Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1, an oil cup 1 of the present embodiment is used for lubricating an elevator guide rail (not shown). The wall of the oil cup 1 is provided with a chute 9 matched with the elevator guide rail, and a plurality of electromagnetic valves 2 are arranged in the oil cup 1.
The chute 9 can be integrally formed on the oil cup 1 and is a channel formed by inwards sinking the cup wall of the oil cup 1. At least one felt 3 is arranged on the wall of the chute 9, each felt 3 corresponds to at least one electromagnetic valve 2, and the felt 3 is used for being attached to the elevator guide rail and guiding out the lubricating oil in the oil cup 1 to lubricate the elevator guide rail when the chute 9 slides along the elevator guide rail. In this embodiment, the chute 9 has two opposite side walls and a connecting wall connecting the two side walls, and a felt 3 may be disposed on both side walls and the connecting wall. And in this embodiment three solenoid valves 2 corresponding to three felts 3, respectively, may be provided.
The spring in the electromagnetic valve 2 is connected with a tongue 8, and one end of the tongue 8 penetrates through the wall of the oil cup 1 and then is connected with the corresponding felt 3. When the electromagnetic valve 2 is electrified, the spring is contracted towards the electromagnetic valve 2 due to the electromagnetic force of the electromagnetic valve 2 and drives the tongue 8 to retract so as to pull the felt 3 to be separated from the elevator guide rail, and when the electromagnetic valve 2 is deenergized, the spring is reset due to the electromagnetic force of the electromagnetic valve 2 being deenergized and drives the corresponding tongue 8 to extend so as to push the corresponding felt 3 to be attached to the elevator guide rail. The tongue 8 may be of cylindrical configuration so that the tongue 8 better passes through the wall of the oil cup 1. The tongue 8 is driven by a spring in the solenoid valve, so that the felt 3 can be attached well to the elevator guide rail.
According to the oil cup 1 of the embodiment, through the electromagnetic valve 2 arranged in the oil cup 1, the electromagnetic valve 2 drives the tongue 8, when the electromagnetic valve 2 is deenergized, the electromagnetic valve 2 loses electromagnetic force, the spring is reset, the spring pushes the tongue 8 to enable the felt 3 to be attached to the elevator guide rail, and after the felt 3 is attached to the guide rail, the whole elevator guide rail is lubricated when the felt slides along the elevator guide rail through the sliding groove 9. When the electromagnetic valve 2 is electrified, the spring is attracted by the electromagnetic valve 2 to shrink and deform, the shrinkage of the spring pulls the tongue 8 to retract, and the felt 3 is reset, so that the felt 3 is separated from the elevator guide rail, and after the felt 3 is separated from the elevator guide rail, the oil cup 1 stops lubricating the elevator guide rail. Therefore, the oil cup 1 is convenient to use, can ensure long-term stable operation of the elevator, and prolongs the service life of the elevator.
Furthermore, rail lubrication oil consumption is seasonal, and for oil consumption, the consistency of the oil is one of the main reasons. The temperature in summer is high, and the temperature of oil is high and then rises, so that the viscosity of the lubricating oil is lower than that in winter, and the felt in the oil cup 1 absorbs more oil, so that the oil consumption in summer is high. The temperature is low in winter, the temperature of oil is also low, so the viscosity of oil is high, and the oil consumption is low. Meanwhile, the viscosity of the lubricating oil is high in winter, and the oil temperature is low. The elevator is likely to be in motion because the oil viscosity causes the friction force of guide shoes and guide rails to be increased, and the elevator is in motion and has noise and poor comfort. The oil is thinner in summer and the oil temperature is high. When the felt 3 contacts the rail, the lubricating oil is more likely to run off, and the oil consumption is particularly high. Therefore, lubricating oil with high viscosity at normal temperature is selected in summer, and lubricating oil with low viscosity at normal temperature is adopted in winter.
Example 2
Referring to fig. 2 and 3, the oil cup 1 of the present embodiment is different from the oil cup 1 of embodiment 1 in that: the oil cup 1 is also provided with a control mechanism. The control mechanism comprises a top layer trigger circuit, a bottom layer trigger circuit and a controller.
The top trigger circuit comprises a magnetic stripe one 5 and a proximity switch one 4. The magnetic stripe one 5 is arranged above the wall of the elevator shaft (not shown) in which the elevator (not shown) is installed. The proximity switch I4 is arranged on the elevator and is triggered by the magnetic strip I5 to close to send out a trigger signal I when the elevator runs to the topmost layer along the elevator guide rail 10. The mounting positions of the magnetic stripe one 5 and the proximity switch one 4 are not particularly required as long as the following conditions can be satisfied: when the elevator runs to the topmost layer along the elevator guide rail 10, the first magnetic stripe 5 is positioned above the elevator shaft wall, the first proximity switch 4 is positioned at the top of the elevator car, and the first proximity switch 4 is triggered by the first magnetic stripe 5 to be closed to send out the first trigger signal.
For example, the first magnetic strip 5 is located on the wall of the elevator shaft when the elevator moves to the topmost layer along the elevator guide rail 10, and the corresponding first proximity switch 4 is arranged on the top of the elevator car, so that the first magnetic strip 5 is located above the wall of the elevator shaft when the elevator moves to the topmost layer along the elevator guide rail 10, and the first proximity switch 4 can be triggered by the first magnetic strip 5 to be closed to send a first trigger signal. In particular, the first magnetic strip 5 may be mounted on the top wall of the elevator hoistway and the first proximity switch 4 may be mounted on top of the car of said elevator.
For another example, the first magnetic stripe 5 is located above the hoistway wall when the elevator moves to the topmost floor along the elevator guide rail 10, and the corresponding first proximity switch 4 is disposed at the top of the elevator car facing the first magnetic stripe 5, so that the first proximity switch 4 is located at the top of the elevator car when the elevator moves to the topmost floor along the elevator guide rail 10, and the first proximity switch 4 can be triggered by the first magnetic stripe 5 to close and send the first trigger signal. In particular, the first magnetic strip 5 may be mounted above the wall of the elevator shaft and the first proximity switch 4 may be mounted on top of the car of said elevator corresponding to the first magnetic strip 5.
The bottom trigger circuit comprises a second magnetic stripe 7 and a second proximity switch 6. The second magnetic stripe 7 is arranged below the wall of the elevator shaft where the elevator is installed. The second proximity switch 6 is arranged on the elevator and is triggered by the second magnetic stripe 7 to close and send out a second trigger signal when the elevator runs to the bottommost layer along the elevator guide rail 10. The second magnetic stripe 7 is located below the hoistway wall when the elevator is traveling along the elevator guide rail 10 to the lowest floor. A second proximity switch 6 is provided on the bottom of the elevator.
The controller counts the times of reaching the top layer once according to the first trigger signal and counts the times of reaching the bottom layer once according to the second trigger signal. The controller also judges whether the total number of times that the elevator reaches the top layer is not less than a preset value one, if yes, the electromagnetic valve 2 is driven to be powered on, otherwise, the controller continues to judge whether the total number of times that the elevator reaches the bottom layer is not less than a preset value two, if yes, the electromagnetic valve 2 is driven to be powered on, otherwise, the controller continues to count and then re-judges. After the solenoid valve 2 is de-energized, the count of the controller may be cleared, and then the controller may repeat the entire lubrication process.
Referring to fig. 4, the intelligent lubrication method of the oil cup 1 of the present embodiment and the corresponding elevator guide rail 10 may include the following steps.
Step S11, when the elevator runs along the elevator guide rail 10 to the topmost floor, a trigger signal one is sent out. In this embodiment, the first proximity switch 4 is triggered by the first magnetic stripe 5 to close to send out the first trigger signal.
Step S12, counting to increase the times of reaching the top layer once according to the first trigger signal. In this embodiment, this step is performed by the controller.
Step S13, when the elevator runs to the lowest floor along the elevator guide rail 10, a trigger signal two is sent out. In this embodiment, the second proximity switch 6 is triggered by the second magnetic stripe 7 to close and send out the second trigger signal.
And step S14, counting to increase the number of times the elevator reaches the bottom layer once according to the second trigger signal. In this embodiment, this step is performed by the controller.
And S15, judging whether the total number of times the elevator reaches the top layer is not less than a preset value one. In this embodiment, this step is performed by the controller.
When the total number of times the elevator reaches the top floor is not less than a preset value, step S16 is performed to drive the solenoid valve 2 to be powered. In the step, the controller drives the electromagnetic valve 2 to be electrified, and after the electromagnetic valve 2 is electrified, the felt 3 is separated from the elevator guide rail 10 to stop lubricating the elevator guide rail 10.
From this, the one-time lubrication of the elevator guide rail 10 by the oil cup 1 ends. The automatic circulation lubrication of the elevator guide rail 10 by the oil cup 1 can be designed through the arrangement of the controller. If the solenoid valve 2 is powered on, step S18 is performed, and the timer is started until the time reaches a preset time. This step is performed by the controller. When the counted time reaches the preset time, step S19 is executed, the solenoid valve 2 is powered off, all counts are cleared, and step S11 is returned. In the step, the controller drives the electromagnetic valve 2 to lose electricity, after the electromagnetic valve 2 loses electricity, the felt 3 is attached to the elevator guide rail 10, and the controller clears all the counts, so that the elevator guide rail 10 starts a new lubrication process again.
When the total number of times the elevator reaches the top floor is smaller than a preset value, step S17 is executed to determine whether the total number of times the elevator reaches the bottom floor is not smaller than a preset value of two. This step is performed by the controller.
When the total number of times the elevator reaches the bottom floor is not less than a preset value two, step S16 is executed. This step is performed by the controller.
When the total number of times the elevator reaches the bottom floor is smaller than a preset value two, step S11 is executed. This step is performed by the controller.
The oil cup 1 of the present embodiment can realize periodic lubrication of the elevator guide rail 10. Thereby enabling an increase in the efficiency of use of the lubricating oil.
In other embodiments, the contents of step S15 and step S17 may be interchanged. That is, the controller firstly judges whether the total number of times that the elevator reaches the top layer is not less than a preset value two, if yes, the electromagnetic valve 2 is driven to be powered on, otherwise, the controller continues to judge whether the total number of times that the elevator reaches the bottom layer is not less than a preset value one, if yes, the electromagnetic valve 2 is driven to be powered on, otherwise, the controller continues to count and then re-judges.
Example 3
The oil cup 1 of the present embodiment differs from the oil cup 1 of embodiment 2 in that: the function of the controller is adjusted.
In this embodiment, the controller is no longer: judging whether the total number of times that the elevator reaches the top layer is not less than a preset value one, if yes, driving the electromagnetic valve 2 to be powered on, otherwise, continuously judging whether the total number of times that the elevator reaches the bottom layer is not less than a preset value two, if yes, driving the electromagnetic valve 2 to be powered on, otherwise, continuously counting and then judging again; instead, it is: and judging whether the total number of times that the elevator reaches the top layer is not less than a preset value one, if so, continuously judging whether the total number of times that the elevator reaches the bottom layer is not less than a preset value two, and if so, driving the electromagnetic valve 2 to obtain electricity.
The intelligent lubrication method of the elevator guide rail 10 of the oil cup 1 of the present embodiment is also correspondingly different from the intelligent lubrication method of the elevator guide rail 10 of the oil cup 1 of embodiment 2. Referring to fig. 5, the intelligent lubrication method of the elevator guide rail 10 of the oil cup 1 of the present embodiment includes the following steps.
Step S21, when the elevator runs along the elevator guide rail 10 to the topmost floor, a trigger signal one is issued. In this embodiment, the first proximity switch 4 is triggered by the first magnetic stripe 5 to close to send out the first trigger signal.
Step S22, counting to increase the times of reaching the top layer once according to the first trigger signal. In this embodiment, this step is performed by the controller.
Step S23, when the elevator runs to the lowest floor along the elevator guide rail 10, a trigger signal two is sent out. In this embodiment, the second proximity switch 6 is triggered by the second magnetic stripe 7 to close and send out the second trigger signal.
And step S24, counting to increase the number of times the elevator reaches the bottom layer once according to the second trigger signal. In this embodiment, this step is performed by the controller.
And S25, judging whether the total number of times the elevator reaches the top layer is not less than a preset value one. In this embodiment, this step is performed by the controller.
When the total number of times the elevator reaches the top floor is not less than a preset value, step S26 is executed to determine whether the total number of times the elevator reaches the bottom floor is not less than a preset value of two. This step is performed by the controller.
When the total number of times the elevator reaches the bottom floor is not less than a preset value two, step S27 is executed to drive the electromagnetic valve 2 to be powered. In the step, the controller drives the electromagnetic valve 2 to be electrified, and after the electromagnetic valve 2 is electrified, the felt 3 is separated from the elevator guide rail 10 to stop lubricating the elevator guide rail 10.
From this, the one-time lubrication of the elevator guide rail 10 by the oil cup 1 ends. The automatic circulation lubrication of the elevator guide rail 10 by the oil cup 1 can be designed through the arrangement of the controller. If the solenoid valve 2 is powered on, step S28 is performed, and the timer is started until the time reaches a preset time. This step is performed by the controller.
