Detailed Description
The following description of the embodiments of the present utility model will be apparent from, and is intended to provide a thorough description of, the embodiments of the present utility model, and not a complete description of, the embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, are intended to fall within the scope of the present utility model.
Examples
Referring to fig. 1-5, a double-wall steel cofferdam sinking guide apparatus, comprising:
a cofferdam body 100;
the guide piece 200, the guide piece 200 includes a fixed plate 201, a connecting rod 202, a guide plate 203, a connecting cylinder 204 and a connecting bolt 205, the fixed plate 201 is connected to the cofferdam body 100, and the fixed plate 201 can move horizontally along the cofferdam body 100; the connecting rod 202 is welded in the middle of the outer wall of the fixed plate 201, and a thread groove 2021 is formed in the top surface of the connecting rod 202; the cross section of the guide plate 203 is an arc-shaped cross section matched with the side wall of the steel casing, and when the steel casing is used, lubricating oil is smeared on the side wall of the guide plate 203 corresponding to the steel casing so as to reduce friction; one end of the connecting tube 204 is sleeved on the connecting rod 202, one end of the connecting tube 204 is welded at the middle part of one side of the guide plate 203, which is close to the fixed plate 201, and an adjusting groove 2041 corresponding to the thread groove 2021 is formed in the top surface of the connecting tube 204; the inner end of the connecting bolt 205 penetrates through the adjusting groove 2041 and is connected in the thread groove 2021 in a threaded manner; when the connecting bolt 205 is screwed, the outer tip of the connecting bolt 205 is closely abutted against the outer wall of the connecting cylinder 204.
In this embodiment, the specific connection manner between the fixing plate 201 and the cofferdam body 100 is as follows: the fixing plate 201 is provided with 2 waist-shaped holes 2011 at intervals up and down; the connecting rod 202 is positioned in the middle of the 2 waist-shaped holes 2011; the cofferdam body 100 is provided with a fixing bolt 101 corresponding to the waist-shaped hole 2011, and the fixing bolt 101 penetrates through the waist-shaped hole 2011 and is connected with a fixing nut 102 in a threaded manner. More specifically, each of the waist-shaped holes 2011 corresponds to 2 fixing bolts 101, and the interval between the 2 fixing bolts 101 is smaller than the length of the waist-shaped hole 2011.
In addition, in the present embodiment, 2 guide rods 206 are symmetrically welded to both sides of the connection rod 202; two sides of the connecting tube 204 are correspondingly welded with 2 guide tubes 207 which are in sliding guide fit with the guide rods 206, and cross sections of the connecting rod 202, the connecting tube 204, the guide rods 206 and the guide tubes 207 are rectangular.
