Description

[0002] With the development of technology and the progress of society, more and more mines are choosing to build unmanned underground locomotive systems. Underground rail transport systems are developing towards unmanned operation, intelligence, safety, and standardization. The mine locomotive pin-removing device is a crucial component in achieving unmanned operation of underground rail transport systems. During underground rail transport, it is frequently necessary to remove and re-install the connecting pins of the locomotive to meet different production needs.

[0003] In traditional underground rail transport systems, when a dual-motor locomotive train carrying ore cars arrives at the mine entrance, the locomotive needs to push the cars into the cage and then lift them to the surface. At this point, underground workers need to remove the connecting pin between the front locomotive and the cars, disconnecting the connection, and then use the rear locomotive to push the cars into the cage in groups.

[0004] Among these challenges, when underground workers remove and reinsert the connecting pins, they are at risk of injury from vehicle movement because they need to be positioned between the locomotive and the carriage. Additionally, the connecting pins are heavy, making it difficult for workers to remove them when the locomotive and carriage are under pressure. Summary of the Invention

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this application provides a pin removal device 100. The pin removal device 100 includes a mounting assembly 110, a pin removal assembly 130, and an adjustment assembly 120.

[0026] The mounting assembly 110 is used to mount the pin removal device 100 onto the locomotive 101. The pin removal assembly 130 is disposed on the side of the mounting assembly 110 opposite to the locomotive 101.

[0027] The pin removal assembly 130 includes an adsorption member 133 and a driving member 132. The adsorption member 133 is connected to the driving member 132. The adsorption member 133 is used to adsorb the connecting pin 103 connecting the electric locomotive 101 and the carriage 102. The driving member 132 is used to drive the adsorption member 133 to move closer to or away from the connecting pin 103 to complete the pin removal or pin insertion action.

[0028] Additionally, the adjustment component 120 is disposed between the mounting component 110 and the pin removal component 130, the adjustment component 120 is connected to the mounting component 110, and one end of the adjustment component 120 away from the mounting component 110 is connected to the pin removal component 130.

[0029] In this embodiment, the position of the pin removal component 130 relative to the mounting component 110 is adjusted by the adjustment component 120, and the pin removal component 130 is aligned with the connecting pin 103.

[0030] In related technologies, the locomotive needs to push the cars into the cage and then lift them to the surface. Underground workers then disconnect the locomotive from the cars by removing the connecting pin, allowing the rear locomotive to push the cars into the cage in groups. However, removing and reinstalling the connecting pin poses a risk of injury from vehicle movement, as workers are positioned between the locomotive and the cars. Furthermore, the heavy connecting pin makes it difficult to remove when the locomotive and cars are compressed, resulting in low efficiency and safety.

[0031] In this embodiment, the pin removal device 100 includes an installation component 110, a pin removal component 130, and an adjustment component 120. In this embodiment, the connecting pin 103 is adsorbed by the adsorption component 133, and the adsorption component 133 is driven by the driving component 132 to realize automatic pin removal and pin insertion. This reduces the number of underground workers and allows workers to complete tasks such as changing the machine head independently without having to accompany the machine, thereby improving the safety and efficiency of the operation.

[0032] Optionally, such as Figure 2 and Figure 4 As shown, the mounting assembly 110 includes a mounting plate 111. The mounting plate 111 is mounted on the electric locomotive 101. Specifically, the mounting plate 111 is mounted at the rear of the electric locomotive 101, that is, at the end of the electric locomotive 101 near the connecting carriage 102. Optionally, the mounting plate 111 is mounted on the electric locomotive 101, for example, by welding.

[0033] The adjustment component 120 is mounted on the side of the mounting plate 111 opposite to the locomotive 101. The mounting plate 111 is used to mount the pin removal device 100 on the side of the locomotive 101 near the carriage 102. Optionally, the adjustment component 120 and the mounting plate 111 are movably connected.

[0034] Optionally, such as Figure 2 and Figure 4 As shown, the adjustment assembly 120 includes a first adjustment member 121 and a second adjustment member 122.

[0035] Specifically, the first adjusting member 121 is disposed on the side of the adjusting assembly 120 near the mounting assembly 110. The first adjusting member 121 is connected to the mounting assembly 110 and is movable relative to the mounting assembly 110.

[0036] Specifically, the first adjusting member 121 moves on the side of the mounting plate 111 away from the locomotive 101, thereby driving the pin removal assembly 130 to move along the side of the mounting assembly 110 close to the adjusting member 120, so that the pin removal assembly 130 can be adjusted in the lateral and longitudinal directions along the mounting plate 111 to align the pin removal assembly 130 with the connecting pin 103 between the locomotive 101 and the carriage 102.

[0037] Optionally, such as Figure 11 As shown, the horizontal direction of the mounting plate 111 is, for example, the horizontal direction after the pin removal device 100 is installed on the locomotive 101, and the vertical direction of the mounting plate 111 is, for example, the vertical direction after the pin removal device 100 is installed on the locomotive 101.

[0038] Additionally, the second adjustment member 122 is disposed at the end of the first adjustment member 121 away from the mounting assembly 110, and the second adjustment member 122 is located between the first adjustment member 121 and the pin removal assembly 130.

[0039] The second adjusting member 122 is fixedly connected to the first adjusting member 121, for example, by a screw connection. The side of the second adjusting member 122 facing away from the first adjusting member 121 is connected to the pin-removing assembly 130. In this embodiment, the second adjusting member 122 adjusts the distance between the pin-removing assembly 130 and the mounting assembly 110, thereby further ensuring that the pin-removing assembly 130 is aligned with the connecting pin 103.

[0040] Optionally, such as Figure 5 and Figure 6 As shown, the first adjusting member 121 includes a magnet 1211. The magnet 1211 is attracted to the side of the mounting assembly 110 opposite to the locomotive 101. The magnet 1211 is movable on the side of the mounting plate 111 near the adjusting assembly 120. The magnet 1211 is used to mount the adjusting assembly 120 onto the mounting assembly 110 and to adjust the position of the pin-removing assembly 130 relative to the mounting assembly 110.

[0041] Optionally, such as Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the magnet 1211 is an adsorption magnet 1211, and the magnet 1211 has a magnetic switch 1212. When the magnetic switch 1212 is in the open state, the magnet 1211 will be adsorbed onto the mounting plate 111, thereby fixing the magnet 1211 onto the mounting plate 111. When the magnetic switch 1212 is in the closed state, the magnet 1211 will detach from the mounting plate 111, allowing the magnet 1211 to move on the mounting plate 111 and adjust its position. This allows for position adjustment of the pin removal assembly 130 within the area of ​​the mounting plate 111 near the adjustment assembly 120, aligning the pin removal assembly 130 with the connecting pin 103, facilitating the smooth completion of subsequent pin removal and insertion actions.

[0042] In other embodiments, the first adjusting member 121 may also be a movable block, which is movably engaged with the mounting plate 111 via a universal joint. After the movable block moves to the target position on the mounting plate 111, it is fixed to the mounting plate 111 by its self-locking function.

[0043] Optionally, such as Figure 4 , Figure 7 and Figure 8 As shown, the second adjusting member 122 includes a connecting frame 1221. The connecting frame 1221 has a first receiving cavity 1221a. The end of the connecting frame 1221 near the first adjusting member 121 is fixedly connected to the first adjusting member 121, for example, by a screw connection or a bolt connection.

[0044] It should be noted that the pin removal component 130 extends from the end of the connecting frame 1221 away from the first adjusting member 121 into the first receiving cavity 1221a, and the connecting frame 1221 and the pin removal component 130 are telescopically connected.

[0045] Optionally, such as Figure 8 As shown, the second adjusting member 122 further includes a first set screw and a second set screw, and the connecting frame 1221 has a first connecting hole 1221b and a second connecting hole 1221c.

[0046] Specifically, the first connecting hole 1221b is disposed on the side of the connecting frame 1221 adjacent to the mounting assembly 110. The axis of the first connecting hole 1221b is parallel to the mounting plate 111, and the first set screw passes through the first connecting hole 1221b and is threadedly connected to the connecting frame 1221.

[0047] It should be noted that the first set screw is located at one end in the first receiving cavity 1221a and abuts against the pin removal assembly 130. In this embodiment, the first set screw is used to fix the pin removal assembly 130 and adjust the distance between the pin removal assembly 130 and the mounting assembly 110.

[0048] Optionally, such as Figure 11 As shown, after the pin-removing device 100 is installed on the locomotive 101, the axial direction of the first connecting hole 1221b and the first set screw is consistent with the transverse direction of the mounting plate 111. It should be noted that the first set screw in this embodiment can also allow the pin-removing assembly 130 to be moved and finely adjusted along the axial direction of the first set screw, thereby realizing the adjustment of the pin-removing assembly 130 in the horizontal direction and further improving the accuracy of the alignment between the pin-removing assembly 130 and the connecting pin 103.

[0049] Optionally, there may be two first connecting holes 1221b, with the two first connecting holes 1221b respectively disposed opposite to each other on both sides of the connecting frame 1221. In this embodiment, the first set screws are disposed one-to-one with the first connecting holes 1221b, so the number of first set screws is also two, with the two first set screws respectively passing through the first connecting holes 1221b. In this embodiment, the position of the pin removal assembly 130 relative to the mounting assembly 110 is adjusted by the two first set screws, which improves the efficiency of aligning the pin removal assembly 130 with the connecting pin 103 and improves its working efficiency.

[0050] It should be noted that this embodiment does not limit the number of the first connecting hole 1221b and the first set screw. The specific number of the first connecting hole 1221b and the first set screw can be designed according to the actual production situation.

[0051] Optionally, the second connecting hole 1221c is disposed on the side of the connecting frame 1221 adjacent to the mounting assembly 110, the axis of the second connecting hole 1221c is parallel to the mounting plate 111, and the axis of the second connecting hole 1221c is perpendicular to the axis of the first connecting hole 1221b, and the axis of the second connecting hole 1221c is parallel to the pin removal direction of the pin removal assembly 130.

[0052] The second set screw passes through the second connecting hole 1221c, and one end of the second set screw located in the first receiving cavity 1221a abuts against the pin removal assembly 130. The second set screw and the first set screw together fix the pin removal assembly 130 and adjust the distance between the pin removal assembly 130 and the connecting pin 103, thereby aligning the pin removal assembly 130 and the connecting pin 103 and improving their working efficiency.

[0053] Optionally, such as Figure 11As shown, after the pin-removing device 100 is installed on the locomotive 101, the axial direction of the second connecting hole 1221c and the second set screw is consistent with the longitudinal direction of the mounting plate 111. It should be noted that the second set screw in this embodiment can also allow the pin-removing assembly 130 to be moved and finely adjusted along the axial direction of the second set screw, thereby realizing the adjustment of the pin-removing assembly 130 in the vertical direction and further improving the accuracy of the alignment between the pin-removing assembly 130 and the connecting pin 103.

[0054] Optionally, there may be two second connecting holes 1221c, with the two second connecting holes 1221c respectively disposed opposite to each other on both sides of the connecting frame 1221. In this embodiment, the second set screws are disposed one-to-one with the second connecting holes 1221c, so the number of second set screws is also two, with the two second set screws respectively passing through the second connecting holes 1221c. In this embodiment, the position of the pin removal assembly 130 relative to the mounting assembly 110 is adjusted by the two second set screws, which improves the efficiency of aligning the pin removal assembly 130 with the connecting pin 103 and improves its working efficiency.

[0055] It should be noted that this embodiment does not limit the number of the second connecting hole 1221c and the second set screw. The specific number of the second connecting hole 1221c and the second set screw can be designed according to the actual production situation.

[0056] Optionally, multiple nuts are welded to the outer surface of the connecting frame, each nut corresponding to a first connecting hole 1221b or a second connecting hole 1221c. In this embodiment, the first set screw is sequentially passed through the nut near the first connecting hole 1221b and the first connecting hole 1221b, and the second set screw is sequentially passed through the nut near the second connecting hole 1221c and the second connecting hole 1221c.

[0057] In this embodiment, multiple nuts are welded to the outer surface of the connecting frame to further enhance the stability of the connection between the first and second set screws and the connecting frame 1221.

[0058] Optionally, the size of each of the plurality of nuts is, for example, M20.

[0059] In other embodiments, a hydraulic column can be used instead of the first and second set screws, which are inserted into the first connecting hole 1221b and the second connecting hole 1221c. The hydraulic column can enhance the connection between the pin-removing assembly 130 and the adjusting assembly 120.

[0060] Optionally, such as Figure 7 , Figure 9 and Figure 10As shown, the pin-removing assembly 130 also includes a housing 131, which is disposed on the side of the adjusting assembly 120 opposite to the mounting assembly 110. A connecting block is provided on the side of the housing 131 near the second adjusting member 122. The housing 131 passes through this connecting block in the second receiving cavity and is abutted against the connecting block by a first setter screw and a second setter screw, thereby fixing it to the second adjusting member 122.

[0061] In this embodiment, the distance between the pin removal assembly 130 and the mounting assembly 110 is adjusted by controlling the length of the connecting block in the second receiving cavity, thereby achieving a retractable connection between the outer shell 131 and the adjustment assembly 120.

[0062] In addition, the outer shell 131 has a second receiving cavity, and the driving member 132 is disposed in the second receiving cavity. The driving member 132 is fixedly connected to the outer shell 131, and the fixed connection method is, for example, a bolt connection.

[0063] The adsorption element 133 is disposed at one end of the output shaft of the drive element 132, that is, at the end of the housing 131 near the connecting pin 103, and the adsorption element 133 is connected to the output shaft of the drive element 132.

[0064] Optionally, the drive unit 132 includes an electric push rod disposed in the second receiving cavity, and the electric push rod is bolted to the end of the housing 131 away from the adsorption member 133.

[0065] Specifically, the end of the electric push rod near the adsorption member 133 is connected to the adsorption member 133 by a thread. In this embodiment, the electric push rod drives the adsorption member 133 to move closer to or away from the connecting pin 103 so that the adsorption member 133 can remove or insert the connecting pin 103.

[0066] Optionally, the adsorption element 133 includes an electromagnet, the side of which is fixedly connected to the electric push rod near the electric push rod. Optionally, the side of the electromagnet near the electric push rod has threads, and the electromagnet is connected to the electric push rod via the threads.

[0067] The side of the electromagnet facing away from the electric push rod is used to attract the connecting pin 103 to complete the pin removal or insertion action.

[0068] Optionally, the pin removal device 100 further includes a control component, which is electrically connected to the pin removal component 130. That is, in this embodiment, the control component is electrically connected to the electric push rod and the electromagnet.

[0069] The control component is used to control the drive member 132 to move the adsorption member 133 closer to or away from the connecting pin 103, and to control the adsorption member 133 to adsorb or release the connecting pin 103, so as to complete the pin removal or pin insertion action.

[0070] Optionally, the control component may be, for example, a dedicated vehicle-mounted control terminal for the electric locomotive 101 unmanned driving system, which includes a PLC (Programmable Logic Controller) and a WIFI (Wireless Fidelity) module.

[0071] Specifically, by operating the control component, the electric push rod in this embodiment is extended, causing the electromagnet to approach the connecting pin 103. The electromagnet then covers one end of the connecting pin 103 and attracts it. Further, by operating the control component, the electric push rod in this embodiment is retracted, causing the electromagnet with the attracted connecting pin 103 to move away from the initial installation position of the connecting pin 103, thereby completing the pin removal action of the pin removal system.

[0072] Furthermore, by operating the control component, the electric push rod in this embodiment extends, causing the electromagnet with the connecting pin 103 attached to it to approach the installation position of the connecting pin 103. The electromagnet then inserts the connecting pin 103 into the connection between the locomotive 101 and the carriage 102, i.e., the installation position of the connecting pin 103. Further, by operating the control component, the electromagnet releases the connecting pin 103, causing the electric push rod in this embodiment to retract, moving the electromagnet away from the installed connecting pin 103, thereby completing the pin insertion action of the pin removal system.

[0073] This embodiment controls the electric push rod and electromagnet through the control components, so that the pin removal device 100 can remove or insert the connecting pin 103 between the locomotive 101 and the carriage 102. In the PLC program of the on-board control terminal, the device can determine whether the connecting pin 103 has been removed and inserted by monitoring the extension and retraction of the electric push rod. This reduces the number of workers in the well and eliminates the risk of workers working at the tail of the locomotive 101.

[0074] Meanwhile, the pin removal device 100 in this embodiment has a relatively stable structure. The radial load limit of the electric push rod and the electromagnet attraction force are much greater than the weight of the connecting pin 103 body. Therefore, the pin removal device 100 in this embodiment can achieve the design goal. This embodiment provides a pin removal device 100 and a pin removal system, which has the pin removal device 100 described in any of the above embodiments, and therefore has all the beneficial effects of the pin removal device 100, which will not be described in detail here.
