[0025] 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.
[0026] Please see Figure 1-3 The present invention provides the following technical solution:
[0027] A measuring device for geological exploration includes an upper V-shaped frame 2, a lower V-shaped frame 1, and a ring seat 6. Three upper V-shaped frames 2 and three lower V-shaped frames 1 are provided. A height adjustment component is provided between the upper V-shaped frames 2 and the lower V-shaped frames 1 in the same vertical direction. The height adjustment component includes a first fixed seat 11, a second fixed seat 21, and a lifting motor 111. The first fixed seat 11 is installed on the top surface of the lower V-shaped frame 1, the second fixed seat 21 is installed on the bottom surface of the upper V-shaped frame 1, and the lifting motor 111 is installed between the inner walls of the first fixed seat 11. The output shaft end of the lifting motor 111 is connected to the second fixed seat 21.
[0028] It should be further explained that by fixing the logging instrument between the upper V-frame 2 and the lower V-frame 1, and then adjusting the height distance between the upper V-frame 2 and the lower V-frame 1 according to the length of the logging instrument and the suitable clamping position, the adjustment can be stopped by starting the lifting motor 111 and allowing its output shaft to extend and retract to the appropriate position.
[0029] Rolling components 5 are installed on the outer surfaces of the upper V-frame 2 and the lower V-frame 1. The rolling components 5 include a fixed cylinder 51, a telescopic shaft 52, and rollers 53. Mounting seats are fixed on the outer surfaces of the upper V-frame 2 and the lower V-frame 1. One end of the fixed cylinder 51 is fixed on the mounting seat. The telescopic shaft 52 is slidably disposed between the inner walls of the fixed cylinder 51 by a key connection. A spring is connected between one end of the telescopic shaft 52 and the inner wall of the fixed cylinder 51 (and this end never leaves the fixed cylinder 51). A U-shaped frame is installed on the other end of the telescopic shaft 52. The rollers 53 are installed between the side walls of the U-shaped frame by a shaft connection.
[0030] It should be further explained that by compressing and adjusting the position of the telescopic shaft 52, when it is lowered into the mine, the roller 53 is made to abut against the inner wall of the mine. Thus, through the mutual restraint of multiple sets of rollers 53, the device can drive the logging instrument to move up and down in the mine, thereby reducing the pressure on the mine hoisting cable.
[0031] The upper V-shaped frame 2 and the lower V-shaped frame 1 have the same structure. An adjustment assembly 3 is provided between adjacent upper V-shaped frames 2 or adjacent lower V-shaped frames 1 on the same plane. The adjustment assembly 3 includes a linkage handle 31, a connecting shaft 32, a slider 33, and a screw 34. An inner cavity is formed near the end of both the upper V-shaped frame 2 and the lower V-shaped frame 1. Fixing holes are formed on the top surface of the upper V-shaped frame 2 and the bottom surface of the lower V-shaped frame 1. The screw 34 is arranged along the length of the inner cavity and is rotatable. A rotary motor is connected to one end of the screw 34. The slider 33 slides between the inner walls of the inner cavity. The screw 34 passes through the slider 33 and engages with it via a threaded drive. A connecting bolt (with an electromagnetic arm) is fixed on the top surface of the slider 33. The connecting bolt slides between the inner walls of the fixing hole. One end of the linkage handle 31 (which is made of iron) is rotatably mounted on the connecting bolt. A connecting shaft 32 is provided between two adjacent linkage handles 31. The end of the connecting shaft 32 always slides between the inner walls of the linkage handles 31. The slider 33 has a built-in power supply (not shown in the figure) that powers the connecting bolt. When current flows through the connecting bolt, the connecting bolt and the linkage handle 31 can be connected together by attraction.
[0032] It should be further explained that when adjusting the area formed by the upper V-frame 2 or the lower V-frame 1, the rotary motor is started simultaneously, causing the screw 34 to rotate. Adjacent screws 34 rotate in opposite directions. When adjacent upper V-frames 2 (or lower V-frames 1) approach each other, the screws 34 drive the sliders 33 on them to move closer together, causing the two linkage handles 31 to move closer simultaneously, gradually retracting the end of the connecting shaft 32 into the linkage handle 31. When adjacent upper V-frames 2 (or lower V-frames 1) move away from each other, the screws 34 drive the sliders 33 on them to move away, causing the two linkage handles 31 to move away simultaneously, gradually exposing the connecting shaft 32 from the linkage handle 31. After adjustment, the built-in power supply is activated, current flows through the connecting bolt, generating electromagnetic current, which then fixes the iron linkage handle 31 end with suction.
[0033] Mounting strips are fixedly installed on one side wall of the upper V-frame 2 and the lower V-frame 1, arranged along their V-shaped trajectory. A ring seat 6 is fixedly installed between two mounting strips on the same upper V-frame 2 or lower V-frame 1. An adjusting ring 62 is movably arranged between adjacent ring seats 6 in the same plane. The adjusting ring 62 and the ring seat 6 can be connected as one unit by suction. A movable frame 4 is also provided in the middle position of the ring seat 6. A soft rubber head 41 is threadedly connected to the vertical side wall of the movable frame 4. Linear motors 112 are respectively installed between the inner walls of the fixed seat 11 and the fixed seat 21. The movable frame 4 is arranged in an "L" shape and a connecting block 42 is provided on the movable frame 4. The output shaft end of the linear motor 112 is fixed to the connecting block 42.
[0034] The ring seat 6 has an inner cavity two near both ends. The end of the adjusting ring 62 slides between the inner walls of the inner cavity two that it contacts. A sliding bolt passes through the end of the adjusting ring 62 and also slides between the inner walls of the ring seat 6. An external power supply is also installed on the side wall surface of the ring seat 6. Two vertically arranged positioning strips 61 are installed on both end faces of the ring seat 6. The adjusting ring 62 slides between two adjacent positioning strips 61 on the same side. Silicon steel sheets are embedded on the side wall surface of the positioning strips 61 that contact the adjusting ring 62. The external power supply is connected to the silicon steel sheets through a wire. When current flows through the silicon steel sheets, the adjusting ring 62 and the positioning strips 61 can be fixed by suction.
[0035] It should be further explained that by adjusting the position of the upper V-frame 2 or the lower V-frame 1, the ring seat 6 is adjusted synchronously. After the adjustment is completed, the external power supply is turned on, so that the positioning strip 61 fixes the position of the adjusting ring 62 by suction. Then, the logging instrument is placed between the upper V-frame 2 and the lower V-frame 1. Then, by starting the linear motor 112, the moving frame 4 moves the soft rubber head 41 closer to the logging instrument and clamps it tightly. Then, the device and the logging instrument are placed in the well for testing by the hoisting cable and the rolling assembly 5.
[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
