Detailed description of the invention
With specific embodiment, the utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, anchor pole impact test apparatus of the present utility model, including anchor pole tensile impact test unit and impulsive force applying unit, anchor pole tensile impact test unit and impulsive force applying unit are placed on column 12 successively, and anchor pole tensile impact test unit matches with impulsive force applying unit.
Anchor pole tension impact unit includes base 13, the both sides of base 13 are fixed with column 12, the top of column 12 is provided with back timber 1, it is provided with screwed hole 2 in back timber 1 lower surface center, anchor pole 3 is fixed in this screwed hole 2, the bottom of anchor pole 3 is provided with anchor rod pallet board 6, it is fixedly arranged above shock plate 4 at anchor rod pallet board 6, preferably, shock plate 4 is welded on anchor pole 3, shock plate 4 be arranged over impact beam 5, the both sides of impact beam 5 downwardly extend and are connected to impulsive force applying unit, when impulsive force applying unit forces in impact beam 5, impact beam 5 impacts shock plate 4 to stretch anchor pole 3.The lower end of impact beam connects sensor 7, it is preferred that described sensor is tension sensor.
Described impulsive force applying unit includes that beam 11 fixed by hydraulic shock cylinder 10 and impact cylinder, and described hydraulic shock cylinder 10 is fixed on impact cylinder fixes beam 11 center, and impact cylinder is fixed beam 11 and is installed on column 12 and is positioned on the downside of impact beam 5.Liquid presses piston pole 8 upper end of described hydraulic shock cylinder 10 is connected with sensor 7, the lower end of sensor 7 is fixing with liquid presses piston pole 7 to be connected, the upper end of sensor is fixing with the lower end of impact beam 5 to be connected, can be in the way of employing be threaded, by this connection, liquid presses piston pole 8 and impact beam 5 and sensor 7 associated movement.Described hydraulic shock cylinder 10 is connected with outer liquid press by the inlet 9 on cylinder body.
