Description

Technical Field

[0001] This invention relates to the technical field of core transmission components for four-way vehicles, specifically as a transmission component used in four-way vehicles to replace the hydraulic and chain structures in traditional four-way vehicles. Background Technology

[0002] As warehouse racking demands higher space utilization, four-way vehicles capable of moving within racking systems have emerged. These vehicles consist of a reduction mechanism, primarily comprising a travel reducer (for X and Y-axis movement) and a lifting reducer (for Z-axis movement). Currently, the travel mechanism employs a structure of "general-purpose reducer + connecting rod + steering gear + sprocket and chain." This design suffers from several drawbacks: the general-purpose reducer is large and overkill; the staggered connecting rods occupy space, resulting in unstable transmission and poor synchronization of the wheels; the open drive of the steering gear is susceptible to dust contamination and requires regular maintenance; and the sprocket and chain experience tension loosening over extended periods, necessitating adjustments, long positioning times, low stability, and easy lubricant leakage. The lifting mechanism uses either hydraulic lifting or rack and pinion lifting. Hydraulic lifting has poor response speed and precision control, high energy consumption due to frequent operation, low efficiency, great influence from ambient temperature, high price of hydraulic components, and the transmission ratio calculation is affected by the physical properties of hydraulic oil, making program control difficult. Rack and pinion structures cannot be sealed, require regular maintenance, are easily contaminated by dust, and grease can easily be splashed out during operation, contaminating the interior space and cargo.

[0003] To address the aforementioned defects and shortcomings, this invention proposes a four-way vehicle speed reducer. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a four-way vehicle speed reducer.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a four-way vehicle reducer, including a support base, two travel reducers I, two travel reducers II, two lifting reducers, a linkage component I, and a linkage component II; The support base has a mounting groove on its top side. Two travel reducers are fixedly mounted on the inner walls of the mounting groove on both sides and arranged symmetrically. Each of the two travel reducers has two output shafts extending to the outside of the support base. The travel reducer is fixedly mounted on the inner wall of the bottom of the mounting groove and has two output shafts arranged symmetrically. Two lifting reducers are fixedly mounted on the inner walls of the front and rear sides of the mounting groove. Each of the two lifting reducers has two output shafts extending to the outside of the support base. The output shafts one and two are used to connect the wheels that support the device to move in the Y direction and in the X direction. The first linkage component is installed on the two travel reducers, and the second linkage component is installed on the two lifting reducers.

[0006] Preferably, the linkage component one includes two coupling slots respectively disposed on the corresponding side of the travel reducer one and power transmission can be achieved through a coupling.

[0007] Preferably, the second linkage component includes two coupling clamps that are rotatably mounted on the corresponding lifting reducer and can be connected by a coupling for transmission.

[0008] Preferably, one of the two is a motor mounting bracket fixedly installed on the travel reducer, which is used to install the motor that provides driving force when controlling the device to move in the Y direction.

[0009] Preferably, a motor mounting base is fixedly installed on the second walking reducer for installing a motor that provides driving force when controlling the device to move in the X direction.

[0010] Preferably, one of the two lifting reducers is fixedly mounted with a motor mounting bracket three for mounting a motor that provides driving force during the lifting operation of the device.

[0011] Preferably, the output shaft three and the lifting reducer are provided with the same eccentric wheel structure.

[0012] Preferably, two stops are fixedly installed on both sides of the support base.

[0013] The walking reducer 1, walking reducer 2, and lifting reducer contain grease and are equipped with seals.

[0014] The beneficial effects of this invention are: This invention features a compact structure and ingenious design. By setting up linkage component one and linkage component two, it can effectively achieve synchronous power transmission, thereby reducing the number of motors, making the overall weight lighter and the number of parts fewer, effectively reducing energy consumption, thereby improving the driving range and reducing the number of failure points, thus reducing the failure rate. Moreover, due to its integrated design, even if a failure occurs, it can be quickly repaired or replaced.

[0015] Meanwhile, the eccentric wheel structure design between the output shaft three and the lifting reducer ensures tight and smooth internal gear transmission, resulting in more stable and reliable lifting operations. This effectively enhances the overall lifting capacity and makes the device suitable for various complex working conditions. In addition, the stop block design on both sides of the support not only enhances the safety of the equipment but also effectively prevents damage to the wheels from external obstacles, further extending the service life of the equipment. The overall transmission structure of this device is not exposed, effectively solving the defects of existing hydraulic lifting machines with gear and rack lifting. These features together improve the working efficiency and practicality of the four-way vehicle reducer, providing a brand-new technical solution for related fields. Attached Figure Description

[0019] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Reference Figure 1-6 A four-way vehicle reducer includes a support base 1, two travel reducers 1 2, two travel reducers 2 3, and two lifting reducers 4. The top side of the support base 1 is provided with an installation groove. Two travel reducers 1 2 are fixedly installed on the inner walls of the two sides of the installation groove and are arranged symmetrically. Each of the two travel reducers 1 2 is provided with two output shafts 1 21 extending to the outside of the support base 1. The travel reducer 2 3 is fixedly installed on the bottom inner wall of the installation groove and is provided with two output shafts 2 32 arranged symmetrically. Two lifting reducers 4 are fixedly installed on the inner walls of the front and rear sides of the installation groove. Each of the two lifting reducers 4 is provided with two output shafts 3 41 extending to the outside of the support base 1. The output shafts 1 21 and 2 32 are used to connect the wheels that support the device to move in the Y direction and in the X direction. The linkage component 1 is set on two travel reducers 2. The linkage component 1 includes two coupling slots 23 respectively set on the corresponding side of the travel reducers 2 and can transmit power through the coupling. This enables power transmission between the two travel reducers 2, so that the motor installed on the motor mounting base 22 can simultaneously provide driving force to the two travel reducers 2, thereby facilitating the control of the device to move along the Y direction by the wheel installed on the output shaft 21. The linkage component 2 is set on the two lifting reducers 4. The linkage component 2 includes two coupling clamps 42 that are rotatably mounted on the corresponding lifting reducers 4 and can be connected by a coupling for transmission. It can realize the power transmission between the two lifting reducers 4, so that when the motor mounted on the motor mounting base 3 43 is working, it can realize the synchronous drive of the two lifting reducers 4.

[0021] In this embodiment, a motor mounting base 22 is fixedly installed on one of the two travel reducers 2, which is used to install a motor that provides driving force when controlling the device to move in the Y direction. A motor mounting base 31 is fixedly installed on the travel reducer 3, which is used to install a motor that provides driving force when controlling the device to move in the X direction. A motor mounting base 43 is fixedly installed on one of the two lifting reducers 4, which is used to install a motor that provides driving force when controlling the device to lift. This facilitates the installation of the drives on the travel reducers 2, travel reducers 3, and lifting reducers 4.

[0022] In this embodiment, the output shaft 3 41 and the lifting reducer 4 are provided with the same eccentric wheel structure. The two lifting reducers 4 are connected by a coupling and driven by a motor installed on the motor mounting base 3 43. At the same time, the power is transmitted to the output shaft 3 41 through the internal gear structure of the lifting reducer 4, thereby driving the eccentric wheel device installed on the output shaft 3 41 to perform pendulum motion within a 90° range, thereby lifting the heavy objects or flat platforms above it to rise and fall.

[0023] In this embodiment, in order to provide shielding protection for the wheels after they are installed on the output shaft 21, and to prevent the wheels from hitting obstacles head-on during the movement of the device, two blocks are fixedly installed on both sides of the support base 1.

[0024] In this embodiment, in order to reduce the cumbersome operation of maintenance and achieve the effect of lifelong maintenance-free operation, the walking reducer 1 2, walking reducer 2 3 and lifting reducer 4 are filled with grease and equipped with seals.

[0025] It is worth noting that after the wheels are installed on the output shaft 21 and output shaft 32 of the device, the support base 1 is rotated 180° so that multiple wheels touch the ground. The mounting slot on the support base 1 is fixed by means of baffles or sealing plates and screws, so as to achieve the closure of the mounting slot.

[0026] Working principle: In use, firstly, the drive motor is installed on motor mounting base 1 (22), motor mounting base 2 (31), and motor mounting base 3 (43). Then, the wheels are installed on output shaft 1 (21) and output shaft 2 (32) respectively, and connected to the two coupling slots 23 using couplings to achieve power transmission connection between the two travel reducers 1 (2). Using compatible couplings, the two coupling clamps 42 are connected to achieve power transmission connection between the two lifting reducers 4. Then, the drive motor installed on motor mounting base 1 (22) is started. This drive motor... The traveling reducer 2, in conjunction with the couplings in the two coupling slots 23, controls the device's movement along the Y direction. When the drive motor mounted on the motor mounting base 31 is started, it controls the device's movement along the X direction in conjunction with the traveling reducer 3. When the drive motor mounted on the motor mounting base 43 is started, it drives the eccentric wheel structure to control the output shaft 41 and the wheels mounted on it, achieving a pendulum motion. This allows for lifting heavy objects or platforms to complete lifting operations. This design not only enhances lifting capacity but also adapts to the needs of various complex working conditions. In addition, the blocks on both sides of the support base 1 effectively protect the wheels and prevent them from colliding head-on with obstacles during movement, further improving the safety performance and service life of the equipment. The entire device adopts an integrated design. The internal gear structure of the travel reducer 1 2, travel reducer 2 3 and lifting reducer 4 is compact and the transmission is smooth, reducing the number of exposed parts and reducing maintenance difficulty. The grease filling and sealing configuration in the travel reducer 1 2, travel reducer 2 3 and lifting reducer 4 achieve the goal of lifetime maintenance-free operation. These features together ensure that the four-way vehicle reducer has the advantages of high efficiency, reliability and durability in practical applications.
