可变配重电梯及液压电梯 技术领域  Variable counterweight elevator and hydraulic elevator
本发明涉及电梯领域，特别涉及一种能够在使用过程中实现配重可变 的电梯及液压电梯。  The present invention relates to the field of elevators, and more particularly to an elevator and a hydraulic elevator capable of realizing a variable weight during use.
背景技术 Background technique
传统的电梯，都会配置一个恒定质量的平衡配重。但在实际的运行过 程中，轿厢的重量与乘客和货物的质量之和是不恒定的。 由于轿厢的重量 与乘客和货物的质量之和是不断变化的， 因此当电动机操作轿厢时， 电动 机消耗大量的功率来对应可变的重量。例如： 当轿厢从低位向高位上升阶 段，若轿厢与其内的乘客和货物的总重量大于配重，多的那部分重量就要 消耗电能；若轿厢与其内的乘客和货物的总重量小于配重时，配重多出的 那部分重量所具有的高位势能就会被白白浪费。当轿厢从高位向低位下降 阶段，若轿厢与其内的乘客和货物的总重量大于配重时，轿厢与其内的乘 客和货物的总重量多出平衡配重的那部分重量所具有的高位势能就会白 白浪费；若轿厢与其内的乘客和货物的总重量小于配重时，配重多余的重 量就需要消耗电能。  Traditional elevators are equipped with a constant mass balance weight. However, in actual operation, the sum of the weight of the car and the mass of the passenger and the cargo is not constant. Since the weight of the car and the mass of the passenger and the cargo are constantly changing, when the motor operates the car, the motor consumes a large amount of power to correspond to the variable weight. For example: When the car rises from the low position to the high position, if the total weight of the passenger car and the cargo inside the car is greater than the weight, the part of the weight consumes electric energy; if the car and the total weight of the passengers and cargo inside it When it is less than the counterweight, the high potential energy of the part of the weight with excess weight will be wasted. When the car descends from the high position to the low position, if the total weight of the passenger car and the cargo inside the car and the cargo is greater than the weight, the weight of the portion of the car and the total weight of the passengers and cargo therein is more than that of the balance weight. The high potential energy is wasted; if the total weight of the passenger car and the cargo inside the car is less than the counterweight, the excess weight of the counterweight needs to consume electrical energy.

下面结合一具体实施例对本发明所述可变配重液压电梯的工作原理 进行详细说明。  The working principle of the variable weight hydraulic elevator according to the present invention will be described in detail below with reference to a specific embodiment.
本实施例以升降楼层为 15层，载重量为 1000kg的电梯为例，依据配 重块设置块数公式： N=Wp/100kg, 其中， Wp 为电梯额定载重量， 单位 为 kg。 以及配重调节机械手设置的个数公式： G=F-1 , 其中 F为电梯升降 的总层数。 本实施例选用的配重块数量为 1000kg / 100kg=10块， 每块配 重块重量为 200kg; 配重调节机械手设置 14层， 每层 10组。  In this embodiment, an elevator with a lifting floor of 15 layers and a carrying capacity of 1000 kg is taken as an example, and the formula of the number of blocks is set according to the weight: N=Wp/100kg, where Wp is the rated load of the elevator, and the unit is kg. And the number formula of the weight adjustment manipulator setting: G=F-1, where F is the total number of elevator lifts. The weight of the weights selected in this embodiment is 1000kg / 100kg = 10 pieces, and the weight of each weight is 200kg; the weight adjustment manipulator is set up with 14 layers, 10 sets per layer.
当电梯轿厢 2未载客或货物时， 且处于最低位置时， 此时液压缸 11 的活塞 12顶端及设置在配重托架 15上的配重块 6均处于最高位置。当轿 厢 2内有乘客或货物时， 如重量传感器 8测得重量为 500kg, 则说明此时 平衡配重的 2000kg重量偏大， 并将重量 500kg的数据信号传输给控制装 置 9, 经控制装置 9运算后得出需配重减少 1000kg最为匹配， 此时控制 装置 9输出控制指令经控制电路使得与最上端的配重调节机械手 7相连的 电磁阀 10通电， 进而最上层的五排配重调节机械手 7的执行手指伸出装 卡住最上层的五个配重块 6 ,其余配重块 6随配重托架 15和活塞 12—起 向下运行， 轿厢 2向上运行。  When the elevator car 2 is not carrying passengers or cargo, and is at the lowest position, the top end of the piston 12 of the hydraulic cylinder 11 and the weight 6 disposed on the weight bracket 15 are at the highest positions. When there is passenger or cargo in the car 2, if the weight measured by the weight sensor 8 is 500kg, it means that the weight of the balance weight 2000kg is too large, and the data signal of the weight 500kg is transmitted to the control device 9, via the control device. After the operation of 9, the weight of the required weight is reduced by 1000kg. At this time, the control device 9 outputs a control command via the control circuit to energize the solenoid valve 10 connected to the uppermost weight adjustment robot 7, and then the uppermost five-row weight adjustment robot The execution fingers of 7 extend out to clamp the five weights 6 of the uppermost layer, and the remaining weights 6 run downward with the weight bracket 15 and the piston 12, and the car 2 runs upward.
当轿厢 2运行到某一层时， 轿厢 2内乘客或货物发生变化而减少时， 若此时重量传感器 8测得的重量为 300kg,则说明此时平衡配重的质量还 是偏大， 然后将该数据传输给控制装置 9, 经运算后需配重减少 600kg最 为匹配。控制装置 9输出控制指令给经控制电路使得该层的第六、七、八 排三个电磁阀 10通电， 在电磁阀的驱动下相应的三排配重调节机械手 7 的执行手指伸出卡住相应的三排配重块 6, 其余配重块 6随配重托架 15 和活塞杆 12—起向下运行， 轿厢 2继续向上运行， 直到轿厢 2运行到最 顶层。 当轿厢 2从最高位置向下运行时，不管轿厢 2与其内的乘客或货物 的总重量与平衡配重的重量是否匹配，在液压缸的活塞上行时，均将留在 各层的配重块 6提升到最高位置，其过程中各配重调节机械手 7伸出的执 行手指均由配重块 6压回原处。 这里要说明的是： 电磁阀 10在驱动所述 执行手指伸出为短时气动压出或液压压出，其余时间为无气压或液压即处 于畅通状态， 因为执行手指的端部为楔形， 当它卡住所述配重块 6后， 配 重块就不会脱落， 当液压缸 11的活塞 12上行时， 电磁阀 10处于无气压 或液压的状态时， 执行手指会很容易回复原位， 脱开配重块。 When the car 2 runs to a certain layer, when the passenger or cargo in the car 2 changes and decreases, if the weight measured by the weight sensor 8 is 300 kg at this time, the mass of the balance weight is still too large. The data is then transmitted to the control device 9, and after calculation, the weight is reduced by 600 kg to match the most. The control device 9 outputs a control command to the control circuit to energize the sixth, seventh, and eighth rows of the three solenoid valves 10 of the layer, and the execution of the corresponding three rows of the weight adjustment robot 7 is extended by the solenoid valve. Corresponding three rows of counterweights 6, the remaining counterweights 6 run down with the counterweight bracket 15 and the piston rod 12, and the car 2 continues to run upwards until the car 2 runs to the topmost level. When the car 2 runs downward from the highest position, regardless of whether the weight of the car 2 and the total weight of the passenger or cargo therein and the balance weight match, when the piston of the hydraulic cylinder is ascending, it will remain in the layers. The weight 6 is raised to the highest position, and the weight adjustment robot 7 is extended in the process. The fingers are pressed back by the weight 6 to the original position. It should be noted that: the solenoid valve 10 is pneumatically pressed or hydraulically pressed when the execution finger is extended for a short time, and the other time is no air pressure or hydraulic pressure is in a clear state, because the end of the finger is wedge-shaped, when When it is stuck with the weight 6 , the weight will not fall off. When the piston 12 of the hydraulic cylinder 11 is ascending, when the solenoid valve 10 is in a state of no air pressure or hydraulic pressure, the execution of the finger can easily return to the original position. Disengage the weight.
在电梯下行的过程中从最高位或其余位置进入轿厢 2 的乘客或货物 所具有的重力势能均转变为将各层留下的配重块 6提升所需的势能。  The gravitational potential energy of the passenger or cargo entering the car 2 from the highest or remaining position during the downward movement of the elevator is converted into the potential energy required to lift the weights 6 left by the layers.
在电梯运行过程中及停止不用的状况下， 液压缸 11的油缸发生破裂 或曳引绳 14断裂时，液压防坠落安全钳 13弹性液压输出油缸 133中的活 塞 132在弹簧 131作用下向下压将一定压力的液压油经输油管 134输入液 压防坠安全钳 13的胀力油缸 136 ,使液压防坠安全钳 13的钳口 135抱紧 钢索道轨的钢丝绳而使轿厢无法下坠， 进而保证了电梯运行的安全性。  When the cylinder of the hydraulic cylinder 11 is broken or the traction rope 14 is broken during the operation of the elevator and when it is not in use, the piston 132 in the hydraulic fall prevention safety clamp 13 of the hydraulic fall arrest safety clamp 13 is pressed downward by the action of the spring 131. The hydraulic oil of a certain pressure is input into the expansion cylinder 136 of the hydraulic anti-falling safety clamp 13 through the oil delivery pipe 134, so that the clamp 135 of the hydraulic anti-falling safety clamp 13 holds the wire rope of the cableway rail and the car cannot fall, thereby ensuring the safety. The safety of the elevator operation.
