[0054] The mounting base 1 is provided with a mounting hole 24.

[0055] It further includes a movable chassis, and the movable chassis and the mounting base 1 are connected in a detachable manner;

[0056] The movable chassis includes a support 25, a fixed disk 26, and adjustable legs. The upper end of the support 25 is provided with a plurality of through holes 27.

Moreover, rollers 36 are provided at the lower part of the movable chassis, which facilitates the movement of the crane and makes it convenient to use the crane in places with relatively small space or where the vehicle cannot reach.

[0059] In the specific implementation of the present invention,

[0060] Embodiment 1, as Figures 1 - 4 shown, adopts the driving mode of the motor 20;

[0061] The crane main body is installed and fixed by bolts through the mounting holes 24 on the mounting base 1.

[0062] Start the motor 20 to drive the driving gear 21, and the driving gear 21 meshes with the driven gear 19. Then, the external support pipe 5 and the telescopic mechanism, hoisting mechanism, and angle adjustment mechanism thereon can be driven by the driven gear 19 to rotate, realizing the adjustment of the angle in the horizontal direction.

[0063] Both ends of the first hydraulic cylinder 10 are connected to the first connecting ears 11 on the outer sleeve 8 and the inner rod body 9. Control the telescopic movement of the first hydraulic cylinder 10 to push the inner rod body 9 to telescopic, adjust the overall length of the outer sleeve 8 and the inner rod body 9, and make the front end of the inner rod body 9 located above the item to be hoisted.

[0064] By controlling the telescopic movement of the second hydraulic cylinder 17, adjust the pitching angle of the outer sleeve 8 and the inner rod body 9. Then, remotely control the winch 15 to release the rope 7, hook the item with the hook at the end of the rope 7, and then remotely control the winch 15 to retract the rope 7. Under the guiding and assisting action of the fixed pulley group, the goods can be hoisted smoothly.

[0065] Through the cooperation of the telescopic mechanism, hoisting mechanism, angle adjustment mechanism, and auxiliary rotation mechanism, the goods are hoisted to the designated position.

[0066] Embodiment 2; as Figure 5 shown, adopts the driving mode of the handle 23;

[0067] The crane main body is installed and fixed by bolts through the mounting holes 24 on the mounting base 1.

[0068] Manually push and pull the handle 23, and then drive the external support pipe 5 and the telescopic mechanism, hoisting mechanism, and angle adjustment mechanism thereon to rotate, realizing the adjustment of the angle in the horizontal direction.

[0069] Both ends of the first hydraulic cylinder 10 are connected to the first connecting ears 11 on the outer sleeve 8 and the inner rod body 9. Control the telescopic movement of the first hydraulic cylinder 10 to push the inner rod body 9 to telescopic, adjust the overall length of the outer sleeve 8 and the inner rod body 9, and make the front end of the inner rod body 9 located above the item to be hoisted.

[0070] By controlling the telescopic movement of the second hydraulic cylinder 17, the pitching angle of the outer sleeve 8 and the inner rod 9 is adjusted. Then, the remote-controlled winch 15 releases the rope 7. The hook at the end of the rope 7 hooks the item. Then, the remote-controlled winch 15 retracts the rope 7. Under the guiding and assisting action of the fixed pulley block, the goods are lifted smoothly;

[0071] Through the cooperation of the telescopic mechanism, the winch mechanism, the angle adjustment mechanism, and the auxiliary rotation mechanism, the goods are hoisted to the designated position.

[0072] As Figure 6 shown:

[0073] For some places where vehicles cannot reach, the movable chassis can be installed under the mounting base 1 through bolts. In this way, the crane can be supported by the movable chassis. Moreover, rollers 36 are provided at the lower part of the movable chassis, which facilitates the movement of the crane and is convenient for using the crane in places with a relatively small space or where vehicles cannot reach;

[0074] The angle of the adjustable leg can be rotated and adjusted. It is fixed through the cooperation of the fixing pin 34 and the corresponding adjustment hole 29. In this way, the size of the expansion of the adjustable leg can be adjusted. When the expansion is small, it is convenient to move to a position with a small space for use. When the expansion is large, the crane can be supported more stably. Moreover, the direction of the roller 36 can be rotated and adjusted by loosening the bolt connecting the mounting bracket 32 and the round hole 35, so that the roller 36 and the wheel frame 31 are always in the vertical state, which is convenient for the rotation of the roller 36. After adjustment, tighten the bolt connecting the mounting bracket 32 and the round hole 35.

[0075] In the description of the embodiments of the present invention, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are used to indicate the orientation or position relationship, it is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the product of the invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation of the present invention. In addition, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0076] In addition, if terms such as "horizontal", "vertical", "hanging" are used, it does not mean that the component is required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0077] In the description of the embodiments of the present invention, "a plurality of" represents at least 2.

[0078] In the description of the embodiments of the present invention, it should also be noted that unless otherwise clearly specified and limited, if the terms "set", "installed", "connected", "connected" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0079] The above describes the present invention and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the present invention, design similar structural forms and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
