Description

Technical Field

[0001] This utility model relates to the technical field of bucket wheel excavators, and in particular to a bucket wheel excavator frame equipped with a driver's cab. Background Technology

[0002] Some bucket wheel excavators are large and do not have a cab. The operator usually stands on one side of the vehicle and remotely controls the entire vehicle using a controller. However, the operator's field of vision is limited by the vehicle, and they cannot see the situation in the other three directions around the vehicle, which can easily lead to accidents. In addition, some existing vehicles have a frame, namely a portal frame, with two centers of gravity. Both centers of gravity are off the rotating base at the bottom of the vehicle, which is not conducive to the stability of the overall mechanism. The operator needs to be extremely careful to avoid the vehicle from swaying from side to side. Utility Model Content

[0003] To increase the operator's field of vision and enhance the stability of the overall vehicle structure, this utility model provides a bucket wheel excavator frame equipped with a cab.

[0004] The present invention provides a bucket wheel excavator chassis with a driver's cab, which adopts the following technical solution:

[0005] A bucket wheel excavator frame equipped with a cab includes a vehicle chassis and a frame. A rotating base is installed on the top of the vehicle chassis. The inner ring turntable of the rotating base is fixedly connected to the bottom of the frame. A telescopic conveyor base is installed on the top of the middle of the frame. A conveyor ladder is fixedly connected to the inner ring turntable of the telescopic conveyor base. The main body and the cab are fixedly connected to the top of one end of the frame.

[0006] Preferably, the cab is equipped with a controller with a display, and the frame is equipped with an image device that is communicatively connected to the controller.

[0007] By adopting the above technical solution, a driver's cab is provided on the vehicle chassis, allowing the driver to see any situation in a 360° horizontal direction, avoiding blind spots and thus preventing vehicle damage caused by safety accidents or other collisions. This also helps to increase the operator's field of vision and enhance the stability of the overall vehicle structure.

[0008] Preferably, a maintenance door is provided on one side of the main body leading to the interior of the main body, and a connecting door is provided between the interior of the main body and the driver's cab.

[0009] By adopting the above technical solution, when the cab cannot be opened from the outside, the interior of the main body can be entered through the maintenance door, and then the cab can be opened.

[0010] Preferably, the turntable center axes of the rotating base and the telescopic conveyor base overlap.

[0011] Preferably, the center of gravity of the vehicle as a whole overlaps with the center of gravity of the rotating base.

[0012] By adopting the above technical solution, the rotating base and the telescopic conveyor on the chassis are on the same axis, and the vehicle has only one center of gravity. When the rotating base and the telescopic conveyor base rotate at the same time, the vehicle body will not sway from side to side, thus enhancing the stability of the vehicle.

[0013] Preferably, the width of the cab is smaller than the width of the vehicle frame.

[0014] By adopting the above technical solutions, the body width of large bucket wheel excavators is usually between 4 and 10 meters, and the width of the single-person cab is generally between 1.8 and 2.5 meters. It is set on the left and right sides of the frame, which reduces the load and avoids affecting the center of gravity of the vehicle.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] As the technical solution of this utility model, the provided hardware configuration is merely to facilitate increasing the operator's field of vision and enhancing the stability of the overall vehicle structure based on the hardware facilities. The specific methods for achieving this increased field of vision and enhanced stability are not considered the technical problem to be solved or the object of protection of this utility model. Furthermore, the communication methods between the devices all employ existing communication methods and are not the innovation of this application.

[0017] 1. The vehicle chassis of this device is equipped with a driver's cab, and a detection image device is installed on the frame. The driver can see any situation in the horizontal 360° direction from inside the driver's cab 3, avoiding blind spots and thus avoiding vehicle damage caused by safety accidents or other collisions. It helps to increase the operator's field of vision and enhance the stability of the overall vehicle structure.

[0018] 2. The rotating base and the telescopic conveyor base of this device are located on the same axis, and the vehicle has only one center of gravity. When the rotating base and the telescopic conveyor base rotate at the same time, the vehicle body will not sway from side to side, thus enhancing the stability of the vehicle.

[0019] 3. This device modifies the size of the chassis, increasing its utilization rate. On a vehicle chassis of the same size, while the chassis and cab are on the body, the overall vehicle still bears the force in the middle without affecting the overall working performance. At the same time, the main body has a maintenance door, and there is still a door between the cab and the main body. From the perspective of the maintenance door, when the door on the side of the cab away from the center of the vehicle is locked due to an external malfunction, the cab can still be entered through the maintenance door of the main body and opened from the inside in an emergency.

[0026] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0027] Reference Figure 5 There is a rotating base 4 between the lower part of the portal frame and the vehicle chassis 1. Using the existing installation method, the rotating base 4 and the telescopic conveyor base 5 are fixed to the frame of the bucket wheel excavator. The main body 7 is installed at one end of the portal frame, and a rotatable telescopic conveyor base 5 is installed on the top behind it. The installation part 9 of the telescopic conveyor base is located in the middle of the portal frame. A conveyor ladder 6 is also installed on the telescopic conveyor base 5. Therefore, the vehicle itself has two centers of gravity, both of which are detached from the rotating base 4 at the bottom of the vehicle. Therefore, the overall stability and mechanical performance requirements of the vehicle are relatively high.

[0028] This utility model discloses a bucket wheel excavator chassis equipped with a driver's cab.

[0029] Reference Figure 1 , Figure 4The vehicle includes a vehicle chassis 1 and a frame 2. A rotating base 4 is mounted on the top of the vehicle chassis 1. The inner ring turntable of the rotating base 4 is fixedly connected to the bottom of the frame 2. A telescopic conveyor base 5 is mounted on the top of the middle of the frame 2. A conveyor ladder 6 is fixedly connected to the inner ring turntable of the telescopic conveyor base 5. The main body 7 and the cab 3 are fixedly connected to the top of one end of the frame 2. On a vehicle chassis of the same size as in the background art, the frame 2 and the cab 3 are present on the vehicle body, which still allows the middle of the vehicle to bear the force and does not affect the overall working performance of the vehicle.

[0030] Reference Figure 2 , Figure 3 , Figure 4 The cab 3 is equipped with a controller with a display, and the outer surface of the frame 2 is equipped with a detection image device. The detection image device is a 360-degree image device, which can transmit the image data of the vehicle's surroundings to the controller and then display it on the display. The driver can see any situation in the horizontal 360° direction from the cab, avoiding blind spots. The detection image device is connected to the controller.

[0031] Reference Figure 2 A maintenance door 8 is provided on one side of the main body 7 to lead to the interior of the main body 7. A connecting door is provided between the interior of the main body 7 and the cab 3. When the door on the side of the cab 3 away from the center of the vehicle is locked due to an external malfunction, the cab 3 can still be entered through the maintenance door 8 of the main body 7 and the cab 3 can be opened from the inside in an emergency.

[0032] Reference Figure 4 The turntable center axes of the rotating base 4 and the telescopic conveyor base 5 overlap, and the overall center of gravity of the vehicle overlaps with the center of gravity of the rotating base 4. The vehicle itself has two centers of gravity, one on the rotating base 4 and the other on the telescopic conveyor base 5. The vertical center axes of the two rotating bases 4 and the telescopic conveyor base 5 overlap, meaning that neither center of gravity has left the rotating base 4 at the bottom of the vehicle. Even if the conveyor ladder 6 and the frame 2 rotate in different directions, there is no need to worry about the vehicle body being unstable.

[0033] Reference Figure 2 , Figure 3 The width of the cab 3 is smaller than the width of the frame 2, ensuring that the center of gravity of the frame 2 is still located in the middle of the vehicle and on the rotating base 4, so as to avoid the vehicle body becoming unstable due to the cab being too light.

[0034] The implementation principle of a bucket wheel excavator frame equipped with a cab according to an embodiment of this utility model is as follows:

[0035] 1. A driver's cab 3 is provided on the vehicle chassis 1, and a detection image device is installed on the frame 2. The driver can see any situation in the horizontal 360° direction from inside the driver's cab 3, avoiding blind spots and thus avoiding vehicle damage caused by safety accidents or other collisions. This helps to increase the operator's field of vision and enhance the stability of the overall vehicle structure.

[0036] 2. The rotating base 4 and the telescopic conveyor base 5 are located on the same axis, and the vehicle has only one center of gravity. When the rotating base 4 and the telescopic conveyor base 5 rotate at the same time, the vehicle body will not sway from side to side, thus enhancing the stability of the vehicle.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
