2) The operation speed is limited: the current high-speed elevator is generally 2m/s, and the ultra-high-speed elevator only achieves 5m/s.
3) The energy consumption of the elevator is huge: in the large and medium city, the energy consumption of the elevator is about 5% of the total power consumption of the whole city, the larger the city is, the higher the ratio is, and the highest ratio is even close to 8%.
In order to fundamentally overcome the defects of the existing elevators, through years of research and development, the 'flat-energy elevator' (safe and energy-saving elevator) project covering the technologies of patents 2021107209338 and 2021107219255 and the like is researched by simulation mathematics at the university of Qinghua.

1) The load time is too long, so that the riding experience is poor.
2) The fixed counterweight has overlarge mass, so that the energy consumption for acceleration and deceleration of the elevator still has a larger optimization space.
3) The guiding power is realized by crawling the main steel rail, becomes one of running vibration and noise, and increases the speed change difficulty of running machinery.
4) As the elevator speed increases, the wind resistance of the car in the hoistway becomes one of the energy costs that need to be considered.
Based on the direction of perfect optimization of the 'flat energy elevator', the 'lightweight rapid load balancing flat energy elevator' needs to realize the following purposes:
1) And (5) carrying out rapid loading, and controlling the loading time to be within 5 seconds.
2) The dead weight of the lift car is greatly reduced, and the dead weight of the lift car is controlled within 10 percent of the rated load of the lift.
3) The guiding power is realized by the small-power traction power of the machine room instead of the crawling of the main steel rail.
4) And a fairing is added to the lift car, so that the wind resistance coefficient is reduced.

Advantageous effects
Compared with the prior art, the self-lubricating heavy ball rapid loading and docking equipment has the advantages that:
1. when the elevator car stops at the corresponding floor and the weight of the elevator car becomes larger due to loading of cargoes or personnel, the first sliding door of the loading box body connected with the elevator car through the plate belt is opened, and heavy balls in the loading ball storage box enter the loading box body, so that the weight of the elevator car is basically consistent with that of the loading box body. When the weight in the car becomes light, the ball pushing mechanism of the loading box body pushes the heavy balls in the loading box body to the filling ball storage box until the weight of the car is basically consistent with that of the loading box body. The structure can lead the elevator traction power assembly to only provide smaller traction power so as to lead the car to move up and down. Because the number of heavy balls is large, the accurate adjustment of the weight can be realized, and because the travel of the heavy balls entering and exiting the loading box body is extremely short, the loading can be rapidly completed in a short time, and the running efficiency of the elevator is improved on the premise of ensuring the safe running of the elevator.
2. The loading box body and the loading ball storage box are of multi-layer structures, and after the first sliding door and the second sliding door are opened, the multi-layer heavy balls can be pushed to move at the same time, so that the travel of the heavy balls entering and exiting the loading box body is controlled within 0.25m, and the loading speed is further improved.

4. The first sliding door is in plug-in connection with the second sliding door through the electric plug pin, so that the number of driving mechanisms is reduced while the first sliding door and the second sliding door synchronously move, the structure is simplified, and the cost is reduced.
5. The second door guide rail is obliquely arranged, the gradient is 1-1.5%, the second sliding door can be closed by self gravity, and meanwhile, the resistance of the door when the door is closed in a linkage way is reduced.
6. The pin rod of the electric pin penetrates through the longitudinal strip-shaped hole to be in plug-in fit with the pin linkage sliding hole of the sliding block, so that the electric pin is allowed to have a certain degree of freedom to move up and down relative to the first sliding door when the second sliding door is in linkage switch; meanwhile, the left and right sides of the longitudinal strip-shaped hole are slightly wider than those of the plug pin, so that the electric plug pin is allowed to have a certain left and right degree of freedom so as to meet the requirement that the first sliding door and the second sliding door can be cut off from the heavy ball in sequence when the second sliding door is closed, and the resistance is reduced.
7. The outer surface of the heavy ball is provided with a self-lubricating layer; the self-lubricating layer is a polytetrafluoroethylene outer envelope, so that the flow friction resistance of heavy balls is greatly reduced; meanwhile, the body quantity of the loading system is greatly reduced, so that the novel lightweight rapid loading balancing elevator is highly adaptive to the existing elevator shaft facility.

Detailed Description
Embodiments of the present invention will now be described with reference to the accompanying drawings.
Examples
The specific embodiment of the invention is shown in fig. 1 to 12, and the self-lubricating heavy ball rapid loading and docking equipment comprises a loading box body 1, a loading ball storage box 7 and a plurality of heavy balls 6. One side of the loading box body 1 is provided with a first sliding door 2, and the first sliding door 2 is linked with a door push-pull device 4. A loading layer 15 is arranged in the loading box body 1, and a ball pushing mechanism 5 for pushing the heavy balls 6 positioned in the loading layer 15 to the loading ball storage box 7 is also arranged on the loading box body 1.
The ball pushing mechanism 5 includes a driving and reversing plate driving motor 51, a first transmission assembly 52, a driving and reversing plate driving screw 53, and a power driving and reversing plate 54, which are sequentially linked. The driving screw 53 of the driving plate is in threaded fit with the driving plate 54, and the driving plate 54 is positioned in the loading layer 15 and is in sliding fit with the loading layer 15. In this embodiment, the first transmission assembly 52 is a gear set structure, which includes a driving gear and a driven gear that are meshed with each other, the driving gear is connected to the output shaft of the driving motor 51 of the driving and reversing plates, and the driven gear is connected to the driving screw 53 of the driving and reversing plates. Both ends of the driving screw 53 of the advance and retreat plate are rotatably connected with the loading box body 1. The advance and retreat plate driving motor 51 is fixed to the loading box 1.
The door push-pull device 4 comprises a door push-pull motor 41, a second transmission assembly 45, a threaded sleeve 42 and a door push-pull screw 44 which are sequentially linked, a push-pull device bearing support 43 is arranged on the loading box body 1, and the threaded sleeve 42 is in running fit with the push-pull device bearing support 43 through a bearing. The door push-pull screw 44 is connected to the first push-pull door 2. In this embodiment, the second transmission assembly 45 adopts a gear set structure. The loading box body 1 is provided with a first door guide rail 11, and the first sliding door 2 is matched with the first door guide rail 11. The door push-pull motor 41 and the second transmission assembly 45 are both positioned in the equipment floor 14 in the loading box 1, and the door push-pull motor 41 is fixedly connected with the equipment floor 14. In this embodiment, the two first sliding doors 2 are symmetrical left and right, each first sliding door 2 is connected with a door push-pull screw 44, and the screw threads of the door push-pull screws 44 on the left and right sides are opposite in rotation direction. When the threaded sleeve 42 rotates relative to the push-pull bearing support 43, the push-pull screws 44 of the doors on the left side and the right side can be far away from each other or close to each other, so that the door opening or closing actions of the two first sliding doors 2 are realized. In this embodiment, three first door rails 11 of each first sliding door 2 are sequentially arranged from top to bottom, and the first sliding door 2 is provided with first door balls 20 in rolling fit with the first door rails 11, so that resistance is reduced.
At least two layers of loading layers 15 are arranged in the loading box body 1, and the loading layers 15 are arranged up and down. The more the number of layers of the loading layer 15 is, the narrower the widths of the loading box body 1 and the loading ball storage box 7 can be designed, and the smaller the thicknesses of the loading box body 1 and the loading ball storage box 7 can be, so that the stroke required by the entry and exit of the heavy balls 6 can be reduced, the time required by the weight adjustment of the loading box body 1 each time can be shortened, and the efficiency can be improved.
The loading ball storage box 7 comprises a ball storage box body 71, and a second sliding door 72 is connected to one side of the ball storage box body 71 facing the loading box body 1 in a sliding manner through a second door guide rail 73. A slight slope ball storage layer 741 with the bottom surface inclined towards the direction of the loading box body 1 is arranged in the ball storage box body 71. In this embodiment, the second sliding door 72 has two wings and is symmetrical. Each second sliding door 72 is correspondingly provided with three second door guide rails 73, each second door guide rail 73 is sequentially arranged from top to bottom, and the second sliding door 72 is provided with second door balls 75 in rolling fit with the second door guide rails 73, so that resistance is reduced.
The first sliding door 2 is provided with an electric latch 3, and the electric latch 3 is specifically an electromagnetic latch, and a telescopic latch rod is arranged on one side of the electric latch 3 facing the second sliding door 72. The electric bolt 3 is matched with a second sliding door 72 of the filling ball storage box 7. The second sliding door 72 is provided with a latch linkage sliding hole 721, and the electric latch 3 is in plug-in fit with the latch linkage sliding hole 721.
In this embodiment, the second door rail 73 is disposed obliquely. The latch interlock slide hole 721 is provided on a slider that is in sliding engagement with the second sliding door 72. The second sliding door 72 is also provided with a longitudinal strip-shaped hole 722, and the pin rod of the electric plug pin 3 passes through the longitudinal strip-shaped hole 722 to be in plug-in fit with a plug pin linkage sliding hole 721 of the sliding block, and the width of the longitudinal strip-shaped hole 722 is larger than that of the pin rod of the electric plug pin 3. Allowing the electric bolt 3 to have a certain degree of freedom up and down so as to realize up and down movement relative to the first sliding door 2 when the second sliding door 72 is opened and closed in a linkage manner; meanwhile, the left and right of the longitudinal strip-shaped hole 722 are slightly wider than the pin rod of the bolt, so that the pin rod of the electric bolt is allowed to have a certain left and right degree of freedom to meet the requirement that the first sliding door 2 and the second sliding door 72 can be cut off from the heavy ball 6 in a front-back mode when the second sliding door 72 is closed, and the resistance is reduced. The inclined second door rail 73 allows the two second sliding doors 72 to have a tendency to approach each other to close the door without external forces. The gradient of the second door rail 73 is 1 to 1.5% of the gradient.
At least two micro-slope ball storage layers 741 arranged up and down in the filling ball storage box 7 are separated from each other by micro-slope bearing plates 74. When the first sliding door 2 and the second sliding door 72 are opened, the gradient of the micro-slope ball storage layer 741 is not required to be too large, so that the heavy balls 6 in the filling ball storage box 7 can roll towards the direction of the loading layer 15 under the action of dead weight, and the weight gain of the loading box body 1 is effectively realized. In this embodiment, the number of layers of the micro-slope ball storage layer 741 is the same as the number of layers of the loading layer 15.
In order to reduce the thickness of the ball storage case 71 and increase the capacity of the ball storage case 71, it is necessary to increase the width of the ball storage case 71, and the width of the heavy ball inlet and outlet of the ball storage case 71 is smaller than the width of the ball storage case 71 in order to match the width of the loading layer 15 of the loading case 1. In order to ensure that all heavy balls 6 in the micro-slope ball storage layer 741 can roll out from the heavy ball inlets and outlets, the left and right ends of the micro-slope carrier plate 74 are higher than the middle part of the heavy balls, so that the heavy balls 6 positioned on the left and right ends of the micro-slope carrier plate 74 can roll towards the middle part under the action of the heavy balls, and roll out from the heavy ball inlets and outlets.
The outer surface of the heavy ball 6 is provided with a self-lubricating layer. The self-lubricating layer is a polytetrafluoroethylene outer envelope, so that the flow friction resistance of heavy balls can be greatly reduced.
The loading ball storage tank 7 can adopt a structure similar to the ball pushing mechanism 5 of the loading tank body 1 except for adopting the unpowered micro-slope ball storage layer 741, but not only the manufacturing cost is increased, but also the energy consumption is increased. Similarly, the second sliding door 72 of the loading ball storage box 7 may also be configured similar to the door slider 4 of the loading box 1, but there is a problem that the structure becomes complicated, and an additional detection sensor is required to be added to ensure that the first sliding door 2 and the second sliding door 72 can be opened and closed simultaneously.
The concrete explanation is as follows:
the maximum capacity of the loading box 1 is 1Q (Q is the rated loading capacity of the elevator), and n is set 1 Each loading layer 15, each loading layer 15 having a maximum loading q 1 ＝1Q/n 1 。
Each loading layer 15 of the loading box 1 is provided with n 2 Weight balls 6 of each row n 3 Weight balls 6, each weight ball 6 weight q 3 Minimum loading unit q 2 ＝n 3 *q 3 。
The first sliding door 2 and the second sliding door 72 are linked when the pin rod of the electric bolt 3 is ejected, and the first sliding door 2 and the second sliding door 72 are separated when the pin rod is retracted.
The rapid loading of the loading box 1 is completed by pushing out or retracting the power advance and retreat plate 54.
The maximum capacity of the filling ball storage box 7 of the standard floor is M (M=4Q, Q is the rated load capacity of the elevator), and the filling ball storage box 7 is provided with n 1 A plurality of micro-slope ball storage layers 741, wherein each micro-slope ball storage layer 741 has a maximum ball storage weight m 1 ＝M/n 1 . Normal ball weight m of standard floor loading ball storage tank 7 2 Should be controlled at 0.25m 1 <m 2 <0.75m 1 Within the range.
The maximum capacity of the filling ball storage box 7 at the topmost floor is M d (M d =10q, q is the rated load capacity of the elevator), and n is set for the loading ball storage box 7 1 A plurality of micro-slope ball storage layers 741, wherein each micro-slope ball storage layer 741 has a maximum ball storage weight m d1 ＝M d /n 1 . Normal ball weight m of the top floor loading ball storage tank 7 d2 Should be controlled at 0.25m d1 <m d2 <0.75m d1 Within the range.
The width of the heavy ball inlet and outlet of the loading ball storage box 7 is matched with that of the loading box body 1, and the gradient of 0.5-1% is set through each layer of bottom plate, so that the heavy ball 6 forms loading pressure to the heavy ball inlet and outlet of the ball storage box, and the loading pressure is controlled within 3-5 kg.
The loading box body 1 and the filling ball storage box 7 are matched to quickly complete the loading process (the time from starting loading to completing loading is controlled within 5 s):
1) Stopping the elevator;
2) The loading box body 1 is in butt joint with the floor loading ball storage box 7;
3) The pin rod of the electric bolt pops up to realize the linkage of the first sliding door and the second sliding door;
4) The first sliding door and the second sliding door are opened;
5) The elevator door starts to close and starts to load;
6) Starting each layer of power advancing and retreating plates 54 of the loading box body 1 according to the calculation result of the computer to rapidly finish pushing out or filling the heavy balls 6, thereby rapidly finishing loading;
7) The first sliding door and the second sliding door;
8) The pin rod of the electric bolt is retracted, and the loading is completed.
