[0058] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same elements are represented by the same or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0059] refer to Figure 1On the one hand, an oil drum lifting clamp is provided, comprising: a fixed truncated table 51, which has a circular cross-section and a threaded hole coaxially opened on the fixed truncated table 51; a rotating arm 52, at least three rotating arms 52 are evenly arranged on the circumference of the fixed truncated table 51, the first end of each rotating arm 52 is hingedly connected to the fixed truncated table 51, and the second end of each rotating arm 52 is provided with a hook facing the axis of the fixed truncated table 51; an adjusting rod 55, which passes through the fixed truncated table 51 and is threadedly connected to the threaded hole; a rotating seat, the outer wall of which is hingedly provided with a plurality of transmission rods 53, each transmission rod 53 is respectively hingedly connected to the corresponding rotating arm 52, and the first end of the adjusting rod 55 is rotatably connected in the rotating seat; wherein the adjusting rod 55 is axially upper-limited relative to the rotating seat, and the second end of each transmission rod 53 is hinged to the rotating arm 52.

[0060] The number of the rotating arms 52 is set to at least three. It should be understood that only three rotating arms 52 can ensure the stability of fixing the oil drum 6. In this embodiment, the number of the rotating arms 52 is four, and the four rotating arms 52 are evenly connected to the circumference of the fixed truncated table 51. The four rotating arms 52 are better in operation in structure, and the stability of fixing the oil drum 6 is also guaranteed.

[0061] The rotating seat includes: a first round tube 57, on which the adjusting rod 55 is coaxially sleeved; and an articulated seat 54, wherein at least three articulated seats 54 are evenly arranged on the circumferential outer wall of the first round tube 57, and each articulated seat 54 is respectively articulated to one of the transmission rods 53. It should be understood that there are four articulated seats 54, which is the same as the number of the rotating arms 52.

[0062] A stopper is provided on both sides of the adjusting rod 55 relative to the axial direction of the rotating seat. The stopper enables the adjusting rod 55 to be threadedly connected with the fixed truncated table 51 when the adjusting rod 55 is rotated, so as to adjust the distance between the rotating seat and the fixed truncated table 51. When the distance between the two is reduced, the rotating seat pulls each transmission rod 53, and further pulls the rotating arm 52, and one end of the four rotating arms 52 with a hook moves toward the inside, so that the four rotating arms 52 clamp and fix the oil drum 6.

[0063] A hanging ring 56 is provided at the top of the adjusting rod 55, which is used for lifting the mechanical hoisting. As those skilled in the art should understand, when the oil barrel 6 clamp clamps the oil barrel 6 and pulls the oil barrel 6 clamp upward, under the action of the gravity of the oil barrel 6, the force directions of the adjusting rod 55 and the rotating arm 52 are opposite, thereby avoiding the problem of the rotating arms 52 loosening the oil barrel 6.

[0064] refer to Figures 1 to 7In a second aspect, the present application provides an oil drum lifting machine, which is applied with the oil drum lifting fixture as described above, including: a movable chassis 1; a support frame 2, which is arranged on the mobile chassis 1; an actuator 3, which is arranged on the support frame 2, the actuator 3 is height-adjustable on the support frame 2, and can be rotated on the support frame 2, the actuator 3 is connected to the oil drum lifting fixture, the actuator 3 is foldable, and can move the oil drum 6 in the horizontal direction and the vertical direction.

[0065] It should be understood that the mobility of the mobile chassis 1 enables its use in multiple scenarios. In addition, the mobile chassis 1 can be fixed when the hoisting machine is in operation, avoiding the problem of accidental movement of the hoisting machine during operation. The support frame 2 plays a supporting role to ensure the structural stability of the actuator 3 and the structural stability during the hoisting operation. In addition, a counterweight can be added to the mobile chassis 1 to avoid problems such as the hoisting machine tipping over due to the center of gravity shift during the hoisting operation.

[0066] In this embodiment, reference Figure 3 The mobile chassis 1 includes: a load-bearing plate 11, on which the support frame 2 is mounted, and a plurality of mounting holes are provided on the load-bearing plate 11, and other components can be mounted by bolt assemblies; a mounting frame 12, at least four of which are provided on the load-bearing plate 11; and universal wheels 13, which are respectively installed on the mounting frames 12. The mounting frames 12 are arranged to extend outward, which is conducive to ensuring that the center of gravity is on or close to the load-bearing plate 11, and plays a role in avoiding the problem of the hoisting machine tipping over due to the heavy weight of the hoisted object. The universal wheels 13 can be locked, so that the position of the mobile chassis 1 can be fixed.

[0067] In this embodiment, reference Figure 4 The support frame 2 includes: a second circular tube 21, which is vertically arranged on the mobile chassis 1, and a through hole is opened in the radial direction of the second circular tube 21; a support rod 22, at least three support rods 22 respectively connect the second circular tube 21 and the mobile chassis 1, and each adjacent support rod 22 is connected by a connecting rod 23, and the support rod 22 is used to support the second circular tube 21; an axle pin 24, which is penetrated in the through hole of the second circular tube 21.

[0068] The support frame 2 can play the role of diagonal bracing for the second round tube 21. The more the number, the greater the role of the diagonal bracing, and the connecting rod 23 plays the role of strengthening the structural strength. It is understandable that the diagonal bracing can be connected to the weighing plate of the mobile chassis 1 by bolts, so that the support frame 2 can be detached.

[0069] In this embodiment, reference Figure 4 , Figure 5 and Figure 6The actuator 3 includes: a third circular tube 31, which is provided with a plurality of through holes in the radial direction, each of which is distributed along the axial direction of the third circular tube 31, and the third circular tube 31 is arranged in the second circular tube 21 of the support frame 2; a rotating bearing 32, which is arranged at the end of the third circular tube 31, and the outer ring of the rotating bearing 32 is connected to the third circular tube 31; a column 33, which is connected to the inner ring of the rotating bearing 32; an I-beam 39, which is hinged to the top of the column 33; a hand chain hoist 4, which is slidably connected to the I-beam 39, and the hand chain hoist 4 is used to connect the oil drum lifting fixture; a telescopic mechanism, which is respectively connected to the column 33 and the I-beam 39, and is used for the rotation of the I-beam 39 on the column 33.

[0070] The third round tube 31 can be coaxially arranged in the second round tube 21. The through holes on the third round tube 31 have the same aperture as the through holes on the second round tube 21, and can be coaxially penetrated by the shaft pin 24, thereby realizing the relative fixation between the third round tube 31 and the second round tube 21. By axially adjusting the relative position of the third round tube 31 and the second round tube 21, the height direction of the actuator 3 can be adjusted. The rotating bearing 32 provided can realize the rotation of the column 33 in the circumferential direction, ensure the rotatability of the actuator 3, increase the flexibility of the hoisting machine during the hoisting operation, and make the hoisting operation range larger. One end of the I-beam 39 is hinged to the top of the column 33. The I-beam 39 is a cantilever structure. The I-beam 39 of the cantilever structure can rotate around the hinge position with the column 33 within the angle range of 0° to 90°, ensuring that the I-beam 39 can realize that it is nearly parallel or perpendicular to the column 33. The parallel state or the nearly parallel state is the non-working state of the hoisting machine, which is convenient for storage and does not occupy a large space. The hand chain hoist 4 is slidably arranged on the I-beam 39, which ensures that the hand chain hoist 4 can slide in the length direction of the I-beam 39, that is, the oil drum 6 can move in the horizontal direction during the lifting operation, ensuring the flexibility and operating radius of the lifting operation.

[0071] In this embodiment, reference Figure 5 and Figure 6The telescopic mechanism includes: a mounting plate 34, which is arranged on the column 33; a jack 35, whose base is hinged on the mounting plate 34, and the telescopic end of the jack 35 is hinged on the I-beam 39, and the jack 35 is provided with a rocker 36; and a stabilizing rod 37, whose two ends are respectively rotatably connected to the column 33 and the telescopic rod 38 of the jack 35. The mounting plate 34 serves as a platform for installing the jack 35. The jack 35 can realize the rotation of the I-beam 39 around the top of the column 33 and support the I-beam 39 to be vertical to the column 33. The rocker 36 on the jack 35 facilitates the operation of the jack 35, which is more labor-saving. The stabilizing rod 37 is not only rotatable at both ends, but also makes the column 33 and the jack 35 in a triangular state, ensuring the structural stability of the telescopic rod 38 of the jack 35 when supporting.

[0072] refer to Figure 7 The hand chain hoist 4 is slidably connected to the I-beam 39 via a pulley frame; the pulley frame includes a concave-shaped structural member 41 and two sets of pulleys arranged therein, and the concave-shaped structural member 41 is connected to the hand chain hoist 4, so that the hand chain hoist 4 can slide on the I-beam 39.

[0073] The oil drum lifting fixture and oil drum lifting machine provided by the present application are provided with an oil drum lifting fixture that can clamp oil drums 6 of different sizes and specifications, and the gripping strength of the oil drum 6 can be adjusted, thereby avoiding the problem of easy falling off due to insufficient gripping strength of the oil drum 6. The overall structure of the oil drum lifting machine is small, easy to store and transport, and has low use cost. The lifting machine is movable, rotatable, and height-adjustable, which can meet the use in various scenarios. The lifting machine has a cantilever structure of an I-beam 39, and the hoisted oil drum 6 can be moved horizontally in the length direction of the I-beam 39, and the lifting and transportation range is wider. The cantilever structure of the I-beam 39 of the lifting machine can be pitched and folded, and the column 33 can be removed from the support frame 2, ensuring that the lifting machine occupies a small space when stored. The oil drum lifting machine of the present application can meet the use scenarios such as the lifting of the oil drum 6 when refueling the drone, the lifting of the oil drum 6 on the vehicle, and the lifting of the oil drum 6 off the vehicle.
