Description

Technical Field

[0001] This utility model relates to the field of automotive reinforcing plate conveying technology, and in particular to a conveying device. Background Technology

[0002] Existing conveyor trolleys generally consist of a base plate, wheels, and handrails. When in use, metal plates can be placed directly on the upper surface of the base plate for transportation. The structure is simple and the cost of use is low. However, the sides generally lack protection. When small metal plates are placed high, they are not easy to fix and are prone to tipping over. At the same time, when transporting large metal plates, the lack of support around the large metal plates can cause them to deform during transportation, resulting in poor performance.

[0003] Utility model patent CN217124890U discloses a metal plate conveying trolley, including a base plate and positioning units. Wheels are provided at the four corners of the lower surface of the base plate, and a handrail is provided at the front end of the base plate. Rotary shafts are rotatably connected inside the rotating holes at both ends of the base plate. The ends of two longitudinally corresponding rotating shafts are fixedly connected to the same side plate, and a side support frame is fixedly connected to the upper end of each side plate. Positioning units are respectively disposed inside the side support frames, and the lower ends of the positioning units are fitted into the base plate. When transporting small metal plates, the metal plates can be neatly stacked on the upper surface of the first rubber guard plate. Simultaneously, the second rubber guard plate, under the action of the side support frame, can provide lateral positioning for the metal plates, thereby preventing tipping and scattering. When transporting large metal plates, the side support frames can be unfolded, thereby providing good support for the large metal plates and preventing deformation.

[0004] In the above scheme, when transporting large metal plates, the side support frame is laid flat. When the side support frame is in a flat state, the upper surface of the second rubber guard plate is flush with the upper surface of the first rubber guard plate. Then, the large metal plate can be placed on the upper surfaces of the second and first rubber guard plates to facilitate the transport of the large metal plate. However, after unfolding the side support frame, although the side support frame can support the large metal plate, the sides of the large metal plate lack protection and are prone to slipping. Utility Model Content

[0005] The purpose of this invention is to provide a conveying device that can support and protect large metal plates to prevent them from slipping.

[0006] To achieve the above objectives, this utility model provides a conveying device, including a base plate with wheels at its bottom and a protective assembly; the protective assembly includes multiple first support plates, multiple second support plates, a first connecting plate, a second connecting plate, two side protective frames, and multiple side protective brackets. Multiple placement slots are spaced apart on the upper surface of the base plate, the width of each placement slot being the sum of the widths of the first and second support plates. Multiple first support plates are slidably connected to the base plate, and multiple second support plates are slidably connected to the base plate. Each placement slot contains one first support plate and one second support plate. Multiple first support plates are fixedly connected to the first connecting plate, and multiple second support plates are fixedly connected to the second connecting plate. The first and second connecting plates are located on opposite sides of the base plate. Two side protective frames are fixedly installed above the first and second connecting plates, and multiple side protective brackets are spaced apart on the inner side of each side protective frame.

[0007] The side protection frame includes a fixed frame, a spring, and two movable frames. The two movable frames are slidably connected to the fixed frame and are located at both ends of the fixed frame. The two ends of the spring are fixedly connected to the two movable frames and are located inside the fixed frame.

[0008] The side protection frame also includes two connecting seats. Each of the two movable frames is rotatably provided with a connecting seat at the end away from the fixed frame. The connecting seats are threadedly connected to the side protection frame.

[0009] The protective assembly further includes a fixing structure, which includes an adjusting screw and a fixing cylinder. One end of the fixing cylinder is fixedly connected to the base plate, and one end of the adjusting screw is threadedly connected to the fixing cylinder. The adjusting screw is located inside the fixing cylinder, and the other end of the adjusting screw extends out of the fixing cylinder and is rotatably connected to the first connecting plate.

[0010] The fixing structure further includes a rotating block, which is fixedly connected to the adjusting screw and is located at the end of the adjusting screw away from the fixing cylinder.

[0011] This utility model discloses a conveying device. When conveying smaller automotive reinforcing plates, multiple side guards can be installed inside the side guard frame to reduce the distance between adjacent side guards, thus protecting the sides of the smaller automotive reinforcing plates and preventing them from tipping over and scattering. When conveying larger automotive reinforcing plates, the first connecting plate and the second connecting plate can be pulled to pull the first support plate and the second support plate out of the placement groove, thereby increasing the distance between the two side guard frames. This allows the larger automotive reinforcing plates to be placed on the base plate, and the first support plate and the second support plate can support the automotive reinforcing plates. The side guards can protect the sides of the automotive reinforcing plates, thus preventing the larger automotive reinforcing plates from falling off the base plate. Attached Figure Description

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1 to 3 , Figure 1 This is a structural schematic diagram of a conveying device according to this utility model. Figure 2 This is a transverse structural sectional view of the base plate of a conveying device according to this utility model. Figure 3This is a structural cross-sectional view of the inner side of the side protection frame of a conveying device according to this utility model.

[0019] This utility model provides a conveying device, including a base plate 100 with wheels at the bottom and a protective assembly. The protective assembly includes multiple first support plates 210, multiple second support plates 220, a first connecting plate 230, a second connecting plate 240, two side protective frames 250, multiple side protective brackets, and a fixing structure. The side protective brackets include a fixing bracket 261, a spring 262, two movable brackets 263, and two connecting seats 264. The fixing structure includes an adjusting screw 271, a fixing cylinder 272, and a rotating block 273.

[0020] In this specific embodiment, the upper surface of the base plate 100 is provided with a plurality of placement slots 110 at intervals. The width of each placement slot 110 is the sum of the widths of the first support plate 210 and the second support plate 220. The plurality of first support plates 210 are slidably connected to the base plate 100, and the plurality of second support plates 220 are slidably connected to the base plate 100. Each placement slot 110 contains one first support plate 210 and one second support plate 220. The plurality of first support plates 210 are fixedly connected to the first connecting plate 230, and the plurality of second support plates 220 are fixedly connected to the second connecting plate 240. The first connecting plate 230 and the second connecting plate 240 are located on both sides of the base plate 100. Two side protective frames 250 are fixedly installed above the first connecting plate 230 and the second connecting plate 240, respectively. The inner side of each side protective frame 250 is provided with a plurality of side protective brackets at intervals. The upper surfaces of the first support plate 210, the second support plate 220, and the base plate 100 are flush. The first support plate 210 and the second support plate 220 can slide inside the placement groove 110. The first connecting plate 230 is used to connect each of the first support plates 210, and the second connecting plate 240 is used to connect each of the second support plates 220. The two side protection frames 250 are respectively disposed above the first connecting plate 230 and the second connecting plate 240. Multiple side protection brackets are spaced apart inside the side protection frame 250. The side protection brackets can be detached from the side protection frame 250 to adjust the spacing between two adjacent side protection brackets, thereby matching vehicle reinforcement plates of different sizes. When transporting smaller automotive reinforcement plates, multiple side guards can be installed on the inner side of the side guard frame to reduce the distance between adjacent side guards, thus shielding and protecting the sides of the smaller automotive reinforcement plates to prevent them from tipping over and scattering. When transporting larger automotive reinforcement plates, the first connecting plate 230 and the second connecting plate 240 can be pulled to pull the first support plate 210 and the second support plate 220 out of the placement slot 110, thereby increasing the distance between the two side guard frames 250. This allows for the placement of larger automotive reinforcement plates on the base plate 100, and the first support plate 210 and the second support plate 220 can support the automotive reinforcement plates. The side guards can protect the sides of the automotive reinforcement plates, thus preventing larger automotive reinforcement plates from falling off the base plate 100.

[0021] Furthermore, the two movable frames 263 are slidably connected to the fixed frame 261, and the two movable frames 263 are located at both ends of the fixed frame 261. The two ends of the spring 262 are fixedly connected to the two movable frames 263, and the spring 262 is located inside the fixed frame 261. The two ends of the spring 262 abut against the two movable frames 263 to hold the two movable frames 263 against the inner side of the side protective frame 250, thereby fixing the side protective frame to the inner side of the side protective frame 250 to protect the vehicle reinforcement plate.

[0022] Specifically, each of the two movable frames 263 has a connecting seat 264 rotatably mounted at the end away from the fixed frame 261, and the connecting seat 264 is threadedly connected to the side protective frame 250. The end of the connecting seat 264 away from the movable frame 263 has a threaded post, and the inner side of the side protective frame 250 has multiple threaded grooves spaced apart. By screwing the threaded post of the connecting seat 264 into the threaded grooves, the side protective frame can be fixed to the inner side of the side protective frame 250.

[0023] One end of the fixed cylinder 272 is fixedly connected to the base plate 100, and one end of the adjusting screw 271 is threadedly connected to the fixed cylinder 272. The adjusting screw 271 is located inside the fixed cylinder 272, and the other end of the adjusting screw 271 extends out of the fixed cylinder 272 and is rotatably connected to the first connecting plate 230. The fixing structure is used to fix the first support plate 210 to the base plate 100. The adjusting screw 271 can rotate relative to the fixed cylinder 272. When the adjusting screw 271 rotates, the length of the adjusting screw 271 in the fixed cylinder 272 changes, thereby allowing the adjusting screw 271 to move out of the fixed cylinder 272. When the adjusting screw 271 moves, it drives the first connecting plate 230 to move together, so that the first support plate 210 moves with the first connecting plate 230, thereby adjusting the position of the first support plate 210, so that the first support plate 210 can be moved out of the placement groove 110. Similarly, the same fixing structure can be used to adjust the position of the second support plate 220, thereby adjusting the distance between the two side protection frames 250 to match vehicle reinforcement plates of different sizes.

[0024] Furthermore, the rotating block 273 is fixedly connected to the adjusting screw 271, and the rotating block 273 is located at the end of the adjusting screw 271 away from the fixed cylinder 272. The rotating block 273 is provided at the end of the adjusting screw 271, and the adjusting screw 271 can be rotated by the rotating block 273 to facilitate the rotation of the adjusting screw 271.

[0025] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
