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.

[0030] See also Figure 1-5 The utility model provides a technical solution: a tunnel detection knocker that is easy to move, including a base 1, a moving wheel 2, a fixed column 3, a connecting mechanism 4, a mounting plate 5, a connecting column 6, a connecting bracket 7, a connecting rod 8, a fixing bolt 9, a fixing cap 10, a mounting bracket 11, an electric telescopic rod 12, a knocking hammer 13, a spring 14, a movable plate 15, a fixing block 16, a fixing pin 17 and a fixing groove 18.

[0031] When using this portable tunnel inspection tapper, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, first, the knocker is moved to the corresponding position in the tunnel by the moving wheel 2, and the connecting mechanism 4 is arranged above the base 1, and the connecting mechanism 4 includes a mounting plate 5 for support, a connecting column 6 inserted in the middle of the mounting plate 5, a connecting bracket 7 fixedly connected to the left and right ends of the mounting plate 5, and a connecting rod 8 inserted in the middle of the connecting bracket 7. First, by pulling the movable plate 15, the movable plate 15 slides with the fixed block 16, and the movable plate 15 squeezes the spring 14, so that the spring 14 is elastically deformed, and at this time the movable plate 15 drives the fixing pin 17 is extended and retracted, so that the fixing pin 17 is moved out of the fixing groove 18, thereby releasing the limit between the mounting plate 5 and the fixing column 3, and then the mounting plate 5 is pulled upward, and the mounting plate 5 and the fixing column 3 slide, so that the mounting plate 5 drives the side percussion hammer 13 to move to the corresponding percussion detection position of the tunnel side wall. When reaching the corresponding position, the movable plate 15 is directly released. At this time, the spring 14 restores the elastic deformation, so that the movable plate 15 drives the fixing pin 17 to engage in the fixing groove 18 at the corresponding position, thereby facilitating the limit between the mounting plate 5 and the fixing column 3;

[0032] After the limit is completed, Figure 1 and Figure 3As shown, by pulling the connecting column 6 up and down, the connecting column 6 slides in the middle of the mounting plate 5, so that the connecting column 6 drives the upper knocking hammer 13 to move, and moves the upper knocking hammer 13 to the knocking position away from the top of the tunnel, and then by rotating the fixing cap 10 threadedly connected to the outer surface of the connecting column 6, the fixing cap 10 is fitted at the upper and lower ends of the middle of the mounting plate 5, so as to facilitate the limiting of the mounting plate 5 and the connecting column 6. After the limiting is completed, by pulling the connecting rod 8, the connecting rod 8 and the connecting bracket 7 slide, so that the connecting rod 8 drives the side knocking hammer 13 to move telescopically, and drives the side knocking hammer 13 to move to the corresponding knocking position on the side of the tunnel, and then by rotating the fixing bolt 9, the fixing bolt 9 and the connecting rod 8 as well as the fixing bolt 9 and the connecting bracket 7 are all threadedly connected, and the fixing bolt 9 is used to limit the connection between the connecting rod 8 and the connecting bracket 7, so as to complete the position adjustment of the knocking hammer 13;

[0033] After the adjustment is completed, the fixed column 3 is pushed so that the base 1 drives the moving wheel 2 to roll on the ground, so as to drive the entire equipment to move in the tunnel. At the same time, the electric telescopic rod 12 installed in the middle of the mounting bracket 11 is started. The electric telescopic rod 12 is powered by a battery. The electric telescopic rod 12 drives the percussion hammer 13 to knock on the tunnel. The percussion hammer 13 is provided with multiple groups, so that the top and side walls of the tunnel can be synchronously detected and knocked at the same time, and the force of knocking on the top and side walls of the tunnel can be kept the same, which is very convenient to use.
