Abstract
Description
Technical Field
[0001] This utility model belongs to the field of elevator counterweight technology, specifically relating to an elevator counterweight with an energy storage device. Background Technology
[0002] In the field of elevator technology, the counterweight, as a crucial component of the elevator system, directly impacts the elevator's operational stability, safety, and energy efficiency through its performance and design. With the continuous development of elevator technology and the increasing demands for elevator performance, many problems inherent in traditional counterweights have become increasingly apparent, necessitating urgent improvements.
[0003] The existing elevator counterweight frame uses steel plate counterweight blocks. In order to achieve balance between the counterweight and the car, the number of counterweight blocks must reach an appropriate weight. This wastes space, and the counterweight blocks also need to be processed, which increases costs. The applicability is relatively limited.
[0004] If batteries are installed directly inside the existing elevator counterweight frame, the poor air circulation inside the elevator shaft will cause the energy storage batteries to generate a lot of heat during charging and discharging. Due to the lack of an effective heat dissipation structure, the battery temperature is prone to rise. This will not only seriously affect the battery's performance and lifespan, leading to reduced charging and discharging efficiency and accelerated capacity decay, but may also cause safety hazards such as battery thermal runaway, threatening the normal operation of the elevator and the life and property safety of passengers, thus posing a certain safety risk. Utility Model Content
[0005] The purpose of this invention is to provide an elevator counterweight frame with an energy storage device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an elevator counterweight frame with an energy storage device, comprising a counterweight frame body, a counterweight structure on the counterweight frame body, limit frames fixedly connected to both sides of the counterweight frame body, a plurality of mounting frames on the limit frames, a support structure mounted on the mounting frames, the support structure comprising two fixed bases detachably mounted on the mounting frames, a common connecting rod slidably connected to the two fixed bases, a support base fixedly connected to both ends of the connecting rod, a drive structure and a heat dissipation structure on the support base, the drive structure comprising a first rotating shaft rotatably connected to the support base, a roller fixedly connected to the outer wall of the first rotating shaft, the heat dissipation structure comprising a second rotating shaft rotatably connected to the support base, a common heat dissipation fan fixedly connected to two second rotating shafts located on the same side of the counterweight frame body, a first linkage structure on the first rotating shaft and the second rotating shaft, and a second linkage structure on the first rotating shaft.
[0007] In a preferred embodiment, the counterweight structure includes several energy storage battery bodies that are detachably installed inside the counterweight frame body, and two adjacent energy storage battery bodies are electrically connected through a power line.
[0008] In a preferred embodiment, a spring is fixedly connected to the fixed base, with one end of the spring away from the fixed base being fixedly connected to the adjacent support base, and the spring being sleeved on the outer wall of the connecting rod.
[0009] In a preferred embodiment, the support base is slidably connected to the outer wall of the mounting frame, and under the connecting action of the connecting rod, the two support bases located on the same outer wall of the mounting frame always move synchronously.
[0010] In a preferred embodiment, the first linkage structure includes a driving wheel fixedly connected to the outer wall of the first rotating shaft and a driven wheel fixedly connected to the outer wall of the second rotating shaft. The outer walls of the driving wheel and the driven wheel are provided with a first belt for transmission.
[0011] In a preferred embodiment, the diameter of the driving wheel is larger than the diameter of the driven wheel, and the diameter of the driving wheel is smaller than the diameter of the roller.
[0012] In a preferred embodiment, the second linkage structure includes a linkage wheel fixedly connected to the outer wall of the first rotating shaft, and the outer walls of the two linkage wheels are provided with the same second belt for transmission.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention, through the design of a drive structure and a heat dissipation structure, ensures that the rollers are in close contact with the inner wall of the elevator shaft. During elevator use, the rollers automatically roll, and with the cooperation of the heat dissipation structure and the second linkage structure, the heat dissipation fans on both sides of the energy storage battery body rotate rapidly, forming strong air convection on both sides of the energy storage battery body, accelerating the airflow speed, efficiently dissipating heat, ensuring that the battery operates at a suitable temperature, extending its service life, and improving charging and discharging efficiency and stability. At the same time, the various structures work together to fully utilize the kinetic energy of the elevator operation to achieve heat dissipation, without the need for additional energy input, achieving energy saving and emission reduction. Moreover, the design is compact and reasonable, reducing volume and weight while ensuring functionality, reducing the space requirements of the shaft, and improving the overall performance and adaptability of the elevator system, which has broad application prospects and market value.
[0015] This invention, through the setting of a support structure and springs, allows the rollers to move flexibly towards or away from the counterweight frame body due to the sliding connection between the connecting rod and the fixed base. With the cooperation of the springs, the support base and rollers are also limited. When the elevator shaft is uneven, the springs ensure that the rollers remain in close contact with the inner wall of the elevator shaft, thus ensuring the normal rotation of the cooling fan and providing stable heat dissipation for the energy storage battery. Furthermore, the roller position can automatically adjust according to the shaft wall conditions, effectively reducing operational sway and vibration, lowering noise, improving operational stability and safety, extending component lifespan, and reducing maintenance costs and failure rates.
[0016] This invention, by setting up an energy storage battery body and a power line, connects all the energy storage battery bodies through the power line. The energy storage battery body replaces the original counterweight, avoiding wasted space. Since the original counterweight required processing, eliminating the need for counterweight reduces costs. Furthermore, by combining energy storage with the counterweight frame, the energy storage battery body can be placed inside the counterweight frame, thus achieving the elevator's balance requirements. It can also power the elevator and even the building, achieving a win-win situation of cost savings. Attached Figure Description

[0022] The present invention will be further described below with reference to the embodiments.
[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0024] Please see Figure 1-4 This utility model provides an elevator counterweight frame with an energy storage device, including a counterweight frame body 1, a counterweight structure 2 on the counterweight frame body 1, and limit frames 101 fixedly connected to both sides of the counterweight frame body 1. Several mounting frames 4 are provided on the limit frames 101, and a support structure 5 is mounted on the mounting frames 4. The support structure 5 includes two fixed bases 501 detachably mounted on the mounting frames 4. A common connecting rod 502 is slidably connected to the two fixed bases 501. Support bases 503 are fixedly connected to both ends of the connecting rod 502. The system is equipped with a drive structure 6 and a heat dissipation structure 7. The drive structure 6 includes a first rotating shaft 601 rotatably connected to the support base 503. A roller 602 is fixedly connected to the outer wall of the first rotating shaft 601. The heat dissipation structure 7 includes a second rotating shaft 701 rotatably connected to the support base 503. The same heat dissipation fan 702 is fixedly connected to the two second rotating shafts 701 located on the same side of the counterweight frame body 1. A first linkage structure 8 is provided on the first rotating shaft 601 and the second rotating shaft 701, and a second linkage structure 9 is provided on the first rotating shaft 601.
[0025] Specifically, such as Figure 1 As shown, the counterweight structure 2 includes several energy storage battery bodies 201 that can be detachably installed inside the counterweight frame body 1. Adjacent energy storage battery bodies 201 are electrically connected through power lines 202. By setting up energy storage battery bodies 201 and power lines 202, all energy storage battery bodies 201 are connected by power lines 202. The energy storage battery bodies 201 replace the original counterweight blocks, avoiding wasted space. Since the original counterweight blocks required processing, the cost is reduced by avoiding the use of counterweight blocks. In addition, with the energy storage function, the energy storage battery bodies 201 can be placed in the space of the counterweight frame body 1, thus achieving the balance requirements of the elevator. The energy storage battery bodies 201 can also supply power to the elevator and even the building, achieving a win-win situation of cost savings.
[0026] Specifically, such as Figure 3As shown, a spring 3 is fixedly connected to the fixed base 501. The end of the spring 3 away from the fixed base 501 is fixedly connected to the adjacent support base 503, and the spring 3 is sleeved on the outer wall of the connecting rod 502. The support base 503 is slidably connected to the outer wall of the mounting frame 4. Under the connecting action of the connecting rod 502, the two support bases 503 located on the same outer wall of the mounting frame 4 always move synchronously. By setting the support structure 5 and the spring 3, and because the connecting rod 502 is slidably connected to the fixed base 501, the roller 602 can move closer to or away from the counterweight frame body 1. The flexible movement of the roller 602, in conjunction with the spring 3, can limit the movement of the support base 503 and the roller 602. When the inside of the elevator shaft is uneven, the spring 3 ensures that the roller 602 is always in close contact with the inner wall of the elevator shaft, thereby ensuring that the cooling fan 702 can rotate normally, thus providing a stable cooling effect for the energy storage battery body 201. Furthermore, the position of the roller 602 can be automatically adjusted according to the condition of the shaft wall, effectively reducing running sway and vibration, reducing noise, improving running stability and safety, extending component life, and reducing maintenance costs and failure rate.
[0027] Specifically, such as Figure 4 As shown, the first linkage structure 8 includes a drive wheel 801 fixedly connected to the outer wall of the first rotating shaft 601, and a driven wheel 802 fixedly connected to the outer wall of the second rotating shaft 701. The outer walls of the drive wheel 801 and the driven wheel 802 are provided with a first belt 803 for transmission. The diameter of the drive wheel 801 is larger than the diameter of the driven wheel 802, and the diameter of the drive wheel 801 is smaller than the diameter of the roller 602. By setting the drive wheel 801, the driven wheel 802 and the first belt 803, and setting the diameter of the drive wheel 801 to be larger than the diameter of the driven wheel 802, when the roller 602 drives the drive wheel 801 to rotate through the first rotating shaft 601, the first belt 803 can drive the cooling fan 702 to rotate rapidly through the driven wheel 802 and the second rotating shaft 701, thereby accelerating the airflow around the energy storage battery body 201, cooling the energy storage battery body 201 and ensuring the service life of the energy storage battery body 201.
[0028] Specifically, such as Figure 3 and 4 As shown, the second linkage structure 9 includes a linkage wheel 901 fixedly connected to the outer wall of the first rotating shaft 601. The outer walls of the two linkage wheels 901 are provided with the same second belt 902 for transmission. By setting the linkage wheel 901 and the second belt 902, the heat dissipation fan 702 on the side away from the elevator shaft can also rotate, thereby simultaneously dissipating heat on both sides of the energy storage battery body 201.
[0029] The working principle and usage process of this utility model are as follows: Since the connecting rod 502 is slidably connected to the fixed base 501, the roller 602 can move closer to or away from the counterweight body 1. When the inside of the elevator shaft is uneven, when the counterweight body 1 moves up and down inside the elevator shaft, the roller 602 is kept in close contact with the inner wall of the elevator shaft by the action of the spring 3. During the movement of the roller 602 in contact with the inside of the elevator shaft, it rotates. With the cooperation of the linkage wheel 901 and the second belt 902, all the first rotating shafts 601 at the same height rotate synchronously. The first rotating shaft 601 drives the second rotating shaft 701 and the cooling fan 702 to rotate through the driving wheel 801, the driven wheel 802 and the first belt 803. Since the diameter of the first belt 803 is larger than the diameter of the driven wheel 802, the cooling fan 702 can rotate rapidly, so that the air around the energy storage battery body 201 flows rapidly, thereby dissipating heat from the energy storage battery body 201.
[0030] Modular energy storage battery bodies 201 and power lines 202 are installed inside the counterweight frame body 1. The energy storage battery bodies 201 are then charged and discharged through power transmission facilities such as traveling cables or sliding contact lines. The energy storage battery bodies 201 replace the original counterweight blocks, and all energy storage battery bodies 201 are connected by power lines 202. While achieving the balance requirements of the elevator, the energy storage battery bodies 201 can also supply power to the elevator and even power electrical equipment in the building. This ensures that in the event of a power outage, the energy storage battery bodies 201 can provide emergency power to ensure power supply to the elevator or electrical equipment in the building.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
