Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to a strong-drive type goods elevator with stable operation. Background Art

[0002] With the acceleration of urbanization and the development of technology, the demand for internal logistics transmission in various buildings is increasing. As one of the important vertical transportation tools, utility elevators are widely used in various occasions due to their flexibility and efficiency, such as office buildings, shopping malls, hospitals and factories to transport small items. In order to ensure the safety and reliability of utility elevators, the maintenance of its core component "elevator guide rails" is crucial.

[0003] Traditionally, in order to reduce friction and improve the stability of elevator operation, operators will regularly apply lubricating oil to the surface of elevator guide rails. However, over time, these lubricants will gradually absorb dust and other impurities in the air, causing the lubricating oil to deteriorate or even solidify. This situation not only fails to effectively reduce friction, but may also cause additional mechanical resistance due to the accumulation of oil, thus affecting the normal operation of the elevator and increasing safety hazards.

[0004] The existing maintenance methods mainly rely on manual inspection and regular maintenance. Specifically, professional technicians decide when to perform cleaning tasks based on a pre-set schedule or experience. This method has several obvious limitations: first, it lacks real-time performance. Regular maintenance cannot respond to changes in the actual condition of the guide rail in a timely manner, which may result in problems not being handled in a timely manner; second, it wastes resources. Regardless of whether the guide rail needs maintenance, it will be carried out according to a fixed cycle, which undoubtedly increases unnecessary costs.

[0005] In response to the above problems, we propose a stable strong-drive cargo elevator. This strong-drive cargo elevator can continuously monitor the status of the guide rails during the operation of the elevator. Once an abnormal situation is found (such as lubricating oil solidification, foreign matter deposition, etc.), the guide rails will be cleaned immediately to maintain the good performance of the guide rails and ensure that the elevator is always in a stable operating state. Summary of the invention

[0006] In order to overcome the shortcomings of the existing maintenance method that mainly relies on manual inspection and regular maintenance, lacks real-time performance and wastes resources, the present invention provides a stable forced-drive cargo elevator.

[0014] The beneficial effects of the present invention are as follows: 1. The motor can reel in or unwind the steel cable to 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 remain in contact with the inner side of the guide rail. The lubricating oil in a normal state is in a flowable state and will not squeeze the roller. If the lubricating oil solidifies, foreign matter is deposited, etc. in the guide rail, the solidified lubricating oil or foreign matter and other impurities will squeeze the roller to move, thereby controlling the cleaning plate to slide right to fit the guide rail and scrape off the impurities on the guide rail. When the roller is no longer squeezed by the impurities, the cleaning plate will slide left and reset to separate from the guide rail, avoiding the cleaning plate from scraping off the normal lubricating oil and causing waste of resources. The roller will also move to the right and fit the guide rail again, thereby monitoring the guide rail status in real time to ensure that the elevator is always in a stable operating state.

[0015] 2. The contact frame and the extrusion block are squeezed together to control the sliding plate to slide backward to 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 into the lubricating oil and then roll onto the guide rail, which can further reduce friction and improve the stability of the elevator operation.

[0016] 3. When the lubricating oil in the oil storage cylinder is empty, the closing plate will be squeezed upward by the air. The distance sensor can send out a warning signal after detecting that the closing plate is upward, thereby reminding the staff that the lubricating oil is empty. After the closing plate slides upward, the oil storage cylinder can be depressurized through the pressure relief pipe to avoid damage caused by excessive 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 barrel. The lubricating oil can be evenly spread through the coating barrel to avoid abnormal noise caused by friction of the steel cable and further improve the stability of the elevator operation.

The left and right sides of the bracket 1 are fixedly connected to the front and rear symmetrical guide rails 2, the guide rails 2 are slidably connected to the slider 3, the side of the slider 3 close to the guide rail 2 is rotatably connected to the rollers 301 distributed equidistantly, the car 4 is connected between the four sliders 3, the upper part of the bracket 1 is fixedly connected to two mounting shafts 5, the mounting shafts 5 are rotatably connected to the guide wheels 6, the lower part of the bracket 1 is fixedly connected to the motor 8, and the motor 8 A steel cable 7 is wound on the output shaft, and the tail end of the steel cable 7 is connected to the upper side of the car 4 by passing through two guide wheels 6. Cleaning plates 9 are slidably connected to the upper and lower sides of the slider 3, and fixed blocks 10 are fixedly connected to the upper and lower sides of the slider 3. The fixed block 10 is rotatably connected to a swing plate 11, and a roller 111 is rotatably connected to the side of the swing plate 11 away from the slider 3, and the roller 111 fits the inner side of the guide rail 2. A torsion spring 12 is connected between the swing plate 11 and the fixed block 10, and a connecting block 13 is movably connected to the side of the swing plate 11 close to the slider 3, and the connecting block 13 is fixedly connected to the cleaning plate 9. A lubrication component for uniformly lubricating various parts of the guide rail 2 is provided on the car 4 and the slider 3.

[0036] When the device is used, the motor 8 can reel in or unwind the steel cable 7 to 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 in the guide rail 2, and the roller 301 will also follow the slider 3 to contact the guide rail 2 and roll up and down to guide the lifting of the car 4 to ensure that the car 4 is stably lifted. When the car 4 drives the slider 3 and the roller 301 to move up and down, the lubrication 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. The roller 111 will maintain a state of being in contact with the inner side of the guide rail 2 during the up and down movement. Under normal circumstances, the lubricating oil in a normal state is in a flowable state and will not squeeze the roller 111. If the lubricating oil solidifies, foreign matter is deposited, etc. in the guide rail 2, the solidified lubricating oil or foreign matter and other impurities will squeeze the roller 111 to move to the side close to the car 4. Here, Figure 4 Taking the direction in as an example, the roller 111 moves to the left, driving 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 is deformed, and the lower part of the swing plate 11 swings to the right, driving the cleaning plate 9 to slide to the right, and the cleaning plate 9 slides to the right and fits the guide rail 2, and then scrapes off the impurities on the guide rail 2. When the roller 111 is no longer squeezed by the impurities, under the action of the torsion spring 12 resetting, the swing plate 11 reverses and resets accordingly. The reversal of the swing plate 11 drives the cleaning plate 9 to slide to the left and reset, and the cleaning plate 9 slides to the left and separates from the guide rail 2 to avoid the cleaning plate 9 scraping off the normal lubricating oil and causing a waste of resources. The reversal of the swing plate 11 will also drive the roller 111 to move to the right and fit the guide rail 2 again, thereby monitoring the status of the guide rail 2 in real time to ensure that the elevator is always in a stable operating state.

Two symmetrical 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 connected to the feed pipe 141. The cover 142 is connected to the feed pipe 141 through a thread. Two symmetrical sliding plates 143 are slidably connected in the oil storage cylinder 14. The first spring 144 is connected between the left and right sliding plates 143. The middle part of the oil storage cylinder 14 is connected to the air release pipe 145. The left and right sides of the oil storage cylinder 14 are both connected to the oil delivery pipe 15. The slider 3 is fixedly connected to the oil outlet frame 16. The oil outlet frame 16 has a The outlets corresponding to the rollers 301 one by one, the oil outlet frame 16 is connected with the adjacent oil delivery pipe 15, the middle parts of the front and rear oil storage cylinders 14 are connected with a connecting pipe 17, the upper right middle part of the upper side of the car 4 is fixedly connected with a cylinder 18, the upper left part of the cylinder 18 is connected with an air inlet pipe 181 with a one-way valve, the left side of the cylinder 18 is connected with an air outlet pipe 19 with a one-way valve, the tail end of the air outlet pipe 19 is connected 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 out of 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, and equidistantly distributed extrusion blocks 23 are provided on the right guide rail 2, the extrusion block 23 is triangular, and the upper and lower sides are inclined, the front and rear ends of the contact frame 22 are provided with rotatably connected contact wheels, and the contact frame 22 is extruded and matched with the extrusion block 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.

[0040] When the device is used, after the sliding plate 143 slides back and passes under 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 be deformed. The distance sensor 27 can send out a warning signal after detecting that the closing plate 241 slides upward, thereby reminding the staff that the lubricating oil is empty. 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 enter the pressure relief pipe 26 from the air hole to be discharged for pressure relief, so as to avoid the staff failing to replenish the lubricating oil in time, and the elevator continues to run to inflate 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 third spring 25 is reset and also drives the closing plate 241 to slide downward and reset.
