, the adjusting frame 21 is pulled outward, causing the sliding rod 24 to rotate. Simultaneously, the sliding rod 24 and the adjusting frame 21 move laterally, changing the exposed length of the sliding rod 24. This causes the positioning rod 23 to rotate synchronously, moving one end of the positioning rod 23 out of the bottom of the measuring device body 1. When the positioning rod 23 is in a vertical position, the rubber positioning pad 18 is opposite the inner positioning groove 22. The second spring 19 pushes the rubber positioning pad 18 into the positioning groove 22, making the rubber positioning pad 18 fit against the anti-slip pad inside the positioning groove 22, thus fixing the position of the adjusting frame 21. This fixes the positioning rod 23 in a vertical position. When using the measuring device body 1, multiple sets of positioning rods 23 are inserted into the soft foundation pit slope, ensuring one side of the measuring device body 1 is completely in contact with the slope. This allows for the measurement of the slope ratio of a soft foundation pit slope. When reading and recording data, the measuring device body 1 is released, making data reading more convenient. Compared with traditional supports, using multiple sets of positioning rods 23 to fix the measuring device body 1 on the soft slope of the foundation pit can prevent the measuring device body 1 from settling during the measurement process, thereby reducing the displacement of the measuring device body 1 during measurement, improving the stability of the measuring device during use, and thus improving the accuracy of the measurement data. After the measurement is completed, the adjusting frame 21 is pushed inward, cooperating with the stretched first spring 17, which drives the adjusting frame 21 and the sliding rod 24 to move, so that the sliding rod 24 enters the interior of the positioning rod 23, thereby driving the positioning rod 23 to rotate, so that the positioning rod 23 is retracted to the bottom of the measuring device body 1. This prevents the positioning rod 23 from causing injury to the user when the measuring device is not in use, thereby improving the safety of the measuring device.

[0026] Working principle: The transparent protective plate 12 is fitted onto the connecting rod 6, and then the bolt 7 is screwed into the interior of the connecting rod 6. The transparent protective plate 12 is fixed to the measuring device body 1 by the cooperation of the measuring device body 1 and the bolt 7. Then, the measuring device body 1 is rotated around the connecting rod 6, so that the slider 13 slides along the slide groove 8, pushing the insertion rod 14 and the rubber ring 15 into the interior of the connecting groove 9. The elasticity of the elastic piece 11 restores the baffle 10 to its original position, blocking the position of the rubber ring 15, thereby fixing the rubber ring 15 inside the connecting groove 9. In cooperation with the connecting rod 6 and the bolt 7, the transparent protective plate 12 is fixed to the outside of the angle scale 2 and the level tube 5. When the measuring device body 1 is in use, it can withstand the impact of debris falling from the inner wall of the pit on the level tube 5 and the angle scale 2, avoiding damage to the level tube 5 and the angle scale 2 during use. Pulling the adjusting frame 21 outward causes the sliding rod 24 to rotate, and at the same time, the sliding rod 24 and the adjusting frame are rotated. 21 moves horizontally synchronously, thereby changing the exposed length of the slide rod 24, which in turn drives the positioning rod 23 to rotate synchronously, causing one end of the positioning rod 23 to move out of the bottom of the measuring device body 1. When the positioning rod 23 is in a vertical state, the rubber positioning pad 18 is opposite to the inner positioning groove 22. The second spring 19 pushes the rubber positioning pad 18 into the positioning groove 22, so that the rubber positioning pad 18 is in contact with the anti-slip pad inside the positioning groove 22, thereby fixing the position of the adjusting frame 21 and fixing the positioning rod 23 in a vertical state. When using the measuring device body 1, multiple sets of positioning rods 23 are inserted into the soft foundation pit slope. Then, one side of the measuring device body 1 is placed against the foundation pit slope. The gear adjusting buckle 4 is rotated to drive the level tube 5 to rotate synchronously. The position of the bubble in the level tube 5 is observed, so that the level tube 5 is in a horizontal state. The slope ratio of the foundation pit slope can be measured and read by the pointer 3 indicating the value of the angle scale 2, thereby completing the measurement of the wave ratio.
