Description

Technical Field

[0001] This utility model relates to the field of mechanical connection technology, and more specifically, it relates to a connection mechanism for mining dump trucks. Background Technology

[0002] The cargo box of a mining dump truck is one of its core components, primarily used for loading and transporting materials such as ore. The cargo box is typically made of high-strength steel, featuring a robust structure and excellent wear resistance, capable of withstanding heavy loads and harsh working conditions. Its design emphasizes both load-bearing capacity and lightweight construction; through optimized structure and material selection, sufficient strength is ensured while reducing weight, thus improving transportation efficiency. The cargo box typically employs a center-top, rear-discharge design, equipped with a hydraulic lifting system, enabling rapid and efficient unloading operations.

[0003] Currently, the upper mounting surface of the tipping support of the mining dump truck is fixed to the cargo box with bolts, and the mounting hole on the lower side of the tipping support is hinged to the mounting hole on the frame with a pin. After the tipping support is fixed to the cargo box, it rotates relative to the frame around the pin under the action of the lifting cylinder on the front side of the cargo box.

[0004] However, in actual working conditions, when the threaded groove of the threaded mounting plate on the connecting body is damaged, the entire connecting body needs to be disassembled and repaired. This requires difficult operations such as air gouging, welding, and repositioning on the construction site, resulting in slow replacement progress and the inability to carry out rapid repairs.

[0005] Therefore, this utility model proposes a connecting mechanism for mining dump trucks. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a connection mechanism for mining dump trucks.

The connecting body also has symmetrically arranged connecting holes. The positions of the two limiting components are restricted by the multiple first limiting blocks and second limiting blocks. The limiting component includes a threaded mounting plate with multiple threaded grooves. The tilting support component includes a tilting body with multiple positioning holes arranged on both sides of the tilting body. The threaded grooves, connecting holes, and positioning holes are fixed together by fixing components.

[0009] The present invention is further configured such that: the connecting mechanism further includes a fixed seat, the lower part of which is fixedly installed on the upper surface of the connecting body; the first limiting block restricts the lateral movement distance of the threaded mounting plate; and the second limiting block restricts the longitudinal movement distance of the threaded mounting plate.

[0010] The present invention is further configured such that: the fixing component includes a bolt and a washer, and after the washer is fitted onto the bolt, it passes through the positioning hole and the connecting hole and is fixed with the threaded groove.

[0011] The present invention is further configured such that: a flip fixing plate is symmetrically arranged below the flipping body, and a rotating groove is provided on both flip fixing plates.

[0012] The present invention is further configured such that: a fastener is installed on the outer wall of one of the flip-fixing plates, and a pin assembly is rotatably provided on the flip-fixing plate.

[0013] The present invention is further configured such that: the pin assembly includes a rotating shaft, the rotating shaft is rotatably disposed in two rotating grooves, and a special-shaped part is installed on the part of the rotating shaft outside the flip-fixed plate.

[0014] The present invention is further configured such that the irregularly shaped part is fixed in a fastener.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] Example 1, please refer to Figures 1-6 The present invention provides the following technical solution:

[0029] See Figures 1-3A mining dump truck includes a cargo box assembly 1 and a connecting mechanism 2. The cargo box assembly 1 includes a cargo box body 11. Four fixing frames 12 are equidistantly arranged below the cargo box body 11. The four fixing frames 12 are divided into two groups, and a fixing groove 13 is provided in the middle of each group of fixing frames 12.

[0030] The cargo box assembly 1 is used for overall loading and unloading. The cargo box body 11 is the main body for loading and unloading. The fixing frame 12 improves the support stability of the cargo box body 11 and provides the conditions and position for setting the fixing groove 13. The fixing groove 13 provides the installation position for the connecting mechanism 2.

[0031] See Figures 4-6 A connecting mechanism 2 for a mining dump truck also includes a fixed seat 21, the upper end of which is fixed to the bottom of the cargo box body 11, and the two sides of the fixed seat 21 are respectively fixed to the sides of two fixed frames 12.

[0032] The fixing seat 21 is used for fixing. The fixing seat 21 is H-shaped. The upper surface of the fixing seat 21 is welded to the lower surface of the cargo box body 11. The two fixing seats 21 are pressed and fixed by the two sides of the fixing frame 12, so that the fixing seat 21 is installed more stably and avoids falling off.

[0033] The aforementioned connecting mechanism 2 includes a connecting component 23, a limiting component 22 disposed above the connecting component 23, a flip support component 24 disposed below the connecting component 23, and multiple fixing components 26. The limiting components 22 are symmetrically disposed above the connecting component 23. The connecting component 23 includes a connecting body 231. Multiple first limiting blocks 232 and second limiting blocks 233 are disposed on both sides of the upper part of the connecting body 231. Connecting holes 234 are also symmetrically disposed on the connecting body 231. The positions of the two limiting components 22 are restricted by the multiple first limiting blocks 232 and second limiting blocks 233. The limiting component 22 includes a threaded mounting plate 221. Multiple threaded grooves 222 are disposed on the threaded mounting plate 221. The flip support component 24 includes a flipping body 241. Multiple positioning holes 245 are disposed on both sides of the flipping body 241. The threaded grooves 222, connecting holes 234, and positioning holes 245 are fixed together by the fixing components 26.

[0034] The through hole on the connecting component 23 is aligned with the through hole of the fixing base 21. The upper surface of the connecting component 23 is fixed to the lower surface of the fixing base 21. The fixing component 26 fixes the limiting component 22, the connecting component 23 and the flip support component 24 together. The first limiting block 232 and the second limiting block 233 form two rectangles on both sides of the upper surface of the connecting body 231. The size of the rectangles is set to match the size of the limiting component 22. When the limiting component 22 is placed, it can be directly aligned with the position of the thread groove 222 and the second limiting block 233 to avoid misalignment. The connecting holes 234 are all set in the rectangle formed by the first limiting block 232 and the second limiting block 233. The upper surface of the flip body 241 is in contact with the upper surface of the connecting body 231. The position of the positioning hole 245 is aligned with the position of the connecting hole 234 and the thread groove 222.

[0035] By providing a connection hole 234 on the mounting surface of the connecting body 231, and providing threaded grooves 222 on both threaded mounting plates 221 for fixing the fixing component 26, when the threaded grooves 222 on the threaded mounting plate 221 are damaged, the fixing component 26 can be removed, and then the damaged threaded mounting plate 221 can be taken out and replaced with a new threaded mounting plate 221, thus achieving the effect of quickly replacing the threaded mounting plate 221 for repair.

[0036] The lower part of the fixed base 21 is fixedly installed on the upper surface of the connecting body 231. The first limiting block 232 restricts the lateral movement distance of the threaded mounting plate 221, and the second limiting block 233 restricts the longitudinal movement distance of the threaded mounting plate 221, so as to prevent the threaded mounting plate 221 from shifting in the rectangle formed by the first limiting block 232 and the second limiting block 233. By setting the first limiting block 232 and the second limiting block 233, the effect of quick positioning during installation is achieved.

[0037] The fixing component 26 includes a bolt 261 and a washer 262. After the washer 262 is fitted onto the bolt 261, it passes through the positioning hole 245 and the connecting hole 234 and is fixed to the threaded groove 222.

[0038] Bolt 261 is used to fix the position of positioning hole 245, connecting hole 234 and threaded groove 222. The setting of gasket 262 can protect bolt 261 from contact with the lower surface of flip body 241 and avoid wear.

[0039] A rotating fixing plate 242 is symmetrically arranged below the rotating body 241. Both rotating fixing plates 242 are provided with rotating grooves 243. A fastener 244 is installed on the outer wall of one of the rotating fixing plates 242. A pin assembly 25 is rotatably arranged on the rotating fixing plate 242.

[0040] The flipping body 241 is attached to the second limiting block 233, and the flipping fixing plate 242 is fixed to the flipping body 241, providing a setting position for the rotating groove 243. The rotating groove 243 set on the two flipping fixing plates 242 provides an installation position for the pin assembly 25.

[0041] The pin assembly 25 includes a rotating shaft 251, which is rotatably disposed in two rotating slots 243. A shaped part 252 is installed on the part of the rotating shaft 251 outside the flip fixing plate 242, and the shaped part 252 is fixed in the fastener 244.

[0042] The rotating shaft 251 is fixedly installed with the irregular part 252, and the irregular part 252 is fixedly fixed with the fastener 244, thereby restricting the rotation of the rotating shaft 251 and preventing the rotating shaft 251 from sliding out of the rotating groove 243.

[0043] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
