A strongly driven freight elevator with stable operation includes a bracket. On both lateral sides inside the bracket, two longitudinally symmetric guide rails are fixedly connected. A slider is slidably connected inside the guide rail. On the side of the slider close to the guide rail, a plurality of rollers are rotatably connected at equal intervals. A car is connected between the sliders. Two mounting shafts are fixedly connected to the top end inside the bracket. When the motor winds or unwinds the steel cable, it can drive the car to move vertically up and down inside the bracket, and the slider and the rollers will also move up and down inside the guide rail. When the slider slides up and down, the roller will keep in contact with the inner side of the guide rail, so as to monitor the state of the guide rail in real time. If there are situations such as solidification of lubricating oil or deposition of foreign matters inside the guide rail, impurities such as solidified lubricating oil or foreign matters will squeeze the roller to move, and then control the cleaning plate to slide to the right to fit the guide rail, scraping the impurities on the guide rail to ensure that the elevator is always in a stable operation state.

Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and particularly to a strong-driven freight elevator with stable operation. Background Art

[0002] With the acceleration of urbanization and the development of technology, the demand for internal logistics transportation in various buildings is increasing day by day. As one of the important vertical transportation tools, freight elevators are widely used in various occasions due to their flexibility and efficiency, such as the handling of small goods in office buildings, shopping malls, hospitals, factories and other places. To ensure the safety and reliability of freight elevators, the maintenance of the core component "elevator guide rail" is crucial.

[0003] Traditionally, in order to reduce friction and improve the stability of elevator operation, operators would regularly apply lubricating oil on the surface of the elevator guide rail. However, over time, these lubricants would gradually adsorb dust and other impurities in the air, resulting in the deterioration or even solidification of the lubricating oil. This situation not only fails to effectively reduce friction, but may also cause additional mechanical resistance due to the accumulation of oil stains, thus affecting the normal operation of the elevator and increasing potential safety hazards.

[0004] The existing maintenance methods mainly rely on manual inspection and regular maintenance. Specifically, professional technicians determine when to perform cleaning tasks based on a pre-set schedule or experience. This method has several obvious limitations: one is the lack of real-time performance, and regular maintenance cannot respond in a timely manner to changes in the actual condition of the guide rail, which may lead to problems not being dealt with in a timely manner; the other is resource waste, as maintenance will be carried out according to a fixed cycle regardless of whether the guide rail needs maintenance or not, which undoubtedly increases unnecessary costs.

[0005] In view of the above problems, we propose a strong-driven freight elevator with stable operation. This strong-driven freight elevator can continuously monitor the state of the guide rail during elevator operation. Once an abnormal situation (such as solidification of lubricating oil, deposition of foreign objects, etc.) is detected, the guide rail will be cleaned immediately to maintain the good performance of the guide rail and ensure that the elevator is always in a stable operation state. Summary of the Invention

[0009] Preferably, the extrusion block is triangular in shape, with both vertical sides inclined, and both longitudinal ends of the contact frame are provided with rotatably connected contact wheels, through which the contact frame is extruded and matched with the extrusion block.

[0010] Preferably, a pressure relief assembly for relieving pressure in the oil storage cylinder is also included, the pressure relief assembly includes a sliding rod, the sliding rod is slidably connected to the cover, a closing plate is fixedly connected to the bottom end of the sliding rod, the closing plate blocks the feed pipe, a third spring is connected between the closing plate and the cover, the cover is connected to a pressure relief pipe, and the cover is fixedly connected to a distance sensor.

[0014] The beneficial effects of the present invention are as follows: 1. When the electric motor winds or unwinds the steel cable, it can drive the car to move vertically up and down inside the bracket, and the slider and the roller will also move up and down in the guide rail. When the slider slides up and down, the roller will keep in contact with the inner side of the guide rail. The lubricating oil in the normal state is in a flowable state and will not squeeze the roller. If the lubricating oil in the guide rail solidifies, foreign matters deposit, etc., the solidified lubricating oil or impurities will squeeze the roller to move, thereby controlling the cleaning plate to slide to the right and fit the guide rail, and scraping the impurities on the guide rail. When the roller is no longer squeezed by the impurities, the cleaning plate will slide to the left and reset to separate from the guide rail, avoiding the cleaning plate scraping the normal lubricating oil and causing waste of resources. The roller will also move to the right and fit the guide rail again, so as to monitor the state of the guide rail in real time and ensure that the elevator is always in a stable operation state.

[0015] 2. The contact frame and the extrusion block are in extrusion cooperation to control the sliding plate to slide backward and squeeze the lubricating oil in the oil storage cylinder into the oil outlet frame. The lubricating oil is discharged through the outlet on the oil outlet frame. When the roller rotates, it will dip the lubricating oil and then brush it onto the guide rail, which can further reduce friction and improve the stability of the elevator operation.

[0016] 3. After the lubricating oil in the oil storage cylinder is used up, the closing plate will be pushed up by the air. After the distance sensor detects that the closing plate moves up, it can send out a warning signal to prompt the staff that the lubricating oil is used up. After the closing plate slides up, the oil storage cylinder can relieve pressure through the pressure relief pipe, avoiding damage caused by too high air pressure in the oil storage cylinder.

[0017] 4. When the steel cable moves on the guide wheel, the guide wheel will also rotate to dip the lubricating oil on the coating block and contact the steel cable. When the steel cable moves, it passes through the coating cylinder, and the lubricating oil can be evenly smeared through the coating cylinder, avoiding the friction noise of the steel cable and further improving the stability of the elevator operation.

Detailed implementation manners

[0034] The following is only a preferred embodiment of the present invention, and does not limit the protection scope of the present invention accordingly.

[0035] Embodiment 1: A strongly driven freight elevator with stable operation, as Figures 1 - 5 shown, includes a bracket 1, a guide rail 2, a slider 3, a roller 301, a car 4, a mounting shaft 5, a guide wheel 6, a steel cable 7, a motor 8, a cleaning plate 9, a fixing block 10, a swing plate 11, a drum 111, a torsion spring 12, a connecting block 13 and a lubricating assembly. On both the left and right sides inside the bracket 1, symmetrically arranged front and rear guide rails 2 are fixedly connected. A slider 3 is slidably connected inside the guide rail 2. On the side of the slider 3 close to the guide rail 2, equally spaced rollers 301 are rotatably connected. A car 4 is connected between the four sliders 3. Two mounting shafts 5 are fixedly connected to the upper part inside the bracket 1. Guide wheels 6 are rotatably connected to the mounting shafts 5. A motor 8 is fixedly connected to the lower part inside the bracket 1. A steel cable 7 is wound on the output shaft of the motor 8. The tail end of the steel cable 7 bypasses the two guide wheels 6 and is connected to the upper side of the car 4. Cleaning plates 9 are slidably connected to both the upper and lower sides of the slider 3. Fixing blocks 10 are fixedly connected to both the upper and lower sides of the slider 3. Swing plates 11 are rotatably connected to the fixing blocks 10. On the side of the swing plate 11 far from the slider 3, a drum 111 is rotatably connected. The drum 111 is in contact with the inner side of the guide rail 2. A torsion spring 12 is connected between the swing plate 11 and the fixing block 10. A connecting block 13 is movably connected to the side of the swing plate 11 close to the slider 3. The connecting block 13 is fixedly connected to the cleaning plate 9. A lubricating assembly for uniformly lubricating various parts of the guide rail 2 is provided on the car 4 and the slider 3.

[0036] When using this device, the electric motor 8 winding or unwinding the steel cable 7 can drive the car 4 to move vertically up and down inside the bracket 1. When the car 4 moves up and down, the slider 3 will also slide up and down inside the guide rail 2, and the roller 301 will also roll up and down following the contact between the slider 3 and the guide rail 2 to guide the lifting of the car 4 and ensure the stable lifting of the car 4. When the car 4 drives the slider 3 and the roller 301 to move up and down, the lubricating component can add lubricating oil to the roller 301 and the guide rail 2, which can further reduce friction and improve the stability of the elevator operation. When the slider 3 slides up and down, the cleaning plate 9, the fixed block 10, the swing plate 11 and the roller 111 will also move up and down together. During the up and down movement of the roller 111, it will keep in contact with the inner side of the guide rail 2. Under normal circumstances, the lubricating oil in the normal state is in a flowable state and will not squeeze the roller 111. If the lubricating oil in the guide rail 2 solidifies, foreign matters deposit, etc., the solidified lubricating oil or foreign matters and other impurities will squeeze the roller 111 to move towards the side close to the car 4. Here, taking the direction in Figure 4 as an example, when the roller 111 moves to the left, it drives the upper part of the swing plate 11 to swing to the left, and the lower part of the swing plate 11 swings to the right. The torsion spring 12 deforms. When the lower part of the swing plate 11 swings to the right, it drives the cleaning plate 9 to slide to the right. After the cleaning plate 9 slides to the right, it fits the guide rail 2, and then scrapes the impurities on the guide rail 2. When the roller 111 is no longer squeezed by the impurities, under the action of the reset of the torsion spring 12, the swing plate 11 reverses and resets. When the swing plate 11 reverses, it drives the cleaning plate 9 to slide to the left and reset. After the cleaning plate 9 slides to the left, it separates from the guide rail 2, avoiding the cleaning plate 9 scraping the normal lubricating oil and causing waste of resources. When the swing plate 11 reverses, it will also drive the roller 111 to move to the right and re-contact the guide rail 2, so as to monitor the state of the guide rail 2 in real time and ensure that the elevator is always in a stable operation state.

[0037] Such as Figure 1 、 Figure 6 、 Figure 7 and Figure 8As shown in the figure, the lubricating assembly includes an oil storage cylinder 14, a feed pipe 141, a lid 142, a sliding plate 143, a first spring 144, a vent pipe 145, an oil delivery pipe 15, an oil outlet frame 16, a connecting pipe 17, a cylinder 18, an intake pipe 181, an exhaust pipe 19, a piston rod 20, a second spring 21, a contact frame 22, and a pressing block 23. Two symmetrically arranged oil storage cylinders 14 are fixedly connected to the upper side of the car 4. The left and right parts of the upper side of the oil storage cylinder 14 are both communicated with a feed pipe 141. A lid 142 is connected to the feed pipe 141 by means of a thread. Two symmetrically arranged sliding plates 143 are slidably connected in the oil storage cylinder 14. A first spring 144 is connected between the left and right sliding plates 143. The middle part of the oil storage cylinder 14 is communicated with a vent pipe 145. The left and right sides of the oil storage cylinder 14 are both communicated with an oil delivery pipe 15. An oil outlet frame 16 is fixedly connected inside the slider 3. The oil outlet frame 16 is provided with outlets corresponding to the rollers 301 one by one. The oil outlet frame 16 is communicated with the adjacent oil delivery pipe 15. A connecting pipe 17 is communicated between the middle parts of the front and rear oil storage cylinders 14. A cylinder 18 is fixedly connected to the upper right middle part of the car 4. The upper left part of the cylinder 18 is communicated with an intake pipe 181 with a one-way valve. The left side of the cylinder 18 is communicated with an exhaust pipe 19 with a one-way valve. The tail end of the exhaust pipe 19 is communicated with the connecting pipe 17. A piston rod 20 is slidably connected in the cylinder 18. The right part of the piston rod 20 extends outside the cylinder 18. A second spring 21 is connected between the piston rod 20 and the cylinder 18. A contact frame 22 is fixedly connected to the right side of the piston rod 20. Pressing blocks 23 are arranged at equal intervals on the right side of the guide rail 2. The pressing blocks 23 are triangular, and both the upper and lower sides are inclined. Contact wheels are rotatably connected to both the front and rear ends of the contact frame 22. The contact frame 22 is in pressing cooperation with the pressing blocks 23 through the contact wheels.

[0038] When the device is used, the car 4 and the slider 3 move up and down, which also drives the cylinder 18, the piston rod 20, the contact frame 22 and other components to move up and down. When the contact frame 22 moves to contact the extrusion block 23, the contact frame 22 is squeezed to the left by the extrusion block 23. The contact frame 22 moves to the left and drives the piston rod 20 to slide to the left. The second spring 21 is deformed, and the piston rod 20 slides to the left to squeeze the air in the cylinder 18 into the outlet pipe 19. The outlet pipe 19 then outputs the air through the connecting pipe 17. The first spring 144 is deformed, and the sliding plates 143 slide backwards to squeeze the lubricating oil in the left and right parts of the oil storage cylinder 14 into the oil delivery pipe 15. A certain amount of lubricating oil is input into the oil outlet frame 16 through the oil delivery pipe 15, and the lubricating oil is discharged through the outlet on the oil outlet frame 16. When the roller 301 rotates, it will dip into the lubricating oil, and then roll it onto the guide rail 2. When the contact frame 22 moves to a position where it is no longer squeezed, the contact frame 22 will be moved to the position where the contact frame 22 is no longer squeezed. When the contact frame 22 moves to contact with the extrusion block 23 again, the above-mentioned action is repeated to make the sliding plate 143 slide back a short distance again, and a certain amount of lubricating oil is squeezed out again to lubricate the roller 301 and the guide rail 2. When the left and right sliding plates 143 slide back to the edge of the oil storage cylinder 14, the lubricating oil in the oil storage cylinder 14 is used up. The staff can open the cover 142 and add new lubricating oil into the oil storage cylinder 14 through the feed pipe 141, and the air in the middle of the oil storage cylinder 14 can be discharged through the exhaust pipe 145. The first spring 144 is reset to drive the left and right sliding plates 143 to slide back to each other and reset. In this way, the lubricating oil can be regularly replenished after the slider 3 and the roller 301 move a certain distance, so as to ensure the lubrication effect and the uniformity of lubrication at various positions of the guide rail 2.

[0039] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 9 and Figure 10 As shown, it also includes a pressure relief assembly for relieving pressure in the oil storage cylinder 14, the pressure relief assembly includes a sliding rod 24, a closing plate 241, a third spring 25, a pressure relief pipe 26 and a distance sensor 27. The sliding rod 24 is slidably connected to the center position of the cover 142, and the closing plate 241 is fixedly connected to the lower side of the sliding rod 24. The closing plate 241 blocks the lower end of the feed pipe 141, and the third spring 25 is connected between the closing plate 241 and the cover 142. The cover 142 is connected to the pressure relief pipe 26, the lower end of the pressure relief pipe 26 is a solid structure, and the upper end of the pressure relief pipe 26 is a hollow structure. The hollow structure of the pressure relief pipe 26 is provided with an air hole, the closing plate 241 is slidably connected to the lower part of the pressure relief pipe 26, and the distance sensor 27 is fixedly connected to the cover 142.

[0040] When using this device, after the sliding plate 143 slides backward and passes below the feed pipe 141, the lubricating oil in the oil storage cylinder 14 is about to be used up. At this time, the air in the oil storage cylinder 14 will squeeze the closing plate 241 to slide upward, and the third spring 25 will deform. After the distance sensor 27 detects the upward sliding of the closing plate 241, it can send out a warning signal to prompt the staff that the lubricating oil is used up. When the closing plate 241 slides upward to the upper part of the pressure relief pipe 26, the air in the oil storage cylinder 14 can enter the feed pipe 141 and then be discharged from the air hole into the pressure relief pipe 26 for pressure relief, preventing the staff from failing to replenish the lubricating oil in time and the elevator continuing to operate and inflating the oil storage cylinder 14, resulting in damage caused by excessive air pressure in the oil storage cylinder 14. After the air in the oil storage cylinder 14 is exhausted and the pressure is relieved, the reset of the third spring 25 will also drive the closing plate 241 to slide downward and reset. When the staff opens the lid 142 to add new lubricating oil, the entire pressure relief component will also be separated from the feed pipe 141 together with the lid 142.

[0041] As Figure 1 , Figure 11 , Figure 12 and Figure 13 shown, it also includes a collection component for collecting the impurities cleaned down. The collection component includes a suction pipe 28, a delivery pipe 29, a suction pump 30, a fixed frame 31 and a collection box 32. The suction pipe 28 is connected between the two cleaning plates 9 corresponding up and down, the delivery pipe 29 is connected between the two suction pipes 28 corresponding front and back, the suction pump 30 is fixedly connected to the lower side of the car 4, the tail end of the delivery pipe 29 is connected to the suction pump 30, the fixed frame 31 is fixedly connected to the lower side of the car 4, the suction pump 30 is connected to the fixed frame 31, and the collection box 32 is slidably connected in the fixed frame 31.

[0042] When using this device, the operation of the suction pump 30 can make the suction pipe 28 suck air through the delivery pipe 29, and the impurities cleaned down by the cleaning plates 9 on the upper and lower sides can be sucked into the suction pipe 28, and then be transported into the fixed frame 31 through the delivery pipe 29 and the suction pump 30, and finally enter the collection box 32 for collection. The staff can regularly clean the impurities collected inside the collection box 32.

[0043] As Figure 1 , Figure 14 and Figure 15 shown, it also includes a coating component for lubricating the steel cable 7. The coating component includes a cover frame 33, a coating block 34, a fixing plate 35 and a coating cylinder 36. The cover frame 33 is fixedly connected to the upper side of the bracket 1, the lower side of the cover frame 33 is fixedly connected with two symmetrically arranged coating blocks 34 front and back, the coating blocks 34 are attached to the upper side of the guide wheel 6, the lower side of the rear part of the cover frame 33 is fixedly connected with two symmetrically arranged fixing plates 35 left and right, and a coating cylinder 36 is fixedly connected between the lower parts of the two fixing plates 35 left and right. The steel cable 7 passes through the coating cylinder 36.

[0044] When using this device, when the steel cable 7 moves on the guide pulley 6, the guide pulley 6 will also rotate to dip the lubricating oil on the coating block 34, so that the lubricating oil contacts the steel cable 7. When the steel cable 7 moves, it passes through the coating cylinder 36, and the lubricating oil can be evenly smeared through the coating cylinder 36, avoiding friction abnormal noise of the steel cable 7 and further improving the stability of the elevator operation.

[0045] The above has introduced this application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
