Description

Technical Field

[0001] The utility model belongs to the technical field of forklift drive axle detection devices, and particularly relates to a forklift drive axle strength detection device. Background Technique

[0002] As a key component of a forklift, the forklift drive axle mainly undertakes the functions of reducing the rotational speed, increasing the torque, and changing the power transmission direction. Detecting the forklift drive axle can timely discover potential faults, prevent sudden equipment damage, and ensure the safe and efficient operation of the forklift. Currently, the detection methods for forklift drive axles include various methods such as visual inspection, performance testing, and component flaw detection, including methods for testing or analyzing the drive axle material by measuring its chemical or physical properties; however, during the detection process of some existing detection devices for forklift drive axles, it is difficult to flexibly move the position of the forklift drive axle, resulting in the detection personnel being able to only detect a single part of the drive axle. If other parts need to be detected, the position of the drive axle needs to be frequently adjusted, which not only consumes time and effort but also easily results in detection blind spots, causing some faults to not be discovered in time, increasing the safety hazards of forklift operation, and reducing the detection efficiency and accuracy.

[0062] A specific application of this embodiment is as follows: When using this device, first place the forklift drive axle to be detected on the top of the placement table 124, and then fix the forklift drive axle through the clamping part 2. After fixing the forklift drive axle, conduct an impact test on the material specimen of the forklift drive axle through the pendulum impact device 21 to measure the impact absorption work of the material in order to evaluate the toughness and anti-brittle fracture ability of the material. During the detection process, when it is necessary to move the position of the forklift drive axle to detect different parts of the forklift drive axle, start the motor 121. The motor 121 drives the threaded rod 122 to rotate. When the threaded rod 122 rotates, it drives the internally threaded block 123 to axially move under the restriction of the first limiting groove 131. The first limiting groove 131 limits the internally threaded block 123 to prevent the internally threaded block 123 from rotating along with the rotation of the threaded rod 122. When the internally threaded block 123 moves, it drives the placement table 124 to move, and then drives the forklift drive axle to move through the placement table 124. When the placement table 124 moves, it drives the T-shaped slider 133 to slide in the T-shaped groove 132, thereby limiting the moving position of the placement table 124 through the T-shaped groove 132 and the T-shaped slider 133 to ensure the stability of the placement table 124 during the moving process.

[0063] When the forklift drive axle is placed on the top of the placement table 124 and fixed through the clamping part 2, first start the electric push rod 233. The electric push rod 233 drives the first slider 231 to slide on the support rod 221. When the first slider 231 slides, it drives the Z-shaped plate 241 to rotate around the axis of the fixed rod 223 through the connecting plate 242 between the first slider 231 and the Z-shaped plate 241. When the Z-shaped plate 241 rotates, it drives the second slider 232 to slide on the support rod 221 through the connecting plate 242 between the Z-shaped plate 241 and the second slider 232, so that the first slider 231 and the second slider 232 move synchronously. When the first slider 231 and the second slider 232 move, they drive the clamping plates 244 to move respectively. When the output shaft of the electric push rod 233 extends, the first slider 231 and the second slider 232 move away from each other, so that the two clamping plates 244 move away from each other to loosen the clamping of the forklift drive axle. When the output shaft of the electric push rod 233 contracts, the first slider 231 and the second slider 232 move closer to each other, so that the two clamping plates 244 move closer to each other to clamp and fix the forklift drive axle. When the clamping plates 244 move, they are slidably connected with the second limiting groove 243, so that the clamping plates 244 are clamped and fixed through the second limiting groove 243 to keep the moving process of the clamping plates 244 stable.
