Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Embodiment one:
referring to fig. 1, the present embodiment provides a vacuum pipeline transportation system covered with an ultra-smooth lubrication layer, which includes a vacuum pipeline body 1 and a vehicle body 2 in the vacuum pipeline body, wherein a sliding rail 12 is laid in the vacuum pipeline body 1, and a sliding block 21 for sliding connection with the sliding rail 12 is disposed at the bottom of the vehicle body 2.
Referring to fig. 1 and 2, a sliding rail 12 is disposed in the vacuum pipe body 1, a roadbed 11 is disposed on the vacuum pipe body 1, and the sliding rail 12 is disposed on the roadbed 11. The surface of the sliding rail 12 is provided with a first lubricating layer 13, and the first lubricating layer 13 is detachably connected with the sliding rail 12.
Specifically, the first lubricating layer 13 includes a substrate 131 and a molybdenum disulfide film 132 disposed on a surface of the substrate 131. The base 131 serves as a carrier to which the molybdenum disulfide film 132 is attached, so that the strength of the sliding rail is enhanced, and the upper surface of the base 131 is concave, so that the shape of a sliding block of a vehicle can be matched with the concave. It should be noted that the molybdenum disulfide film 132 is adhered, brushed, sprayed or sputtered on the substrate 131. Through experiments, the sliding friction coefficient of molybdenum disulfide in vacuum can be smaller to reach the ultra-sliding degree, namely smaller than 0.01 and reaching 0.0016. Under the same conditions, the friction coefficient of the bonded solid lubricating film containing molybdenum disulfide in vacuum is about 1/3 of that in the atmosphere, and the wear-resistant service life is several times or even tens times higher than that in the atmosphere. Therefore, the molybdenum disulfide bonded solid lubricating film is the first choice material for vacuum mechanical lubrication.
Since the vehicle is operated in a sliding mode, the molybdenum dioxide film 132 on the surface of the slide rail 12 is easily worn after long-time operation, and thus the molybdenum dioxide film 132 needs to be removed and replaced.

referring to fig. 3 and fig. 4, the upper surface of the sliding rail 12 is provided with a plurality of clamping grooves, and the first lubrication layer 13 is specifically provided with a clamping portion 133 at the bottom of the base 131; the clamping groove comprises a sliding groove 121 into which the clamping part 133 slides and a first accommodating groove 122 for accommodating the clamping part 133, and the sliding groove 121 is communicated with the first accommodating groove 122 and is L-shaped as a whole. The size of the opening of the sliding-in groove 121 is enough for the clamping part 133 to penetrate; it should be noted that, the joint portion 133 is provided with an inclined plane at the joint portion with the first accommodating groove 122, and as the joint portion 133 stretches into the first accommodating groove, the two inclined planes are close to each other, so that the joint portion 133 is tightly adhered to the first accommodating groove 122, and the first lubricating layer 13 is more stable in installation.
At least one clamping groove is internally provided with a locking mechanism for locking the clamping part and a tripping mechanism for enabling the clamping part to be separated from the clamping groove.
Referring to fig. 5, the locking mechanism includes an elastic supporting bar 123 disposed along a length direction of the first accommodating groove 122, a first end of the elastic supporting bar 123 is fixedly connected with a sidewall of the first accommodating groove 122, a second end extends toward the sliding groove 121, and a second end of the elastic supporting bar 123 is provided with a limit hook portion 124; when the clamping portion 133 is located in the first accommodating groove 122, the limiting hook portion 124 clamps the clamping portion 133, and limits the movement of the clamping portion 133, so as to lock the first lubricating layer 13.
The trip mechanism comprises a stud 125 fixedly connected with the second end of the elastic support bar 123, a through hole 126 for the stud 125 to pass through is formed in the position of the slide rail 12 opposite to the limit hook 124, and a nut 127 is arranged at the tail end of the stud 125. In a natural state, the elastic supporting bar 123 is in a horizontal state, the limiting hook portion 124 clamps the clamping portion 133, when the first lubricating layer 13 needs to be replaced, the clamping portion 133 needs to be tripped from the limiting hook portion 124, and the second end of the elastic supporting bar 123 moves along a direction away from the clamping portion 133 by rotating the nut 127 until the state shown in fig. 6, the clamping portion 133 can freely move in the first accommodating groove 122, and a tripping effect is achieved. After the first lubrication layer is replaced, the nut 127 is reversed again to reset the elastic support bar 123, so that locking can be realized again.
In order to accommodate the bolt 127 and the end of the stud 126, the slide rail 12 is provided with a second accommodating groove 128 for accommodating the end of the stud and the nut, and the second accommodating groove 128 penetrates at least one side of the slide rail 12, so that a finger or a tool (such as a wrench) of a constructor can extend into the slide rail to rotate the nut.
Referring to fig. 1 and 7, the vehicle comprises a slider 21 disposed at the bottom of a vehicle body 2, a second lubrication layer 23 disposed on the surface of the slider 21, and the second lubrication layer 23 and the slider 21 are detachably connected. The second lubricating layer 23 includes a substrate 231 and a molybdenum disulfide film 232 disposed on the surface of the substrate. As shown in fig. 9, the detachable connection manner of the second lubrication layer 23 and the slider 21 in the present embodiment is the same as the detachable connection manner of the first lubrication layer and the sliding rail in the first embodiment, and will not be described herein. It should be noted that at least one of the first lubrication layer 13 on the sliding rail 12 and the second lubrication layer 23 on the sliding block 21 may exist, or both may exist.
Embodiment two:
