[0002] Epoxy glass composite steel pipes are highly corrosion-resistant and have high mechanical strength, enabling them to resist the erosion of chemicals such as acids, alkalis, and salts. They can be used to transport corrosive industrial wastewater and chemical raw materials. The smooth inner wall reduces water flow resistance, effectively reducing energy loss during fluid transportation, improving transportation efficiency, and lowering operating costs. They are particularly suitable for long-distance water and oil pipeline systems. The oxygen coating is non-toxic and odorless, meeting hygiene standards, and can be used for drinking water transportation, ensuring that water quality is not polluted and protecting the safety of residents' drinking water.

[0003] When epoxy glass composite steel pipes are used as directional crossing pipes, they need to be dragged into the preset points. Therefore, it is necessary to test the wear resistance of epoxy glass composite steel pipes. However, there is a lack of corresponding testing equipment in the existing technology. Utility Model Content

[0004] In view of the above problems, this application provides an epoxy glass composite steel pipe testing device, which can test the wear resistance of epoxy glass composite steel pipes, and the operation process has good controllability and can simulate wear under various conditions.

[0005] According to one aspect of the embodiments of this application, an epoxy glass composite steel pipe testing device is provided. The epoxy glass composite steel pipe testing device includes a cement base. Multiple strip-shaped steel channels are provided on the top of the cement base.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and the foregoing description of the accompanying drawings are intended to cover non-exclusive inclusion.

[0020] For details, please refer to Figure 1 and Figure 2 . Figure 1 This is a schematic diagram of the overall structure of the device provided in an embodiment of this application. Figure 2 A partial structural diagram is provided for an embodiment of this application. The epoxy glass composite steel pipe testing device 100 includes a cement base 110, which is formed by pouring cement onto the ground. During the pouring process, attention should be paid to the flatness. Multiple strip-shaped steel channels 111 are provided on the top of the cement base 110. The strip-shaped steel channels 111 can be made using U-shaped steel rails 112, which can be embedded within the cement base 110. A steel rail 112 is slidably installed inside a strip-shaped steel channel 111. Two movable platforms 120 are fixedly connected to the top of the multiple steel rails 112. The two movable platforms 120 are symmetrically arranged at both ends of the steel rails 112. The movable platforms 120 and the strip-shaped steel rails 112 can be integrated into a single structure. A drive assembly 130 for moving the movable platforms 120 is shared between the movable platforms 120 and the cement base 110. During operation, the drive assembly 130 can drive the movable platforms 120 and the strip-shaped steel rails 112 to slide together along the axial direction of the strip-shaped steel rails 112 within their internal tracks. A sand box assembly 140 is installed between the two movable platforms 120. The sand box assembly 140 is filled with natural sand and is fixed to the top of the cement base 110. The position of the sand box assembly 140 does not change with the movable platforms 120 or the steel rails 112. The steel pipe under test is rubbed by the natural sand inside the sand box assembly 140 as it continuously passes through it. The top of the moving stage 120 is connected to a V-shaped support platform 150 via a support frame. Rollers 151 and friction wheels 152 are rotatably connected to both ends of the support platform 150. A rotating motor 153 is connected to one end of the friction wheel 152. When the steel pipe to be tested is placed on top of the support platform 150, the rotating motor 153 drives the friction wheel 152 to rotate. The friction wheel 152 causes the steel pipe to rotate by rubbing against its outer wall. A stopping component 160 is provided on one side of the support platform 150 at the top of the moving stage 120, abutting against both ends of the steel pipe to be tested. The stopping component 160 abuts against both ends of the steel pipe, allowing the moving stage 120 to move along with the steel pipe during its movement. The sand box assembly 140 includes a main body 141 fixed to a cement base 110 by a support frame. A cylindrical extension 142 is fitted onto the top of the main body 141. The main body 141 and the extension 142 can be fixed together using screws or other methods. Both ends of the main body 141 and the extension 142 have circular holes 143 for steel pipes to pass through. Each circular hole 143 is formed by two semicircles respectively located on the main body 141 and the extension 142. A counterweight block 144 is installed inside the extension 142. The counterweight block is used to compress the natural sand inside the sand box, further increasing the pressure between the natural sand and the steel pipe to be tested, thus changing their friction.

[0021] In this embodiment, during operation, the steel pipe to be tested is hoisted and placed on two support platforms 150. The roller 151 and friction wheel 152 abut against the outer wall of the steel pipe. The extension box 142 is then snapped onto the top of the main body 141 and fixed. The rotating motor 153 is then turned on, driving the friction wheel 152 to rotate, which in turn drives the steel pipe to rotate. When the steel pipe begins to rotate smoothly, natural sand is poured into the sand box assembly 140 and a counterweight is added. The pressure block 144 is placed on top of the natural sand. At this time, the natural sand inside the sand box will rub against the outer wall of the steel pipe to be tested. After a period of time, the rotation is turned off and the blocking component 160 is configured so that the blocking component 160 abuts against both ends of the steel pipe to be tested. The drive assembly 130 is turned on, and the drive assembly 130 drives the moving table 120, the blocking component 160, the steel pipe to be tested, and the strip rail 112 to slide together along the axial direction of the strip rail 112. At this time, the natural sand inside the sand box continues to rub against the outer wall of the steel pipe to be tested. The steel pipe to be tested is rubbed back and forth in the sand box. After a period of time, the equipment is turned off, the counterweight pressure block 144 and the extension box 142 are removed in sequence, and then the steel pipe to be tested is removed to observe its wear degree.

[0022] As can be seen from the above, in this embodiment of the application, by setting up components such as the strip steel channel 111, the rail 112, the moving platform 120, the support platform 150, and the blocking component 160 to cooperate with each other, the steel pipe to be tested can be moved along its axial direction. By setting up the sand box assembly 140, the natural sand inside the sand box assembly 140 can rub against the outer wall of the steel pipe to be tested during the movement of the steel pipe, so as to simulate the friction state experienced by the epoxy glass composite steel pipe as a directional passage pipe. The sand box assembly 140 includes a mating box body 141 and an extension box body. 142 not only satisfies the requirement of wrapping natural sand, but also allows the steel pipe to be tested to be easily placed inside the sand box assembly 140. In this application, by setting up a support platform 150, friction wheel 152 and rotating motor 153 and other components to cooperate with each other, the device can drive the steel pipe to be tested to rotate around its circumference. Since the outer coating and glass cloth layer of the epoxy glass composite steel pipe are wrapped on its outside in a rotating manner, the firmness of the adhesion of the outer coating of the epoxy glass composite steel pipe can be tested during the rotation and friction of the epoxy glass composite steel pipe.

[0023] In some embodiments, the blocking component 160 includes a flap 161 and a rotating rod 162 connected to the top of the moving platform 120 by a hinge. A striped plate 163 is vertically arranged on the side of the flap 161 away from the support platform 150. A first striped groove is uniformly arranged on the striped plate 163. A locking block 164 is hinged to the free end of the rotating rod 162. A second striped groove matching the striped plate 163 is provided on one side of the locking block 164.

[0024] In this embodiment, a specific arrangement of the blocking component 160 is shown. During operation, when the steel pipe to be tested is hoisted to a preset position, the flap 161 can be rotated to make it vertical. Then, the rotating rod 162 is rotated so that the end block 164 abuts against the striped plate 163 and presses it tightly. At this time, the first striped groove on the striped plate 163 and the second striped groove on the block 164 intersect and fit together, so that the rotating rod 162 can be stably supported on the outside of the flap 161, so that the flap 161 remains vertical and completes the blocking of the steel pipe to be tested.

[0025] In some embodiments, positioning rods 142a are respectively provided at both ends of the extension box 142, and receiving ports 141a that match the positioning rods 142a are respectively provided at both ends of the box body 141. In this embodiment, the positioning between the box body 141 and the extension box 142 is facilitated by the above-mentioned rods and receiving ports 141a.

[0026] In some embodiments, a rubber sealing ring is provided at the top end face of the main body 141. The top two sides of the main body 141 extend outwards to form a first platform 141b, and the two sides of the extended box 142 extend outwards to form a second platform 142b. The first platform 141b and the second platform 142b are connected by screws. In this embodiment, the rubber sealing ring increases the sealing effect of the sand box assembly 140, reducing sand leakage during operation. The first platform 141b and the second platform 142b facilitate the fixing between the main body 141 and the extended box 142.

[0027] In some embodiments, the drive assembly 130 includes a drive motor 131 and a rotating shaft 132. A driven sprocket 133 is disposed in the middle of the rotating shaft 132. The output end of the drive motor 131 is connected to the sprocket via a ring toothed chain 134. Drive wheels 135 are disposed at both ends of the rotating shaft 132, and the drive wheels 135 are rolledly connected to the cement base 110. For ease of explanation, this application embodiment provides a specific arrangement of the drive assembly 130. During operation, after the drive motor 131 is turned on, it drives the rotating shaft 132 to rotate. In turn, the rotating shaft 132 drives the two drive wheels 135 to rotate, thereby driving the components such as the moving platform 120. It should be noted that in this application embodiment, the moving direction of the components such as the moving platform 120 is changed by adjusting the rotation direction of the drive motor 131.

[0028] In some embodiments, the movable stage 120 is provided with a plurality of positioning holes 121 along a straight line, and a screw is provided at the rail 112, with the screw inserted into the positioning holes 121. In this embodiment, through the above-described configuration, the rail 112 and the movable stage 120 are detachably connected. Therefore, when the length of the steel pipe to be inspected is different, the position of the movable stage 120 on the rail 112 can be adjusted, and then the movable stage 120 can be re-fixed to the rail 112 using the screw.

[0029] In some embodiments, a recovery hopper 170 is provided at the bottom of the sand box assembly 140, and a sand outlet 171 is provided on one side of the recovery hopper 170. In this embodiment, the natural sand leaking from the sand box assembly 140 is collected by the recovery hopper 170 and swept out through the sand outlet 171.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although the foregoing embodiments have provided a detailed description of this application, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
