Description

Technical Field

[0001] This utility model relates to the technical field of hose comprehensive performance testing equipment, specifically a hose comprehensive performance testing machine. Background Technology

[0002] To ensure the structural strength and application safety of flexible hoses, it is often necessary to conduct comprehensive performance tests on the hoses. This necessitates the use of flexible hose comprehensive performance testing equipment. Utility model patent application number CN201320560533.6 discloses a brake hose bending performance testing device, including a base plate, baffles, a core disc, hose clamps, and handles. The core disc is centrally located on the base plate, and baffles on both sides of the core disc define the bending path of the brake hose. During testing, the handles are connected to both ends of the brake hose using hose clamps. This allows for a direct assessment of whether the hardness of the brake hoses used in railway vehicles meets the standards before installation, preventing their use on trains. Standardized brake hoses ensure proper attachment and detachment, preventing hose stretching at the source, improving hose operability, and reducing vehicle spare parts consumption. However, according to publicly available technical solutions, existing hose performance testing equipment has several drawbacks. First, it cannot automatically calibrate the pressure sensor during tensile strength testing, leading to errors in test results and compromising accuracy. Second, when using weights to calibrate the pressure sensor, if the hose breaks, the weights may fall and injure personnel or equipment, jeopardizing safety.

[0003] Therefore, how to design a comprehensive performance testing machine for hoses has become a problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hose comprehensive performance testing machine to solve the problems mentioned in the background technology. This utility model is reasonably designed, convenient to use, and suitable for comprehensive performance testing of hoses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hose comprehensive performance testing machine, comprising a frame and an electric telescopic rod, wherein a detection component is installed on the electric telescopic rod, the detection component including a sensor and a clamp; a pulling component is installed on the frame, the pulling component including a pulley and a weight; a buffer component is installed on the frame, the buffer component including a sliding rod and a spring; a bending component is installed on the frame, the bending component including a torsion bar and a frame; a drive component is installed on the torsion bar, the drive component including a motor and a reducer; and a pressure bending component is installed on the frame, the pressure bending component including a support roller and a pressure roller.

[0006] Furthermore, the bottom end of the electric telescopic rod is bolted to the bottom of the frame, the bottom of the sensor is bolted to the top of the electric telescopic rod, and the clamp is bolted to the top of the sensor.

[0007] Furthermore, the pulley is bolted to the top of the frame, the pulley is located at the top of the electric telescopic rod, and the bottom end of the sliding rod is bolted to the bottom of the frame.

[0008] Furthermore, the sliding rod is located on one side of the electric telescopic rod, the pulley is located at the top between the sliding rod and the electric telescopic rod, the sliding rod and the electric telescopic rod are each corresponding to a sliding roller, the bottom end of the spring is welded to the frame, and the spring is sleeved on the outside of the sliding rod.

[0009] Furthermore, the weights are arranged at the bottom of the frame, and the weights have grooves with an inner diameter equal to the diameter of the sliding rod.

[0010] Furthermore, both ends of the torsion bar are mounted on the top of the frame via bearings, and the frame is bolted to the inside of the frame, with the frame located at the bottom of the torsion bar.

[0011] Furthermore, the reducer is bolted to the top of the frame, the motor is bolted to one side of the reducer, the drive shaft of the reducer is keyed to the output shaft of the motor, and the output shaft of the reducer is keyed to one end of the torsion bar.

[0012] Furthermore, the support roller is bolted to the inside of the frame, the pressure roller is placed inside the frame, a display is bolted to the frame, a switch assembly is bolted to the display, the switch assembly is connected to the motor and the display via wires, and the display is connected to the sensor via wires.

[0013] Beneficial effects: 1. When using this hose comprehensive performance testing machine, one end of the hose is fixed with a clamp, and the other end of the hose is bound with a rope. The other end of the rope is then passed over a pulley, and a weight is placed on the outside of the sliding rod through a groove. The other end of the rope is then bound to the weight. The weight is used to pull the rope, which in turn pulls the top of the hose through the pulley, thus causing the sensor to experience an upward pulling force. The display shows the pulling force value sensed by the sensor and verifies it against the weight of the weight. This effectively verifies the accuracy of the sensor, avoiding inaccurate results in the hose tensile test and ensuring the accuracy of the hose tensile test.

[0014] 2. When using this hose comprehensive performance testing machine, if the hose breaks, the rope loosens, or the clamp loosens during the calibration of the sensor's tensile force using weights, the weight will fall rapidly downwards through the slide groove on the outside of the slide rod. A spring will then cushion the impact, preventing the weight from directly impacting the bottom of the frame and ensuring the safety of both the weight and the frame. Simultaneously, the slide rod and slide groove limit the movement of the weight, preventing it from hitting nearby personnel or equipment, ensuring their safety. After calibration, the other end of the hose is tied to the top of the slide rod with a rope. By retracting the electric telescopic rod, the tensile force on the hose is gradually increased to test its tensile strength. The hose is then passed through the frame and fixed to the torsion bar. The motor drives the torsion bar to rotate via a reducer, causing the hose to bend, thus testing its bending effect. Finally, the hose is placed on top of the support roller, and pressure rollers of different weights are placed on the hose to test its flexural strength. This allows for comprehensive performance testing of the hose.

[0015] 3. This hose comprehensive performance testing machine is reasonably designed, highly efficient and convenient to use, and suitable for comprehensive performance testing of hoses. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a hose comprehensive performance testing machine, including a frame 1 and an electric telescopic rod 2. A detection component is installed on the electric telescopic rod 2, including a sensor 3 and a clamp 4. A pulling component is installed on the frame 1, including a pulley 5 and a weight 8. A buffer component is installed on the frame 1, including a sliding rod 6 and a spring 7. A bending component is installed on the frame 1, including a torsion bar 10 and a frame 11. A drive component is installed on the torsion bar 10, including a motor 12 and a reducer 13. A pressure bending component is installed on the frame 1, including a support roller 14 and a pressure roller 15. The bottom end of the electric telescopic rod 2 is bolted to the bottom of the frame 1. The bottom of the sensor 3 is bolted to the top of the electric telescopic rod 2. The clamp 4 is bolted to the top of the sensor 3. The pulley 5 is bolted to the top of the frame 1, located at the top of the electric telescopic rod 2. The bottom end of the sliding rod 6 is bolted to the bottom of the frame 1. Installed at the bottom of frame 1, the support roller 14 is bolted to the inside of frame 1, and the pressure roller 15 is placed inside frame 1. A display 16 is bolted to frame 1, and a switch assembly is bolted to display 16. The switch assembly is connected to motor 12 and display 16 via wires. Display 16 is connected to sensor 3 via wires. In use, one end of the hose is fixed with clamp 4, and the other end of the hose is tied with a rope. The other end of the rope is then passed around pulley 5. A weight 8 is placed on the outside of slide rod 6 through groove 9, and the other end of the rope is tied to the weight 8. The rope is pulled by the weight 8, and the rope pulls the top of the hose through the pulley, thus applying an upward force to sensor 3. Display 16 shows the force value sensed by sensor 3 and verifies it against the weight 8. This effectively verifies the accuracy of sensor 3, avoids inaccurate results of hose tension tests, and ensures the accuracy of hose tension detection.

[0024] In this embodiment, the sliding rod 6 is located on one side of the electric telescopic rod 2, and the pulley 5 is located at the top between the sliding rod 6 and the electric telescopic rod 2. The sliding rod 6 and the electric telescopic rod 2 each correspond one-to-one with the sliding roller 5. The bottom end of the spring 7 is welded to the frame 1, and the spring 7 is sleeved on the outside of the sliding rod 6. The weights 8 are arranged at the bottom of the frame 1, and each weight 8 has a groove 9 with an inner diameter equal to the diameter of the sliding rod 6. Both ends of the torsion bar 10 are mounted on the top of the frame 1 via bearings. The frame 11 is bolted to the inside of the frame 1, and the frame 11 is located at the bottom of the torsion bar 10. The reducer 13 is bolted to the top of the frame 1, and the motor 12 is bolted to one side of the reducer 13. The drive shaft of the reducer 13 is keyed to the output shaft of the motor 12, and the output shaft of the reducer 13 is keyed to one end of the torsion bar 10. During use, when using the weights 8 to verify the tension of the sensor 3, if the flexible tube breaks... When the rope is released or the clamp 4 is released, the weight 8 will fall rapidly downwards through the groove 9 on the outside of the slide rod 6. The spring 7 will then cushion the fall, preventing the weight 8 from directly impacting the bottom of the frame 1, thus ensuring the safety of the weight 8 and the frame 1. At the same time, the slide rod 6 and the groove 9 will limit the movement trajectory of the weight 8, preventing it from hitting nearby personnel or equipment, thus ensuring the safety of personnel and equipment. After the calibration work is completed, the other end of the hose is tied to the top of the slide rod 6 with a rope. By retracting the electric telescopic rod 2, the tension on the hose is gradually increased to test the tensile strength of the hose. The hose is then passed through the frame 11 and fixed to the torsion bar 10. The motor 12 drives the torsion bar 10 to rotate through the reducer 13, thereby causing the hose to bend, thus testing the bending effect of the hose. The hose is then placed on top of the support roller 14, and pressure rollers 15 of different weights are placed on the hose to test the bending resistance of the hose, thus enabling comprehensive performance testing of the hose.

[0025] This hose comprehensive performance testing machine provides power to all electrical equipment via an external power supply. In use, one end of the hose is fixed with clamp 4, and the other end is bound with a rope. The other end of the rope is then passed over pulley 5. A weight 8 is placed on the outside of slide rod 6 via groove 9, and the other end of the rope is bound to the weight 8. The rope is then pulled by the weight 8, causing the rope to pull the top of the hose through the pulley, thus applying an upward force to sensor 3. The display 16 shows the tension value sensed by sensor 3 and verifies it against the weight 8. This effectively verifies the accuracy of sensor 3, preventing inaccurate results in the hose tension test and ensuring accurate hose tension detection. However, if the hose breaks, the rope loosens, or clamp 4 loosens during the verification of sensor 3's tension using weight 8, the weight 8 will... The slide chute 9 falls rapidly downwards outside the slide rod 6, and the spring 7 provides cushioning to prevent the weight 8 from directly impacting the bottom of the frame 1, ensuring the safety of the weight 8 and the frame 1. At the same time, the slide rod 6 and slide chute 9 limit the movement trajectory of the weight 8 to prevent it from hitting nearby personnel or equipment, ensuring the safety of personnel and equipment. After completing the calibration work, the other end of the hose is tied to the top of the slide rod 6 with a rope. By retracting the electric telescopic rod 2, the tension on the hose is gradually increased to test the tensile strength of the hose. The hose is then passed through the frame 11 and fixed to the torsion bar 10. The motor 12 drives the torsion bar 10 to rotate through the reducer 13, thereby causing the hose to bend, thus testing the bending effect of the hose. The hose is then placed on top of the support roller 14, and pressure rollers 15 of different weights are placed on the hose to test the bending resistance of the hose, thus enabling comprehensive performance testing of the hose.
