Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a pushing and buffering device for comprehensive pipe gallery construction comprises a buffering cylinder body 4, wherein the buffering cylinder body 4 is of a cylindrical cylinder body structure, a spring 2 is connected inside a groove of the buffering cylinder body 4, a buffering layer plate 5 is connected to the outside of the bottom end of the buffering cylinder body 4, and a support fixing bottom plate 6 is installed at the outside of the bottom end of the buffering layer plate 5, the buffering layer plate 5 and the support fixing bottom plate 6 are sequentially installed below the buffering cylinder body 4 through the structure, the buffering layer plate 5 and the support fixing bottom plate 6 are of cylindrical structures, the diameter of the support fixing bottom plate 6 is equal to that of a buffering top cover 1, the side edge of the support fixing bottom plate 6 cannot protrude out of the side wall of the buffering top cover 1 through the structure; the diameter of the buffer layer plate 5 is equal to that of the buffer cylinder body 4, the buffer layer plate 5 is of a honeycomb structure, the structure enables the pressure on the buffer cylinder body 4 to be transmitted to the buffer layer plate 5 completely, the buffer layer plate 5 of the multi-layer honeycomb structure can consume the pressure transmitted by the buffer cylinder body 4, and therefore the effect of buffering pressure is achieved, a support fixing hole 7 is formed in the support fixing bottom plate 6, the support fixing hole 7 is of a through hole structure, and a user can insert a bolt into the support fixing hole 7 of the through hole structure to be inserted into the pushing support to fix the support fixing bottom plate 6 and the pushing support together; the top end of the spring 2 is connected with a buffering top cover 1, the buffering top cover 1 is of an inverted cylindrical barrel structure, the diameter of an inner hole of the buffering top cover 1 is equal to the diameter of the outer wall of the buffering barrel 4, when the spring 2 is in a free state, the height of the bottom end of the buffering top cover 1 is lower than that of the top end of the buffering barrel 4, the bottom end of the buffering top cover 1 is higher than the bottom end of the buffering cylinder 4, the top end of the buffering top cover 1 is internally provided with a pushing jack fixing hole 3, the structure ensures that the jack can be arranged on the buffering top cover 1 through the pushing jack fixing hole 3, so that the device can be positioned between the jack and the pushing support, the pressure exerted by the jack on the buffer cap 1 causes the compression of the spring 2, the compression of the spring 2 generates a reaction force towards the jack, thereby consuming the pressure of the jack and playing a role of buffering the pressure applied by the jack towards the direction of the pushing support; the number of the jacking jack fixing holes 3 is at least 4, the axial lines of the jacking jack fixing holes 3 are parallel to the axial line of the buffering top cover 1, the jacking jack can be vertically arranged on the buffering top cover 1 through the jacking jack fixing holes 3, and the axial line dislocation between the jacking jack and the buffering top cover 1 cannot occur.
