Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0018] refer to Figure 1-2 , a temporary electrical grounding device for construction machinery, including a base 1, a metal ground rod 2 is vertically provided on the lower side of the base 1, and the lower end of the metal ground rod 2 is in the shape of a 30-degree cone, which is convenient for the metal ground rod 2 Inserted into the ground, the upper end of the metal ground rod 2 is fixedly connected to the base 1. The base 1 is provided with a plurality of fixing mechanisms 3 for fixing. The metal ground rod 2 can be reinforced in the ground through the fixing mechanisms 3. The fixing mechanism 3 includes The second threaded hole provided on the base 1, the se...

The invention discloses an electrical grounding device temporarily used for a building machine. The electrical grounding device comprises a base, wherein a metal grounding rod is vertically arranged at a lower side of the base, one end of a rotation shaft is rotatably connected with one of side plates in a gantry support, the other end of the rotation shaft penetrates through the other side plateof the gantry support and is coaxially and fixedly connected with a rotating handle mechanism, a limitation mechanism is arranged on the gantry and is used for limiting the rotating handle mechanism to rotate, a telescopic rod is vertically arranged at one side of the base, a rubber set is fixedly connected to a lower end of the telescopic rod, a metal block is fixedly connected to an upper end ofthe telescopic rod, a metal clamping block is horizontally arranged at one side, far away from the telescopic rod, of the metal block, and a first thread hole is vertically formed in the metal blockand is matched with a first thread rod. The electrical grounding device is reasonable in structure, and the building machines at different heights can be connected with ground and protected and are conveniently clamped at optimal positions; and meanwhile, grounding help can be performed by employing a support state during grounding protection on the building machine which can be clamped at no place.
Description
technical field [0001] The invention relates to the technical field of construction machinery, in particular to a temporary electrical grounding device for construction machinery. Background technique [0002] With the development of the construction industry, there are more and more large buildings such as high-rise and super high-rise buildings. The construction period is restricted during the construction process, and the number of construction machinery invested is increasing. These electrical equipment and machinery must be grounded during use. , to prevent personnel from electric shock accidents. The existing grounding device has a fixed structure and cannot adapt to construction machines of different heights, and at the same time, some construction machines are inconvenient to fix the grounding device. [0003] For this reason, we propose a temporary electrical grounding device for construction machinery to solve the above problems. Contents of the invention [00...
