[0033] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0034] The embodiment of the utility model provides a locking device for locking a steel drum 10a inside a carriage and solving the technical problem that the loading and unloading process of the steel drum 10a is relatively complicated.

[0035] like Figure 1 and 5As shown, the locking device of this embodiment includes a support unit 10, a mounting seat 20 and a locking unit 30. The support unit 10 is used to be fixedly connected to the vehicle compartment; the mounting seat 20 is movably connected to the support unit 10 for fixing goods; the locking unit 30 is rotatably connected to the support unit 10 or the mounting seat 20. The locking unit 30 can form a locked state and an unlocked state by rotation. When the locking unit 30 is in the locked state, the mounting seat 20 is locked to the support unit 10. When the locking unit 30 is in the unlocked state, the mounting seat 20 is unlocked from the support unit 10.

[0036] Specifically, the locking device is provided with a support unit 10, a mounting seat 20 and a locking unit 30. The locking device can be fixed to the carriage through the support unit 10, and the mounting seat 20 is movably connected to the support unit 10. The mounting seat 20 can be used to fix the steel drum 10a to be transported. The locking unit 30 can form a locked state and an unlocked state by rotation. After the steel drum 10a is fixed, the locking unit 30 forms a locked state by rotating and switching, and the mounting seat 20 is locked, so that the mounting seat 20 and the steel drum 10a are stabilized. When it is necessary to unload the steel drum 10a, the locking unit 30 can be switched to an unlocked state by rotation, the mounting seat 20 is unlocked, and then the mounting seat 20 is detached from the support unit 10, so as to realize the unloading of the steel drum 10a; the locking device can realize the loading and unloading of the steel drum 10a only by rotating the locking unit 30, thereby providing convenience for the loading and unloading of the steel drum 10a.

[0037] In this embodiment, the loading and unloading of the steel barrel 10a can be carried out by manual handling, forklift handling or lifting by a lifting mechanism. When lifting by the lifting mechanism, the lifting mechanism is installed on the side of the carriage. After the steel barrel is lifted by the lifting ears on the steel barrel, the steel barrel is carried along the running guide rail to realize the loading and unloading of the steel barrel.

[0038] In this embodiment, the locking device is mainly used inside the carriage to lock the steel drum 10a transported by the vehicle. Of course, it can also be used to lock other heavy objects other than the steel drum 10a, providing convenience for loading and unloading other goods. When it is used for loading and unloading other goods, its working principle is the same as that of loading and unloading the steel drum 10a.

[0039] It can be understood that the support unit 10 can be any support structure such as a support plate, a support frame, etc. that can be fixed to the bottom wall of the carriage and provide support for the steel barrel 10a.

[0040] It can be understood that the mounting seat 20 can be any seat body structure that can provide installation for the steel barrel 10a and lock the steel barrel 10a, wherein the steel barrel 10a can be fixed to the mounting seat 20 by components such as locks and bolts.

[0041] In this embodiment, Figure 1 and 5 As shown, a mounting groove 21 is provided on the surface of the mounting seat 20, and a plurality of pull ropes 22 are provided at intervals in the circumferential direction of the mounting seat 20. Each pull rope 22 is connected to the surface of the steel drum 10a, thereby stabilizing the steel drum 10a.

[0042] It can be understood that the locking unit 30 can be a screw that is rotatably connected to the support unit 10 or the mounting base 20. The screw is connected to the support unit 10 by rotation and is threadedly connected to the mounting base 20 by rotation, thereby achieving the locking of the mounting base 20, or is connected to the mounting base 20 by rotation and is threadedly connected to the support unit 10 by rotation, thereby achieving the locking of the mounting base 20.

[0043] In one embodiment, Figure 1-3 As shown, the locking unit 30 includes a locking rod 31 and a clamping member 32. The locking rod 31 is rotatably connected to the mounting seat 20, and the clamping member 32 is fixed to the locking rod 31 and can be clamped with the support unit 10 by the rotation of the locking rod 31. Specifically, when the locking rod 31 is rotated to clamp the clamping member 32 with the support unit 10, the upward movement of the locking rod 31 can be limited. Since the locking rod 31 is connected to the mounting seat 20, the mounting seat 20 can be limited and locked. The locking rod 31 is rotated to disengage the clamping member 32 from the support unit 10, so that the mounting seat 20 can be unlocked. Therefore, the locking rod 31 can be rotated to lock and unlock the mounting seat 20, which provides convenience for the disassembly and assembly of the steel drum 10a.

[0044] It can be understood that the mounting seat 20 can be locked with the clamping member 32 by providing a structure such as a clamping groove to achieve locking of the mounting seat 20.

[0045] In one embodiment, Figure 1 , 3 As shown in FIG5 , the locking unit 30 further includes a lock frame 33, which is fixed to the lock rod 31 and is used to be fixedly connected to the carriage through a lock buckle. Specifically, a lock buckle is provided on the bottom wall of the carriage. When the lock rod 31 rotates and locks the mounting seat 20, the lock frame 33 can be buckled by the lock buckle, thereby limiting the rotation of the lock frame 33 to prevent the lock rod 31 from rotating by itself. When the mounting seat 20 needs to be unlocked, the lock frame 33 needs to be unlocked first.

[0046] In this embodiment, Figure 1 , 3 As shown in FIG. 5 , the lock frame 33 extends in the radial direction of the lock rod 31. Specifically, the lock frame 33 extends in the radial direction of the lock rod 31, so that the lock frame 33 can be used as a handle to reduce the force required to rotate the lock rod 31.

[0047] In one embodiment, Figure 1-3As shown, the clamping member 32 is provided with a first abutting surface 321, and the supporting unit 10 is provided with a second abutting surface 11, the second abutting surface 11 is opposite to the mounting seat 20, and the first abutting surface 321 can abut against the second abutting surface 11 through the rotation of the locking rod 31. Specifically, after the first abutting surface 321 abuts against the second abutting surface 11 through the rotation of the locking rod 31, the movement of the locking rod 31 can be restricted by the second abutting surface 11, thereby realizing the locking of the locking rod 31 and the mounting seat 20. When the locking rod 31 rotates in the opposite direction to make the first abutting surface 321 away from the second abutting surface 11, the mounting seat 20 can be unlocked, which provides convenience for loading and unloading of the steel drum 10a.

[0048] In this embodiment, Figure 1 and 5 As shown, the lock frame 33 and the first abutting surface 321 are respectively located on both sides of the lock rod 31. Since the second abutting surface 11 is opposite to the mounting seat 20, the force of the second abutting surface 11 on the first abutting surface 321 is downward, and the support unit 10 can provide a downward locking force for the mounting seat 20, so that the lock frame 33 is always subjected to a force away from the lock buckle, thereby being able to increase the locking force between the lock frame 33 and the lock buckle.

[0049] In this embodiment, Figure 1 , 3 As shown in Figure 5, the locking unit 30 further includes a locking pin 34, which is slidably connected to the locking frame 33. The locking pin 34 is provided with a limiting head 341, and the mounting seat 20 is provided with a locking slot 23. When the locking unit 30 is in the unlocked state, the locking rod 31 rotates to one side of the locking slot 23, and the locking slot 23 is used to accommodate the limiting head 341 to limit the rotation of the limiting head 341. When the locking unit 30 is in the unlocked state, it forms a vertical state. At this time, the locking pin 34 slides to allow the limiting head 341 to enter the locking slot 23, and the locking slot 23 can limit the rotation of the limiting head 341 to prevent the locking rod 31 from rotating by itself.

[0050] In one embodiment, Figure 1-3 As shown, the support unit 10 includes a limiting support frame 12, which is used to limit the horizontal direction of the clamping member 32, and the second abutting surface 11 is provided on the limiting support frame 12. Specifically, the limiting support frame 12 can limit the horizontal direction of the locking rod 31 by limiting the horizontal direction of the clamping member 32, thereby preventing the mounting seat 20 from moving in the horizontal direction, so that the steel drum 10a remains stable during transportation. By limiting the clamping member 32 by the limiting support frame 12, it is not necessary to set other limiting mechanisms of the mounting seat 20, thereby effectively simplifying the structure of the locking device while keeping the steel drum 10a stable.

[0051] In one embodiment, Figure 1-4As shown, the clamping member 32 is also provided with an arc-shaped supporting surface 322, which is opposite to the first abutting surface 321. The support unit 10 also includes a force-bearing surface 121, which is located below the arc-shaped supporting surface 322 and opposite to the arc-shaped supporting surface 322. The arc-shaped supporting surface 322 can be abutted against the force-bearing surface 121 by the rotation of the locking rod 31, and the mounting seat 20 is lifted. Specifically, when the mounting seat 20 is unlocked, the locking rod 31 rotates to make the first abutting surface 321 detach from the second abutting surface 11, and at the same time, the arc-shaped supporting surface 322 of the clamping member 32 can be abutted against the force-bearing surface 121, and then the mounting seat 20 is supported by the reverse action force of the force-bearing surface 121, thereby facilitating the mounting seat 20 to detach from the support unit 10, and providing convenience for the unloading of the steel drum 10a.

[0052] In this embodiment, Figure 1-3 As shown, the force-bearing surface 121 is disposed on the position-limiting support frame 12 .

[0053] In one embodiment, Figure 1 and 5 As shown, the support unit 10 further includes two support seats 13, which are respectively located on both sides of the limiting support frame 12 and are used to support the two ends of the mounting seat 20, and a disassembly and assembly space is formed between the limiting support frame 12 and the support seat 13. Specifically, the support seat 13 can provide support for the mounting seat 20 at both ends of the mounting seat 20, and the limiting support frame 12 is located between the two support seats 13. By cooperating with the locking rod 31, the mounting seat 20 is locked, thereby stabilizing the mounting seat 20. Since a disassembly and assembly space is formed between the limiting support frame 12 and the support seat 13, the disassembly and assembly space can accommodate the fork of a forklift. When the steel drum 10a is loaded, the disassembly and assembly space can accommodate the fork of the forklift, which is convenient for loading the steel drum 10a. When the mounting seat 20 is unlocked, the fork of the forklift extends into the disassembly and assembly space, and then moves upward to lift the mounting seat 20 and the steel drum 10a, thereby facilitating the unloading of the steel drum 10a.

[0054] In one embodiment, Figure 1-2 As shown in FIG. 4 , the position-limiting support frame 12 is provided with a position-limiting installation groove 122 with an upper opening, the position-limiting installation groove 122 extends in the length direction of the support unit 10, and the clamping member 32 is installed in the position-limiting installation groove 122. Specifically, the position-limiting installation groove 122 extends in the length direction of the support unit 10, and the clamping member 32 can be limited in the length direction, thereby limiting the movement of the mounting seat 20 in the length direction of the support unit 10, and the upper opening of the position-limiting installation groove 122 can facilitate the clamping member 32 to escape from the position-limiting support frame 12.

[0055] In one embodiment, Figure 1-3As shown, the clamping member 32 is provided with an annular limiting groove 323, and the limiting support frame 12 is inserted into the annular limiting groove 323. Specifically, the annular limiting groove 323 can limit the clamping member 32 along the width direction of the support unit 10 without affecting the rotation of the locking rod 31, and cooperate with the limiting installation groove 122 to finally limit the horizontal direction of the mounting seat 20.

[0056] The technical solution of the utility model also provides a transport vehicle, including a locking device. Specifically, the locking device is fixed to the bottom of the vehicle compartment through the support unit 10, so as to fix the steel drum 10a on the bottom of the vehicle compartment. By setting the locking device, the transport vehicle can load and unload the steel drum 10a only by rotating the locking unit 30, thereby facilitating the loading and unloading of the steel drum 10a.

[0057] The specific working principle of the transport vehicle provided by the embodiment of the utility model is as follows: the transport vehicle is provided with a locking device. When loading the steel drum 10a, the steel drum 10a is first installed in the installation groove 21 of the installation seat 20, and then the ropes of the installation seat 20 are connected to the steel drum 10a to stabilize the steel drum 10a. Then, the installation seat 20 equipped with the locking rod 31 is installed on the two support seats 13 by inserting a forklift into the bottom of the installation seat 20 or by lifting the steel drum 10a through the lifting ear of the lifting device. The steel drum 10a is supported by two supporting seats 13, and the annular limiting groove 323 of the locking rod 31 clamping member 32 is aligned with the limiting installation groove 122 of the limiting support frame 12, so that the steel drum 10a and the mounting seat 20 are loaded together. After the loading of the mounting seat 20 is completed, the locking rod 31 is rotated by the locking frame 33, so that the first abutting surface 321 and the second abutting surface 11 are abutted, the mounting seat 20 is limited, and then the lock buckle is buckled with the locking frame 33, and the locking frame 33 is locked, and finally the mounting seat 20 is locked;

[0058] When unloading the steel drum 10a, first unlock the lock frame 33, then reversely rotate the lock rod 31 through the lock frame 33 to make the first abutting surface 321 disengage from the second abutting surface 11, unlock the mounting seat 20, and then slide the lock pin 34 to make the limit head 341 enter the lock groove 23 to limit the rotation of the lock frame 33, and then insert the fork of the forklift into the bottom of the mounting seat 20, or lift the steel drum 10a through the lifting mechanism and move the lifting mechanism along the running guide rail to carry the steel drum 10a from the carriage. The above arrangement provides convenience for loading and unloading the steel drum 10a.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
