Description

Technical Field

[0001] This application relates to the field of coal mine operation technology, and in particular to a monorail hoist track connection positioning device. Background Technology

[0002] In coal mining operations, monorail transportation is the mainstream method of transporting mine materials. The stable connection of monorail tracks is directly related to the smooth operation of transportation. The precise alignment of adjacent monorail tracks is a key link in the track connection process, which has an important impact on the subsequent track fixing and installation as well as the overall transportation safety.

[0003] To ensure the proper alignment of adjacent monorail tracks, current technologies often employ manual manipulation of the tracks. Operators manually adjust the positions of two adjacent monorail tracks to align them before proceeding with subsequent fixing operations. In some scenarios, simple tools such as crowbars are also used to assist in the adjustment.

[0004] However, the manual twisting and simple tool-assisted alignment method not only requires the cooperation of multiple people, resulting in low operational efficiency, but also makes it difficult to guarantee the accuracy of the monorail alignment, which can easily lead to track connection deviations. In addition, the complex mining environment poses high safety hazards during manual operation, and cannot meet the needs of efficient and safe track replacement operations in mines.

[0038] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application.

[0039] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0040] The terms "first," "second," "third," etc., are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms can be used interchangeably where appropriate.

[0041] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0042] In underground coal mine transportation operations, the monorail track connection device is a key component ensuring the stable operation of the track system. It is widely used in production processes such as material transportation and personnel transport in mines, and there are clear requirements for the accuracy, reliability, and installation efficiency of the monorail track connection. The monorail track connection device typically includes core components such as a track clamping mechanism, a connecting rod adjustment mechanism, and a fastening control mechanism. Among these, the quick-alignment structure is crucial for ensuring smooth installation of track bolts and improving connection efficiency.

[0043] From the technical requirements of monorail connection, the monorail must maintain precise alignment of the holes during the docking process. This is to ensure the axes of the connection holes coincide through rapid correction, guaranteeing the smooth passage of the bottom bolts and preventing bolt installation difficulties and low work efficiency caused by track misalignment. The alignment accuracy of the monorail joint directly affects the efficiency and safety of the connection operation.

[0044] In current monorail connection operations, manual prying or direct hammering is commonly used for correction. When misalignment occurs at the monorail joint, workers must correct it using manual pry bars or hammers. This method is not only physically demanding and inefficient, but also poses a safety hazard of tools slipping and causing injury. This approach not only makes it difficult to guarantee the accuracy of monorail correction, leading to significant safety risks, but may even cause secondary damage to the track due to improper correction.

[0045] To solve the problem of rapid alignment of monorail track connections, see [reference needed]. Figure 1 This application provides a monorail track connection alignment device in some embodiments, see [link to relevant documentation]. Figure 1 It includes: a first link 1 and a second link 2 that are cross-hinged, a first jaw 3, a second jaw 4, a first lead screw 5, a second lead screw 6, and a ratchet mechanism 7.

[0046] The first connecting rod 1 is the main support structure of the device, made of steel plate and steel pipe. A first jaw 3, welded from steel plate, is hinged to one end of the first connecting rod 1. The first jaw 3 is used to clamp one side of the monorail track. The second connecting rod 2 is also the main support structure of the device, made of steel plate and steel pipe. The second connecting rod 2 is cross-hinged with the first connecting rod 1. A second jaw 4, welded from steel plate, is hinged to one end of the second connecting rod 2. The second jaw 4 is used to clamp the other side of the monorail track. The first jaw 3 and the second jaw 4 are located on the same side of the cross-hinged connection between the first connecting rod 1 and the second connecting rod 2.

[0047] The first lead screw 5 is a transmission component. The first lead screw 5 is hinged to the end of the first connecting rod 1 away from the first jaw 3. The surface of the first lead screw 5 is machined with threads.

[0048] The second lead screw 6 is a transmission component. The second lead screw 6 is hinged to the end of the second connecting rod 2 furthest from the second jaw 4. The surface of the second lead screw 6 is threaded. The thread direction of the second lead screw 6 is opposite to that of the first lead screw 5.

[0049] The ratchet mechanism 7 is the driving component. The two ends of the ratchet mechanism 7 are respectively fitted onto the end of the first lead screw 5 furthest from the first connecting rod 1 and the end of the second lead screw 6 furthest from the second connecting rod 2. The ratchet mechanism 7 is used to drive the first lead screw 5 and the second lead screw 6 to produce linear motion.

[0050] It should be noted that when the monorail track alignment device is in operation, the operator places the device between two adjacent monorail tracks. The first jaw 3 and the second jaw 4 are located on opposite sides of the monorail tracks. Initially, the angle between the first link 1 and the second link 2 is large, and the distance between the first jaw 3 and the second jaw 4 is greater than the width of the monorail track. The operator operates the ratchet mechanism 7. The ratchet mechanism 7 drives the first lead screw 5 and the second lead screw 6 to produce opposing linear motion. The linear motion of the first lead screw 5 and the second lead screw 6 pushes the first link 1 and the second link 2 to rotate around the cross hinge point. The angle between the first link 1 and the second link 2 gradually decreases. The first jaw 3 and the second jaw 4 move towards the monorail track synchronously under the action of the first link 1 and the second link 2. After the first jaw 3 and the second jaw 4 contact the surface of the monorail track, the operator continues to operate the ratchet mechanism 7. The ratchet mechanism 7 continues to drive the first lead screw 5 and the second lead screw 6 to produce opposing linear motion. The first jaw 3 and the second jaw 4 use continuously increasing clamping force to push the two monorail tracks into an aligned position. When the distance between the first jaw 3 and the second jaw 4 reaches its minimum value, the monorail tracks are in a fully aligned state. At this time, the operator can install the bottom bolts of the monorail tracks.

[0051] As can be seen from the above technical solution, the monorail connection alignment device provided in this embodiment achieves mechanical transmission by driving the first lead screw 5 and the second lead screw 6 through the ratchet mechanism 7. This allows for operation by a single person, solving the problem of low efficiency associated with manual twisting. The device provides controllable displacement through the first lead screw 5 and the second lead screw 6, and achieves adjustment by combining the cross-hinged first connecting rod 1 and the second connecting rod 2, thus solving the problem of poor accuracy associated with manual twisting. The device adopts a mechanized clamping method, keeping the operator away from the direct contact point. The transmission characteristics of the ratchet mechanism 7 maintain stable clamping force, solving the problem of poor safety associated with manual twisting. This device improves operational efficiency while ensuring track alignment accuracy and operational safety.

[0052] In some embodiments, see Figures 1-3 The first connecting rod 1 and the second connecting rod 2 are respectively provided with a coaxial first hinge hole 11 and a second hinge hole 21 at their cross-hinged connection. The first hinge hole 11 is located at the cross-hinged position of the first connecting rod 1. The second hinge hole 21 is located at the cross-hinged position of the second connecting rod 2. The first hinge hole 11 and the second hinge hole 21 have the same diameter. A first pin passes through the first hinge hole 11 and the second hinge hole 21.

[0053] It should be understood that the first link 1 and the second link 2 are cross-hinged together by a first pin. The first pin passes through the first hinge hole 11 and the second hinge hole 21 and is secured by a nut or locked with a pin. The first link 1 and the second link 2 can rotate relative to each other around the first pin. The coaxial arrangement of the first hinge hole 11 and the second hinge hole 21 ensures that the rotation axes of the first link 1 and the second link 2 coincide. The rotation of the first link 1 and the second link 2 around the first pin enables the synchronous opening and closing of the first jaw 3 and the second jaw 4. The fixing method of the first pin ensures that the first link 1 and the second link 2 will not experience axial displacement during rotation.

[0054] This embodiment provides a stable rotation center for the first connecting rod 1 and the second connecting rod 2 by providing a coaxial first hinge hole 11 and a second hinge hole 21, and fixing them with a first pin. The coaxiality of the first hinge hole 11 and the second hinge hole 21 ensures smooth and stable rotation of the first connecting rod 1 and the second connecting rod 2. The fixing method of the first pin prevents the first connecting rod 1 and the second connecting rod 2 from loosening under force. This connection structure enhances the rigidity of the device, ensures the stability of the first jaw 3 and the second jaw 4 during the clamping process, and extends the service life of the device.

[0055] In some embodiments, see Figures 1-3 , Figure 6 and Figure 7 The first connecting rod 1 has a third hinge hole 12 at its end away from the first jaw 3. The second connecting rod 2 has a fourth hinge hole 22 at its end away from the second jaw 4. The first lead screw 5 has a fifth hinge hole 51 at one end, corresponding to the third hinge hole 12 on the first connecting rod 1. The second lead screw 6 has a sixth hinge hole 61 at one end, corresponding to the fourth hinge hole 22 on the second connecting rod 2. The third hinge hole 12 and the fifth hinge hole 51 have the same diameter, and their through-hole diameters are adapted to the diameter of the second pin. The fourth hinge hole 22 and the sixth hinge hole 61 have the same diameter, and their through-hole diameters are adapted to the diameter of the third pin. The second pin passes through the third hinge hole 12 and the fifth hinge hole 51 in sequence, hinged together by the first connecting rod 1 and the first lead screw 5. The third pin passes through the fourth hinge hole 22 and the sixth hinge hole 61 in sequence, hinge the second connecting rod 2 and the second lead screw 6 together.

[0056] Specifically, during the operation of the monorail track connection alignment device, when the operator operates the ratchet mechanism to drive the first lead screw 5 and the second lead screw 6, the first connecting rod 1 can rotate around the second pin, and the second connecting rod 2 can rotate around the third pin. This hinge method can adapt to the angle changes of the first lead screw 5 and the second lead screw 6 during movement, avoiding motion interference between the first connecting rod 1 and the first lead screw 5, and between the second connecting rod 2 and the second lead screw 6, ensuring stable force transmission. When the first lead screw 5 and the second lead screw 6 produce opposite linear motion, the second pin drives the end of the first connecting rod 1 to move synchronously, and the third pin drives the end of the second connecting rod 2 to move synchronously, thereby pushing the first connecting rod 1 and the second connecting rod 2 to rotate around the cross hinge point, realizing the synchronous approach or departure of the first jaw 3 and the second jaw 4.

[0057] As can be seen from the above technical solution, this embodiment achieves flexible connection between the first connecting rod 1 and the first lead screw 5, and between the second connecting rod 2 and the second lead screw 6, by setting a third hinge hole 12 on the first connecting rod 1, a fifth hinge hole 51 on the first lead screw 5 and hinged by a second pin, setting a fourth hinge hole 22 on the second connecting rod 2, and a sixth hinge hole 61 on the second lead screw 6 and hinged by a third pin. This connection structure ensures the adaptability of the lead screw movement and the connecting rod movement, avoids structural jamming, makes the transmission smoother during operation, improves the operational reliability of the device, and also ensures the synchronization of the movement of the first jaw 3 and the second jaw 4, providing a stable structural foundation for the positioning operation of the monorail.

[0058] In some embodiments, see Figure 1 The ratchet mechanism 7 is equipped with a reversing lever 71. The reversing lever 71 is located on the outside of the housing of the ratchet mechanism 7. The reversing lever 71 is connected to the pawl inside the ratchet mechanism 7.

[0059] It should be noted that the operator changes the transmission direction of the ratchet mechanism 7 by moving the reversing lever 71. When the reversing lever 71 is in the first position, the ratchet mechanism 7 drives the first lead screw 5 and the second lead screw 6 to produce opposing linear movements. When the reversing lever 71 is in the second position, the ratchet mechanism 7 drives the first lead screw 5 and the second lead screw 6 to produce opposing linear movements. The reversing lever 71 achieves the switching of transmission direction by changing the meshing relationship between the pawl and the ratchet. When the operator needs to adjust the opening size of the first jaw 3 and the second jaw 4, they can switch the transmission direction and thus adjust the opening size by operating the reversing lever 71.

[0060] In this embodiment, a reversing lever 71 is provided on the ratchet mechanism 7, allowing the operator to select the movement direction of the first jaw 3 and the second jaw 4 according to actual needs. The structural design of the reversing lever 71 simplifies the operation process of the device and improves its ease of use. The operator can switch the transmission direction without changing the operating position, which improves the adaptability and working efficiency of the monorail rail connection positioning device.

[0061] In some embodiments, see Figure 1 The clamping surfaces of the first jaw 3 and the second jaw 4 are positioned opposite each other. The clamping surface of the first jaw 3 faces the clamping surface of the second jaw 4. The clamping surface of the second jaw 4 faces the clamping surface of the first jaw 3. The two clamping surfaces are in a parallel and directly opposite position.

[0062] It should be understood that when the monorail rail connection alignment device is working, the clamping surface of the first jaw 3 contacts one side surface of the monorail rail, and the clamping surface of the second jaw 4 contacts the other side surface of the monorail rail. The clamping surfaces of the first jaw 3 and the second jaw 4 apply forces to the monorail rail simultaneously from opposite directions, and the directions of the forces are always directly opposite each other. This relative arrangement of the clamping surfaces ensures that the force is evenly transmitted to the monorail rail. During the clamping process, the clamping surfaces of the first jaw 3 and the second jaw 4 maintain a relative positional relationship, working together to complete the clamping operation of the monorail rail.

[0063] In this embodiment, the clamping surfaces of the first jaw 3 and the second jaw 4 are arranged opposite each other, allowing both clamping surfaces to act simultaneously on the monorail track from opposite directions. This arrangement ensures a symmetrical distribution of clamping force, preventing the monorail track from tilting during clamping. The relative relationship between the clamping surfaces of the first jaw 3 and the second jaw 4 ensures the stability of the device when clamping the monorail track, providing a reliable clamping basis for the correct positioning of the monorail track. Furthermore, since the two clamping surfaces are always opposite each other, when the first lead screw 5 and the second lead screw 6 move the jaws closer or further apart, only the distance between the two jaws needs to be adjusted to accommodate monorail tracks of different widths, further expanding the applicability of the device.

[0064] In some embodiments, both the clamping surfaces of the first jaw 3 and the second jaw 4 are provided with anti-slip textures. The anti-slip textures on the clamping surface of the first jaw 3 are formed by machining. The anti-slip textures on the clamping surface of the second jaw 4 are formed by machining. The anti-slip textures consist of multiple parallel grooves.

[0065] It should be noted that when the monorail track alignment device is working, due to the structure where the clamping surfaces of the first jaw 3 and the second jaw 4 are positioned opposite each other, the anti-slip texture on the clamping surface of the first jaw 3 is in close contact with one side of the monorail track, and the anti-slip texture on the clamping surface of the second jaw 4 is in close contact with the other side of the monorail track. The anti-slip texture effectively increases the coefficient of friction between the clamping surfaces and the monorail track surface, preventing relative slippage caused by dust adhering to the track surface in the mining environment or by the offset of the clamping force application point. During clamping, the anti-slip texture stably transmits the clamping force applied by the first jaw 3 and the second jaw 4 to the monorail track, ensuring that the track does not slip out of the preset adjustment direction during alignment adjustment and always moves along the alignment path.

[0066] As can be seen from the above technical solution, this embodiment improves the friction coefficient between the clamping surfaces and the monorail track surface by setting anti-slip textures on the clamping surfaces of the first jaw 3 and the second jaw 4. The structural design of the anti-slip textures enhances the reliability of clamping and prevents slippage during clamping. This anti-slip measure ensures the stability of the monorail track during positioning, improving the working effect of the monorail track connection positioning device. The anti-slip textures allow the device to adapt to monorail tracks with different surface conditions, improving the applicability of the device.

[0067] In some embodiments, see Figure 1 The monorail track connection alignment device also includes an anti-derailment chain 8, which adopts a chain structure. The two ends of the anti-derailment chain 8 are respectively connected to the end of the first connecting rod 1 away from the first lead screw 5 and the end of the second connecting rod 2 away from the second lead screw 6. One end of the anti-derailment chain 8 is connected to the first connecting rod 1 via a connecting ring. The other end of the anti-derailment chain 8 is connected to the second connecting rod 2 via a connecting ring.

[0068] It should be noted that when the monorail track connection alignment device is in operation, the anti-derailment chain 8 remains slack. The length of the anti-derailment chain 8 is designed to ensure that the first link 1 and the second link 2 can complete their clamping motion normally. If the monorail track connection alignment device accidentally comes loose during use, the anti-derailment chain 8 can immediately pull the first link 1 and the second link 2 to prevent the device from falling from the working position. The connection point of the anti-derailment chain 8 is located at the ends of the first link 1 and the second link 2, which effectively restricts the entire range of motion of the device.

[0069] As can be seen from the above technical solution, this embodiment provides fall protection for the monorail hoist track connection alignment device by setting the anti-derailment chain 8. The anti-derailment chain 8 is connected to the ends of the first link 1 and the second link 2. This connection method can play a timely role in case the device accidentally becomes loose. The structural design of the anti-derailment chain 8 does not affect the normal use of the device and provides reliable safety assurance. In the complex working environment of underground mines, the use of the anti-derailment chain 8 effectively reduces the risk of equipment falling and personnel injury during the monorail hoist track connection alignment operation, further improving operational safety.

[0070] In some embodiments, see Figure 1 The anti-derailment chain 8 has hooks at both ends. A hanging ring is located at the end of the first connecting rod 1 furthest from the first lead screw 5. A hanging ring is located at the end of the second connecting rod 2 furthest from the second lead screw 6. The hooks are detachably connected to the hanging rings on the first connecting rod 1 and the second connecting rod 2. The hooks have a bent rod-like structure. The hanging rings are welded to the ends of the first connecting rod 1 and the second connecting rod 2.

[0071] Specifically, when the anti-derailment chain 8 needs to be installed, the operator connects the hook at one end of the anti-derailment chain 8 to the hanging ring on the first connecting rod 1. The operator then connects the hook at the other end of the anti-derailment chain 8 to the hanging ring on the second connecting rod 2. The bent structure of the hook ensures stability after connection. When the anti-derailment chain 8 needs to be disassembled, the operator simply removes the hook from the hanging ring to release the connection. During the operation of the monorail track connection positioning device, the anti-derailment chain 8 remains in the installed state through the connection between the hook and the hanging ring.

[0072] As can be seen from the above technical solution, this embodiment achieves a detachable connection of the anti-derailment chain 8 by setting hooks at both ends and hanging rings on the first connecting rod 1 and the second connecting rod 2. This connection method facilitates the installation and disassembly of the anti-derailment chain 8, and makes it convenient for the maintenance and transportation of the monorail track connection positioning device. The connection structure of the hooks and hanging rings is simple and reliable, ensuring the stability of the anti-derailment chain 8 during operation. The detachable connection design improves the flexibility of use of the monorail track connection positioning device while maintaining the safety protection function of the anti-derailment chain 8.

[0073] In some embodiments, see Figures 1-5The first connecting rod 1 has a seventh hinge hole 13 at its end away from the first lead screw 5. The second connecting rod 2 has an eighth hinge hole 23 at its end away from the second lead screw 6. The first jaw 3 has a ninth hinge hole 31. The second jaw 4 has a tenth hinge hole 41. The position of the seventh hinge hole 13 corresponds to the ninth hinge hole 31 on the first jaw 3. The position of the eighth hinge hole 23 corresponds to the tenth hinge hole 41 on the second jaw 4. The seventh hinge hole 13 and the ninth hinge hole 31 have the same hole diameter, and their through-hole diameters are also adapted to the diameter of the fourth pin. The eighth hinge hole 23 and the tenth hinge hole 41 have the same hole diameter, and their through-hole diameters are also adapted to the diameter of the fifth pin.

[0074] It should be noted that the fourth pin passes through the seventh hinge hole 13 and the ninth hinge hole 31 in sequence. The fifth pin passes through the eighth hinge hole 23 and the tenth hinge hole 41 in sequence. The four and five pins are fixed at both ends by nuts. The first connecting rod 1 is hinged to the first jaw 3 through the cooperation of the seventh hinge hole 13 and the fourth pin. The second connecting rod 2 is hinged to the second jaw 4 through the cooperation of the eighth hinge hole 23 and the fifth pin. During the operation of the monorail rail connection positioning device, when the first connecting rod 1 and the second connecting rod 2 rotate around the cross hinge point, the first jaw 3 rotates around the fourth pin through the ninth hinge hole 31, and the second jaw 4 rotates around the fifth pin through the tenth hinge hole 41. When the monorail rail experiences slight deformation of the rail head or lateral tilt due to long-term use, the first jaw 3 can still make minor adjustments to the angle around the fourth pin through the ninth hinge hole 31, and the second jaw 4 can make minor adjustments to the angle around the fifth pin through the tenth hinge hole 41. This connection method transforms the rotational motion of the first link 1 and the second link 2 into the clamping motion of the first jaw 3 and the second jaw 4, enabling the first jaw 3 and the second jaw 4 to adapt to the contour changes of the monorail during the clamping process, ensuring that the clamping surface is in full contact with the rail surface.

[0075] As can be seen from the above technical solution, this embodiment achieves flexible connection between the first connecting rod 1 and the first jaw 3, and between the second connecting rod 2 and the second jaw 4, by setting a seventh hinge hole 13 on the first connecting rod 1, a ninth hinge hole 31 on the first jaw 3 and hinged by a fourth pin, setting an eighth hinge hole 23 on the second connecting rod 2, and a tenth hinge hole 41 on the second jaw 4 and hinged by a fifth pin. The corresponding positions of the seventh hinge hole 13 and the ninth hinge hole 31, and the corresponding positions of the eighth hinge hole 23 and the tenth hinge hole 41, avoid jaw offset or hinge jamming during connection, ensuring the centering of the connection. This connection structure ensures that the first jaw 3 and the second jaw 4 can adapt to the contour of the monorail during clamping. The cooperation of the seventh hinge hole 13 and the ninth hinge hole 31, and the cooperation of the eighth hinge hole 23 and the tenth hinge hole 41, provide stable rotation fulcrums for the first jaw 3 and the second jaw 4. The fixed installation method of the fourth and fifth pins ensures that the first jaw 3 and the second jaw 4 remain stable under force. This connection method allows the first jaw 3 and the second jaw 4 to apply clamping force evenly to the monorail track, improving the working effect of the monorail track connection alignment device.

[0076] In some embodiments, see Figure 1 The first link 1 and the second link 2 are symmetrical structures. The structural dimensions of the first link 1 and the second link 2 are the same. The shapes of the first link 1 and the second link 2 are the same. The installation positions of the first link 1 and the second link 2 are symmetrically arranged with respect to the center of the device.

[0077] It should be noted that during the operation of the monorail track connection alignment device, the first link 1 and the second link 2 move synchronously in a symmetrical manner. When the ratchet mechanism 7 drives the first lead screw 5 and the second lead screw 6 to produce linear motion, the first link 1 and the second link 2 rotate symmetrically around the cross hinge point. The motion trajectory of the first link 1 and the motion trajectory of the second link 2 maintain a symmetrical relationship. The symmetrical arrangement of the first link 1 and the second link 2 ensures that the first jaw 3 and the second jaw 4 remain synchronized during movement.

[0078] As can be seen from the above technical solution, this embodiment sets the first connecting rod 1 and the second connecting rod 2 into a symmetrical structure, ensuring that the two connecting rods are consistent in size, shape, and installation position. This symmetrical structure ensures that the first connecting rod 1 and the second connecting rod 2 produce symmetrical motion characteristics during operation. The symmetrical arrangement of the first connecting rod 1 and the second connecting rod 2 allows for the synchronous transmission of forces from the first lead screw 5 and the second lead screw 6, avoiding asynchronous motion caused by structural asymmetry. The symmetrical structure of the first connecting rod 1 and the second connecting rod 2 guarantees the consistency of movement of the first jaw 3 and the second jaw 4 during the clamping process, improving the working stability of the monorail track connection alignment device. The symmetrical structural design allows the device to maintain force balance during movement, providing a reliable motion guarantee for the precise alignment of the monorail track.
