Description

Technical Field

[0001] This utility model relates to the field of slope detection technology, specifically to an adjustable-height highway slope detection device. Background Technology

[0002] In the field of highway construction and maintenance, slope detection is a crucial step in ensuring road safety and quality. Traditional slope detection devices are typically placed directly on the ground for measurement. However, while these devices are generally designed to be small and easy to carry and operate, this compact design actually leads to inconvenience in observation during practical operation.

[0003] Because of the small size of the device, operators often need to squat or bend over to observe measurement data and adjust the device. Frequent squatting and standing up consumes a lot of time and energy, reducing overall work efficiency. This inconvenience is particularly noticeable when it is necessary to continuously measure the slope of multiple road sections. Therefore, it is necessary to design an adjustable-height highway slope detection device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-height highway slope detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-height highway slope detection device, including a support member, a first slider slidably connected to the support member, a slidable detection member provided on one side of the first slider, the detection member being locked by fasteners, and a locking component provided on the other side of the first slider to lock the position of the first slider.

[0006] Preferably, the support includes baffles and columns. Two sets of baffles are arranged in parallel, and four sets of columns are welded between the two sets of baffles. The four sets of columns correspond to the four corners of the baffles, and all four sets of columns penetrate the first slider and are slidably connected to it.

[0007] Preferably, the locking assembly includes a limiting plate, a first bolt, and a limiting block. The limiting plate is installed in the cavity on one side of the first slider. The limiting plate is threadedly connected to the first bolt. The first bolt is movably connected to the limiting block. The limiting block can penetrate the first slider and abut against the column, thereby locking the position of the first slider.

[0008] Preferably, the fastener is a second bolt, and a set of second bolts is threaded to each end of the first slider. The second bolts can penetrate the first slider and abut against the detection element to lock the detection element.

[0009] Preferably, the detection element includes a second slider, a protractor, and an indicator. The second slider is slidably connected in a cavity on one side of the first slider. The protractor is disposed on the side of the second slider away from the first slider. A set of indicators pointing vertically upwards is rotatably connected at the center of the protractor.

[0010] Preferably, the indicator includes a pointer, a connecting block, and a counterweight, wherein the pointer, the connecting block, and the counterweight are integrally formed along the same axis, and the connecting block is rotatably connected to the center position of the protractor.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By adjusting the height of the detection component, the operator can easily observe the measurement data while standing, avoiding the inconvenience and fatigue caused by squatting or bending over. While standing, the operator's line of sight is more stable, which is conducive to accurately reading the measurement data.

[0013] 2. With the sliding of the first slider, the operator can easily adjust the height of the detection piece to accommodate different heights and operational needs. The design of the locking component ensures the stability of the first slider in the locked state and prevents slippage caused by accidental contact or wind. Locking and unlocking operations are both achieved by rotating the first bolt, which is simple and quick to operate without complicated tools or steps. The support component adopts a welded structure, and the sliding connection design between the first slider and the column is reasonable, ensuring the durability and long-term stability of the device.

[0014] 3. The design of the indicator in this utility model ensures that the pointer can always remain vertically upward, thereby accurately indicating the slope value. The protractor provides a precise scale reading, ensuring the accuracy of the measurement results. The locking mechanism of the second bolt ensures the stability of the detection component during the measurement process and prevents slippage caused by accidental contact or wind.

[0020] 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 protection scope of the present utility model.

[0021] Example 1

[0022] Please refer to Figure 1-4 As shown, this utility model provides an adjustable height highway slope detection device, including a support member, a first slider 1 slidably connected to the support member, a slidable detection element provided on one side of the first slider 1, the detection element can be locked by fasteners, and a locking component is provided on the other side of the first slider 1 to lock the position of the first slider 1.

[0023] The first slider 1 is slidably connected to the support member. It can be slid along the support member by being manually moved. When the first slider 1 is slid, the detection member moves accordingly, thereby changing its height relative to the ground. The first slider 1 is equipped with a locking component to lock its position after the height is adjusted. With the detection member fixed and the first slider 1 locked, the operator can perform slope measurement.

[0024] By adjusting the height of the measuring device, operators can easily observe the measurement data while standing, avoiding the inconvenience and fatigue caused by squatting or bending over. While standing, the operator's line of sight is more stable, which is conducive to accurately reading the measurement data.

[0025] Specifically, the support components include baffles 2 and columns 3. Two sets of baffles 2 are arranged in parallel, and four sets of columns 3 are welded between the two sets of baffles 2. The four sets of columns 3 correspond to the four corners of the baffles 2 respectively. All four sets of columns 3 penetrate the first slider 1 and are slidably connected to it. The locking components include a limiting plate 4, a first bolt 5, and a limiting block 6. The limiting plate 4 is installed in the cavity on one side of the first slider 1. The limiting plate 4 is threadedly connected to the first bolt 5. The first bolt 5 is movably connected to the limiting block 6. The limiting block 6 can penetrate the first slider 1 and abut against the column 3, thereby locking the position of the first slider 1.

[0026] The operator manually moves or pushes the first slider 1, causing it to slide up and down along the column 3, thereby changing the height of the detection piece. When the first slider 1 reaches the desired height, the operator needs to lock its position to prevent further sliding. At this time, the operator rotates the first bolt 5. Since the first bolt 5 is threadedly connected to the limiting plate 4, rotation causes the first bolt 5 to move towards the back of the first slider 1. This movement of the first bolt 5 drives the limiting block 6, which is movably connected to it, to penetrate the first slider 1 and press against the column 3. The contact surface between the limiting block 6 and the column 3 generates friction, thereby preventing further sliding of the first slider 1 and achieving locking. When it is necessary to unlock the first slider 1 for height adjustment, the operator rotates the first bolt 5 in the opposite direction, causing it to move away from the column 3. As the first bolt 5 moves, the limiting block 6 gradually disengages from the column 3, and the first slider 1 returns to its free sliding state.

[0027] By sliding the first slider 1, the operator can easily adjust the height of the detection piece to accommodate different heights and operational needs. The design of the locking component ensures the stability of the first slider 1 in the locked state, preventing slippage caused by accidental contact or wind. Both locking and unlocking operations are achieved by rotating the first bolt 5, which is simple and quick to operate without complicated tools or steps. The support component adopts a welded structure, and the sliding connection design between the first slider 1 and the column 3 is reasonable, ensuring the durability and long-term stability of the device.

[0028] Wherein: the fastener is the second bolt 7, and a set of second bolts 7 are threaded to both ends of the first slider 1. The second bolts 7 can penetrate the first slider 1 to abut against the detection element and lock the detection element. The detection element includes the second slider 8, the protractor 9 and the indicator. The second slider 8 is slidably connected in the cavity on one side of the first slider 1. The protractor 9 is set on the side of the second slider 8 away from the first slider 1. A set of indicators that always point vertically upward is rotatably connected at the center position of the protractor 9. The indicator includes a pointer 10, a connecting block 11 and a counterweight 12. The pointer 10, the connecting block 11 and the counterweight 12 are integrally formed along the same axis, and the connecting block 11 is rotatably connected to the center position of the protractor 9.

[0029] Rotate the second bolt 7 to engage the first slider 1, which will then hold the second slider 8 in place, thus securing the test piece. Place the baffle 2 of the device parallel to the road to be tested. The baffle 2 will form a certain angle with the road surface according to the slope of the road. Under the action of the counterweight 12, the connecting block 11 will rotate along the center position of the protractor 9 to keep the pointer 10 always vertically upward. The scale indicated by the pointer 10 on the protractor 9 is the slope value of the road.

[0030] The design of the indicator allows the pointer 10 to always remain vertically upward, thus accurately indicating the slope value. The protractor 9 provides precise scale readings to ensure the accuracy of the measurement results. The locking mechanism of the second bolt 7 ensures the stability of the detection element during the measurement process and prevents slippage caused by accidental contact or wind.

[0031] Working principle: Rotating the second bolt 7 allows it to enter the first slider 1, which in turn blocks the second slider 8, thus fixing the test piece. The operator manually moves or pushes the first slider 1, causing it to slide up and down along the column 3, thereby changing the height of the test piece. When the first slider 1 reaches the desired height, the operator needs to lock its position to prevent slippage. At this time, rotating the first bolt 5 causes it to move towards the back of the first slider 1 due to its threaded connection with the limiting plate 4. This movement of the first bolt 5 drives the limiting block 6, which is movably connected to it, to penetrate the first slider 1 and block the column 3. The contact surface between the limiting block 6 and the column 3 produces... Friction is generated, thus preventing the first slider 1 from sliding further and achieving locking. When it is necessary to unlock the first slider 1 for height adjustment, the first bolt 5 is rotated in the opposite direction to move it away from the column 3. As the first bolt 5 moves, the limiting block 6 gradually disengages from the column 3, and the first slider 1 returns to a free sliding state. The baffle 2 of the device is placed parallel to the road to be measured. The baffle 2 will form a certain angle with the road according to the slope of the road surface. Under the action of the counterweight 12, the connecting block 11 will rotate along the center position of the protractor 9 to keep the pointer 10 always vertically upward. The scale indicated by the pointer 10 on the protractor 9 is the slope value of the road.
