Description

Technical Field

[0001] This invention relates to a quick-connect pipe fitting device, belonging to the field of pipeline maintenance technology. Background Technology

[0002] The various pipelines used in underground mines, such as compressed air, water supply, cooling, and nitrogen injection, provide necessary safety guarantees for mine production. However, due to the use and maintenance of these pipelines, as well as objective conditions (such as roadway bulging, floor bulging, or other situations causing pipeline joints to break), maintenance work is required to disconnect and reconnect the pipelines. Due to geological factors or the influence of mining design, the roadways are uneven, and various pipelines, under different tension forces, will experience varying degrees of tearing and misalignment once they break. Moreover, due to the limited space of the pipelines, it is difficult to connect the pipeline joints. Generally, three people use a hand-operated hoist to adjust the pipelines back and forth, which greatly restricts the efficient production of the mine and wastes manpower and resources.

[0003] Therefore, we have been constantly seeking and exploring ways to efficiently, quickly and safely connect pipelines. We have effectively solved this problem by developing a quick-connect pipeline connector device. This technology is applicable to various environmental conditions in underground mines. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is: to solve one of the above problems, a quick connection pipe joint device is provided for connecting two pipe joints. In addition, the device has low processing cost, can be processed and used from waste materials, and is more economical in terms of materials compared with hand chain hoist equipment. It is also more convenient to use and more accurate in positioning.

[0005] The quick-connect pipe fitting device of the present invention is characterized in that it includes a first pipe connector fixed to one end of a first pipe and a second pipe connector fixed to one end of a second pipe. The first pipe connector and the second pipe connector are connected together by a connector. The first pipe connector and the second pipe connector are first connected together by the connector, then the first pipe connector is fixed to the first pipe, then the second pipe connector is fixed to the second pipe, and finally the connector is used to bring the distance between the first pipe connector and the second pipe connector closer. Because the first pipe connector is fixed to the first pipe and the second pipe connector is fixed to the second pipe, the open ends of the first pipe and the second pipe are brought closer together, and the two pipe fittings are connected.

[0006] Furthermore, the first pipe connector includes a first rectangular pipe section parallel to the first pipe. The first rectangular pipe section is a hollow rectangular steel pipe. A first rope winder and a second rope winder are spaced apart along the length of the upper surface of the first rectangular pipe section. It also includes a first steel wire rope and a second steel wire rope sleeved on the outside of the first pipe. One end of the first steel wire rope is wound around the first rope winder, and the other end is fixed to the lower surface of the first rectangular pipe section. One end of the second steel wire rope is wound around the second rope winder, and the other end is fixed to the lower surface of the first rectangular pipe section. After the first and second steel wire ropes are tightened, the first steel wire rope and the second steel wire rope are parallel to each other, and the first rectangular pipe section is pressed tightly against the outer wall of the first pipe. First, assemble the first pipe connector, the second pipe connector, and the connector between the joints together. Then, tighten the first pipe connector. Next, fix the first and second steel wire ropes of the first pipe connector to the lower surface of the first rectangular pipe section using conventional hooks. The other ends of the first and second steel wire ropes are wrapped around the first pipe and connected to the first and second rope winding devices, respectively. Use manual power to drive the first and second rope winding devices to tighten the first and second steel wire ropes until they are parallel to each other and the first rectangular pipe section is pressed against the outer wall of the first pipe, thus achieving relative fixation between the pipe and the first pipe connector.

[0007] Furthermore, the second pipe connector includes a second rectangular pipe section parallel to the second pipe. The second rectangular pipe section is a hollow rectangular steel pipe. A third and a fourth rope winding device are spaced apart along the length of the upper surface of the second rectangular pipe section. It also includes a third and a fourth steel wire rope sleeved on the outside of the first pipe. One end of the third steel wire rope is wound around the third rope winding device, and the other end is fixed to the lower surface of the second rectangular pipe section. One end of the fourth steel wire rope is wound around the fourth rope winding device, and the other end is fixed to the lower surface of the second rectangular pipe section. After the third and fourth steel wire ropes are tightened, they are parallel to each other, and the second rectangular pipe section is pressed tightly against the second pipe. After the tightening step of the first pipe connector is completed on the outer wall of the pipe, the tightening step of the second pipe connector needs to be carried out. The third and fourth steel wire ropes of the second pipe connector need to be fixed to the lower surface of the second rectangular pipe section respectively. Conventional hooks can be used for connection. The other ends of the third and fourth steel wire ropes are wrapped around the second pipe and connected to the third and fourth rope winding devices respectively. The third and fourth rope winding devices are manually driven to tighten the third and fourth steel wire ropes respectively until the third and fourth steel wire ropes are parallel to each other and the first rectangular pipe section is pressed against the outer wall of the first pipe, so as to achieve relative fixation between the pipe and the second pipe connector.

[0008] Furthermore, a connecting support wall A is vertically connected to the outer wall of the first rectangular tube segment, and a plurality of connecting holes A connected to the connecting screw are spaced apart along its length direction on the connecting support wall A. A connecting support wall B is vertically connected to the outer wall of the second rectangular tube segment, and a plurality of connecting holes B connected to the connecting screw are spaced apart along its length direction on the connecting support wall B. The connecting holes A and connecting holes B are configured to cooperate and provide a connection part for the connecting screw.

[0009] Furthermore, the connector between the joints includes a connecting screw and a plug rod. One end of the connecting screw is connected to the connecting support wall A through a connecting hole A on the connecting support wall A, and the other end of the connecting screw is connected to the connecting support wall B through a connecting hole B on the connecting support wall B. One end of the plug rod is inserted into the first rectangular pipe segment and can slide relative to the first rectangular pipe segment. The other end of the plug rod is inserted into the second rectangular pipe segment and can slide relative to the second rectangular pipe segment. By operating the connecting screw, the distance between the second rectangular pipe segment and the first rectangular pipe segment can be shortened, and the plug rod provides a guiding function for the first rectangular pipe segment and the second rectangular pipe segment, making it possible to finally connect the two pipe joints.

[0010] Furthermore, the connecting screws are provided in multiple forms, including a first screw that penetrates the connecting support wall A and a second screw that penetrates the connecting support wall B. The first screws are connected to each other by a threaded tube. The threads of the first screw and the second screw have opposite directions. Rotating the threaded tube can increase the screwing depth of the first screw and the second screw, so as to shorten the distance between the first pipe connector and the second pipe connector.

[0011] Furthermore, a connecting rib is provided between the first rectangular tube segment and the connecting support wall A, and a connecting rib is provided between the second rectangular tube segment and the connecting support wall B.

[0012] Furthermore, the first wire rope is a composite multi-strand first wire rope.

[0013] The construction steps of this invention are as follows:

[0014] Step 1: First, assemble the first pipe connector, the second pipe connector, and the connector between the connectors together. Insert both ends of the plug rod into the first rectangular pipe section and the second rectangular pipe section respectively. Connect the two ends of the connecting screw to the connecting support wall A and the connecting support wall B respectively.

[0015] Step 2: Tighten the first pipe connector. Then, fix the first and second steel wire ropes of the first pipe connector to the lower surface of the first rectangular pipe section. A conventional hook connection can be used. The other ends of the first and second steel wire ropes are wrapped around the first pipe and connected to the first rope winding device and the second rope winding device, respectively. Use manual power to drive the first and second rope winding devices to tighten the first and second steel wire ropes, respectively, until the first and second steel wire ropes are parallel to each other and the first rectangular pipe section is pressed against the outer wall of the first pipe, so as to achieve relative fixation between the pipe and the first pipe connector.

[0016] Step 3: After completing the tightening step of the first pipe connector, the tightening step of the second pipe connector needs to be performed. The third and fourth steel wire ropes of the second pipe connector need to be fixed to the lower surface of the second rectangular pipe section respectively. Conventional hooks can be used for connection. The other ends of the third and fourth steel wire ropes are wrapped around the second pipe and connected to the third and fourth rope winding devices respectively. The third and fourth rope winding devices are manually driven to tighten the third and fourth steel wire ropes respectively until the third and fourth steel wire ropes are parallel to each other and the first rectangular pipe section is pressed against the outer wall of the first pipe, so as to achieve relative fixation between the pipe and the second pipe connector.

[0017] Step 4: By operating the connecting screw, the distance between the second rectangular pipe segment and the first rectangular pipe segment can be shortened, and the plug rod provides guidance for the first rectangular pipe segment and the second rectangular pipe segment, and finally the two pipe joints are connected.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The quick-connect pipe fitting device of the present invention involves first connecting a first pipe connector and a second pipe connector together via a connector between connectors, then fixing the first pipe connector to the first pipe, then fixing the second pipe connector to the second pipe, and finally using the connector between connectors to bring the first and second pipe connectors closer together. Because the first pipe connector is fixed to the first pipe and the second pipe connector to the second pipe, the open ends of the first and second pipes are brought closer together, thus connecting the two pipe fittings. Furthermore, this device has low processing costs, can be processed using scrap materials, and is more economical in terms of materials compared to using a hand chain hoist, making it more convenient to use and providing more accurate positioning.
