Description

Technical Field

[0001] The present application relates to the technical field of mining vehicles, for example, to a mining vehicle compartment bucket guide device and a mining vehicle. Background Art

[0002] At present, mining vehicles are off-road vehicles in mining and engineering environments. As important transportation equipment for open-pit mining, mining vehicles are widely used. Mining vehicles use their compartments to load materials. During the transportation of materials, the compartments will be subjected to lateral loads due to the centrifugal force of the steering. At the same time, the compartment needs to be accurately lowered to the specified position after unloading. This requires the installation of guide and limit devices on the compartment and frame to ensure the fixation of the compartment during material transportation and the accurate lowering of the compartment after unloading.

[0003] There is a mining vehicle in the related technology, which is equipped with guide and limit devices on the left and right longitudinal beams of the car body floor and the left and right longitudinal beams of the frame respectively. Taking into account the factors of manufacturing errors, the guide and limit devices are usually welded on the frame and the car body after the above parts are installed. The limit device is used to limit the lateral movement of the car body to overcome the lateral load of the car body, and the guide device is used to guide the descending car body.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Fuel tanks, hydraulic oil tanks, cables, wiring harnesses, hydraulic pipelines, etc. are usually arranged on both sides of the left and right longitudinal beams of the frame. The guide and limit devices will affect the layout and installation of the above components. The welding slag and high temperature when welding the guide and limit devices may damage the above components. In addition, installing the guide and limit devices at the same time will increase the cost of the mining vehicle.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0031] Unless otherwise stated, the term "plurality" means two or more.

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0033] Combination Figure 1-4 As shown, an embodiment of the present disclosure provides a mining carriage bucket guide device, comprising: a limit support 100 and a guide support 200 . A limiting groove 110 is arranged on the inner side of the limiting support 100; the guide support 200 is arranged above or below the limiting support 100, and a guide protrusion 210 is arranged on the side wall of the guide support 200 facing the limiting groove 110. When the guide support 200 moves toward the limiting support 100, the guide protrusion 210 extends into the limiting groove 110 and detachably abuts against the inner wall thereof. When the guide support 200 moves away from the limiting support 100, the guide protrusion 210 escapes from the limiting groove 110. In particular, when the mining car bucket guide device is assembled on a mining car for use, one of the limiting support 100 and the guide support 200 is installed on the bucket 400, and the other is installed on the vehicle frame 300. The cooperation of the limiting groove 110 and the guide protrusion 210 is used to provide lateral limitation and guidance for the bucket during falling. The cooperation between the limiting groove 110 and the guiding protrusion 210 provides lateral limiting and guidance for the box when falling, so that the box can be accurately dropped to the specified position.

[0034] The limit support 100 is fixed on the vehicle frame 300, and the guide support 200 is fixed on the box 400. A gap adjustment piece can be welded between the guide support 200 and the box 400. The gap adjustment piece is welded on the guide support 200 as needed to compensate for manufacturing errors.

[0035] Optionally, the limiting support 100 and the guide support 200 are made of cast iron material. In this way, the limiting support 100 made of cast iron material has higher strength and compression resistance, can withstand larger impact loads, and also has better wear resistance.

[0036] Optionally, lubricating oil is applied to the inner wall of the limiting groove 110, and lubricating oil is applied to the outer wall of the guide protrusion 210. When the guide support 200 and the inner wall of the limiting groove 110 abut against each other, the friction force on the guide support 200 and the limiting groove 110 is small, and the noise generated by friction can also be reduced.

[0037] Optionally, when the guide protrusion 210 extends into the limiting groove 110 and abuts against it, there is a gap between the limiting support 100 and the guide support 200. In this way, when the box 400 falls on the frame 300, the guide protrusion 210 extends into the limiting groove and abuts against it, and there is a gap between the limiting support 100 and the guide support 200 to prevent the limiting support 100 from colliding with the guide support 200.

[0038] Optionally, when the limiting support 100 is located below the guide support 200, the length of the limiting support 100 in the horizontal direction is greater than the length of the guide support 200 in the horizontal direction. In this way, the length of the limiting support 100 is relatively long, so that the length of the limiting groove 110 is relatively long, the area of ​​the limiting groove 110 is relatively large, and the guide protrusion 210 is more likely to fall into the limiting groove 110 during the falling process.

[0039] It can be understood that the length of the limiting support 100 in the horizontal direction is greater than the length of the guiding support 200 in the horizontal direction, which means that in the horizontal direction, the length of the limiting support 100 protruding from the side wall to which it is connected and the length of the guiding support 200 protruding from the side wall to which it is connected.

[0040] Optionally, the limiting groove 110 and the guide protrusion 210 are trapezoidal or triangular, and the length of the limiting groove 110 in the horizontal direction gradually shortens in the direction facing away from the guide support 200. In this way, the vertical side wall of the limiting groove 110 and the lateral side wall at the bottom of the limiting groove 110 are inclined, so that the opening of the limiting groove 110 at one end facing the guide support 200 is larger, and the guide protrusion 210 is easier to extend into the limiting groove 110, and under the guidance of the vertical side wall of the limiting groove 110, the box bucket 400 is provided with lateral limitation and guidance when falling, so that the box bucket 400 accurately drops to the specified position.

[0041] Optionally, the maximum length of the limiting groove 110 in the horizontal direction is greater than or equal to one third of the length of the limiting support 100 in the horizontal direction, and less than or equal to three quarters of the length of the limiting support 100 in the horizontal direction. In this way, when the maximum length of the limiting groove 110 in the horizontal direction is less than one third of the length of the limiting support 100 in the horizontal direction, the maximum length of the limiting groove 110 in the horizontal direction is relatively small, and the difficulty of the guide protrusion 210 extending into the limiting groove 110 increases. When the maximum length of the limiting groove 110 in the horizontal direction is greater than three quarters of the length of the limiting support 100 in the horizontal direction, the maximum length of the limiting groove 110 in the horizontal direction is too large, so that the structural strength of the limiting support 100 is low, and the risk of breaking of the limiting support 100 is increased. It can be seen that the maximum length of the limiting groove 110 in the horizontal direction is greater than or equal to one third of the length of the limiting support 100 in the horizontal direction, and is less than or equal to three quarters of the length of the limiting support 100 in the horizontal direction. It is more reasonable, the guide protrusion 210 is easier to extend into the limiting groove 110, and the structural strength of the limiting support 100 is relatively high.

[0042] Specifically, the maximum length of the limiting groove 110 in the horizontal direction is equal to two-thirds of the length of the limiting support 100 in the horizontal direction. In this way, the guide protrusion 210 is easier to extend into the limiting groove 110, and the structural strength of the limiting support 100 is relatively high.

[0043] Optionally, the length of the guide protrusion 210 in the horizontal direction gradually shortens in the direction toward the limiting groove 110. In this way, the length of the guide protrusion 210 in the horizontal direction at one end toward the limiting groove 110 is relatively short, and the guide protrusion 210 is easier to extend into the limiting groove 110, and the cooperation between the limiting groove 110 and the guide protrusion 210 provides the compartment 400 with lateral limitation and guidance when falling, so that the compartment 400 can accurately drop to the specified position.

[0044] Optionally, the maximum length of the guide protrusion 210 in the horizontal direction is smaller than the length of the guide support 200 in the horizontal direction. In this way, the length of the guide support 200 in the horizontal direction is longer than the maximum length of the guide protrusion 210 in the horizontal direction, the length of the guide support 200 in the horizontal direction is relatively long, and when the guide support 200 is connected to the frame 300, the connection stability is higher.

[0045] Specifically, the maximum length of the guide protrusion 210 in the horizontal direction is equal to two-thirds of the length of the guide support 200 in the horizontal direction.

[0046] Optionally, the length of the guide protrusion 210 in the vertical direction is less than or equal to the length of the limiting groove 110 in the vertical direction, and greater than or equal to one half of the length of the limiting groove 110 in the vertical direction. In this way, when the length of the guide protrusion 210 in the vertical direction is greater than the length of the limiting groove 110 in the vertical direction, the risk of the box 400 falling to the lateral side wall of the guide protrusion 210 and colliding with the limiting groove 110 is relatively high, and the vertical side wall of the guide protrusion 210 will form a gap with the vertical side wall of the limiting groove 110, so that the risk of the guide protrusion 210 shaking in the limiting groove 110 is relatively high, reducing the accuracy of the guidance. In the case where the length of the guide protrusion 210 in the vertical direction is less than half of the length of the limiting groove 110 in the vertical direction, during the process of the box 400 falling onto the frame 300, due to the short length of the guide protrusion 210 in the vertical direction, the box 400 needs to fall a long distance before the guide protrusion 210 can extend into the limiting groove 110, which makes it difficult to achieve effective guiding and limiting effects. Therefore, it is more reasonable that the length of the guide protrusion 210 in the vertical direction is less than or equal to the length of the limiting groove 110 in the vertical direction, and greater than or equal to half of the length of the limiting groove 110 in the vertical direction. The vertical side wall of the guide protrusion 210 abuts against the vertical side wall of the limiting groove 110, reducing the risk of the guide protrusion 210 shaking in the limiting groove 110. The length of the guide protrusion 210 in the vertical direction is relatively long, and the guide protrusion 210 cooperates with the limiting groove 110 to provide better guiding and limiting effects.

[0047] Specifically, the length of the guide protrusion 210 along the vertical direction is equal to the length of the limiting groove 110 along the vertical direction.

[0048] Specifically, the length of the guide protrusion 210 along the vertical direction is equal to two thirds of the length of the limiting groove 110 along the vertical direction.

[0049] The mining vehicle provided by the embodiment of the present disclosure includes the mining vehicle compartment bucket guide device of the above embodiment. When the mining vehicle compartment bucket guide device is assembled on the mining vehicle for use, one of the limit support 100 and the guide support 200 is installed on the compartment bucket 400, and the other is installed on the vehicle frame 300. The parts required for disassembly and assembly are relatively few, which simplifies the disassembly and assembly process and reduces the cost. The limit groove 110 and the guide protrusion 210 provide guidance for the compartment bucket 400, so that the compartment bucket 400 can be accurately lowered to the specified position.
