Description

Technical Field

[0001] This utility model belongs to the field of continuous longitudinal slope section data measurement technology, specifically a data measurement device for continuous longitudinal slope sections of highways. Background Technology

[0002] The continuous longitudinal slope data measurement device for highways is a specialized device for measuring data on continuous longitudinal slope sections of highways. Its main components include a measurement platform, mounting brackets, angle measuring instruments, ultrasonic rangefinders, adjustment mechanisms, and limiting components. With the cooperation of these mechanisms, the device accurately completes the measurement of continuous longitudinal slope sections. The device is mainly installed on roadside supports or fixed objects and uses a laser rangefinder and tilt sensor in conjunction to obtain the required results.

[0003] Existing equipment requires installation on roadside brackets before measurement. Current installation methods involve fixing the equipment directly with screws or using simple assembly / disassembly components. This method is often cumbersome during installation and disassembly, and can delay measurement time in some work. Furthermore, once the measuring equipment is on the roadside bracket, the internal measuring devices cannot be kept level, which increases measurement errors and affects subsequent work. Therefore, we propose a data measurement device for continuous longitudinal slope sections of highways. Utility Model Content

Through the cooperation of the clamping component and the adjustment component, the device can be quickly installed on the roadside bracket and the horizontal angle of the main body of the measuring equipment can be quickly adjusted after installation, which facilitates subsequent measurement, improves measurement efficiency, and is convenient and fast.

[0005] To achieve the above objectives, the specific technical solution is as follows:

[0008] Furthermore, the first limiting component includes a first ratchet fixedly connected to the first rotating shaft on the same axis. A knob is fixed to the front outer wall of the first ratchet. A first stop is fixed to the front outer wall of the first housing near the first ratchet. A first pawl is rotatably connected to the front outer wall of the first housing. A first lever is fixed to the front outer wall of the first pawl. A first spring is fixed to the bottom of the first stop. The end of the first spring away from the first stop is fixedly connected to the first pawl. The first pawl meshes with the first ratchet. A second rectangular cover is fixed near the first ratchet. A second arc-shaped groove is formed on the front outer wall of the second rectangular cover. The second arc-shaped groove is adapted to the first lever.

[0009] Furthermore, the synchronous rotation assembly includes a connecting shaft coaxially fixed to the first rotating shaft, a third synchronous pulley coaxially fixed to the outer wall of the connecting shaft, a second synchronous pulley coaxially fixed to the outer wall of the connecting shaft near the third synchronous pulley, a first synchronous pulley rotatably connected to the front side of the first housing, the first synchronous pulley coaxially fixed to the second lead screw, a fourth synchronous pulley rotatably connected to the outer wall of the front side of the first housing, the fourth synchronous pulley coaxially fixed to the first threaded block, the first synchronous pulley and the second synchronous pulley connected by a first synchronous belt, and the fourth synchronous pulley and the third synchronous pulley connected by a second synchronous belt.

[0010] Furthermore, the adjustment assembly includes a second rotating shaft rotatably connected to the inner wall of the second housing. Two sets of gears are symmetrically fixed to the outer wall of the second rotating shaft. Four sets of sliding grooves are symmetrically opened on the left and right sides of the inner wall of the second housing. Eight sets of sliders are slidably connected to the inner walls of the four sets of sliding grooves. A set of connecting rods is fixedly connected to two sets of sliders on the inner wall of one sliding groove. A rack is fixed to one end of the two sets of connecting rods on the same side near the gear. The rack meshes with the gear. Two sets of third springs are symmetrically fixed to the top of the two sets of racks on the same side. A base plate is fixedly connected to one end of the two sets of third springs away from the rack.

[0013] Compared with the prior art, the beneficial effects of this utility model are at least as follows:

[0014] 1) By setting up a first outer shell, a clamping assembly, and a first limiting assembly, the first outer shell is fixed to the roadside bracket by a set of first clamping blocks and a set of second clamping blocks during use. Then, by rotating the knob, the first rotating shaft drives the second and third synchronous pulleys to rotate. The first and second synchronous belts drive the first and fourth synchronous pulleys to rotate, causing the first and second lead screws to rotate. This, in turn, firmly fixes the first and second clamping blocks to the roadside bracket. When the measuring device is not needed, the first lever is moved to release the first pawl from the first ratchet, allowing the device to be removed from the roadside bracket. Through the above design, quick installation and disassembly can be achieved, which is convenient and fast.

[0015] 2) By setting up a second outer shell, adjustment components, and a second limit component, when the device is fixed in use, if the level on the front side of the measuring device body is not in a horizontal state, the knob is turned so that the second rotating shaft drives the gear to rotate, thereby making fine adjustments to the base plate in the left and right directions, so that the level can be in a horizontal state, which facilitates the accuracy of subsequent measurements. Through the above design, the accuracy of measurement can be improved. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0025] like Figure 1 As shown, this utility model aims to provide a data measurement device for continuous longitudinal slope sections of highways, to solve the problems of inconvenient installation and difficulty in maintaining the level of the measuring equipment after installation in the prior art. Based on the above functions, the entire device includes a first outer shell 1, a second outer shell 2, a support rod 3, a clamping assembly 4, an adjusting assembly 5, a first limiting assembly 6, and a second limiting assembly 7.

[0026] like Figures 2-3As shown, the clamping assembly 4 includes a first rotating shaft 26 rotatably connected to the inner wall of the first housing 1. A first lead screw 24 and a second lead screw 27 are rotatably connected to the inner wall of the first housing 1 on both sides of the first rotating shaft 26. Two sets of first threaded blocks 23 are symmetrically threaded to the outer wall of the left first lead screw 24. A set of first clamping blocks 25 is fixed to the top of each of the two sets of first threaded blocks 23. Two sets of second threaded blocks 29 are symmetrically threaded to the outer wall of the right second lead screw 27. A set of second clamping blocks 28 is fixed to the top of each of the two sets of second threaded blocks 29. A limit stop 30 is fixed at the center of the outer wall of the first threaded block 23. A limit stop 30 is fixed at the center of the outer wall of the second lead screw 27. A first limiting assembly 6 is installed on the rear side of the first rotating shaft 26. A synchronous rotation assembly is installed on the front side of the first rotating shaft 26.

[0027] Specifically, before use, take out the device and check the main body 8 of the measuring device. The main body 8 of the measuring device is the measuring device body. Its main working principle is to fix the main body 8 of the measuring device on the roadside bracket through the device in this embodiment and ensure that the installation is firm. Then, make the main body 8 of the measuring device parallel to the longitudinal slope of the highway to be measured. At this time, the tilt sensor inside the main body 8 of the measuring device is kept horizontal to accurately measure the tilt angle of the device. The microprocessor inside the main body 8 of the measuring device integrates the data and calculates the height difference between the target point and the main body 8 of the measuring device, thereby obtaining the data of the longitudinal slope section of the highway.

[0028] Before installation, adjust the first clamping block 25 and the second clamping block 28 to their maximum width to accommodate the width of the roadside bracket. After engaging the first clamping block 25 and the second clamping block 28 onto the roadside bracket, turn the knob to drive the first rotating shaft 26 to rotate. After the first rotating shaft 26 rotates, the second synchronous wheel 33 and the third synchronous wheel 34 will rotate synchronously. Note that the second synchronous wheel 33 and the third synchronous wheel 34 are coaxially fixed by the same rotating shaft, and there is a rotation space between the second synchronous wheel 33 and the third synchronous wheel 34 so that they do not interfere with each other. Then, the two first lead screws 24 and the second threaded block 29 inside the first housing 1 rotate synchronously. Their power comes from the fourth synchronous wheel 36, the third synchronous wheel 34, the second synchronous wheel 33, and the first synchronous wheel 31. Note that a limit stop 30 is provided in the middle of the outer wall of the first lead screw 24 and the second lead screw 27. This setting is mainly to prevent the first threaded block 23 and the second threaded block 29 from being damaged after excessive rotation.

[0029] It should be mentioned here that after the first outer shell 1 is fixed to the roadside bracket by the clamping assembly 4, if it needs to be disassembled, the first limiting assembly 6 needs to be triggered. The first limiting assembly 6 includes a first ratchet 20 that is coaxially fixedly connected to the first rotating shaft 26. A knob is fixed on the front outer wall of the first ratchet 20. A first stop 16 is fixed on the front outer wall of the first outer shell 1 near the first ratchet 20. A first pawl 21 is rotatably connected to the front outer wall of the first outer shell 1. A first lever 17 is fixed on the front outer wall of the first pawl 21. A first spring 22 is fixed at the bottom of the first stop 16. The end of the first spring 22 away from the first stop 16 is fixedly connected to the first pawl 21. The first pawl 21 meshes with the first ratchet 20. A second rectangular cover 18 is fixed near the first ratchet 20. A second arc-shaped groove 19 is opened on the front outer wall of the second rectangular cover 18. The second arc-shaped groove 19 is adapted to the first lever 17.

[0030] The first limiting component 6 is equipped with a first lever 17 and a first pawl 21. Because of the first pawl 21 and the first lever 17, the first rotating shaft 26 can only rotate in one direction when it is rotating. This setting greatly improves the safety of the equipment after it is fixed. Similarly, if the first outer shell 1 is to be removed, the first lever 17 is to be moved to release the first ratchet 20 from the first ratchet 21. At this time, the knob is turned in the opposite direction, so that the first outer shell 1 is removed from the roadside bracket.

[0031] like Figure 4-6 As shown, the adjustment assembly 5 includes a second rotating shaft 41 rotatably connected to the inner wall of the second housing 2. Two sets of gears 40 are symmetrically fixed to the outer wall of the second rotating shaft 41. Four sets of sliding grooves 15 are symmetrically opened on the left and right sides of the inner wall of the second housing 2. Eight sets of sliders 14 are slidably connected to the inner wall of the four sets of sliding grooves 15. A set of connecting rods 11 is fixedly connected to two sets of sliders 14 on the inner wall of one sliding groove 15. A rack 38 is fixed to one end of the two sets of connecting rods 11 on the same side near the gear 40. The rack 38 meshes with the gear 40. Two sets of third springs 39 are symmetrically fixed to the top of the two sets of racks 38 on the same side. A base plate 10 is fixedly connected to one end of the two sets of third springs 39 away from the rack 38. Two sets of second springs 37 are symmetrically fixed to the bottom of the two sets of racks 38 on the same side. The end of the two sets of second springs 37 away from the rack 38 is fixed to the bottom of the inner wall of the second housing 2. The top of the base plate 10 is fixedly connected to the main body 8 of the measuring device.

[0032] In the above description, once the first outer casing 1 is fixed, if the main body 8 of the measuring device, fixed to the top of the base plate 10, is in a horizontal state, then the adjustment component 5 is not needed. Conversely, if the level 9 inside the main body 8 is not in a horizontal state, then the knob needs to be turned to drive the second rotating shaft 41 to rotate. Two sets of gears 40 are respectively installed on the outer wall of the second rotating shaft 41, with two sets of racks 38 meshing on both sides. Here, when the gears 40 rotate, the racks 38 move up and down simultaneously. At the same time, a third spring 39 and a second spring 37 are respectively installed above and below the racks 38. Their main function is to generate deformation force, making the device more precise during fine adjustments.

[0033] To further explain, after the level 9 is adjusted to be level, if you want to restore it to its original state, simply move the second lever 44 to release the second pawl 43 from restricting the second ratchet 46. When this restriction is released, the level 9 will return to its original state under the restoring force of the third spring 39 and the second spring 37. This design is mainly to accommodate each reassembly and disassembly, because although the installation position is the same each time, the flatness of the road surface is different. Therefore, this design can greatly improve measurement efficiency and reduce measurement errors.

[0034] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0035] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
