Description

Technical Field

[0001] The utility model relates to the technical field of unmanned mining trucks, in particular to a leakage-proof compartment and tailgate structure of an unmanned mining truck. Background Art

[0002] In recent years, with the continuous development of unmanned driving technology, this technology has gradually been applied to transportation in mining areas. The development of unmanned driving technology in mining areas has not only improved operational efficiency and reduced fuel and vehicle maintenance costs, but also reduced the risk of major safety accidents in mining areas. However, current unmanned mining trucks still have some technical shortcomings, such as insufficient sealing of the body and tailgate, deformation of the tailgate sealing surface after long-term use, and unevenness of the tailgate sealing surface, which leads to poor sealing performance. This has also led to leakage and dropping of materials when transporting slag and dust.

[0003] Typically, multiple unmanned mining trucks operate simultaneously within a mining area. To ensure that each unmanned mining truck can operate in an orderly manner within the mining area without collisions, it is necessary to rationally plan the operating speed of each mining truck under various road conditions within its respective operating section. This ensures that each unmanned mining truck avoids collisions and operates at the most economical speed. Therefore, each unmanned mining truck has a control module equipped with cameras, radar, and other equipment to monitor the real-time road conditions in the mining area. This information is fed back to the control module, which then analyzes and calculates the most economical operating speed for the unmanned mining truck under these road conditions.

[0004] Therefore, if unmanned mining trucks in the mining area are constantly leaking materials such as slag and dust, it will increase the dust in the mining area and affect the living environment around the mining area. Moreover, the leakage of slag and dust will cause the road conditions in the mining area to change, and the dust flying in the air will also cover the cameras and other information collection devices of other unmanned mining trucks, thereby affecting the unmanned mining trucks' judgment of real-time road conditions, increasing the complexity of the unmanned control terminal, and affecting the operational efficiency of the unmanned mining trucks.

[0005] Therefore, based on the above technical problems, technicians in this field urgently need to develop a leak-proof body and tailgate structure for unmanned mining trucks. Utility Model Content

[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] See also Figures 1 to 7 As shown;

[0042] The present embodiment provides a leak-proof compartment and tailgate structure for an unmanned mining truck, the structure comprising:

[0043] The sealing panel 1 is fixed to the rear of the carriage 100 and is fitted with the edge of the rear of the carriage 100 to form a sealing surface;

[0044] A tailgate sealing assembly 3, which is provided on the tailgate 200 of the mining truck and cooperates with the sealing panel 1 at the rear of the vehicle compartment 100; and

[0045] The material receiving assembly 2 is integrated into the lower part of the rear end of the carriage 100;

[0046] The sealing panel 1 and the tailgate sealing assembly 3 constitute a sealing structure between the tailgate 200 and the vehicle compartment 100 , and the material receiving assembly 2 is used to temporarily store slag and dust.

[0047] Specifically, this embodiment discloses a leakage-proof sealing structure integrated between the carriage 100 and the tailgate 200 of an unmanned mining truck; the structure mainly includes a sealing panel 1, a tailgate sealing assembly 3 and a material receiving assembly 2; wherein, the sealing panel 1 is fixed to the rear of the carriage 100, and the tailgate sealing assembly 3 is arranged on the tailgate 200, thereby forming a sealing structure between the tailgate 200 and the carriage 100 through the sealing panel 1 and the tailgate sealing assembly 3; at the same time, considering that some slag will leak and there is also the problem of flying dust, this embodiment also provides a material receiving assembly 2 for temporarily storing slag and dust at the lower part of the rear of the carriage 100.

[0048] Preferably, the sealing panel 1 of this embodiment is configured as a U-shaped plate structure that matches the rear edge of the carriage 100; more preferably, the sealing panel 1 of this embodiment is made of T700 high-strength steel.

[0049] First, in this embodiment, a high-strength sealing panel 1 formed as an integral piece is welded at the rear of the carriage 100 of the unmanned mining truck, and its sealing surface is processed by a mechanical processing technology to make this surface sufficiently smooth and flat; at the same time, the sealing surface at the rear of the carriage 100 is made of T700 high-strength steel, which has good structural strength, high hardness, and is not easy to deform, ensuring that the contact surface with the tailgate 200 is still well sealed after long-term use.

[0050] Preferably, the material receiving assembly 2 of this embodiment is configured as a U-shaped structure that matches the lower edge of the rear portion of the carriage 100;

[0051] One side of the material receiving assembly 2 is in contact with the lower edge of the rear end of the carriage 100 , and the other side of the material receiving assembly 2 extends toward the rear side of the carriage 100 to form a space between the rear end of the carriage 100 for storing slag and dust.

[0052] In this embodiment, the lower surface of the material receiving assembly 2 extends upwardly at an angle relative to the bottom surface of the carriage 100 .

[0053] The present embodiment also designs a material receiving assembly 2 at the lower part of the rear end of the car body 100. The material receiving assembly 2 is a temporary storage device for slag and dust of a U-shaped structure welded below the contact surface between the rear end of the unmanned mining truck car body 100 and the tailgate 200. The material receiving assembly 2 forms a certain angle α with the bottom surface of the car body 100, so that the whole vehicle will appear to be low in the front and high in the back. The sum of the whole vehicle posture angle and the angle α will enable the material receiving assembly 2 to accommodate a certain amount of slag and dust; when the vehicle passes through a bumpy road or a pothole section, a small amount of slag and dust may fall from the sealing between the tailgate 200 and the car body 100. This part of the slag and dust materials is temporarily stored in the material receiving assembly 2. When the mining truck arrives at the designated unloading location and the car body 100 is lifted to unload, the slag and dust in the material receiving assembly 2 will be unloaded together with the mineral material in the car body 100, thereby preventing the slag and dust from falling onto the road surface during the transportation of the mining truck.

[0054] In order to cooperate with the sealing panel 1 to form a sealed and leak-proof structure, the tailgate sealing assembly 3 of this embodiment includes a sealing pad 7 connected to the tailgate panel 6; and a sealing strip connected to the sealing pad 7;

[0055] The sealing pad 7 and the sealing strip of this embodiment are both assembled and fixed to the tailgate panel 6 via fasteners.

[0056] More preferably, the sealing member of this embodiment includes a pre-welded nut 5 welded and fixed to the tailgate panel 6 ; and a connecting bolt threadedly connected to the pre-welded nut 5 and passing through the sealing strip, the sealing pad 7 and the tailgate panel 6 .

[0057] The above-mentioned sealing strip adopts a double-peak sealing strip 8, and the middle part of the double-peak sealing strip 8 is formed into an embedded groove;

[0058] A sealing strip pressing plate 9 is provided in the embedding groove of the sealing strip, and a flat washer 10 is provided between the connecting bolt 4 and the sealing strip pressing plate 9 .

[0059] The sealing pad 7 of this embodiment is made of T700 high-strength steel that is formed in one piece. It has good flatness and is connected to the tailgate panel 6 through connecting bolts 4 without going through welding or other processes. A double-peak sealing strip 8 is designed to ensure sealing. When the double-peak sealing strip 8 is aged or damaged, it is easy to remove and replace.

[0060] When the sealing panel 1, material receiving assembly 2 and tailgate sealing assembly 3 of this embodiment work together, they effectively solve the problem of leakage and falling of materials such as slag and dust during transportation caused by poor flatness of the sealing surface at the rear of the vehicle body 100 and the volatility of the tailgate sealing plate, and avoid the problem of increased complexity in processing real-time road condition information of vehicles in the mining area due to changes in road conditions in the mining area.

[0061] In the above technical solution, the utility model provides a leak-proof compartment and tailgate structure for an unmanned mining truck, which has the following beneficial effects:

[0062] The leak-proof compartment and tailgate structure of the utility model improve the sealing performance of the mining truck, avoid the leakage of slag and the flying of dust, ensure that the mining truck can stably identify the operating road conditions, and also improve the mining environment and reduce the pollution of the mining operation to the surrounding environment.

[0063] The utility model welds a T700 high-strength sealing panel 1 at the rear of the carriage 100 and installs a T700 high-strength sealing pad 7 on the tailgate panel 6, ensuring that the sealing surface between the tailgate 200 and the rear of the carriage 100 will not be easily deformed, thereby improving the stability of the sealing performance of the mining truck.

[0064] The sealing member of the utility model adopts a double-peak sealing strip 8, which has double sealing and double protection, and is assembled in the form of a fastener, which is convenient for replacement and maintenance when the sealing strip is aged or damaged.

[0065] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
