Abstract
The utility model discloses a prism counterweight rod, which comprises a connecting part, a rod part and a cone part, wherein the upper end of the rod part is provided with the connecting part, the lower end is provided with the cone part, and the counterweight rod is in threaded connection with a prism through the connecting part; the light-emitting diode lamp is characterized in that the rod part and the cone part are integrally formed, the total mass of the rod part and the cone part is 1000g, and red and white reflective strips are arranged on the surface of the rod part. After the utility model is used, the influence of the tunnel wind current on the measurement accuracy is obviously improved, and the requirement of the measurement accuracy can be met at one time no matter the main air inlet tunnel or the local ventilation tunnel; the whole portable, easy operation can satisfy the mine and realize the target of high efficiency, high yield.
Description
Technical Field
The utility model belongs to the technical field of surveying instrument technique and specifically relates to a prism counterweight rod is related to.
Background
During construction measurement, a prism is often used, and the prism leveling is an important step before use; the prism is often unstable when being held by hand, the bubble is difficult to center, if a proper counterweight is added at the lower end of the prism, the gravity center moves downwards, the stability can be improved, and the data error is reduced.
However, the original weight rod part of the measuring prism is only 500g, and the measuring prism needs to be matched with a screw rod and a nylon cord to be lengthened for use during underground measurement, so that the measuring prism is easy to deform and bend and inconvenient to carry, and the lengthened weight cannot be carried out during operation in a part of space limited areas, so that the measuring precision and the working efficiency are severely limited.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide a prism counterweight rod to solve the problem mentioned in the background technology.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a prism counterweight rod comprises a connecting part, a rod part and a cone part, wherein the upper end of the rod part is provided with the connecting part, the lower end of the rod part is provided with the cone part, and the counterweight rod is in threaded connection with a prism through the connecting part; the rod part and the cone part are integrally formed, and the total mass of the rod part and the cone part is 1000 g.
Preferably, the surface of the rod part is provided with red and white reflective strips, so that a target can be conveniently found during measurement.
Preferably, the rod part is round steel with the diameter of 30 mm.
More preferably, the tapered part is a cone with a bottom surface diameter of 30 mm.
More preferably, the connecting part is a screw rod with the diameter of 6 mm.
More preferably, the length of the connecting part is 10mm, the length of the rod part is 300mm, and the length of the cone part is 80 mm.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model is convenient to carry and simple to operate; the overall stability is strong, the installation is simple and random, the labor intensity of measurement is reduced, the working time is saved, and the goals of high efficiency and high yield of a mine can be met; accidental errors caused by poor prism stability are eliminated, and therefore the purpose of accurate penetration is achieved.
Use the utility model discloses afterwards, the influence of tunnel air current to measurement accuracy obtains obviously improving, no matter be main air inlet tunnel or local ventilation tunnel can both once only reach measurement accuracy's requirement.
