The utility model discloses a double-cylinder hydraulic force measuring device, which comprises a device body including a hydraulic control and oil supply system, an electronic control system, two sets of hydraulic cylinders, a hydraulic cylinder stretching device and a hydraulic cylinder fixing device. The fixing device of the hydraulic cylinder is connected with the pre-buried ground anchor by bolts. One end of the two groups of hydraulic cylinders is connected with the fixing device of the hydraulic cylinder by screws. The other end of the two groups of hydraulic cylinders is connected with the drawing plate of the hydraulic cylinder drawing device. The drawing plate of the hydraulic cylinder drawing device is provided with a ball hinge connecting device. The hydraulic control and fuel supply system is connected with the electric control system. The oil supply system adopts high and low hydraulic pumps to supply oil and keep pressure. The utility model is equipped with two sets of hydraulic cylinders, which can effectively test the load of the crane with large tonnage; the drawing plate of the hydraulic cylinder drawing device is equipped with a ball hinge connecting device, which compensates for the situation that the lifting point of the crane and the lifting point of the device are not in the same line or the position deviation of the hook occurs in operation, and avoids the generation of lateral pulling force.

一种双缸液压式测力装置
本技术涉及测力设备
,具体地说,是涉及一种双缸液压式测力装置。
技术介绍
目前测力装置有很多,例如弹簧秤、台秤等,然而这些普通秤只能测较小的力,当所测力较大时,普通秤根本完成不了,这时就需要借助其他辅助设备,通常是借助液压装置,通过将液压缸体内的压强值换算成压力值,间接得到所测作用力大小。现我国起重机生产企业和起重机使用单位绝大多数采用砝码(试重块)的实验方法,但在吨位大、砝码提供困难等一些特殊情况下,砝码(试重块)的试验方法将受限制。因此,在现有技术中,起重机生产企业和起重机使用单位绝大多数采用砝码(试重块)的实验方法,但在吨位大、砝码提供困难等一些特殊情况下,砝码(试重块)的试验方法将受限制等问题,设计一种双缸液压式测力装置,是目前需要解决的技术问题。
