Description

Technical Field

[0001] This utility model relates to the field of steering axles, specifically a steering axle for an empty container stacker. Background Technology

[0002] In ports, logistics warehouses and other places, empty container stackers are the core equipment for achieving efficient stacking and transfer of containers. The performance of their steering axles directly affects the equipment's operational flexibility and efficiency.

[0003] Traditional empty container stacker steering axles often employ a complex integrated installation structure for the steering cylinder and axle body, or are placed in confined spaces or hard-to-reach locations. When the steering cylinder experiences malfunctions such as aging seals, hydraulic leaks, or mechanical wear requiring repair, operators often need to use various specialized tools to dismantle numerous connected pipes, supports, and other components. This not only consumes a significant amount of time and manpower but also easily damages surrounding parts during disassembly, making it difficult to conduct inspection and maintenance of the steering cylinder smoothly. Therefore, it is necessary to design a new steering axle for empty container stackers to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a steering axle for an empty container stacker to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steering axle for an empty container stacker, comprising a body and a steering cylinder placed inside the body, a support seat installed inside the body, an adapter groove formed on the surface of the support seat, the steering cylinder passing through the adapter groove, and two limiting plates installed on the outside of the steering cylinder, the top surface of the limiting plates having a slot.

[0006] Two telescopic rods are installed on the top of the inner side of the machine body. The lower ends of the two telescopic rods are fixedly installed with locking blocks. The locking blocks pass through two locking slots. A limiting component for pressing down the locking blocks is installed on the inner side of the machine body.

[0007] Preferably, the limiting component includes two movable rods that move through the machine body. One end of each movable rod is fixedly fitted with a pressure block for pressing down on the locking block, and an adjusting component is installed on one side of the pressure block.

[0008] Preferably, the adjusting component is a threaded rod, which is rotatably mounted on one side of the pressure block. The threaded rod is threaded through the machine body, and a knob is fixedly mounted on one end of the threaded rod.

[0009] Preferably, the inner surface of the adapter groove is a curved surface that fits the outer side of the steering cylinder.

[0010] Preferably, the spacing between the two limiting plates is appropriately matched with the width of the support base, and the two limiting plates are respectively located on both sides of the support base.

[0011] Preferably, the card block has a rectangular cross-section, and the width of the card block is appropriately matched with the width of the card slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The steering axle of this empty container stacker rotates by turning the knob, causing the threaded rod to rotate and the two pressure blocks to move away from each other. The pressure blocks move to a position where they do not block the locking block, thus preventing the locking block from being pressed into the locking groove. Then, the steering cylinder moves upward, causing the steering cylinder and the limit plate to push the locking block upward a certain distance, so that the steering cylinder disengages from the adapter groove and the limit plate does not block the side of the support base. Pulling the steering cylinder to the side further will disengage the steering cylinder from the machine body, making it easy to remove the steering cylinder for inspection or replacement.

[0014] 2. During installation of the steering axle of this empty container stacker, the steering cylinder is placed inside the adapter slot, with two limit plates located on both sides of the support base, ensuring that the slots on the surface of the limit plates face the locking block. The locking block is then inserted into the slot, and the knob is turned to rotate the threaded rod, causing the pressure block to press the locking block into the slot. The locking block has a limiting effect on the rotation angle of the limit plate, and the limit plate has a horizontal limiting effect on the steering cylinder, thus completing the installation of the steering cylinder. It is easy to install and remove, and easier to maintain. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] Example 1

[0022] Please refer to Figure 1-4 As shown, this utility model provides a steering axle for an empty container stacker, including a body 1 and a steering cylinder 4 placed inside the body 1. A support seat 2 is installed inside the body 1, and an adapter groove 3 is opened on the surface of the support seat 2. The steering cylinder 4 passes through the adapter groove 3. Two limiting plates 5 are installed on the outside of the steering cylinder 4, and a slot 6 is opened on the top surface of the limiting plate 5.

[0023] Two telescopic rods 7 are installed on the top inner side of the body 1. The lower ends of the two telescopic rods 7 are fixedly installed with locking blocks 8. The locking blocks 8 pass through two locking slots 6. A limiting component for pressing the locking blocks 8 is installed on the inner side of the body 1.

[0024] Specifically, the fixed state of the locking block 8 is changed by the limiting component, which makes it easier to fix or remove the steering cylinder 4, making the steering cylinder 4 easy to maintain and replace.

[0025] The limiting component includes two movable rods 9, which movably pass through the machine body 1. One end of each movable rod 9 is fixedly installed with a pressure block 10 for pressing down the locking block 8. An adjusting component is installed on one side of the pressure block 10, specifically a threaded rod 11. The threaded rod 11 is rotatably installed on one side of the pressure block 10 and threaded through the machine body 1. One end of the threaded rod 11 is fixedly installed with a knob 12. Rotating the knob 12 drives the threaded rod 11 to rotate, thereby facilitating the movement of the pressure block 10 and changing the state in which the pressure block 10 presses down on the locking block 8.

[0026] Among them, the inner surface of the adapter groove 3 is a curved surface that fits the outer side of the steering cylinder 4, so that the steering cylinder 4 can be inserted into the adapter groove 3.

[0027] Specifically: the distance between the two limiting plates 5 is appropriately matched with the width of the support base 2. The two limiting plates 5 are located on both sides of the support base 2. The two limiting plates 5 block both sides of the support base 2, so that when the steering cylinder 4 is inside the adapter groove 3, it cannot move along the axial direction of the steering cylinder 4, thus achieving the limiting effect.

[0028] Wherein: the cross-section of the locking block 8 is rectangular, and the width of the locking block 8 is appropriately matched with the width of the locking groove 6. The locking block 8 is used to press down the limiting plate 5, thereby preventing the steering cylinder 4 from disengaging from the adapter groove 3.

[0029] Working principle: This utility model is a steering axle for an empty container stacker. When the steering cylinder 4 needs maintenance, the bolts between the output ends of the steering cylinder 4 and the steering knuckle transmission rod are removed, so that the output ends of the steering cylinder 4 are separated from the steering knuckle transmission rod. This part is exposed and easy to operate. Then, the knob 12 is turned to drive the threaded rod 11 to rotate, so that the two pressure blocks 10 move away from each other. The pressure blocks 10 move to a position that does not block the locking block 8, so that the locking block 8 is not pressed into the inner side of the locking groove 6. Then, the steering cylinder 4 is moved upward, so that the steering cylinder 4 and the limiting plate 5 push the locking block 8 upward a certain distance, so that the steering cylinder 4 is disengaged from the adapter groove 3, and the limiting plate 5 does not block the side of the support seat 2. Then, the steering cylinder 4 is pulled to the side, so that the steering cylinder 4 is disengaged from the machine body 1, making it easy to remove the steering cylinder 4 for inspection or replacement.

[0030] During installation, the steering cylinder 4 is placed inside the adapter slot 3, with the two limiting plates 5 located on both sides of the support base 2, and the slots 6 on the surface of the limiting plates 5 facing the locking block 8. The locking block 8 is inserted into the slot 6, and the knob 12 is rotated to drive the threaded rod 11 to rotate, so that the pressure block 10 presses the locking block 8 into the slot 6. The locking block 8 has a limiting effect on the rotation angle of the limiting plate 5, and the limiting plate 5 has a horizontal limiting effect on the steering cylinder 4, thus completing the installation of the steering cylinder 4. It is easy to disassemble and assemble, and easier to maintain.
