Description

Technical Field

[0001] This application relates to the field of coal mine production technology, and in particular to a positioning device and a coal mine electromechanical equipment detection system. Background Technology

[0002] Coal mine production requires the use of various mechanical and electrical equipment. As coal production capacity increases, the operating load, complexity, and environmental adaptability requirements of this equipment also rise. Failures in this equipment can lead to shutdowns and production interruptions, and even major safety accidents such as gas leaks and explosions. Through inspection, potential equipment problems can be detected in a timely manner, preventing safety accidents caused by equipment failures and ensuring the safety of workers and the continuity of production processes.

[0003] In related technologies, the above-mentioned equipment needs to be positioned. However, since the sizes of the various devices are different and the positions of the positioning components of the positioning device are not adjustable, different sizes of equipment need to be tested on different positioning devices, which increases the cost for enterprises. Utility Model Content

[0004] This application is made in view of the above-mentioned problems. This application provides a positioning device and a coal mine electromechanical equipment detection system.

[0005] According to one aspect of this application, a positioning device is provided, comprising: The device comprises a fixed base, a drive assembly, a connecting block assembly, and a positioning assembly. The drive assembly is disposed within the fixed base, the surface of which has a guide groove. The drive assembly is connected to the connecting block assembly and drives the connecting block assembly to reciprocate along the guide groove. The positioning assembly includes a power unit, a first connecting rod, a second connecting rod, and a positioning execution unit. The connecting block assembly is disposed at the bottom of the power unit. The power unit is rotatably connected to one end of the first connecting rod and one end of the second connecting rod, respectively. The positioning execution unit is rotatably connected to the other end of the first connecting rod and the other end of the second connecting rod, respectively, for positioning and clamping the device to be positioned.

[0006] Compared with the prior art, in the positioning device provided in this application, the guide groove on the surface of the fixed base can provide a track for the movement of the connecting block assembly and constrain its movement direction. The drive assembly is directly connected to the connecting block assembly, driving the connecting block assembly to reciprocate along the guide groove, thereby enabling the position adjustment of the positioning assembly (such as forward and backward movement) to adapt to devices of different sizes or positions. As the connection hub between the drive assembly and the positioning assembly, the connecting block assembly can transmit the power of the drive assembly and ensure that the movement trajectory of the positioning assembly is consistent with the guide groove, avoiding deviation. The first connecting rod and the second connecting rod can realize the transmission of force and the conversion of direction through rotational connection with the power unit, thereby converting the linear motion of the power unit into the opposite or opposite motion of the positioning execution unit. In the initial state, the drive assembly is in a stationary state, the connecting block assembly is located at one end of the guide groove, the first connecting rod and the second connecting rod are in an extended state, and the positioning execution unit is in a released state. When positioning and clamping the device to be positioned, the drive assembly is activated and drives the connecting block assembly connected to it to move along the guide groove toward the device to be positioned. During this process, the connecting block assembly at the bottom of the power unit drives the power unit to move synchronously until the positioning execution unit reaches the preset clamping position of the device to be positioned. Once the preset clamping position is reached, the power unit pushes one end of the first connecting rod and one end of the second connecting rod outwards (i.e., in the direction of the device to be positioned). Since the other ends of the first and second connecting rods are rotatably connected to the positioning execution unit, the outward movement forces the positioning execution unit to rotate or translate inwards (e.g., move towards each other). When the positioning execution unit contacts the surface of the device to be positioned, the power unit continuously applies pressure to the device by pushing the connecting rods until a clamping state is achieved, completing the positioning. After the positioning task is completed, the power unit stops outputting power to the connecting rods, causing the connecting rods to reset. The positioning execution unit moves outwards to release the device. At this time, the drive assembly drives the connecting block assembly in the direction away from the device to be positioned, bringing the positioning assembly back to its initial position, ready for the next positioning task.

[0007] Based on this, the positioning device provided in this application embodiment can position devices of different sizes, improving compatibility and reducing enterprise costs.

[0008] According to another aspect of this application, a coal mine electromechanical equipment testing system is provided, comprising: The device to be tested and the aforementioned positioning device; the positioning device includes a first positioning plate and a second positioning plate that respectively contact the two sides of the device to be tested.

[0009] Compared with the prior art, the beneficial effects of the coal mine electromechanical equipment detection system provided in this application are the same as those of the above-mentioned positioning device, and will not be elaborated here.

[0010] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

The accompanying drawings are used to provide a further understanding of the embodiments of this application and form part of the specification. They are used together with the embodiments of this application to explain this application and do not constitute a limitation thereof. In the accompanying drawings, the same reference numerals generally represent the same components or steps.

[0012] Figure 1 A schematic diagram of the positioning device according to an embodiment of this application is shown; Figure 2 A schematic diagram of the positioning component according to an embodiment of this application is shown; Figure 3 A cross-sectional view of a positioning device according to an embodiment of this application is shown; Figure 4 A schematic diagram of the structure of the driving component according to an embodiment of this application is shown. Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this application more apparent, exemplary embodiments according to this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0014] Coal mine production requires the use of various mechanical and electrical equipment. As coal production capacity increases, the operating load, complexity, and environmental adaptability requirements of this equipment also rise. Failures in this equipment can lead to shutdowns and production interruptions, and even major safety accidents such as gas leaks and explosions. Through inspection, potential equipment problems can be detected in a timely manner, preventing safety accidents caused by equipment failures and ensuring the safety of workers and the continuity of production processes.

[0015] In related technologies, the above-mentioned equipment needs to be positioned. However, since the sizes of the various devices are different and the positions of the positioning components of the positioning device are not adjustable, different sizes of equipment need to be tested on different positioning devices, which increases the cost for enterprises.

[0016] To address the aforementioned issues, this application provides a positioning device capable of locating devices of different sizes, thereby improving compatibility and reducing enterprise costs. Figure 1 A schematic diagram of the positioning device according to an embodiment of this application is shown. Figure 1As shown, the positioning device includes a fixed base 1, a drive assembly 2, a connecting block assembly 3, and a positioning assembly 4. The drive assembly 2 is located inside the fixed base 1, and the surface of the fixed base 1 is provided with a guide groove 101. The drive assembly 2 is connected to the connecting block assembly 3 and is used to drive the connecting block assembly 3 to reciprocate along the guide groove 101. The positioning assembly 4 includes a power unit 401, a first connecting rod 402, a second connecting rod 403, and a positioning execution unit 404. The connecting block assembly 3 is located at the bottom of the power unit 401. The power unit 401 is rotatably connected to one end of the first connecting rod 402 and one end of the second connecting rod 403, respectively. The positioning execution unit 404 is rotatably connected to the other end of the first connecting rod 402 and the other end of the second connecting rod 403, respectively, and is used to position and clamp the device to be positioned.

[0017] In this embodiment, the guide groove 101 on the surface of the fixed base 1 provides a track for the movement of the connecting block assembly 3, constraining its direction of movement. The drive assembly 2 is directly connected to the connecting block assembly 3, driving the connecting block assembly 3 to reciprocate along the guide groove 101, thereby enabling the position adjustment of the positioning assembly 4 (such as forward and backward movement) to adapt to devices of different sizes or positions. The connecting block assembly 3, as the connection hub between the drive assembly 2 and the positioning assembly 4, can transmit the power of the drive assembly 2 and ensure that the movement trajectory of the positioning assembly 4 is consistent with the guide groove 101, avoiding deviation. The first connecting rod 402 and the second connecting rod 403, through rotational connection with the power unit 401, can realize the transmission of force and the conversion of direction, thereby converting the linear motion of the power unit 401 into the opposite or opposite motion of the positioning execution unit 404.

[0018] It is understood that the rotational connection in this application embodiment is a movable connection through a pin, and is not limited to this. As long as the connected object can be rotated, it is acceptable. Adjustments can be made according to the actual situation, and no limitation is made here.

[0019] In practice, initially, the drive assembly 2 is stationary, the connecting block assembly 3 is located at one end of the guide groove 101, the first connecting rod 402 and the second connecting rod 403 are in an extended state, and the positioning execution unit 404 is in a released state. When the device to be positioned is to be clamped, the drive assembly 2 is activated, driving the connecting block assembly 3 connected to it to move along the guide groove 101 towards the device to be positioned. During this process, the connecting block assembly 3, located at the bottom of the power unit 401, can drive the power unit 401 to move synchronously until the positioning execution unit 404 reaches the preset clamping position of the device to be positioned. Once the preset clamping position is reached, the power unit 401 can push one end of the first connecting rod 402 and one end of the second connecting rod 403 outwards (i.e., in the direction of the device to be positioned). Since the other ends of the first connecting rod 402 and the second connecting rod 403 are rotatably connected to the positioning execution unit 404, the outward movement forces the positioning execution unit 404 to rotate or translate inwards (e.g., move towards each other). When the positioning execution unit 404 contacts the surface of the device to be positioned, the power unit 401 continuously pushes the connecting rod, causing the positioning execution unit 404 to continuously apply pressure to the device to be positioned until a clamping state is achieved, thus completing the positioning. After the positioning task is completed, the power unit 401 stops outputting power to the connecting rod, causing the connecting rod to reset. The positioning execution unit 404 moves outward to release the device. At this time, the drive assembly 2 drives the connecting block assembly 3 in the direction away from the device to be positioned, bringing the positioning assembly 4 back to its initial position, ready for the next positioning task.

[0020] Based on this, the positioning device provided in this application embodiment can position devices of different sizes, improving compatibility and reducing enterprise costs.

[0021] Figure 2 A schematic diagram of the positioning component according to an embodiment of this application is shown. Figure 1 and Figure 2As shown, the positioning execution unit 404 in this embodiment includes a first moving rod 4041, a second moving rod 4042, a positioning structure 4043, and a slider 4044. Slider 4044 is sleeved on the rods of both the first moving rod 4041 and the second moving rod 4042. The power unit 401 has a longitudinal groove, and the slider 4044 is slidably connected to the longitudinal groove. The ends of the first moving rod 4041 near the power unit 401 are rotatably connected to the other end of the first connecting rod 402. The ends of the second moving rod 4042 near the power unit 401 are rotatably connected to the other end of the second connecting rod 403. The first moving rod 4041 and the second moving rod 4042 are inclined. The ends of the positioning structure 4043 are rotatably connected to the other ends of the first connecting rod 402 and the second connecting rod 403, and are also connected to the ends of the first moving rod 4041 and the second moving rod 4042 near the power unit 401.

[0022] It should be understood that the end of the positioning structure 4043 in this embodiment is located at the connection between the other end of the first connecting rod 402 and the end of the first moving rod 4041 near the power unit 401, and is located at the connection between the other end of the second connecting rod 403 and the end of the second moving rod 4042 near the power unit 401.

[0023] In this embodiment, the first moving rod 4041 and the second moving rod 4042 form a sliding pair with the corresponding slider 4044, allowing the slider 4044 to move along the axial direction of the rod body to adapt to different clamping position requirements. Furthermore, since the first moving rod 4041 and the second moving rod 4042 are inclined, they can generate horizontal and vertical force components under the action of the slider 4044, driving the two positioning structures to move towards each other. The slider 4044 serves as the connection hub between the moving rod and the power unit 401, constraining the movement trajectory of the moving rod through a sliding engagement with the longitudinal groove. The positioning structure 4043, through a rotatable connection with the two connecting rods, can convert the inclined movement of the two moving rods into a horizontal translational or rotational clamping action.

[0024] In practice, initially, the power unit 401 does not provide power to other components. The slider 4044 is located at the bottom of the longitudinal groove, and the first moving rod 4041 and the second moving rod 4042 are inclined and extended. When positioning and clamping the device to be positioned, the power unit 401 is activated, pushing the slider 4044 to slide upward along the longitudinal groove. The slider 4044 can drive the first moving rod 4041 and the second moving rod 4042 to move upward in the inclined direction. Due to the inclination of the rods, a horizontal inward component force is generated. During this process, the horizontal component force is transmitted to the positioning structure 4043 through the connecting rod, causing it to gradually approach the device to be positioned. When the positioning structure 4043 contacts the surface of the device to be positioned, the power unit 401 continuously pushes the first connecting rod 402, the second connecting rod 403, and the slider 4044, so that the positioning structure 4043 continuously applies a clamping force to the device to be positioned until the clamping state is achieved, completing the positioning. Once the positioning task is completed, the power unit 401 stops outputting power, causing the slider 4044 to slide downwards along the longitudinal groove. The moving rod moves downwards in the inclined direction, changing the direction of the horizontal force component and driving the corresponding positioning structure to move in the opposite direction. At this time, the positioning structure 4043 separates from the surface of the device to be positioned, and the distance returns to its initial state. It should be understood that the parts involving the drive component 2 during implementation are described above and will not be repeated here.

[0025] As can be seen, the embodiment of this application cleverly transforms the longitudinal power of the power unit 401 into the horizontal clamping force of the positioning structure through the combination of the inclined rod and the slider 4044, achieving efficient force transmission and motion conversion in a compact space, which is especially suitable for the rapid positioning needs of workpieces of different sizes in the inspection of coal mine electromechanical equipment.

[0026] For example, such as Figure 1 and Figure 2 As shown, the positioning structure 4043 in this embodiment includes a first positioning rod 40431, a second positioning rod 40432, a first positioning plate 40433, and a second positioning plate 40434; the other end of the first connecting rod 402 is connected to one end of the first positioning rod 40431, the end of the first moving rod 4041 near the power unit 401 is rotatably connected to one end of the first positioning rod 40431, the other end of the second connecting rod 403 is rotatably connected to one end of the second positioning rod 40432, the end of the second moving rod 4042 near the power unit 401 is connected to one end of the second positioning rod 40432, the other end of the first positioning rod 40431 is connected to the first positioning plate 40433, and the other end of the second positioning rod 40432 is connected to the second positioning plate 40434.

[0027] The first positioning rod 40431 is rotatably connected to the first connecting rod 402, allowing the angle to be changed during clamping to adapt to different clamping requirements. The second positioning rod 40432 works similarly. That is, the rotation of the first connecting rod 402 and the second connecting rod 403 drives the first positioning rod 40431 and the second positioning rod 40432 to rotate synchronously. If the first connecting rod 402 and the second connecting rod 403 swing outwards, the first positioning rod 40431 and the second positioning rod 40432 rotate inwards, causing the first positioning plate 40433 and the second positioning plate 40434 to move towards each other (clamping). If the first connecting rod 402 and the second connecting rod 403 swing inwards, the first positioning rod 40431 and the second positioning rod 40432 rotate outwards, causing the first positioning plate 40433 and the second positioning plate 40434 to move away from each other (releasing). Furthermore, the first positioning rod 40431 and the second positioning rod 40432 are arranged symmetrically to ensure that the clamping forces applied by the positioning plates on both sides are equal in magnitude and opposite in direction, thus preventing the positioning equipment from being shifted by force.

[0028] In practice, in the initial state, the first connecting rod 402 and the second connecting rod 403 are in an extended state (e.g., horizontal), the first positioning rod 40431 and the second positioning rod 40432 are tilted outwards, and the distance between the first positioning plate 40433 and the second positioning plate 40434 is at its maximum, allowing the device to be positioned to be freely placed between them. When the device to be positioned needs to be clamped, the power unit 401 outputs power to push the first connecting rod 402 and the second connecting rod 403 to swing inwards (i.e., rotate upwards around the output end of the power unit 401). As the first connecting rod 402 and the second connecting rod 403 swing inwards, they can drive the first positioning rod 40431 and the second positioning rod 40432 to rotate inwards. During this process, the rotation of the corresponding positioning rods causes the first positioning plate 40433 and the second positioning plate 40434 to translate or rotate towards the device until they contact the device surface and apply clamping force. It should be understood that the parts involving the drive assembly 2 and the first moving rod 4041 and the second moving rod 4042 in the implementation process are described above and will not be repeated here.

[0029] For example, such as Figure 1 and Figure 2As shown, the power unit 401 in this embodiment includes a fixed box 4011, a connecting plate 4012, and a cylinder 4013 disposed in the fixed box 4011. The connecting plate 4012 is disposed at the bottom of the fixed box 4011, and the side of the connecting plate 4012 facing away from the fixed box 4011 is connected to the connecting block assembly 3. Longitudinal sliding grooves are disposed on the outer side walls of both sides of the fixed box 4011. The fixed box 4011 has a through hole at one end facing the positioning execution unit 404 to accommodate the piston rod 40141 of the cylinder 4013. Piston rod 40141 is rotatably connected to one end of the first connecting rod 402 and one end of the second connecting rod 403, respectively. The extension and retraction direction of piston rod 40141 is the same as the extension direction of guide groove 101. One end of the first positioning rod 40431 and the end of the first moving rod 4041 near piston rod 40141 are rotatably connected to the other end of the first connecting rod 402. One end of the second positioning rod 40432 and the end of the second moving rod 4042 near piston rod 40141 are rotatably connected to the other end of the second connecting rod 403. It should be understood that, for clearer illustration of the connection relationships of other components, Figure 1 and Figure 2 The longitudinal groove is omitted in both cases.

[0030] It is understandable that the rotational connection between the first positioning rod 40431, the first moving rod 4041, and the first connecting rod 402 is a hinged connection. For example: One end of the first positioning rod 40431 is welded to the end of the first moving rod 4041 near the piston rod 40141, and a mounting hole is made at the weld overlap to ensure that the axis of the mounting hole passes through the weld area of ​​both. The mounting hole at the weld is fitted with a transition fit or a small clearance fit with the pin to ensure that one end of the first positioning rod 40431 and the end of the first moving rod 4041 near the piston rod 40141 can rotate synchronously with the pin. The other end of the first connecting rod 402 also has a mounting hole, which is fitted with the pin with a clearance fit to ensure that the entire assembly of one end of the first positioning rod 40431 and the end of the first moving rod 4041 near the piston rod 40141 can move relative to the other end of the first connecting rod 402.

[0031] The rotational connection method of the second positioning rod 40432, the second moving rod 4042 and the second connecting rod 403 is the same, and will not be described in detail here.

[0032] The piston rod 40141 is rotatably connected to one end of the first connecting rod 402 and one end of the second connecting rod 403 by a hinge connection. For example: The piston rod 40141 has coaxial mounting holes at one end, the first connecting rod 402 has one end, and the second connecting rod 403 has one end. The pin is fitted with these three mounting holes with clearance.

[0033] As can be seen, drive assembly 2 is responsible for large-range horizontal position adjustment, i.e., coarse adjustment, while cylinder 4013 is responsible for vertical clamping force control, i.e., fine adjustment. The two achieve motion coordination through the consistency of the guide groove 101 and the piston rod 40141, avoiding a single drive source simultaneously bearing the dual load of position adjustment and clamping, thus improving control accuracy and the lifespan of the positioning device. Furthermore, the horizontal linear motion of piston rod 40141 is converted into the horizontal clamping motion of positioning structure 4043 through a combination of two connecting rods and two inclined moving rods, reducing motion conversion losses. Additionally, connecting plate 4012, as the bottom connector of fixed box 4011, can be used to securely mount fixed box 4011 onto connecting plate 4012 via bolts, welding, or other methods, providing rigid support and preventing the fixed box 4011 from shaking or shifting due to the reaction force when cylinder 4013 operates.

[0034] For example, in this embodiment, both the inner sides of the first positioning plate and the inner sides of the second positioning plate are provided with anti-slip layers, which can increase the coefficient of friction between the two positioning plates and the surface of the device to be positioned, thereby improving static friction. This anti-slip layer can be a rubber anti-slip layer or a polyurethane anti-slip layer, and can be adjusted according to actual conditions; no limitation is made here.

[0035] In one alternative embodiment, a lubricating layer is provided on the contact surface between the connecting block assembly and the guide groove in this application embodiment to reduce frictional resistance and improve smoothness of movement. This lubricating layer can be a molybdenum disulfide lubricating layer or other lubricating layers capable of lubrication, and can be adjusted according to actual conditions; no limitation is made here. It should be understood that, in order to more clearly illustrate the connection relationships of other components in the accompanying drawings, the anti-slip layer and lubricating layer are not shown in the figures.

[0036] Figure 3 A cross-sectional view of a positioning device according to an embodiment of this application is shown. Figure 4 A schematic diagram of the structure of the driving component according to an embodiment of this application is shown. Figures 1 to 4As shown, the fixed base 1 in this embodiment includes a base plate 102 with a cavity and a fixed cover 103 disposed on the base plate 102. The drive assembly 2 includes a gear assembly 201, a drive motor 202, a motor shaft 203, and a gear rail assembly 204. The gear assembly 201 is disposed in the cavity, the drive motor 202 is disposed in the fixed cover 103, one end of the motor shaft 203 is connected to the drive motor 202, and the other end of the motor shaft 203 is connected to the gear assembly 201. The gear rail assembly 204 includes a first gear rail 2041 and a second gear rail 2042 distributed along the extension direction of the guide groove 101. The connecting block assembly 3 includes a first connecting block 301, which is connected to the upper surface of the first gear rail 2041. The first gear rail 2041 and the second gear rail 2042 mesh with the gear assembly 201 respectively, and the tooth surfaces of the first gear rail 2041 and the second gear rail 2042 are arranged opposite to each other.

[0037] The base plate 102 with a cavity serves as the basic support structure, accommodating the gear assembly 201 and providing an installation reference. The cavity provides space for the rotation of the gear assembly 201, ensuring that the transmission components are not exposed, thus improving structural compactness and safety. The mounting cover 103 encloses the drive motor 202, protecting it from external environmental interference (such as dust and impacts), while also providing a mounting point for the drive motor 202. The gear assembly 201 receives the rotational power from the motor shaft 203, converting the rotational motion into linear motion of the gear rails through gear meshing. The first gear rail 2041 and the second gear rail 2042 are distributed along the extension direction of the guide groove 101, with their tooth surfaces facing each other (i.e., the teeth face opposite directions). After meshing with the gear assembly 201, they convert the rotational motion of the gear into its own linear reciprocating motion. Because the tooth surfaces of the first gear rail 2041 and the second gear rail 2042 face each other, when the gears of the gear assembly 201 rotate, they simultaneously push the first gear rail 2041 and the second gear rail 2042 to move in opposite directions.

[0038] In practice, if clockwise rotation is the initial direction of rotation, the drive motor 202 starts, driving the gear assembly 201 to rotate clockwise via the motor shaft 203. The teeth of the gear assembly 201 mesh with the first gear rail 2041 and the second gear rail 2042 respectively, pushing the first gear rail 2041 and the second gear rail 2042 to move in opposite directions along the guide groove 101. The first connecting block 301 moves with the first gear rail 2041, driving the fixed box 4011 to move closer to the device to be positioned via the connecting plate 4012. After positioning is completed, the drive motor 202 reverses, and the motor shaft 203 drives the gear assembly 201 to rotate counterclockwise. The gear assembly 201 meshes with the gear rails in the opposite direction, and the first gear rail 2041 and the second gear rail 2042 move in opposite directions, driving the first connecting block 301 and the connecting plate 4012 to move in the opposite direction as well. The fixed box 4011 returns to its initial position along the guide groove 101.

[0039] For example, the gear assembly 201 in this embodiment includes a first gear 2011 and a transmission structure 2012; the transmission structure 2012 includes a connecting shaft 20121, a second gear 20122, and a third gear 20123. The first gear 2011 is sleeved on the motor shaft 203. The two ends of the connecting shaft 20121 are rotatably connected to the top inner wall and the bottom inner wall of the base plate 102, respectively. The second gear 20122 and the third gear 20123 are both sleeved on the connecting shaft 20121. The third gear 20123 is located on the second gear 20121. Below wheel 20122, the second gear 20122 meshes with the first gear 2011, and the third gear 20123 meshes with the first gear rail 2041 and the second gear rail 2042 respectively. The diameter of the second gear 20122 is smaller than the diameters of the first gear 2011 and the third gear 20123. The module of the third gear 20123 is the same as the module of the first gear rail 2041 and the second gear rail 2042. There are two transmission structures 2012 and two gear rail assemblies 204. Both transmission structures 2012 and gear rail assemblies 204 are located on both sides of the first gear 2011.

[0040] The first gear 2011 is mounted on the motor shaft 203, directly receiving power from the motor and driving the second gears 20122 on both sides. The third gear 20123 is coaxially fixed with the second gears 20122 and directly drives the gear rail assembly 204; its module matches the gear rail to ensure smooth meshing and transmission. The first gear rail 2041 and the second gear rail 2042 convert rotational motion into linear motion by meshing with the third gear 20123; their tooth surfaces are arranged oppositely, so that the two gear rails move in opposite directions.

[0041] In practice, the drive motor 202 starts, driving the first gear 2011 to rotate clockwise via the motor shaft 203. Since the diameter of the second gear 20122 is smaller than that of the first gear 2011, the first gear 2011 acts as the driving gear, and the second gear 20122 acts as the driven gear, forming a reduction transmission. The first gear 2011 has a higher rotational speed and lower torque, while the meshing second gear 20122 rotates counterclockwise, reducing its rotational speed but increasing its torque, providing greater thrust for subsequent transmission. Because the second gear 20122 and the third gear 20123 are coaxially driven, the counterclockwise rotation of the second gear 20122 is directly transmitted to the lower third gear 20123 via the connecting shaft 20121, causing the third gear 20123 to rotate counterclockwise. During this process, the third gear 20123 meshes with the first gear rail 2041, pushing the first gear rail 2041 to move in the direction closer to the device to be positioned. At the same time, the third gear 20123 meshes with the second gear rail 2042, pushing the second gear rail 2042 to move in the direction away from the device to be positioned.

[0042] In practical applications, the second gear 20122 and the third gear 20123 are fixed to the connecting shaft 20121 by a flat key. Therefore, when the second gear 20122 rotates, it can drive the connecting shaft 20121 and the third gear 20123 to rotate. Furthermore, mounting holes can be pre-set on the top and bottom inner walls of the base plate 102, and rolling bearings (such as deep groove ball bearings) can be installed in these holes. Both ends of the connecting shaft 20121 are respectively interference-fitted with the inner rings of the bearings, and the outer rings of the bearings are interference-fitted with the mounting holes of the base plate 102. Specific connection methods and steps include, but are not limited to, these and can be adjusted according to actual conditions; they are not limited here.

[0043] For example, in this embodiment, both the number of positioning components 4 and the number of transmission structures 2012 are two. The two positioning components 4 are distributed at both ends of the fixed base 1, and the two transmission structures 2012 are located on both sides of the first gear 2011, so as to realize the synchronous action of the positioning components 4 at both ends by utilizing the steering change of gear meshing and the bidirectional movement of the gear rail. The connecting block assembly in this embodiment also includes a second connecting block 302, which is connected to the upper surface of the second gear rail 2042.

[0044] This application also provides a coal mine electromechanical equipment testing system to reduce the testing cost and difficulty of coal mine electromechanical equipment. The system includes a device to be tested and the aforementioned positioning device; the positioning device includes a first positioning plate and a second positioning plate that respectively contact both sides of the device to be tested.

[0045] In practice, the coal mine electromechanical equipment is placed on the positioning device, employing the double-sided gear transmission structure described earlier. The first and second positioning plates are initially in a loose state. When the positioning task begins, both positioning plates move synchronously towards the center until they are in close contact with the left and right surfaces of the device to be tested, forming a mechanical fixation to prevent displacement of the coal mine electromechanical equipment during testing.
