Embodiment 1

[0051] see Figure 1-6 , a suspension weight inclinometer, which includes a hoisting motor 1, a hoisting tube 2 of the hoisting motor 1 is wound with a steel wire rope 3, and the steel wire rope 3 passes through a fixed pulley 5 fixed on the top of the support platform 4, the The middle part of the support platform 4 is equipped with a buoyant device 6, and the steel wire rope 3 passes through the buoyant device 6, and the end of the steel wire rope 3 is connected with a wire hanging device 9, and the wire hanging device 9 is located in the inside of the hole to be measured 10, and the hole to be measured 10 The inlet position is provided with a measuring device 7 . Through the above-mentioned structure, the lower part of the line hanging device 9 can be smoothly inserted into the inside of the hole 10 to be measured, and at the same time, the diameter of the steel tape ruler spring 905 on the line hanging device 9 can be adjusted so that it can adapt to holes to be measured w...

Embodiment 2

[0058] The method for measuring the inclination of the aperture using a suspended weight inclinometer comprises the following steps:

[0059] 1) Install the support platform 4, build the measurement platform, and build the measurement platform directly above the hole to be measured 10 after the drilling, wherein the height of the support platform 4 from the hole to be measured 10 is 2m;

[0060] 2) Install the buoy device 6, place the outer cylinder 601 in the steel hoop 405 of the support platform 4, keep the center of the outer cylinder 601 consistent with the axis line of the steel hoop 405, and fill the inside of the outer cylinder 601 with water 11, and make the inner cylinder 604 float on the water 11;

[0061] 3) adjust the diameter of the line hanging device 9 to match the aperture of the hole 10 to be measured, and ensure that it can pass through the aperture 10 to be measured smoothly,

[0062] 4) Hang the steel wire rope 3, pass the stainless steel wire rope 3 with...

Abstract

The invention relates to a suspension type counter weight clinometer and a measurement method. The suspension type counter weight clinometer comprises a winch motor, wherein a steel wire rope winds a winch barrel of the winch motor and penetrates through a fixed pulley fixed at the top of a supporting platform; a floating barrel device is mounted in the middle of the supporting platform; the steel wire rope passes through the floating barrel device; a linear vertical suspension device is connected with the tail end of the steel wire rope and is located in a hole to be detected; and a measuring device is located at an inlet position of the hole to be detected. The clinometer provided by the invention can be used for carrying out high-frequency and high-precision detection in drilling construction with very high perpendicularity requirements; and an efficient and high-precision perpendicularity detection device, which is convenient to mount, has accurate and reliable data and can meet real-time detection requirements, can be provided for a drilling construction site through the clinometer.

Description

technical field [0001] The invention relates to a perpendicularity measuring device and a measuring method, which are mainly used for measuring the verticality (inclination) of a borehole, and in particular to a combined measuring instrument with a suspension device for measuring the inclination of a borehole. Background technique [0002] Verticality is an important index that often needs to be measured during drilling construction. The quality of verticality directly affects the construction quality of drilling. Especially in water conservancy and hydropower dam safety monitoring projects, various types of boreholes will be encountered, such as vertical holes, inverted holes, bimetallic standard drilling, temperature measuring steel pipe standard drilling, etc. These drilling holes are mainly used for installation For precision monitoring equipment, the effective diameter of the borehole is required to be between 150 and 400mm, and the requirement for verticality is very h...
