Description

Technical Field

[0001] This invention relates to the field of equipment transportation technology, and specifically to a factory transfer device. Background Technology

[0002] Various types of transport vehicles, especially box trucks, have been designed to facilitate the transportation of goods for factories and logistics companies. To further improve transportation efficiency and shorten loading and unloading time, the cargo box can be detached from the chassis and replaced with a new box, or the truck can be reloaded without the box. However, the cargo box is generally large and heavy when loaded. Traditional loading and unloading processes typically use lifting equipment, but this only allows for limited transport distances. If goods are piled near the lifting equipment, they easily become full; if piled elsewhere, the cargo box needs to be moved again, which is inconvenient when using lifting equipment or forklifts. Therefore, our company previously designed and applied for a patent to solve the problem of inconvenient cargo box transport; the patent application number is 20242263156. Patent 51, entitled "A Demountable Cargo Transfer Device," describes a technical solution that facilitates the transfer of cargo compartments safely and reliably, but still requires the assistance of a forklift. Therefore, our company has designed a cargo compartment transfer device that eliminates the need for additional auxiliary equipment. Furthermore, we have designed an automatic alignment structure for the demountable cargo compartment, similar to patent CN202320471841.5, entitled "A Quick Detachment and Positioning Fixing Device for Demountable Vehicles." Therefore, our newly designed cargo compartment transfer device, which eliminates the need for additional auxiliary equipment, is designed to better adapt to the cargo compartment with its automatic alignment structure. This allows the cargo compartment to automatically align and fall onto the transfer device, eliminating the need for lifting equipment. Summary of the Invention

[0035] There are two installation methods for the angle sensor 11, and the model of the angle sensor 11 can be selected as JLUWB-X5-AOA-N.

[0036] The first type: The angle sensor 11 can be directly mounted on the first pulley 1103, or it can be indirectly connected. A second pulley 1105 is concentrically mounted on the connecting shaft 501. The second pulley 1105 only needs to be concentric with the connecting shaft 501. The second pulley 1105 has a hole in its center, the diameter of which is adapted to the diameter of the connecting shaft 501, so that the second pulley 1105 can be sleeved on the connecting shaft 501. If the hole diameter is larger than the diameter of the connecting shaft 501, the second pulley 1105 can be fixed to the crossbar 5. The second pulley 1105 is fixedly connected to the connecting shaft 501 or the crossbar 5. One end of the bracket 2 is provided with a first pulley 1103 with the same groove diameter as the second pulley 1105. An angle sensor 11 that rotates with the first pulley 1103 is provided on the first pulley 1103. A rope, belt, or chain 1101 with closed ends is fixedly sleeved on the outside of the first pulley 1103 and the second pulley 1105. There is at least one first pulley 1103. The rope, belt, or chain 1101 passes around the outside of the second pulley 1105 and the first pulley 1103. When there are two or more first pulleys 1103, the rope, belt, or chain 1101 passes directly or indirectly around the second pulley 1105. The first pulley 1103 and the second pulley 1105 are set synchronously, so that the first pulley 1103 is synchronized with the turning angle of the crossbar. The first pulley 1103 can act as a tensioning pulley. The use of a tensioning pulley is existing technology, and it can rotate relative to the rope.

[0037] The indirect contact scheme between the first pulley 1103 and the angle sensor is as follows: A first fixing plate 1102 is fixedly installed at the front end of the bracket 2. The first fixing plate 1102 is rotatably connected to a vertical first drive shaft 1104. A horizontal first pulley 1103 is fixedly sleeved on the first drive shaft 1104. A horizontal second sliding plate 1105 is fixedly sleeved on the connecting shaft 501. A rope, belt, or chain 1101 with closed ends is fixedly sleeved on the outside of the first pulley 1103 and the second pulley 1105. The rope, belt, or chain 1101 is wrapped around the first pulley 1103 and the second pulley 1105 at least once. An angle sensor 11 that rotates with it is fixedly installed on the first drive shaft 1104.

[0038] The second type: The front end of the bracket 2 is provided with a third transmission rod 1202 parallel to the crossbar 5. The third transmission rod 1202 is rotatably connected to the crossbar 5 through the first transmission rod 1203 and the second transmission rod 1204. The angle sensor 11 is indirectly or directly fixed on the third transmission rod 1202.

[0039] The angle sensor 11 can be directly mounted on the third transmission rod 1202, or it can be indirectly connected. Indirect solution: A fixing sleeve 12 is vertically fixedly installed at the front end of the bracket 2. A second drive shaft 1201 is rotatably inserted inside the fixing sleeve 12. A third drive rod 1202, parallel to the crossbar 5, is fixedly connected to the bottom of the second drive shaft 1201. The third drive rod 1202 and the crossbar 5 are located on the same horizontal plane. A first drive rod 1203 and a second drive rod 1204, which are parallel to each other, are arranged between the crossbar 5 and the third drive rod 1202. The first drive rod 1203 and the second drive rod 1204 are arranged longitudinally and at intervals. One end of the second transmission rod 1204 is hinged to the crossbar 5, and the other end is hinged to the third transmission rod 1202; this causes the first transmission rod 1203 and the second transmission rod 1204 to rotate horizontally relative to the crossbar 5 and the third transmission rod; an angle sensor 11 is fixedly installed on the top of the second transmission shaft 1201; when the crossbar 5 rotates, it drives the first transmission rod 1203 and the second transmission rod 1204, which in turn drives the third transmission rod 1202 to rotate with it, and the third transmission rod 1202 drives the second transmission shaft 1201 to rotate with it, which in turn drives the angle sensor 11 to rotate.

[0040] The bracket 2 is located on the front or rear side of the steering plate and is equipped with a rotating abutment structure that allows the crossbar 5 to rotate no more than ninety degrees.

[0041] There are two types of rotating abutment structures: The first type is: the bracket 2 is fixedly installed with a second fixing plate 1501 in the middle of the front or rear side of the steering plate. The second fixing plate 1501 is used to rotate with the crossbar 5 or the support rod 1002 to abut the stop bar 15. When the crossbar 5 or the support rod 1002 rotates ninety degrees, the stop bar 15 on the crossbar 5 or the support rod 1002 abuts against the second fixing plate 1501 on the steering plate, so that the left and right steering positioning can be achieved as required.

[0042] The second type involves a bracket 2 with a first baffle 14 fixedly installed at the center of the front or rear side of the steering plate. A first abutment plate 1401 is fixedly installed on the crossbar 5, capable of abutting against the first baffle 14 and causing the crossbar 5 to rotate no more than 90 degrees clockwise. There are two first baffles 14, located on opposite sides of the steering plate. The two first baffles 14 are positioned along the rotation trajectory of the first abutment plate 1401. This allows for left and right steering positioning as needed.

[0043] Bracket 2 itself has two types of construction: The first type: The bracket 2 includes a first bracket 201 and a second bracket 202, the first bracket 201 and the second bracket 202 are slidably arranged relative to each other, so that the bracket 2 can extend and retract longitudinally.

[0044] The second type: the bracket 2 has at least one break, at which a front bracket and a rear bracket are formed. The break is provided with an up-and-down rotating structure that allows the two broken brackets to rotate and connect. The up-and-down rotating structure includes a pin 204 that is laterally connected to one of the front and rear brackets, and a connecting plate 203 that is rotatably connected to the pin is fixedly connected to the other side.

[0045] The bracket 2 is laterally connected to the left and right ends respectively; the distance from the auxiliary wheel 7 to the longitudinal center line of the bracket 2 is greater than the rotation radius of the wheel assembly 4; the bracket 2 can be directly connected to the auxiliary wheel 7 or it can be connected by setting a connecting frame; Several sets of auxiliary wheels 7 are arranged at longitudinal intervals. The auxiliary wheels 7 can be powered or unpowered, and can be swivel wheels or fixed wheels. Several sets of connecting frames are also arranged at longitudinal intervals. Each connecting frame specifically includes two ends that are respectively connected to the left and right sides of the bracket 2. The auxiliary wheels 7 are fixed to both ends of the connecting frame, which are located on the left and right sides of the bracket 2. The transverse length of the connecting frame is generally greater than or equal to the farthest transverse distance of the wheel assembly 4. The auxiliary wheels 7 are provided to maintain balance when the crossbar turns to a 90-degree angle. The auxiliary wheels 7 can be powered or unpowered, and can be swivel wheels or fixed wheels. Powered wheels are those with a motor, unpowered wheels are those without a motor, and swivel and fixed wheels are common knowledge.

[0046] A longitudinal shaft 404 is fixedly installed on the crossbar 5. A sleeve 405 is rotatably connected to the longitudinal shaft 404. The sleeve 405 is fixedly connected to the balance frame 406 arranged in the longitudinal direction. A set of wheel assemblies 4 is fixedly installed at the front end of the balance frame 406, and a wheel assembly 4 or balance wheel 407 is fixedly installed at the rear end.
