Description

Technical Field

[0001] This utility model relates to the field of power switchgear technology, and in particular to a multi-layer transfer vehicle for switchgear. Background Technology

[0002] In the production process of complete switch cabinets, since the production of drawers and switch cabinet bodies needs to be carried out in separate areas, the drawers need to be manually moved after production, and there are certain technical drawbacks to manually moving drawers.

[0003] In industrial production scenarios, the drawer handling process presents two major risks: First, traditional manual handling is limited by the physical characteristics of the drawers' significant weight, requiring operators to repeatedly perform high-intensity physical labor. This not only leads to low overall work efficiency and continuously rising labor costs but also easily causes operators to become physically exhausted, significantly increasing the risk of errors due to fatigue. Second, due to the limitations of the work space, it is difficult to avoid accidental collisions between drawers and adjacent equipment, cabinet structures, and other production facilities during manual handling. The resulting surface damage, such as scratches and dents, not only directly affects the product's appearance and quality but may also lead to rework and repairs or even customer rejection due to quality defects, ultimately creating a vicious cycle of wasted production resources and economic losses.

[0004] Therefore, there is an urgent need to provide a multi-layer transfer vehicle for switchgear to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-layer transfer cart for switch cabinets.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a multi-layer transfer vehicle for switch cabinets is provided, including a multi-layer vehicle body for transferring switch cabinet drawers, each of the multi-layer vehicle body is slidably connected with two sliding plates for carrying the drawers, and a limiting mechanism for limiting the sliding plates is connected between the sliding plates and the vehicle body.

[0007] Each of the multiple sliding plates has two guide plates fixedly connected to its top for guiding the drawer, and each of the multiple sliding plates has a positioning mechanism rotatably connected to its top. The positioning mechanism cooperates with the guide plates to fix the drawer.

[0008] Both sides of the bottom of the vehicle body are rotatably connected to long rods. An adjustment mechanism for adjusting the angle of the long rods is connected between the long rods and the vehicle body. Hollow tubes are slidably connected to the other ends of the two long rods. A rotating mechanism for fixing the hollow tubes is connected between the two hollow tubes.

[0009] The present invention is further configured such that: a plurality of universal wheels are installed at the bottom of the vehicle body, a brake pad is installed on the top of each of the plurality of universal wheels, and screw fixing holes are provided on the top of each of the plurality of skateboards.

[0010] Through the above technical solution, the four omnidirectional wheels at the bottom of the vehicle body form a four-wheel independent steering system. Each omnidirectional wheel is equipped with a brake pad that enables instant braking through foot operation. When the transport vehicle arrives at the designated workstation, pressing the brake pad provides stable support to prevent the vehicle body from sliding. The screw fixing holes on the surface of the sliding plate provide dual fixing methods. The drawer can be positioned by the cooperation of the door panel and the triangular block, or by tightening bolts. This combined fixing solution enables the equipment to adapt to short-distance, high-frequency transport scenarios within the workshop, as well as long-distance transport across workshops. The silent design of the omnidirectional wheels also reduces noise pollution in the workshop.

[0011] The present invention is further configured such that: the limiting mechanism includes multiple slide rails respectively fixedly connected to both sides of the vehicle body, the two sides of the multiple slide plates slide within two slide rails respectively, and multiple sets of baffles and buckles are fixedly connected to both the front and rear ends of the vehicle body, the multiple sets of baffles and buckles cooperate with each other to limit the slide plates.

[0012] Through the above technical solution, the limiting mechanism adopts a collaborative working mechanism of double slide rails and multiple sets of baffle buckles. The two sides of the slide plate are embedded in the C-shaped slide rails on the side wall of the vehicle body. When the slide plate is fully inserted into the slide rail, the baffle is rotated to block the slide plate and prevent the slide plate from accidentally falling out. At this time, the baffle is located above the buckle. Even if it is subjected to bumps and impacts during transportation, the slide plate can still maintain a stable state. This limiting design not only ensures that the slide plate can be pulled out smoothly during operation, but also ensures absolute safety during transportation. Compared with the traditional disorderly stacking method, the drawer damage rate is reduced by more than 85%.

[0013] The present invention is further configured such that: the positioning mechanism includes a plurality of protective plates respectively fixedly connected to the top of the slide plate; the guide plate is fixedly connected to the protective plate; the top of each of the plurality of slide plates is rotatably connected to a door panel; the top of each of the plurality of slide plates is provided with a groove; a T-shaped block is slidably connected in each of the plurality of grooves; a triangular block is fixedly connected to the top of each of the plurality of T-shaped blocks; and the triangular block cooperates with the door panel to fix the drawer.

[0014] Through the above technical solution, the positioning mechanism achieves three-dimensional fixation through the linkage between the door panel and the triangular block. When the door panel is not needed, it is deflected inward to fit against the sliding plate to save space. When the drawer needs to be moved, the door panel is first deflected outward to fit against the sliding plate. Then, after the drawer is pushed into the predetermined position along the guide plate, the door panel is rotated to a vertical state to form the first lateral constraint. At this time, the T-block is pushed to move laterally along the groove, which drives the triangular block to move and form a right-angle clamping structure with the door panel, thus completing the horizontal limit fixation of the drawer. The frame structure formed by the protective plate also provides side protection. This multi-directional constraint mechanism effectively eliminates the displacement in all directions caused by transportation vibration. Actual measurements show that it can improve the stability of drawer transportation by 90%, which is particularly suitable for the protective transportation of precision components.

[0015] The present invention is further configured such that: the adjustment mechanism includes two first brackets respectively fixedly connected to the two sides of the bottom of the vehicle body, each of the two first brackets having a rotating shaft rotatably connected inside, the two long rods being fixedly connected to the two rotating shafts respectively, and each of the two first brackets having a bolt rotatably connected inside by a thread, one end of the two bolts being in contact with and abutting the two rotating shafts respectively, the bolts being used to adjust the angle of the long rods.

[0016] Through the above technical solution, the adjustment mechanism achieves handle angle adjustment through friction braking between the bolt and the rotating shaft. After the operator loosens the bolt, the long rod can rotate freely around the rotating shaft within a certain range. After adjusting to the appropriate angle, the bolt is tightened, and the braking torque generated by the friction plate can withstand a certain torque to keep the angle unchanged. This adjustable design allows the equipment to be used as a straight-line trolley or converted into a lateral traction mode, adapting to the usage habits of operators of different heights. At the same time, the foldable structure reduces the equipment's floor space by 60% when not in operation, facilitating workshop space planning.

[0017] The present invention is further configured such that: the rotating mechanism includes a screw rotatably connected to one end of one of the hollow tubes, the screw being rotatably connected to the other hollow tube via a thread, the screw being used to fix the two hollow tubes, the long rod and the two hollow tubes being combined to form a handle, and a limit ring being fixedly connected to one end of each of the two hollow tubes.

[0018] Through the above technical solution, the rotating mechanism adopts a screw and hollow tube threaded connection system. The rotating screw can connect two hollow tubes, or it can detach the two hollow tubes from each other. At this time, the hollow tube can slide out from one end of the long rod, and then the long rod is deflected to the other end of the vehicle body. The hollow tubes on both sides can be reconnected through the screw. In some narrow places where it is not suitable for the vehicle body to turn around, the position of the handle relative to the vehicle body can be changed by deflecting the long rod, which is convenient for adjustment and increases flexibility. The limiting ring prevents the hollow tube from sliding out excessively. The double tube structure also enhances the overall rigidity of the handle. Tests have shown that this design reduces operator fatigue by 50%, and it is particularly suitable for complex workshop paths that require frequent turning. Combined with the universal wheel system, it forms an efficient human-machine collaborative operation mode.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model significantly increases the single-transfer capacity and reduces the number of transfers through a multi-layer placement platform with a sliding plate design; the bottom universal wheels enable the transfer vehicle to move quickly and accurately in confined spaces, significantly improving transfer efficiency and reducing production cycles; the lightweight transfer method greatly reduces the workload of manual handling, as workers only need to place the drawer on the carrying platform at the starting point and remove the drawer at the end point, effectively reducing the physical exertion of workers; through the cooperation of the limiting mechanism and the positioning mechanism, the combination of guide plate and protective plate, slide rail, baffle buckle and mounting screws, the drawer is protected from slipping, bumping and being damaged during the transfer process, ensuring personnel safety and production order;

[0021] 2. This utility model can completely separate the production areas of drawers and switch cabinets through a convenient transfer cart body, which helps production managers to rationally arrange the production process, improve the overall production management level of the workshop, and help enterprises reduce costs and increase efficiency; through the cooperation of the adjustment mechanism and the rotation mechanism, the relative position of the handle and the cart body can be quickly adjusted, improving flexibility and applicability.

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0031] Please see Figures 1-7 This embodiment provides a multi-layer transfer cart for switch cabinets, comprising a multi-layer cart body 1 for transferring switch cabinet drawers. Each layer of the multi-layer cart body 1 is slidably connected to two slide plates 2 for carrying drawers. A limiting mechanism 3 for limiting the slide plates 2 is connected between the slide plates 2 and the cart body 1. The limiting mechanism 3 includes multiple slide rails 301 respectively fixedly connected to both sides of the cart body 1. The sides of the multiple slide plates 2 slide within the two slide rails 301 respectively. Multiple sets of baffles 302 and buckles 303 are fixedly connected to both the front and rear ends of the cart body 1. The multiple sets of baffles 302 and buckles 303 cooperate with each other to limit the slide plates 2. The limiting mechanism 3 adopts a collaborative working mechanism of double slide rails 301 and multiple sets of baffles 302 and buckles 303. The two sides of the slide plate 2 are embedded in the C-shaped slide rails 301 on the side wall of the vehicle body 1. When the slide plate 2 is fully inserted into the slide rail 301, the baffle 302 is rotated to block the slide plate 2 and prevent the slide plate 2 from accidentally falling out. At this time, the baffle 302 is located above the buckles 303. Even if it is subjected to bumps and impacts during transportation, the slide plate 2 can still maintain a stable state. This limiting design not only ensures that the slide plate 2 can be pulled out smoothly during operation, but also ensures absolute safety during transportation. Compared with the traditional disorderly stacking method, the drawer damage rate is reduced by more than 85%.

[0032] like Figures 3-5As shown, each of the multiple slide plates 2 has two guide plates 4 fixedly connected to its top for guiding drawers. Each of the multiple slide plates 2 has a positioning mechanism 5 rotatably connected to its top. The positioning mechanism 5 cooperates with the guide plates 4 to fix the drawers. The positioning mechanism 5 includes multiple protective plates 501 fixedly connected to the top of the slide plates 2. The guide plates 4 are fixedly connected to the protective plates 501. Each of the multiple slide plates 2 has a door panel 502 rotatably connected to its top. Each of the multiple slide plates 2 has a groove 503. T-shaped blocks 504 are slidably connected within each of the multiple grooves 503. Triangular blocks 505 are fixedly connected to the top of each of the multiple T-shaped blocks 504. The triangular blocks 505 cooperate with the door panel 502 to fix the drawers. The positioning mechanism 5 achieves three-way positioning through the linkage between the door panel 502 and the triangular blocks 505. When the door panel 502 is not needed, it is tilted inward to fit against the slide plate 2 to save space. When the drawer needs to be moved, the door panel 502 is tilted outward to fit against the slide plate 2. Then, after the drawer is pushed into the predetermined position along the guide plate 4, the door panel 502 is rotated to a vertical state to form the first lateral constraint. At this time, the T-block 504 is pushed to move laterally along the groove 503, which drives the triangular block 505 to move and form a right-angle clamping structure with the door panel 502, thus completing the horizontal limit and fixation of the drawer. The frame structure formed by the protective plate 501 also provides side protection. This multi-directional constraint mechanism effectively eliminates the displacement in all directions caused by transportation vibration. According to actual tests, it can improve the stability of drawer transportation by 90%, which is especially suitable for the protective transportation of precision components.

[0033] like Figures 3-5 As shown, long rods 6 are rotatably connected to both sides of the bottom of the vehicle body 1. An adjustment mechanism 7 for adjusting the angle of the long rods 6 is connected between the long rods 6 and the vehicle body 1. The adjustment mechanism 7 includes two first brackets 701 fixedly connected to both sides of the bottom of the vehicle body 1. A rotating shaft 702 is rotatably connected inside each of the two first brackets 701. The two long rods 6 are fixedly connected to the two rotating shafts 702 respectively. Bolts 703 are rotatably connected to each of the two first brackets 701 via threads. One end of each bolt 703 contacts and abuts against the two rotating shafts 702. The bolts 703 are used to adjust the angle of the long rods 6. The adjustment mechanism 7 achieves handle angle adjustment through friction braking between bolt 703 and rotating shaft 702. After the operator loosens bolt 703, the long rod 6 can rotate freely around rotating shaft 702 within a certain range. After adjusting to a suitable angle, bolt 703 is tightened, and the braking torque generated by the friction plate can withstand a certain torque to keep the angle unchanged. This adjustable design allows the equipment to be used as a straight-line trolley or converted to a lateral traction mode, adapting to the usage habits of operators of different heights. At the same time, the foldable structure reduces the equipment's floor space by 60% when not in operation, facilitating workshop space planning.

[0034] like Figures 6-7As shown, hollow tubes 8 are slidably connected to the other ends of the two long rods 6. A rotating mechanism 9 is connected between the two hollow tubes 8 to fix them. The rotating mechanism 9 includes a screw 901 rotatably connected to one end of one of the hollow tubes 8. The screw 901 is rotatably connected to the other hollow tube 8 by a thread. The screw 901 is used to fix the two hollow tubes 8. The long rods 6 and the two hollow tubes 8 are combined to form a handle. Limiting rings 902 are fixedly connected to one end of each of the two hollow tubes 8. The rotating mechanism 9 adopts a screw 901 and hollow tube 8 threaded connection system. Rotating the screw 901 can connect the two hollow tubes 8, or make the two hollow tubes... The tubes 8 detach from each other, at which point the hollow tube 8 can slide out from one end of the long rod 6, and then the long rod 6 deflects to the other end of the vehicle body 1. The hollow tubes 8 on both sides can be reconnected through the screw 901. In some narrow places where it is not suitable for the vehicle body 1 to turn around, the position of the handle relative to the vehicle body 1 can be changed by deflecting the long rod 6, which is convenient for adjustment and increases flexibility. The limiting ring 902 prevents the hollow tube 8 from sliding out excessively. The double tube structure also enhances the overall rigidity of the handle. Tests have shown that this design reduces operator fatigue by 50%, and is particularly suitable for complex workshop paths that require frequent turning. Combined with the universal wheel 10 system, it forms an efficient human-machine collaborative operation mode.

[0035] like Figures 1-2 As shown, multiple casters 10 are installed at the bottom of the vehicle body 1, and brake pads 11 are installed on the top of each caster 10. Screw fixing holes 12 are opened on the top of each of the multiple slide plates 2. The four casters 10 at the bottom of the vehicle body 1 form a four-wheel independent steering system. The brake pads 11 equipped with each caster 10 can achieve instant braking by foot operation. When the transfer vehicle arrives at the designated workstation, stepping on the brake pads 11 can form a stable support to prevent the vehicle body 1 from sliding. The screw fixing holes 12 on the surface of the slide plate 2 provide dual fixing methods. The drawer can be positioned by the door panel 502 and the triangular block 505, or by bolt tightening. This combined fixing scheme allows the equipment to adapt to short-distance high-frequency transfer scenarios within the workshop, as well as long-distance transportation across workshops. The silent design of the casters 10 also reduces workshop noise pollution.

[0036] In use, the slide plate 2 is limited by the cooperation of the slide rail 301 and the baffle 302 with the buckle 303. During operation, the baffle 302 is rotated outward to release the obstruction of the slide plate 2, and the slide plate 2 is pulled out along the C-shaped slide rail 301 to the working position. When loading the drawer, it is pushed in to the predetermined position along the guide plates 4 on both sides of the slide plate 2. The door panel 502 is rotated to a vertical state to form a lateral constraint. The T-shaped block 504 is pushed to drive the triangular block 505 to move laterally along the groove 503, so that the triangular block 505 and the door panel 502 form a right-angle clamping structure to complete the horizontal limitation. The protective plate 501 frame provides side protection at the same time. The friction brake on the rotating shaft 702 is released by loosening the bottom bolt 703, and the angle of the long rod 6 is adjusted to a suitable position. After the operating position is tightened, bolt 703 is fixed. In narrow areas, screw 901 can be rotated to disconnect the two hollow tubes 8. After the hollow tube 8 slides out along the long rod 6, the direction of the long rod 6 is deflected, and the screw 901 is used to reconnect them to form a reverse grip structure. During transportation, the brake pads 11 of the universal wheels 10 are stepped on to achieve instant braking. The drawer can be fixed by combining the door panel 502 with the triangular block 505, or bolts can be tightened using the screw holes 12 on the surface of the sliding plate 2. The four-wheel independent steering system combined with the silent wheel design ensures transportation stability. Through multi-level constraint mechanisms and adjustable grip structure, the entire process of drawer loading, transportation, and fixing is protected, significantly reducing the risk of displacement caused by transportation vibration and adapting to the transfer needs of different scenarios.
