Description

Technical Field

[0001] The utility model belongs to the technical field of high-pressure pipe manifolds, and particularly relates to a connection structure of a high-pressure pipe manifold. Background Art

[0002] A high-pressure pipe manifold connection structure is a device capable of connecting two high-pressure pipe manifolds without welding. For example, a high-pressure pipe manifold connection structure with a publication number of CN217583572U includes a high-pressure pipe manifold body and a fixed connection assembly. First flanges and second flanges are respectively fixedly connected to both ends of the high-pressure pipe manifold body. However, there are still some problems in the actual use of this connection structure. For example, during the connection of high-pressure pipe manifolds, operators need to rotate the two high-pressure pipe manifolds until the holes on the high-pressure pipe manifolds are aligned before they can be connected and fixed. Since the high-pressure pipe manifolds are heavy, it is rather difficult to rotate them, which greatly increases the labor intensity of the operators and makes it inconvenient to use. Summary of the Utility Model

[0003] In order to solve the above-mentioned existing technical problems, the utility model provides a connection structure of a high-pressure pipe manifold, which can achieve the effect of connecting high-pressure pipe manifolds without rotation, effectively reduce the labor intensity of operators, and is more convenient to use.

[0004] Its technical solution is as follows: A connection structure of a high-pressure pipe manifold includes two relatively arranged high-pressure pipe manifold bodies. It is characterized in that docking rings are integrally connected to the inner sides of the outer walls of the high-pressure pipe manifold bodies, and a rubber sealing ring is arranged between the docking rings. A non-positioning docking assembly is sleeved on the outer sides between the docking rings, and the non-positioning docking assembly can apply pressure to the docking rings.

[0005] Preferably, the non-positioning docking assembly includes two relatively arranged semi-circular docking plates. Connecting blocks are integrally connected to the front and rear sides of the semi-circular docking plates, and through holes are respectively formed in the left and right sides at the middle part inside the connecting blocks. Tightening bolts are installed inside between the upper through hole and the lower through hole. Threaded through holes are respectively formed in the left and right parts of the semi-circular docking plates from front to back, and pressing bolts are threadedly connected inside the threaded through holes.

[0006] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0007] In the utility model, the settings of the docking rings, semi-circular docking plates, connecting blocks, tightening bolts and pressing bolts are beneficial to achieve the effect of connecting high-pressure pipe manifolds without rotation, effectively reduce the labor intensity of operators, and are more convenient to use.

[0014] The present utility model will be specifically described below with reference to the accompanying drawings. As shown in the accompanying Figure 1 and the accompanying Figure 2 figures, a high-pressure manifold connection structure includes two oppositely arranged high-pressure manifold bodies 1. Inner sides of outer walls of the high-pressure manifold bodies 1 are integrally connected with docking rings 2 respectively, and a rubber sealing ring is arranged between the docking rings 2.

[0015] One of the high-pressure manifold connection structures further includes a positioning-free docking assembly 3, and the positioning-free docking assembly 3 is sleeved on the outer sides between the docking rings 2. By means of the positioning-free docking assembly 3, pressure can be applied to the docking rings 2, which is beneficial to achieving the effect of connecting the high-pressure manifolds without rotation, can effectively reduce the labor intensity of operators, and is more convenient to use.

[0016] In this embodiment, as shown in the accompanying Figure 3 and the accompanying Figure 4 figures, the positioning-free docking assembly 3 includes two oppositely arranged semi-circular docking plates 31. Connecting blocks 32 are integrally connected to the front and rear sides of the semi-circular docking plates 31 respectively, and through holes are respectively formed in the left and right sides of the middle part inside the connecting blocks 32. Fastening bolts 33 are installed inside the upper through holes and the lower through holes respectively; threaded through holes are respectively formed in the left and right parts of the semi-circular docking plates 31 from front to back, and pressing bolts 34 are respectively threadedly connected inside the threaded through holes.

[0017] In this embodiment, specifically, the semi-circular docking plates 31 are respectively sleeved on the upper and lower parts of the outer sides between the docking rings 2.

[0018] In this embodiment, specifically, the inner ends of the pressing bolts 34 respectively abut against the outer peripheral parts of the docking rings 2.

[0019] In this implementation scheme, specifically, the semi-circular docking plate 31 is made of a semi-circular alloy steel plate with a U-shaped longitudinal section.

[0020] In this implementation scheme, specifically, the connecting block 32 is made of an alloy steel block with a rectangular cross-section.

[0021] In this implementation scheme, when connecting the high-pressure pipe manifold body 1, the operator can first arrange the high-pressure pipe manifold body 1, and then the operator can directly sleeved the semi-circular docking plates 31 on the upper and lower outer sides between the docking rings 2 respectively, and fasten the connecting blocks 32 arranged on the upper side and the connecting blocks 32 arranged on the lower side through the fastening bolts 33. Then the operator can rotate the pressing bolts 34 by an external wrench until the inner ends of the pressing bolts 34 respectively abut against the outer sides of the docking rings 2. At this time, the docking rings 2 will be subjected to an inward squeezing force, and the two docking rings 2 will be closely fitted, thus completing the connection of the high-pressure pipe manifold body 1. Compared with the prior art, the utility model only needs to sleeve the semi-circular docking plates 31 on the upper and lower outer sides between the docking rings 2 and tighten the pressing bolts 34. During the installation of the semi-circular docking plates 31, it is not necessary to rotate the high-pressure pipe manifold body 1, realizing the effect of connecting the high-pressure pipe without rotation, which can effectively reduce the labor intensity of the operator and is more convenient to use.

[0022] Any technical solution using the technical solution of the present utility model, or designed by those skilled in the art inspired by the technical solution of the present utility model to achieve the above technical effects, shall fall within the protection scope of the present utility model.
