Description

Technical Field

[0001] This application relates to the field of material handling equipment, and in particular to a material handling trolley. Background Technology

[0002] As a type of lightweight material handling equipment, the material handling trolley can effectively reduce the labor intensity of manual material handling and improve the efficiency of short-distance material transfer. It is an indispensable auxiliary tool for transferring industrial products such as parts and finished goods.

[0003] In related technologies, the bucket structure of material transport trolleys is mostly a fixed closed or open design. Fixed closed buckets typically consist of a bottom plate and side plates fixedly connected around the perimeter, with only a feeding opening at the top. While this structure can prevent materials from spilling during transportation, when materials need to be unloaded, they tend to accumulate in the corners of the bucket, resulting in incomplete unloading, requiring workers to remove the remaining materials. Open buckets, on the other hand, generally only have a bottom plate and fixed side plates on both sides, with no obstructions at the front and rear. Although this makes loading and unloading materials convenient, during transportation, materials are prone to falling out of the bucket due to road bumps or turning operations, causing material damage and potentially posing safety hazards to surrounding personnel and equipment.

[0004] Regarding the aforementioned technologies, the inventors believe that the material transport trolley has difficulty balancing "transport protection" and "convenience of unloading," and there is still room for improvement. Utility Model Content

[0005] In order to improve the problem that material transport trolleys cannot simultaneously achieve "transport protection" and "convenience of unloading", this application provides a material transport trolley.

[0006] The material transport handcart provided in this application adopts the following technical solution: A material handling trolley includes a frame and a bucket fixedly connected to the frame. The bucket includes a bottom plate, two side plates fixedly connected to the bottom plate and arranged opposite to each other, an end plate fixedly connected to the bottom plate and connecting one end of the two side plates on the same side, a movable plate hinged to the side of the bottom plate away from the end plate to cooperate with the side plates and the end plate to enclose the bottom plate, and a locking assembly disposed on the side plate to lock the movable plate and the side plates.

[0007] By adopting the above technical solution, when transporting materials, the movable plate is locked to the side plate by the locking component. The movable plate can work with the side plate, end plate and bottom plate to form an opening for receiving materials. This can effectively prevent the materials from shaking due to road bumps or turning operations, and prevent the materials from falling out of the truck bed, thus improving the stability of material transportation. When unloading is required, the movable plate can be rotated to open the truck bed opening by unlocking the locking component. At this time, the materials can be discharged directly from the open side of the movable plate without the need for workers to go deep into the truck bed to clean the corner residues, thus improving the convenience of unloading.

[0008] Optionally, the movable plate includes an enclosure portion hinged to the base plate and two limiting portions fixedly connected to both sides of the enclosure portion.

[0009] By adopting the above technical solution, when the movable plate is unlocked and opened, the enclosure part rotates and unfolds with the limiting part to form an inclined "discharge slide plate". The material can slide down along the surface of the enclosure part. The two limiting parts form "edges" on both sides of the enclosure part, which effectively prevents the material from falling from the side edges of the truck bed, avoids damage caused by material leakage, and reduces material loss during unloading.

[0010] Optionally, the locking assembly includes a rotating rod hinged to the side plate and a locking rod fixedly connected to the rotating rod and disposed perpendicular to the rotating rod, and a locking block for the locking rod to hook onto is fixedly connected to the limiting part.

[0011] By adopting the above technical solution, the locking rod and the rotating rod are set vertically, and together with the hook structure of the locking block, an "L"-shaped engagement is formed, which can effectively resist the outward squeezing force of the material on the moving plate and improve the stability of the locking structure of the moving plate and the side plate.

[0012] Optionally, an extension plate is fixedly connected to the side of the enclosure near the base plate. When the enclosure is rotated to the open state, the extension plate abuts against the bottom of the base plate.

[0013] By adopting the above technical solution, when the enclosure is opened for unloading, the extension plate abuts against the bottom of the base plate to form a stable support, which can fix the enclosure at the optimal unloading angle, ensuring that the material slides smoothly along the enclosure, thus improving the convenience and stability of unloading.

[0014] Optionally, the locking assembly includes two connecting rods that are rotatably connected to the two side plates respectively, and the two connecting rods are slidably connected to the side plates along the thickness direction of the side plates. A locking post is fixedly connected to the connecting rod and is perpendicular to the side plate. The limiting part is provided with a first locking hole for the locking post to pass through. When the locking post passes through the first locking hole, the enclosing part is locked in the enclosing state.

[0015] By adopting the above technical solution, the locking post is perpendicular to the side plate and passes through the first locking hole of the limiting part, forming a "through-shaft" locking structure, which avoids the locking loosening caused by the displacement of the movable plate due to force, enhances the material protection effect during transportation, and reduces the risk of material falling.

[0016] Optionally, the limiting part is provided with a second locking hole for the locking post to pass through. When the locking post passes through the second locking hole, the enclosing part reaches the maximum rotation angle.

[0017] By adopting the above technical solution, when the locking pin is inserted into the second locking hole, the movable plate reaches the maximum rotation angle (optimal feeding angle), which avoids the material from falling too fast due to excessive rotation angle of the movable plate, resulting in material accumulation and collision damage, and reduces material loss.

[0018] Optionally, the base plate includes a base plate body and an inclined portion integrally connected to one end of the base plate body near the movable plate, wherein the inclined portion is inclined downward from the side near the base plate body to the side away from the base plate body.

[0019] By adopting the above technical solution, the tilt angle of the inclined part can be used to accelerate material unloading with the help of gravity, thereby improving operation efficiency.

[0020] Optionally, a plurality of parallel rollers are rotatably connected to the base plate body, and the plurality of rollers are distributed from the side closer to the movable plate to the side farther away from the movable plate.

[0021] By adopting the above technical solution, the rolling characteristics of the roller can reduce the resistance to material movement, making it easier for workers to push the material to adjust its position when loading, thus improving the convenience of material adjustment; when unloading, the material slides along the inclined part of the roller, which can reduce friction and scratches between the material and the base plate, protect the material surface, and reduce material loss.

[0022] Optionally, the base plate further includes a discharge section located on the side of the inclined portion away from the main body of the base plate. The width of the discharge section is smaller than the width of the main body of the base plate, and the width of the inclined portion gradually decreases from the side closer to the main body of the base plate to the side farther away from the main body of the base plate.

[0023] By adopting the above technical solution, the design of "gradually narrowing" width of the inclined part, combined with the restriction of the side plate, can form a "guide channel" that converges towards the unloading part, guiding the material to naturally concentrate towards the unloading part and improving the material concentration during unloading.

[0024] Optionally, a protective strip is fixedly connected to the side of the side plate away from the bottom plate.

[0025] By adopting the above technical solution, the protective strip can reduce the probability of workers being scratched by the metal edge of the side plate when loading and unloading materials, thus improving the safety of workers when loading and unloading materials.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The movable plate can be used with the side plates, end plates and bottom plate to form an open-top receiving space, which effectively prevents materials from falling out of the truck bed and improves the stability of material transportation; when unloading, the materials can be directly discharged from the truck bed by rotating the movable plate to open one side, which improves the convenience of unloading. 2. When the movable plate is opened, the enclosure expands with the rotation of the limiting part to form an inclined "discharge slide". The material can slide down along the surface of the enclosure. At the same time, the limiting part forms "edges" on both sides of the enclosure, which effectively prevents the material from falling from the side edges of the truck bed and reduces material loss during unloading. 3. When the enclosure is opened for unloading, the extension plate abuts against the bottom of the base plate to form a stable support, fixing the enclosure at the optimal unloading angle, ensuring that the material slides smoothly along the enclosure, and improving the convenience and stability of unloading.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] Example 1: Embodiment 1 of this application discloses a material transport trolley. (Refer to...) Figure 1 The material handling trolley includes a frame 1 and a bucket 2, with the bucket 2 fixedly connected to the frame 1 for loading materials.

[0034] Reference Figure 1 and Figure 2The truck bed 2 includes a bottom plate 21, side plates 22, end plates 23, movable plates 24, and locking components 25. The bottom plate 21 includes a bottom plate body 211, an inclined portion 212, and a discharge portion 213. The bottom plate body 211 is fixedly connected to the frame 1. The inclined portion 212 is integrally connected to the bottom plate body 211, and the height of the inclined portion 212 gradually decreases from the side closest to the bottom plate body 211 to the side furthest from the bottom plate body 211, while the width of the inclined portion 212 gradually narrows from the side closest to the bottom plate body 211 to the side furthest from the bottom plate body 211. The discharge portion 213 is integrally connected to the side of the inclined portion 212 furthest from the bottom plate body 211 for precise material discharge. To facilitate workers in adjusting the position of materials on the base plate 211, several parallel rollers 2111 are rotatably connected to the base plate 211. The rollers 2111 are arranged sequentially from the side closest to the inclined part 212 to the side furthest from the inclined part 212, so that workers can push materials closer to or away from the unloading part 213.

[0035] Reference Figure 1 and Figure 2 There are two side plates 22, which are fixedly connected to opposite sides of the base plate 21 and respectively fit against the edges of the base plate main body 211, the inclined part 212, and the unloading part 213 to prevent materials from falling from the sides of the trolley. To prevent the metal edges of the side plates 22 from scratching workers, a protective strip 221 is fixedly connected to the side of the side plate 22 away from the base plate main body 211. The end plate 23 is fixedly connected to the side of the base plate main body 211 away from the inclined part 212 and connects the two side plates 22.

[0036] Reference Figure 1 and Figure 3 The movable plate 24 includes an enclosing portion 241 and two limiting portions 242. The enclosing portion 241 is hinged to the side of the base plate 21 away from the end plate 23 to cooperate with the side plate 22 and the end plate 23 to enclose the base plate 21. The limiting portions 242 are fixedly connected to the two sides of the enclosing portion 241 near the side plate 22 and are located on the opposite side of the side plate 22. The locking assembly 25 includes a rotating rod 251 and a locking rod 252. The rotating rod 251 is rotatably connected to the side plate 22. The locking rod 252 is fixedly connected to the side of the rotating rod 251 away from the side plate 22 and is arranged perpendicular to the rotating rod 251. A locking block 2421 is fixedly connected to the limiting part 242. When the rotating rod 251 is rotated so that it passes through the gap between the locking block 2421 and the limiting part 242, the locking rod 252 is located on the side of the locking block 2421 away from the end plate 23. When the enclosing part 241 is impacted by the material and rotates to the side away from the end plate 23, the locking rod 252 abuts against the locking block 2421 to limit the rotation of the enclosing part 241.

[0037] Reference Figure 1In order to limit the maximum rotation angle of the enclosure 241, an extension plate 2411 is fixedly connected to the side of the enclosure 241 near the base plate 21. When the enclosure 241 is rotated to the open state, the extension plate 2411 abuts against the bottom of the base plate 21 to position the enclosure 241 at the optimal feeding angle.

[0038] The implementation principle of Example 1 is as follows: When the rotating rod 251 is rotated to the gap between the limiting part 242 and the locking block 2421, the locking rod 252 cooperates with the locking block 2421 to lock the movable plate 24. The end plate 23, the movable plate 24 and the two side plates 22 surround the bottom plate 21, and the material can be transferred and conveyed at this time. Rotate the rotating rod 251 out of the gap between the limiting part 242 and the locking block 2421, and the movable plate 24 is unlocked. Rotate the movable plate 24 until the extension plate 2411 abuts against the bottom of the unloading part 213. At this time, the worker can push the material along the rolling direction of the roller 2111 to the inclined part 212, and unload the material from the hopper 2 at the unloading part 213.

[0039] Example 2: Reference Figure 4 The difference between Embodiment 2 and Embodiment 1 is that the locking assembly 25 includes two connecting rods 253. The side plate 22 has mounting holes 222. One end of each connecting rod 253 is fixedly connected to a mounting post 2531, which passes through the mounting hole 222, allowing the two connecting rods 253 to be rotatably connected to the side plate 22 and slide along the thickness direction of the side plate 22. A limit block 2532 is fixedly connected to the end of the mounting post 2531 away from the connecting rod 253 to prevent the connecting rod 253 from detaching from the side plate 22 when sliding along its thickness. A locking post 2533 is fixedly connected to the end of the connecting rod 253 away from the mounting post 2531, and the locking post 2533 is arranged perpendicular to the connecting rod 253. The limiting part 242 has a first locking hole 2422 and a second locking hole 2423. The locking pin 2533 passes through the first locking hole 2422 or the second locking hole 2423 to realize the enclosure or opening of the movable plate 24.

[0040] The implementation principle of Example 2 is as follows: when the locking pin 2533 is inserted into the first locking hole 2422, the movable plate 24 is locked, and the end plate 23, the movable plate 24 and the two side plates 22 surround the bottom plate 21, at which time the material can be transferred and conveyed. Push the connecting rod 253 away from the limit block 2532 to disengage the locking pin 2533 from the first locking hole 2422. Then rotate the movable plate 24 and the connecting rod 253. When the locking pin 2533 is aligned with the second locking hole 2423, push the connecting rod 253 to make the locking pin 2533 pass through the second locking hole 2423. At this time, the movable plate 24 rotates to the optimal feeding angle. The worker can push the material along the rolling direction of the roller 2111 to the inclined part 212 and unload the material from the hopper 2 at the unloading part 213.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
