Description

Technical Field

[0001] This utility model relates to the field of elevator component design technology, and in particular to an elevator sliding guide shoe. Background Technology

[0002] Elevator guide shoes, as guiding components for the elevator car and counterweight to run along the guide rails, directly affect the smoothness, comfort, noise level, and safety of elevator operation.

[0003] The existing utility model patent, such as CN205419421U entitled "An Elevator Guide Shoe", discloses a shell and an inner core. The shell includes a base plate, side frames, a fixing groove, a through hole, and a connecting groove. The side frames and the through hole are disposed on the base plate, and an assembly groove is provided between the two side frames. The connecting groove is disposed on the inner wall of the side frames. The inner core includes a core body, a fixing plate, a connecting protrusion, and a fixing block.

[0004] As mentioned above, the sliding guide shoes used in elevators have sliding friction between the shoe liner and the guide rail during actual use. Most existing guide shoes are equipped with oil drip bottles to lubricate the shoe liner and the guide rail. However, because most designs have the shoe liner and the guide rail in full contact, the lubricating oil acting on the shoe liner cannot effectively and quickly flow between the shoe liner and the guide rail when the car moves. This results in greater friction between the shoe liner and the guide rail, causing the shoe liner to wear faster. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an elevator sliding guide shoe, which solves the technical problem that the lubricating oil on the existing guide shoe cannot flow effectively and quickly between the shoe liner and the guide rail, resulting in excessive wear of the shoe liner and short service life.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An elevator sliding guide shoe includes a connecting plate and a mounting plate. The connecting plate and the mounting plate are fixedly connected to each other in an "L" shape. Two opposing fixed plates are fixed on the side of the connecting plate away from the mounting plate. A shoe liner is installed between the two fixed plates. A through groove is formed on the shoe liner, and an oil guide groove is formed at the bottom of the through groove. Lubrication grooves communicating with the oil guide groove are formed on the side walls of the through groove on both sides. Limiting members that restrict the displacement of the shoe liner are fixed on both fixed plates. Brushes are provided at the top and bottom of the connecting plate.

[0008] The present invention is further configured such that: the oil guide groove includes a first vertical groove and a plurality of guide grooves, the first vertical groove is vertically opened at the bottom of the through groove, the plurality of guide grooves are evenly opened on both sides of the first vertical groove and are all connected to the first vertical groove, and the plurality of guide grooves are opened at a downward angle on the side away from the first vertical groove and are respectively connected to the lubrication grooves on both sides.

[0009] The present invention is further configured such that: the lubrication groove includes a plurality of connecting grooves and a second vertical groove arranged in a "V" shape; the plurality of connecting grooves correspond one-to-one with a plurality of guide grooves and are vertically and evenly opened on the side wall of the through groove; one side of the plurality of connecting grooves is connected to the side of the corresponding guide groove away from the first vertical groove; the second vertical groove is vertically opened on the side wall of the through groove; the second vertical groove is connected to the side of the plurality of connecting grooves away from the guide groove.

[0010] The present invention is further configured such that: the limiting member includes an upper limiting plate and a lower limiting plate, the upper limiting plate and the lower limiting plate are fixedly mounted on the side of the fixing plate facing the boot liner, the side of the upper limiting plate facing the lower limiting plate is provided with a downwardly extending protrusion, and the side of the lower limiting plate facing the upper limiting plate is provided with an upwardly extending protrusion.

[0011] The present invention is further configured such that: the brush component includes two connecting blocks and two brush groups, the two connecting blocks are respectively disposed on the upper and lower sides of the connecting plate, and each of the two connecting blocks is provided with a brush groove that communicates with the through groove, and the two brush groups are respectively disposed in the brush grooves of the two connecting blocks.

[0012] The present invention is further configured such that: the brush group includes two brushes, the two brushes are arranged opposite each other in the brush groove, and the length of the bristles on the side away from the groove is greater than the length of the bristles on the side closer to the groove.

[0014] Compared to the beneficial effects achieved by existing technologies:

[0015] This device is an elevator sliding guide shoe, mainly used to be installed on the elevator car and slidably connected to the elevator guide rail.

[0016] By incorporating oil guide grooves and connected sidewall lubrication grooves, the distribution and retention of lubricating oil on the contact surface between the shoe liner and the guide rail are significantly optimized, effectively reducing friction and wear.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example:

[0022] Reference Figure 1 and Figure 2 This application discloses an elevator sliding guide shoe, comprising a connecting plate 1 and a mounting plate 2, which are fixedly connected to each other in an "L" shape. Both the connecting plate 1 and the mounting plate 2 are used to connect and fix to the elevator car. Two opposing fixing plates 3 are fixedly mounted on the side of the connecting plate 1 away from the mounting plate 2, and a shoe liner 4 is installed between the two fixing plates 3. The shoe liner 4 is made of rigid nylon plastic. A through groove 5 is formed on the shoe liner 4, and an oil guide groove is formed at the bottom of the through groove 5. Lubrication grooves communicating with the oil guide groove are formed on the side walls of the through groove 5 on opposite sides. The oil guide groove includes a first vertical groove 6 and several guide grooves 7. The first vertical groove 6 is vertically formed at the bottom of the through groove 5. Several guide grooves 7 are evenly formed on both sides of the first vertical groove 6 and are all connected to the first vertical groove 6. The side of several guide grooves 7 away from the first vertical groove 6 is inclined downward and communicates with the lubrication grooves on both sides. To prevent lubrication failure and serious wellbore contamination, existing oil dripping bottles (oil cans) often drip oil onto the guide shoe liner 4. The first vertical groove 6 can guide the lubricating oil dripping onto the guide shoe liner 4, and through several guide grooves 7 connected to the first vertical groove 6, the dripped lubricating oil enters the lubrication groove.

[0023] like Figure 1 and Figure 2 As shown, the lubrication groove includes several V-shaped connecting grooves 8 and a second vertical groove 9. The connecting grooves 8 correspond one-to-one with several guide grooves 7 and are vertically and evenly arranged on the sidewall of the through groove 5. One side of each connecting groove 8 connects to the side of the corresponding guide groove 7 away from the first vertical groove 6. The second vertical groove 9 is vertically arranged on the sidewall of the through groove 5 and connects to the side of each connecting groove 8 away from the guide groove 7. The V-shaped connecting grooves 8 effectively diffuse the lubricating oil entering the connecting grooves 8 through the guide grooves 7, achieving large-area lubrication between the shoe liner 4 and the guide rail. The design of the second vertical groove 9 ensures uniform and continuous distribution of lubricating oil on the sidewall of the shoe liner 4, further improving the lubrication strength between the shoe liner 4 and the guide rail.

[0024] like Figure 1 and Figure 2 As shown, both fixed plates 3 are fixed with limiting members to restrict the displacement of the boot liner 4. The limiting members include an upper limiting plate 10 and a lower limiting plate 11. The upper limiting plate 10 and the lower limiting plate 11 are fixed to the side of the fixed plate 3 facing the boot liner 4, with the upper limiting plate 10 facing the lower limiting plate 11 and having a downwardly extending protrusion 12. The lower limiting plate 11 facing the upper limiting plate 10 and having an upwardly extending protrusion 12. This arrangement limits the left and right direction of the boot liner 4 through the two fixed plates 3, effectively limits the up and down direction of the boot liner 4 through the upper limiting plate 10 and the lower limiting plate 11, and effectively limits the front and back direction of the boot liner 4 through the designed protrusion 12 and the connecting plate 1. The connecting plate 1 is also provided with an adjusting bolt 16. The adjusting bolt 16 is rotatably inserted on the connecting plate 1, and one end of the adjusting bolt 16 abuts against the center of one side of the boot liner 4. There is a gap of 0.1mm in the front-to-back direction between the boot liner 4 and several protrusions 12. Through the design of the adjusting bolt 16, after the boot liner 4 is worn due to long-term use, the adjusting bolt 16 can be screwed in to push the boot liner 4 closer to the guide rail, reduce the gap between them, and restore the appropriate contact pressure between the boot liner and the guide rail.

[0025] like Figure 1As shown, the top and bottom of the connecting plate 1 are equipped with brush components. Each brush component includes two connecting blocks 13 and two brush assemblies. The two connecting blocks 13 are fixed to the upper and lower sides of the connecting plate 1 respectively by bolts and nuts. Each of the two connecting blocks 13 has a brush groove 14 that communicates with the through groove 5. The two brush assemblies are respectively located in the brush grooves 14 of the two connecting blocks 13. Each brush assembly includes two brushes 15, which are positioned opposite each other in the brush grooves 14. The length of the bristles on the side of the two brushes 15 away from the through groove 5 is greater than the length of the bristles on the side closer to the through groove 5. The brush assembly structure designed on the upper and lower sides effectively improves the cleaning efficiency of the guide rail. The brushes 15 adopt a gradient layout, so that the long bristles on the brushes 15 can powerfully sweep away stubborn dust accumulated on the edge of the guide rail, while the short bristles avoid interference with the shoe liner 4 or the guide rail. This ensures thorough cleaning without dead corners and prevents increased running resistance or abnormal wear caused by excessively long bristles.

[0026] Working principle:

[0027] During elevator operation, lubricating oil drips from an oil bottle (oil can) into the through groove 5 area of ​​the shoe liner 4. The first vertical groove 6, located at the bottom of the through groove 5, effectively collects and guides the dripping lubricating oil vertically. The lubricating oil collected in the first vertical groove 6 is then evenly distributed and transported to the lubrication groove inlets on both sides of the through groove 5 via several guide grooves 7 connected to both sides of the first vertical groove 6. After entering the lubrication groove, the lubricating oil first flows through the "V"-shaped connecting grooves 8, achieving large-area coverage lubrication of the contact surface between the shoe liner 4 and the elevator guide rail. Subsequently, the lubricating oil flows into the vertically arranged second vertical groove 9, which connects to all the connecting grooves 8. Through the continuous diversion and distribution of the second vertical groove 9, the lubricating oil is evenly and continuously distributed across the entire side wall height of the shoe liner 4, significantly improving the overall lubrication effect and durability between the shoe liner 4 and the guide rail.

[0028] When the elevator is running, the two brushes 15, which are set opposite each other, have their bristles close to the surface of the guide rail. Through a specially designed gradient layout, the side with the bristles farther away from the through groove 5 and longer effectively sweeps away the dust accumulated on the edge and groove of the guide rail. The side with the bristles closer to the through groove 5 and shorter in length further sweeps away the dust while effectively avoiding unnecessary interference or friction with the shoe liner 4 or the guide rail body.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
