Description

Technical Field

[0001] The utility model relates to the technical field related to building construction, in particular to a wellhead blocking structure for building construction. Background Art

[0002] During construction, in order to facilitate the connection of water, sewage and heating pipes, a wellhead will be constructed on the ground in advance. At this time, since there is no manhole cover at the wellhead, a blocking structure will be used to temporarily block the wellhead to prevent people from falling. There is currently a construction wellhead blocking structure (application number: 202022033701.9) that can effectively block the existing construction wellhead to prevent water or soil from accumulating in the wellhead and affecting construction.

[0003] The above-mentioned problem is that when plugging the wellhead, steel pipes need to be welded together to complete the plugging. This operation will take a certain amount of time to build at the wellhead. If there are a large number of wellheads to be plugged, the operation is relatively time-consuming, which will affect the progress of the construction. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a wellhead blocking structure for construction.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A wellhead plugging structure for construction includes a shell, which is rotatably connected to a double-headed screw through a bearing, and two groups of rod bodies are threadedly connected on the double-headed screw, and arc plates are fixed to the two groups of rod bodies. A rubber sleeve is fixed to the shell.

[0007] Preferably, the shell is rotatably connected to a cover body via a connecting shaft, a bolt is threadedly connected to the cover body, and the bolt is threadedly connected to the shell.

[0008] Preferably, the lower portion of the shell is in a truncated cone shape.

[0009] Preferably, two sets of handles are fixedly connected to the double-headed screw.

[0010] Preferably, a sliding rod is fixed inside the shell, and the sliding rod is slidably connected to the two groups of rod bodies.

[0011] Preferably, first rubber pads are fixedly connected to both groups of the arc-shaped plates.

[0012] Preferably, a second rubber pad is fixedly connected to the cover body.

[0013] The beneficial effects of the utility model are:

[0014] 1. Through the coordination between the shell, double-headed screw, rod body and curved plate, the bottom of the shell is designed as a truncated cone, so that when the bottom of the shell is placed at the wellhead, wellheads of different sizes can be plugged to a certain extent. At the same time, the double-headed screw is used to drive the rod body to fit the two sets of curved plates with one end and the other end of the inner wall of the wellhead. The shell can be fixed at the wellhead and the wellhead can be plugged. The plugging is relatively convenient, no construction operation is required, time-saving and labor-saving, and when multiple sets of wellheads are plugged, the construction progress will not be affected;

[0015] 2. By cooperating between the set cover body, bolts and shell, the bolts are connected to the shell thread or the thread connection is cancelled, and the cover body can cover or cancel the cover on the top of the shell, which can facilitate the operation of pumping out the accumulated water in the wellhead while sealing the wellhead.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1, reference Figures 1 to 5A wellhead sealing structure for construction includes a shell 1, which is rotatably connected to a double-headed screw 2 through a bearing. The double-headed screw 2 can be rotated at the shell 1, and two groups of rod bodies 3 are threadedly connected to the double-headed screw 2. The double-headed screw 2 can drive the two groups of rod bodies 3 to move outward on both sides respectively. Arc plates 4 are fixedly connected to the two groups of rod bodies 3. A rubber sleeve 7 is fixedly connected to the shell 1. The rubber sleeve 7 is used to seal the joint between the shell 1 and the wellhead to prevent water and the like from entering the wellhead. The rubber sleeve 7 is inserted into the wellhead by driving the shell 1, and the double-headed screw 2 is rotated to fit the two groups of arc plates 4 with one end and the other end of the inner wall of the wellhead respectively. The shell 1 can quickly seal the wellhead, and the sealing operation is relatively convenient and fast.

[0024] In this embodiment, the shell 1 is rotatably connected to a cover body 5 through a connecting shaft, and a bolt 6 is threadedly connected to the cover body 5, and the bolt 6 is threadedly connected to the shell 1, and the bolt 6 is used to fix the cover body 5. When the cover body 5 is rotated to cancel the obstruction of the top of the shell 1, the wellhead can be cleaned with the help of the inside of the shell 1. The lower part of the shell 1 is designed in a truncated cone shape, so that the shell 1 can seal wellheads of different sizes. Two groups of handles 10 are fixedly connected to the double-headed screw 2, and a sliding rod 9 is fixedly connected to the shell 1. The sliding rod 9 is slidably connected to the two groups of rod bodies 3. The two groups of arc plates 4 are fixedly connected with a first rubber pad 8, and the first rubber pad 8 is used to increase the stability of the arc plate 4 fitting the inner wall of the wellhead and increase the sealing stability. The cover body 5 is fixedly connected with a second rubber pad 11, and the second rubber pad 11 is used to seal the joint between the cover body 5 and the shell 1 to prevent water and the like from entering the shell 1.

[0025] The working principle of this embodiment is as follows: when in use, the conical design of the lower part of the shell 1 is inserted into the wellhead. At this time, because the lower part of the shell 1 is a conical design and there is a rubber sleeve 7, the shell 1 can perform blocking operations on wellheads of different sizes. After blocking the wellhead, the handle 10 drives the double-headed screw 2 to rotate, so that the two sets of arc plates 4 can be fitted with one end and the other end of the inner wall of the wellhead. The shell 1 will be fixed at the wellhead and the wellhead will be blocked. When it is necessary to observe the wellhead, the bolt 6 is removed from the thread of the shell 1, and the cover body 5 can be rotated to remove the obstruction of the shell 1. At this time, the wellhead can be observed.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
