Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement, in particular to a device for measuring the mileage of a rough mountain road. Background Art

[0002] At a time when forestry resource protection is becoming increasingly important, the construction of new forest fire prevention roads has become a key measure to prevent forest fires and ensure the safety of forest areas. These fire prevention roads are usually located in mountainous areas with complex terrain, rugged mountain roads and large terrain undulations.

[0003] During road construction, the pavement construction phase faces many challenges, among which mileage measurement is a more difficult issue. Due to the rugged nature of mountain roads, mileage measurement during construction is not only difficult to operate, but also prone to large errors. The complex terrain will cause line of sight obstruction, making it difficult for surveyors to perform straight-line measurements. Moreover, on rugged roads, the stability of the measuring equipment is difficult to guarantee, which easily leads to measurement errors. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a device for measuring mileage on a rugged mountain road.

[0005] The utility model adopts the following technical solutions: a device for measuring mileage on a rugged mountain road, comprising a vertical-horizontal conversion suspension device, the outer surface of which is fixedly connected to a square tube frame, the upper surface of which is fixedly connected to a weight placement rack, both sides of the lower surface of which are fixedly connected to spring shock-absorbing auxiliary wheels, the interior of which is rotatably connected to a distance measuring wheel, and a mileage data statistic device being provided on the surface of the square tube frame.

[0006] Through the above technical solution, the circumference of the measuring wheel is 1 meter, and the mileage is calculated by accurately counting the number of rolling circles through the mileage data counter, providing a clear calculation basis for accurate measurement. Measuring twice on both sides of the road and comparing and analyzing the values ​​can effectively avoid measurement deviations caused by special conditions on one side of the road, such as more potholes on one side. Taking the average value can obtain a more accurate mileage.

[0007] As a further improvement of the above solution, the thickness of the square tube skeleton is 40 mm.

[0008] As a further improvement of the above solution, the width of the square tube skeleton is 40 mm.

[0009] As a further improvement of the above solution, the thickness of the heavy object placement rack is 20 mm.

[0010] Through the above technical solution, the unnecessary weight of the device is reduced, the operability and portability of the device are improved, and at the same time, heavy objects can be placed stably. During the measurement process, the gravity of the heavy objects is used to ensure good contact between the device and the ground, which helps to accurately measure.

[0011] As a further improvement of the above solution, the width of the heavy object placement rack is 40 mm.

[0012] Through the above technical solution, the appropriate width ensures the stability of the placement of the weight, preventing the weight from shaking or falling during the measurement process, thereby ensuring the balance and normal operation of the device, which is conducive to improving the accuracy of the measurement.

[0013] As a further improvement of the above solution, the circumference of the distance measuring wheel is 1 meter.

[0014] Through the above technical solution, the clear circumference value provides a direct basis for accurate mileage measurement, making the measurement results more accurate and facilitating the calculation and recording of mileage data.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model places heavy sandbags in a special device for placing heavy objects, and then the car can be started to drive along one side of the road to start measuring the mileage.

[0023] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example:

[0025] Please combine Figure 1-4 The present embodiment provides a device for measuring mileage on a rugged mountain road, comprising a vertical-to-horizontal conversion suspension device 1. A square tube frame 2 is fixedly connected to the outer surface of the vertical-to-horizontal conversion suspension device 1. A weight rack 3 is fixedly connected to the upper surface of the square tube frame 2. Spring shock-absorbing auxiliary wheels 4 are fixedly connected to both sides of the lower surface of the square tube frame 2. A distance measuring wheel 5 is rotatably connected to the interior of the square tube frame 2. A mileage data recorder 6 is provided on the surface of the square tube frame 2. The square tube frame 2 serves to connect the vertical-to-horizontal conversion suspension device 1, the weight rack 3, the spring shock-absorbing auxiliary wheels 4, and to support the distance measuring wheel 5 and the mileage data recorder 6. The appropriate thickness ensures that the device will withstand the forces acting on it from various components during operation, as well as the vibrations and impacts encountered when measuring on a rugged mountain road, without easily deforming. This ensures that the distance measuring wheel 5 can rotate stably and the mileage data recorder 6 can accurately record data.

[0026] The thickness of the square tube skeleton 2 is 40 mm.

[0027] The width of the square tube skeleton 2 is 40 mm.

[0028] The thickness of the weight rack 3 is 20 mm. The thickness of 20 mm can meet the demand of carrying heavy objects such as sandbags without making the weight rack 3 too bulky. It reduces the overall weight while ensuring the structural strength and is reasonably connected with components such as the square tube frame 2.

[0029] The width of the weight rack 3 is 40 mm, which is compatible with the square tube frame 2 and other components, ensuring a stable connection of the weight rack 3 on the square tube frame 2 and being able to stably place weights within a certain width range.

[0030] The circumference of the distance measuring wheel 5 is 1 meter. When the distance measuring wheel 5 rolls, the distance it travels per rotation is 1 meter of the circumference. The mileage data counting instrument 6 calculates the mileage traveled by counting the number of rotations of the distance measuring wheel 5.

[0031] The implementation principle of a device for measuring mileage on a rugged mountain road in the embodiment of the present application is as follows: determine the route to be operated before use, drive the car to one side of the road surface of the route to be measured in advance, install the device on the towing device at the rear of the car through a latch, ensure that the device is installed firmly as a whole without shaking or tilting, carefully adjust the distance measuring wheel 5 to the exact starting point where the mileage measurement will begin, and ensure that the starting position of the distance measuring wheel 5 is accurate by visual observation or with the help of auxiliary tools such as markings, place sandbags in the weight rack 3, generally three to four bags, and ensure that the sandbags are evenly distributed in the weight rack 3 during the placement process to avoid local overweight or too light affecting the balance of the device, and then use ropes or fixing devices to fix it. The sandbags are firmly fixed to prevent them from moving or falling during driving. Find the reset button or operation setting of the mileage data counter 6 and reset its data to zero. At the same time, check whether the display screen of the mileage data counter 6 is normal to ensure that it can accurately record the data. Start the car, slowly accelerate to a constant speed, and drive steadily along the route on one side of the road. During driving, the driver needs to maintain a stable speed and avoid sudden acceleration, sudden braking or frequent lane changes to ensure that the device can smoothly measure the mileage. Continuously observe the readings of the mileage data counter 6 to ensure that it works normally and accurately records the mileage data corresponding to the number of rolling cycles of the distance measuring wheel 5. If the mileage data counter 6 is found to be abnormal such as the reading is If the vehicle jumps or stops counting, the vehicle should be stopped immediately to check the device and restart the measurement after troubleshooting. When the vehicle reaches the predetermined destination or completes the mileage measurement of the road on that side, the vehicle should be stopped slowly and the mileage value displayed on the mileage data counter 6 should be accurately recorded. The value can be recorded in a pre-prepared form or electronic device. At the same time, the value should be checked again to see if it is reasonable to avoid recording errors. The data of the mileage data counter 6 should be reset to zero to prepare for the next measurement. The vehicle should then be driven to the starting position on the inside of the other side of the road. Similarly, the vehicle should be parked stably and safely. The connection of the device should be checked again, especially the connection between the device and the towing device at the rear of the vehicle and the internal structure of the device. The connections between the various components should be ensured to be free of looseness or damage during the previous driving process. Repeat the above operation, that is, slowly start the car to a constant speed state, drive steadily along the inner route of the other side of the road, while maintaining a stable speed and continuously observing the reading of the mileage data statistics instrument 6. When the car completes the mileage measurement of the other side of the road, slowly stop and accurately record the mileage value displayed on the mileage data statistics instrument 6. Compare and analyze the mileage values ​​obtained from the two measurements. If the two values ​​differ greatly, it is necessary to check whether there is a problem with the device or re-measure. If the difference between the two values ​​is within a reasonable range, the average of the two measured values ​​can be calculated as a more accurate mileage for this section of road.

[0032] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
