Description

Technical Field

[0001] This utility model relates to the technical field of road measurement, and more specifically, to a road slope measuring device. Background Technology

[0002] Slopes are ubiquitous in our geographical environment and are widely used in the construction of roadbeds, river embankments, ditches, stairs, and other structures. The slope must be accurately measured before construction can begin, and it plays a particularly important role in engineering construction.

[0003] Chinese utility model patent with publication number CN211504110U discloses a road slope measuring device, comprising: a measuring device housing; support columns, with two support columns provided on both sides of the front end of the inner cavity of the measuring device housing; wheels, with wheels provided at the four corners of the bottom end of the measuring device housing; a connecting block, with one end of the connecting block provided on the outer wall of the rear end of the measuring device housing, and the bottom end of the connecting block being open; a push rod, with a push rod provided at the other end of the connecting block; and a measuring mechanism, with a measuring mechanism provided at the top of the inner cavity of the measuring device housing.

[0004] The aforementioned road slope measuring device measures road slope by pushing the device to the measurement section, parking the vehicle, and then using a weight inside the measuring rod to allow it to drop freely. The angle indicated by the bidirectional pointer rod is used to read the displayed value. However, since the measurement section has a slope, the wheels need to be braked and positioned before proceeding with the measurement. Existing road slope measuring devices typically use swivel casters with brakes, requiring individual caster locking, which results in poor locking performance, potential vehicle displacement during measurement, and is time-consuming, labor-intensive, and inefficient.

[0043] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0044] like Figure 1 and Figure 2 As shown, a road slope measuring device according to one embodiment of the present invention includes:

[0045] Vehicle body 1;

[0046] The slope measuring component 2 is mounted on the vehicle body 1;

[0047] The moving component 3 includes a moving assembly 4 disposed at the bottom of the vehicle body 1 and a positioning assembly 5. The moving assembly 4 includes a positioning wheel unit 41 disposed at the front end of the vehicle body 1 and a steering wheel unit 42 disposed at the rear end of the vehicle body 1. The positioning wheel unit 41 includes a rotating shaft 411 rotatably connected to the vehicle body 1 and positioning wheel bodies 412 disposed at both ends of the rotating shaft 411. The positioning assembly 5 includes a first positioning unit 51 and a second positioning unit 52. The first positioning unit 51 is used to limit the rotational degree of freedom of the rotating shaft 411. The second positioning unit 52 includes a positioning rod 53 that can move vertically relative to the vehicle body 1 and a positioning drive group 54 that drives the positioning rod 53 to move.

[0048] The aforementioned road slope measuring device limits the rotational freedom of the rotating shaft 411 through the first positioning unit 51 and drives the positioning rod 53 to move in the vertical direction through the positioning drive group 54 of the second positioning unit 52, so that the vehicle body 1 can be parked on the sloped road section. The device is simple to operate, has a stable and reliable parking effect, and facilitates improved measurement efficiency.

[0049] like Figure 2 and Figure 3 As shown, in one embodiment, the first positioning unit 51 includes a first mounting base 511, a first swing rod 512, a clamping block assembly 513, and a connecting rod assembly 514 disposed on the vehicle body 1. The clamping block assembly 513 includes a first clamping block and a second clamping block hinged together, forming a clamping space adapted to the rotating shaft 411 between the first clamping block and the second clamping block. The first swing rod 512 is provided with a hinge portion 5121 hinged to the first mounting base 511, a first drive rod end 5122, a first rod end 5123, and a second rod end 5124. The connecting rod assembly 514 includes a first connecting rod for connecting the first rod end 5123 and the first clamping block, and a second connecting rod for connecting the second rod end 5124 and the second clamping block. Thus, by driving the first drive rod end 5122 to swing relative to the first mounting base 511, the first clamping block and the second clamping block are brought closer to each other, thereby causing the clamping block assembly 513 to come into frictional contact with the rotating shaft 411 in the clamping space.

[0050] In one embodiment, the first positioning unit 51 further includes a spring-loaded assembly 515, which includes a first spring-loaded head hinged to the first clamping block, a second spring-loaded head hinged to the second clamping block, and a first compression spring that presses the first and second clamping blocks away from each other. Thus, by pressing the first and second clamping blocks away from each other using the first compression spring, the clamping space formed between the first and second clamping blocks is initially larger than the diameter of the rotating shaft 411, preventing friction that could affect the normal movement of the vehicle body 1.

[0051] In one embodiment, the first and second clamping blocks are provided with clamping arc plates facing the clamping space. Specifically, the radius of curvature of the clamping arc plates is adapted to the shaft diameter of the rotating shaft 411.

[0052] like Figure 2 and Figure 4 As shown, in one embodiment, the positioning drive assembly 54 includes a second mounting base 541, a second swing rod 542, a second compression spring 543, and a connecting rod 544 disposed on the vehicle body 1; the second mounting base 541 is provided with a guide hole and a blind mounting hole concentrically disposed with the guide hole, the positioning rod 53 is inserted into the guide hole, and the second compression spring 543 is sleeved on the positioning rod 53; the second swing rod 542 is provided with a second drive rod end 5421, a connecting part 5422, and a swing pressing part 5423, the connecting rod 544 connects the second mounting base 541 and the connecting part 5422, and the swing pressing part 5423 is a limiting long groove adapted to the top end of the positioning rod 53; one end of the second compression spring 543 is installed in the blind mounting hole, and the other end presses the second swing rod 542 away from the guide hole. Thus, in the initial state, the second compression spring 543 presses against the swing pressure part 5423 of the second swing rod 542, thereby causing the positioning rod 53 to tend to move upward, avoiding friction between the bottom end of the positioning rod 53 and the ground, which would affect the normal movement of the vehicle body 1; the second drive rod end 5421, which is equivalent to the second mounting seat 541, swings, and the swing pressure part 5423 presses against the second compression spring 543, causing the bottom end of the positioning rod 53 to press against the ground and stop the vehicle body 1.

[0053] In one embodiment, the second positioning unit 52 further includes a positioning bracket disposed on the vehicle body 1, the positioning bracket defining the position of the second drive rod end 5421 by means of a snap-fit ​​groove.

[0054] In one embodiment, the positioning component 5 further includes a linkage rod 55; the linkage rod 55 connects the first drive rod end 5122 and the second drive rod end 5421. Thus, by synchronously driving the first drive rod end 5122 and the second drive rod end 5421 through the linkage rod 55, the front and rear ends of the vehicle body 1 can perform positioning actions simultaneously, making the action simple and quick, and improving measurement efficiency.

[0055] In one embodiment, the positioning rod 53 has a detachably connected rubber block on its end facing the ground. This increases the friction between the rubber block and the ground; simultaneously, the detachable connection allows for the replacement of damaged rubber blocks, thus ensuring effective contact and friction between the positioning rod 53 and the ground.

[0056] like Figure 1 and Figure 5As shown, in one embodiment, the slope measuring component 2 includes a support frame 21 mounted on the vehicle body 1, and a first measuring component 23 detachably connected to the support frame 21 via a connecting structure 22. The first measuring component 23 includes a first measuring disk 231 and a counterweight arrow 232 rotatably connected to the first measuring disk 231. A first measuring mark of the counterweight arrow 232 is provided on the side of the first measuring disk 231. Thus, utilizing the characteristic that gravity is vertically downward, the first measuring disk 231 tilts with the slope of the measured road section, and the position of the first measuring mark pointed to by the counterweight arrow 232 changes, thereby displaying the slope value.

[0057] In one embodiment, the slope measuring component 2 further includes a second measuring assembly 24 disposed on the top of the support frame 21. The second measuring assembly 24 includes a second measuring disk 241 fixedly connected to the top of the support frame 21 and a collar unit 242 rotatably connected to the top of the support frame 21. The collar unit 242 includes a collar member 243, a second pointer 244 fixedly connected to the collar member 243, and a counterweight disposed within the collar member 243. The second pointer 244 and the counterweight are respectively disposed on the two end faces of the same diameter of the collar member. Thus, utilizing the characteristic that the direction of gravity is vertically downward, the counterweight makes the second pointer 244 on the collar member 243 always vertically upward. The second measuring disk 241 tilts with the slope of the measured road section, and the position of the second measuring mark on the second measuring disk 241 pointed to by the second pointer 244 changes, thus displaying the slope value.

[0058] In one embodiment, the support frame 21 has an inverted U-shaped structure, including a horizontal round rod 211 and supporting round rods 212 disposed at both ends of the horizontal round rod 211; the collar 243 is rotatably connected to the horizontal round rod 211; the connecting structure 22 includes a hinge assembly 221 connecting the horizontal round rod 211 and the first measuring disk 231, and pin positioning units 222 disposed on both sides of the first measuring disk 231. Thus, the hinge assembly 221 ensures that the plane of the first measuring disk 231 is vertically positioned when measuring the road section, preventing friction when the counterweight arrow 232 points to the second measuring mark, which would affect the measurement effect; simultaneously, the pin positioning units 222 prevent the first measuring disk 231 from swinging with the movement of the vehicle body 1, avoiding collisions and damage during daily movement.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
