[0025] It should also be noted that the directional terms such as left, right, up and down in the embodiments of the present application are merely relative concepts or are based on the normal use status of the product, and should not be considered as restrictive.
[0026] Please refer to Figures 1 to 4 Now, a dump truck cab roof structure and a mining dump truck provided by the utility model are exemplarily described. This embodiment discloses a dump truck cab roof structure including a cab frame 100, a cover plate 10 and a collecting trough 12. The cover plate 10 is arranged on the top of the cab frame 100, and the edge of the cover plate 10 extends beyond the top edge of the cab frame 100 to block rainwater and prevent rainwater from directly dripping on the glass of the cab after gathering and affecting the driver's field of vision.
[0027] The cab frame 100 includes a top frame, a bottom frame, a plurality of columns and two front baffles; the top frame is suspended on the bottom frame through a plurality of columns, and a skin layer is arranged between adjacent columns. The two front baffles are arranged on the two columns on the front side of the cab frame and are curved. The two front baffles are arranged at intervals in the up-down direction, and the front windshield is arranged between the two front baffles and is adaptively arranged into a curved surface structure, so that the driver's front field of vision can be increased.
[0028] The collecting trough 12 extends along the edge of the cover plate 10 from the front side of the cover plate 10 to the rear side of the cover plate 10 to collect water flowing from the top surface of the cover plate 10; the collecting trough 12 is provided with a drain port 13 for draining the water collected in the collecting trough 12. In the application scenario of rain, rain falls on the roof of the dump truck cab, flows along the top surface of the cab roof into the collecting trough 12, and then is discharged from the drain port 13, so that the water flow can be discharged at a fixed point, solving the problem of arbitrary dripping of the roof water flow, and providing convenience for people to enter and exit the cab in rainy weather.
[0029] The collecting trough 12 of this embodiment includes a front collecting portion 121 extending along the front edge of the cover plate 10 and a guide portion 122 extending from the front side of the cover plate 10 toward the rear side of the cover plate 10, and one end of the guide portion 122 toward the front collecting portion 121 is connected to the front collecting portion 121. The front collecting portion 121 is used to collect the water flow that converges from the front edge of the top of the cover plate 10, so as to prevent the water flow mixed with dust from falling on the front windshield of the cab or falling near the front windshield, so as to prevent the front windshield from being polluted and affecting the driving vision. The guide portion 122 can collect the water flow from the top surface of the cover plate 10 near the side of the door, so as to prevent the water flow from falling from the top surface of the cover plate 10 near the side of the door, hindering the driver from entering and exiting the cab. The rear collecting portion 123 is used to collect the water flow that converges from the rear edge of the top surface of the cover plate 10, so as to prevent rainwater from dripping disorderly from the rear edge of the top surface of the cover plate 10.
[0030] In another embodiment of the present application, the guide portion 122 is arranged to extend downwardly from the front side of the cover plate 10 to the rear side of the cover plate 10 at an angle, and the guide portion 122 can guide the water flow of the front collecting portion 121 to the rear collecting portion 123, thereby reducing the water flow in the front collecting portion 121, and preventing the water flow from being spilled onto the front windshield or near the front windshield due to the shaking of the vehicle when the water level in the front collecting portion 121 is too high. In addition, the water flow of the guide portion 122 can also be reduced, and the water flow can also be prevented from being spilled due to the shaking of the vehicle when the water level in the guide portion 122 is too high. On the other hand, since the guide portion 122 is arranged at an angle, the water flow velocity in the guide portion 122 is relatively high, which can prevent dust from accumulating in the collecting trough to a certain extent.
[0031] In another embodiment of the present application, the collector also includes a rear collector 123 extending along the rear edge of the cover plate 10, the height of the rear collector 123 is lower than the height of the front collector 121, the length direction of the front collector 121 is parallel to the front edge of the cover plate, and the length direction of the rear collector 123 is parallel to the length direction of the front collector 121. The end of the guide 122 away from the front collector 121 is connected to the rear collector 123, and the water collected by the front collector 121 is guided to the rear collector 123 by the guide 122. The drain port 13 is opened in the rear collector 123. In actual application scenarios, the water flows through the guide to the rear collector 123 under the action of its own gravity, and is finally discharged from the drain port 13, so that the water can be discharged from the fixed point on the rear side of the cab to avoid affecting the driver's entry and exit of the cab, and the impact of the discharged water flow is minimized. Of course, in other embodiments, the location of the drain port 13 can also be changed according to actual needs, as long as it can ensure that the water flow from the collecting trough 12 can be discharged without interfering with the driver's entry into the cab and affecting the driver's vision.
[0032] In another embodiment of the present application (not shown in the figure), the rear collecting part 123 may not be provided, and the drain port 13 is provided at one end of the guide part 122 away from the front collecting part 121, and the position of the drain port 13 is staggered with the position of the door in the front-to-back direction, so that the water discharge position can be staggered with the position of the door, avoiding the drainage process from affecting the driver's entry and exit of the cab. Preferably, the end of the guide part 122 away from the front collecting part 121 is open, and the open port constitutes the drain port 13. Since the setting of the drain port is located in the drainage direction of the guide part 122, on the one hand, the water flow of the guide part 122 is directly discharged from the drain port without turning during the process, which can reduce the probability of dust accumulation in the water flow at the turning point, and on the other hand, the inclined guide part 122 allows the water flow to obtain a higher flow velocity under the action of its own gravity, and the water flow directly flushes the drain port, which further prevents the dust in the water flow from accumulating at the drain port and causing the drain port to be blocked.
[0033] In another embodiment of the present application, two guide parts are configured, and the two guide parts are located on opposite sides of the cover plate 10; the positive projection of the collecting groove 12 on the plane where the cover plate 10 is located surrounds the cover plate 10. In this way, the water flow collected by the cover plate 10 can be collected in all directions.
[0034] In this embodiment, the drain port 13 is provided on the side of the rear header 123 facing away from the front header 121. Of course, in other embodiments (not shown in the figure), the drain port 13 is also provided on the bottom wall of the rear header 123. Specifically, the drain port 13 penetrates the rear header 123 downward from the bottom surface inside the rear header 123. In addition, the drain port 13 can also be provided at other positions of the rear header 123 as long as it can discharge water.
[0035] Furthermore, the number of the drain ports 13 can be two or more. For example, in this embodiment, there are two drain ports 13, and the two drain ports 13 are arranged on the rear manifold 123, which can increase the drainage speed. Of course, in other embodiments, the number of the drain ports 13 and the location of the drain ports 13 can also be changed according to actual needs.
[0036] Please combine Figure 2 In this embodiment, a threaded hole 14 is provided on the top surface of the cover plate 10, and the threaded hole 14 is used for the installation of the lifting ring 11, so as to facilitate the lifting of the cover plate 10 through the lifting ring 11 to complete the assembly of the cab. Among them, the cover plate 10 includes a reinforcing steel plate 101 and a top cover skin 102 covering the top surface of the reinforcing steel plate 101. The collecting trough 12 is formed at the edge of the top cover skin 102. Specifically, the top cover skin 102 includes a skirt plate 1021 extending downward from the edge of the reinforcing steel plate 101 and a curled portion 1022 curled from the lower edge of the skirt plate 1021 in a direction away from the reinforcing steel plate 101, and the collecting trough 12 is defined by the curled portion 1022 and the skirt plate 1021. The reinforcing steel plate can improve the structural strength of the cover plate 10, so that the cover plate 10 can withstand greater impact force and provide better protection for the personnel in the cab.
[0037] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
