Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a multifunctional transportation tool. Background Art

[0002] During the construction process, material transportation has always been a key link in the construction. The transportation of large and medium-sized materials often requires more manpower and material resources, and wastes a lot of time. Although conventional transportation tools can reduce the intensity of manual labor, they have single functions and high operating costs. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a multifunctional transportation tool to solve the problem that the transportation tools in the prior art have single functions and high use costs.

[0004] To achieve the above-mentioned object, the present invention provides a multifunctional transport tool and a method for preparing the same, comprising a first frame, a moving assembly, a second frame, a movable support and a limiting assembly;

[0005] The moving assembly is installed at the bottom of the first frame and is used to support and move the first frame;

[0006] The second frame is arranged on the first frame and is movably connected to the first frame through the movable support member, and the second frame can be lifted by the movable support member compared with the first frame to be supported above the first frame;

[0007] The limiting assembly is arranged on the movable support member and can be connected to the first frame in a limiting manner. The limiting assembly is used to fix the position of the second frame after it is lifted on the first frame.

[0008] By adopting this technical solution, after manually applying force to the second frame, the second frame can be lifted relative to the first frame under the action of the movable support, and cooperate with the limit assembly to form two upper and lower supporting placement planes. On the one hand, the single transportable capacity of the transport tool can be increased, and on the other hand, the lifting function of the second frame can be used to realize the lifting and lowering control of the goods after transportation, thereby avoiding the use of other lifting control equipment and reducing the transportation cost of the goods; the combination of the two reduces the labor intensity of manual labor during the transportation of goods, and at the same time realizes the versatility of the transport tool.

[0009] Furthermore, two movable support members are provided, respectively located at two end sides of the second frame.

[0010] By adopting this technical solution, the two movable supports can provide relative stability for the connection between the second frame and the first frame, and provide necessary conditions for the second frame to have a lifting function on the first frame.

[0011] Furthermore, the movable support member includes a third steel tube and two first steel tubes vertically fixed to two ends of the third steel tube, and the two first steel tubes are rotatably connected to the second frame and the first frame respectively.

[0012] By adopting this technical solution, after the two first steel tubes are rotatably connected to the first frame and the second frame respectively, the third steel tube that fixes the two first steel tubes provides a distance between the two rotating connection points, thereby forming a support height when the second frame is lifted on the first frame, and cooperating with the limit assembly to achieve stable support after lifting.

[0013] Furthermore, it also includes an armrest, which is rotatably connected to the first frame. The armrest is also connected to the second frame. The rotation of the armrest on the first frame can pull the second frame to be lifted on the first frame.

[0014] By adopting this technical solution: on the one hand, the handrail can facilitate manual pushing of the transport vehicle, and on the other hand, the handrail can increase the lifting force torque of the second frame, thereby reducing the force required to lift the second frame, thereby reducing manual labor intensity.

[0015] Further, it also includes an inner support rod and a U-shaped member;

[0016] wherein the inner support rod is internally connected to the inner side of the handrail;

[0017] The open end of the U-shaped member is connected to the inner support rod, and the closed end of the U-shaped member passes around the first steel pipe on the second frame at an adjacent position.

[0018] By adopting this technical solution, when the handrail is flipped, the first steel pipe on the second frame can be pulled by the U-shaped part, thereby driving the second frame to complete the corresponding lifting action. At the same time, since the U-shaped frame has a clearance space on the inner side that is adapted to the first steel pipe, after the second frame is lifted and limited, the handrail can be flipped in the opposite direction to be reset, and will not conflict with the position of the first steel pipe, so that it can be used as a manual pushing position, which is convenient for manual pushing of the transport tool through the handrail.

[0019] Furthermore, the limiting assembly includes a hook plate, a fixing card and a cable;

[0020] wherein the hook plate is rotatably connected to the movable support member;

[0021] The fixing card is fixed to the end of the first frame and cooperates with the hook plate;

[0022] One end of the pull cable is connected to the hook plate, and the other end is fixed to the handrail. Pulling the pull cable can drive the hook plate to rotate.

[0023] By adopting this technical solution, after the second frame is lifted up driven by the handrail, pulling the cable can drive the end of the hook plate that is not rotated to rise, so that after the second frame is flipped to the maximum height, the hooking end of the hook plate falls to the outside of the first frame, and then the cable is released. The hook plate can cooperate with the fixing card under the action of its own gravity, thereby completing the pulling and limiting of the second frame, and then completing the height fixation of the second frame.

[0024] Furthermore, the mobile assembly includes universal wheels and directional wheels;

[0025] The universal wheels and the directional wheels are evenly connected to two ends of the bottom of the first frame respectively.

[0026] By adopting this technical solution, the universal wheels and the fixed wheels cooperate to ensure the basic mobility of the transport vehicle, wherein the universal wheels can facilitate the steering of the transport vehicle, and the fixed wheels can prevent the transport vehicle from shifting sideways.

[0027] Further, it also includes a first stopper;

[0028] The first stopper is located on a side of the armrest facing the second frame and is fixed to the first frame, and the first stopper abuts against a side wall of the armrest in a vertical state.

[0029] By adopting this technical solution, the rotation direction of the armrest is limited by the first stopper, ensuring that in addition to being able to drive the second frame to rise, it can also serve as a pushing part to facilitate the movement of the transportation tool.

[0030] Furthermore, it also includes a second stopper;

[0031] The second stopper is located at one end of the second frame close to the handrail and is fixedly connected to the upper side of the second frame.

[0032] By adopting this technical solution: setting a second stop block to limit the objects placed on the second frame, the stability of the second frame when used to support the placed objects is increased, and at the same time, the objects are prevented from falling off from the end close to the handrail and affecting the mechanical structure of the transportation vehicle.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] In the means of transport, the second frame can be lifted compared to the first frame driven by the handrail, thereby forming an upper and lower layer of placement space to increase the single transport volume. At the same time, the second frame provides a lifting function compared to the first frame, and can be used directly as a lifting device, achieving versatility and reducing the labor intensity of cargo transportation.

[0044] After manually flipping the handrail 17, the second frame 1 can be pulled by the handrail 17 to be lifted on the first frame 3, and then fixed in position by the limit assembly to form two upper and lower supporting placement planes. On the one hand, the single transportable capacity of the transport tool can be increased, and on the other hand, the flipping and lifting function of the second frame 1 can be used to realize the lifting and lowering control of the goods after transportation, thereby avoiding the use of other lifting control equipment and reducing the transportation cost of the goods; the combination of the two reduces the labor intensity of manual labor during the transportation of goods, and at the same time realizes the versatility of the transport tool.

[0045] For further information, please see the attached Figure 4 The first frame 3 and the second frame 1 are both rectangular frames formed by connecting square tubes end to end in sequence. At the same time, in order to increase the stability of the frame structure itself, internal support keels 5 are connected to the inner sides of the first frame 3 and the second frame 1.

[0046] Please see attached Figure 1-2 There are two movable support members, which are respectively located at the two end sides of the second frame 1, which can provide relative stability for the movable connection between the second frame 1 and the first frame 3, and provide the necessary prerequisite for the second frame 1 to have a lifting function on the first frame 3;

[0047] For further information, please refer to the attached Figure 2 The movable support includes a third steel tube 11 and two first steel tubes 4 vertically fixed at both ends of the third steel tube 11. The two first steel tubes 4 are rotatably connected to the second frame 1 and the first frame 3 respectively. After the two first steel tubes 4 are rotatably connected to the first frame 3 and the second frame 1 respectively, the third steel tube 11 fixing the two first steel tubes 4 provides a distance between the two rotation connection points, thereby forming a support height when the second frame 1 is lifted on the first frame 3, and cooperating with the limit assembly to achieve stable support after lifting.

[0048] Please see attached Figure 1 , 2 And 5, the multifunctional transport tool also includes an inner support rod 16 and a U-shaped member 13; wherein the inner support rod 16 is internally connected to the inner side of the handrail 17; the open end of the U-shaped member 13 is connected to the inner support rod 16, and the closed end of the U-shaped member 13 bypasses the first steel pipe 4 on the second frame 1 at an adjacent position; when the handrail 17 is flipped, the first steel pipe 4 on the second frame 1 can be pulled by the U-shaped member 13, thereby driving the second frame 1 to complete the corresponding lifting action. At the same time, since the U-shaped frame 13 has a clearance space on the inner side that is adapted to the first steel pipe 4, after the second frame 1 is lifted and limited, the handrail 17 can be flipped in the opposite direction for reset, and will not conflict with the position of the first steel pipe 4, thereby being used as a manual pushing position, so that it is convenient for manual pushing of the transport tool through the handrail 17.

[0049] For further information, see Attachment Figure 5In order to increase the flexibility of the U-shaped member 13 on the inner support rod 16, the open end of the U-shaped member 13 is fixed to the fourth steel tube 14, and the fourth steel tube 14 is sleeved on the inner support rod 16. When the armrest 17 rotates, the U-shaped member 13 can adapt to the position change of the first steel tube 4 on the second frame 1 through the relative rotation of the fourth steel tube 14 and the inner support rod 16, thereby avoiding structural conflict and ensuring the normal flipping of the armrest 17.

[0050] Furthermore, in order to increase the fit between the U-shaped part 13 and the first steel tube 4 and the rotational connection stability of the first steel tube 4 on the second frame 1, the end plate 6 is fixed to the end of the first steel tube 4 passing through the second frame 1, and the closed end of the U-shaped part 13 is arranged between the outer wall of the second frame 1 and the end plate 6. The U-shaped part 13 is limited by the second frame 1 and the end plate 6, thereby ensuring that the U-shaped part 13 will not separate from the second frame 1, thereby ensuring the stability of its relative movement with the second frame 1.

[0051] Furthermore, in order to increase the fit between the armrest 17 and the second frame 1, the lower end of the armrest 17 is rotatably connected to the first steel tube 4 at the corresponding position on the first frame 3 through the second steel tube 8, so that its rotation axis is coaxial with the corresponding rotation point on the first frame 3 when the second frame 1 is lifted, thereby achieving synchronization of the flipping of the armrest 17 and the flipping of the second frame 1.
