Sand box body for unloading steel structure net and truss
The invention discloses a sand box body for unloading a steel structure net and a truss. The sand box body comprises an outer cylinder and an inner cylinder slidably sleeved in the inner cavity of the outer cylinder, the bottom end of the outer cylinder is fixedly connected with a lower supporting plate, the top end of the inner cylinder is fixedly connected with an upper supporting plate, a horizontal displacement assembly is arranged at the top end of the upper supporting plate, and a flow guide hopper is sleeved with the bottom of the inner cavity of the outer cylinder; a dry sand assembly matched with the flow guide hopper and the inner cylinder is contained in the inner cavity of the outer cylinder, the bottom end of the flow guide hopper is in through connection with a sand discharging pipe, one side end of the sand discharging pipe is in through connection with a side flow hole, the inner cavity of the sand discharging pipe is rotationally connected with a control shaft, and a communicating hole is embedded in the top end of the control shaft; according to unloading in the whole vertical direction, the control shaft can be indirectly driven to rotate by continuously rotating a handle, so that a sand outlet hole and a side flow hole are periodically communicated, the dry sand assembly is periodically discharged, the discharging speed and the discharging amount of the dry sand assembly are controlled, the descending displacement of the inner cylinder is controlled according to the sand discharging speed and the sand discharging amount, and accurate unloading is realized.
本发明公开了一种钢结构网、桁架卸荷用砂箱体，包括外筒和滑动内套在外筒内腔中的内筒，外筒的底端固定连接下撑板，内筒的顶端固定连接上撑板，上撑板的顶端设有水平位移组件，外筒的内腔底部内套设有导流斗，外筒的内腔盛放有与导流斗和内筒相配合的干砂组件，导流斗的底端贯通连接排沙管，排沙管的一侧端贯通连接侧流孔，排沙管的内腔转动连接控制轴，控制轴的顶端嵌设有连通孔；本发明的整个垂直方向上的卸载，可以通过不断的转动手柄，进而间接的带动控制轴转动，使得出沙孔与侧流孔之间周期性的连通，从而周期性的排出干砂组件，进而控制干砂组件的排出速度和排出量，最终以出砂速度和出砂量来控制内筒下降位移，从而实现精确卸载。
