Description

Technical Field

[0001] This invention belongs to the field of forklift inspection technology, specifically referring to a forklift counterweight detection device. Background Technology

[0002] Forklifts are industrial handling vehicles, referring to various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transportation of palletized goods. They are widely used in ports, railway stations, airports, freight yards, factory workshops, warehouses, distribution centers, and other fields.

[0003] Forklifts typically handle heavy loads, so counterweights are needed to maintain their balance during use. These counterweights are usually designed by technicians through calculations. However, in practice, forklifts operate under a variety of conditions, and existing counterweight testing methods often cannot effectively simulate the actual working conditions of forklifts. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a forklift counterweight detection device that can simulate the real working conditions of a forklift in actual operation and detect the counterweight of the forklift more accurately.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a forklift counterweight detection device, including a base, a detection plate and a gravity simulation mechanism. The detection plate is hinged to the top of the base, and the gravity simulation mechanism is slidably disposed in front of the base.

[0006] Furthermore, the base includes a support mechanism and an adjustment mechanism, with the adjustment mechanism located in front of the support mechanism.

[0007] Furthermore, the support mechanism includes a base plate, support rods, support hydraulic rods, a ramp, and a reserved groove. The support rods are arranged in a linear array on one side of the top of the base plate, the support hydraulic rods are arranged in a linear array on the other side of the top of the base plate, the ramp is located on the side of the base plate away from the adjustment mechanism, and the reserved groove is opened on the top wall of the ramp.

[0008] Furthermore, the adjustment mechanism includes an adjustment chamber, a reserved opening, a slide groove, and a reset block. The adjustment chamber is located in front of the base plate and is hollow. The reserved opening is located on the top wall of the adjustment chamber, the slide groove is located on the front wall of the adjustment chamber, and the reset blocks are symmetrically arranged inside the adjustment chamber. The side wall of the reset block closest to the other reset block is inclined.

[0009] Furthermore, the detection plate includes a support plate, the top wall of which has an adjustment groove, a cover plate above the adjustment groove, a bidirectional screw rotatably mounted inside the adjustment groove, the two ends of the bidirectional screw having opposite threads, the bidirectional screw being electrically controlled, symmetrically arranged limiting telescopic rods on the side wall of the support plate, the ends of the limiting telescopic rods rotatably mounted on the side wall of the support plate, a limiting rod between the ends of the limiting telescopic rods, the limiting rod being located in a reserved groove, the bottom wall of the support plate having a linear array of flipping grooves, one side of the support plate being hinged to the top of the support rod, and the top of the support hydraulic rod being located inside the flipping groove.

[0010] Furthermore, a measuring mechanism is symmetrically and slidably arranged within the adjustment groove. The measuring mechanism includes a sliding plate, a gravity detection module, and a screw hole. The sliding plate is slidably disposed within the adjustment groove, the gravity detection module is symmetrically disposed on the top of the sliding plate, and the screw hole is formed on the sliding plate, engaging with the threads at both ends of a bidirectional screw. By controlling the rotation of the bidirectional screw, the distance between the measuring mechanisms can be adjusted to accommodate forklifts with different wheelbases. The gravity detection module can measure the pressure applied to each wheel separately. This type of device is existing technology and will not be described in detail here.

[0011] Furthermore, a control mechanism is slidably provided in the slide groove. The control mechanism includes a limiting plate and an adjusting screw. The limiting plate is slidably disposed in the slide groove, and the adjusting screw is rotatably disposed on the side of the limiting plate near the support mechanism. The adjusting screw is disposed inside the adjusting chamber, and the adjusting screw is electrically controlled.

[0012] Furthermore, the gravity simulation mechanism includes an adjusting slider and a pressure plate. The adjusting slider includes a slider one and a slider two. Slider one is located above slider two. Slider one has symmetrical sliding holes at both ends. Slider two has bosses at the four corners of its top wall. A sliding rod is also provided above slider two. The sliding rod passes through the sliding holes and is located between the bosses. A spring is provided between one side wall of slider and the boss. The spring is sleeved on the outside of the sliding rod. Slider two has a threaded hole two that engages with the adjusting screw. The top wall of slider one is attached to the top wall of the adjusting chamber. The bottom wall of slider two is attached to the bottom wall of the adjusting chamber. A pressure hydraulic rod is provided on the top wall of slider one. A ball head is provided on the top wall of the pressure hydraulic rod.

[0013] Furthermore, the pressure plate includes a plate body, a groove, and a support groove. The groove is located at the bottom of the plate body, the ball head is located in the groove, and the support groove is symmetrically opened on the bottom wall of the plate body.

[0014] The beneficial effects of this invention using the above structure are as follows: This solution provides a forklift counterweight detection device. The bidirectional screw can control the measuring mechanisms to move closer to or further away from each other, adjusting the distance to adapt to the wheelbase of different forklift specifications. The gravity detection module can measure the pressure data of each of the four forklift wheels and determine whether the vehicle is balanced based on the four-wheel data. When the forklift forks are inserted into the support groove at the bottom of the pressure plate, the pressure hydraulic rod can adjust the height of the pressure plate by extending and retracting. The retraction simulates the weight of the goods, and the data from the gravity detection module determines whether the counterweight can keep the forklift balanced at different cargo heights. If the data difference is too large, it indicates a risk of imbalance under the current load. In actual operation, due to different cargo sizes, the center of gravity of the cargo also differs. To better reflect real-world conditions, the adjusting screw can also be rotated to adjust the gravity simulation mechanism. The position of the pressure plate on the forks is adjusted to simulate the load conditions of different sized goods. Some forklifts have forks that provide an elevation angle. Slider 1 can move back and forth on slider 2, and can simultaneously adjust the position of the pressure hydraulic rod as the forks tilt upward, thus ensuring that the pressure direction is changed without changing the position of the pressure plate on the forks. In addition, the gravity simulation mechanism can also move left and right in the adjustment compartment, and work with the support hydraulic rod to extend upward to support the detection plate and tilt it to the side, simulating the centrifugal force when the forklift is turning with a load. At the same time, the limit telescopic rod can be flipped during the test, so that the limit rod is located above the rear end of the forklift for protection and to prevent it from tipping over during the test. This method can effectively simulate the situation of the forklift in actual operation. Compared with the traditional counterweight test method, it is more realistic and the test structure is more accurate. Attached Figure Description

The screw hole 223 is opened on the slide plate 221 and is threadedly engaged with both ends of the bidirectional screw 204. By controlling the rotation of the bidirectional screw 204, the distance between the measuring mechanisms 22 can be adjusted to adapt to forklifts with different wheelbases. The gravity detection module 222 can measure the pressure applied to each wheel separately. This type of device is existing technology and will not be described in detail here.

[0033] A control mechanism 4 is slidably provided in the slide groove 123. The control mechanism 4 includes a limiting plate 401 and an adjusting screw 402. The limiting plate 401 is slidably provided in the slide groove 123. The adjusting screw 402 is rotatably provided on the side of the limiting plate 401 near the support mechanism 11. The adjusting screw 402 is provided inside the adjusting chamber 121. The adjusting screw 402 is electrically controlled.

[0034] The gravity simulation mechanism 3 includes an adjusting slider 31 and a pressure plate 32. The adjusting slider 31 includes a slider one 311 and a slider two 313. Slider one 311 is located above slider two 313. Slider one 311 has symmetrical sliding holes 312 through both ends. Slider two 313 has protrusions 314 at the four corners of its top wall. Slider two 313 also has a sliding rod 315 above it. The sliding rod 315 passes through the sliding holes 312 and is located between the protrusions 314. A spring 316 is provided between the side wall of slider one 311 and the protrusions 314. The spring 316 is sleeved on the outside of the sliding rod 315. Screw hole two 317 is provided through slider two 313. Screw hole two 317 is threadedly engaged with adjusting screw 402. The top wall of slider one 311 is attached to the top wall of adjusting chamber 121. The bottom wall of slider two 313 is attached to the bottom wall of adjusting chamber 121. A pressure hydraulic rod 318 is provided on the top wall of slider one 311. A ball head 319 is provided on the top wall of pressure hydraulic rod 318.

[0035] The pressure plate 32 includes a plate body 321, a groove 322 and a support groove 323. The groove 322 is located at the bottom of the plate body 321, and the ball head 319 is located in the groove 322. The support groove 323 is symmetrically opened on the bottom wall of the plate body 321.

[0036] In practical use, first, control the bidirectional screw 204 to adjust the measuring mechanism 22 to move closer to or further away from each other, adjusting the distance according to the wheelbase of the forklift being tested. Then, insert the forklift forks into the support groove 323 at the bottom of the pressure plate 32, and rotate the adjusting screw 402 to adjust the position of the gravity simulation mechanism 3, so that the pressure plate 32 is in the middle of the forks. Subsequently, during the test, flip the limiting telescopic rod 205, adjusting the extension and retraction of the limiting telescopic rod 205 according to the size of the forklift, so that the limiting rod 206 is located above the rear end of the vehicle body and slightly higher than the rear end of the vehicle body, preventing the vehicle from tipping over during the test. The lever 318 extends and retracts along with the up-and-down movement of the forks, pausing the movement of the forks and the extension and retraction of the hydraulic lever 318 at different heights. During the pause, the hydraulic lever 318 retracts to simulate the weight of the load, performing basic measurements. Data from the gravity detection module 222 is used to determine whether the counterweight can keep the forklift balanced at different load heights. If the difference in data from the four wheels is too large, it indicates a risk of imbalance under the current load. In actual operation, due to the different sizes of the loads, the center of gravity of the loads also varies. To reflect real-world conditions, the adjustment screw 402 is rotated to adjust the gravity simulation mechanism 3. The position of the pressure plate 32 is adjusted to change its position on the forks, moving it towards the end of the forks to simulate different load sizes (the farther the center of gravity is from the vehicle body, the weaker the load capacity; therefore, only the far end needs to be tested, and there is no need to move the pressure plate 32 closer to the vehicle body for testing). For more stable loading, some forklifts have forks that provide an elevation angle. Slider 1 311 can move back and forth on slider 2 313. When the forks tilt upwards, slider 1 311 will be pulled towards the vehicle body, thus simulating the load situation without changing the position of the pressure plate 32 on the forks. The pressure direction can be changed when the fork is in position, and the gravity simulation mechanism 3 can also move left and right in the adjustment chamber 121. With the support hydraulic rod 113, it extends upward to support the detection plate 2 and tilt it to the side to simulate the centrifugal force when the forklift is turning with a load. After the test, the limit rod 206 is removed, the vehicle drives away, and the adjustment screw 402 is rotated to move the gravity simulation mechanism 3 towards the support mechanism 11. During the movement, the slider 2 313 contacts the side wall of the reset block 124 and is centered and reset under the contraction of the reset block 124, so that the next forklift can be tested.
