[0016] 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.

[0017] Example: Figure 1-3 As shown, this utility model provides an electric roller load testing device, including a base plate 1. Vertically arranged upright plates 11 are provided at both ends of the upper surface of the base plate 1. A placement groove 12 is formed through the upper ends of the two upright plates 11. A fixing plate 13 is fixedly provided on the opposite side of the two upright plates 11 near the placement groove 12. The middle end of the fixing plate 13 is connected through the placement groove 12. The fixing plate 13 is circular and has multiple first toothed plates 14 arranged in a ring. One side of each first toothed plate 14 slides through the fixing plate 13. The inner wall is provided with a rotatable gear ring 18. A first rotating rod 16 is provided on the gear ring 18 near each first tooth plate 14. A first gear 15 is fixed on the first rotating rod 16 and meshes with the gear ring 18 and the first tooth plate 14. A positioning block 17 is fixed at one end of the first tooth plate 14 inside the fixed plate 13. A groove 3 is provided through the inside of the bottom plate 1. Moving plates 33 are slidably provided at both ends of the groove 3 and the two moving plates 33 are respectively fixed at the lower end of the upright plate 11. A support plate 42 is provided directly above the middle end of the upper surface of the bottom plate 1.

[0018] A drive motor 23 is fixedly installed on the side of the fixed plate 13 away from the upright plate 11, near one of the first rotating rods 16. The output end of the drive motor 23 is connected to the first rotating rod 16. The drive motor 23 provides power for the rotation of the first rotating rod 16, so that the rotation of the first rotating rod 16 can drive other corresponding structures to work, making it convenient for the staff to operate.

[0019] One end of the rotating rod near the drive motor 23 passes through the fixed plate 13 and is fixedly equipped with a worm gear 21. A worm 22 is meshed on the worm gear 21. The output end of the drive motor 23 is coaxially fixedly mounted on the worm 22. The worm 22 drives the worm gear 21 to rotate the first rotating rod 16. Since the worm 22 creates a self-locking mechanism when driving the worm gear 21 to rotate, this prevents the gear ring 18, the first gear 15, and the first rotating rod 16 from reversing. A protective cover 2 is fixedly installed on the outer wall of the fixed plate 13 near the worm gear 21 and the worm 22. The worm gear 22 is rotatably mounted inside the protective cover 2. The protective cover 2 provides support and protection for the rotation of the worm wheel 21 and the worm gear 22, preventing external influences from affecting the normal rotation of the worm wheel 21 and the worm gear 22. A limiting rod 19 is fixedly mounted on the back of the positioning block 17. The end of the limiting rod 19 away from the positioning block 17 is movably inserted into the placement groove 12. The limiting rod 19 mainly limits the movement of the positioning block 17, allowing it to move according to the set movement trajectory, preventing deviation from affecting the clamping and positioning of the shafts at both ends of the electric drum.

[0020] A second gear 31 is rotatably mounted at the middle end inside the groove 3. Two second toothed plates 32 are meshed on the second gear 31 and arranged diagonally. The end of the second toothed plate 32 away from the drive gear is fixedly mounted on the moving plate 33. A first electric push rod 34 is fixedly inserted into one end of the base plate 1. The output end of the first electric push rod 34 is fixedly mounted on the adjacent moving plate 33. When the first electric push rod 34 pushes the moving plate 33 to move, since the two second toothed plates 32 are meshed on the second gear 31, when the first electric push rod 34 pushes one of the moving plates 33 to move, the other moving plate 33 will move towards or away from the other moving plate, controlling the two upright plates 11 to move closer to or away from the electric drum at the same time.

[0021] A long plate 4 is fixedly mounted on the upper surface of the base plate 1. Two symmetrically arranged second electric push rods 41 are fixedly mounted on the upper surface of the long plate 4. The output end of the second electric push rod 41 is fixedly mounted on the support plate 42. The second electric push rod 41 controls the support plate 42 to move up and down to support the electric roller. It also makes it convenient to remove the support for the electric roller after the subsequent installation of the upright plate 11 on the electric roller, so that the electric roller can rotate.

[0022] Working principle: During use, the operator places the electric roller to be tested directly on the two trays 42, such as... Figure 1As shown, the first electric push rod 34 then pushes one of the moving plates 33 toward the second gear 31. At this time, the two second gear plates 32 meshing on the same second gear 31 will move toward each other simultaneously. When the first electric push rod 34 pushes one of the moving plates 33 toward the second gear 31, the other moving plate 33 will move toward the second gear 31 at the same time. At this time, the upright plates 11 fixed on the two moving plates 33 will approach the two ends of the electric drum at the same time, and under the support of the support plate 42, the two ends of the electric drum will pass through the middle end of the placement groove 12 and the fixed plate 13. Then, the drive motor 23 will drive the worm gear 22 to drive the worm wheel 21 to rotate. At this time, the worm wheel 21 will drive the first rotating rod 16 to rotate. At this time, the first gear 15 fixed on the first rotating rod 16 will simultaneously drive the meshing first gear plate 14 and the gear ring. When the drive motor 18 operates, the first toothed plate 14 drives the positioning block 17 at the end to approach the shaft of the electric drum at the middle end of the fixed plate 13. When the toothed ring 18 rotates, it drives the other meshing first gear 15 to rotate, so that the first gear 15 drives the meshing first toothed plate 14 to drive the positioning block 17 fixed at the end to clamp towards the shaft of the electric drum. Therefore, when the drive motor 23 is working, it can directly drive multiple positioning blocks 17 to clamp the end of the electric drum simultaneously, so that the electric drum can be fixed to both ends of the vertical plate 11. At this time, the second electric push rod 41 controls the two support plates 42 to move down, canceling the support for the electric drum, energizing the electric drum, and driving the electric drum to rotate. This process is the drive motor inside the electric drum driving the electric drum to rotate. The test is carried out by using magnetic powder brakes, eddy current brakes, etc. These can precisely adjust the load torque applied to the electric drum by controlling the current, etc., to simulate different working load conditions.

[0023] After the test is completed, the second electric push rod 41 pushes the support plate 42 upward to support the electric drum. The drive motor 23 drives in the opposite direction, controlling multiple positioning blocks 17 to move away from the end of the electric drum and canceling their fixation. The first electric push rod 34 controls the moving plate 33 to move away from the second gear 31. At this time, the two upright plates 11 will directly detach from the end of the electric drum, making it convenient for workers to remove them directly.

[0024] All standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
