Description

Technical Field

[0001] This utility model relates to the field of building material transportation technology, and in particular to a transportation device for construction sites. Background Technology

[0002] In the construction industry, handcarts are a common tool for short-distance material transfer. Traditional handcart unloading methods usually rely on operators lifting the rear of the cart to tilt it, and then using gravity to dump the items inside, especially bulk or small building materials such as sand, bricks, and cement bags.

[0003] However, when a transport vehicle is fully loaded, the building materials piled inside often have a high density and volume, resulting in a significant increase in the overall weight of the vehicle. Operators must expend tremendous physical strength to manually flip or tilt such a heavily loaded vehicle to a sufficient angle for tipping, a process that is extremely laborious and time-consuming. Furthermore, the vehicle's support to the ground often relies on its wheels, posing a safety risk. Utility Model Content

[0004] The main purpose of this utility model is to propose a transportation device for construction sites, which aims to improve unloading efficiency.

[0005] To achieve the above objectives, the present invention provides a construction site transportation device comprising:

[0006] The vehicle body includes an integrally connected bottom plate, side plates, and rear plate. The bottom plate is rotatably connected to a front plate. The bottom plate, the rear plate, the side plates, and the front plate together form a transport trough.

[0007] The side plate is rotatably connected to a locking hook, which corresponds to a locking protrusion on the front plate to restrict the front plate from flipping outward.

[0008] The unloading assembly includes multiple unloading plates. A roller is rotatably connected to the bottom of the transport trough. The unloading plates abut against the side wall of the roller away from the bottom plate. Adjacent unloading plates are hinged together by a hinge, and the hinge is located on the side of the unloading plate near the bottom plate.

[0009] Among them, the unloading plate near the rear plate is fixedly connected to a push plate, which is adapted to the rear plate. After the front plate flips outward, it can push the material in the transport trough to the side of the front plate.

[0010] In one embodiment, the two ends of the roller are rotatably connected to the side plate, and there are multiple rollers, which are spaced apart at the bottom of the transport trough along the length of the base plate.

[0011] In one embodiment, the sidewall is provided with a guide strip located on the side of the unloading plate away from the bottom plate to prevent the unloading plate from tipping over in the transport trough.

[0012] In one embodiment, the roller sidewall is recessed to form an annular clearance groove, which is correspondingly provided with the hinge member to avoid the hinge member.

[0013] In one embodiment, the unloading plate has a recessed mounting groove on one side near the base plate, the mounting groove being adapted to the hinge, and the hinge being disposed within the mounting groove.

[0014] In one embodiment, a limiting strip is provided on the side of the front plate away from the bottom plate, and the limiting strip abuts against the side wall to limit the inward rotation angle of the front plate.

[0015] In one embodiment, the limiting strip is provided with the locking boss, which is adapted to the hook head of the locking hook. When the locking hook is rotated, the hook head abuts against the locking boss to restrict the front plate from flipping outward.

[0016] In one embodiment, the locking hook has a socket, and the side plate has a through hole corresponding to the socket for inserting a pin. The pin passes through the socket and the through hole to restrict the locking hook from rotating relative to the side plate.

[0017] In one embodiment, the pusher plate has a handle on the side away from the unloading plate.

[0018] In one embodiment, a reinforcing rib is provided between the push plate and the adjacent unloading plate.

[0019] The technical solution of this utility model involves flipping the front plate outward to form a discharge outlet. Then, by pushing the push plate, the material placed on the discharge plate can be pushed out from the outlet on the front plate side. The discharge plate slides on the roller, reducing friction, allowing the operator to push the material out with only a certain amount of force. Multiple discharge plates slide out sequentially, and the slid-out discharge plates flip downward due to gravity, preventing material from remaining on them. This completes the unloading process and avoids lever action that could cause the vehicle body to tilt. Furthermore, the cooperation of the locking hook and the locking boss prevents the front plate from flipping outward during transportation, ensuring unloading safety, reducing labor intensity and physical exertion, and improving unloading efficiency.

[0033] In the construction industry, handcarts are a common tool for short-distance material transfer. Traditional handcart unloading methods usually rely on operators lifting the rear of the cart to tilt it, and then using gravity to dump the items inside, especially bulk or small building materials such as sand, bricks, and cement bags.

[0034] However, when a transport vehicle is fully loaded, the building materials piled inside often have a high density and volume, resulting in a significant increase in the overall weight of the vehicle. Operators must expend tremendous physical strength to manually flip or tilt such a heavily loaded vehicle to a sufficient angle for tipping, a process that is extremely laborious and time-consuming. Furthermore, the vehicle's support to the ground often relies on its wheels, posing a safety risk.

[0035] This utility model proposes a transportation device for construction sites.

[0036] Please see Figures 1 to 6 In one embodiment of this utility model, the construction site transportation device includes:

[0037] The vehicle body 1 includes an integrally connected bottom plate 11, side plates 12 and rear plate 13. The bottom plate 11 is rotatably connected to a front plate 14. The bottom plate 11, rear plate 13, side plates 12 and front plate 14 together form a transport trough 2.

[0038] The side plate 12 is rotatably connected to a locking hook 3, which corresponds to the locking protrusion 141 provided on the front plate 14 to restrict the front plate 14 from flipping outward.

[0039] The unloading assembly includes multiple unloading plates 41. A roller 42 is rotatably connected to the bottom of the transport trough 2. The unloading plates 41 abut against the side wall of the roller 42 away from the bottom plate 11. Adjacent unloading plates 41 are hinged together by a hinge 43, and the hinge 43 is provided on the side of the unloading plate 41 close to the bottom plate 11.

[0040] Among them, the unloading plate 41 near the rear plate 13 is fixedly connected to the push plate 44, the push plate 44 is adapted to the rear plate 13, and after the front plate 14 is flipped outward, it can push the material in the transport trough 2 to move towards the front plate 14.

[0041] The technical solution of this utility model is to form a discharge outlet by flipping the front plate 14 outward. Then, by pushing the push plate 44, the material placed on the discharge plate 41 can be pushed out from the outlet on the side of the front plate 14. The discharge plate 41 slides on the roller 42, reducing friction. This allows the operator to push out the material with only a certain amount of force. Multiple discharge plates 41 will slide out in sequence, and the discharged discharge plates 41 will flip downward due to gravity, preventing the material from remaining on the discharge plates 41. This completes the unloading and avoids the tilting of the vehicle body 1 caused by leverage. Furthermore, the cooperation between the locking hook 3 and the locking boss 141 can prevent the front plate 14 from flipping outward during transportation, ensuring unloading safety, reducing labor intensity and physical consumption, and improving unloading efficiency.

[0042] For ease of understanding, the side of the transport trough 2 closest to the bottom plate 11 is defined as downward, and the side closest to the front plate 14 is defined as forward.

[0043] like Figure 1 As shown, the bottom plate 11, the rear plate 13, the side plate 12 and the front plate 14 together form the transport trough 2. When the front plate 14 is flipped outward, the side of the transport trough 2 near the front plate 14 will lose its obstruction and form a discharge port, through which the material can be discharged directly.

[0044] In some implementations, such as Figure 1 As shown, the base plate 11 is connected to a frame, the frame is rotatably connected to wheels, the rear plate 13 is fixedly connected to a support frame, when the support frame is in contact with the ground, the support frame and the wheels together support the vehicle body 1 and maintain the balance of the vehicle body 1; the rear plate 13 is fixedly connected to a push rod, the push rod is used to push the vehicle body 1 to move.

[0045] like Figure 5 As shown, multiple unloading plates 41 are hinged to form an unloading plate 41 chain. Since the hinge 43 is located on the lower side of the unloading plate 41, the hinge 43 can only realize the relative rotation of two unloading plates 41 within a range of 180°, and the rotation direction can only be downward. This prevents the connection of the unloading plates 41 from being recessed downward under the action of the material's gravity, and keeps multiple unloading plates 41 on the same plane for effective support.

[0046] like Figure 3 As shown, the two ends of the roller 42 are rotatably connected to the side plate 12. There are multiple rollers 42, and the multiple rollers 42 are spaced apart at the bottom of the transport trough 2 along the length direction of the base plate 11.

[0047] Understandably, the multiple rollers 42 are spaced apart along the length of the base plate 11, providing a continuous and uniform support surface for the unloading plate 41 chain. This effectively prevents the unloading plate 41 chain from sagging excessively or twisting under heavy load, ensuring that the unloading plate 41 can move smoothly and steadily along the length of the transport trough 2 under the support of the rollers 42. This significantly reduces the risk of jamming or derailment during material pushing, especially for large or irregular materials.

[0048] In one embodiment, there are 3 unloading plates 41 and 4 rollers 42. It is understood that the more rollers 42 there are, the more stable the support for the unloading plates 41 will be, and the less pressure will be on each roller 42.

[0049] like Figure 1 As shown, the side wall is provided with a guide strip 5, which is located on the side of the unloading plate 41 away from the bottom plate 11, to prevent the unloading plate 41 from overturning in the transport trough 2.

[0050] It is understood that the guide bar 5 and the roller 42 are located on both sides of the unloading plate 41, which effectively prevents the unloading plate 41 from rotating in the transport trough 2, thus preventing the push plate 44 from effectively pushing the unloading plate 41 out.

[0051] In some embodiments, the guide bar 5 is located on the side wall near the front plate 14. After the push plate 44 is pushed to a certain position, it will abut against the guide bar 5, but at this time most of the material has been pushed out.

[0052] In some other embodiments, the push plate 44 has a notch corresponding to the guide bar 5 to prevent the guide bar 5 from blocking the push plate 44.

[0053] In one embodiment, the side wall of the roller 42 is recessed to form an annular clearance groove, which is correspondingly provided with the hinge 43 to avoid the hinge 43.

[0054] It should be noted that the hinge 43 includes a first hinge plate and a second hinge plate, which are rotatably connected by a locking pin, and the locking pin protrudes relative to the first hinge plate and the second hinge plate.

[0055] The first hinge plate and the second hinge plate are respectively fixedly connected to the adjacent unloading plates 41.

[0056] It is understood that the annular clearance groove can avoid the protruding part of the hinge 43, thus preventing the hinge 43 from colliding, scratching or getting stuck with the smooth outer surface of the roller 42 during the sliding process of the unloading plate 41.

[0057] like Figure 5 As shown, the unloading plate 41 has a recessed mounting groove 411 on one side near the bottom plate 11. The mounting groove 411 is adapted to the hinge 43, and the hinge 43 is disposed in the mounting groove 411.

[0058] It is understood that the hinge 43 is completely accommodated in the mounting groove 411 recessed in the bottom surface of the unloading plate 41, so that the hinge 43 does not protrude from the bottom surface of the unloading plate 41. In this case, there is no need to provide the clearance groove.

[0059] like Figure 2 As shown, a limiting strip 142 is provided on the side of the front plate 14 away from the bottom plate 11. The limiting strip 142 abuts against the side wall to limit the inward rotation angle of the front plate 14.

[0060] It is understandable that when the front panel 14 rotates inward to a certain angle, the limiting strip 142 will abut against the side wall to form a mechanical limit, thereby restricting the inward rotation angle of the front panel 14.

[0061] like Figure 6 As shown, after the front plate 14 is released from its restriction and flips forward, one side of the limiting strip 142 will rotate around the connection with the bottom plate 11 and abut against the ground. The inner wall of the front plate 14 will form an inclined slide, and the material can slide down along the slide to avoid direct fall and damage to the material.

[0062] like Figure 2 and Figure 4As shown, the limiting strip 142 is provided with the locking boss 141, which is adapted to the hook head of the locking hook 3. When the locking hook 3 is rotated, the hook head abuts against the locking boss 141 to restrict the front plate 14 from flipping outward.

[0063] It is understood that the hook head of the locking hook 3 rigidly abuts against the locking boss 141 on the limiting strip 142 to form a firm mechanical lock, preventing the front plate 14 from flipping outward during transportation or loading due to bumps, material squeezing or accidental collision, thus ensuring transportation safety and preventing material spillage that could cause accidents, waste or environmental pollution.

[0064] like Figure 4 As shown, the locking hook 3 has an insertion hole 31, and the side plate 12 has a through hole 6 corresponding to the insertion hole 31 for inserting a pin 7. The pin 7 passes through the insertion hole 31 and the through hole 6 to restrict the locking hook 3 from rotating relative to the side plate 12.

[0065] It is understood that the locking hook 3 can be rotated to lock and unlock the front panel 14, while the pin 7 can prevent the locking hook 3 from rotating. When the locking hook 3 locks the front panel 14, inserting the pin 7 can prevent the locking hook 3 from rotating and avoid abnormal unlocking due to vibration during transportation.

[0066] It should be noted that one end of the pin 7 is larger than the through hole 6 so as to abut against the locking hook 3.

[0067] Optionally, the push plate 44 is provided with a handle 45 on the side away from the unloading plate 41.

[0068] Understandably, the operator can push the push plate 44 by pushing the handle 45, which facilitates the operator's application of force.

[0069] Optionally, a reinforcing rib 8 is provided between the push plate 44 and the adjacent unloading plate 41 to improve the connection strength between the two and prevent them from bending when the push plate 44 is pushed.

[0070] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
