Description
技术领域Technical field
本发明涉及工程机械技术领域,尤其涉及一种破拆机器人。The invention relates to the technical field of construction machinery, and in particular to a demolition robot.
背景技术Background technique
机器人技术是对未来新兴产业发展具有重要意义的高新技术之一。早期的机器人受限于当时的技术水平,性能很难满足当时的应用需求。随着科技的进步,近年来,国内外对于机器人技术的研究十分活跃,但在极限作业场景下的机器人的研究仍然存在不足。例如,在地震导致的建筑物坍塌、地下空间的坍塌等空间受限的场景中的救援行动中,对机器人性能的要求较高。目前市场上的多功能破拆救援机器人以大吨位类型为主,虽然能满足破拆救援能力的需求,但由于外形尺寸较大,难以进入内部救援,导致整体的救援效率低。并且由于机器人体积大、结构复杂、能耗高,其内部存在较多的热量集中区域,而散热器的尺寸有限,无法覆盖所有热源,导致某些区域难以获得充足的散热,进而导致机器人的在高负荷下作业时散热效果不佳,影响其工作效率。Robot technology is one of the high technologies that is of great significance to the development of emerging industries in the future. Early robots were limited by the technical level at the time, and their performance could hardly meet the application needs at the time. With the advancement of science and technology, research on robot technology at home and abroad has been very active in recent years. However, there are still deficiencies in the research on robots in extreme operating scenarios. For example, in rescue operations in space-constrained scenarios such as building collapse and underground space collapse caused by earthquakes, the requirements for robot performance are high. Currently, the multi-functional demolition and rescue robots on the market are mainly large-tonnage types. Although they can meet the needs of demolition and rescue capabilities, due to their large size, it is difficult to enter the internal rescue, resulting in low overall rescue efficiency. Moreover, due to the large size, complex structure and high energy consumption of the robot, there are many heat concentration areas inside the robot. The size of the radiator is limited and cannot cover all heat sources, making it difficult to obtain sufficient heat dissipation in some areas, which in turn leads to the failure of the robot. The heat dissipation effect is poor when operating under high load, which affects its work efficiency.
高能耗:功率大的机器人通常会产生更高的能耗,并且这些能量会以热量的形式释放出来。这将对散热系统提出更高的要求,需要更好的散热能力来避免过热问题。High energy consumption: Powerful robots usually consume more energy, and this energy is released in the form of heat. This will place higher demands on the cooling system, requiring better cooling capabilities to avoid overheating problems.

参考图1和3所示,在本发明提供的破拆机器人的一些实施例中,该破拆机器人包括液压系统、发动机3、散热装置和控制装置,液压系统包括液压泵1和与液压泵1连接的作业装置2,液压泵1被配置为向作业装置2输送液压油以控制作业装置2的动作;发动机3与液压泵1驱动连接;散热装置被配置为对液压系统的液压油和对发动机3的冷却液进行散热;控制装置被配置为在液压油的温度、冷却液的温度中的至少一个升高之前增大散热装置的散热功率,和/或在液压油的温度、冷却液的温度中的至少一个降低之前减小散热装置的散热功率。Referring to Figures 1 and 3, in some embodiments of the demolition robot provided by the present invention, the demolition robot includes a hydraulic system, an engine 3, a heat dissipation device and a control device. The hydraulic system includes a hydraulic pump 1 and a hydraulic pump 1 The connected working device 2 and the hydraulic pump 1 are configured to deliver hydraulic oil to the working device 2 to control the action of the working device 2; the engine 3 is drivingly connected to the hydraulic pump 1; the heat sink is configured to supply hydraulic oil to the hydraulic system and to the engine. The cooling liquid of 3 is used for heat dissipation; the control device is configured to increase the heat dissipation power of the heat dissipation device before at least one of the temperature of the hydraulic oil and the temperature of the cooling liquid increases, and/or before the temperature of the hydraulic oil and the temperature of the cooling liquid increases. At least one of them reduces the heat dissipation power of the heat dissipation device before reducing it.
通过设置散热装置对液压系统的液压油和发动机的冷却液进行散热,可以确保液压系统和发动机在运行过程中保持在适宜的温度范围内,避免由于过热或过冷所可能造成的效率降低或零部件损坏。By setting up a heat dissipation device to dissipate heat from the hydraulic oil in the hydraulic system and the engine coolant, it can ensure that the hydraulic system and engine are kept within an appropriate temperature range during operation, and avoid possible reduction or zero efficiency due to overheating or overcooling. Parts are damaged.
进一步的,通过在液压油的温度、冷却液的温度或二者之一的升高之前增大散热装置的散热功率,即实现了对温度的预先调节,从而可以尽可能地减小温度的上升范围,相比于在温度升高之后再增大散热功率进行散热,本发明可以有效避免由于温升过大而导致的效率下降或零部件损坏;通过在液压油的温度、冷却液的温度中的至少一个降低之前减小散热装置的散热功率,可以在冷却需求较低时(例如冬天外部环境温度较低时)节约能源,还可以避免因过度冷却而造成的工作性能下降。Furthermore, by increasing the heat dissipation power of the heat dissipation device before the temperature of the hydraulic oil, the temperature of the coolant, or either of the two rises, pre-conditioning of the temperature is achieved, thereby minimizing the rise in temperature. range, compared with increasing the heat dissipation power for heat dissipation after the temperature rises, the present invention can effectively avoid the decrease in efficiency or damage to parts due to excessive temperature rise; by adjusting the temperature of the hydraulic oil and the temperature of the coolant At least one reduction before reducing the cooling power of the heat sink can save energy when the cooling demand is low (for example, when the external ambient temperature is low in winter), and can also avoid the degradation of working performance caused by excessive cooling.
其中,散热装置的类型可以有多种选择,例如风冷式、液冷式等,根据实际需求选择即可。Among them, there are many types of heat dissipation devices to choose from, such as air-cooled, liquid-cooled, etc., which can be selected according to actual needs.
在一些实施例中,破拆机器人还包括用于为发动机3的启动供能的电瓶。In some embodiments, the demolition robot further includes a battery for powering the engine 3 to start.
在一些实施例中,作业装置2的负荷可调,控制装置被配置为根据作业装置2的负荷的变化调节散热装置的散热功率。In some embodiments, the load of the working device 2 is adjustable, and the control device is configured to adjust the heat dissipation power of the heat dissipation device according to changes in the load of the working device 2 .
作业装置2的负荷的变化通常意味着液压系统、发动机3等部件的输出功率发生变化,因此也会导致破拆机器人整体发热量发生变化,通过设置控制装置,能够实现根据作业装置2的负荷的变化提前预判破拆机器人的发热量,从而提前改变散热器的散热能力(即增大或减小散热功率),实现预先型的热管理,有助于让破拆机器人维持在一个较小的工作温度范围内,从而保持整机的热平衡。Changes in the load of the working device 2 usually mean changes in the output power of components such as the hydraulic system and the engine 3, which will also lead to changes in the overall calorific value of the demolition robot. By setting up a control device, it is possible to realize changes based on the load of the working device 2. Changes can predict the amount of heat generated by the demolition robot in advance, thereby changing the heat dissipation capacity of the radiator (i.e. increasing or decreasing the heat dissipation power) in advance to achieve pre-emptive thermal management, which helps to maintain the demolition robot at a smaller size. Within the operating temperature range, thereby maintaining the thermal balance of the entire machine.
这种预先型的热管理模式能够从源头上解决温度变化范围过大的问题,适用于各种规格、形状的破拆机器人,无论破拆机器人的体积大小,均能对其实现有效的温度控制。具体的,一方面能够有效避免由于破拆机器人的体积过大、散热系统覆盖不足而导致的整机温度不均匀、热点集中等问题,另一方面也能有效防止由于破拆机器人的体积紧凑而产生的不便散热、散热空间小而导致的、散热慢、超温问题。This pre-type thermal management mode can solve the problem of excessive temperature change range from the source. It is suitable for demolition robots of various specifications and shapes. It can achieve effective temperature control regardless of the size of the demolition robot. . Specifically, on the one hand, it can effectively avoid problems such as uneven temperature of the whole machine and concentrated hot spots caused by the excessive size of the demolition robot and insufficient coverage of the cooling system. On the other hand, it can also effectively prevent problems caused by the compact size of the demolition robot. The resulting inconvenient heat dissipation, small heat dissipation space, slow heat dissipation, and over-temperature problems.
在一些实施例中,破拆机器人还包括用于调节作业装置2的负荷的操作台,控制装置与操作台信号连接以获取作业装置2的负荷的变化。In some embodiments, the demolition robot further includes an operating console for adjusting the load of the working device 2 , and the control device is signal-connected to the operating console to obtain changes in the load of the working device 2 .
通过设置操作台,便于让破拆机器人的操作人员根据需要对作业装置2的负荷进行调节,从而提高破拆机器人对不同作业环境的适应能力,在不同的外部条件下均能够保持较高的作业效率。By setting up an operating platform, it is convenient for the operator of the demolition robot to adjust the load of the working device 2 as needed, thereby improving the adaptability of the demolition robot to different working environments and maintaining a high operating performance under different external conditions. efficiency.
其中,操作人员向操作台输入指令有多种方式,例如可以通过操作台的输入界面直接进行指令的输入,还可以采用无线设备对操作台进行远程操控等。Among them, there are many ways for operators to input instructions to the operating console. For example, they can input instructions directly through the input interface of the operating console, and can also use wireless devices to remotely control the operating console.
在破拆机器人的作业过程中,作业装置2的负荷经常会发生波动,短时间的、偶然的负荷变化通常不会带来整机发热量的明显变化,从节约控制资源、提高响应性的角度出发,这种情况下可以不对散热装置的功率进行调节,因此,有必要区分暂时性的负荷变化和持续性的负荷变化情况下的热量管理方法。During the operation of the demolition robot, the load of the working device 2 often fluctuates. Short-term, accidental load changes usually do not bring significant changes in the heat generated by the entire machine. From the perspective of saving control resources and improving responsiveness, Starting from this situation, the power of the heat sink does not need to be adjusted. Therefore, it is necessary to distinguish between thermal management methods under temporary load changes and persistent load changes.
因此,在一些实施例中,破拆机器人还包括与控制装置信号连接的压力传感器,压力传感器被配置为在作业装置2的负荷持续增加的情况下检测液压系统的液压管路的压力变化并反馈至控制装置,控制装置被配置为在液压管路的压力持续增加的情况下增大散热装置的散热功率。Therefore, in some embodiments, the demolition robot further includes a pressure sensor connected with a signal to the control device. The pressure sensor is configured to detect pressure changes in the hydraulic pipeline of the hydraulic system and provide feedback when the load of the working device 2 continues to increase. To the control device, the control device is configured to increase the heat dissipation power of the heat dissipation device when the pressure of the hydraulic pipeline continues to increase.

在本发明中,将预先型的热管理模式作为主要的热管理方法,并且可将上述实施例中的温度发生变化后再进行的散热功率调控作为辅助的热管理方法,两种热管理方法实现相互协同,进一步提高破拆机器人热管理的可靠性和高效性。In the present invention, the pre-type thermal management mode is used as the main thermal management method, and the heat dissipation power regulation after the temperature changes in the above embodiment can be used as the auxiliary thermal management method. The two thermal management methods are implemented Collaborate with each other to further improve the reliability and efficiency of thermal management of the demolition robot.

参考图3所示,在一些实施例中,破拆机器人还包括回转平台6,液压系统和发动机3均安装于回转平台6上,散热装置安装于发动机3上。Referring to FIG. 3 , in some embodiments, the demolition robot also includes a rotary platform 6 , the hydraulic system and the engine 3 are both installed on the rotary platform 6 , and the heat dissipation device is installed on the engine 3 .

在上述实施例中,换向器9起到发动机3和液压泵1之间的动力传动作用,换向器9的传动比可根据需要进行设置,例如可设置为1:1、1:2、2:1等。相比于将发动机3和液压泵1直接连接(即发动机3的输出轴和液压泵1的输入轴对齐连接)的布置方式,通过将发动机3和液压泵1采用输出轴和输入轴的轴线垂直布置并通过换向器9进行连接,能有效减小发动机3和液压泵1的总装配长度,能够进一步节约破拆机器人水平方向上的安装空间,有助于实现破拆机器人中各部件的紧密布置,从而减小其整体体积。In the above embodiment, the commutator 9 plays the role of power transmission between the engine 3 and the hydraulic pump 1. The transmission ratio of the commutator 9 can be set as needed, for example, it can be set to 1:1, 1:2, 2:1 etc. Compared with the arrangement of directly connecting the engine 3 and the hydraulic pump 1 (that is, the output shaft of the engine 3 and the input shaft of the hydraulic pump 1 are aligned and connected), by arranging the engine 3 and the hydraulic pump 1 with the axes of the output shaft and the input shaft perpendicular Arrangement and connection through the commutator 9 can effectively reduce the total assembly length of the engine 3 and the hydraulic pump 1, further save the installation space in the horizontal direction of the demolition robot, and help achieve the close integration of various components in the demolition robot. arranged to reduce its overall size.

Correspondingly, the commutator 9 can be replaced by a universal transmission device or the like.
作业装置2通常包括用于进行抓取、搬运、破碎等作业的机具结构,例如机械臂、挖斗、破碎锤等,通常体积和质量都比较大,加上作业装置2需要经常进行移动,容易导致破拆机器人重心不稳,发生晃动,进而带来安全隐患。为了解决上述问题,可以采用给作业装置2设置配重的方法,但增加的配重不仅会使破拆机器人的体积变大,对破拆机器人的可作业环境带来限制,还会使破拆机器人的重量显著提升,从而增加其运行的能量损耗。The working device 2 usually includes a machine tool structure used for grabbing, transporting, crushing and other operations, such as a mechanical arm, a bucket, a breaker, etc. The volume and mass of the working device 2 are usually relatively large. In addition, the working device 2 needs to be moved frequently and is easy to move. As a result, the center of gravity of the demolition robot is unstable and shakes, which in turn creates potential safety hazards. In order to solve the above problem, a counterweight can be provided for the working device 2. However, the added counterweight will not only increase the size of the demolition robot, but also restrict the working environment of the demolition robot. The weight of the robot increases significantly, thereby increasing the energy consumption of its operation.
