Furthermore, each damping unit comprises two connecting lug plates and a connecting clamping plate, and the two connecting lug plates are connected and combined through an overlapping part to form the damping unit.
Further, the damping device arranges a corresponding number of damping units on the operable surface of the temporary rod piece according to actual calculation and operability.
Further, the connecting lug plate is fixedly connected with the temporary rod piece through a welding seam.
Furthermore, the connecting lug plate and the connecting clamp plate are fixed through high-strength bolts, transverse long round holes are formed in the connecting lug plate, vertical long round holes are formed in the connecting clamp plate, and the high-strength bolts penetrate through the transverse long round holes and the vertical long round holes which are mutually crossed and perpendicular to each other and then are fastened.
A second object of the present invention is to provide a method for slowly releasing internal force by the damping device, comprising the steps of:
when the temporary rod piece is unloaded, the temporary rod piece is firstly cut off from the middle, then the bolts on the damping device are loosened slowly one by one, the effect of slowly releasing the internal force is achieved through the sliding of the bolts in the long round holes, when the bolts do not slide relative to the connecting clamping plates, the state of completely releasing the internal force is achieved, and finally the two ends of the temporary rod piece are cut to finish the dismantling operation.
The principle of the invention is as follows: after the middle part of the temporary rod piece is cut, the internal force of the temporary rod piece is transferred to the damping unit, the internal force of the damping unit overcomes the friction force between the bolt and the connecting plate to enable the bolt to slide by slowly loosening the bolt on the damping unit, when the bolt does not slide relative to the connecting clamping plate, the state that the internal force is completely released is achieved, the internal force is gradually changed in the process, and the internal force is not suddenly changed, so that the structure can be prevented from generating larger vibration and displacement.
Compared with the prior art, the invention has the following beneficial technical effects:
(1) by the damping device, stress can be slowly released when the temporary rod piece is unloaded, and the unloading process is more stable and safer.
(2) The damping device has simple and portable structure and is convenient for field installation and uninstallation;
(3) the unloading method for slowly releasing the internal force is convenient to operate and high in efficiency;
(4) the unloading process of slowly releasing the internal force is safe and reliable.
