Description

Technical Field

[0001] The invention relates to the technical field of stacker trucks, and in particular to a transversely movable stacker truck. Background Art

[0002] In traditional warehousing operations, pallet stackers are commonly used handling equipment. However, traditional pallet stackers need to turn to change the direction of travel during operation. This feature leads to higher requirements for channel width. In order to meet the turning requirements of stackers, warehouses usually need to set up wider channels, which to a certain extent wastes precious storage space and reduces space utilization. In addition, traditional pallet stackers have a low chassis and have high requirements for the working road surface. Once they encounter uneven roads, their operating capabilities will be greatly affected. For example, the front legs of the pallet stacker cannot operate when encountering tires or double-sided pallets, which greatly limits its scope of application. With the rapid development of the logistics industry and the continuous increase in warehousing needs, improving warehouse space utilization and improving operating efficiency have become issues that need to be urgently addressed.

[0027] like Figure 1As shown, a transversely movable stacker includes a chassis 1, a base plate 4 is installed at the bottom position of the front end of the chassis 1, a lifting guide frame 5 is installed on the upper end of the base plate 4, a lifting frame 6 is slidably installed on the lifting guide frame 5, and an attachment 7 is installed at the front end of the lifting frame 6. The lifting operation of the lifting frame 6 on the lifting guide frame 5 belongs to the common knowledge in the field and will not be repeated here. A telescopic leg mechanism is installed at the bottom of the base plate 4, and telescopic support legs 8 are symmetrically installed at both ends of the telescopic leg mechanism. Travel wheels 9 and driven wheels 34 are distributed and installed at the ends of the left and right telescopic support legs 8, and the travel wheels 9 are connected to the steering rod 18 through a steering mechanism.

[0028] like Figure 2 As shown, the telescopic leg mechanism includes a slide 10 and a slide 2 14 which are installed in parallel at the lower end of the base plate 4. The slide 10 and the slide 2 14 are respectively slidably installed with a telescopic mechanism 11 and a telescopic mechanism 2 15 which are fixedly connected to the telescopic support leg 8. The telescopic mechanism 11 and the telescopic mechanism 2 15 are symmetrically distributed to meet the lateral telescopic demand of the telescopic support leg 8. The end of the slide 10 away from the telescopic mechanism 1 11 is installed with a cylinder 1 mounting seat 13, and the cylinder 1 mounting seat 13 and the telescopic mechanism 1 11 are connected together through the cylinder 1 12. The end of the slide 2 14 away from the telescopic mechanism 2 15 is installed with a cylinder 2 mounting seat 17, and the cylinder 2 mounting seat 17 and the telescopic mechanism 2 15 are connected together through the cylinder 2 16. Specifically, during the actual operation, according to the actual situation, the oil cylinder 12 can be started to realize the extension and retraction of the telescopic supporting leg 8 on the left side; the oil cylinder 2 16 can be started to realize the extension and retraction of the telescopic supporting leg 8 on the right side; and the oil cylinder 12 and the oil cylinder 2 16 can be started at the same time to realize the synchronous extension and retraction of the telescopic supporting legs 8 on both sides. In this way, obstacles such as tires can be effectively avoided, and operations can be carried out smoothly regardless of whether it is a double-sided pallet or a single-sided pallet.

[0029] like Figure 3-5As shown, the steering mechanism includes a turntable 19 connected to the steering rod 18 by a key, the turntable 19 is hingedly connected to a connecting rod 20, the other end of the connecting rod 20 is hingedly connected to a push rod 21, and the push rod 21 is vertically distributed with the connecting rod 20. The bottom of the push rod 21 is fixedly connected to a rotating drum 22, and the rotating drum 22 is connected to a U-shaped hinge joint 25 through a crank rocker mechanism, and the other end of the U-shaped hinge joint 25 is installed with a fixing rod 26, and the fixing rod 26 passes through the telescopic mechanism 2 15 and is connected to the telescopic mechanism 27. The crank rocker mechanism includes a prism shaft (23) slidably mounted in the rotating cylinder 22, one end of the prism shaft 23 passing through the rotating cylinder 22 is fixedly connected to the hinge rod 24, and the other end of the hinge rod 24 is hingedly connected to the U-shaped hinge head 25; in this embodiment, the stroke of the prism shaft 23 in the rotating cylinder 22 is greater than the telescopic stroke of the telescopic mechanism 2 15, that is, when the fixed rod 26 moves with the telescopic mechanism 2 15, the prism shaft 23 slides in the rotating cylinder 22 to meet the telescopic demand of the telescopic support leg 8. The other end of the telescopic mechanism 27 is fixedly connected to the rod hinge 28, and the other end of the rod hinge 28 is hingedly connected to the rotating member 29. The telescopic mechanism 27 adopts a cylinder, a hydraulic cylinder or an electric push rod. The center position of the rotating member 29 is hingedly connected to the hinge shaft 1 30, and the end of the rotating member 29 away from the rod hinge 28 is fixedly connected to the wheel axle of the walking wheel 9, which is used to drive the walking wheel 9 to rotate. Bottom plates 32 are symmetrically installed at the upper and lower ends of the hinge shaft 30, and guard plates 31 are installed on the left and right side walls of the bottom plate 32, which mainly serve the purpose of protection. The bottom plate 32 and the guard plate 31 are welded together with the telescopic support leg 8.

[0030] When the steering mechanism is in steering operation, in this embodiment, its rotation angle range is 0 to 25°. In order to prevent the rotating member 29 from rotating at a angle less than 90°, the telescopic mechanism 27 can be extended and retracted a certain distance so that the rotation angle reaches 90°. That is, the telescopic mechanism 27 plays a role in assisting in compensating for the rotation angle in this embodiment.

[0031] The telescopic support leg 8 is a hollow structure, and the telescopic mechanism 27 is placed in the hollow structure and hidden, which plays a role of protection and aesthetics. In addition, in this embodiment, the axle of the driven wheel 33 is also connected to the rotating member 29, and the center position of the rotating member 29 is also hingedly connected to the hinge shaft 1 30. The end of the rotating member 29 away from the driven wheel 33 is hingedly connected to the fixed shaft inside the telescopic support leg 8 near the end of the telescopic mechanism 11 through the support rod. When the walking wheel 9 rotates, it drives the driven wheel to rotate, thereby meeting the need for the stacker to move horizontally.

[0032] A footrest 3 is installed at the bottom of the rear end of the chassis 1 for an operator to step on.

[0033] A handle 2 is mounted on the top of the steering rod 18 for easy operation.

[0034] A driving wheel 33 is installed at the bottom of the steering rod 18, which is a prior art and will not be described in detail here.

[0035] One end of the hinge rod 24 is provided with a special-shaped hole 2401 matching the prism shaft 23 , and the other end is integrally formed with a hinge shaft 2402 matching the U-shaped hinge head 25 .

[0036] One end of the rod hinge 28 is a rod fixedly connected to the telescopic mechanism 27, and the other end is a hinge axis 3 vertically distributed with the rod.

[0037] The rotating member 29 includes a sleeve 2901 located in the middle and hingedly connected to the hinge shaft 30, one end of the sleeve 2901 is an integrally formed bent handle 2902, and the bent handle 2902 is hingedly connected to the rod hinge 28. The other end of the sleeve 2901 is an integrally formed wheel axle connecting rod 2903, and the wheel axle connecting rod 2903 is fixedly connected to the wheel axle of the walking wheel 9.

[0038] In this embodiment, the traveling wheel 9 and the driven wheel 34 are designed with rubber tires, so that they have a higher passing capacity and can adapt to various complex outdoor road conditions.

[0039] The action process of the present invention is as follows:

[0040] Obstacle avoiding operation: start the oil cylinder 12 to realize the extension and retraction of the left telescopic supporting leg 8 to avoid the obstacle on the left; start the oil cylinder 2 16 to realize the extension and retraction of the right telescopic supporting leg 8 to avoid the obstacle on the right; start the oil cylinder 12 and the oil cylinder 2 16 at the same time to realize the synchronous extension and retraction of the telescopic supporting legs 8 on both sides to avoid the obstacles on both sides, and when extending and retracting synchronously, the turning radius is very small, and it can be flexibly operated in a narrow working space.

[0041] Horizontal walking operation: the steering rod 18 rotates clockwise (counterclockwise), and the turntable 19 connected to it by a key rotates clockwise (counterclockwise) by a certain angle, then the connecting rod 20 hingedly connected to the turntable 19 moves backward (forward), and is pushed backward (forward) by the hinged push rod 21, so that the rotating drum 22 drives the prism shaft 23 to rotate counterclockwise (clockwise), and the hinged rod 24 fixedly connected to the prism shaft 23 also rotates counterclockwise (clockwise), and the hinged rod 24 rotationally drives the U-shaped hinged head 25 hingedly connected to it to move forward (backward), and the telescopic mechanism 27 moves forward (backward) together, and the rotating member 29 rotates clockwise (counterclockwise) with the hinge shaft 30 as the center under the action of this forward (backward movement), thereby driving the walking wheel 9 to change the distribution in the X-axis (Y-axis) direction to the Y-axis (X-axis) direction, and can move horizontally (forward and backward) after rotation. After the traveling wheel 9 rotates, it moves together with the driving wheel 33, and the driven wheel 34 naturally changes the rotation direction accordingly, and finally drives the stacker to move together.

[0042] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
