Description

Technical field:

[0001] The utility model relates to the field of rail transportation, in particular to an automatic oil brushing device for a lock hook. Background technology:

[0002] In the turnout of rail transportation, the lock plate is controlled to drive the lock hook to complete the action, and the lock hook hooks the lock frame to lock the turnout. After the lock hook and the lock frame are separated, the turnout is unlocked. This action process is achieved by the lock plate pushing and pulling the lock hook. When the turnout is repeatedly turned, there is a very large friction between the lock hook and the lock iron on the lock frame, which is easy to cause wear of the lock hook and other parts and jamming of the turnout. Therefore, it is necessary to regularly apply lubricating oil to the friction part between the lock hook and the lock iron to keep it lubricated at all times.

[0003] Taking railway transportation in rail transportation as an example, now the application of lubricating oil to the lock hook is mainly done manually. Since the turnout is a hub of rail transportation, the turnout moves frequently, and the weather changes outside are harsh, the lubricating oil applied to the lock hook will be consumed quickly. In order to ensure the normal operation of the turnout, on-site railway maintenance personnel often have to apply lubricating oil to the friction surface of the lock hook, sometimes every day, and when applying lubricating oil to the lock hook, it is also necessary to maintain the continuous operation of railway transportation. The existing method of applying lubricating oil to the lock hook not only has a huge workload but also poses a personal safety hazard, resulting in huge labor costs. Summary of the invention:

[0058] Embodiment 1:

[0059] The utility model provides a locking hook automatic oiling device, which can be applied to the field of rail transportation. Figure 1 , 2 As shown in , 3 and 4, the lock hook 1 and the locking frame 2 that can be used for the turnout may include: a placer 3 and an oil brushing part 4;

[0060] The placing device 3 has a first lower outlet 3-1 at the lower part, and is connected to the locking frame 2 through a first connection method;

[0061] Here, the shape of the first lower outlet 3 - 1 is not limited.

[0062] The first connection method may be any one or a combination of hinge connection, lock connection, mortise and tenon connection, hinge connection, groove connection, screw connection, etc., or other similar connection methods or a combination of several connection methods, or magnetic connection, welding, etc. The specific connection method is not limited here, as long as it can achieve the connection between the placement device 3 and the locking frame 2.

[0063] In this embodiment, the first connection method is illustrated by taking bolt connection as an example, but it is not a limitation to the first connection method.

[0064] The oil brushing part 4 passes through the first lower outlet 3-1 and is connected to the placing device 3 through a second connection method;

[0065] The second connection method can be any one or a combination of hinge connection, lock connection, mortise and tenon connection, hinge connection, groove connection, screw connection, etc., or other similar connection methods or a combination of several connection methods, or magnetic connection, welding, adhesion, dragging, etc. The specific connection method is not limited here, as long as it can achieve the connection between the oil brushing part 4 and the placement device 3.

[0066] Specifically, the oil brushing part can be any organizational structure that can realize the function of applying lubricating oil, such as a soft brush, a sponge-like tissue, a string, a felt, a net, a plastic foam block, etc.

[0069] Here, only the positional relationship between the oil brushing part 4 and the lock hook 1 when the turnout is locked is limited, and the positional relationship between the oil brushing part 4 and the lock hook 1 when the turnout is separated is not limited. Optionally, at this time, it is optimal that the oil brushing part 4 contacts the upper surface of the lock hook 1, because the friction between the lock hook 1 and the locking frame 2 mostly exists on the upper surface of the lock hook 1, and brushing lubricating oil on the upper surface of the lock hook 1 can achieve lubrication to the maximum extent. Of course, lubricating oil can also be applied to other parts of the lock hook 1 where friction occurs between the lock hook 1 and the locking frame 2, and the oil brushing part 4 can also contact other parts of the lock hook 1, because during the mechanical movement, the lubricating oil will be applied to other parts that were not applied at the beginning as the friction parts move.

[0070] It should be noted here that the structure and shape of the components shown in the figure in this embodiment are only illustrative examples for the convenience of explaining the present invention, and are not intended to limit the present invention. Except for the specific implementation method shown in the figure, the size and shape of the placer 3 and the oil brushing part 4 are not limited here.

[0071] The embodiment of the utility model provides an automatic oil brushing device for a lock hook, which can make frictional contact with the lock hook through the oil brushing part passing through the first lower outlet of the placing device when the switch is locked; because the oil brushing part can make frictional contact with the lock hook when the switch is locked, the automatic oil brushing of the lock hook can be achieved through the movement of the switch. The switch part where the automatic oil brushing device for the lock hook is installed does not need to be manually applied with lubricating oil to the lock hook, thereby reducing the workload, avoiding personal safety hazards, and saving labor costs.

[0072] Embodiment 2:

[0073] Based on the first embodiment, the present utility model provides a hook automatic oiling device, which can be applied to the field of rail transportation. Figure 1 , 2 , 3, 4, refer to Figure 5 , 6 , 7, and 8, a lock hook 1 and a locking frame 2 that can be used for a turnout may include: a placer 3 and an oil brushing part 4;

[0074] The placing device 3 has a first lower outlet 3-1 at the lower part, and is connected to the locking frame 2 through a first connection method;

[0075] Here, the shape of the first lower outlet 3 - 1 is not limited.

[0076] The first connection method may be any one or a combination of hinge connection, lock connection, mortise and tenon connection, hinge connection, groove connection, screw connection, etc., or other similar connection methods or a combination of several connection methods, or magnetic connection, welding, etc. The specific connection method is not limited here, as long as it can achieve the connection between the placement device 3 and the locking frame 2.

[0077] The oil brushing part 4 passes through the first lower outlet 3-1 and is connected to the placing device 3 through a second connection method;

[0078] The second connection method can be any one or a combination of hinge connection, lock connection, mortise and tenon connection, hinge connection, groove connection, screw connection, etc., or other similar connection methods or a combination of several connection methods, or magnetic connection, welding, adhesion, dragging, etc. The specific connection method is not limited here, as long as it can achieve the connection between the oil brushing part 4 and the placement device 3.

[0079] Specifically, the oil brushing part can be any organizational structure that can realize the function of applying lubricating oil, such as a soft brush, a sponge-like tissue, a string, a felt, a net, a plastic foam block, etc.

[0080] In this embodiment, the second connection mode is illustrated by taking the placement mode as an example, which is not a limitation to the second connection mode.

[0081] When the switch is locked, the oil brushing portion 4 is in frictional contact with the locking hook 1 .

[0082] Here, only the positional relationship between the oil brushing part 4 and the lock hook 1 when the turnout is locked is limited, and the positional relationship between the oil brushing part 4 and the lock hook 1 when the turnout is separated is not limited. Optionally, at this time, it is optimal that the oil brushing part 4 contacts the upper surface of the lock hook 1, because the friction between the lock hook 1 and the locking frame 2 mostly exists on the upper surface of the lock hook 1, and brushing lubricating oil on the upper surface of the lock hook 1 can achieve lubrication to the maximum extent. Of course, lubricating oil can also be applied to other parts of the lock hook 1 where friction occurs between the lock hook 1 and the locking frame 2, and the oil brushing part 4 can also contact other parts of the lock hook 1, because during the mechanical movement, the lubricating oil will be applied to other parts that were not applied at the beginning as the friction parts move.

[0083] It should be noted here that the structure and shape of the components shown in the figure in this embodiment are only illustrative examples for the convenience of explaining the present invention, and are not intended to limit the present invention. Except for the specific implementation method shown in the figure, the size and shape of the placer 3 and the oil brushing part 4 are not limited here.

[0084] Optionally, in the automatic oil brushing device for the lock hook, the oil brushing part 4 may include an oil storage part 4-1 and a brushing part 4-2;

[0085] The oil storage portion 4-1 is higher than the first lower outlet 3-1;

[0086] There is no absolute limitation on the shape of the oil storage portion, and any structure capable of storing lubricating oil meets the requirements of the oil storage portion.

[0087] The brushing portion 4-2 is connected to the oil storage portion 4-1;

[0088] The specific connection method is not limited here. The two can be fixedly connected in contact with each other, or can be movably connected so as to be sometimes separated and sometimes in contact, as long as the two can be in contact in at least one usage form of the locking hook automatic oiling device.

[0089] The brush portion 4-2 shown in this embodiment is fixedly connected to the oil storage portion 4-1.

[0090] At this time, the oil brushing part 4 passes through the first lower outlet 3-1 and is connected to the placing device 3 through a second connection method, which can be specifically:

[0091] The brushing part 4-2 of the oil brushing part 4 passes through the first lower outlet 3-1, and the brushing part 4-2 is connected to the placement device 3 through a second connection method;

[0092] When the switch is locked, the oil brushing part 4 is in frictional contact with the lock hook 1, which can be specifically:

[0093] When the switch is locked, the brush portion 4 - 2 is in frictional contact with the lock hook 1 .

[0094] The advantage of doing so is that the oil storage part can use gravity to transfer the stored lubricating oil to the brush part, ensuring that the brush part can continue to discharge oil for a long time, avoiding the lubricating oil on the brush part from being used up in a short period of time, and further reducing manual labor.

[0095] Moreover, the oil storage part 4-1 and the brush part 4-2 can use materials with different oil storage capacity and wear resistance according to their different uses, which can reduce the replacement frequency of various components without increasing costs, especially the replacement frequency of the brush part; it can also reduce costs without reducing the oil storage capacity, especially reduce the material cost of the oil storage part, thereby further reducing the maintenance labor of railway turnouts and reducing the maintenance cost of railway turnouts.

[0096] Further optionally, in the automatic oiling device for the lock hook, the oiling part 4 may be an integrated structure;

[0097] At this time, the oil storage part 4-1 and the brushing part 4-2 may be different parts of the oil brushing part 4;

[0098] The brushing portion 4 - 2 is connected to the oil storage portion 4 - 1 , and specifically, the brushing portion 4 - 2 is seamlessly connected to the oil storage portion 4 - 1 .

[0099] The advantage of doing this is that it can reduce the complexity of the overall machinery, facilitate manual replacement, and reduce the labor required for railway turnout maintenance.

[0100] Also further optionally, in the automatic oil brushing device for the lock hook, the brushing portion 4-2 may be a deformable soft body with tissue gaps;

[0101] When the brush portion 4 - 2 is in frictional contact with the lock hook 1 , the brush portion 4 - 2 is deformed;

[0102] If the tissue gap of the brushing portion 4 - 2 contains lubricating oil, the lubricating oil will overflow when it is deformed.

[0103] The advantage of this is that the collision between the brushing part and the lock hook can be reduced by deformation buffering, and the working loss of each component of the railway turnout can be reduced, thereby further reducing the maintenance labor of the railway turnout. The interstitial structure that overflows lubricating oil during deformation can better complete the function of applying lubricating oil to the lock hook 1.

[0104] A deformable soft material with tissue gaps is the best choice for the brush portion 4-2, but it is not a limitation on the brush portion. As long as the brush portion 4-2 can achieve frictional contact with the lock hook 1 when the switch is locked, the function of applying lubricating oil to the lock hook 1 can be realized. Because the brush portion 4-2 is connected to the oil storage portion 4-1 saturated with lubricating oil, the lubricating oil will inevitably infiltrate the brush portion. At this time, through the continuous friction movement of the lock hook, the lubricating oil will slowly infiltrate the lock hook.

[0105] Optionally, the automatic oil brushing device for the lock hook may further include a dust cover 5, and the upper portion of the placing device 3 has a first upper outlet 3-2;

[0106] When the dust cover 5 is connected to the placement device 3 through the third connection method, the dust cover 5 covers the first upper outlet 3-2.

[0107] The advantage of doing this is that it is convenient for manual installation, maintenance, replacement and oiling of the oil brushing part 4 connected to the preventer 3 through the first upper outlet 3-2, and the dust cover 5 can prevent dust, impurities and rainwater from falling into the oil brushing part 4, thereby extending the service life of the oil brushing part 4, reducing the maintenance frequency of the oil brushing part 4, and thus reducing the maintenance labor of railway turnouts.

[0108] The third connection method may be any one or a combination of hinge connection, lock connection, mortise and tenon connection, hinge connection, groove connection, screw connection, etc., or other similar connection methods or a combination of several connection methods, or magnetic connection, welding, adhesion, dragging, etc. The specific connection method is not limited here, as long as the dust cover 5 can be connected to the placement device 3 through the third connection method.

[0109] Optionally, the automatic oil brushing device for the lock hook may further include a front shield 6;

[0110] The front shield 6 covers the side of the oil brushing portion 4 away from the locking frame 2 .

[0111] The advantage of doing so is that the front shield 6 prevents dust, impurities and rainwater from entering the oil brushing part 4, thereby extending the service life of the oil brushing part 4, reducing the maintenance frequency of the oil brushing part 4, and thus reducing the maintenance labor of the railway turnout.

[0112] Optionally, the automatic oil brushing device for the lock hook may further include a side baffle 7;

[0113] The side baffle 7 shields the oil brushing portion 4 from a horizontal direction perpendicular to the movement direction of the lock hook 1 .

[0114] The advantage of doing so is that the side baffles 7 prevent dust, impurities and rainwater from entering the oil brushing part 4, thereby extending the service life of the oil brushing part 4, reducing the maintenance frequency of the oil brushing part 4, and thus reducing the maintenance labor of the railway turnout.

[0115] Optionally, the automatic oil brushing device for the lock hook may further include a protective cover;

[0116] The protective cover has a first mounting hole and is connected to the locking frame through a fourth connection method;

[0117] The fourth connection method may be any one or a combination of hinge connection, lock connection, mortise and tenon connection, hinge connection, groove connection, screw connection, etc., or other similar connection methods or a combination of several connection methods, or magnetic connection, welding, adhesion, dragging, etc. The specific connection method is not limited here, as long as the protective cover can be connected to the locking frame through the fourth connection method.

[0118] When the automatic oil brushing device for the lock hook is installed, the placer passes through the first installation hole.

[0119] The advantage of doing this is that the protective cover can prevent dust, impurities and rainwater from entering the oil brushing part and the friction area between the locking hook and the locking frame, thereby extending the service life of the oil brushing part, reducing the maintenance frequency of the oil brushing part, reducing the deterioration and consumption of the lubricating oil between the locking hook and the locking frame, and then reducing the consumption of lubricating oil, reducing the frequency of oiling, and thus reducing the maintenance labor of railway turnouts.

[0120] Optionally, the automatic oil brushing device for the lock hook may further include a fixing frame 8;

[0121] The fixing frame 8 is fixed to the locking frame 2;

[0122] At this time, the lower part of the placing device 3 has a first lower outlet 3-1, and is connected to the locking frame 2 through a first connection method, which can be specifically:

[0123] The placing device 3 has a first lower outlet 3-1 at its lower portion, and is connected to the fixing frame 8 fixed to the locking frame 2 through a first connection method.

[0124] The advantage of doing this is that when installing and repairing the parts of the placer 3 or the automatic oil brushing device for the lock hook except the fixing frame 8, it is possible to avoid disassembling the connecting structure on the locking frame, not touching the backbone components of the turnout movement, and not affecting the normal operation of the railway. While reducing the manual risk, it can also reduce the labor for railway turnout maintenance.

[0125] Further optionally, in the automatic oil brushing device for the lock hook, the fixing frame 8 may also include a positioning platform 8-1;

[0126] At this time, the lower part of the placing device 3 has a first lower outlet 3-1, and is connected to the fixing frame 8 fixed to the locking frame 2 through a first connection method, which can be specifically:

[0127] The placing device 3 has a first lower outlet 3-1 at its lower portion, and is connected to the positioning platform 8-1 of the fixing frame 8 fixed to the locking frame 2 through a first connection method.

[0128] The advantage of doing so is that the positioning platform 8-1 can prevent the components such as the placer 3 from loosening or falling during use, thereby avoiding the adverse effects on the operation of the railway turnout when the automatic oil brushing device for the lock hook fails, thereby ensuring the safe operation of the railway turnout.

[0129] The embodiment of the utility model shows the first connection mode by means of squeezing and friction fixing of the front and rear blocking sheets, but it is not a limitation to the first connection mode.

[0130] Also further optionally, the automatic oil brushing device for the lock hook may further include a protective cover;

[0131] The protective cover has a first mounting hole and is fixed to the fixing frame by a fifth connection method;

[0132] The fifth connection method may be any one or a combination of hinge connection, lock connection, mortise and tenon connection, hinge connection, groove connection, screw connection, etc., or other similar connection methods or a combination of several connection methods, or magnetic connection, welding, adhesion, dragging, etc. The specific connection method is not limited here, as long as the protective cover can be connected to the fixing frame through the fifth connection method.

[0133] When the automatic oil brushing device for the lock hook is installed, the placer passes through the first installation hole.

[0134] Further optionally, in the automatic oil brushing device for the lock hook, the fixing frame may further include a positioning platform;

[0135] The protective cover has a first mounting hole and is fixed to the fixing frame by a fifth connection method, which may be:

[0136] The protective cover has a first mounting hole and is fixed to the positioning platform on the fixing frame through a fifth connection method.

[0137] Optionally, in the automatic oil brushing device for the lock hook, the first upper surface of the oil brushing portion 4 has a depression lower than the edge of its upper surface.

[0138] The advantage of doing so is that when the lubricating oil is added to the oil brushing part, overflow caused by the lubricating oil being added too quickly can be prevented.

[0139] It should be noted here that the structure and shape of the components shown in the figure in this embodiment are only illustrative examples for the convenience of explaining the present invention, and are not limitations on the present invention. Except for the specific implementation method shown in the figure, all other implementation methods corresponding to the embodiments of the present invention may be implemented if the connection structure remains unchanged.

[0140] The embodiment of the utility model provides an automatic oil brushing device for a lock hook. When the switch is locked, the oil brushing part passing through the first lower outlet of the placement device can make frictional contact with the lock hook; because when the switch is locked, the oil brushing part can make frictional contact with the lock hook, so the automatic oil brushing of the lock hook can be achieved through the movement of the switch. The switch part where the automatic oil brushing device for the lock hook is installed does not need to manually apply lubricating oil to the lock hook, thereby reducing the workload, avoiding personal safety hazards, and saving turnout maintenance costs such as labor costs.
