Problems solved by technology

Since the fixed elevator counterweight calculation rules do not consider the impact of elevator passenger flow, the factory elevator counterweight often cannot compensate for changes in car potential energy to the greatest extent, or compensates too much, or compensates too little, making the existing Elevator cannot obtain satisfactory energy-saving effect

Embodiment 1

[0025] according to figure 1 The energy-saving device for the operation of a wall-attached elevator includes a support box 1, and the inside of the support box 1 is provided with a water-filled bag 2. When the elevator is damaged and the car 7 or the counterweight 8 falls, The water bag 2 can play the role of buffering gravity, avoiding the direct fall of the car 7 and causing casualties, playing a protective role, and being safer. The top of the supporting box 1 is provided with a supporting frame 3, and the supporting frame 3 includes The first support 4, the second support 5 and the top plate 6, the first support 4 and the second support 5 are all set to two and are arranged on the front and rear sides of the top plate 6, and the second support 5 is arranged on the first support 4 On one side, the top plate 6 is arranged on the top of the first support 4 and the second support 5, the first support 4 and the second support 5 penetrate the support box 1 and are fixedly connec...

Embodiment 2

[0029] according to Figure 5 In the energy-saving device for an elevator attached to a wall, a second empty box 30 is provided at the bottom of the car 7, and one end of the U-shaped tube 10 runs through the first empty box 9 and the support box 1 to connect with the water-filled bag 2 And the other end passes through the second empty box 30 and the supporting box body 1 to be connected with the water-filled bag 2. When the weight of the car 7 is less than the counterweight 8, the second empty box 30 at the bottom of the car can be filled with water. When the weight of the car 7 is greater than that of the counterweight 8, the inside of the first empty box 9 outside the counterweight 8 can be filled with water, which is more convenient to use, and the addition of water is fast, and the elevator starts quickly. The inner wall of the second empty box 30 A receiving pipe 31 is provided, on which a second electromagnetic valve 32 is arranged, and the receiving pipe 31 corresponds...

Embodiment 3

[0031] One side of the support box 1 is provided with a PLC controller 22, and the bottom of the car 7 is provided with a load cell 23, which can detect the weight of the car 7, and the first empty box 9 and the second Empty tank 30 inside is provided with liquid level sensor 24, and liquid level sensor 24 can detect the liquid level of the liquid inside the first empty tank 9 and the second empty tank 30, thereby calculates the weight of liquid, PLC controller 22 according to load cell 23 and the data detected by the liquid level sensor 24, intelligently control the operation and operation time of the first water pump 16 and the second water pump 17, so that the counterweight 8 is adapted to the car 7, and the energy consumption of the driving device 18 is minimized. The entire elevator runs more energy-efficient.

[0032] The working principle of the present invention:

[0033] Technical solution 1: When using, refer to the attached figure 1 When the driving device 18 drives...

Abstract

The invention discloses a wall attached elevator running energy-saving device which comprises a supporting box body. A water filling bag is arranged in the supporting box body. A supporting frameworkis arranged at the top of the supporting box body and comprises first supports, second supports and a top plate. A car is arranged on the inner sides of the first supports. A balance weight is arranged on the inner sides of the second supports. A first empty box is arranged on the outer side of the balance weight. A U-shaped pipe is arranged in the first empty box and comprises an outer pipe and an inner pipe. Water outlets are arranged on the outer pipe. A connecting pipe is arranged between the inner pipe and the outer pipe and provided with a first solenoid valve. A first water pump is arranged at the end of one side of the U-shaped pipe, and a second water pump is arranged at the end of the other side of the U-shaped pipe. According to the wall attached elevator running energy-saving device, the weight in the car is detected, and therefore water in the water filling bag is drawn into the first empty box or a second empty box, the weight of the balance weight and the weight of the empty boxes are matched with the weight of the car, the work energy dissipation of a drive device is reduced, and energy saving is achieved during running of a whole elevator.

Description

technical field [0001] The invention relates to the field of elevators attached to walls, in particular to an energy-saving device for running elevators attached to walls. Background technique [0002] Because the load change in the actual operation of the elevator is related to the working environment, for the elevator with the same rated load, some elevators often work at full load, and some elevators often work at light load. If the corresponding counterweight is used, the efficiency of the elevator will be will be low. If the load of each elevator in its actual operation can be detected, the counterweight of the corresponding load can be calculated through the calculation formula of the optimal counterweight; however, due to the randomness of the elevator load, the calculated optimal counterweight The optimal counterweight may change, so it is necessary to obtain an average optimal counterweight value according to the variation trend of the optimal counterweight, and us...
