Description

Technical Field

[0001] The present invention relates to the field of four-way vehicles, and particularly to a double-rack stable height-adjustable four-way vehicle. Background Art

[0002] A four-way vehicle is a handling device in the field of warehousing logistics. It moves on the frame of warehousing logistics and transports the materials thereon to a designated position.

[0003] Active wheels and driven wheels are provided on both the movable frame and the fixed frame of the four-way vehicle. The movable frame and the fixed frame alternately contact the frame of the warehouse. The active wheels and driven wheels on the movable frame and the active wheels and driven wheels on the fixed frame work alternately. Currently, commonly used four-way vehicles usually use an oil cylinder to push the movable frame and the active wheels and driven wheels thereon close to and away from the frame of the warehouse. During the use of the oil cylinder, a large amount of oil will leak out and fall onto the frame of the warehouse, making the frame of the warehouse too smooth, resulting in the four-way vehicle being unable to start and stop normally and reducing the handling accuracy of the four-way vehicle. During the use process, a chain assembly is used to transmit kinetic energy. In this process, the power component directly uses a chain to connect with the sprocket at the end of the connecting shaft. During the use process, the power component often rotates forward and backward, and the chain often needs to be tensioned during the use process. Summary of the Invention

[0004] The purpose of the present invention is to provide a double-rack stable height-adjustable four-way vehicle to solve the above problems.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A double-rack stable height-adjustable four-way vehicle includes a fixed frame, a movable frame, a transmission member, and a driven part. The fixed frame and the movable frame are snap-connected. A sliding member is provided on the fixed frame. A sliding groove and a material placing surface are provided on the movable frame. The transmission member is connected to the fixed frame through a power component. The transmission member is connected to the wheels on the first connecting shaft and the second connecting shaft through a conveyor belt. Both the first connecting shaft and the second connecting shaft are connected to the active wheels on the fixed frame and the movable frame respectively through a gear assembly. The driven part is connected to the fixed frame through a driving component and is movably connected to the movable frame through a driven groove on the movable frame.

[0007] Further, the sliding member is movably connected to the movable frame through the sliding groove, and there are multiple sliding members and sliding grooves.

[0008] Further, both ends of the first connecting shaft and the second connecting shaft are connected to the gear assembly, and a universal joint is provided near the gear assembly on the second connecting shaft.

[0009] Further, the driven part includes a gear-rack assembly, a third connecting shaft, and a driving wheel. The gear-rack assembly is connected to both ends of the third connecting shaft through the driving wheel.

[0010] Further, two racks are provided on the gear-rack assembly. One of the gear-rack assemblies is connected to the rotating shaft of the driving member, and the driving wheel on the third connecting shaft meshes with the rack of the gear-rack assembly.

[0011] Further, the two racks on the gear-rack assembly are located on the upper and lower sides of the gear thereon, and both racks on the gear-rack assembly mesh with the gear on the gear-rack assembly. An adjusting member is provided at the end of the third connecting shaft.

[0012] Further, an insertion wheel is provided on the adjusting member away from the third connecting shaft, and the insertion wheel is specifically located in the driven slot of the driven block on the movable frame.

[0013] The beneficial effects of the present invention are as follows: A double-rack stable height-adjustable four-way vehicle is provided. By the mutual cooperation of the fixed frame, the movable frame, the transmission member and the driven part, a motor is used to replace the oil cylinder to push the movable frame and the driving wheel and the driven wheel thereon to move up and down. During this process, a universal joint is added to the connecting shaft, and at the same time, a sprocket assembly is used as the power member to drive the gear assemblies at both ends of the connecting shaft to rotate, thereby driving the driving wheel and the driven wheel to rotate. The driving member drives the movable frame to move up and down through the double-gear assembly and the connecting shaft, achieving the effect of not needing to regularly tension the chain, improving the accuracy of the four-way vehicle and reducing the maintenance cost of the four-way vehicle.

A sliding groove 21 and a feeding surface 22 are arranged on the movable frame 2. The transmission part 4 is connected to the fixed frame 1 through a power part 3. The transmission part 4 is connected to the wheels on the first connecting shaft 5 and the second connecting shaft 6 through a conveyor belt to drive the rotation of the two. Both the first connecting shaft 5 and the second connecting shaft 6 are respectively connected to the driving wheels 12 on the fixed frame 1 and the movable frame 2 through a gear assembly 7 to provide power for the movement of the driving wheels 12 on the fixed frame 1 and the movable frame 2. The driven part 9 is connected to the fixed frame 1 through a driving part 8. The driven part 9 is movably connected to the movable frame 2 through a driven groove 11 on the movable frame 2 to drive the movable frame 2 to move, so that the driving wheels 12 and the driven wheels 13 thereon contact and approach the frame of the warehouse. Both the power part 3 and the driving part 8 are electrically connected to the internal control system.

[0024] The sliding part 101 is movably connected to the movable frame 2 through the sliding groove 21. There are multiple sliding parts 101 and sliding grooves 21 to ensure good stability when the fixed frame 1 and the movable frame 2 move relatively.

[0025] Both ends of the first connecting shaft 5 and the second connecting shaft 6 are connected to the gear assembly 7 to ensure uniform force on the first connecting shaft 5 and the second connecting shaft 6. A universal joint 61 is arranged on the second connecting shaft 6 near the gear assembly 7 to smoothly transmit kinetic energy.

[0026] The driven part 9 includes a gear-rack assembly 91, a third connecting shaft 92, and a driving wheel 93. The gear-rack assembly 91 is connected to the two ends of the third connecting shaft 92 through the driving wheel 93 to ensure uniform force on the third connecting shaft 92.

[0027] Two racks are provided on the gear-rack assembly 91 for stable transmission of kinetic energy. One of the gear-rack assemblies 91 is connected to the rotating shaft of the driving member 8, and the driving wheel 93 on the third connecting shaft 92 meshes with the rack of the gear-rack assembly 91.

[0028] The two racks on the gear-rack assembly 91 are located on the upper and lower sides of the gear thereon, and both racks on the gear-rack assembly 91 mesh with the gear on the gear-rack assembly 91 for stable transmission of kinetic energy. An adjusting member 94 is provided at the end of the third connecting shaft 92 for driving the movable frame 2 to move.

[0030] The working principle of the present invention is as follows: Before starting to use the four-way vehicle, place the four-way vehicle on the frame of the warehouse, and the external handling mechanism transports the materials to be handled to the feeding surface of the movable frame; When the driving wheels and driven wheels on the movable frame are required to work: Under the control of the internal control system, the power component works, drives the first connecting shaft and the second connecting shaft to rotate through the transmission component, and the first connecting shaft and the second connecting shaft drive the driving wheels on the fixed frame and the movable frame to work through the gear assembly. During this process, only the driving wheels and driven wheels on the movable frame are in contact with the warehouse frame, thereby driving the entire four-way vehicle to move on the warehouse frame, and the driven wheels rotate accordingly during this process; When the driving wheels and driven wheels on the fixed frame are required to work: Under the control of the internal control system, the driving component works to drive the gear-rack assembly 91 to work, and then drives the third connecting shaft to rotate. During this process, the third connecting shaft drives the adjusting component on it to rotate, and then the insertion wheel on the adjusting component slides in the driven slot on the driven block, driving the movable frame to rise so that the driving wheels and driven wheels on the movable frame are separated from the warehouse frame. Then, under the control of the internal control system, the power component starts to work, drives the first connecting shaft and the second connecting shaft to rotate through the transmission component, and further drives the gear assembly on it to work. During this process, the gear assembly drives the driving wheels on the fixed frame and the movable frame to work. During this process, only the driving wheels and driven wheels on the fixed frame are in contact with the warehouse frame, thereby driving the entire four-way vehicle to move on the warehouse frame, and the driven wheels rotate accordingly during this process; When the driving wheels and driven wheels on the movable frame are required to work again: Under the control of the internal control system, the driving component works to drive the movable frame to reset, so that the driving wheels and driven wheels on the movable frame are in contact with the warehouse frame, and at the same time, the driving wheels and driven wheels on the fixed frame are separated from the warehouse frame; Keep the above process until the work is completed.

[0031] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be understood to be within the protection scope of the present invention.
