If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0047] Please refer to Figure 1 and Figure 3 , an escalator 200 is provided in an embodiment of the present application. The escalator 200 includes a truss (not shown in the figure), a step chain 20, a chain guide rail 21, an inclined part 1 rail 23, an inclined part 2 rail 24, a guide rail support plate 28 and an oil blocking device 100.

[0048] Among them, the truss spans between the upper floor and the lower floor of the building and is connected to the upper floor and the lower floor of the building respectively through its two ends in the length direction. The truss is used to support the structures of other parts of the escalator 200. The truss can be divided into an upper part and a lower part that extend horizontally and are spaced apart from each other along the direction of gravity as a whole, and an intermediate part that is connected between the upper part and the lower part and is inclined.

[0049] The step chain 20 is fitted inside the truss. Correspondingly, the step chain 20 can also be divided into an upper part, a lower part and an inclined part located between the upper part and the lower part. In addition, there is an arc transition between the upper part and the inclined part of the step chain 20 to form a first R part, and there is an arc transition between the lower part and the inclined part of the step chain 20 to form a second R part.

[0050] The chain guide rail 21 is fitted below the upper part of the step chain 20, the inclined part 1 rail 23 and the inclined part 2 rail 24 are fitted below the inclined part of the step chain 20, and the guide rail support plate 28 is fitted inside the truss and is used to support the step chain 20.

[0051] Please refer to Figures 1 to 5 , the oil blocking device 100 is arranged inside the truss and is used to block the lubricating oil drops on the step chain 20 from falling onto the guide rail support plate 28 and the cross beam 27.

[0052] Specifically, please refer to Figure 2 , Figure 4 and Figure 5 , the oil blocking device 100 includes an oil blocking assembly 10, and the oil blocking assembly 10 is arranged below the step chain 20 of the escalator 200. In the direction pointing from the step chain 20 to the oil blocking assembly 10, the projection of the oil blocking assembly 10 can cover the projection of the guide rail support plate 28 located below the oil blocking assembly 10 and the projection of part of the cross beam 27 of the escalator 200.

[0053] It can be understood that the lubricating oil on the step chain 20 will drip onto the oil retaining assembly 10 under the action of gravity. Through the shielding effect of the oil retaining assembly 10, the lubricating oil can be prevented from dripping onto the guide rail support plate 28 and the cross beam 27 of the truss below the step chain 20, thereby avoiding the pollution of the internal structure of the escalator 200 by the lubricating oil and preventing the leakage of the lubricating oil to the outside and causing environmental pollution.

[0054] Further, the oil retaining assembly 10 includes a first mounting portion 103 and at least one first oil guiding portion 104 both connected to the first mounting portion 103. The first mounting portion 103 is used for mating with the escalator 200, and each first oil guiding portion 104 protrudes outside the guide rail support plate 28 of the escalator 200 below it and is inclined downward along the direction of gravity.

[0055] It can be understood that the first mounting portion 103 and the first oil guiding portion 104 cooperate with each other to cover the guide rail support plate 28 and the cross beam 27 of the truss below the step chain 20. In this way, the lubricating oil dripping from the step chain 20 will fall onto the first mounting portion 103 and the first oil guiding portion 104, thereby avoiding the pollution of the internal structure of the escalator 200 by the lubricating oil. Subsequently, the lubricating oil dripping onto the first mounting portion 103 will flow to the first oil guiding portion 104, and the first oil guiding portion 104 can guide the lubricating oil to flow downward along the direction of gravity to a preset position.

[0056] Wherein, the preset position refers to a position other than the layout range of the guide rail support plate 28 and the cross beam 27 where the first oil guiding portion 104 guides the lubricating oil. Exemplarily, the first oil guiding portion 104 guides the lubricating oil into a collecting device or a processing device related to the lubricating oil, so as to facilitate the centralized treatment of the lubricating oil and prevent the leakage of the lubricating oil to the outside and causing environmental pollution.

[0057] In some embodiments, please refer to Figure 1 and Figure 3 , the oil retaining device 100 further includes an oil pan 13. The oil pan 13 is mated below the cross beam 27, and in the direction where the step chain 20 and the oil retaining assembly 10 are oppositely arranged, the projection of the oil retaining assembly 10 is within the projection range of the oil pan 13. It can be understood that the lubricating oil dripping from the step chain 20 will drip onto the oil pan 13 after being guided and discharged by the first oil guiding portion 104, and the oil pan 13 can prevent the leakage of the lubricating oil to the outside and causing environmental pollution.

[0058] In some embodiments, please refer to Figure 3 、 Figure 4 and Figure 8 , the oil retaining assembly 10 includes a first oil retaining member 101. The first oil retaining member 101 includes a first mounting portion 103 and two first oil guiding portions 104. The opposite ends of the first mounting portion 103 are bent toward the opposite sides in the direction of its own thickness to respectively form two first oil guiding portions 104.

[0059] It can be understood that during the assembly of the first oil baffle 101, one end of the guide rail support plate 28 close to the step chain 20 needs to be clamped into the included angle formed by bending between a first oil guiding portion 104 and a first mounting portion 103, so that the first oil guiding portion 104 and the first mounting portion 103 cooperate with each other to cover the guide rail support plate 28, so as to prevent the lubricating oil dripping from the step chain 20 from falling onto the guide rail support plate 28. Further, the first mounting portion 103 is fixedly attached to the outer surface of the guide rail support plate 28 to achieve stable assembly of the first oil baffle 101 and the guide rail support plate 28. After the assembly of the first oil baffle 101 is completed, the two first oil guiding portions 104 protrude from the opposite sides of the guide rail support plate 28 and incline downward along the direction of gravity. The two first oil guiding portions 104 and the first mounting portion 103 cooperate with each other to cover the cross beam 27 corresponding to the guide rail support plate 28 in the direction pointing from the step chain 20 to the oil baffle assembly 10. In this way, the two first oil guiding portions 104 can guide the lubricating oil outside the layout range of the guide rail support plate 28 and the cross beam 27, thereby preventing the internal structure of the escalator 200 from being contaminated by the lubricating oil.

[0060] It should be noted that since different parts of the step chain 20 are assembled with different assembly structures and different parts of the step chain 20 have different inclination angles, the dripping position of the lubricating oil will be affected. Therefore, the assembly position of the oil baffle assembly 10 needs to comprehensively consider the specific structure of the step chain 20 and the dripping position of the lubricating oil.

[0061] Therefore, in some embodiments of the present application, the first oil baffle 101 is generally arranged below the lower part of the step chain 20. It can be understood that if the lower part of the step chain 20 extends horizontally, the lubricating oil dripping from the lower part of the step chain 20 will directly drip downward along the direction of gravity. Thus, in the present application, the first oil baffle 101 is assembled below the guide rail support plate 28 corresponding to the lower part of the step chain 20 to cover the guide rail support plate 28 and the cross beam 27 through the first oil baffle 101, thereby preventing the guide rail support plate 28 and the cross beam 27 from being contaminated by the lubricating oil.

[0062] Based on this, in some other embodiments, please refer to Figure 3 、 Figure 5 and Figure 9 , the oil baffle assembly 10 further includes a second oil baffle 102. The second oil baffle 102 includes a first mounting portion 103 and a first oil guiding portion 104. One end of the first mounting portion 103 is bent to form the first oil guiding portion 104.

[0063] It is understandable that the second oil stopper 102 needs to be arranged below the lower R portion of the step chain 20. The lower R portion of the step chain 20 is affected by the arc surface and gravity, and the lubricating oil will drip from the lower point of the lower R portion of the step chain 20, and the position where the lubricating oil drips is located on the side of the guide rail support plate 28 facing upward at the lower R portion of the step chain 20. Therefore, the first mounting portion 103 of the second oil stopper 102 needs to be correspondingly assembled on the side of the guide rail support plate 28 facing upward, and the first oil guide portion 104 protrudes from the side of the guide rail support plate 28 facing upward and tilts downward along the direction of gravity. In this way, the lubricating oil dripping from the lower R portion of the step chain 20 will drip onto the first mounting portion 103, and flow from the first mounting portion 103 to the first oil guide portion 104, and finally guided to the outside of the layout range of the guide rail support plate 28 and the crossbeam 27 through the first oil guide portion 104, thereby preventing the lubricating oil from contaminating the internal structure of the escalator 200.

[0064] In some other embodiments, see Figure 3 , Figure 5 and Figure 10 The oil blocking assembly 10 further includes a second oil blocking member 102, which includes a first mounting portion 103 and a first oil guiding portion 104, and one end of the first mounting portion 103 is bent to form the first oil guiding portion 104. A mounting opening 1031 is provided on the first mounting portion 103 of the second oil blocking member 102, and the mounting opening 1031 extends along the longitudinal direction of the first mounting portion 103 and passes through one end of the first mounting portion 103 away from the first oil guiding portion 104, and the mounting opening 1031 is used for the C-shaped material 22 at the bottom of the chain guide rail 21 of the escalator 200 to be inserted.

[0065] It is understandable that the upper part of the step chain 20 and the lower part of the upper R part are both equipped with a chain guide 21, and the bottom of the chain guide 21 is equipped with a C-profile 22. The present application achieves stable assembly of the second oil stopper 102 by correspondingly engaging the mounting opening 1031 on the first mounting part 103 with the C-profile 22 at the bottom of the chain guide 21. The lubricating oil dripping from the upper part and the upper R part of the step chain 20 can flow to the first mounting part 103 through the chain guide 21 and the C-profile 22, and then the lubricating oil on the first mounting part 103 will flow from the first mounting part 103 to the first oil guide part 104, and finally guided to the outside of the layout range of the guide support plate 28 and the crossbeam 27 through the first oil guide part 104, thereby preventing the lubricating oil from contaminating the internal structure of the escalator 200.

[0066] In some embodiments, see Figure 3 and Figure 6 The oil blocking device 100 further includes an oil guide member 11 , which includes a second mounting portion 111 and a second oil guide portion 112 , and one end of the second mounting portion 111 is bent to form the second oil guide portion 112 .

[0067] The oil guide member 11 is arranged below the joint of the inclined portion 1 rail 23 and the inclined portion 2 rail 24 of the escalator 200, the second mounting portion 111 is matched to the end of the connecting plate 25 at the joint along the inclined direction, and the second oil guide portion 112 protrudes from the end of the connecting plate 25 and extends upward along the gravity direction until it is in contact with the bottom surface of the inclined portion 1 rail 23 and the inclined portion 2 rail 24.

[0068] It can be understood that the oil guide member 11 is fitted and fixed with the connecting plate 25 at the joint through the second mounting portion 111, and the lubricating oil dripping from the joint between the inclined portion 1 rail 23 and the inclined portion 2 rail 24 will flow to the second mounting portion 111 through the connecting plate 25, and then the lubricating oil on the second mounting portion 111 will flow along the inclined direction to the end of the second mounting portion 111, and change the flow direction under the guidance of the second oil guide portion 112 and flow to outside the layout range of the support plate and the cross beam 27, thereby preventing the lubricating oil from contaminating the internal structure of the escalator 200.

[0069] In addition, the second oil guide portion 112 can directly guide the lubricating oil on the bottom surfaces of the corresponding inclined portion 1 rail 23 and the inclined portion 2 rail 24, and guide the lubricating oil to outside the layout range of the support plate and the crossbeam 27, thereby preventing the lubricating oil from contaminating the internal structure of the escalator 200.

[0070] In some embodiments, see Figure 6 and Figure 11 A notch 1111 is reserved on the second mounting portion 111 , and a side wall of the notch 1111 adjacent to the second oil guiding portion 112 gradually tilts and converges along the longitudinal direction of the second oil guiding portion 112 toward the end of the second oil guiding portion 112 .

[0071] For ease of understanding, the second mounting portion 111 is defined as having a first section 1112 and a second section 1113 relative to each other. A notch 1111 is reserved on the side of the first section 1112 facing away from the second oil guiding portion 112. The portion of the first section 1112 adjacent to the second oil guiding portion 112 is structured to form a funnel-shaped oil guiding section 1114, and the gradually converged end of the oil guiding section 1114 is toward the end of the first section 1112.

[0072] It is understandable that the notch 1111 can reduce the structural strength of the oil guide section 1114. Thus, after completing the assembly of the oil guide member 11, the user can apply force to the oil guide section 1114 to make the oil guide section 1114 bend and deform downward along the direction of gravity, so that the second oil guide portion 112 can better guide the flow of lubricating oil.

[0073] In some embodiments, see Figure 3 , Figure 7 and Figure 12The oil blocking device 100 also includes an oil collecting member 12, which includes an oil collecting portion 121, a third mounting portion 122 and a third oil guiding portion 123, and both adjacent ends of the oil collecting portion 121 are bent toward the same side of the third mounting portion 122 to respectively form the third mounting portion 122 and the third oil guiding portion 123.

[0074] The oil collecting part 12 is arranged below the ends of the inclined portion 1 rail 23 and the inclined portion 2 rail 24, the third mounting portion 122 is matched with the bow profile 26 on the bottom surfaces of the inclined portion 1 rail 23 and the inclined portion 2 rail 24, the oil collecting portion 121 is parallel to and spaced apart from the connecting plate 25 of the inclined portion 1 rail 23 and the inclined portion 2 rail 24, and the third oil guiding portion 123 is located at the end of the oil collecting portion 121 along the inclination direction of the inclined portion 1 rail 23 and the inclined portion 2 rail 24.

[0075] It can be understood that the oil collecting part 12 is fitted and fixed with the bow profile 26 on the bottom surface of the inclined part 1 rail 23 and the inclined part 2 rail 24 through the third mounting part 122, and the lubricating oil dripping from the bottom surface of the inclined part 1 rail 23 and the inclined part 2 rail 24 will flow to the third mounting part 122 through the bow profile 26, and then the lubricating oil on the third mounting part 122 will flow to the oil collecting part 121 and along the inclined direction to the end of the oil collecting part 121, and finally change the flow direction under the guidance of the third oil guide part 123 and flow to outside the layout range of the support plate and the cross beam 27, thereby preventing the lubricating oil from contaminating the internal structure of the escalator 200.

[0076] In some embodiments, see Figure 7 and Figure 12 The oil collecting member 12 further includes a fourth oil guiding portion 124, and one end of the third mounting portion 122 away from the oil collecting portion 121 is bent to form the fourth oil guiding portion 124. When the oil collecting member 12 is disposed below the ends of the inclined portion 1 rail 23 and the inclined portion 2 rail 24, the fourth oil guiding portion 124 protrudes out of the outer side of the arch profile 26 and extends upwardly in an inclined direction along the gravity direction.

[0077] It can be understood that the lubricating oil dripping from the ends of the inclined portion 1 rail 23 and the inclined portion 2 rail 24 can also drip directly onto the fourth oil guide portion 124, and then be guided to the third mounting portion 122 via the fourth oil guide portion 124, and then flow through the oil collecting portion 121 and the third oil guide portion 123 to outside the layout range of the support plate and the crossbeam 27, so as to avoid the lubricating oil contaminating the internal structure of the escalator 200.

[0078] In an embodiment where some oil baffle devices 100 further include an oil pan 13, in the direction opposite to the oil guiding member 11 along the butt joint of the inclined portion 1 rail and the inclined portion 2 rail 24, the projection of the oil guiding member 11 is within the projection range of the oil pan 13. In this way, the lubricating oil dripping from the inclined portion 1 rail and the inclined portion 2 rail 24 will drip onto the oil pan 13 after being guided and discharged by the oil guiding member 11, and the oil pan 13 can prevent the lubricating oil from leaking to the outside and causing environmental pollution.

[0079] In the direction opposite to the oil collecting member 12 along the ends of the inclined portion 1 rail and the inclined portion 2 rail 24, the projection of the oil collecting member 12 is within the projection range of the oil pan 13. In this way, the lubricating oil dripping from the inclined portion 1 rail and the inclined portion 2 rail 24 will drip onto the oil pan 13 after being guided and discharged by the oil collecting member 12, and the oil pan 13 can prevent the lubricating oil from leaking to the outside and causing environmental pollution.

[0080] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0081] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
