Description

Technical Field

[0001] This invention relates to the field of road inspection technology, and in particular to a road crack detection device. Background Technology

[0002] Roads, as vital channels for people's travel and the flow of goods, are inseparable from our lives. Different roads have different construction standards, maintenance cycles, and service life from the initial design and construction stage. However, harsh usage environments such as extreme weather, rain and snow, increased heavy vehicles, and construction of surrounding areas and roadbeds can cause the "health" of roads to deteriorate rapidly in a short period of time. By inspecting roads, it is easier to repair problems in a timely manner.

[0003] Existing road crack detection devices can move with vehicles and are essentially a single, integrated frame. This makes them unsuitable for roads of varying widths, hindering flexible application and detection, and negatively impacting overall work efficiency.

[0004] Therefore, in order to solve this problem, we propose a road crack detection device. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a road crack detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A road crack detection device includes two connecting rods, which are arranged in parallel and slidably connected. Each of the two connecting rods has an L-shaped rod fixed at one of its opposite ends. The two L-shaped rods are symmetrically arranged, and several mounting frames are provided between the two L-shaped rods. The detection device body is fixedly installed inside the mounting frame. Four support blocks are symmetrically fixed at the bottom of the mounting frame. A fixing mechanism is provided between two support blocks aligned with the two mounting frames. The support blocks are matched with a support wheel mechanism. A tie rod mechanism is matched in the middle of the mounting frame.

[0008] Both connecting rods are rotatably provided on their upper sides. The ends of the two connecting rods opposite to the connecting rods are aligned and rotatably connected. One connecting rod has an upper mounting rod that rotates vertically on its upper side opposite to the connecting rod, and the other connecting rod has a lower mounting rod that rotates vertically on its lower side opposite to the connecting rod.

[0009] Preferably, the two connecting rods are provided with a plurality of through holes evenly distributed on their sides, the plurality of through holes of the two connecting rods are matched and aligned, and the two connecting rods are fixed by bolts passing through the aligned through holes.

[0010] Preferably, the fixing mechanism includes a rectangular insert and two fixing pins. The two aligned support blocks are each provided with a rectangular hole that matches the rectangular insert. One end of the fixing pin is coaxially fixed with a fixing threaded rod. The sides of the two aligned support blocks are each provided with a threaded hole that matches the fixing threaded rod. The rectangular insert is provided with a first insertion hole that matches the two fixing pins. The two rectangular holes are each provided with a slot that matches the fixing pin. The orientation of the first insertion hole and the slot are perpendicular to the orientation of the rectangular hole.

[0011] Preferably, the support wheel mechanism includes a roller and a connecting block. One end of the connecting block is rotatably connected to the roller on the same axis. The connecting block is inserted into and matched with the rectangular hole of the support block. The connecting block is provided with a second insertion hole that matches the fixing pin.

[0012] Preferably, the tie rod mechanism includes two bent rods symmetrically arranged inside the mounting frame. The shape of the bent rods is the same as the edge shape of the mounting frame. The same end of both bent rods is rotatably connected to the mounting frame. A handle is fixed between the other ends of the two bent rods. One end of one bent rod is fixedly connected to the mounting frame by a fixing knob.

[0013] Preferably, the bending rod is telescopic in the middle and is equipped with a fastening knob, and a protective shell is fixed between the two bending rods.

[0014] Preferably, the mounting frame and the rotating end of the bending rod are fixed with two positioning blocks. The two positioning blocks are respectively aligned and matched with the two bending rods on the mounting frame. The positioning block is provided with an inclined surface, and a retaining spring block is fixed on the inclined surface. The corresponding bending rod is provided with a retaining groove that matches the retaining spring block.

[0015] Preferably, cylindrical rods are fixed at both ends of the two L-shaped rods on opposite sides, and the top of the mounting frame and the positioning block on the same side are respectively provided with round holes that match the two cylindrical rods.

[0016] Preferably, a support rod is horizontally fixed to the top of the upper mounting rod, and a screw rod is vertically threaded through one end of the support rod, with a rubber abutment fixed to the bottom of the screw rod.

[0017] Preferably, a docking ring is fixed to the bottom side of the lower mounting rod, and the ring hole of the docking ring faces the two L-shaped rods.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, two telescopically adjustable connecting rods and L-shaped rods at both ends are provided. Several assemblies of mounting frames and detection device bodies can be set between the two L-shaped rods. By connecting the connecting rods to external vehicles, the assemblies of mounting frames and detection device bodies can be pulled and moved. At the same time, the telescopic adjustment of the two connecting rods can flexibly adjust the number of mounting frames, thereby setting the number of mounting frames and corresponding detection device bodies according to the road width, effectively improving the detection efficiency and achieving flexible application and detection effects.

[0020] 2: This invention, by setting two bending rods that match the mounting frame, enables the mounting frame to be removed and moved independently, facilitating careful inspection of the road by staff. Furthermore, by setting a protective shell that is fixed to the bending rods, an effective protective effect is achieved when the bending rods are retracted. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figure 1-7 A road crack detection device includes two connecting rods 1, which are parallel and slidably connected, and the two connecting rods 1 can be adjusted by sliding. An L-shaped rod 2 is fixed to one of the opposite ends of each connecting rod 1. The two L-shaped rods 2 are symmetrically arranged, and several mounting frames 3 are provided between the two L-shaped rods 2. A detection device body 4 is fixedly installed inside the mounting frame 3. The detection device body 4 is an existing ground-penetrating radar device, capable of detecting cracks and potential underground cavities, and can meet the requirements for high-speed mobile detection. The distance between the two L-shaped rods 2 can be adjusted to flexibly set the number of mounting frames 3 and corresponding detection device bodies 4. Four support blocks 5 are symmetrically fixed to the bottom of the mounting frame 3. A fixing mechanism is provided between the two aligned support blocks 5 of the two mounting frames 3, and the mounting frames 3 can be fixedly connected to each other. The support blocks 5 are matched with support wheel mechanisms, and a tie rod mechanism is matched in the middle of the mounting frame 3, allowing individual mounting frames 3 to be moved and used independently.

[0031] Both connecting rods 1 are rotatably equipped with docking rods 6 on their upper sides. The ends of the two docking rods 6 facing away from the connecting rods 1 are aligned and rotatably connected. When the two connecting rods 1 are slidably adjusted, the two docking rods 6 serve to restrict and connect the two connecting rods 1 without hindering their sliding. Furthermore, one docking rod 6 has an upper mounting rod 7 vertically rotatably mounted on its upper side facing away from the connecting rod 1, and the other docking rod 6 has a lower mounting rod 8 vertically rotatably mounted on its lower side facing away from the connecting rod 1. Both the upper mounting rod 7 and the lower mounting rod 8 are used for installation and docking with existing vehicles.

[0032] As a technical optimization of the present invention, a plurality of through holes 9 are evenly provided on the sides of the two connecting rods 1. The plurality of through holes 9 of the two connecting rods 1 are matched and aligned. The two connecting rods 1 are fixed by bolts passing through the aligned through holes 9. After the two connecting rods 1 are slidably adjusted, the position of the bolts can be adjusted and fixed by bolts passing through the aligned through holes 9.

[0033] As an optimized technical solution of the present invention, the fixing mechanism includes a rectangular insert 10 and two fixing pins 11. Each of the two aligned support blocks 5 has a rectangular hole 12 that matches the rectangular insert 10, allowing the rectangular insert 10 to be inserted into the rectangular holes 12 of the two aligned support blocks 5. One end of each fixing pin 11 is coaxially fixed with a fixing threaded rod 13. Each of the two aligned support blocks 5 has a threaded hole on its side that matches the fixing threaded rod 13. The rectangular insert 10 has a first insertion hole 14 that matches the two fixing pins 11. Each of the two rectangular holes 12 has a slot 15 that matches the fixing pin 11. The orientation of the first insertion hole 14 and the slot 15 is perpendicular to the orientation of the rectangular hole 12. The fixing pin 11 is inserted into the first insertion hole 14 of the rectangular insert 10 and abuts against the bottom of the slot 15 within the rectangular hole 12, achieving a locking effect on the rectangular insert 10. The two fixing pins 11 effectively fix the rectangular insert 10, thereby fixing the two support blocks 5 through the rectangular insert 10.

[0034] As a technical optimization of the present invention, the support wheel mechanism includes a roller 16 and a connecting block 17. One end of the connecting block 17 is rotatably connected to the roller 16 on the same axis. The connecting block 17 is inserted into and matched with the rectangular hole 12 of the support block 5. The connecting block 17 is provided with a second insertion hole 18 that matches the fixing pin 11. The installation roller 16 facilitates the movement of the mounting frame 3.

[0035] As a technical optimization of the present invention, the lever mechanism includes two bent rods 19 symmetrically arranged inside the mounting frame 3. The shape of the bent rods 19 is the same as the edge shape of the mounting frame 3. The same end of the two bent rods 19 is rotatably connected to the mounting frame 3. A handle 20 is fixed between the other ends of the two bent rods 19. One end of one bent rod 19 is fixedly connected to the mounting frame 3 by a fixing knob.

[0036] As a technical optimization of the present invention, the bending rod 19 is telescopically arranged in the middle and is matched with a fastening knob. A protective shell 21 is fixed between the two bending rods 19. The protective shell 21 is detachable and serves as a protective function.

[0037] As a technical optimization of the present invention, two positioning blocks 22 are fixed at one end of the mounting frame 3 and the bending rod 19. The two positioning blocks 22 are respectively aligned and matched with the two bending rods 19 on the mounting frame 3. The positioning block 22 is provided with an inclined surface, and a retaining spring block 23 is fixed on the inclined surface. The corresponding bending rod 19 is provided with a retaining groove that matches the retaining spring block 23.

[0038] As a technical optimization of the present invention, cylindrical rods 24 are fixed at both ends of the opposite side of the two L-shaped rods 2. The top of the mounting frame 3 and the positioning block 22 on the same side are respectively provided with round holes that match the two cylindrical rods 24. The two cylindrical rods 24 on the two L-shaped rods 2 are respectively inserted into the round holes of the top of the mounting frame 3 and the positioning block 22 on the same side. Then, two connecting rods 1 are fixed, thereby effectively restricting the several mounting frames 3 and the corresponding detection device body 4.

[0039] As a technical optimization of the present invention, a support rod 25 is horizontally fixed at the top of the upper mounting rod 7, and a screw 26 is vertically threaded through one end of the support rod 25. A rubber abutment 27 is fixed at the bottom of the screw 26.

[0040] As a technical optimization of the present invention, a docking ring 28 is fixed on the bottom side of the lower mounting rod 8, and the ring hole of the docking ring 28 faces the two L-shaped rods 2.

[0041] In use, the several mounting frames 3 and corresponding detection device bodies 4 below the two connecting rods 1 can be set up as needed. The two connecting rods 1 can be slidably adjusted to change the distance between the two L-shaped rods 2, and then fixed by bolts passing through aligned through holes 9. Increasing the distance between the two L-shaped rods 2 facilitates the setting of more mounting frames 3 and corresponding detection device bodies 4, and similarly, decreasing the distance between the two L-shaped rods 2 reduces the number of mounting frames 3 and corresponding detection device bodies 4 required. Therefore, the number of mounting frames 3 and corresponding detection device bodies 4 can be set according to the width of the road. For example, more mounting frames 3 and corresponding detection device bodies 4 can be set up on wider roads to improve detection efficiency, while fewer mounting frames 3 and corresponding detection device bodies 4 can be set up on narrower roads to facilitate detection, ultimately achieving flexible application and detection results.

[0042] When increasing the number of mounting frames 3 and corresponding detection device bodies 4, align the sides of the two mounting frames 3 so that the corresponding support blocks 5 are aligned in pairs. Then, insert the corresponding rectangular inserts 10 into the rectangular holes 12 of the two aligned support blocks 5. Next, insert two fixing pins 11 from the sides of the two support blocks 5 respectively, and screw the fixing threaded rods 13 into the threaded holes of the support blocks 5. Finally, the fixing pins 11 are inserted into the first insertion hole 14 of the rectangular insert 10 and abut against the bottom of the slot 15 in the rectangular hole 12, achieving a locking effect on the rectangular insert 10. The two fixing pins 11 effectively fix the rectangular insert 10, thereby fixing the two support blocks 5 through the rectangular insert 10. Through the above operations, the aligned support blocks 5 can be fixed to each other, thereby fixing the two mounting frames 3. The operation is convenient, and similarly, convenient disassembly operations can also be performed.

[0043] After several mounting frames 3 and corresponding detection device bodies 4 are connected, the two connecting rods 1 are slidably adjusted so that the two L-shaped rods 2 are positioned at both ends of the mounting frames 3. The two cylindrical rods 24 on the two L-shaped rods 2 are inserted into the round holes of the top of the mounting frame 3 and the positioning block 22 on the same side, respectively. Then the two connecting rods 1 are fixed to effectively restrict the several mounting frames 3 and corresponding detection device bodies 4, so that the two connecting rods 1 can pull the combination of several mounting frames 3 and corresponding detection device bodies 4.

[0044] After several mounting frames 3 and corresponding detection device bodies 4 are connected, rollers 16 are installed on the support blocks 5 on the outer sides of the mounting frames 3 at both ends. The connecting blocks 17 of the rollers 16 are inserted into the rectangular holes 12 of the support blocks 5, and then the fixed threaded rods 13 are rotated and screwed into the threaded holes of the support blocks 5, so that the fixed pins 11 are inserted into the second insertion holes 18 and abut against the slots 15, thus achieving the effect of convenient installation.

[0045] Then, the docking ring 28 is fixed to the existing vehicle's towing hook, and the screw 26 is rotated so that the screw 26 moves downward, causing the rubber block 27 to abut against the roof of the vehicle, thereby effectively positioning the two docking rods 6 and the connecting rod 1, effectively ensuring the stable traction of the assembly of several mounting frames 3 when the vehicle is moving.

[0046] Meanwhile, the individual mounting frame 3 can also be removed and moved independently for easy inspection of the road by staff. The individual mounting frame 3 is equipped with casters 16 on all four sides. After removing the protective outer shell 21 and taking out the corresponding fixing knob, the two bending rods 19 are rotated out using the handle 20, causing them to engage with the spring clips 23 on the corresponding positioning blocks 22. The entire mounting frame 3 can then be moved by pushing the handle 20, allowing for inspection operations in conjunction with the inspection device body 4. When the two bending rods 19 are retracted, the protective outer shell 21 is installed, providing effective protection and dust protection.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
