Abstract
Description
Technical Field
[0001] This application relates to the field of warehousing and transshipment, and in particular to a transshipment trolley. Background Technology
[0002] In the warehousing and logistics sector, spare parts transfer trolleys are crucial tools for ensuring the efficient flow of spare parts. Traditional trolleys generally use fixed-size carrying platforms, which have significant limitations in practical applications: when handling large or irregularly shaped spare parts, the fixed platform's insufficient area causes the spare parts to sag or become unstable, increasing the risk of tipping over; while when transferring a large number of small spare parts, the limited platform area necessitates multiple back-and-forth trips, severely hindering operational efficiency. Especially for easily rolling cylindrical spare parts, fixed trolleys lack effective lateral protection structures, making spare parts prone to scattering during transportation, causing damage to parts and creating safety hazards. Although existing technologies attempt to expand functionality through detachable railings, the disassembly and assembly process is cumbersome, and the additional components pose a risk of loss during storage. Utility Model Content
[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a transfer cart.
[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0005] This application provides:
[0006] A transfer trolley having a first direction and a second direction intersecting each other, comprising:
[0007] A base plate, wherein rollers are provided on the bottom surface of the base plate;
[0008] Two baffles are respectively disposed on both sides of the base plate along the first direction and abut against each other. The base plate and the two baffles surround to form a receiving groove. Sliding plates are slidably disposed in the side walls extending along the first direction at both ends of the baffles. A first linear drive assembly is also disposed on the side walls extending along the first direction at both ends of the baffles. The first linear drive assembly is used to drive the sliding plates to move.
[0009] Furthermore, the transfer trolley also includes a second direction, the baffle includes a first plate and a second plate, both ends of the first plate are provided with second plates extending along the first direction, the two second plates on the same side along the second direction are abutted together, the sliding plate is slidably disposed on the second plate, the first linear drive assembly is disposed on the second plate, and the first linear drive assembly is used to drive the sliding plate to move.
[0010] Furthermore, the shield is U-shaped.
[0011] Furthermore, the transfer trolley also includes a third direction intersecting the first direction. The base plate has grooves on both sides along the first direction, and the grooves have first slots along the sidewalls of the third direction. The first plate has a first sliding groove, and a snap-fit plate is slidably disposed in the first sliding groove. The first plate is also provided with a second linear drive assembly, which is connected to the snap-fit plate. The second linear drive assembly is used to drive the snap-fit plate to slide along the first sliding groove to the first slot.
[0012] Furthermore, a second slot is formed on the side wall of the groove along the first direction.
[0013] Furthermore, a second groove is provided in the second plate, and the sliding plate is slidably disposed in the second groove;
[0014] The first linear drive assembly includes a first rotating shaft and a first lead screw. The first rotating shaft is rotatably mounted on the second plate, and the first lead screw is disposed in the second slide groove. The first lead screw is connected to the sliding plate in a transmission manner, and a first drive member is disposed at the end of the first rotating shaft opposite to the first lead screw.
[0015] Furthermore, the snap-fit plate includes a transmission part that is slidably disposed in the first groove, and the end of the transmission part is provided with a snap-fit part.
[0016] Furthermore, the second linear drive assembly includes a second rotating shaft rotatably mounted on the first plate, a second lead screw is provided at the end of the second rotating shaft facing the snap-fit plate, and a second drive member is provided at the end of the second rotating shaft away from the second lead screw.

[0019] This application achieves the transfer function through rollers set on the bottom surface of the base plate. Two baffles are set on both sides of the base plate along the first direction and abut against each other, so that the base plate and the baffles form a receiving groove that can prevent spare parts from falling. By sliding plates set in the side wall of the baffles and the first linear drive assembly that drives their movement, the sliding plates can be extended and adjusted, so that the loading area of the receiving groove can accommodate spare parts of different sizes. This avoids the risk of large spare parts being suspended and tipped over due to insufficient platform. At the same time, the baffles and the sliding plates form a continuous side wall, which effectively prevents cylindrical spare parts from rolling and falling.

[0033] This application provides a transfer trolley having intersecting first direction X, second direction Y, and third direction Z. It includes a base plate 100 and two baffles 200. Specifically, the bottom surface of the base plate 100 is provided with rollers 110. The two baffles 200 are respectively disposed on both sides of the base plate 100 along the first direction X and abut against each other. The base plate 100 and the two baffles 200 surround to form a receiving groove 101. Sliding plates 221 are slidably disposed in the side walls extending along the first direction X at both ends of the baffles 200. A first linear drive assembly 300 is also disposed on the side walls extending along the first direction X at both ends of the baffles 200. The first linear drive assembly 300 is used to drive the sliding plates 221 to move.
[0034] In this embodiment, the first direction X is the horizontal direction, the second direction Y is the vertical direction, and the third direction Z is the vertical direction.
[0035] In this embodiment, the shielding plate 200 is U-shaped, and the two U-shaped shielding plates 200 abut against each other and cooperate with the base plate 100 to form a closed receiving groove 101.
[0036] Please see Figure 1 and Figure 2 As shown, in the initial state, the baffles 200 on both sides of the base plate 100 abut against each other to form a receiving groove 101. At this time, the receiving groove 101 is blocked by the baffles 200. If a small or easily rolling cylindrical spare part is placed in the receiving groove 101, the spare part will not fall and cause a safety hazard because it is protected by the baffles 200 around it.
[0037] Furthermore, when it is necessary to store larger spare parts, the two baffles 200 can be rotated 90 degrees away from each other. At this time, the baffles 200 are set horizontally, and the sliding plate 221 in the side wall extending along the first direction X is also set horizontally. At this time, the first linear drive assembly 300 drives the sliding plate 221 to move along the first direction X. For this purpose, two adjacent sliding plates 221 on the same side of the second direction Y path move closer to each other and abut against each other, thereby forming the receiving groove 101 again. The receiving groove 101 in this state has a larger area than the receiving groove 101 in the initial state, so it can accommodate larger spare parts, and the spare parts can also be blocked by the dam formed by the baffles 200 and the sliding plate 221.
[0038] Compared with existing trolleys, this application increases the area of the receiving slot 101 by flipping the cover plate 200 and driving the sliding plate 221 to slide via the first linear drive assembly 300, thereby enabling the pushing and transferring of spare parts of different sizes. When small spare parts need to be transferred, the cover plate 200 can be in its initial vertical state to accommodate smaller spare parts such as cylinders. When larger spare parts need to be transferred, the cover plate 200 is simply flipped to a horizontal state, and then the sliding plate 221 is moved by the first linear drive assembly 300, thereby increasing the area of the receiving slot 101 and enabling the pushing and transferring of larger spare parts.
[0039] For example, in order to enable the entire trolley to move, multiple rollers 110 are provided on the bottom surface of the base plate 100. The number of rollers 110 is N, which satisfies N≥3. That is, when there are three rollers 110, the three rollers 110 form a stable triangle to support the base plate 100. In this embodiment, the base plate 100 is rectangular, and there are four rollers 110 respectively located at the four corners of the bottom surface of the base plate 100. For example, the rollers 110 are omnidirectional wheels.
[0040] In some embodiments, the transfer trolley further includes a second direction Y, the baffle 200 includes a first plate 210 and a second plate 220, both ends of the first plate 210 are provided with second plates 220 extending along the first direction X, the two second plates 220 on the same side along the second direction Y are abutted between each other, the sliding plate 221 is slidably disposed on the second plate 220, and the first linear drive assembly 300 is disposed on the second plate 220, the first linear drive assembly 300 is used to drive the sliding plate 221 to move.
[0041] Please see Figure 1 , Figure 2 as well as Figure 4 As shown, in the initial state, the sliding plate 221 is in a vertical state in the second slide groove 202. After the second plate 220 rotates 90 degrees with the first plate 210, the sliding plate 221 also rotates 90 degrees. At this time, the first linear drive assembly 300 of each second plate 220 drives the sliding plate 221 inside to slide along the second slide groove 202, so that the two adjacent sliding plates 221 on the same side move closer to each other and abut against each other. The extended sliding plate 221, together with the first plate 210 and the second plate 220, forms a dam to circumferentially block the spare parts located in the receiving groove 101 and prevent the spare parts from falling.
[0042] In some embodiments, the base plate 100 has grooves 102 on both sides along the first direction X, and the grooves 102 have first slots 1021 on the sidewalls along the third direction Z. The first plate 210 has a first sliding groove 201, and a snap-fit plate 211 is slidably disposed in the first sliding groove 201. The first plate 210 is also provided with a second linear drive assembly 400, which is connected to the snap-fit plate 211 in a transmission manner. The second linear drive assembly 400 is used to drive the snap-fit plate 211 to slide along the first sliding groove 201 to the first slot 1021.
[0043] Please see Figure 2 , Figure 3 as well as Figure 4 As shown, in the initial state, since the first plate 210 and the second plate 220 are not blocked by external forces, they are likely to flip over if subjected to external forces and thus fail to block the spare parts in the receiving slot 101. Grooves 102 are provided on both the left and right sides of the base plate 100, and a first slot 1021 is provided on the bottom surface of the groove 102. In order to prevent the entire shielding plate 200 from flipping or tilting in the initial state, the second linear drive assembly 400 can drive the snap-fit plate 211 to move toward the first slot 1021 until the snap-fit plate 211 is fully inserted into the first slot 1021 to achieve snap-fit, thereby preventing the entire shielding plate 200 from flipping.
[0044] In some embodiments, a second slot 1022 is provided on the side wall of the groove 102 along the first direction X.
[0045] Please continue reading. Figure 2 , Figure 3 as well as Figure 4 As shown, when the baffle 200 is set horizontally, in order to prevent the baffle 200 from continuing to flip downward and not being able to be in a horizontal state, a second slot 1022 is opened on the side wall of the groove 102 in the first direction X. The snap-fit plate 211 is also in a horizontal state. Then, the snap-fit plate 211 can be driven by the second linear drive assembly 400 to move towards the second slot 1022 until the snap-fit plate 211 extends into the second slot 1022 to achieve snap-fit. At this time, in the snap-fit state of the snap-fit plate 211 and the second slot 1022, the baffle 200 is maintained and in a horizontal state, which satisfies the condition for the snap-fit plate 211 to extend.
[0046] In some embodiments, a second groove 202 is provided in the second plate 220, and the sliding plate 221 is slidably disposed in the second groove 202; the first linear drive assembly 300 includes a first rotating shaft 310 and a first lead screw 320, the first rotating shaft 310 is rotatably disposed in the second plate 220, the first lead screw 320 is disposed in the second groove 202, the first lead screw 320 is connected to the sliding plate 221 in a transmission, and a first drive member 330 is provided at the end of the first rotating shaft 310 away from the first lead screw 320.
[0047] See Figure 2 , Figure 3 as well as Figure 4 As shown, when it is necessary to move the sliding plate 221 along the second sliding groove 202, the first driving member 330 only needs to drive the first lead screw 320 to rotate through the first rotating shaft 310. The sliding plate 221 can be moved in different directions by the different rotation directions of the first lead screw 320. In this embodiment, the first driving member 330 can be a handwheel, which drives the first rotating shaft 310 to rotate, thereby driving the first lead screw 320 to rotate.
[0048] It is understandable that in order to enable the sliding plate 221 to move along the second slide groove 202 under the action of the first lead screw 320, the sliding plate 221 should have a corresponding threaded hole to cooperate with the first lead screw 320.
[0049] In some embodiments, the snap-fit plate 211 includes a transmission part 2111 slidably disposed in the first groove 201, and the end of the transmission part 2111 is provided with a snap-fit part 2112.
[0050] like Figure 2 , Figure 3 as well as Figure 4 As shown, the snap-fit plate 211 is divided into a transmission part 2111 and a snap-fit part 2112. Specifically, the snap-fit part 2112 is used to snap into the first snap-fit groove 1021 or the second snap-fit groove 1022 as needed. The transmission part 2111 is used to make a transmission connection with the second linear drive assembly 400 to realize the transmission of force. The transmission part 2111 is slidably disposed in the first slide groove 201, and the snap-fit part 2112 is disposed at the end of the transmission part 2111 away from the direction of the second linear drive assembly 400.
[0051] The second linear drive assembly 400 includes a second rotating shaft 410 rotatably mounted on the first plate 210, a second lead screw 420 provided at the end of the second rotating shaft 410 facing the snap-fit plate 211, and a second drive member 430 provided at the end of the second rotating shaft 410 away from the second lead screw 420.
[0052] See Figures 2 to 4As shown, the transmission part 2111 has a thread that engages with the second lead screw 420. The second lead screw 420 and the threaded hole cooperate to transmit force. Specifically, when it is necessary to drive the transmission part 2111 and the locking part 2112 to move, the second driving member 430 transmits power through the second rotating shaft 410 to drive the second lead screw 420 to rotate, thereby driving the transmission part 2111 to move in the first slide groove 201, thereby driving the locking part 2112 to move.
[0053] For example, the second drive element 430 can be a handwheel or other hand-held component.
[0054] In some embodiments, a handrail 500 is fixedly provided on one side of the base plate 100 along the second direction Y.
[0055] See Figures 1 to 3 As shown, in order to push the trolley, a handrail 500 is fixedly installed on one side of the base plate 100, so that the staff can hold the handrail 500 to push the trolley. It is understood that the position of the handrail 500 should not affect the rotation of the cover plate 200.
