Detailed Description
Specific embodiments of the present invention are further described below in conjunction with the appended drawings, but the scope of the claims is not limited thereto.
As shown in fig. 1-2, the tool for conveniently installing and removing a manhole door cover plate at the bottom of a large-scale device provided by the utility model comprises a connecting rod 1, a stress plate 2, a nut 3, a metal rod 4 and an extension screw 5, wherein the nut 3 is sleeved on the metal rod 1 through threads, the stress plate 2 is arranged at the top of the nut 3, the stress plate 2 is a multilayer elastic metal sheet, the diameter of the elastic metal sheet is gradually increased from bottom to top, a boss is arranged at the top of the metal rod 4, grooves are arranged at the bottoms of the metal rod 4 and the connecting rod 1, threads which are matched with each other are respectively arranged on the inner wall of each groove and the outer wall of each boss, the connecting rod 1 is fixed at the top of the metal rod 4 through threads, and a plurality of extension screws 5 which have the same structure as the metal rod are additionally arranged at the bottom of the metal rod 4.
The outer wall of the connecting rod 1 is connected with a manhole door threaded hole at the bottom of the large-scale equipment 6 through threads on the outer wall of the connecting rod, so that the stress plate 2 at the top of the screw cap 3 provides stress points for a manhole door cover plate 7; the nut 3 can still move under the stress condition through the stress plate 2; the length of the tool is controlled by prolonging the number of the screw rods 5 to adapt to different working environments.
In another embodiment of the utility model, the stress plate 2 supports the manhole door cover plate 7 by filling a spring between two support plates.
In another embodiment of the present invention, the force-bearing plate 2 is made of rubber.
Above-mentioned instrument convenient to installation and demolish large-scale equipment bottom manhole door plant, its work flow is as follows:
with 3 suits of nut on metal pole 4, 3 tops of nut installation atress boards 2 select the connecting rod of different diameters according to the size of the bolt hole on the manhole door, with the bolt hole connection on connecting rod and the manhole door. The boss of the metal rod 4 is fixed through the groove at the bottom of the connecting rod 1, a proper amount of extension screws 5 are installed according to different operating environments, and meanwhile, different numbers of tools are installed according to the size and the weight of the manhole door cover plate, so that the manhole door cover plate has better stability during loading and unloading; during the installation, transferring nut 3 on metal pole 4 to lower same horizontal position, placing manhole door apron 7 on 2 surfaces of atress board, at last with connecting rod 1 and the bolt hole connection on the manhole door, make manhole door apron 7 carry out the removal of vertical direction through rotatory whole nuts simultaneously, carry out the installation of bolt until hugging closely the manhole door, demolish connecting rod 1 at last, finish the installation of remaining bolt hole.
