Description

Technical Field

[0001] The utility model belongs to the technical field of transport vehicles, in particular to a transport vehicle for barrel-shaped objects. Background Art

[0002] In industrial production, oil and liquid chemicals are often stored in round iron or plastic barrels. These barrels have a raised annular rim with varying diameters and heights. They hold large volumes of flammable, explosive, or toxic substances, making them dangerous to transport using forklifts or cranes, and extremely risky to carry manually.

[0003] To reduce labor intensity, existing technologies typically utilize transport trucks to transport barrels. The structure of these trucks can be found in patent CN108249364A, "A Barrel Transport Truck with Adjustable Clamping Mechanism." In existing technologies, including this patent, a placement plate is moved beneath the pallet to lift and move the barrel and pallet together. Direct loading and unloading of the barrel requires additional labor, increasing operational complexity.

[0004] To address this issue, existing patent CN215208314U, "Forklift Barrel Clamping Structure," proposes using symmetrically arranged positioning plates to clamp and carry barrels, reducing the number of steps required for loading and unloading barrels onto pallets. However, the clamping of the two positioning plates relies entirely on corresponding rotating cylinders. To ensure uniform force on the barrel's surface during clamping, both cylinders must be activated simultaneously, increasing the complexity of the structure and manufacturing costs. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and to provide a transport vehicle for barrel-shaped objects.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A transport vehicle for barrel-shaped objects comprises a vehicle body; the vehicle body is provided with a lifting mechanism and two clamping jaws arranged opposite to each other; the lifting mechanism drives the clamping jaws to move up and down relative to the vehicle body, and increases or decreases the distance between the two clamping jaws during the movement to clamp barrel-shaped objects of different diameters.

[0008] Preferably, the vehicle body includes a handle and a frame, the handle is pivotally connected to the frame; and support wheels are provided at the bottom ends of the frames.

[0009] Preferably, the lifting mechanism is provided at a position near the handle at the proximal end of the frame; the handle is pressed down to activate the lifting mechanism, thereby driving the clamping jaws to move toward each other.

[0010] Preferably, a guide rail is provided at the distal end of the vehicle frame, and the top ends of the two guide rails are relatively inclined and fixed; and tracks are provided on the guide rails along their setting direction.

[0011] Preferably, the lifting mechanism is a jack, a lifting block is fixedly provided at its output end, and the output end of the lifting mechanism is centrally arranged on the lifting block; both sides of the lifting block are pivotally connected to the connecting rod; the bottom end of the connecting rod is connected to the track through a slider.

[0012] Preferably, the clamping claw is fixedly connected to the bottom end of the connecting rod through a clamping arm.

[0013] Preferably, the handle is further provided with a handle, and the handle is pulled to drive the output end of the lifting mechanism to reset.

[0014] Preferably, the supporting wheel is a universal wheel.

[0015] The advantages of the technical solution of this utility model are mainly reflected in:

[0016] A lifting mechanism drives the two clamping jaws to move synchronously toward each other, which can adapt to the clamping of barrels with different diameters and ensure that the surface of the object is evenly stressed after clamping the barrel. It can realize the rapid clamping, lifting, transportation and lowering of round barrels. The overall structure is simple and easy to operate.

[0017] The guide rail is tilted on the vehicle body, and the connecting rod is used to realize the up and down movement of the clamping claw, which can meet the needs of clamping barrels of different diameters while reducing processing difficulty and manufacturing costs, and has universal applicability;

[0018] During the process of clamping the barrel, the clamping arm moves along the track on the guide rail, and the track is set at an angle, which is inconsistent with the gravity direction of the barrel, effectively avoiding the occurrence of adverse situations such as the barrel falling off during the clamping process and improving the handling reliability.

[0025] The objectives, advantages, and features of the present invention are illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of the application of the technical solutions of the present invention. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

[0026] In the description of the scheme, it should be noted that the terms "center," "up," "down," "left," "right," "front," "back," "vertical," "horizontal," "inside," and "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are intended only for ease of description and simplification of the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of the scheme, with the operator as a reference, the direction closer to the operator is referred to as the proximal end, and the direction away from the operator is referred to as the distal end.

[0027] like Figures 1 to 2 or Figures 4 and 5 As shown, the utility model discloses a transport vehicle for barrel-shaped objects, including a vehicle body 1. The structure of the vehicle body 1 can refer to the forklift structure in the prior art. Specifically, the vehicle body 1 includes a handle 11 and a frame 12. The handle 11 is pivotally connected to the frame 12, and a handle 111 is also provided on the handle 11. Support wheels 13 are provided at the bottom end of the frame 12. Furthermore, the support wheels 13 are preferably universal wheels; and at least one of the support wheels 13 is provided with a foot brake to limit the position of the vehicle body 1 when transporting barrel-shaped objects.

[0028] like Figure 1 and Figure 4 As shown, the frame 12 is provided with a guide rail 41 at the distal end. The top ends of the two guide rails 41 are tilted relative to each other and fixed. Furthermore, a track 411 is provided on the guide rail 41 along the direction in which it is provided. Since the track 411 is tilted and not aligned with the direction of gravity of the barrel, the barrel is effectively prevented from falling off during the clamping process, thereby improving handling reliability.

[0029] Combine Figure 1 and Figure 3 or Figure 4 and Figure 6As shown, the vehicle body 1 is provided with a lifting mechanism 2 and two clamping jaws 3 disposed opposite to each other. The lifting mechanism 2 drives the clamping jaws 3 to move up and down relative to the vehicle body 1, and increases or decreases the distance between the two clamping jaws 3 during the movement to clamp the barrels of different diameters.

[0030] Specific as Figure 2 and Figure 4 As shown, the jacking mechanism 2 is provided at the proximal end of the frame 12 near the handle 11. The jacking mechanism 2 is a jack, and a jacking block 42 is fixedly provided at its output end, and the output end of the jacking mechanism 2 is centrally provided on the jacking block 42. Since the specific structure and working principle of the jack are known in the prior art, they will not be described in detail here. The two sides of the jacking block 42 are pivotally connected to the connecting rod 43; the bottom end of the connecting rod 43 is connected to the track 411 via a slider. The clamping jaw 3 is fixedly connected to the bottom end of the connecting rod 43 via a clamping arm 31.

[0031] When using a barrel-shaped object transport vehicle to transport the barrel-shaped object, first move the vehicle body 1 toward the barrel-shaped object being transported, and stop after reaching the position. Continuously press down the handle 11 to start the lifting mechanism 2, thereby driving the clamping jaws 3 to move toward each other. Specifically, by pressing down the handle 11, the piston in the jack is pushed upward. At the same time, since the lifting block 42 is fixedly connected to the piston, the lifting block 42 will also move upward synchronously. During the upward movement, the lifting block 42 will drive the top end of the connecting rod 43 to move upward, and the bottom end of the connecting rod 43 will move obliquely upward within the track 411; at the same time, the connecting rod 43 drives the clamping arm 31 to move upward synchronously, so during this process, the distance between the clamping jaws 31 will gradually decrease until it fits with the outer surface of the barrel-shaped object.

[0032] After the handle 11 is further pressed down, the clamping claw 31 will further clamp the barrel and lift the barrel to separate it from the supporting surface; the friction during the movement is reduced, the wear of the barrel is effectively avoided, and the conveying efficiency is improved.

[0033] After reaching the designated unloading position, the handle 111 is pulled to reset the output end of the lifting mechanism 2, i.e., the piston. Simultaneously, the lifting block 42 moves downward, increasing the distance between the two clamping jaws 31, causing the two clamping jaws 31 to gradually move away from the outer wall of the barrel. This releases the force exerted on the barrel as it descends, ensuring that the barrel lands smoothly under the force of the clamping jaws and its own weight. Finally, the vehicle body 1 is removed from the vicinity of the barrel.

[0034] There are many implementation methods for the present utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present utility model.
