Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, and in particular relates to a forklift truck. Background Technology

[0002] Forklifts are material handling equipment widely used in warehousing, logistics, manufacturing and other fields. They are mainly used for indoor loading, unloading, stacking and handling operations. Forklifts are highly flexible and can move shelves in both horizontal and vertical directions, which greatly improves work efficiency and reduces the labor intensity of workers.

[0003] However, when using existing forklifts, the operator first observes the position of the bucket and the shelf, and then starts the forklift to move the bucket to the position under the shelf. However, the traditional way of grabbing the shelf requires the operator to rely on their own sense. When the operator makes a mistake, the shelf being grabbed will shift, which will affect the difficulty of stacking the shelf and thus make stacking difficult.

[0004] In other words, traditional loading and unloading methods require workers to operate based on their own senses, which can cause the stacked shelves to shift, thus affecting their stability. Utility Model Content

[0005] This utility model addresses the problem in existing technologies where traditional loading and unloading methods require operators to rely on their own intuition, leading to shelf misalignment after stacking and affecting the stability of the stacked shelves. The following technical solution is proposed:

[0006] A forklift truck, comprising:

[0007] Forklifts are equipped with buckets for grabbing shelves;

[0008] Drive component one is connected to the forklift and is used to drive the bucket movement;

[0009] The detection component includes a mounting base, an angle adjustment component, a rotating shaft, a connecting plate, and a detection element. The mounting base is perpendicular to the first drive component and is connected to the first drive component. The connecting plate and the detection element are connected to the mounting base via the rotating shaft, and are used to observe the angle change between the bucket and the shelf.

[0010] As a preferred embodiment of the above technical solution, the angle adjustment assembly includes: a linkage component and a linkage rod. The linkage rod is connected inside the mounting base and to the linkage component. The linkage component drives the rotating shaft to rotate under the drive of the linkage rod. A second driving component is provided on the linkage rod for driving the linkage rod to rotate. A limit ring is sleeved on the linkage rod, and the second driving component is connected to the mounting base through the limit ring.

[0011] As a preferred embodiment of the above technical solution, two connecting plates are provided, with the two connecting plates located on both sides of the linkage member, and the opposite sides of the two connecting plates respectively abutting against both sides of the linkage member to restrict the rotation state of the linkage member.

[0012] As a preferred embodiment of the above technical solution, wear-resistant strips are provided on the opposite side of the connecting plates on both sides and on both sides of the linkage component.

[0013] As a preferred embodiment of the above technical solution, the driving component 2 is provided with a first conveying pipe and a second conveying pipe. The first conveying pipe is connected to the driving component 2 in a horizontal direction, and the second conveying pipe is connected to the driving component 2 in a vertical direction. The other end of the first conveying pipe is connected to a cavity and a push rod. The cavity is sleeved on the push rod, and the other end of the push rod is connected to a positioning ring. The positioning ring is sleeved on the driving component 1.

[0014] As a preferred embodiment of the above technical solution, the other end of the second driving component is connected to a liquid collection box, the liquid collection box is provided with a positioning block, the liquid collection box is connected to the mounting base through the positioning block, a baffle is provided inside the liquid collection box, and the same elastic element is provided between the baffle and the liquid collection box.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) The cross marks are marked on the object by the detection piece and imaged into the cab of the forklift, which makes it easier for the staff to adjust the angle between the bucket and the object. This avoids the problem of the angle between the shelf and the bucket shifting when the staff grabs the shelf by feeling, thus improving the stability of the stacked shelf.

[0017] (2) By activating the drive unit, the detection unit is made to be in a vertical or inclined state, which effectively improves the detection range of the detection unit. When the bucket is in a horizontal state, the detection unit is in an inclined state, which can effectively detect the contact position between the bucket and the shelf. Conversely, when the detection unit is in a vertical state, it can effectively detect the horizontal position between the bucket and the shelf, thus making the shelf pulled by the bucket more stable.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Example 1

[0026] This utility model provides a forklift truck, such as Figures 1 to 5 As shown, the system includes: a forklift 1, a drive unit 2, and a detection assembly. The forklift 1 is equipped with a bucket for grabbing shelves. The drive unit 2 is connected to the forklift 1 and drives the bucket. An imaging device is installed inside the forklift 1. The drive unit 2 is a hydraulic rod. The detection assembly includes a mounting base 3, an angle adjustment assembly, a rotating shaft 4, a connecting plate 5, and a detection element 6. The detection element 6 is a crosshair camera and is electrically connected to the imaging device inside the forklift 1. The mounting base 3 is perpendicular to the drive unit 2 and is composed of a ring and a cylinder. The ring part is fitted onto the outer surface of the drive unit 2, and the cylindrical part is fixed. The mounting base 3 is connected to the drive component 2, and the connecting plate 5 and the detection component 6 are connected to the mounting base 3 via the rotating shaft 3 for observing the angle change between the bucket and the shelf. There are two connecting plates 5, which are located on both sides of the linkage component 7, and the opposite side of the two connecting plates 5 is in contact with the two sides of the linkage component 7 to limit the rotation of the linkage component 7. The top of the mounting base 3 is provided with two grooves, and the two connecting plates 5 are slidably connected to the two grooves. Wear-resistant strips are provided on the opposite side of the two connecting plates 5 and the two sides of the linkage component 7. The wear-resistant strips are made of rubber to prevent the connecting plates 5 from directly contacting the linkage component 7.

[0027] The detection component 6 marks the object with crosshairs and projects the image into the cab of the forklift 1, making it easier for the operator to adjust the angle between the bucket and the object. This avoids the problem of the angle between the shelf and the bucket shifting when the operator grabs the shelf by feeling, thus improving the stability of the stacked shelf.

[0028] When moving a shelf from the ground, the operator first enters the cab of the forklift 1, then turns on the imaging device. The image, identified by the detector 6, is marked with crosshairs and displayed on the imaging device. The operator then drives the forklift 1, observing the image on the imaging device in real time to control its angle. The forklift 1 aligns the bucket with the shelf. The operator then activates drive component 2, which rotates the bucket. When the bucket is horizontally aligned with the shelf, the operator starts the forklift 1, moving the bucket under the shelf. The operator then reverses drive component 2 to lift the shelf and places it in the designated area, completing the shelf relocation process. The detector 6 marks the object with crosshairs and projects the image into the cab of the forklift 1, allowing the operator to adjust the angle between the bucket and the object. This avoids the problem of the angle between the shelf and bucket shifting when the operator relies on their own judgment to grasp the shelf, thus improving the stability of the stacked shelf.

[0029] Specifically, a drive component 2 is fixedly connected to the top of the forklift 1. A mounting base 3 is sleeved on the surface of the drive component 2 and fixedly connected to the drive component 2. A rotating shaft 4 is rotatably connected to the top of the inside of the mounting base 3. A connecting plate 5 is fixedly connected to the surface of the rotating shaft 4. A detection component 6 is fixedly connected to the top of the connecting plate 5.

[0030] The working principle and operation steps of the forklift 1 described in the above examples are existing technologies in this field, and will not be elaborated further here.

[0031] To achieve the goal of adjusting the detection angle of the detection component 6 in the above example, the following solution is proposed: Figures 2 to 5As shown, the angle adjustment assembly includes: a linkage 7 and a linkage rod 8. The linkage rod 8 is connected inside the mounting base 3. The linkage 7 is a worm gear, and the linkage rod 8 is a worm shaft. The linkage rod 8 meshes with the linkage 7. The linkage 7 drives the rotating shaft 4 to rotate under the drive of the linkage rod 8. A second driving component 9 is provided on the linkage rod 8 to drive the linkage rod 8 to rotate. The second driving component 9 is a gear pump. A limit ring is sleeved on the linkage rod 8, and the linkage rod 8 rotates inside the limit ring. The second driving component 9 is fixedly connected to the mounting base 3 through the limit ring. The second driving component 9 is provided with a first conveying pipe 10 and a second conveying pipe 11. The first conveying pipe 10 is horizontally connected to the second driving component 9, and the second conveying pipe 11 is vertically connected to the second driving component 9. The other conveying pipe 10... One end is connected to a cavity 12 and a push rod 13. The surface of the cavity 12 fits against the inner wall of the push rod 13. The cavity 12 is sleeved on the push rod 13. The other end of the push rod 13 is connected to a positioning ring 14, which is sleeved on the drive component 2 and connected to the output end of the drive component 2. The other end of the drive component 2 is connected to a liquid collection box 15. The liquid collection box 15 is provided with a positioning block 16. The bottom of the liquid collection box 15 has an air vent. The liquid collection box 15 is fixedly connected to the mounting base 3 through the positioning block 16. The liquid collection box 15 is provided with a baffle 17 inside. The surface of the baffle 17 fits against the inner wall of the liquid collection box 15. The same elastic element 18 is provided between the baffle 17 and the liquid collection box 15. The elastic element 18 is a spring.

[0032] By activating the drive unit 2, the detection unit 6 is made to be in a vertical or tilted state, which effectively improves the detection range of the detection unit 6. When the bucket is horizontal, the detection unit 6 is tilted, which can effectively detect the contact position between the bucket and the shelf. Conversely, when the detection unit 6 is vertical, it can effectively detect the horizontal position between the bucket and the shelf, thus making the shelf pulled by the bucket more stable.

[0033] In operation, when the bucket is horizontal, the output end of the drive unit 2 moves the positioning ring 14. The positioning ring 14 moves the push rod 13 inside the moving cavity 12, drawing out the liquid from the liquid collection box 15. At this time, the liquid in the liquid collection box 15 flows into the conveying pipe 11 through the cooperation of the elastic element 18 and the baffle 17, and then enters the drive unit 9 along the conveying pipe 11. It then flows along the internal parts of the drive unit 9 to the conveying pipe 10. Subsequently, the liquid enters the cavity 12 along the conveying pipe 10. While flowing inside the drive unit 9, the liquid causes the internal parts of the drive unit 9 to rotate. The internal parts of the drive unit 9 drive the linkage rod 8 to rotate, the linkage rod 8 drives the linkage element 7 to rotate, the linkage element 7 drives the rotating shaft 4 and the connecting plate 5 to rotate synchronously, and the connecting plate 5 drives the detection element 6. When the bucket is horizontal, the detection element 6 tilts, ensuring its detection range is precisely at the bucket's position. Reversing this process, the cavity 12 flows into the liquid collection box 15, causing the baffle 17 to move downwards. During this downward movement, the elastic element 18 deforms, allowing gas inside the liquid collection box 15 to escape through the vent. This causes the components inside the drive unit 9 to rotate in the opposite direction, making the detection element 6 vertical. Activating the drive unit 2 allows the detection element 6 to be either vertical or tilted, effectively increasing its detection range. When the bucket is horizontal, the tilted detection element 6 effectively detects the contact position between the bucket and the shelf; conversely, the vertical detection element 6 effectively detects the horizontal position of the bucket and the shelf, thus making the shelf pulled by the bucket more stable.

[0034] Specifically, the linkage rod 8 is rotatably connected to the inside of the mounting base 3. The surface of the linkage rod 8 is engaged with the linkage component 7, which is fixedly connected to the surface of the rotating shaft 4. The linkage component 7 is located on one end face opposite to the two connecting plates 5. The second driving component 9 is fixedly connected to the surface of the mounting base 3. The parts inside the second driving component 9 are fixedly connected to the surface of the linkage rod 8. The bottom end of the second driving component 9 is embedded with the second conveying pipe 11. The bottom end of the second conveying pipe 11 is fixedly connected to the liquid collection box 15. The inside of the liquid collection box 15 is slidably connected with the baffle 17. The bottom end of the baffle 17 and the bottom end of the inside of the liquid collection box 15 are fixedly connected with the same elastic component 18. The side of the liquid collection box 15 is fixedly connected with the positioning block 16, which is fixedly connected to the surface of the mounting base 3. The side of the second driving component 9 is embedded with the first conveying pipe 10. The other end of the first conveying pipe 10 is fixedly embedded with the cavity 12. The inside of the cavity 12 is slidably connected with the push rod 13. The other end face of the push rod 13 is fixedly connected with the positioning ring 14, which is fixedly connected to the output end of the first driving component 2.

[0035] Working Principle: When the ground-level shelves need to be moved, the operator first enters the cab of the forklift 1, then turns on the imaging device. This allows the image, identified by the detector 6, to be marked with crosshairs and displayed on the imaging device. The operator then drives the forklift 1, observing the image on the imaging device in real time to control the angle of the forklift 1, ensuring the bucket is aligned with the shelf. The operator then activates drive component 2, which rotates the bucket. When drive component 2 has the bucket in a horizontal position, the output of drive component 2... The outlet drives the positioning ring 14 to move, which in turn drives the push rod 13 to move inside the moving cavity 12, drawing out the liquid from the liquid collection box 15. At this time, the elastic element 18, in cooperation with the baffle 17, drives the liquid inside the liquid collection box 15 to flow into the second conveying pipe 11, and then into the second driving element 9. From there, the liquid flows along the internal components of the second driving element 9 to the first conveying pipe 10. Subsequently, this liquid flows along the first conveying pipe 10 into the cavity 12. As this liquid flows inside the second driving element 9, it causes the internal components of the second driving element 9 to rotate. The internal components of drive component 9 drive linkage rod 8 to rotate, linkage rod 8 drives linkage component 7 to rotate, linkage component 7 drives shaft 4 and connecting plate 5 to rotate synchronously, and connecting plate 5 drives detection component 6 to rotate. When the bucket is in a horizontal state, the detection component 6 tilts, so that the detection range of detection component 6 is exactly at the position of the bucket. Reversing the above steps, the cavity 12 flows into the liquid collection box 15, and drives baffle 17 to move down. During the downward movement of baffle 17, the elastic component 18 is deformed. At this time, the gas inside the liquid collection box 15 is discharged through the vent, and drive drive component 9. The internal parts rotate in the opposite direction, making the detection component 6 vertical. Then, the operator starts the forklift 1, moving the bucket to the bottom of the shelf. At this time, the operator reverses the drive component 2 to lift the shelf and then places it in the preset area, thus completing the shelf relocation process. The detection component 6 marks the object with a crosshair and projects an image into the cab of the forklift 1, making it easier for the operator to adjust the angle between the bucket and the object. This avoids the problem of the angle between the shelf and the bucket shifting when the operator grabs the shelf by feeling, thus improving the stability of the stacked shelf.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
