Description

Technical Field

[0001] The embodiments of this utility model relate to the field of stacker technology, specifically to a stacker based on a stable guiding mechanism. Background Technology

[0002] In the fields of warehousing, logistics, and industrial material handling, forklifts are key equipment for achieving efficient cargo transfer and stacking. They often need to operate in complex conditions such as ramps inside warehouses and sloping surfaces in outdoor loading and unloading areas. To adapt to the passage requirements of obstacles of varying heights or uneven road surfaces in these scenarios, forklifts are usually equipped with specialized telescopic components. By raising and lowering the entire vehicle body, the ground clearance of the chassis can be adjusted, thereby significantly enhancing the vehicle's ability to pass through complex road conditions and ensuring that the transportation of goods is not limited by road conditions.

[0003] However, in existing stacker trucks, when the telescopic components drive the body assembly to rise and fall, the lack of an effective guiding and limiting structure makes the telescopic rod susceptible to uneven stress due to various factors. This results in the extension direction being inconsistent with the preset rising direction of the body assembly. For example, road bumps generated when driving on a slope are directly transmitted to the telescopic components, causing the telescopic rod to become unbalanced and deviate from the preset direction. Uneven load caused by the offset of the cargo placement position will cause the body to bear a biased force. This biased force is transmitted to the telescopic rod, forcing the extension direction of the telescopic rod to deviate. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a stacker truck based on a stable guiding mechanism, which solves the technical problem that the telescopic rod is subjected to uneven force after the telescopic component is affected by factors such as road bumps and load shifts, resulting in the extension direction being inconsistent with the preset upward direction of the vehicle body components.

[0005] According to one aspect, at least one embodiment of the present invention provides a stacker truck based on a stabilizing guide mechanism, comprising:

[0006] Frame,

[0007] A vehicle body assembly, which is elliptically mounted on the vehicle frame, includes liftable forks and vertically mounted baffles, the forks being used to carry goods;

[0008] Telescopic component one, the telescopic component one is disposed on the vehicle frame, the telescopic component one has a telescopic rod one, the telescopic rod one is used to drive the body assembly to rise and fall;

[0009] A guide frame is disposed on the telescopic member 1, and the guide frame has a guide portion for abutting against the baffle.

[0010] For example, in a stacker truck based on a stable guiding mechanism provided in at least one embodiment of the present invention, the guiding part is a guide wheel rotatably mounted on the guide frame, and the guide wheel can roll and abut against the baffle when the vehicle body assembly is raised or lowered.

[0011] For example, in a stacker truck based on a stable guiding mechanism provided in at least one embodiment of the present invention, the end of the telescopic rod is provided with a top plate, the top plate is connected to the vehicle body assembly, a guide slot is provided on the side of the top plate away from the baffle, and a support rod extending vertically is provided on the vehicle frame, the support rod being used to abut against the guide slot.

[0012] For example, in a stacker truck based on a stabilizing guide mechanism provided in at least one embodiment of this utility model, the vehicle body assembly further includes:

[0013] A protective cover, which is raised and mounted on the vehicle frame, with the baffle and the telescopic component both located inside the protective cover;

[0014] An outer mast is mounted on the base plate of the protective cover and located outside the protective cover, and the fork lifting mechanism is mounted on the outer mast.

[0015] For example, in a stacker truck based on a stabilizing guide mechanism provided in at least one embodiment of the present invention, the vehicle body assembly further includes an inner mast, which is ellipsably mounted on the outer mast, and the forks are ellipsably mounted on the outer mast via the inner mast.

[0016] For example, in a stacker truck based on a stabilizing guide mechanism provided in at least one embodiment of the present invention, the vehicle body assembly further includes a second telescopic member, which is disposed on the base plate and is used to drive the inner mast to rise and fall.

[0017] For example, in a stacker truck based on a stable guiding mechanism provided in at least one embodiment of this utility model, a hydraulic cylinder fixing seat is provided at the upper end of the outer mast, and the hydraulic cylinder fixing seat is used to fix the telescopic member two.

A sprocket seat is provided on the inner mast, and the end of the sprocket seat is connected to the telescopic end of the telescopic member two. A sprocket for tensioning the chain is rotatably disposed on the sprocket seat.

[0019] For example, in a stacker truck based on a stable guiding mechanism provided in at least one embodiment of the present invention, the forks include horizontally distributed load-bearing parts and vertical stop parts connected to the load-bearing parts.

[0020] For example, in a stacker truck based on a stabilizing guide mechanism provided in at least one embodiment of the present invention, the vehicle body assembly is provided with a drive handle, which is used to control the first telescopic member and the second telescopic member.

[0021] The beneficial effects of the embodiments of this utility model are as follows:

[0022] The guide frame's guide section engages with the baffle of the vehicle body assembly, providing stable guidance and constraint for the telescopic rod of the telescopic component. When the telescopic rod drives the vehicle body assembly to rise or fall, the continuous engagement between the guide section and the baffle effectively corrects directional deviations caused by road bumps, load shifts, and other factors, ensuring that its extension direction is consistent with the preset upward direction of the vehicle body assembly. This results in balanced force distribution on the telescopic rod, reduced wear, extended equipment lifespan, and improved operational safety and reliability of the stacker truck during cargo stacking operations.

[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] like Figures 1-4 As shown, it illustrates a stacker truck based on a stabilizing guide mechanism in one embodiment of the present invention.

[0036] In some examples, the frame 1 is horizontally positioned, serving as the basic load-bearing structure of the stacker. The body assembly 2 is capable of lifting and lowering relative to the frame 1. Forks 21 are horizontally positioned at the front of the body assembly 2, and a baffle 22 is vertically fixed to the side of the body assembly 2 near the telescopic member 23. The telescopic member 23 is fixedly installed in the middle of the frame 1, with its telescopic rod 2301 extending vertically. The top of the telescopic rod 2301 is connected to the body assembly 2. When the telescopic rod 2301 extends or retracts, it causes the body assembly 2 to lift and lower along the frame 1. A guide frame 24 is fixed to the outside of the cylinder of the telescopic member 23, and a guide portion 2401 protrudes from the guide frame 24 towards the baffle 22. During the lifting and lowering of the body assembly 2, the guide portion 2401 remains in contact with the surface of the baffle 22. When the telescopic component 23 drives the body assembly 2 to rise and fall, the contact force between the guide part 2401 and the baffle 22 forms a constraint, which can correct the directional deviation of the telescopic rod 2301 caused by external force interference, ensure that its extension direction is consistent with the preset upward direction of the body assembly 2, limit the body assembly 2 from deviating from the vertical trajectory, and avoid uneven force on the telescopic rod 2301 caused by directional deviation. The structural cooperation of each component forms a complete guiding system, which effectively solves the problem of the extension direction of the telescopic rod 2301 being inconsistent with the upward direction during the raising and lowering of the body assembly 2, and ensures the reliable operation of the stacker truck under complex road conditions.

[0037] The guide part 2401 is a guide wheel, which is rotatably mounted on the guide frame 24 via an axle. The axle is set in the horizontal direction, and the outer circumferential surface of the guide wheel contacts the surface of the baffle 22. When the body assembly 2 is raised or lowered, the guide wheel rotates with the movement of the baffle 22, achieving rolling contact. This structure converts the sliding friction between the guide part 2401 and the baffle 22 into rolling friction, reducing wear between the two and reducing the resistance when the body assembly 2 is raised or lowered, making the raising and lowering action smoother. When the body assembly 2 is raised or lowered, the guide wheel rolls against the baffle 22, limiting the horizontal swing of the telescopic member 23. This reduces the risk of bending and deformation of the telescopic rod 2301 due to additional lateral forces. For example, when improving the chassis passability on complex road conditions such as slopes, the slope and unevenness of the road surface will cause the stacker to bump and impact. This impact is transmitted to the telescopic member 23, which can easily cause the telescopic rod 2301 to become unbalanced and deviate. The guide wheel design reduces abnormal wear between the piston and cylinder inside the telescopic component 2301, thereby extending the service life of the hydraulic cylinder and ensuring the smoothness and reliability of the hydraulic cylinder's telescopic movement.

[0038] The top plate 25 is horizontally fixed to the top of the telescopic rod 2301. The edge of the top plate 25 is connected to the body assembly 2. The guide slot 2501 is opened along the edge of the top plate 25, and its cross-sectional shape is adapted to the cross-sectional shape of the support rod 11. The support rod 11 is vertically fixed to the frame 1 and extends vertically to the travel range of the guide slot 2501. When the body assembly 2 is raised or lowered, the support rod 11 is always embedded in the guide slot 2501 and abuts against the inner wall of the slot. The cooperation between the guide slot 2501 and the support rod 11 forms a second layer of guiding constraint, which, together with the cooperation of the guide part 2401 and the baffle 22, further restricts the lateral displacement of the telescopic member 2301 and improves the stability of the raising and lowering process.

[0039] The protective cover 26 has a box-like structure. The baffle 22 and the telescopic component 23 are both located inside the cavity of the protective cover 26. The outer mast 27 is vertically fixed to the outside of the bottom plate of the protective cover 26. The forks 21 are connected to the outer mast 27 through a sliding structure. The protective cover 26 protects the baffle 22 and the telescopic component 23, preventing external debris from interfering with their operation. The outer mast 27 provides guidance for the lifting and lowering of the forks 21, ensuring that the lifting and lowering of the forks 21 is independent of and does not interfere with the lifting and lowering of the vehicle body assembly 2.

[0040] The inner mast 28 is fitted inside the outer mast 27 via a slide rail. The forks 21 are fixed to the front end of the inner mast 28, and the inner mast 28 can be raised and lowered along the vertical direction of the outer mast 27. The second telescopic component 29 is fixed to the upper surface of the bottom plate of the protective cover 26, and its second telescopic rod extends vertically and connects to the bottom of the inner mast 28. The cooperation between the inner mast 28 and the outer mast 27 provides a more stable guide for the raising and lowering of the forks 21. The second telescopic component 29 serves as the power source for the raising and lowering of the forks 21, driving the inner mast 28 to raise and lower the forks 21, thereby adjusting the height of the forks 21 to meet different stacking operation requirements.

[0041] The cylinder mounting base 3 is fixed to the top of the outer gantry 27. The top of the cylinder body of the telescopic component 29 is connected to the cylinder mounting base 3 by bolts, making the installation of the telescopic component 29 more stable and preventing it from shaking when driving the inner gantry 28 to rise and fall.

[0042] One end of chain 4 is fixedly connected to the bottom of cylinder mounting base 3, and the other end passes over sprocket 6 and is bolted to the fork carriage of fork 21. Sprocket 6 is rotatably mounted on sprocket seat 5 via axle. Sprocket seat 5 is fixed to the top of inner mast 28, and the end of sprocket seat 5 is connected to the top of telescopic rod 29. When telescopic rod 29 drives sprocket seat 5 to rise or fall, sprocket 6 drives chain 4 to move, thereby realizing the rising and falling of fork 21. Chain 4 transmission makes the rising and falling of fork 21 more stable, and the tension of sprocket 6 ensures the reliability of chain 4 transmission.

[0043] The fork 21 has a horizontally extending support portion 2101, with its front end used to insert into the bottom of the cargo. A vertical stop portion 2102 is vertically fixed to the rear end of the support portion 2101, forming an L-shaped structure. The support portion 2101 provides a support surface for the cargo, and the vertical stop portion 2102 blocks the rear end of the cargo, preventing the cargo from slipping off the rear end of the fork 21 during the movement or lifting of the stacker.

[0044] The drive handle 7 is rotatably mounted on the side of the vehicle body assembly 2. It contains a control circuit and is connected via wires to the control terminals of telescopic component 1 23 and telescopic component 29. By rotating the drive handle 7, the operator can control the extension and retraction of the telescopic rods of telescopic component 1 23 and telescopic component 29, enabling convenient control of the lifting and lowering movements of the vehicle body assembly 2 and the forks 21, thus improving operational efficiency.

[0045] In this embodiment, when the stacker truck is in use, the operator controls the telescopic component 23 (in this example, the telescopic component 23 can be a hydraulic cylinder) by driving the handle 7. By operating the handle 7, the hydraulic cylinder telescopic rod is extended, causing the top plate 25 to rise, which in turn drives the body assembly 2 to rise along the frame 1. During this process, the guide wheel of the guide frame 24 and the baffle 22 continuously abut against each other, and the guide slot 2501 of the top plate 25 slides along the support rod 11, which together constrains the stable lifting and lowering of the body assembly 2 until the required chassis height is reached.

[0046] During cargo stacking operations, the drive handle 7 controls the telescopic component 29 (in this example, the telescopic component 29 can be a hydraulic cylinder). Its telescopic rod 2301 extends and retracts, causing the inner mast 28 to rise and fall along the outer mast 27. The inner mast 28, through the sprocket 6 seat 5, sprocket 6, and chain 4, drives the forks 21 to rise and fall. The bearing portion 2101 of the forks 21 inserts into the bottom of the cargo, and the vertical stop 2102 blocks the cargo. After the forks 21 rise to the target height, the stacker truck is moved to place the cargo in position, and then the operation is reversed to lower the forks 21 back to their original position. If it is necessary to lower the chassis, the drive handle 7 is operated to shorten the hydraulic cylinder telescopic rod of the telescopic component 23, causing the chassis assembly 2 to descend along the frame 1. The guide structure continuously ensures stability. After the operation is completed, all components are reset.
