Abstract
A steel drill rod used for grounding resistance test comprises a rod body and a handle horizontally arranged on the rod body. A lower portion of the rod body is cone-shaped. The steel drill rod used for grounding resistance test is characterized in that the rod body is a threaded rod; and after swelled, a top portion of the rod body is in a wrench opening shape. According to the steel drill rod of the utility model, the rod body is designed into a screw thread structure, so when the steel drill rod is used, the contact area of the steel drill rod and the ground is increased, and therefore, reliability is improved, and further, after swelled, the top portion of the rod body is in a wrench opening shape, such that the steel drill rod has the functions of a wrench, and therefore, it is convenient for a worker to perform disassembly and installation on related fastenings timely.
Description
[technical field]
The utility model belongs to the aid of the charged detection of a kind of electric power facility, especially belongs to a kind of to 35～1000kV powerline pole tower ground resistance test drill rod.
[background technology]
At present, the device of test powerline pole tower ground resistance is made up of resistance detection table, drill rod and the lead-in wire that is wrapped on this drill rod, during use, emits lead-in wire, drill rod is inserted in the soil of reference point and tests.Used drill rod structure is a cylindricality steel pole that has handle in this device, and it is conical that its head is, and in realizing use, there are the following problems for it: the surface of contact with soil behind the insertion soil is little, causes poor reliability.
[summary of the invention]
For solving the problems of the technologies described above, the utility model aims to provide the novel earth resistance drill rod of a kind of structure, and this drill rod has the advantage long-pending big with soil contact.
For achieving the above object, the utility model has adopted following technical scheme: this earth resistance comprise shaft, and level is to the handle that is arranged on this shaft with the structure of drill rod, it is conical that the bottom of described shaft is, and it is characterized in that: described shaft is a threaded rod.
During as preferred concrete enforcement, after expanding, the top of described shaft is the wrench opening shape.
Beneficial effect: compared with prior art, after the utility model is designed to helicitic texture with the shaft of drill rod, has increased the contact area with soil during use, thereby improved reliability.Moreover, after expanding, the top is the wrench opening shape, make it to have possessed the spanner function, and therefore associated fasteners is dismantled for the operating personnel and installation has brought facility in good time.
Below in conjunction with accompanying drawing, be further described by the utility model of embodiment.
[description of drawings]
Fig. 1 is the structural representation of an embodiment of the utility model.
Among the figure: shaft 1, bottom 11, external thread 12, handle 13, wrench opening 14.
[embodiment]
Referring to Fig. 1.Handle 13 levels are to being arranged on the shaft 1, and it is conical that the bottom 11 of described shaft 1 is, and has external thread 12 on the shaft 1.After expanding, drill rod shaft 1 top is wrench opening 14, so that the operating personnel is used for dismounting and installation to securing member in good time.
Claims (2)
1. an earth resistance drill rod comprises shaft (1), and level is to the handle (13) that is arranged on this shaft (1), and it is conical that the bottom (11) of described shaft (1) is, and it is characterized in that: described shaft (1) is a threaded rod.
2. drill rod as claimed in claim 1 is characterized in that: be wrench opening (14) shape after expand at the top of described shaft (1).
