Description

Technical Field

[0001] The utility model relates to the technical field of wellbore detection tooling, and particularly relates to a manufacturing precision detection tooling for nuclear waste storage wells. Background Art

[0002] A wellbore refers to a vertical or inclined project drilled from the ground to an ore body in underground mining or underground engineering construction. A vertical project is called a vertical shaft, and an inclined project is called an inclined shaft. When in production, the inner diameter size of the wellbore needs to be detected. Generally, a lifting trolley is used for detection. The test simulation piece is lifted to an appropriate height, the wheels of the simulation piece are stuck to the lower part, and the two support plates are controlled by a pull rope to pass through the assembly. One assembly needs to pass through 3 times to ensure that each support plate abuts against the simulation piece, and no jamming occurs during the test to be qualified.

[0003] When the existing manufacturing precision detection tooling for nuclear waste storage wells is in use, it is inconvenient to adjust the height of the detection table for placing the wellbore. From the perspective of operation intensity, the wellbore of a nuclear waste storage well usually has the characteristics of large diameter and high weight, and its single-section length can reach several meters. When detecting wellbores of different specifications, if the height adjustment depends on primitive methods such as manual rockers or bolt jacking, multiple operators are often required to cooperate, and the single adjustment takes a long time, thus affecting the convenience of actual operation and detection.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 The present invention provides a precision testing fixture for the manufacturing of nuclear waste storage wells, including a base 1.

[0028] Reference Figure 1 , Figure 2 and Figure 3 As shown, a guide plate 2 is fixedly connected to the outer wall of the base 1, and a lifting mechanism 3 is fixedly connected to the outer wall of the base 1. The lifting mechanism 3 includes a hydraulic rod 31 fixedly installed on the top of the base 1. A movable plate 32 is fixedly connected to the output end of the hydraulic rod 31. A guide groove 33 is opened inside the movable plate 32. A sliding groove 34 is opened inside the movable plate 32. An L-shaped support rod 35 is movably connected inside the movable plate 32. A testing platform 36 is fixedly connected to the top of the L-shaped support rod 35. A guide rod 4 is fixedly connected to the top of the base 1. Both the guide plate 2 and the guide groove 33 are T-shaped. The movable plate 32 forms a sliding structure with the guide plate 2 through the guide groove 33. The movable plate 32 forms a sliding structure with the L-shaped support rod 35 through the sliding groove 34. The testing platform 36 is an open-hole design. The testing platform 36 forms a sliding structure with the guide rod 4. The guide rod 4 is symmetrically arranged about the central axis of the base 1.

[0029] By activating the hydraulic rod 31, under the action of the guide groove 33, the movable plate 32 can slide stably along the guide plate 2, driving the L-shaped support rod 35 to slide along the slide groove 34, so that the detection platform 36 fixedly connected to the top of the L-shaped support rod 35 slides up and down along the guide rod 4, thereby adjusting the wellbore lifting and lowering.

[0030] Reference Figure 1 , Figure 4 and Figure 5 As shown, a shelf 5 is fixedly connected to the top of the testing platform 36, and a limiting mechanism 6 is fixedly connected to the outer wall of the testing platform 36. The limiting mechanism 6 includes a side plate 61 fixedly installed on the outer wall of the testing platform 36. A threaded groove 62 is opened inside the side plate 61, and a bolt 63 is movably connected inside the threaded groove 62. One end of the bolt 63 is movably connected to a limiting plate 64. A through hole 65 is opened inside the limiting plate 64, and a limiting rod 66 is fixedly connected to one side of the limiting plate 64. The side plate 61 is threadedly connected to the bolt 63 through the threaded groove 62, and the bolt 63 forms a rotating structure with the limiting plate 64 through the through hole 65. The side plate 61 is designed with an open hole, and the side plate 61 and the limiting rod 66 form a sliding structure.

[0031] By placing the well casing on the placement plate 5 and rotating the bolt 63, one end of the bolt 63 can be rotated along the through hole 65 because the bolt 63 is threaded to the side plate 61 through the threaded groove 62, which drives the limiting plate 64 to move. This causes the limiting rod 66 to slide stably along the side plate 61, so that the two limiting plates 64 press against the outer wall of the well casing, thus limiting the well casing. By passing the detection component through the well casing three times in a row, if all three times are unobstructed, then the well casing size is qualified.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
