Problems solved by technology
[0006] One of the objectives of the present invention is to provide an excavator with a counterweight positioning detection device, which can solve the problem of the existing position of the threaded hole in the bottom groove of the counterweight and the mounting hole on the support component during the installation of the counterweight. Invisible, it is difficult for the operator to observe the vertical alignment of the mounting holes on the support part and the threaded holes on the groove on the bottom of the counterweight

Embodiment 2
[0028]In Embodiment 2, an obvious position mark is provided on the end surface of the groove near the threaded hole 53 corresponding to the mounting hole for connecting the positioning detection device 9 . Before installing the counterweight, first install the positioning detection device 9 on the bottom of the mounting hole 32b on the support member 3a, and then use a marker to set an obvious position near the threaded hole 53 on the corresponding counterweight bottom groove. The position mark is convenient for the operator to better identify the positioning position where the mounting hole 32 and the corresponding threaded hole 53 are aligned up and down during the process of installing the counterweight, so as to improve the installation efficiency of the counterweight.

The invention discloses an excavator provided with a counter weight positioning detection device and a counter weight installing method and relates to the technical field of engineering machinery. The excavator comprises a counter weight provided with two parallel grooves formed in the bottom and supporting parts matched with the grooves formed in the bottom of the counter weight, threaded holes are formed in the grooves, installing holes are formed in the supporting parts, and the counter weight is connected and fixed to the supporting part through counter weight bolts. The excavator further comprises a positioning detection device, wherein the positioning detection device is provided with an image pickup portion and an image display portion. A base is arranged at the bottom of the image pickup portion, the image pickup portion extends into the installing holes formed in the bottom of the supporting parts, and the upper end face of the base is connected with the lower end faces of the installing holes formed in the bottoms of the supporting parts. By means of the counter weight installing method, an operator can observe whether the installing holes formed in the supporting parts are vertically flush with the threaded holes formed in the grooves at the bottom of the counter weight without standing under an excavator main platform, the safety and operating convenience of the operator are improved, and meanwhile the counter weight installing efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of excavators and components thereof, in particular to an excavator with a counterweight positioning detection device and a counterweight installation method. Background technique [0002] Construction machinery such as excavators generally need to be equipped with counterweights in order to balance the swing of the machine during operation. [0003] figure 1 Shown is the basic structure of an existing hydraulic excavator, which has a lower traveling mechanism 2, a main platform 3, a working device 4, a counterweight 5, a cab 10, and the like. The main platform 3 can rotate in any direction on the lower traveling mechanism 2. The main platform 3 is equipped with a working device 4, a cab 10, a counterweight 5, etc., and the working device 4 is located at the front end of the excavator. The rear end of 3 is equipped with counterweight 5. [0004] Such as figure 2 Shown is a schematic structural diagram o...
