Description

Technical Field

[0001] This utility model relates to the field of energy storage battery testing technology, specifically to an energy storage battery handle pull force testing device. Background Technology

[0002] In the safety testing of energy storage batteries, the maximum tensile force that the battery handle can withstand has always been an important indicator for measuring the safety of the battery in actual use. Especially now, with the booming development of mobile energy storage batteries, corresponding standards for handle strength have emerged one after another. The existing methods for testing handle strength are relatively traditional, which use manual lifting and apply gravity to the energy storage battery to test the strength of the battery handle.

[0003] Manual testing methods have many safety hazards and drawbacks. The process of manually lifting the energy storage battery may cause many safety hazards. At the same time, the process of applying gravity will further increase the load on the personnel and increase the risk of testing. In the long run, it will cause occupational diseases such as lumbar strain for the test personnel. Moreover, it cannot accurately test the limit value of the handle pulling force. The limitations are very significant and the adaptability is poor. Therefore, there is a need for a handle pulling force testing device suitable for most energy storage battery products to solve the many drawbacks of traditional handle pulling force testing.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention discloses a battery handle pull force testing device, comprising a base plate 1, a beam frame 8, a crossbeam 14, and an adjusting rod 3. The base plate 1 is installed on the beam frame 8. The crossbeam 14 and the adjusting rod 3 are arranged parallel to each other inside the beam frame 8, one above the other. A tension sensor 13 is installed between the crossbeam 14 and the adjusting rod 3. Lifting mechanisms for adjusting the height of the crossbeam 14 and the adjusting rod 3 are installed at both ends of the crossbeam 14. A host 12 for controlling the lifting mechanism and displaying the pull force is provided on one side of the beam frame 8. Multiple adjusting sleeves 4 are sleeved on the adjusting rod 3. Each adjusting sleeve 4 has a hook 5 at one end. Each hook 5 has a connecting groove at its vertical end. Each connecting groove has a connecting post 16. One end of each connecting post 16 is installed on the adjusting sleeve 4. A locking mechanism for positioning the hook 5 is installed in the vertical section of each hook 5. An adjustable pressing mechanism is installed on the base plate 1.

[0028] The main unit is equipped with a power switch, an emergency stop switch, a human-machine interface touch screen, a PLC controller, and a main power switch. The PLC controller can feed back the data detected by the tension sensor and drive the servo motor to move to the maximum tension value to be detected. The human-machine interface touch screen can display the tension value and control the device. The power switch, emergency stop switch, and main power switch can control the opening and closing of the device, which increases safety.

[0029] The main unit has four rectangular casters (not shown) mounted on its bottom surface. These casters allow the main unit to be moved to a distance for remote operation.

[0030] In this embodiment, the locking mechanism includes a positioning post 21, a grip rod 19, and a compression spring 20. The bend of the hook 5 is provided with a parallel surface, and a first positioning port that penetrates the hook 5 is provided perpendicularly on the parallel surface. The center of the connecting post 16 is provided with a second positioning port that penetrates the connecting post 16 and the adjusting sleeve 4. The bottom surface of the adjusting rod 3 is provided with multiple positioning grooves 18. One end of the positioning post 21 passes through the first positioning port and the second positioning port and is inserted into the corresponding positioning groove 18. The other end is fixedly connected to the grip rod 19. The compression spring 20 is sleeved on the positioning post 21. One end of the compression spring 20 is installed on the parallel surface, and the other end is installed on the grip rod 19.

[0031] In this embodiment, the outer ring surface of the connecting column 16 is provided with an annular connecting groove 22, and the inner ring surface of the connecting groove is provided with a limiting ring at the position opposite to the limiting groove 22. The limiting ring is slidably disposed in the limiting groove 22.

[0032] In this embodiment, the pressing mechanism includes an adjustable lifting pressure rod 7, a fine-tuning pressure block 10, a longitudinal plate 9, a screw, and a handwheel 11. The adjustable lifting pressure rod 7 is installed on the base plate 1, and the longitudinal plate 9 is installed at the end of the adjustable lifting pressure rod 7 away from the base plate 1. The other end of the longitudinal plate 9 is provided with a screw hole, and the screw is threaded into the screw hole. One end of the screw is fixedly connected to the fine-tuning pressure block 10, and the other end is fixedly connected to the handwheel 11. The adjustable lifting pressure rod is a rectangular telescopic rod with a locking bolt, which can quickly change the height of the longitudinal plate and position it.

[0033] In this embodiment, the lifting mechanism includes a servo motor 23, a synchronous belt 24, multiple lead screws 17, multiple moving platforms 15, and synchronous pulleys 25. A U-shaped groove 2 is provided on the inner side of the beam frame 8. The lead screws 17 are located on both sides of the U-shaped groove 2. An installation groove is provided on the top surface of the U-shaped groove 2, opposite to one side of the lead screw 17. The servo motor 23 is installed in the installation groove and fixedly connected to one side of the lead screw 17 via a coupling. The synchronous pulleys 25 are all installed on the lead screws 17. The synchronous belt 24 is coiled around the multiple synchronous pulleys 25. The moving platform 15 is sleeved on the lead screw 17 and threadedly connected to it. Both ends of the crossbeam 14 are fixedly connected to the moving platform 15. The width of the moving platform 15 matches the width of the U-shaped groove 2, ensuring that the moving platform can only move stably up and down along the U-shaped groove, thus increasing stability.

[0034] In this embodiment, a first bearing is embedded in one side of the U-shaped groove 2, and a second bearing is embedded in the other side of the U-shaped groove 2. Both ends of the lead screw 17 on one side are installed in the inner ring of the first bearing, and the end of the lead screw 17 on the other side away from the servo motor 23 is installed in the inner ring of the second bearing. The lead screw can be positioned by the first bearing and the second bearing, thus avoiding the swinging of the lead screw.

[0035] In this embodiment, the cross-sections of the positioning groove 18, the first positioning port, the second positioning port, and the positioning post 21 are all polygonal, which can position the hook circumferentially and avoid lateral movement along the adjusting rod.

[0036] In this embodiment, a groove 6 is provided on one side of the hook. After the hook is fitted onto the handle, the handle can enter the groove, which adds a limiting function and prevents the handle from detaching from the hook.

[0037] When using, first adjust the distance between the hooks according to the length of the handle on the energy storage battery. When adjusting, pull down the positioning pin by holding the rod until the positioning pin moves out of the positioning slot. At this time, the adjusting sleeve can drive the hook to move laterally along the adjusting rod until the hook is smoothly put on the handle of the energy storage battery. After releasing the grip, the return of the compression spring can drive the positioning pin to insert into the corresponding positioning slot, thereby positioning the adjusted sleeve and hook after movement.

[0038] Since some energy storage batteries have handles that are not horizontally positioned but vertically positioned on the top surface of the battery, this device can also be adapted to such energy storage batteries. During operation, by pulling down the positioning pin again by holding the lever until the positioning pin moves out of the second positioning hole, the hook can rotate around the limiting ring until the hook is horizontally facing the vertically positioned handle. In this state, the adjusting sleeve can also move along the adjusting rod. After moving inward, the hook can be smoothly put on the handle.

[0039] After the energy storage battery is hung on the hook, the height of the adjustable lifting lever can be changed, and the vertical plate can be moved up and down until the vertical plate moves to the upper surface of the energy storage battery. By rotating the handwheel, the screw can be moved down until the fine adjustment block is in contact with the upper surface of the energy storage battery. The fine adjustment block can apply a limit function to the energy storage battery.

[0040] After the above is completed, the servo motor is started, which drives the lead screw to rotate synchronously through the synchronous belt and synchronous pulley. The rotation of the lead screw drives the moving platform and crossbeam. The movement of the crossbeam drives the tension sensor, adjusting rod, adjusting sleeve and hook. During the upward movement of the hook, due to the obstruction of the fine adjustment block, the handle has an outward pulling force. The value of this pulling force is displayed on the host through the tension sensor.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
