Description

Technical Field

[0001] The utility model belongs to the technical field of structural component detection, and particularly relates to a roller rod strength detection device. Background Technique

[0002] As a main component for transporting crucibles during the sintering of lithium-ion cathode materials, the strength of the roller rod is related to the normal operation of the entire production work. Due to the difficult installation and debugging, insufficient structural strength, and problems such as breakage, it is easy to cause crucible transportation failures, and even material dumping, which is difficult to clean up and causes the production line to stop.

[0003] Roller rod strength detection is an important link to ensure its reliable operation under complex working conditions such as high temperature and heavy load. In the laboratory, a flexural strength testing machine is usually used. The roller rod is placed on the supporting device of the testing machine, and a certain bending load is applied until the roller rod breaks. The maximum load at the time of fracture is recorded, and the flexural strength value is calculated. However, this method requires scrapping the roller rod, increasing production costs, and can only adopt sampling inspection, and it is impossible to complete qualified detection for each roller rod. Moreover, a single testing machine has a large investment and is generally immovable. Usually, about 660 roller rods need to be detected at a time on-site, and the handling difficulty is large, and the detection efficiency of the flexural strength testing machine is low. The common detection method in the existing actual production site is to manually apply a load to the roller rod using a material crucible, which has a large labor intensity.

[0028] Refer to Figures 1-5As shown in the figure, a roller strength detection device includes a lifting mechanism 1 and a weighing mechanism 2. The lifting mechanism 1 is arranged below the weighing mechanism 2. The lifting mechanism 1 is provided with a chassis 11, a test cylinder 12, guide rods 13, a lifting platform 14, slats 15, a regulating valve 16 and a control valve 17. The test cylinder 12 is vertically arranged at the center of the chassis 11. The lifting platform 14 is arranged on the test cylinder 12. The guide rods 13 are arranged between the lifting platform 14 and the chassis 11. The guide rods 13 are symmetrically arranged on the lifting platform 14 or the chassis 11, and corresponding guide holes 131 are provided on the chassis 11 or the lifting platform 14. The slats 15 are vertically arranged at both ends of the length of the lifting platform 14. The top surface of the slats 15 is provided with placing grooves 151 for supporting both ends of the roller 5. The control valve 17 is connected to the test cylinder 12 through the regulating valve 16, and the control valve 17 is externally connected to a gas source. The weighing mechanism 2 is provided with a frame 21, a lifting frame 22 and weights 23. The lifting frame 22 is arranged at the upper end of the frame 21 and is arranged opposite to the lifting platform 14. The weights 23 are placed in the lifting frame 22. Universal wheels 3 are arranged at the lower ends of both the chassis 11 and the frame 21. The lifting frame 22 presses on the surface of the roller 5 placed on the placing groove 151 to achieve strength detection.

[0029] Due to the large number of on-site equipment transformations, testing is carried out according to the maximum loading of the actual saggers, so as not to change the number and total weight of the weights 23. If necessary, the weight or number of the weights 23 can also be changed.

[0030] Usually, 3 saggers are arranged on one roller 5, and the span of each sagger is 3 - 5 rollers 5, usually 5 rollers. Corresponding to the slats 15, 5 placing grooves 151 or roller pairs 152 are provided for placing the rollers 5. Load detection is carried out according to the actual working state of the rollers 5. The weight of the weights 23 is the maximum loading weight of the corresponding number of saggers.

[0031] Place the roller 5 on the slats 15 to simulate the conveying track. Under the action of the test cylinder 12, the lifting platform 14 moves upward and abuts against the upper lifting frame 22. The lifting frame 22 and the weights 23 above it are equivalent to the loaded saggers. The roller 5 on the slats 15 jacks up the lifting frame 22 by a certain distance. If the roller 5 does not break, it is qualified. Lower the test cylinder 12, remove the lifting mechanism 1 or the weighing mechanism 2, take out the roller 5, and replace it with the next batch of rollers 5 to be detected.

[0032] The guide rods 13 are arranged around the chassis 11 and are connected to the corresponding guide holes 131 on the lifting platform 14. The guide rods 13 can also be arranged around the lower side of the lifting platform, and the guide holes 131 are arranged on the corresponding chassis 11, which play the same role.

[0033] Further, the lifting frame 22 is provided with a support frame 221, a support plate 222, a connecting frame 223 and a pressing plate 224. The support plate 222 is arranged on the relative outer extension of the support frame 221. The support plate 222 is mounted on the frame of the frame 21. The pressing plate 224 is arranged below the support frame 221 through the connecting frame 223. Oblique tie rods 225 are arranged at both ends of the pressing plate 224 and connected to the support frame 221. The pressing plate 224 presses on the surface of the roller rod 5 mounted on the placement groove 151 to realize strength detection.

[0034] The support frame 221 and the connecting frame 223 form the basic structure of the lifting frame 22. When not detecting, the support plate 222 supports the lifting frame 22 at the top of the frame 21. The pressing plate 224 simulates the sagger, and the weight 23 simulates the materials in the sagger. The oblique tie rods 225 strengthen the connection strength between the support frame 221 and the pressing plate 224 and prevent interference with the frame 21 during lifting.

[0035] Further, a weight frame 226 is arranged on the support frame 221, and the weight 23 is arranged in the weight frame 226.

[0036] The weight frame 226 improves the stability of the placement of the weight 23. Corresponding to the weight 23, the weight frame 226 can also be provided with fixing parts or elastic clamping parts to improve stability and prevent tipping during detection.

[0037] Further, the placement groove 151 is arc-shaped or V-shaped, and there are 3 - 5 pairs of the placement grooves 151.

[0038] The placement groove 151 improves the stability of the roller rod 5 and maintains the spacing.

[0039] Further, roller pairs 152 are oppositely arranged on the opposite sides of the two ends of the placement groove 151 that face away from each other.

[0040] On the one hand, the rollers facilitate the adjustment of the roller rod 5. On the other hand, they simulate the actual work. In the actual installation of the roller rod 5, rollers for assisting the rotation of the roller rod 5 are also provided.

[0041] Further, the spacing S between adjacent placement grooves 151 or roller pairs 152 is 81 mm.

[0042] Simulate the actual working scenario.

[0043] Further, the length L of the pressing plate 224 parallel to the length direction of the roller rod 5 is 1320 mm.

[0044] Simulate the maximum sagger load capacity in actual work.

[0045] Further, a positioning component 4 is provided between the pressing plate 224 and the lifting frame 22. The positioning component 4 is provided with a positioning rod 41, a sleeve 42, a plug rod 43 and a jack 44. The positioning rod 41 is fixed at the centers on both sides of the length of the pressing plate 224. The sleeve 42 is arranged at the upper end of the positioning rod 41. The jack 44 is correspondingly arranged on the lifting frame 22 with respect to the sleeve 42. The plug rod 43 passes through the jack 44 and is connected to the sleeve 42.

[0046] The positioning component 4 ensures the alignment of the lifting mechanism 1 and the weight mechanism 2, so that the pressing plate 224 is located at the center of the roller rod 5.

[0047] Further, a limiting end head 45 is arranged at the upper end of the plug rod 43.

[0048] The limiting end head 45 avoids the risk of the plug rod 43 falling off.

[0049] Further, a limiting plate or a limiting rod 142 is arranged at one end of the lifting table 14. The limiting rod 142 corresponds to the placing groove 151 or the roller pair 152 one by one.

[0050] The limiting plate or the limiting rod 142 makes the roller rods 5 arranged neatly on the slats 15.

[0051] Combined with Figures 1-2 , the present utility model proposes an implementation method of a roller rod strength detection device, including the following specific operation steps:

[0052] Step 1: The compressed air of the air compressor passes through the regulating valve 16 and the manual control valve 17 and enters the test cylinder 12. The weights 23 corresponding to the weight are placed in the lifting frame 22.

[0053] Step 2: Place the roller rod 5 to be tested for strength on the slats 15.

[0054] Step 3: Push the weight mechanism 2 above the lifting mechanism 1, align them, and insert the plug rod 43 into the sleeve 42.

[0055] Step 4: Turn the manual reversing valve, and the test cylinder 12 drives the roller rod 5 to rise.

[0056] Step 5: The roller rod 5 rises to lift the pressing plate 224 with the weights 23. If the roller rod 5 is not broken, the strength of this group of roller rods 5 is qualified; otherwise, the strength of the roller rod 5 is insufficient and unqualified.

[0057] Step 6: Turn the manual reversing valve, and the test cylinder 12 drives the roller rod 5 to descend.

[0058] Step 7: The lifting frame 22 drives the pressing plate 224 to fall back onto the frame 21, and the strength test is over.

[0059] Step 8: Pull out the insertion rod 43, push out the weight mechanism 2 or the lifting mechanism 1, remove the roller 5 on the slat 15, replace the roller 5 to be detected, and perform the next detection operation.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
