[0018] With reference to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the utility model relates to a tunnel roof danger elimination device, which comprises a lifting rod 1, an assembly sleeve 3 and a danger elimination unit 2.

[0019] The lifting rod 1 is the assembly base of the device, and the assembly sleeve 3 is hingedly arranged on the lifting rod 1.

[0020] The danger elimination unit 2 is fixedly arranged in the assembly sleeve 3.

[0021] The angle adjustment long rod 31 is also fixedly arranged on the assembly sleeve 3.

[0022] The effect achieved is that the lifting rod 1 can lift or lower the assembly sleeve 3 and the assembly body of the pressure rod upwards to adjust the height of the tunnel roof; the angle adjustment long rod 31 can adjust the orientation angle of the danger elimination unit 2, that is, the device points to the target position, drives the danger elimination unit 2 to act on the target area, and thus the danger elimination action can be realized.

[0023] In embodiment 1, the lifting rod 1 is one of a single hydraulic prop or an electric push rod.

[0024] A holding handle 11 is fixedly arranged on the core barrel of the single hydraulic prop or electric push rod.

[0025] The effect achieved thereby is that the device is held and positioned.

[0026] Further, the risk removing unit 2 is a wind gun or a breaking hammer.

[0027] The effect achieved thereby is that, based on embodiment 1, the action of the steel drill 22 is simulated by using the wind gun or the breaking hammer, and a labor-saving risk removing action is achieved.

[0028] In embodiment 2, the risk removing unit 2 comprises an action unit 21 and a steel drill 22, the action unit 21 is one of a hydraulic cylinder, an air cylinder or an electric push rod, and the steel drill 22 is fixedly arranged on the piston of the action unit 21.

[0029] Further, the lifting rod 1 is fixedly arranged on a walking trolley.

[0030] The effect achieved thereby is that, based on embodiment 2, in cooperation with the self-weight of the walking trolley, a hammering action different from the wind gun or the breaking hammer in the prior art is achieved by using the push rod type device, that is, the steel drill 22 is used to apply pressure to the target area to destroy the weak connection position, so as to achieve a safer risk removing purpose.
