Description

Technical Field

[0001] This utility model relates to the field of logistics vehicle technology, specifically to a transportation and storage vehicle for an automobile bumper processing workshop. Background Technology

[0002] In automobile production workshops, after car bumpers are injection molded and painted on the painting line, they need to be transported to the assembly workshop by transport vehicles. To improve production efficiency and shorten the operation time of each process step, the choice of transport vehicles is crucial. Current car bumper transport vehicles are generally multi-layered, with each layer secured by support rods, and the bumpers are arranged symmetrically on both sides in a balanced tower-like configuration. After the operator fills one side of the transport vehicle's rack, the vehicle is turned around to continue loading. A four-layered transport vehicle can carry a total of eight bumpers on both sides. This design doesn't maximize the use of the loading vehicle's overall space, reducing loading efficiency each time. It also necessitates designing loading vehicles of different sizes for different car bumpers, requiring a wider variety of vehicles and increasing the overall number of loading vehicles. A search revealed a Chinese patent with authorization announcement number CN207902495U, which discloses a high-efficiency bumper carrier, including a loading frame with one or more layers, separated by partitions between each pair of layers. The loading frame has a roof, back panel, and side panels. The inner walls of the roof, back panel, and side panels, as well as the sides of the partitions, have anti-collision layers. The upper surface of the partitions also has a limiting structure and a protective layer. This increases transportation efficiency, reduces transportation costs, ensures material supply to the assembly plant, and increases company output. It also prevents the bumpers from getting wet from rain and protects them from impacts during transportation, reducing damage caused by transport.

[0003] However, in actual use, due to the fixed internal structure, the car bumpers need to be manually placed one by one in different positions to achieve the stacking effect. This method is not only time-consuming and labor-intensive, but also causes collision damage to the car bumpers due to the lack of buffer facilities. Furthermore, the same procedure is required to remove the car bumpers later, which is quite inconvenient. Utility Model Content

[0004] To address the problem that existing storage containers are not suitable for stacking car bumpers, this utility model provides a transportation and storage container for car bumper processing workshops.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A transport and storage vehicle for an automotive bumper processing workshop includes a storage frame with a housing mounted at its bottom; a lifting mechanism disposed on one side of the storage frame and the housing, the lifting mechanism including a top plate and a bottom plate, the top plate being mounted on the outer wall of the storage frame and the bottom plate being mounted on the outer wall of the housing, a lead screw rotatably connecting the top plate and the bottom plate, one end of the lead screw being threadedly connected to a lifting plate, a slot being provided on one side of the storage frame that engages with one side of the lifting plate, the lifting plate being slidably connected inside the storage frame; and a placement rack stacked on the top surface of the lifting plate, the placement rack including a support plate, vertical shafts being mounted at the four corners of the bottom surface of the support plate, and positioning holes being provided at the four corners of the top surface of the support plate that mate with the vertical shafts.

[0007] Furthermore, a servo motor is installed inside the chassis, and a second bevel gear is driven to the output end of the servo motor. One end of the second bevel gear extends to the outside of the chassis, and a first bevel gear is fitted to one end of the lead screw. The first bevel gear and the second bevel gear mesh with each other.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the servo motor drives the second bevel gear to rotate, and through the meshing of the first bevel gear and the second bevel gear, the power is transmitted to the lead screw, thereby realizing the rotation of the lead screw and thus accurately adjusting the height of the lifting plate.

[0009] Furthermore, the placement rack includes a tray, the vertical shaft includes a sleeve and a rod, the inside of the sleeve is slidably connected to one end of the rod, a damping rod is installed at the top of the inside of the sleeve, the bottom end of the damping rod is connected to the top end of the rod, and a spring is sleeved on the outer wall of the damping rod.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the length of the vertical shaft can be adjusted by the interlocking sliding between the sleeve and the rod. Combined with the buffering effect of the damping rod and the spring, the downward pressure on the vertical shaft can be buffered, thereby reducing the impact damage caused by the car bumper workpieces stacked on the top surface of the pallet.

[0011] Furthermore, a gasket is adhered to the top surface of the tray.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it can play a buffering and protective role when placing the car bumper, avoiding scratches or wear caused by direct contact between the bumper surface and the support plate, and improving the surface quality of the bumper.

[0013] Furthermore, casters are installed at the four corners of the bottom surface of the chassis.

[0014] The beneficial effects of adopting the above-mentioned further solutions are that the vehicle can be easily moved within the workshop, facilitating the transport of car bumpers, reducing handling difficulties, improving transportation efficiency, and adapting to the transfer needs between different work areas within the workshop.

[0015] Furthermore, a handrail is installed on the outer wall of the storage frame.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it provides a gripping point for the operator, who can better control the direction and force of the vehicle's movement by using the handrail when pushing the vehicle.

[0017] Furthermore, the chassis includes a housing, on the inner side of the housing away from the servo motor, a counterweight is placed.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the counterweight can balance the weight imbalance caused by components such as servo motors, making the vehicle more stable during placement and movement, and preventing the vehicle from tipping over due to the shift of the center of gravity.

[0019] Furthermore, the top surface of the storage frame is provided with a dispensing port.

[0020] The advantage of adopting the above-mentioned further solution is that it makes it convenient for operators to place the car bumper directly into the storage rack in the storage box, or to take the bumper out of the storage rack, without having to open other parts. The operation is simple and quick, improving work efficiency.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This type of car bumper processing workshop transport and storage carrier, through the cooperation of a lifting mechanism and a placement rack, facilitates the stacking and retrieval of car bumpers. Specifically, by rotating a lead screw and through its threaded connection with the lifting plate, the lifting plate can slide up and down within the storage frame, thereby adjusting the height of the placement rack. This allows the placement rack supporting the car bumper to move downwards, providing space for the next car bumper. This flexibly changes the storage space layout within the storage frame until the stacking requirements of the storage carrier are met. Furthermore, the telescopic buffering characteristics of the vertical shaft reduce impact damage to car bumper workpieces stacked on the top surface of the pallet. Conversely, by controlling the lifting plate to raise the height and sequentially removing the placement rack, it is convenient to retrieve car bumpers from the drop-out port of the storage frame.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6This utility model provides a technical solution: a transport and storage vehicle for an automobile bumper processing workshop, including a storage frame 100, with a housing 200 installed at the bottom of the storage frame 100; a lifting mechanism 400, which is located on one side of the storage frame 100 and the housing 200, the lifting mechanism 400 including a top plate 4001 and a bottom plate 4002, the top plate 4001 being installed on the outer wall of the storage frame 100, and the bottom plate 4002 being installed on the outer wall of the housing 200, a lead screw 4004 rotatably connecting the top plate 4001 and the bottom plate 4002. One end of the storage frame 100 is threadedly connected to a lifting plate 4003. A slotted groove is provided on one side of the storage frame 100 to engage with one side of the lifting plate 4003. The lifting plate 4003 is slidably connected inside the storage frame 100. A placement rack 300 is stacked on the top surface of the lifting plate 4003. By causing the lead screw 4004 to rotate, and in conjunction with the threaded connection between the lead screw 4004 and the lifting plate 4003, the lifting plate 4003 can slide up and down within the storage frame 100, thereby adjusting the height of the placement rack 300, allowing the placement rack 300 supporting the car bumper to move downwards. The storage space within the storage frame 100 can be moved to make room for the next car bumper, allowing for flexible adjustments to the storage layout until the stacking requirements of the storage container are met. Conversely, the height can be increased by controlling the lifting plate 4003, and the placement rack 300 can be removed sequentially to facilitate the removal of the car bumper from the delivery port of the storage frame 100. The placement rack 300 is placed on the top surface of the lifting plate 4003. The placement rack 300 includes a support plate 3001, with vertical shafts 3002 installed at the four corners of the bottom surface of the support plate 3001, and vertical shafts 3002 installed at the four corners of the top surface of the support plate 3001. The vertical shaft 3002 is provided with positioning holes 3004 that match the vertical shaft 3002. The vertical shaft 3002 can be inserted into the positioning holes 3004 at the four corners of the top surface of the lower tray 3001, so that the placement rack can be accurately aligned when stacked, ensuring the stability of the stacking, preventing misalignment between the placement racks, and ensuring the safety of the bumper during storage and transportation. The top surface of the tray 3001 is attached with a gasket 3003, which can play a buffering and protective role when placing the car bumper, avoiding direct contact between the bumper surface and the tray 3001 to prevent scratches or wear, and improving the surface quality of the bumper.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] As an embodiment of this utility model, a servo motor 900 is further installed inside the chassis 200. The output end of the servo motor 900 is connected to a second bevel gear 800. One end of the second bevel gear 800 extends to the outside of the chassis 200. One end of the lead screw 4004 is fitted with a first bevel gear 700. The first bevel gear 700 and the second bevel gear 800 mesh with each other. The servo motor 900 drives the second bevel gear 800 to rotate. Through the meshing of the first bevel gear 700 and the second bevel gear 800, power is transmitted to the lead screw 4004, realizing the rotation of the lead screw 4004, thereby precisely adjusting the height of the lifting plate 4003.

[0034] As an embodiment of this utility model, the vertical shaft 3002 further includes a sleeve 30021 and a rod 30022. The interior of the sleeve 30021 is slidably connected to one end of the rod 30022. A damping rod 30023 is installed at the top end of the interior of the sleeve 30021. The bottom end of the damping rod 30023 is connected to the top end of the rod 30022. A spring 30024 is sleeved on the outer wall of the damping rod 30023. Through the interlocking sliding between the sleeve 30021 and the rod 30022, the length of the vertical shaft 3002 can be adjusted. Combined with the buffering effect of the damping rod 30023 and the spring 30024, the downward pressure on the vertical shaft 3002 can be buffered, thereby reducing the impact damage caused by the car bumper workpiece stacked on the top surface of the pallet 3001.

[0035] As an embodiment of this utility model, furthermore, pulleys 500 are installed at the four corners of the bottom surface of the chassis 200, so that the vehicle can move easily in the workshop, which facilitates the transportation of car bumpers, reduces the difficulty of handling, improves transportation efficiency, and adapts to the transfer needs between different work areas in the workshop. Handrails 600 are installed on the outer wall of the storage box 100, providing a gripping point for the operator. When pushing the vehicle to move, the operator can better control the direction and force of the vehicle's movement through the handrails 600.

[0036] As an embodiment of this utility model, the chassis 200 further includes a housing 2001. A counterweight 2002 is placed on the inner side of the housing 2001 away from the servo motor 900. The counterweight 2002 can balance the weight imbalance caused by the servo motor 900 and other components, making the vehicle more stable during placement and movement, and preventing the vehicle from tipping over due to the shift of the center of gravity.

[0037] As an embodiment of this utility model, the top surface of the storage box 100 is provided with a placement port, which makes it convenient for operators to directly place the car bumper into the placement rack 300 inside the storage box 100, or to take the bumper out from the placement rack 300, without having to open other parts. The operation is simple and quick, improving work efficiency.

[0038] Specifically, the working principle of this car bumper processing workshop transport and storage carrier is as follows: During use, in the storage stage, when a car bumper needs to be stored, the servo motor 900 inside the housing 200 is started. Its output end drives the second bevel gear 800 to rotate. The second bevel gear 800 meshes with the first bevel gear 700 fitted at one end of the lead screw 4004, transmitting power to the lead screw 4004 to make it rotate. When the lead screw 4004 rotates, through the threaded connection with the lifting plate 4003, the lifting plate 4003 slides downward along the hollow groove in the storage frame 100, thereby lowering the height of the placement rack 300 and making room for the next car bumper. The placement rack 300 is composed of a tray 3001. The vertical shafts 3002 at the four corners of the bottom surface can be precisely inserted into the positioning holes 3004 at the four corners of the top surface of the lower tray 3001 to ensure stacking stability. The gaskets 3003 attached to the top surface of the tray 3001 can prevent scratches on the surface of the bumper. Operators can place the bumper onto the placement rack 300 through the drop-out port on the top of the storage frame 100, repeating the above steps until the stacking requirements are met. During transportation, the casters 500 at the four corners of the chassis 200 facilitate movement of the vehicle within the workshop. Operators can flexibly control the direction and force of the vehicle's movement by holding the handles 600 on the outer wall of the storage frame 100. A counterweight 2002 placed inside the chassis 200 away from the servo motor 900 balances the weight imbalance caused by the servo motor and other components, ensuring stability during vehicle movement and placement. During retrieval, the servo motor 900 is restarted to reverse the rotation of the lead screw 4004, causing the lifting plate 4003 to rise. Operators then remove the placement rack 300 sequentially and conveniently retrieve the car bumper through the drop-out port on the top of the storage frame 100.
