Description

Technical Field

[0001] The utility model relates to the field of benchmark pole centralizers, in particular to a benchmark pole ball centralizer for deep bedrock benchmarks. Background Art

[0002] Bedrock markers are leveling points buried in stable bedrock. In areas covered with loose strata, in order to more accurately measure ground subsidence, the markers buried in stable bedrock through the covering layer are directly connected to the ground and protected as relatively stable bedrock leveling points. Deep bedrock markers are often used in deep mining, geological exploration, and geological surveying to mark specific locations, depths, or locations, helping surveyors to accurately measure and locate the work area.

[0003] However, traditional external bedrock marker centralizers are mostly roller-type centralizers, which are low in strength and are not suitable for deep markers. When used for deep marker fixation, the rollers will shift when sliding over a long distance due to friction, poor wear resistance, and unreasonable structural design, which will affect the centering accuracy of the marker during deep marker construction. When operating in an underground environment for a long time, it is easily affected by the underground environment and pollution, which reduces the stability of the centralizer's mark, thereby affecting the stability and accuracy of the marker fixation. In addition, the roller-type centralizer uses a center sleeve, and the material used for the center sleeve is mostly copper or stainless steel, which is relatively expensive.

[0004] Therefore, those skilled in the art provide a deep bedrock benchmark ball centralizer to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a ball-type centralizer for a benchmark of deep bedrock marker is proposed. Compared with most traditional benchmark centralizers of deep bedrock markers, the benchmark centralizer of the deep bedrock marker is provided with multiple legs, and a universal wheel bull's eye bearing is provided on each leg, so that the centralizer can be flexibly moved in any direction, thereby making the centralizer more stable and smooth when placed, which improves the convenience of using the centralizer. The universal wheel bull's eye bearing has good wear resistance and corrosion resistance, which can improve the stability of the centralizer when used in a working environment thousands of meters underground. The simple structural design makes the strength of the centralizer higher, and no center sleeve is required, so that the cost of the centralizer is reduced.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] Furthermore, a main pole is fixedly connected to the inner wall of the main body;

[0010] Through the above technical solution, the centralizer can adjust the position of the main pole so that the main pole is located in a relatively central position.

[0011] Furthermore, a fixing groove is provided at the center of the outer wall of the support leg away from the main body;

[0012] Through the above technical solution, the fixing groove is provided so that the universal wheel bull's eye bearing can be fixed on the supporting leg.

[0013] Furthermore, a placement groove is provided at the center of the outer wall of the universal wheel bull's eye bearing on a side away from the supporting leg;

[0014] Through the above technical solution, a plurality of parts can be placed on the universal wheel bull's eye bearing by providing the placement groove.

[0015] Furthermore, a plurality of balls are arranged on one end of the inner wall of the placement groove close to the universal wheel bull's eye bearing;

[0016] Through the above technical solution, the rolling ball is provided to assist the rolling ball in rotating, so that the rolling ball rotates more smoothly.

[0017] Furthermore, an end of the inner wall of the placement groove away from the universal wheel bull's eye bearing is fixedly connected to a limited position fixing ring;

[0018] Through the above technical solution, the ball and the roller are limited in the placement groove by setting a limiting fixing ring, thereby reducing the possibility of the ball and the roller falling off.

[0019] Furthermore, a rolling ball is arranged at the center of the placement groove;

[0020] Through the above technical solution, the rolling ball is arranged so that the universal wheel bull's eye bearing can rotate in multiple directions.
