Excavator with monitoring device

Abstract

Provided is an excavator with a monitoring device. A front end shell and a rear end shell of a counter weight are each provided with a through hole, an image pickup device is arranged inside the counter weight and comprises a box structure, a window portion, a pipe fitting and a camera, the box structure is located at the rear end of the pipe fitting, one end of the box structure is open, and the other end of the box structure is closed; the pipe fitting is a hollow steel pipe with two ends open, the front end of the pipe fitting penetrates through the through hole formed in the front end shell of the counter weight and is fixedly connected with the front end shell of the counter weight, and the rear end of the pipe fitting penetrates through the closed end of the box structure and is fixedly connected with the end face of the closed end of the box structure; the window portion is connected to the port portion of the opening end of the box structure and divides the box structure into a front portion and a rear portion, and the camera is installed on the rear portion of the box structure. The excavator with the monitoring device has the advantages that the camera is fixedly connected to the bottom of the counter weight and / or arranged inside a revolving platform and can be protected, obtained images of rear visibility are more real and easy to identify, and the obtained images are processed through an image synthesizer.

Description

technical field [0001] The invention relates to a construction machine, in particular to an excavator with a monitoring device. Background technique [0002] figure 1 The basic structure of the hydraulic excavator 1 is shown. The hydraulic excavator 1 has a lower traveling mechanism 2 , a slewing mechanism 3 , a slewing platform 4 , a counterweight 16 , a cab 10 , a working device 14 , and the like. The slewing mechanism 3 is above the lower traveling mechanism 2, and the slewing platform 4 can turn in any direction on the slewing mechanism 3. On the slewing platform 4, a cab 10, a counterweight 16, a working device 14, etc. are arranged, and the working device 14 includes a boom 11. , stick 12, bucket 13, etc. are located at the front end of the excavator, the operator is in the cab 10, and the counterweight 16 is located at the rear end of the excavator. [0003] Various electronic components are sometimes mounted on the counterweight 16. In particular, due to the pric...

Problems solved by technology

[0004] In the invention patent application with the application publication number CN103635637 A, a rear view display device for a hydraulic excavator is provided, including a camera for obtaining the rear view of the vehicle at the rear of the upper slewing body, and a monitor for displaying images obtained by the camera device, such as figure 1 However, for construction machines such as large excavators, the structure in which the camera 20 is arranged on the upper surface of the counterweight 16 cannot cover the field of view behind the vehicle, and the height of the camera 20 from the ground is relatively high. , it is necessary to make the shooting angle of the camera 20 from the top to the bottom to obtain the ground image behind the vehicle. The obtained image is unreal and difficult to recognize. It does not affect the slewing operation of the slewing platform at all, but with the structure set on the upper part, the image obtained by the camera cannot truly reproduce its height, which directly affects the normal operation

Moreover, when the vehicle is operating under harsh conditions in the field, the camera 20 is exposed above the counterweight 16 and there is a risk of being hit by falling objects and causing damage.

Moreover, part of the cable connecting the camera 20 is also exposed on the surface of the counterweight 16, and there is also the danger that the cable will be damaged due to impact. Simultaneously, cable damage will also cause the circuit to damage electronic components such as the camera or monitor due to a short circuit.
