Description

Technical Field

[0001] This utility model belongs to the technical field of mining dump trucks, specifically relating to a cargo box tipping mechanism and a mining dump truck. Background Technology

[0002] Mining dump trucks are commonly used for transporting and moving minerals within mines. This results in mining dump trucks having shorter travel distances and higher frequency of cargo box raising and lowering compared to other types of dump trucks. However, during the repeated raising and lowering of the cargo box, the tilting structure responsible for the tilting function is prone to wear and deformation, requiring frequent maintenance and replacement. In existing tilting structures, the tilting shaft is welded to a fixed bushing. Once wear occurs at the position of the tilting shaft corresponding to the tilting seat assembly, the tilting shaft is difficult to disassemble and replace. Furthermore, the existing tilting seat assembly is bolted to the cargo box, and after prolonged use, the connecting bolts may loosen or fall off, all of which affect daily use and maintenance. Utility Model Content

[0003] This utility model provides a cargo box tipping mechanism and a mining dump truck, which solves the technical problems of existing mining dump truck tipping structures having defects such as the tipping shaft being difficult to disassemble and the tipping seat assembly not being firmly connected to the cargo box, thus affecting the normal use and maintenance of the mining dump truck.

[0004] This utility model discloses a cargo box tipping mechanism, comprising:

[0005] Fixed bushing;

[0006] A flip shaft, one end of which is inserted into the fixed bushing, and the fixed bushing is connected to the flip shaft radially by at least one set of detachable, anti-loosening fastener assemblies;

[0007] The flip-base assembly includes a sleeve sleeved at the other end of the flip shaft, and the flip-base assembly also includes a base plate reinforcing plate.

[0008] Furthermore: The outer end of the sleeve is provided with an end cap. The beneficial effect of this step is that, in order to make the rotation smoother, grease is filled in the gap between the rotating shaft and the sleeve. However, the operating environment of the mining dump truck is dusty, and the grease itself is also very sticky, which will inevitably attract dust. Under long-term use, more and more dust will mix into the gap, affecting the smoothness of rotation. Therefore, it is necessary to set an end cap on the outside of the sleeve for dust protection.

[0009] Furthermore: when there is at least one set of the removable, anti-loosening fastener assembly, each set of the fastener assembly includes a bolt with a hole in the rod, a slotted nut, and a cotter pin. The beneficial effect of this step is that the cotter pin and the slotted nut cooperate to restrict the rotation of the slotted nut, thereby playing an anti-loosening role.

[0010] Furthermore: when there are at least two sets of the detachable, anti-loosening fastener assembly, each set of the fastener assembly includes a bolt and a nut with a hole in the head, and a perforated steel wire is wound between multiple bolts with holes in the head. The beneficial effect of this step is that the perforated steel wire ensures that multiple bolts do not rotate, thus playing an anti-loosening role.

[0011] Furthermore, the sleeve is also provided with an oil injection hole, and the oil injection hole is provided with a pressure oil injection cup. The beneficial effect of this step is that lubricating grease is injected into the gap between the sleeve and the rotating shaft through the pressure oil injection cup.

[0012] Furthermore, the bottom plate reinforcing plate is provided with plug welding holes. The beneficial effect of this step is that by plugging welding holes, the weld length between the bottom plate reinforcing plate and the cargo box assembly is increased, thereby improving the welding strength.

[0013] Furthermore: the position of the flipping shaft corresponding to the sleeve is a stepped shaft, and the sleeve abuts against the stepped shaft. The beneficial effect of this step is that the sleeve is positioned using the stepped shaft.

[0014] Furthermore: a positioning groove is provided inside the sleeve at the position corresponding to the outer end face of the flipping shaft, and a retaining ring for the hole is provided in the positioning groove. The beneficial effect of this step is that the sleeve is positioned at both ends by combining the stepped shaft and the retaining ring for the hole.

[0015] This utility model also provides a mining dump truck, including:

[0016] Chassis assembly;

[0017] The cargo box tipping mechanism described in either of the two foregoing contents is mirror-mounted on the vehicle frame assembly, and the fixed bushing is welded to the vehicle frame assembly;

[0018] The cargo box assembly is welded to the bottom plate reinforcing plate of the cargo box tipping mechanism.

[0019] The tilting structure of the mining dump truck provided by this utility model is easier to install and maintain, and has better durability.

[0020] The beneficial effects of this utility model are:

[0021] 1. In the cargo box tilting structure of this application, the tilting shaft is easier to disassemble, and the bottom plate reinforcement plate is more firmly connected to the cargo box, which can improve the efficiency of installation and maintenance, as well as the reliability of daily use;

[0022] 2. The reliability of the mining dump truck in this application is further improved in the case of frequent tipping. Attached Figure Description

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0031] Example

[0032] This utility model addresses the technical problems of existing mining dump truck tipping structures, such as inconvenient installation and maintenance, and the tendency for the bottom plate reinforcement plate to loosen easily during prolonged use due to bolted connections with the cargo box assembly. A new technical solution is proposed, specifically as follows: Figure 1 As shown, this utility model provides a cargo box tipping mechanism, comprising:

[0033] Fixed bushing 1 is generally welded to the frame assembly by channel steel or other profiles;

[0034] A flip shaft 2 is provided, one end of which is inserted into the fixed bushing 1. The fixed bushing 1 and the flip shaft 2 are connected radially by at least one set of detachable and anti-loosening fastener assemblies 4. The fastener assemblies 4 prevent the flip shaft 2 from rotating. The fastener assemblies 4 are detachable and anti-loosening. The assembly process does not require welding, making it faster and more convenient.

[0035] The flip seat assembly 3 includes a sleeve 31, which is sleeved on the other end of the flip shaft 2. The flip seat assembly 3 also includes a bottom plate reinforcing plate 32, which strengthens the welding strength with the cargo box assembly.

[0036] In one embodiment, the outer end of the sleeve 31 is provided with an end cap. In order to make the rotation smoother, grease is filled in the gap between the rotating shaft 2 and the sleeve 31. However, the operating environment of the mining dump truck is dusty, and the grease itself is also very sticky, which will inevitably attract dust. Under long-term use, more and more dust will mix into the gap, affecting the smoothness of rotation. Therefore, an end cap needs to be provided on the outside of the sleeve 31 for dust protection.

[0037] In one embodiment, when there is at least one set of the detachable, anti-loosening fastener assembly 4, each set of the fastener assembly 4 includes a bolt with a hole in the rod, a slotted nut, and a cotter pin. The cotter pin and the slotted nut cooperate to restrict the rotation of the slotted nut, thereby playing an anti-loosening role.

[0038] In one embodiment, when there are at least two sets of the detachable, anti-loosening fastener assembly 4, each set of the fastener assembly 4 includes a bolt and a nut with a hole in the head, and a perforated steel wire is wound between multiple bolts with holes in the head. The steel wire is generally wound in a figure-eight shape through the holes. The steel wire wound through the holes ensures that multiple bolts do not rotate, thereby playing an anti-loosening role.

[0039] In one embodiment, the sleeve 31 is also provided with an oil injection hole, and the oil injection hole is provided with a pressure oil injection cup 311. The pressure oil injection cup 311 is generally located in the middle section of the sleeve 31. Lubricating grease is injected into the gap between the sleeve 31 and the flip shaft 2 through the pressure oil injection cup 311, and then diffused to both ends of the sleeve 31, which can better ensure that the lubricating grease is fully filled in the gap.

[0040] In one embodiment, the bottom plate reinforcing plate 32 is provided with plug welding holes, which increase the number of welds and the total length of welds between the bottom plate reinforcing plate and the cargo box assembly, thereby improving the welding strength.

[0041] In one embodiment, the position of the flipping shaft 2 corresponding to the sleeve 31 is a stepped shaft, and the sleeve 31 abuts against the stepped shaft, thereby positioning the sleeve 31.

[0042] Based on the above technical solution, a positioning groove is provided in the sleeve 31 at the position corresponding to the outer end face of the flip shaft 2. A retaining ring for the hole is provided in the positioning groove. The sleeve 31 is positioned at both ends in combination with the stepped shaft and the retaining ring for the hole, so as to ensure that the sleeve 31 does not move axially on the flip shaft 2.

[0043] This utility model also provides a mining dump truck, including:

[0044] Chassis assembly;

[0045] The cargo box tipping mechanism described in either of the two foregoing contents is mirror-mounted on the vehicle frame assembly, and the fixed bushing is welded to the vehicle frame assembly;

[0046] The cargo box assembly is welded to the bottom plate reinforcing plate of the cargo box tipping mechanism.

[0047] Assuming the cargo box assembly is installed on a cargo box tipping mechanism in the same direction, if the cargo box assembly moves laterally, it may detach from the cargo box tipping mechanism. Therefore, the cargo box tipping mechanism needs to be mirrored.

[0048] The tilting structure of the mining dump truck provided by this utility model is easier to install and maintain, and has better durability.
