需要说明的是， 在不沖突的情况下， 本申请中的实施例及实施例 中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本 发明。 It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The invention will be described in detail below with reference to the drawings in conjunction with the embodiments.
参见图 1 , 示出了根据本发明的一种平衡装置的原理流程图， 如 图所示， 该平衡装置包括： 移动配重装置 4,设置在起重机的车体上， 具有活动设置的移动配重块 41; 驱动机构 3, 与移动配重块 41驱动 连接； 感应装置 1 , 例如感应装置 1为水平角度感应器， 可以感应起 重机的倾斜角度； 控制器 2, 与感应装置信号连接， 接收感应装置 1 发出的倾斜角度信号后判断出起重机的倾斜方向并向驱动机构 3 发 出控制信号， 以控制驱动机构 3动作， 使驱动机构 3驱动移动配重块 41向相反于起重机的倾斜方向的方向移动。 Referring to Figure 1, there is shown a schematic flow diagram of a balancing device according to the present invention. As shown, the balancing device comprises: a mobile counterweight device 4, disposed on the body of the crane, having an active setting of the mobile device. The driving mechanism 3 is drivingly connected with the moving weight 41; the sensing device 1 , for example, the sensing device 1 is a horizontal angle sensor, can sense the tilt angle of the crane; the controller 2 is connected with the sensing device signal, receiving the sensing After the tilt angle signal from the device 1, the tilt direction of the crane is determined and a control signal is sent to the drive mechanism 3 to control the operation of the drive mechanism 3 to cause the drive mechanism 3 to drive the moving weight 41 to move in a direction opposite to the tilt direction of the crane. .
参见图 2和图 3, 示出了根据本发明的平衡装置应用于起重机的 第一实施例的结构， 在该实施例中， 移动配重装置 4包括： 导轨 42 和与导轨 42相配合的移动配重块 41 , 移动配重块 41具有与导轨 42 相配合的凹槽结构。 例如导轨 42设置在安装平台 （回转台 ) 5 上以 便于安装， 其延伸方向垂直于起重机的行驶方向， 使得移动配重块 41 的移动方向同样垂直于起重机行驶方向。 因为起重机发生侧翻的 可能性比较大， 因此只要使移动配重块 41可沿与起重机行驶方向垂 直的方向移动即可， 这样当控制器 2判断出车体朝一侧发生倾斜时， 移动配重块 41在执行结构 3的作用下朝起重机车体倾斜方向相反的 方向移动， 以使移动配重块 41对车体产生与其倾斜方向相反的力， 使起重机保持平衡， 不容易发生侧翻。优选地水平角度感应器 1设置
在安装平台 5上并与导轨 42平行， 以便于准确感应起重机的倾斜角 度。 Referring to Figures 2 and 3, there is shown a structure of a first embodiment of a balancing apparatus according to the present invention applied to a crane, in which the moving weight apparatus 4 comprises: a guide rail 42 and a movement cooperating with the guide rail 42 The weight 41 and the moving weight 41 have a groove structure that cooperates with the guide rail 42. For example, the guide rail 42 is arranged on the mounting platform (rotary table) 5 for installation, and its extension direction is perpendicular to the traveling direction of the crane, so that the moving direction of the moving weight 41 is also perpendicular to the traveling direction of the crane. Since the possibility of the rollover of the crane is relatively large, the moving weight 41 can be moved in a direction perpendicular to the traveling direction of the crane, so that when the controller 2 determines that the vehicle body is tilted toward one side, the weight is moved. The block 41 is moved in the opposite direction to the tilt direction of the crane body by the execution structure 3, so that the moving weight 41 generates a force opposite to the tilt direction of the vehicle body, so that the crane is balanced and the rollover is less likely to occur. Preferably the horizontal angle sensor 1 is set It is mounted on the mounting platform 5 and parallel to the guide rails 42 to facilitate accurate sensing of the tilt angle of the crane.
驱动机构 3进一步地为带有伺服阀的液压油缸， 设置在导轨 42 的至少一侧之外的固定支点上，例如液压油缸 3的缸体端固定在上述 固定支点上， 液压油缸的活塞杆外端与移动配重块 41连接。 液压油 缸 3根据控制器 2发出的控制信号，其无杆腔和有杆腔处于相反的进 出油状态， 促使其活塞杆做相应的伸缩动作， 从而带动移动配重块 41移动， 这种控制方式结构筒单， 方便有效。 当然， 如图 2中所示 出的， 可以在导轨 42的两侧外部都设置液压油缸 3 , 两个液压油缸 3 的活塞杆外端分别连接移动配重块 41 , 从而使得移动配重块 41的移 动更加顺畅可靠， 而且当其中一个液压油缸失效时， 另一个液压油缸 还可以有效控制移动配重块 41的移动，保证了平衡装置的运行可靠。 The driving mechanism 3 is further a hydraulic cylinder with a servo valve disposed on a fixed fulcrum other than at least one side of the guide rail 42. For example, the cylinder end of the hydraulic cylinder 3 is fixed on the fixed fulcrum, and the hydraulic cylinder is outside the piston rod. The end is connected to the mobile weight 41. The hydraulic cylinder 3 is in accordance with the control signal from the controller 2, and the rodless chamber and the rod chamber are in opposite oil inlet and outlet states, causing the piston rod to perform corresponding telescopic movement, thereby driving the moving weight 41 to move. The structure is simple and convenient. Of course, as shown in FIG. 2, hydraulic cylinders 3 may be disposed on both sides of the guide rails 42, and the outer ends of the piston rods of the two hydraulic cylinders 3 are respectively connected to the moving weights 41, thereby moving the weights 41. The movement is smoother and more reliable, and when one of the hydraulic cylinders fails, the other hydraulic cylinder can also effectively control the movement of the moving weight 41, ensuring reliable operation of the balancing device.
优选地， 为增加移动配重块的安全性能， 在导轨的两端还设置有 止挡防护结构 6, 例如为设置在导轨 42两端的止挡板 6以防止因移 动配重块 41的意外滑出引发的安全事故。 止挡板只要达到使导轨其 与移动配重块相配合的凹槽两端密封即可， 或者如图中所示， 止挡板 的高度较高， 还可以对移动配重块 41的整体进行止挡。 Preferably, in order to increase the safety performance of the mobile weight, a stop guard structure 6 is provided at both ends of the guide rail, for example, a stop plate 6 disposed at both ends of the guide rail 42 to prevent accidental slippage due to the moving weight 41 A safety incident has arisen. The stop plate may be sealed as long as the groove of the guide rail is matched with the moving weight, or as shown in the figure, the height of the stop plate is high, and the whole of the moving weight 41 can be performed. Stop.

优选地， 液压油缸 3平行设置在导轨 42的外侧， 并通过横向连 接结构连接移动配重装置 4, 由于液压油缸 3并未设置在移动配重装 置 4的运动轨道上， 因此， 不会影响移动配重装置 4的运动， 同时能 够增大其运动行程， 扩大其调节范围。 Preferably, the hydraulic cylinders 3 are disposed in parallel on the outer side of the guide rails 42 and are connected to the mobile counterweight device 4 by a lateral connection structure. Since the hydraulic cylinders 3 are not disposed on the moving track of the moving counterweight device 4, the movement is not affected. The movement of the weight device 4 can simultaneously increase its movement stroke and expand its adjustment range.
