Description

Technical Field

[0001] This utility model belongs to the field of elevator technology and relates to a variable counterweight elevator based on a destination floor group control system. Background Technology

[0002] The destination floor group control system is an intelligent system for elevator management. It features intelligent scheduling, energy efficiency, and pre-leveling to await passenger arrivals. The system calculates the total weight of passengers about to enter the car, and the counterweight automatically adjusts its weight based on this information. The elevator counterweight is connected to the elevator car via traction ropes to balance the car's mass and reduce power loss in the elevator machine. Currently, the counterweight mass is fixed. When the load inside the elevator car changes, the counterweight mass cannot adjust accordingly. In this situation, the counterweight mass is no longer balanced with the total mass of the car, increasing the power loss of the elevator machine and placing relatively high demands on its performance. Utility Model Content

[0003] The purpose of this invention is to innovate the existing technology and provide a variable counterweight elevator based on a destination floor group control system. The counterweight mass can be changed according to the number and weight of the passengers being transported, so as to achieve a rebalancing of the counterweight and the car mass after carrying passengers / goods, thereby reducing the elevator's energy consumption and reducing the requirements for the traction machine's driving force.

[0004] The technical solution to achieve the above objective is: a variable counterweight elevator based on a destination floor group control system, comprising a variable counterweight installed in the elevator shaft and a sheet-like cast iron control compartment installed at each floor leveling position of the elevator, wherein:

[0005] The variable counterweight includes a fixed counterweight and a variable counterweight section disposed at its top. The variable counterweight section includes a plate-shaped cast iron counterweight compartment for accommodating vertical plate-shaped cast iron. The weight of the fixed counterweight is the same as the weight of the car itself.

[0006] Each sheet cast iron control compartment includes a sheet cast iron storage compartment, a magnetic docking mechanism, a moving slide rail mechanism, and a docking mechanism controller. The sheet cast iron storage compartment holds several vertical sheet cast irons.

The moving slide rail mechanism drives the magnetic docking mechanism to move back and forth. The sheet cast iron storage compartment can grab vertical sheet cast irons and push them into the sheet cast iron counterweight compartment, or it can grab vertical sheet cast irons from the sheet cast iron counterweight compartment and move them to the sheet cast iron storage compartment. The docking mechanism controller is located at the bottom of the sheet cast iron storage compartment. The moving slide rail mechanism is connected to the docking mechanism controller.

[0007] When the variable counterweight reaches the leveling position of each floor, the plate-shaped cast iron counterweight bin of the variable counterweight is located directly in front of the plate-shaped cast iron storage bin of the corresponding plate-shaped cast iron control bin.

[0008] The docking mechanism controller of each sheet cast iron control compartment communicates with the target layer group control system.

[0009] The aforementioned variable counterweight elevator based on a destination floor group control system includes a monitoring computer, an elevator control board, a high-definition camera installed inside the elevator, a car weighing sensor installed at the bottom of the car, and a facial recognition gate installed in the base station lobby.

[0011] The magnetic docking mechanism includes four block electromagnets, each of which is mounted on the mounting back plate via a connecting rod.

[0012] Each vertical sheet cast iron has four sheet cast iron mating interfaces, which are symmetrically distributed in pairs on the left and right sides of the vertical sheet cast iron.

[0013] The positions of the four block electromagnets are set in a one-to-one correspondence with the positions of the four sheet-shaped cast iron interfaces.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, its specific embodiments are described in detail below with reference to the accompanying drawings:

[0021] Please see Figure 1 The destination floor group control system includes a monitoring computer 102, an elevator control board 101, a high-definition camera 103 installed inside the elevator, a car weighing sensor 104 installed at the bottom of the car, and a face recognition gate 105 installed in the base station lobby. The high-definition camera 103 and the face recognition gate 105 are connected to the monitoring computer 102 via a switch. The monitoring computer 102 is connected to the CAN communication conversion module of the elevator control board 101 via RS485. The car weighing sensor 104 is connected to the elevator control board 101. The destination floor group control system can detect the number and weight of people: when passengers enter the elevator area, the face recognition gate 105 identifies and counts the passengers, recording the number of people entering the elevator area. Simultaneously, the car weighing sensor 104 installed at the bottom of the car detects the total weight of people and items inside the car in real time and transmits the data to the elevator control board 101.

[0022] Please see Figure 2 , Figure 3 and Figure 4 The preferred embodiment of this utility model is a variable counterweight elevator based on a target floor group control system, comprising a variable counterweight 2 installed in the elevator shaft 6 and a sheet-like cast iron control compartment 3 installed at each floor leveling position 5 of the elevator, wherein:

[0023] The variable counterweight 2 includes a fixed counterweight 21 and a variable counterweight section disposed at its top. The variable counterweight section includes a plate-shaped cast iron counterweight chamber 22 for accommodating vertical plate-shaped cast iron 4. The weight of the fixed counterweight 21 is the same as the weight of the car itself, and the fixed counterweight 21 can be a conventional block-type fixed counterweight. The weight of the variable counterweight 2 can be changed by adjusting the number of vertical plate-shaped cast iron 4 within the plate-shaped cast iron counterweight chamber 22.

[0024] Each sheet cast iron control compartment 3 includes a sheet cast iron storage compartment 31, a magnetic docking mechanism 32, a moving slide rail mechanism 33, and a docking mechanism controller 34. The sheet cast iron storage compartment 31 stores several vertical sheet cast iron pieces 4. The moving slide rail mechanism 33 is located inside the sheet cast iron storage compartment 31, and the magnetic docking mechanism 32 is mounted on the moving slide rail mechanism 33. The moving slide rail mechanism 33 drives the magnetic docking mechanism 32 to move back and forth. The magnetic docking mechanism 32 is used to connect the sheet cast iron storage compartment 31 to the sheet cast iron docking mechanism 4. The counterweight 22 grips the vertical sheet cast iron. Specifically, when it is necessary to increase the counterweight, the magnetic attraction docking mechanism 32 grips the vertical sheet cast iron 4 from the sheet cast iron storage bin 31 and pushes it into the sheet cast iron counterweight bin 22; when it is necessary to reduce the counterweight, the magnetic attraction docking mechanism 32 grips the vertical sheet cast iron 4 from the sheet cast iron counterweight bin 22 and pulls it into the sheet cast iron storage bin 31; the docking mechanism controller 34 is located at the bottom of the sheet cast iron storage bin 31; the moving slide rail mechanism 33 is connected to the docking mechanism controller 34.

[0025] When the variable counterweight 2 reaches the level position of each floor, the plate cast iron counterweight compartment 22 of the variable counterweight 2 is located directly in front of the plate cast iron storage compartment 31 of the corresponding plate cast iron control compartment 3, which facilitates the pushing in and moving out of the vertical plate cast iron 4.

[0026] Each sheet cast iron control compartment 3's docking mechanism controller 34 communicates with the elevator control board 101 of the target floor group control system via the CAN control communication bus 35.

[0027] The movable slide rail mechanism 33 includes an upper slide rail 331, a lower slide rail 332, a mounting back plate 333, and a drive motor 334. The upper slide rail 331 and the lower slide rail 332 are longitudinally arranged on the upper and lower inner walls of the sheet cast iron storage compartment 31 in a one-to-one correspondence. The upper and lower ends of the mounting back plate 333 are connected to the upper slide rail 331 and the lower slide rail 332 respectively through the mounting back plate guide shoes 335. The drive motor 334 drives the mounting back plate 333 to move back and forth along the upper slide rail 331 and the lower slide rail 332.

[0028] The magnetic docking mechanism 32 includes four block electromagnets 321, each of which is mounted on the mounting back plate 333 via a connecting rod 322.

[0029] Each vertical sheet cast iron 4 has four sheet cast iron interfaces 41, which are symmetrically distributed in pairs on the left and right sides of the vertical sheet cast iron 4. The positions of the four block electromagnets 321 correspond one-to-one with the positions of the four sheet cast iron interfaces 41. When the magnetic attraction docking mechanism 32 moves back and forth with the mounting back plate 333, the four block electromagnets 321 can pass through the corresponding sheet cast iron interfaces 41.

[0030] The vertical sheet cast iron 4 has a thin, rectangular structure, and the mass of one sheet cast iron is approximately equivalent to that of two adults. The sheet cast iron control compartment 3 in the non-base station layer can hold 30-50 sheet cast irons, while the sheet cast iron control compartment 3 in the base station layer can be configured according to the total number of people on the floor and in the building.

[0031] The present invention relates to a variable counterweight elevator based on a destination floor group control system. The destination floor group control system calculates the total weight of passengers about to enter the car based on the detected number and weight information of the passengers. Then, the weight of the variable counterweight 2 is changed through the sheet cast iron control compartment 3.

[0032] The variable counterweight 2 of this invention can be divided into two parts. The lower counterweight is a traditional block-type fixed counterweight, the weight of which cannot be changed and is the same as the weight of the car itself. The upper variable counterweight is a vertical plate-shaped cast iron counterweight. The vertical plate-shaped cast iron is moved horizontally out or pushed in through the magnetic attraction docking mechanism 32 of the plate-shaped cast iron control compartment 3 in the hoistway, thereby changing the weight of the entire counterweight.

[0033] At the level of each floor, a sheet-like cast iron control compartment 3 is installed. The sheet-like cast iron control compartment 3 at the counterweight position of the base station can support the largest number of vertical sheet-like cast iron 4s, while the sheet-like cast iron control compartments 3 on other floors can support fewer sheet-like cast iron 4s. The capacity of the sheet-like cast iron control compartment 3 at the counterweight position of the base station floor is approximately equal to the sum of the capacities of the sheet-like cast iron control compartments 3 on other floors.

[0034] Each sheet-like cast iron control compartment 3 is connected to the elevator control board 101 of the target floor group control system via a CAN communication bus. Based on the weight increase or decrease command issued by the elevator control board 101, the docking mechanism controller 34 of the sheet-like cast iron control compartment 3 controls the magnetic docking mechanism to move along the sliding rail mechanism, moving the vertical sheet-like cast iron 4 out of or into the counterweight. The sheet-like cast iron control compartment 3 is the driving mechanism, and the variable counterweight 2 is the driven mechanism.

[0035] This utility model discloses a variable counterweight elevator based on a destination floor group control system. The destination floor group control system calculates the total weight of passengers entering the car based on the detected number and weight information. The elevator control board 101, based on the calculation results, sends a weight increase or decrease command to the docking mechanism controller 34 of the corresponding floor's sheet-like cast iron control compartment 3 via the CAN communication bus. Upon receiving the command, the docking mechanism controller 34 of the sheet-like cast iron control compartment 3 controls the magnetic docking mechanism 32 and the moving slide rail mechanism 33 to move the vertical sheet-like cast iron 4 in or out, thereby rebalancing the counterweight with the car's mass after passenger / cargo loading. This reduces the demand on the traction machine's driving force and lowers the elevator's energy consumption.

[0036] Specifically, when it is necessary to increase the counterweight, the docking mechanism controller 34 controls the drive motor 334 to drive the mounting back plate 333 to move forward along the upper slide rail 331 and the lower slide rail 332, which drives the four block electromagnets 321 to move forward. The four block electromagnets 321 pass through the four plate cast iron docking interfaces 41 on the vertical plate cast iron 4 one by one, grab one or more vertical plate cast iron 4 pieces in the plate cast iron storage bin 31, and push the grabbed vertical plate cast iron 4 pieces into the plate cast iron counterweight bin 22. Then, the docking mechanism controller 34 controls the drive motor 334 to drive the mounting back plate 333 to move backward along the upper slide rail 331 and the lower slide rail 332 to return to the initial position.

[0037] When it is necessary to reduce the counterweight, the docking mechanism controller 34 controls the drive motor 334 to drive the mounting back plate 333 to move forward along the upper slide rail 331 and the lower slide rail 332, driving the four block electromagnets 321 to move forward. The four block electromagnets 321 pass through the four plate cast iron docking interfaces 41 on the vertical plate cast iron 4 one by one, grabbing one or more vertical plate cast iron pieces in the plate cast iron counterweight chamber 22. Then, the docking mechanism controller 34 controls the drive motor 334 to drive the mounting back plate 333 to move backward along the upper slide rail 331 and the lower slide rail 332, pulling the grabbed vertical plate cast iron 4 back into the plate cast iron storage chamber 31. Finally, the docking mechanism controller 34 controls the drive motor 334 to drive the mounting back plate 333 to move backward along the upper slide rail 331 and the lower slide rail 332 to return to the initial position.

[0038] As an improvement, each block electromagnet 321 is connected to a telescopic motor via a connecting rod 322. The telescopic motor is mounted on the mounting back plate 333, and its drive can further drive the block electromagnet to move back and forth. The telescopic motor communicates with the docking mechanism controller 34. When the block electromagnet 321 moves forward along the upper slide rail 331 and the lower slide rail 332 to its maximum limit, it can move further forward via the telescopic motor to compensate for the forward movement distance.

[0039] In summary, the variable counterweight elevator based on the destination floor group control system of this utility model can change the mass of the counterweight according to the number and weight of the passengers being transported, thereby achieving a rebalancing of the counterweight and the mass of the car after carrying passengers / goods, thus reducing the energy consumption of the elevator and reducing the requirements for the traction machine's driving force.

Any changes or modifications to the above embodiments within the scope of the essential spirit of the present utility model will fall within the scope of the claims of the present utility model.
