Abstract
Description
Technical Field
[0001] This utility model relates to the field of forklift mast inspection technology, and in particular to a forklift mast inspection device. Background Technology
[0002] The forklift mast is the core structure of the forklift lifting system. It consists of inner and outer masts, lifting chains, hydraulic cylinders, rollers, and other components. It achieves vertical lifting of the forks and forward and backward tilting of the mast through hydraulic drive, which directly affects the stability of cargo handling and operational flexibility. Because the mast is subjected to heavy impacts and frequent extension and retraction over a long period of time, it is prone to structural damage. If it is not inspected in time, it may lead to equipment failure.
[0003] Traditional forklift mast inspection involves visual inspection, manual testing, and the use of simple tools to check for deformation, cracks, or rust in the mast structure, measure the verticality of the columns and the degree of local deformation, and conduct pressure tests on the forklift mast by applying pressure through a pressure system to test its load-bearing capacity. After the test, the pressure needs to be restored to normal to ensure that the mast moves smoothly without jamming.
[0004] Traditional forklift mast inspection often relies on simple support frames to fix the mast. This is prone to instability, which can cause the mast to shake or shift during inspection, affecting the accuracy of deformation measurement. Furthermore, it is difficult to adapt to different mast models. During pressure testing, it is also difficult to apply pressure to specific sections of the mast, leading to missed defects. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forklift mast inspection device, including a base, a baffle fixedly connected to one end of the base, a mast slidably connected to the upper surface of the base, and a clamping assembly provided on the top of the base;
[0007] The clamping assembly includes a clamp, the outer wall of which is slidably connected to the top of the base. A guide post is fixedly connected to the outer wall of the clamp, and a fixing block is slidably connected to the outer wall of the guide post. A fixing plate two is fixedly connected to the bottom of the fixing block, and a cylinder is fixedly connected to the outer wall of the fixing plate two. A connecting post one is fixedly connected to the output end of the cylinder, and a pushing block is fixedly connected to one end of the connecting post one. A rotating shaft two is fixedly connected to the outer wall of the pushing block, and a connecting rod is rotatably connected to the outer wall of the rotating shaft two. A rotating shaft one is rotatably connected to one end of the connecting rod, and a connecting block is fixedly connected to one end of the rotating shaft one. A guide rail two is slidably connected to the outer wall of the connecting block, and a fixing plate one is fixedly connected to the outer wall of the guide rail two.
[0008] Furthermore, a guide rail is fixedly connected to the top of the clamp, a slider is slidably connected to the outer wall of the guide rail, a telescopic rod is fixedly connected to the outer wall of the slider, a button is provided on one side of the outer wall of the telescopic rod, a connecting post is fixedly connected to the outer wall of the button, a locking block is fixedly connected to one end of the connecting post, a spring is provided inside the telescopic rod, a telescopic rod is slidably connected inside the telescopic rod, a pressure detector is provided on the outer wall of the telescopic rod, a locking groove is provided inside the telescopic rod, and the locking block is slidably connected to the outer wall of the locking groove.
[0009] Furthermore, the clamps are respectively installed on both sides of the outer wall of the gantry, and one end of the linkage block is fixedly connected to the outer wall of the clamp.
[0010] Furthermore, one end of the spring is fixedly connected to the inner wall of the telescopic rod, and the other end of the spring is fixedly connected to the outer wall of the locking block.
[0011] Furthermore, the outer walls of both the second fixing plate and the first fixing plate are fixedly connected to the bottom of the base, and the cylinder is located below the base.
[0012] Furthermore, the outer wall of the second connecting column is slidably connected to the inside of the first telescopic rod, and the pressure detector is installed above the gantry.

[0014] Furthermore, the linkage block is disposed between the two fixed plates, and the fixed block is disposed on one side of the outer wall of the clamp.
[0015] This utility model has the following beneficial effects:
[0016] In this invention, a cylinder drives the output end connecting column one to push the push block to move linearly. The push block is hinged to the connecting rod through the rotating shaft two, causing the connecting rod to swing around the rotating shaft one in an arc, thereby driving the connecting block to slide directionally along the guide rail two on the fixed plate one. The connecting blocks on both sides are rigidly connected to synchronously pull the symmetrically arranged clamps, forming a bidirectional clamping of the mast. This solves the problem that traditional forklift mast testing is prone to mast shaking or displacement due to unstable fixing, and is difficult to adapt to different mast models, thus achieving the effect of fixed clamping of the mast.
[0017] In this invention, the locking is released by pressing the button. The button drives the connecting column two to move axially, overcoming the preload of the spring and causing the locking block to disengage from the slot of the telescopic rod two, thus releasing the locking state of the telescopic rod two. At this time, the extension length of the telescopic rod two can be manually adjusted, and the guide rail one and the slider ensure that the pressure detector moves smoothly along a straight line. This solves the problem of difficulty in applying precise pressure to different areas of the gantry during pressure testing, which leads to missed defects. It realizes pressure testing of different areas of the gantry. Attached Figure Description

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.
[0027] Reference Figure 1 - Figure 6The present invention provides an embodiment of a forklift mast inspection device, including a base 1. The base 1 serves as the basic platform of the entire inspection device, providing a reference for the installation and support of other components. A baffle 2 is fixedly connected to one end of the base 1. The baffle 2 is located at one end of the base 1 and contacts the mast 3, serving to block and position the mast 3, ensuring that the mast 3 is fixed in position on the inspection device. The mast 3 is slidably connected to the upper surface of the base 1, and a clamping assembly is provided on the top of the base 1.
[0028] The clamping assembly includes a clamp 4, the outer wall of which is slidably connected to the top of the base 1. The clamp 4 is disposed on both sides of the outer wall of the gantry 3 for bidirectional clamping of the gantry 3. A guide post 6 is fixedly connected to the outer wall of the clamp 4, and a fixing block 5 is slidably connected to the outer wall of the guide post 6. The fixing block 5 provides sliding support for the guide post 6, ensuring that the clamp 4 moves along a straight trajectory during movement. A fixing plate 26 is fixedly connected to the bottom of the fixing block 5, and a cylinder 12 is fixedly connected to the outer wall of the fixing plate 26. The output end of the cylinder 12 is fixed. A connecting column 13 is connected, and a push block 14 is fixedly connected to one end of the connecting column 13. A rotating shaft 18 is fixedly connected to the outer wall of the push block 14. A connecting rod 16 is rotatably connected to the outer wall of the rotating shaft 18. A rotating shaft 17 is rotatably connected to one end of the connecting rod 16. A connecting block 7 is fixedly connected to one end of the rotating shaft 17. Driven by the connecting rod 16, the connecting block 7 slides along the guide rail 19 in a directional direction, converting the swing motion of the connecting rod 16 into the linear motion of the clamp 4, thus clamping and fixing the gantry 3. A sliding guide rail 19 is connected to the clamp 4. A fixing plate 15 is fixedly connected to the outer wall of the guide rail 19. A guide rail 9 is fixedly connected to the top of the clamp 4 and slides with the slider 8. The guide rail 9 provides a sliding track for the slider 8, thereby driving the pressure detector 11 to move and realize pressure detection in different areas of the gantry 3. The slider 8 is slidably connected to the outer wall of the guide rail 19. A telescopic rod 10 is fixedly connected to the outer wall of the slider 8. A button 21 is provided on one side of the outer wall of the telescopic rod 10. Button 21... A connecting column 23 is fixedly connected to the outer wall, and a locking block 25 is fixedly connected to one end of the connecting column 23. A spring 24 is installed inside the telescopic rod 10. The telescopic rod 10 can change the position of the pressure detector 11 by telescopic adjustment, so that it can adapt to the detection requirements of different heights of the gantry 3. A telescopic rod 20 is slidably connected inside the telescopic rod 10. The pressure detector 11 is installed on the outer wall of the telescopic rod 20. A locking groove 22 is installed inside the telescopic rod 20. The locking block 25 is slidably connected to the outer wall of the locking groove 22.
[0029] Reference Figure 1 - Figure 6The clamps 4 are respectively set on both sides of the outer wall of the gantry 3. One end of the linkage block 7 is fixedly connected to the outer wall of the clamp 4, and one end of the spring 24 is fixedly connected to the inner wall of the telescopic rod 10. The spring 24 provides preload force so that the locking block 25 can be locked into the slot 22 of the telescopic rod 20, thereby locking the telescopic rod 20. The other end of the spring 24 is fixedly connected to the outer wall of the locking block 25. The outer walls of the fixing plate 26 and the fixing plate 15 are both fixedly connected to the bottom of the base 1. The fixing plate 15 provides installation support for the guide rail 29, ensuring that the position of the guide rail 29 is fixed, thereby ensuring that the linkage block 7 slides along the accurate track. Fixed plate 26 provides a mounting base for cylinder 12 and fixed block 5, ensuring that cylinder 12 can stably drive the clamp 4 to move. Cylinder 12 is located below base 1. Connecting column 23 is slidably connected to the outer wall of telescopic rod 10. Pressure detector 11 is located above gantry 3. One end of clamp 4 is slidably connected to the outer wall of baffle 2. Baffle 2 is located at one end of gantry 3. Linking block 7 is located between fixed plates 26. Fixed block 5 is located on one side of the outer wall of clamp 4. The pressure detector 11 used in this application is model Drucker DPI610E, which is prior art and will not be described in detail here.
[0030] Working principle: The base 1 serves as a basic platform. One end of the base 1 is initially positioned on the gantry 3 via a baffle 2, limiting its longitudinal displacement. The starting cylinder 12 drives the output connecting column 13 to push the pushing block 14 in a linear motion. The pushing block is hinged to the connecting rod 16 via a rotating shaft 18, causing the connecting rod to swing in an arc around the rotating shaft 17. This, in turn, drives the connecting block 7 to slide directionally along the guide rail 19 on the fixed plate 15. The two connecting blocks 7 on both sides are rigidly connected and synchronously pull the symmetrically arranged clamps 4, causing the two clamps to slide towards each other along the top guide rail of the base 1, forming a bidirectional clamping of the gantry 3. The column 6 and the fixing block 5 ensure the linear accuracy of the movement trajectory of the clamp 4, while the fixing plate 26 provides a mounting base for the cylinder 12. In addition, during the pressure detection stage, the operator can unlock the device by pressing the button 21. The button 21 drives the connecting column 23 to move axially, overcoming the preload of the spring 24, and causing the locking block 25 to disengage from the slot 22 of the telescopic rod 20, thus releasing the locking state of the telescopic rod 20. At this time, the extension length of the telescopic rod 20 can be manually adjusted, and the guide rail 9 and the slider 8 ensure that the pressure detector 11 moves smoothly along a straight line, realizing pressure detection of different areas of the gantry.
