DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-6 The utility model provides a technical solution: a roadbed compression test striker that can be stably installed, including a base 1, a striking platform 2, a fixed bracket 3, a fixing mechanism 4, a connecting bolt 5, a connecting rod 6, a fixing block 7, a fixed splint 8, a protective cover 9, a connecting plate 10, a connecting column 11, a spring 12, a movable plate 13, an auxiliary plate 14, a fixing pin 15, an electric telescopic rod 16, a moving plate 17, a moving bracket 18 and a striking hammer 19.

[0032] When using the roadbed compression tester that can be stably installed, Figure 1 and Figure 2 As shown, a striking platform 2 is fixedly installed on the upper end of the base 1. First, the roadbed block to be tested is directly placed on the upper end of the striking platform 2, and the fixing mechanism 4 is symmetrically arranged on the left and right ends of the striking platform 2. The fixing mechanism 4 includes a connecting bolt 5 for adjustment, a connecting rod 6 for connection, a fixing block 7 fixedly connected to the left and right sides of the upper end of the striking platform 2, and a fixing clamping plate 8 for clamping. By rotating the connecting bolt 5 threadedly connected to the striking platform 2, the connecting bolt 5 and the connecting rod 6 are rotated, and the connecting bolt 5 drives the connecting rod 6 and the fixing block 7 to slide, so that the connecting rod 6 drives the fixing clamping plate 8 to extend and retract at the upper end of the striking platform 2, thereby driving the fixing clamping plate 8 to stably clamp the roadbed block at the upper end of the striking platform 2 to prevent the roadbed block from shifting during the test.

[0033] After clamping is completed, Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, by pulling the movable plate 13, the movable plate 13 slides with the auxiliary plate 14, and the movable plate 13 slides with the connecting column 11, the movable plate 13 squeezes the spring 12, so that the spring 12 is elastically deformed, and the movable plate 13 drives the fixing pin 15 to extend and retract, so that the fixing pin 15 is disengaged from the fixing bracket 3, thereby releasing the limit between the connecting plate 10 and the fixing bracket 3, and then pulling the connecting plate 10 downward, the connecting plate 10 slides with the fixing bracket 3, driving the protective cover 9 to rise and fall at the upper end of the base 1, so that the protective cover 9 moves downward and is arranged on the outer side of the striking platform 2, and then directly releasing the movable plate 13, at this time the spring 12 restores the elastic deformation, drives the movable plate 13 to slide with the connecting column 11, so that the movable plate 13 drives the fixing pin 15 to engage with the corresponding position of the lower end of the fixing bracket 3, thereby facilitating the limit between the connecting plate 10 and the fixing bracket 3, and fixing the protective cover 9;

[0034] After the fixation is completed, Figure 1 and Figure 6 As shown, the electric telescopic rod 16 installed on the upper end of the fixed bracket 3 is directly started, and the electric telescopic rod 16 drives the movable plate 17 to slide with the fixed bracket 3, so that the movable plate 17 drives the movable bracket 18 to separate from the striking hammer 19. At this time, the striking hammer 19 performs free fall downward under the action of gravity, and the striking hammer 19 performs a striking test on the roadbed block on the striking platform 2, which is very convenient to use.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
