Description

Technical Field

[0001] The utility model relates to the technical field of article transportation, and in particular to a cabinet fixing device and an article loading platform. Background Art

[0002] Currently, when a cabinet, such as an electrical cabinet, is assembled on a production line, it is usually carried on a loading platform such as a pallet. In this way, when the electrical cabinet needs to be moved later, a forklift or other transportation tool can be used to directly move the pallet.

[0003] In the related art, a plurality of positioning blocks are provided on a loading platform such as a pallet. When a cabinet such as an electrical cabinet is placed on the pallet, it is located between the plurality of positioning blocks and is limited and positioned in the horizontal direction by the plurality of positioning blocks.

[0004] However, the inventors have realized that in actual use, for a relatively tall and thin electrical cabinet, if the limit and positioning are only achieved in the horizontal direction, the electrical cabinet is prone to move upward or even fall over during the subsequent assembly or transportation process. At the same time, when the components inside the electrical cabinet are automatically assembled on the assembly line, the vertical position of the electrical cabinet changes, which may cause difficulties in installing the components inside the electrical cabinet. At this time, the position of the electrical cabinet needs to be adjusted manually, which affects the production efficiency. Utility Model Content

[0036] The embodiment of the utility model discloses a cabinet fixing device 1. Figure 1 , 2 As shown, the cabinet fixing device 1 includes a support base 11, a driving component 12 and a rotating buckle 13. The support base 11 is used to be fixedly connected to the loading platform, the rotating buckle 13 is rotatably connected to the support base 11, and the driving component 12 is used to drive the rotating buckle 13 to rotate relative to the support base 11; the rotating buckle 13 has a locked state and an unlocked state. When the rotating buckle 13 is configured to pass through the first hole structure 41 of the cabinet 4, the rotating buckle 13 is in an unlocked state; when the rotating buckle 13 is configured to be vertically abutted against the cabinet 4 at one end toward the support base 11, the rotating buckle 13 is in a locked state.

[0037] In this embodiment, the shape of the support base 11 can be square, circular or oval, etc. There is no limitation here, and it depends on actual needs.

[0038] In this embodiment, the cabinet 4 can be an electrical cabinet, an air cabinet, etc. Figure 8 As shown, the bottom wall of the cabinet 4 is provided with a first hole structure 41, and the first hole structure 41 can be a waist-shaped hole or a long hole. There is no limitation here, and it depends on actual needs.

[0039] By adopting the above technical solution, when the cabinet 4 needs to be placed on the loading platform, first ensure that the rotating buckle 13 is in the unlocked state. At this time, the rotating buckle 13 is in a position that can pass through the first hole structure 41 of the cabinet 4. Then, the cabinet 4 is slowly lowered from top to bottom until the bottom of the cabinet 4 is supported on the support seat 11. At this time, the rotating buckle 13 just passes through the first hole structure 41. Finally, the driving component 12 is enabled to drive the rotating buckle 13 to rotate relative to the support seat 11 until the rotating buckle 13 is in a locked state. At this time, the end of the rotating buckle 13 facing the support seat 11 is vertically against the cabinet 4; when the cabinet 4 has a tendency to move upward, the rotating buckle 13 can play a limiting role, thereby effectively improving the problem of the cabinet 4 moving upward, thereby reducing the probability of manual adjustment of the position of the cabinet 4 when the components inside the cabinet 4 are automatically assembled, thereby improving production efficiency.

[0040] Optionally, the driving assembly 12 includes a first transmission shaft 121, a gear transmission mechanism 122 and a rotating seat 123. The first transmission shaft 121 and the rotating seat 123 are respectively rotatably connected to the support seat 11. One end of the first transmission shaft 121 is transmission-connected to the rotating seat 123 through the gear transmission mechanism 122. The other end of the first transmission shaft 121 is used for driving connection with the auxiliary power equipment. The rotating buckle 13 is supported at the rotating seat 123.

[0041] like Figure 1 As shown, the first transmission shaft 121 is rotatably connected to the support seat 11. Specifically, a mounting channel is provided inside the support seat 11, one end of the first transmission shaft 121 is rotatably arranged in the mounting channel, and the other end of the first transmission shaft 121 is located outside the support seat 11. The rotating seat 123 is rotatably connected to the support seat 11. Specifically, the support seat 11 is provided with a mounting groove communicated with the mounting channel, and the rotating seat 123 is rotatably arranged in the mounting groove. One end of the first transmission shaft 121 located in the mounting channel is transmission-connected to the rotating seat 123 through a gear transmission mechanism 122. The rotating buckle 13 is supported on the top of the rotating seat 123, and there is a gap with the upper surface of the support seat 11.

[0042] In this way, when an auxiliary power device such as a manipulator clamps the first transmission shaft 121, the manipulator can drive the first transmission shaft 121 to rotate relative to the support seat 11, and drive the rotating seat 123 to rotate relative to the support seat 11 under the transmission of the gear transmission mechanism 122, and finally realize the rotation of the rotating buckle 13, so that the rotating buckle 13 can switch between a locked state and an unlocked state.

[0043] In other embodiments, the first transmission shaft 121 and the rotating shaft 22 may also be disposed on the outer side of the support seat 11 through brackets respectively.

[0044] Optionally, the rotation axis of the first transmission shaft 121 intersects with the rotation axis of the rotating seat 123; the gear transmission mechanism 122 includes a first bevel gear 1221 and a second bevel gear 1222, the first bevel gear 1221 is coaxially connected to the first transmission shaft 121, and the second bevel gear 1222 is sleeved on the circumferential outer wall of the rotating seat 123, and the first bevel gear 1221 and the second bevel gear 1222 are meshed for transmission.

[0045] like Figure 1 As shown, the rotation axis of the first transmission shaft 121 is perpendicular to the rotation axis of the rotating seat 123; the first bevel gear 1221 of the gear transmission mechanism 122 is coaxially connected to one end of the first transmission shaft 121 toward the rotating seat 123, and the second bevel gear 1222 is sleeved on the circumferential outer wall of the rotating seat 123, and the first bevel gear 1221 and the second bevel gear 1222 are meshed for transmission.

[0046] In this way, when the auxiliary power device such as a manipulator drives the first transmission shaft 121 to rotate in the vertical plane, the rotating seat 123 can be driven to rotate in the horizontal plane through the reversal of the first bevel gear 1221 and the second bevel gear 1222, and finally the rotation of the rotating buckle 13 is realized.

[0047] Further, the transmission ratio of the first bevel gear 1221 and the second bevel gear 1222 is not specifically limited and is determined according to actual needs. For example, the transmission ratio of the first bevel gear 1221 and the second bevel gear 1222 is 2:1. In this way, when the first transmission shaft 121 rotates 90 degrees, the rotating buckle 13 can rotate 45 degrees.

[0048] Optionally, the driving assembly 12 further includes a driving handle 124 , and the driving handle 124 is fixedly connected to the first transmission shaft 121 .

[0049] like Figure 1 As shown, the driving handle 124 is fixedly connected to the first transmission shaft 121. Specifically, the driving handle 124 is vertically arranged with the first transmission shaft 121, and one end of the driving handle 124 is clamped on the first transmission shaft 121 through a clamping block 125. In this way, the operator can realize the rotation of the first transmission shaft 121 by operating the driving handle 124.

[0050] Optionally, the driving assembly 12 also includes a second transmission shaft 126, a third bevel gear 127 and a fourth bevel gear 128. The support seat 11 is provided with a plurality of rotating seats 123 along the first direction, and the plurality of rotating seats 123 are respectively sleeved with second bevel gears 1222. The second transmission shaft 126 is rotatably connected to the support seat 11, and the two ends of the second transmission shaft 126 are coaxially connected to the third bevel gear 127 and the fourth bevel gear 128, respectively. One end of the second transmission shaft 126 is meshed with the second bevel gear 1222 on one rotating seat 123 through the third bevel gear 127, and the other end of the second transmission shaft 126 is meshed with the second bevel gear 1222 on another rotating seat 123 through the fourth bevel gear 128.

[0051] like Figure 1 , 2 As shown, the support seat 11 is in the shape of a rectangular parallelepiped, and the support seat 11 is provided with two rotating seats 123 along its length direction, and the two rotating seats 123 are respectively sleeved with second bevel gears 1222; the second transmission shaft 126 is rotatably connected to the support seat 11, specifically, the second transmission shaft 126 is located in the installation channel between the two rotating seats 123; the two ends of the second transmission shaft 126 are coaxially connected to the third bevel gear 127 and the fourth bevel gear 128, respectively, one end of the second transmission shaft 126 is meshed with the second bevel gear 1222 on one rotating seat 123 through the third bevel gear 127, and the other end of the second transmission shaft 126 is meshed with the second bevel gear 1222 on the other rotating seat 123 through the fourth bevel gear 128.

[0052] In this way, when one rotating seat 123 rotates relative to the supporting seat 11, under the transmission of the second bevel gear 1222, the third bevel gear 127, the second transmission shaft 126 and the fourth bevel gear 128, the other rotating seat 123 can also rotate relative to the supporting seat 11, thereby realizing the synchronous rotation of multiple rotating seats 123, and then realizing the synchronous rotation of multiple rotating buckles 13.

[0053] In this embodiment, the number of the mounting bases may also be three or four, etc. There is no limitation here, and it depends on actual needs.

[0054] In other embodiments, the first transmission shaft 121 and the second transmission shaft 126 as well as two adjacent second transmission shafts 126 may be coaxially connected, in which case the number of corresponding bevel gears may be reduced.

[0055] Optionally, the cabinet fixing device 1 further includes a bearing 16, and the first transmission shaft 121 and the second transmission shaft 126 are rotatably arranged in the mounting channel in the support seat 11 through the bearing 16. In this way, when the first transmission shaft 121 and the second transmission shaft 126 rotate, the bearing effectively reduces the rotation damping of the two.

[0056] Optionally, the cabinet fixing device 1 further includes a positioning pin 14 , which is disposed on the support seat 11 , and is used to pass through the second hole structure 42 of the cabinet 4 .

[0057] like Figure 2 As shown, the positioning pin 14 is disposed on the top of the support seat 11; Figure 8 As shown, the bottom wall of the cabinet 4 is provided with a penetrating second hole structure 42; when the positioning pin 14 passes through the second hole structure 42, the positioning pin 14 is tightly fitted with the inner wall of the second hole structure 42 of the cabinet 4. In this way, when the cabinet 4 is placed on the loading platform, the positioning pin 14 cooperates with the second hole structure 42, which can not only realize the rapid positioning of the cabinet 4 and the cabinet fixing device 1, but also realize the horizontal limit of the cabinet 4.

[0058] In this embodiment, the positioning pin 14 is integrally formed with the support seat 11 or detachably connected. There is no limitation here, and it depends on actual needs.

[0059] In this embodiment, when the positioning pin 14 is detachably connected to the support seat 11, the two are plugged and fixed. Specifically, the support seat 11 is provided with a plug hole 111, and one end of the positioning pin 14 is interference-fitted with the plug hole 111; at the same time, the circumferential side wall of the positioning pin 14 is provided with a clamping plate 15, and the clamping plate 15 is provided with at least two grabbing holes. The upper surface of the support seat 11 is provided with a mounting groove 112 that matches the clamping plate 15, and the clamping plate 15 is located in the mounting groove 112. In this way, when the positioning pin 14 is installed and removed, a clamping tool such as a clamp can clamp the grabbing hole on the clamping plate 15, so as to facilitate the rapid installation and removal of the positioning pin 14.

[0060] Optionally, the cabinet fixing device 1 also includes a flipping assembly 2, which includes a fixed seat 21, a rotating shaft 22 and a rotating arm 23. The fixed seat 21 is used to be fixedly connected to the loading platform, the rotating shaft 22 is rotatably connected to the fixed seat 21, and the two ends of the rotating arm 23 are respectively fixedly connected to the rotating shaft 22 and the support seat 11.

[0061] like Figure 6 As shown, the fixing seat 21 is fixedly connected to the base 3 of the loading platform, wherein the projection of the fixing seat 21 on the base 3 is in a U-shape; Figure 3 As shown, the rotating shaft 22 is rotatably connected to the fixed seat 21. Specifically, the two ends of the rotating shaft 22 are respectively rotatably connected to the opposite ends of the U-shaped fixed seat 21, and one end of the rotating shaft 22 is located on the outside of the fixed seat 21; two rotating arms 23 are provided, and the two ends of the two rotating arms 23 are respectively fixedly connected to the rotating shaft 22 and the support seat 11.

[0062] In this way, when an auxiliary power device such as a manipulator drives the rotating shaft 22 to rotate in the vertical plane, the supporting base 11 can be driven to rotate in the vertical plane through the rotating arm 23 until the rotating buckle 13 on the supporting base 11 is located directly above the supporting base 11. In this way, by changing the height of the supporting base 11, it is possible to adapt to a cabinet 4 with a bottom having different height planes.

[0063] Alternatively, if Figure 3 , 4 As shown, the flip assembly 2 further includes a limit seat 24 and a first threaded member 25. The limit seat 24 is connected to the support seat 11. The limit seat 24 is provided with a through hole structure 242 and a first threaded hole structure 241 communicating with the through hole structure 242. The rotation shaft 22 passes through the through hole structure 242. The first threaded member 25 is threadedly connected with the first threaded hole structure 241. The first threaded member 25 is used to extend into the through hole structure 242 and abut against the rotation shaft 22. In this way, by rotating the first threaded member 25, the friction between the first threaded member 25 and the rotation shaft 22 can be changed, thereby adjusting the rotation damping of the rotation shaft 22.

[0064] Alternatively, if Figure 3 , 5 As shown, the flip assembly 2 further includes a second threaded member 26, the fixing seat 21 is provided with a second threaded hole structure 211, the second threaded member 26 is threadedly connected to the second threaded hole structure 211, the second threaded member 26 is located on the rotation path of the rotating arm 23, and the second threaded member 26 is used to abut against the rotating arm 23. In this way, by rotating the second threaded member 26, the friction between the second threaded member 26 and the rotating shaft 22 can be changed, thereby adjusting the maximum rotation angle of the rotating shaft 22.

[0065] Another embodiment of the present invention discloses a loading platform. Figure 6 , 7 As shown, the loading platform includes a base 3 and the cabinet fixing device 1 as described above, and at least one cabinet fixing device 1 is provided on the base 3.

[0066] When the loading platform is used on a production line such as a roller line or a double-speed chain, the cabinet 4 can be quickly and reliably locked and fixed in the horizontal and vertical directions. Since the position of the cabinet 4 on the loading platform is fixed, the components inside the cabinet 4 can be reliably and automatically assembled on the production line.

[0067] In addition, the first transmission shaft 121 and the second transmission shaft 126 of the cabinet fixing device 1 can cooperate with auxiliary power equipment such as a manipulator to realize unmanned operation. In addition, the flip assembly 2 allows the height of the loading platform to be reduced to a minimum when the double-layer production line is reflowed, thereby maximizing the reduction of the overall height of the double-layer production line, which not only reduces the manufacturing cost, but also facilitates the online assembly work of personnel and the subsequent equipment maintenance.

[0068] Optionally, there are two fixing devices, wherein the support base 11 of one cabinet fixing device 1 is fixedly connected to the base 3 , and the support base 11 of the other cabinet fixing device 1 is fixedly connected to the base 3 via the flip assembly 2 of the cabinet fixing device 1 .

[0069] like Figure 6 , 7 As shown, the base 3 is in the shape of a rectangular parallelepiped. Along the length direction of the base 3, two cabinet fixing devices 1 are arranged at intervals. The support base 11 of one cabinet fixing device 1 is fixedly connected to the base 3, and the support base 11 of the other cabinet fixing device 1 is fixedly connected to the base 3 through the flip assembly 2 of the cabinet fixing device 1. In this way, when transporting a cabinet 4 with a step structure at the bottom, one cabinet fixing device 1 is directly connected to the bottom of the cabinet 4, and the other cabinet fixing device 1 needs to be flipped to a preset height to be connected to the bottom of the cabinet 4. The final effect is as follows Fig. 9 shown.

[0070] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
