After the expansion bolt is hammered in place, the hammering assembly 134 stops hammering, but the first jacking member 136 ensures that the tightening assembly 135 is jacked up, and then the rotary driving member 133 drives the sleeve member 1351 to rotate, so as to drive the nut of the expansion bolt to rotate, and further tighten the nut. The first jacking member 136 stops jacking the tightening assembly 135 and lowers to the home position so that the sleeve 1351 is disengaged from the expansion bolt and the rotary drive 133 drives the sleeve 1351 to reverse to the initial position at which time the expansion bolt installation apparatus completes the expansion bolt installation and is ready for the next expansion bolt installation.

Further, referring to fig. 3 and 11, the tightening assembly 135 further includes a mounting seat 1353, and the mounting seat 1353 rotatably mounts the sleeve 1351 thereon.

Thus, the installation of the suspender 80 can be prevented from being damaged due to the overlarge hammering stroke, and meanwhile, the instable installation of the suspender 80 due to the overlarge hammering stroke can also be prevented.

Optionally, the first limit switch 137 and the second limit switch 138 are both electromagnetic limit switches, and the first magnetic ring and the second magnetic ring are respectively disposed at the upper limit position and the lower limit position. When the top piece 1343 reaches the upper limit position, the first limit switch 137 detects the first magnetic ring, thereby controlling the hammering driving piece 1341 to stop jacking. When the top piece 1343 reaches the lower limit position, the second limit switch 138 detects the second magnetic ring, thereby controlling the hammering driving piece 1341 to stop descending.

Further, referring to fig. 3, the hole drilling mechanism 131 includes a power drill and a second lifting member for driving the power drill to move up and down, and the second lifting member is used for driving the power drill to move in a direction close to or far away from the working surface 90.

In one embodiment, the cross member 11 is fixed with the support frame 12 arranged along the second direction, and the support frame 12 is provided with the tightening portion 125. Thus, when the boom 80 needs to be punched and installed, the installation executing device 10 is driven to move along the direction close to the working surface 90 until the tight supporting part 125 supports against the working surface 90, the fixed cross beam 11 is used, the first boom installation head and the second boom installation head are prevented from shaking in the punching and installation process of the boom 80, and the operation stability is improved.

Wherein the first direction is perpendicular to the second direction. In the present embodiment, the second direction is denoted by L2.

Further, the tightening portion 125 is provided with an anti-slip structure for tightening the work surface 90. So, after the installation position had been confirmed, continue jacking installation executing device 10, make the tight working face 90 in anti-skidding structure top, increase the frictional force between tight portion 125 in top and the working face 90, effectively avoid first jib installation aircraft nose and second jib installation aircraft nose to rock at the in-process of punching and installation jib 80, improve job stabilization nature.

Optionally, the non-slip feature is a serration. Of course, in other embodiments, the anti-slip structure may also be an anti-slip pattern, an anti-slip bump, etc., which is not limited thereto.

Referring to fig. 3, 4 and 10, when the mounting actuator 10 is in a free state during operation, a certain amount of shaking inevitably occurs, which results in poor positioning accuracy, and therefore, the mounting actuator 10 is usually required to be tightly pressed against the operation surface 90 during operation. However, when the working surface 90 is pressed tightly, the actuator needs to be mounted to adjust the position and posture against a large frictional force, and the working surface 90 may be damaged during the adjustment. In view of the above problem, in the present embodiment, the supporting frame 12 is provided with a supporting portion 126 lower than the tightening portion, the supporting portion 126 is connected with a second elastic member 121 arranged along the second direction, and the other end of the second elastic member 121 far from the supporting portion 126 is connected with a rolling member 122. The rolling member 122 includes a first state in which the top of the rolling member 122 is higher than the abutting portion 125, so that the rolling member 122 is pressed against the work surface 90 by the compressive force of the second resilient member 121, and a second state. In the second state, the top of the roller 122 is not higher than the abutting portion 125, and the abutting portion 125 abuts against the work surface 90. During operation, the rough position of the boom 80 to be installed is found by observing whether the projection line 23 and the reference line 24 coincide with each other, and then the installation actuator 10 performs an ascending motion so that the spherical surface of the rolling member 122 stops ascending after contacting the operation surface 90. Then, the revolving mechanism 30 drives the beam 11 to rotate, and the second traversing mechanism 16 drives the beam 11 to move along the first direction until the projection line 23 coincides with the reference line 24. In this process, the second elastic element 121 is in a compressed state, and the compression force of the second elastic element 121 enables the installation and execution device 10 to have a certain pre-tightening force on the operation surface 90, so that the rolling element 122 slightly abuts against the operation surface 90, and the installation and execution device 10 is prevented from shaking during the operation. Meanwhile, the surface of the rolling member 122 is smooth and can rotate freely, so that the friction force received by the installation executing device 10 in the adjusting process is small, the adjustment of the position and the posture is convenient, and the damage to the working surface 90 can be avoided. After the posture and position adjustment is completed, the installation executing device 10 continues to ascend until the tightening part 125 tightly pushes against the working surface 90, and the installation executing device 10 stops ascending, and completely pushes against the working surface 90 through the tightening part 125, so that the installation executing device 10 is effectively prevented from shaking in the processes of punching and installing the suspender 80, the working counter force is overcome, and the stability of the installation executing device 10 during operation is ensured.

Therefore, by arranging the second guide post 123, the compression process of the second elastic member 121 has guidance, and instability phenomena such as shaking and the like of the second elastic member 121 in the compression process are avoided. In this embodiment, the outer surface of the second guide post 123 is provided with a threaded section.

During operation, when the lifting mechanism 50 sends the installation executing device 10 to a position close to the operation surface 90, the rolling member 122 contacts the operation surface 90 first, the lifting mechanism 50 continues to lift, and the rolling member 122 moves downward after receiving pressure and drives the limit switch 124 to move downward. When the limit switch 124 moves to the first position, the lifting mechanism 50 stops lifting, at this time, the top of the rolling member 122 is still higher than the jacking portion 125, and the second elastic member 121 is in a compressed state, so that the installation executing device 10 has a certain pre-tightening force on the working surface 90, the installation executing device 10 is prevented from shaking, and the installation executing device 10 is easy to adjust the position and the posture.
