Description

Technical Field

[0001] The utility model belongs to the technical field of foundation pit slope measurement, and more specifically relates to a slope measuring tool. Background Art

[0002] A foundation pit is a pit excavated at the designed foundation location according to the base elevation and plan dimensions. The foundation pit slope refers to the slope formed during the excavation process. With the rapid development of high-rise buildings in cities, various requirements, such as underground parking lots, high-rise building burial depths, and civil air defense, necessitate the construction of basements within these buildings, resulting in a significant amount of foundation pit work.

[0003] When inspecting and accepting foundation pit slopes, technicians often use slope measuring rulers for measurement and inspection. However, existing slope measuring rulers can only check the slope coefficient. It is not easy to directly detect bulges on the slope surface through visual inspection, so additional tools are required for inspection, which makes it inconvenient for technicians to inspect and accept foundation pit slopes. Utility Model Content

[0004] The purpose of the utility model is to provide a slope measuring tool, which is intended to facilitate the inspection and acceptance of foundation pit slopes.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a slope measuring tool, comprising:

[0006] horizontal rod;

[0007] a measuring rod comprising a first measuring portion hinged on the horizontal rod and a second measuring portion hinged on the first measuring portion, wherein a rotation axis of the first measuring portion and a rotation axis of the second measuring portion are perpendicular to each other;

[0008] a protractor, fixedly mounted on the horizontal rod and configured to measure the angle between the horizontal rod and the first measuring portion; and

[0009] The laser emitter is fixedly arranged on the second measuring part.

[0010] In a possible implementation, the measuring rod further includes a locking pin, and when the locking pin is simultaneously inserted into the first measuring part and the second measuring part, the first measuring part and the second measuring part are fixed.

[0011] In a possible implementation, a slider is slidably provided on the horizontal rod, and a scale for displaying the slope coefficient is provided on the horizontal rod along the moving track of the slider;

[0012] The slope measuring tool further includes a connecting rod, one end of which is hinged to the first measuring part, and the other end of which is hinged to the sliding block.

[0013] In a possible implementation, a spirit level is fixedly mounted on the horizontal rod.

[0014] In one possible implementation, a lock is rotatably provided on the horizontal rod, and a connecting plate is rotatably provided on the measuring rod. A through hole is provided on the connecting plate for the lock to pass through. When the measuring rod swings to overlap with the horizontal rod, the lock passes through the connecting plate and rotates to be misaligned with the through hole, so as to fix the horizontal rod and the measuring rod.

[0015] In a possible implementation, a supporting leg is hingedly connected to the horizontal rod, and a fixing assembly for fixing the supporting leg is provided on the horizontal rod.

[0016] In one possible implementation, the fixing component includes:

[0017] an insert block, slidably disposed on the horizontal rod;

[0018] The elastic member is arranged on the horizontal rod and is used for pushing the inserting block to move toward the direction close to the supporting leg and be inserted into the supporting leg.

[0019] In a possible implementation, a first slot is provided on the support leg. When the insert block is inserted into the first slot, the support leg is folded and fits onto the horizontal rod.

[0020] In a possible implementation, a second slot is provided on the support leg, and when the insert block is inserted into the second slot, the support leg opens and extends from the horizontal rod.

[0021] In a possible implementation, one end of the leg away from the hinge axis is in a pointed cone shape.

[0022] The utility model provides a slope measurement tool that, compared with the prior art, has the following advantages: when inspecting and accepting a foundation pit slope, a horizontal rod is placed on a horizontal surface, and the measuring rod is opened and placed against the slope surface.

In addition, by turning on the laser transmitter and swinging the second measuring part along the slope surface, the laser emitted by the laser transmitter can be swung along the slope surface, and then observing whether the laser is blocked can realize the inspection of whether there is a protrusion on the slope surface. The utility model is simple to operate and the measurement results are intuitive, which provides convenience for the inspection of foundation pit slopes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] See Figures 1 to 5 The present invention provides a slope measuring tool, which includes a horizontal rod 1, a measuring rod 2, a protractor 3, and a laser transmitter 4.

[0033] Among them, see Figure 1、 Figure 2 and Figure 3 Measuring rod 2 includes a first measuring portion 21 hinged to horizontal rod 1 and a second measuring portion 22 hinged to first measuring portion 21. The rotation axis of first measuring portion 21 and second measuring portion 22 are perpendicular to each other. A protractor 3 is fixed to horizontal rod 1 and is used to measure the angle between horizontal rod 1 and first measuring portion 21. A laser emitter 4 is fixed to second measuring portion 22.

[0034] Specifically, a pointer is fixedly mounted on the first measuring section 21, and the center point of the goniometer 3 coincides with the rotation axis of the first measuring section 21. Rotating the first measuring section 21 causes the pointer to move along the scale on the goniometer 3. The angle between the first measuring section 21 and the horizontal rod 1 becomes the same as the scale indicated by the pointer, allowing a worker to directly read the angle between the first measuring section 21 and the horizontal rod 1.

[0035] When inspecting and accepting a foundation pit slope, horizontal rod 1 is placed on the ground and leveled. Then, measuring rod 2 is spread out and placed against the slope. By reading the scale on protractor 3, where the pointer is pointing, the worker can determine the angle between horizontal rod 1 and measuring rod 2. This angle is then subtracted from 180 degrees to determine the slope angle.

[0036] Since the first measuring part 21 is attached to the slope surface, and the rotation axis of the first measuring part 21 is perpendicular to the rotation axis of the second measuring part 22. Therefore, the second measuring part 22 can be attached to the slope surface and swing left and right. By turning on the laser emitter 4 and swinging the second measuring part 22 along the slope surface, the laser emitted by the laser emitter 4 can be swept along the slope surface. When a bulge appears on the slope surface, the laser light will be blocked. When a depression appears on the slope surface, it can be found by visual inspection, thereby realizing the inspection of the flatness of the slope surface. The slope measuring tool provided by the utility model can realize both the detection of the slope angle and the inspection of the bulge on the slope surface. It is easy to operate and the measurement results are intuitive, which provides convenience for the inspection of the foundation pit slope.

[0037] After the inspection, the raised areas are marked and the slope can be repaired using an excavator or manually. As for the sunken areas, they can be found by visual inspection. Shallow sunken areas do not need to be treated, while larger sunken areas can be filled and leveled.

[0038] In some embodiments, see Figure 1 、 Figure 2 and Figure 3The measuring rod 2 also includes a locking pin 23. The locking pin 23 and the second measuring portion 22 are offset relative to each other. This ensures that when the locking pin 23 is simultaneously inserted into the first and second measuring portions 21, 22, the first and second measuring portions 21, 22 are fixedly connected. A connecting rope 231 is fixedly connected between the locking pin 23 and the second measuring portion 22 to prevent the locking pin 23 from being lost when it is removed.

[0039] When the measuring rod 2 is folded and stored, the locking pin 23 is simultaneously inserted into the first measuring portion 21 and the second measuring portion 22. At this time, the first measuring portion 21 and the second measuring portion 22 are coaxial, so that the measuring rod 2 can be better fitted on the horizontal rod 1, reducing space occupation and making it more convenient for staff to carry and take it.

[0040] In some embodiments, a slider 11 is slidably mounted on the horizontal rod 1. A scale for displaying the slope coefficient is provided on the horizontal rod 1 along the movement trajectory of the slider 11. The slope measurement tool further includes a connecting rod 5, one end of which is hinged to the first measuring portion 21 and the other end of which is hinged to the slider 11.

[0041] When the staff rotates the measuring rod 2, the connecting rod 5 is rotated, and the connecting rod 5 drives the slider 11 to slide on the horizontal rod 1. The different angles between the measuring rod 2 and the horizontal rod 1 correspond to different positions of the slider 11 on the horizontal rod 1. This allows the staff to not only determine the angle of the slope, but also the slope coefficient corresponding to the slope angle. This simplifies the slope coefficient detection process, makes the measurement results more intuitive, and provides convenience for the inspection of foundation pit slopes.

[0042] In some embodiments, see Figure 1 and Figure 2 , a level 12 is fixedly provided on the horizontal rod 1. By observing the level 12, it is convenient for the staff to level the horizontal rod 1.

[0043] In some embodiments, see Figure 1 、 Figure 2 and Figure 4 A lock buckle 61 is rotatably provided on the horizontal rod 1, and a connecting plate 62 is rotatably provided on the measuring rod 2. A through hole 621 is provided on the connecting plate 62 for the lock buckle 61 to pass through. When the measuring rod 2 swings to overlap with the horizontal rod 1, the lock buckle 61 passes through the connecting plate 62 and rotates to be misaligned with the through hole 621, so that the horizontal rod 1 and the measuring rod 2 are fixed.

[0044] When the measuring rod 2 is to be carried or stored, the locking pin 23 is first inserted into both the first measuring portion 21 and the second measuring portion 22, so that the measuring rod 2 is straight. Then, the measuring rod 2 is rotated until it overlaps the horizontal rod 1. At this point, the ends of the horizontal rod 1 and the measuring rod 2 are flush with each other.

[0045] The connecting plate 62 is rotated so that the lock buckle 61 passes through the through hole 621, and then the lock buckle 61 is rotated so that the lock buckle 61 and the through hole 621 are displaced from each other. At this time, the connecting plate 62 cannot rotate under the action of the lock buckle 61, and the lock buckle 61 presses the connecting plate 62 against the horizontal rod 1, so that the connecting plate 62 fits on the horizontal rod 1, thereby fixing the horizontal rod 1 and the measuring rod 2, preventing relative rotation between the horizontal rod 1 and the measuring rod 2, and ensuring the security when the staff carries and picks up the measuring rod.

[0046] In some embodiments, see Figure 3 、 Figure 4 and Figure 5 The horizontal rod 1 is hinged with a support leg 7, and the horizontal rod 1 is provided with a fixing component for fixing the support leg 7.

[0047] When measuring, the legs 7 are extended from the horizontal rod 1 and secured with the fixing assembly to maintain stability. Inserting the legs 7 into the ground further secures the horizontal rod 1, making it less likely to be disturbed when rotating the measuring rod 2, thereby improving measurement accuracy. When transporting or storing, the legs 7 are rotated until they fit snugly against the horizontal rod 1, then secured with the fixing assembly to maintain stability and prevent injuries to personnel from being pulled out of the horizontal rod 1.

[0048] In some embodiments, see Figure 6 The fixing assembly includes an insert block 81 and an elastic member 82. The insert block 81 is slidably arranged on the horizontal rod 1. The elastic member 82 is arranged on the horizontal rod 1, and is used to push the insert block 81 to move toward the support leg 7 and be plugged into the support leg 7. Specifically, a push plate 811 is fixedly provided on the insert block 81, and the push plate 811 extends from the horizontal rod 1, so that the staff can drive the insert block 81 to move through the push plate 811, thereby realizing the connection and separation between the insert block 81 and the support leg 7. The elastic member 82 is a spring, and the two ends of the spring are fixedly connected to the horizontal rod 1 and the insert block 81 respectively. The spring is always in a compressed state, and the elastic force of the spring acts on the insert block 81, so that the insert block 81 extends from the horizontal rod 1 and is plugged into the support leg 7.

[0049] As an alternative embodiment, the elastic member 82 can also be an elastic object such as an elastic rope, an elastic block, etc., and can exert elastic force on the plug block 81 so that the plug block 81 extends from the horizontal rod 1 and is plugged into the support leg 7.

[0050] In some embodiments, see Figure 6 The leg 7 is provided with a first slot 71. When the insert block 81 is inserted into the first slot 71, the leg 7 is folded and fits on the horizontal rod 1. The horizontal rod 1 is provided with a receiving groove for accommodating the leg 7. When the leg 7 is folded and stored on the horizontal rod 1, the leg 7 is completely retracted into the horizontal rod 1. The surface of the leg 7 is flush with the surface of the horizontal rod 1, thereby reducing space occupation.

[0051] When the device is ready for transport or storage, the insert block 81 is pulled out of the leg 7. The leg 7 is then rotated toward the horizontal bar 1, folding and storing it in the receiving slot. The insert block 81 is then released, and the elastic member 82 engages the first slot 71, securing the leg 7 securely and preventing it from being pulled out of the horizontal bar 1 due to external disturbances.

[0052] In some embodiments, see Figure 6 A second slot 72 is provided on the support leg 7 . When the insert block 81 is inserted into the second slot 72 , the support leg 7 opens and extends from the horizontal rod 1 .

[0053] When measuring, the operator pulls the insert 81 to remove it from the leg 7. The leg 7 is then rotated so that the leg 7 and the horizontal rod 1 remain perpendicular to each other. At this point, the insert 81 is released. The elastic member 82 allows the insert 81 to extend and engage the leg 7, securing the leg 7 firmly. By inserting the leg 7 into the ground, the horizontal rod 1 is firmly fixed, making it more stable during use and less prone to shaking or tilting, thereby ensuring accurate measurements.

[0054] In some embodiments, see Figure 3 The end of the support leg 7 away from the hinge axis is in a pointed cone shape. The pointed cone-shaped support leg 7 is more labor-saving when inserted into the ground, making it more convenient for the staff to operate.

[0055] In summary, the slope measuring tool provided by the present invention is different from the prior art. When inspecting and accepting the foundation pit slope, the horizontal rod 1 is placed on the horizontal ground, and the measuring rod 2 is opened and attached to the slope surface. At this time, the angle between the horizontal rod 1 and the measuring rod 2 can be obtained by the protractor 3, thereby obtaining the angle of the slope. In addition, by turning on the laser emitter 4 and swinging the second measuring part 22 along the slope surface, the laser emitted by the laser emitter 4 can be swung along the slope surface, and then observing whether the laser is blocked can realize the inspection of whether there is a bulge on the slope surface. The operation is simple, the measurement results are intuitive, and it provides convenience for the inspection of the foundation pit slope.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
