Description

Technical Field

[0001] This utility model relates to the field of road slope detection technology, specifically to a road slope detection device. Background Technology

[0002] In road engineering construction, maintenance, and traffic planning, road slope detection is a crucial foundational task. Accurate slope data is key to assessing the rationality of road design, ensuring traffic safety, and optimizing drainage systems. Currently, the most common road slope detection technology uses electronic detection equipment. This equipment typically incorporates tilt sensors, data processors, and display modules. During use, the equipment is placed in the area to be tested. The tilt sensor detects the road surface's inclination angle, the data processor converts and processes the signal, and the final result is displayed on the display module. Workers obtain road slope information by reading the displayed data. Another method relies on manual measurement using a level and measuring tape. First, a level is used to establish a horizontal reference. Then, the height difference and horizontal distance between two specific points on the road surface are measured using a measuring tape, and the road slope is calculated using trigonometric functions.

[0003] However, existing detection technologies have significant shortcomings. Electronic detection equipment, with its numerous internal electronic components, not only increases overall equipment cost and investment but also places high demands on the operating environment. These components are prone to malfunction in harsh conditions such as humidity, high temperatures, and severe vibration. Once a component fails, the entire equipment ceases to function properly, severely limiting its applicability in various environments. Furthermore, electronic equipment requires regular charging or battery replacement, and its data processing is complex and susceptible to interference, impacting detection efficiency and data stability. Manual detection using a level and measuring tape is cumbersome, requiring repeated adjustments to the level and precise measurements of height differences and horizontal distances. This is not only labor-intensive and time-consuming, resulting in low efficiency, but also prone to inaccurate data due to operational errors, failing to meet the demands for rapid and accurate slope detection. In addition, some existing testing devices lack effective component fixing structures, making the internal testing components prone to shaking and collisions during movement, leading to component damage and shortening the device's service life. Furthermore, the lack of stable limiting mechanisms for the testing components during the testing process makes them susceptible to external interference, affecting the stability of the testing data. During reset, rapid collisions of components can also damage the device, further reducing the practicality and reliability of existing testing devices. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a road slope detection device. This utility model can detect the slope inclination angle of a road through the cooperation of a counterweight ball, a connector, a ratchet, a pointer and a scale. The detection principle is simple and intuitive, the operation is convenient, and there is no need for complicated electronic equipment assistance, which reduces the detection cost. At the same time, it also reduces the situation where the detection cannot be carried out due to the failure of electronic components, and improves the applicability of the device in different environments.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: a road slope detection device, including a trolley, a top cover, a ratchet, a connector, a counterweight ball, a pointer, a scale, a mounting base, a ratchet tooth, a tension spring, and an unlocking component. The top cover is installed on the top of the trolley, the ratchet is rotatably connected to the inside of the trolley, the connector is fixed to the drive shaft of the ratchet, the counterweight ball is fixed to the end of the connector, the pointer is fixed to the drive shaft of the ratchet, the scale is embedded in the side wall of the trolley, the mounting base is fixed to the inner wall of the trolley by bolts, the ratchet tooth is rotatably connected to the mounting base, the tension spring is connected between the mounting base and the ratchet tooth, the unlocking component is rotatably connected to the ratchet tooth, and the unlocking component passes through the upper part of the trolley. It also includes a locking mechanism and a buffer mechanism. The locking mechanism is used to lock and limit the connector, and the buffer mechanism is used to limit the connector when it is reset.

[0006] More preferably, as the counterweight ball rotates, it drives the connector, ratchet, and pointer to rotate, which allows the inclination angle of the road slope to be measured.

[0007] More preferably, the locking mechanism includes a mounting frame, a locking element, and a limiting block. The mounting frame is fixed to the side of the trolley, the locking element is threadedly installed in the mounting frame, the limiting block is fixed to the end of the locking element, the limiting block slides on the trolley, and the connecting element has a groove that mates with the limiting block.

[0008] More preferably, the limiting block can be locked and limited by moving into the slot on the connector.

[0009] More preferably, the buffer mechanism includes a contact block, a damper, and a spring. The contact block is slidably connected to the side of the trolley via symmetrically arranged dampers, and the spring is connected between the contact block and the inner wall of the trolley.

[0010] More preferably, the contact block can buffer the connector when the connector is reset, preventing the counterweight ball from causing the connector to rotate and reset, which would damage the trolley.

[0011] Compared with the prior art, the advantages of this utility model are: this utility model can detect the slope and inclination angle of a road by using a counterweight ball, a connector, a ratchet, a pointer and a scale. The detection principle is simple and intuitive, and the operation is convenient. It does not require the assistance of complex electronic equipment, which reduces the detection cost. At the same time, it also reduces the situation where the detection cannot be carried out due to the failure of electronic components, and improves the applicability of the device in different environments.

[0012] Equipped with a locking mechanism, the connectors and counterweight balls can be locked and limited during normal movement of the trolley, preventing them from swinging freely during movement and avoiding collisions with other internal components of the trolley that could cause damage. It also reduces noise during movement, ensures the overall structural stability of the device during trolley movement, and extends the service life of the components.

[0013] During the testing process, the ratchet and ratchet engage and, under the action of the tension spring, lock and limit the connection, effectively preventing slight external vibrations or interference from causing the connection, ratchet, and pointer to shift. This ensures the pointer position remains stable during the testing process, thereby guaranteeing the accuracy of the test data and reducing testing errors.

[0014] A buffer mechanism is provided. When the connector is reset, the contact block, in conjunction with the damper and spring, can buffer the reset rotation of the connector, slow down the reset speed of the connector, and prevent the counterweight ball from driving the connector to rotate rapidly during reset and causing a violent collision with the inner wall of the trolley. This prevents the trolley and related components from being damaged by impact, further extends the overall service life of the device, and improves the safety and stability of the reset process.

[0026] Example: As shown in the attached figures, a road slope detection device includes a trolley 1, a top cover 2, a ratchet 3, a connector 4, a counterweight ball 5, a pointer 6, a scale 7, a mounting base 8, a ratchet tooth 9, a tension spring 10, and an unlocking component 11. The top cover 2 is mounted on the top of the trolley 1. The ratchet 3 is rotatably connected to the inside of the trolley 1. The connector 4 is fixed to the drive shaft of the ratchet 3. The counterweight ball 5 is fixed to the end of the connector 4. The pointer 6 is fixed to the drive shaft of the ratchet 3. The scale 7 is embedded in the side wall of the trolley 1. As the counterweight ball 5 rotates, it drives the connector 4, the ratchet 3, and the pointer 6 to rotate. With the help of the scale 7, the inclination angle of the road slope can be measured. The mounting base 8 is fixed to the inner wall of the trolley 1 by bolts. The ratchet 9 is rotatably connected to the mounting base 8. The ratchet 9 cooperates with the ratchet 3 to lock and limit the connecting part 4. The tension spring 10 is connected between the mounting base 8 and the ratchet 9. The unlocking part 11 is rotatably connected to the ratchet 9. The unlocking part 11 passes through the upper part of the trolley 1. It also includes a locking mechanism 12 and a buffer mechanism 13. The locking mechanism 12 is used to lock and limit the connecting part 4. The buffer mechanism 13 is used to limit the connecting part 4 when it is reset.

[0027] In this embodiment, the locking mechanism 12 specifically includes a mounting frame 121, a locking member 122, and a limiting block 123. The mounting frame 121 is fixed to the side of the trolley 1. The locking member 122 is threadedly installed in the mounting frame 121. The limiting block 123 is fixed to the end of the locking member 122 and slides on the trolley 1. The connecting member 4 has a slot that cooperates with the limiting block 123. The limiting block 123 can lock and limit the connecting member 4 and the counterweight ball 5 by moving and engaging the slot on the connecting member 4. Furthermore, the buffer mechanism 13 includes a contact block 131, a damper 132, and a spring 133. The contact block 131 is slidably connected to the side of the trolley 1 through the symmetrically arranged dampers 132. When the connector 4 is reset, the contact block 131 can buffer the connector 4 to prevent the counterweight ball 5 from driving the connector 4 to rotate and reset, which would damage the trolley 1. The spring 133 is connected between the contact block 131 and the inner wall of the trolley 1.

[0028] When using the road slope detection device, if the trolley 1 is in its normal moving state, the connecting part 4 and the counterweight ball 5 can be locked by the locking mechanism 12 to prevent them from shaking randomly during movement. Since the mounting frame 121 of the locking mechanism 12 is fixed to the side of the trolley 1, and the locking part 122 is threadedly installed in the mounting frame 121, rotating the locking part 122 will push the limiting block 123 to slide on the trolley 1, so that the limiting block 123 moves and gets into the slot opened on the connecting part 4, thereby stably locking the connecting part 4. This prevents the connecting part 4 from causing the counterweight ball 5 to shake due to bumps and vibrations when the trolley 1 moves, and avoids collisions between the connecting part 4, the counterweight ball 5 and other internal parts of the trolley 1 during shaking, which would cause damage. At the same time, it can also reduce the noise generated during movement and ensure the overall structural stability of the device during the movement of the trolley 1.

[0029] When road slope detection is required, the locking mechanism 12 must first be released from locking the connector 4. The locking member 122 is then rotated in the opposite direction, causing the limiting block 123 to disengage from the slot of the connector 4, allowing the connector 4 to return to a rotatable state. The trolley 1 is then moved to the area of ​​the road to be tested and placed stably. Due to the slope of the road, the trolley 1 tilts with the road surface. The counterweight ball 5, fixed to the end of the connector 4, maintains a vertical downward trend under gravity, thus causing the connector 4 to rotate. Since the connector 4 is fixed to the drive shaft of the ratchet 3, the rotation of the connector 4 synchronously drives the drive shaft of the ratchet 3 and the pointer 6 fixed to that drive shaft to rotate. After the counterweight ball 5 comes to rest and the pointer 6 stabilizes, the tilt angle of the road slope can be read by observing the pointer 6's orientation on the scale 7 embedded in the side wall of the trolley 1, thus completing the slope detection.

[0030] During testing, the mounting base 8 is bolted to the inner wall of the trolley 1. The ratchet 9, rotatably connected to the mounting base 8, engages with the ratchet 3. Under the tension of the tension spring 10, the ratchet 9 locks the ratchet 3, thus locking and limiting the connection 4. This prevents slight external interference from causing the connection 4, ratchet 3, and pointer 6 to deviate, ensuring stable test data. When resetting is required after testing, the unlocking piece 11, which passes through the upper part of the trolley 1 and is rotatably connected to the ratchet 9, is pulled upwards. The unlocking piece 11 drives the ratchet 9 to rotate upwards against the tension of the tension spring 10, releasing the lock on the ratchet 3. The connection 4 and the counterweight ball 5 then reset and rotate under gravity. At this time, the contact block 131 of the buffer mechanism 13 will contact the connector 4. The contact block 131 is slidably connected to the side of the cart 1 through the symmetrically arranged dampers 132. The dampers 132 generate damping force to slow down the sliding of the contact block 131. At the same time, the spring 133 connected to the contact block 131 and the inner wall of the cart 1 undergoes elastic deformation to absorb the impact energy. Together, they play a buffering role in resetting the connector 4, preventing the counterweight ball 5 from driving the connector 4 to quickly reset and impact the cart 1, causing damage, extending the service life of the device, and improving the safety of use.

[0031] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
