Description

Technical Field

[0001] The utility model relates to the technical field of pipe fittings, especially large-size ductile iron pipe storage and transportation, and in particular to a pipe fitting anti-squeezing and anti-slip device with a variable angle. Background Art

[0002] Ductile iron pipe refers to a pipe made by high-speed centrifugal casting in a centrifugal ductile iron machine after adding spheroidizing agent to molten iron above No. 18. It is referred to as ductile iron pipe, ductile iron pipe and ductile iron pipe for short. It is a pipe with excellent performance and is suitable for many fields, especially water supply, gas transmission, oil transmission and other pipeline systems.

[0003] When ductile iron pipes are stored or transported, they are often placed in parallel stacking or in a staggered stacking manner, as shown in the following figure: Figure 1 and Figure 2 As shown, however, for large and heavy ductile iron pipes, the above two stacking methods are prone to cause pipe crushing or sliding. Therefore, it is necessary to propose a pipe anti-crushing and anti-slip device with a variable angle that can adapt to the above two stacking methods at the same time. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a variable-angle anti-squeezing and anti-slip device for pipe fittings. The variable-angle anti-squeezing and anti-slip device for pipe fittings is placed between two pipe fittings (ductile iron pipes) stacked up and down, which can not only effectively prevent the two pipe fittings from squeezing each other, but also prevent the pipe fittings from sliding against each other. At the same time, the universality of the two stacking methods is achieved through the mutually rotatable connection between the upper half and the lower half.

[0005] The technical solution of the utility model is as follows:

[0006] A variable-angle pipe anti-squeeze and anti-slip device comprises an upper body, a lower body and a swivel joint, wherein the upper body is a plate-like structure with a concave arc shape whose cross section matches the pipe shape, and the lower body is a plate-like structure with a convex arc shape whose cross section matches the pipe shape, and the bottom of the upper body and the top of the lower body are rotatably connected to each other via a swivel joint.

[0007] The arc length of the upper half or the lower half is no greater than one quarter of the circumference of the tube.

[0008] The anti-squeeze and anti-slip devices for pipe fittings are made of metal or plastic.

[0009] The upper body and the lower body are both formed by cutting and modifying steel pipes; the steel pipes are carbon steel pipes or alloy steel pipes.

[0010] The upper body and the lower body are formed by bending steel plates; the steel plates are carbon steel plates or alloy steel plates.

[0011] The swivel joint is a rivet.

[0014] 1. The utility model discloses a variable-angle anti-squeezing and anti-slip device for pipe fittings. The variable-angle anti-squeezing and anti-slip device for pipe fittings is placed between two pipe fittings stacked up and down, which can not only effectively prevent the two pipe fittings from squeezing each other, but also prevent the pipe fittings from sliding against each other.

[0015] 2. The utility model discloses a variable-angle anti-squeezing and anti-slip device for pipe fittings, which realizes the commonality of two stacking methods through the mutually rotatable connection between the upper half and the lower half.

[0024] Example 1

[0025] like Figure 3As shown, the variable-angle pipe anti-squeeze and anti-slip device of this embodiment includes an upper body 2, a lower body 3 and a swivel joint 4, wherein the upper body 2 is a plate-like structure with a concave arc shape whose cross section matches the shape of the pipe 1, and the lower body 3 is a plate-like structure with a convex arc shape whose cross section matches the shape of the pipe 1. Preferably, the arc length of the upper body 2 or the lower body 3 is not greater than one-fourth of the circumference of the pipe 1, and the bottom of the upper body 2 and the top of the lower body 3 are rotatably connected to each other through the swivel joint 4. The swivel joint 4 is a rivet. During manufacturing, a rivet hole is opened at the position where the upper body 2 and the lower body 3 are combined. After the rivet is inserted into the rivet hole, a rivet gun or a riveting machine is used to complete the riveting work. A gap is left between the upper body 2, the lower body 3 and the swivel joint 4 to facilitate the mutual rotation of the upper body 2 and the lower body 3; the upper pipe fitting 1 is placed on the upper body 2, and the lower body 3 is placed on the lower pipe fitting 1. The upper body 2 and the lower body 3 are rotatably connected through the swivel joint 4, so that they can be in a parallel relationship or a staggered relationship.

[0026] The pipe anti-squeeze and anti-slip device is made of metal, plastic or fiber.

[0027] Optionally, the upper body 2 and the lower body 3 are formed by bending steel plates; the steel plates are carbon steel plates or alloy steel plates.

[0028] There is also a relatively low-cost manufacturing method, that is, the upper half 2 and the lower half 3 are both cut and modified from steel pipes; the steel pipes are carbon steel pipes or alloy steel pipes.

[0029] In order to further protect the contact between the pipe 1 (ductile iron pipe) and the upper half or the lower half, as Figure 3 As shown, an elastic pad is provided on the inner arc surface of the upper body 2 or the lower body 3.

[0030] In a specific embodiment, the elastic pad is a rubber pad 5 , and the rubber pad 5 is glued and fixed to the inner curved surface of the upper body 2 or the lower body 3 .

[0031] In such Figure 3 In the state shown, it can be used as Figure 1 Two parallel stacked pipes 1 are shown.

[0032] Will be like Figure 3 The upper body 2 in the state shown is rotated 90 degrees to the left or right, so that the upper body 2 and the lower body 3 are in an orthogonal state, and can be used as follows: Figure 2 The two upper and lower pipes 1 are shown to be vertically staggered and stacked.

[0033] The variable-angle pipe anti-squeeze and anti-slip device is placed between two pipes 1 (ductile iron pipes) stacked up and down, which can not only effectively prevent the two pipes 1 from squeezing each other, but also prevent the pipes 1 from sliding against each other. At the same time, the universality of the two stacking methods is achieved through the mutually rotatable connection between the upper and lower halves.

[0034] It should be noted that although the pipe fittings in the utility model take ductile iron pipes as an example, they are not limited to ductile iron pipes. The embodiments provided by the utility model are only preferred implementation objects or implementation methods. Any technician familiar with the technical field within the technical scope disclosed by the utility model can make equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, which should be covered by the protection scope of the utility model.
