Description

Technical Field

[0001] This utility model relates to the field of forklift mast testing technology, specifically a forklift mast column parallelism testing device. Background Technology

[0002] The mast column is an important component of the forklift mast system. It mainly bears the weight of the goods and various forces generated by the forklift during operation. It provides stable support for the entire mast structure, ensuring that the forklift can safely lift and move goods.

[0003] When performing a comprehensive inspection of the parallelism of forklift mast columns, most workers use vernier calipers to check the columns. This process is quite complex and it is difficult to collect error data, resulting in low inspection accuracy. To address this, we propose a forklift mast column parallelism detection device. Utility Model Content

[0004] The purpose of this invention is to provide a forklift mast column parallelism detection device to solve the problems mentioned in the background art, such as the complex detection process and the difficulty in collecting error data. To achieve the above objectives, this utility model provides the following technical solution: a forklift mast column parallelism detection device, comprising a connecting rod and a detection component. The detection component is disposed at the bottom of the connecting rod and includes a support rod fixedly connected to the bottom of the connecting rod. A sliding groove is formed at the bottom of the support rod, and two sliders are slidably connected inside the sliding groove. A distance measuring instrument is fixedly connected to each slider. A telescopic rod is fixedly connected to the bottom of the support rod, and a connecting plate is fixedly connected to the bottom of the telescopic rod. Two distance measuring instruments are fixedly connected to the bottom of the connecting plate, and the two distance measuring instruments are symmetrically distributed. When detecting the forklift mast columns, the first distance measuring instrument can detect the distance between the surfaces of the columns on both sides of the forklift mast, and the second distance measuring instrument can detect the distance between the middle parts of the columns on both sides of the forklift mast. The detection data is then transmitted to the back-end system in real time for recording. When the data from both sides are different, the error data of the parallelism between the forklift mast columns can be quickly understood, facilitating the operation of the detection work and improving the efficiency of the detection work.

[0005] Further preferably, a movable component is provided at the bottom of the connecting rod. The movable component includes a support base, which is located below the connecting rod. Two support frames are fixedly connected to the top of the support base, and the two support frames are symmetrically distributed. One of the support frames has a rotating groove on both sides. A servo motor is fixedly connected to the top of the support base. A lead screw is fixedly connected to the transmission end of the other side of the servo motor. The outer side of the lead screw is rotatably connected to the inside of the rotating groove through a bearing, which can drive the detection component to reciprocate, reduce the labor of the staff, and ensure the stability of the detection data.

[0006] More preferably, another support frame is internally fixedly connected to a fixing rod, and a connecting frame is slidably connected to the outside of the fixing rod, with the top of the connecting frame fixedly connected to the bottom of the connecting rod. The lead screw is threadedly connected to a connecting frame, with the top of the connecting frame fixedly connected to the bottom of the connecting rod. An adjustment component is provided on the top of the support base.

[0007] Further preferably, the adjusting component includes two grooves, which are symmetrically distributed on the top of the support base. Several rotating rods are fixedly connected inside the grooves and arranged in a linear array. Rollers are rotatably connected to the outer sides of the rotating rods. A connecting groove is provided on the top of the support base, and a limiting block is slidably connected inside the connecting groove. A support plate is fixedly connected to the top of the limiting block, and the bottom of the support plate is rotatably connected to the side surface of the roller. A clamping component is provided inside the support base to reduce the friction between the forklift mast column and the support base, assisting the clamping component in moving the forklift mast column, ensuring that the forklift mast column is installed in the middle of the detection device for detection, and improving the accuracy of the detection work.

[0008] More preferably, the clamping assembly includes two rotating grooves, which are respectively opened on the front and back of the support base. A servo motor is fixedly connected to the front of the support base, and a bidirectional lead screw is fixedly connected to the transmission end of the back of the servo motor. The outer side of the bidirectional lead screw is rotatably connected to the inside of the rotating groove through a bearing. The outer side of the bidirectional lead screw has two threaded rings that are symmetrically distributed.

[0009] More preferably, the side surface of the threaded ring is fixedly connected to two limiting rods, which are symmetrically distributed. The top of the support base is provided with four sliding grooves, which are distributed at the four corners. The inside of the support base is fixed with two fixing rods, which are symmetrically distributed. The side surface of the fixing rods is slidably connected to two connecting frames, which are symmetrically distributed. The outer side of the connecting frame is fixedly connected to the other end of the limiting rod. The outer side of the connecting frame is slidably connected to the inside of the sliding groove. The top of the connecting frame is fixedly connected to a push rod. One side of the push rod is fixedly connected to a clamping plate, which can adjust the position of the forklift mast column and effectively prevent the forklift mast column from tilting, thus preventing inaccurate detection data.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In this invention, when inspecting the mast columns of a forklift, a distance measuring instrument 1 can measure the distance between the surfaces of the columns on both sides of the forklift mast, and a distance measuring instrument 2 can measure the distance between the middle parts of the columns on both sides of the forklift mast. The detection data is then transmitted to the back-end system in real time for recording. When the data from the two sides are different, the error data of the parallelism between the mast columns can be quickly understood, which facilitates the operation of the inspection work and improves the efficiency of the inspection work.

[0012] In this invention, before inspecting the forklift mast column, the rollers are connected to the support plate by rotation. Combined with the weight of the forklift mast column itself, the rollers allow the support plate to move back and forth, reducing friction between the forklift mast column and the support base. This assists the clamping assembly in moving the forklift mast column, ensuring it is installed in the center of the inspection device for testing, thus improving the accuracy of the inspection.

[0024] The usage and advantages of this utility model: The forklift mast column parallelism detection device operates as follows:

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when using this device, the operator first places the forklift mast column on top of the support plate 406. Then, the operator starts the servo motor 502, which drives the bidirectional lead screw 503 to rotate. Through the sliding connection between the connecting frame 508 and the fixed rod 507, and the cooperation between the connecting frame 508, the limiting rod 505, and the threaded ring 504, the connecting frame 508 can limit the threaded ring 504 via the limiting rod 505.

The limiting rod 505 drives the connecting frame 508 to move towards the center, allowing the connecting frame 508 to drive the clamping plate 7 towards the center of the support base 301 via the push rod 6. This allows the clamping plate 7 to clamp the forklift mast column on top of the support plate 406.

Furthermore, the sliding motion of the connecting groove 404 and the limiting block 405 allows the support plate 406 to be limited. Then, the worker... The operator can slide the slider 203 through the groove 202 to adjust the position of the two distance measuring instruments 204, so that the distance measuring instruments 204 are parallel to the forklift mast column. Then, the height of the distance measuring instrument 207 can be adjusted through the telescopic rod 205, so that the distance measuring instrument 207 is parallel to the inside of the forklift mast column. Next, the servo motor 304 can be started to drive the lead screw 305 to rotate. The fixed rod 306 is slidably connected to the connecting frame 307.

This allows the distance measuring instrument 204 to detect the distance on the surface of the forklift mast column, and the distance measuring instrument 207 to detect the distance at the center of the forklift mast column. The detection data is then transmitted to the back-end system in real time for recording, completing the parallelism detection of the forklift mast column.
