Description

Technical Field

[0001] This utility model relates to the field of exploration device technology, specifically to a comprehensive logging instrument depth measurement device. Background Technology

[0002] Exploration is one of the important working methods in engineering geological exploration. Engineering geological exploration includes geophysical exploration, drilling, and pit exploration. Drilling is an important means of obtaining accurate geological data below the surface in engineering geological exploration. During the exploration process, a comprehensive logging instrument depth measurement device is required to record the drilling depth data.

[0003] Chinese patent provides a comprehensive logging depth measurement device with small error, publication number CN216110691U, which includes a base, a vertical shaft is provided on the left side of the top of the base, a rotary device is sleeved on the bottom of the surface of the vertical shaft, and a connecting plate is sleeved on the surface of the vertical shaft and located on the top of the rotary device.

[0004] The above-mentioned device extends and lowers the wire rope by lifting the vertical shaft. Under the gravity of the load block, the wire rope moves downward. Since the top of the wire rope and the left side of the first pulley are in the same vertical and horizontal direction, the data of the water tap moving downward recorded by the logging instrument is accurate.

[0005] However, calculating well depth by converting the number of rotations of the logging instrument into the drill bit depth is a relatively simple method. It is difficult to ensure that the wire rope is tightly fitted, and the pulley is prone to slippage during rotation. This may result in the calculated number of rotations being greater than the actual displacement. In addition, the presence of mud, rock cuttings, and other debris at the drilling site exposes the wire rope and pulley components, making them susceptible to interference from these debris and affecting the stability of the measurement. Utility Model Content

[0006] The purpose of this invention is to provide a comprehensive logging instrument depth measurement device that can effectively solve the problems in the background technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

Two pulleys are mounted on the top of the base away from the vertical axis via a support plate. The end of the steel wire rope body away from the discharge pipe is slidably connected to the surface of the two pulleys. The steel wire rope body extends to the bottom of one of the pulleys. A load-bearing block is connected to the end of the steel wire rope body away from the discharge pipe. Mounting seats are fixedly installed on the load-bearing block near the wire rope body's inlet position and on the top and side of the transparent protective cover. Limiting blocks are threadedly installed on the top of the mounting seats via connecting bolts. The steel wire rope body passes through several limiting blocks.

[0010] Preferably, the inner wall of the limiting block is fitted with the outer ring of the wire rope body, and the wire rope body and the limiting block are slidably connected, and a discharge port is provided on one side of the limiting block.

[0011] Preferably, the pulley two is rotatably mounted on the front end of the support plate via a rotating shaft, and a transparent protective cover two that is compatible with the pulley two is installed on the top end of the support plate by fixing bolts.

[0012] Preferably, a bearing housing is sleeved at the center of the shaft of the second pulley, and a logging instrument is sleeved on the surface of the bearing housing.

At the same time, its transparent setting can avoid personnel observation and facilitate the improvement of measurement stability.

[0017] By setting a limit block in conjunction with the wire rope body, the position of the wire rope body can be restricted during measurement to reduce the probability of it detaching from pulley one or pulley two. At the same time, the outer ring of pulley one and pulley two is provided with anti-slip protrusions and anti-slip grooves, which can further increase the friction with the wire rope body, reduce the probability of slippage, and facilitate the improvement of the accuracy of measurement data.

[0023] 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.

[0024] Example 1

[0025] Combination Figures 1-4 A comprehensive logging depth measurement device includes a base 1, a vertical shaft 2 is provided on one side of the base 1, a connecting plate 4 is sleeved on the outer ring of the vertical shaft 2 at the center, a drain pipe 3 is connected to the top of the vertical shaft 2 through a faucet, and scale blocks 5 are provided on both sides of the top of the connecting plate 4. A transparent protective cover 6 is installed on the side of one of the scale blocks 5 away from the vertical shaft 2 by fixing bolts.

[0026] See Figure 2 and Figure 3Furthermore, a pulley 12 is rotatably mounted on the side of the scale block 5 away from the vertical axis 2 and below the transparent protective cover 6 via a bearing. A steel wire rope body 10 is provided on the outer ring of the pulley 12. One end of the steel wire rope body 10 is connected to the discharge pipe 3. Two pulleys 24 are mounted on the top of the base 1 away from the vertical axis 2 via a support plate 13. The end of the steel wire rope body 10 away from the discharge pipe 3 is slidably connected to the surface of the two pulleys 2 14 respectively. The steel wire rope body 10 extends to the bottom of one of the pulleys 2 14, and the steel wire rope body 10 is away from the discharge pipe 3. One end of the pipe 3 is connected to a load block 11. The load block 11 is fixedly installed with mounting bases 7 near the inlet position of the wire rope body 10 and the top and side positions of the transparent protective cover 6. The top of the mounting base 7 is threaded with a limit block 9 through a connecting bolt 8. The wire rope body 10 passes through several limit blocks 9. The inner wall of the limit block 9 fits against the outer ring of the wire rope body 10, and the wire rope body 10 and the limit block 9 are slidably connected. A sludge discharge port is provided on one side of the limit block 9. A bearing seat is sleeved at the shaft of the pulley 2 14, and a logging instrument is sleeved on the surface of the bearing seat.

[0027] Specifically, during measurement, the wire rope body 10 can be extended and extended by lifting the vertical shaft 2 according to existing technology. Under the gravity of the load block 11, the wire rope body 10 moves downward, causing it to slide on the surface of pulley 12. Subsequently, the wire rope body 10 drives pulley 2 14 to rotate. Since the shaft of pulley 2 14 is connected to the logging instrument through the bearing seat, the rotation of pulley 2 14 can drive the logging instrument to rotate. Therefore, the data of downward movement that the logging instrument can record can be converted into the drill bit depth to calculate the well depth.

[0028] Furthermore, when the wire rope body 10 rotates at pulley 14 and pulley 12, the position of the wire rope body 10 can be restricted and guided by the limiting block 9 to prevent the wire rope body 10 from detaching from pulley 12 or pulley 14, thereby improving measurement accuracy. At the same time, the inner ring of the limiting block 9 is in contact with the outer ring of the wire rope body 10, so that when the wire rope body 10 contacts the limiting block 9, the limiting block 9 can scrape off the mud, rock debris and other impurities adhering to the wire rope body 10, avoiding the influence of too many impurities on the measurement. Moreover, the limiting block 9 can be detachably installed at the mounting base 7 by the connecting bolt 8, and can be replaced after the limiting block 9 wears out after long-term use.

[0029] Example 2

[0030] See Figure 2 and Figure 4Furthermore, based on Embodiment 1, the pulley 2 14 is rotatably mounted on the front end of the support plate 13 via a rotating shaft. The top of the support plate 13 is fitted with a transparent protective cover 2 16 that is compatible with the pulley 2 14 via fixing bolts. The outer walls of the pulley 1 12 and the pulley 2 14 are provided with anti-slip protrusions, and the outer rings of the pulley 1 12 and the pulley 2 14 are provided with several equidistant anti-slip grooves 15. The transparent protective cover 1 6 and the transparent protective cover 2 16 are made of polycarbonate material, and an adjustment gap is left between the transparent protective cover 1 6, the transparent protective cover 2 16 and the wire rope body 10.

[0031] Specifically, the transparent protective cover 16 and transparent protective cover 26 can shield and protect pulley 24 and pulley 12, reducing the probability of mud, rock cuttings and other impurities generated during drilling adhering to pulley 24 and pulley 12, thus preventing them from causing significant interference with measurement accuracy. In addition, the outer rings of pulley 12 and pulley 24 are provided with anti-slip protrusions and anti-slip grooves 15, which can increase the friction coefficient when in contact with the wire rope body 10, thereby reducing the probability of slippage and avoiding significant impact on measurement accuracy.

[0032] In actual operation, during measurement, the wire rope body 10 can be extended and extended by lifting the vertical shaft 2 according to existing technology. Under the gravity of the load block 11, the wire rope body 10 moves downward, causing it to slide on the surface of pulley 12. Subsequently, the wire rope body 10 drives pulley 2 14 to rotate. Since the shaft of pulley 2 14 is connected to the logging instrument through the bearing seat, the rotation of pulley 2 14 can drive the logging instrument to rotate. Therefore, the data of downward movement that the logging instrument can record can be converted into the drill bit depth to calculate the well depth.

[0033] Furthermore, when the wire rope body 10 rotates at pulley 14 and pulley 12, the position of the wire rope body 10 can be restricted and guided by the limiting block 9 to prevent the wire rope body 10 from detaching from pulley 12 or pulley 14, thereby improving measurement accuracy. At the same time, the inner ring of the limiting block 9 is in contact with the outer ring of the wire rope body 10, so that when the wire rope body 10 contacts the limiting block 9, the limiting block 9 can scrape off the mud, rock debris and other impurities adhering to the wire rope body 10, avoiding the influence of too many impurities on the measurement. Moreover, the limiting block 9 can be detachably installed at the mounting base 7 by the connecting bolt 8, and can be replaced after the limiting block 9 wears out after long-term use.

[0034] The transparent protective cover 16 and transparent protective cover 26 can shield and protect pulley 24 and pulley 12, reducing the probability of mud, rock cuttings and other impurities generated during drilling adhering to pulley 24 and pulley 12, thus preventing them from causing significant interference with measurement accuracy. In addition, the outer rings of pulley 12 and pulley 24 are provided with anti-slip protrusions and anti-slip grooves 15, which can increase the friction coefficient when in contact with the wire rope body 10, thereby reducing the probability of slippage and avoiding significant impact on measurement accuracy.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
