Description

Technical Field

[0001] The present application relates to the field of elevator technology, and in particular to an elevator guide shoe mounting seat. Background Art

[0002] With the development of social economy, high-rise buildings are emerging, and elevators are becoming more and more popular. Guide shoes are an indispensable part of the elevator running track. They can fix the car on the guide rail so that the car can only move up and down without horizontal shaking. The existing elevator guide shoes are usually installed with the guide shoe main beam in a fitting connection. As the main beam and the guide rail are in contact and vibrate, the screws are easily loosened.

[0003] For example, patent number CN201820280370.9, an elevator combination guide shoe, including a guide shoe base, a sliding shoe lining and a roller assembly, wherein the sliding shoe lining is installed on the guide shoe base so that the elevator combination guide shoe has the function of a sliding guide shoe; and the roller assembly is installed on the guide shoe base so that the elevator combination guide shoe also has the function of a rolling guide shoe, and the elevator combination guide shoe also includes an adjustment bracket and an adjustment nut, the adjustment bracket is installed on the guide shoe base, and the adjustment bracket has an adjustment hole, the screw passes through the adjustment hole and the center hole of the adjustment nut, and the adjustment nut is used to adjust the distance between the roller assembly and the guide rail surface. The above device has the following deficiencies in actual use:

[0004] The device fixes the guide shoe base on the top of the elevator car and then uses screws to fix the elevator main beam and the guide shoe base. When the elevator is running, the guide rail and the guide shoe lining in the elevator main beam rub against each other, causing vibration to the elevator main beam itself. As the elevator running time increases, the vibration causes the connecting screws of the elevator main beam to loosen, greatly shortening the maintenance cycle of the guide shoe and increasing safety hazards. At the same time, the loosening of the screws further increases the vibration of the elevator main beam, thereby generating a large noise and interfering with the normal use of personnel. Utility Model Content

[0005] In order to improve the problem that the conventional elevator guide shoe mounting seat is prone to loosening, thus causing safety hazards, and generates noise that interferes with people's use, the present application provides an elevator guide shoe mounting seat.

[0009] By adopting the above technical solution, the main board is connected to the guide shoe main beam to form an internal through groove, which is arranged around the guide shoe main beam and connected to the silencer, so as to collect the noise generated by the guide rail slideway to achieve the noise reduction effect. At the same time, when the guide shoe main beam is fixed with screws, the abutment ring continuously applies thrust to both sides of the guide shoe main beam to form a clamp, thereby improving the fixing effect.

[0010] Preferably, springs are fixedly disposed on opposite sides of the two limiting rings, and abutment rings are fixedly disposed on opposite sides of the two springs.

[0011] By adopting the above technical solution, when the screw is inserted into the fixing transverse hole, the spring is squeezed so that the abutment ring abuts against the side wall of the guide shoe main beam while continuously applying thrust, thereby assisting the fixation of the guide shoe main beam.

[0012] Preferably, a clamping groove is provided on one side of the inner wall of the connecting main board adjacent to the two limiting rings, and a through groove is provided on one side of the outer surface of the connecting main board close to the clamping groove.

[0013] By adopting the above technical solution, the snap-in groove reserves installation space for the subsequent fixing of the support beam, and at the same time the through groove is connected to the silencer channel to transmit noise for easy noise reduction processing.

[0014] Preferably, a bottom groove is opened on the guide shoe main beam at the bottom of the slot, a guide shoe lining is movably inserted into the slot and the bottom groove, and support plates are fixed on both sides of the guide shoe lining on the outer surface of the guide shoe main beam.

[0015] By adopting the above technical solution, the guide shoe lining oil slot is inserted into the bottom groove surface, and the guide shoe main beam forms a protrusion through the bottom groove to clamp the guide shoe lining and keep the guide shoe lining fixed.

[0016] Preferably, a fixing plate is fixedly provided on the upper end surface of the guide shoe main beam, and an oil guide groove is provided at a position where the fixing plate is aligned with the upper end surface of the guide shoe lining.

[0017] By adopting the above technical solution, the fixing plate seals the upper end surface of the guide shoe main beam, so that the guide shoe lining is fixed in the slot, and the oil guide groove guides the lubricating oil, which is convenient for the maintenance of the guide shoe lining.

[0018] Preferably, plug-in slideways are provided on both sides of the upper surface of the fixed bottom plate, and L-shaped plug-in blocks are movably plugged into the two plug-in slideways.

[0019] By adopting the above technical solution, the L-shaped plug block is inserted and fixed in the insertion slideway, so that the support beam and the fixed bottom plate are fixed.

[0020] Preferably, support columns are fixedly disposed on the upper end surfaces of the two L-shaped plug blocks, and support beams are fixedly disposed on one side of the two support columns close to the guide shoe main beam.

[0021] By adopting the above technical solution, the bottom surface is supported to abut against the upper end surface of the fixed bottom plate, and the fixing effect of the L-shaped plug is cooperated with the angle between the fixed bottom plate and the guide shoe main beam to play a supporting role and improve stability.

[0022] Preferably, an insert plate is fixedly provided on the bottom surface of the support beam, and a longitudinal protrusion is fixedly provided on the surface of one side of the support beam and the insert plate close to the guide shoe main beam, and the longitudinal protrusion is movable with the clamping slideway.

[0023] By adopting the above technical solution, the longitudinal protrusion is clamped in the clamping slideway, so that the support beam is connected to the guide shoe main beam, and the plug-in plate is inserted into the clamping groove to connect the support beam to the connecting main board to form an integral fixation.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. Use screws to insert into the fixed horizontal holes and connect with the spring surface, and then the end of the screw is connected with the guide shoe main beam thread. When the guide shoe main beam is connected, the spring continuously applies tension to the guide shoe main beam, increasing the friction between the inner thread of the guide shoe main beam and the screw. In conjunction with the connection between the connecting plate and the fixed bottom plate, the stability of the guide shoe main beam is enhanced, effectively preventing the loosening of the screws caused by the vibration of the guide shoe lining and the guide rail;

[0026] 2. With the help of the guide shoe main beam being fixed by the abutment ring, the stability is improved to initially reduce the noise generated by friction. The reduced noise diffuses along the connecting groove to the through groove, and finally enters the silencer channel and is absorbed by the silencer surface, thereby achieving secondary silencer, effectively reducing the noise generation and facilitating the normal riding of the elevator.

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The embodiment of the present application discloses an elevator guide shoe mounting seat.

[0039] Example 1

[0040] Reference Figure 1 , 5 An elevator guide shoe mounting seat includes a fixed bottom plate 1, the fixed bottom plate 1 is in a U shape as a whole, and a muffler 5 is provided inwardly at the bottom of the lower end surface of the fixed bottom plate 1, a layer of sound insulation cotton is fixed on the surface of the muffler 5, and two plug-in slideways 6 are provided on the upper end surface of the fixed bottom plate 1 away from the muffler 5, and the plug-in slideway 6 is in an L shape (such as Figure 5 shown).

[0041] By adopting the above technical solution, the noise transmitted to the silencer 5 is absorbed by the sound insulation cotton and thus reduced. At the same time, the plug-in slide 6 is opened to reserve space for the subsequent installation of the support beam 4, and the L-shaped groove improves the fixing effect.

[0042] Reference Figure 2 , 3The two sides of the upper end surface of the fixed bottom plate 1 near the plug-in slide 6 are threadedly connected with the fixed longitudinal holes 24 of the connecting plate 27 by screws, thereby forming a fixation. A connecting main board 2 is welded and fixed between the two connecting plates 27. The connecting main board 2 is U-shaped, and a through groove 26 is provided on the side of the connecting main board 2 near the muffler 5. The through groove 26 penetrates the side wall to connect the muffler 5 with the inner surface of the connecting main board 2. A rectangular clamping groove 25 is provided on the inner surface of the connecting main board 2 at the top of the through groove 26. Limiting rings 22 are welded and fixed on both sides of the inner surface of the connecting main board 2 adjacent to the clamping groove 25. Springs 23 are fixed on the opposite side surfaces of the two limiting rings 22. Abutting rings 28 are welded and fixed on the opposite ends of the two springs 23. Fixed transverse holes 21 are separately provided on the inner surface of the connecting main board 2 located inside the ring of the limiting ring 22.

[0043] It should be noted that when the connecting plate 27 is fixedly connected to the fixed base plate 1, the width of the connecting plate 27 is greater than the width of the protrusions at both ends of the fixed base plate 1, thereby forming a space on the lower end surface of the connecting plate 27 to facilitate the subsequent installation of the guide shoe main beam 3. At the same time, the abutment ring 28 is set to be made of rubber material, and the abutment surface of the abutment ring 28 and the guide shoe main beam 3 is provided with a grid texture to increase friction.

[0044] By adopting the above technical solution, the two connecting plates 27 are fixed to the upper end surface of the fixed base plate 1 by using screws, and the two connecting plates 27 are fixedly connected to the connecting main board 2, so that the connecting main board 2 and the fixed base plate 1 are fixed as a whole. At the same time, as the screw thread is turned into the fixed transverse hole 21, the guide shoe main beam 3 installed inside the connecting main board 2 is fixed, and the abutment ring 28 is squeezed inward by the pressure of the guide shoe main beam 3, and the spring 23 is compressed by the squeezing and continuously generates a rebound force extending outward, thereby clamping the two sides of the outer surface of the guide shoe main beam 3, thereby having an auxiliary fixing effect.

[0045] Reference Figure 2 , 4 The inner surface of the connecting main board 2 is threadedly fixed with a guide shoe main beam 3. Threaded holes are provided on both sides of the guide shoe main beam 3 at positions aligned with the fixed transverse holes 21, and the threaded holes of the guide shoe main beam 3 are threadedly connected with the screws in the fixed transverse holes 21, thereby forming a fixation. A slot 31 is provided on the side of the guide shoe main beam 3 away from the connecting main board 2, and a bottom groove 35 is provided at the bottom of the slot 31. The opening of the bottom groove 35 forms bulges on both sides of the bottom of the slot 31, and a guide shoe lining 32 (the width of the guide shoe lining 32 is consistent with the width of the slot 31 and the bottom groove 35) is movably inserted from the top of the slot 31, and the bottom of the guide shoe lining 32 abuts against the bottom of the bottom groove 35. A fixing plate 33 is detachably fixed on the upper end surface of the guide shoe main beam 3 by screws, and an oil guide groove 34 is provided in the middle of the fixing plate 33 at a position aligned with the slideway of the guide shoe lining 32.

[0046] It should be noted that an oil tank for dripping lubricating oil is provided on the top of the fixed plate 33 (the oil tank is an existing conventional structure and its principle is not described in detail). The lubricating oil drips from the oil guide groove 34 to the surface of the guide shoe lining 32 to achieve a lubricating effect, thereby reducing the friction generated by the contact between the guide shoe lining 32 and the guide rail, and extending the service life of the guide shoe lining 32.

[0047] By adopting the above technical solution, the two sides of the guide shoe main beam 3 are detachably fixed to the connecting main board 2 through threaded holes. At the same time, when the guide shoe lining 32 is inserted into the slot 31, the protrusion formed by the bottom groove 35 fixes the bottom of the guide shoe lining 32, and cooperates with the fixing plate 33 on the top of the guide shoe main beam 3 to fix the top of the guide shoe lining 32, so that the guide shoe lining 32 is fixed in the slot 31 to improve stability.

[0048] Reference Figure 2 , 4 The bottom of both sides of the outer surface of the guide shoe main beam 3 are welded and fixed with support plates 38. The outer surface of the guide shoe main beam 3 is located on the side close to the connection main board 2. The bottom surface of the connecting groove 36 is flush with the upper end surface of the support plate 38, and the connecting groove 36 is connected with the through groove 26 and the silencer 5. The outer surface of the guide shoe main beam 3 is located between the two connecting grooves 36. A card-connecting slide 37 is provided.

[0049] By adopting the above technical solution, when the guide shoe main beam 3 is connected to the connecting main board 2, the two support plates 38 are movably inserted in the groove between the connecting main board 2 and the fixed base plate 1 to play a limiting role. At the same time, a space is reserved between the guide shoe main beam 3 and the connecting main board 2, so that the noise generated by the vibration of the guide shoe lining 32 is spread to the connecting groove 36 through the reserved space, and then enters the silencer 5 from the connecting groove 36, so that the noise is located inside the mounting seat and propagated.

[0050] Reference Figure 2 , 3 , 5. Two support columns 41 are inserted on the upper end surface of the fixed base plate 1. L-shaped plugs 42 are welded and fixed on the lower end surfaces of the two support columns 41, and the width of the L-shaped plugs 42 is consistent with the width of the plug-in slide 6, and the two L-shaped plugs 42 are movably inserted in the plug-in slide 6. A support beam 4 is welded and fixed on the side of the two support columns 41 close to the guide shoe main beam 3. An insert plate 43 is fixed on the lower end surface of the support beam 4. The width of the insert plate 43 is consistent with the width of the card slot 25, and the insert plate 43 is movably inserted in the card slot 25. A rectangular longitudinal protrusion 44 is fixed on the surface of the support beam 4 and the insert plate 43 close to the connection with the main board 2. The width of the longitudinal protrusion 44 is consistent with the width of the card slot 37, and the longitudinal protrusion 44 is movably inserted in the card slot 37.

[0051] By adopting the above technical solution, the longitudinal protrusion 44 is inserted into the card slide 37 to provide right-side support for the support beam 4, and the L-shaped plug block 42 is inserted into the plug slide 6 to provide left-side support and up-down support for the support beam 4, and then the plug plate 43 is inserted into the card groove 25 to make the connection fit, so that the support beam 4, the fixed bottom plate 1 and the connecting main board 2 are fixed as a whole. When the support beam 4 is fixed, the support column 41 set as an inclined surface is located within the angle between the fixed bottom plate 1 and the connecting main board 2, thereby improving the stability of the connection between the fixed bottom plate 1 and the connecting main board 2 (the left side, right side, up and down directions mentioned in this paragraph are all based on Figure 2 as a benchmark).

[0052] Among them, the device also includes a lubricating oil tank, and the guide shoe lining 32 are all existing technologies, and their structural principles are not described in detail. The model of the guide shoe lining 32 depends on the width of the installation groove of the guide shoe main beam 3 and is adjusted accordingly.

[0053] When the guide shoe liner 3 is fully inserted into the U-shaped groove of the connecting main board 2, the fixing plate 33 is fixed to the upper end surface of the guide shoe main beam 3 by screws. When the guide shoe main beam 3 is fully inserted into the connecting main board 2, the fixing transverse hole 21 is used to finally abut against the side wall of the guide shoe main beam 3 to form a clamping fixation. At the same time, the abutting ring 28 is squeezed when the guide shoe main beam 3 is inserted, so that the spring 23 is deformed and contracted. The spring 23 surrounds the fixing transverse hole 21 and continuously squeezes the two sides of the guide shoe main beam 3, increasing the friction between the thread in the connecting hole of the guide shoe main beam 3 and the surface of the screw, thereby improving the connection stability of the guide shoe main beam 3 and the connecting main board 2, and then reducing the noise generated by the vibration caused by the contact between the guide shoe main beam 3 and the guide rail.

[0054] At the same time, the connecting main board 2 is screwed into the fixed longitudinal hole 24 to form a fixed connection with the fixed bottom plate 1, and the fixed bottom plate 1 is fixed to the elevator car body by screws to form an integral fixation. When the elevator is running, the guide shoe lining 32 contacts the guide rail and generates friction. The noise generated during the friction process is weakened and propagates in the gap between the guide shoe main beam 3 and the connecting main board 2, and then enters the connecting groove 36 through the gap and then enters the silencer 5 through the through groove 26. At this time, the sound insulation cotton arranged in the silencer 5 absorbs the noise for secondary noise reduction, thereby effectively reducing the noise generated when the guide shoe contacts the guide rail.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
