Description
Technical Field
[0001] This utility model belongs to the field of dump truck technology, specifically a mining truck cargo box anti-stick plate installation structure. Background Technology
[0002] Dump trucks, also known as mining dump trucks, are a type of off-highway dump truck used in off-highway field locations such as large open-pit mines and water conservancy projects to transport materials such as coal and sand. Dump trucks typically have a strong heavy-duty capacity, capable of carrying several tons to tens of tons or even more of material, meeting the heavy-duty transportation needs in harsh environments such as mines. Dump trucks are widely used in the mining of coal and metals to transport mined materials such as coal and ore from the mining site to areas outside the mine for subsequent processing and transshipment.
[0003] In mining environments with high humidity, the working face becomes muddy and the ore material is highly viscous, easily adhering to the inner walls of the mine car's cargo box, especially at the bottom. This severely hinders subsequent material unloading and significantly reduces operational efficiency. Currently, anti-sticking plates made of polymer materials are often used to line the inside of the mine car's cargo box to reduce material adhesion. However, current anti-sticking plate installation methods have significant drawbacks: during loading, material impacts can easily loosen the anti-sticking plate connections; the edges of the anti-sticking plates are prone to damage after impacts from heavy objects; and material can easily seep into the gaps between the anti-sticking plate and the cargo box panels, compromising the connection stability and thus affecting its anti-sticking effect and service life. Utility Model Content
[0004] To address the problem that the anti-sticking plates inside the mine car bed are prone to damage, detachment, and separation after repeated impacts, this utility model provides an anti-sticking plate installation structure for the mine car cargo box.
[0005] This utility model is achieved through the following technical solution:
[0006] A mining car cargo box anti-sticking plate installation structure includes a car bucket. A bottom anti-sticking plate, side anti-sticking plates, and a front anti-sticking plate are respectively installed on the bottom surface, two inner side walls, and a front inner side wall of the car bucket. The bottom anti-sticking plate has evenly distributed fixing holes. The inner wall of the car bucket is provided with threaded seats corresponding to the fixing holes. Locking bolts, threaded to the threaded seats, are installed in the fixing holes and press the bottom anti-sticking plate onto the car bucket. Sealing strips are provided at the edges of the bottom anti-sticking plate and the car bucket. The side anti-sticking plates and the front anti-sticking plate are fixed to the car bucket in the same way as the bottom anti-sticking plate.
[0007] The gap between the anti-stick plate and the truck bed is filled with a sealing strip, which helps to prevent broken material particles from entering between the anti-stick plate and the truck bed. The anti-stick plate is installed on the truck bed by locking bolts arranged in a matrix, which helps to increase the density of locking points and improve the impact resistance to bumps during the loading of materials into the truck bed. The evenly distributed locking points and sealing strips help to improve the connection stability of the anti-stick plate on the truck bed and extend the service life of the anti-stick plate.
[0008] A further improvement of this utility model is that the aforementioned fixed circular hole is a countersunk hole structure, wherein the diameter of the large hole of the countersunk hole structure is larger than the diameter of the nut of the locking bolt, and the diameter of the small hole is smaller than the diameter of the nut of the locking bolt.
[0009] A further improvement of this invention is that a ring-shaped locking pressure plate is provided on the stepped surface of the aforementioned fixing hole, which can contact the bottom surface of the nut of the locking bolt. The locking bolt, through the fixing hole of the countersunk hole structure and in conjunction with the locking pressure plate, constructs a stable anti-stick plate fixing system, enhancing the tightness of the connection, helping to ensure the high accuracy of the anti-stick plate installation and positioning, and effectively resisting the risk of external impact and displacement during operation.
[0010] A further improvement of this utility model is that the rear of the aforementioned truck bed is also provided with an inclined section; the inclined section is provided with a rear anti-stick plate installed in the same manner as the bottom anti-stick plate. The inclined section forms a slope to prevent materials from falling, and at the same time, the rear anti-stick plate is installed on it to prevent materials from adhering during the falling process.
[0011] A further improvement of this invention is that the density of the fixing holes on the rear anti-stick plate is greater than the density of the fixing holes on the bottom anti-stick plate. Since the rear anti-stick plate is a critical area subjected to material impact and significant shear loads during the unloading stage, increasing the distribution density of the mounting holes in the anti-stick plate strengthens and reinforces it, significantly improving the structural stability and impact resistance of the rear anti-stick plate and ensuring reliable anti-sticking performance under complex stress environments.
[0012] A further improvement of this utility model is that the aforementioned bottom anti-stick plate, side anti-stick plate, and rear anti-stick plate are also provided with fixing elongated holes covering at least two threaded seats installed on the inner wall of the truck bed; the fixing elongated holes are provided with steps, and elongated locking pressure plates are placed on the steps. The locking pressure plates are provided with through holes corresponding to the covered threaded seats, and locking bolts that are threaded to the threaded seats and press the locking pressure plates are passed through the through holes. The locking bolts, through the steps of the fixing elongated holes and in conjunction with the elongated locking pressure plates, form a stable anti-stick plate fixing system, enhancing the tightness of the connection, helping to ensure high accuracy of anti-stick plate installation and positioning, and effectively resisting external impacts and displacement risks during operation.
[0013] A further improvement of this utility model is that a bottom plate anti-sticking plate is provided between the bottom plate anti-sticking plate and the side plate anti-sticking plate, which is installed on the truck bed and is inclined.
[0014] A further improvement of this utility model is that a front plate inclined guide anti-stick plate is provided between the aforementioned bottom plate anti-stick plate and front plate anti-stick plate, which is installed on the truck bed and is inclined.
[0015] A further improvement of this utility model is that a reinforcing anti-stick plate is provided between the aforementioned front anti-stick plate and side anti-stick plate, and is installed on the truck bed. By placing the reinforcing anti-stick plate between the front and side anti-stick plates, dead corners for material accumulation are avoided.
[0016] A further improvement of this utility model is that a rear-side guide anti-stick plate, installed on the truck bed, is provided between the aforementioned rear anti-stick plate and the side anti-stick plate. This facilitates material unloading.
[0017] As can be seen from the above technical solution, the beneficial effects of this utility model are: the gap between the anti-stick plate and the truck bed is filled with a sealing strip, which helps to prevent broken material particles from entering between the anti-stick plate and the truck bed; the anti-stick plate is installed on the truck bed by locking bolts arranged in a matrix, which helps to increase the density of locking points and improve the impact resistance to bumps during the loading of materials into the truck bed; the evenly distributed locking points and sealing strips help to improve the connection stability of the anti-stick plate on the truck bed and extend the service life of the anti-stick plate.

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0026] Example 1:
[0027] like Figure 1 , 2 As shown in Figures 3 and 5, this utility model discloses an anti-sticking plate installation structure for a mine car cargo box, including a car bed 10. A bottom anti-sticking plate 20, a side anti-sticking plate 30, and a front anti-sticking plate 40 are respectively installed on the bottom surface, two inner side walls, and the front inner side wall of the car bed 10. The bottom anti-sticking plate 20 has evenly distributed fixing holes 21. The inner wall of the car bed 10 is provided with threaded seats 12 corresponding to the fixing holes 21. Locking bolts 24 are threaded into the fixing holes 21 and threadedly connected to the threaded seats 12, pressing the bottom anti-sticking plate 20 onto the car bed 10. Sealing strips 70 are provided at the edges of the bottom anti-sticking plate 20 and the car bed 10. The fixing methods of the side anti-sticking plates 30 and the front anti-sticking plate 40 on the car bed 10 are the same as the fixing methods of the bottom anti-sticking plate 20 on the car bed 10. The gap between the anti-stick plate and the hopper 10 is filled with a sealing strip 70, which helps to prevent broken material particles from entering between the anti-stick plate and the hopper 10. The anti-stick plate is installed on the hopper 10 by locking bolts 24 arranged in a matrix, which helps to increase the density of locking points and improve the impact resistance to bumps during the loading of materials into the hopper 10. The evenly distributed locking points and the sealing strip 70 help to improve the connection stability of the anti-stick plate on the hopper 10 and extend the service life of the anti-stick plate.
[0028] The fixing hole 21 is a countersunk hole structure. The diameter of the larger hole is larger than the diameter of the nut of the locking bolt 24, and the diameter of the smaller hole is smaller than the diameter of the nut of the locking bolt 24. A ring-shaped locking plate 23 is provided on the stepped surface of the fixing hole 21, which can contact the bottom surface of the nut of the locking bolt 24. The locking bolt 24, through the fixing hole 21 of the countersunk hole structure and in conjunction with the locking plate 23, forms a stable anti-stick plate fixing system, enhancing the tightness of the connection and helping to ensure high-precision installation and positioning of the anti-stick plate, effectively resisting external impacts and displacement risks during operation.
[0029] The rear of the truck bed 10 is also provided with an inclined section 11; the inclined section 11 is provided with a rear anti-stick plate 80 installed in the same manner as the bottom anti-stick plate 20. The inclined section 11 forms a slope to prevent materials from falling, and at the same time, the rear anti-stick plate 80 is installed on it to prevent materials from adhering during the falling process.
[0030] The density of the fixing holes 21 on the rear anti-stick plate 80 is greater than the density of the fixing holes 21 on the bottom anti-stick plate 20. Since the rear anti-stick plate 80 is a critical area that bears material impact and large shear load during the unloading stage, the reinforcement measures implemented by increasing the distribution density of the anti-stick plate mounting holes significantly improve the structural stability and impact resistance of the rear anti-stick plate 80, ensuring reliable anti-sticking effect under complex stress environments.
[0031] Example 2:
[0032] like Figure 1-5 As shown, the bottom anti-stick plate 20, side anti-stick plate 30, and rear anti-stick plate 80 are also provided with at least two fixing elongated holes 22 covering at least two threaded seats 12 installed on the inner wall of the truck bed 10. At least two fixing elongated holes 22 are provided on the same anti-stick plate. A step is provided within each fixing elongated hole 22, and a long strip-shaped locking pressure plate 25 is placed on this step. The locking pressure plate 25 has a through hole corresponding to the covering threaded seat 12. A locking bolt 24, threaded to the threaded seat 12 and pressing against the locking pressure plate 25, can pass through this through hole. The locking bolt 24, through the step of the fixing elongated hole 22 and in conjunction with the long strip-shaped locking pressure plate 25, constructs a stable anti-stick plate fixing system, enhancing the tightness of the connection and helping to ensure high-precision installation and positioning of the anti-stick plate, effectively resisting external impacts and displacement risks during operation.
[0033] The length direction of the fixed elongated hole 22 is consistent with the front-rear direction of the truck bed 10, and the fixed elongated hole 22 is evenly distributed on the anti-stick plate. The fixed elongated hole 22 is surrounded by a fixed circular hole 21.
[0034] The fixed elongated hole 22 can be obtained by machining at least two adjacent fixed circular holes 21 through each other.
[0035] Example 3:
[0036] like Figure 1-3 As shown, a bottom plate anti-stick plate 20 and a side plate anti-stick plate 30 are provided between them. The bottom plate side guide anti-stick plate 31 is installed on the truck bed 10 and is inclined.
[0037] Between the bottom plate anti-stick plate 20 and the front plate anti-stick plate 40, there is a front plate inclined guide anti-stick plate 41 installed on the truck bed 10 and arranged in an inclined position.
[0038] A rear-side anti-sticking plate 81, installed on the truck bed 10, is provided between the rear anti-sticking plate 80 and the side anti-sticking plate 30. This facilitates material unloading.
