DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0043] Embodiment 1: Specific implementation to solve the problems that the existing crown block track lubricating graphite cannot be automatically added and the existing crown block track lubricating graphite will cause the friction with the track to decrease and thus the lubricating effect to decrease after being consumed by wear due to gravity.

[0044] The utility model provides a kind of headgear rail lubrication graphite adding device, for the lubrication of headgear running system, headgear running system includes rail 2 and headgear running mechanism 1, headgear running mechanism 1 moves on rail 2 by running wheel 11, the side of headgear running mechanism 1 is provided with graphite lubrication sleeve 3, graphite lubrication sleeve 3 is arranged above rail 2, the lower end of graphite lubrication sleeve 3 points to rail 2, graphite lubrication sleeve 3 is used to place graphite block 5, graphite block 5 can be contacted with the surface of rail 2 and rub under the action of gravity;One side of graphite lubrication sleeve 3 is connected with graphite block adding box 4, one side of graphite block adding box 4 is communicated with one side of graphite lubrication sleeve 3, graphite block adding box 4 is used to place spare graphite block 5 and add graphite block 5 in graphite lubrication sleeve 3, push plate 42 is arranged in graphite block adding box 4, one side of push plate 42 close to graphite lubrication sleeve 3 is used to place vertically arranged graphite block 5, and the other side is provided with thrust mechanism, when graphite block 5 in graphite lubrication sleeve 3 is consumed to certain length (this length is b), spare graphite block 5 can be pushed into graphite lubrication sleeve 3.

[0045] Wherein: when graphite block 5 in graphite lubrication sleeve 3 is consumed to certain length, spare graphite block 5 can be pushed into graphite lubrication sleeve 3, spare graphite block 5 is pressed above graphite block 5 being used before being contacted with rail 2, as Figure 6 、 Figure 7 , increase the friction force of graphite block 5 being used and rail 2.

[0046] Thrust mechanism can be hydraulic push rod, electric telescopic rod. It can also use elastic thrust mechanism, such as spring A43, spring A43 is arranged on the side of push plate 42 away from graphite lubrication sleeve 3, and spring A43 can push push plate 42 to graphite lubrication sleeve 3.

[0047] Open 41 is arranged on the upper of graphite block adding box 4.

[0048] Embodiment 2: the specific implementation of the technical problem that the friction force between the inner wall of graphite lubrication sleeve and graphite block is too large in the adding mode of push plate and spare box, especially when using elastic thrust mechanism, spring gives graphite block continuous thrust

[0049] On the basis of embodiment 1, pulley block 31 is arranged on the side of the inner wall of graphite lubrication sleeve 3 away from graphite block adding box 4, and pulley block 31 is used to reduce the resistance of graphite block 5 descending.

[0050] Embodiment 3: the specific implementation of the technical problem that the addition of spare graphite block lacks buffering in the adding mode of push plate and spare box, especially when using elastic thrust mechanism and graphite block being used reaches certain length, spare graphite block can be directly pushed to the inner wall of graphite lubrication sleeve and impact

[0051] In the embodiment 1, the left side of the upper end and the right side of the lower end of the graphite block 5 are respectively provided with the inclined surface A51 and the inclined surface B52, as shown in Figure 3 .

[0052] The slope of the inclined surface A51 is the same as that of the inclined surface B52, and the inclined surface A51 and the inclined surface B52 are also center-symmetrical.

[0053] As shown in Figure 4 , in order to ensure that the standby graphite block 5 can be supported on the graphite block 5 in use, the width of the graphite block 5 is a, and the length of the projection of the inclined surface A51 and the inclined surface B52 in the vertical direction is less than one-half a. If the width of the graphite block 5 is a, and the length of the projection of the inclined surface A51 and the inclined surface B52 in the vertical direction is greater than one-half a, then the lower end of the standby graphite block 5 cannot be supported on the upper end of the graphite block 5 in use.

[0054] When the graphite block 5 in use reaches a certain length (the length is c, and c > b), the inclined surface B52 at the lower end of the standby graphite block 5 will gradually fit the inclined surface A51 at the upper end of the graphite block 5 in use as the length of the graphite block 5 in use continues to shorten, and the graphite block 5 in use will be gradually supported by the standby graphite block 5. Figure 5 After the adoption of this scheme, the standby graphite block 5 is close to the inner wall of the graphite lubricating sleeve 3 before it is completely added to the graphite lubricating sleeve 3, and the possibility of damage of the standby graphite block 5 by impact can be reduced to a certain extent.

[0055] In addition, in the process of fitting the inclined surface, the standby graphite block 5 can also provide a downward force (a component of the thrust) for the graphite block 5 in use, and the downward force for the graphite block 5 in use is provided in advance.

[0056] Embodiment 4: A specific implementation method for solving the lack of support in the adding mode of the standby graphite block by adopting the push plate and the standby box

[0057] As shown in Figure 5 , as the length of the graphite block 5 in use gradually shortens, the support at the right side of the upper end of the standby graphite block 5 gradually lacks, and thus the upper end of the standby graphite block 5 is prone to tilting after the length of the graphite block 5 in use is shortened to a certain extent, and thus the embodiment is proposed.

[0058] The difference from the embodiment 1 is that the support wheel 32 is included, the graphite lubricating sleeve 3 is provided with a sliding hole 33, the wheel shaft of the support wheel 32 is arranged on the sliding hole 33 and can slide relative to the sliding hole 33, and the support wheel 32 is used to support the subsequent graphite block 5 after the graphite block 5 is added to the graphite lubricating sleeve 3 and lowered.

[0059] Wherein: graphite block adds the box 4 to set up spring support 44, spring support 44's height corresponds with the height of slide hole 33, spring support 44 is set up with spring B 34 between the wheel axle of support wheel 32, spring B 34 is not forced when support wheel 32 is located in slide hole 33 close to graphite block adds the box 4 one end.

[0060] Because the support wheel 32 in this embodiment 1 acts on the right side of the upper end of the spare graphite block 5, the spring B 34 does not need to select a spring with too large a stiffness coefficient, and can keep the upper end of the spare graphite block 5 from falling over.

[0061] This embodiment can be implemented independently, or can be implemented with embodiment 2, for example, selecting one or more pulleys in the pulley block 31 as the support wheel 32.

[0062] Embodiment 5: Conveniently understand the number of graphite blocks 5 in the graphite block adding box 4

[0063] As Figure 15 The difference from embodiment 1 is that the push plate 42 is connected with an indicating rod A 45, the indicating rod A 45 can be selected to extend above the opening 41, the indicating rod A 45 is provided with an indicating rod B 35 near one side of the graphite lubricating sleeve 3, the indicating rod B 35 can be provided at the upper end of the graphite lubricating sleeve 3, and the distance between the indicating rod A 45 and the indicating rod B 35 can be used to determine the number of graphite blocks 5 in the graphite block adding box 4.

[0064] It should be noted that in the description of the invention, the terms "upper", "lower", "left", "right", "front", "back" and the like indicate the orientation or positional relationship of the structure of the invention shown in the drawings, and are only for the convenience of describing the invention simply, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the invention.

[0065] For "first" and "second" in this technical solution, it is only a call for distinction between the same or similar structures, or corresponding structures with similar functions, and is not a ranking of the importance of these structures, nor does it have the meaning of ordering, comparing size, or other meanings.

[0066] In addition, unless otherwise explicitly specified and limited, the terms "mounting", "connection" should be understood broadly, for example, the connection can be fixed connection, or detachable connection, or integrally connected; can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through an intermediate medium; can be the communication inside two structures. For those skilled in the art, the specific meaning of the above terms in the invention can be understood according to the overall idea of the invention and the specific circumstances of the context of the present solution.
