Description

Technical Field

[0001] This utility model relates to the field of antenna installation equipment. More specifically, this utility model relates to an antenna bracket and an unmanned off-highway dump truck. Background Technology

[0002] Off-highway dump trucks are key equipment in open-pit coal mines, cement and building material mines, sand and gravel aggregate mines, metal and non-metal mines, water conservancy and hydropower projects, and large-scale engineering projects. They are characterized by high loading and unloading capacity, heavy load capacity, short transport distance, and long continuous working time. Off-highway dump trucks often travel on winding, potholed roads, with worse road conditions and greater vibrations compared to on-highway dump trucks. Currently, the antennas of unmanned off-highway dump trucks are mounted on the top of the cab. However, to prevent the cab from being hit by falling debris, the cargo box hood of off-highway dump trucks often extends above the cab, thus obstructing the antenna signal.

[0003] In existing technology, an antenna bracket is installed on the top of the cab to raise the antenna's installation height, ensuring it is not affected by the cargo box hood when receiving signals. Currently, off-highway dump truck antenna brackets are mainly made of bent and welded steel plates. This structure is simple to manufacture, but it is heavy, has poor reliability, and is prone to cracking and breakage during long-term use. This can lead to unmanned off-highway dump trucks being unable to receive signals, causing vehicle malfunctions and affecting production efficiency. Utility Model Content

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0029] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0030] like Figure 1-3 As shown, this utility model provides an antenna bracket for an unmanned off-highway dump truck, including a mounting plate 6, two pairs of mounting seats, a pair of front diagonal braces 1, a pair of rear diagonal braces 3, and a pair of rear braces 5. The two pairs of mounting seats are located below the mounting plate 6. Each pair of mounting seats is spaced apart along the length of the mounting plate 6, and the two pairs of mounting seats are spaced apart along the width of the mounting plate 6.

[0031] The pair of front diagonal braces 1, the pair of rear diagonal braces 3, and the pair of rear braces 5 correspond one-to-one and are all in a figure-eight shape;

[0032] Both the pair of front diagonal braces 1 and the pair of rear diagonal braces 3 are inclined forward. The large ends of the pair of front diagonal braces 1 are connected to the two ends of the bottom of the mounting plate 6 near its length, and the small ends are connected to the pair of mounting seats near the mounting plate 6.

[0033] The small ends of the pair of rear support rods 5 are respectively connected to the two sides of the bottom center of the mounting plate 6, and the large ends are respectively connected to the other pair of mounting seats.

[0034] The top end of the pair of rear diagonal braces 3 is connected to the corresponding front diagonal brace 1 near its top, and the bottom end is connected to the lower part of the corresponding rear brace 5.

[0035] In the above technical solution, the mounting plate 6 is a steel plate with antenna mounting holes for mounting antennas; two pairs of identical mounting seats are provided below the mounting plate 6. In each pair of mounting seats, the two mounting seats are spaced apart along the length of the mounting plate 6. The two pairs of mounting seats are a pair of front mounting seats 11 and a pair of rear mounting seats 7. Along the width of the mounting plate 6, the pair of front mounting seats 11 and the pair of rear mounting seats 7 are spaced apart, and the pair of front mounting seats 11 are closer to the mounting plate 6 than the pair of rear mounting seats 7.

[0036] A pair of forward-inclined front braces 1 are provided between the mounting plate 6 and the pair of front mounting seats 11. The pair of front braces 1 are V-shaped, with the top ends of the front braces 1 being larger ends, which are respectively connected to the bottom of the mounting plate 6 near its length. The bottom ends of the front braces 1 are smaller ends, which are respectively connected to the pair of front mounting seats. The connection between the front braces 1 and the bottom of the mounting plate 6 is detachable, preferably screwed. It should be noted that... Figure 1 As shown, the forward tilt of the front diagonal brace 1 means that, along the width direction of the mounting plate 6, the top of the front diagonal brace 1 tilts toward the side away from the pair of rear mounting seats 7, and the angle between the front diagonal brace 1 and the horizontal plane is preferably 45 to 90 degrees.

[0037] A pair of forward-inclined rear support rods 5 are provided between the mounting plate 6 and the pair of rear mounting seats 7. The pair of rear support rods 5 are V-shaped, with the bottom ends of the rear support rods 5 being larger ends, which are respectively connected to the pair of rear mounting seats 7. The top ends of the pair of rear support rods 5 are smaller ends, which are respectively connected to both sides of the bottom center of the mounting plate 6, preferably near the bottom center. The connection between the rear support rods 5 and the bottom of the mounting plate 6 is detachable, preferably screwed. It should be noted that... Figure 1 As shown, the forward tilt of the rear support rod 5 means that, along the width direction of the mounting plate 6, the top of the rear support rod 5 tilts toward the side closer to the pair of front mounting seats 11.

[0038] It also includes a pair of rear diagonal braces 3, a pair of front diagonal braces 1, and a pair of rear braces 5, which correspond one-to-one. The rear diagonal braces 3 are located between the corresponding front diagonal braces 1 and the rear braces 5. The rear diagonal braces 3 are inclined forward. The end of the rear diagonal brace 3 at the height is connected to the upper part of the corresponding front diagonal brace 1, preferably connected to the corresponding front diagonal brace 1 near the top. The end of the rear diagonal brace 3 at the lower part is connected to the lower part of the corresponding rear brace 5, so that an acute angle is formed between the front diagonal brace 1 and the rear diagonal brace 3. It should be noted that the forward inclination of the rear diagonal brace 3 means that along the width direction of the mounting plate 6, the top of the rear diagonal brace 3 is inclined toward the side closer to the pair of front mounting seats 11.

[0039] The rear diagonal brace 3, the front diagonal brace 1, and the rear brace 5 can be hollow round tubes, hollow square tubes, or reinforcing bars. It should be noted that the spacing between the two mounting seats in a pair of front mounting seats 11 and the spacing between the two mounting seats in a pair of rear mounting seats 7 may not be the same. Figures 1-2 As shown, the spacing between the two mounting seats of a pair of front mounting seats 11 is smaller, while the spacing between the two mounting seats of a pair of rear mounting seats 7 is larger.

[0040] In this technical solution, during use, firstly, a pair of front diagonal braces 1 are installed on a pair of front mounting seats 11, a pair of rear braces 5 are installed on a pair of rear mounting seats 7, and rear diagonal braces 3 are installed between the corresponding front diagonal braces 1 and rear braces 5. Then, the mounting plate 6 is installed on the top of the pair of front diagonal braces 1 and the pair of rear braces 5, thus completing the assembly of the antenna bracket. Then, a pair of front mounting seats 11 and a pair of rear mounting seats 7 are installed on the top of the cab. The installation positions of the front mounting seats 11 and the rear mounting seats 7 are: the front mounting seats 11 and the rear mounting seats 7 are spaced apart along the length direction of the vehicle's main frame (also along the width direction of the mounting plate 6), with the rear mounting seats 7 located closer to the cargo box.

[0041] The beneficial effects of adopting this technical solution are as follows: by setting up a mounting plate 6, a pair of front mounting seats 11, a pair of rear mounting seats 7, a pair of front diagonal braces 1, a pair of rear diagonal braces 3, and a pair of rear braces 5, an antenna support structure is provided. The overall structure of this antenna support is "higher in the front and lower in the back," providing a higher position for antenna installation so that it is not affected by the cargo box hood when receiving signals. At the same time, the front diagonal braces 1, rear braces 5, and rear diagonal braces 3 form a triangle, which improves the overall torsional strength. In addition, compared with the bent steel plates in the prior art, the front diagonal braces 1, rear diagonal braces 3, and rear braces 5 of this utility model are hollow round tubes or hollow square tubes, which can greatly reduce the overall weight of the antenna support. Overall, the antenna support of this utility model is lighter, has high overall torsional strength, is not easy to break, and has good reliability.

[0042] In another technical solution, a pair of figure-eight shaped mounting rods 2 are also included. The small ends of the pair of mounting rods 2 are respectively connected to the two sides of the bottom center of the mounting plate 6, and the large ends are respectively connected to the upper part of the pair of front diagonal braces 1. The small ends of the pair of rear braces 5 are respectively connected to the pair of mounting rods 2, so as to be connected to the mounting plate 6 through the mounting rods 2.

[0043] In the above technical solution, the antenna bracket also includes a pair of mounting rods 2, which are V-shaped and located between a pair of front diagonal braces 1. The top of the pair of mounting rods 2 is a small opening, and the small opening of each pair of mounting rods 2 is connected to the bottom of the mounting plate 6. Preferably, the connection is close to the middle of the bottom of the mounting plate 6. The bottom of the pair of mounting rods 2 is a large opening, and the large opening of each pair of mounting rods 2 is connected to the upper part of the pair of front diagonal braces 1. A pair of rear support rods 5 correspond one-to-one with the pair of mounting rods 2. The small opening of each pair of rear support rods 5 is connected to the pair of mounting rods 2, so that the rear support rods 5 are connected to the mounting plate 6 through the mounting rods 2. Preferably, the small opening of each pair of rear support rods 5 is connected to the upper part of the pair of mounting rods 2.

[0044] The beneficial effect of adopting this technical solution is that by setting the mounting rod 2, the connection strength between the front diagonal brace 1 and the mounting plate 6 is further strengthened, and an installation point is provided for the installation of the rear brace 5, which facilitates the installation of the rear brace 5.

[0045] In another technical solution, a front crossbar 4 is also included. The front crossbar 4 is arranged along the length of the mounting plate 6. Both ends of the front crossbar 4 are respectively connected to the pair of mounting rods 2. The small ends of the pair of rear support rods 5 are respectively connected to the front crossbar 4. Specifically, the front crossbar 4 is located between the pair of mounting rods 2. The front crossbar 4 is arranged along the length of the mounting plate 6. Both ends of the front crossbar 4 are respectively connected to the pair of mounting rods 2, and the connection point does not exceed one-third of the length of the front diagonal support rod 1. That is, in the length direction of the mounting rod 2 from its bottom end to its top end, the connection point between the mounting rod 2 and the front crossbar 4 does not exceed two-thirds of the length of the mounting rod 2 (the small ends of the pair of rear support rods 5 are respectively connected to the two sides of the middle of the front crossbar 4, so that the rear support rods 5 are connected to the mounting plate 6 through the front crossbar 4 and the mounting rods 2).

[0046] The beneficial effects of adopting this technical solution are that by setting the front crossbar 4, a new way of connecting the rear support rod 5 and the mounting plate 6 is provided. The front crossbar 4 connects a pair of mounting rods 2, which further improves the connection strength of the overall device. At the same time, the setting of the front crossbar 4 facilitates the installation of the rear support rod 5.

[0047] In another technical solution, a rear crossbar 8 is also included. The rear crossbar 8 is arranged along the length direction of the mounting plate 6, and both ends of the rear crossbar 8 are respectively connected to the pair of rear support rods 5. Specifically, the connection point between the rear crossbar 8 and the rear support rod 5 is higher than the connection point between the rear diagonal brace 3 and the rear support rod 5. At the same time, the connection point between the rear crossbar 8 and the rear support rod 5 does not exceed one-quarter of the length of the rear support rod 5. That is, in the length direction of the rear support rod 5 from its bottom end to its top end, the part of the rear support rod 5 that connects to the rear crossbar 8 does not exceed three-quarters of the length of the rear support rod 5.

[0048] The beneficial effect of adopting this technical solution is that by designing the rear crossbar 8, which connects to a pair of rear support rods 5, the connection strength of the device is further improved, thereby enhancing the overall torsional and anti-tipping performance of the device.

[0049] In another technical solution, the front diagonal brace 1, the rear diagonal brace 3, the rear brace 5, the front crossbar 4, and the rear crossbar 8 are all hollow circular tubes. The beneficial effects of adopting this technical solution are that, on the one hand, the hollow circular tube design is lighter in weight, which can greatly reduce the overall weight of the antenna support compared to the bent steel plate in the prior art; on the other hand, due to the symmetry of its cross-sectional shape, the symmetry of the circular tube reduces stress concentration on the cross-section, and the force distribution is more uniform when the circular tube is subjected to torque, thus better resisting torsion.

[0050] In another technical solution, the mounting base includes a base plate 701, a reinforcing rib 702, and a reinforcing tube 703. The base plate 701 has a circular hole 704 in the middle and mounting screw holes at each of the four corners. The reinforcing tube 703 is disposed on the top surface of the base plate 701 and is coaxial with the circular hole 704.

[0051] In this technical solution, each mounting base includes a base plate 701, a reinforcing rib 702, and a reinforcing tube 703. The base plate 701 has mounting screw holes at all four corners for mounting the base plate 701 on the top of the cab. A circular hole 704 is provided through the center of the base plate 701. The reinforcing tube 703 is vertically arranged on the top surface of the base plate 701, and the reinforcing tube 703 is coaxial with the circular hole 704. The beneficial effect of adopting this technical solution is that it provides a mounting base structure that is easy to assemble and install, and at the same time has high structural strength.

[0052] In another technical solution, both the front diagonal brace 1 and the rear brace 5 include an inclined section 9 and a vertical section 10 that are connected by a transition. The bottom of the vertical section 10 is inserted into the corresponding reinforcing tube 703. The circular hole 704 between the bottom of the vertical section 10 and the bottom surface of the substrate 701 forms a welding hole.

[0053] In the above technical solution, both the front diagonal brace 1 and the rear brace 5 include a forward-inclined section 9 and a vertical section 10 that is arc-connected to the inclined section 9. The vertical section 10 is coaxially inserted into the corresponding reinforcing tube 703, and the bottom of the vertical section 10 extends into the corresponding circular hole 704. There is a certain distance between the bottom of the vertical section 10 and the bottom surface of the substrate 701, so that the circular hole 704 located between the vertical section 10 and the bottom surface of the substrate 701 forms a welding hole.

[0054] In this technical solution, during use, the reinforcing tube 703 is first welded to the substrate 701, and then the vertical sections 10 of the front diagonal brace 1 and the rear brace 5 are inserted into the corresponding reinforcing tube 703. Solder is filled into the corresponding welding holes and welded so that the front diagonal brace 1 and the rear brace 5 can be installed on the corresponding mounting base.

[0055] The beneficial effects of adopting this technical solution are that by setting up the base plate 701, the reinforcing tube 703, the vertical section 10 and the inclined section 9, a structure for a mounting base and the front inclined support rod 1 and the rear inclined support rod 5 is provided. On the one hand, the installation strength between the mounting base and the cab is strengthened, and on the other hand, the design of the reinforcing tube 703 facilitates the installation of the rear support rod 5 and the front inclined support rod 1, resulting in good performance.

[0056] In another technical solution, the reinforcing rib 702 is a near-right triangle, and the right-angled sides of the reinforcing rib 702 are respectively connected to the top surface of the reinforcing tube 703 and the base plate 701. Specifically, there are four reinforcing ribs 702, which are evenly spaced along the circumference of the reinforcing tube 703. The reinforcing rib 702 is a near-triangular shape, and its two side walls where the right-angled sides are located are respectively connected to the reinforcing tube 703 and the base plate 701. In use, the two right-angled sides of the four reinforcing ribs 702 are respectively welded to the corresponding reinforcing tube 703 and base plate 701 to strengthen the connection strength between the base plate 701 and the reinforcing tube 703, thereby indirectly improving the installation strength between the mounting base and the top of the cab.

[0057] In another technical solution, the inclined surface of the reinforcing rib 702 is a concave arc surface; the beneficial effect of adopting this technical solution is that by designing the inclined surface of the reinforcing rib 702 as a concave arc surface, the concave arc surface can eliminate the abrupt stress of the traditional planar angle, and further improve the reinforcing effect of the reinforcing rib 702.

[0058] In another technical solution, the mounting plate 6 is provided with a headlight mounting hole; the beneficial effect of this technical solution is that it facilitates the installation of headlights by providing a headlight mounting hole.

[0059] In another technical solution, the mounting plate 6 is provided with weight-reducing holes; the beneficial effect of adopting this technical solution is that by providing weight-reducing holes, the weight of the mounting plate 6 is reduced, further reducing the weight of the overall device, and avoiding the overall device from being too heavy and easily tipping over and becoming unstable.

[0060] In another technical solution, the mounting plate 6 is folded down along both sides of its length to form reinforcing edges. Specifically, as shown in the figure, the mounting plate 6 is folded down along both sides of its length, and the folded parts form reinforcing edges, which mainly serve to strengthen the mounting plate 6.

[0061] An unmanned off-highway dump truck includes the aforementioned antenna bracket. Compared with the bent steel plate in the prior art, the antenna bracket is lighter, has higher overall torsional strength, is less prone to breakage, and has better reliability. This indirectly makes the unmanned off-highway dump truck more stable and effective in use, and minimizes the need for frequent shutdowns and repairs due to antenna bracket damage.

[0062] The number of devices and processing scale described herein are for the purpose of simplifying the description of this utility model. Applications, modifications, and variations of the antenna bracket for the unmanned off-highway dump truck of this utility model will be readily apparent to those skilled in the art.

[0063] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
