Description

Technical Field

[0001] This utility model relates to the field of logistics handling equipment technology, and in particular to a tilting structure for a reach truck mast. Background Technology

[0002] As one of the core components of a forklift, the height and tilt angle adjustment functions of the forklift mast are crucial. Some traditional forklift mast height adjustment relies on manual operation, which is cumbersome and inefficient. When facing a large number of cargo handling tasks, frequent manual height adjustment seriously affects work efficiency. Moreover, manual adjustment is difficult to guarantee the accuracy of the height. In some scenarios with strict requirements on the placement height of goods, errors are prone to occur, affecting the quality of cargo storage and handling. Some forklift masts have a fixed tilt angle, which cannot be adjusted according to actual needs when handling goods, causing the goods to easily slip. Therefore, we have introduced a reach truck mast tilting structure. Utility Model Content

[0003] The main objective of this invention is to provide a tilting structure for a reach truck mast, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A tilting structure for a reach truck mast includes a fixed frame. Side plates are fixedly connected to the lower left and lower right ends of the fixed frame. Mounting holes are provided at the upper and lower front ends of the two side plates. Sliding grooves are provided at the rear of the left and right side plates of the fixed frame. A height adjustment device is fixedly connected to the middle of the upper end of the fixed frame. A tilt adjustment device is fixedly connected to the front left end of the height adjustment device.

[0006] The height adjustment device includes a first drive motor, the output end of which passes through the fixed frame and is fixedly connected to a screw. A displacement plate is movably connected to the outer surface of the screw. A groove is opened at the front end of the displacement plate. Slider blocks are fixedly connected to the rear left and rear right ends of the displacement plate. The first drive motor is fixedly connected to the middle of the upper end of the fixed frame.

[0007] Preferably, the tilt adjustment device includes a second drive motor, the output end of which passes through the displacement plate and is fixedly connected to a main rotating rod. The left and right sides of the outer surface of the main rotating rod are both fixedly connected to main gear blocks. The upper parts of the outer surfaces of the two main gear blocks are meshed together by a meshing assembly. The second drive motor is fixedly connected to the lower left end of the displacement plate.

[0008] By adopting the above technical solution: the No. 2 drive motor serves as the power source to provide power for tilt adjustment. By being fixedly connected to the main rotating rod, the rotational power of the motor can be transmitted to the main rotating rod, thereby driving the main gear block to rotate. The main gear block cooperates with the meshing components to further transmit and convert power, so as to achieve the adjustment of the tilt angle of the forklift frame. This structural design makes the power transmission path clear and efficient, providing stable power for tilt adjustment.

[0009] Preferably, the meshing assembly includes a secondary rotating rod, with a secondary gear block fixedly connected to the left and right sides of the outer surface of the secondary rotating rod, and a forklift frame fixedly connected to the middle of the outer surface of the secondary rotating rod. The left and right ends of the secondary rotating rod are respectively movably connected between the upper left and right walls of the displacement plate via bearings.

[0010] By adopting the above technical solution, the secondary rotating rod and its secondary gear block mesh with the main gear block, converting the power of the main rotating rod into its own rotation, thereby driving the forklift frame fixed in the middle to rotate, thus realizing tilt adjustment.

[0011] Preferably, the lower end of the screw is movably connected to the middle of the lower plate wall of the fixed frame via a bearing, and the two sliders are slidably connected in the grooves respectively.

[0012] By adopting the above technical solution—the sliding connection between the slider and the groove—the rotation of the displacement plate is restricted, allowing the displacement plate to move only vertically along the screw, thereby achieving precise height adjustment and enhancing the stability and reliability of the entire height adjustment structure.

[0013] Preferably, the right end of the main rotating rod is movably connected to the lower part of the right wall of the displacement plate via a bearing.

[0014] By adopting the above technical solution, the stability of the main rotating rod during rotation is ensured, enabling the main rotating rod to rotate smoothly under the drive of the No. 2 drive motor. This avoids the main rotating rod shaking from affecting the meshing effect of the main gear block and the secondary gear block, thereby ensuring that the tilt adjustment device can work accurately and reliably, and improving the accuracy and stability of the forklift frame tilt adjustment.

[0015] Preferably, the two secondary gear blocks are meshed one-to-one on the upper outer surface of the two primary gear blocks, and the forklift frame does not contact the displacement plate.

[0016] By adopting the above technical solution, the forklift frame does not come into contact with the displacement plate, thus avoiding interference with the displacement plate during the tilting process of the forklift frame and ensuring the smooth tilting action of the forklift frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this utility model, by setting up a height adjustment device, using a No. 1 drive motor to drive the screw, and cooperating with the sliding connection between the displacement plate and the slider and the slide groove, automated and precise height adjustment is achieved. This design greatly improves work efficiency. When facing a large number of cargo handling tasks, the gantry height can be adjusted quickly and accurately without frequent manual operation, saving labor costs.

[0019] 2. In this utility model, a tilt adjustment device composed of a second drive motor, a main rotating rod, a main gear block, a secondary rotating rod, and a secondary gear block achieves flexible and precise tilt angle adjustment. When handling goods, the tilt angle of the forklift frame can be adjusted at any time according to actual needs, effectively preventing goods from slipping and improving the safety of goods handling. Furthermore, the use of gear meshing transmission ensures the smoothness and reliability of transmission, reduces vibration and noise during adjustment, not only improving the safety of forklift operation but also extending the service life of the equipment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A tilting structure for a reach truck mast includes a fixed frame 1. Side plates 2 are fixedly connected to the lower left and lower right ends of the fixed frame 1. Mounting holes 6 are opened at the upper front and lower front ends of the two side plates 2. Sliding grooves 3 are opened at the rear left and rear right sides of the fixed frame 1. A height adjustment device 4 is fixedly connected to the middle upper end of the fixed frame 1. A tilt adjustment device 5 is fixedly connected to the front left end of the height adjustment device 4.

[0030] In this embodiment, the height adjustment device 4 includes a first drive motor 41. The output end of the first drive motor 41 passes through the fixed frame 1 and is fixedly connected to a screw 42. A displacement plate 44 is movably connected to the outer surface of the screw 42. A groove 45 is opened at the front end of the displacement plate 44. Slider 43 is fixedly connected to the rear left and rear right ends of the displacement plate 44. The first drive motor 41 is fixedly connected to the middle of the upper end of the fixed frame 1. The lower end of the screw 42 is movably connected to the middle of the lower plate wall of the fixed frame 1 through a bearing. The two sliders 43 are slidably connected in the groove 3 respectively.

[0031] Through the above scheme: when it is necessary to adjust the tilt angle of the forklift frame 543, the second drive motor 51, fixed to the lower left end of the displacement plate 44, is started. Its output end drives the main rotating rod 52, which is fixedly connected to it, to rotate. The right end of the main rotating rod 52 is movably connected to the lower right wall of the displacement plate 44 through a bearing to ensure smooth rotation. The rotation of the main rotating rod 52 drives the main gear blocks 53 on the left and right sides of its outer surface to rotate synchronously. The main gear blocks 53 mesh with the secondary gear blocks 542 in the meshing assembly 54. Since the secondary gear blocks 542 are respectively fixed to the left and right sides of the outer surface of the secondary rotating rod 541, and the left and right ends of the secondary rotating rod 541 are movably connected to the left wall of the displacement plate 44 through bearings, Between the upper part and the upper part of the right plate wall, the rotation of the main gear block 53 drives the secondary gear block 542 to drive the secondary rotating rod 541 to rotate, which in turn causes the forklift frame 543, which is fixed in the middle of the outer surface of the secondary rotating rod 541, to rotate, thereby realizing the tilt angle adjustment. Furthermore, the forklift frame 543 does not contact the displacement plate 44 to avoid interference. The tilt adjustment device 5 and the meshing component 54 adopt a design of motor drive combined with gear meshing transmission, which has a compact and reasonable structure. The motor drive provides stable power and can accurately and quickly adjust the tilt angle of the forklift frame 543 to meet the needs of different handling scenarios. At the same time, the forklift frame 543 does not contact the displacement plate 44, reducing wear and further ensuring the long-term stable operation of the equipment.

[0032] In this embodiment, the tilt adjustment device 5 includes a second drive motor 51. The output end of the second drive motor 51 passes through the displacement plate 44 and is fixedly connected to a main rotating rod 52. Main gear blocks 53 are fixedly connected to the left and right sides of the outer surface of the main rotating rod 52. A meshing assembly 54 is meshed on the upper part of the outer surfaces of the two main gear blocks 53. The second drive motor 51 is fixedly connected to the lower left end of the displacement plate 44. The meshing assembly 54 includes a secondary rotating rod 541. The outer surface of the secondary rotating rod 541... The main rotating rod 52 is fixedly connected to the upper part of the outer surface of the main rotating rod 541 and the lower part of the outer surface of the main rotating rod 541. The left and right ends of the main rotating rod 541 are respectively movably connected between the upper part of the left plate wall and the upper part of the right plate wall of the displacement plate 44 through bearings. The right end of the main rotating rod 52 is movably connected to the lower part of the right plate wall of the displacement plate 44 through bearings. The two secondary gear blocks 542 are meshed and connected to the upper part of the outer surface of the two main gear blocks 53. The forklift frame 543 does not contact the displacement plate 44.

[0033] Through the above scheme: when the forklift frame 543 needs to be tilted, the second drive motor 51, fixed to the lower left end of the displacement plate 44, starts to work. Its output end drives the main rotating rod 52, which is fixedly connected to it, to rotate. The right end of the main rotating rod 52 is movably connected to the lower right wall of the displacement plate 44 through a bearing, ensuring the stability of the rotation. As the main rotating rod 52 rotates, the main gear blocks 53 on the left and right sides of its outer surface also rotate together. The main gear blocks 53 mesh with the secondary gear blocks 542 in the meshing assembly 54. Since the secondary gear blocks 542 are respectively fixed to the left and right sides of the outer surface of the secondary rotating rod 541, and the left and right ends of the secondary rotating rod 541 are movably connected to the left wall of the displacement plate 44 through bearings, Between the upper part and the upper part of the right plate wall, the rotation of the main gear block 53 drives the secondary gear block 542, which in turn drives the secondary rotating rod 541 to rotate. The forklift frame 543, which is fixed in the middle of the outer surface of the secondary rotating rod 541, will tilt as the secondary rotating rod 541 rotates, thus completing the adjustment of the tilt angle. The forklift frame 543 does not contact the displacement plate 44, avoiding interference. The design of the tilt adjustment device 5 and the meshing component 54 uses motor drive and gear meshing transmission to achieve precise adjustment of the tilt angle of the forklift frame 543. Through the meshing between the gears, the smoothness and reliability of the transmission are ensured, effectively reducing vibration and noise during the adjustment process, and improving the safety and accuracy of forklift operation.

[0034] It should be noted that this utility model is a tilting structure for a reach truck mast. When this tilting structure is working, the first drive motor 41 starts, and its output drives the screw 42 to rotate. Since the screw 42 is movably connected to the displacement plate 44, and the sliders 43 at both ends of the displacement plate 44 slide in the grooves 3 at the rear of the left and right walls of the fixed frame 1, the rotation of the displacement plate 44 is restricted, causing the displacement plate 44 to move vertically up and down along the screw 42, thereby achieving height adjustment. When it is necessary to adjust the forklift frame 54... When the tilt angle is 3, the second drive motor 51 starts, and its output end drives the main rotating rod 52 to rotate. The main gear block 53 on the outer surface of the main rotating rod 52 rotates accordingly. The secondary gear block 542, which meshes with the main gear block 53, drives the secondary rotating rod 541 to rotate, thereby causing the forklift frame 543 fixed in the middle of the secondary rotating rod 541 to tilt, thus completing the adjustment of the tilt angle. Throughout the process, the side plates 2 at the lower left and right ends of the fixed frame 1 play a supporting and auxiliary role in installation. The mounting holes 6 at the upper and lower front ends of the fixed frame 1 are used for installation at the front end of the forklift.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
