[0047] This embodiment relates to a non-metal pipe auxiliary filling device. Among them, the non-metal pipe can be a non-metal oil and gas pipe or a non-metal pipe in other fields. In this embodiment, the non-metal oil and gas pipe is mainly used for demonstration.

[0048] Please refer to Figure 1 , the non-metal pipe auxiliary filling device of this embodiment includes a gripper 100 and a clamping bracket 200.

[0049] The clamping bracket 200 is used to place the non-metal pipe 300, and the non-metal pipe 300 is placed in a vertical posture. As Figure 1 shown, the non-metal pipe 300 is placed at the center of the clamping bracket 200, and its function is to provide support for the multiple grippers 100 to symmetrically clamp the non-metal pipe 300.

[0050] In some embodiments, please combine Figure 1 , 3, 4. The clamping bracket 200 is a welded frame, mainly formed by welding channel steels into a rectangular frame, with three short channel steels lapped in the middle, so that the clamping bracket 200 forms a frame structure to enhance the overall rigidity. There is a rectangular bottom plate at the bottom of the frame, and four small rib plates are provided between the frame and the bottom plate. The clamping bracket 200 is connected to the bottom plate and the base 400 by screws. Two rectangular steel plates are also welded on the surface of the frame of the clamping bracket 200, and light holes are opened in the rectangular steel plates at a certain interval for assembling the gripper 100.

[0051] The base 400 is a frame welded by rectangular channel steels, with rectangular steel plates welded on the upper and lower end faces, and threaded holes are opened in the rectangular steel plates at a certain interval for assembling the clamping bracket 200. Four rectangular plates with through holes are also welded near the base 400 for hoisting and positioning.

[0052] Please refer to Figure 4 , the clamping bracket 200 is provided with a plurality of mounting holes from top to bottom to be suitable for fixing the gripper 100 at different heights, and a plurality of grippers 100 are symmetrically installed on the clamping bracket 200 around the non-metallic pipe 300. That is, according to the length of the non-metallic pipe 300, a plurality of grippers 100 can be installed at different heights of the clamping bracket 200.

[0053] Therefore, in this embodiment, the non-metallic pipe auxiliary filling device can adapt to the filling of non-metallic pipes 300 of different specifications. When it is necessary to fill oil and gas pipes of different sizes and specifications, first, according to the length of the oil and gas pipe, the gripper 100 is installed at different hole positions of the clamping bracket 200 corresponding to the length of the oil and gas pipe, as Figure 4 shown. Then, according to the pipe diameter, the clamping bracket 200 is adjusted to a position close to the outer diameter of the oil and gas pipe and the base 400 of the clamping bracket 200 is fixed by screws, and finally the oil and gas pipe is fixed by the gripper 100.

[0054] Please refer to Figure 2 , the gripper 100 is installed on the clamping bracket 200. The gripper 100 at least includes a power part 110 and a clamping part 120, and the power part 110 drives the clamping part 120 to move to clamp or release the non-metallic pipe 300.

[0055] Start the power part 110, and the power part 110 can drive the clamping part 120 to gradually approach and clamp or disengage and release the non-metallic pipe 300 along the radial direction. When approaching and clamping the non-metallic pipe 300, the clamping part 120 realizes clamping and fixing the oil and gas pipe (non-metallic pipe 300) in the vertically placed state. At this time, the operator can fill the test medium.

[0056] Please continue to refer to Figure 2, the clamping part 120 includes a clamping arm 121 and a clamping tile 122. Among them, the clamping arm 121 is installed through the clamping bracket 200; the clamping tile 122 is fixed to the distal end of the clamping arm 121, and the arc of the clamping tile 122 conforms to the pipe wall of the non-metal pipe 300. The power part 110 drives the clamping arm 121 to move along the Figure 1 horizontal direction shown, and the clamping arm 121 carries the clamping tile 122 to gradually approach and clamp the non-metal pipe 300.

[0057] The clamping tile 122 is selected to be close to the non-metal pipe 300 to increase the contact area and clamp the non-metal pipe 300 with a stable clamping force.

[0058] In addition, in some embodiments, as Figure 1 shown, two sets of clamps 100 are symmetrically distributed on the clamping bracket 200, and the two clamps 100 in each group are symmetrically arranged with respect to the axial center line of the non-metal pipe 300.

[0059] In some embodiments, the clamping part 120 further includes a lining plate 123. The lining plate 123 is detachably and fixedly connected to the clamping tile 122, and the lining plate 123 is a curved plate, and its curved surface closely adheres to the pipe wall of the non-metal pipe 300. The lining plate 123 is arranged between the clamping tile 122 and the non-metal pipe 300, and the lining plate 123 is connected to the clamping tile 122 by screws, which can facilitate replacement after damage.

[0060] The clamping tile 122 is a steel plate with a circular arc curved surface, and four threaded holes are opened around the steel plate; screw counterbores are evenly distributed around the lining plate 123, and the lining plate 123 is connected to the clamping tile 122 by screws through the counterbores.

[0061] In some embodiments, the lining plate 123 is made of an elastic material.

[0062] And / or, the lining plate 123 has at least two parallel and opposite arc surfaces, and the arcs of the two arc surfaces are the same, which are the first arc surface and the second arc surface respectively. Among them, the first arc surface closely adheres to the clamping tile 122, and the second arc surface is covered with an elastic material and closely adheres to the pipe wall of the non-metal pipe 300.

[0063] The above-mentioned elastic material can be a polyurethane material, and the lining plate 123 made of polyurethane material can effectively avoid scratching the surface of the oil and gas pipe when clamping.

[0064] Such as Figure 2As shown, the clamping arm 121 includes at least a first arm and a second arm. Among them, the clamping tile 122 is fixed to the distal end of the first arm; the proximal end of the first arm extends axially to form a stepped shaft after diameter reduction, and an external thread is provided on the outer surface of the second arm, and the power unit 110 is sleeved on the second arm. That is, the first arm is a smooth large-diameter shaft, and the second arm is a threaded rod with a small diameter shaft. Such a design can not only achieve the installation of the power unit 110 and the axial movement of the clamping arm 121, but also save materials in the manufacturing stage.

[0065] In addition, the stepped shaft type clamping arm 121 can also play a role in limiting its movement.

[0066] In some embodiments, the clamping arm 121 can also be a through-threaded rod.

[0067] Please continue to refer to Figure 2 , the power unit 110 includes a panel 111, a sleeve 112, a handwheel 113 and a locking nut 114.

[0068] The panel 111 is fixed to the clamping bracket 200. The panel 111 is provided with a circular hole for the clamping arm 121 to pass through, and the distal end of the circular hole is a circular counterbore. The panel 111 is fixed to the clamping bracket 200 by bolts, and its purpose is to provide support for the rotation of the sleeve 112, the handwheel 113 and the locking nut 114.

[0069] The sleeve 112 is inserted into the circular hole of the panel 111. The distal end of the sleeve 112 extends radially to form a circular boss to fit and install in the circular counterbore of the panel 111. Its purpose is to limit the axial movement of the sleeve 112 and ensure that the sleeve 112 rotates in the circular hole of the panel 111. The inner wall of the sleeve 112 is provided with an internal thread, and the proximal end of the outer wall is provided with an external thread. Among them, the sleeve 112 and the clamping arm 121 are screwed together, that is, the internal thread of the sleeve 112 is screwed onto the external thread of the clamping arm 121.

[0070] The handwheel 113 is sleeved and screwed onto the external thread of the sleeve 112 through an internal thread. Rotating the handwheel 113 can control the clamping force of the gripper 100 on the oil and gas pipe.

[0071] The locking nut 114 is screwed onto the external thread of the sleeve 112.

[0072] The sleeve 112 can be restricted within the panel 111 by the locking nut 114 and the handwheel 113. Rotating the handwheel 113, the handwheel 113 drives the sleeve 112 to rotate. At this time, the clamping arm 121 moves axially along it, gradually approaching and clamping or disengaging and loosening the non-metallic pipe 300.

[0073] In some embodiments, the power unit 110 further includes a spacer ring 115, which is fixedly sleeved on the sleeve 112, and the spacer ring 115 is arranged between the panel 111 and the handwheel 113.

[0074] In some embodiments, the proximal circular hole of the panel 111 extends axially to form a spacer ring 115, and the handwheel 113 is seated on the proximal end of the spacer ring 115.

[0075] That is to say, the spacer ring 115 can be integral with the panel 111 or separable. Its function is to space the handwheel 113 and the panel 111 apart, leaving a certain operating space for the operator to rotate the handwheel 113.

[0076] Please continue to refer to Figure 2 , the outer cylindrical wall of the sleeve 112 is divided into a threaded section and a smooth section. The length of the threaded section is at least sufficient for the installation of the handwheel 113 and the locking nut 114. The spacer ring 115 and the panel 111 are sleeved on the smooth section. The outer diameter of the external thread of the threaded section is smaller than the outer diameter of the cylindrical surface of the smooth section, and the outer diameter of the smooth cylindrical surface is smaller than the outer diameter of the circular boss.

[0077] In some embodiments, the panel 111 is a welded part, which is formed by welding a rectangular steel plate and a steel pipe. The steel pipe is welded at the center position of the upper end face of the steel plate, and the diameter of the steel pipe is slightly larger than the outer diameter of the smooth cylindrical surface of the sleeve 112. Four through holes are distributed around the rectangular steel plate, and a circular counterbore is opened on the lower end face of the steel plate, which can be matched with the circular boss of the sleeve 112 for positioning.

[0078] The installation method of the non-metal pipe auxiliary filling device is as follows:

[0079] Insert the sleeve 112 into the installation hole of the panel 111 so that the circular boss of the sleeve 112 is matched with the circular counterbore of the panel 111; install the handwheel 113 at the external thread of the sleeve 112 and fix it with the locking nut 114. At this time, when the handwheel 113 is rotated, the sleeve 112 rotates in the same direction; connect the polyurethane lining plate 123 and the clamping tile 122 with an internal hexagonal screw; align the external threaded rod of the clamping arm 121 with the internal thread on the side of the circular boss of the sleeve 112, and rotate the handwheel 113 to make the clamping arm 121 penetrate through the sleeve 112; install the assembly of the gripper 100 through the through hole on the panel 111 and connect it to the clamping bracket 200 with bolts.

[0080] The usage method of the non-metal pipe auxiliary filling device is as follows:

[0081] Adjust the installation height of the gripper 100 to the upper and lower end positions of the oil and gas pipe and symmetrically fix it on the clamping bracket 200; control the installation spacing of the clamping bracket 200 at a position slightly larger than the outer diameter of the non-metal oil and gas pipe and fix the clamping bracket 200 on the base 400; place the non-metal oil and gas pipe between the two clamping brackets 200; rotate the handwheels 113 of the 4 grippers 100 in sequence to make the clamping arms 121 move forward, and finally make the lining plate 123 press the oil and gas pipe tightly. At this time, the oil and gas pipe is in a vertically fixed state, waiting for the filling of the experimental medium.

[0082] In this embodiment, the distance between the clamping brackets 200 is changed to meet the filling of experimental media for non-metallic oil and gas pipes of different specifications. The clamping tiles 122 with polyurethane liners 123 can effectively protect the surface quality of the oil and gas pipes. The non-metallic oil and gas pipes are clamped by the grippers 100 and placed vertically, which is convenient for the operator to fill the test media and has a good exhaust effect, helping to improve the quality of the hydrostatic test of non-metallic oil and gas pipes.

[0083] Those of ordinary skill in the art can understand that the above embodiments are specific embodiments for implementing the present utility model, and in actual applications, various changes can be made in form and details without departing from the spirit and scope of the present utility model.
