Description

Technical Field

[0001] This invention relates to the field of dump truck technology, and in particular to a loading alignment and anti-overshooting device for heavy-duty mining dump trucks. Background Technology

[0002] Mining dump trucks are heavy-duty trucks used in mining areas and construction sites to transport bulk materials such as ore and sand, and are capable of automatic unloading. Their maximum gross vehicle weight and maximum axle load exceed highway regulations, and they can only operate on designated road sections.

[0003] Safety issues frequently arise with open-pit coal mine dump trucks during operation, making driving safety paramount. Due to their large size, mining dump trucks create significant blind spots for drivers, posing safety hazards. A common method to address blind spots is using onboard 360-degree panoramic cameras, which reduce blind spots and assist drivers, proving effective in smaller vehicles. However, when applied to mining dump trucks, the dusty and gravelly environment, coupled with the fact that 360-degree assisted driving is not needed during normal driving (only for reversing and passing), easily leads to camera accumulating dust and requiring frequent cleaning. Therefore, a positioning and anti-overshooting device for heavy-duty mining dump trucks is needed to address this issue. Summary of the Invention

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figures 1-3 and Figures 6-9 This is the first embodiment of the present invention. This embodiment provides a loading alignment and anti-overshooting device for a heavy-duty dump truck used in mining. Through the designed protective mechanism 200 and wiping mechanism 300, it can protect the camera on the outside of the vehicle separately, preventing external dust from adhering to its outside and making its shooting effect better.

[0036] Specifically, it includes front and rear cameras 100 installed at the front and rear of a heavy-duty mining dump truck, and side cameras 101 on both sides of the truck. It also includes a mounting frame 102 for installing the front and rear cameras 100. The mounting frame 102 is installed at the front or rear of the heavy-duty mining dump truck, and a protective mechanism 200 for camera protection is installed inside the mounting frame 102. It also includes a mounting bracket 103 for installing the side cameras 101. The mounting bracket 103 is fixed to the side of the heavy-duty mining dump truck, and a wiping mechanism 300 for cleaning the side cameras 101 is installed on the mounting bracket 103. The wiping mechanism 300 includes a rotating component 301 and a connecting rod 302 that slides through the mounting bracket 103. One end of the connecting rod 302 is inserted into the rotating component 301, and the other end is fixed with a wiping component 303 for wiping the outside of the side cameras 101.

[0037] It should be noted that in this solution, the protective mechanism 200 can protect the head and tail cameras 100 and prevent dust from adhering. At the same time, the rotating component 301 and the wiping component 303 in the wiping mechanism 300 work together to block and clean the side camera 101.

[0038] It should also be noted that the 360-degree panoramic camera mentioned in this solution is the existing 360-degree surround view security monitoring system. It mainly consists of two head and tail cameras 100 and two side cameras 101 on both sides to capture images of the outside of the vehicle and stitch the images into a 360-degree video without blind spots, thereby facilitating the passing of oncoming vehicles and reversing.

[0039] It should be noted that: (referring to...) Figures 3-5 The wiping assembly 303 includes a connecting plate 303a fixed to the docking rod 302. The outer end of the connecting plate 303a is fixed with a docking seat 303b, and a cleaning cap 303c is docked through the docking seat 303b. The cleaning cap 303c is provided with lint for wiping the side camera 101. A rotating component 303d for rotating the cleaning cap 303c is installed on the docking seat 303b. Two end rods 303e and a limiting rod 303f are fixed to the outer side of the mounting bracket 103. The outer side of the connecting plate 303a has a notch 303g that is adapted to the end rods 303e and the limiting rod 303f.

[0040] Among them, the outer edge of the cleaning cap 303c is fixed with a docking ring 303c-1 that is slidably connected to the docking seat 303b. The cross-sectional shape of the connection between the docking seat 303b and the docking ring 303c-1 is L-shaped, and the cross-sectional shape of the docking ring 303c-1 is an inverted L-shaped that matches it. The rotating component 303d includes a rotating motor 303d-1 that is fixedly mounted on the docking seat 303b via a motor frame. The output end of the rotating motor 303d-1 is fixed with a rotating gear 303d-2 via a coupling. The outer side of the docking ring 303c-1 is fixed with a rotating gear ring 303d-3 that meshes with the rotating gear 303d-2.

[0041] The principle behind wiping and dust removal from the side camera 101: Refer to... Figure 3 First, the rotating assembly 301 drives the docking rod 302 to rotate until it abuts against the end rod 303e near the camera. Then, the docking rod 302 is moved down until the cleaning cap 303c is fastened to the outside of the side camera 101. Then, the rotating motor 303d-1 rotates, driving the rotating gear 303d-2 to rotate, causing the rotating gear ring 303d-3 to rotate as well. This allows the cleaning cap 303c to be fastened to the outside of the camera and rotate simultaneously, using the lint inside the cleaning cap 303c to remove dust adhering to the outside of the camera.

[0042] It is worth noting that when the vehicle is passing or reversing, the rotating component 301 will first drive the connecting plate 303a to rise, so that the cleaning cap 303c is detached from the camera, and then rotate in the opposite direction, so that the connecting plate 303a abuts against the end rod 303e at the other end. At the same time, this solution has a baffle plate 303c-2 installed on the mounting bracket 103 for the cleaning cap 303c to abut against. The baffle plate 303c-2 can effectively prevent dust from entering the cleaning cap 303c.

[0043] It should also be noted that the lengths of the two end rods 303e in this design are longer than those of the limiting rod 303f. When the notch 303g on the outer side of the connecting plate 303a abuts against the limiting rod 303f and the end rod 303e, the connecting plate 303a can be stably moved up and down, making its engagement with the camera more precise.

[0044] Meanwhile, in this plan, refer to Figure 4 and Figure 5 The rotating assembly 301 includes a drive member 301a and a rotating tube 301b fixed in the mounting bracket 103. The outer side of the rotating tube 301b is fixed to the inner side of the mounting bracket 103 by a bearing bracket, and the rotating tube 301b is sleeved on the outer side of the docking rod 302. The outer side of the rotating tube 301b is engraved with a threaded groove, and the bottom of the docking rod 302 is fixed with a threaded block 301c that is opposite to the threaded groove. The inner side of the rotating tube 301b is provided with an annular groove 301d near the end of the drive member 301a, and a compression spring 301e for pushing the threaded block 301c outward is fixed in the annular groove 301d. The outer side of the mounting bracket 103 is fixed with a stop plate 301f that abuts against the docking rod 302.

[0045] It should be noted that when the threaded block 301c moves into the annular groove 301d, the connecting plate 303a is in contact with the outer wall of the mounting bracket 103. At the same time, when the rotating tube 301b reverses, the compression spring 301e makes it easy for the threaded block 301c to reconnect with the threaded groove, thereby allowing it to move upward along the threaded groove.

[0046] The driving component 301a includes a driving motor 301a-1 fixed in the mounting bracket 103, a driving gear 301a-2 fixed at the output end of the driving motor 301a-1, and a driving gear ring 301a-3 meshing with it fixed on the outside of the rotating tube 301b.

[0047] The principle behind the rotation and lifting of the connecting plate 303a driven by the rotating assembly 301 is as follows: the drive motor 301a-1 drives the drive gear 301a-2 to rotate, which in turn drives the drive gear ring 301a-3 on the outside of the rotating tube 301b to rotate, causing the rotating tube 301b to rotate accordingly. Figure 3In the third state, the rotating tube 301b rotates, which drives the connecting plate 303a to rotate from the position near the end rod 303e toward the camera. When it rotates to above the camera, the notch 303g on the outside of the connecting plate 303a abuts against the other end rod 303e. At this time, the rotating tube 301b continues to rotate, while the connecting plate 303a is restricted due to the abutment of the end rod 303e. This restricts the connecting rod 302 fixed at the outer end of the connecting plate 303a, and it no longer rotates with the rotation of the rotating tube 301b. As a result, the threaded groove in the rotating tube 301b is threadedly connected to the threaded block 301c, causing the threaded block 301c to move down in the threaded groove, which drives the connecting rod 302 to move down, thereby causing the connecting plate 303a to move down and fasten the cleaning cap 303c to the outside of the camera.

[0048] When the camera needs to be exposed, the reverse rotation of the drive motor 301a-1 causes the rotating tube 301b to reverse. Under the action of the limiting rod 303f, the threaded block 301c in the connecting rod 302 moves upward in the threaded groove until it abuts against the abutment plate 301f. This causes the connecting plate 303a to move upward until it can disengage from the limiting rod 303f. At this time, the rotating tube 301b continues to rotate, causing the connecting plate 303a to drive the cleaning cap 303c to first disengage from the camera, then move away from the camera, and finally abut against the other end rod 303e, while simultaneously fastening onto the shielding plate 303c-2. Figure 3 As shown.

[0049] Example 2

[0050] Reference Figures 6-9 This is the second embodiment of the present invention. This embodiment provides a supplementary description of the first embodiment, which differs from the first embodiment in that it describes one implementation of the protective mechanism 200.

[0051] Specifically, the protective mechanism 200 includes a protective plate 201 and track bars 202 fixed to the top and bottom of the mounting frame 102. The two ends of the protective plate 201 are respectively inserted into the two track bars 202, and a connecting rod 203 is slidably inserted into one end of the protective plate 201. A limiting plate 204 adapted to the track bar 202 is fixed through the connecting rod 203. A tension spring 205 is sleeved on the outside of the connecting rod 203 and fixed to the outer end of the limiting plate 204 and the protective plate 201. A limiting block 206 that abuts against the limiting plate 204 is fixed inside the track bar 202. A pusher 207 for moving the protective plate 201 is installed inside the mounting frame 102. A lint board 208 for wiping the head and tail cameras 100 is fixed inside the protective plate 201. An opening 209 for the protective plate 201 to extend is provided on one side of the mounting frame 102.

[0052] The pusher 207 includes a pusher motor 207a fixed in the mounting frame 102. The output end of the pusher motor 207a is fixed with a rotating rod 207b that rotates and connects with the top of the mounting frame 102 via a coupling. Two toothed plates 207c are fixed on the inner side of the protective plate 201, and two pusher gears 207d are fixed on the outer side of the rotating rod 207b.

[0053] Operating principle of the protective mechanism 200: When the vehicle is passing or reversing, the rotation of the push motor 207a causes the rotating rod 207b and the push gear 207d to rotate synchronously, which in turn causes the meshing toothed plate 207c to move accordingly, opening the protective plate 201. Figures 7-9 As shown, it is in the open position, making it convenient for the camera to take pictures;

[0054] When not in a passing or reversing state, the push motor 207a reverses, causing the protective plate 201 to snap into place, closing the mounting frame 102 and preventing dust from being introduced and adhering to the outside of the camera. At the same time, the dust adhering to the outside of the camera can be removed by wiping the camera with the felt plate 208 on the inside of the protective plate 201.

[0055] Example 3

[0056] Refer to Figures 6-9 This is the third embodiment of the present invention. This embodiment provides supplementary explanations to the other embodiments. The difference between this embodiment and the other embodiments is the design of the inner support plate 207e of the mounting bracket 103.

[0057] Specifically, a support plate 207e is fixed to the inner side of the mounting bracket 103, and the support plate 207e is rotatably connected to the rotating rod 207b, and a protrusion that contacts the pile plate 208 is fixed to the outer end of the support plate 207e.

[0058] In this design, when the protective plate 201 opens, the corresponding pile plate 208 opens until the limiting plate 204 abuts against the limiting block 206. Figure 8 As shown, when the limiting plate 204 abuts against the limiting block 206, the pushing gear 207d engages with the toothed block at the end of the toothed plate 207c. As the pushing gear 207d continues to rotate, the toothed plate 207c disengages from it. Under the action of the tension spring 205, the protective plate 201 is pulled back a small distance. This cycle is repeated to achieve a reciprocating pulling action of the protective plate 201. It also allows the convex strip on the outer side of the support plate 207e to contact the plush board 208, shaking off the dust remaining on the plush board 208.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
