Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic testing equipment, and in particular to a pipe reel structure for hydraulic testing equipment. Background Technology

[0002] Hydraulic testing equipment is an important testing device used to test the pressure resistance, sealing performance, fatigue life, and other properties of fluid transport components such as hydraulic hoses, metal pipes, and rubber hoses. It is widely used in various industrial fields, including automotive manufacturing, aerospace, shipbuilding, and oil exploration. In practical applications, these testing devices typically require a piping system of a certain length to connect with the tested component and transmit pressure. Therefore, how to efficiently and safely manage these testing pipes, ensuring smooth unwinding and rewinding during testing, becomes a crucial factor affecting the overall operational efficiency and safety of the testing system.

[0003] Currently, conventional hydraulic testing equipment mostly uses a simple reel structure or manual winding method to manage the test pipeline. When the test ends or is paused, the pipeline will be in a slack state due to gravity or external tension, lose tension control, and cannot stay stably on the reel. The pipeline is prone to loosening, slipping, knotting, etc., which not only affects subsequent operations, but may also cause equipment damage or personal injury due to sudden pipeline loosening. Utility Model Content

[0004] The purpose of this invention is to provide a pipe reel structure for a hydraulic testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe reel structure for a hydraulic testing equipment, comprising a hydraulic testing equipment housing, wherein a pipe reel mechanism for unwinding pipes during hydraulic testing is provided on one outer wall of the hydraulic testing equipment housing, the pipe reel mechanism comprising two symmetrically arranged support side ears, a reel component rotatably mounted between the two support side ears, and a servo motor mounted on the outer wall of one of the support side ears and driving the reel component to rotate, a finger cylinder is provided in front of the reel component, and two clamping claws are symmetrically arranged at the working end of the finger cylinder, the pipe passes through the two clamping claws and is wound onto the reel component, when unwinding the pipe is not required, the finger cylinder drives the two clamping claws to move centripetally to clamp the pipe, so that the two clamping claws clamp the pipe, and a swing arm assembly is also provided on the outer wall of one of the support side ears for driving the finger cylinder to swing arc-shaped along the outer circumference of the reel component to adjust the position and angle of the finger cylinder, when the swing arm assembly drives the finger cylinder to move arc-shaped, the finger cylinder clamps the pipe and bends the pipe to lock the slack of the pipe.

[0006] In a preferred embodiment, one of the supporting side ear plates has an extended mounting plate welded to its outer wall. The swing arm assembly includes a drive motor mounted on the outer wall of the extended mounting plate, a swing arm mounted on the output shaft of the drive motor, and a mounting plate integrally connected to the free end of the swing arm.

[0007] In this preferred embodiment, the finger cylinder is fixedly connected to the mounting plate at its tail end by bolts, so that the position of the finger cylinder can be adjusted when the drive motor drives the rocker arm to swing in an arc.

[0008] In this preferred embodiment, the end of the finger cylinder furthest from the mounting plate is connected to another supporting side ear plate via a positioning bracket, forming a positioning mechanism for the finger cylinder to swing and move in an arc shape in front of the reel.

[0009] In a preferred embodiment, the positioning bracket includes a U-shaped positioning fork welded to the opposite side of the two gripping claws and located on the outer wall of the free end of the finger cylinder, and a positioning swing arm welded to the back of the U-shaped positioning fork.

[0010] In a preferred embodiment, the end of the positioning arm furthest from the U-shaped positioning fork is rotatably connected to another supporting side plate via a pin.

[0011] In this preferred embodiment, the inner walls of both gripping claws are bonded with anti-slip rubber pads, and the two anti-slip rubber pads are in frictional contact with the pipe.

[0012] In this preferred embodiment, the outer wall of the hydraulic testing equipment housing is bolted with a mounting base, the pipe reel mechanism is mounted on the mounting base, and the two supporting side lugs are symmetrically welded to the outer wall of the mounting base.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] The pipe reel structure of this hydraulic testing equipment allows the servo motor to stop rotating when the test is completed or needs to be paused. At this time, the pipe will loosen due to gravity or external tension. The finger cylinder drives the two clamping claws to move towards the center and clamp the pipe. The clamping claws firmly hold the pipe, preventing it from slipping off the reel or getting tangled. This prevents the pipe from loosening and knotting, improves safety, and reduces manual intervention.

[0015] If the pipeline deviates in different directions or has inconsistent bending angles, the swing arm assembly is activated. The swing arm drives the mounting plate and the entire finger cylinder to move along the outer arc of the reel, so that the clamping claw is aligned with the optimal clamping point, improving clamping accuracy and stability, and adapting to pipelines with different orientations.

In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0025] This embodiment provides, for example Figures 1 to 4The illustrated hydraulic testing equipment includes a pipe reel structure comprising a hydraulic testing equipment housing 1. A pipe reel mechanism 2 for unwinding pipes during hydraulic testing is provided on one outer wall of the housing 1. The pipe reel mechanism 2 includes two symmetrically arranged support side lugs 5, a reel component 4 rotatably mounted between the two support side lugs 5, and a servo motor 6 mounted on the outer wall of one of the support side lugs 5 and driving the reel component 4 to rotate. A finger cylinder 13 is located directly in front of the reel component 4, and two clamping claws 14 are symmetrically arranged at the working end of the finger cylinder 13. The pipe is fed from the two clamping claws... The two gripping claws 14 pass through and wind up onto the reel 4. When the pipe does not need to be unwound, the finger cylinder 13 drives the two gripping claws 14 to move inward to grip the pipe, so that the two gripping claws 14 hold the pipe and prevent the pipe from falling off the reel 4 or becoming messy in a slack state. One of the supporting side ear plates 5 is also provided with a swing arm assembly for driving the finger cylinder 13 to swing in an arc along the outer circumference of the reel 4 to adjust the position and angle of the finger cylinder 13. When the swing arm assembly drives the finger cylinder 13 to move in an arc, the finger cylinder 13 grips the pipe and bends the pipe to lock the slack of the pipe.

[0026] In this embodiment, an extension mounting plate 7 is welded to the outer wall of one of the supporting side ear plates 5. The swing arm assembly includes a drive motor 8 mounted on the outer wall of the extension mounting plate 7, a swing arm 9 mounted on the output shaft of the drive motor 8, and a mounting plate 12 integrally connected to the free end of the swing arm 9. By driving the swing arm 9 to swing in an arc shape through the drive motor 8, the position of the finger cylinder 13 can be precisely adjusted to ensure the best clamping effect. This design enables the equipment to flexibly cope with pipeline management and processing tasks under various complex working conditions.

[0027] In this embodiment, the finger cylinder 13 is fixedly connected to the mounting plate 12 by bolts at its tail end, so that the position of the finger cylinder 13 can be adjusted when the drive motor 8 drives the rocker arm 9 to swing in an arc.

[0028] In this embodiment, the end of the finger cylinder 13 away from the mounting plate 12 is connected to another supporting side ear plate 5 through a positioning bracket to form a positioning mechanism for the finger cylinder 13 to swing and position in an arc shape in front of the reel 4.

[0029] In this embodiment, the positioning bracket includes a U-shaped positioning fork 11 welded to the opposite side of the two gripping claws 14 and located on the outer wall of the free end of the finger cylinder 13, and a positioning swing arm 10 welded to the back of the U-shaped positioning fork 11.

[0030] In this embodiment, the end of the positioning arm 10 away from the U-shaped positioning fork 11 is rotatably connected to another supporting side plate 5 via a pin 16.

[0031] In this embodiment, anti-slip rubber pads 15 are adhered to the inner walls of both gripping claws 14, and the two anti-slip rubber pads 15 are in frictional contact with the pipe.

[0032] In this embodiment, the outer wall of the hydraulic testing equipment housing 1 is bolted with a mounting base 3, the pipe reel mechanism 2 is mounted on the mounting base 3, and two supporting side lugs 5 are symmetrically welded to the outer wall of the mounting base 3.

[0033] Working principle

[0034] The hydraulic testing equipment features a pipe reel structure. The operator introduces the pipe required for the hydraulic test from the outside into the device. The pipe passes through the gap between the two clamping claws 14 and is then manually wound onto the reel 4. The servo motor 6 is started by the PLC in the external control cabinet, which drives the reel 4 to rotate slowly, assisting in the initial winding of the pipe. During the hydraulic test, as the hydraulic system operates, the pipe needs to be continuously pulled out for use. The reel 4, driven by the servo motor 6, rotates continuously and slowly, providing a certain tension to maintain the stable release of the pipe. The finger cylinder 13 is in a non-clamping state, meaning the two clamping claws 14 remain open, applying no pressure to the pipe to allow for free movement. The anti-slip rubber pad 15 does not contact the pipe at this time, only providing frictional assistance during subsequent clamping.

[0035] After the test is completed, the further release of the pipe needs to be stopped and it needs to be recycled or stored. The servo motor 6 rotates in reverse, driving the reel 4 to reel the remaining pipe to the surface. When the pipe is completely retracted, the PLC in the external control cabinet drives the finger cylinder 13 to start, driving the two clamping claws 14 to move centripetally and clamp the end of the pipe. The anti-slip rubber pad 15 is in close contact with the outer wall of the pipe to increase the clamping friction and prevent the pipe from slipping. At this time, the clamping claws 14 clamp the pipe to prevent the pipe from loosening and falling off due to equipment vibration or handling.

[0036] If the gripper 14 cannot be aligned with the pipe due to equipment layout, pipe length, or installation errors, the system can activate the swing arm assembly for automatic adjustment: the PLC drive motor 8 in the external control cabinet starts, driving the swing arm 9 to swing, thereby driving the finger cylinder 13 to move along the outer periphery of the reel 4 in an arc trajectory through the mounting plate 12. The U-shaped positioning fork 11 and the positioning swing arm 10 form a guide support to ensure that the movement path of the finger cylinder 13 is stable and reliable. The positioning swing arm 10 is connected to the support side ear plate 5 through the pin 16 to form a flexible rotation fulcrum.

[0037] Finally, even if the tightness of the pipe varies or there is a misalignment at different locations, the clamping claw 14 can accurately align and clamp the key parts of the pipe. After the clamping action is completed, all motors stop running and wait for the next test to begin.

[0038] It should be noted that, in this document, relational terms such as "one" and "two" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
