Description

Technical Field

[0001] The invention relates to the technical field of water conservancy equipment, and in particular to a pipeline connection and support device used in water conservancy projects. Background Art

[0002] During the construction of water conservancy projects, it is inevitable to lay pipes, and the laying of pipes requires the use of connecting and supporting devices.

[0003] However, as far as the current traditional connection and support devices are concerned, when the existing devices are in use, there are mostly only two ways to connect the pipes, namely flanges and welding. Both of these ways are time-consuming and labor-intensive to use, and it is impossible to automatically fix the two pipes when they are butted together through structural improvements; in addition, when the existing connection and support devices are in use, they are unable to achieve the sealing work for the butt ends of the pipes when the two pipes are butted together, which results in the need to separate the pipe sealing work from the pipe connection work, which directly reduces the efficiency of pipe laying.

[0011] Beneficial Effects

[0012] Compared with the traditional connection and support device, the connection and support device according to each embodiment of the present invention inserts the main column on one connection disk into the main groove of another connection disk, so that the main column pushes the inclined surface of the main limit block, causing the main limit block to shrink under force until the main column is completely inserted into the main groove. The main limit block is then engaged into the interior of the main groove under the action of spring A, so that the two tubes are connected and fixed in the first step.

[0013] In addition, when the main column is inserted into the main groove, the auxiliary column will be inserted into the auxiliary groove at the same time, so that the auxiliary column pushes the inclined surface of the auxiliary limit block, causing the auxiliary limit block to shrink under force until the auxiliary column is completely inserted into the auxiliary groove. Under the action of spring B, the auxiliary limit block is engaged into the auxiliary groove, so that the two tubes are further fixed, effectively ensuring the reliability of the connection between the two tubes.

[0014] In addition, the present invention only needs to push the two pipe bodies inward so that the force drives the two connecting plates to gradually approach each other, so that the connecting components on the two connecting plates are mutually engaged, thereby automatically completing the connection work of the pipe bodies after the two pipe bodies are spliced. Compared with manual welding fixed connection or manual connection through flanges, it saves time and labor, avoids the staff from spending too much time on fixing the pipe bodies, and improves the efficiency of pipeline laying.

[0015] Moreover, when the present invention pushes the tube body inward, the tube body drives the side plates and the pressure block to move inward, so that they push the inclined surface of the force-bearing block, so that the force-bearing block drives the cross bar and the sealing plate A to move inward, so that the sealing plate A pushes the sealing gasket A toward the connecting end of the tube body, and the sealing plate A cooperates with the tube body to squeeze the sealing gasket A, so that the sealing gasket A seals a part of the tube body.

[0016] Moreover, when the tube body moves inward, it will drive the push frame to move inward, so that the push frame pushes the sliding member, so that the sliding member drives one end of the connecting rod to move inward, so that the other end of the connecting rod pushes the vertical rod and the sealing plate B inward, so that the sealing gasket B is pushed toward the connecting end of the tube body, so that the sealing plate B cooperates with the tube body to squeeze the sealing gasket B, so that it seals the remaining part of the tube body, so that the two sets of sealing members cooperate to form a complete sealing ring, which completely seals the connecting end of the tube body and prevents water leakage at the connecting end of the tube body.

[0017] Through structural improvements, the present invention promotes the docking of two pipes and realizes the sealing and waterproofing of the connecting ends of the pipes at the same time, so that the connection and sealing of the pipes can be carried out simultaneously. Compared with performing the two tasks separately, it saves more time and labor, and improves the efficiency of pipeline laying by 15%-20%. BRIEF DESCRIPTION OF THE DRAWINGS
