Description

Technical Field

[0001] This invention relates to the field of mining dump truck technology, and in particular to an anti-collision driver's cab frame and a mining dump truck. Background Technology

[0002] Due to the complex road conditions and harsh working environment, rollover accidents involving mining dump trucks are difficult to avoid, and such accidents can easily cause fatal injuries to the driver. To ensure driver safety, the internationally accepted method is to install rollover protection structures on mining dump trucks. However, practical experience has shown that rollover protection structures that merely meet international standards are insufficient to guarantee driver safety during a rollover. A rollover of a mining dump truck is a dynamic impact process; once a rollover accident occurs, excessive deformation of the driver's cab can crush the driver, making rescue difficult and potentially resulting in serious injury or death. Summary of the Invention

[0003] A primary objective of this invention is to overcome at least one of the deficiencies of the prior art and to provide a collision-resistant driver's cab frame that can assist the driver in reserving escape time and has a small degree of deformation in the event of a rollover.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] According to one aspect of the present invention, a collision-resistant driver's cab frame is provided for a driver's cab of a mining dump truck, wherein the collision-resistant driver's cab frame includes a base frame, a top frame, multiple uprights, and a displacement sensor; the base frame is formed by multiple bottom beams, adjacent bottom beams being connected via corner posts; the top frame is located above the base frame and is formed by multiple top beams, adjacent top beams being connected via corner posts; the multiple uprights are respectively connected between multiple corner posts of the base frame and multiple corner posts of the top frame; the displacement sensor... The displacement sensor, located on the outer side of the top beam, is used to measure the ground clearance of the top beam when the mining dump truck overturns, providing the driver with information to determine the best time to escape.

The two top longitudinal beams are arranged at intervals along a second direction perpendicular to the first direction. The outer surfaces of the two top longitudinal beams are respectively provided with multiple displacement sensors, and the multiple displacement sensors located on the same top longitudinal beam are arranged at intervals along the first direction.

[0007] According to one embodiment of the present invention, a buffer filler layer is filled between two adjacent layers of the grid structure of the anti-collision beam structure.

[0008] According to one embodiment of the present invention, the base frame and the top frame are respectively rectangular, the length of the base frame along a first direction is greater than the length of the top frame along the first direction, the first direction being the length direction of the mining dump truck body; wherein, the columns are arranged at an angle so that the orthographic projection of the anti-collision driver's cab frame on the vertical reference plane is a trapezoidal frame structure, the vertical reference plane being parallel to the first direction.

[0009] According to one embodiment of the present invention, the multiple bottom beams include two bottom longitudinal beams and two bottom transverse beams. The bottom longitudinal beams extend along a first direction, which is the length direction of the mining dump truck body. The bottom transverse beams extend along a second direction perpendicular to the first direction. The underframe also includes a bottom reinforcing transverse beam, which extends along the second direction and connects the two bottom longitudinal beams.

[0011] According to one embodiment of the present invention, the multiple top beams include two top longitudinal beams and two top transverse beams. The top longitudinal beams extend along a first direction, which is the length direction of the mining dump truck body. The top transverse beams extend along a second direction perpendicular to the first direction. The top frame also includes a top reinforcing transverse beam, which extends along the second direction and connects between the two top longitudinal beams. The top reinforcing transverse beam is the aforementioned anti-collision beam structure.

[0012] According to one embodiment of the present invention, the plurality of columns include two first columns and two second columns, the first columns and the second columns being arranged at intervals along a first direction, the first direction being the length direction of the mining dump truck body; the two first columns being arranged at intervals along a second direction perpendicular to the first direction; and the two second columns being arranged at intervals along the second direction; wherein, the anti-collision driver's cab frame further includes a central reinforcing crossbeam and / or a diagonal reinforcing beam; the central reinforcing crossbeam extends along the second direction and connects between the two first columns, the central reinforcing crossbeam being the anti-collision beam structure; the diagonal reinforcing beam is arranged obliquely and connects between the connection point of one second column and the base frame and the connection point of another second column and the top frame.

The third column and the fourth column extend vertically, and the fourth column and the fourth column are arranged at intervals along the first direction. The third column is the anti-collision beam structure.

[0014] As can be seen from the above technical solution, the advantages and positive effects of the anti-collision driver's cab frame proposed in this invention are as follows:

[0015] The anti-collision driver's cab frame proposed in this invention features displacement sensors installed on the outer side of the top beam.

Furthermore, the bottom beam, top beam, and columns of the anti-collision driver's cab frame are all anti-collision beam structures, each comprising a multi-layered grid structure nested from the outside in.

(See also...) Figure 2 and Figure 3 , Figure 2 The diagram shows a three-dimensional structural schematic of the anti-collision beam structure of the anti-collision driver's cab frame, which embodies the principle of the present invention.

Figure 2 The diagram shows the structure of part of the grille structure 510 and the connecting stiffener 520 of the anti-collision beam structure.

The top frame 200 is located above the base frame 100 and is formed by multiple top beams, with adjacent top beams connected by corner posts 220. Multiple uprights are respectively connected between the corner posts 120 of the base frame 100 and the corner posts 220 of the top frame 200. The displacement sensor 400 is disposed on the outer surface of the top beam. The displacement sensor 400 is used to measure the ground clearance of the top beam when the mining dump truck overturns, thereby providing the driver with information to determine the best time to escape. Based on this, the bottom beam, top beam, and columns are all anti-collision beam structures.

Based on this, multiple displacement sensors 400 can be respectively provided on the outer surfaces of the two top longitudinal beams 211, and the multiple displacement sensors 400 located on the same top longitudinal beam 211 are arranged at intervals along the first direction X.
