DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and indicated in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0018] The lifting stability detection device for the lifting frame of a forklift disclosed by the utility model is mainly applied to the traditional forklift in the object lifting process. Due to long-time operation, the first chain wheel, the fork frame and the chain will be worn out, resulting in an increase in the matching gap, thereby affecting the stability of the lifting frame. There may be a forward inclination of goods to both sides or one side and a displacement, thereby affecting the stability and operation efficiency of the forklift. There may even be potential safety hazards and economic losses. Therefore, a detection device is urgently needed to quickly detect the stability of the forklift lifting frame in the lifting process.

[0019] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a lifting stability detection device for the lifting frame of a forklift, comprising a forklift lifting frame, a pressing plate 10 and a fixed seat 6, the forklift lifting frame comprising a chassis 1, further comprising:

[0020] The measuring mechanism is located on the top outer wall of the fixed seat 6 and comprises two mounting frames 7 and a limiting frame 19. The outer wall of one side of the mounting frame 7 and the outer wall of one side of the limiting frame 19 are both provided with mounting grooves. The inner wall of the mounting groove is slidably connected with a mounting frame 15. The inner wall of one side of the mounting frame 15 is provided with three fixed sleeves 17. The inner wall of the fixed sleeve 17 is slidably connected with a mounting rod 18. One end of the mounting rod 18 is fixedly connected with a connecting plate 16.

[0021] The driving mechanism is located on the top outer wall of the chassis 1.

[0022] Among them, the circumferential outer wall of the mounting rod 18 is provided with a scale, so that the displacement distance of the pressing plate 10 in the lifting process of the forklift lifting frame can be intuitively observed.

[0023] In the specific implementation process, the fixing seat 6 is a "N" shaped structure, and a connecting frame 14 is arranged between the two adjacent mounting frames 15. The fixing seat 6 adopts the "N" shaped structure, mainly to provide sufficient support area and stability, and facilitate the installation and positioning of the measuring mechanism. The connecting frame 14 firmly connects the two mounting frames 15 together to form a stable measuring platform. At the same time, the connecting frame 14 can also provide additional support points, and additional measuring equipment or sensors can be installed according to actual detection needs to obtain more comprehensive measurement data.

[0024] Specifically, in use, different sample weight pressing plates 10 are placed in the forklift lifting frame in turn. During the lifting process of the forklift lifting frame by the driving mechanism, since the two adjacent mounting frames 15 are connected by the connecting frame 14, and one side of the two mounting frames 15 is connected with the driving mechanism, when the driving mechanism drives the pressing plate 10 to lift upward, the three mounting frames 15 and the fixing sleeve 17, the mounting rod 18 and the connecting plate 16 in each mounting frame 15 will also slide in the mounting groove at the same time. Before the pressing plate 10 is lifted, the connecting plate 16 close to both sides and one side of the pressing plate 10 is pulled to contact and fit with the corresponding surface, and the scale exposed on the mounting rod 18 at this moment is recorded as D. When the pressing plate 10 is lifted with the forklift lifting frame, the pressing plate 10 without binding will be displaced to a certain extent in one direction or multiple directions due to external force and loosening of parts of the forklift lifting frame. At this moment, one side or one edge of the pressing plate 10 will extrude and push the corresponding connecting plate 16. Since the mounting rod 18 is in sliding connection with the fixing sleeve 17, the connecting plate 16 pushes the mounting rod 18 to slide into the fixing sleeve 17. Then, when the forklift lifting frame is lifted to a certain height, the operator records the scale exposed on the mounting rod 18 again, which is recorded as d. Then, the displacement distance of the pressing plate 10 is (D-d). If the distance (D-d) is greater than the normal limited displacement distance, it is considered that there is a problem with the stability of the forklift lifting frame, which needs to be further checked or adjusted. The device can simply, intuitively and multi-directionally detect the stability of the forklift lifting frame, so as to avoid potential safety hazards and economic losses.

[0025] Referring to Figure 1 and Figure 3 In a preferred embodiment, the driving mechanism includes two stands 2 and a motor 11. One side of the stand 2 is provided with a mounting plate 3. The opposite inner wall of the mounting plate 3 is provided with a connecting rod 4. The circumferential outer wall of the connecting rod 4 is connected with a first sprocket 5 through a bearing near the central position. One side of the stand 2 is connected with a moving rod through sliding connection. The outer wall of the moving rod is sleeved with two forks 9. The first sprocket 5 is wound with a chain. The output shaft of the motor 11 is fixedly connected with a second sprocket. The two ends of the chain are fixedly connected with the moving rod and the second sprocket.

[0026] Two outer walls of one side of the mounting frame 15 are provided with connecting buckles 12, which are sleeved on the outer wall of the moving rod. This arrangement facilitates the firm fixation of the mounting frame 15 on the moving rod, so that the mounting frame 15 moves up and down with the moving rod.

[0027] In the specific implementation process, four universal wheels are installed on the bottom outer wall of the base frame 1. The base frame 1 has an "H" shape structure, and the "H" shape structure of the base frame 1 has excellent rigidity and load-bearing capacity. Through the transverse and longitudinal support structures, the base frame 1 can effectively disperse and bear the weight from the forklift lifting frame and the test load, ensuring the stability and safety of the entire detection device.

[0028] Specifically, when the motor 11 starts, the output shaft drives the second sprocket to rotate. Since the two ends of the chain are fixedly connected with the moving rod and the second sprocket respectively, the movement of the chain will drive the moving rod to slide on the stand 2. With the sliding of the moving rod, the fork frame 9 will also move, so as to cooperate with the measuring mechanism to detect whether displacement occurs during the lifting of the pressing plate 10.

[0029] Referring to Figure 1 and Figure 3 In a preferred embodiment, two limiting grooves 13 are formed in one side outer wall of the fixed seat 6, and two protrusions 8 are installed on one side outer wall of the base frame 1, which cooperate with the limiting grooves 13.

[0030] Specifically, the cooperation of the limiting grooves 13 and the protrusions 8 enables the base frame 1 to be accurately positioned on the fixed seat 6, thereby ensuring the stability and accuracy of the entire detection device during testing. This helps to reduce measurement errors caused by inaccurate positioning, and the movement range of the base frame 1 is effectively limited, which can prevent accidental sliding or displacement of the base frame 1 during testing, thereby protecting the safety of the detection device and the test equipment.

[0031] Working principle: when in use, first place the pressing plate 10 of different sample weights in the forklift lifting frame in turn, during the lifting of the forklift lifting frame by the driving mechanism, since the two adjacent installation frames 15 are connected by the connecting frame 14, and one side of the two installation frames 15 is connected with the driving mechanism by the connecting buckle 12, therefore when the driving mechanism lifts the pressing plate 10 upward, the three installation frames 15 and the fixed sleeve 17, the installation rod 18 and the connecting plate 16 in each installation frame 15 will also slide in the installation slot synchronously, before the pressing plate 10 is lifted, pull the connecting plate 16 close to the two sides and one side of the pressing plate 10 to contact and fit with the corresponding surface, and record the scale exposed on the installation rod 18 at that time, marked as D, when the pressing plate 10 is lifted with the forklift lifting frame, the pressing plate 10 without binding will be displaced to a certain extent in one direction or multiple directions due to external force and loosening of parts of the forklift lifting frame, at this time, one side or one edge of the pressing plate 10 will extrude and push the corresponding connecting plate 16, since the installation rod 18 is connected with the fixed sleeve 17 in sliding mode, therefore the connecting plate 16 pushes the installation rod 18 to slide into the fixed sleeve 17, then when the forklift lifting frame is lifted to a certain height, the operator records the scale exposed on the installation rod 18 again, marked as d, then the displacement distance of the pressing plate 10 is (D-d), if the distance (D-d) is greater than the normal limited displacement distance, then it is considered that the stability of the forklift lifting frame has problems, which needs to be further checked or adjusted.

[0032] The above merely describes a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. The substitution can be the substitution of part of the structure, device, method step, or the complete technical solution. According to the technical solution and the inventive concept of the present application, equivalent substitution or change should be covered in the protection scope of the present application.
