Description

Technical Field

[0001] This utility model generally relates to the field of logistics technology, and more specifically, to a transfer device and conveying equipment. Background Technology

[0002] Air logistics systems typically handle containerized equipment used to consolidate cargo for easier transport and handling. Containerized equipment generally falls into two main categories: ULD (Upper Limit Container) containers and pallets. Depending on the aircraft model and cabin size and capacity, there are various types of containerized equipment, ranging in length and width from approximately 1m to 3m (e.g., widths of 1.53m or 2.44m are available), with rated load capacities ranging from 2 to 6.8 tons. Due to the varying dimensions of different containerized equipment, different types require individual or multiple transport trips. Since the volume transported per trip is relatively fixed, this results in numerous round trips, impacting transport efficiency. Furthermore, after the transfer unit moves the containerized equipment to the designated location, it needs to be docked and transferred to a conveyor. Since these conveyors are generally non-powered, operators must manually unload the containerized equipment and move it onto the conveyor, resulting in high labor intensity and low transfer efficiency.

[0077] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0078] This embodiment provides a transfer device, such as... Figures 1-2 As shown, the transfer device includes a traveling frame mechanism 1 and a loading platform 2. The loading platform 2 includes a loading support 21 and multiple conveying components 22. The loading support 21 is disposed on the traveling frame mechanism 1, and the multiple conveying components 22 are disposed parallel to each other on the loading support 21. The multiple conveying components 22 are used to carry at least one item to be transported 100 and to transport the item to be transported 100 along a first direction.

[0079] Among them, the item to be transported 100 can be either cargo or container equipment capable of packaging cargo, and the size of different types of items to be transported 100 will vary.

[0080] The transfer device provided in this embodiment allows multiple conveying components 22 to carry multiple items 100 if the size of the item 100 to be transported is relatively small; if the size of the item 100 to be transported is relatively large, multiple conveying components 22 can jointly carry one item 100. By using multiple conveying components 22, at least one item 100 to be transported can be carried, ensuring that items 100 of different sizes can be transported in one go, increasing the amount of transported in a single transport, reducing the number of round trips, and improving transport efficiency.

[0081] If the conveying component 22 outputs the item to be transported 100 along the first direction, the operator still needs to manually unload the item to be transported 100 and move it to the preset position, which is labor-intensive and results in low production efficiency.

[0082] To solve this problem, such as Figure 3 As shown, the transfer device also includes a transfer mechanism 3, which is disposed on at least one side of the traveling frame mechanism 1 along the first direction. The transfer mechanism 3 is configured to receive the item 100 to be transported located on the conveying assembly 22 and output it.

[0083] For example, the number of transfer mechanisms 3 can be one, with one transfer mechanism 3 disposed on one side of the traveling frame mechanism 1 along the first direction, i.e., the transfer mechanism 3 is disposed on one side of the traveling frame mechanism 1; or the number of transfer mechanisms 3 can be two, with two transfer mechanisms 3 respectively disposed on both sides of the traveling frame mechanism 1 along the first direction, i.e., the transfer mechanisms 3 are disposed on both sides of the traveling frame mechanism 1. Specifically, two transfer mechanisms 3 are used to realize the same-direction or opposite-direction transmission of multiple small transport items 100, or the transmission process of a large transport item 100 is realized by controlling the combined power of the two transfer mechanisms 3.

[0084] The transfer device provided in this embodiment utilizes the transfer mechanism 3 to receive the item to be transported 100 located on the conveying component 22, thereby realizing the extraction function, and thus realizing the docking and power transmission process with the preset position. The transfer mechanism 3 is correspondingly set with multiple conveying components 22, and the transfer mechanism 3 can adapt to various specifications of the item to be transported 100. According to the size of the item to be transported 100, the transfer mechanism 3 can transfer at least one item to be transported 100 to the preset position.

[0085] The following is a detailed introduction to the traveling chassis mechanism 1, the cargo platform 2, and the transfer mechanism 3.

[0086] like Figure 4As shown, the traveling chassis mechanism 1 includes a chassis support 11, which is a frame structure. The loading platform 2 and the transfer mechanism 3 are set on the chassis support 11. The width direction of the chassis support 11 is the first direction, which is identified by D1. The height direction of the chassis support 11 is the second direction, which is identified by D2. The length direction of the chassis support 11 is the third direction, which is identified by D3. The first direction, the second direction and the third direction are perpendicular to each other.

[0087] The base frame 11 includes a support frame 111 and a wheel box frame 112. The support frame 111 is welded from steel structural profiles and provides installation space for the loading platform 2 and the transfer mechanism 3, as well as providing a certain supporting force. The wheel box frame 112 is disposed at the end of the support frame 111. Exemplarily, the wheel box frame 112 is welded to at least one end of the support frame 111 along a third direction.

[0088] In one embodiment, such as Figures 4-5 As shown, the traveling frame mechanism 1 also includes a traveling wheel assembly 12, which is disposed within the wheel box frame 112 of the frame support 11 and is used to drive the frame support 11 to travel. The traveling wheel assembly 12 includes a traveling drive source 121, a first bearing 122, and traveling wheels 123. The traveling drive source 121 can be a traveling motor. The traveling drive source 121 is disposed on the frame support 11, and its output shaft is connected to the traveling wheels 123, driving the traveling wheels 123 to rotate. The first bearing 122 is sleeved outside the output shaft of the traveling drive source 121 and positioned between the output shaft and the frame support 11, improving the smoothness of the rotation of the output shaft of the traveling drive source 121.

[0089] For example, there are multiple walking wheel assemblies 12, which are located on both sides of the base frame 11 along a third direction to ensure the stability and balance of the walking movement. This embodiment takes two walking wheel assemblies 12 as an example and uses a dual-motor drive to achieve the horizontal movement of the whole machine.

[0090] If the length of the base frame bracket 11 along the third direction is relatively large, installation deviations will occur when the traveling wheel assemblies 12 located on both sides of the base frame bracket 11 along the third direction are installed. Therefore, as follows: Figures 6-7As shown, the base frame 11 is provided with mounting reference surfaces 1121 distributed along a third direction, and multiple traveling wheel assemblies 12 are mounted on the mounting reference surfaces 1121. A large gantry milling machine is used to machine the plane in the wheel box frame 112 used for mounting the traveling wheel assemblies 12 to form the mounting reference surfaces 1121, ensuring that the mounting reference surfaces 1121 are coplanar. Multiple traveling wheel assemblies 12 are mounted on the mounting reference surfaces 1121 or with the mounting reference surfaces 1121 as the mounting reference, ensuring that the multiple traveling wheel assemblies 12 are installed without skew or angles, ensuring stable and reliable travel operation.

[0091] In one embodiment, such as Figure 8 As shown, the walking frame mechanism 1 also includes a guide wheel assembly 13. The guide wheel assembly 13 includes a guide seat 131 and a guide wheel 132. The guide seat 131 is disposed on the frame support 11, and the guide wheel 132 is rotatably connected to the guide seat 131. The guide wheel 132 plays an auxiliary guiding role during the walking process.

[0092] For example, the guide seat 131 and the base bracket 11 can be directly connected by welding, or they can be detachably connected by bolts, or the guide seat 131 and the base bracket 11 can be connected in other ways.

[0093] In one embodiment, the guide wheel assembly 13 further includes a guide shaft 133 and a second bearing 134. The guide wheel 132 is rotatably connected to the guide seat 131 via the guide shaft 133. The guide shaft 133 passes through the second bearing 134, which is located between the guide shaft 133 and the guide seat 131 to ensure smooth rotation.

[0094] If the guide seat 131 and the base bracket 11 are only connected by bolts, the bolts will break due to direct shear force when the guide wheel 132 is subjected to lateral impact. To solve this problem, such as Figures 9-11 As shown, one of the base bracket 11 and the guide seat 131 is provided with a boss 1311, and the other is provided with a groove 110 corresponding to the boss 1311. The boss 1311 abuts against the groove wall of the groove 110. For example, the support frame 111 of the base bracket 11 is provided with a groove 110, and the guide seat 131 is provided with a boss 1311.

[0095] With this configuration, the base frame support 11 and the guide seat 131 are interlocked by the boss 1311 and the groove 110, ensuring that the lateral impact force on the guide wheel 132 is directly applied to the base frame support 11. As a steel structure, the base frame support 11 has a relatively high structural strength and can withstand a large lateral impact force, avoiding the situation where the bolts are directly subjected to impact shear force and thus breakage, ensuring the reliability of the travel guide.

[0096] In one embodiment, such as Figure 12As shown, the transfer device also includes a support mechanism 4 and a lifting mechanism 5. The support mechanism 4 is disposed on the traveling frame mechanism 1, and the lifting mechanism 5 is at least partially disposed on the support mechanism 4. The output end of the lifting mechanism 5 is connected to the loading platform 2. The lifting mechanism 5 can drive the loading platform 2 to rise and fall in the second direction, thereby increasing the spatial transport range of the item to be transported 100.

[0097] Specifically, the support mechanism 4 includes a crossbeam 42 and a column 41. The column 41 is set on the traveling base frame mechanism 1 and extends along the second direction. The column 41 can be made of steel structural profiles and is the main part supporting the entire structure. There are two columns 41, which are arranged in parallel and spaced apart. The crossbeam 42 is set between the two columns 41 to form a portal structure. At this time, the crossbeam 42, the column 41 and the base frame support 11 form an integral structure to ensure installation stability.

[0098] Specifically, the lifting mechanism 5 includes a fixed pulley 51 and a movable pulley 52 (such as...). Figure 2 As shown in the diagram, a fixed pulley 51 is rotatably connected to a crossbeam 42 and / or a column 41. For example, the fixed pulley 51 is provided on the crossbeam 42, which provides an installation position for the fixed pulley 51. A movable pulley 52 is rotatably connected to the cargo support 21. A traction rope is wound around the fixed pulley 51 and the movable pulley 52 respectively. The movable pulley 52 is the main power component for realizing the lifting transmission. By stretching the traction rope, the movable pulley 52 is pulled and the cargo support 21 is driven to move up and down, thereby realizing the lifting process of the cargo platform 2.

[0099] It is understood that in some other embodiments, the lifting mechanism 5 may also be selected from linear lifting drive methods such as lifting cylinders or hydraulic cylinders.

[0100] In one embodiment, one of the cargo support 21 and the column 41 is provided with a guide wheel 211, and the other is provided with a guide rail 411. The guide rail 411 extends along a second direction, and the guide wheel 211 and the guide rail 411 are in rolling engagement. The guide rail 411 can be made of special steel rail, which has high strength and wear resistance. Through the rolling engagement of the guide rail 411 and the guide wheel 211, a certain guiding force is provided for the lifting and lowering of the cargo platform 2, ensuring the stable operation of the cargo platform 2 during lifting and lowering.

[0101] In one embodiment, the loading platform 2 includes a loading support 21 and multiple conveying components 22. The loading support 21 is mounted on the traveling frame mechanism 1 and serves as the main load-bearing structure. The conveying components 22 are mounted on the loading support 21 and can also be referred to as roller conveyors. The conveying components 22 are the power components for the transported item 100. The multiple conveying components 22 are arranged in parallel and spaced apart on the loading support 21. For example, the number of conveying components 22 is two, i.e., a double-row track platform structure is adopted.

[0102] Specifically, such as Figure 13 As shown, the conveying assembly 22 includes a conveying drive source 221 and a roller 222. The conveying drive source 221 can be a motor. The conveying drive source 221 is disposed on the cargo support 21. The output end of the conveying drive source 221 is connected to the roller 222. The conveying drive source 221 drives the roller 222 to rotate relative to the cargo support 21. The roller 222 is used to carry the item 100 to be transported.

[0103] The rollers 222 are arranged in parallel at intervals along a third direction. The conveying drive source 221 is connected to the rollers 222 through a transmission structure, so that one conveying drive source 221 can drive the multiple rollers 222 to rotate synchronously. For example, the transmission structure may be a transmission chain, belt, etc.

[0104] Specifically, the rollers 222 of the multiple conveying components 22 are used to correspondingly carry multiple items 100 to be transported. Since each conveying component 22 can be driven by a separate conveying drive source 221 to realize the transmission of the item 100 to be transported, when the conveying drive sources 221 of the multiple conveying components 22 are driven respectively, the rollers 222 corresponding to each conveying component 22 can drive the smaller items 100 to be transported to move forward / backward along the first direction for transport.

[0105] Specifically, the rollers 222 of multiple conveying components 22 are used to jointly carry a single item 100 to be transported. When the conveying drive sources 221 of multiple conveying components 22 are driven together, the rollers 222 of the multiple conveying components 22 can jointly transport a large item 100 to be transported, ensuring the synchronicity of the transport of the item 100.

[0106] In one embodiment, such as Figure 14 As shown, the transfer mechanism 3 includes a telescopic component 32 and multiple load-bearing components 31. The multiple load-bearing components 31 are correspondingly arranged with multiple conveying components 22 and are used to receive the items 100 to be transported located on the conveying components 22. The telescopic component 32 is arranged on the traveling frame mechanism 1, and the telescopic component 32 is connected to the multiple load-bearing components 31 and can drive the multiple load-bearing components 31 to move towards or away from the loading platform 2.

[0107] For example, when the item 100 to be transported on the loading platform 2 needs to be output, the telescopic component 32 drives multiple carrier components 31 to move towards the loading platform 2, so that the multiple carrier components 31 can receive the item 100 to be transported located on the conveying component 22 in the loading platform 2. Then, the telescopic component 32 drives the multiple carrier components 31 to move away from the loading platform 2, and unloads the item 100 to be transported from the multiple carrier components 31. The extraction process of multiple carrier components 31 can be realized by using a single telescopic component 32, and the telescopic component 32 only performs one action, saving production costs and improving operation efficiency.

[0108] Specifically, the bearing assembly 31 includes a rotating shaft 311, a friction wheel component 312, and a bearing drive source 313. The rotating shaft 311 is perpendicular to the first direction, and the friction wheel component 312 is disposed on the rotating shaft 311. The friction wheel component 312 can bear the item to be transported 100, increasing the friction between it and the item to be transported 100 and reducing the possibility of slippage of the item to be transported 100. The bearing drive source 313 can be a drive motor. The output end of the bearing drive source 313 is connected to the rotating shaft 311, and the bearing drive source 313 can drive the rotating shaft 311 and rotate the friction wheel component 312, enabling the friction wheel component 312 to receive or unload the item to be transported 100.

[0109] It is understandable that multiple carrier components 31 and multiple conveying components 22 are correspondingly arranged so that the carrier component 31 can correspondingly receive the item 100 to be transported on the conveying component 22. The rotation shafts 311 of the multiple carrier components 31 are coaxially arranged and not connected to each other, so as to ensure the independence of the multiple carrier components 31 in transporting the item 100. Specifically, the load-bearing drive source 313 of the multiple load-bearing components 31 drives the multiple friction wheel components 312 to rotate via the rotating shaft 311, which can transport multiple smaller items 100 to a preset position in the same direction; or the load-bearing drive source 313 of the multiple load-bearing components 31 drives the multiple friction wheel components 312 to rotate in different directions via the rotating shaft 311, that is, a portion of the multiple items 100 to be transported is transported forward along the first direction, and another portion is transported backward along the first direction; or the load-bearing drive source 313 of the multiple load-bearing components 31 simultaneously drives the multiple friction wheel components 312 to rotate via the rotating shaft 311, so as to transport a larger item 100 to a preset position, wherein the preset position can be selected from the conveyor 200 structure for the next step, such as the conveyor 200.

One end of the drive shaft 322 is connected to the cam 321, and the other end is connected to the rotation shaft 311 of the other support components 31. By using the drive shaft 322 to be connected to the rotation shaft 311 of multiple support components 31 at the same time, the problem of long span affecting transmission synchronization can be solved.

[0111] The telescopic drive source 323 can be a drive motor. The output end of the telescopic drive source 323 is connected to the cam 321. The output end of the telescopic drive source 323 and the transmission shaft 322 are not coaxially arranged. That is, the connection position between the output end of the telescopic drive source 323 and the cam 321 is different from the connection position between the cam 321 and the transmission shaft 322. The telescopic drive source 323 can drive the rotating shaft 311 and the friction wheel component 312 to rotate through the cam 321 and the transmission shaft 322, so that the friction wheel component 312 moves towards or away from the loading platform 2, thereby realizing the telescopic function of the friction wheel component 312.

[0112] In one embodiment, the telescopic component 32 further includes a first elastic element 324, wherein the first elastic element 324 may be a spring, an elastic cylinder, or other elastic or shock-absorbing components. The first elastic element 324 is located between the rotating shaft 311 and the transmission shaft 322. One end of the first elastic element 324 is connected to the cam 321, and the other end is connected to the rotating shaft 311 of one of the bearing components 31, so that the cam 321 drives the rotating shaft 311 to rotate through the first elastic element 324 to realize the telescopic function. The first elastic element 324 plays the role of intermediate connection while also playing the role of shock absorption and buffering.

[0113] In one embodiment, the telescopic component 32 further includes a second elastic element 325, wherein the second elastic element 325 may be a spring, an elastic cylinder, or other elastic or shock-absorbing components. The second elastic element 325 is located between the rotating shaft 311 and the transmission shaft 322. One end of the second elastic element 325 is connected to the transmission shaft 322, and the other end is connected to the rotating shaft 311 of the other bearing component 31, so that the transmission shaft 322 drives the rotating shaft 311 to rotate through the second elastic element 325 to realize the telescopic function. The second elastic element 325 not only serves as an intermediate connection, but also serves as a shock absorber.

[0114] This embodiment also provides a conveying device, including a conveyor 200 and the aforementioned transfer device. The conveyor 200 and the transfer device are arranged along a first direction. The transfer mechanism 3 of the transfer device can receive the item 100 to be transported located on the conveying assembly 22 and transport it to the conveyor 200.

[0115] The conveying equipment provided in this embodiment utilizes multiple conveying components 22 to carry at least one item 100 to be transported, ensuring that items 100 of different sizes can be transported in one go, increasing the conveying capacity per transport, reducing the number of round trips, and improving conveying efficiency. The transfer mechanism 3 can receive the item 100 located on the conveying component 22, realizing the extraction function, thereby achieving docking and power transmission with a preset position. The transfer mechanism 3 is correspondingly arranged with multiple conveying components 22, and can adapt to various specifications of items 100 to be transported. Based on the size of the item 100, the transfer mechanism 3 can transfer at least one item 100 to the preset position.
